FIG. 2 is a side view showing the printer 100 with the open/close cover 11 partially opened. FIG. 3 is a side view showing the entire open/close cover 11 of the printer 100 in an open state. The opening/closing cover 11 can have the entire opening/closing cover 11 open 180 degrees. Furthermore, the openable/closeable cover 11 can have the second side surface portion 1122 opened 180°. FIG. 4 is a schematic diagram showing a back-wound continuous body M. In FIG. 4, the thickness of the wireless tag 6 and the like is illustrated to be thicker than it actually is in order to facilitate understanding. FIG. 5 is a diagram for explaining the communication characteristics of the wireless tag 6 when the continuum M is viewed from the width direction. FIG. 6 is a schematic diagram showing the vicinity of the antenna 42 of the printer 100. FIG. 7 is a diagram for explaining the antenna part radio wave absorber 45. As shown in FIG. FIG. 8 is a schematic diagram showing a cross section of the partition member 51 of the printer 100 when viewed from the side.

For convenience of explanation, as illustrated, a certain horizontal direction is defined as the X direction, a horizontal direction perpendicular to the X direction is defined as the Y direction, and a vertical direction perpendicular to both directions is defined as the Z direction. The X direction is sometimes called the left-right direction, the Y direction is sometimes called the front-back direction, and the Z direction is sometimes called the up-down direction. When viewed from the front, the left side is called "left" and the right side is called "right," and when viewed from the side, the left side is called "front" and the right side is called "rear." Further, the front-rear dimension may be referred to as "length", and the left-right dimension may be referred to as "width". Such notation does not limit the usage position of the printer 100, and the printer 100 can be used in any position.

As shown in FIG. 3, the printer 100 of this embodiment is a printer that prints on wireless tags 6 in a continuum M (see FIG. 4) in which a plurality of wireless tags 6 are provided at predetermined intervals. a printing section 20 that prints on the printing section 20, a conveying path P along which the continuous body M is conveyed in the direction toward the printing section 20 (hereinafter referred to as the conveying direction), a conveying section 7 that conveys the continuous body M in the conveying direction, and a wireless A communication unit 40 that wirelessly communicates with the tag 6, a housing 10 that covers the internal space, and a function that is provided on at least one of a predetermined inner surface of the housing 10 and the internal space to reduce the influence of radio waves on the wireless tag 6. and a functional member 50.

The functional member 50 may have a metal body or a radio wave absorber. The functional members 50 of this embodiment include a partition member 51, an upstream metal body 53, an upstream radio wave absorber 54, a first cover radio wave absorber 56, a second cover radio wave absorber 65, and a bottom radio wave absorber 59. , a downstream radio wave absorber 62 , a bottom metal body 58 , a downstream metal body 61 , and an elongated metal body 67 .

The communication section 40 has an antenna 42 and is provided upstream of the printing section 20 . The communication unit 40 wirelessly communicates with the wireless tag 6 using the antenna 42 .

The printing unit 20 includes a platen roller 24 and a print head unit 22, and prints on the wireless tag 6.

The functional member 50 will be explained. When the communication unit 40 of the printer 100 communicates with the wireless tag 6 to be communicated with, the radio waves from the antenna 42 (predetermined communication radio waves) may reach wireless tags 6 other than the wireless tag 6 to be communicated with. In this case, the radio waves from the communication unit 40 may affect another wireless tag 6, and the printer 100 or another wireless tag 6 may malfunction. From the viewpoint of preventing such malfunctions, it is desirable to be able to reduce the influence of radio waves on other wireless tags 6. Therefore, the printer 100 of this embodiment includes a functional member 50 that has a function of reducing the influence of radio waves on the wireless tag 6. The functional member 50 can be provided on at least one of a predetermined inner surface and the internal space of the housing 10.

The internal space includes a first space 14 that accommodates the printing section 20 and the communication section 40, and a second space 16 that is separate from the first space 14. The functional member 50 includes a partition member 51 that partitions the first space 14 and the second space 16.

In particular, the internal space includes a first space 14 that accommodates the printing section 20 and the communication section 40, a wireless tag 6 that is accommodated in the first space 14 among the plurality of wireless tags 6, and a wireless radio that is accommodated in the first space 14. It has a second space 16 that separates the wireless tag 6 from the tag 6 on the upstream side.

As an example, the functional member 50 may include a partition member 51 that partitions the first space 14 and the second space 16, and an upstream metal body 53 disposed upstream of the communication unit 40.

The upstream metal body 53 is a metal plate disposed upstream of the communication unit 40, and is placed close to the communication unit 40 to suppress the influence of strong radio waves. By providing the upstream metal body 53, the wireless tag 6 on the upstream side of the communication unit 40 is prevented from being energized. The upstream metal body 53 may be placed immediately upstream of the communication section 40.

On the other hand, since the wireless tag 6 fed out from the print medium supply section 30 is easily susceptible to radio waves, a partition member 51 is provided to prevent it from being affected by radio waves.

The overall configuration of printer 100 will be explained. As shown in FIG. 1, the printer 100 includes a printing unit 1 on the right side and a control unit 2 on the left side when viewed from the front.

The printing unit 1 realizes a tag printing function and a tag communication function under the control of the control unit 2. The tag printing function is, for example, a function of printing information such as characters, symbols, figures, barcodes, etc. on the upper paper 6B (see FIG. 4) of the wireless tag 6 temporarily attached to the continuum M. The tag communication function is a function to communicate with the wireless tag 6.

The housing 10 functions as an outer shell of the printing unit 1. The housing 10 includes an openable/closeable cover 11 and a housing main body 12 that supports the openable/closeable cover 11 so as to be openable/closeable.

The housing body 12 includes a front surface 121 , a bottom surface 123 , an inner side surface 124 , and a back surface 125 .

The bottom surface portion 123 is a plate-shaped portion that extends back and forth along the bottom surface of the printing unit 1 .

The front portion 121 is a plate-shaped portion that extends upward from the front end of the bottom portion 123 along the front surface of the printing unit 1 . The front part 121 covers the lower side of the front surface of the printing unit 1, and is provided with a discharge port 106 at the upper part for discharging the printed continuous body M.

The back surface portion 125 is a plate-shaped portion that extends upward from the rear end of the bottom surface portion 123 along the back surface of the printing unit 1 .

The inner side surface portion 124 is a plate-shaped portion that extends upward from the left end of the bottom surface portion 123 along the left side surface of the printing unit 1 . As shown in FIG. 3, the inner side surface portion 124 functions as a base to which the printing section 20, print medium supply section 30, communication section 40, ink ribbon section 34, and functional member 50 are fixed. The inner side surface portion 124 is exposed when the open/close cover 11 is opened. In this example, the front part 121, the back part 125, and the inner side part 124 are fixed to the bottom part 123.

As shown in FIG. 1, the open/close cover 11 includes a front part 111, a side part 112, and a top part 113.

The front portion 111 is a plate-shaped portion that mainly extends vertically along the front surface of the printing unit 1 and covers the upper side of the front surface of the printing unit 1 .

The upper surface portion 113 is a plate-shaped portion that extends from the upper end of the front surface portion 111 toward the rear along the upper surface of the printing unit 1 .

The side surface portion 112 is a plate-shaped portion that extends downward from the right end of the upper surface portion 113 along the right side surface of the printing unit 1 .

The opening/closing cover 11 is provided so as to be openable and closable by a hinge 107 provided at the left end of the upper surface portion 113. One side of the hinge 107 is fixed to the left end of the upper surface section 113, and the other side is fixed to the upper end of the inner side surface section 124. As shown in FIG. 3, the front part 111 and the side part 112 are fixed to the top part 113.

In this embodiment, the side surface portion 112 includes a first side surface portion 1121 and a second side surface portion 1122 that extends below the first side surface portion 1121 when the open/close cover 11 is closed. In this example, the side surface portion 112 has a first side surface portion 1121 and a second side surface portion 1122 that are generally divided into upper and lower halves.

The first side surface portion 1121 and the second side surface portion 1122 are connected by a plurality of (for example, five) hinges 1123. The second side surface portion 1122 is rotatably supported relative to the first side surface portion 1121 around a hinge 1123. As shown in FIG. 2, a portion (second side surface portion 1122) of the opening/closing cover 11 can be opened and closed. Moreover, as shown in FIG. 3, the opening/closing cover 11 can be opened and closed as a whole.

As shown in FIG. 3, the side surface of the housing 10 is opened when the open/close cover 11 is opened. Specifically, in the case 10, one side of the internal space is opened when the open/close cover 11 is opened. As shown in FIG. 3, the internal space includes a first space 14 that accommodates the printing section 20 and the communication section 40, and a second space 16 that is separate from the first space 14. That is, the housing 10 is configured such that the first space 14 and the second space 16 are exposed when the openable cover 11 is opened.

With this configuration, the front sides of the first space 14 and the second space 16 are opened when viewed from the operator. By opening the opening/closing cover 11, the open end side (the side opposite to the inner side surface portion 124) of the support shaft 301 that supports the roll T (roll-shaped continuous body M) is opened, so that the ink ribbon R and the continuous body It becomes possible to replace M and maintain the inside of the unit. The opening direction of the openable cover 11 is the direction in which the front space is opened when the openable cover 11 is opened.

The inside of the printer 100 will be explained. As shown in FIG. 3, inside the printer 100, there is a print medium supply section 30 disposed at the rear, a printing section 20 and a communication section 40 disposed at the front, and an ink ribbon section disposed above the printing medium supply section 30. 34 and a functional member 50 are provided.

The printing unit 20 of this embodiment employs a thermal transfer method in which printing is performed on the continuous body M by transferring ink from an ink ribbon R coated with printing ink. The printing unit 20 may be of a thermal coloring type.

The continuous body M is wound to form a roll T, is held by the print medium supply section 30, and is sequentially unwound from the roll T and conveyed in the conveyance direction. Along the conveyance direction of the continuous body M, the printing medium supplying section 30 side with respect to the printing section 20 is referred to as the upstream side, and the opposite side is referred to as the downstream side. The print medium supply section 30 is located on the most upstream side.

The printing section 20 includes a print head section 22, a platen roller 24 and a lower guide section (not shown) disposed below the print head section 22, and a damper mechanism 26 disposed behind them. The damper mechanism 26 is arranged upstream of the print head section 22 and the platen roller 24.

The lower guide part is a member that extends in the front-rear direction and guides the continuous body M being conveyed.

The print head section 22 is supported so that its front section can swing vertically around a rotation shaft 225 at the rear. The print head section 22 has an open state (indicated by a solid line) in which it is open relative to the platen roller 24 and a closed state (indicated by a broken line) in which it is closed relative to the platen roller 24. In other words, the print head section 22 is configured to be able to be switched between the open state and the closed state by swinging.

In the open state, the front part of the print head section 22 is lifted up and separated from the platen roller 24. In this state, the continuous body M and the ink ribbon R can be set and replaced.

In the closed state, the front part of the print head section 22 is lowered, and the thermal head 222 provided at the front lower part of the head body 221 faces the platen roller 24 with the continuous body M and the ink ribbon R interposed therebetween. In other words, the continuous body M is held between the thermal head 222 and the platen roller 24 together with the ink ribbon R. In the closed state, a paper passage route, which is a conveyance path P for the continuous body M, is formed between the print head section 22, the platen roller 24, and the lower guide section. A discharge port 106 is provided on the downstream side of the paper passing route.

The platen roller 24 is a conveying means that conveys the continuous body M fed out from the print medium supply section 30 to the discharge port 106 along the paper passing route. The surface of the platen roller 24 is covered with an elastic material such as hard rubber. The platen roller 24 is arranged so as to be vertically opposite to the thermal head 222 in the closed state so as to be rotatable in forward and reverse directions.

The platen roller 24 is rotationally driven by a drive mechanism (not shown) that includes a motor, a rotation transmitter, and the like. With the print head section 22 in the closed state, the platen roller 24 rotates in the forward direction, so that the continuous body M is conveyed toward the discharge port 106. In other words, the print head section 22 and the platen roller 24 constitute a conveyance section 7 that pinches and conveys the continuous body M.

A print medium position detection sensor (not shown) is provided between the thermal head 222 and the damper mechanism 26 on the paper passing route of the continuous body M. The print medium position detection sensor detects the position of the wireless tag 6 on the continuous body M by detecting a position detection mark (not shown) provided on the continuous body M. The print medium position detection sensor can be configured by, for example, a light reflection type or a light transmission type sensor.

The damper mechanism 26 is a mechanism that applies tension to the continuous body M. The damper mechanism 26 of this embodiment includes a first damper roller 261 and a second damper roller 262 provided upstream of the first damper roller 261. The first damper roller 261 and the second damper roller 262 are swingably supported so as to apply tension to the continuous body M when the print head section 22 is in the closed state.

The ink ribbon section 34 is a mechanism that supplies and winds up the ink ribbon R coated with printing ink. The ink ribbon section 34 includes a ribbon supply section 341 and a ribbon winding section 342 arranged in front of the ribbon supply section 341.

The ribbon supply unit 341 is a mechanism that rotatably supports the ink ribbon R wound into a roll.

The ribbon winding unit 342 is a mechanism that winds up and collects the printed ink ribbon R.

The ink ribbon R is pulled out from the ribbon supply section 341, passes under the print head section 22, and is wound up by the ribbon winding section 342.

The continuum M will be explained. As shown in FIG. 4, the continuous body M includes a plurality of wireless tags 6 and a band-shaped mount S that supports the plurality of wireless tags 6. A plurality of wireless tags 6 are temporarily attached to the mount S at predetermined intervals along its longitudinal direction.

In order to easily peel off the wireless tag 6, the surface of the mount S (the surface with which the adhesive surface of the wireless tag 6 comes into contact) is coated with a release agent such as silicone. A position detection mark (not shown) indicating the position of the wireless tag 6 is provided on the back surface of the mount S (the surface to which the wireless tag 6 is not attached).

The wireless tag 6 includes an electronic circuit section 6A and a top paper 6B laminated on the front side of the electronic circuit section 6A, and is attached to a mount S with an adhesive 6C. The upper paper 6B is plain paper in this example. The upper paper 6B may be thermal paper. If the printer 100 is of a thermal coloring type, the upper paper 6B is thermal paper.

As shown in FIG. 3, the print medium supply unit 30 holds a roll T of the continuous body M and supplies the continuous body M to the printing unit 20.

The print medium supply section 30 includes a support shaft 301 and a roll guide section 302 provided at one end thereof. The support shaft 301 is a component that rotatably supports the roll T of the continuous body M. The roll guide section 302 is a component that fixes the roll T of the continuous body M. The roll guide section 302 is provided movably along the axial direction of the support shaft 301 so that its position can be changed according to the length of the continuous body M in the width direction.

In the example of FIG. 4, the roll T is reverse-rolled. In the reverse winding, the wireless tag 6 is wound inside the continuous body M. Therefore, the wireless tag 6 is not exposed on the outer circumferential surface of the roll T when the roll T is rolled on the wrong side. In back winding, the continuous body M is unwound downward from a position behind the center of the print medium supply section 30 .

Note that the roll T may be wound on the outside. In front winding, the wireless tag 6 is wound on the outside of the continuous body M. Therefore, during front winding, the wireless tag 6 is exposed on the outer peripheral surface of the roll T. In front winding, the continuous body M is unwound downward from a position in front of the center of the print medium supply section 30 (see FIGS. 10 and 11).

Whether the roll T is front-wound or back-wound, the paper passing route of the continuous body M in the printing section 20 is the same. Further, whether the roll T is front-wrapped or back-wound, the continuous body M is transported with the side on which the wireless tag 6 is temporarily attached facing upward. The surface of the continuum M on which the wireless tag 6 is temporarily attached may be referred to as the printed surface.

In the printer 100, a continuous body M fed out in the form of a sheet from the print medium supply section 30 is conveyed to a paper passing route between the print head section 22 and the platen roller 24 via the damper mechanism 26. The printer 100 causes the heating element of the thermal head 222 to generate heat in a predetermined pattern at a timing based on information detected by the print medium position detection sensor while the continuous body M is being conveyed. As a result, characters, symbols, figures, barcodes, etc. are printed on the wireless tag 6 of the continuum M. After printing, the wireless tag 6 (continuum M) is discharged to the outside of the printer 100 from the discharge port 106.

The electronic circuit section 6A includes an IC chip (not shown) having a CPU (Central Processing Unit), a memory, a tag-side communication circuit, etc., and a tag-side antenna (not shown) for communication.

The wireless tag 6 of this embodiment employs a communication method of Bluetooth (registered trademark) Low Energy (BLE), which is a low power consumption communication mode of Bluetooth (registered trademark). In this case, the communication distance is longer than that of NFC (registered trademark) (Near Field Communication), and the power consumption is lower than that of Wi-Fi (registered trademark).

The wireless tag 6 is configured to start (electronic circuit section 6A operates) when the electric power generated within the wireless tag 6 by a predetermined communication radio wave from the antenna 42 of the communication section 40 exceeds a predetermined electric power. Don't use batteries.

When activated, the wireless tag 6 emits radio waves for communicating with the communication unit 40. That is, the wireless tag 6 can communicate with the communication unit 40 when activated, and cannot communicate with the communication unit 40 when it is not activated.

FIG. 5 is a diagram for explaining the communication characteristics of the wireless tag 6 when the continuum M is viewed from the width direction (X direction in FIG. 3). Specifically, FIG. 5 shows the results in each direction when predetermined communication radio waves are supplied to the wireless tag 6 from each direction orthogonal to the X axis on the YZ plane with the wireless tag 6 positioned on the YZ plane. It shows RSSI (Received Signal Strength Indicator).

In FIG. 5, when a predetermined communication radio wave is supplied to the wireless tag 6 from a specific direction indicated by an arrow, RSSI is not shown. This means that with a predetermined communication radio wave from a specific direction, the power generated within the wireless tag 6 will not exceed the predetermined power, and the wireless tag 6 will not start.

Furthermore, as can be seen from FIG. 5, not only the case where a predetermined communication radio wave is supplied to the wireless tag 6 from a strictly specific direction, but also the case where a predetermined communication radio wave is supplied to the wireless tag 6 from a direction along a specific direction, the wireless tag 6 does not start. In other words, even if the wireless tag 6 of this embodiment is within the reach of the predetermined communication radio waves, it cannot be activated by the predetermined communication radio waves from a direction along a specific direction. Note that, as shown in FIG. 5, the specific direction includes a direction from one side to the other side and a direction from the other side to one side with the wireless tag 6 as a reference. Further, since the specific direction itself also follows the specific direction, the direction along the specific direction includes the specific direction itself.

In this way, the wireless tag 6 is configured such that it cannot be activated by a predetermined communication radio wave from a direction along a specific direction even if it is within the reachable range of the predetermined communication radio wave.

The communication section 40 will be explained. The communication unit 40 includes an antenna 42 that generates predetermined communication radio waves, and a communication circuit 44 connected to the antenna 42. The antenna 42 may be included in the lower guide part.

The communication unit 40 uses the antenna 42 to wirelessly communicate with one wireless tag 6 in the continuum M, which is the wireless tag 6 to be communicated with, at a position facing the antenna 42 .

Next, the control unit 2 will be explained. The control unit 2 includes a CPU, memory, input/output interface, and the like. The control unit 2 can also be composed of a plurality of microcomputers. The control unit 2 receives print instruction data from an external computer (not shown), a detection signal from a print medium position detection sensor, and the like through an input/output interface. The control unit 2 uses a CPU to execute a program stored in a memory, and controls the operations of the thermal head 222, the motor that drives the platen roller 24, the communication section 40, and the like.

The control unit 2 communicates with the wireless tag 6 using the communication section 40. The control unit 2 functions as a reading device that reads information written in the wireless tag 6. The control unit 2 functions as a writing device that writes predetermined information to the wireless tag 6. The control unit 2 does not need to have a function as a writing device.

When communicating with the wireless tag 6 using the communication section 40, the control unit 2 causes the antenna 42 to output a predetermined communication radio wave to activate the wireless tag 6 to be communicated with. The control unit 2 stops outputting the predetermined communication radio waves from the antenna 42 when the wireless tag 6 to be communicated is activated and the communication unit 40 establishes communication (reading and/or writing) with the wireless tag 6 to be communicated. do.

Further, the control unit 2 also stops the output of the predetermined communication radio waves from the antenna 42 when a predetermined time elapses without communication between the wireless tag 6 to be communicated with and the communication unit 40 being established. In this case, the control unit 2 determines that the wireless tag 6 with which communication with the communication unit 40 has not been established is a defective product. The predetermined time is, for example, 5 seconds.

The antenna 42 will be explained with reference to FIGS. 6 and 7. FIG. 6 is a schematic diagram showing the vicinity of the antenna 42. In FIG. 6, a wireless tag 6 that is a communication target is labeled with "(1)", and another wireless tag 6 that is not a communication target is labeled with "(2)" for classification. FIG. 7 is a diagram for explaining the antenna part radio wave absorber 45. As shown in FIG.

As described above, when the communication unit 40 of the printer 100 communicates with the wireless tag 6(1) as the communication target, the radio waves from the antenna 42 (predetermined communication radio waves) are transmitted upstream of the wireless tag 6(1) as the communication target. It may reach another wireless tag 6(2) located nearby or another wireless tag 6(2) located downstream. In this case, the radio waves from the antenna 42 may affect another wireless tag 6(2), and the printer 100 or another wireless tag 6(2) may malfunction. From the viewpoint of preventing such malfunctions, it is desirable to be able to reduce the influence of radio waves on another wireless tag 6(2).

Therefore, in the present embodiment, as shown in FIG. The wireless tag 6(1) and the adjacent wireless tag 6(2) on the downstream side in the transport direction are arranged so as to be located along a specific direction.

To explain in detail, the printer 100 of the present embodiment selects a plurality of wireless tags 6 around the wireless tag 6(1) to be communicated with, and a wireless tag adjacent to the wireless tag 6(1) to communicate on the upstream side in the transport direction. The transport path P is formed such that the direction connecting the wireless tag 6(2), the wireless tag 6(1) to be communicated with, and the adjacent wireless tag 6(2) on the downstream side in the transport direction is a specific direction.

The antenna 42 is provided on the surface of the continuum M opposite to the surface on which the wireless tag 6 is provided.

The antenna 42 is formed in a planar shape, and is arranged close to the continuum M at a position facing the wireless tag 6(1) to be communicated with and parallel to the wireless tag 6(1) to be communicated with. be done. The antenna 42 is arranged parallel to the wireless tag 6(1) to be communicated with because the direction perpendicular to the plane of the antenna 42 is the direction in which the radio waves of the antenna 42 are most strongly output.

In other words, the antenna 42 is placed in a position and attitude where the wireless tag 6(1) exhibits a high RSSI (directly below the wireless tag 6 in FIG. 5) with respect to the wireless tag 6(1) as a communication target.

For the wireless tag 6(2) that is adjacent to the wireless tag 6(1) that is the communication target on the upstream side in the transport direction, the antenna 42 is directed in a direction in which the wireless tag 6(2) is not activated, that is, in a specific direction. arranged along the direction.

Furthermore, the antenna 42 is directed in a direction in which the wireless tag 6(2) is not activated, that is, a specified are arranged along the direction.

In other words, the antenna 42 is connected to the wireless tag 6(2) which is adjacent to the wireless tag 6(1) to communicate with on the upstream side in the conveying direction in the conveyance path P, and to the wireless tag 6(1) to communicate with the wireless tag 6(1) downstream in the conveyance direction. The wireless tag 6(2) is located along a specific direction with respect to the adjacent wireless tag 6(2).

Therefore, in this embodiment, the wireless tag 6(1) to be communicated with and the two adjacent wireless tags 6(2) cannot be activated and do not communicate with the communication unit 40. Therefore, it is possible to reduce the possibility that the communication unit 40 will communicate with a wireless tag 6(2) other than the wireless tag 6(1) to be communicated with.

In this embodiment, the antenna 42 connects at least one wireless tag 6(2) located further upstream than the wireless tag 6(1) to communicate with and the adjacent wireless tag 6(2) on the upstream side in the transport direction. They are also arranged along a specific direction.

Furthermore, the antenna 42 is connected to at least one wireless tag 6(2) located further downstream than the wireless tag 6(1) to communicate with and the adjacent wireless tag 6(2) on the downstream side in the transport direction. are also arranged along a specific direction.

In other words, the antenna 42 is connected to a plurality of wireless tags 6 (2) located upstream in the conveyance direction than the wireless tag 6 (1) to be communicated with on the conveyance path P and to the wireless tags 6 (1) to be communicated with. It is located in a direction along a specific direction with respect to a plurality of wireless tags 6 (2) located on the downstream side of the direction.

Therefore, in this embodiment, there are other wireless tags 6(2) that are not activated in addition to the two wireless tags 6(2) adjacent to the wireless tag 6(1) that is the communication target. Therefore, the possibility that the communication unit 40 will communicate with a wireless tag 6(2) other than the wireless tag 6(1) to be communicated with can be further reduced.

Note that if the antenna 42 is located in a direction along a specific direction with respect to at least one wireless tag 6(2), the communication unit 40 can communicate with the wireless tag 6(2) other than the wireless tag 6(1). This reduces the possibility of communicating with

Therefore, for example, the antenna 42 is connected to the wireless tag 6 (2) that is adjacent to the wireless tag 6 (1) to communicate with on the upstream side in the conveyance direction, and the antenna 42 is adjacent to the wireless tag 6 (1) to be communicated with on the downstream side in the conveyance direction. It may be arranged so that it is located along a specific direction with respect to either one of the matching wireless tags 6(2).

In addition, the antenna 42 is connected to a plurality of wireless tags 6 (2) located upstream in the transport direction than the wireless tag 6 (1) to be communicated with, and to a downstream side in the transport direction than the wireless tag 6 (1) to be communicated with. The wireless tag 6(2) may be placed along a specific direction with respect to any one of the plurality of wireless tags 6(2).

An antenna section radio wave absorber 45 is provided on the opposite side of the continuum M with the antenna 42 in between.

The antenna part radio wave absorber 45 and other radio wave absorbers described in this specification are, for example, conductive radio wave absorbing materials such as conductive fiber fabrics, carbon powder, etc., dielectric materials such as rubber, foamed urethane, foamed polystyrene, etc. It is formed of a dielectric radio wave absorbing material mixed in the body, a magnetic radio wave absorbing material made of a magnetic material such as iron, nickel, ferrite, etc.

By absorbing radio waves output from the surface of the antenna 42 opposite to the continuum M (hereinafter referred to as the bottom surface) by the antenna section radio wave absorber 45, the influence of the radio waves on the wireless tag 6(2) is reduced. Can be reduced.

Specifically, the antenna part radio wave absorber 45 is provided at a distance from the antenna 42 by being formed on the surface of a spacer 46 attached to the lower surface of the antenna 42 . The spacer 46 is made of a material such as resin that has little effect on radio waves.

The reason why the antenna part radio wave absorber 45 is provided apart from the antenna 42 is that when the antenna part radio wave absorber 45 and the antenna 42 are close to each other, the antenna part 42 is outputted from the surface of the antenna 42 on the continuum M side (hereinafter referred to as the upper surface). This is because there is a possibility that the radio waves received by the antenna are absorbed by the antenna part radio wave absorber 45 and become unstable. Therefore, it is preferable that the antenna part radio wave absorber 45 is separated from the antenna 42 by about 5 mm. Note that it is sufficient that the antenna part radio wave absorber 45 can be provided apart from the antenna 42, and the spacer 46 does not necessarily need to be provided.

As shown in FIGS. 6 and 7, the antenna part radio wave absorber 45 has a flat part 45a and a side wall part 45b provided around the flat part 45a and protruding toward the antenna 42, and is formed into a container shape. has been done.

As shown in FIG. 6, the antenna part radio wave absorber 45 is arranged so that the plane part 45a is parallel to the continuum M. That is, the antenna section radio wave absorber 45 is also arranged parallel to the antenna 42. Thereby, the radio waves output from the bottom surface of the antenna 42 can be efficiently absorbed, so that the influence of the radio waves output from the bottom surface of the antenna 42 on the wireless tag 6(2) can be reduced.

Further, by having the side wall portion 45b, the antenna section radio wave absorber 45 can also absorb radio waves that are diagonally diffused out of the radio waves output from the lower surface of the antenna 42. That is, the antenna section radio wave absorber 45 of this embodiment has a structure in which radio waves output from the lower surface of the antenna 42 are unlikely to leak. Thereby, the influence of the radio waves output from the lower surface of the antenna 42 on the wireless tag 6(2) can be further reduced.

Furthermore, since the directivity of the antenna 42 is configured to be strongest in the direction of the wireless tag 6(1) to be communicated with, the influence of radio waves on another wireless tag 6(2) can be further reduced.

The partition member 51 will be explained. The partition member 51 allows the communication unit 40 to communicate with only one wireless tag 6 (wireless tag 6(1) shown in FIG. 6) facing the communication unit 40 among the plurality of wireless tags 6. It is a member that partitions the internal space.

It is desirable that the partition member 51 can efficiently shield radio waves. In the present embodiment, the second space 16 is a space that surrounds the wireless tags 6 on the upstream side of the wireless tags 6 accommodated in the first space 14 among the plurality of wireless tags 6. In this case, the partition member 51 can efficiently reduce the influence of radio waves on the second space 16, which is the space surrounding the wireless tag 6 on the upstream side. The second space 16 separates the wireless tags 6 accommodated in the first space 14 from among the plurality of wireless tags 6, and the wireless tags 6 located upstream of the wireless tags 6 accommodated in the first space 14. It is a space for doing.

As shown in FIG. 3, the partition member 51 of this embodiment is divided into two parts, one of which is fixed to the opening/closing cover 11 and the other to the main body part 12 of the case 10. In this example, the partition member 51 includes a case side partition member 51A fixed to the case main body 12 of the case 10 and an open/close cover side partition member 51B fixed to the open/close cover 11.

When the open/close cover 11 is closed, the open/close cover side partition member 51B is partially adjacent to the housing side partition member 51A. Specifically, the housing side partition member 51A is fixed to the inner side surface portion 124. The housing main body 12 supports the opening/closing cover 11.

In FIG. 3, the opening/closing cover side partition member 51B with the opening/closing cover 11 in a closed state is shown by a broken line. The housing side partition member 51A and the opening/closing cover side partition member 51B may be in contact with each other, or may face each other with a gap smaller than the thickness. The housing side partition member 51A and the opening/closing cover side partition member 51B may be functionally integrated.

The partition member 51 may be divided into three or more pieces. In particular, when the open/close cover 11 is closed, the open/close cover side partition member 51B is combined with the housing side partition member 51A to partition the first space 14 and the second space 16.

As shown in FIG. 3, the tips of each of the housing side partition member 51A and the opening/closing cover side partition member 51B (ends on the opposite side to the fixed side) may have a shape that is inclined with respect to the width direction. Good (not shown). In this case, since the opening/closing cover 11 has an inclined shape, the opening/closing cover 11 can be closed without interference between the housing side partition member 51A and the opening/closing cover side partitioning member 51B.

Furthermore, the tips of the housing side partition member 51A and the opening/closing cover side partition member 51B may have a rounded shape instead of an acute angle (not shown). If the shape is rounded, it is possible to prevent the continuous body M and the ink ribbon R from being caught and damaged when replacing the continuous body M and the ink ribbon R.

FIG. 8 is a schematic diagram showing a cross section of the partition member 51 when viewed from the side. As shown in FIG. 8, the partition member 51 of this embodiment has a partition metal body 52. As shown in FIG. In this case, by shielding the radio waves, the influence of the radio waves on the wireless tag 6 in the second space 16 can be reduced.

The partition metal body 52 and other metal bodies described in this specification are made of iron-based metal, aluminum, or the like.

The partition metal body 52 is a band-shaped member having a predetermined length in the width direction and generally extending vertically. A predetermined portion of the partition metal body 52 may be fixed to the inner side surface portion 124 with a screw or the like.

As shown in FIG. 8, the partition member 51 of this embodiment has a partition radio wave absorber 55. As shown in FIG. In this case, by absorbing the radio waves, the influence of the radio waves on the wireless tag 6 in the second space 16 can be reduced. The partition metal body 52 and the partition radio wave absorber 55 are laminated and integrated.

The partition radio wave absorber 55 and other radio wave absorbers described in this specification are, for example, a conductive radio wave absorbing material such as a woven conductive fiber, a dielectric material such as carbon powder, rubber, foamed urethane, foamed polystyrene, etc. It is formed of a dielectric radio wave absorbing material mixed in the body, a magnetic radio wave absorbing material made of a magnetic material such as iron, nickel, ferrite, etc.

FIG. 8 shows an example in which the partition metal body 52 is stacked on the front side of the partition radio wave absorber 55. However, the partition radio wave absorber 55 may be stacked on the front side of the partition metal body 52. Regarding the laminate of other metal bodies and radio wave absorbers, the front and back or top and bottom of the laminate can be configured as desired.

As shown in FIG. 3, in the present embodiment, the first space 14 is provided with an upstream metal body 53 disposed upstream of the communication unit 40. In this case, the upstream metal body 53 can further reduce the influence of radio waves on the upstream wireless tag 6.

The upstream metal body 53 is provided on the side of the continuous body M on the conveyance path P that is opposite to the printing surface. The upstream metal body 53 is provided downstream of the partition member 51 and adjacent to the upstream side of the communication section 40 . In this case, the influence of radio waves on the wireless tag 6 on the upstream side of the communication unit 40 can be reduced.

The upstream metal body 53 of this embodiment has a predetermined length in the width direction, and extends diagonally downward toward the rear along the conveyance path P of the continuous body M from immediately behind the communication unit 40 (upstream side). It is a band-shaped member that extends to .

The upstream metal body 53 and other metal bodies described in this specification are made of, for example, iron-based metal, aluminum, or the like.

In this embodiment, an upstream radio wave absorber 54 is provided along the surface of the upstream metal body 53. In this case, the influence of radio waves on the upstream wireless tag 6 can be further reduced.

The upstream radio wave absorber 54 may be stacked and integrated over the entire length and width of the upstream metal body 53, or may be stacked and integrated over a portion of the upstream metal body 53. In the laminate of the metal body and the radio wave absorber, including the upstream metal body 53, the front and back or top and bottom of the stack can be arbitrarily configured.

If the length of the upstream metal body 53 in the width direction is smaller than the length of the continuous body M in the width direction, the shielding effect may be insufficient. Therefore, in this embodiment, the length of the upstream metal body 53 in the width direction corresponds to the length of the continuous body M in the width direction. That is, the length of the upstream metal body 53 in the width direction and the length of the continuous body M in the width direction have a predetermined correspondence relationship.

For example, the length of the upstream metal body 53 in the width direction may be greater than or equal to the length of the wireless tag 6 in the width direction, or may be greater than or equal to the length of the continuous body M in the width direction. For example, this correspondence relationship may be such that the widthwise range of the upstream metal body 53 includes the entire widthwise range of the continuous body M. In this case, the lack of shielding effect can be reduced.

As shown in FIG. 3, in the present embodiment, the first space 14 is provided with an elongated metal body 67 disposed upstream of the upstream metal body 53. In this case, the elongated metal body 67 can further reduce the influence of radio waves on the wireless tag 6 upstream of the upstream metal body 53.

The stretched metal body 67 is arranged on the conveyance path P adjacent to the upstream side of the upstream metal body 53. The elongated metal body 67 may be continuous with the upstream metal body 53 or may be separated from it with a gap in between. The stretched metal body 67 is provided on the surface of the continuous body M on the conveyance path P opposite to the printed surface.

The stretched metal body 67 of this embodiment has a predetermined length in the width direction, and is diagonally rearward along the conveyance path P of the continuous body M from immediately behind the upstream side metal body 53 (upstream side). It is a band-shaped member that extends downward.

The length of the stretched metal body 67 in the width direction may be different from the length of the upstream metal body 53 in the width direction. The length in the width direction of the stretched metal body 67 may be at least the length in the width direction of the electronic circuit portion 6A of the wireless tag 6, and preferably the length in the width direction of the print head portion 22. Bye.

The upstream end of the elongated metal body 67 may extend to the bottom part 123 of the housing 10, may be in contact with the bottom part 123, or may be separated from the bottom part 123 via a gap. The upstream end of the elongated metal body 67 may extend to the upstream side of the second damper roller 262.

In addition, if either the bottom metal body 58 or the bottom radio wave absorber 59 is provided on the bottom part 123 of the casing 10, the upstream end of the elongated metal body 67 extends to the bottom part. It may be in contact with the bottom member, or may be separated from the bottom member through a gap.

In this embodiment, the stretched metal body 67 is provided with a stretched radio wave absorber along its surface. In this case, the influence of radio waves on the wireless tag 6 near the stretched metal body 67 can be further reduced. The elongated radio wave absorber provided on the elongated metal body 67 may be laminated and integrated over the entire length and width of the elongated metal body 67, or may be laminated and integrated over a portion of the elongated metal body 67.

By providing the stretched metal body 67, the wireless tag 6 upstream of the upstream metal body 53 on the conveyance path P can be made less susceptible to unnecessary radio waves. In particular, if the arrangement pitch of the wireless tags 6 is small, a plurality of wireless tags 6 may be located on the transport path P on the upstream side of the upstream metal body 53. By providing the elongated metal body 67, in such a case, it is possible to absorb radio waves so as not to affect the radio tag 6.

In this embodiment, a downstream metal body 61 is provided downstream of the communication unit 40 . In this case, the downstream metal body 61 can further reduce the influence of radio waves on the downstream wireless tag 6. The downstream metal body 61 of this embodiment has a predetermined length in the width direction, and has a band-like shape that extends forward from just in front of the communication unit 40 (downstream side) along the conveyance path P of the continuous body M. It is a member of

In this case, the influence of radio waves on the wireless tag 6 on the downstream side can be further reduced. The downstream radio wave absorber 62 may be laminated and integrated over the entire length and width of the downstream metal body 61, or may be laminated and integrated over a portion of the downstream metal body 61.

It is conceivable that the radio waves radiated to the inner surface of the casing 10 are reflected and affect the wireless tag 6. Therefore, in this embodiment, the housing 10 has an openable cover 11 that covers the first space 14 in a closed state, and the openable cover 11 includes a first cover radio wave absorber 56 and a second cover radio wave absorber 56. A cover portion radio wave absorber including a body 65 is provided. In this case, the first cover part radio wave absorber 56 and the second cover part radio wave absorber 65 absorb the radio waves, thereby reducing the influence of reflected radio waves.

The second cover part radio wave absorber 65 extends in parallel to the width direction of the continuous body M when the open/close cover 11 is closed.

In this embodiment, the first cover part radio wave absorber 56 is a front part radio wave absorber attached to the inner surface of the front part 111. For example, the first cover part radio wave absorber 56 is provided in a vertical range from near the top of the front part 111 to near the top of the discharge port 106 .

In this embodiment, the second cover part radio wave absorber 65 is a side part radio wave absorber provided on the side part 112 of the opening/closing cover 11 . In FIG. 3, the second cover part radio wave absorber 65 in a state where the open/close cover 11 is closed is shown by a chain line.

The second cover radio wave absorber 65 has a horizontally elongated rectangular shape in the state shown in FIG. 2, and has a shape in which the lower rear side (the upper rear side in the figure) is cut out into a rectangular shape.

A second cover metal body may be laminated and integrated over the entire length and width of the second cover radio wave absorber 65, or the second cover radio wave absorber 65 may be integrated with the second cover radio wave absorber 65. A second cover metal body may be laminated and integrated on a part of 65. In this embodiment, by providing the second cover part radio wave absorber 65, the influence of radio waves radiated to the side surface part 112 can be reduced.

The second cover radio wave absorber 65 is disposed on the side of the partition member 51 and is partially adjacent to the partition member 51 when the openable cover 11 is closed. The second cover radio wave absorber 65 and the partition member 51 may be in contact with each other or may be slightly apart. With this configuration, leakage of radio waves can be reduced.

In this embodiment, the side surface of the casing 10 is opened when the open/close cover 11 is opened. In the case 10, the first space 14 and the second space 16 are exposed when the openable cover 11 is opened.

The main configuration and effects of the printer 100 according to the present embodiment configured as described above will be explained.

The printer 100 connects a conveyance path P along which a continuous body M in which a plurality of wireless tags 6 are provided at a predetermined interval, which are activated when the electric power generated by a predetermined communication radio wave exceeds a predetermined power, is conveyed in the conveyance direction, and a communication unit 40 that wirelessly communicates with one wireless tag 6 in the continuum M, which is the wireless tag 6(1) to be communicated with, at a position facing the antenna 42 using an antenna 42 generated; 6 cannot be activated by a predetermined communication radio wave from a direction along a specific direction even if it is within the reach of the predetermined communication radio wave, and the antenna 42 is connected to the wireless tag 6(1) to be communicated with on the carrier path P. A direction along the specific direction with respect to at least one of the wireless tags 6(2) adjacent to each other on the upstream side of the direction, the wireless tags 6(1) to be communicated with, and the wireless tags 6(2) adjacent to the downstream side of the transport direction. Located in

According to this, the antenna 42 of the communication unit 40 communicates with the wireless tag 6(1) to communicate with the wireless tag 6(2) adjacent to the wireless tag 6(2) on the upstream side in the conveyance direction, and the wireless tag 6(1) to communicate with the wireless tag 6(1) in the conveyance direction. The wireless tag 6(2) is located along a specific direction with respect to at least one of the adjacent wireless tags 6(2) on the downstream side. Therefore, at least one of the wireless tag 6 (1) to communicate with, the wireless tag 6 (2) adjacent to the upstream side, and the wireless tag 6 (2) adjacent to the downstream side cannot be activated, and the communication unit 40 and the wireless tag 6 (2) cannot be activated. There's nothing to do. Therefore, it is possible to reduce the possibility that the communication unit 40 will communicate with a wireless tag 6(2) other than the wireless tag 6(1) to be communicated with.

The specific direction is a wireless tag 6 (2) that is adjacent to the wireless tag 6 (1) to communicate with on the upstream side in the conveyance direction on the conveyance path P, and a wireless tag 6 (2) that is adjacent to the wireless tag 6 (1) to be communicated with on the downstream side in the conveyance direction. This is the direction to connect the matching wireless tag 6(2).

According to this, the antenna 42 can be easily arranged in a direction along a specific direction for the wireless tag 6(1) to be communicated with and the two adjacent wireless tags 6(2).

The antenna 42 is connected to a plurality of wireless tags 6 (2) located upstream of the communication target wireless tag 6 (1) in the conveyance direction on the conveyance path P and to a plurality of wireless tags 6 (2) located upstream of the communication target wireless tag 6 (1) in the conveyance direction. It is located along a specific direction with respect to at least one of the plurality of wireless tags 6 (2) located downstream.

According to this, it is possible to further reduce the possibility that the communication unit 40 will communicate with a wireless tag 6(2) other than the wireless tag 6(1) to be communicated with.

The wireless tag 6(1) to be communicated is activated with a predetermined communication radio wave.

This enables the communication unit 40 to communicate with the wireless tag 6(1) to be communicated with.

The antenna 42 is formed in a planar shape and is arranged parallel to the wireless tag 6(1) to be communicated with.

According to this, since the wireless tag 6(1) to be communicated with is located in the direction in which the radio waves of the antenna 42 are outputted most strongly, it becomes easier to activate the wireless tag 6(1) to be communicated with. Therefore, power consumption of the printer 100 can be suppressed.

The antenna 42 is provided on the surface of the continuum M opposite to the surface on which the wireless tag 6 is provided.

According to this, the antenna 42 can be easily arranged. Furthermore, the antenna 42 does not become an obstacle when loading the continuous body M onto the conveyance path P.

The antenna 42 is provided close to the continuum M.

According to this, it becomes easier to activate the wireless tag 6(1) to be communicated with. Therefore, power consumption of the printer 100 can be suppressed. Further, the antenna 42 can be easily arranged in a specific direction with respect to at least one of the two wireless tags 6(2) adjacent to the wireless tag 6(1) to be communicated with.

An antenna section radio wave absorber 45 is provided on the opposite side of the continuum M with the antenna 42 in between.

According to this, by absorbing the radio waves outputted from the surface of the antenna 42 opposite to the continuum M (the bottom surface in this embodiment) by the antenna part radio wave absorber 45, the radio waves are transmitted to the wireless tag 6. The impact can be reduced.

The antenna part radio wave absorber 45 has a flat part 45a parallel to the continuum M.

According to this, the radio waves output from the surface of the antenna 42 opposite to the continuum M can be efficiently absorbed.

The antenna part radio wave absorber 45 has a flat part 45a and a side wall part 45b provided around the flat part 45a and protrudes toward the antenna 42, and is formed in a container shape.

According to this, among the radio waves output from the surface of the antenna 42 on the opposite side to the continuum M, it is also possible to absorb radio waves diffused in an oblique direction.

The antenna part radio wave absorber 45 is provided apart from the antenna 42.

According to this, it is possible to suppress the radio waves outputted from the surface of the antenna 42 on the continuum M side (in this embodiment, the upper surface) from being absorbed by the antenna part radio wave absorber 45 and becoming unstable.

The antenna part radio wave absorber 45 is provided at a distance from the antenna 42 by being formed on the surface of a spacer 46 attached to the surface of the antenna 42 opposite to the continuum M.

According to this, a configuration in which the antenna part radio wave absorber 45 is provided apart from the antenna 42 can be easily realized.

The printer 100 includes a printing unit 20 that prints on the wireless tag 6.

According to this, information such as characters, symbols, figures, barcodes, etc. can be printed on the wireless tag 6.

The printer 100 includes a printing section 20 that prints on the wireless tag 6, a conveying section 7 that conveys the continuous body M toward the printing section 20, a communication section 40 that wirelessly communicates with the wireless tag 6, and a housing that covers the internal space. 10, and a functional member 50 that is provided on at least one of a predetermined inner surface and an internal space of the casing 10 and has a function of reducing the influence of radio waves on the wireless tag 6.

According to this, by having the functional member 50, the influence of radio waves on the wireless tag 6 can be reduced.

In this embodiment, the internal space includes a first space 14 that accommodates the printing section 20 and the communication section 40 and a second space 16 that is separate from the first space 14 , and the functional member 50 has the first space 14 and the second space 16 that is separate from the first space 14 . It includes a partition member 51 that partitions the second space 16.

According to this, by having the partition member 51, it becomes difficult for radio waves from the communication unit 40 in the first space 14 to reach the second space 16. Therefore, the influence of the radio waves on the wireless tag 6 in the second space 16 can be reduced.

As described above, according to the present embodiment, the wireless tag 6 faces the antenna 42 within the range from the entrance of the wireless tag 6 in the first space 14 (the space below the partition member 51) to the outlet 106. It is possible to prevent the wireless tags 6 other than the first space from generating electricity, and also prevent the wireless tags 6 located in locations other than the first space from generating electricity. This makes it possible to generate electricity only in one wireless tag 6 facing the antenna 42.

[Second embodiment]
Hereinafter, a printer 100 according to a second embodiment of the present invention will be described with reference to FIG. 9. In the drawings and description of the second embodiment, components and members that are the same or equivalent to those of the first embodiment are given the same reference numerals. Descriptions that overlap with those of the first embodiment will be omitted as appropriate, and configurations that are different from the first embodiment will be mainly described.

FIG. 9 is a side view showing the inside of the printer 100 according to the second embodiment, and corresponds to FIG. 3.

The printer 100 of the second embodiment is different from the first embodiment in that the configuration of the functional member 50 is different, and the other configurations are the same.

The printer 100 of the second embodiment differs from the first embodiment in that the partition member 51 is integrally formed and has a different shape.

As shown in FIG. 9, the partition metal body 52 is a band-shaped member that has a predetermined length in the width direction and generally extends vertically. The partition metal body 52 includes a forward portion 521 , a downward portion 522 , a curved portion 523 , and an inclined portion 524 .

The forward portion 521 extends forward at a position adjacent to the upper surface portion 113.

The downward portion 522 is bent at the front end of the forward portion 521 and extends downward.

The curved portion 523 extends downward from the lower end of the downward portion 522 while being curved to correspond to the outer periphery of the print medium supply section 30 .

The inclined portion 524 is bent forward at the lower end of the curved portion 523 and extends diagonally downward.

In the partition metal body 52, the front portion 521 and the inclined portion 524 may be fixed to the inner side surface portion 124 with screws or the like.

The printer 100 of this embodiment can have the same functions and effects as those of the first embodiment. In addition, in the printer 100 of this embodiment, since the partition metal body 52 is integrated, the number of parts is reduced, assembly is easy, and it is advantageous in terms of cost.

[Third embodiment]
Hereinafter, a printer 100 according to a third embodiment of the present invention will be described with reference to FIGS. 10 and 11. In the drawings and description of the third embodiment, components and members that are the same or equivalent to those of the first embodiment are given the same reference numerals. Descriptions that overlap with those of the first embodiment will be omitted as appropriate, and configurations that are different from the first embodiment will be mainly described.

FIG. 10 is a side view showing the inside of the printer 100 according to the third embodiment, and corresponds to FIG. 3.

FIG. 11 is a schematic diagram showing a front-wound continuum M. In FIG. 10, a front-wound roll T is used in which the wireless tag 6 is wound on the outside of the continuous body M. In this example, the continuous body M is fed out downward from a position in front of the center of the print medium supply section 30.

The printer 100 of the third embodiment differs from the first embodiment in that the configuration of the functional member 50 is different, and the other configurations are the same.

As shown in FIG. 10, the printer 100 of this embodiment differs from the first embodiment in that it includes a follower member 64. As shown in FIG.

The following member 64 contacts an upstream portion M2 of the continuum M on the upstream side of the communication portion 40. In particular, the following member 64 contacts the continuous body M while following the movement of the continuous body M.

When the communication unit 40 of the printer 100 communicates with the wireless tag 6 to be communicated with, the radio waves from the antenna 42 may reach another wireless tag 6 following the wireless tag 6 to be communicated with. In this case, the radio waves from the antenna 42 may affect another wireless tag 6, and the printer 100 or another wireless tag 6 may malfunction. From the viewpoint of preventing such malfunctions, it is desirable to reduce the influence of radio waves on other wireless tags 6. Therefore, the printer 100 of the present embodiment includes a follower member 64 that contacts and follows the upstream portion M2 of the continuum M on the upstream side of the communication portion 40.

The following member 64 contacts the continuum M on the upstream side of the wireless tag 6 that is communicating with the communication unit 40, and continuously follows the movement of the continuum M while being in contact with it. In particular, the following member 64 contacts the surface of the continuous body M along the extending direction of the continuous body M, and continuously follows the plurality of wireless tags 6.

The following member 64 may be a radio wave absorber. The following member 64 is provided so as to come into contact with the wireless tag 6 on the upstream side of the wireless tag 6 facing the antenna 42 . In particular, it is preferable for the following member 64 to follow the wireless tag 6 located on the upstream side of the wireless tag 6 facing the antenna 42 and further upstream from the adjacent wireless tag 6.

It is preferable that the following member 64 follows the wireless tag 6 attached to the portion of the continuous body M that has been released from the roll T set in the print medium supply section 30. This is because the roll T itself set in the print medium supply unit 30 does not substantially react to radio waves because the wireless tags 6 overlap.

The following member 64 of this embodiment has a predetermined length in the width direction, and has a band-like shape that extends generally vertically from the swinging fulcrum 642 toward the swinging end (the other end on the opposite side of the swinging fulcrum 642) 643. It is a member of The following member 64 contacts the upstream side portion M2. In this case, since the distance to the upstream side portion M2 can be minimized, the influence reduction effect can be improved.

The length of the following member 64 in the width direction may be equal to or longer than the length of the wireless tag 6 in the width direction.

The following member 64 has a following part metal body or a following part radio wave absorber. The following member 64 and other radio wave absorbers described in this specification are made by mixing a conductive radio wave absorbing material such as a woven conductive fiber, carbon powder, etc. with a dielectric material such as rubber, urethane foam, or polystyrene foam. It is formed of a dielectric radio wave absorbing material, a magnetic radio wave absorbing material made of a magnetic material such as iron, nickel, ferrite, etc.

There is no limit to the following mechanism of the following member 64. In FIG. 10, the following member 64 follows the upstream side portion M2 by swinging the swinging end 643 about the swinging fulcrum 642. In particular, the following member 64 in this example follows the upstream side portion M2 due to the action of gravity. In this case, the tracking mechanism can be configured simply because the tracking is performed using its own weight. The following member 64 may be configured to follow the upstream portion M2 by being biased by a biasing member such as a spring. In this case, the tracking operation can be stabilized against changes in posture.

As shown in FIG. 10, the swinging end 643 of the follower member 64 is curved in a direction away from the roll T (in this example, forward). In this case, damage to the roll T caused by the swing end 643 can be suppressed.

As shown in FIG. 10, the following member 64 of this embodiment includes a part of the continuous body M pulled out from the roll T of the print medium supply unit 30 and a part of the roll T set in the print medium supply unit 30. It has a shape that covers . In this case, the influence of radio waves on the portion covered by the following member 64 can be effectively reduced.

In FIG. 10, the roll T1 at the maximum outer diameter is shown by a solid line, and the roll T2 at the minimum outer diameter is shown by a broken line. As shown in FIG. 10, the following member 64 swings in response to a change in the outer diameter of the roll T set in the print medium supply section 30 or a change in the position of the continuous body M pulled out from the roll T. In this case, the effect of reducing the influence of radio waves can be stabilized against changes in the outer diameter of the roll T. The following member 64 may be able to respond to changes in position in the front-rear direction and the up-down direction.

As shown in FIG. 10, the following member 64 contacts the printed surface of the continuous body M. The following member 64 is in contact with the print surface of the continuous body M that faces the print head portion 22 on the upstream side of the conveyance path P of the continuous body M from the platen roller 24 and the print head portion 22 . In this case, since the distance from the following member 64 to the wireless tag 6 can be minimized, the influence reduction effect can be improved.

The following member 64 may be configured to contact the surface of the continuous body M opposite to the printed surface. In particular, the following member 64 may be configured to contact the surface of the continuous body M on the opposite side to the printing surface on the upstream side of the continuous body M in the conveyance path P of the continuous body M rather than the platen roller 24 and the print head section 22. In this case, the influence of the following member 64 on the printing surface can be reduced.

The follower member 64 may be configured to apply tension to the continuous body M. In this case, the slack of the continuous body M can be reduced and the conveyance operation can be stabilized.

As shown in FIG. 10, the swinging fulcrum 642 of the following member 64 is provided upstream of the communication unit 40. In this case, compared to the case where the swing fulcrum 642 is provided on the downstream side of the communication section 40, the degree of freedom in arranging the follower member 64 is increased, and the follower member 64 can be arranged near the upstream side portion M2. The swing fulcrum 642 of the following member 64 may be provided downstream of the communication section 40.

As shown in FIG. 10, the swing end 643 of the follower member 64 is provided upstream of the swing fulcrum 642. In this case, the following member 64 can be made to follow the upstream side portion M2 by its own weight.

As shown in FIG. 10, the swing fulcrum 642 of the follower member 64 is arranged above the damper mechanism 26 for applying tension to the continuous body M. In this case, interference between the swing fulcrum 642 and the damper mechanism 26 can be prevented. The swing fulcrum 642 of the follower member 64 may be arranged below the damper mechanism 26. In this case, the follower member 64 can be made longer to improve the radio wave absorption effect.

As shown in FIG. 10, the swing fulcrum 642 of the follower member 64 faces the upstream metal body 53 having a width corresponding to the width direction of the continuous body M. In this case, by narrowing the opposing gap between the swing fulcrum 642 and the upstream metal body 53, it is possible to suppress radio waves leaking from this gap.

In FIG. 10 , the swing fulcrum 642 of the follower member 64 faces the bottom metal body 58 . In this case, by narrowing the opposing gap between the swing fulcrum 642 and the bottom metal body 58, it is possible to suppress radio waves leaking from this gap.

The printer 100 of this embodiment can have the same effects as the first embodiment. In addition, the printer 100 of this embodiment can reduce the influence of radio waves on the wireless tag 6 in the upstream side M2 by absorbing radio waves with the following member 64. Further, since the following member 64 contacts and follows the upstream side portion M2, it moves to follow changes in the position and shape of the upstream side portion M2, and has the effect of reducing the influence of radio waves against changes in position and shape. It can be stabilized.

A printer 100 according to a fourth embodiment of the present invention will be described below with reference to FIGS. 12 to 14. In the drawings and description of the fourth embodiment, components and members that are the same or equivalent to those of the first embodiment are given the same reference numerals. Descriptions that overlap with those of the first embodiment will be omitted as appropriate, and configurations that are different from the first embodiment will be mainly described.

In the description of each of the above embodiments, an example is shown in which the functional member 50 is not provided on the upper surface portion 113 of the openable/closable cover 11, but the present invention is not limited to this. For example, the functional member 50 may include a third cover radio wave absorber 57 as a cover radio wave absorber provided on the top surface 113 of the opening/closing cover 11.

FIG. 13 is a side view showing the printer 100 shown in FIG. 12 with the open/close cover 11 opened 90 degrees. FIG. 14 is a perspective view of the printer 100 of FIG. 12.

The printer 100 of this embodiment includes a third cover radio wave absorber 57 provided on the top surface 113 of the openable cover 11.

In this embodiment, the open/close cover 11 includes a front part 111, a side part 112, and a top part 113.

The front portion 111 is a plate-shaped portion that mainly extends vertically along the front surface of the printing unit 1 and covers the upper side of the front surface of the printing unit 1 .

The upper surface portion 113 is a plate-shaped portion that extends from the upper end of the front surface portion 111 toward the rear along the upper surface of the printing unit 1 .

The side surface portion 112 is a plate-shaped portion that extends downward from the right end of the upper surface portion 113 along the right side surface of the printing unit 1 .

The opening/closing cover 11 is provided so as to be openable and closable by a hinge 107 provided at the left end of the upper surface portion 113. One side of the hinge 107 is fixed to the left end of the upper surface section 113, and the other side is fixed to the upper end of the inner side surface section 124. In this example, the front part 111 and the side part 112 are fixed to the top part 113, and the opening/closing cover 11 opens and closes integrally.

It is conceivable that the radio waves radiated to the inner surface of the casing 10 are reflected and affect the wireless tag 6.

A body 57 is provided. In this case, the first cover radio wave absorber 56 and the third cover radio wave absorber 57 absorb the radio waves to reduce the influence of reflected radio waves. The first cover part radio wave absorber 56 and the third cover part radio wave absorber 57 are band-shaped members having a predetermined length in the width direction.

The first cover part radio wave absorber 56 and the third cover part radio wave absorber 57 are provided on the inner surface of the opening/closing cover 11.

The first cover part radio wave absorber 56 extends in a plane perpendicular to the conveyance direction when the open/close cover 11 is closed.

The third cover part radio wave absorber 57 extends in parallel to the width direction of the continuous body M when the open/close cover 11 is closed.

In this embodiment, the first cover part radio wave absorber 56 is a front part radio wave absorber attached to the inner surface of the front part 111. For example, the first cover radio wave absorber 56 is provided in a vertical range from near the top of the front part 111 to near the top of the discharge port 106 .

In this embodiment, the third cover part radio wave absorber 57 is a top part radio wave absorber that is attached to the inner surface of the top part 113. For example, the third cover part radio wave absorber 57 extends rearward from near the front end of the upper surface part 113 and is provided substantially in the front and rear range of the first space 14 .

In the printer 100 according to the fourth embodiment, the side surface portion 112 is integral (non-divided) and does not include the second cover portion radio wave absorber 65. The printer 100 according to this embodiment may be provided with the second cover part radio wave absorber 65 shown in FIG. 3, or the side part 112 may be divided into a plurality of parts.

The third cover radio wave absorber 57 is disposed above the partition member 51 and partially adjoins the partition member 51 when the open/close cover 11 is closed. The third cover radio wave absorber 57 and the partition member 51 may be in contact with each other or may be slightly apart. With this configuration, leakage of radio waves can be reduced.

[Fifth embodiment]
Hereinafter, a printer 100 according to a fifth embodiment of the present invention will be described with reference to FIGS. 15 and 16. In the drawings and description of the fifth embodiment, components and members that are the same or equivalent to those of the fourth embodiment are given the same reference numerals. Descriptions that overlap with those of the fourth embodiment will be omitted as appropriate, and configurations that are different from the fourth embodiment will be mainly described.

FIG. 15 is a side view showing a state in which the open/close cover 11 of the printer 100 according to the fifth embodiment is opened 90 degrees. FIG. 16 is a side view showing the inside of the printer 100 of FIG. 15.

In this embodiment, a front-wound roll T is used. In this example, the continuous body M is fed out downward from a position in front of the center of the print medium supply section 30.

The printer 100 of this embodiment is different from the fourth embodiment in that it does not include a partition member 51 and that it includes a follower member 64, and the other configurations are the same.

The functional member 50 of this embodiment includes an upstream metal body 53, an upstream radio wave absorber 54, a first cover radio wave absorber 56, a third cover radio wave absorber 57, a bottom radio wave absorber 59, and a downstream radio wave absorber 56. It includes an absorber 62, a bottom metal body 58, a downstream metal body 61, and an elongated metal body 67.

In this embodiment, the upstream metal body 53 is provided downstream of the follower member 64 and adjacent to the upstream side of the communication unit 40 .

Further, the front end of the bottom metal body 58 is located forward of the rear end of the upstream metal body 53, and the rear end of the bottom metal body 58 is located behind the front end of the follower member 64.

As described above, the printer 100 of the present embodiment contacts the wireless tag 6 upstream of the wireless tag 6 communicating with the communication unit 40, and continues contacting the wireless tag 6 according to the movement of the continuum M. It is provided with a following member 64 that follows the target.

According to this configuration, by absorbing the radio waves with the following member 64, the influence of the radio waves on the wireless tag 6 in the upstream side portion M2 can be reduced. Further, since the following member 64 contacts and follows the upstream side portion M2, it moves to follow changes in the position and shape of the upstream side portion M2, and has the effect of reducing the influence of radio waves against changes in position and shape. It can be stabilized.

[Sixth embodiment]
Hereinafter, a printer 100 according to a sixth embodiment of the present invention will be described with reference to FIG. 17. In the drawings and description of the sixth embodiment, components and members that are the same or equivalent to those of the fifth embodiment are given the same reference numerals. Descriptions that overlap with those of the fifth embodiment will be omitted as appropriate, and configurations that are different from the fifth embodiment will be mainly described.

FIG. 17 is a side view showing the inside of the printer 100 according to the sixth embodiment.

In this embodiment, a front-wound roll T is used. In this example, the continuous body M is fed out downward from a position in front of the center of the print medium supply section 30.

The printer 100 of this embodiment is different from the fifth embodiment in that the configuration of the functional member 50 is different, and the other configurations are the same.

As shown in FIG. 17, the printer 100 of this embodiment includes a partition member 51 that partitions a first space 14 that accommodates the printing section 20 and the communication section 40 and a second space 16 that is separate from the first space 14. This embodiment differs from the fifth embodiment in that it includes the following. In this example, the partition member 51 is fixed to the inner side surface portion 124 of the housing body portion 12.

In the present embodiment, the second space 16 is a space surrounding the wireless tags 6 on the upstream side of the wireless tags 6 accommodated in the first space 14 among the plurality of wireless tags 6. In this case, the partition member 51 can efficiently reduce the influence of radio waves on the space surrounding the wireless tag 6 on the upstream side.

The partition member 51 of this embodiment includes a partition metal body 52 and a partition radio wave absorber 55. In this case, by shielding the radio waves with the partition metal body 52, the influence of the radio waves on the wireless tag 6 in the second space 16 can be reduced. By absorbing radio waves with the partition radio wave absorber 55, the influence of the radio waves on the wireless tag 6 in the second space 16 can be reduced. The partition metal body 52 and the partition radio wave absorber 55 are laminated and integrated.

As shown in FIG. 17, the partition metal body 52 is a band-shaped member that has a predetermined length in the width direction and generally extends vertically. The partition metal body 52 includes a forward portion 521 , a downward portion 522 , a curved portion 523 , and an inclined portion 524 .

The forward portion 521 extends forward at a position adjacent to the upper surface portion 113.

The downward portion 522 is bent at the front end of the forward portion 521 and extends downward.

The curved portion 523 extends downward from the lower end of the downward portion 522 while being curved to correspond to the outer periphery of the print medium supply section 30 .

The inclined portion 524 is bent forward at the lower end of the curved portion 523 and extends diagonally downward.

In the partition metal body 52, the front portion 521 and the inclined portion 524 may be fixed to the inner side surface portion 124 with screws or the like.

The partition radio wave absorber 55 may be provided over the entire length and width of the partition metal body 52, or may be provided in a portion thereof.

The printer 100 of this embodiment can have the same operation and effect as the fifth embodiment. In addition, by providing a partition member 51 that partitions the first space 14 that accommodates the printing section 20 and the communication section 40 and the second space 16 that is separate from the first space 14, the antenna in the first space 14 can be This makes it difficult for radio waves from 42 to reach the second space 16. Therefore, the influence of the radio waves on the wireless tag 6 in the second space 16 can be reduced.

Examples of embodiments of the present invention have been described above in detail. Each of the embodiments described above is merely a specific example of implementing the present invention. The content of each embodiment is intended to limit the technical scope of the present invention to the specific configuration of each embodiment described above, and many changes such as changes, additions, and deletions of constituent elements are possible.

Modifications will be described below. In the drawings and description of the modification, the same or equivalent components and members as those in the embodiment are given the same reference numerals. Explanation that overlaps with the embodiment will be omitted as appropriate, and configurations that are different from the embodiment will be mainly explained.

[First modification, second modification]
A first modification and a second modification will be described with reference to FIGS. 18 and 19. FIG. 18 is a schematic diagram showing the following member 64 of the first modification. FIG. 17 is a schematic diagram showing a follower member 64 of a second modification. In order to facilitate understanding, these figures mainly show the continuum M and the follower member 64, and omit descriptions of members that are not important to the explanation.

It has been suggested that placing the following member 64 in a range from immediately upstream of the antenna 42 of the communication unit 40 to downstream of the roll T has a high effect of reducing the influence of radio waves. From this point of view, the follower member 64 in FIGS. 18 and 19 is placed immediately after the antenna 42 on the upstream side.

In the first modification, the follower member 64 extends along the upper surface of the continuous body M in a range from just upstream of the antenna 42 to a position lower than the lower end of the roll T. In this example, the following member 64 curves to follow the curvature of the continuous body M.

The following member 64 is curved in a downward convex shape, and has a substantially J-shape with left and right sides reversed. Since the wireless tag 6 overlaps at the roll T, it is not easily affected by radio waves. Therefore, the following member 64 does not have a portion that covers the roll T.

In the second modification, the follower member 64 extends along the upper surface of the continuous body M in a range from just upstream of the antenna 42 to upstream of the upper end of the roll T. In this example, the following member 64 is curved to follow the curvature of the continuous body M, and has a portion that covers the roll T.

The following member 64 has a downward convex curve and an upward convex curve that are continuous, and has an inclined substantially S-shape.

Although FIGS. 18 and 19 show an example in which the continuum M is a front wrap, the continuum M may be a back wrap.

[Other variations]
The following member 64 may be integrally provided with a following portion metal body. In this case, the following metal bodies may be laminated over the entire length and width of the following member 64, or may be laminated on a portion thereof. Further, a following metal body may be provided on either the front side or the back side of the following member 64.

In the description of the embodiment, the functional members 50 include an upstream metal body 53, an upstream radio wave absorber 54, a first cover radio wave absorber 56, a second cover radio wave absorber 65, a bottom radio wave absorber 59, and a downstream Although an example including all of the side radio wave absorber 62, the bottom metal body 58, the downstream metal body 61, and the elongated metal body 67 has been shown, the present invention is not limited thereto. It is not essential for the functional member 50 to include these. The functional member 50 may not include some or all of these.

In the description of the embodiment, an example is shown in which the entire area is partitioned by the partition member 51, but the invention is not limited to this. The premise is that the entire space is partitioned by partition members 51. However, the partition member 51 may be formed so as to prevent leakage of radio waves from gaps on both sides of the partition member 51 in the width direction.

FIG. 20 is a diagram showing a modification of the partition member 51. As shown in FIG. 20, the partition member 51 may be provided with an insertion hole 516 through which the continuous body M is inserted. Having the insertion hole 516 increases the degree of freedom in designing the partition member 51. It also prevents leakage from both sides.

In the description of the second embodiment, an example was shown in which the partition member 51 is fixed to the housing main body 12, but the present invention is not limited thereto. For example, the partition member 51 may be fixed to the open/close cover 11.

FIG. 21 is a diagram showing a modification in which the partition member 51 is fixed to the open/close cover 11. FIG. 22 is a diagram showing another modification in which the partition member 51 is fixed to the open/close cover 11. These figures are side views showing a state in which the open/close cover 11 is opened 180 degrees. By fixing the partition member 51 to the opening/closing cover 11 in this manner, the circumference of the printing medium supply section 30 becomes wider when the opening/closing cover 11 is open, so that the roll T can be easily replaced.

In FIG. 21, the partition member 51 is divided into a first partition member 51C fixed to the first side surface part 1121 and a second partition member 51D fixed to the second side surface part 1122. The first partition member 51C and the second partition member 51D are combined to form one partition member 51.

Although FIG. 21 shows an example in which all the partition members 51 are fixed to the open/close cover 11, the present invention is not limited to this. For example, the partition member 51 may be divided and provided such that one part is fixed to the housing main body part 12 and the other part is fixed to the opening/closing cover 11. Further, both of them may be combined to form one partition member 51 when the open/close cover 11 is closed.

In the description of the embodiment, an example was shown in which the print medium supply unit 30 does not have the function of applying tension to the continuous body M, but the present invention is not limited to this. When the tension of the continuous body M is weak, it is possible that the continuous body M is unwound excessively and loosens in the middle of the conveyance path P. If the continuum M loosens, the positional relationship with the functional member 50 may change, and the effect of reducing the influence of radio waves on the wireless tag 6 may become lower. For this reason, a tension applying mechanism 31 may be provided in the print medium supply section 30.

FIG. 23 is a perspective view showing a modification of the print medium supply section 30. FIG. 24 is a diagram showing a state in which the roll T is not attached to the print medium supply section 30 of FIG. 23. FIG. 25 is a diagram showing a state in which the roll T is attached to the printing medium supply section 30 of FIG. 23.

The print medium supply section 30 of this modification includes a tension applying mechanism 31. The tension applying mechanism 31 is a mechanism for applying tension to the continuous body M pulled out from the roll T of the print medium supply section 30.

The tension applying mechanism 31 includes a support shaft 301 , a roll guide section 302 , a tension plate 312 , a spring pressing plate 314 , and a biasing member 316 .

The tension plate 312 is a hollow disc-shaped member that contacts the center of the roll T mounted thereon. The tension plate 312 has a hollow portion through which the support shaft 301 is inserted.

The spring retainer plate 314 is a hollow disc-shaped member that is disposed adjacent to the tension plate 312 on the opposite side from the roll T. The support shaft 301 is inserted into a hollow portion of the spring holding plate 314, and the spring holding plate 314 is in contact with the tension plate 312 so as to be relatively rotatable.

The biasing member 316 is arranged on the opposite side of the spring presser plate 314 from the tension plate 312 . The biasing member 316 applies a biasing force toward the roll T to the tension plate 312 via the spring presser plate 314. The biasing member 316 of this modification is a coil spring through which the support shaft 301 is inserted.

As shown in FIG. 24, when the roll T is not attached to the printing medium supply unit 30, there is almost no urging force applied to the tension plate 312, and the tension plate 312 can rotate freely.

As shown in FIG. 25, when the roll T is attached to the printing medium supply section 30, the roll guide section 302 presses the roll T toward the tension plate 312 along the support shaft 301, so that The biasing member 316 is strongly compressed. Therefore, the biasing member 316 applies a large biasing force to the tension plate 312 via the spring pressing plate 314. In this case, the spring presser plate 314 is strongly pressed against the tension plate 312, and the frictional force therebetween increases.

When the continuous body M is fed out in this state and the roll T rotates, a brake is applied to the rotation of the tension plate 312 and the roll T due to the frictional force between the tension plate 312 and the spring holding plate 314. In this manner, the tension applying mechanism 31 can brake the rotation of the roll T by bringing the tension plate 312 into contact with the end of the roll T. As a result, tension is applied to the continuous body M, and the possibility that the continuous body M is unrolled excessively and loosens is reduced.

The method of controlling the output of a predetermined communication radio wave (hereinafter referred to as "energize output" or "electromotive output") for energizing the wireless tag 6 is not limited to the example of the above embodiment.

For example, the energize output (electromotive force output) is set higher during the first period when data is read from the wireless tag 6 to be communicated, and the energize output (electromotive force output) is set higher than during the first period during the second period when data is not read. (electromotive force output) may be lowered. In the second period, the energize output (electromotive output) may be minimized or the energize output (electromotive output) may be stopped.

By controlling the energize output (electromotive force output) in this manner, it is possible to suppress false detection of the wireless tag 6 upstream of the wireless tag 6 to be communicated with in the second period.

The second period includes a waiting period. The standby state is a state in which the power of the module is ON (that is, the printer 100 is ON), but the communication unit 40 does not substantially emit radio waves including electromotive output. The communication unit 40 may be configured to emit radio waves only when printing.

Due to individual differences in the casing 10, the degree of influence of radio waves on the wireless tag 6 may change, resulting in errors. Therefore, the output of the radio wave may be adjusted according to the individual differences in the casings 10 so that the influence of the individual differences in the casings 10 can be reduced.

For example, the radio wave output can be adjusted by providing an adjustment process in the manufacturing process of the printer 100. The configuration also includes a detection section that detects information according to individual differences in the housing 10, and an output adjustment section that increases or decreases the radio wave output according to the detection result of the detection section, and automatically adjusts the output. There may be.

A modification including a front side radio wave absorption plate 69 will be described with reference to FIG. 26. FIG. 26 is a side view showing a modification including a front side radio wave absorbing plate 69.

In the description of the embodiment, an example was shown in which a radio wave absorption plate is not provided on the front surface portion 121 of the housing main body portion 12, but the present invention is not limited to this. As shown in FIG. 26, the printer 100 may be provided with a front side radio wave absorbing plate 69 on the front side 121 of the housing body 12. As shown in FIG. In this case, the front side radio wave absorption plate 69 can reduce the influence of radio waves leaking to the front side of the housing 10. The front side radio wave absorbing plate 69 may include one or both of a radio wave absorber and a metal body.

In FIG. 26, the front side radio wave absorbing plate 69 is attached to the inner surface of the front part 121. In this modification, the front side radio wave absorbing plate 69 has a first portion 692 and a second portion 694.

The first portion 692 is a portion extending upward and downward from near the upper end of the front face portion 121 to near the upper end of the discharge port 106 . The second portion 694 is a portion extending upward and downward from near the bottom of the discharge port 106 to near the bottom end of the front portion 121 .

It is not essential that the front side radio wave absorbing plate 69 has the first portion 692 and the second portion 694, and it is not necessary to have one of them. The upper end position and lower end position of each part of the front side radio wave absorbing plate 69 can be set through experiments depending on the desired level of reduction in the influence of radio waves.

With reference to FIG. 27, a modification including an upstream radio wave absorbing plate 68 disposed upstream of the elongated metal body 67 will be described. FIG. 27 is a side view showing a modification including an upstream radio wave absorption plate 68.

In the description of the embodiment, an example is shown in which no radio wave absorber or metal body is provided upstream of the stretched metal body 67, but the present invention is not limited to this. If the wireless tag 6 has high sensitivity, it may be affected by even weak radio waves. Therefore, as shown in FIG. 27, the printer 100 may be provided with an upstream radio wave absorbing plate 68 on the upstream side of the elongated metal body 67 on the conveyance path P. In this case, the upstream radio wave absorbing plate 68 can reduce the influence of radio waves on the wireless tag 6 upstream of the stretched metal body 67.

The upstream radio wave absorbing plate 68 may include one or both of a radio wave absorber and a metal body. By arranging the upstream radio wave absorbing plate 68 along the continuum M, it is possible to reduce the influence of radio waves on the wireless tags 6 that are not desired to receive radio waves. The upstream radio wave absorbing plate 68 may not be in contact with the continuum M, or may be in contact with the continuum M.

From the viewpoint of reducing the influence of radio waves, the upstream radio wave absorbing plate 68 may be provided on the printing surface side of the continuous body M, or may be provided on the side of the continuous body M opposite to the printing surface. In FIG. 27, the upstream radio wave absorbing plate 68 is provided on the side of the continuous body M opposite to the printed surface. In this case, damage to the printed surface can be reduced.

The upstream radio wave absorbing plate 68 may be formed as a separate member from the elongated metal body 67, or may be formed as a member integrated with the elongated metal body 67.

In the example of FIG. 27, the upstream radio wave absorbing plate 68 extends from the upstream end of the elongated metal body 67 toward the rear of the printer 100. Specifically, the upstream radio wave absorbing plate 68 extends back and forth beyond the damper mechanism 26 to the vicinity of the print medium supply section 30 .

The position of the upstream end of the upstream radio wave absorbing plate 68 can be determined experimentally depending on the desired level of reduction in the influence of radio waves. The length of the upstream radio wave absorbing plate 68 in the width direction may be the same as the length of the stretched metal body 67 in the width direction.

With reference to FIG. 28, a modification including an upper radio wave absorber 70 disposed outside the outlet 106 will be described. FIG. 28 is a side view showing a modification including the discharge port upper side radio wave absorber 70.

As shown in FIG. 28, the printer 100 may be provided with a discharge port upper side radio wave absorber 70 so as to cover the discharge port 106 from the outside.

The upper end of the outlet upper radio wave absorber 70 is attached to the upper side of the outlet 106 on the front surface 121 of the housing main body 12 . The lower end side of the discharge port upper radio wave absorber 70 is a free end. Therefore, the continuous body M discharged from the discharge port 106 is discharged downward while pushing aside the discharge port upper side radio wave absorber 70. In this case, the discharge port upper side radio wave absorber 70 can reduce the influence of radio waves on the wireless tag 6 discharged from the discharge port 106.

The lower end position and width of the discharge port upper radio wave absorber 70 can be set through experiments depending on the desired level of reduction in the influence of radio waves.

With reference to FIGS. 29 and 30, a modification example including a discharge port lower side radio wave absorber 71 disposed outside the discharge port 106 will be described. FIG. 29 is a side view showing a modification including the discharge port lower side radio wave absorber 71. FIG. 30 is a diagram showing how the cutter mechanism 80 operates in a modified example including the discharge port lower side radio wave absorber 71.

As shown in FIG. 29, the printer 100 may be provided with a discharge port lower electromagnetic wave absorber 71 so as to support the continuous body M discharged from the discharge port 106 from below.

The outlet lower radio wave absorber 71 is supported by a swing mechanism 72 attached to the lower side of the outlet 106 on the front surface 121 of the housing main body 12 . The continuous body M discharged from the discharge port 106 contacts the discharge port lower side radio wave absorber 71 due to its own weight. In this case, the discharge port lower side radio wave absorber 71 can reduce the influence of radio waves on the wireless tag 6 discharged from the discharge port 106.

One end of the discharge port lower radio wave absorber 71 extends to the vicinity of the platen roller 24 . Therefore, when operating the cutter mechanism 80, as shown in FIG. 30, the swing mechanism 72 swings the discharge port lower radio wave absorber 71 so that the other end is in a lowered state. Thereby, it is possible to avoid interference between the one end side of the discharge port lower side radio wave absorber 71 and the movable blade 81 of the cutter mechanism 80.

In place of the discharge port lower radio wave absorber 71, a discharge port lower metal body may be provided. In this case as well, the influence of radio waves on the wireless tag 6 discharged from the discharge port 106 can be reduced.

Both the discharge port upper side radio wave absorber 70 and the discharge port lower side radio wave absorber 71 may be provided. In this case, the wireless tag 6 discharged from the discharge port 106 is vertically sandwiched between the discharge port upper side radio wave absorber 70 and the discharge port lower side radio wave absorber 71, so that the influence of radio waves on the wireless tag 6 is reduced. It can be further reduced.

In the description of the embodiment, the electromotive generation of the wireless tag 6 and the writing of information to the wireless tag 6 were shown separately, but these are repeatedly executed as a single writing cycle. The ratio of the electromotive time and the read time in a write cycle may be constant. For example, when the period of the write cycle is 100%, the ratio of the electromotive time may be set to 20%, and the ratio of the read time may be set to 80%.

When the generation time is constant, due to individual differences between the wireless tags 6 and the housings 10, sufficient electricity cannot be generated in one cycle, and retries are repeated several cycles, resulting in a long total time. It may happen. Therefore, the ratio of the electromotive time in the write cycle may be made changeable. For example, the ratio of the electromotive time in the write cycle may be changed from 20% to 60%, and the ratio of the read time may be changed from 80% to 40%. In this case, the number of retries is reduced and the total time can be shortened.

Further, in order to change the ratio of the energization time, a step of setting the ratio of the energization time may be provided. The setting process may be provided in the manufacturing process of the printer 100, may be provided in the process of installing the printer 100, or may be provided in the process of maintaining the printer 100.

In the description of the embodiment, an example was shown in which the printing section 20 performs printing using heat, but the present invention is not limited to this. The printing unit 20 can employ a known printing method such as an inkjet method.

The printer 100 may not include the functional member 50.

Each of the above-mentioned modifications has the same functions and effects as the embodiment.

Any combination of components and variations of the embodiments described above are also useful as embodiments of the invention. A new embodiment resulting from the combination has the effects of the combined embodiments and modifications.
