Description

  The present invention relates to a small-sized label printer that can be carried by a user, for example.

  2. Description of the Related Art In recent years, portable printers, which are small label printers that can be carried by users, have become widespread, for example, for convenience of a person in charge of collection and delivery of a courier. Such a portable printer includes, for example, a mounting portion for a user to wear on his / her waist or the like, and is used by being mounted on the user's waist (for example, Patent Document 1). Such a portable printer (label printer in Patent Document 1) is shown in FIG.

  As shown in FIG. 10, the portable printer 100 is provided with a main body housing 109 with an externally wound label sheet 103 wound in a roll shape so that a label 102 is attached to a mount 101 and the printing surface of the label 102 faces outward. Stored in the sheet storage unit 104. Then, the outer-wrapped label sheet 103 is drawn out and conveyed to the back side of the platen 105 positioned above the sheet storage unit 104 and printed by the thermal head 106 facing the platen 105, and then the state with the mount 101 is maintained. The label 102 is issued from a label discharge port 107 provided in front of the main body housing 109, or the label 102 in a state where the mount 101 is peeled off is issued from the label discharge port 107.

  The label 102 issued in this way is in a state in which the printing surface side faces upward. As a result, a user who wears the portable printer 100 on his / her waist can check the printed content of the label 102 by looking down.

JP 2002-128039 A

  By the way, in addition to the above-described outer-wrapped label paper 103, the inner-wrapped label paper 108 wound in a roll shape so that the printing surface of the label 102 faces inward (in FIG. , Indicated by virtual lines).

  If the inner-wrapped label paper 108 is used for the portable printer 100 that only assumes the use of the outer-wrapped label paper 103, the following problems occur. That is, when the inner-wrapped label sheet 108 stored in the sheet storage unit 104 is pulled out and conveyed to the back side of the main body housing 109 in the platen 105, a sudden angle change occurs in the conveyance path to the thermal head 106. The label 102 conveyed to the site of change peels off from the mount 101 due to the strength of the waist due to a sudden change in angle, causing a problem that the inner-wrapped label paper 108 is jammed in the paper path.

  An object of the present invention is to prevent unintentional peeling of a label from a backing sheet when using an internally wound label sheet in a label printer that issues a label with the label printing surface facing upward.

  The present invention is provided with a paper storage portion for storing a label paper having a label affixed to a mount and wound in a roll shape, a platen positioned above the paper storage portion, and a print head facing the platen. A main body housing, and the label paper stored in the paper storage portion is drawn out and conveyed to the back side of the main body housing in the platen and printed by the print head, and the printed surface side of the label after printing faces up. In a label printer that conveys the label paper so as to face and issues the label, the label paper having the maximum winding diameter stored in the paper storage portion does not protrude to the front side of the vertical projection surface of the platen. The paper storage unit was formed.

  According to the present invention, the label paper is the inner-wrapped label paper by forming the paper storage portion so that the label paper of the maximum winding diameter stored in the paper storage portion does not protrude to the front side of the vertical projection surface of the platen. Even so, the change in the angle of the paper path becomes gradual, thereby preventing the unintentional peeling of the label from the mount when the inner-wrap label paper is used.

  The open cover 5 is provided on the back side of the lower end of the main body 4. The open cover 5 is rotatable with respect to the main body 4. The open cover 5 is detachable from the main body 4. Specifically, as shown in FIG. 4, a protrusion 4 a having an anisotropic cross section is formed on the lower back surface side of both side surfaces of the main body 4. On the other hand, on both side surface portions on one end side of the open cover 5, a groove 5a into which the protrusion 4a enters and is caught is formed. The entrance of the groove 5a is formed to be slightly narrower than the minimum width of the protrusion 4a, and is expanded by being pushed by the protrusion 4a when the protrusion 4a enters and exits. The depth of the groove 5a is formed to be slightly larger than the diameter of the protrusion 4a, whereby the open cover 5 is rotatably held by the main body portion 4.

  Although not particularly shown, the open cover 5 has a locking claw that protrudes from both sides of the open cover 5 and is locked inside the both sides of the main body 4, and the locking claw is moved inward to move the main body 4 is provided with an operation knob for releasing the locked state. When the locking claw is locked to the main body 4, the position of the open cover 5 is fixed to the main body 4.

  A lower portion of the main body housing 2 is provided with a paper storage portion 6 that stores the roll-shaped label paper 3 in a rollable manner with the open cover 5 closed with respect to the main body portion 4. The paper storage unit 6 is opened and closed by opening and closing the open cover 5.

  The main body 4 is provided with a paper guide 7 extending upward from the back surface of the paper storage unit 6 and toward the open cover 5. A thermal head 8 that is a print head is provided in a portion of the main body 4 near the open cover 5 of the paper guide 7. The thermal head 8 is urged toward a platen 9 described later by a spring (not shown).

  On the inner surface of the open cover 5 (the paper storage unit 6 side), a rotatable platen 9 and a label peeling body 10 that is positioned above the platen 9 and extends along the longitudinal direction of the platen 9 are disposed. The platen 9 contacts the thermal head 8 with the open cover 5 closed. Here, the printing unit 11 is formed by the platen 9 and the thermal head 8. The label peeling body 10 is disposed downstream of the thermal head 8 in the paper transport direction.

  FIG. 5 shows a drive system of the platen 9, (a) is a longitudinal side view showing the drive system of the platen 9 in a state where the open cover 5 is opened, and (b) is a platen 9 in a state where the open cover 5 is closed. It is a vertical side view which shows this drive system.

  As shown in FIG. 5, the main body 4 is provided with a motor 12 for rotationally driving the platen 9. As a mechanism 13 for transmitting the driving force of the motor 12 to the platen 9, a gear 14 connected to the motor 12 is provided on the main body 4 side, and fixed to one end of the platen 9 on the open cover 5 side. A gear 15 is provided. Then, in a state where the open cover 5 is closed with respect to the main body part 4 (see FIG. 5B), the gears 14 and 15 are engaged with each other, whereby the driving force of the motor 12 is transmitted to the platen 9. . In this way, the platen 9 is rotationally driven by the driving force of the motor 12 via the transmission mechanism 13, whereby the label paper 3 sandwiched between the platen 9 and the thermal head 8 is conveyed. Thereby, the label paper 3 of the roll part stored in the paper storage unit 6 is pulled out.

  Here, the positional relationship between the thermal head 8 and the paper storage unit 6 will be described. As shown in FIG. 1, the paper storage unit 6 includes a label paper 3 having the maximum winding diameter stored in the paper storage unit 6 on the front side of the vertical projection surface A of the platen (right side of the vertical line B in FIG. 1). It is formed so as not to protrude.

  With such a structure, a printing path 16 is formed as a path of the label sheet 3 to the printing unit 11. The printing path 16 includes an inner winding label paper path 17 (see FIG. 1) and an outer winding label paper path 18 (see FIG. 3). The inner winding label paper path 17 is a substantially straight path from the pulling point of the roll portion of the inner winding label paper 3c stored in the paper storage section 6 to the printing section 11, and the outer winding label paper path 18 is the paper. This is a curved path from the pull-out point of the externally wound label paper 3 d stored in the storage unit 6 to the printing unit 11 along the paper guide 7.

  Further, as shown in FIGS. 1 to 3, the main body 4 is provided with a peeling roller module 19 that is positioned downstream of the platen 9 in the paper conveyance direction. The peeling roller module 19 is mainly composed of a peeling roller 20 that is pressed against the platen 9 by a biasing force of a spring (not shown) and a support member 21 that rotatably supports the peeling roller 20. Here, the label peeling body 10 described above is positioned between the peeling roller 20 and the thermal head 8. The peeling roller module 19 and the label peeling body 10 constitute a peeling portion 19a.

  The peeling roller module 19 is detachable from the main body 4. Here, FIG. 6 is an enlarged perspective view showing a part of the attachment structure of the peeling roller module 19 to the main body 4. Grooves 4 b into which both end portions of the support member 21 are fitted are formed in the main body portion 4. The part which forms the groove | channel 4b of the main-body part 4 has elasticity. A locking hole 4e is formed at the center of each of the upper and lower surfaces 4c, 4d forming the upper and lower surfaces of the groove 4b of the main body 4. On the other hand, locking claws 21 a are formed at both ends of the support member 21. These locking claws 21 a are locked in the locking holes 4 e of the main body 4. Specifically, when both ends of the support member 21 of the peeling roller module 19 are inserted into the groove 4b of the main body 4, the groove 4b is pushed and expanded by the locking claw 21a, and finally the locking claw 21a is engaged. Locked to the stop hole 4e. On the contrary, when the peeling roller module 19 is removed from the groove 4b of the main body 4, the groove 4b is expanded to the locking claw 21a, and finally the locking claw 21a is detached from the locking hole 4e. FIG. 7 shows the portable printer 1 in a state where the peeling roller module 19 is removed and the open cover 5 is closed.

  As shown in FIG. 6, a push switch 22 that is a sensor is provided on a side surface of the groove 4 b of the main body 4. The push switch 22 outputs a detection signal when pressed by the support member 21 of the peeling roller module 19 inserted into the groove 4b.

  As shown in FIGS. 1 and 3, the main body 4 is formed with a label discharge port 23 for discharging the label 3 b between the upper end of the peeling roller module 19. When the peeling roller module 19 is removed (see FIG. 7), the label discharge port 23 is formed between the main body portion 4 and the upper end of the open cover 5. The label discharge port 23 at this time is wider than the label discharge port when the peeling roller module 19 is attached. The open cover 5 is formed with a mount discharge port 24 for discharging the mount 3 a between the lower end of the peeling roller module 19.

  With such a structure, a label discharge path 25 and a mount path 26 are formed as paths of the label paper 3 after the printing unit 11. The label discharge path 25 is a path from the printing unit 11 to the label discharge port 23. The mount path 26 is a path from the printing unit 11 to the mount discharge port 24 through the label peeling body 10, the platen 9, and the peeling roller 20. The label discharge path 25 guides the label sheet 3 or the label 3b obliquely upward so as to be away from the back surface of the main body housing 2 so that the printing surface side of the printed label 3b faces upward. Here, a path constituted by the print path 16 and the label discharge path 25, that is, a path from the paper storage unit 6 to the label discharge port 23 is a label print discharge path 27. Such a label printing discharge path 27 is formed between the open cover 5 and the main body 4 in a state where the open cover 5 is closed with respect to the main body 4.

  A battery 28 (see FIG. 8) as a power source is detachably provided on the main body 4.

  As shown in FIG. 1, a mounting surface 29 that is in close contact with the user's waist is formed on the back surface of the main body 4, and the mounting surface 29 slips on the user's clothes. An anti-slip 30 for reducing the amount and a belt hook 31 that is an attachment portion that is hooked on the belt of the user so as to face the anti-slip 30 are formed.

  Further, on the upper surface of the main body 4, there is provided an operation unit (not shown) composed of a power switch 32 (see FIG. 8), a feed switch 33 (see FIG. 8), and the like.

  Next, the connection of the control system of each part of the portable printer 1 will be described with reference to FIG. The portable printer 1 includes a CPU (Central Processing Unit) 41 that centrally controls each unit, and a ROM (Read Only Memory) 42 in which fixed data such as a program executed by the CPU 41 is written. Also, a RAM (Random Access Memory) 43 that writes variable data such as work data in an updatable manner is connected via a bus line 44. A thermal head driver 45 for driving the thermal head 8, a motor driver 46 for driving the motor 12 connected to the platen 9, a switch circuit 47 to which the push switch 22, the power switch 32 and the feed switch 33 are connected, and various sensors. A sensor circuit 49 connected to 48, an infrared interface 50 for controlling data communication with a host device such as a handy terminal, and the like are connected to the CPU 41 via a bus line 44. The interface is denoted as I / F in the figure.

  In such a configuration, the case where the label peeling issue mode is used will be described. First, as shown in FIG. 2, the peeling roller module 19 is removed from the main body 4, the operation knob is operated to release the locked state between the main body 4 and the open cover 5, the open cover 5 is opened, and the paper is opened. The storage unit 6 is opened, and the roll-shaped label paper 3 is stored in the paper storage unit 6. Then, in the wide space where the open cover 5 is opened, the leading end of the label paper 3 is pulled out to a position covering the thermal head 8, the open cover 5 is closed, and the label paper 3 is sandwiched between the peeling roller 20 and the platen 9. In this manner, the peeling roller module 19 is attached to the main body 4. Thus, the leading end side of the label sheet 3 is set in the mount path 26 so as to be pulled out from the mount discharge port 24 while being bent at an acute angle by the label peeling body 10 and passing between the peeling roller 20 and the platen 9. Such an operation is performed with the main body 4 mounted on the user's waist, and the label paper 3 is placed in a narrow gap between the platen 9 and the thermal head 8 and between the platen 9 and the peeling roller 20. Since it is not an operation to pass through, the label paper 3 can be set very easily.

  When the power switch 32 is turned on in such a state that the label sheet 3 is set, the push switch 22 detects the attachment of the peeling roller module 19 and inputs a detection signal to the CPU 41. The CPU 41 receives the detection signal and sets the operation mode to the label peeling issue mode. Here, a part of the function of the mode setting means for setting the operation mode to the label peeling issue mode or the label continuous issue mode is executed according to the detection result of the push switch 22. And CPU41 controls each part according to label peeling issuing mode, The printing operation to the label 3b based on the printing data input from host machines (not shown), such as a handy terminal, is made. Specifically, the thermal head 8 prints out with a supply voltage from the battery 28. Each time one line is printed, the platen 9 is driven one pitch at a time by the motor 12 using the battery 28 as a drive source, and the label paper 3 is conveyed. In this case, since the mount 3a is conveyed through the mount path 26 in a state where the mount 3a is bent at an acute angle by the label peeler 10, the label 3b advances straight from the mount 3a by the strength of the waist. It peels and is issued from the label discharge port 23 (refer FIG.1 and FIG.3). At this time, the label 3b is issued with the printing surface side facing upward. In this case, the conveyance of the label paper 3 is controlled so that the rear end of the label 3b remains slightly on the mount 3a so that the peeled label 3b does not fall.

  Next, the case of using in the continuous label issue mode will be described. In this case, as shown in FIG. 2, the peeling roller module 19 is removed from the main body 4, the open cover 5 is opened (the procedure is the same as described above), the paper storage 6 is opened, and the roll-shaped The label paper 3 is stored in the paper storage unit 6. Then, in the wide space where the open cover 5 is opened, the leading end of the label paper 3 is pulled out to a position slightly protruding from the thermal head 8, and the open cover 5 is closed as shown in FIG. As a result, the leading end portion of the label paper 3 is not bent by the label peeling body 10 and is set in the label discharge path 25 so as to be drawn directly from the printing unit 11 to the label discharge port 23 side.

  The power switch 32 is turned on in such a state that the label paper 3 is set. In this case, the push switch 22 does not detect the attachment of the peeling roller module 19 and therefore does not output a detection signal. Since there is no detection signal input, the CPU 41 sets the operation mode to the label continuous issue mode. Here, a part of the function of the mode setting means for setting the operation mode to the label peeling issue mode or the label continuous issue mode is executed according to the detection result of the push switch 22. Then, the CPU 41 controls each unit in accordance with the label continuous issue mode, whereby the printing operation on the label 3b based on the printing data input from a host machine (not shown) such as a handy terminal is performed. Specifically, the thermal head 8 prints out with a supply voltage from the battery 28. Each time one line is printed, the platen 9 is driven one pitch at a time by the motor 12 using the battery 28 as a drive source, and the label paper 3 is conveyed. Such an operation is continuously performed for the set number of issued labels. That is, when the printing on the preceding label 3b is completed, the feeding of the label paper 3 is controlled so that the top of the next label 3b is the printing position by the printing unit 11. The printed label sheet 3 proceeds to the label discharge port 23. Such a printing operation is performed for the set number of label issuances. As a result, the label sheet 3 with the set number of printed labels 3b still attached to the mount 3a is issued from the label discharge port 23. At this time, the label 3b is issued with the printing surface side facing upward.

Note that this embodiment, as a label printer, has been described in application to the portable printer 1 of the portable main body housing 2 is attached to a human body, the label printer is not limited to this also the situation, For example, it may be a desktop portable printer installed and used on a desk or the like where the user can see the printing surface of the label 3b from above.

  In addition, attachment of the open cover 5 to the main-body part 4 is not restricted to the structure mentioned above. Here, the modification of attachment of the open cover 5 to the main-body part 4 is demonstrated based on FIG. In this modified example, a pair of elastic mounting plates 62 are provided at the lower end of the main body 61 with an interval for the lower end of the open cover 63 to enter. A protrusion 62 a is formed inside the mounting plate 62. On the other hand, on both sides of the lower end of the open cover 63, holes 64 into which the protrusions 62a are fitted are formed. When the open cover 63 is attached to the mounting plate 62, the projection 62a is pushed by the open cover 63, the mounting plate 62 spreads on both sides, and finally, the hole 64 fits into the projection 62a. Attached to the main body 61. When the open cover 63 is removed from the main body 61, the protrusion 62a is pushed by the open cover 63, the mounting plate 62 spreads on both sides, and finally the hole 64 is removed from the protrusion 64a, and the open cover 63 is removed from the main body. 61 is removed.

  As described above, in the present embodiment, since the label 3b is issued with the printing surface of the label 3b on the upper side, the user wearing the portable printer 1 on his / her waist simply looks down to see the label 3b. The printed contents can be confirmed.

  Further, since the paper storage section 6 is formed so that the label paper 3 having the maximum winding diameter stored in the paper storage section 6 does not protrude to the front side of the vertical projection surface A of the platen 9, the label paper 3 is Whether it is the wound label sheet 3d or the inner-wrapped label sheet 3c, the angle change of the label print discharge path 27, which is a sheet path for guiding the label sheet 3, is moderated. This prevents the label 3b from being peeled off from the mount 3a in the label print discharge path 27 regardless of whether the label paper 3 is an outer-wrapped label paper 3d or an inner-wrapped label paper 3c. Both 3d and internally wound label paper 3c can be used.

  Further, since the open cover 5 is rotatably attached to the main body 4 at the lower end of the main body 4, when the open cover 5 is partially opened, the upper portion of the paper storage 6 is opened and the paper is Since the lower portion of the storage unit 6 is not opened, the label paper 3 is not dropped out of the portable printer 1 by storing the label paper 3 in the paper storage unit 6 in this state. Can be easily performed.

As described above, in the present embodiment, the peeling roller 20 that conveys the mount 3a after the label 3b has been printed on the platen 9 is rotatably provided and is detachably provided on the main body housing 2. a peeling roller module 19 that is, between the thermal head 8 and the peeling roller 20 provided on the main body housing 2, a label peeling member 10 for peeling the label 3b from the mount 3a, by providing, as the platen 9 peeling It is possible to facilitate the setting of the mount 3a with the roller 20.

  Further, in the label continuous issue mode, the label discharge port 23 is largely opened by removing the peeling roller module 19 from the main body 4, so that the label paper 3 to be issued can be easily taken out. .

  In the present embodiment, the operation mode is changed to the label peeling issue mode or the push switch 22 that is a sensor for detecting whether or not the peeling roller module 19 is attached to the main body housing 2 and the detection result of the push switch 22. By providing a mode setting means for setting the continuous label issuing mode, the user can detach and attach the peeling roller module 19 as necessary or unnecessary even if the user does not consciously set the operation mode at the time of printing. Thus, the operation mode corresponding to the label issuing mode is automatically set, so that it is possible to prevent inconvenience such as defective printing due to forgetting to change the operation mode.

  In the present embodiment, the main body housing 2 is configured, and the main body portion 4 is a first housing to which the print head 8 is attached. The main body housing 2 is configured, and the platen 9 is attached to the main body portion 4. The open cover 5 is a second housing attached to the main body 4 so as to be openable and closable, the battery 28 is a power source provided in the main body 4, and the power is provided by the battery 28 provided in the main body 4. By providing the motor 12 and the transmission mechanism 13 that transmits the driving force of the motor 12 to the platen 9 in a state where the open cover 5 is closed with respect to the main body 4, an electric system is provided on the open cover 5 side. Since there are no parts, it is not necessary to provide a harness on the open cover 5. Here, for example, when an electrical component is present in the open cover 5, a harness cover for protecting the harness provided on the open cover 5 is necessary. In this embodiment, such a harness is used. Since no cover is required, the structure of the open cover 5 can be simplified.

  Further, in the present embodiment, the open cover 5 that is the second housing is provided detachably with respect to the main body 4 that is the first housing, so that the outer side of the roll-shaped label paper 3 is removed.
