Next, the internal structure of the printer 1 will be described with reference to FIGS. 7 and 8. FIG. 7 is a schematic configuration diagram showing the inside of the printer of FIG. 1 in the peeled issuance state through the side surface side, and FIGS. 8 (a) and 8 (b) are schematic configurations showing the main part of the printer of FIG. 7 in an enlarged manner. It is a figure.

As shown in FIG. 7, the printing main body 26 is installed in the opening 2a of the main body case 2 in a state of being adjacent to the paper accommodating portion 6. The printing body unit 26 is a functional unit for printing on the label PL of the label continuum P, and includes a head bracket 27, a thermal head (printing head unit) 28 (see FIG. 8B), and a coil spring 29 (see FIG. 8B). (See FIG. 8), a peeling unit 4, and a battery accommodating portion 33 (see FIG. 7).

The head bracket 27 is a member that holds the open / close cover portion 3 in the closed state. The head bracket 27 is installed in the main body case 2 described above in a swingable state about the rotation shaft 27a on the opposite side of the platen roller 10 at the closed position of the opening / closing cover portion 3.

A groove 27b is formed in the head bracket 27. By fitting the platen shaft 10a of the platen roller 10 into the groove 27b, the opening / closing cover portion 3 is held by the head bracket 27.

Further, the head bracket 27 is formed with a pressing portion 27c. The pressing portion 27c is arranged at a position (directly below) facing the cover open button 18 shown in FIG. 1. When the cover open button 18 is pressed, the pressing portion 27c is also pushed, and the opening / closing cover portion 3 by the head bracket 27 is pressed. The holding state of is released. Then, when the holding state of the opening / closing cover portion 3 is released, the opening / closing cover portion 3 is automatically opened by the urging force of the torsion spring 35 (see FIG. 7) arranged on the other end side in the longitudinal direction thereof. It has become.

The thermal head 28 (see FIG. 8B) is a printing means for printing information such as characters, symbols, figures, and barcodes on the label PL, and the platen roller 10 is at the closing position of the opening / closing cover portion 3. The thermal head 28 is mounted on the head bracket 27 via the circuit board 36 with the printed surface of the thermal head 28 facing the paper route. On the printed surface of the thermal head 28, a plurality of heat generating resistors (heating elements) that generate heat when energized are installed side by side along the width direction of the label continuum P (short direction of the mount PM). The circuit board 36 is a wiring board that transmits a print signal to the thermal head 28.

The coil spring 29 (see FIG. 8) is a member that urges the head bracket 27 and the thermal head 28 toward the platen roller 10 when placed at the closed position of the opening / closing cover portion 3, and is a member on the back side of the head bracket 27 (of the circuit board 36). It is installed on the back side of the mounting surface). Since the head bracket 27 is pushed toward the platen roller 10 by the urging force of the coil spring 29, the platen shaft 10a fitted in the groove 27b of the head bracket 27 is also firmly pressed, and the opening / closing cover portion 3 is held by the head bracket 27. The state is maintained.

Here, as shown in FIG. 8B, the unit holding portion 3a of the opening / closing cover portion 3 is arranged in the gap between the eaves portion 4cp of the peeling unit 4 and the leaf spring 4da at the time of issuing the peeling, and comes into contact with the leaf spring 4da. The peeling unit 4 is pressed by pressing in this state. As a result, the peeling unit 4 is fixed at the peeling issuing position, and the peeling roller 4a of the peeling unit 4 is urged toward the platen roller 10. Therefore, the peeling roller 4a of the peeling unit 4 can be urged to the platen roller 10 in a firm and stable state at the time of issuing the peeling.

Next, continuous issuance and peeling issuance of the printer 1 will be described with reference to FIGS. 9A and 9B. 9 (a) is a schematic configuration diagram of the printer at the time of continuous printing of FIG. 1 (a), and FIG. 9 (b) is a schematic configuration diagram of the printer at the time of peeling printing of FIG. 1 (b).

In both continuous printing and peeling printing, the platen roller 10 is rotated with the label continuous body P unwound from the paper accommodating portion 6 sandwiched between the thermal head 28 and the platen roller 10. The label continuum P is conveyed by. At the time of this transfer, the printing timing is set based on the information detected by the sensor 12, and the heat generating resistor of the thermal head 28 is selectively generated by the printing signal transmitted to the thermal head 28 to generate heat for the label of the label continuum P. Print the desired information on the PL.

Here, in continuous issuing, as shown in FIG. 9A, the peeling unit 4 is arranged at the continuous issuing position inside the printer 1. The printed label PL is discharged without being peeled off from the mount PM. In the case of continuous issuance, a mount PM with the required number of label PLs can be created, and the label PL can be peeled off from the mount PM and pasted at the site. Therefore, the object to which the label PL is pasted is from the printer 1. Suitable for remote locations.

As shown in FIG. 9A, the peeling roller 4a is housed inside the main body case 2 at the continuous issuing position. As a result, the peeling roller 4a does not protrude from the main body case 2, making it difficult for the operator to touch the peeling roller 4a, and deterioration of the peeling roller 4a is prevented.

On the other hand, in peeling issuance, as shown in FIG. 9B, the peeling unit 4 is arranged at the peeling issuing position, and the mount PM is placed on the peeling roller 4a and the platen roller 10 of the peeling unit 4 via the peeling pin 11. Put it in the state of being sandwiched between. As a result, when the platen roller 10 is rotated for printing and the label continuum P is conveyed, the mount PM is conveyed while being sandwiched between the peeling roller 4a and the platen roller 10, while the label PL after printing is 1. Each sheet is peeled off from the mount PM and discharged to the outside of the machine. In the case of peeling issuance, the label PL is ejected one by one, so that it is suitable when the object to which the label PL is attached is near the operator.

In the printer 1 of the present embodiment, continuous issuance and peeling issuance can be switched, and one unit can handle two situations, that is, when the object to which the label PL is attached is close to the printer 1 and when it is far from the printer 1. It is easy to use and economical.

Next, the support 41 to which the release unit 4 is attached will be described with reference to FIGS. 10, 11 and 12. 10 is a perspective view showing the peeling unit and the support base at the continuous issuing position, FIG. 11 is a side view of the peeling unit and the support base of FIG. 10, and FIG. 12 is a first mounting piece of the support base of FIG. It is explanatory drawing which shows the relationship between the component element formed on the surface facing the 2nd mounting piece, and the peeling unit.

The support base 41 is provided in the opening 2a of the main body case 2, and has a pedestal portion 41a to which the peeling sensor 43, which is a light reflection type sensor for detecting the presence or absence of the label PL at the time of issuing the peeling, is attached. .. A pair of unit mounting portions 41b for mounting the peeling unit 4 are formed at both ends of the pedestal portion 41a in the width direction.

The unit mounting portion 41b is composed of a first mounting piece 41ba located outside the pedestal portion 41a in the width direction and a second mounting piece 41bb located inside and facing the first mounting piece 41ba. The support portion 4c of the peeling unit 4 is sandwiched between the first mounting piece 41ba and the second mounting piece 41bb with a slight gap formed.

A shaft 42 is attached to the unit attachment portion 41b so as to straddle the first attachment piece 41ba and the second attachment piece 41bb. The shaft 42 is inserted into a guide rail hole 4ch formed in the support portion 4c sandwiched between the first mounting piece 41ba and the second mounting piece 41bb. That is, the guide rail hole 4ch is engaged with the shaft 42.

Therefore, the peeling unit 4 can slide and move along the shaft 42 by moving the guide rail hole 4ch along the shaft 42, and can swing with the shaft 42 as a fulcrum.

Further, as shown in FIGS. 10 and 11, a coil spring 44 is attached between the peeling unit 4 and the support base 41. One end of the coil spring 44 is fixed to a mounting protrusion 41bc formed at one end of the first mounting piece 41ba of the unit mounting portion 41b, and the coil spring 44 is curved in a substantially L shape from there to the side surface of the first mounting piece 41ba. It is attached to a mounting projection 4ci that is curved and extends along the formed guide eaves 41bd and whose other end is formed on the other end side of the support portion 4c in the longitudinal direction (the side opposite to the mounting position of the peeling roller 4a in the longitudinal direction). Has been done. Further, the shaft 42, which is the swing shaft described above, is located on the side where a line segment connecting both ends of the coil spring 44 is drawn with respect to the coil spring 44 curved in this way. The reason why the coil spring 44 is curved by the guide eaves 41bd is to obtain the necessary tensile force without taking up space.

With such a structure, the peeling unit 4 is provided with an urging force in the direction in which the mounting protrusion 4ci side of the guide rail hole 4ch abuts on the shaft 42 (in the direction opposite to the continuous issuing position) by the coil spring 44. The urging force is applied to swing in the direction away from the thermal head 28 (first direction) with the mounting projection 4ci side of the guide rail hole 4ch in contact with the shaft 42 as a fulcrum. That is, the coil spring 44 gives the peeling unit 4 two urging forces, one that slides and one that swings in the first direction.

As a result, when the holding state held at the continuous issuing position is released by the release lever portion 19, the peeling unit 4 moves (slides) to the side opposite to the continuous issuing position due to the urging force of the coil spring 44 and guide rail. One end of the hole 4ch comes into contact with the shaft 42 (slide movement position), and swings to a predetermined swing end in the first direction with the shaft 42 as a fulcrum (swing end position).

Here, as shown in FIG. 12, in the support portion 4c of the peeling unit 4, the first claw portion 4cj located on one side of the guide rail hole 4ch in the short direction is located on the other side and the second Claw portions 4ck are formed respectively. Further, a first protruding portion 41be and a second protruding portion 41bf are formed on the surface of the first mounting piece 41ba facing the second mounting piece 41bb.

Then, when the peeling unit 4 slides along the shaft 42 from the continuous issuing position to the opposite side to the first protruding portion 41be, the first claw portion 4cj slides and the peeling unit 4 moves. A guide surface 45 for guiding the direction is formed. Further, as described above, when the peeling unit 4 swings in the first direction with the shaft 42 as a fulcrum, the first claw portion 4cj comes into contact with the first protruding portion 41be to define the swing end position. The first stopper 46 is formed. Further, the first protruding portion 41be has a first claw when the peeling unit 4 swings from the swinging end position in a second direction opposite to the first direction to move to the peeling issuing position. A regulating surface 47 is formed to prevent the peeling unit 4 from sliding and returning to the continuous issuing position.

The swinging end position of the peeling unit 4 in which the first claw portion 4cj is in contact with the first stopper 46 is opened and closed on one end side (tip side) facing the opening / closing cover portion 3 of the peeling unit 4. It is a position existing in the swing locus of the cover portion 3.

On the other hand, when the peeling unit 4 reaches the peeling issuing position, the second claw portion 4ck comes into contact with the second protruding portion 41bf to prevent the peeling unit 4 from returning to the continuous issuing position. The stopper 48 of 2 is formed.

Next, the setting of the continuous issuing position and the peeling issuing position in the peeling unit 4 of the printer 1 of the present embodiment will be described with reference to FIGS. 13 to 18 and FIG. 12 described above. 13 to 15 are schematic configuration diagrams of the main parts of the printer showing the state of the peeling unit and the open / close cover portion when the peeling unit is set to the peeling issuing position, and FIGS. 16 to 18 show the peeling unit at the peeling issuing position. It is explanatory drawing which shows the relationship between the peeling unit and a support base at the time of setting.

FIG. 14A shows a stage before setting the peeling unit 4 when the peeling unit 4 is set to the peeling issuing position. The peeling unit 4 in the pre-setting stage is arranged so as to project diagonally with respect to the upper surface (the surface on which the issuing port is arranged) of the printer 1.
