Then, as shown in FIG. 7, a vertical guide groove 26 is formed in the middle of the longitudinal direction of each guide support block 24 so as to vertically penetrate and open toward the center of the main body case 2. A cutout window 31 is formed which is orthogonal to the groove 26 and communicates in the horizontal direction. The upper wall portion 241 of the removal window 31 of the guide support block 24 prevents the lock piece 25 as the intruding portion from coming out upward when the lid 13 is moved in the closing direction in parallel with the opening surface of the main body case 2. It functions as the first restricting means.

Guide support blocks 24, 24, which are long in the direction in which the platen roller 9 is arranged from the paper guide 10, are formed on the inner surface of the body case 2 along the pair of long sides.
To fix. The guide support blocks 24, 24 and an actuating member 28 described later are symmetrically formed of a synthetic resin material (see FIG. 2). FIG. 7 is a perspective view of parts such as the right guide support block 24. It is a figure.

A lock piece 25 as an intruding portion projecting downward from both left and right sides of the free end side of the lid 13 can be vertically inserted through a middle portion of the inner surface of each guide support block 24 in the longitudinal direction. An inwardly-opening vertical guide groove 26 is formed. On the outer surface side of each of the guide support blocks 24, a lateral guide groove 27 is formed in the middle of the vertical direction along the longitudinal direction, and an operating member 28 is formed in the lateral guide groove 27 in the front-back direction (guide It is movably fitted in the longitudinal direction of the support block 24.

A pair of front and rear restriction blocks 29, 30 are laterally projected at the outer surface of each actuating member 28 at a position near one end in the direction of movement thereof, with the spacing of the vertical guide groove 26 being provided therebetween. On the inner surface of the block 24, a pair of restriction blocks 29, 30 is provided sideways, and a punching window 31 is formed so as to be movable in the front-rear direction by a predetermined distance.

Further, the base portion 32b of the resin spring body 32 whose upper end portion 32a fits in the vertical guide groove 26 is fitted in the engaging portion 33 formed in the outer surface of the guide support block 24 to form a resin spring body. The base 32b of 32 and the connecting portion 32c of the upward end 32a are located below the guide support block 24. In addition, in a state where the lid body 13 is rotated upward at the retracted position and comes out of the vertical guide groove 26 of the guide support block 24 (this is referred to as an open position of the lid body 13),
A pair of restriction blocks 29, 3 in the operating member 28.
Since the vertical guide groove 26 is positioned between 0, the upward end portion 32a of the resin spring body 32 is located at the pair of the regulation blocks
It is possible to regulate the movement of the operating member 28 in the front-rear direction by projecting upward between 9 and 30. Therefore, this resin spring body 32
The upward tip end 32a is the pair of regulation blocks 29,
By fitting between the lock members 30, the locking mechanism can be held in the locked state so that the release interlocking mechanism does not inadvertently move forward at the open position of the lid 13.

On the other hand, the one (rear side) regulation block 3
On the lower surface side of 0, an inclined surface 30a is formed which becomes an upper position toward the rear. Therefore, when the actuating member 28 is moved forward (the restriction block 30 is moved to the position of the vertical guide groove 26, which is referred to as the closed position of the lid 13), the upward tip portion 32a is attached to the inclined surface 30a.
Contact with each other to hold the actuating member 28 in the forward movement position, and with this structure, the release interlocking mechanism serves as a locking means for holding the release interlocking mechanism in the locked position so as not to retract inadvertently.

On the front end side of the actuating member 28, an interlocking link body 33 that is rotatably fitted on the rotary shaft 9a of the platen roller 9 is rotatable via a pin 34 and a vertically elongated hole 35. It is connected. Vertical hole 3 in interlocking link body 33

The interlocking link body 33 is integrally formed with a first cam body 36 and a second cam body 37 as cam means. According to the rotation of the interlocking link body 33, when the first cam body 36 comes into contact with and separates from the front surface of the paper guide 10, the second cam body 37 comes into contact with and separates from the lower surface of the thermal head 8 at the same time. Has been done.

With this structure, as shown in FIG. 5B, after the lid 13 is opened and the opened paper package 5 is set in the paper accommodating portion 6 of the main body case 2 with the paper 4 surface facing downward. When the lid 13 is rotated downward, the leaf spring urging means 15 (see FIG. 5A) on the lower surface of the lid 13 presses the paper package 5 downward.
The tip side of the lowermost surface of the stacked sheets 4 is pressed onto the pickup roller 11.

Then, an operation for preventing the lid 13 from being opened carelessly (the lid 13 is rotated downward to move forward in a state parallel to the opening surface of the main body case 2 to the state of FIG. 5A). ), The paper guide 10 is pressed against the outer peripheral surface of the platen roller 9 and the thermal head 8 is also pressed. That is, lock pieces 25, 25 as action portions that can be engaged to switch the operating member 28 between the separated position and the biased position are provided on the left and right sides of the lid body 13 in the vertical direction of the guide support blocks 24, 24. The guide grooves 26, 26 are provided so as to fit downward from above. The position shown in FIG. 8B, that is, the operating member 28.

The biasing force for locking the lid 13 at the closed position is mainly the biasing force of the biasing means 16 and 19, but the biasing force of the resin spring body 32 is also slightly acting. . The biasing force for locking the closed position may be the biasing force of at least one of the biasing means 16 and 19, and the resin spring body 32.

Then, from a personal computer (not shown) or the like, a USB
When the print command and the image data (print data) are sent to the printer device 1 via the terminal or the infrared terminal, the drive motor 22
Is driven to rotate, and the pickup roller 11 and the platen roller 9 start to rotate at the same time. By the rotation of the pickup roller 11, the leading edge 41 of the lowermost sheet 4 of the stacked sheets 4 collides with the separation block 12 and only the lowermost sheet 4 is separated, and the lower surface of the separation block 12 and the guides. It is conveyed to the board 17. Next, the platen roller 9
The paper 4 nipped between the paper guide 10 and the paper guide 10 is nipped and conveyed by the rotating platen roller 9 and the paper guide 10 and moved toward the thermal head 8 to be printed on the surface of the paper 4 and then fixed on the fixed cover. Paper can be discharged to the outside of the printer device 1 through the gap 20 between the body 3 and the back surface of the separation block 12.

Next, the operation of releasing the thermal head 8 and the paper guide 10 in conjunction with each other when a paper jam occurs will be described with reference to FIGS. 8 (a) to 8 (c). In the present embodiment, it is linked to the opening operation of the lid 13. First, when the lid body 13 is opened, the lid body 13 parallel to the upper surface of the main body case 2 is horizontally moved (retracted) in a direction away from the fixed cover body 3 to remove the lid body 1.
The rotation fulcrum of 3 is moved to the lock release position.

As shown in FIGS. 8 (a) to 8 (b),
When the lid body 13 is retracted, the lock pieces 25, 25 on both the left and right sides of the lid body 13 are fitted between the pair of front and rear regulation blocks 29, 30 of each operating member 28, so that the operating member 2
8 is forcibly retracted against the urging force of the urging means 16 and 19. At this time, the resin spring body 32 is moved against the urging force, but the urging forces of the urging means 16 and 19 are larger.

In the retracted position of the operating member 28, the vertical guide groove 2
6, the upward end portion 32a of the resin spring body 32 retracted to the lower retreat region of 6 is elastically forced to move the pair of regulation blocks 2
It is possible to engage between 9 and 30 from below and hold the retracted position of the actuating member 28 (see FIG. 8C). Also,
The paper package 5 can be replaced by rotating the lid 13 upward.

With the backward movement of the operating member 28, the interlocking link body 33 connected to the operating member 28 via the pin 34 and the vertically elongated hole 35 is arranged around the shaft 9a of the platen roller 9 in FIG. Rotate counterclockwise in b).
The first cam body 36 provided on the interlocking link body 33 pushes the front surface of the paper guide 10 against the urging force of the urging means 16 and separates it from the outer peripheral surface of the platen roller 9. At the same time, the second cam body 37 pushes the lower surface of the thermal head 8 upward against the urging force of the urging means 19, and the heating element portion 8a of the thermal head 8 separates from the outer peripheral surface of the platen roller 9 (FIG. 8 (b)). This state is the separated position. As a result, the paper 4 wound around the outer periphery of the platen roller 9 can be pulled out of the platen device 1 with a light force. Since the thermal head 8 and the paper guide 10 can be brought into contact with and separated from the platen roller 9 with one touch, the operability is excellent.

The both ends of the support shaft 11a of the pickup roller 11 are connected to the guide support blocks 2 on the left and right sides.
It is possible to reduce the number of parts by rotatably supporting the shaft holes 24a of 4 and 24. Although not shown, the leading edge of the conveyed paper 4 is detected at the substantially central portion in the longitudinal direction of the paper guide 10 (corresponding to the substantially central portion in the width direction orthogonal to the conveying direction of the sheet 4). By providing an optical sensor for detecting, it is detected that the sheet 4 separated and conveyed by the pickup roller 11 from the sheet package 5 has been conveyed to the position of the paper guide 10 in a skewed state, and a paper jam occurs. It is desirable to be able to prevent this.

As another embodiment, when not interlocking with the release interlocking mechanism, a pair of lock pieces 25, 25 as intruding portions provided on the left and right sides of the lid 13 and the left and right sides of the sheet accommodating section 6 are provided.
