As the thermal paper, there are various types such as a thermal coloring type having a coloring layer that develops color by heating of the thermal head 8, and a thermal punching type in which a perforated layer to be perforated by heating is laminated on a base material layer. Can be used.
[0018]
A pickup roller 11 and a separation block 12 are disposed on the side close to the printing mechanism unit 7 in the paper storage unit 6 (see FIGS. 5A and 5B). The paper cassette 5 accommodated in the paper accommodating portion 6 is attached to the bottom plate 6A of the paper accommodating portion 6 via a biasing means 15 such as a leaf spring provided on the inner surface of the closed lid body 13. Be forced. Of the stacked sheets 4 in the sheet cassette 5, the sheet 4 (lowermost sheet) exposed outside the sheet cassette 5 is abutted against the upper surface of the pickup roller 11. Only the lowermost sheet 4 passes through the gap between the lower end of the separation block 12 and the guide plate 17 by the cooperation of the rotational drive of the pickup roller 11 and the guide locking surface 121 of the separation block 12. A platen roller 9 is rotatably provided adjacent to the separation block 12, and a paper guide 10 is urged by an urging means 16 such as a pressing coil spring on the outer peripheral surface thereof. The sheet 4 separated and conveyed from the sheet cassette 5 by the pickup roller 11 and the guide locking surface 121 is conveyed between the platen roller 9 and the paper guide 10. The paper guide 10 is formed on a slidable contact surface 10 </ b> A having a concave curved shape such as a substantially U-shaped sideways cross section so that the cross section thereof is along the outer peripheral surface of the platen roller 9. A guide film 21 is provided on the upper surface of the paper guide 10 on the thermal head 8 side. The guide film 21 prevents the sheet 4 from being lifted with respect to the platen roller 9 between the paper guide 10 and the platen roller 9 by pressing the sheet 4 against the peripheral surface of the platen roller 9 by the tip portion.
[0019]
The paper guide 10, the guide film 21, and the thermal head 8 that is disposed above the paper guide 10 and is pivotable about the pivoting support P, and that can contact and separate from the printing position on the upper surface of the platen roller 9. Due to the lower surface, the paper 4 separated and conveyed from the paper container 6 is reversed and conveyed in a horizontal U-shape and conveyed to the printing position of the platen roller 9.

The drive mechanism for the platen roller 9 and the pick-up roller 11 includes a drive motor 22 and gears arranged on one inner side surface (in the embodiment, the right side in the conveyance direction of the paper 4 shown in FIG. 2) along the long side of the main body case 2. And a transmission mechanism (gear train) 23. The diameter of the platen roller 9 is larger than the diameter of the pickup roller 11, and the paper conveyance speed at the platen roller 9 is set to be larger than the paper conveyance speed at the pickup roller 11. The sheet separation is performed slowly, and the sheet is conveyed by the platen roller 9 and consequently the printing speed is increased. For this purpose, a one-way clutch (not shown) is provided downstream of the platen roller 9 in the gear train so that the pickup roller 11 can be rotated for high-speed conveyance at nine platen rollers.
[0021]
Next, the release interlocking mechanism (the simultaneous pressing and simultaneous pressing releasing mechanism of the paper guide 10 and the thermal head 8 with respect to the outer periphery of the platen roller 9) will be described. This release interlocking mechanism is for easily removing the paper 4 when a paper jam occurs in the outer peripheral portion of the platen roller 9.
[0022]
Next, details of each component in the release interlocking mechanism will be described with reference to FIGS. 5 (a), 7 and 8 (a) to 8 (c). The components of the release interlocking mechanism are arranged in the main body case 2 so as to be reciprocally movable, and the paper guide 10 and the thermal head 8 are separated from the platen roller 9 against the urging force of the urging means 16, 19. An actuating means 18 that can be switched between a separating position to be urged and an urging position for urging the paper guide 10 and the thermal head 8 against the platen roller 9 by the urging force of the urging means 16, 19. The actuating means 18 includes an interlocking link body 133 having a first cam 36 and a second cam 37 as cam means to be described later, and an actuating member 28 as an actuated portion for switching and moving the cam means.
[0023]
A long guide support block 24 is fixed to the inner surface along the pair of long sides of the main body case 2 in the direction in which the platen roller 9 is disposed from the paper guide 10. The guide support block 24, the actuating member 28, which will be described later, and the interlocking link body 133 are formed of a synthetic resin material symmetrically. FIG. 7 shows a perspective view of parts such as the right guide support block 24. is there.
[0024]
An inwardly open longitudinal guide through which a locking piece 25 projecting downward from the left and right sides of the free end side of the lid 13 can be inserted vertically in the middle of the inner side surface of each guide support block 24. A groove 26 is formed. Further, a lateral guide groove 27 along the longitudinal direction is formed in the middle of the vertical direction on the outer side surface of each guide support block 24, and an operating member 28 is provided in the lateral guide groove 27 in the front-rear direction (guide). It is movably fitted in the longitudinal direction of the support block 24.
[0025]
A pair of front and rear restricting blocks 29 and 30 project laterally from the outer side of each actuating member 28 at a position near one end in the moving direction with a gap between the longitudinal guide grooves 26, and the inner surface of the guide support block 24. A pair of restricting blocks 29 and 30 face the side, and a punching window 31 is formed so as to be movable in the front-rear direction by a predetermined distance.
[0026]
Further, a base portion 32B of the resin spring body 32 in which the upward leading end portion 32A is fitted in the vertical guide groove 26 is fitted into an engagement portion 33 formed in a recess on the outer surface of the guide support block 24, and the base portion of the resin spring body 32 is inserted. A continuous portion 32 </ b> C between 32 </ b> B and the upward leading end portion 32 </ b> A is located below the guide support block 24. In a state where the lid body 13 is rotated upward in the retracted position and is pulled 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 in the operating member 28 is provided. Since the vertical guide groove 26 is positioned between the upper and lower guide grooves 29 and 30, the upward tip 32A of the resin spring body 32 protrudes upward between the pair of restricting blocks 29 and 30, and the operation member 28 moves in the front-rear direction. Can be regulated. Accordingly, the upward distal end portion 32A of the resin spring body 32 is fitted between the pair of restricting blocks 29, 30 so that the release interlocking mechanism does not move forward inadvertently at the opening position of the lid body 13. The lock means can be held in a locked state.
[0027]
On the other hand, an inclined surface 30 </ b> A is formed on the lower surface side of the one (rear) regulating block 30, which becomes an upper position as it goes rearward. Therefore, in the state in which the operating member 28 is moved forward (the state in which the restriction block 30 has moved to the position of the longitudinal guide groove 26, which is referred to as the closing position of the lid 13), the upward tip portion on the inclined surface 30A. 32A abuts to hold the actuating member 28 in the forward movement direction, and this configuration provides a locking means for holding the release interlocking mechanism in a locked position so as not to inadvertently retract.
[0028]
On the front end side of the operating member 28, an interlocking link body 133 that is rotatably fitted to the rotation shaft 9 </ b> A of the platen roller 9 is rotatably connected via a pin 34 and a vertically long hole 35. Yes. A longitudinally long hole 35 may be formed in the interlocking link body 133, and a pin 34 may be formed in the operating member 28.
[0029]
The interlock link body 133 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 133, when the first cam body 36 contacts and separates from the appropriate front surface of the paper guide 10, the second cam body 37 contacts and separates from the appropriate lower surface of the thermal head 8 at the same time. Has been.
[0030]
With this configuration, as shown in FIG. 5B, the lid 13 is opened, and the opened paper cassette 5 is set in the paper accommodating portion 6 of the main body case 2 with the surface of the paper 4 facing downward. When the body 13 is rotated downward, the sheet cassette 5 is pressed downward by the leaf spring biasing means 15 (see FIG. 5A) on the lower surface of the lid 13, so that the lowermost surface of the stacked sheets 4 The tip side is pressed onto the pickup roller 11.
[0031]
And interlocked with the operation to prevent the lid 13 from being opened carelessly (the lid 13 is turned downward and moved forward in parallel with the opening surface of the main body case 2 to the state shown in FIG. 5A). As described below, the paper guide 10 and the guide film 21 attached to the paper guide 10 are pressed against the outer peripheral surface of the platen roller 9 and the thermal head 8 is also pressed. That is, on both the left and right sides of the lid 13, lock pieces 25 as engaging portions that can be engaged to switch the operating member 28 between the separation position and the biasing position are formed in the vertical guide groove 26 of the guide support block 24. It is provided to fit downward from above. When the lock piece 25 enters the position shown in FIG. 8B, that is, between the pair of regulating blocks 29 and 30 of the operating member 28, the upward tip 32 A of the resin spring body 32 is vertically moved by the lock piece 25. Pushed by the lower retraction area of the guide groove 26, the movement of the actuating member 28 in the forward direction (the direction of FIGS. 5B and 8A) is allowed. In this state (position where the lid 13 can be opened), when the lid 13 is moved toward (moved forward) in the direction of the fixed cover 3, the lock piece 25 pushes the actuating member 28 forward via the front restriction block 29. . By this operation, the lock piece 25 moves forward from the vertical guide groove 26 and comes to a position near the front of the extraction window 31 in the guide support block 24. Therefore, the lock piece 25 cannot move upward, and the lid 13 cannot be opened and rotated. (See FIG. 8 (a)). That is, the lid 13 is in the closed position. At the forward position of the actuating member 28 (closed position of the lid 13), the upward tip 32A of the resin spring body 32 comes into contact with the inclined surface 30A of the lower surface of the rear regulating block 30, and this resin spring body. The urging force of 32 can prevent the actuating member 28 from retreating carelessly.
[0032]
In the closed state (closed position) of the lid 13 (when the pivot fulcrum of the lid 13 is in the locked position in the state of FIGS. 5A and 8A), Since the restricting block 29 is pushed, the actuating member 28 moves forward, and the interlocking link body 133 connected thereto is rotated clockwise as shown in FIG. Then, since the first cam body 36 provided in the interlocking link body 133 rotates in a direction away from the front surface of the paper guide 10, the paper guide 10 is moved by the urging force of the urging means 16 on the back surface side. 9 is urged and moved in the direction of contact with the outer peripheral surface. At the same time, the second cam body 37 provided on the interlocking link body 133 rotates in a direction away from the lower surface of the thermal head 8. As a result, the heating element 8 </ b> A of the thermal head 8 is pressed against the upper surface of the platen roller 9 by the biasing force of the biasing means 19. This state is defined as an urging position. For this reason, the 1st cam body 36, the interlocking link body 133, and the operation member 28 are locked in the state of Fig.8 (a).
[0033]
When a print command and image data (print data) are sent from a personal computer (not shown) to the portable small-sized printer device 1 via a USB terminal or an infrared terminal, the drive motor 22 (see FIG. 6) is driven to rotate, and the pickup roller 11 and the platen roller 9 begin to rotate simultaneously. Due to the rotation of the pickup roller 11, the leading edge 41 of the lowermost sheet 4 of the stacked sheets 4 (see FIG. 3) collides with the separation block 12 and only the lowermost sheet 4 is separated, and the separation block It is conveyed between the lower surface of 12 and the guide plate 17. Next, the sheet 4 sandwiched between the platen roller 9 and the paper guide 10 is nipped and conveyed by the rotating platen roller 9 and the paper guide 10 and moves in the direction of the thermal head 8. Further, the paper 4 is pressed against the platen roller 9 by the leading end portion of the guide film 21 so that the paper 4 does not float with respect to the platen roller 9 between the paper guide 10 and the thermal head 8. After printing on the surface of the paper 4, the paper can be discharged out of the portable small-sized printer device 1 through the paper discharge port 20 in the gap between the solid cover 3 and the back of the separation block 12.
[0034]
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 interlocked with the opening operation of the lid 13. First, when opening the lid 13, the lid 13 parallel to the upper surface of the main body case 2 is horizontally moved (retracted) away from the fixed cover 3, and the pivot fulcrum of the lid 13 is moved to the unlocking position. Let
[0035]
As shown in FIG. 8A to FIG. 8B, 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 paired with a pair of front and rear regulating blocks 29, The operating member 28 is forcibly retracted against the urging force of the urging means 16, 19 because it is fitted between 30. 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.
[0036]
At the retracted position of the actuating member 28, the upward tip 32A of the resin spring body 32 retracted in the downward retracted region of the vertical guide groove 26 is engaged between the pair of restriction blocks 29 and 30 from below by the elastic force, The retracted position of the actuating member 28 can be maintained (see FIG. 8C). Further, the paper cassette 5 can be exchanged by rotating the lid 13 upward.
[0037]
As the actuating member 28 moves backward, the interlocking link body 133 connected to the actuating member 28 via the pin 34 and the vertically long hole 35 is rotated around the axis 9A of the platen roller 9 in FIG. Turn counterclockwise. The first cam body 36 provided on the interlocking link body 133 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 up the lower surface of the thermal head 8 against the urging force of the urging means 19, and the heating element 8A of the thermal head 8 is separated from the outer peripheral surface of the platen roller 9 (FIG. 8 (b)). This state is a separated position. Thereby, the paper 4 wound around the outer periphery of the platen roller 9 can be pulled out of the portable small printer 1 with a light force. Since the thermal head 8, the paper guide 10, and the guide film 21 can be brought into contact with and separated from the platen roller 9 with a single touch, the operability is excellent.
[0038]
Here, the operating member 28 is locked at the retracted position by the resin spring body 32 so as not to move, but the resin spring body 32 can be deleted. Resin spring body 32, first and second cam bodies 36 and 37, and biasing means 16 and 19 correspond to the lock means for holding the release interlocking mechanism in the locked state between the open position and the closed position of lid 13. However, it is also possible to change the lock means so that the lock body 13 is held in the locked state either when the lid 13 is in the open position or when it is in the closed position.
[0039]
The both ends of the support shaft 11A of the pickup roller 11 are rotatably supported in the shaft holes 24A (see FIG. 7) of the left and right guide support blocks 24, so that the number of parts can be eliminated. . Further, although not shown, the leading edge of the conveyed paper 4 is detected at a substantially central portion in the longitudinal direction of the paper guide 10 (corresponding to a substantially central portion in the width direction orthogonal to the conveying direction of the paper 4). By providing the optical sensor for detecting the paper, the paper 4 separated from the paper cassette 5 by the pickup roller 11 is sensed as being fed to the paper guide 10 in a skewed state, and a paper jam occurs. It is desirable to prevent this from happening.
[0040]
In the above, as a modification of the locking means for holding the operating member 28 and thus the release interlocking mechanism in a state where the lid member 13 is not inadvertently retracted when the lid body 13 is closed, the first cam body 36 is moved from the contact surface of the paper guide 10. When leaving, the first cam body 36 rotates so as to exceed the action line connecting the contact position between the platen roller 9 and the paper guide 10 and the axis of the shaft 9A of the platen roller 9, so that the so-called fulcrum is exceeded. What is necessary is just to comprise so that the position which the operation member 28 advanced can be hold | maintained.
[0041]
As a locking means for holding the release interlocking mechanism in a locked state at both the opening position and the closing position of the lid body 13, a pair of restriction blocks 29 and 30 in the operating member 28 and a resin spring body 32 are provided. Fitting and rotation of a range between the contact position and the separation position of the first cam body 36 with respect to the paper guide 10 and means for pressing the upward tip 32A of the resin spring body 32 against the inclined surface 30A of the restriction block 30 at the rear position. There is movement. Moreover, what is necessary is just to employ | adopt any one of the said structures as a locking means only in any one of the opening position of the cover body 13, or a closing position. Since the release interlocking mechanism and the locking means are formed in association with the operating member 28 and the interlocking link body 133, the structure can be made extremely compact.
[0042]
The release mechanism is not limited to the above embodiment, and various modifications can be made without departing from the spirit of the release mechanism.
For example, FIG. 9 is a cross-sectional view showing another embodiment of the release interlocking mechanism. In this regard, an operation lever 40 such as a side view T-type as an example of a rotation member is configured to rotate around a horizontal rotation support shaft 41 at a lower portion thereof.
