Here, the blade 11 has a pin 12 projecting from the front surface thereof, and the pin 12 is engaged with an elongated hole 13 formed at the left end of the arm 8. Further, in the cutter device 1, a detection sensor 14 composed of a micro switch is attached to a lower left portion of the cutter frame 2;
The detection terminal of the detection sensor 14 comes into contact with the distal end of the arm 8 so as to freely contact and separate therefrom.

[0004] The cutter device 1 having the above-described structure is used.
As shown in FIG. 4, for example, the slit 10 is mounted in a main body housing 16 of a ticket printer or the like such that the slit 10 is positioned on the paper transport path 15 and is used for cutting the continuous paper 17 as a medium. You.

In such a configuration, in the cutter device 1, the continuous paper 17 set on the paper transport path 15 of the main body housing 16 is inserted into the slit 10 of the cutter frame 2.
Is inserted through.

Therefore, in the cutter apparatus 1, the blade 11 is normally stopped at a home position where the blade 11 does not descend and intersect with the slit 10. In this state, the tip of the arm 8 is detected by the detection sensor 14. Therefore, when the cutter device 1 cuts the continuous paper 17, when the last gear 6 of the gear train 5 connected to the drive shaft 4 of the drive motor 3 rotates, the arm 8 connected to the pin 7 of the last gear 6
Is rotated upward, and the blade 11 connected to the distal end of the arm 8 moves up to the cut position intersecting the slit 10, so that the continuous paper 17 inserted in the slit 10 Will be disconnected.

After the cutting operation is completed, the driving of the driving motor 3 is continued, and when the blade 11 is lowered to the home position and the arm 8 is detected by the detection sensor 14, the driving of the driving motor 3 is stopped. Is done.

However, in the cutter device 1 as described above,
For example, the blade 11 may bite the continuous paper 17 while moving from the home position to the cut position. When such a jam occurs, the operation of the drive motor 3 and the like also stops. In such a case, for example, the jam processing can be performed by forcibly lowering the blade 11 toward the home position, but for this purpose, it is necessary to reversely rotate the drive motor 3. But,
This is not practical because it is necessary to provide a drive circuit and a switching gear for freely rotating the drive motor 3 reversely. For this reason, in such a cutter apparatus 1, when the above-described jam occurs, the apparatus is disassembled to perform a jam clearing operation, which is difficult and unfavorable for general users.

Means for solving such problems include:
The gear train 5 is provided with a manual operation unit (not shown), and when a jam occurs, the gear train 5 is manually operated to operate the blade 11.
Can be forcibly lowered. However, in this case, there is a concern that the user drives the manual operation unit in the reverse direction. In this case, the blade 11 rises toward the cut position, so that the continuous paper 17 bites, and
The blade 11 and the gear train 5 will be damaged.

[0011]

According to a cutter apparatus, a blade is connected to a drive source via a power transmission mechanism, and the blade is moved from a home position to a cut position by driving the drive source to cut the medium. , A manual operation unit is connected to the power transmission mechanism, and the manual operation unit is connected to the manual operation unit .
Normally for driving force acting from outside the body housing
A one-way clutch is provided for connecting the manual operation unit and the power transmission mechanism in a direction in which the blade moves in the opposite direction from the cut position to the home position.

[0012]

Even if a jam occurs in which the blade that moves from the home position to the cut position to cut the medium bites the medium, the blade can be operated via the connected one-way clutch by operating the manual operation unit. Since it is possible to return from the cut position to the home position, even a general user can easily carry out the jam processing without disassembling the apparatus, and furthermore,
Even if the manual operation unit is operated in the opposite direction to the designated direction, the connection state of the one-way clutch is released and the blade is not driven, so that damage to the blade and the power transmission mechanism due to erroneous operation is also prevented.
