When the cutter 16 is in the non-actuated state, the detection portion 51a is engaged with the cam groove 52a of the cam roller 52 to be in the OFF state, and the cam roller 52 rotates from this state. The detection unit 51a is pushed into an ON state, and the stepping motor 20 is controlled by a controller based on the detection signal. Reference numeral 53 is a link pin protruding from the driven gear for cutter 40a, which is connected to a link (not shown) interlocking with the cutter 16.

The operation will be described based on the above configuration. In the reception mode, as shown in FIG. 4, by engaging the first locking member 44 with the first engaging portion 46, the first planetary gear 30 is moved to the driven gear 38a for the document conveying roller and the cutter. It suffices to lock the intermediate gear 40b in a neutral position where it does not mesh with the intermediate gear 40b and drive the stepping motor 20 in the reverse direction to rotate the drive gear 27 in the counterclockwise direction B. As a result, the sun gear 28 rotates clockwise C, the second planetary gear 31 revolves clockwise C and meshes with the driven gear 39 for the platen roller, and the second planetary gear 31 counterclockwise. The driven gear 39 for the platen roller is rotated in the clockwise direction C to rotate to B, and the platen roller 12 is rotated in synchronization with this, and the recording paper P is sent out. Received information is recorded (see FIG. 9).

Just rotate it. As a result, the sun gear 28 rotates in the clock direction C, the first and second planetary gears 30 and 31 revolve in the clockwise direction C, and the first planetary gear 30 meshes with the driven gear 38a for the original conveying rollers. Then, the second planetary gear 31 meshes with the driven gear 39 for the platen roller, and the reception mode and the transmission mode described above are entered, and the document G is transported by the document transport roller 5, and the document G is written on the document G by the reading head 7. The read information is read, the platen roller 12 is rotated and the recording paper P is sent out, and the read information is recorded on the recording paper P by the recording head 11 (see FIG. 9).

In the case of the cutter forward rotation mode, as shown in FIG. 7, the lock device 24 is unlocked, and the stepping motor 20 is normally driven to rotate the drive gear 27 in the clockwise direction C. . As a result, the sun gear 28 rotates counterclockwise B, the first planetary gear 30 revolves counterclockwise B and meshes with the cutter intermediate gear 40b, and the first planetary gear 30 clockwise C. And rotates the driven gear 40a for the cutter in the clockwise direction C through the intermediate gear 40b for the cutter, and the support shaft 15 for the cutter 16 is rotated in synchronization with this, and the recording paper P is cut by the cutter 16. This can be done (see Fig. 9). In this case, the second planetary gear 31 also revolves in the counterclockwise direction B, but since the third engaging portion 48 engages with the second lock member 45, this second planetary gear 31 is used for the document conveying rollers. It does not mesh with the intermediate gear 38b.

In the cutter reverse rotation mode, as shown in FIG. 8, the solenoid 49 is operated to engage the first lock member 44 with the second engagement portion 47, and the stepping motor 20 is driven in reverse. The drive gear 27 may be rotated in the counterclockwise direction B. As a result, the sun gear 28 rotates clockwise C, the first planetary gear 30 rotates counterclockwise B, and the cutter driven gear 40a rotates counterclockwise B via the cutter intermediate gear 40b. Then, the support shaft 15 for the cutter 16 is rotated in conjunction therewith, and the cutter 16 can be reversed to return it to its original position. As a result, the cutter 16 bites the recording paper P and a so-called cutter jam occurs. Even if it does, the cutter jam condition can be automatically cleared. In this case, the first and second planetary gears 30 and 31 try to revolve in the clockwise direction C, but the first planetary gear 30 is formed by the first locking member 44 engaging the second engaging portion 47. , Its revolution is blocked, the meshing state with the cutter intermediate gear 40b is maintained, and the second planetary gear 31 is engaged with the platen roller by engaging the fourth and fifth engaging portions 35a, 36a with each other. It is prevented from meshing with the driven gear 39.
