When rewinding, the control unit controls the platen roller 8a for the number of lines from the cutter 9 position to the standby position.
Then, the feed roller pair 11 is rotated in the opposite direction, and the recording sheet 4 is
The tip is wound back to a predetermined standby position.

Next, when the received image is 84 size, the sheet width detection sensor 16b detects that the recording sheet 5 is 84 size, and a signal from the CPU is sent to the motor 1.
7b and 17c are driven to rotate the feed roller pair 14 and the platen roller 8a, and predetermined recording is performed in the same manner as described above.

As mentioned above, the recording sheet 4 or 5 can be easily set and manually cut by pressing the manual cut switch 22 or 23, and also when conveyed, the feed roller pair 11.14 is driven by a single drive motor.
Also, unlike when driving the platen roller 8a, there is no need to use a solenoid or the like to change the direction of drive transmission, so rotational errors such as backlash are extremely reduced, making it possible to accurately control the conveyance 1 of the recording sheet. It becomes possible.
