ABSTRACT:
A device for driving a platen includes a motor for driving the platen, and a power transmission mechanism for transmitting the power of the motor to the platen. The power transmission mechanism includes a drive wheel having a pin and driven by the motor for rotation, and a driven wheel having a plurality of grooves in which the pin of the drive wheel is engageable. With this construction, the platen can be rotated and stopped.
