ABSTRACT:
A paper feeding mechanism having a platen is driven by power from a drive source and clamps a recording paper sheet with paper holding rollers and pinch rollers so as to feed the recording paper sheet along the paper guide. When the recording paper sheet is loaded, a lever serves to separate the paper holding rollers from the platen. When a microswitch detects the operation of the lever, the platen is automatically rotated by a predetermined amount.
