Abstract
A paper loading apparatus includes a paper retaining roller and a stop claw, both arranged for movement toward or away from a platen in opposite directions from each other. When the stop claw bears against the platen, paper is inserted into the apparatus and is properly held by the claw. Subsequently, the paper retaining roller is brought into abutment against the platen, whereupon the stop claw is moved away from the platen. The movement of the roller and the stop claw toward or away from the platen occurs automatically in response to a detection signal which indicates the insertion of the paper into the apparatus. In one embodiment, the platen is peripherally formed with a plurality of axially spaced annular grooves which extend in a direction perpendicular to the axis thereof, and receive protuberances formed on the free end of the stop claw.
