ABSTRACT:
A printer has a paper rest on which one or more paper sheet is placed, feed rollers for feeding the paper sheet placed on the paper rest, and a printing head for printing an image on the paper sheet. The paper rest has a fixed rest portion, the inclination of which is fixed and a movable rest portion rotatably supported on the fixed rest portion and a torsion spring is interposed between the fixed rest portion and the movable rest portion for generating elastic force according to rotation of the movable rest portion. Due to self-weight of the paper sheets placed on the paper rest and the elastic force of the torsion spring, the movable rest portion is inclined more steep when the number of the paper sheets placed on the paper rest smaller and is inclined more gentle when the number of the paper sheets is larger.
