Abstract
The rotary motion of a driving cam driven by a driving motor is converted into both the upward and downward movement of a deck member and the forward and backward movement of a tray, so that the deck member and the tray can be driven by a single motor. Further, the conversion into the upward and downward movement of the deck member and the forward and backward movement of the tray is performed by the engagement of a pin of the driving cam with a straight groove and a circular groove of a driving lever. Since the straight groove is extended in the tangential direction of the driving cam, when the pin engages with the straight groove, the driving lever receive a force to slow down the opening and closing speed of the tray at the beginning and end of the movement, thereby improving the quality of the loading operation.
