Abstract

PURPOSE:To facilitate the changeover action of the paper feeder in the caption by constituting the feeder in such a way that a sub-tray, which is vertically arranged in parallel with a main tray with the maximum capacity, is capable of vertically elevating at its retreated elevating position and, at the changeover position, the main tray is moved to such a position as not to prevent the movement of the sub-tray. CONSTITUTION:In the case that paper feed is changed over from an upper tray 120 (sub-tray) to a lower tray 103 (main tray), the upper tray 120 is lowered from a paper feed position by means of an upper tray driving motor 140, stopped, at a paper feed waiting position A by means of a waiting position detecting switch 142, and moved backward to an elevating position B by the action of the changeover driving motor 140. And then, the upper tray 120 is elevated by means of the upper tray driving motor 140 and stopped as a result of the detection of an upper limit position detecting means 136. Meanwhile, the lower tray 103 is kept at a predetermined position, for example, a position below a lowering position detected by means of a lower tray lowering position detecting switch 115, and next elevated by the drive of a lower tray driving motor 113 so that the paper feed position is moved.
