<p>PURPOSE:To prevent a stock failure from occurring in any case by detecting a moving position of a stopper member being driven by a driving means, and regulating the stop position with a regulating means according to paper size. CONSTITUTION:A paper size signal is inputted, and supposing that it is a signal corresponding to a photointerrupter 12a, a motor 10 is rotated, moving a traveling member 4 in an arrow A direction, and when a shielding plate 11 is reached to a position shielding a beam of light heading for a light receiving part from a light emitting part of the photointerrupter 12a, a power circuit of the motor 10 is interrupted, stopping the motor 10, and each stop position of stop members 2a, 2b is set up. Likewise, when a size signal of paper corresponding to another photointerrupter 12b is inputted, the motor 10 is rotated in the reverse direction, moving the traveling member 4 in an arrow B direction, and at a time when the shielding plate 11 is moved to a position shielding this photointerrupter 12b, rotation of the motor 10 is stopped, setting it to the stop position of the stopper members 2a, 2b.</p> |
