PURPOSE:To exactly stop a card at a prescribed position, by stopping a damping output is accordance with a decelerating state of a card carrying motor, and stopping the card exactly at a prescribed position. CONSTITUTION:A motor M is rotated in the forward direction by a start signal ST, and a card CD runs in the forward direction. The card is detected at the detecting position by a detecting element SS and a position detecting part CS, and a detecting output (a) is provided to a position selecting part PS. The position selecting part PS sends out a state of SW1 SWn which are selectively turned on in accordance with a stop position, to a counter TC. On the other hand, a pluse generating part PG generates a pulse signal (b) in accordance with rotation of the motor, inputs it to the counter TC, the counter TC is subtracted, and when a value of the counter becomes zero, and output (c) is provided to a driving part MD and a pulse width detecting part PT. The driving part MD is changed to an inverted output, and the pulse signal (b) is expanded in accordance with deceleration of the motor M. The pulse width expansion PT stops the driving part MD by a detecting output (e) when the pulse width has exceeded a prescribed value. |
