PURPOSE:To eliminate power consumption by making a consecutive new command of an ejection command means ineffective after ejection is executed. CONSTITUTION:A motor for ejecting a card is driven while an H level is applied to a + terminal of the motor in ejecting the card, the card C is pushed up via a gear (not shown) and a cam (not shown) keeps turning. Further, when the pushup cam turns around and returns to the home position and one pushup is finished, a home position signal of H level is outputted from an HP terminal. The signal is inputted to a one-shot pulse generating circuit P2 via a NAND gate G4, an H level pulse is inputted to a reset terminal R of a flip-flop F3, an output Q of the F3 goes to the L level, the + terminal of the motor M goes to the L level via a delay circuit D and the ejection is stopped. |
