fig2 i the configuration of said circuit is shown in fig2 which is obtained by partially modifying the feed scan control circuit sc of the circuit configuration in fig1 a part necessary to explain such modification is only illustrated in fig2 the circuit comprises a pulse generator 139 for generating a predetermined number of pulses each time the output of the said switch 135 is reversed the pulse generator being connected to a driver 132 for driving the pulse motor m to give said pulses thereto a detection circuit 140 for obtaining a detection signal representing that the pulse motor m is working on the card 1 after the second pressing of the button 135 the circuit being consisting of a counter gate circuits and a flip flop and a feeding direction control circuit 137 for supplying to the driver 132 an output signal to render the feeding direction of the card 1 backward when the switch 135 is on or another output signal to render the feeding direction forward when the detection circuit 140 is producing the detection signal independently of the output of the flip flop 91 fig1 for instructing the feeding direction this circuit is operated as follows when the button 135 is pressed at a first time the switch is turned on to energize the pulse generator 139 which supplies a predetermined plural number of pulses to the driver 132 as shown in fig2 iii the card 1 is thus transferred backward by a predetermined number of rows this feed amount is set to be equal to the distance between the reference.
