PURPOSE:To simplify the circuit constitution and to attain a cost reduction, by providing an input/output port between a signal and a driving circuit which drive each part of a floppy disk device. CONSTITUTION:A control circuit 211 is actuated with the external signal supplied via a common connector 25, and then a selection control circuit 215 is driven. Then I/O ports 212 and 222 of a floopy disk device are selectively actuated, and therefore corresponding driving circuit 214 and 224 are actuated to drive a mechanism part. This simplifies the circuit constitution and reduces the cost for a floppy disk controller. |
