特徴とする電子機器。 In an electronic device having a built-in floppy disk device and configured to control writing and reading of data to and from the floppy disk device by a floppy disk controller, means for controlling power supply to the floppy disk device; means for detecting the presence or absence of power supply to the floppy disk device;
Buffer circuit means is provided which is composed of a CMOS gate and capable of taking three states, and which blocks a signal path between the floppy disk control section and the floppy disk device, and the buffer circuit means is controlled by the output of the detection means, and the buffer circuit is connected to the floppy disk device. An electronic device characterized in that the buffer circuit means is placed in a high impedance state and the signal path is cut off when power is cut off.
