<p>PURPOSE:To cope flexibly with the contents of an image processing, a classification of a device of a file storage device for saving an image data, etc., by generating an instruction for instructing an inhibition of a disconnection of a power source by a software, and extending a power source disconnection start timing, in case an external interruption for disconnecting the power source has been generated. CONSTITUTION:When a power OFF switch 1a is depressed, a power source disconnecting the mechanism 2 is started and a counter 2a starts a count operation. On the other hand, when a software enters into a power source disconnecting routine by an interrupting signal 1c to the software, an OS retrieves a power source disconnecting command group on a main storage device. A necessary saving time corresponding to a classification of a device of a file storage device is set in advance to its command group. When its command group is read out, set to a command decoding circuit 3a, a power source disconnection inhibition detecting signal is outputted, the counter 2a is reset and allowed to count again, and it is delayed to send out a power source disconnection start signal.</p> |
