<p>PURPOSE:To remove a reset switch and to allow a third person to easily reset a microcomputer by using a connection terminal for inputting data to the microcomputer also for resetting the microcomputer. CONSTITUTION:A decoder 8 is constituted so that when a voltage level reaches a prescribed voltage level, a reset signal is outputted to the reset terminal of the microcomputer 1. Namely, when the voltage level of the input terminal goes the prescribed voltage level, the decoder 8 outputs the reset signal to the reset terminal of the microcomputer 1 to reset the microcomputer 1. Since it is unnecessary to prepare an exclusive reset switch, the number of parts can be reduced, and since a locked operation mode can be reset by the third person, owner's objective picture recording or the like can be prevented from being interrupted.</p> |
