<p>PURPOSE:To provide a reset circuit of an operation control circuit which requires a high voltage as its working power source when the control circuit controls the operations of electronic equipment and a low voltage when the control circuit makes a memory circuit to make storing operations. CONSTITUTION:The title reset circuit is provided with a voltage detection circuit 31 which detects that the voltage of a battery 17 drops to a prescribed value so that a boosting circuit 18 can be set to an operating state and a high voltage can be supplied to an operation control circuit 9 when a detecting signal is outputted from the circuit 31 and, at the same time, a reset signal can be inputted to the reset terminal 16 of the circuit 9.</p> |
