回路。 In a reset circuit that resets a microcomputer that controls an electronic device when its program runs out of control, there is a momentary type switch that switches the operation of the electronic device when operated, and automatically returns the operator after the operation is completed. a first switching element that is turned on when the switch is operated; a second switching element that is turned on when the switch is not operated and turned off when the first switching element is turned on;
A capacitor that is charged by operating the switch and discharged by turning on the second switching element, a resistor that determines a charging time constant of the capacitor in consideration of the capacitance of the capacitor, and a resistor provided in the microcomputer. a reset terminal which is turned on in accordance with the terminal voltage of the capacitor and which applies a reset signal to the reset terminal in the on state; The capacitor is discharged after the operation of the switch is completed, and even if the switch is repeatedly operated, a reset signal is not applied to the reset terminal until the operation time of the switch reaches a predetermined time. A reset circuit characterized in that the switch can be used as a switch for resetting the microcomputer in addition to switching the operation of electronic equipment.
