Claims

[Claims for Utility Model Registration] (1) A reset device for a logic control circuit or the like in an electrical device in which a logic control circuit or a microcomputer with a memory function is installed to share the power supply with other loads, 7-inch means whose electrical state changes depending on the presence or absence of the power supply in the electrical equipment, and the memory of the logic control circuit, etc. is determined by the output of the detection means when the power supply is connected to and removed from the electrical equipment. A reset device that performs a reset operation to return the contents to their initial state. '(2) The switch means includes a differentiating circuit connected between the reset terminal of the logic control circuit and the power supply, a detection means for detecting the presence or absence of the power supply in the electrical equipment, and a a switch whose operation is controlled by the output of the means and which is electrically turned on when the power source is not present, and which is provided between the reset terminal and ground via the differential circuit; The reset device according to item 1. (3) The detection means includes a protrusion provided on a cartridge that holds a power source to be housed in the storage section of the electrical equipment main body, and a detection means that is located within the storage section and is connected to the switch, and that is in contact with the protrusion. The reset device according to claim 2, which is a utility model, and comprises a protrusion that controls the electrical state of the switch by contacting the protrusion.
