回路。[Claims for Utility Model Registration] A Sensat microcomputer is installed in a vehicle via an accessory contact of a key switch, in a state where data regarding the operating state of the vehicle is obtained by the microcomputer. The microcomputer is connected to a battery and driven by the battery, and the microcomputer is connected to the battery via a switching means connected in parallel with the key switch, and when the key switch is turned OFF, the microcomputer is not connected to the battery, and the microcomputer is connected to the battery through a switching means connected in parallel with the key switch. When the power supply is stopped, the microcomputer is temporarily driven through the switching means, and after the microcomputer completes necessary processing, the switching means is opened by the microcomputer's own instructions. and stop its drive. A power supply circuit for an operation control device, characterized in that the power supply circuit is configured to stop.
