てなるコネクタ接続検知回路。[Claims for Utility Model Registration] In a connector connection detection circuit that detects whether one device and another device are properly connected via a connector, an element provided in the one device is connected to the other device. In order to make the device operate or deactivate, the signal line originally provided in each of the above devices is connected via the connector, and the circuit originally provided in the other device to make the device operate or deactivate the signal line. By supplying a signal to the other device to operate the element, different signals are sent to the other device when the one device and the other device are connected and inactive via the connector. A connector connection detection circuit that includes an output circuit.
