Abstract
A power supply detecting circuit detects feeding of power to a power supply terminal from the outside. A control unit identifies an accessory device connected to the connector based on a detection result acquired by the identification terminal voltage detecting circuit and a detection result acquired by the power supply detecting circuit. The identification terminal voltage detecting circuit can narrow down accessory device candidates based on whether or not there is feeding of power detected by the power supply detecting circuit.
