Abstract
When a communication header transmit from the lens side to the body side is input, a reset and start detection signal is checked and if the lens is found to have been reset and started, a body/lens identify signal is communicated to exchange identification signals of each other and the like and resetting of the mechanism is instructed. Thus, malfunction of the lens can be prevented even when the microcomputer for the lens side is reset with the lens mounted on the body.
