Abstract
An electronic apparatus detachably attached to an accessory via an accessory shoe includes contacts electrically connectable to the accessory via the accessory shoe and arranged in a row. The contacts include a first signal contact used to transmit a data signal in a communication between the electronic apparatus and accessory, a second signal contact used to transmit a clock signal in synchronization with the data signal in the communication, and a third signal contact used to receive a communication request signal from the accessory. The first and second signal contacts are arranged next to each other. The third signal contact is disposed on an opposite side of than the second signal contact with respect to the first signal contact. A transmission of the data signal via the first signal contact is executed in response to a reception of the communication request signal via the third signal contact.
