Claim 23:
24. An electronic apparatus to which an accessory is detachably attached, the electronic apparatus comprising a plurality of contacts electrically connectable to the accessory and arranged in a first direction orthogonal to a direction in which the accessory is attached,
wherein the plurality of contacts include an attachment detection contact used to detect an attachment of the accessory to the electronic apparatus, and a communication request contact used for a communication request from the accessory to the electronic apparatus,
wherein the attachment detection contact and the communication request contact are disposed between a contact closest one end and a contact closest to another end in the first direction,
wherein the attachment detection contact is disposed between the communication request contact and the contact closest to the one end,
wherein in the first direction, a distance between the attachment detection contact and the communication request contact is shorter than a distance between the communication request contact and the contact closest to the other end,
wherein communication contacts used for a communication between the electronic apparatus and the accessory are disposed between the attachment detection contact and the communication request contact and on an opposite side of the attachment detection contact with respect to the communication request contact, respectively,
wherein the electronic apparatus can communicate with the accessory by a first communication method and a second communication method different from the first communication method,
wherein a communication contact used for a communication in the first communication method is disposed on the opposite side of the attachment detection contact with respect to the communication request contact, and
