Abstract
An electronic apparatus to which an accessory is to be detachably attached includes a plurality of contacts electrically connectable to the accessory and arranged in a first direction orthogonal to an attachment direction of the accessory. The plurality of contacts include an attachment detection contact that is used to detect an attachment of the accessory to the electronic apparatus, and a first clock contact that is used to communicate a first clock signal in communication between the electronic apparatus and the accessory. A potential of the attachment detection contact changes from a predetermined potential to a reference potential different from the predetermined potential after the accessory is attached to the electronic apparatus. The attachment detection contact is disposed next to the first clock contact.
