Abstract

[PROBLEMS] To reduce a communication error caused by a disconnection of part of terminals when an accessory is attached [SOLUTION MEANS] An accessory (200) detachably attached to an electronic apparatus (100) includes a plurality of contacts (TA01 to TA21) electrically connectable to the electronic apparatus and arranged in a row in a first direction orthogonal to a direction in which the accessory is attached to the electronic apparatus, a first protrusion portion arranged at a position on one outer side of the plurality of contacts in the first direction, and a second protrusion portion arranged at a position on another outer side of the plurality of contacts in the first direction. The first protrusion portion and the second protrusion portion protrude in a direction orthogonal to the direction in which the accessory is attached to the electronic apparatus and the first direction. The plurality of contacts include an attachment detection contact (TA06) used to detect an attachment of the accessory to the electronic apparatus, and a communication request contact (TA11) used for a communication request from the accessory to the electronic apparatus. The attachment detection contact and the communication request contact are disposed between a contact closest to the first protrusion portion and a contact closest to the second protrusion portion in the first direction. The attachment detection contact is disposed between the communication request contact and the contact closest to the first protrusion portion. 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 second protrusion portion.
