Publication number: 20240085764Abstract: An electronic apparatus includes a plurality of contacts electrically connectable to an accessory and arranged in a first direction orthogonal to a direction in which the accessory is attached. The contacts include an attachment detection contact to detect an attachment of the accessory to the electronic apparatus, and a communication request contact for a communication request from the accessory to the electronic apparatus. The attachment detection and communication request contacts are disposed between a contact closest one end and a contact closest to another end in the first direction. The attachment detection contact is disposed between the communication request contact and the contact closest to the one end. In the first direction, a distance between the attachment detection contact and the communication request contact is shorter than that between the communication request contact and the contact closest to the other end.Type: ApplicationFiled: November 20, 2023Publication date: March 14, 2024Inventors: Hiromichi Sakamoto, Kei Tohyama, Takayuki Shu, Hiromi Hayasaki, Kouji Ikeda, Yuhei Hattori, Kenji Ishii, Yoshinobu Okano
