摘要： [PROBLEMS] To suppress interference caused by a change in another signal with a communication signal
[SOLUTION MEANS] An electronic apparatus (100) has a plurality of contacts aligned and electrically connectable to an accessory (200). The plurality of contacts include first and second signal contacts (TC12, TC13) used to transmit a first signal as a data signal and a second signal as a clock signal in a communication between an electronic apparatus and an accessory, a third signal contact (TC14) used to transmit a third signal, and a fourth signal contact (TC11) used to transmit a fourth signal. The third and fourth signals are signals whose signal levels do not change during the communication of the first and second signals. The first and second signal contacts are arranged adjacent to each other, and the third signal contact is disposed on one of both sides of the first and second signal contacts, and the fourth signal contact is disposed on the other.-

摘要： [SUMMARY]
[PROBLEMS] To reduce the noise influence of a clock signal on a signal of an adjacent contact while suppressing an increase in the number of contacts.
[SOLUTION MEANS] An accessory (200) is attachable to and detachable from an electronic apparatus (100). The electronic apparatus includes a plurality of contacts electrically connectable to the accessory and arranged in a row. The plurality of contacts include an attachment detection contact (TC6) that is used to detect an attachment of the accessory to the electronic apparatus, and a first clock contact (TC07) 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 grounded potential after the accessory is attached to the electronic apparatus. The attachment detection contact is disposed next to the first clock contact.-

摘要： [PROBLEMS] To reduce the influence of short-circuiting between a power supply contact and its adjacent contact.
[SOLUTION MEANS] An electronic apparatus (100) includes a plurality of contacts electrically connectable to a detachably attached accessory (200) and arranged in a row. The plurality of contacts include an attachment detection contact (TC06) that is used to detect an attachment of the accessory to the electronic apparatus, a power supply contact (TA05) that is used to supply power from the electronic apparatus to the accessory, a communication contact (TA02, TA03, TA07-TA017, TA19, and TA20) for communication between the electronic apparatus and the accessory, and a first grounded contact (TA04) that is connected to ground. A potential of the attachment detection contact becomes a grounded potential in a case where the accessory is attached to the electronic apparatus. The attachment detection contact is disposed on one of both sides of the power supply contact, and the first grounded contact is disposed on another side.-

摘要： [SUMMARY]
[PROBLEMS] To reduce a communication error caused by a disconnection of part of terminals when the accessory is attached
[SOLUTION MEANS] An electronic apparatus (100) to which an accessory (200) is detachably attached includes a plurality of contacts (TC01 to TC21) electrically connectable to the accessory and arranged in a row. The plurality of contacts include an attachment detection contact (TC06) used to detect an attachment of the accessory to the electronic apparatus, and a communication request contact (TC11) 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 one end and a contact on closest to another end in an arrangement direction of the plurality of contacts. The attachment detection contact and is disposed between the communication request contact and the contact closest to the one end. In the arrangement 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.-

摘要： [PROBLEMS] To secure the connection of the reference potential contacts between the accessory and the electronic apparatus even if static pressure or impact is applied to the accessory
[SOLUTION MEANS] An electronic apparatus (100) to which an accessory (200) is to be detachably attached includes a plurality of contacts (TA01-TA21) electrically connectable to the accessory and arranged in a row. The plurality of contacts include a contact (TA02, TA03, TA05-TA017, TA19, TA20) that is used for power supply from the electronic apparatus to the accessory or for communication between the electronic apparatus and the accessory, first grounded contacts (TA01, TA21) that are contacts disposed at both ends of the plurality of contacts and are connected to ground, and second grounded contacts (TA04, TA18) that are connected to the ground and are contacts disposed at both ends of part of the plurality of contacts other than the first reference potential contacts in a case where the accessory is connected to the part.-

摘要： [PROBLEMS] To realize a function suitable for an attachment to the electronic apparatus in consideration for a relationship with other contacts.
[SOLUTION MEANS] An accessory (200) is attachable to and detachable from an electronic apparatus (100). The electronic apparatus includes a plurality of contacts electrically connectable to the accessory and arranged in a row. The plurality of contacts include a functional signal contact (TC17) to which a signal having a function that is different according to a type of accessory is connected, a reference potential contact (TC18) to which a reference potential is connected, and a contact that is used to supply power to the accessory or to communicate with the accessory. The functional signal contact and the reference potential contact are arranged next to each other.
