The contacts include a plurality of functional signal contacts to which signals having functions that are different functions according to a type of the accessory are connected, reference potential contacts, to each of which a reference potential is connected, and contacts that are used to supply power to the accessory or to communicate with the accessory. The functional signal contacts include a first functional signal contact and a second functional signal contact. A distance from the first functional signal contact to a reference potential contact closest to the first functional signal contact and a distance from the second functional signal contact to a reference potential contact closest to the second functional signal contact are different from each other.

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.

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 first reference potential contacts that are contacts disposed at both ends of the plurality of contacts and are connected to a reference potential, and second reference potential contacts that are connected to the reference potential 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 of the plurality of contacts.

A shoe apparatus attachable to and detachable from an accessory shoe apparatus of an electronic apparatus in a first direction includes a plurality of connection terminals arranged in a second direction orthogonal to the first direction, a shoe engagement portion engageable with the accessory shoe apparatus, and a terminal protecting portion configured to project from the shoe engagement portion toward a tip side in the first direction and to protect the plurality of connection terminals. The plurality of connection terminals are exposed in a direction orthogonal to the first and second directions from the terminal protecting portion, and include slopes that tilt in an exposed direction from inside to outside in the second direction on both sides in the second direction of the terminal protecting portion.

Shoe apparatus, accessory, accessory shoe apparatus, and electronic apparatus

An electronic apparatus includes an accessory shoe via which an accessory is to be detachably attached to the electronic apparatus. The accessory shoe includes a plurality of contacts that is electrically connectable to the accessory and arranged in a row, and include an attachment detection contact, a power supply contact, and a first reference potential contact that is connected to a reference potential. A potential of the attachment detection contact becomes the reference 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 reference potential contact is disposed on another side. The first reference potential contact is disposed outside the power supply contact in an arrangement direction of the plurality of contacts.

An image forming method to be performed by an image forming apparatus includes forming, transferring, fixing, and drying. The forming forms a foil portion to which foil is adhered on one surface of a recording medium. The transferring transfers an image to the one surface of the recording medium after the forming of the foil portion. The fixing fixes the image transferred to the one surface of the recording medium by the transferring of the image, to form a foil image portion including the foil portion and the image on the recording medium. The drying dries the recording medium on which the foil portion is formed, between the forming of the foil portion and the transferring of the image.

An error correction coding apparatus that performs error correction coding using, as an error correction code sequence, a frame of m bits×n symbols input in m-bit parallel, where m and n are positive integers, includes: an error correction coding circuit that performs error correction coding using, as information bits, m bits×n symbols including known bits assigned to a bit sequence specified in the error correction code sequence and generate error correction coded parity bits; and a selector that replaces the known bits of the error correction code sequence with the parity bits.

Error correction coding apparatus and error correction decoding apparatus

An image capturing apparatus includes an image capturing element, a first circuit board to mount the image capturing element on the first circuit board, a second circuit board facing the first circuit board, a fan, and a first flexible board electrically connect the first circuit board and the second circuit board. The image capturing element moves within a movable range in a direction different from an optical axis direction. The first flexible board is bent in an area that overlaps with the movable range of the image capturing element in the optical axis direction. When viewed from a direction orthogonal to an optical axis, an orientation of an exhaust opening of the fan is arranged toward an inner surface of a bending portion of the first flexible board closest to the first circuit board at a center position of the movable range of the image capturing element.
