Abstract: An accessory that is attached to and detachable from an attachment portion provided to an electronic apparatus includes an engagement portion configured to engage the accessory with the attachment portion to hold the accessory in a case where the accessory disposed at a first position relative to the attachment portion is rotated to a second position in a first direction, and a plurality of contacts arranged in the first direction and connectable to corresponding terminals among a plurality of terminals arranged in the first direction and provided to the attachment portion at the second position. An interval angle between adjacent contacts among the plurality of contacts is larger than a rotational angle of the accessory from the first position to the second position.

Abstract: An image pickup apparatus which reduces variations in volume of voice data recorded by a voice memo function without increasing the number of components therein. The image pickup apparatus, having a first and a second display part, determines a display destination of image data according to a detection result of an eye approach detection part, and performs synthesis processing of adding voice data recorded by a sound collecting member to the image data, wherein in a case where user's eye approach is detected by the eye approach detection part and the image data is displayed on the second display part, when voice recording is started by a user operation, a first sound collecting sensitivity adjustment process of adjusting a sound collecting sensitivity of the sound collecting member is performed.

Abstract: In an electronic apparatus using the Molded Interconnect Device technology, a circuit member includes a fastened portion, to which the fastening member is fixed, and a plurality of convex portions arranged in an approximately circular shape around the fastened portion as a center. Each of the plurality of convex portions has a first contact pattern. A substrate has a hole portion into which the fastening member is inserted. The substrate has a plurality of second contact patterns arranged in an approximately circular shape on the substrate around the hole portion as a center so that each of the second contact patterns faces a corresponding one of the first contact patterns. The first contact patterns and the second contact patterns are brought into contact with each other by fixing the fastening member to the fastened portion through the hole portion.

Abstract: An electronic apparatus includes a control apparatus having a main body, a rotatable member rotatably supported by the main body, a magneto rheological fluid provided between the main body and the rotatable member, and a magnetic field generator configured to apply a magnetic field to the magneto rheological fluid, a plurality of rotatable operation members, and an operational feeling transmitter configured to transmit an operational feeling of the control apparatus to the plurality of rotatable operation members. When a switching member changes a transmission state of the operational feeling transmitter, a rotatable operation member to be used is selected from the plurality of rotatable operation members.
