Abstract: An image pickup unit that is capable of simplifying an optical adjustment work for an image pickup surface. A holding plate holds an image sensor. A lens barrel includes an optical system that forms an object image on the image sensor. A removable shim plate is inserted between the lens barrel and the holding plate and has a shape to avoid the image sensor. An energizing mechanism is inserted between the shim plate and the lens barrel to energizes the shim plate and the holding plate in a direction away from the lens barrel. Three adjusting screws fix the holding plate and shim plate to the lens barrel. Each of the adjusting screws displaces corresponding portions of the shim plate and holding plate toward the lens barrel when being fastened and displaces the corresponding portions away from the lens barrel in cooperation with the energizing mechanism when being loosened.

Abstract: A heat dissipation module suitable for a system camera formed by a plurality of modules. A heat dissipation module has a first engagement structure which is provided on a first surface and with which a first mating module is removably engaged and a second engagement structure is provided on a second surface parallel to the first surface and with which a second mating module is removably engaged. A first heat reception portion is configured to receive heat from the first mating module. The heat dissipation module also has a first interface electrically connected to the first mating module, and a second interface electrically connected to the first interface and electrically connected to the second mating module. A fan unit is provided between the first surface and the second surface, for dissipating heat received by the first heat reception portion to the outside.

Abstract: A body of an imaging apparatus comprises a mount section on which an interchangeable lens and a mount adapter can be mounted. A contact unit is movable in the direction of the optical axis by a moving mechanical unit and has a first contact portion composed of a plurality of contact terminals. If the interchangeable lens is mounted on a body via a first mount adapter, the first contact portion is movable to a first position that contacts a second contact portion formed in the interchangeable lens. If the interchangeable lens is mounted on the body via a second mount adapter, the first contact portion is movable to a second position that contacts the second contact portion of the interchangeable lens.

Abstract: A cylindrical member holding apparatus which is flexible in an axial direction of a cylindrical member and resists being deformed in directions perpendicular to the axial direction of the cylindrical member. A plurality of elastically-deformable supporting portions are disposed on respective opposite sides of the cylindrical member held by a holder portion in a direction of an axis of the cylindrical member and connect a base portion and the holder portion together. The supporting portions have such a shape as to be more easily elastically deformed in a first direction than in a second and third direction. The first direction is the axial direction of the cylindrical member, the second direction is a direction that is perpendicular to the first direction and connects the holder portion and the base portion together, and the third direction is perpendicular to the first direction and also perpendicular to the second direction.
