An imaging unit comprises a mount unit, an imaging element unit, a plurality of elastic members and adjustment screws, and a filler member. The imaging element unit is disposed so that a gap is present with respect to the mount unit. The elastic members are disposed in a compressed state between the mount unit and the imaging element unit. The adjustment screws are disposed so as to be coaxial with respect to each of the elastic members and are mounted to at least one of the mount unit and the imaging element unit. The filler member is disposed so as to be coaxial with respect to at least one set comprising an elastic member and an adjustment screw, and, as the adjustment screw is tightened, the filler member is sandwiched and compressed between the mount unit and the imaging element unit.

Imaging unit

The imaging apparatus includes a lens mount to which a lens unit is mountable, an imaging unit operable to generate an image signal, and a shutter unit that is arranged between the lens mount and the imaging unit, and is capable of limiting the light incident on the imaging unit, opening and closing at least at recording and being kept in an opened state during a recording preparation operation, and a main frame to which the lens mount, the shutter unit and the imaging unit are fixed.

Imaging apparatus including metal main frame as assembly basis

A shutter drive device includes a base member, an actuator, a first drive member, and a second drive member. The actuator is fixed to the base member and produces a driving force to drive the shutter mechanism. The first drive member is rotatably supported by the base member and configured to be rotated by the driving force. The second drive member is supported by the base member so as to be linearly movable in a first direction and configured to transmit the driving force of the actuator to the shutter mechanism. The first drive member has a gear component to drive the second drive member in the first direction, and a cam component configured to hold the second drive member in a specific position. The second drive member has a rack gear configured to mesh with the gear component, and a cam follower configured to contact the cam component.

A heat dissipating structure for an imaging unit includes an imaging element configured to convert light into an electrical signal, a first heat dissipating plate, a second heat dissipating plate, and a heat dissipating portion. The first heat dissipating plate has a first end and a second end disposed opposite to the first end, and is positioned on the rear face side of the imaging element. The second heat dissipating plate is positioned on the rear face side of the first heat dissipating plate. The heat dissipating portion is fixedly coupled to the first end of the second heat dissipating plate.

Imaging apparatus containing lens mount without mirror box

An image pickup apparatus of the present invention includes a mechanical lock mechanism capable of holding a first curtain and a second curtain in an open state mechanically and a controller that controls the mechanical lock mechanism so as to hold the second curtain in the open state and controls a display so as to display image data generated based on a subject image incident upon an image pickup element as a moving image while the first curtain is in the open state.
