An image pickup apparatus, having a casing including an image pickup device, includes: a casing that surrounds a shooting light flux and has a length in a direction of the shooting light flux; an image pickup device that receives the shooting light flux at a terminal end of the shooting light flux in the casing and picks up an image; a planar electric substrate arranged in parallel to an optical axis of the shooting light flux, outside an image pickup surface of the image pickup device; an electronic element mounted on the electric substrate, the electronic element generating heat along with operation of an electronic circuit; a heat transmission sheet placed on the electronic element; and a heat sink placed on the heat transmission sheet so that the heat transmission sheet is held together with the electronic element between the electric substrate and the heat sink.

Heat management system for use in an image pickup apparatus

An electronic imaging device is provided which includes a first lens group which takes in a luminous flux from a subject along a first optical axis, an optical axis conversion member which bends the luminous flux along a second optical axis which intersects with the first optical axis, a second lens which images the bent luminous flux to an imaging element, and an optical amount adjustment unit provided between the second lens group and the optical axis conversion member. An AF motor, a driving unit which drives the optical amount adjustment unit, and a zoom motor are each selectively arranged at one of four spaces formed by a first plane defined by the optical amount adjustment unit and a second plane defined by the first and second optical axes. The AF motor, the driving unit, and the zoom motor may all be arranged at one side of the second plane.

Electronic imaging device

The first electronic imaging device, which performs a photoelectric-conversion of a subject light with an imaging element and records it, according to the present invention is characterized by comprising a first lens arranged along a first optical axis to take a luminous flux from the subject, an optical axis conversion material which bends the luminous flux which passes the first lens along a second optical axis which intersects with the first optical axis, a second lens which images the luminous flux bent along the second optical axis to the imaging element arranged on the second optical axis, and an optical amount adjustment device provided between the imaging element and the optical axis conversion material.

An optical apparatus according to the present invention includes a cylindrical holding barrel, a plurality of moving lens frames which are held in the holding barrel such that the moving lens frames are moved back and forth in an optical axis direction, and a cam cylinder fitted on an outer surface of the holding barrel so as to move the moving lens frames. The cam cylinder slides and rotates on the outer surface of the holding barrel, and includes a first cam cylinder and a second cam cylinder each having a cam section on an inner surface thereof, and one end face of the first cam cylinder and one end face of the second cam cylinder are coupled to each other such that the first and second cam cylinders are rotated together.
