Patent ID: 7034882

Claim:
An electronic camera comprising: a photographic lens configured to form an object image; an image sensing element configured to photoelectrically convert the formed object image; a light guiding device configured to guide incident light from an object, which is incident from the photographic lens, to a first optical path to the image sensing element and a second optical path different from the first optical path; a holding frame structure made of a heat-conducting material and configured to surround and fix the image sensing element and the light guiding device, so as to hold the image sensing element and the light guiding device in the electronic camera, wherein the holding frame structure comprises an intimately contacting member formed of a plate member larger than the image sensing element, made of a heat-conducting material, and intimately contacting with the image sensing element to transfer heat generated by the image sensing element, and a heat-transfer frame member made of a heat-conducting material and surrounding the light guiding device, such that the intimately contacting member and the heat-transfer frame member intimately contact with each other to transfer heat generated by the image sensing element through the intimately contacting member to the heat-transfer frame member; a lens casing configured to accommodate the photographic lens, the lens casing comprising a heat-radiating portion made of a heat-conducting material and configured to radiate heat to an outside of the camera and an outer casing accommodating the image sensing element; wherein the holding frame structure and the lens casing are arranged such that heat from the heat-transfer frame member is conducted to the heat-radiating portion of the lens casing.
