1. A camera device comprising:
- a camera including a lens and a lens barrel;
a first casing including a light-transmitting cover opposed to the lens;
a second casing which supports the camera such that the second casing is spaced from the light-transmitting cover with a gap, the second casing is enclosed by the first casing;
an air flow path which allows air within the second casing to flow out toward the light-transmitting cover via the gap,wherein the air flow path is positioned between the second casing and the lens barrel, anda heating member provided within the second casing,wherein the air warmed by the heating member flows into the air flow path,wherein the second casing has an opening, of which a width is greater than a width of the lens, formed by a distal end portion that is closer to the light-transmitting cover than the lens in an optical axis direction of the lens.

Abstract
A camera device includes: a camera including a lens; a first casing including a light-transmitting cover disposed to oppose the lens; a second casing which supports the camera within the first casing, and which surrounds the camera such that a side of the second casing opposing the light-transmitting cover is spaced from the camera with a gap; and an air flow path which allows air within the second casing to flow out toward the light-transmitting cover via the gap. The air flow path is formed between the second casing and a lens barrel of the lens.

13. A camera device comprising:
-
a first casing including a light-transmitting cover; a second casing, positioned in the first casing; a camera, including a lens and an imager, which is supported by and positioned in the second casing, the lens being positioned between the light-transmitting cover and the imager, the imager taking an image through the lens; an air flow path which is formed by an outer surface of the lens and an inner surface of the second casing and corresponds to a gap between the outer surface of the lens and the inner surface of the second casing; wherein the second casing has an opening, of which a width is greater than a width of the lens, formed by a distal end portion that is closer to the light-transmitting cover than the lens in an optical axis direction of the lens, wherein the imager is positioned in an upstream side of the air flow path and the distal end portion is positioned in a downstream side of the air flow path, wherein air warmed by the imager flows into the light-transmitting cover through the opening, the warmed air flowing from the upstream side to the downstream side. - View Dependent Claims (14, 15, 16, 17, 18, 19)

20. A camera device comprising:
-
a first casing including a light-transmitting cover; a second casing, positioned in the first casing, which has an opening formed by a distal end portion of the second casing; a camera, including a lens and an imager, which is supported by and positioned in the second casing, the lens being positioned between the light-transmitting cover and the imager, the imager taking an image through the lens; an air flow path which is formed by an outer surface of the lens and an inner surface of the second casing and corresponds to a gap between the outer surface of the lens and the inner surface of the second casing; wherein the imager is positioned in an upstream side of the air flow path and the distal end portion is positioned in a downstream side of the air flow path, wherein air warmed by the imager flows into the light-transmitting cover through the opening, the warmed air flowing from the upstream side to the downstream side, wherein a distance between the distal end portion and the light-transmitting cover in an optical axis direction of the lens is less than a distance between the lens and the light-transmitting cover in the optical axis direction of the lens.
