Imaging apparatus
View Patent ↗An image capturing device includes: a casing at least partially including a metal part, an outer surface of the casing including at least a part of which is formed by the metal part; a lens mount provided on a front surface of the casing; an image sensor provided inside the casing, the image sensor being positioned rearward of the lens mount; a thermally conductive sheet that transfers heat generated from the image sensor, to the metal part of the casing; and an elastic member biasing the thermally conductive sheet toward an inner surface of the metal part of the casing to maintain contact between the thermally conductive sheet and the inner surface.
1 . An imaging apparatus comprising:
a casing at least partially including a metal part, an outer surface of the casing including at least a part of which is formed by the metal part;
a lens mount provided on a front surface of the casing;
an image sensor provided inside the casing, the image sensor being positioned rearward of the lens mount;
a thermally conductive sheet that transfers heat generated from the image sensor, to the metal part of the casing;
an elastic member biasing the thermally conductive sheet toward an inner surface of the metal part of the casing to maintain contact between the thermally conductive sheet and the inner surface; and
a retainer member provided inside the casing to face the inner surface at a distance from the inner surface, the retainer member receiving the elastic member,
wherein
the thermally conductive sheet includes a tip end portion entering between the inner surface and the retainer member,
the elastic member is arranged between the retainer member and the tip end portion of the thermally conductive sheet,
the retainer member is provided with a through hole through which the thermally conductive sheet passes, and
the tip end portion is arranged between the inner surface and the retainer member by bending a part of the thermally conductive sheet having passed through the through hole.
2 . The imaging apparatus according to claim 1 , wherein the metal part forms at least a part of a bottom surface of the casing.
3 . The imaging apparatus according to claim 2 , wherein
the casing includes a bottom casing, the bottom casing including the bottom surface of the casing, the bottom casing being detachable, and
the metal part is the bottom casing.
4 . An imaging apparatus comprising:
a casing at least partially including a metal part, an outer surface of the casing including at least a part of which is formed by the metal part;
