Abstract
A first supporting member supports a third supporting member of an image sensor unit that includes an image sensor supported by a second supporting member, and an adjusting member is provided between the image sensor unit and the first supporting member, and adjusts an imaging surface of the image sensor and a reference plane of the first supporting member so as to be parallel to each other at a first distance. A shaft portion of the image sensor unit fits into a hole provided in the second supporting member so as to be slidable in a direction perpendicular to the imaging surface and supports the second supporting member with respect to the third supporting member. A thermally deformable member is provided between the shaft portion and the hole and deforms to suppress a change in the first distance due to a change in temperature.
Claims27
An electronic device comprising:
- an image sensor unit that includes an image sensor;
- a first supporting member that supports the image sensor unit;
- and
- an adjusting member, provided between the image sensor unit and the first supporting member, that adjusts an imaging surface of the image sensor and a reference plane of the first supporting member so as to be parallel to each other at a predetermined first distance,
- wherein the image sensor unit comprises:
- the image sensor;
- a second supporting member that supports the image sensor;
- a third supporting member that is supported by the first supporting member;
- a shaft portion that fits into a hole provided in the second supporting member so as to be slidable in a direction perpendicular to the imaging surface and supports the second supporting member with respect to the third supporting member;
- a thermally deformable member that is provided between a top end surface of the shaft portion on a side fitted to the hole and a bottom surface of the hole and deforms in accordance with temperature;
- and
- a biasing member that biases the second supporting member toward the third supporting member in a direction perpendicular to the imaging surface,
- wherein the thermally deformable member suppresses a change in the first distance due to a change in temperature, by deforming in accordance with temperature.
