## Abstract

There is provided an imaging device including a lens mount on which a lens is mounted, an image sensor that has an imaging face on which a subject image is formed by the lens, an image sensor holder on which the image sensor is mounted, biasing members that bias the image sensor holder in a direction of the lens mount, and an adjustment mechanism that is provided between the image sensor holder and the lens mount to adjust a distance between the imaging face and the lens mount.

## Claims

### Claim 1

An imaging device comprising:
a lens mount on which a lens is mounted;
an image sensor that has an imaging face on which a subject image is formed by the lens;
an image sensor holder on which the image sensor is mounted;
biasing members that bias the image sensor holder in a direction of the lens mount; and
an adjustment mechanism that is provided between the image sensor holder and the lens mount to adjust a distance between the imaging face and the lens mount.

### Claim 2 (depends on 1)

The imaging device according to claim 1,
wherein the adjustment mechanism includes
a slider that is disposed between the lens mount and the image sensor holder and is configured to be slidable in a direction orthogonal to an optical axis of the lens,
inclined faces that are provided on a side of the slider of the image sensor, and
protruding portions that are provided on the slider and abut the inclined faces by biasing force of the biasing members, and
wherein, with a movement of the slider in the direction orthogonal to the optical axis, the protruding portions relatively move with respect to the inclined faces, and the image sensor holder moves in a direction along the optical axis.

### Claim 3 (depends on 1)

The imaging device according to claim 1, wherein the biasing members are provided in two places that are diagonal on a face of the image sensor holder.

### Claim 4 (depends on 2)

The imaging device according to claim 2, wherein the protruding portions are provided in four places, and the inclined faces are provided in four places that correspond to the protruding portions.

### Claim 5 (depends on 2)

The imaging device according to claim 2, comprising:
a front chassis on which the lens mount is mounted,
wherein the front chassis has a regulating portion that regulates a movement of the image sensor holder in the direction orthogonal to the optical axis,
wherein the image sensor holder has an abutting portion that abuts the regulating portion of the front chassis by receiving force in a first direction orthogonal to the optical axis by the inclined faces, and
wherein the regulating portion has an inclined plane that exerts force on the abutting portions in a second direction that is orthogonal to the first direction and orthogonal to the optical axis.
