Imaging device
An imaging device includes an image sensor that captures an image of a subject, a first substrate on which the image sensor is mounted, a second substrate located frontward from the first substrate in an optical axis direction and having a first opening, and a lens barrel holding a lens. The image sensor receives light passing through the lens and the first opening.
1. An imaging device, comprising:
an image sensor configured to capture an image of a subject;
a first substrate on which the image sensor is mounted;
a second substrate located frontward from the first substrate in an optical axis direction, the second substrate having a first opening;
a lens, wherein the image sensor receives light passing through the lens and the first opening; and
a shield plate located between the first substrate and the second substrate, the shield plate having a second opening, wherein the shield plate includes leaf springs in contact with the first substrate and the second substrate and urging the first substrate and the second substrate.
2. The imaging device according to claim 1 , wherein
the first opening has an edge that allows, for the light passing through the lens, passage of a portion of the light corresponding to an effective imaging region to be received by the image sensor.
3. The imaging device according to claim 1 , wherein
the first opening is rectangular.
4. The imaging device according to claim 1 , wherein
the leaf springs each urge the first substrate or the second substrate in the optical axis direction.
5. The imaging device according to claim 1 , wherein
the shield plate has a surface treated with anti-reflective surface treatment.
6. The imaging device according to claim 5 , wherein
the shield plate has a front surface in the optical axis direction treated with anti-reflective surface treatment.
7. The imaging device according to claim 1 , wherein
the second opening is smaller than the first opening.
