Abstract
An image sensor module includes an elongated light emitting unit, a photodetector, a lens unit, a substrate with the photodetector mounted on. The substrate is spaced apart from the lens unit in a thickness direction of the substrate. The image sensor module further includes a resin case provided with a light emitting unit chamber, a lens unit chamber and a substrate chamber. The lens unit chamber has a first bottom face extending in the first direction, and the substrate chamber has a second bottom face extending in the first direction and facing opposite to the first bottom face in the thickness direction of the substrate. The first or second bottom face is formed with at least one protrusion extending in the thickness direction of the substrate.
Claims20
An image sensor module comprising:
- a light emitting unit that emits linear light to an object to be read, the linear light extending in a first direction;
- a photodetector extending in the first direction;
- a lens unit that converges light from the object on the photodetector;
- a substrate on which the photodetector is mounted, the substrate being spaced apart from the lens unit in a second direction orthogonal to the first direction;
- and
- a case formed of a resin material and defining a light emitting unit chamber in which the light emitting unit is accommodated, a lens unit chamber in which the lens unit is accommodated, and a substrate chamber in which the substrate is accommodated,
- wherein the lens unit chamber includes a lens unit chamber bottom face extending in the first direction,
- the substrate chamber includes a substrate chamber bottom face extending in the first direction and facing opposite to the lens unit chamber bottom face in the second direction, and
- at least one of the lens unit chamber bottom face and the substrate chamber bottom face is formed with at least one protrusion protruding in the second direction.
