An image sensor includes: a lens configured to focus light irradiated toward an object to be read and reflected by the object to be read; a sensor configured to receive light focused by the lens; a sensor board configured to mount thereon the sensor; a board retaining plate, having a casing attachment surface extending in the X direction and a sensor board attachment reference surface that is in contact with the +Y side of the sensor board and is formed in a side surface of the casing attachment surface, and configured to retain the sensor board; and a first casing configured to fix or retain the board retaining plate by fastening of a surface of the casing attachment surface.

Image sensor

An image sensor includes: a lens configured to focus light after passing through or reflected by an object to be read and passing through a first transparent plate; a sensor arranged along the X direction and configured to receive the light focused by the lens; a first casing fixing the first transparent plate and containing or retaining the lens and the sensor; and a bracket arranged at the X direction end portion of the first casing and configured to seal the lens contained or retained by the first casing.

An image sensor including: light guides for irradiating light onto an irradiated object; a lens that focuses reflected light that was reflected by the irradiated object; a sensor that receives the reflected light that was focused by the lens; and a housing. The housing houses or holds the light guides, the lens, and the sensor, and is formed by integrating a housing metal portion and a housing resin portion.

An image reading device including: concave first lens mirrors that are arranged in an array shape along a main scanning direction and that collimate scattered light reflected by an irradiated object and reflect the scattered light as a substantially parallel bundle of rays that are angled in a sub-scanning direction; planar mirrors that reflect light from the first lens mirrors; apertures that are arranged in an array shape and that allow light from the planar mirrors to pass through by way of openings that are arranged in an array shape and that are light-shielded therearound for selectively allowing light to pass through; concave second lens mirrors that are arranged in an array shape into which light from the apertures is incident and that reflect the light from the apertures as converged light; and light receivers that have light receiving areas on which light from the second lens mirrors is incident and that form images that correspond to light from the openings.
