The optical system includes a mirror array in which a plurality of reflection mirrors are connected, and a plurality of aperture stops. Neighboring reflection mirrors reflect light at different angles viewed from the main scanning direction.

A reading module of the present disclosure is provided with a light source, an optical system, and a sensor. The optical system images, as reading light, reflected light of light radiated from the light source to an illumination object. The sensor converts the reading light imaged by the optical system into an electric signal. The optical system is provided with a mirror array in which a plurality of reflection mirrors are disposed in an array in a prescribed direction and a plurality of aperture stop portions that adjust an amount of the reading light. Each of the reflection mirrors is disposed at a prescribed distance from an adjacent one of the reflection mirrors in a prescribed direction.

An image sensor unit includes a light condenser that collects light from a reading target object; an image sensor that receives light and converts the light into an electric signal; an elongated housing that houses the light condenser and the image sensor; and an elongated rigid member attached to a side surface extending in the elongated direction of the housing. The side surface of the housing is provided with an attachment protrusion. The rigid member is provided with an attachment hole that penetrates from a surface facing the side surface of the housing to a non-facing surface on the opposite side, and the non-facing surface of the rigid member is provided with a concave. The attachment protrusion is inserted into the attachment hole, and a part of the attachment protrusion is fit into the concave.

An image reading device includes a contact plate, a frame, a carriage, and a flexible flat cable. The carriage includes a reading mechanism and a resin-made slider projectedly provided at both end portions of the reading mechanism in its extending direction, and reciprocally moves in a sub-scanning direction at a bottom surface side of the contact plate while the slider slides the bottom surface of the contact plate in the frame. The flexible flat cable is connected to an one side surface of the carriage so that a width direction thereof matches the main-scanning direction, is arranged so that a part continued from a portion where the flexible flat cable connects with the one side surface is curved in a U-shape to go around toward an underside of the carriage, and transmits an electric signal of the reading mechanism. The contact plate is applied with a fluorine coating.

An apparatus for recording distance profiles respectively having a plurality of distance image points comprises: (i) a plurality of transmitters arranged in an array respectively for the transmission of electromagnetic radiation into a recording region; (ii) at least one reception unit for the detection of radiation reflected from the recording region; (iii) an evaluation unit for determining distances of objects at which transmitted radiation is reflected, with the distances each forming a distance image point; and (iv) a deflection unit which deflects the transmitted radiation within a scanning angle region into a scanning direction in order to consecutively generate, per distance profile, a plurality of scanning patterns of distance image points that are displaced against one another in the scanning direction and that each image the transmitter array, wherein at least a few of the distance image points are spaced apart from one another in the scanning direction.
