Abstract: A light emitting unit is provided. The light emitting unit comprises a substrate, a light emitting element placed on a first surface of the substrate, a front panel covering the first surface, and a back panel placed on a second surface of the substrate, which is opposite to the first surface. An opening for extracting light emitted by the light emitting element is formed in the front panel, and the opening is formed to overlap a part of a light emitting surface of the light emitting element. The back panel has a thermal conductivity higher than that of the front panel, and includes a projecting portion that projects toward the first surface. The projecting portion is in contact with at least one of the first surface, the light emitting element, or the front panel.

Abstract: A first reflection light guide includes an axial part as an end part, and a main body part, has a linear rod-like shape including the end part and the main body part, and allows light from a first reflection light source to enter the end part and to be emitted from the main body part. The end part of the first reflection light guide is narrower than the main body part, and includes a contact surface in contact with a cap. The cap includes a light source side opening. A first reflection light source is arranged at the light source side opening. The first reflection light source faces the end part.

Abstract: An image sensor unit includes: a light condenser that collects light from the reading target object; an image sensor that receives the collected light collected and converts it into an electric signal; a housing having an elongated shape housing the light condenser and image sensor; and an elongated rigid member provided on a side surface elongated in an elongated direction of the housing. The housing has a multiple positions for fixation on the side surface. The rigid member is fixed to the side surface of the housing at at least two positions. A warping amount adjusting part is provided between the positions at which the rigid member is fixed. The warping amount adjusting part is capable of holding warping amount in the direction of the optical axis of the light condenser of the housing by intervention of a warping amount adjusting member between the rigid member and the housing.

Abstract: An image sensor unit includes: multiple first light guides that shape light emitted by light sources into a line and emit linear light elongated in longitudinal direction to an object to be read (P); multiple holding members that hold each of the first light guides on a frame; and an image sensor that detects light from the object to be read (P). The multiple first light guides are parallel, and in a range in which the image sensor detects the light from the object to be read (P) in the longitudinal direction of the first light guides, center positions in the main-scan direction of the multiple holding members that hold one first light guide of the multiple light guides and center positions in the main-scan direction of the multiple holding members that hold another light guide different from the one first light guide deviate from each other.
