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 a light emitting element, a light guide that has a substantially rod-like shape and shapes light emitted by the light emitting element into a line, a light condenser that focuses light from an illuminated object, an image sensor that detects the light focused by the light condenser, and a frame in which a light guide housing chamber that houses the light guide and an image sensor housing chamber that houses the image sensor are formed. A correction optical path that extends from the light guide to the image sensor without passing through the light condenser is formed in the frame.

Abstract: An illumination apparatus includes: a light source; a rod-like light guide having an incident surface that enters light from the light source that is disposed on one side in a main-scan direction, a diffusing surface that diffuses light that enters from the incident surface, and an emission surface that linearly emits light towards a bill; and a reflection member having a reflection surface that reflects light diffused by the diffusing surface to the light guide. The light guide has a locking projection that is locked in the reflection member on one side in the main-scan direction. The reflection member has a locking hole in which the locking projection is locked. A cut-out portion at which one part is cut out is formed in the locking hole.

Abstract: An illumination apparatus includes a light source and a light guide formed in a rod shape. An end surface in a longitudinal direction is an incident surface that receives light emitted from the light source. Diffusing patterns are formed on the light guide, and intervals between the diffusing patterns closer to the incident surface in a first area close to the incident surface are smaller than intervals between the diffusing patterns closer to the incident surface in a second area farther from the incident surface than the first area.
