摘要： 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.

摘要： 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.

摘要： 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.
