Abstract:
1. An image sensor unit that emits light to an object to be illuminated and that reads reflected light from the object to be illuminated and/or transmitted light transmitted through the object to be illuminated, the image sensor unit comprising: a reflection reading light guide that emits light of a reflection reading light source, from an emission surface to the object to be illuminated; a transmission reading light guide that emits light of a transmission reading light source, from an emission surface to the object to be illuminated; an imaging element that focuses the reflected light from the object to be illuminated and/or the transmitted light transmitted through the object to be illuminated; a light receiving element that receives the light from the imaging element; and a frame comprising a housing portion housing the reflection reading light guide, wherein the reflection reading light guide comprises a first locking portion abutted with the frame, on a side away from an optical axis of the imaging element, near the emission surface of the reflection reading light guide, the frame comprises a light blocking portion that is abutted with the first locking portion and that covers part of the emission surface of the reflection reading light guide, the reflection reading light guide comprises a second locking portion opposing the emission surface of the reflection reading light guide and abutted with the frame, on a side close to the optical axis, the frame comprises a stepped portion abutted with the second locking portion, and the light blocking portion and the stepped portion sandwich the reflection reading light guide to position the reflection reading light guide.
