    Abstract: An image sensor unit performs image reading by reflected light and image reading by transmitted light with respect to a bill, and includes a reflection reading light guide that emits light from a reflection reading light source toward the bill, a transmission reading light guide that emits light from a transmission reading light source toward the bill, an imaging element that focuses light from the bill, and a light receiving element that receives light that is collected by the imaging element. The transmission reading light source and the transmission reading light guide are disposed on the opposite side of a conveyance path through which the bill can pass, for the reflection reading light source and the reflection reading light guide, and a light blocking member that blocks a part of the light from the reflection reading light guide is disposed between the reflection reading light guide and the transmission reading light guide.

    Abstract: A lighting device includes a light source that illuminates an object of illumination, a reflecting member provided opposite the light source so as to direct a first part of illuminating light emitted therefrom to the object of illumination, and a light-blocking member provided between the light source and the object of illumination and between the reflecting member and the object of illumination. The light-blocking member blocks the first directed part of the illuminating light and a second part of the illuminating light directly illuminating the object of illumination with a certain ratio of a light-blocking rate for the first directed part of the illuminating light to a light-blocking rate for the second directly illuminating part of the illuminating light.

    Abstract: A stray light baffle (10) for reducing an amount of stray light (70) and (70') incident on a detector (50) may comprise a main body portion (60) and a mounting pad portion (62). The mounting pad portion (62) is affixed to a mounting surface (88) with a light curable adhesive (86). The stray light baffle (10) substantially blocks stray light (70) and (70') and substantially transmits curing light. The mounting surface (88) is located adjacent the detector (50) so that the main body portion (60) of the stray light baffle (10) is interposed between the detector (50) and a source of stray light (70) and (70') when the stray light baffle (10) is mounted to the mounting surface (88).
