摘要:
An illuminating device (20) includes a light source (22) to generate an illumination light used for reading of an image, a light guide body (21) that extends in a specified direction and includes an incident surface (21a) which is formed at one end in the specified direction and on which the illumination light from the light source is incident, a reflecting surface (23r) to reflect the illumination light incident from the incident surface, a first exit surface (23a) through which a first light component reflected by the reflecting surface and directly directed to an image reading area passes, and a second exit surface (23b) which faces a direction different from the first exit surface and through which a second light component reflected by the reflecting surface and directed to a direction different from the first light component passes, and a reflecting member (25) to reflect the second light component exiting from the second exit surface to the image reading area.
