Light-guide plate, area light source apparatus, and image reading apparatus |
摘要 |
An LED module is mounted on a case frame by fitting three pins formed at a concave portion of the case frame, into holes formed to the LED module corresponding to the pins. A light-guide plate is fitted into the case frame formed integrally with a bottom cover in a descending direction. The light-guide plate is fixed by a hook provided for the case frame. In this case, a space between the light-guide plate and the LED module is prevented by pressing the light-guide plate to the LED module with a pressing spring. Since the light-guide plate is fitted into the case frame in the descending direction and a light scattering sheet is adhered to an outer end surface of the case frame in the descending direction, the reverse of a worked product is not required during a working process and the number and time of working processes can be saved.
