摘要： An image reading apparatus includes an image capturing module for capturing an image of a document, a light source, a movable light reflecting surface having a white color, a driving module for moving the light reflecting surface into a first position at which the light reflecting surface reflects light from the light source and a second position at which the light reflecting surface does not reflect light from the light source, and a control module for controlling the driving module to move the light reflecting surface. The control module determines the second position by moving the light reflecting surface by a predetermined quantity from the first position determined based on an image obtained by the image capturing module.

摘要： A lighting device includes a light source, a board, and a light guide. The light source emits light. The board mounts the light source on a mount surface perpendicular to a light emission surface of the light source. The light guide has an incident surface which the light emitted from the light source enters. The incident surface is opposed to the light emission surface. The light guide extends from the incident surface in a direction of the emitted light and is bent toward an irradiated surface of an irradiation target on a way of the light guide. The board is disposed such that an opposite surface of the board opposite the mount surface is opposed to the irradiated surface of the irradiation target.
