Abstract
An image reading apparatus includes a light-guide member that moves in a direction crossing a longitudinal direction of the light-guide member and that emits light, which has entered from an incident surface of the light-guide member, as light that is linearly distributed in the longitudinal direction, a light source that emits the light, and an optical fiber that guides the light emitted by the light source to the incident surface.
Claims7
An image reading apparatus comprising:
- a light-guide member configured to move in a direction crossing a longitudinal direction of the light-guide member,
- wherein the light-guide member is configured to emit light, which has entered from an incident surface of the light-guide member, as light that is linearly distributed in the longitudinal direction;
- a light source configured to emit the light;
- an optical fiber configured to guide the light emitted by the light source to the incident surface;
- an apparatus frame to which the light source is fixed;
- a scanning unit comprising a full-rate carriage configured to cause the light-guide member to move in the direction crossing the longitudinal direction;
- a half-rate carriage configured to move in the direction crossing the longitudinal direction, the half-rate carriage comprising a pulley;
- a CCD substrate;
- and
- a heat-radiation member that is disposed inside of the apparatus frame to which the light source is fixed and that is configured to radiate heat generated by the light source,
- wherein the heat-radiation member is disposed in an area located between ends of the light-guide member in the longitudinal direction, and
- wherein the optical fiber is wound around the pulley.
