Abstract: An elongate light guide includes a light incident portion provided at an end in the longitudinal direction of the guide, a light reflecting portion extending in the longitudinal direction, a light emitting portion extending in the longitudinal direction for emitting linear light, and a scatterer for scattering the light entering through the light incident portion. For instance, the scatterer is provided as a grained portion formed at least part of the reflecting portion.

Abstract: An LED module includes first through third LED chips and two Zener diodes for preventing excessive voltage application to the first and the second LED chips. A first lead includes a mount portion on which the first through third LED chips and the two Zener diodes are mounted. A resin package covers part of the first lead and includes an opening for exposing the three LED chips and two Zener diodes. A single insulating layer bonds the first and second LED chips to the first lead. A single conductive layer bonds the third LED chip and two Zener diodes to the first lead. The Zener diodes are arranged between the first, second LED chips and the third LED chip.

Abstract: An image reading apparatus of the present invention includes a first light source, a first light guide, a second light source, a second light guide, light receiving elements and a lens unit. The first light source emits first light. The first light guide directs the first light from the first light source toward an image-carrying object as first linear light extending in a primary scanning direction. The second light source emits second light of a wavelength different from that of the first light. The second light guide directs the second light from the second light source toward the image-carrying object as second linear light extending in the primary scanning direction. The light receiving elements are arranged in the primary scanning direction. The first and second linear lights are reflected by the image-carrying object, and the reflected lights are guided by the lens unit toward the light receiving elements.
