Title: Illuminator
Inventor: FUNAMOTO TATSUAKI
IPC: G02B6/00
Filed: 1997-07-25
Abstract: PROBLEM TO BE SOLVED: To provide a front end type illuminator whose visibility is made high both in the lit state and the unlit state of illumination, which is excellent in uniformity and whose power consumption is low. SOLUTION: When a light beam 9 made incident on the end face 14 of a light guide plate 1 from a light source 2 reaches a projection-shaped part 11, it is projected from the plate 1 and irradiates a body to be illuminated 3. The plate 1 is formed in wedged shape and made thin at a part far from the light source 2. Such shape is useful to uniformize illuminating light by preventing the density of luminous flux from lowering when the light beam is transmitted in the plate 1. The plate 1 has a function to project the light beam to the body 3 and transmit the light beam reflected by the body 3 almost without dispersing it.
