Abstract:
PURPOSE: To realize low power consumption of the view finder using a liquid crystal panel illuminated by a back light.
CONSTITUTION: The view finder is contained in a housing 1, and provided with a liquid crystal panel 2, a back light 6 to be an illuminating light source of this liquid crystal panel, and an optical system 4 arranged in front of the liquid crystal panel. In the housing 1, a means for guiding a peripheral light into the liquid crystal panel 2 is also provided. This peripheral light guiding-in means is constituted of, for instance, a window 10 provided in the housing and a reflecting plate 8 for making the peripheral light passing through this window incident on the liquid crystal panel 2. The peripheral light entered from the window 10 illuminates the liquid crystal panel 2 from the back through the reflecting plate 8. In this regard, in the case of using the back light 6, it will suffice that the reflecting plate 8 is stored in a ceiling part of the housing 1, and also, the back light 6 is opposed to the liquid crystal panel 2.
