INTERCEPTING APPARATUS FOR RAY BEAMS OF LIGHTS

摘要

The apparatus shuts off the direct light reaching the film not through the reflection mirror in the tele mode. The dual camera (1) with a tele mode lens (2) and wide mode lens (3) includes a first reflection mirror (6A) placed on the axis of the tele mode lens, and a second reflection mirror (6B) placed on the inclined face of a shutter (8) which is located between a film (5) and the first mirror. A rotatable shutter base (11) linked to a shutter (12) is placed on the bottom of a fixing frame (7) of the first mirror so that the shutter closes the direct light path in the tele mode.
