Abstract

PURPOSE: To improve operation by making it possible to adjust an error of a frame position and shift in phase automatically by moving an automatic correction lever by changing over a worm gear and change-over leger according to normal or reverse rotation of a projector.
CONSTITUTION: As the projector is changed over from the normal projection to reverse projection, main shaft 24 is reversed and claw 12 is placed in the opposite mode, so that film 11 will be moved up backwards and intermittently. Then, worm gear 26 is reversed and gear 27 stops to change over lever 29, so that automatic correction lever 20, claw 12, etc., move down around the contact point of cam 15 as its fulcrum. At this time, hook projection 14 of claw 12 ascends automatically to correct the framing automatically, so that the side part of a screen will not be vignetted. Further, even when normal projection is restarted, the frame position is automatically adjusted.
