Abstract

The invention is to provide a masking quantity guiding device capable of testing a proper masking quantity by observing a stereo slide film strip. Projection lenses 13L and 13R and reticles 14L and 14R are provided in a frame 54 and a film guide 16 is arranged in the rear of the projection lenses 13L and 13R. Left and right lens boards 52L and 52R are engaged with the guiding slots 55L and 55R of the frame respectively. The left and right guiding slots are slanted to be mirror-symmetric with respect to an optical axis and the lens boards are slanted by the rotation of a cam shaft 25, so that the inside edges of the reticles always coincide with the inside edges of projected pictures regardless of projection magnification. A photographer rotates the cam shaft, while observing the images of the reticles, to obtain a state where the images can be seen in the same plane as the collimation patterns of the reticles or behind the patterns. Thus, when the photographer looks at the number of a dial attached to the cam shaft, the photographer can obtain the number of a stereo slide mount at an optimum picture masking ratio.
