Description of the invention () Background of the invention: The present invention provides a stereoscopic projection frame and a masking volume guide device *, especially a Ricket color film frame that is easy to operate. And masking volume guidance device. The conventional technology is shown in Figure 10. • 傜 indicates the left and right photography planes PL and PR of the stereo camera. Due to the difference in the field of view of the left and right photographic lenses of the stereo camera, the left end portion A and B of the left screen PL and the right The area between the CDs at the right end of the PR screen is the part where the left and right screens do not overlap. This non-repeating portion Α-Β, C-D • It does not form a stereo image when viewed with a stereo projector. That is to say, as shown in FIG. 11 • When viewed with two eyes, the vertical line is seen at the edge of the window where the overlapping part and the non-repeating part focus on the other side. To prevent this, the window width of the stereoscopic projection frame is narrower than that of the projection projection plate to mask the non-repeating portions A-B and C-D. Figure 12 shows a paper stereoscopic projection frame 1. The upper half is folded forward at the position of the fold line 2 on the top and bottom. • The upper side cover frame 3 and the lower half back frame can be formed. 4 phase joint. The cover frame 3 and the bottom frame 4 each have pierced windows 5L, 5R, 6L, and 6R on their left and right sides, and the windows are arranged symmetrically with the fold line 2 as an axis of symmetry. The windows 6L of the bottom frame 4 are printed on top and bottom of the frame 4 as the projection position of the film. The reference lines 7, 8 are cut into one of the first lens. The left side projection M of the stereo projection M is aligned with the lower left window 6L. After the positioning, attach the edge part. Similarly, the right lanthanum stereo projection M is aligned with the lower right window 6R. After positioning, the edge part is connected. Then the cover frame 3 is folded and connected to the bottom frame 4. When positioning the projection slides, use a device rule to write the pitch P1 on the transparent plastic plate or glass plate to the left and right windows of the three-dimensional projection M frame 1.

Assemble I order ^ I μ (Please read the precautions on the back before filling out this page) Α7 Β7 Marks by the Consumer Cooperatives of the Central Standards Bureau of the Ministry of Economic Affairs of the People ’s Republic of China 5. Inventive Notes () Marks such as pitch The left and right pitches of the scene are taken equal to the pitch P1 of the window for positioning. At this time, if it is a landscape photo, the positions of the photographed objects on the left and right screens are the same for distantly illuminated objects * _ The film pitch and the window pitch P1 can be adjusted to be approximately equal, and the closer the photographed distance of the photographed objects · Due to the parallax of the left and right lenses, the photographed scenes on the left and right screens are close to each other. * If the pitch of the left and right illuminated scenes is taken to be equal to the window pitch P1, then the PΗ pitch is expanded than the window pitch P1. Therefore, in order to conceal the non-heavy rear part of the left and right screens, and not to expose the inner edges of the left and right screens, a variety of stereoscopic projections are prepared in which the center pitch P1 of the window is the same and the window width W is divided into different stages. According to the color distance of the photographed scene, select the stereoscopic slide frame. The present inventors have also proposed that a stand-up slide can be a stand-up slide frame of a fixed pitch device. As shown in 圏 13. The stereoscopic projection M frame is composed of a cover frame 11 and a bottom frame. The cover frame 11 and the bottom frame 12 are each provided with windows 13L, 13R, 14L, and 14R. The four corners of the windows 14L and 14R of the bottom frame 12 are provided with positioning pins 15 which are matched with the perforations of the color film to be fixed and make the pictures of the two projection films consistent with the windows 14L and 14R. The windows 13L and 13R of the frame 11 are provided with holes 16 opposite to the positioning pin 15. The positioning pin 15 and the hole 16 are fitted to engage the bottom frame 12 and the cover frame 11. The stereoscopic slide frame is suitable for the stereo camera proposed by the present invention. The perforation of the stereo camera and the relative position of the picture can be the same on the left and right. At the same time, it has a transfer mechanism of the left and right lenses to adjust the center distance of the lens It can make the most appropriate parallax for stereoscopic photography.
