projection lens fixture

44R and 44L are installed on the projection lens support 43, the aforesaid distance of camera lens regulating device that constitutes by ball screw, be positioned on projection lens fixture 44R and the 44L, with the distance between the optical axis of regulating

projection lens

45R and 45L.

The a pair of right side and left focusing

flat plate fixture

46R and 46L are installed in the front end of lantern slide guide plate 42, and the focusing flat plate 47R of focusing

flat plate fixture

46R and 46L and 47L can be replaced.Similar to the stereopticon projector of Fig. 1, be positioned at the eyepiece fixture 10R and the 10L on focusing

flat plate

47R and 47L opposite, be fixed on the front end of lantern slide guide plate 42, and can be by rotation eyepiece fixture 10R and the eyepiece R of 10L and the barrel of L, scalable diopter.The scattering light source that the reflector plate 12 of semicircle and lighting bulb 13 are formed is arranged on the rear end of lantern slide guide plate 42.

44R is similar with 44L to projection camera lens fixture, and focusing

flat plate fixture

46R and 46L are installed on the ball screw device.The sheet screw 48 that advances that is positioned at the ball screw device on the right is right-hand threads, and what be positioned at the left side is the left hand screw thread.Be installed in the into focusing flat plate distance adjustment button 49 of the rear end of sheet screw 48 by rotation, can be on direction perpendicular to optical axis, make right and left focusing

flat plate fixture

46R and 46L branch are opened or approaching, and, can be in predetermined scope, on the spacing of focusing

flat plate

47R and 47L, from the reference spacing to the direction adjusted distance that is close each other.

Being used for mobile respectively film advances two lobe plates 50 and 51 of sheet device 31 and projection lens support 43, is installed in the into centre position of sheet screw 48.Shadoof 52 and 53 is placed on film and advances between sheet device 31 and the lobe plate 50, and between projection lens support 43 and the lobe plate 51, and by with stretch coil 54 and 55 with shadoof 52 and 53 energisings, film can be advanced that sheet device 31 and projecting mirror head bracket 43 move to and lobe plate 50 and 51 positions that closely link to each other.Therefore, can be by the dull and stereotyped distance adjustment button 49 of rotary-focusing, and being advanced sheet device 31 and projection lens support 43, film locks mutually with respect to the rotation of lobe plate 50 and 51, and, film advances sheet device 31 and projection lens support 43, can move forward and backward in image magnification ratio is scope between the back of projected position of 1: 1 o'clock the foremost of position and amplification.Two lobe plates 50 and 51 structure make projected image on focusing flat plate 47R and the 47L, have that total energy keeps the mobile ratio of focus state in film advances the moving range of sheet device 31 and projection lens support 43, thereby can be by any magnification enlarging projection picture.

When film advances sheet device 31 and projection lens support 43, on the direction that projection image amplifies when mobile, focusing

flat plate fixture

46R and 46L by mutually closely interlocking fix on the certain distance, and the picture frame of focusing

flat plate

47R and 47L, will cover on right and left focusing flat plate 47R and the 47L just as the outside.

At this moment, all be 30 millimeters if suppose the actual picture width of anaglyphic lantern slide and the picture width of focusing

flat plate

47R and 47L, so, for example, when the picture of lantern slide is exaggerated with projection, the projection image width then is 30 * 30/29=31.034 (millimeter), and 30 millimeters of the picture width of the width of projection image and focusing

flat plate

47R and 47L, differs 31.034-30=1.034 (millimeter).In other words, if focusing

flat plate

47R and 47L are placed on as shown in Figure 7 the original position, the projection image of amplification will exceed the right side and outside, the left side 1.034/2=0.517 (millimeter) of focusing

flat plate

47R and 47L.

For example, be under 30/29 the situation at the projection magnification ratio, the pitch of advancing sheet screw 48 is right and 0.517 millimeter of the mobile to the inside pitch of left focusing flat plate fixture 46R and 46L.Do not consider the projection magnification ratio, the inward flange of the picture region of focusing

flat plate

47R and 47L will be consistent with the inward flange of lantern slide projection picture, the exterior domain of projection image, the exterior domain that will exceed the focusing flat plate crested, and shaded areas will change continuously with the projection magnification ratio.So, when viewing and admiring the film of taking by the stereocamera that does not have the distance adjusting means between the optical axis, can regulate projection magnification ratio, and the exterior domain of picture covered suitably, so that watch the picture of best stereoeffect with shooting state.

When film is installed on the anaglyphic lantern slide erecting frame, by measure examination focusing flat plate 56 with cropping, the focusing flat plate 47R and the 47L that replace complete rough surface, this cropping measures examination focusing flat plate 56, have with as shown in Figure 8 the perpendicular line alignment so CP as main body, stereopticon projector 41 can be used as the cropping amount indicator.

When being used as the cropping amount indicator, in the dull and stereotyped distance adjustment knob 49 of rotary-focusing, can watch stereo-picture, when the preceding of the target of watching in nearly scope and after the position, in fact measuring the alignment so CP that tries focusing flat plate 56R and 56L with the cropping on right and a left side equates, or under the state of the depths of alignment so CP observation, the cropping amount becomes suitable cropping amount, and by satisfy condition at its window width the anaglyphic lantern slide erecting frame on film is installed, can reproduce accurate stereo-picture.

As shown in Figure 7, the numerical value identical with number is installed is displayed on the position of rotation of anaglyphic lantern slide erecting frame, or on the visual frame (polytype anaglyphic lantern slide erecting frame or visual frame have film pilot pin and different windows width), this image frame is proposed by applicant of the present invention, and covers ratio corresponding to the picture on the scale 57 of focusing flat plate distance adjustment button 49.Therefore, before the target of watching in nearly scope is placed on after on the position, in fact this position measures the alignment so CP that tries focusing flat plate 56R and 56L with cropping and equates, or become when the state of the depths of alignment so CP observation, if the numerical value of scale 47 is observed, the suitable quantity of anaglyphic lantern slide erecting frame or visual frame can be read out so, and can install with carrying out exactly easily.

Figure 11 has illustrated the stereopticon support that is applicable to 120 films, and it is just like cover frame 71 shown in Figure 11 (a) and the seat frame 72 shown in Figure 11 (b).Outshot 74R that shape engages with the hole of film and 74L are provided with the coboundary of the recessed film placement part 73 on the present frame 72, and

outshot

74R and 74L are placed on the center line of right and left window.The film that protuberate engages with the film placement part 73 of seat frame 72 is preserved part 75 and is formed on the cover frame 71 that engages with seat frame 72, and film retaining part 75 has the symmetric shape that comprises

recess

76R and 76L, and this

recess

76R and 76L engage with the outshot 74R and the 74L of seat frame 72.

Similar to aforesaid anaglyphic lantern slide mounting bracket or visual frame by applicant's proposition of the present invention, the anaglyphic lantern slide mounting bracket should seat frame 72 the right side and the spacing of

left window

77R and 77L be set to 63.5 millimeter, similar to the spacing of two eyes of people.The depth-width ratio of window 72R and 72L is identical with the dimension of picture of filstrip F, or more bigger than it, therefore can watch the whole picture of film F.When the set of diagrams sheet of the filstrip F of cutting apart by each frame is placed on the film placement part 73, and hole NR and NL be will engage with

outshot

74R and 74L the time, and the center of

window

77R and 77L will be consistent with the center of the picture of filstrip F.

With reference to Figure 12, the cover frame 71 that engages with polytype frame 72 is arranged, wherein right and the distance of

left window

78R and 78L and the width of window, equate with the distance C 1 of the window of seat frame 72 and the width W 0 of window, and the piecewise minimizing gradually of the width W of window quilt (#1, #2, #3).

When the cover frame 71 with the numerical value that obtains by the cropping measurement examination parts that use anaglyphic lantern slide projector 41 engages with a seat frame 72, can form the anaglyphic lantern slide that appropriate screen cropping amount is arranged that conforms to shooting state.

Anaglyphic lantern slide projector 81 does not as shown in figure 13 have to regulate the device of projection magnification ratio, but the regulating device of the distance that can regulate

projection lens

45R and 45L is arranged, and have and the identical focusing flat plate 47R of the anaglyphic lantern slide projector of Fig. 7 and the distance adjusting means of 47L.Advance the direction of the film guide plate 37 of sheet device 31 along film tapping and

plugging machine

61R and 61L are installed movably.

Bar 82R rotatably is connected with 44L with left projection lens fixture 44R with right in the horizontal direction with 82L, and the pivot point of
