  The present invention displays a pair of stereo images in order to achieve the purpose of easily viewing the stereo images displayed on the electronic display and easily carrying them when taking and viewing stereo images outdoors. A stereo viewer and / or a stereo view finder for use in an electronic device including an electronic display, comprising: a light-shielding hood attached to the electronic display and foldable; and a pair of lenses for viewing a stereo image. This is realized by including a loupe that is attached to the inner wall portion via a hinge portion and can be deployed in parallel to the electronic display.

  A stereo viewer / stereo viewfinder according to a first embodiment of the present invention will be described below with reference to FIGS.

  As shown in FIG. 1, a stereo viewer / stereo viewfinder 1 is applied to a digital stereo camera (not shown) having a liquid crystal display D as an electronic display, and is used as a viewer and a viewfinder. The liquid crystal display D may be an organic EL.

  The digital stereo camera is equipped with two lenses and two image sensors, but with three lenses and three image sensors, the distance between the optical axes of the photographic lenses can be changed according to the distance to the subject. It may be anything.

As shown in FIG. 2, the pair of stereo images SR and SL are displayed so as to be projected on the reference dimension display screen S. Here, the “reference dimension display screen S” refers to a position where the visual field of the observer viewing the stereo images SR and SL matches. In the display image W1 between the pair of stereo images SR and SL, the observer's pupil interval is B, the distance from the pupil to the liquid crystal display D is L1, and the distance from the observer's pupil to the reference dimension display screen S is L0. ,
It is set by the relational expression of W1 = B (1-L1 / L0).

  Therefore, the pair of stereo images SL and SR only need to be displayed on the liquid crystal display D at a distance of the display interval W1, and as shown in FIG. 3, the pair of displays separated from each other on the liquid crystal display D by the display interval W1. The windows WR and WL may be provided, and the stereo images SR and SL may be displayed on the display windows WR and WL, respectively. For example, if the distance L0 from the pupil to the reference dimension display screen S is 2500 mm, the reference dimension display screen width W0 is 1800 mm, and the width W2 of the display windows WR and WL is 55 mm, the distance L1 from the pupil to the liquid crystal display D is 1800. /55=32.7272 2500 / 32.7272 = 76.39 (mm), which is 76.39 mm.

The focal length of a later-described viewer lens (a pair of left and right loupes) 20 is theoretically 76.39 mm, but 70 to 80 mm may be used. This is because the user's diopter is adjusted, and depending on the user's diopter, if further correction is required (if the diopter is extremely far from the standard value, a loupe with a focal length outside the above range is required. It may be better to use it). Moreover, when the pupil interval B of the observer is 65 mm, the display interval W1 between the pair of stereo images SR and SL is
From the above relational expression, W1 = B (1-L1 / L0) = 65 (1-76.39 / 2500) = 63.01 mm.

  Further, the collimation pattern P may be arbitrarily displayed on the display windows WR and WL so as to overlap the stereo images SR and SL. Thereby, the composition of the subject can be easily confirmed after shooting. When used as a finder of a stereo camera, the distance at which the stereoscopic image of the collimation pattern P can be seen is a position where the left and right fields of view coincide with each other.

  However, since this 2500 mm is a set value, it is not limited to this. When taking a stereo photograph, it should be taken so that a stereoscopic image of the subject can be seen beyond the collimation pattern. If the stereoscopic image of the subject is seen on the near side of the stereoscopic image of the collimation pattern, the collimation pattern appears to be doubly shifted. Even if the stereoscopic image of the subject is seen in front of the collimation pattern, if the collimation pattern in the background does not appear to be shifted, it is within the range that can be photographed.

  Further, the aspect ratio of the display windows WR and WL may be arbitrarily changed. In particular, by changing the height H while keeping the width W2 of the display windows SR and SL constant, the display interval W1 between the pair of stereo images SR and SL can be kept constant before and after the aspect ratio change. .

  Further, as shown in FIG. 4, a data display window WD for displaying shooting data such as the resolution of stereo images SR and SL displayed at the time of shooting and after shooting and editing data is displayed on the display windows WR and WL of the liquid crystal display DS. It is preferable to display in the area excluding. Thereby, it is avoided that the shooting data or the editing data is displayed on the stereo images SR and SL, and the stereo images SR and SL are easy to see.

  The collimation patterns displayed on the left and right screens are inevitably necessary for shooting, but they can be annoying (depending on the photographer's preference), so they are displayed only when attached to the camera and shooting as a stereo viewfinder. The display may be switched on / off with a push button or the like, or may be displayed with a timer for a few seconds only when the shutter button is pressed halfway. Further, a collimation pattern may be displayed for inspection when used as a stereo viewer. However, in general, a collimation pattern is displayed during shooting, and is not displayed when used as a stereo viewer.

  Next, the structure of the stereo viewer / stereo viewfinder 1 according to the present embodiment will be described with reference to FIG. The stereo viewer / stereo viewfinder 1 includes a light shielding hood 10 mounted on the liquid crystal display D and a pair of loupes 20 that can be deployed in parallel to the liquid crystal display D.

  The light shielding hood 10 is composed of a front wall portion 11, a rear wall portion 12, a left wall portion 13, and a right wall portion 14 that are provided upright along the periphery of the rectangular liquid crystal display D. As will be described later, it can be folded. A lower portion of the front wall portion 11 is fixed to the hood frame 15 so as to be rotatable around the rotation axis A1. The left wall portion 13 is configured to be bent inward at a central hinge portion 13a. Moreover, the right side wall part 14 is comprised by the center hinge part 14a so that it can be bent inside.

  The light shielding hood 10 may be detachable from the liquid crystal display D or may be attached to the liquid crystal display D integrally.

  The loupe 20 includes a pair of lenses 21R and 21L and a lens holder 22 that houses the pair of lenses 21R and 21L.

  The pair of lenses 21R and 21L are arranged in the lens holder 22 so that the distance between the optical axes of the lenses 21R and 21L is equal to a general observer's pupil interval B (for example, 65 mm).

  The lens holder 22 is attached to the front inner wall 11a of the light shielding hood 10 via the hinge part 23, and can be rotated by 90 ° around the rotation axis A2 of the hinge part 23. The loupe 20 can be developed substantially parallel to the liquid crystal display D by lifting the lens holder 22 from the front inner wall surface 11a by approximately 90 °. Note that reference numeral 23 a in FIG. 1 is a knob for rotating the lens holder 22.

  Next, the folding procedure of the light shielding hood 10 will be described with reference to FIGS. In FIGS. 5 and 6, the loupe 20 is omitted.

  As shown in FIG. 5, the light shielding hood 3 folds the left wall portion 13 and the right wall portion 14 in substantially half, and slides on the hood frame 15 with the rear wall portion 12 facing the front wall portion 11. The light shielding hood 10 can be folded compactly by tilting the front wall portion 11 inward.

  Further, as shown in FIG. 6, when the light shielding hood 10 is raised, the front wall portion 11 is lifted up, and the left side of the shading hood 10 is lifted by the force of a torsion coil spring (not shown) installed in the central hinge portions 14a and 15a. The side wall part 13 and the right side wall part 14 spread, and the light shielding hood 10 can be easily developed.

  In this way, the stereo viewer / stereo viewfinder 1 according to the present embodiment prevents the intrusion of outside light into the liquid crystal display D when the stereo image is photographed or viewed outdoors. The stereo images SR and SL displayed on the liquid crystal display D are easily visible. In addition, when the hood is stored, the light-shielding hood 10 can be folded small and carried easily.

  Next, a stereo viewer / stereo viewfinder according to a second embodiment of the present invention will be described with reference to FIG. Here, the description common to the stereo viewer / stereo viewfinder according to the present embodiment and the stereo viewer / stereo viewfinder according to the first embodiment described above is omitted.

  The stereo viewer / stereo viewfinder 1 includes a loupe lifting mechanism X that can lift and lower the loupe 20 in a vertical direction V perpendicular to the liquid crystal display D.

  The loupe elevating mechanism X has a column 16 fitted in a U-shaped slit 11b formed in the center of the front inner wall surface 11a along the vertical direction V and a side end portion 16a of the column 16 along the vertical direction V. An extended worm screw 17 and an input gear 18 that meshes with the worm screw 17 are provided.

  The column 16 is connected to the loupe 20 via the hinge portion 23. Specifically, the upper end portion 22 a of the lens holder 22 is connected to the upper end 16 b of the column 16 via the hinge portion 23.

  The column 16 is provided independently of the front wall 11, can move up and down in the vertical direction V in the slit 11 b, and can rise above the front wall 11 in the vertical direction V. That is, in addition to the height of the upper end of the front wall portion 11 (for example, 50 mm), the liquid crystal display D and the loupe are equivalent to the length of the column 15 protruding upward from the upper end of the front wall portion 11 (for example, 15 mm). 20 can be separated. Thereby, the loupe 20 can be raised to an installation distance (for example, 65 mm) longer than the height of the light shielding hood 10.

  In the middle of the paragraph [0051], “... 70 to 80 mm may be used.”, And the above “… the distance longer than the height of the light shielding hood 10 (for example, 65 mm)” Although it seems to be contradictory, in reality, the distance between the object and the loupe when looking into the loupe is slightly shorter than the focal length of the loupe.

  A support arm 16 c protrudes from the upper and lower portions toward the horizontal direction H perpendicular to the vertical direction V from the side end portion 16 a of the column 16.

  The worm screw 17 includes a worm shaft 17a rotatably supported on the support arm 16c, and a worm 17b formed on the peripheral surface of the worm shaft 17a. The worm screw 17 rotates around the worm shaft 17 a in conjunction with the rotation of the input gear 18. It moves up and down in conjunction with the rotation of the worm screw 17.

  At the upper end of the worm shaft 17a, there is provided a fine adjustment knob 17c which is attached integrally with the worm shaft 17a and rotates the worm screw 17 around the worm shaft 17a.

  The input gear 18 is pivotally supported by a rotating shaft 18a protruding from the front inner wall 11a. For example, a worm wheel or a helical gear is used as the input gear 18.

  The input gear 18 has a protruding portion 18 b that protrudes outward from the front wall portion 11. The observer can rotate the input gear 18 around the rotation shaft 18 through the protruding portion 18b.

  In the tooth groove of the input gear 18, an elevator stopper (not shown) that prevents the worm 17b and the input gear 18 from meshing with each other is provided. When the worm 17b meshes with the tooth groove provided with the lift stopper, the rotation of the worm screw 17 is stopped. Reference numeral 18 c is a marker indicating the position where the elevation stopper is arranged, that is, the rotation limit position of the input gear 18.

  The raising / lowering stopper only needs to interfere with the meshing between the worm 17b and the input gear 18. For example, even if the raising / lowering stopper is formed by attaching a metal piece to the tooth gap and filling the tooth gap, Even if it is formed by welding metal pieces and filling the tooth gap, it may be formed by leaving one tooth gap without being cut at the time of gear cutting.

  Next, the operation of the loupe lifting device 20 that lifts and lowers the loupe 20 will be described based on the drawings.

  When the observer raises the loupe 20, the projecting portion 18b of the input gear 18 is rotated clockwise around the rotation shaft 18a. When lowering the loupe 20, the protruding portion 18b of the input gear 18 is rotated counterclockwise around the rotation shaft 18a. In addition, since the raising / lowering of the loupe 20 can be switched by changing the rotation direction of the input gear 18 described above, a case where the loupe 20 is raised will be described below.

  The worm 17 b meshes with the input gear 18, and the worm screw 17 rises upward in the vertical direction V in conjunction with the rotation of the input gear 18.

  If the column 16 continues to rise until the distance between the loupe 20 and the liquid crystal display D coincides with the focal length of the loupe 20, a lift stopper is interposed between the worm 17 b and the input gear 18, and the worm screw 17 is rotated. The column 16 and the loupe 20 are positioned.

  Therefore, since the elevating stopper can be arranged according to the focal length of the loupe 20 and the diopter of the observer, the diopter can be easily adjusted and the loupe 20 can be fixed.

  Further, by slightly rotating the worm screw 17 via the fine adjustment knob 17c, the column 16 and the loupe 20 are slightly raised and lowered, so that the position of the loupe 20 with respect to the liquid crystal display D can be finely adjusted.

  In this way, the stereo viewer / stereo viewfinder 1 according to the present embodiment can adjust the diopter of the loupe 20 in addition to the effects produced by the stereo viewer / stereo viewfinder of the first embodiment.

  As shown in FIG. 8, the loupe elevating mechanism X includes a column 16, a stopper hole 16d provided in the lower portion of the column 16, and a stopper pin that is inserted through the stopper hole 16d and positions the column 16 at a desired position. 16e. Thereby, after raising the column 16 to a desired position, the column 16 can be positioned only by inserting the stopper pin 16e into the stopper hole 16d, so that the loupe lifting mechanism X can be provided at low cost.

  Further, as shown in FIG. 9, the light shielding hood 10 has a slide holder 19 disposed below the hood frame 15, and the hood frame 15 and the slide holder 19 form a slot 19 a into which the silver salt stereo slide SS is inserted. The liquid crystal display D may display white as the backlight of the silver salt stereo slide SS. Since the distance between the observer's pupil and the silver salt stereo slide SS is shorter than the distance between the observer's pupil and the liquid crystal display D, the diopter is adjusted by raising and lowering the loupe 20 to V in the vertical direction. A person can arbitrarily select the silver salt stereo slide SS and the liquid crystal display D.

  This is one of the features of the present invention. That is, diopter adjustment varies from individual user to individual user and therefore needs to be adjustable to different values for each individual user. At the same time, for example, when used by the same user, the diopter adjustment is always at a fixed position. The structure shown in FIG. 7 includes the elements.

  Further, it is necessary to change the focus adjustment between when viewing a liquid crystal display and when viewing a silver salt stereo photograph, but this adjustment can be handled only by turning the fine adjustment knob 17c of FIG.

  Once adjusted, the adjusted position is adjusted to a fixed position during use. Although not shown, for example, a stopper is pressed against the groove on the outside of the fine adjustment knob 17c with a spring or the like to provide a so-called click stop mechanism, or resistance to rotation so that it does not rotate easily. If attached, the adjustment position is always reproduced at a fixed position.

  In FIG. 9, when the silver salt stereo slide SS is inserted into the slot 19a, a discharge lever 19b for placing the silver salt stereo slide SS may be provided. Thereby, silver salt stereo slide SS can be taken in and out easily. In addition, when a liquid crystal display is displayed in white and used as a backlight, a black line between liquid crystal pixels may be noticeable. If this black line is conspicuous when looking at the silver salt stereo slide, there is a problem that the image quality is remarkably lowered.

  Therefore, it is to insert a diffuser for scattering light rays. The diffuser may simply be a white film-like sheet, and two sheets may be inserted simultaneously with the stereo slide, but should be fixed in some way when viewing the stereo slide (not shown). It is recommended to keep the fuser and stereo slide as far apart as possible.

  Next, a stereo slide viewer / stereo viewfinder according to a third embodiment of the present invention will be described with reference to FIGS. Here, the description common to the stereo viewer / stereo viewfinder according to the present embodiment and the stereo viewer / stereo viewfinder according to the first embodiment described above is omitted.

  The stereo viewer / stereo viewfinder 1 includes a partition plate 30 that partitions the field of view of the pair of lenses 21R and 21L.

  The support side end 30a of the partition plate 30 is attached to the rear inner wall surface 12a facing the front inner wall surface 11a via a hinge portion (not shown), and the partition plate 30 is a rotation axis perpendicular to the liquid crystal display D. It can rotate around A3. Further, the partition-side end 30a of the partition plate 30 is provided with a biasing force in the clockwise direction of the paper surface in the direction in which the partition plate 30 is unfolded, that is, around the rotation axis A3 in FIG. It is working.

  The rotation side end 30b of the partition plate 30 is positioned in a state parallel to the vertical direction V and is hooked by a rotation stopper 40 slidable in the horizontal direction H. It is fixed to the unit.

  The rotation stopper 40 includes an L-shaped hook portion 41 that passes through the insertion hole 12b formed in the rear wall portion 12 of the light shielding hood 10 and is hooked to the rotation end side portion 30b of the partition plate 30 at the tip. A U-shaped spring 42 that attaches the hook portion 41 from the outside in the horizontal direction H to the inside; and a guide portion 43 that is tapered at the tip of the hook portion 41 from the outside in the horizontal direction H to the inside. It is equipped with.

  Next, a procedure for expanding the partition plate 30 will be described.

  When the hook part 41 slides from the inner side in the horizontal direction H to the outer side in the insertion hole 12b in a state where the loupe 20 is deployed in parallel with the liquid crystal display D, the latching of the partition plate 30 and the hook part 41 is released. The partition plate 30 is rotated around the rotation axis A3.

  The partition plate 30 is rotated until the biasing force of the torsion coil spring abuts the rotation side end 30b of the partition plate 30 against the stopper pin 11c provided below the loupe 20, and the partition plate 30 is moved to the front inner wall surface 11a. And the rear inner wall surface 12a.

  Next, a procedure for fixing the partition plate 30 to the rear inner wall surface 12a will be described.

  When the rotation side end 30b of the partition plate 30 is rotated to the guide portion 43 of the rotation stopper 40, the partition plate 30 attaches the hook portion 41 of the U-shaped spring 42 from the outside in the horizontal direction H to the inside. The hook portion 41 is slid from the inside in the horizontal direction H to the outside while resisting the attachment.

  When the partition plate 30 comes close to the rear inner wall surface 12a until the rotation-side end portion 30a of the partition plate 30 and the guide portion 43 of the rotation stopper 40 are separated from each other, the hook portion 41 is moved by the force of the U-shaped spring 42. Then, it slides inward from the outside in the horizontal direction H and is hooked on the rotation side end portion 30b of the partition plate 30, and the partition plate 30 is fixed to the rear inner wall surface 12a.

  In this way, the stereo viewer / stereo viewfinder 1 according to the present embodiment has the partition plate 30 for the pair of stereo images SR and SL in addition to the effects produced by the stereo viewer / stereo viewfinder 1 of the first embodiment. By partitioning the field of view, the pair of stereo images SR and SL can be easily viewed stereoscopically. Further, the partition plate 30 can be opened and closed according to the time when the light shielding hood 10 is deployed and stored.

  Next, a stereo viewer / stereo viewfinder according to a fourth embodiment of the present invention will be described with reference to FIGS. Here, the description common to the stereo viewer / stereo viewfinder according to the present embodiment and the stereo viewer / stereo viewfinder according to the first embodiment described above is omitted.

  The loupe 20 mounts a pair of lenses 21R and 21L, a pair of lens holders 22R and 22L for accommodating the lenses 21R and 21L, and a pair of lens holders 22R and 22L. And a support base 24 connected to each other.

  The pair of lens holders 22R and 22L are pivotally supported by pins 25R and 25L protruding from the support base 24, respectively. The distance between the pins 25R and 25L is set to 65 mm, and the distance between the optical axes of the pair of lenses 22R and 22L (hereinafter referred to as “lens distance”) is usually equal to the distance between the pins 25R and 25L. It is set to 65 mm.

  The pins 25R and 25L are disposed above the pair of lenses 22R and 22L, respectively. Note that the specific arrangement positions of the pins 25R and 25L may be any distance as long as the distance between the lenses can be adjusted, and the pins 25R and 25L are connected to each other except for a straight line connecting the centers of the pair of lenses 22R and 22L. As long as the straight lines are arranged so as to be parallel to the straight lines connecting the centers of the lenses 22R and 22L, they may be located anywhere.

  The inter-lens distance adjusting mechanism Y that can adjust the inter-lens distance between the pair of lenses 21R and 21L can be engaged with the pair of lens holders 22R and 22L and the facing surface 22b of the pair of lens holders 22R and 22L. Segment gears 26R and 26L formed.

  Accordingly, when the lens holders 22R and 22L are rotated so that the pair of lenses 21R and 21L are close to each other, the distance between the lenses is narrowed, and the pair of lenses 21R and 21L are separated from each other. Since the distance between the lenses increases as the lens rotates, the distance between the pair of lenses 21R and 21L can be adjusted according to the eye width of the observer.

  Further, when the lens holders 22R and 22L are rotated, the segment gears 26R and 26L are engaged with each other, so that the lens holders 22R and 22L are rotated in conjunction with each other, thereby reducing the work burden associated with the adjustment of the distance between the lenses. can do.

  The inter-lens distance adjusting mechanism Y includes a rotation stopper 27 for restricting the rotation of the lens holders 22R and 22L. The over rotation stopper 27 includes an over approach stopper 27a that prevents the pair of lens holders 22R and 22L from excessively approaching, and an over separation stopper 27b that prevents the pair of lens holders 22R and 22L from excessively separating from each other. It is equipped with.

  The excessively approaching stopper 27a is a protruding piece protruding from the opposing surface 22b at the rear of the lens holders 22R and 22L, and is formed integrally with the lens holders 22R and 22L. The over approach stopper 27a is disposed so that the over approach stoppers 27a come into contact with each other when the distance between the lenses reaches a predetermined lower limit value (for example, 58 mm). The specific arrangement position and length of the over approach stopper 27a are arbitrarily set according to the lower limit value of the inter-lens distance.

  The over-spaced stopper 27b is a pin that is disposed on a support base and is disposed in a cutout portion 22c in which a part of the facing surface 22b of the lens holders 22R and 22L is cut out in a rectangular shape. The over-spaced stopper 27b is disposed so as to contact the over-spaced stopper 27b on the inner peripheral surface 22d of the notch portion 22c when the lens interval reaches a predetermined upper limit (for example, 72 mm). The arrangement position and size of the over-spaced stopper 27b are arbitrarily set according to the upper limit value of the inter-lens distance.

  Thereby, the excessive rotation stopper 27 can suppress the excessive rotation of the lens holders 22R and 22L, and can smoothly adjust the inter-lens distance between the pair of lenses 21R and 21L within a desired range.

  In this way, the stereo viewer / stereo viewfinder 1 according to the present embodiment has an inter-lens distance according to the pupil distance of the observer, in addition to the effects produced by the stereo viewer / stereo viewfinder 1 of the first embodiment. Can be adjusted.

  Next, a fifth embodiment will be described. The pair of left and right lens units 50 displayed in FIGS. 14 a, b, and c are different embodiments from the stereo viewer / stereo viewfinder 1 displayed in FIG. 12, and the display D other than the lens unit, the light shielding hood 10, The column 16 and the like are common to FIG.

  In the lens unit 50 shown in FIG. 14 a, a base plate 240 is attached to the lower portion of the lens unit 50 so as to be rotatable by 90 ° with respect to the display D. The left and right lower portions of the base plate 240 are provided with holes (without symbols) of left and right fulcrum pins 54R and 54L to which lens holders 52R and 52L described later are attached and swiveled. In addition, holes 53R and 53L larger than the lens are formed so that the lens 51R and 51L overlap with each other so that the lens holders 52R and 52L do not interfere even when the lens holders 52R and 52L are swiveled.

  That is, the left and right lens holders 52R and 52L are mounted on the base plate 240 by the left and right pins 54R and 54L so as to be rotatable around the respective pins 54R and 54L. The left and right lens holders 52 </ b> R and 52 </ b> L are applied with a force in a direction in which they approach each other by a spring 57.

  Further, a cam shaft 56 is inserted into a hole (not shown) formed in the base plate in the middle portion in the left and right direction of the left and right lens holders 52R and 52L, and the cam shaft 56 includes a cam 55R and a cam 55L. Is attached, and finally the interval between the left and right lenses 51R and 51L is adjusted by turning the head of the camshaft 56 with a finger.

  FIG. 14B is a partial cross-sectional view centering on the camshaft 56, showing a state where the cam 55R pushes the end surface of the lens holder 52R, and a state where the cam 55L pushes the lens holder 52L. The cams 55R and 55L are actually very thin, about 1 mm, and it is better to attach the washer 58 of FIG. The washer 58 can be pressed into the shaft and rotated together.

  FIG. 14C is an example showing an assembled state of the camshaft 56, the cam 55R, and the cam 55L. The camshaft 56 is a key for maintaining the position of the cam 55R and the cam 55L in the rotational direction with respect to the camshaft 56. A groove is formed. Two key grooves may be provided, but it is necessary to accurately determine the provision of two grooves, and even for a small shaft, the groove must be formed by machining and requires a lot of labor. It is advantageous to have a groove in the book.

  Since the cams 55R and 55L punch out the outer shape and the hole with a press (thickness of about 1 mm), even if the positions of the portions that fit into the key groove with respect to the hole are 55R and 55L opposite to each other, it does not matter much. It is. In addition, the outer shapes of the cams 55R and 55L seem to be only the same cam rotated by 180 °, but the end surfaces of the lens holder 52R and the lens holder 52L are not parallel, so that the cam with the same profile is changed by changing the contact angle. Two kinds of cams need to be made because they cannot be used.

  In addition, the adjustment of the distance between the left and right lenses may not necessarily be the same. In that case, the same left and right cams can be used.

  Note that the left and right cams cause a step between the left and right in the thickness direction. Therefore, the lens holders 52R and 52L contacting the cams 55R and 55L also need a step, but the lens holder 55 has a thickness of about 1 mm and the cam has a thickness of about 1 mm. The end surface of the lens holder 55 may be bent at the cam position on the upper side.

  Further, a light shielding hood 60 as shown in FIG. 15 is also used for an ordinary camera. When the light shielding hood 60 is folded, the left and right side walls 63 and 64 are folded in either the left or right order, then the rear side wall 67 is folded, and finally the front side wall 61 is folded. Although this shading hood 60 is somewhat difficult to use, the cost is low and it is economical and advantageous.

  The light-shielding hood displayed in FIG. 15 is another example, and unlike the light-shielding hoods shown in FIGS. 5 and 6, it cannot be opened and closed with one touch. When the shading hood of FIG. 15 is opened, first the front lid 61 is opened, then the rear lid 62 is opened, and then the horizontal lid 63 or 64 is opened in that order. Further, when the illustrated light shielding hood is closed, the horizontal lid 63 or 64 is sequentially closed in the reverse order to the opening, and then the rear lid 62 is closed and the front lid 61 is closed. As described above, the opening and closing takes more time than the shading hood shown in FIG.

  Although not shown in the drawing, the shading hood shown in FIG. 15 has the loupe 20 shown in FIG. 1 and the display (pattern) shown in FIG. 3, the second embodiment shown in FIG. Stereo Camera 2 FIG. 16 is a diagram when the stereo viewfinder 1 is attached to the stereo camera 2 and used. The display has a structure that can be rotated 90 ° in the upper row, and the illustration shows 90 ° in the direction of the arrow. It is a case where it rotates.

  FIG. 17 shows an example of a structure in which the stereo viewfinder 1 is attached to the stereo camera 2, and holes 72 and 73 provided in the display are used as attachment holes. The hole 73 provided in the display is merely provided on the side of the display, but the hole 72 is provided in the center of the face coupling 78 (or may be a hole of the face coupling). 73 can be attached simply by pinching it with pins 74 and 75 provided on the camera side.

  The length of the screw 80 is adjusted so that the front end of the screw has a slight gap more than the maximum length when the face couplings 77 and 78 are rotated. If it is only attached, only the screw 80 may be used, but it is necessary to pressurize with the coil spring 79 in order to exert the click action effect. Further, since the pin 75 jumps out of the pin moving hole 83 by the coil spring 79, the pin moving part 76 prevents the popping out by the pin moving part 76, and the pin moving part 76 actually removes the stereo viewfinder 1 from the stereo camera 2. When removing, the pin 75 is advanced by the coil spring 79, so there is no clue to retract the pin 75.

  Therefore, the pin moving part 76 is also required. If it is merely an action, the screw 80 is unnecessary. However, if the pin moving part 76 is inadvertently moved, the stereo viewfinder 1 will fall from the stereo camera 2 instantly. The screw 80 is absolutely necessary to prevent the fall.

  In addition, the coupling 77 is press-fitted into a pin 74 provided on the camera side (in FIG. 17b, a “step” is added to the cross-sectional shape. (Good) And the position in the rotational direction is positioned by the coupling positioning pin. At this time, the coupling 78 on the display side is integrally molded and positioned in advance. And since the front-end | tip of the pin 74 provided in the camera side and the hole of the coupling 78 are a loose fitting state, it can attach easily even if it is a little slanting state. Therefore, if the screw 80 is loosened and the pin moving screw 76 is moved to the right, the tip of the pin 75 is retracted from the left end surface of the pin moving hole 83, so that the display D can be attached.

  Further, face couplings 77 and 78 are provided so that the display D and the light shielding hood 1 do not descend due to gravity or the like. In the face coupling mechanism, the coil spring 79 always acts via the pin 75. Furthermore, the camera body 2 and the display D themselves are stoppers in the lower limit direction of rotation, and the upper limit value is a position opened by 90 ° (not limited to 90 °), and the stopper 82 acts on the limit position. To do. Since the face couplings 77 and 78 act and attempt to rotate 90 ° or more, the rotation is restricted by the vertical stopper, and the display can be prevented from rotating unintentionally (swivel) during storage. effective.

  Although not shown in the figure, a removable memory should be provided on the display side or connected so that it can be removed from the camera and used as a stereo viewer. Moreover, it should be configured so that a battery or an external power source can be used, and the display drive mechanism should be provided on the stereo viewer side (display side).

  The electronic apparatus to which the stereo viewer and the stereo view finder according to the present invention are applied may be any electronic device provided with an electronic display capable of displaying a stereo image, for example, a mobile phone, a digital camera, an image It may be a generation device.

  The present invention can be variously modified without departing from the spirit of the present invention, and the present invention naturally extends to the modified ones.
