The present invention achieves the purpose of facilitating the visual inspection of a stereoscopic image displayed on an electronic display and facilitating the transportation of the stereoscopic image, and is realized by the following configuration, that is, a stereoscopic image detector and/or a stereo viewfinder. An electronic device having an electronic display for displaying a pair of stereoscopic images, comprising: a hood mounted on the electronic display and foldable; and a magnifying glass provided with a pair of lenses for viewing the stereoscopic image and via the hinge portion It is attached to the inner wall portion of the hood and can be deployed in parallel with respect to the electronic display.

[Examples]

Hereinafter, a stereo camera/stereoscopic viewfinder according to a first embodiment of the present invention will be described with reference to Figs. 1 to 6 .

As shown in FIG. 1, the stereo camera/stereo viewfinder 1 is applied to a digital stereo camera (not shown) including a liquid crystal display D as an electronic display, and is used as an image detector and a viewfinder. Further, the liquid crystal display D may also be an organic EL.

The digital stereo camera may be provided with two lenses and an imaging element, or three lenses and an imaging element, and the distance between the optical axes of the imaging lens may be changed depending on the distance from the subject.

As shown in FIG. 2, a pair of stereoscopic images SR and SL are displayed so as to be projected on the standard scale display screen S. Here, the "standard scale display screen S" refers to a position at which the observer's field of view of the stereoscopic images SR and SL is identical. The display interval W1 between the pair of stereoscopic images SR and SL is set to B at the observer's eye interval, the distance from the eye to the liquid crystal display D is L1, and the distance from the observer's eye to the standard-scale display screen S is set to At L0, it is set according to the relational expression of W1=B(1-L1/L0).

Therefore, the pair of stereoscopic images SL and SR may be displayed on the liquid crystal display D so as to be separated from each other by the display interval W1. As shown in FIG. 3, the liquid crystal display D is provided with a degree that is separated from each other by the display interval W1. For the display windows WR and WL, the display windows WR and WL can also display the stereoscopic images SR and SL. For example, the distance L0 from the eye to the standard scale display screen S is set to 2500 mm, the standard scale display screen width W0 is set to 1800 mm, and when the width W2 of the display windows WR and WL is 55 mm, the distance L1 from the eye to the liquid crystal display D is obtained. It is 1800/55=32.7272 2500/32.7272=76.39 (mm) and becomes 76.39 mm.

Further, the focal length of the lens (left and right pair of magnifiers) 20 of the image sensor described later is theoretically 76.39 mm, but it is also possible to use 70 mm to 80. In order to adjust the user's visibility, it is necessary to re-correct according to the user's visibility (there is also a case where the person whose visibility is extremely deviated from the standard value is better than the magnifying glass which is the focal distance outside the above range). Further, when the eye interval B of the observer is set to 65 mm, the display interval W1 between the pair of stereoscopic images SR and SL becomes W1=B(1-L1/L0)=65 (1-76.39/2500 according to the above relational expression). ) = 63.01mm.

Further, the collation pattern P may be superimposed on the stereoscopic images SR and SL and arbitrarily displayed on the display windows WR and WL. Thereby, whether it is during photography or after photography The composition of the subject can be easily confirmed. When it is used as a viewfinder of a stereo camera, the distance of the stereoscopic image of the sight pattern P can be seen at a position where the left and right visual fields coincide, so that it can be seen at a distance of 2500 mm.

However, since this 2500 mm is a set value, it is not limited by this. In the case of photographing a stereoscopic photograph, a stereoscopic image of the subject should be photographed on the opposite side of the collimated pattern. If the stereoscopic image of the subject is visible near the front side of the stereoscopic image of the collimated pattern, the collimated pattern seen becomes a double image. Even if the stereoscopic image of the subject is seen on the front side closer to the collimated pattern, if the collimated pattern of the back image is not seen, it is a good range that can be photographed.

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

Moreover, as shown in FIG. 4, the data display window WD for displaying the photographic data or the compiled material for displaying the resolution of the stereoscopic images SR, SL displayed at the time of shooting or after shooting is preferably displayed in the liquid crystal display D. Except for the display windows WR, WL. Thereby, when the photographic data or the edited material is overlapped and displayed on the stereoscopic images SR and SL, the stereoscopic images SR and SL are easily seen.

In addition, although the collimated pattern displayed on the left and right screens is required for photography anyway, it can be made to be attached to the camera only when used as a stereo viewfinder in the case of being boring (depending on the photographer's preference). Display, press the button or the like to switch ON/OFF and display, or display the timer for a few seconds only when the shutter button is pressed halfway. Further, when used as a stereo camera, it is also possible to display a collimation pattern for inspection. However, it is generally displayed in the sight pattern during shooting, and it is not necessary to display it when used as a stereo camera.

Next, the configuration of the stereo camera/stereo viewfinder 1 of the present embodiment will be described with reference to Fig. 1. The stereo camera/stereo viewfinder 1 includes a hood 10 attached to the liquid crystal display D and a pair of magnifiers 20 that are expandable in parallel with the liquid crystal display D.

The 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 which are respectively erected along the periphery of the rectangular liquid crystal display D, and the hood 10 is foldable as will be described later. . The lower portion of the front wall portion 11 is rotatably fixed to the hood frame 15 about the rotation axis A1. The left wall portion 13 may be configured to be bendable inward at the center hinge portion 13a. Further, the right wall portion 14 is configured to be bendable inside the center hinge portion 14a.

In addition, the hood 10 may be detachably attached to the liquid crystal display D or may be mounted integrally with the liquid crystal display D.

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

The pair of lenses 21R and 21L are disposed in the lens holder 22 such that the distance between the optical axes of the lenses 21R and 21L is equal to the general eye interval B (for example, 65 mm) of the observer.

The lens holder 22 is attached to the front inner wall 11a of the shade 10 via the hinge portion 23, and is rotatable by 90° about the rotation axis A2 of the hinge portion 23. By moving the lens holder 22 substantially 90 degrees from the front inner wall surface 11a, the magnifying glass 20 can be expanded substantially in parallel with the liquid crystal display D. Further, reference numeral 23a in Fig. 1 is a knob that rotates the lens holder 22.

Next, the folding procedure for the hood 10 will be described with reference to Figs. In addition, in FIGS. 5 and 6, the magnifying glass 20 is omitted.

As shown in FIG. 5, the hood 10 is formed by the left wall portion 13 and The right wall portion 14 is substantially folded in half, and the rear wall portion 12 is slid toward the front wall portion 11 while being slid on the hood frame 15, and the front wall portion 11 is inverted inside, whereby the hood 10 can be folded compactly.

Further, as shown in Fig. 6, when the hood 10 is activated, only the front wall portion 11 is lifted up, and the left-hand hinge portion 13a, 14a is provided with a potential of a torsion coil spring (not shown). The square wall portion 13 and the right wall portion 14 are expanded to easily expand the hood 10 .

As described above, the stereoscopic viewer/stereoscopic viewfinder 1 of the present embodiment is configured to prevent external light from entering the liquid crystal display D and to be easily displayed on the liquid crystal display D when photographing or appreciating a stereoscopic image outside the room. Stereo images SR, SL. Moreover, when the hood is taken up, the hood 10 is folded down and can be easily transported.

Next, a stereo camera/stereo viewfinder according to a second embodiment of the present invention will be described with reference to Fig. 7 . Here, the configuration in which the stereoscopic imager/stereoscopic viewfinder of the present embodiment is common to the stereoscopic imager/stereoscopic viewfinder of the above-described first embodiment will not be repeatedly described.

The stereo camera/stereo viewfinder 1 is provided with a magnifying glass elevating mechanism X that allows the magnifying glass 20 to be raised and lowered in a vertical direction V perpendicular to the liquid crystal display D.

The magnifying glass elevating mechanism X includes a cross section that is formed in the center of the front inner wall surface 11a along the vertical direction V. a column 16 of the word slit 11b; a worm thread 17 extending in the vertical direction V at the side end portion 16a of the column 16; and an input gear 18 meshing with the worm thread 17.

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

The column 16 and the front wall portion 11 are provided independently, and are vertically movable in the vertical direction V in the slit 11b, and are more likely to rise above the vertical direction V than the front wall portion 11. That is, in addition to the height (for example, 50 mm) of the upper end of the front wall portion 11, the length of the column 16 (for example, 15 mm) which protrudes upward from the upper end of the front wall portion 11 is added, and the liquid crystal display can be made. D is alienated from the magnifying glass 20. Thereby, the magnifying glass 20 can be raised to a set distance (for example, 65 mm) longer than the height of the hood 10.

In addition, in the middle of the aforementioned paragraph [0051], it is mentioned that "...the use of 70mm~80 is no problem....", and the above mentioned "...the distance longer than the height of the hood 10 (for example, 65mm).. . . . , 乍 seems to think that there is a contradiction, but that is because the distance between the object and the magnifying glass in the case of actually looking at the magnifying glass is slightly shorter than the focal distance of the magnifying glass.

At the side end portion 16a of the column 16, a support arm 16c is protruded from the upper portion and the lower portion in a horizontal direction H perpendicular to the vertical direction V.

The worm thread 17 is provided with a worm shaft 17a rotatably supported by the support arm 16c and a worm 17b formed on the circumferential surface of the worm shaft 17a. The worm thread 17 is rotated about the worm shaft 17a in conjunction with the rotation of the input gear 18, and is raised and lowered in conjunction with the rotation of the worm thread 17.

At the upper end of the worm shaft 17a, a fine adjustment knob 17c that is integrally attached to the worm shaft 17a and that rotates the worm thread 17 around the worm shaft 17a is provided.

The input gear 18 is pivotally supported by the rotating shaft 18a of the front inner wall 11a. Further, in terms of the input gear 18, for example, a worm wheel or a helical gear or the like is used.

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

An unillustrated elevating limiter that hinders the meshing of the worm 17b and the input gear 18 is disposed in the groove of the input gear 18. When the worm 17b is engaged with the groove provided with the lift limiter, the rotation of the worm thread 17 is stopped. Further, reference numeral 18c denotes a position at which the lift limiter is disposed, that is, a mark indicating the rotational limit position of the input gear 18.

The lifting limiter may be configured to interfere with the engagement of the worm 17b and the input gear 18. For example, a metal piece may be attached to the groove to fill the groove, and the metal piece may be welded to the groove to fill the groove. The former may be formed by leaving a tooth groove without cutting into teeth when cutting the teeth.

Next, the action of the magnifying glass elevating mechanism X for raising and lowering the magnifying glass 20 will be described based on the drawings.

When the observer raises the magnifying glass 20, the protruding portion 18b of the input gear 18 is clocked around the rotating shaft 18a. To lower the magnifying glass 20, the protruding portion 18b of the input gear 18 is rotated counterclockwise about the rotating shaft 18a. Further, since the lifting and lowering of the magnifying glass 20 can change the turning direction of the input gear 18 described above, the case where the magnifying glass 20 is raised will be described below.

The worm 17b is meshed with the input gear 18, and the worm thread 17 is moved in the upward direction of the vertical direction V in conjunction with the rotation of the input gear 18.

When the column 16 continues to rise until the distance between the magnifying glass 20 and the liquid crystal display D coincides with the focal length of the magnifier 20, the lifting limiter is interposed between the worm 17b and the input gear 18, the rotation of the worm thread 17 is stopped, and the column 16 is The magnifying glass 20 is positioned.

Therefore, it is possible to easily adjust the visibility and fix the magnifying glass 20 by arranging the lifting limiter in accordance with the focal length of the magnifying glass 20 and the observer's visibility.

Further, since the worm thread 17 is slightly rotated by the fine adjustment knob 17c, the column 16 and the magnifier 20 are only slightly raised and lowered, so that the position of the magnifier 20 with respect to the liquid crystal display D can be finely adjusted.

As described above, the stereoscopic imager/stereoscopic viewfinder 1 of the present embodiment can adjust the visibility of the magnifying glass 20 in addition to the effect of the stereoscopic imager/stereoscopic viewfinder of the first embodiment.

In addition, as shown in FIG. 8, the magnifying glass lifting mechanism X may also be defined by a column 16, a restrictor hole 16d provided at a lower portion of the column 16, and a limiter pin that is inserted into the restrictor hole 16d to position the column 16 at a desired position. 16e is composed. Thereby, after the column 16 is raised to a desired position, the column 16 can be positioned by inserting the stopper pin 16e into the stopper hole 16d, so that the magnifying glass elevating mechanism X can be provided at low cost.

Further, as shown in FIG. 9, the hood 10 may be such that a slide holder 19 is disposed under the hood frame 15 and a long hole in which the silver salt stereoscopic slide SS is inserted by the hood frame 15 and the slide holder 19 is formed. 19a, the liquid crystal display D is displayed as a backlight of the silver salt stereoscopic slide SS. Since the distance between the observer's eyes and the silver salt stereoscopic slide SS is shorter than the distance between the observer's eyes and the liquid crystal display D, the viewer can arbitrarily adjust the gaze by raising and lowering the magnifying glass 20 in the vertical direction V. Select silver salt stereo slide SS and liquid crystal display D.

This is one of the features of the present invention. That is to say, the gaze adjustment varies depending on each user, so it is necessary to adjust the value to be different for each user. At the same time, for example, when the same user is used, it is necessary to adjust it to a certain amount at any time. The position shown in Fig. 7 has this element.

Further, in the case of viewing the liquid crystal display and the case of viewing the silver salt stereoscopic photograph, it is necessary to change the focus adjustment, but this adjustment can be performed by merely rotating the fine adjustment knob 17c of Fig. 7.

Moreover, if it is adjusted once, its adjustment position will be adjusted to a certain position when it is used. The illustration is omitted. For example, the stopper is held by a spring or the like at the outer groove or the like of the fine adjustment knob 17c, a so-called click stop mechanism is provided, or the resistance is given before the rotation, and it is not easy to rotate, and the position is adjusted. Always appear in a certain position again.

Further, in Fig. 9, a discharge rod 19b may be provided to mount the silver salt stereoscopic slide SS when the silver salt stereoscopic slide SS is inserted into the long hole 19a. Thereby, the silver salt stereoscopic slide SS can be easily taken. Further, when the liquid crystal display is displayed in white as a backlight, black lines between pixels of the liquid crystal may be noticeable. If the black line is conspicuous when viewing the silver salt stereoscopic slide, there is a problem that the image quality becomes very low.

Therefore, a diffuser is inserted to scatter light. The diffuser may be a white sheet-like sheet, and may be inserted into two sheets at the same time as the stereoscopic slide. However, some method of fixing the stereoscopic slide should be fixed in advance (not shown). In addition, the diffuser and the stereo slide can be as far apart as possible.

Next, a stereo camera/stereoscopic viewfinder according to a third embodiment of the present invention will be described with reference to Figs. Here, the configuration in which the stereoscopic imager/stereoscopic viewfinder of the present embodiment is common to the stereoscopic imager/stereoscopic viewfinder of the above-described first embodiment will not be repeatedly described.

The stereo camera/stereo viewfinder 1 is provided with a spacer 30 that partitions the field of view of the pair of lenses 21R and 21L.

The support side end portion 30a of the partition plate 30 is attached to the rear inner wall surface 12a opposed to the front inner wall surface 11a through a hinge portion (not shown), and the partition plate 30 is rotatable about a rotation axis A3 perpendicular to the liquid crystal display D. Further, in the support side end portion 30a of the partition plate 30, the clockwise potential of the paper surface is wound in the direction in which the partition plate 30 is unfolded by the torsion coil spring (not shown) of the hinge portion, that is, the rotation axis A3 in Fig. 10 effect.

The rotation side end portion 30b of the partition plate 30 is in a state parallel to the vertical direction V, and is hooked on the rotation limiter 40 slidable in the horizontal direction H and integrally fixed to the rear wall portion 12 of the hood 10. .

The rotation limiter 40 is provided with an L-shaped hook portion 41 that is inserted into the insertion hole 12b of the rear wall portion 12 of the shade 10 and hooked at the tip end to the rotation side end portion of the partition plate 30. 30b; the U-shaped spring 42 gives a force to the inside of the hook portion 41 from the outer side in the horizontal direction H; and the guide portion 43 which is tapered toward the inner side from the outer side in the horizontal direction H at the front end of the hook portion 41.

Next, a description will be given of a procedure for expanding the spacer 30.

When the magnifying glass 20 is unfolded parallel to the liquid crystal display D, when the hook portion 41 slides from the inner side in the horizontal direction H to the outer side in the insertion hole 12b, the hooking of the partition plate 30 and the hook portion 41 is released. The partition plate 30 is rotated about the rotation axis A3.

The potential of the torsion coil spring causes the partition plate 30 to rotate until the swivel side end portion 30b of the partition plate 30 abuts against the limiter pin 11c provided under the magnifying glass 20, and the partition plate 30 is straddled on the front inner wall surface 11a and the rear side. Between the inner wall faces 12a.

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

When the swivel side end portion 30b of the partition plate 30 is rotated to the guide portion 43 of the swirl limiter 40, the partition plate 30 is such that the hook portion 41 of the U-shaped spring 42 resists the outer side from the horizontal direction H toward The potential of the inner side is caused to slide the hook portion 41 from the inner side in the horizontal direction H to the outer side.

Before the swaying side end portion 30b of the partition plate 30 is separated from the guide portion 43 of the whirl limiter 40, when the partition plate 30 is in close contact with the rear inner wall surface 12a, the hook is made by the potential of the U-shaped spring 42. The portion 41 slides from the outer side in the horizontal direction H to the inner side and is hooked on the swiveling side end portion 30b of the partition plate 30, and the partition plate 30 is fixed in the rear side. Wall 12a.

As described above, in addition to the effect of the stereo camera/stereo viewfinder 1 of the first embodiment, the stereo camera/stereo viewfinder 1 of the present embodiment partitions a pair of stereoscopic images SR, SL by the spacer 30. The field of view makes it easy to obtain stereoscopic vision of a pair of stereoscopic images SR, SL. Further, the partition plate 30 can be opened and closed in response to the deployment of the hood 10 at the time of storage.

Next, a stereo camera/stereoscopic viewfinder according to a fourth embodiment of the present invention will be described with reference to Figs. Here, the configuration in which the stereoscopic imager/stereoscopic viewfinder of the present embodiment is common to the stereoscopic imager/stereoscopic viewfinder of the above-described first embodiment will not be repeatedly described.

The magnifier 20 is connected to the front wall portion via a pair of lenses 21R and 21L, a pair of lens holders 22R and 22L that accommodate the lenses 21R and 21L, and a pair of lens holders 22R and 22L. The support base 24 of 11 is constructed.

The pair of lens holders 22R and 22L are respectively pivotally supported by the pins 25R and 25L protruding from the support table 24. 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 (hereinafter referred to as "inter-lens distance") is usually set to 65 mm which is equal to the distance between the pins 25R and 25L.

The pins 25R and 25L are respectively disposed above the pair of lenses. In addition, the specific arrangement position of the pins 25R and 25L may be a position where the distance between the lenses can be adjusted, and a straight line connecting the pins 25R and 25L and a connecting lens may be used in addition to a linear shape connecting the centers of the pair of lenses. The center line is arranged in a parallel manner and can be any place.

The inter-lens distance adjustment mechanism Y capable of adjusting the inter-lens distance between the pair of lenses 21R and 21L includes the pair of lens holders 22R and 22L described above; The opposing faces 22b of the pair of lens holders 22R, 22L form mutually engageable sector gears 26R, 26L.

By this, when the lens holders 22R, 22L are rotated in such a manner that the pair of lenses 21R, 21L approach each other, the distance between the lenses is narrowed, and the pair of lenses 21R, 21L are separated from each other in a manner of rotating the lens to maintain In the case of the devices 22R and 22L, since the distance between the lenses is widened, the distance between the lenses between the pair of lenses 21R and 21L can be adjusted in accordance with the eye width of the observer.

Further, when the lens holders 22R and 22L are rotated, the lens holders 26R and 26L are meshed with each other, and the lens holders 22R and 22L are rotated in conjunction with each other. Therefore, the work accompanying the adjustment of the distance between the lenses can be reduced. burden.

Further, the inter-lens distance adjusting mechanism Y includes a swirling over-rotation limiter 27 of the lens holders 22R and 22L. The over-rotation limiter 27 is provided with an over-separation limiter 27b that prevents the pair of lens holders 22R and 22L from being excessively close to each other, and an excessively spaced apart restrictor 27b that prevents the pair of lens holders 22R and 22L from being excessively separated.

The over-limiter 27a is a tab protruding from the opposing surface 22b at the rear of the lens holders 22R, 22L, and is integrally formed with the lens holders 22R, 22L. The approaching limiter 27a is disposed so that the restrictor 27a abuts against each other when the distance between the lenses reaches a predetermined lower limit value (for example, 58 mm). The specific arrangement position or length of the proximity limiter 27a is arbitrarily set in accordance with the lower limit value of the distance between the lenses.

The excessive alienation restrictor 27b is a pin that is disposed in a notched portion 22c that is cut into a rectangular portion of the opposing faces 22b of the lens holders 22R, 22L and that is erected on the support table. The excessive alienation restrictor 27b is disposed such that the inner peripheral surface 22d of the notch portion 22c abuts the sparse restrictor 27b when the lens interval reaches a predetermined upper limit value (for example, 72 mm). The arrangement position or size of the alienation limiter 27b is a response lens The upper limit of the distance is arbitrarily set.

Thereby, the over-rotation limiter 27 suppresses excessive rotation of the lens holders 22R and 22L, and can flexibly adjust the inter-lens distance between the pair of lenses 21R and 21L within a desired range.

As described above, the stereoscopic imager/stereoscopic viewfinder 1 of the present embodiment can adjust the inter-lens distance in accordance with the eye interval of the observer in addition to the effect that the stereoscopic imager/stereoscopic viewfinder 1 of the first embodiment can obtain.

Next, the fifth embodiment will be described. The pair of left and right lens units 50 shown in Figs. 14a, b, and c are different from the stereoscopic image viewer/stereo viewfinder 1 shown in Fig. 12, and the display D, the hood 10, the column 16, and the like excluding the lens unit. It is the part common to Figure 12.

The lens unit 50 shown in Fig. 14a is such that the bottom plate 240 is attached to the lower portion in a state where the display D can be rotated by 90°. The lens holders 52R and 52L, which will be described later, are attached to the lower left and right sides of the bottom plate 240, and the holes (unmarked) of the pins 54R and 54L of the left and right fulcrums which are rotated are provided. Further, the portions where the lenses 51R and 51L are overlapped are provided with holes 53R and 53L larger than the lens so that the lens holders 52R and 52L are not rotated.

In other words, the left and right lens holders 52R and 52L are rotatably attached to the bottom plate 240 around the respective pins 54R and 54L by the left and right pins 54R and 54L. Further, the left and right lens holders 52R and 52L are biased toward each other by the spring 57.

Further, in the intermediate portion between the left and right lens holders 52R and 52L in the left-right direction, a cam shaft 56 is inserted into a hole (no mark) opened in the bottom plate, and a cam 55R and a cam 55L are attached to the cam shaft 56, and the cam shaft is rotated by a finger. At the head of 56, 俾 finally adjusts the interval between the left and right lenses 51R, 51L.

Fig. 14b is a partial cross-sectional view centered on the cam shaft 56, showing a state in which the cam 55R pushes the end surface of the lens holder 52R, and the cam 55L pushes the state of the lens holder 52L. The cams 55R and 55L are actually extremely thin objects of about 1 mm. To prevent floating, it is preferable to mount the washer 58 of Fig. 14b. The washer 58 is press-fitted toward the shaft, even if it is rotated together.

14c is an example of a state in which the cam shaft 56 and the cam 55R and the cam 55L are assembled. A key groove is formed in the cam shaft 56, and a position of the cam 55R and the cam 55L in the rotational direction is held with respect to the cam shaft 56. The keyway can be two paths, but it is necessary to set the two grooves correctly, and even if it is a small axis, the groove must be mechanically processed. Because it requires a lot of labor, it is better to set a groove.

Further, since the cams 55R and 55L are punched by a press (thickness and thickness of 1 mm), the position of the portion where the key groove is fitted with respect to the hole is opposite to that of 55R and 55L, and there is no problem. Further, although it is considered that the cams 55R and 55L have only the same cam rotated by 180°, since the end faces of the lens holder 52R and the lens holder 52L are not parallel, the same contour cam cannot be used due to the change in the contact angle. It is necessary to make two kinds of cams.

Further, the interval adjustment between the left and right lenses may be such that the movement amounts of the left and right lenses are not completely the same. In this case, the same can be used for the left and right cams.

Further, the left and right cams have a step difference between the right and left in the thickness direction. Therefore, the lens holders 52R and 52L that abut against the cams 55R and 55L are also required to have a step, but the thickness of the lens holders 52R and 52L is about 1 mm, and since the thickness of the cam is also about 1 mm, the front and rear are left and right. The end faces of any of the lens holders 52R and 52L may be bent at the position of the upper cam.

Also, it is a user who is a normal camera, as shown in FIG. A hood 60 is also used. When the hood 60 is folded, the left and right side walls 63, 64 are folded in either order, and then the rear side wall 62 is folded, and the front side wall 61 is finally folded. It is somewhat inconvenient to use the hood 60, but it is inexpensive and economically advantageous.

The other embodiment of the hood shown in Fig. 15 is different from the hood shown in Figs. 5 and 6, and cannot be opened and closed by a simple operation. When the hood of Fig. 15 is to be opened, first, the front side wall 61 is opened, and then the rear side wall 62 is opened, and then opened in the order of opening either the left and right side walls 63 or 64. Moreover, when the hood shown in the figure is to be closed, the left and right side walls 63 or 64 are sequentially closed in the reverse order of opening, and then the rear side wall 62 is closed, and the front side wall 61 is closed. As a result, it takes time and labor to open and close than the hood shown in FIG. 5, but the design is easy and the manufacturing cost is small.

The illustration may be omitted. The loupe 20 shown in FIG. 15 may be incorporated with the magnifying glass 20 of FIG. 1 and the display (pattern) shown in FIG. 3, the second embodiment shown in FIG. 7, or the third embodiment of FIG. The stereo camera/stereo viewfinder and the stereo camera 2 are configured. Fig. 16 is a view showing a state in which the stereoscopic viewfinder 1 is attached to the stereo camera 2, and has a structure in which the display can be rotated 90° upward, and the figure is rotated by 90° in the direction of the arrow.

17 is an example of a configuration in which the stereoscopic viewfinder 1 is attached to the stereo camera 2, and the holes 72 and 73 of the display are used as mounting holes. The hole 73 provided in the display is only the hole 73 provided beside the display, but the hole 72 is provided at the center of the face joint 78 (which may also be a hole of the face joint). The light can be mounted by sandwiching the holes 72 and 73 with pins 74 and 75 provided on the camera side.

The screw 80 is previously adjusted in length so that the maximum length of the screw tip is rotated more than the surface joints 77 and 78 when tightening. If it is a single For pure installation, only the screw 80 can be used, but it is necessary to press the coil spring 79 beforehand to exert the click effect. Further, since the pin 75 jumps out from the pin moving hole 83 by the coil spring 79, the pin moving member 76 prevents jumping out, and at the same time, the pin moving member 76 actually removes the stereo framing from the stereo camera 2. At the time of the device 1, the pin 75 advances according to the coil spring 79, so that it is not necessary to take time to retract the pin 75.

Therefore, the pin moving part 76 is also necessary. As far as the action is concerned, the screw 80 is not required, but if the pin moving part 76 is inadvertently moved, the stereo viewfinder 1 is instantaneously dropped from the stereo camera 2. Therefore, screw 80 is required to prevent falling.

Further, the joint 77 is press-fitted to the pin 74 provided on the camera side (Fig. 17b has a "step difference" in cross-sectional shape, but the performance of the illustration may be such that there is no such step difference). Further, the position of the rotational direction is positioned by the joint positioning pin 81. At this time, the connector 78 on the display side is integrally formed and positioned in advance. Further, since the tip end of the pin 74 provided on the camera side is loosely fitted to the hole of the joint 78, it can be easily attached even in a slightly inclined state. Then, when the loosening screw 80 moves the pin moving member 76 to the right direction, the front end of the pin 75 is retracted from the left end surface of the pin moving hole 83, so that the display D can be mounted.

Further, the surface joints 77 and 78 which prevent the display D and the hood from falling due to gravity or the like are provided. The face joint mechanism always acts as a coil spring 79 via the pin 75. Furthermore, the camera body and the display D themselves become the limiter of the lower limit direction of the rotation, and the limit value in the upper direction is opened by 90° (not limited by 90°), and the limiter 82 acts at its extreme position. Since the surface joints 77 and 78 act, there may be a case where the rotation exceeds 90°, so that the rotation is restricted by the stopper in the up and down direction, and the so-called display can be prevented from being inadvertently swirled during storage. effect.

Further, the illustration is omitted, and it is conceivable that the detachable memory is provided on the display side when it is detached from the camera and used as a stereoscopic image, or a connectable structure should be provided in advance. Further, the built-in battery or external power supply can be used, and the display drive mechanism should be provided on the stereoscopic side (display side).

The electronic device to which the stereoscopic imager and the stereoscopic viewfinder of the present invention are applied may be an electronic display having a stereoscopic image, and may be, for example, a mobile phone, a digital camera, or an image generating device.

Further, the present invention can be variously changed without departing from the spirit of the invention, and the invention can of course be applied to the changer.
