Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a trinocular lens for stereoscopic photography, which has exposure and film winding functions and is capable of immediately performing lenticular stereoscopic photography on an unexposed film loaded in advance. Attached film unit.

[0002]

2. Description of the Related Art A film unit with a lens is a so-called film-integrated camera having a function of taking a picture, which is also called a "shooting-only camera". It is used only for film shooting, and the camera body is generally apt to be discarded after taking out the exposed film. Therefore, it is manufactured at a low cost with a simple structure.

In order to make a three-dimensional photograph, a lenticular system is generally called a lenticular lens, and thin lenticular lenses are arranged side by side on a photographic print so that a plurality of photographs with parallax can be seen little by little. Is made to be able to see. By looking at a plurality of photographs with a little parallax, it is possible to see a three-dimensional photograph with a natural three-dimensional effect that gradually changes depending on the viewing direction.

Most conventional cameras capable of performing lenticular stereoscopic photography are so-called lens shutter camera systems that use 35 mm film (J135). Therefore, the film can be arbitrarily selected by the user. Was completed.

The film winding, rewinding, exposure to the film, taking lens, focusing and the like are performed manually or automatically like the lens shutter camera, and the structure is also adopted in the lens shutter camera. The structure that had been used was almost followed.

Further, since there are three or more photographing frames for a lenticular stereoscopic photograph, even if the screen size is a half size, it is horizontally long and has a larger body than a normal lens shutter camera. Even from the above-mentioned structure, it was not lightweight.

[0007]

As described above, the conventional camera for performing lenticular type stereoscopic photography has a manual type mechanism such as film winding, rewinding, exposure to film, and photographing lens focusing. Regardless of whether it is an automatic system or not, the structure is complicated because it almost follows the mechanism of the lens shutter camera, and therefore the cost is also high, and the size and weight have to be increased. ..

Therefore, the marketability is not widened due to the fact that it is a special camera for lenticular type stereoscopic photography, mass production system cannot be set up, and therefore, it cannot be obtained unless it goes to an excessively large camera store. Therefore, even if a user tries to take a lenticular type stereoscopic picture, it is difficult to obtain a camera, and the price of the camera is expensive, so it is not possible to take a stereoscopic picture easily.

As a result of solving these problems and improving the present invention, as a result of the simplification of the mechanism of the camera and the utilization of space, the cost increase is suppressed, and the size is not so large. Another object of the present invention is to provide a film unit with a lens for three-lens type stereoscopic photography, which is capable of taking a lenticular type stereoscopic photograph image.

[0010]

SUMMARY OF THE INVENTION With the above object, the film is preliminarily wound on the spool in the scroll chamber so that the film can be photographed immediately, and the films are arranged in adjacent film feeding directions.
On the film screen of the frame, an image for making a three-dimensional photograph is taken by projecting an image by each lens facing the film screen on the film screen, and three films are filmed by the winding operation of the film winding knob. The film which has been wound up and photographed is sequentially rewound into the patrone of the patrone room, and the screen size of the film frame of the three frames is almost half size (16.5 to 18 mm x 23 to 24 mm). This is achieved by a film unit with a lens for eye type stereoscopic photography.

For the above-mentioned purpose, the lens interval of each lens facing the film frame of the three frames is 17.3 to 19
It is achieved by a film unit with a lens for three-dimensional stereoscopic photography, which is characterized by being in the range of mm.

Further, the above-mentioned object is that the film unit with a lens for three-lens type stereoscopic photography has a film sensitivity of IS.
This is achieved by a film unit with a lens for three-lens type stereoscopic photography, which is loaded with a film of O400 or more.

Prior to mounting the front cover 20 on the camera body 10, a decorative cover 22 is fixed to the front surface of the front cover 20 in advance.
The makeup cover 22 has a guide pin 22A and four nails 22 on the back.
B are projected, and each is a hole 20A on the front of the front cover 20.
And 4 are engaged and attached to the locking portions 20B.

The front cover 20 is provided with a hole 20C, a claw 20D, and three engaging portions 20E on the back surface, and the front cover 20 has a guide pin 10E, a nail 10F and a side engaging portion 10G on the entire surface of the camera body 10. It is fitted and attached.

By mounting the front cover 20 on the camera body 10, the lens retainer 13 and the strobe unit 40 are fixed to the camera body 10.

The camera body 10 with the front cover 20 attached
In the cartridge chamber and the scroll chamber (both not shown) formed on the back surface of the cartridge, the cartridge P1 and the spool S2 with the leading end of the unexposed film F locked are respectively loaded.

The other end of the film F is locked to the spool S1 in the cartridge P1. Even if the film in the cartridge is wound up by the spool S2 after the film is loaded, the other end is locked to the spool S1. Therefore, it can be rolled up in the Patrone P1 every time the shooting is completed.

A back cover 30 is attached to the back surface of the camera body 10 in which the film F is loaded, and the regulation of the position of the film F on the light-shielding focus surface is maintained.

The back cover 30 is provided with claws 30A and 30B on the front surface thereof and locking holes 30C and 30D on the side surfaces thereof.
Claws 30A and 30B are engaged with the camera body 10 when mounted on the camera.
Holes 30C and 30D and one hole (not shown) are fixed to 10H and 10J by engaging with nails 10K and 10L of the camera body 10 and one nail (not shown).

After the back cover 30 is mounted, a predetermined film winding operation is performed to set a photographable screen, and the carton shown in FIG. 1 is mounted and completed.

Next, details of the film winding mechanism 50, the shutter charge mechanism 60, and the film counter mechanism 70 will be described.

FIG. 3 shows each of the above-mentioned mechanisms at an angle when viewed from the rear side of the camera, and FIG. 4 shows at an angle when viewed from the side of inserting the film-wrapped cartridge and spool into the camera body. It is a thing.

The camera body 10 has an approximately half-size exposure portion (specifically, a width of 16.5 to 18 mm and a length of 23 to 24 mm).
In the same plane on both sides of the three screen frames 16 arranged side by side in the left-right direction, a cartridge chamber 15A and a scroll chamber 15B are provided as two storage chambers for film winding and film loading. The J135 film F wound in the cartridge P1 which is the storage container shown in FIG. 4 is loaded.

The present camera is provided with three half-size screen frames arranged side by side in the left-right lateral direction as described above, and is adapted to capture a lenticular-type stereoscopic image.

In order to obtain a natural three-dimensional effect, it is preferable that the lenticular type stereoscopic photographic image is photographed on as many side-by-side horizontal and lateral (film feeding direction) screens as possible, but the number of screens is large. Obviously, the lateral size of the camera becomes large. That is, the camera becomes large. Therefore, in the case of a camera for taking a stereoscopic photographic image of a normal lenticular system, a three-screen system or a four-screen system is adopted.

When a 35 mm film (J135) is used, the size of the screen frame for preventing problems in the processing room is the so-called full size (24 × 36 mm) screen and half size screen. Is. And, of course, if you choose the full-size screen size, the lateral size of the camera will naturally increase. Therefore, in order to make the camera compact, the present inventors chose a half size screen size.

Therefore, in the present camera, it has been proposed to provide a lens unit film unit having three screen frames of a half size as described above, that is, a lens unit for three-lens type stereoscopic photography. The back cover opening and closing structure provided in the camera is greatly simplified to reduce the size and cost of the camera.

That is, the hinge portion and the tightening claw portion of the back lid opening / closing structure provided in a normal camera are omitted, and the equivalent to the hinge portion is used only once when taking out the patrone after photographing. A groove 32 is provided in the back cover 30 shown in FIG. 2 for bending and taking out, and as the one corresponding to the tightening claw portion, the claws 10K and 10L of the camera body 10 and the back cover are described above.
30 nails 30A, 30B are holes 30C, 30D of the back cover 30, the camera body
The back cover 30 is engaged with the locking portions 10H and 10J of the 10 to make the camera body 10
It is designed to be fixed to.

The film F used in this camera of this embodiment is a roll film J135 in the case of a commonly used patrone (JISK7528), or J135 in the case of a patrone having the above-mentioned outer diameter of φ20.6 mm. A film or a roll film with a slightly thin total thickness of 130 to 140 μm can be stored in a dark room etc. in advance in a dark room.
The end of the spool S1 is fixed to the spool S1 and the film is wound up for a predetermined number of frames so that the film can be photographed. The film in this state will be loaded into the camera. The loading method will be described below.

As shown in FIG. 3, the cartridge is loaded in the cartridge chamber 15A so that the spool S1 (shown in FIG. 4) of the cartridge P1 is engaged with the fork 52 of the hoisting fork 52. On the other hand, the spool S2 is also inserted in the scroll chamber 15B. Then, in this embodiment, the film F is pulled out until the tip of the film notch FN of the film F is aligned with the index 17A on the lower portion of the lower rail surface, and the tip of the film F is inserted into the slit SL of the spool S2 so that the film F The perforation P is locked to the claw H. The film notch FN is designed to indicate the emulsion lot number of the film by means of several holes provided in the tongue portion at the tip of the film.

Next, the back cover 30 is covered and the cover is made light-tight.
Then, this camera in this state is attached to the film winding device, and the entire film F (with the other end not separated from the spool S1 of the cartridge P1) is moved to the scroll chamber 15B.
The film is loaded by winding the film on the spool S2. That is, by loading the film F in this manner, the film F is sequentially wound into the patrone P1 for each shooting, and after a predetermined number of shootings are completed, in this embodiment, two films, that is, 6 frames are taken. When the blank feed is performed, the leading end of the film F is not caught in the cartridge, and the filmed portion of the photographed film is completely caught in the cartridge P1 with a necessary length left. Therefore, this cartridge can be taken out from this camera in a bright room.

Next, the mechanism of the main body will be described with reference to FIG.

The camera body 10 includes a film winding mechanism 50 including a photographing lens, a shutter charging mechanism 60,
The main mechanism of the film counter mechanism 70 is incorporated therein.

First, the film winding mechanism and the shutter charging mechanism will be described.

Reference numeral 51 is a film winding knob, and the film F loaded as described above is wound by rotating the film winding knob 51 counterclockwise. A cam 55 coaxial with the 12-tooth sprocket gear 54 meshing with the perforation P of the film F and having a fan-shaped cam portion 55B at the lower portion.
Is designed to rotate exactly once counterclockwise by winding the film.

That is, the film is wound up by taking the length of 12 perforations, which is the number of teeth of the sprocket gear, as the length of one shot, and the frame size is almost half the size of the frame, so the winding length is 3 It is the length of a piece.

As described above, the structure in which the sprocket gear of the film feeding means makes one revolution for each photographing is as follows.
The film winding mechanism, the shutter charging mechanism, the film counter mechanism, etc. can be made into a simple structure, which is very effective for cost reduction.

By the counterclockwise rotation of the cam 55, the fan-shaped cam portion 55B naturally rotates counterclockwise as described above, and in the process, the fan-shaped cam portion 55B causes the charge lever 61 to move to the charge lever shaft 63. Is rotated clockwise against the spring force of the charge lever spring 64 that urges the charge lever 61 in the counterclockwise direction, and the triangular ketobashi 61C provided on the charge lever 61 causes the rising portion 65 of the shutter lever 65 to rise.
When B is pressed, the rising portion 65B is overcome and the shutter charge mechanism is charged as shown in the figure.

Pin 65C of the shutter lever 65 and the camera body
The shutter spring 67 is stretched between the pins 18C provided on the pin 10. The pin 18B provided on the camera body 10 that guides the elongated hole of the shutter lever 65 slidably and rotatably by the pulling force of the shutter spring 67. The left end of the elongated hole is brought into contact with the arm plate 65D provided on the shutter lever 65 and the pin 18E provided on the camera body 10. Also the camera body
A shutter drive pin 65A for operating a shutter drive lever 66A pivotally supported by a pin 18D provided on the pin 10 is inserted into the forked portion of the shutter drive lever 66A. Then, at a pin 66B at the lower end on the opposite side of the shutter drive lever 66A, the shutter drive lever 66A engages with a shutter blade 66 guided so as to be slidable in the left-right direction.

As will be described later, the cam stopper after the shooting is completed.
The projecting portion 62D of 62 is removed from the groove portion 55A of the cam 55,
The arm portion 57A of the hoisting stopper 57 changes from the state shown in the drawing to change the arm portion 61A of the charge lever 61 and the arm portion of the cam stopper 62.
The arm 62A is in contact with the end surface of the arm portion 61A by the spring force of the hoisting stopper spring 58 which is displaced from each edge of the arm 62A and urges clockwise. When the cam 55 rotates exactly once as described above by the film winding and the groove 55A of the cam 55 returns to the initial position, the spring force that biases the cam stopper 62 in the clockwise direction by the horizontal end portion of the charge lever spring 64. As a result, the protrusion 62D of the cam stopper 62 jumps into the groove 55A. By this jumping operation, the lock of the arm portion 57A of the hoisting stopper 57, which was locked at the end surface of the arm portion 62A of the cam stopper 62 at this time, is released.

The outer peripheral cylindrical surface of the film winding knob 51 is a ratchet gear, and the V-shaped protrusion at the tip of the winding stopper 57 is released by the release of the locking, and the ratchet force is applied by the winding stopper spring 58. It jumps into the tooth groove of the gear 51A and prevents the film winding knob 51 from rotating in the counterclockwise direction. That is, when the film winding is completed, the film winding knob 51 is prevented from further rotating.

Further, in the camera body 10, the tip of the reverse rotation preventing claw 53 utilizing the elasticity of the resin material is pressed against the ratchet gear 51A so as to prevent the film winding knob 51 from rotating in the opposite direction. It has become.

By pressing the release button 25 of the front cover 20, the release button pin 25A is planted on the back surface of the release button 25.
Operates in the direction of arrow A. That is, the front cover 20
When attached to the camera body 10, the winding knob
51 By the operation of the tip of the release button pin 25A in the direction of arrow A described above, the hoisting stopper 57 rotates counterclockwise against the spring force of the hoisting stopper spring 58. Then, from the end surface of the arm portion 57A of the hoisting stopper 57, the arm portion of the charge lever 61
The edge of 61A is disengaged, and the charge lever 61, and thus the cam stopper 62, is rotated counterclockwise by the spring force of the charge lever spring 64.

The counterclockwise rotation of the charge lever 61 by the spring force of the charge lever spring 64, which is stronger than the shutter spring 67, causes the charge lever 61 to move in the above-mentioned direction.
61C hits the rising portion 65B of the shutter lever 65, and then comes off the rising portion 65B. Therefore, the shutter lever 65
Rotates clockwise around the pin 18B in the long groove of the shutter lever against the tensile force of the shutter spring 67, and then returns to its original state by the tensile force of the shutter spring 67. Therefore, the shutter drive pin 65A rotates the shutter drive lever 66A about the pin 18D, and the pin 66B at the lower end of the shutter drive lever 66A.
The shutter blades 66 engaged with the shutter blades 66 are slid to the left and right, and the films of the three screen frames 16 are exposed at the same time by the square holes provided in the shutter blades 66 and then closed.

On the other hand, the cam stopper 62 also rotates counterclockwise together with the charge lever 61 as described above,
The protruding portion 62D of 62 is removed from the groove portion 55A of the cam 55. Therefore, even if you stop pressing the release button, the winding stopper
The arm portion 57A of 57 is biased in the clockwise direction by the spring force of the hoisting stopper spring 58, but the arm portion 61A of the charge lever 61.
Is stopped by the end face of the
The shaped protrusion does not lock the ratchet gear 51A of the winding knob 51. Therefore, the next film winding can be performed.

Next, the film counter mechanism will be described.

As described above, 72 meshes with the V groove 56A provided at the upper end of the cam shaft 56 which is planted in the cam 55 which rotates integrally with the sprocket gear 54, so that one film of film, that is, three frames is formed. It is an exponential gear that rotates clockwise by one tooth each time the cam shaft 56 is wound up and rotated once.

An index plate 71 is printed on the upper surface of the index wheel gear 72 as an integrally molded product, and the remaining number of film-capable images is displayed through the film counter window 26 on the upper surface of the front cover 20.

A projecting portion 72A is provided on the lower surface of the index plate gear 72, and the projecting portion 72A is projected by the projecting portion 61 of the charge lever 61 by the next film winding after the predetermined number of photographing is completed.
It is designed to be inserted between the E and another protruding portion 62E of the cam stopper 62 so as to enter. Then, the projecting portion 72A is replaced by the two projecting portions 61.
By entering between E and 62E, the film is wound up for one shot, and even if the cam 55 makes one rotation and charging of the shutter is completed, both of the projecting portions 61E and 62E become the projecting portion 72A of the exponential gear 72. Since the movement is blocked, the charge lever 61 cannot operate and the protruding portion 62D of the cam stopper 62 cannot jump into the groove portion 55A of the cam 55. The arm portion 57A of the hoisting stopper 57 contacts the end surface of the arm portion 62A of the cam stopper 62 by the spring force of the hoisting stopper spring 58, and the V-shaped projection at the tip of the hoisting stopper 57 locks the ratchet gear 51A. Also, it is impossible to expose the film by operating the charge lever 61 to open and close the shutter blades.

As described above, in the present embodiment, when the film is fed in two shots, the index plate gear 72 rotates by two teeth, and this rotation causes the projection 72A of the index plate gear 72 to move. Although the protrusion 61E is pressed to prevent the charge lever 61 from moving, the cam stopper 62 is detached from another protrusion 62E. Therefore the protrusion
62D jumps into the groove 55A of the cam 55, and the winding stopper 57 is disengaged, so that the winding stopper 51 locks the winding knob 51, so that the film cannot be wound. Further, as described above, the movement of the charge lever 61 is blocked so that the film cannot be exposed. In this way, the tongue at the leading edge of the film is prevented from being caught in the cartridge and the tongue of the required length is secured. Therefore, in order to make the camera compact, even if a cartridge having a small outer diameter is used, there is no problem in pulling out the film from the cartridge at the time of development.

Next, the sensitivity of the film loaded in this camera will be described.

This camera is loaded with a film having a sensitivity of ISO400. By using the ISO400 film, it is possible to narrow down the shooting by 2 apertures compared to the ISO100 film that is generally used, and thus it is possible to increase the depth of field. As a three-dimensional photograph, the subject is focused from a short distance to a long distance so that a natural three-dimensional effect can be obtained.

Further, by using the ISO400 film, the exposure latitude is wider than that of the ISO100 film which is generally used. Therefore, fixed exposure (fixed shutter speed, fixed lens aperture) is used for cost reduction. ) Does not cause any problems with exposure in fine weather during the day, and strobe photography does not cause problems in dark places.

[0072]

According to the present invention, the cost increase is suppressed by simplifying the mechanism of the camera and utilizing the space, and moreover, it is easy, reliable, and inexpensive to take a stereoscopic photographic image of a lenticular system without being so large. A film unit with a lens for three-lens type three-dimensional photography that can be performed is provided.
