Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a film unit with a lens, which has an exposure function and a film winding function, and can immediately take a photograph of a pre-loaded unexposed film.

[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 discarded after taking out the exposed film. Therefore, it is manufactured at a low cost with a simple structure.

In many cases, the camera is purchased and used on the go while traveling, but it cannot be said that it is convenient to carry, and it has a photographing lens of f = 35 mm and an outer shape of 110 mm × 6.
It was about 0mm x 35mm, and I couldn't fit it in the chest pocket of my shirt, which was inconvenient.

[0004]

However, although it is said to be a "camera that is completely shot", the camera function has been enhanced as in the case of a lens-equipped film unit with a built-in stroboscopic light emitting device, due to the recent diversification of shooting purposes. There is a tendency for that reason, and the increase in cost and the increase in camera size are inevitable.

Further, from the idea of reusing resources, it has been demanded that the “shooting-only camera” be a reusable camera, that is, a reuse camera.

In order to be able to reuse the camera as it is, it is naturally necessary to recheck the camera for quality assurance, and if only the minimum necessary members are replaced. There is an increasing demand for cameras that can be reused.

That is, there is a growing demand for a reusable camera having a means for preventing the film from being refilled and used without checking the camera. Therefore, if the user can easily take out the cartridge and assemble it with a new cartridge, a camera that does not meet the quality standards such as the optical system and strobe will be a problem.

Needless to say, it is necessary that the cartridge be easily taken out at a predetermined place (development shop or manufacturer), and the reliability of the cartridge should not be deteriorated by the replacement of the cartridge. It should be easy to process.

As a result of improving these points, the present invention suppresses the cost increase by simplifying the mechanism of the camera and utilizing the space, and improves the durability of the locking portion for locking the back lid of the film unit with lens. The purpose of the present invention is to provide a film unit with a lens that improves and promotes reuse.

SUMMARY OF THE INVENTION The above-mentioned object is to allow a film to be photographed immediately when a pre-formed film is wound on a spool in a scroll chamber, and to wind a film by one frame by a film winding knob to shoot a film. After finishing the film, rewind it in the patrone of the patrone room one by one,
The patrone is a lens-equipped film unit that is light-tightly covered by a detachable outer shell portion, wherein at least three engaging portions for attaching the outer shell portion to the body of the lens-equipped film unit are in three directions. It is achieved by a film unit with a lens.

Another object of the present invention is to allow a film to be photographed immediately when the film is wound on the spool of the scroll chamber, and the film is wound up by one frame by the film winding knob, and the film which has been filmed is finished. In the lens-equipped film unit that is sequentially rewound into the patrone in the patrone chamber, take out the patrone with the film that has been photographed taken in, and remove the patrone by locking the back cover attached to the body of the lens-equipped film unit. , The patrone chamber side is opened by taking out only some of the locking parts, and the back cover is removed when replacing the back cover so that it cannot be removed without releasing the remaining lock. It is achieved by a film unit with a lens characterized in that it is configured, further the above-mentioned object, Locking portion for locking the back cover to the body 4
It is characterized in that there are only one hook engaging portion to be removed when removing the cartridge from the groove provided on the back lid when removing the cartridge, and the remaining three hook engaging portions to be removed when replacing the back lid. This is achieved by the lens-equipped film unit.

The locking portion C1 has a locking direction indicated by an arrow in which the X direction is directed inward like the hook locking portions A1 and B1, and locks the back cover 30 to the camera body 10.
In this way, the back cover 30 is locked to the camera body 10 at least at three positions in three locking directions facing the inside of the camera.

Since the hook engaging portions A1, B1 and C1 have such a positional relationship, the back cover 30 is mounted on the camera body 10 in a well-balanced manner, and the hook engaging portion C1 of the hook engaging portion C1 is taken out when the cartridge is taken out as described later. When the back cover 30 is bent in the groove 32 by releasing only the hook lock, the back cover 30 is hook-locked to the main body 10 by the hook lock portions A1 and B1 at two places on the left side of the groove 32. The case back 30 can be easily bent at the position of the groove 32.

FIG. 6 is a view showing the taking out of the film from the camera. In FIG. 6, the hole 30C of the back cover 30 is engaged with the claw 10K of the camera body 10. A minus driver-like metal fitting with a sharp tip is inserted in this hole or the engaging part between the locking part and the claw. The lever is disengaged, and the other holes of the back cover 30 and the other claws of the camera body 10 are left in the engaged portions.
Bend the back cover 30 from the groove 32 and move the back cover 30 from the state I to II.
Spread to the state of. Then, from the camera body 10, insert the cartridge P1 in which the film that has already been photographed has been rolled up into the arrow B
I will take it out in the direction.

As described above, in this camera, one of the three hook engaging portions between the back lid and the camera body is released, the back lid is bent at the groove, and the cartridge side is opened by opening the cartridge side. Is easy to retrieve. This one place can be easily opened by the lab. However, it is desirable that the remaining two places are not possible in principle.

Although not shown, in the remaining two places, unless the specific member is pushed in and removed, the engaging portion on the main body side is destroyed,
It can be configured so that it cannot be used, and it can be opened only with a special jig (owned only by the manufacturer).

FIG. 7 is a diagram showing another embodiment.

As in the case of FIG. 5, FIG. 7 is a perspective view of the camera seen from the rear side, and in order to make it easy to see the hook engagement between the back cover and the camera body, the main parts are shown as in the case of FIG. This is an emphasis.

In FIG. 7, A2, B2, C2 and D indicate hook engaging portions which are attached by attaching the back cover 30 to the camera body 10 at four positions. Of these four hook engaging portions, A2 and B2 are the upper and lower parts near the groove 32 for bending the back cover when taking out the cartridge provided on the back cover as in the case of FIG. It is a hook locking portion that locks. Note that taking out the cartridge from this camera is exactly the same as the method described in FIG. As in the case of FIG. 5, the hook engaging portions A2 and B2 are provided as a pair at opposing positions. Among the engaging directions indicated by the arrows, the X and Z directions are the same and the Y direction is the same. The back cover 30 is locked to the camera body 10 in the opposite direction.

The hook engaging portions C2, D are hook engaging portions for engaging the back cover 30 with the camera body 10 at substantially the center of the left and right positions. The locking parts C2, D are hook locking parts A2,
Like B2, they are provided in a pair at opposite positions, and in the locking direction shown by the arrow, the Y and Z directions are the same direction and the X directions are inward directions opposite to each other, and The lid 30 is locked to the camera body 10.

As described above, the hook engaging portions A2, B2 and C2, D are paired, and the hook engaging portions A2, B2 in the Y direction and the hook engaging portion are included in the pair of engaging directions. The X-directions of C2 and D are opposite to each other and the lines passing through the hook engaging portions A2 and B2 and C2 and D intersect at a right angle. Then, the hook engaging portion A
2, the Y direction of B2 and the X direction of the hook engaging portions C2, D are inward directions opposite to each other, but the hook engaging portions at the positions intersecting at right angles are in the X direction. Since the hooks are further hooked in both the Y and Y directions, there is no problem with hook hooking. Hook locking part A2, B2, C2, D
Since the back cover 30 is in such a positional relationship, the back cover 30 is mounted on the camera body 10 in a well-balanced manner, and the back cover 30 is removed by removing only the hook locking of the hook locking portion C2 when taking out the patrone described above. Back cover 30 when folded in the groove 32
Are three hook engaging parts A2, B2, D on the left side of the groove 32
Since it is hooked to the main body 10 by the
Can be easily bent at the position.

As described above, in this camera, one of the four hook engaging portions between the back lid and the camera body is disengaged, the back lid is bent at the groove portion, and the cartridge side is opened by opening the cartridge side. Is easy to retrieve.

Since the back cover is locked to the camera body in three or more directions in this way, a special jig is required to attach the back cover, and the user cannot easily attach or detach the back cover. I can't.

The camera from which the cartridge has been taken out in this way is sent to the manufacturer side with the back cover attached, and the back cover is removed by removing the remaining three hooks from the camera. Function and performance are checked. Then, the accepted camera is loaded with a new unexposed film cartridge by the loading method described later, a new back cover is attached, and immediately ready to be photographed and provided to the user.

As described above, the back cover is attached to the camera body until the manufacturer removes the cartridge from the developing station.

Therefore, the case where the cartridge is taken out and the half-opened state is easily removed from the camera body at the developing station or before returning from the developing station to the manufacturer side. The case back is dissipated, which is a problem in terms of resource reuse. However, in the case of the present embodiment, even after the cartridge is taken out, the back cover is locked to the main body at three places in particular, so that it does not easily come off.

In this way, the locking portion between the back cover and the camera body is first removed at one of the four locations at the developing station, and the cartridge is taken out. Then, it is sent to the manufacturer side, where the remaining three locking parts are released and the back cover is removed from the camera body. That is, the back cover is removed for replacement of the back cover. There may be four or more hook engaging portions, and one or more engaging portions may be removed when the cartridge is taken out. Further, the camera body is reused, but the back cover is used only once, so that the part on the body side where the back cover is hooked to the camera body is easily damaged. Therefore, the material of the resin material of the back cover is preferably softer than the material of the camera body.

Further, taking out the cartridge is not limited to the method in which the back cover is bent and taken out, but the outer shell component may be bent and taken out, for example, the side wall or the bottom wall may be bent and taken out.

The details of the film winding mechanism 50, the sector charge mechanism 60, and the film counter mechanism 70 will be described below.

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

In the camera body 10, a cartridge chamber 15 is provided as two accommodating chambers for film winding and film loading in the same plane on both sides with the screen frame 16 which is the exposure unit interposed therebetween.
A and a scroll chamber 15B are provided, and J135 caught in the cartridge P1 which is the storage container shown in FIG.
The film F is loaded.

The film F used in this camera of this embodiment is a roll film J135 or a slightly thin roll film having a thickness of 130 to 140 μm, which is the same as a general camera. The end portion is fixed to 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.

The cartridge P1 is loaded in the cartridge chamber 15A so that the spool S1 of the cartridge P1 engages 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 way, the film F is successively wound into the patrone P1 for each shooting, and after the shooting of a predetermined number of frames is completed, in the present embodiment, two frames are skipped. Then, the front end of the film F is not wound in the cartridge, and the film having been photographed is wound 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.

The camera body 10 includes a film winding mechanism 50 including a photographing lens 12, a sector charge mechanism 60,
The main mechanism of the film counter mechanism 70 is incorporated therein.

First, the film winding mechanism and the sector charge mechanism will be described.

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

That is, the film is wound up with the length of eight perforations, which is the number of teeth of the sprocket gear, as one frame, and the frame size is a so-called full size frame size of 24 × 36 mm.

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 moves the charge lever 61 and 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 a counterclockwise direction, and the triangular ketobashi 61C provided on the charge lever 61 causes the rising portion 65B of the sector lever 65 to rise.
Is pressed, and the rising portion 65B is eventually overcome to charge the sector charge mechanism as shown in the figure.

Pin 65C of the sector lever 65 and the camera body 10
A sector spring 67 is stretched between the pins 18C provided at the sector lever 67, and the tensile force of the sector spring 67 causes the sector lever 65 to move.
The left end of the elongated hole is brought into contact with a pin 18B provided on the camera body 10 that guides the elongated hole of the camera in a slidable and rotatable manner, and the sector lever
Pin 18 provided on camera body 10 with arm plate 65D provided on 65
It comes in contact with E. Further, a sector drive pin 65A for actuating the sector 66 pivotally supported by the sector pin 18D provided on the camera body 10 is inserted in the forked portion of the sector 66.

As will be described later, the cam stopper after 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 projection at the tip of the winding stopper 57 is released by the release of the engagement, and the spring force of the winding stopper spring 58 causes the ratchet to rotate. 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 winding rotation.

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 winding 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 25 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 face of the arm portion 57A of the hoisting stopper 57, the arm portion 61 of the charge lever 61
The edge of A 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 charge lever 61 is rotated counterclockwise by the spring force of the charge lever spring 64, which is stronger than the sector spring 67.
C hits the rising portion 65B of the sector lever 65 and then comes off the rising portion 65B. Therefore, the sector lever 65 rotates clockwise around the pin 18B in the long groove of the sector lever against the tensile force of the sector spring 67, and the sector spring 67
It returns to its original state due to the pulling force of. Therefore, sector drive pin 65A
Will rotate sector 66 about sector pin 18D to expose the film and then close it.

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 that is planted in the cam 55 that rotates integrally with the sprocket gear 54, and one frame of film is wound up to form a cam shaft. It is an exponential gear that rotates clockwise one tooth each time 56 rotates 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 exponential gear 72, and the projecting portion 72A is projected by the next film winding after the predetermined number of frames have been photographed.
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 by one frame, and even if the cam 55 makes one rotation and the charging of the sector is completed, both the projecting portions 61E and 62E become the projecting portion 72A of the exponential gear 72. As the movement is blocked, the charge lever 61 cannot operate and the protruding portion 62D of the cam stopper 62 is also in the groove portion of the cam 55.
You will not be able to jump into 55A. The arm portion 57A of the hoisting stopper 57 contacts the end face 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 not possible to operate the charge lever 61 to open and close the sector to expose the film.

As described above, in the present embodiment, when two frames of film are fed in an idle manner, the index plate gear 72 rotates by two teeth, and this rotation causes the protrusion 72 of the index plate gear 72 to rotate.
A is a charge lever that holds down the protrusion 61E at all.
The movement of 61 is blocked, but another protrusion 62 of the cam stopper 62 is
It is designed to come off from E. Therefore, the protrusion 62D
Jumps into the groove 55A of the cam 55, the winding stopper 57 is disengaged, and the winding stopper 57 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.

In this lens-equipped film unit, the color of the cartridge is changed to blue, white, yellow, brown, etc., or the numbers 1, 2, 3 etc. are marked on the cartridge for reuse. The camera body that has been checked for quality assurance is loaded with a white cartridge or a cartridge marked "2" for the second use.
