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 an unexposed film loaded in advance.

[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 reusable cameras.

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.

As a result of solving and improving these points, the present invention enables reuse of resources as a reusable camera that can be easily reused by checking and exchanging some members. The purpose is to provide a film unit with a lens.

[0009]

SUMMARY OF THE INVENTION The above object is to allow a film to be taken immediately because the film is wound in a spool in a scroll chamber in advance, and the film is wound up by one frame by a film winding knob to finish the filming. The film was rewound into the patrone in the patrone chamber in sequence, and the patrone with the film taken after the filming was folded in a part of the outer shell part to open the patrone chamber and take it out with a lens unit, The present invention is achieved by a lens-equipped film unit, characterized in that the outer shell portion cannot be attached unless a special jig is used when it is attached to the body of the lens-equipped film unit.

Further, the above object is achieved by a film unit with a lens, which is characterized in that the bent portion is broken by bending when the outer shell portion is opened, and light cannot be shielded.

Further, the above-mentioned object is such that the engaging portion engaging the outer shell portion with the unit main body is constructed so that the engaging portion on the outer shell portion side is damaged by the act of removing the outer shell portion. This is achieved by a film unit with a lens characterized by:

[0012]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 shows an external view of a lens-equipped film unit of the present invention (hereinafter also referred to as the present camera), which is provided with a 35 mm film (J135) pre-loaded in the present camera, and after completion of photographing. The film is sent to the processing station with the film kept in the camera without rewinding, the film is taken out from the camera, and the film is developed and printed.

The unexposed film used in this camera is loaded by the loading method described below. In the loaded state, the film is wound from the cartridge to the spool.
It is designed to be rolled up in the Patrone each time it is taken. Therefore, in the photo lab, the photographed film can be taken out from the camera in the bright room.

It is possible to easily take out the photographed film by bending a part of the back cover as the outer shell portion. Therefore, the camera part is checked and a new unexposed film is loaded to the back cover. It will be possible to reuse if the manufacturer replaces it.

As the cartridge loaded in the camera, a cartridge having an outer diameter of φ20.6 mm, which is different from a cartridge (JISK7528) which is generally used, is used.

As a result, the thickness of the camera can be suppressed to about 24 mm except for the lens barrel portion having the taking lens, and an ultra-thin compact camera is realized.

The present camera is provided with a cardboard carton (paper cover) on the outer surface of which a product name, a simple method of use, etc. are displayed.

FIG. 2 is a development view showing the structure of the present camera.

These are the sector charge and film counter mechanisms.

When the camera body 10 is used alone, each member constituting the film winding mechanism 50, the sector charge mechanism 60, and the film counter mechanism 70 is mounted, and the shutter case 11 for housing the sector is mounted.

The shutter case 11 is fixed by engaging claws 11A provided on both sides with a locking portion 10A on the front surface of the camera body 10, and links the sector to the sector charge mechanism 60.

Further, on the front surface of the shutter case 11, a photographing lens 12 having a single lens having a focal length f = 30 mm and an aperture of F9.5 is dropped, and a slit 13A for engaging with a guide pin 11B is provided. Covered by lens presser 13.

The camera body 10 and the shutter case 11 described above
Are molded from a black matte plastic material having some elasticity, including the front cover 20 and the back cover 30 described above.

On the other hand, the strobe unit 40 is mounted and supported on the basis of holes 40A and 40B on the substrate which engage with the guide pins 10B and 10C on the front surface of the camera body 10, respectively.

In the strobe unit 40, the upper and lower battery contact pieces 41 integrated with each other are inserted through the slit holes 10D in the upper and lower portions of the camera body 10 and projected into the battery chamber on the rear surface of the camera body 10 to form an AA battery as a strobe charging power source. Hold a certain battery power source E.

Further, the integrated main capacitor C is stored in a capacitor chamber formed under the shutter case 11.

The lens retainer 13 and the strobe unit 40 described above
The fixing and integration of the above with the camera body 10 is completed by mounting the front cover 20 on the camera body 10.

Prior to mounting the front cover 20 on the camera body 10, a finder objective lens 21 is dropped in front of the front cover 20 and is fixed by engaging a decorative cover 22. The decorative cover 22 has a guide pin 22A and four claws 22B projecting from the rear surface thereof, which are respectively formed in the holes 20A and 4 on the front of the front cover 20.
It is attached by engaging with the locking portion 20B at the location.

The front cover 20 is further mounted on the front surface of the camera body 10 after the eyepiece lens 23 of the finder is engaged and mounted on the rear surface.

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 once 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.

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 to complete the process.

Now, the mounting of the back cover 30 on the camera body 10 will be described.

5A and 5B are explanatory views for attaching the back cover 30 to the camera body 10. FIG. 5C is a rear view of the camera and is a front view as seen from the back cover side, and FIG. A side view of a dedicated jig 100 for attaching the back cover 30 to the camera body 10 is also shown in a sectional view taken along the arrow. (B) is a top view including a cross-sectional view taken along the line YY of (c) and seen from the top, and at the same time, shows a top view of the dedicated jig 100.
(D) is a dedicated jig in the sectional view taken along the line YY of (c).
FIG. 3 is an enlarged view when the back cover 30 is attached to 100 and attached to the camera body 10.

In FIG. 5, the dedicated jig 100 for attaching the back cover 30 to the camera body 10 is a wedge pin hole 301C, 301 of the back cover.
Wedge pins 102C, 102D and 102E are attached to the same positions of the base 101 of the dedicated jig 100 corresponding to D and 301E. The positions of the wedge pin holes 301C, 301D, and 301E are set at the positions of the back cover 30 by engaging the claws of the camera body 10 with the holes of the back cover 30.
30 is a position where the camera body 10 is attached.

The wedge pins 102C, 102D and 102E are pins in which the tip of a round bar is obliquely cut as shown in the figure. Each wedge pin is pivotally supported by the base 101 through a seat having a slightly larger diameter.
Base 10 that can be rotated by turning the knob
It is attached to 1.

Next, the mounting of the back cover 30 to the camera body 10 with this dedicated jig will be described.

As shown in FIG. 5 (d), and also at the other two places, the wedge pin holes 301C and 3 of the back cover 30 are similarly formed.
01D, 301E, special jig 100 wedge pin 102C, 102D,
Insert it to the seat of 102E until it stops. Next, the V-grooves 30 provided at the joints between the side wall of the main body 10 and the side wall of the case back 30 of each wedge pin hole.
2C, 302D, 302E each wedge pin 102C, 102D, 102E
Turn the knob so that the direction of the sharp tip of is aligned as shown. Then, in this state, the back cover 30 is put on the camera body 10 and further, until the end face of the side wall of the back cover 30 comes into contact with the end face of the side wall of the front cover 20. This state is (d).
That is, the sharp tip of the wedge pin 102C enters the V groove 302C and lifts the side wall of the camera body, and the nail 10K and the hole 30C into which the nail 10K pops are in the state shown in the drawing. This state is of course the same for other claws and holes. Therefore, when the wedge pins are pulled out from the three wedge pin holes, that is, when the dedicated jig 100 is removed from the back cover 30, each of the claws jumps into the respective holes and the back cover 30 is locked to the camera body 10. This state is shown in (a) and (b).

Reference numerals 303C, 303D and 303E are light leakage preventing members made of a material such as moltoprene for preventing light leakage from the wedge pin holes 301C, 301D and 301E.

As described above, by using the dedicated jig 100, the end surface of the side wall of the back cover 30 is provided on the camera body 10.
It is possible to cover the camera body 10 with the back cover 30 to a predetermined position without being blocked by K, 10L and 10M. Therefore,
When the back cover 30 is attached to the camera body 10, it cannot be attached without this special jig.

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 of the back cover 30 to move the back cover 30 from the state I to II.
Spread to the state of. Then, the patrone P1 in which the photographed film showing the tongue has been wound is taken out from the camera body 10 in the direction of the arrow B.

In the groove portion of the back lid 30 bent by the groove 32, a resin material (polystyrene), which is a material of the back lid, is bent by bending, and the outer portion is cracked due to stretching of the material. Then, if the bent portion is returned and straightened in order to reuse the case back, the opposite side will be extended this time and a crack will be formed on this side as well. Since the groove 32 of the case back 30 is thin to make it easier to bend, it will be cracked from both sides and many holes will be open and the light will be leaked and the light blocking property will be reduced. Or, the light cannot be shielded and the back cover cannot be reused.

When the back cover bent as described above is reused and the bent portion is returned and straightened,
Since the material is a resin material (polystyrene) as described above, plastic deformation occurs in that part, and when the back cover is attached to the camera body, the back cover rises above the camera body, which causes light leakage. This means that it is impossible to reuse the case back even from this aspect.

Further, when the back cover is removed from the camera body, as described above, the hole 30C of the back cover 30 is removed from the claw 10K of the camera body 10 through this hole or the engaging portion between the engaging portion and the claw. When a flat-blade, flat-blade screwdriver-like metal fitting is inserted into this and the engagement is released, the bridge portion 301C, which is the engagement piece forming the hole 30C, is thin and the plate thickness is 1.2 mm in this embodiment, so that it is easy to break. Since the bridge portion 301C is broken, the back cover 30 cannot keep the film chamber of the camera body 10 in a light-tight state.

As described above, the back cover 30 cannot be reused, which prevents the user layer from reusing only the film with a new film that has not been exposed and reuses the camera. After checking and confirming the guarantee of quality, a new film is loaded, and a new back cover is attached by the dedicated jig to be provided to the user.

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-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 a cartridge chamber 15 as two accommodating chambers for film winding and film loading in the same plane on both sides of the screen frame 16 which is the exposure unit.
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 of 130 to 140 μm, which is the same as a general camera, and a spool of the cartridge P1 is previously stored in a dark room or the like using the cartridge as a container. 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, and a film of a certain length has come out from the film outlet of the cartridge P1. The film in this state will be loaded into the camera. The loading method will be described below.

The cartridge P1 is loaded into the cartridge chamber 15A so that the spool S1 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 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.

In the camera body 10, 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 turning 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 one per piece having a length of eight perforations, which is the number of teeth of the sprocket gear, and the piece size is a so-called full size piece 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 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 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 lock, 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 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 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 clockwise by the spring force of the hoisting stopper spring 58, but the arm portion 61A of the charge lever 61 is
It is stopped by the end face of A and stops, and the V-shaped projection at the tip of the hoisting stopper 57 does not lock the ratchet gear 51A of the hoisting 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 formed by the projecting portion 61 of the charge lever 61 by the next film winding after the photographing of a predetermined number of frames 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 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.

In this way, in the present embodiment, when the 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 62
D jumps into the groove 55A of the cam 55, the winding stopper 57 is disengaged, and 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.
