Description

[0001]
[Industrial application fields]
The present invention relates to a lens-fitted film unit that has exposure and film winding functions and can immediately take a picture of a previously loaded unexposed film.
[0002]
[Prior art]
The lens-equipped film unit is a film-integrated camera that has the function of taking a photo, which is also called a “photo-taking camera”, and it is only for taking a picture of a single loaded film as is well known. The camera body is discarded after the used and exposed film is taken out, and is therefore manufactured at a low cost with a simple structure.
[0003]
Cameras are often purchased and used on the road, but it is hard to say that they are convenient to carry around. The camera has a f = 35mm photographic lens and is 110mm x 60mm x 35mm. It was inconvenient without entering the chest pocket of the shirt.
[0004]
[Problems to be solved by the invention]
However, despite the fact that it is a “shooting camera”, the camera function tends to become more sophisticated as in the case of a film unit with a lens built into a strobe light emitting device due to the recent diversification of shooting purposes. Increasing camera size is inevitable.
[0005]
Furthermore, from the viewpoint of reusing resources, there has been a demand for a camera that can be reused, that is, a reusable camera.
[0006]
In order to be able to reuse the camera as it is, it is necessary to recheck the camera for quality assurance, and reuse only by exchanging only the minimum necessary parts ( Cameras that can be reused are being requested.
[0007]
That is, there has been a demand for a reusable camera having means for preventing only the film from being used again without checking the camera. Therefore, if the user can easily take out the cartridge and put in a new cartridge, the camera cannot meet the quality standards of the optical system, the strobe, and the like.
[0008]
Of course, the patrone must be easily removed at a predetermined location (development laboratory or manufacturer), and the reliability must not be reduced by replacing the patrone. Processing for resource reuse Must also be easy.
[0009]
As a result of improving these points, the present invention improves the durability of the locking portion that locks the back cover of the lens-fitted film unit by suppressing the increase in cost by simplifying the mechanism of the camera and utilizing the space, The purpose is to provide a film unit with a lens that promotes reuse.
[0010]
[Means for Solving the Problems]
The purpose of the above is that the film is previously wound in the scroll chamber of the camera body, and the film that has been photographed is sequentially rewound in the cartridge chamber of the camera body, and the cartridge covers the scroll chamber and the cartridge chamber. Up In the lens-fitted film unit that is light-tightly covered with an outer shell portion molded by a plastic, the outer shell portion is a bent portion closer to the scroll chamber than the cartridge chamber and closer to the cartridge chamber than the scroll chamber. The folding part is configured to be bendable at Neighborhood Scroll room Side At the time of folding provided at a position where the cartridge chamber is sandwiched between the folding portion and the latching portion for holding the outer shell portion on the camera body side during folding provided at positions near both ends of the folding portion. This is achieved by a lens-fitted film unit that is locked to the camera body side by a locking portion that releases the locked state to the camera body side.
[0012]
【Example】
FIG. 1 shows the external appearance of the lens-equipped film unit of the present invention (hereinafter also referred to as the present camera). The camera is provided with a 35 mm film (J135) loaded in advance, and rewinding is performed after shooting. Without being done, the film is sent to the developing station while being stored in the camera, the film is taken out from the camera, and the film is developed and printed.
[0013]
The unexposed film used in this camera is loaded by a loading method described later. In the loaded state, the film is wound around the spool from the cartridge, and is wound into the cartridge every time shooting is performed. Therefore, the film which has been photographed can be taken out from the camera in the bright room at the developing station.
[0014]
Also, taking out the photographed film can be easily done by folding a part of the back cover as the outer shell, so check the camera part, load a new unexposed film and replace the back cover. Can be reused.
[0015]
A cartridge having an outer diameter of φ20.6 mm, which is different from a commonly used cartridge (JISK7528), is used as the cartridge loaded in the camera.

[0038]
FIG. 5 is a perspective view of the camera viewed from the back side, and mainly shows the main points in order to make it easy to understand the hook engagement between the back cover and the camera body.
[0039]
In FIG. 5, A 1, B 1, C 1 indicate hook engaging portions that are attached by attaching the back cover 30 to three positions of the camera body 10. The “locking portions that hold the outer shell portion on the camera body side when folded” are the locking portions A1 and B1, and the “locking portions that are unlocked to the camera body side when folded” are related. It is a stop part C1. Of these three hook locking portions, A1 and B1 bend the back cover when a later-described cartridge provided on the back cover is taken out. It is a bent part Of course, it is a hook locking portion that locks the back cover 30 to the camera body 10 provided on the opposite side (scroll chamber side) to the locking portion C1 above and below the groove 32. The hook engaging portions A1 and B1 are provided as a pair at opposite positions, and the X and Z directions are the same in the engaging directions indicated by the arrows, and the Y directions are directed inward in opposite directions. The back cover 30 is locked to the camera body 10 in the direction.
[0040]
The hook locking portion C1 is a hook locking portion that locks the back cover 30 to the camera body 10 at substantially the center of the right position. In the locking direction of the locking portion C1 indicated by an arrow, the X direction is directed inward as in the case of the hook locking portions A1 and B1, and the back cover 30 is locked to the camera body 10. As described above, the back cover 30 is locked to the camera body 10 in at least three positions in three locking directions facing the inside of the camera.
[0041]
Since the hook locking portions A1, B1, and C1 are in such a positional relationship, the back cover 30 is attached to the camera body 10 in a well-balanced manner, and the hook locking portion C1 is hooked when a cartridge that will be described later is taken out. When the back cover 30 is bent at the groove 32 by removing only the back cover 30, the back cover 30 is hooked to the main body 10 by two hook engaging portions A1 and B1 on the left side of the groove 32. Can be easily folded at the position of the groove 32.
[0042]
FIG. 6 is a diagram showing film removal 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, and a minus driver-shaped metal fitting with a sharp tip is inserted into this hole or the engaging part of the locking part and the claw.

The back cover 30 is bent from the groove 32 of the back cover 30 so that the back cover 30 is Push from state to state II. Then, the cartridge P1 in which the film that has been photographed is wound is taken out from the camera body 10 in the arrow B direction.
[0043]
Thus, in this camera, the cartridge can be easily removed by releasing one of the three hook locking portions between the back cover and the camera body and bending the back cover at the groove to open the cartridge chamber side. It can be taken out. This place is easily opened by the lab. However, it is desirable that the remaining two places are impossible in principle.
[0044]
Although not shown in the figure, the remaining two locations are structures that cannot be used unless the specific member is pushed in and removed, and the mechanism cannot be opened unless it is a special jig (owned only by the manufacturer). It can be.
[0045]
FIG. 7 is a diagram showing another embodiment.
[0046]
FIG. 7 is a perspective view of the camera as seen from the back side, as in the case of FIG. 5, in order to make it easier to understand the hook engagement between the back cover and the camera body. It is shown.
[0047]
In FIG. 7, A2, B2, C2, and D indicate hook engaging portions that are attached by attaching the back cover 30 to the four positions of the camera body 10. Of these four hook engaging portions, A2 and B2 are provided with a back cover 30 on the camera body 10 above and below the groove 32 that bends the back cover when the cartridge provided on the back cover is taken out as in the case of FIG. It is the hook latching part to latch. Note that the cartridge is taken out from the camera in exactly the same way as described in FIG. The hook locking portions A2 and B2 are provided in pairs at opposite positions as in the case of FIG. 5, and among the locking directions indicated by arrows, the X and Z directions are the same and the Y direction is the mutual direction. The back cover 30 is locked to the camera body 10 so as to face inward in the opposite direction.
[0048]
Further, the hook locking portions C2 and D are hook locking portions for locking the back cover 30 to the camera body 10 at substantially the center of the left and right positions. The locking portions C2 and D are provided in pairs at opposite positions like the hook locking portions A2 and B2, and among the locking directions indicated by arrows, the Y and Z directions are the same direction and the X direction. Are inwardly opposite directions and lock the back cover 30 to the camera body 10.
[0049]
As described above, the hook locking portions A2, B2 and C2, D are paired, and the Y direction of the hook locking portions A2, B2 and the hook locking portions C2, D of the pair of locking directions, respectively. The X directions are directed inwardly opposite to each other, and the lines passing through the hook engaging portions A2, B2 and C2, D intersect at substantially right angles. The Y direction of the hook engaging portions A2 and B2 and the X direction of the hook engaging portions C2 and D are in the directions in which the engaging directions are opposite to each other, but are at the crossing at the right angle. Since the hook locking portion is further hook-locked in both the X and Y directions, there is no problem with respect to the hook locking. Since the hook locking portions A2, B2, C2, and D are in such a positional relationship, the back cover 30 is attached to the camera body 10 in a balanced manner, and the hook of the hook locking portion C2 is taken out when the cartridge is taken out. When the back cover 30 is bent in the groove 32 by removing only the lock, the back cover 30 is hook-locked to the main body 10 by three hook lock portions A2, B2, D on the left side of the groove 32. Therefore, the back cover 30 can be easily bent at the position of the groove 32.
[0050]
As described above, in this camera, the cartridge can be easily removed by releasing one of the four hook locking portions between the back cover and the camera body and bending the back cover at the groove to open the cartridge chamber side. It can be taken out.
[0051]
And since the back cover is locked to the camera body in more than three directions, a special jig is required to attach the back cover, and the user cannot easily attach or detach the back cover, and therefore the film cannot be replaced. .
[0052]
The camera with the cartridge removed in this way is sent to the manufacturer side with the back cover attached, and the back cover is removed here by removing the remaining three hooks, and further functions as a camera. The performance is checked. Then, a cartridge in which a new unexposed film is wound is loaded into the passed camera by a loading method to be described later, a new back cover is mounted, and the camera is ready to be photographed and provided to the user.
[0053]
As described above, the back cover is attached to the camera body after the cartridge is taken out at the developing station until it is removed at the manufacturer side.
[0054]
Therefore, if the back cover that has been removed from the cartridge is half-opened, it can be easily removed from the camera body until it returns to the maker side from the development station. It will be dissipated and become a problem from the point of resource reuse. However, in the case of this embodiment, even after the cartridge is taken out, the back cover is locked to the main body particularly at three places, so that it does not easily come off.
[0055]
In this way, the latching portion between the back cover and the camera body is first removed from the four places at the developing place, and the cartridge is taken out. Then, it is sent to the manufacturer side, where the remaining three locking portions are removed and the back cover is removed from the camera body. That is, the back cover is removed to replace the back cover. And this hook latching part may be four or more places, and removal of the latching part when taking out a cartridge may be one or more places. Although the camera body is reused, the back cover is used only once, so that the part on the main body side where the back cover is hooked to the camera body is easily damaged. Therefore, the resin material of the back cover is preferably softer than the camera body.
[0056]
Further, the removal of the cartridge is not limited to the method of removing the back cover by folding, and the outer casing part may be folded and taken out, for example, the side wall or the bottom wall may be bent and taken out.
[0057]
Details of the film winding mechanism 50, the sector charge mechanism 60, and the film counter mechanism 70 will be described below.
[0058]
FIG. 3 shows the mechanisms as seen from the back side of the camera, and FIG. 4 shows the angles of the cartridge and spool in which the film is wound, as seen from the direction of insertion into the camera body. is there.
[0059]
The camera body 10 is provided with a cartridge chamber 15A and a scroll chamber 15B as two storage chambers for film winding and film loading in the same plane on both sides of the screen frame 16 as an exposure unit. The J135 film F wound in the cartridge P1 which is the storage container shown in FIG. 4 is loaded.
[0060]
The film F used for the camera of this embodiment is a roll film J135 or a slightly thin roll film having a thickness of 130 to 140 μm as in a general camera. The film F is placed on the spool S1 of the cartridge P1 in a dark room or the like in advance using the cartridge as a storage container. The end is fixed, and a predetermined number of frames are rolled in such a length that can be photographed, and a film of a certain length comes out from the film outlet of the cartridge P1. The film in this state is loaded into the camera. The loading method will be described next.
[0061]
The cartridge P1 is loaded into the cartridge chamber 15A so that the spool S1 of the cartridge P1 is engaged with the bifurcated portion of the hoisting fork 52. On the other hand, the spool S2 is also inserted into the scroll chamber 15B. In this embodiment, the film F is pulled out until the leading end of the film notch FN of the film F matches the index 17A on the lower side of the lower rail surface, and the leading end of the film F is inserted into the slit SL of the spool S2 to The perforation P is locked to the nail H. The film notch FN displays the emulsion lot number and the like of the film by several holes provided in the tongue at the front end of the film.
[0062]
Next, the back cover 30 is put on the cover to make it light tight. The camera in this state is attached to the film take-up device, and the entire film F (with the other end not being detached from the spool S1 of the cartridge P1) is taken up on the spool S2 of the scroll chamber 15B to finish the film loading. It will be. That is, by loading the film F in this way, the film F is sequentially wound into the cartridge P1 every time shooting is performed. After shooting a predetermined number of frames, in this embodiment, two frames are skipped. Then, the film-finished film is wound into the cartridge P1, leaving the necessary length without the front end of the film F being wound into the cartridge. Therefore, this cartridge can be taken out from the camera in a bright room.
[0063]
Next, the mechanism of the main body will be described.
[0064]
The camera body 10 incorporates the film winding mechanism 50 including the photographing lens 12, the sector charge mechanism 60, and the main mechanisms of the film counter mechanism 70.
[0065]
First, the film winding mechanism and the sector charge mechanism will be described.
[0066]
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 having a fan-shaped cam portion 55B at the lower portion, which is coaxial with the eight-tooth sprocket gear 54 meshing with the perforation P of the film F, rotates exactly once in the counterclockwise direction when the film is wound up.
[0067]
In other words, the film is rolled up with the length of 8 perforations as 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.
[0068]
Due to the counterclockwise rotation of the cam 55, the fan-shaped cam portion 55B naturally rotates counterclockwise as described above, and in the process, the charge lever 61 and the charge lever shaft 63 are rotated by the fan-shaped cam portion 55B. The charge lever spring 64 is rotated clockwise against the spring force of the charge lever spring 64, and the rising portion 65B of the sector lever 65 is pressed by the triangular kettle 61C provided on the charge lever 61. Eventually, over the rising portion 65B, the sector charge mechanism is charged as shown.
[0069]
A sector spring 67 is stretched between a pin 65C of the sector lever 65 and a pin 18C provided on the camera body 10, and the slot hole of the sector lever 65 is slidably guided by the tensile force of the sector spring 67. The left end of the elongated hole is brought into contact with a pin 18B provided in the camera body 10, and an arm plate 65D provided in the sector lever 65 is brought into contact with a pin 18E provided in the camera body 10. A sector drive pin 65A for operating the sector 66 pivotally supported by a sector pin 18D provided in the camera body 10 is inserted into the bifurcated portion of the sector 66.
[0070]
As will be described later, the projecting portion 62D of the cam stopper 62 after the photographing is finished is disengaged from the groove portion 55A of the cam 55, and the arm portion 57A of the hoisting stopper 57 changes from the state shown in FIG. 61A and the arm portion 62A of the cam stopper 62 are separated from the respective edges, and are in contact with the end surface of the arm portion 61A by the spring force of the hoisting stopper spring 58 biased in the clockwise direction. Then, when the cam 55 is rotated once as described above by the film winding and the groove 55A of the cam 55 returns to the initial position, the spring force for urging the cam stopper 62 by the horizontal portion at the tip of the charge lever spring 64 in the clockwise direction. As a result, the protrusion 62D of the cam stopper 62 jumps into the groove 55A. As a result of this dive operation, the arm portion 57A of the hoisting stopper 57 that has been locked to the end surface of the arm portion 62A of the cam stopper 62 at this time is released.
[0071]
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 moved by the spring force of the winding stopper spring 58 due to the release of the locking. It jumps into the tooth gap and prevents the film winding knob 51 from rotating counterclockwise. That is, when the film winding is completed, the film winding knob 51 is prevented from rotating further.
[0072]
Further, the camera body 10 has a tip of a reverse rotation preventing claw 53 utilizing the elasticity of the resin material pressed against the ratchet gear 51A, and prevents the film winding knob 51 from rotating in the opposite direction to the winding. Yes.
[0073]
When the release button 25 of the front cover 20 is pressed, the tip of the release button pin 25A planted on the back surface of the release button 25 operates in the direction of arrow A. That is, when the front cover 20 is attached to the camera body 10, the hoisting stopper 57 is actuated by the action of the tip of the release button pin 25 in the direction of arrow A indicated on the hoisting knob 51 in the figure. Rotates counterclockwise against force. Then, the edge of the arm portion 61A of the charge lever 61 is removed from the end surface of the arm portion 57A of the hoisting stopper 57, and the charge lever 61, and therefore the cam stopper 62 is rotated counterclockwise by the spring force of the charge lever spring 64.
[0074]
Then, due to the counterclockwise rotation of the charge lever 61 by the spring force of the charge lever spring 64 stronger than the sector spring 67, the kettle 61C of the charge lever 61 strikes the rising portion 65B of the sector lever 65, and from the rising portion 65B. Come off. Accordingly, 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 returns to the original state by the tensile force of the sector spring 67. Accordingly, the sector drive pin 65A is closed after the sector 66 is rotated around the sector pin 18D to expose the film.
[0075]
On the other hand, the cam stopper 62 also rotates counterclockwise together with the charge lever 61 as described above, and the protrusion 62D of the cam stopper 62 comes out of the groove 55A of the cam 55. Therefore, even if the release button is stopped, the arm portion 57A of the hoisting stopper 57 is urged clockwise by the spring force of the hoisting stopper spring 58, but is blocked by the end surface of the arm portion 61A of the charge lever 61. The V-shaped protrusion 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.
[0076]
Next, the film counter mechanism will be described.
[0077]
As described above, 72 meshes with the V groove 56A provided at the upper end of the cam shaft 56 implanted in the cam 55 that rotates integrally with the sprocket gear 54, and the film is wound up by one frame so that the cam shaft 56 is 1 This is an index wheel that rotates clockwise one tooth each time it rotates.
[0078]
An index board 71 is printed on the top face of the index board gear 72 as an integrally molded product, and the remaining number of film shootable images is displayed from the film counter window 26 on the top face of the front cover 20.
[0079]
A protrusion 72A is provided on the lower surface of the index wheel 72, and the protrusion 72A is separated from the protrusion 61E of the charge lever 61 and another protrusion of the cam stopper 62 by the next film winding after the photographing of the predetermined number of frames is completed. It breaks between 62E and enters. When the protrusion 72A enters between the protrusions 61E and 62E, the film is wound up by one frame, and the protrusions 61E and 62E remain even if the cam 55 rotates once and the sector is charged. The movement is prevented by the protrusion 72A of the index wheel 72, so that the charge lever 61 cannot be operated, and the protrusion 62D of the cam stopper 62 cannot jump into the groove 55A of the cam 55. The arm portion 57A of the hoisting stopper 57 abuts on 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 protrusion at the tip of the hoisting stopper 57 locks the ratchet gear 51A. Neither can the charge lever 61 be operated to open or close the sector to expose the film.
[0080]
In this way, in the present embodiment, when the two frames of film are fed forward, the index wheel gear 72 rotates by two teeth. By this rotation, the protruding portion 72A of the index wheel gear 72 causes the protruding portion 61E to rotate. Although the movement of the charge lever 61 is blocked by pressing the cam stopper 62, the cam lever 62 is disengaged from the other protrusion 62E. Accordingly, the protruding portion 62D jumps into the groove portion 55A of the cam 55, the winding stopper 57 is unlocked and the winding knob 51 is locked by the winding stopper 57, and the film cannot be wound. Since the movement of the charge lever 61 is blocked as described above, the film cannot be exposed. In this way, it is prevented that the film at the front end of the film is caught in the cartridge, and the film having the required length is secured. Therefore, in order to make the camera compact, there is no problem in pulling out the film from the cartridge during development even if a cartridge having a small outer diameter is used.
[0081]
