Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a film-integrated camera in which an unexposed film is loaded in advance in a camera (imaging mechanism) having exposure and film winding functions.

[0002]

2. Description of the Related Art Generally, a film-integrated camera of this type is used only for shooting one pre-loaded film, and as a general rule, the film and the camera are integrally brought into a print shop after the shooting is completed. Has become. Then, the film is taken out at the manufacturer's factory (or the developing lab), and the camera body is disposed of or partially recycled. Therefore, the mechanism of each part of the camera body is extremely simple, and is configured to be manufactured at low cost.

For example, in the conventional image pickup lens pressing portion of the film-integrated camera, the lens holding frame 1 is attached to the guide pin 101A provided on the support member 101 of the image pickup lens.
So that the lens can be finally fixed by press-fitting the fork-shaped slidable member 102A provided on the No. 02, and by additionally pressing the lens pressing frame 102 with the front cover of the main body. It was composed (Fig. 8).

Since the film-integrated camera is often used by purchasing it while traveling and carrying it in a chest pocket of a shirt, the external dimensions are 110 × 6.
It was constructed as small as 0 × 30 mm. in this case,
In order to prevent the fingertips of the photographer from entering the visual field area of the photographing lens, a protrusion for suspending the fingertips is provided in the grip area of the front cover.

[0005]

The film-integrated type camera as described above, in view of the increasing resource and environmental protection concept,
There is a growing demand for a shift from the original “disposable camera” to a “shooting-only camera” (reuse camera) that can positively reuse part or all of the imaging mechanism.

[0006] In such a new trend, the conventional film-integrated camera has a drawback that it is not suitable for reuse. For example, in the lens pressing part, the structure in which the lens is fixed by press-fitting the sliding member to the guide pin and pressing the front cover is as follows: -Without mounting the front cover, the lens is easily separated from the support member, Trouble at the recycling stage is likely to occur.-When the lens only is recycled and replaced, there is a problem that the press-fitted state of the guide pin and the sliding member may become loose.

In addition, the structure in which the convex portion is attached to the front cover is as follows: the step of attaching the convex portion is wasteful, the number of parts is large, and the configuration is complicated. However, there is a problem that the visual field of the fingertip beyond the convex portion is likely to occur.

In view of the above points, it is a first object of the present invention to provide a film-integrated camera having a lens pressing unit which is easy to assemble and can be recycled. A second object of the present invention is to provide a film-integrated camera capable of reliably preventing the fingertip from entering the visual field with a simple structure. A third object of the present invention is to provide a film-integrated camera capable of reducing the number of parts of members involved in preventing the visual field penetration of a fingertip and simplifying the assembly process.

[0009]

To achieve the above object, the present invention is capable of fixing a supporting member for supporting an image pickup lens and a peripheral portion of the image pickup lens in the optical axis direction so as to be fixed to the supporting member. In a film-integrated type camera including a lens pressing member, the lens pressing member is provided with an elastic claw member that can enter the hole of the support member while being flexibly deformed at the time of pressing and can be locked on the back side of the support member, By simply pressing the lens pressing member from one direction, the lens can be securely fixed without auxiliary pressing by the front cover.

Further, in the grip area on the release button side of the front cover, a concave portion capable of suspending fingertips is provided, and a convex portion having a wall surface that continuously rises is provided on the wall surface of the concave portion on the imaging lens side, It is possible to prevent the fingertip from entering the photographing field of view beyond the concave portion. Further, the concave portion and the convex portion are formed integrally with the front cover, so that the number of parts can be reduced and the assembling process can be simplified.

[0011]

When the image pickup lens is set in the lens accommodating portion of the support member and the lens is pressed from one direction by the lens pressing member, the elastic claw member enters the hole of the support member while flexibly deforming, and then when the lens pressing is completed. , Lock on the back side of the support member. At this stage, the lens pressing member does not come off unless the elastic claw member is unlocked, so there is no risk of the lens coming off during the assembly work. Also,
Unlike the conventional camera, it is not necessary to press the lens pressing member with the front cover.

In the assembled film-integrated camera, a concave portion capable of catching the fingertips of the photographer's hand on the release button-side gripping region of the front cover (usually the region on the right side as viewed from the photographer's side). It is provided integrally. Therefore, if the user holds the camera during shooting, the fingertip (middle finger or ring finger) enters the concave portion to obtain a grip feeling, and the movement of the fingertip that attempts to move to the photographing lens side beyond the concave portion is caused by the concave lens side of the imaging lens. Is blocked by a convex portion having a continuous wall surface continuous with the wall surface of.

A portion 20B (a member corresponding to a decorative cover in a conventional camera) is integrally formed and projects with a thickness of about 8 mm from the plate surface of the front cover 20. Also,
The front cover 20 is provided with a recessed portion 20C on the side of the release button 25 (on the right-handed camera, on the right side when viewed from the photographer, on the right-handed side, on the left side in the case of a right-handed camera) in which a fingertip can be locked, and A convex portion 20E having a continuous wall surface 20D continuous with the wall surface of the image pickup lens side of 20C is provided (FIGS. 1, 2, and 5). A gap is provided between the convex portion 20E and the protruding portion 20B so that a part of the carton 200 can enter. The convex portion 20E has a triangular shape when viewed from the front, and the apex thereof is on the concave portion 20C side so that the feeling of collision with the fingertip becomes remarkable. That is, when the photographer puts his / her index finger on the release button 25,
The fingertips of the middle finger or the ring finger are hooked in the recesses 20C (creating a grip feeling by this), and moreover, the fingertips pass over the recesses 20C and enter the imaging lens side.
With 0E, it is possible to prevent (create a feeling of collision with a fingertip).

Here, the concave portion 20C, the convex portion 20E and the projecting portion 20B are formed integrally with the front cover 20, so that the number of parts can be reduced and the assembling process can be simplified. . The front cover 20 further has a viewfinder eyepiece lens 23 and an objective lens 2 on the back surface.

In No. 0, a cartridge P1 and a spool S2 in which the leading end of the unexposed film F is locked are mounted in a cartridge chamber and a scroll chamber (both not shown) formed on the back surface thereof.

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 is possible to be caught in the cartridge P1 every time the photographing is completed. A back cover 30 is attached to the back surface of the camera body 10 in which the film F is loaded so that the film F is protected from light and the focus surface position is restricted.

The back cover 30 has nails 30A and 3 on its front surface.

When mounting on the camera body 10, the claws 30A and 30B are attached to the locking portions 10H and 10J of the camera body 10, while the holes 3
0C and 30D are engaged and fixed to the claws 10K and 10K of the camera body 10, respectively. After the back cover 30 is attached, a predetermined film winding operation is performed to set a photographable screen, and the carton 200 shown in FIG. 1 is attached and completed.

Next, the film winding mechanism 50,
Details of the sector 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 body, while FIG. 6 shows at an angle when viewed from the side of inserting the film-wrapped cartridge and spool into the camera body. Is.

The camera body 10 is provided with a cartridge chamber 15A and a scroll chamber 15B as two accommodating chambers for film winding and film loading in the same plane on both sides of the screen frame 16 which is an exposure unit. The J135 film F wound around the cartridge P1 which is the storage container shown in FIG. 6 is loaded.

Film F used in the camera of this embodiment
Like a general camera, a roll film J135 or a slightly thin roll film of 130 to 140 μm is taken in a predetermined number of frames by previously fixing the end portion to the spool S1 of the cartridge P1 in a dark room or the like using the cartridge as a container. The film is wound as much as possible, and a film having a certain length is taken out from the film drawing port of the cartridge P1.
I will load the film in this state into the camera,
The loading method will be described below.

Put the cartridge P1 in the cartridge chamber 15A,
The spool S1 of the Patrone P1 is the winding fork 5
It is loaded so as to engage with the two forks of No. 2. On the other hand, the spool S2 is also inserted in the scroll chamber 15B. Then, in the present embodiment, the film F until the tip of the film notcher FN of the film F is aligned with the index of the lower portion of the lower rail surface.
Is pulled out, the tip of the film F is inserted into the slit SL of the spool S2, and the perforation P of the film F is locked to the claw H. Incidentally, the film notcher FN is such that the emulsion lot number of the film is indicated by several holes provided in the tongue portion at the tip of the film.

Then, the back cover 30 is covered and the cover is made light-tight. Then, the main camera in this state is attached to a dedicated tool that is a film winding device, and the entire film F (however, the other end is a range where it does not separate from the spool S1 of the cartridge P1) is wound onto the spool S2 of the scroll chamber 15B. Will be loaded. That is, by loading the film F in this way, the film F is sequentially wound into the patrone P1 for each photographing,
After the photographing of a predetermined number of images is completed, in this embodiment, 2
When the frame is fed in the air, the leading end of the film F is wound into the cartridge P1. Therefore, this cartridge can be taken out from this camera in a bright room.

Here, a special tool which is a film winding device will be described. The dedicated tool has the following five functions, and these functions will be described with reference to FIGS. 7 (a) and 7 (b). FIG. 7A is an explanatory diagram for releasing the locking mechanism of the film winding mechanism 50 of the camera. Figure 7
In (a), PA is a tapered pin that becomes thinner toward the tip, and as shown, the front cover 20 and the back cover 3
Pins A and PA are to be inserted through each hole formed by 0. The pins A and PA are ratchet gears 5 provided on the circumferential surface of the film winding knob 51.
The reverse rotation preventing claw 53 which is engaged with 1A and blocks the clockwise rotation of the film winding knob 51 is separated by the ratchet gear 51A as shown in the drawing, thereby enabling the clockwise rotation of the film winding knob 51. It has a function.

Next, PB is inserted through the hole provided in the back cover 30, and the groove 55A provided in the cam 55 as shown in the drawing.
The pins B and PB have the function of allowing the cam 55 to rotate freely by inserting the pins as shown in the drawing. The dedicated tool also has a function of holding the charge lever 61 (not shown) in a charged state and a sensor function of counting the number of rotations of the cam 55.

FIG. 7B is an explanatory diagram of film winding on the spool S2 in the scroll chamber 15B. Figure 7
In (b), CP is a coupling that meshes with the winding claw under the spool S2 of the scroll chamber 15B,
The spool S2 is rotated by the power of a motor or the like in the direction of the arrow and counts the number of rotations of the cam 55 coaxial with the sprocket gear that meshes with the film.
It has a function of winding the film F so that both sides of the film F are wound into the above-mentioned state.

By attaching this camera to a special tool which is a film winding device having such five functions, this camera can extremely easily load a film in a bright room. In this camera, the spool S2 is rotated by the power of a motor or the like to wind the film in a state in which the locking of the film winding mechanism 50 by the reverse rotation preventing claw 53, the cam stopper 62 and the charge lever 61 is released. Because,
For loading a film in a bright room, it is impossible to load the film without this special tool.

Next, the mechanism of the main body will be described. The camera body 10 incorporates the film winding mechanism 50 including the photographing lens 12, a sector charge mechanism 60, and a film counter mechanism 70 as main components.

First, the film winding mechanism and the sector charge mechanism will be described. Reference numeral 51 denotes 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 having a fan-shaped cam portion 55B at the lower portion, which is coaxial with the sprocket gear 54 having eight teeth and which meshes with the perforation P of the film F, is adapted 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. Due to the counterclockwise rotation of the cam 55, as described above, the fan-shaped cam portion 5 is naturally operated.
5B also rotates counterclockwise and, in the process, the fan-shaped cam 55
B to charge lever 61, charge lever shaft 63
Rotating in the clockwise direction against the spring force of the charge lever spring 64 that urges the charge lever 61 in the counterclockwise direction, and the triangle-shaped ketobashi 61C provided on the charge lever 61 causes the rising portion 65B of the sector lever 65 to rise. Press
Eventually, the vehicle rises over the rising portion 65B and charges the sector charge mechanism as shown in the figure.

A sector spring 67 is stretched between the pin 65C of the sector lever 65 and the pin 18C provided on the camera body 10. The sector spring 67 pulls the sector spring 67 so that the sector lever 65 can slide and rotate in the elongated hole. The arm plate 65 that abuts the left end of the elongated hole on the pin 18B provided on the camera body 10 and that is provided on the sector lever 65.
D is brought into contact with a pin 18E provided on the camera body. In addition, the sector pin 1 provided on the camera body 10
By 8D, the sector drive pin 65A for operating the axially supported sector 66 is inserted into the two-forked part of the sector 66.

As will be described later, the projecting portion 62D of the cam stopper 62 after the end of photographing is removed by the groove portion 55A of the cam 55, and the arm portion 57A of the winding stopper 57 changes from the state shown in the drawing to change the state of the charge lever 61. Arm 61A
Also, the cam stopper 62 comes in contact with the end face of the arm portion 61A by the spring force of the winding stopper spring 58 that is displaced from each edge of the arm portion 62A and is biased in the clockwise direction. 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 for biasing the cam stopper 62 by the horizontal end portion of the charge lever spring 64 in the clockwise direction. Therefore, at the time of the protruding portion 62 of the cam stopper 62,
The arm 57A of the winding stopper 57, which has been locked to the end surface of the arm 62A, is released.

The outer peripheral cylindrical surface of the film winding knob 51 is a ratchet gear, and due to the release of the lock, the tip V-shaped projection of the winding stopper 57 is caused by the spring force of the winding stopper spring 58 to the ratchet gear. It jumps into the tooth space of 51A 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 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. Has become.

By pressing the release button 25 of the front cover 20, the tip of the release button pin 25A implanted 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 arrow A marked on the winding knob 51 in FIG.
By the operation of the tip of the release button pin 25 in the direction, the winding stopper 57 rotates counterclockwise against the spring force of the winding stopper spring 58. Then, the edge of the arm portion 61A of the charge lever 61 is disengaged from the end face of the winding stopper 57, 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.
1C hits the rising portion 65B of the sector lever 65, and then comes off the rising portion 65B. Therefore, the sector lever 65 has the pin 18B in the long groove of the sector lever.
Rotates clockwise around the sector spring 67 against the pulling force of the sector spring 67, and then returns to the original state by the pulling force of the sector spring 67. Therefore, the sector drive pin 65A is connected to the sector 6
6 is rotated about the sector pin 18D to expose the film, and then the film is closed.

On the other hand, the cam stopper 62 also rotates counterclockwise together with the charge lever 61 as described above, and the protruding portion 62D of the cam stopper 62 comes out of the groove portion 55A of the cam 55. Therefore, even if the release button 25 is not pressed, the arm portion 57A of the winding stopper 57 is urged clockwise by the spring force of the winding stopper spring 58, but is blocked by the end face of the arm portion 61A of the charge lever 61. Stop, V of the tip of the winding stopper 57
The shaped protrusion does not lock the ratchet gear 51A of the winding knob 51. Therefore, the next film can be wound up.

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 the film 1
It is an exponential gear that rotates clockwise one tooth each time the frame is wound up and the cam shaft 56 makes one rotation.

An index plate 71 is printed as an integrally molded product on the upper surface of the index wheel gear 72, and the number of remaining photographable films is displayed by the film counter window 26 on the upper surface of the front cover 20. . A protrusion 72A is provided on the lower surface of the index wheel gear 72, and the next protrusion of the film after the filming of a predetermined number of frames is completed causes the protrusion 72A to be a protrusion of the charge lever 61 and another protrusion of the cam stopper 62. It is designed to break in between 62E. When the protrusion 72A is inserted between the protrusions 61E 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, the protrusions 61E and 62E are removed. The protrusion 72A of the index plate gear 72 prevents the charge lever 61 from moving, and the protrusion 62D of the cam stopper 62 cannot jump into the groove 55A of the cam 55. Then, the arm portion 57A of the winding stopper 57 contacts the end surface of the arm portion 67A of the cam stopper 62 by the spring force of the winding stopper spring 58, and the V-shaped protrusion at the tip of the winding stopper 57 locks the ratchet gear 51A. It is also 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 the idle mode, the index plate gear 72 moves to two.
Although the teeth rotate, the protrusion 72A of the exponential gear 72 still presses the protrusion 61E to prevent the movement of the charge lever 61, but the protrusion 72A comes off from another protrusion of the cam stopper 62. ing. Therefore, the protruding portion 62D jumps into the groove portion 55A of the cam 55, the locking of the winding stopper 57 is released, and the winding stopper 57 is released.
The film winding cannot be wound up because the film winding knob 51 is locked by. Further, as described above, since the movement of the charge lever 61 is blocked, the film cannot be exposed. In this way, the tongue at the leading end 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 dimension is used, there is no problem in drawing out the film from the cartridge at the time of development.
