Description

BACKGROUND OF THE INVENTION [0001] TECHNICAL FIELD OF THE INVENTION This invention relates to a film-integrated camera, and its method of manufacturing have the loaded film by manufacturers such as disposable camera. 2. Description of the Related Art In general, a film cartridge incorporating a 110 type or 126 type film is used in a film-integrated camera of this type. This is to reduce the size of the camera body. However, in such a type of film, since the area of one frame is small, 35 mm
When an image photographed on a full-size screen (24 mm × 36 mm) of a film was compared with a printed image after enlargement, it was inevitable that the film was inferior in sharpness, graininess, and the like. For this reason, 35 mm film (roll film J1
35 [JISK7519] to a special patrone [JI
SK7528] in a light-tight state. [0003] However, in spite of such a film-integrated camera, since the minimum mechanism necessary for photographing must be mounted, the appearance of the camera body itself is
It is not much different from a normal interchangeable film camera.
As long as a patrone containing a 5 mm film is used, there has been a limit to miniaturization. That is, 35m to this kind of camera
In order to use the patrone with m-film, the patrone is loaded into the rewinding chamber in the camera body, and a light-tight empty film container (or an empty patrone) that can store the film is loaded into the hoisting chamber. It is necessary to wind up the photographed film in the empty film container in the winding room and finally take out the photographed film together with the film container when the camera is broken so that the film can be processed. [0004] However, as long as such a film container is used, a winding mechanism for the film container loaded in the winding chamber is inevitably required, and the winding mechanism requires a large installation space. Is required, and the space causes an increase in the vertical dimension of the camera body. [0005] The present invention aims at view of the above, provided to the film-integrated camera to be omitted installation space portion of winding mechanism of the spool of the film container, and a method for producing it. SUMMARY OF THE INVENTION In order to achieve the above object, the present invention relates to a method in which an unexposed film is

It was configured so that the inside could be shielded from light. Next, the method of the present invention will be described with reference to the accompanying drawings. Reference numeral 11 denotes a camera body. The camera body 11 is formed by independently molding and combining a front frame 11a and a back frame 11b. Inside the camera body 11, an exposure chamber a is wound around the exposure chamber a. A return chamber b and a hoisting chamber c are provided. Before the camera body 11 is combined, the first film container 12 containing the 35 mm film is loaded into the rewinding chamber b, and the empty second film container 13 capable of winding the film is wound up. Install in room c. In this case, the draw-out end of the film 15 drawn from the first film container 12 is connected to the spool 14 in the second film container 13 and wound in advance. Further, the spool 1 of the second film container 13
The shaft 16a of the hoisting knob 16 is directly connected to 4 and the head 16b of the hoisting knob 16 is attached to the outside of the camera main body 11 through the through hole 19 provided on the dividing line on the upper surface when the camera main body 11 is combined. Exposure to Shaft 16a of hoisting knob 16
A rib 17 is provided on the outer peripheral surface of the lower end portion along the axial direction. The rib 17 engages with the projections 14a and 14b provided at positions opposed to the inner peripheral surface of the spool 14 by simply inserting them as shown in FIG. After the engagement, it does not slip in the rotational direction. The hoisting knob 16 is for rotating the spool 14 only in the hoisting direction to transfer the film from the first film container 12 to the second film container 13. Ratchet gear to prevent reverse winding (the ratchet pawl is not shown)
18 is fixed. The ratchet gear 18 is also free in the axial direction, but does not slip in the rotational direction. The first and second film containers 12, 13
Have a light-tight structure, and a film-containing patrone and an empty patrone having the same shape may be used as they are. In this case, the film in the film-containing patrone is drawn out to the maximum in a dark room or a light-tight device, and the entire length is wound in an empty patrone in an unexposed state. It is preferable to use the empty film cartridge side as the second film container 13 as the container 12. The film cartridge containing the film used as the first film container 12 is such that the inner end (end) of the film is not fixed to the core (spool), and the whole wound film is transferred into the empty cartridge. It is to be able to do it. Although not explicitly shown in the drawings, the first film container 12 and the second film container 13 may of course be integrally formed as a cartridge. As described above, before the winding knob 16 is mounted on the spool 14 of the second film container 13 before the second film container 13 is assembled into the camera body 11.
And then connect the second film container 13 to the camera body.

Penetrates into the position of the camera body corresponding to 13 spools 14
A hole 19 is formed. By assembling in this manner, FIG.
The light shielding means between the through hole 19 of the type shown in FIG. 1 and the outer peripheral surface of the shaft portion 16a of the hoisting knob 16 can be simply configured. Between the camera body 11 and the hoisting knob 16 exposed to the outside through the through hole 19 on the upper surface thereof ,
Light blocking means for blocking light entering the main body from the through hole is required. There are various modes of the light shielding means, and FIGS. 1, 3 and 4 show examples. In the case of FIG. 1, annular ribs 21 and 22 are raised concentrically around a through hole 19 provided on the upper surface of the camera body 11,
And 22 are provided on the lower surface of the hoisting knob 16 with concave grooves 23 and 24 which engage in an erected manner to form a maze of light. FIG. 3 shows a shaft portion of the through hole 19 and the hoisting knob 16.
An example of a light shielding means between the outer peripheral surface of the shaft 16a and the outer peripheral surface of the shaft 16a of the hoisting knob 16. This is an example in which an elastic light-shielding plate 26 having a reference numeral 25 is adhered as shown in FIG. 3A so that light can be shielded as shown in FIG. FIG. 4 shows the through hole 19 and the shaft of the hoisting knob 16.
Another example of the light shielding means between the outer peripheral surface of the winding knob 16 and the outer peripheral surface of the shaft portion 16a of the winding knob 16 is provided on the inner peripheral surface of the annular rib 21 raised around the through hole 19 of the camera body 11. This is an example in which a light shielding member (a light shielding cloth or a light shielding sponge) 27 is adhered so that light can be shielded. In the camera body 11,
Needless to say, a mechanism necessary for photographing is incorporated.
Hereinafter, these mechanisms will be described with reference to the schematic diagram shown in FIG. In the drawing, reference numeral 28 denotes a film 1 which is shifted by rotating the winding knob 16 in the winding direction.
Sprocket meshed with perforation P of 5, 2
9 is a cam plate fixed to the shaft of the sprocket 28, and 30 is a shutter charge plate. A pin 29a is provided at a symmetrical position on the upper surface of the cam plate 29. The pin 29a is used to rotate the cam plate 29 halfway (corresponding to the amount of rotation when the film 15 is wound on one screen). Overhang portion 30 of charge plate 30
a, and the shutter charge plate 30 is
1 is moved rightward in FIG. Due to this movement, the notch 30b provided at the end of the shutter charge plate 30 is engaged with the projection 32 'of the release plate 32. This locking is performed before the half rotation of the cam plate 29 is completed, and after this point, the pin 29a is disengaged from the overhang portion 30a of the shutter charge plate 30. Accordingly, the shutter charge plate 30 receives a force in the returning direction due to the action of the tension spring 31.
Unless the release plate 32 is pressed to release the lock, the state (shutter charge state) is maintained. At this time, since a step (not shown) provided at a symmetrical position on the outer periphery of the cam plate 29 is engaged with a stopper (not shown), the winding knob 16 is prevented from further turning. When the release plate 32 is pressed and the shutter charge plate 30 returns to the initial position, the stopper comes off the step in the process. The shutter charge plate 30 is provided with a shutter hitting piece 30c pivotally supported so as to be rotatable only clockwise, so that the shutter charge plate 30 moves rightward. When the shutter hitting piece 30c hits a pin on the head of the shutter blade 34 that blocks the optical path of the photographing lens 33, the shutter hitting piece 30c rotates over the pin and rides over the pin. Accordingly, when the release plate 32 is pressed and the shutter charge plate 30 returns from the charge position by the action of the tension spring 31, the shutter hitting piece 30c hits the pin on the head of the shutter blade 34 in the process. As a result, the shutter blade 34
After opening the optical path of the taking lens 33 by rotating
By the action of the return spring 36, the original state is quickly restored. Reference numeral 37 denotes a counter window for displaying the number of film shots (or remaining number). In the counter window 37, a scale of an index plate (not shown) that rotates by one scale every time a gear (not shown) that rotates in connection with the sprocket 28 makes a half turn is exposed. 38 is a simple direct view finder. In the above embodiment, when the photographing of a predetermined number of screens has been completed, all the films are stored in the light-tight second film container 13, so that the camera body 11 is broken by an appropriate method and Can be taken out. You can do this in a light room. As described above, the film of the present invention
