Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a film-integrated camera (hereinafter referred to as “camera”) that is loaded with a film by a manufacturer.
It is about.

[Background of the Invention]

Generally, a film cartridge containing 110 type or 126 type film is used in this type of camera. This is to downsize the camera body, but since the area of one frame is small in such a type of film, it is an image taken with a full size screen (24 mm × 36) of 35 mm film and a printed image after stretching. When compared, it was unavoidable that the sharpness and graininess were inferior.
Therefore, the 35mm film (roll film J135 [JISK75
It was desired to develop a simple camera that can be used as a special cartridge (JIS K7528) stored in a light tight state).

However, since such a simple camera and 雖 must also be equipped with the minimum mechanism necessary for taking a picture,
The external appearance of the camera itself is not much different from that of a normal film interchangeable type camera, so there was naturally a limit to miniaturization as long as a 35mm film patrone was used.
That is, in order to use a 35 mm film cartridge in this type of camera, the cartridge is loaded into the film storage chamber, and a light-tight empty film container (which may be an empty cartridge) that can store the film is also wound in the winding chamber. To the
It is necessary to roll up the photographed film in an empty film container in the winding chamber and take out the photographed film together with the film container for development processing when the camera is finally broken. 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 this winding mechanism requires a large installation space, and the installation space is equivalent to the camera body. Caused a large vertical dimension.

[Object of the Invention]

In view of the above points, the present invention has made it possible to reduce the size of the camera body using a 35 mm film cartridge by omitting the installation space for the coupling mechanism of the spool of the film container and the winding knob. The purpose is to provide a camera.

[Structure of Invention]

This invention relates to a film-integrated camera in which an unexposed film is loaded in a film storage chamber in advance, and the film is wound up on a spool of the film winding chamber for each shooting and the film that has been shot is taken out after the shooting is finished. An opening corresponding to the spool in the chamber is formed on the upper surface of the chamber, and a shaft of a winding knob for winding the film from the film storage chamber to the spool in the film winding chamber is directly formed on the spool so that the final race can be performed. A spool is provided between the upper surface of the hoisting chamber and the lower surface of the hoisting knob so that the spool of the film container and the hoisting knob can be directly connected while maintaining the light shielding performance. Is.

〔Example〕

Next, the present invention will be described based on an embodiment shown in the accompanying drawings.

Reference numeral 11 denotes a camera body. The camera body 11 is formed by independently molding a front surface frame body 11a and a rear surface frame body 11b and combining them, and inside thereof, an exposure chamber a and a rewinding device sandwiching the exposure chamber a are rewound. A room film storage room b and a hoisting room c are provided. Before the camera body 11 is combined, the rewinding chamber b is loaded with the first film container 12 containing the 35 mm film, and the empty second film container 13 in which the film can be wound is loaded in the hoisting chamber c. Incorporate. In this case, the pull-out end of the film 15 pulled out from the first film container 12 in advance is connected to the spool 14 in the second film container 13 and wound. Further, the shaft portion 16a of the hoisting knob 16 is directly connected to the spool 14 of the second film container 13, and when the camera body 11 is united, the hoisting knob is passed through the through hole opening 19 provided on the dividing line on the upper surface thereof. 16
The head 16b of the is exposed to the outside of the camera body 11.

The first and second film containers 12 and 13 each have a light-tight structure, and a film-filled film cartridge and an empty film cartridge of the same shape may be used as they are. In this case, the film in the filmed film cartridge is pulled out to the maximum limit in a dark room or a light-tight device, and the entire length of the film is wound in an empty film cartridge in an unexposed state, so that the wound film cartridge side is the first film. It is preferable to use it as the container 12 and to use the empty cartridge side as the second film container 13. That is, it is preferable that the film-containing patrone used as the first film container 12 does not fix the inner end of the film to the winding core (spool), but allows the entire film to be transferred into the empty patrone during winding. Because.

Although not shown in the drawing, it goes without saying that the first film container 12 and the second film container 13 may be integrally formed as a cartridge.

Through hole 19 provided with the hoisting knob 16 on the upper surface of the camera body 11.
When the shaft portion 16a is directly connected to the spool 14 of the second film container 13 through the shaft portion 16a of the winding knob 16,
On the outer peripheral surface of the lower end portion of the spool 14, there are axially provided ribs 17 capable of engaging with the protrusions 14a, 14b provided on the inner peripheral surface of the spool 14 so as to engage with each other as shown in FIG. It does not slip in the direction of rotation. Also, the winding knob
A ratchet gear (a ratchet claw is not shown) 18 for preventing reverse winding is fixed to the shaft portion 16a of the 16 so as not to slip in the rotation direction.

The shaft portion 16a of the winding knob 16 is attached to the second film container 13
There are two ways to connect directly to. One is a method of incorporating the shaft portion 16a of the winding knob 16 into the spool 14 of the second film container 13 and then incorporating the container into the camera body 11.
The other one is that after the second film container 13 is incorporated into the camera body 11, the second film container is introduced from the outside of the camera body 11.
This is a method of connecting the shaft portion 16a of the hoisting knob 16 to the spool of 13. These two direct connection methods are the same in the form after the direct connection, and may be selected in consideration of the flow of the entire manufacturing process.

Reference numeral 20 denotes a light-shielding means for the camera body 11 and the hoisting knob 16. The light-shielding means 20 has various modes, one example of which is shown in FIGS. 1, 3, and 4. In the case of FIG. 1, while annular ribs 21 and 22 are raised around the through hole 19 provided on the upper surface of the camera body 11, concave grooves 23 and 24 are engaged with the annular ribs 21 and 22 in an ireco shape. It is provided on the lower surface of the upper knob 16 to form a maze of light.

In the case of FIG. 3, an elastic light shielding plate 26 having a through hole 25 that can be brought into close contact with the outer peripheral surface of the shaft portion 16a of the hoisting knob 16 is provided on the upper surface of the annular rib 21 raised around the through hole 19 of the camera body 11. It is pasted as shown in A of the same figure, and can be shielded from light as shown in B of the same figure.

In the case of FIG. 4, a light-shielding member (light-shielding cloth or light-shielding cloth) is attached to the inner peripheral surface of the annular rib 21 raised around the through hole 19 of the camera body 11 so as to be in close contact with the outer peripheral surface of the shaft portion 16a of the hoisting knob 16. A sponge) 27 is attached so that light can be shielded.

A mechanism required for photographing is incorporated in the camera body 11 as shown in FIG. Hereinafter, these mechanisms will be briefly described.

Reference numeral 28 is a sprocket meshed with the perforation P of the film 15 which is moved by rotating the winding knob 16 in the winding direction, 29 is a cam plate fixed to the shaft of the sprocket 28, and 30 is a shutter charge plate. The cam plate 29
A pin 29a is provided at a symmetrical position on the upper surface of the shutter charge plate 30, and the pin 29a extends halfway through the cam plate 29 (corresponding to the amount of rotation for winding the film 15 by one screen).
30a to engage the shutter charge plate 30 with a tension spring 31
Move to the right against. Due to this movement, the cutout portion 30b provided at the end of the shutter charge plate 30 is released into the release plate 32.
It is adapted to be locked to the protruding portion 32 '. This locking is performed before the half rotation of the cam plate 29 is completed, and from this point onward, the pin 29a extends beyond the protruding portion 30a of the shutter charge plate 30.
Get out of. Therefore, the shutter charge plate 30 receives a force in the returning direction due to the action of the tension spring 31. However, unless the release plate 32 is pushed to release the above-mentioned locking, the shutter charge plate 30 is kept in that state (shutter charge state). Become. At this time, a step portion (not shown) provided at a symmetrical position on the outer periphery of the cam plate 29 engages with a stopper (not shown) so that the hoisting knob 16 cannot be rotated further. In addition,
The stopper is designed to be disengaged from the step in the process when the shutter charge plate 30 is returned to the initial position when the release plate 32 is pushed.

Further, the shutter charge plate 30 is provided with a shutter striking piece 30c which is pivotally supported so as to be rotatable only in the clockwise direction. Therefore, the shutter charge plate 30 is moved while the shutter charge plate 30 is moving to the right. When the hitting piece 30c hits a pin on the head of the shutter wing 34 that shields the optical path of the taking lens 33, the hitting piece 30c rotates along the pin to get over it. Therefore, when the release plate 32 is pushed and the shutter charge plate 30 returns vigorously 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 wing 34 in the process. As a result, the shutter wings 34 rotate about the support shaft 35 to open the optical path of the taking lens 33, and then the return spring 36 acts to rapidly restore the original state.

37 is a counter window for displaying the number of film shots (or the remaining number). The counter window 37 has the sprocket 28
The scale of an index board (not shown) that rotates by one scale is exposed every time a gear (not shown) that is connected to and rotates. 38 is a simple direct view finder.

In the above embodiment, when the filming of a predetermined number of screens is completed, the film is entirely stored in the light-tight second film container 13, so that the film container is placed in a bright room in the camera body.
11 can be broken and taken out by an appropriate method.

〔The invention's effect〕

As described above, in the film-integrated camera of the present invention, an opening corresponding to the spool in the room is formed on the upper surface of the film winding room, and the spool from the film storage room to the film winding room is formed in the spool. Since the shaft of the winding knob that winds up the film is configured to be directly connectable, the installation space for the coupling mechanism between the spool of the film container and the winding knob can be largely omitted, and the film-integrated camera body This has the effect of reducing the vertical size. Further, in the film-integrated camera of the present invention, since the light-shielding means is formed between the upper surface of the hoisting chamber and the lower surface of the hoisting knob, the spool and the shaft of the hoisting knob can be directly connected. This has an excellent effect that the film winding chamber can be easily shielded from light.
