2. Description of the Related Art Roll film called 35mm film
J135 (JIS K7519) is a patrone (J
It is housed in the ISK7528) in a light-tight state and loaded into an appropriate camera for use.

One of the cameras using such a film
One type is to repeat the exposure and film winding operation to take pictures one after another, and after the shooting is finished, operate the rewinding device to rewind the exposed film wound on the take-up shaft into the cartridge. , Open the case back and take out the cartridge.

In other types of cameras, after the film is loaded, the film is wound up on the take-up shaft prior to the shooting operation, and thereafter, the film is rewound one frame at a time in the patrone for shooting. After the shooting is finished, the case back is opened and the patrone is taken out. In this way, in any of the above types of cameras,
Since the mm film is used, it is necessary for the user to reciprocally feed the film in the camera. Therefore, the film rewinding device is indispensable.

[0005]

[Problems to be Solved by the Invention] On the other hand, in recent years, a simple camera which does not require a rewinding device as described above and which is inexpensive has been proposed and put into practical use.
It uses a cartridge containing 0 type film.

A camera using a 110 type cartridge has a front outer frame made of resin, to which a shutter button is attached, and an opening for a lens, an opening for a finder, and an opening for a film winding member are formed. A shutter frame, a shutter charge mechanism, and the like are attached, and a main body frame made of resin having a cartridge housing portion and an eyepiece opening forming a finder is provided. Both sides of the (frame to be formed) are joined by thin screws, and the back side opening of the main body frame is used to load the cartridge into the cartridge storing section, and one end is screwed to the main body frame by a spring plate. The cartridge is configured to be pressed against the body frame.

However, in the above structure, the screw connecting portion between the main body frame and the outer frame on the front side has to be made thick as such, so that there are disadvantages that the material is wasted and it takes time to integrate. is there. Also, since the end of the spring plate on the side opposite to the screw fixing side is inserted into a narrow slit provided in the main body frame and then the screw is fixed, this fixing work also takes time and unless a thin screw is used. It is difficult to handle because it does not happen. A further object of the present invention is to provide a novel film-integrated camera that uses a normal cartridge type film, rather than the cartridge type, in which the above problems are prevented as much as possible.

The hoisting fork 53 projects into the cartridge chamber 11 and engages with the spool 2 of the cartridge 1.

Reference numeral 54 denotes a 16-tooth sprocket gear installed so that the tooth tips are exposed on the rail surface 14, and 55 denotes a cam plate having a pair of step portions 55a and a drive pin 55b at symmetrical positions on the outer periphery. It is mounted on a shaft S-1 so as to rotate integrally with the sprocket gear 54.

That is, when the winding knob 51 is rotated counterclockwise in FIG. 2, the spool 2 is rotated to wind the film F into the cartridge 1 while the film F meshes with the perforation P. Gear 54
The cam plate 55 is driven and rotated counterclockwise via the.

Numeral 61 is slid in the left-right direction on the upper surface of the first unit with two mounting holes 62 formed in the first unit 10 as guides through two elongated holes 100 drilled in itself. It is a shutter charge plate that is constantly biased to the right by a tension spring 63.

As will be described later, the position of the shutter charge plate after the photographing operation is displaced to the right of the drawing, but the movement to the illustrated position (shutter charge position) is performed as follows.

That is, as the winding knob 51 rotates, the cam plate 55 rotates counterclockwise together with the sprocket gear 54 via the film.

Then, during its rotation, the pin 55b on the cam plate engages with the projecting portion 61a of the shutter charge plate, and the charge plate is moved to the left in the figure against the tension spring 63. Before the half rotation of the plate, that is, the rotation amount for winding the film F by one screen, is reached, the protrusion of the laris plate 56 is reached.

Engage to prevent the winding operation of the winding knob 51.

FIG. 2 shows a state in which the film F is wound up by one screen and the shutter charging is completed at the same time and the winding knob 51 is stopped. In this state, the release button 57 is pressed. When the release plate 56 is pushed down by
Since the shutter charge plate 61 is unlocked, it moves rapidly to the right due to the action of the tension spring 63, and in the process, the falling portion 61c causes the pin 67a of the reversing member 67 provided at the tip of the shutter blade 66 to move. The shutter blade 66 is rotated clockwise to open the optical path of the taking lens 40 for exposure.

Since the shutter blade 66 is regulated by the tension spring 66a at a position where it blocks the optical path, the taking lens 4
Immediately after fully opening the optical path of 0, the pin 67a is
When it is disengaged from the engagement with 61c, it automatically returns to the initial position and performs a predetermined exposure.

Further, when the shutter charge plate 61 is moved to the right side, a part of it is positioned above the projecting portion 56 'of the release plate 56, and is moved upward by a biasing means (spring) not shown. Prevents the release plate from moving to the initial position.

That is, unless film winding is performed,
The shutter button 57 is maintained in a hole 28 provided in the front outer frame 20 so as not to be operated. The reference numeral 200 is the winding knob 51.
It is a reverse rotation prevention claw that blocks the clockwise rotation of.

Enters into the groove 32 continuously formed so as to face the peripheral portion of the third unit 30 and constitutes a light shielding wall, so that the film F is kept in a light shielding state.

The external dimensions of the film-integrated camera having the above-described structure are compact with a width of 120 mm, a height of 55 mm, and a depth of 35 mm.

A flat and smooth pressing portion 33 having a size for covering the screen frame 13 is integrally formed on the inner surface of the third unit 30.

The pressing portion 33 has a function of maintaining the flatness of the film F positioned between the rail surface 15 and the rail surface 14 provided inside the rail surface 15, and also serves to reinforce the third unit. There is.

Next, the operation will be described. In the film-integrated camera configured as described above, the user only has to wind the film equivalent to two screens and perform aerial shooting (pressing the shutter button 57) to move the film F to the position of the screen frame 13. The unexposed part can be pulled out, and the photographable state is obtained. This is indicated by the index board 71.

Thereafter, the photographing lens is pointed at the subject and the shutter button 57 is pressed to take a photograph. Next, by winding the winding knob 51 counterclockwise until the film is stopped, one screen of the film F is fed, the shutter is charged, and the film counter is operated, so that the next frame can be photographed. .

In this way, as the film counter index is changed by 1 in accordance with the shooting / winding operation,
For example, when 24 images have been taken, it is displayed that the predetermined number of screens have all been taken.

The above is the user's action. However, if the user or the processor continues to take several aerial shots thereafter, all the effective screens are stored in the patrone 1 and the film F
1 reaches the position shown by the alternate long and short dash line in FIG. 1 and is stopped. This state is easily confirmed by the release lock caused by the sprocket gear 54 being unable to rotate.

The processor can easily separate and destroy the third unit 30 by disengaging the third unit 30 from the engagement with the first unit 10 in a bright room with a driver or the like, and the film in the light-shielded state housed in the cartridge 1. F can be taken out and processed.
