Abstract

PROBLEM TO BE SOLVED: To set the interval of two cartridges on the supply side and read side of a double cartridge system to be suitable for the interval of a cartridge chamber set at a camera before loading it to the camera. SOLUTION: The end part of a flexible member T1 having a specified length is stuck to the outer peripheral surfaces of respective film entrances of a cartridge PS on the supply side and that PT on a take-up side, and the flexible member T1 is extended at the time of loading it to the camera. Thus, the distance (axle-to-axle distance) D of the cartridge PS is suited to the distance of the cartridge chamber set to the camera, and the flexible member T1 is peeled and removed from the cartridge after being loaded.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a patrone for a camera used in a so-called double patrone system in which an unexposed film of one patrone is exposed and wound around the other patrone, and a camera loaded with the patrone and used.

[0002]

2. Description of the Related Art According to the double patrone system, an unexposed film unwound from a patrone on a supply side is successively wound on a patrone on a take-up side after exposure and kept in a light-shielding state. The camera can be immediately taken out without going through the returning process.

Therefore, a camera of the type in which a film is loaded by the double patrone system does not require a rewinding device and its operation process, so that the mechanism is simplified, and damage to the film due to transport is reduced.

[0004]

However, in a double patrone camera, the two patrones on the supply side and the take-up side are set at an interval suitable for the interval of the patrone chamber set in the camera before loading. Therefore, the user has taken a method of visually judging the drawing-out length of the film from the patrone on the supply side and setting the patrone interval depending on the feeling.

As a solution to such a problem in handling, there has been proposed a film cartridge in which two patrones are fixed and integrated as in Kodapacks 126 and 110, but has a configuration in which a pressure plate is omitted. Therefore, there is a drawback in terms of the flatness of the film, and there is a disadvantage that the volume is large and thus it is not suitable for carrying.

The present invention has solved and improved the above points,
It is an object of the present invention to provide a camera patrone that can be set compactly and carried in a compact manner without depending on the distance between two patrones without depending on the feeling, and to provide a camera using such a camera patrone. It was done.

[0007]

SUMMARY OF THE INVENTION The object of the present invention is to provide a camera cartridge in which a supply-side patrone for storing an unexposed film and a take-up patrone for storing an exposed film are integrally loaded into a camera body. Wherein the distance between the patrone and the take-up side patrone is regulated via a flexible member, and a patrone for the camera storing the unexposed film and an exposure. A camera cartridge in which a take-up patrone for accommodating a finished film is integrally loaded into a camera body, wherein a gap between the supply-side patrone and the take-up patrone is regulated via a flexible member. This is achieved by a camera (the invention according to claim 5) using a camera cartridge.

[0008]

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention according to claims 1 and 6 will be described with reference to FIGS.

A camera shown as an embodiment is shown in FIG.
As shown in FIG. 1 (a), a photographing lens L, a finder F, a strobe S and a release button R are further provided on the front surface, and when loading a film, the camera back cover 2 is opened as shown in FIG. 1 (b). As shown in FIG. 1 (c), the patrone PS on the supply side set at the interval D between the patrone chambers 1a and 1b and the leading end of the film are locked to the patrone chambers 1a and 1b for supplying and winding the camera body 1. By inserting the patrones PT on the winding side to be wound, and then closing the back cover 2, the film f stretched between the patrones is brought into contact with the camera body by the film crimping plate 2a of the back cover 2. 1 is pressed or sandwiched on the rail surface 1c so as to be set on the imaging surface of the photographic lens L.

The exposed film is sequentially wound around the cartridge PT and is taken out while maintaining the light-tight state. Therefore, no rewinding device is provided.

The above-mentioned patrone PS on the supply side and the patrone PT on the take-up side are each provided with a tape-like flexible member T1 having a predetermined length on the outer peripheral surface of the patrone at the entrance of the film, respectively. The patrone can be carried in a compact state by reducing the volume occupied by the patrone by folding the flexible member T1 as shown in FIG. Figure 2
As shown in (b), the space (the distance between the axes) D between the patrone PS and the patrone PT is adjusted to the distance between the patrone chambers set in the camera main body 1 by simply extending the flexible member T1, and the cartridge is easily loaded. It has become.

As the above-mentioned flexible member T1, a thin sheet made of, for example, synthetic resin or paper having a very small elasticity is used, and the thin sheet is removed from the surface of the flexible member T1 after being loaded into a camera. Attention, a sentence or a graphic is displayed.

Further, the above-mentioned tape-shaped flexible member T1
Alternatively, a frame-shaped flexible member T2 as shown in FIG. 3 can be used.

As the material of the flexible member T2, the same material as that of the flexible member T1 is used, but the length A and the width B of the back cover 2 which can be inserted through the film crimping plate 2a are used. Therefore, the frame-shaped flexible member T2 does not need to be removed even after the patrone is loaded into the camera, and the handling is simplified.

The present invention can be applied to a camera having a film rewinding mechanism. In this case, a take-up spool shaft may be used in place of the above-mentioned patrone PT on the take-up side. The flexible member T1 described above
Alternatively, both ends of T2 are attached to the patrone PS on the supply side and the flange portion of the take-up spool shaft, for example.

[0016]

According to the first aspect of the present invention, the loading of the double patrone type patrone into the camera which is easy to carry can be carried out with proper and easy operation. In addition to the use of the above-mentioned patrone, the take-up and the use of the spool shaft are made possible. Further, according to the third and fourth aspects, the safety of the loading operation is ensured, and the patrone for the camera with improved simplicity is provided. Items 5 and 6 make it easy to load the patrone, and the film crimping plate 2a has a frame-shaped flexible member T.
2, the film is kept in good flatness, the film is photographed in good focus, and a simple camera with no rewinding mechanism is realized. .
