[Detailed Description of the Invention] The present invention relates to a storage device for sheet-like photosensitive material (hereinafter referred to as 'filmyo'). Specifically, when a film storage magazine is attached to a film feeding device, the storage magazine is rotated by the motor of the feeding device. The present invention relates to a film storage device that applies force and can automatically detect when the amount of film fed into a storage machine reaches a certain value.

2. Description of the Related Art When taking an X-ray photograph in a hospital or the like, the place where the photograph is taken is often different from the place where an automatic developing machine for developing the photograph is installed.

Therefore, it is necessary to transport the photographed X-ray film (hereinafter simply referred to as 1 film) from the photographing location to the automatic developing machine installation location. Hereinafter, it will be simply referred to as 1-cassette-yo), in order to increase the efficiency of its use.
Also, from the viewpoint of reducing the weight during transportation, it is not a good idea to transport this to the location where the automatic developing machine is installed.

As a means to solve this problem, a portable film storage magazine has been used that takes out the film from the cassette, stores it temporarily, and then transports it when a certain amount of film has been accumulated. .

This type of magazine is equipped with a flexible belt wrapped around two drums and a pair of film transport rollers installed at corresponding positions, and both are driven in synchronization to transport the film into the flexible belt. A structure is known in which the film is wound up and stored in a flexible belt, and the wound film is discharged by unwinding the flexible belt.

In the magazine, the amount of film stored is indicated by the number of film sheets stored, for example, by counting the number of film sheets stored, which is detected by a limit switch provided near a pair of film transport rollers.

However, since film usually comes in a variety of sizes, when the amount of film stored is expressed by the number of films stored, it becomes difficult to determine the allowable number of films stored in the magazine. In the end, the capacity of the magazine had to be set to the maximum number of sheets of film that could be accommodated, which resulted in the drawback that the capacity of the magazine could not be used effectively.

Furthermore, there is a risk that the operator may feed more film than the allowable amount without looking at the display of the number of stored films, and in this case, the film exceeding the allowable amount will not be stored in the specified position in the magazine. There were drawbacks such as damage and exposure to light.

Furthermore, if the power source is inside the magazine, the volume and weight will be large, making it inconvenient to transport.Moreover, magazines with electrical contacts outside the magazine have the disadvantage of frequent failures and reduced reliability. There is.

The purpose of this invention is to eliminate these conventional drawbacks, eliminate the internal power source, effectively utilize the storage space of the magazine, and reduce the weight. It is an object of the present invention to provide a highly reliable sheet-like photosensitive material storage device that prevents further feeding of film and is not provided with an electrical contact point with the outside.
