Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a film magazine, and more specifically, the present invention relates to a film magazine, and more particularly, a cutting means is disposed at one end of a film magazine that stores a film package in which a large number of sheet films are enclosed in a light-shielding bag, The present invention relates to a film magazine in which one end of the light-shielding bag is cut in a light-tight state by the cutting means to open the film package when the film package is stored in the film magazine.

2. Description of the Related Art A method of recording an object such as a human body on a film using X-rays is widely used for medical diagnosis and the like. In this case, an X-ray film is loaded into the X-ray imaging device in a light-shielded state, and the emulsion surface of the film is directly irradiated with X-rays to record an image of the subject.

Incidentally, recently, a radiographic image recording and reproducing system for obtaining a radiographic image of a subject using a storage phosphor (stimulable phosphor) has been developed, and is rapidly becoming popular, especially in the medical field as mentioned above. . Here, the storage phosphor refers to radiation (X
rays, alpha rays, beta rays, T rays, electron beams, ultraviolet rays, etc.), a part of this radiation energy is accumulated, and later by irradiation with excitation light such as visible light, the accumulated energy is A phosphor that exhibits stimulated luminescence.

The radiation image recording and reproducing system described above utilizes this stimulable phosphor, in which radiation image information of a human body, etc. is recorded once on a sheet having a layer made of the stimulable phosphor, and then the stimulable phosphor sheet is is scanned with excitation light such as a laser beam to generate stimulated luminescence light, the obtained stimulated luminescence light is read out photoelectrically to obtain an image signal, and based on this image signal, a recording material such as a photographic light-sensitive material, The image is output as a visible image on a CRT or the like.

Here, in order to record an image on a recording material, an image recording device, for example, an image output laser printer device is employed. This device stores photosensitive film, which is a recording material, through a magazine, etc., takes out the film one by one using a sheet-fed mechanism such as a suction cup, and then converts it into an electrical signal obtained from a stimulable phosphor sheet. Based on this, the film is irradiated with laser light to record a predetermined image. Next, this film on which the image has been recorded is conveyed into an automatic developing device, passes through a developing process, and is then accumulated at a predetermined location.

Incidentally, in the image output laser printer device, like the conventional X-ray imaging device described above, the film must not be irradiated with external light when the film is loaded into the device, but it is possible to improve the operability. Therefore, it is strongly desired to load the film in a bright room, and various techniques have been proposed to make this possible. As an example, a package in which a sheet film is enclosed in a light-shielding bag is stored in a magazine, both ends of the light-shielding bag are exposed from the magazine, and either end is cut off with a cutter or the like. be. In this case, the light-shielding bag is removed from the other end of the magazine, and the film remains in the film magazine.

However, when the light-shielding bag is removed from the magazine, light may enter through the opening of the light-shielding bag or the gap in the magazine.
There is a large area of the film that is exposed to external light, so considerable care must be taken in blocking light. Therefore, it may be possible to provide a cutting section for cutting off and opening one end of the light-shielding bag on the device side and a drive mechanism for this cutting section, and configuring the light-shielding bag to be opened within the light-tight device. In this case, the disadvantage is that the mechanism is extremely complex and large-scale.

In addition, as another example, a light-shielding bag has been devised in which one end is opened in advance and simply folded, but in this case, the light-shielding bag is accidentally opened before the package is stored in the magazine. There is a growing fear that it will not be able to be put to practical use.

The present invention has been made to overcome the above-mentioned disadvantages, and by providing a cutting means having a light-shielding effect in a film magazine that stores film packages, a light-tight state is created when loading the film packages. To provide an extremely simple and inexpensive film magazine in which the film packaging body can be opened at the same time.

In order to achieve the above object, the present invention provides a cutting means provided at one end of a film magazine that stores a film package in which a sheet film is enclosed in a light-shielding bag, and the light-shielding bag exposed from the film magazine.
