Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a sheet film loading method and a package thereof, and more specifically, the present invention relates to a sheet film loading method and a package thereof, and more particularly, when a package that stores a plurality of sheet films in a light-shielded manner is installed in an image recording device, the present invention relates to a sheet film loading method and a package thereof. A flexible light-shielding cover member constituting the body and having one end protruding outside is inserted into a passage provided in the device and peeled off from the package.Therefore, the sheet film can be placed in a bright room with an extremely simple structure. The present invention relates to a sheet film loading method that can be easily loaded and a package thereof.

Generally, in medical diagnosis, X-ray film, which is an image of a subject such as a human body using X-rays, is widely used. Conventionally, when taking such X-ray film,
An X-ray film is loaded into a radiation imaging device in a light-shielded state, and the emulsion surface of this film is directly irradiated with xH to record an image of the subject.

By the way, recently, a radiographic image recording and reproducing system has been developed that uses a storage phosphor (stimulable phosphor) to obtain a radiographic image of a subject, and this system is widely used against the medical field as mentioned above. . Here, the storage phosphor refers to radiation (X
When irradiated with rays, alpha rays, beta rays, rklA, electron beams, ultraviolet rays, etc.), part of this radiation energy is accumulated, and later by irradiation with excitation light such as visible light, a brightness corresponding to the accumulated energy is generated. A phosphor that exhibits exhaustion.

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 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, when recording a visible image on a recording material, an image recording device, for example, an image output laser printer device is employed. This device stores photographic film, which is a recording material, through a magazine, etc., takes out the film one by one using a sheet dispensing mechanism such as a suction cup, and then collects electrical signals obtained from a stimulable phosphor sheet. A predetermined image is recorded by irradiating the film with laser light based on the following. This film is then 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, when loading the film into the device, external light must not be irradiated on the film. It has become highly desirable to load the film in a normal bright room, and various methods of loading the film in a bright room have been considered. Utsukai Showa 56-5
No. 141 discloses an example of this bright room loading method.

That is, FIG. 1a shows a cross-sectional view of a film package 2 to be supplied to an X-ray imaging device, etc., and this film package 2 includes a light-shielding container 6, which is a housing having an opening 4. A plurality of unexposed films 10 are stored in the light-shielding container 6 while being protected by a cardboard 8.

Further, a flexible light-shielding member 12 is adhered to the opening 4 in a light-tight manner to protect the unexposed film 10 from external light. In this case, one end of the flexible light shielding member 12 is curved vertically upward, and a locking hole 12 is provided at the edge of the one end.
A is drilled.

The film package 2 thus constructed is stored in a magazine 14 shown in FIG. 1 and positioned by a storage section 16. Here, the magazine 14 includes a shutter member 1.
8 is provided, and the hole 12 of the flexible light shielding member 12 is inserted into the locking protrusion 20 implanted at the end of the shutter member 18.
After the magazine 14 is attached, the magazine 14 is loaded into an X-ray imaging device (not shown) or the like. Next, the other end of the shutter member 18 is pulled out from the magazine 14 by hand or the like.

As a result, the flexible light-shielding member 12 is peeled off from the light-shielding container 6 by the locking protrusion 20 that engages with the hole 12a, and the opening 4 is opened in the X-ray imaging apparatus or the like. and,
The unexposed film 10 is sucked by a vacuum suction device 22 and transported to a predetermined photographing position.

However, in the prior art described above, a dedicated magazine must be used to store the film package.

This dedicated magazine must be manufactured strongly so that it can withstand repeated attachment and detachment, and therefore the dedicated magazine itself has a considerable weight. Therefore, a drawback arises in that it is troublesome for the operator to attach and detach the dedicated magazine. Moreover, since the dedicated magazine is provided with a shutter mechanism and the like, it becomes quite expensive. In particular, when using various films of different sizes, it is necessary to prepare a dedicated magazine for each size of film, which significantly increases manufacturing costs and is inconvenient in that it is not economically acceptable in practice. is pointed out.

The present invention has been made to overcome the above-mentioned disadvantages, and includes a tray base for storing a plurality of films in a stacked manner, and a flexible tray base that is peelably adhered to the tray base and has one end thereof protruding outside. When a package including a light-shielding cover member is attached to an image recording device, the tray stand and the cover member are inserted into respective openings provided in the device, and the cover member is peeled off from the tray stand. Accordingly, it is an object of the present invention to provide a method for loading a sheet film and a package for the same, which allows loading of a film in a bright room with a simple structure and with great ease.

In order to achieve the above object, the present invention is provided in correspondence with a sheet dispensing mechanism of an image recording apparatus, and one end side communicates with a loading opening into which a tray stand containing stacked sheet films is inserted. The tip of the flexible cover member for shielding the tray stand from light is exposed to the passageway, and then the flexible cover member is introduced into the passageway by moving the tray stand toward the sheet dispensing mechanism. and peeling it off from the tray base, thereby defining a sheet dispensing opening in the tray base.

Furthermore, it is comprised of a tray stand for storing a plurality of sheet films in a stacked manner, and a peelable flexible cover member that blocks light from the sheet films stored in the tray stand and closes the opening of the tray stand; The distal end of the cover member is formed to protrude outward from the distal end of the tray stand, and the distal end of the cover member enters a cover member peeling passage defined in the image recording device, and the tray stand is loaded and moved. The present invention is characterized in that the cover member is configured to be peeled off from the tray base upon operation.

Next, preferred embodiments of the sheet film loading method according to the present invention in relation to a package for carrying out the method will be described in detail with reference to the accompanying drawings.

In FIG. 2, reference numeral 30 indicates a sheet film package according to the present invention. In this case, the package 30 includes a tray base 32 made of a resin material or cardboard having a predetermined hardness, and a cover member 34 made of a flexible material. This tray stand 32 has a height Hl in order to store a predetermined number of films A, and has a film ejection opening 38 having a predetermined width near the tip of the top surface 36.
is formed. Then, the cover member 34 is attached to the upper surface #3 with an adhesive or the like so as to close this opening 3 days.
The cover member 3 is releasably fixed to the cover member 3
One end of the tray 4 is formed to protrude outward from the tip of the tray stand 32.

On the other hand, an image recording device 40, such as an image output laser printer device, to which the package 30 is attached is constructed as shown in FIGS. 3 and 4. That is, the image recording device 4
0 has a width H2 in the height direction of the package 30.
A first opening 44 having a rectangular cross section and having a longitudinal width the same as the width of the package 30 is defined, and a tray stand 32 is provided at one end of the first opening 44. It communicates with a second opening 46 having a height H' (see FIG. 4). In this case, the first opening 44 extends inward from the front surface part 42 by a predetermined distance, and furthermore, the bottom part defining the first opening 44 and the second opening 46 is integrally formed. They are formed at the same height position and constitute a base surface 47.

A passage 48 having a cross-sectional shape substantially the same as that of the cover member 34 that is curved upward from the horizontal direction and opened to the front surface portion 42 is defined at the boundary between the openings 44 and 46. . In this case, a locking surface 50 is provided at the terminal end of the base surface 47 and is oriented vertically upward.
0 and the front portion 42 is selected in accordance with the length of the package 30. Note that a single sheet mechanism (not shown) including a suction cup 54 is provided in the chamber 52 within the image recording device 40 .

Note that it is desirable that a raised material or the like be provided on the wall surfaces around the first and second openings 44 and 46 in order to improve light shielding properties when the package 30 is loaded.

The package and image recording device according to the present invention are basically constructed as described above, and the functions and effects thereof will be explained next.

First, the protruding end of the cover member 34 is inserted into the opening 44 of the image recording device 40, and the cover member 34 is slightly pressed against the upper surface defining the opening 44. When inserted in the direction of the arrow, the distal end of the cover member 34 faces the passage 48 . Here, the passage 48
is inclined upward at a predetermined angle with respect to the horizontal direction, and on the other hand,
If the cover member 34 is made of a slightly hard and flexible material, the cover member 34 can curve into the passage 48.

Next, when the packaging body 30 is displaced in the direction of the arrow shown in FIG. The cover member 34 is attached to this tray stand 32.
It is peeled off from the upper surface part 36 of.

In this case, the cover member 3 led out from the passage 4
If the operator grasps the end of the cover member 4 and pulls it in the direction opposite to the direction in which the package 30 enters, the peeling operation of the cover member 34 can be made even more smoothly. During this time, since the opening 44 has the same width as the height H2 of the package 30 and extends a predetermined length inside the image recording device 40, the cover member 34 is When the tray is peeled off from the tray 32, light from the outside does not enter into the opening 38 of the tray 32.

In this manner, when the package 30 is advanced in the direction of the arrow, its tip comes into contact with the locking surface 50, and the installation work of the package 30 is completed. At this time, since the locking surface 50 and the front part 42 are separated by the distance H1, the opening 38 of the tray stand 32 can be suitably faced to the chamber 52. Therefore, by driving a single-fed mechanism including a suction cup 54, the films A stacked and stored in this tray stand 32 can be sequentially conveyed to a recording section (not shown), where they can be used for recording radiographic image information. becomes.

Next, when all the films A stored in the tray stand 32 are taken out, the package 30 is transferred to the image recording device 4.
If it is displaced in the direction away from 0, the tray stand 32
and cover member 34 can be removed integrally from this image recording device 40.

Furthermore, the used package 30 can be disposed of, especially if the tray stand 32 is made of an inexpensive resin material, cardboard, or the like. Moreover, when using various films of different sizes, even if packaging bodies corresponding to the films of each size are prepared, the cost will not increase to any significant extent. In addition, when using various films in this way, record the film type, film size, film loft number, etc. on each package in advance with a bar code, magnetic tape, etc., and record them on the image recording device. It is convenient for image recording if the information is read and displayed by a reading means provided in the image recording device when the package is attached.

Incidentally, in this embodiment, the cover member is configured to be led out from the front surface of the image recording apparatus, but it is also possible to house the cover member inside the image recording apparatus. The configuration will be described below as a second embodiment. Components that are the same as those shown in FIG. 4 are designated with a suffix a, and their explanations will be omitted.

That is, as shown in FIG. 5, a passage 48a formed in the image recording device 40a is bent from the boundary between the openings 44a and 46a, extends upward, and communicates with the interior of the chamber 52a. A partition plate 56 is disposed within this chamber 52a so as to be oriented in the vertical direction.

Therefore, when mounting the package 30 on the image recording device 40a, it is carried out in the same manner as the image recording device 40 described above, but in this second embodiment, the cover member 34 is not led out to the outside. Rather, it is accommodated within the space defined by the partition plate 56.

At this time, since the cover member 34 is guided by the partition plate 56, it does not interfere with the single-fed operation of the suction cup 54a. Note that the used packaging body 30 is transferred to the image recording device 40.
When taking out the tray from the tray a, the tray stand 32 and the cover member 34 may be pulled out integrally in the same manner as in the first embodiment.

In the embodiment described above, the opening 3 is formed in a part of the upper surface 36 of the tray stand 32, but the entire upper surface 36 of the tray stand 32 is left as an opening, and the cover member is peeled off. The film may be fed one by one by opening a portion of the opening.

As described above, according to the present invention, a cover member is removably adhered to a tray stand for storing a plurality of films by closing the film ejection opening, and one end side of the cover member is attached to the tray stand. It is configured to protrude further to the outside. Therefore, when this package is attached to an image recording device, by inserting the cover member and the tray stand into predetermined openings of the image recording device, the cover member is automatically peeled off from the tray stand. It is possible to do so. Therefore, it is possible to load the film in a bright room with an extremely simple structure. Furthermore,
Since the package is directly mounted in the device, there is no need to use a dedicated magazine as in the past, and the device is manufactured at low cost and lightweight, making it possible to more easily load the film.

Although the present invention has been described above with reference to preferred embodiments, the present invention is not limited to these embodiments.
For example, if the end of the cover member is slightly bent or curved vertically upward, the cover member can be more easily introduced into the passage, etc. Various improvements and design changes may be made without departing from the gist of the present invention. Of course, this is possible.
