Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sheet film package and a device for loading the same, and more particularly, to a light-shielding member for holding a plurality of sheet films in a light-tight manner and the sheet. When a detection sheet having identification information is placed on a film, the film package is loaded into the apparatus, and when the detection sheet is sheeted, a sensor in the apparatus detects the identification information of the detection sheet. The present invention relates to a sheet film package capable of reliably determining whether or not a predetermined sheet film has been loaded and a device for loading the same.

BACKGROUND OF THE INVENTION Recently, a radiation image recording / reproducing system for obtaining a radiation transmission image of a subject using a stimulable phosphor (stimulable phosphor) has been developed and is being widely used. Here, the stimulable phosphor, when irradiated with radiation (X-rays, α-rays, β-rays, γ-rays, electron beams, ultraviolet rays, etc.), accumulates a part of the radiation energy, and subsequently excites visible light, It refers to a phosphor that emits stimulated light according to the energy stored by irradiating light.

The above-mentioned radiation image recording / reproducing system uses this stimulable phosphor, and records radiation image information of a human body or the like once on a sheet having a layer made of a stimulable phosphor, and then irradiates the stimulable phosphor sheet with a laser beam. Scan with excitation light to generate photostimulated light, and read the obtained photostimulated light photoelectrically to obtain an image signal.Based on this image signal, a recording material such as a photosensitive material, a CRT, etc. This is output as a visible image.

Here, when an image is recorded on a recording material, an image recording apparatus, for example, an image output laser printer is used. In this apparatus, a photographic photosensitive film, which is a recording material, is stored via a magazine or the like, and the films are taken out one by one by a sheet-feeding mechanism such as a suction disk. The film is irradiated with laser light to record a predetermined image. Then, the film on which the new image is recorded is conveyed into an automatic developing device, and after being subjected to a developing process, is stored in a predetermined place, and is used for medical diagnosis and the like as necessary.

In this case, in the image output laser printer device, when the photographic photosensitive film is loaded in the device, it must be handled so that the film is not irradiated with external light. This is because they are exposed. Accordingly, the film loading work is generally performed in a dark room, but the loading work efficiency naturally deteriorates. For this reason, in order to improve the workability, it is strongly desired to load a film in a normal light room. Technical ideas for making this possible include, for example, Japanese Utility Model Publication No. 61-20591. And the like.

By the way, the film to be used for the image recording operation has different exposure wavelengths such as an X-ray film, an infrared film or a visible light film, and is selected for various different sensitivities depending on the respective applications. I have.
As described above, since a considerably large number of types of films are generally used, there is a risk that an operator may erroneously load a package containing a film that is not applicable to the image recording apparatus. In this case, if a film which is not applicable is used in the image recording apparatus, a desired image cannot be recorded, and it is wasteful. On the other hand, if erroneous loading of the film is confirmed at the end of the development processing, there is a problem that the recorded image is lost until the erroneous loading is confirmed. As a result, it has been pointed out that it is difficult to perform an image recording operation efficiently, and that it is inconvenient both economically and temporally.

[Object of the Invention] The present invention has been made in order to overcome the above-mentioned inconvenience, and a plurality of sheet films and a detection sheet member having identification information stacked on the sheet films are provided in a light shielding member. Prepare the accommodated sheet film package, load the sheet film package into the apparatus, open the light blocking member, and first send out the detection sheet to the transport unit under the action of the sheet-feeding mechanism. The detecting means provided in the vicinity detects the identification information of the detecting sheet member, and determines whether the sheet film is a sheet film suitable for the apparatus or the image recording process thereof, and thereby applies. An object of the present invention is to provide a sheet film package and a device for loading the same, which can avoid the possibility of performing image recording on an external sheet film.

[Means for Achieving the Object] In order to achieve the above object, the present invention provides a light-shielding member having a bag shape and containing a plurality of sheet films, the sheet member being placed on the sheet film, A sheet member used only for detecting the type of the film, wherein the sheet member is made of the same material as the sheet film, is sent out by the same sheet-feeding mechanism as the sheet film, and has a type of the sheet film. And the type of the sheet film can be determined based on the identification information.

Further, in the invention, it is preferable that the identification information includes a display having different reflectances or transmittances of one or more lights drawn at a predetermined location on the sheet member.

Further, the present invention is characterized in that the identification information is recorded in advance on the sheet body by exposure.

Further, the present invention relates to an apparatus for loading a package having a bag-like shape and including a light shielding member having a plurality of laminated sheet films therein and a detection sheet placed on the sheet film. A sheet feeding mechanism for sending the stacked sheet films one by one to conveying means; and detecting the identification information of the sheet when the sheet faces the conveying means via the sheet feeding mechanism. Detecting means for determining whether or not the sheet film is a predetermined sheet film.The sheet-feeding mechanism determines that the sheet film is not a predetermined sheet film based on identification information of the sheet body. In this case, the sheet body is configured to be returned to the sheet film stacking position.

The identification mark 32 is drawn by exposing and recording on the detection sheet 30 in advance, and is actually composed of one or more white portions 34a and black portions 34b. In this case, the positions and numbers of the white portions 34a and the black portions 34b of the identification mark 32 are selected in accordance with the type of the film F, and the difference in the light reflectance between the white portions 34a and the black portions 34b is determined. Is detected by a reflection type optical sensor to be described later so that the type of the film F can be detected.

Further, as the identification mark 32, other identification information such as a barcode can be used instead of the combination of the white portion 34a and the black portion 34b described above.

Further, instead of the identification mark 32 as identification information,
Identification marks with different light transmittance can be used,
Alternatively, it is also possible to select the density of the entire detection sheet 30 and use it as the identification information. The identification mark 32
And the like may be separately formed, and this may be adhered to the detection sheet member 30 to be configured.

Next, an image recording device as a device for loading the package 10 will be described.

2 and 3, reference numeral 40 denotes an image recording device, and an automatic developing device 42 indicated by a two-dot chain line in the drawing is provided adjacent to the image recording device 40.

The image recording apparatus 40 includes a housing 44, and a film loading opening 46 is defined on one side surface of the housing 44, and a mounting table 48 is fitted into the opening 46 so as to be able to be pulled out. .

As shown in FIG. 3, a suction plate 50 constituting a single-wafer mechanism is disposed inside the housing 44. As shown by a broken line in the drawing, the suction disk 50 is displaced on a predetermined track, and a transport roller pair 52 is provided near the suction disk 50. One roller 54a constituting the roller pair 52 is configured to be able to advance and retreat with respect to the other roller 54b, and the one roller 54a and the other roller 54b are in sliding contact with each other via a coil spring (not shown). . A sprocket (not shown) is axially mounted on the other roller 54b, and one end of a chain 56 is stretched around the sprocket. The other end of the chain 56 is engaged with a sprocket 60 which is mounted on a rotary drive shaft (not shown) of a rotary drive source 58.

Therefore, a sensor (not shown) for detecting that the detection sheet 30 and the film F have entered between the pair of rollers 52 is provided near the pair of rollers 52, and the detection is performed in the vicinity of one of the rollers 54a. Means 62 are provided. The detecting means 62 comprises one or more optical sensors 64. When the leading end of the film F enters between the roller pair 52, the optical sensor 64
Each of the white portions 34a and the black portions 34b constituting the identification mark 32
The detection means 62 is positioned so as to be opposed to. In this case, the detecting means 62 detects whether the film F accommodated in the package 10 is a predetermined film by detecting the white portion 34a and the black portion 34b of the identification mark 32 based on the difference in reflectance. It is to detect.

Guide plates 66a and 66b for guiding the film F conveyed by the roller pair 52 to a scanning recording unit (not shown) are provided near the roller pair 52. In this case, the image recording device 40 is configured to record a desired image on the film F guided by the guide plates 66a and 66b and conveyed to a scanning recording unit (not shown), and then to convey the image to the automatic developing device 42. ing.

Next, the sheet film package 10 is attached to the image recording device 40.
The operation of loading the data into the cradle will be described below.

As shown in FIG. 2, the mounting table 48 constituting the image recording apparatus 40 is pulled out, the sheet film package 10 is loaded into the opening of the mounting table 48, and one end of the light shielding member 12 is closed.
16a is exposed outside from the mounting table 48. In this state, the mounting table 48 is inserted into the image recording device 40. Further, after the other end 16b of the light shielding member 12 is cut by a cutter means or the like, the one end 16a protruding to the outside is pulled in the direction of arrow B and extracted from the image recording device 40. As a result, the mounting table 48 is loaded with the plurality of films F and the detection sheet 30 mounted on the uppermost film F while being protected by the backing sheet 14.

Next, the sheet feeding mechanism is driven to bring the suction plate 50 into contact with the uppermost detection sheet 30 stacked in the mounting table 48, and a vacuum generator (not shown) is driven to drive the suction plate 50.
Thus, the detection sheet 30 is sucked. Then, the suction disk 50 is displaced on a track indicated by a broken line in FIG.
Hold it to 52.

At this time, the detection sheet 30 is connected to the roller pair 52 via a sensor (not shown) disposed close to the roller pair 52.
52 is detected, and the detection means 62
Is driven.

That is, as shown in FIG. 4, detection light is emitted from each optical sensor 64 of the detection means 62, and the white portion 34a and the black portion 34b of the identification mark 32 are detected based on the intensity of each reflected light. Therefore, it is detected whether the film F loaded in the image recording device 40 is of a predetermined type.
At this time, when it is confirmed that the film F is not applicable, for example, the display means provided in the image recording device 40 is driven, and the suction device 50 is operated under the action of the sheet-feeding mechanism. The detection sheet 30 held by suction is placed on the mounting table 48.
Is returned to. Therefore, the operator pulls out the mounting table 48, takes out the film F, and places a new package on the mounting table 48.
Just load 10.

On the other hand, when it is confirmed through the detection means 62 that the predetermined film F is loaded in the image recording device 40, the rotation driving source
The sprocket 60 is rotated by driving the 58, and the roller pair 52 is rotationally driven in the direction of the arrow via the chain 56 engaged with the sprocket 60. For this reason, the detection sheet body 30 sandwiched between the roller pair 52 is conveyed to a scanning recording unit (not shown) via the guide plates 66a and 66b, and furthermore, the automatic developing device
It is sent to the 42 side.

Next, the films F stacked on the mounting table 48 via the suction plate 50 are driven one by one under the driving action of the single-wafer mechanism,
The film F is held between the pair of rollers 52. Then, the film F is conveyed to a scanning recording unit (not shown) under the driving action of the rotary drive source 58 to record a desired image, and then the film F is conveyed to the automatic developing device 42 to perform a developing process.

After all the films F have been removed from the mounting table 48 and a predetermined image recording operation has been performed on the film F, the driving of the image recording apparatus 40 is stopped, and the mounting table 48 is pulled out.
A new unexposed film F may be loaded into the mounting table 48 as needed.

In this case, according to the present embodiment, it is possible to reliably and easily detect whether or not the predetermined film F is loaded in the image recording device 40.

That is, in the sheet film package 10, the detection sheet 30 is placed on the film F, and the identification mark 32 as identification information is provided on one edge of the detection sheet 10.
Is provided. On the other hand, the image recording apparatus 40 for loading the sheet film package 10 is provided with a detecting means 62 composed of a plurality of reflection-type optical sensors 64 in the vicinity of one roller 54a constituting the roller pair 52. Then, under the suction action of the suction disk 50 constituting the sheet-feeding mechanism, first, the detection sheet 30 is taken out from the mounting table 48, and the end of the detection sheet 30 enters the roller pair 52. At that time, a sensor (not shown) is energized, and the detection means 62 is driven. Here, as shown in FIG. 4, when the end of the detection sheet 30 is sandwiched between the pair of rollers 52, the identification mark 32 provided on the detection sheet 30 is moved to a position corresponding to the detection means 62. Is positioned. Accordingly, the detection light from each optical sensor 64 constituting the detection means 62 is accurately irradiated on the white portion 34a and the black portion 34b of the identification mark 32, and the type of the film F displayed on the identification mark 32 is changed. Can be read reliably.

In this way, the identification mark 32 is detected via the detection means 62 during the conveyance of the detection sheet 30, that is, when the leading end of the detection sheet 30 enters the roller pair 52. For this reason, for example, even when the sheet film package 10 is not accurately positioned with respect to the mounting table 48, the identification mark 32 of the detection sheet 30 is securely positioned with respect to the detection means 62, and the film F is used for image recording. It is possible to accurately detect whether or not the device is compatible with the device 40.
Moreover, since the detection sheet 30 is accommodated in the sheet film package 10, the identification mark 32
Is not hurt. That is, for example, if the identification mark 32 is provided on the sheet film package 10, the sheet film package 10 itself is damaged during transportation or the like, and the identification mark 32 is unnecessarily scratched. There is a risk of detection. When the identification mark 32 is attached to the sheet film package 10, the print pattern of the sheet film package 10 may have the same identification information as the identification mark 32, and the type of the film F is erroneously detected. .
Therefore, by using the detection sheet member 30, it is possible to reliably prevent the image recording operation from being performed on the film F that is not applicable via the image recording device 40, and it is possible to efficiently perform the image recording operation at once. Can be achieved.

Furthermore, in this embodiment, there is no fear that the film F is loaded on the mounting table 48 in a state where the film F is inverted. That is, when the sheet film package 10 is loaded on the mounting table 48 in an inverted state, the film F is first suction-held through the suction plate 50 under the driving action of the sheet-feeding mechanism. Then, when the film F enters the roller pair 52, the detecting means 62 is driven, and the detection light from each optical sensor 64 is irradiated onto the film F. However, in the film F, reflected light corresponding to the white portion 34a and the black portion 34b of the identification mark 32 is not detected. Therefore, it is confirmed that the film F is loaded on the mounting table 48 in an inverted state, and thereby, it is possible to prevent the inconvenience that the turned film F is conveyed to the scanning recording unit (not shown).

In the above-described embodiment, an example has been described in which the identification mark 32 has a display with a different reflectance. However, a display with a different transmittance may be used. In this case, a well-known transmission sensor may be used as a detecting unit. Also, instead of providing the identification mark 32 on the detection sheet member 30, the transmittance or reflectance of the entire detection sheet member 30 is made different for each type of the film F. The type of the film F may be detected.

[Effects of the Invention] As described above, according to the present invention, a plurality of sheet films are light-tightly accommodated in a light shielding member, and a detection sheet having identification information is placed on the uppermost sheet film. On the other hand, a device for loading the sheet film is provided with a detecting means for detecting the identification information. For this reason, after loading the sheet film package into the device,
First, when the sheet for detection is taken out and faces the transport system, the identification information of the sheet for detection is detected by the detecting means to detect whether or not a sheet film suitable for image recording is loaded in the apparatus. I can do it. in this way,
In order to detect the identification information via the detection means when positioning the detection sheet body in the conveyance system during the conveyance,
The identification information can be read accurately and easily.

As described above, the present invention has been described with reference to the preferred embodiments. However, the present invention is not limited to these embodiments, and various improvements and design changes can be made without departing from the gist of the present invention. Of course.
