Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a sheet film package and a loading device therefor. A detection sheet body having identification information is placed on a sheet film, and when the film packaging body is loaded into a device and the detection sheet body is fed one by one, a sensor in the device identifies the detection sheet body. The present invention relates to a sheet film package and its loading device that makes it possible to reliably determine whether or not a predetermined sheet film is loaded by detecting information.

[Background of the Invention] Recently, a radiation image recording and reproducing system for obtaining a radiographic image of a subject using a stimulable phosphor (stimulable phosphor) has been developed and is becoming widespread. Here, a stimulable phosphor refers to a stimulable phosphor that, when irradiated with radiation (X-rays, α-rays, β-rays, T-rays, electron beams, ultraviolet rays, etc.), accumulates a portion of this radiation energy and later excites it with visible light, etc. A phosphor that exhibits stimulated luminescence according to the energy accumulated by irradiation with light.

The radiation image recording and reproducing system described above utilizes this stimulable phosphor, and radiation image information of the human body, etc. is recorded on a sheet having a layer of stimulable phosphor, and then this stimulable phosphor sheet is exposed to a laser beam. The stimulated luminescence light is generated by scanning with an excitation light of This is to output it as a visible image.

Here, when recording an image on a recording material, an image recording device, for example, an image output laser printer device is used. This device stores photographic 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 uses electrical signals obtained from a stimulable phosphor sheet to The device is configured to irradiate the film with laser light and record a predetermined image. Therefore, the film on which the new image has been recorded is conveyed into an automatic developing device, undergoes a developing process, and is then stored at a predetermined location, where it is used for medical diagnosis, etc., as necessary.

In this case, in the image output laser printer device, when loading the photosensitive film into the device, the film must be handled so as not to be exposed to external light.

This is because you will be exposed to light. Therefore, when fishing on a boat, loading the film is carried out in a darkroom, but the efficiency of the loading operation naturally deteriorates. Therefore, in order to improve the workability,
There was a strong desire to load film in a normal bright room, and technical ideas to make this possible, for example,
It is disclosed in Utility Model Publication No. 61-20591.

By the way, films used for image recording work have different exposure wavelengths, such as X-ray film, infrared film, or visible light film, depending on their respective uses, and are also selected to have various different sensitivities. There is. As described above, since a considerable variety of films are commonly used, there is a risk that an operator may mistakenly load a package containing an unsuitable film into an image recording apparatus. In this case, if a film other than the above-mentioned film is used in the image recording apparatus, the desired image cannot be recorded, and it is also wasteful. On the other hand, if it is confirmed that the film has been erroneously loaded after the development process is completed, a problem arises in that images recorded before the erroneous loading is confirmed are lost. It has been pointed out that as a result, it becomes difficult to perform image recording work efficiently, resulting in economic and time inconveniences.

It is an object of the present invention to provide a sheet film package and a loading device for the same, which makes it possible to avoid the risk of recording an image on an unsuitable sheet film.

[Means for Achieving the Object] In order to achieve the above-mentioned object, the present invention provides a light-shielding member having a bag shape and having a plurality of sheet films therein, and a detection sheet placed on the sheet film. including the body,
The sheet body has different identification information corresponding to the type of sheet film, and the type of the sheet film can be determined based on the identification information.

Further, the present invention is characterized in that the identification information consists of one or more indications having substantially different reflectances or transmittances of light drawn at predetermined locations on the detection sheet.

Further, the present invention is characterized in that the detection sheet is made of substantially the same material as the sheet film, and the identification information is previously exposed and recorded on the detection sheet.

Furthermore, the present invention includes a sheet-fed mechanism that feeds the sheet film one by one to a conveyance means, and detects identification information of the detection sheet when the detection sheet faces the conveyance means via the sheet-fed mechanism. and detecting means for determining whether or not the sheet film is a predetermined sheet film.

[Embodiments] Next, preferred embodiments of the film package and its loading device according to the present invention will be described in detail with reference to the accompanying drawings.

In FIG. 1, reference numeral 10 indicates a sheet film package according to the present embodiment, and this package IO is a light shielding member 1.
2 and a cover sheet 14 for protecting the film F disposed inside the light shielding member 12. The light shielding member 12
is made of a flexible material, has a substantially bag-like shape, and both ends 16a116b are optically sealed.

On the other hand, the glitter paper 14 is formed by bending, for example, cardboard or the like. That is, the glitter paper 14 has a lower surface portion 20, and a side surface portion 22 is formed on one end side of the lower surface portion 20, oriented vertically upward and bent at a substantially right angle. An upper surface portion 2 is provided at the upper end of the side surface portion 22 and extends substantially parallel to the lower surface portion 20 and is shorter than the lower surface portion 20.
4, and a presser portion 26 that bends downward toward the lower surface portion 20 is formed on one side of the upper surface portion 24. This holding portion 26 is present on one end 16a side of the light shielding member 12. The upper surface part 24 and the presser part 26
is swingable about the joint 28 between the upper surface 24 and the side surface 22 as a fulcrum.

A plurality of films F are stacked and stored between the lower surface part 20 and the upper surface part 24 of the cover sheet 14 configured in this way, and a detection sheet body 30 is mounted on the uppermost film F. be done. The detection sheet 30 is made of substantially the same material as the film F, and an identification mark 32, for example, is formed on one edge of the detection sheet 30 as identification information. The identification mark 32 is drawn on the detection sheet 30 by exposure recording in advance, and actually consists of one or more white portions 34a and one or more black portions 34b. In this case, the white portion 3 of the identification mark 32 corresponds to the type of film F.
4a and the black portion 34b, and detect the difference in light reflectance between the white portion 34a and the black portion 34b using a reflective optical sensor, which will be described later, to detect the type of film F. It is what makes it possible.

Further, as the identification mark 32, the white portion 34a described above is used.
Of course, other identification information such as a bar code can be used instead of the combination of the black part 34b and the black part 34b.

Furthermore, instead of the identification mark 32 as identification information,
Identification marks with different light transmittances 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. Note that the identification mark 32 and the like may be formed individually and attached to the detection sheet body 30.

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

In FIGS. 2 and 3, reference numeral 40 indicates an image recording device, and an automatic developing device 42 shown by a chain double-dashed line in the figures is installed adjacent to the image recording device 40.

The image recording device 40 includes a casing 44, and one side of the casing 44 defines a film loading opening 46, and a mounting table 48 fits into the opening 46 so as to be freely drawn out. .

As shown in FIG. 3, inside the casing 44 is a suction device that constitutes a single-wafer mechanism. 50 are arranged. The suction cup 50 is displaced on a predetermined trajectory, as shown by the broken line in the figure, and a pair of conveying rollers 52 is provided close to the suction cup 50. One roller 54a constituting the roller pair 52 is configured to move forward and backward with respect to the other roller 54b, and the one roller 54a and the other roller 54b
and are in sliding contact with each other via a coil spring (not shown). A sprocket (not shown) is pivotally attached to the other roller 54b, and one end of a chain 56 is stretched around this sprocket. The other end of the chain 56 is engaged with a sprocket 60 that is pivotally attached to a rotational drive shaft (not shown) of a rotational drive source 58 .

Therefore, a sensor (not shown) is provided near the pair of rollers 52 to detect that the detection cartridge 30 and the film F have entered between the pair of rollers 52, and a sensor (not shown) is provided near the roller pair 54a. Means 62 are provided. This detection means 62 consists of one or more optical sensors 64,
The detection means 62 is positioned so that when the leading end of the film F enters between the pair of rollers 52, the optical sensor 64 faces each of the white portions 34a and black portions 34b forming the identification mark 32. In this case, the detection means 62 detects whether the film F contained in the package 10 is a predetermined film by detecting the white part 34a and the black part 34b of the identification mark 32 based on the difference in their reflectance. It is something to detect.

Guide plates 66a and 66b are disposed near the pair of rollers 52 to guide the film F conveyed by the pair of rollers 52 to a scanning recording section (not shown). In this case, the image recording device 40 includes the guide plates 66a and 66b.
After a desired image is recorded on the film F guided by and conveyed to a scanning recording section (not shown), the film F is conveyed to an automatic developing device 42 .

Next, the sheet film package 10 is transferred to the image recording device 4.
The operation of loading the 0 is explained below.

As shown in FIG. 2, the mounting table 48 constituting the image recording device 40 is pulled out, the film package 10 is loaded into the opening of the mounting table 48, and one end 16a of the light shielding member 12 is closed. It is exposed to the outside from the mounting table 48. In this state, the mounting table 48 is inserted into the image recording device 40. Furthermore, the other end 16b of the light shielding member 12
After cutting with a cutter means or the like, 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 plurality of films F and the detection sheet 30 placed on the uppermost film F are loaded onto the mounting table 48 while being protected by the cover paper 14.

Next, the single-feed mechanism is driven to bring the suction cup 50 into contact with the uppermost detection sheet body 30 stacked in the mounting table 48, and a vacuum generator (not shown) is driven to cause the suction cup 50 to The detection sheet body 30 is attracted. Then, the suction cup 50 is displaced onto the trajectory shown by the broken line in FIG.
0 is held between a pair of rollers 52.

At this time, it is detected through a sensor (not shown) disposed close to the pair of rollers 52 that the detection cartridge 30 is held between the pair of rollers 52, and the detection means 62 is thereby driven. be done.

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 black portion 34b of the identification mark 32 are detected based on the strength 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, if 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 cup 50 is moved under the action of the sheet-fed mechanism. The detection sheet body 30 held by suction is returned to the mounting table 48 .

Therefore, the operator only has to pull out the mounting table 48, take out the film F, and load a new package 10 onto the mounting table 48.

On the other hand, when it is confirmed through the detection means 62 that a predetermined film F is loaded in the image recording device 40, the rotational drive source 58 is driven to rotate the sprocket) 60 and engage the sprocket) 60. The pair of rollers 52 is rotationally driven in the direction of the arrow via a chain 56. Therefore, the detection sheet body 30 held between the roller pair 52 is
6a and 66b, it is conveyed to a scanning recording section (not shown), and further sent out to the automatic developing device 42 side.

Next, the films F stacked on the mounting table 48 are fed one by one through the suction cup 50 under the driving action of the sheet feeding mechanism, and the films F are sandwiched between the pair of rollers 52 . Then, the film F is conveyed to a scanning recording section (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 for development processing.

Note that after all the films F have been loaded from the mounting table 48 and a predetermined image recording operation has been performed on the films F, the driving of the image recording device 40 is stopped, and the mounting table 48 is pulled out. A new unexposed film F may be loaded as necessary.

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

That is, in the sheet film package IO, a detection sheet 30 is placed on the film F, and an identification mark 32 as identification information is provided on one edge of the detection sheet 30. On the other hand, the image recording device 40 into which the sheet film package 10 is loaded is provided with a detection means 62 consisting of a plurality of reflective optical sensors 64 in close proximity to one roller 54a constituting the roller pair 52. Under the suction action of the suction cup 50 constituting the single-fed mechanism, the detection sheet 30 is first 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
will be driven. Here, as shown in FIG. 4, when the end of the detection sheet 30 is held between the roller pair 52, the identification mark 32 provided on the detection sheet 30 is located at a position corresponding to the detection means 62. is positioned.

Therefore, the detection light from each optical sensor 64 constituting the detection means 62 is accurately irradiated onto the white part 34a and the black part 34b of the identification mark 32, and the type of film F displayed on the identification mark 32 can be detected. It can be read reliably.

In this manner, the identification mark 32 is detected via the detection means 62 while the detection sheet 30 is being conveyed, that is, when the leading end of the detection sheet 30 enters the roller pair 52. Therefore, for example, even if the sheet film packaging body 10 is not accurately positioned with respect to the mounting table 48, the identification mark 32 of the detection sheet body 30 can be reliably positioned with respect to the detection means 62, and the film F can record an image. It becomes possible to accurately detect whether or not the device is compatible with the device 40. Moreover, since the detection sheet 30 is housed within the sheet film package 10, the identification mark 32 of the detection sheet 30 is not damaged. That is, for example, if the identification mark 32 is provided on the sheet film package 10, the sheet film package 10 itself will be damaged during transportation, etc., and the identification mark 32 will be unnecessarily scratched. There is a risk of detection.

Further, when the identification mark 32 is attached to the sheet film package 10, the printed pattern of the sheet film package 10 may have the same identification information as the identification mark 32, and the type of film F may be incorrectly detected. . Therefore, by using the detection sheet body 30, it is possible to reliably prevent image recording work from being performed on a film F that is not applicable via the image recording device 40, and - moreover, efficient image recording can be achieved. One of the benefits is that the work can be completed.

Furthermore, in this embodiment, there is no possibility that the film F will be loaded onto the mounting table 48 in an inverted state. That is, when the sheet film package 10 is loaded onto the mounting table 48 in an inverted state, the film F is first suction-held via the suction cup 50 under the driving action of the sheet-fed mechanism.

Then, when the film F enters the pair of rollers 52, the detection means 62 is driven and detection light is irradiated onto the film F from each optical sensor 64. 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 onto the mounting table 48 in an inverted state, thereby making it possible to prevent the inconvenience of the inverted film F being conveyed to a scanning recording section (not shown).

In the above embodiment, an example has been described in which the identification mark 32 is made up of displays with different reflectances, but displays with different transmittances may also be used. In this case, a well-known transmission type sensor may be used as the detection means. Alternatively, instead of providing the identification mark 32 on the detection sheet body 30, the transmittance or reflectance of the entire detection sheet body 30 can be measured by the film F.
It may be configured such that the type of film F is different for each type, and the type of film F is detected based on the difference in transmittance or reflectance.

[Effects of the Invention] As described above, according to the present invention, a plurality of sheet films are housed in a light shielding member in a light-tight manner, and a detection sheet body having identification information is mounted on the uppermost sheet film. On the other hand, the device for loading the sheet film is provided with a detection means for detecting the identification information. Therefore, after loading the sheet film package into the device, when the detection sheet is first taken out and placed in the conveyance system, the detection means detects the identification information of the detection sheet and records the image in the device. It is possible to detect whether or not a sheet film compatible with the above is loaded. In this way, since the identification information is detected via the detection means when the detection sheet is positioned in the transport system during its transport, it becomes possible to read the identification information accurately and easily.

Although the present invention has been described above with reference to preferred embodiments, the present invention is not limited to these embodiments.
Of course, various improvements and changes in design are possible without departing from the gist of the present invention.
