Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a single-layer method for producing sheet bodies, and more specifically, for stacking and storing sheets in a magazine or the like by moving suction means such as suction cups forward and backward. After adsorbing and holding a sheet body such as a stimulable phosphor sheet, the conveyance means such as a pair of rollers is displaced toward the sheet body side and the conveyance means is brought into contact with the sheet body, thereby preventing the sheet from being produced in multiple sheets. The present invention relates to a single sheet wafer method that allows a plurality of sheet wafers to be stopped without complicating the configuration of a single wafer mechanism by receiving and transferring the sheet body from the suction means to the conveying means.

[Background of the Invention] Recently, a radiation image recording and reproducing system that obtains a radiation image of a subject using a stimulable phosphor (stimulable phosphor) has been attracting attention. Here, stimulable phosphor refers to radiation (X-rays, α
When irradiated with rays, β rays, γ rays, electron beams, ultraviolet rays, etc., a part of this radiation energy is accumulated, and when excitation light such as visible light is irradiated later, stimulated luminescence light is generated depending on the accumulated energy. A phosphor that produces

The radiation image recording and reproducing system described above utilizes this stimulable phosphor, and the radiation image information of a subject such as a human body is stored on a sheet having a layer of stimulable phosphor (hereinafter referred to as a ``stimulable phosphor sheet''). This stimulable phosphor sheet is scanned with excitation light such as a laser beam to generate stimulated luminescent light, and the stimulated luminescent light is read photoelectrically to obtain an electrical signal. Based on this electrical signal, the radiation image of the subject is output as a visible image to a recording material such as a photographic light-sensitive material or to a display device such as a CRT. Note that, as described above, the expression of a visible image on a recording material such as a photosensitive material or a display device such as a CRT is referred to as reproduction.

Therefore, in such a radiographic image recording and reproducing system, an image reading device that reads a radiographic image from a stimulable phosphor notebook in which the radiographic image is stored and recorded specifically reads the radiographic image using the following method. There is.

That is, a stimulable phosphor sheet 2 is scanned one-dimensionally with a light beam such as a laser beam, and the stimulated luminescent light emitted thereby is detected in time series with a photodetector such as a photomultiplier to create an image. get information. and the light beam l,
Two-dimensional scanning usually involves performing sub-scanning by mechanically transporting the stimulable phosphor sort in one direction, and -
This is achieved by performing main scanning by irradiating a light beam polarized in a direction dimensionally perpendicular to the sorting transport direction.

In this case, after image information has been accumulated and recorded, a plurality of the stimulable phosphors are stacked and stored in a magazine and loaded into an image reading device. .

Then, the sorted stimulable phosphors are taken out one by one through a sheet-feeding mechanism including a suction cup, etc., and then subjected to an image reading operation.

By the way, as mentioned above, the sorted stimulable phosphors taken out by the single-wafer mechanism are stored in layers in the magazine, so that the sorted phosphors taken out by the single-wafer mechanism are stored in a stacked manner in a magazine. may be in close contact with other stimulable phosphors that are adjacent to each other. Therefore, when a sort of stimulable phosphor is taken out from a magazine via a suction cup, other sorts of stimulable phosphor adjacent to the stimulable phosphor sort are in close contact with the stimulable phosphor sort, and multiple sheets of stimulable phosphor are simultaneously removed from the magazine. There is a risk that this may occur. Therefore, in order to reliably take out the stimulable phosphor sheets stored in the magazine one by one, a method is adopted in which the stimulable phosphor sheets are stirred to be taken out from the magazine.

However, according to this method, in addition to the means for displacing the sorted stimulable phosphor sheets sheeted into the single sheet mechanism via the suction cup on a predetermined trajectory in order to supply the sheets of stimulable phosphor sort to the conveyance means etc. It is necessary to provide means for performing a stirring action that prevents single sheets. Therefore, the single wafer mechanism itself has become extremely complicated.

[Object of the Invention] The present invention has been made in order to overcome the above-mentioned disadvantages, and when stacking and storing stimulable phosphor in a magazine or the like or when sheet bodies such as films are sheeted,
First, the sheet body is sucked and held by a suction means and taken out from the magazine, and then the sheet body is pressed and bent by a conveying means, thereby peeling a plurality of sheet bodies from each other. Then, by transporting the sorted bodies using the conveyance means, the single-fed sheet mechanism itself can be made extremely simple in structure, and the single-fed sheet body can be reliably fed one by one. The purpose is to provide.

[Means for Achieving the Object] In order to achieve the above object, the present invention provides a method for stacking and storing sheet bodies in a magazine or the like. a first step of taking out the sheet from the notebook body, a second step of bending the sheet by bringing a conveyance means for conveying the sheet body and the notebook body into contact with each other, and carrying out the sorted body by the conveyance means. and a third step of.

The image reading and reproducing apparatus to which the sheet wafer method according to the present embodiment is applied is basically constructed as described above, and its operation and effects will be explained next.

First, the magazine 18 is mounted on the movable table 16 provided in the first loading section 14. Next, the moving table 16 is displaced toward the upper right in FIG. 1, and the upper side of the magazine 18 that is engaged with the moving table 16 is positioned at a predetermined position, and the sheet body single feeding mechanism 30 is driven. .

That is, in FIG. 2, when the rotary drive shaft 36a is rotated in the direction of the arrow under the driving action of the first rotary drive source 36, the gear 38 pivotally attached to the rotary drive shaft 36a rotates. For this reason, gear 3
The rocking plate 40 connects to the rod 4 via a gear portion 42 meshing with the rod 8.
Rotate in the direction of the arrow around 4. At that time, the swing plate 4
The first guide pin 54 of the arm member 50 is inserted into the opening 48 of
When the swing plate 40 rotates in the direction of the arrow, the arm member 50 moves toward the magazine 18 under the guiding action of the guide groove 60a defined in the wall plate 58 and the first guide pin 54. Displace to the side. At that time, since the second guide pin 56 implanted in the support portion 52 of the arm member 50 is guided along the guide groove 60b of the wall plate 58, the arm member 50
There is no problem such as unnecessary rotation of 0.

When the arm member 50 is displaced toward the magazine 18 and the suction cup 64 comes into contact with the stimulable phosphor sheet (S) via the tube body 62 held therein, the suction cup 64 is moved under the driving action of a vacuum generator (not shown). The stimulable phosphor sheet S is sucked through the suction cup 64. Therefore, when the rotary drive shaft 36a and the gear 38 are rotated in the direction opposite to the arrow under the driving action of the first rotary drive source 36, the rocking plate 40 is rotated through the gear portion 42 that meshes with the gear 38. It rotates about 44 in the opposite direction of the arrow. Therefore, the arm member 50 is connected to the first and second
The end of the stimulable phosphor sheet (S) is displaced away from the magazine 18 under the guiding action of the guide pins 54, 56 and the guide grooves 60a, 60b, and is held by the suction cup 64. It will be taken out upwards. At this time, the first rotary drive source 36 is activated to stop the stimulable phosphor sheet S, which is sucked and held by the suction cup 64, at a position where it can come into contact with the drive roller 88 forming the roller pair 86.

Therefore, when the rotary drive shaft 72a and the disc 74 are rotated integrally in the direction of the arrow under the driving action of the second rotary drive source 72, they are engaged with the edge of the disc 74 via the pin 76. The link piece 78 is displaced toward the magazine 18 side. For this reason,

The drive roller 88 constituting the roller pair 86 comes into contact with the stimulable phosphor sheet S.

Substantially, when the drive roller 88 comes into pressure contact with the stimulable phosphor sheet S, the end portion of the stimulable phosphor sheet S is bent (see FIG. 3a), so that the stimulable phosphor sheet S is bent. Even if multiple sheets of stimulable phosphor sheet S are placed in close contact with the body sheet S, the stimulable phosphor sheet S that is not held by the suction cup 64 may fall off and displace the magazine. It will be stored again in 18. In other words, it is possible to prevent two sheets from forming.

Next, the disc 74 is further rotated in the direction of the arrow under the driving action of the second rotational drive #72, and the link piece 7

The roller pair 86 is separated from the multilayer phosphor sheet S.

Next, the first rotational drive source 36 is driven again to further rotate the rotational drive shaft 36a and the gear 38 in the direction opposite to the arrow. As a result, the suction cup 64 has the guide grooves 60a, 6
It is again displaced upwardly along 0b.

Then, the stimulable phosphor sheet S attracted by the suction cup 64 is moved to a position where it can be held by the pair of rollers 86, and the first rotational drive source 36 is stopped.

Next, the roller pair 86 is driven by the second rotary drive source 72 in the same manner as described above to move the disc 74, the link piece 78, and the rod 8.
0. It moves to the suction cup 64 side via the mounting plate 84 and the like.

At this time, when the drive roller 88 is rotated in the direction of the arrow under the driving action of a rotational drive source (not shown), and the nimp roller 90 in sliding contact therewith is rotated in the direction of the arrow, the roller pair 86 is suctioned and held by the suction cup 64. The ends of the stimulable phosphor sheet 8 are held between them (see Figure 3). and,
If the drive of the vacuum generator (not shown) is stopped, the suction cup 64
The suction and holding effect of the stimulable phosphor sheet S is released, and the stimulable phosphor sheet S is held only by the pair of rollers 86.

Here, the link piece 78 is again pulled in the direction away from the magazine 18 via the disc 74 and the pin 76 under the driving action of the second rotational drive #72. Therefore, the link piece 78
The lot 80 that is attached to is displaced in the direction away from the magazine 18 along the guide groove 82, while the roller pair 8G moves toward the first conveyance system 96 side while holding the stimulable phosphor sheet S. (See Figure 3C). As a result, the stimulable phosphor sheet S is conveyed via the drive roller 88 and the nip roller 90 rotating in the direction of the arrow while being sandwiched between the first conveyor belt 100 and the drum 98 that constitute the first conveyance system 96. Become.

In the first conveyance system 96, the stimulable phosphor sheet S is sandwiched between the drum 98 and the second conveyance belt 102 and conveyed vertically downward, and then from the roller pair 126 to the fifth conveyance belt of the second conveyance system 128. 130 and the sixth conveyor belt 132

At this time, the second switching guide member 138 disposed in the second conveyance system 128 is oscillated in the direction shown by the broken line in FIG. The sheet is received in the sheet receiving portion 144 of the stacker 142 through the sheet receiving portion 144 of the stacker 142.

Next, the stacker 142 is raised and lowered to
42 and on which a predetermined image has been recorded, the stimulable phosphor sheet S is selected, and is fed to the second conveyance system 128 via a pair of rollers 140. and transport the stimulable phosphor sheet S downward. At this time, the movable guide plates 146a and 146b are swung to the positions indicated by the two-dot chain lines in the figure. As a result, the stimulable phosphor sheets S)
is fed into the gap defined by. In this case, the stimulable phosphor sheet S taken out from the magazine 18 is directly transferred to the movable guide plates 146a and 14 by the second conveyance system 128.
Of course, it may also be fed into the gap defined by 6b.

The stimulable phosphor sheet) S fed between the movable guide plates 146a and 146b is held between a pair of rollers 148, and is moved between the guide plates 150a and 150a under the driving action of the pair of rollers 148.
It is transferred to the sub-scanning conveyance means 152 via 50b. In the sub-scanning conveyance means 152, the stimulable phosphor sheet S is conveyed in the direction opposite to the arrow B under the action of the sub-scanning conveyance belt 154, and then fed onto the guide F plate 160. When the rear end side of the stimulable phosphor sheet (S) passes through the laser beam scanning area by the image reading and recording mechanism 164, the sub-scanning conveyor belt 154 is rotated in the opposite direction, and the stimulable phosphor sheet ) S is conveyed in the sub-scanning direction in the direction of arrow B. At this time, a vacuum pump (not shown) is driven, and the stimulable phosphor sheet S is suctioned and held by the first suction box 156 and the second suction box 158 on the sub-scanning conveyor belt 154 side.

In this way, the stimulable phosphor sheet S is sub-scanned and conveyed in the direction of arrow B, and the image reading and recording mechanism 164 is driven to reflect the laser light 168 emitted from the laser light source 166 by the mirrors 170 and 174. to reach the galvanometer mirror 176, and this galvanometer mirror 17

Similarly, the film F is transferred to the sub-scanning conveyor belt 1 under the suction action of the first and second suction boxes 156 and 158.
The paper is conveyed while being attracted to the 54 side.

When the film F is sub-scanned and conveyed in the direction of arrow B, the image reading and recording mechanism 164 is driven again. That is, laser light 168 derived from laser light source 166 is reflected by mirror 170 and reaches optical modulator 172 . Here, the optical modulator 172 includes an image information processing circuit 184.
The image signal data of the stimulable phosphor sheet S processed by and stored in a storage means (not shown) is sent.

Therefore, the laser beam 168 reaching the optical modulator 172
is modulated by the optical modulator 172 based on the image signal data, and this modulated laser beam 168 is reflected by the mirror 174 and transmitted to the galvanometer mirror 176.
reach. The laser beam 168 that has reached the galvanometer mirror 176 is deflected in the main scanning direction by its swinging action and is irradiated onto the film F.

In this way, since the film F is conveyed in the sub-scanning direction (direction of arrow B) and is main-scanned by the laser beam 168, the image read from the stimulable phosphor sheet S is reproduced on the film F. reach. Note that the film F
The photo multiplier 182 is kept active when the image is being played back.

After the image reproduction is completed, the film F is transferred to the sub-scanning transport means 15.

8 between the movable guide plates 146a and 146h. In this case, the movable guide plates 146a, 14
6b is oscillated to the position shown by the solid line in the figure, and the film F is transported to the film transport path 202 side. Therefore, the film F is attached to each roller pair 204a to 204a.
4d and guide plates 206a to 206f, and are fed into the receive magazine 210 through the opening 208 of the housing 12. Therefore, after a predetermined number of films F are stored in this receive magazine 210, the receive magazine 210 is removed from the housing 12 in a light-shielded state, and the films F are loaded into a developing device (not shown) and developed. .

In this case, according to the present embodiment, the stimulable phosphor sheets S stacked and stored in the magazine 18 are fed one by one by the sheet body sheet feeding mechanism 30, and the sheet body sheet S is The leaf mechanism 30 itself can be simplified.

That is, when sheeting the stimulable phosphor sheet S stored in the magazine 18, first, the sheet sheet sheeting mechanism 3
Under the driving action of the first rotary drive source 36 constituting the first rotary drive source 36, the stimulable phosphor sheet S is sucked and held by the suction cup 64 via the guide 46 and the arm member 50, and the end portion thereof is taken out from the magazine 18. Then, the first rotary drive source 36 is stopped at a position where the suction-held stimulable phosphor sheet S can come into contact with the drive roller 88 forming the roller pair 86. Next, the roller pair 86 is driven by the second rotary drive source 72.
The drive roller 88 constituting the roller pair 86 is brought into contact with the stimulable phosphor sheet S as shown in FIG. 3a. As a result, the end portion of the stimulable phosphor sheet S held by suction on the suction cup 64 is bent, and it is possible to prevent a plurality of sheets from being formed. Next, the roller pair 86 is driven by the second rotational drive source 72.
is first displaced in the direction away from the suction cup 64, and then the first rotary drive source 36 is driven again to displace the stimulable phosphor sheet S to a position where it can be held by the pair of rollers 86. Further, under the driving action of the second rotational drive source 72, the roller pair 8G is again displaced toward the suction cup 64 side, and the roller pair 86 is rotationally driven to sandwich the stimulable phosphor sheet) S (the third (see figure). Next, after stopping the drive of the vacuum generator (not shown), the roller pair 86 is moved away from the suction cup 64 under the driving action of the second rotary drive source 72, so that the stimulable phosphor sheet S is It will be sent out to the conveyance system 96 (see FIG. 3C).

As described above, according to the present invention, the sorting body single sheet mechanism 30 itself can be made extremely simple in structure, and moreover, by moving the roller pair 86 forward and backward relative to the suction cup 64, a plurality of sheets can be sorted. It can be prevented. Therefore, the stimulable phosphor sheets (S) stored in a stacked manner in the magazine 18
It becomes possible to reliably print one sheet at a time.

[Effects of the Invention] As described above, according to the present invention, a suction cup that can be displaced in a predetermined direction when stacking and storing sheet bodies such as stimulable phosphor sheets and films in a magazine or the like is provided. After the sheet body is suctioned and held by a suction means such as the like, a conveying means is brought into contact with an end of the sheet body, and the sheet body is bent. This makes it possible to separate a plurality of sheets from each other. Furthermore, the sheet body is carried out by the conveyance means. Therefore, by simply displacing the suction means and the conveying means along a predetermined trajectory when the sheet body is to be fed into single sheets, it is possible to prevent the sheet body from forming multiple sheets and to reliably take out the sheet body from a magazine, etc. . Moreover, since the displacement trajectory of the suction means and the conveyance means is extremely simple, an advantage is obtained that the sheet body single feeding mechanism itself can be considerably simplified.

Although the present invention has been described above with reference to preferred embodiments, the present invention is not limited to these embodiments.
For example, it is possible to apply the sheet-fed method according to the present invention to sheet-fed films, and it goes without saying that various improvements and changes in design are possible without departing from the gist of the present invention. It is.
