[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method and an apparatus for sheet-feeding a sheet body such as a photographic film or a stimulable phosphor sheet.

[0002]

2. Description of the Related Art For example, stimulable phosphors (stimulable phosphors)
There is known a system that once records radiation image information of a subject such as a human body, reproduces the radiation image information on a photographic photosensitive material such as a photographic film, or outputs a visible image on a CRT or the like. I have.

The stimulable phosphor is composed of radiation (X-ray, α-ray, γ
(E.g., a beam, an electron beam, or an ultraviolet ray), a part of the radiation energy is accumulated, and a phosphor that emits stimulated light in response to the accumulated energy when irradiated with excitation light such as visible light. The stimulable phosphor is usually formed in a sheet shape and used as a stimulable phosphor sheet, and the stimulable phosphor sheets are handled one by one in a cassette.

The above system includes, for example, a reading section for reading image information recorded on the stimulable phosphor sheet, and an erasing section for erasing image information remaining on the stimulable phosphor sheet after the reading process. Image information reading device is employed. In this image information reading apparatus, a cassette accommodating a stimulable phosphor sheet on which radiation image information of a subject is recorded by an external photographing device is inserted into a loading section. Next, with the cassette opened, the stimulable phosphor sheet is taken out of the cassette under the action of the sheet unit sheet mechanism, and the stimulable phosphor sheet is transported to the reading unit via the sheet transport mechanism. Is done. The stimulable phosphor sheet subjected to the reading process of the radiation image information in the reading unit, after the erasing process of the afterimage is performed in the erasing unit,
It is accommodated in a cassette arranged in the loading section.

On the other hand, the above-mentioned system uses an image information reproducing apparatus for recording and reproducing radiation image information on a photographic photosensitive material such as a photographic film. In this image information reproducing apparatus, after a magazine containing a plurality of photographic photosensitive materials is placed in the loading section, the photographic photosensitive materials are taken out of the magazine one by one under the action of a sheet-sheet-sheet-feeding mechanism. The sheet is transferred to the sheet conveying mechanism, and transferred to the recording unit via the sheet conveying mechanism. In the recording unit, radiation image information obtained from the stimulable phosphor sheet is exposed and recorded on a photographic photosensitive material by irradiation with laser light or the like.

[0006]

Incidentally, the sheet body sheet feeding mechanism usually enters a cassette or a magazine (hereinafter, referred to as a container) loaded in a loading section and receives a stimulable phosphor sheet or a photographic film (hereinafter, referred to as a container). , A sheet body). Then, by moving the suction disk between the inside of the container and the sheet conveying mechanism, the sheet adsorbed by the suction disk is sent to the sheet conveying mechanism.

However, when the container is loaded in the loading section, the sheet members are arranged in various postures in the container, and for example, there are cases where the sheet member is rotated or tilted in the width direction. is there. Therefore, in the above-described sheet-body sheet-feeding mechanism, the suction body positions the sheet body before transporting the sheet body to the reading unit or the recording unit so that the suction body sucks and takes out the sheet body in the posture in the container. A sheet width adjusting mechanism is provided.

In this sheet body width shifting mechanism, the sheet body is temporarily stopped, then the nip of the pair of conveying rollers constituting the sheet body conveying mechanism is released, and the width of the sheet body is moved via the sheet body holding member. A structure is adopted in which the sheet body is moved, and the sheet body is carried into a reading unit or a recording unit by nipping the pair of conveying rollers. As a result, a nip release mechanism and the like are required in addition to the sheet body width shifting mechanism, which leads to a problem that the structure is considerably complicated and large, and that much time is required for the sheet body positioning process.

SUMMARY OF THE INVENTION The present invention solves this kind of problem, and a sheet-sheet-feeding method and a sheet-sheet-sheet-feeding method capable of smoothly and reliably sending out a sheet from a container to a sheet-sheet conveying mechanism with a simple process and configuration. It is intended to provide a device.

In the method and the apparatus for sheet-fed sheet according to the present invention, when the sheet contained in the container is adsorbed by the suction plate and taken out from the container, the container and the sheet are removed. The position regulating member advances between itself and the body transport mechanism. For this reason, the leading end in the transport direction of the sheet body sucked and held by the suction board abuts on the position regulating member, and the positioning of the sheet body is performed. Next, after the position regulating member is retracted, the sheet body sucked and held by the suction board is sent out to the sheet body transport mechanism.

[0011] With this, the sheet body can be reliably positioned in a desired posture by a simple process and configuration, and then sent out to the sheet body transport mechanism, thereby effectively preventing poor conveyance of the sheet body. it can. In addition, a structure for widening the sheet body immediately before the reading unit and the recording unit is not required, so that the manufacturing cost is greatly reduced, and the processing time of the sheet body is reduced at once, so that efficient processing is performed. Will be possible.

Further, the position regulating member has a horizontal regulating surface and a width regulating surface, and the positioning of the sheet body in the inclination direction and the width direction can be easily performed through the position regulating member, and the configuration is simplified at a stroke. Become

Further, a negative pressure control means is provided for making the sheet body relatively movable with respect to the suction plate when the leading end of the sheet body in the conveying direction comes into contact with the position regulating member. The negative pressure control means includes a pressure sensor that detects a suction force of the sheet body by the suction disk, and a control unit that controls an output of a pump that communicates with the suction disk based on a signal from the pressure sensor. The sheet body is held with a minimum necessary suction force via the suction plate.

Therefore, when the sheet member comes into contact with the position regulating member, the sheet member is smoothly moved relative to the suction plate while being held by the suction plate, and the positioning process of the sheet member is smoothly performed. Will be performed. In this case, a curved surface is provided at the peripheral end of the cup portion constituting the suction disk, and the sliding operation between the suction disk and the sheet body is further easily and smoothly performed.

[0015] Further, there is provided a bracket for mounting the suction disk, and displacement means for moving the bracket integrally with the sheet member being sucked by the suction disk when the sheet member comes into contact with the position regulating member. I have. The displacement means has, for example, a clutch disposed between a single-wafer arm and a bracket for moving the suction disk along a desired trajectory, or a differential unit provided on the single-wafer arm. ,
With these, the bracket is rotated, and the suction disk can follow the movement of the sheet member. Further, by providing the displacement means with an elastic body for moving the bracket forward and backward in the width direction, it is possible to reliably absorb the movement of the sheet body in the width direction.

The operation 0 is described below in relation to the sheet-by-sheet method according to the present invention.

First, the stimulable phosphor sheet 32 on which radiation image information of a subject such as a human body is recorded by a photographing device (not shown) constitutes the image information reading device 12 in a state of being shielded from light in the cassette 16. The cassette is set in the cassette loading unit 18. At this time, the lid 48 of the cassette 16 is swung to a predetermined angular position by an unlocking means (not shown) provided in the cassette loading unit 18, and the opening 46 is opened to the sheet-sheet-feeding device 10. .

Next, under the driving action of the first motor 62 constituting the moving mechanism 54, the large-diameter pulley 68 rotates integrally with the drive shaft 66 via the small-diameter pulley 64 and the belt 70 in a predetermined direction. One end of an arm 72 is fixed to the other end of the large-diameter pulley 68 and the drive shaft 66, and the arm 72 swings around the drive shaft 66 as a fulcrum.

The movable base 84 provided with 6 is provided with suction pads 50a, 50b.
Is moved via a bracket 88 along a trajectory inclined obliquely downward from above with respect to the adsorption surface of the stimulable phosphor sheet 32 in the cassette 16 (see FIG. 8).

With the suction surfaces of the stimulable phosphor sheet 32 being sucked by the suction disks 50a and 50b, the moving mechanism 5 is moved.
4 is driven in the reverse direction. For this reason, the suction disks 50a and 50b move from the inside of the cassette 16 toward the sheet body transport mechanism 20 integrally with the movable base 84 and the bracket 88 under the swinging motion of the arm 72, and the stimulable phosphor in the cassette 16 is moved. The sheet 32 is sucked by the suction disks 50a and 50b and taken out from the opening 46 of the cassette 16 (see FIG. 9).

At this time, as shown in FIGS. 5 and 6, a solenoid 112 constituting the sheet positioning mechanism 58 is driven, and the position regulating member 56 is moved to the stimulable phosphor sheet 32.
Are arranged on the transport path. Therefore, the suction cup 50a,
The leading end 32a in the transport direction of the stimulable phosphor sheet 32 held by suction at 50b is positioned on the horizontal regulating surface 1 of the position regulating member 56.
06, and the tilt adjustment is performed along the arrow C direction. On the other hand, both side portions of the stimulable phosphor sheet 32 are guided by the guide surfaces 110a and 110b so that the width regulating surfaces 108a and
Adjustment of the width position is performed by abutting on 108b.

In this case, in the first embodiment, as shown in FIG. 4, the negative pressure control means 100 is provided, and the adsorbing force of the stimulable phosphor sheet 32 by the adsorbing plates 50a and 50b is minimized. Is controlled to be the value of Specifically, as shown in FIG. 7, when the pump 96 is turned on, a pressure sensor 102 provided in a pipe 94 that communicates the pump 96 with the suction plates 50a and 50b causes the pressure sensors 102 to be connected to the suction plates 50a and 50b. And the detection signal is sent to the control unit 104.

In the control unit 104, the suction boards 50a, 50b
When the vacuum pressure becomes equal to or higher than a predetermined pressure, the pump 96 is turned off, while when the vacuum pressure becomes equal to or lower than the predetermined pressure, the pump 96 is turned on. Thereby, the suction disks 50a, 50
b is maintained at a minimum value, and the stimulable phosphor sheet 32 sucked and held by the suction disks 50a and 50b abuts the position regulating member 56 to adjust the inclination and the width position. In this case, the stimulable phosphor sheet 32 can be easily and smoothly moved with respect to the suction plates 50a and 50b. Therefore, an effect is obtained that the stimulable phosphor sheet 32 can be positioned smoothly and with high precision while being held by suction by the suction boards 50a and 50b.

Moreover, the cup portions 90a and 90b constituting the suction disks 50a and 50b are provided at their peripheral ends with curved surfaces 92a and 92b separated from the surface of the stimulable phosphor sheet 32 to be sucked. For this reason, when the stimulable phosphor sheet 32 moves with respect to the suction plates 50a and 50b,
No turning or the like occurs at 0a and 90b. By providing curved surfaces 92a and 92b in the cup portions 90a and 90b, the stimulable phosphor sheet 32 can be attached to the suction plates 50a and 90b.
The negative pressure control means 100 need not be used as long as it can move relatively smoothly with respect to 50b.

As described above, after the inclination and / or the width position of the stimulable phosphor sheet 32 held by the suction boards 50a and 50b is corrected through the sheet body positioning mechanism 58, the solenoid 112 is adjusted. The position regulating member 56 is retracted out of the conveyance path of the stimulable phosphor sheet 32 via (see the two-dot chain line in FIG. 6). Then, the moving mechanism 54
Of the stimulable phosphor sheet 32 in the transport direction 3
2a is a roller pair 120 constituting the sheet conveying mechanism 20
At about the same time, the leak valve 98 is opened, and the suction and holding of the stimulable phosphor sheet 32 by the suction boards 50a and 50b is released.

Thus, the stimulable phosphor sheet 32 is
As shown in FIGS. 2 and 10, after being transferred to the transport system 22 via the roller pair 120, the sheet is once transported to the reading unit 26 through the erasing unit 24 under the action of the transport system 22. You. In the reading section 26, the stimulable phosphor sheet 3
The laser light L is main-scanned from the optical system 40 to the recording surface side of the stimulable phosphor sheet 32 while the laser beam 2 is conveyed in the direction of arrow A through the sub-scanning system 38 in the sub-scanning direction. Therefore, the radiation image information recorded on the stimulable phosphor sheet 32 is:
The light is read photoelectrically by the condensing system 42.

In this case, the stimulable phosphor sheet 32 is sent to the reading section 26 via the transport system 22 after the inclination and / or width position is corrected via the sheet body positioning mechanism 58. For this reason, a structure for releasing the nip of the roller pair 28 constituting the transport system 22 becomes unnecessary, in addition to a structure for shifting the stimulable phosphor sheet 32 immediately before the reading unit 26. This has the advantages that the structure is simplified at once, the cost of the entire image information reading device 12 can be reduced, and the processing capability can be effectively improved.

After the reading section 26 reads the radiation image information, the stimulable phosphor sheet 32 is conveyed in the reverse direction via the conveying system 22 and moves to the upper side in the vertical direction. The remaining radiation image information is erased through the erasing light source 30. After the stimulable phosphor sheet 32 is further fed into the cassette 16, the cassette 16 is pulled out from the cassette loading section 18. At this time, since the cover 48 is closed to the housing 44 side via a cover means (not shown), the cassette 16
It is taken out of the image information reading device 12 with the opening 46 shielded from light.
