Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention belongs to the field of medical equipment for diagnosis, and more specifically, for example, uses a stimulable phosphor sheet for recording and reproducing radiographic images in large quantities and continuously. The present invention relates to a radiological diagnostic apparatus that performs tlltJJ ray imaging.

[Technical background of the invention and its problems] Certain types of phosphors are exposed to radiation (X-rays, α-rays, β-rays.

When the phosphor is irradiated with Y-rays, ultraviolet rays, etc., part of the energy of this emitted @ ray is accumulated in the phosphor, and then when the phosphor is irradiated with excitation light such as visible light, it will react according to the accumulated energy. Therefore, the phosphor exhibits stimulated luminescence. A phosphor exhibiting such properties is called a stimulable phosphor.

Using this stimulable phosphor, radiation image information transmitted through the human body, etc. is recorded on a sheet of stimulable phosphor, which is then scanned with excitation light to produce stimulated luminescence. A method has been proposed in which the image signal is read out to obtain an image signal, and the image signal is processed to obtain an image suitable for diagnosis.

This final image may be reproduced as a hard copy or on a CRT. In such a radiation image recording and reproducing method, a stimulable phosphor sheet (strictly speaking, in addition to a panel-shaped sheet, a drum-shaped sheet, etc.) is used.
It can take various forms, but here they are collectively referred to as:
This will be referred to as the "image plate" and will be referred to as I.
It will be abbreviated as 'P. ) has the property of being able to be reused approximately 1,000 times by performing readout irradiation for photostimulation after radiography, and after the recorded image is read out, it is considered to be highly economical. , has come to be used in radiological diagnostic equipment.

Conventionally, the IPs on which radiation image information is recorded are sequentially 1
The sheets are stacked one by one and stored in a storage magazine, and when the storage magazine is full, the storage magazine is taken out and used for readout irradiation for photosensing. Then, once the image is recorded, the storage magazine is removed from the device, as complete light shielding is required for IP.
After that, the structure is such that no light leaks to the internal IP when it is transported.

By the way, when the storage magazine is transported, the IP loaded inside must not move and damage the phosphor layer. For this purpose, it is necessary to make the size of the storage portion of the storage magazine equal to the size of the IP and to reduce the allowable range in which the IP can move.

However, if the size of the accommodating portion is made equal to the size of the IP as described above, an opening large enough to take in the IP must be provided. Conventionally, it has been difficult to completely shield the large opening from light, so no consideration has been taken to restrict the movement of the IP within the storage magazine.

By the way, the conventional tick-up magazine for storing photographed IPs was larger than the size of the IP, so by transporting the photographed IP and sending it to the tick-up magazine, it is possible to store the photographed IP. IP
I was able to easily store it in the tick-up magazine. However, when carrying a tick-up magazine containing a large number of imaged IPs from a radiological diagnostic device and attaching it to the first reading device that reads the stored information, the size of the tick-up magazine is smaller than that of the tick-up magazine. As the IP moves within the tick-up magazine, many stacked IPs rub against each other and the I
There are problems in that the surface of the IP may be damaged or the edge may come into contact with the pick-up magazine, resulting in inconvenience to the stored information or shortening the life of the IP that is used repeatedly.

Therefore, we made the size of the storage and loading portion of the pickup magazine almost the same as the size of the IP, and
If a flexible member with a large amount of deformation is installed on the inner circumferential side of the P storage and loading section, the photographed IP can be stored in the tick-up magazine while being fixed by the flexible member on the circumferential side. Even when you carry the camera around, the IP that has already been photographed inside will not move.

However, in order to stack photographed IPs in the above-mentioned pick-up magazine in close contact with each other, the size of the storage and loading section of the pick-up magazine is almost the same as the IPs, so it is necessary to A device is required to push the photographed IP into the pick-up magazine in just the right condition from above the pick-up magazine.

[Object of the invention] The present invention has been made based on the above circumstances, and
The pickup magazine, which has a storage and loading area that is almost the same size as the camera, uses a simple mechanism to securely store the IP without damaging the surface of the photographed IP.
An object of the present invention is to provide a radiological diagnostic apparatus that can accommodate P.

[Summary of the Invention] The outline of the present invention for achieving the above object is to convey a stimulable phosphor sheet for recording and reproducing radiation images, take an image at a predetermined position, and then convey the photographed phosphor sheet again. ,
In a radiological diagnostic device that is pushed into a tick-up magazine from above from the feed mechanism and stored, there is a press mechanism driven by a motor, a presser plate that is pressed and moved by a suppressor mechanism, and a scanning movement that occurs as the presser plate moves. The present invention is characterized in that it comprises a barcode reader, and a feeding mechanism section that is driven by the motor to perform retracting movement via a cam.

.

13B and the corrugation member 16 are formed to guide the feed magazine 12 to the lowest layer of IPll loaded in the feed magazine 12. Further, a drive shaft 107 for moving the frame support rod 101 along the guide grooves 103, 103 is arranged parallel to the frame support rod 101.

As shown in FIG. 5(b), the delivery member 19
It consists of a pair of rollers 111, 111 mounted at positions corresponding to both ends in the middle direction of IPll, and a corrugation roller 112 mounted at a position corresponding to the center of the width direction of IPll. The roller pair 111.111 is the drive shaft 1

The operation and effects of the supply section 10 configured as described above will be explained with reference to FIGS. 6 and 7. First, IP
In order to take out ll, the first motor M1 is rotated forward,
Drive shaft 107. 1st. Second link plate 104.1
05, the frame support rod 101 is driven to move downward along the guide groove 103. When the frame 100 is moved downward together with the movement of the frame support rod 101, the suction pad 16a of the corrugation member 16 first comes into contact with the non-fluorescent surface (also referred to as the back surface) of the IP 11. Note that since the corrugation member 16 is attached with the coil spring 17 interposed, the frame 10
0 can be moved further down. When the frame body 100 is moved further downward, all the suction pads 13a, 13a,
13b, 13b.

16a comes into contact with the non-fluorescent surface of IPII, and at this position the forward rotational drive of the first motor M1 is stopped.

This state is shown in FIG. 6(a). In addition, FIG. 6 (a> is a view seen from the direction of taking out the IPll, and the suction pads 13a, 13a +' 16a are at the same surface height when the IPll is removed.
I am in contact with ll. Here, the vacuum pump 14 is driven to adsorb IPll. In addition, the suction pad 13a etc. are IP
Since the non-fluorescent surface of 11 is adsorbed, no adsorption marks or the like are left on the phosphor layer 11a. After this, the first motor M1 is driven to rotate in reverse to start the separation operation of IPll. The frame body 1 is rotated by driving the first motor M1 in reverse rotation.
00, the suction pad 13a initially.

Only 13a, 13b, and 13b are raised, and the suction pad 16a of the corrugation member 16 is urged downward by the urging force of the coil spring 17 and does not rise. As a result, when viewed in the width direction of IPll, Figure 6 (
As shown in b), only both ends of the IPII in the width direction are separated from other IPlls, and the central portion is projected downward by the corrugation member 16. That is, the IPll is formed in a wavy state in the width direction, and the undulation occurs throughout the lengthwise direction (direction along the extraction direction) of the IPll. In particular, the suction pads 13b, 13b prevent the IPll from being removed even in the longitudinal center portion of the IPll.
This effect is remarkable because both ends in the width direction are attracted. In this manner, by forming the IPll in a wavy shape in the width direction, the section modulus of the IPll becomes large, and sag does not occur when the IPll is separated and moved.

Therefore, even if the frame body 100 is further lifted upward, the adsorbed IPll is lifted in parallel to the non-adsorbed portion as shown in FIG.
It can be separated without contacting ll. As a result, the phosphor layer 11a is not damaged due to contact between the IPs 11 when taking out the IPs. In addition, as shown in FIG. 6(b), when the IPll separation operation starts, the IPll
By forming a wavy shape on the l, other excellent effects can also be obtained. That is, at the start of the separation operation,
First, both ends of the 1pii in the width direction are separated from the loose IPll, and an air layer is formed between them. In this way, by forming an air layer between other IPlls, it is possible to completely cut off contact with other IPlls, and it is possible to completely prevent two IPlls from being taken out due to pseudo adhesion caused by static electricity, etc. can.

In this way, one sheet of IPll separated and taken out by the pair of suction parts 13A, 13B and the corrugation member 16' is supplied to the delivery member 19 by moving the frame 100 along the guide groove 103. will be done. The tip of the IPll in the take-out direction is the drive roller 1.
11a, 111a and idle roller 11 lb, 1.
11'b, the IPll, which is held between the driving roller 111a and the idle roller 111h by the biasing force of the coil spring 115, receives the conveyance force of the driving roller 111a and is sent out to the other side. (See Figure 7). At this time, when transferring the IP 11 to the delivery member 19, the pair of suction parts 13A, 13B,
Corrugation member 16. Or sending member 19 and IPll
There are some areas where slippage may occur between the two. However, TPll
The drive roller 111a adsorbs the non-fluorescent surface of the
, 111a and the non-fluorescent surface side of IPll are brought into contact with each other, so that the fluorescent layer 11a is not scratched.

In addition, since a corrugation roller 112 is disposed on the delivery member 19 at a position corresponding to the center portion in the width direction of the IPll, the corrugation roller 112 is formed in a corrugated shape by the corrugation member 16. 112, a wavy shape is formed again. (See Figure 7). For this reason, the leading end side of the IPll in the take-out direction after passing through the sending member 19 is sent out without sagging, and the secondary erasing in the subsequent stage and the delivery to the special equipment section 30 can be performed smoothly.

The secondary erasing unit 20 irradiates the IPll with light using the light emitting lamp 22 as described above.

This is to eliminate noise that may have accumulated in the phosphor layer 11a of the RPII. That is, the IP that has been once erased externally before being supplied to this radiological diagnostic apparatus 1
The erasing process is completed again by performing the erasing process on 11 during transportation. The light emitting lamp 22 connected to the secondary erasing section 20 is powered by an AC power source. Incidentally, in order to maintain the brightness and color temperature of the light-emitting lamp 22 constant and to achieve complete secondary erasure, the lamp load power must be kept constant. In this embodiment, feedback is performed to keep the effective value I of the lamp current (AC>1(t) constant), so that the lamp load power is kept constant.

Next, the configuration and operation of the special equipment section 30 will be explained.

The special equipment section 30 includes an outer belt 31 and an inner belt 32 that are joined to each other so as to sandwich and convey the IPll, and the outer belt 31 . Drive drums 33a and 33b that synchronize the inner bells 1 to 32 and rotate intermittently in one direction (in the direction of the arrow shown)
and 34a, 34b. The outer belt 31 and the inner belt 32 are stretched so that the lower ends on the side of the secondary eraser 20 are bent in an arc shape toward the secondary eraser 23 side along the arc-shaped guide piece 37. There is.

The length of the part where the outer belt 31 and the inner belt 32 that form the special part 30 are joined to each other is approximately the same as the length of the IP. In addition, the outer belt 31 and the inner belt 32
A standby sensor 36 is arranged at the upper end of the rPll to detect the tip of the rPll being transported. Based on the signal emitted from the standby sensor 36, the drive of the drive drums 33a, 33b and 34a, 34b is stopped.

Further, in response to a signal indicating that the previous IP in the boulder part 50 has returned to its original position from the imaging site and has been transferred to the storage section 60, the drive drums 33a, 33b, and 34
Driving of a and 34b is started again.

In addition, 35 is the outer belt 31 and the inner belt 3 which are stretched.
This is a driven drum that applies a tension of approximately 2 degrees.

Since the special equipment section 30 has the above configuration, the noise-eliminated JPll is held and conveyed by the outer belt 31 and the inner belt 32 while changing direction at the arc-shaped bent part, and the tip thereof is connected to the standby sensor 36. When you reach the
The driving of both the outer and inner belts 31 and 32 is stopped by a signal from the standby sensor 36, and the IP 11 is moved to the special equipment section 30.
Wait for a while. Both the outer and inner belts 3'l, 32, which have stopped driving, are connected to the previous I in the holder part 50.
When the photographing of P is completed and the transfer to the storage section 60 is started, driving is started again, and the photo is transferred to the holder part 50 through the light-shielding roller 42. At this time, the new IP from which the noise on the IP has been erased by the secondary erasing section 20 is transferred to the special equipment section 30.
He enters and waits there like last time. In this way, the noise-eliminated IPll is always on standby in front of the holder part 50, which is the imaging position, so that continuous X-ray imaging can be performed quickly and smoothly, and the imaging cycle time can be reduced. Shortening is possible. This is because in the conventional transport route, the film before and after shooting used part of the same transport route, so it was not possible to provide a special section as described above, but with the present invention, the IP before and after shooting Since they each pass through separate transport paths, the above-mentioned special equipment section 30 can be provided on the transport path between the secondary erasing section 20 and the holder part 50.

Next, the structure and operation of the light shielding section 40 will be explained with reference to FIG. 8.

The light shielding section 40 includes a guide plate 41 that guides the transport direction of the IPll, a light shielding roller 42 that is disposed in close contact with the guide plate 41, and a light shielding plate that abuts the guide plate 41 and the light shielding roller 42, respectively. 43a and 43b. As shown in FIGS. 8(a) and 8(b), the light-shielding roller 42 is formed by attaching a flexible member 42b made of foamed plastic (for example, urethane foam) with a large amount of deformation around the roller 42a, and a bearing 44. through shaft 4
5, it is rotatably supported. Light shielding, roller 42
The flexible member 42b that covers the surface of the roller 42a is in close contact with the side plates 46 on both sides that support the shaft 45.
Since the rotation of the light shielding roller 42 may cause wear, a wear-resistant sheet member 47 with a low coefficient of friction is attached to the portion in contact with the light-shielding roller 42. Further, the light shielding plate 43a,
43b is arranged so as to block light from areas other than the transport path of IPII. Note that a flaw detection device 48 is arranged near the light shielding roller 42 to detect flaws on the surface of the IPll that has passed through the light shielding roller 42.

Since the light-shielding unit 40 has the above-described configuration, the TPll that has been transported after secondary erasing enters the light-shielding roller 42 while being guided by the guide plate 41 with the surface of the transported TPll facing the light-shielding roller 42 side, and the light-shielding roller 42 is a holder part 50 which rotates according to the transport speed of the IP and is the next transport path.
Transfer to.

At this time, since the surface of the light-shielding roller 42 against which the surface of the IP hits is formed of the flexible member 42b, the surface of the light-shielding roller 42 is not damaged when the IPll passes through the light-shielding roller 42. Furthermore, since the flexible member 42b is formed of a material with a large amount of deformation, the flexible member 42b is deformed by the thickness of the IPII when passing through, and the light shielding roller 42 rotates while being pressed against the guide plate 41. , even while the IPll is being transported, the light from the secondary erasing section 20 can be completely blocked, and the photographed IP will not be affected.

Next, regarding the structure and operation of the holder part 50,
This will be explained with reference to FIGS. 9 and 10.

The holder part 50 consists of an upper belt 51 and a lower belt 52 that are joined to each other so as to sandwich and convey P11, and a third belt.
51 to the upper bell 1 and the lower belt 5 by the motor M3 of
drive rollers 53a, 53b, 54a, 54b that rotate synchronously in one direction (in the direction of the arrow shown); and an arc-shaped guide member 55 that bends both ends of the upper belt 51 and the lower belt 52 downward in an arc shape. , a tension roller 56a installed near the guide member 55 and abutting the upper belt 51 or the lower heald 52, respectively;
56b, 57a, and 57b. still,
Reference numeral 58 denotes a position sensor that detects the leading or trailing end of the IP that is held and conveyed by the upper belt 51 and the lower belt 52.

The upper belt 51 is made of an X-ray transparent material such as urethane, and as shown in FIG. 10, the length in the width direction perpendicular to the conveyance direction is approximately the same as the width of the IP. In other words, the upper belt 51 on the surface side of the IP that holds the IP is wide enough to cover the entire surface of the IP.

On the other hand, the lower belt 52 is composed of four narrow belts, and these four narrow belts are driven at the same speed by drive rollers 54a and 54b. .

Also, by arc-shaped guide members 55.55 arranged at both ends of the upper belt 51 and lower belt 52, bent portions 59. 59 is formed. The length between the curved portions 59 and 59 of both layers is I
The length is almost the same as that of P, and the front and rear ends of the IP can be held between the double-layer curved portions 59 and 59.

Tension rollers 56a, 56b and 57a.

57b is a rotatable driven pulley whose shaft is fitted into the receiving shaft portion 190, and near each receiving shaft portion 190, as shown in FIG. 9, an upper belt 51 and a lower belt 52 are provided.
A plurality of bearing parts 190A are arranged in parallel, and the position of the shaft can be varied in the direction of increasing or decreasing the tension of the belt. Each tension roller whose shaft is fitted into the bearing part 190 is connected to the other bearing part 190A by an operation lever (not shown).
The tension of each belt in the upper belt 51 or the lower belt 52 can be adjusted by fitting the belt into the belt. still,
The tension of the belt may be adjusted by detecting the optimum tension in advance and controlling the tension so that the tension is automatically varied to that tension.

The drive rollers 53a, 53b, 54a, 54b
is rotated based on the drive of the third motor M3. This third motor M3 is drive-controlled by the second conveyor belt drive control section 206.

Further, this holder part 50 includes the roller groups 53a, 53b, 54a, 54b, 5
6a, 56b, 57a, and 57b are held by the frame 180 that rotatably supports them. This frame 180
Sliding members 181 and 181 are fixed to both end sides of. The sliding member 181.1'81 is connected to the guide shaft 182.
．． 182, and is slidable along the guide shafts 182 and 182 by the fifth motor M5. Note that this fifth motor M5 is driven based on the drive control of the sliding drive control section 208.

The holder part 50 configured as described above drives the third motor M3 based on the control of the second conveyance belt drive control section 206 when the IPll is conveyed at high speed from the special equipment section 30. Drive rollers 53a, 53b, 54
a and 54b are rotated to sandwich and convey TPll between the upper belt 51 and the lower belt 52. At this time, the transported IPll changes the transport direction at the bending part 59,
The IPll will be transported with its surface facing upward.

Here, the IPll stops when the leading and trailing ends of the transported IP 11 reach the bending parts 59.59 at both ends, as will be described later. Since the tension is applied, the IPll conveyed by both the upper and lower belts 51, 52 is accurately stopped at a predetermined stop position, and the position does not shift. Therefore, the IPll stopped at this predetermined stop position is
This means that it is possible to move to a predetermined photographing position, which will be described later, without causing positional deviation. Further, the tension of each of the upper belt 51 and the lower belt 52 that hold the IPll is determined by the tension roller 56a.

The shafts of 56, b and 57a, 57b are connected to appropriate shaft receiving portions 19.
It can be changed by fitting into 0 or 190A, so
Can be adjusted to obtain optimal tension. Therefore, the IP can be appropriately held and transported without damaging the surface of the IP. Furthermore, the upper belt 51 covers the entire surface of the IP and moves to the photographing position, which will be described later.
Since the entire surface of P will be exposed to X-rays evenly,
The entire surface of the IP can be used as an effective area for imaging.Therefore, there is no area on the surface of the IP that is ineffective for imaging, and wasteful areas of the IP can be eliminated. IPl held between the upper belt 51 and the lower belt 52
1 is temporarily stopped at the center of the holder part 50 and then moved to the photographing position B. Here, IPll is
A position sensor 58 disposed at the bending part 59 on the front side of the conveyance stage among the bending parts 59.degree. Rotation information of the third motor M3, which is the drive source for the lower belt 52, is input from the rotary encoder 117.

Since the distance between the position sensor 58 and the stop position is known, the distance between the position sensor 58 and the conveyance end of the IPll is determined by the position sensor 58, which is necessary to drive the third motor M3 in order to reach the stop position. The number of pulses can be detected. Note that the position sensor 58 may be configured to detect the rear end of IPll.

The second conveyance belt drive control section 206 controls the third motor M3 in order to accurately stop the IPll at the stop position as described above. After the IPll is stopped at the central part of the holder part 50, the exposure button (not shown) is pressed down, and the fifth
The motor M5 is driven to move the holder portion 50 from the initial position A shown in FIG. 3 to the shadow position B, and xi imaging for IPll is executed. In addition, shooting position B
is a case where the entire IPll is exposed to X-rays, and when performing divided imaging, the sliding members 181 and 181 and the upper and lower belts 51 and 52 are driven so that the center of the divided plane is
What is necessary is just to set it so that it may be located directly under the wire tube 2. Note that the limit switch 184 detects that the holder portion 50 has reached the photographing position B. Here, the sequence control unit 201 has a timer function that starts timing when the secondary erasure of the IP is completed and resets the timing when the exposure button is pressed. Therefore, if the exposure button is not pressed down even after a predetermined period of time (3 to 4 hours) has elapsed after the start of time measurement, the sliding member 181 is not moved to the photographing position B and control is performed to proceed to the next sequence. As a result, the initial position A
X-ray imaging will not be performed on the RPII, which is kept on standby for a long time and has a large noise in the phosphor layer proportional to this time.

Therefore, clear images with less noise can be recorded. For IPlls for which X-ray imaging has been completed or for which a predetermined period of time has elapsed without X-ray imaging, the second conveyor belt drive control unit 206 starts driving the third motor M3 and transports the IPlls to the storage unit 60. I will do it. The second conveyor belt drive control unit 206 continuously drives the third motor M3 when the flaw detection device 48 provided on the front side of conveyance of the holder part 50 detects that there is a flaw in the IPll. Then, the IPll is carried out to the storage section 60 without being stopped at the stop position. As a result, no image is recorded on the scratched IPll, and it becomes possible to always record images that are useful for diagnosis. Next, the housing section 60
The structure, operation, and effects of this will be explained with reference to FIGS. 11 to 20.

FIGS. 13(a), (b), (c), and (d) regarding the operation of the pick-up magazine 65 configured as described above.
will be explained in addition to reference. Before operating this X-ray diagnostic apparatus, first, an empty pickup magazine 65 is attached to the main body of the apparatus. Further, a shutter member 130
is detached from the frame 120 so that the photographed IPll can be taken in.

In this state, the light shielding plates 142 and 143 are urged to rotate by the urging forces of the springs 144A and 144B, and the respective bent portions 142B and 14 of the light shielding plates 142 and 143
3B is a first plate provided on the top plate 120c of the frame 120. It will be locked in the second notches 121A and 121B (see FIG. 13(a)). Since the width of the bent portion 143A of the light shielding plate 143 is longer than the width of the moving path of the shutter member 130, even if the shutter member 130 is detached, the light shielding plate 143
This makes it possible to prevent light leakage from the moving path of the shutter part IJ130. Moreover, the bent portion 143
A is a second plate that is one step lower than the top plate 120c.
Since it comes into contact with the notch 121B, light leakage can be reliably prevented from this contact point. Further, since the first light shielding member 140A is provided between the front plate 120a and the second light shielding member 140B, the double light shielding member 140A is provided over the width of the light shielding plate 142 of the first light shielding member 140A. It is possible to completely block light from leaking to the IPlls loaded and housed inside.

Next, when the imaging operation of the X-ray diagnostic apparatus is started, the imaged IPlls are sequentially supplied one by one by the action of a pushing device, which will be described later, and the pickup magazine 65 is accommodated through the opening 120f of the frame 120. It will be loaded into the loading area. At this time, the bottom plate 12od of the frame 120
Since a guide 122 that comes into contact with the end surface of the IPll is provided upright, the IPll is loaded in an aligned state within the pick-up magazine 65. In addition, since the loading position of the IPll is regulated by the guide 122 in this way, when the pick-up magazine 65 is taken out from the main body of the device and transported, the loaded IPll can be prevented from moving, and the transport Sometimes IPll phosphor layer 1' 1

At this time, the moving tip of the shutter member 130 first moves toward the first light shielding member 140, as shown in FIG. 13(b).
A, the light shielding plate 142 is rotated against the biasing force of the spring 144A, and is removed from the first notch 121A.

The light shielding plate 142 is a light shielding plate 13 attached to the lower surface of the shutter member 130, as shown in FIG. 12 (1').
Since both ends are cut out beyond the narrow portion 133B of No. 3, the bent portion 142B of the light shielding plate 142 comes into direct contact with the lower surface of the shutter member 130. Therefore, light can be blocked over the range of contact between the bent portion 142B and the shutter member 130. Furthermore, the second light shielding member 14
Since 0B is still engaged with the second notch 121B, it is possible to block light over the entire width of the shutter member 130. Therefore, the center portion in the width direction of the shutter member 130 is located at the first. Second light shielding members 140A, 140
Double light shielding is possible with B, and light shielding is ensured at both ends by second light shielding members 140B. Next, the first

The second spring 1 of the torsion spring 154
54b is in contact with the lower part of the guide shaft 151a, and the end of the spring 154b is locked to the lower part of the stopper 152b. Due to this stopper 152b, when the guide shaft 151a is above a predetermined position, only the first spring 154a works to push the guide shaft 151a downward, and when the guide shaft 151a is below the predetermined position, the second spring 154a acts to push the guide shaft 151a downward. Only the spring 154b works to push the guide shaft 151a upward. The upper end of the guide frame 152 is connected to the fixed frame 153 by a spring 155, and the spring 155 allows the bin 1 protruding from the lower front side of the guide frame 152 to be connected to the fixed frame 153.

Chapter 18 Regarding the operation of the pushing device configured as described above
The explanation will be given with reference to FIG. 20 as well.

When the pickup magazine 65 is not set in the device, the composite support member 69 is tilted rearward by the spring 155 as shown in FIG. 18(a).

Therefore, at this time, the presser plate 66 is placed above the position where the pick-up magazine 65 is set. Next, when inserting the tick-up magazine 65,
As shown in FIG. 18(a), the pick-up magazine 65 pushes the bin 152C of the guide frame 152, and as shown in FIG. 18(b), the composite support member 69 is straightened by overcoming the force of the spring 155. Be in a standing position. At this time, as the guide frame 152 rotates, the presser plate 66 tends to lower due to the force of the first spring 154a, but a shutter 658 (the shutter member 130) for blocking light is set in the pickup magazine 65. Therefore, the guide shaft 151a is connected to the first spring 154.
The guide shaft 151a is pushed up by overcoming the force a. Next, when the shutter 65a is pulled out from the take-up magazine 65, the first spring 154
The guide shaft 151a returns to the predetermined position by the force a,
As shown in FIG. 18(C), the rear side of the presser plate 66 is
It will enter inside the pickup magazine 65. As a result, the IP sent out by the sending mechanism section 63
The tip can be reliably inserted into the back of the pick-up magazine 65 using the presser plate 66 as a guide. Incidentally, when the pick-up magazine 65 is to be pulled out of the apparatus, it can be easily carried out without getting caught on the holding plate 66 by performing the reverse process as described above.

Passing through the drive belt 61 and drive roller 62, the feed roller 1
As shown in FIG. 19(a), the tip of the IPll sent out by 64 is guided toward the back of the pick-up magazine 65 along the holding plate 66. Because the first
This is because, as shown in FIG. 6, by corrugating the IPll with the corrugation roller 167, the rigidity of the IPll in the transport direction is increased. At this time, the feed roller 164 on the driving side is IPll
Since the surface of the IP is in contact with the nip roller 166, which is the driven side, when starting rotation,
Even if it slips when stopped, the surface of the IP coating will not rub, so the surface of the IP coating on which the photographed image is recorded will not be scratched. Note that if the corrugation roller 167 is not provided, the rigidity of the IP in the transport direction will not be strengthened, so the 20th
As shown in the figure, due to the weight of the IPll, the newly inserted IPll hangs down on the back surface of the IP already housed in the pick-up magazine 65, and its surface is rubbed.

Next, when the drive shaft 156 is rotated by the fourth motor M4, the presser link 157 is rotated as shown in FIG. 19(b).
rotates, and the first presser part 15 in the seesaw part 158
9A pushes the presser plate 66, overcomes the force of the support spring 68, and rotates the presser plate 66 about the fulcrum 150A. At this time, the cam 17 rotates in synchronization with the drive shaft 156.
4, the nip roller 166 moves in the direction of the arrow P shown in the figure and retreats (see FIG. 15), so that the presser plate 66
By pushing l, the surface of the IPll will not be damaged by the nip roller 166. Then,
As shown in FIG. 19(C), when the drive shaft 156 is rotated in the direction of the arrow Q shown in the figure, the rear end of the IP
is pressed into the tick-up magazine 65 by.

Until this state is reached, the torsion spring 160A is attached to the fulcrum 150C rather than the support spring 68.
Since this is stronger, the seesaw portion 158 does not rotate and the presser plate 66 is held down by the first presser portion 159A.

Next, when the drive shaft 156 is further rotated in the direction of the arrow Q shown in the figure, the torsion spring 16 is rotated as shown in FIG. 19(d).
0A, the seesaw portion 158 rotates, and not only the first presser portion 159A but also the second presser portion 159B press the presser plate 6.
6, and the press plate 66 is pressed by both press parts 159A and 159B. Furthermore, the drive shaft 15
6, as shown in FIG. 19(e), the torsion spring 154b of the composite support member 69, which is stronger than the torsion spring 160A, is overcome and the rear side of the presser plate 66 also lowers, causing the presser plate 66 to move downward. Push in the entire back side of the IPll.

In this way, the holding plate 66 moves so as to gradually push the IP into the pick-up magazine 65 from the rear end to the front end, so that the photographed IP is reliably surrounded by the guide 122 in the pick-up magazine 65. It can be stored in the storage and loading area, and does not damage the surface of the IP.

The barcode reader 70 rotates around the fulcrum 150D as the presser plate 66 descends due to the force of a torsion spring 160B attached to the fulcrum 150D.
IP pushed into the tick-up magazine 65 by
The barcode written on the back of the ll is read to identify the correspondence between the photographed image data and the patient. At this time, since the arm 173 maintains a constant distance between the reading section 70a and the presser plate 66, the photographed IP is
Even if the barcodes are stacked one after another in the IP 5, the readable distance 71 between the reading unit 70a and the barcode written on the back of the IP located at the top is kept constant (see FIG. 17).
Since the reading unit 70a can be positioned at the barcode reader 70, the barcode can be reliably read.

Furthermore, since the bar code reader 70 rotates and scans around the fulcrum 150D as the presser plate 66 moves, it is possible to read the bar code multiple times by changing the reading line within the readable range 71. Even if there is small dust or dirt on one reading line and the barcode information is read incorrectly, the information can be read accurately using another reading line. In addition, in FIG. 17, 72 is a barcode label on which a barcode is written.

As described above, the pressing movement of the presser plate 66 and the nip roller 1
The three operations of the evacuation movement of the barcode reader 66 and the scanning movement of the barcode reader 70 can be reliably driven in synchronization using one fourth motor M4.
It is possible to reliably and smoothly load and store the IP in a pick-up magazine 65 having an accommodation/loading part of almost the same size as the photographed IP without damaging the surface, and also to read barcodes accurately.

After the photographed IPll is completely stored in the pick-up magazine 65 by the presser plate 66, the presser link attached to the drive shaft 156 is driven by the presser plate drive control unit 207 to reversely rotate the fourth motor M4. 157
rotates in the direction opposite to the direction of the arrow Q shown in the figure, and through the reverse process to the above process, the holding plate 66, nip roller 166, and barcode reader 70 each return to their original initial positions and read the next photographed IP. Tick up magazine 65
It will be prepared for storage inside.

Finally, the overall operation of the apparatus according to the embodiment of the present invention will be briefly explained.

The IPll set in the feed magazine 12 with its front side facing down is taken out by suction parts 13A and 13B in the takeout mechanism section 15 by vacuum suction on the back side of the IP. Extracted IP
ll is 2 with the surface facing down by the delivery member 19.
It is then transported to the erasing section 20, at which time the light emitting lamp 22 emits light and the surface of the material 11 is irradiated with light, thereby erasing the IP noise. The noise-eliminated IPll is the outer belt 31 and inner belt 32 that constitute the special equipment section 30.
As a result, the IP is held and conveyed while changing direction upward at the arc-shaped bent portion, and when the tip of the IPll reaches the standby sensor 36, the IP is temporarily put on standby in the special equipment section 30. After a predetermined period of time has elapsed, the IP that has been waiting is conveyed to the holder portion 50 through the light-shielding roller 42 while being guided by the guide plate 41 .

The IPII transported to a part of the holder is transported to a bending portion 59 at one end where the upper belt 51 and the lower belt 52 are bent into an arc shape.
The IP is conveyed while being held between both belts 51 and 52 while changing the conveyance direction so that the surface of the IP faces upward, and is stopped at a predetermined position by a position sensor 958. The IPll, which has stopped at a predetermined position, moves to the imaging position B, which is the position facing the X-ray tube 2, by moving the entire boulder part 50 toward the back of the apparatus, and captures the X-ray image transmitted through the subject. is IP
Ill be photographed on. After the photographing is completed, the entire holder portion 50 of the IPll returns to the original transport path by moving to the original initial position A.

Then, it is again conveyed while being held between the upper belt 51 and the lower belt 52, and is sent to the storage section 60 while changing direction downward and downward at the arc-shaped bent portion 59 at the other end.

Note that the IP for which a flaw is detected on the surface of the IPll by the flaw detection device 48 is transported to the storage section 60 without being subjected to the bottle-shaped operation.

The IPll sent to the storage section 60 is transferred to the drive belt 61
Then, the direction of the IP is reversed by the driving roller 62 and the IP is transported to the feed mechanism section 63 with the surface facing down. The IP that has passed through the feed mechanism section 63 is conveyed along the lower surface of the holding plate 66 to the rear side of the pick-up magazine 65, and then transferred to the press mechanism section 67.
The presser plate 66 moves downward due to the drive of the presser plate 6.
6 to press the entire back surface of the IP and store the IP in the storage/loading section in the pick-up magazine 65 with the front surface facing down.

After a predetermined number of photographed IPlls are stacked and stored in the pickup magazine 65 in this manner, the opening 120f of the pickup magazine 65 is closed with the shutter member 130 (shutter 65a) to block light. Tick-up magazine 6 shielded from light like this
5 from the device, insert it into another reading device,
The stored photographed IP is subjected to readout irradiation for photoexhaustion.

[Effects of the Invention] As described above in detail, according to the present invention, the press movement of the presser plate, the evacuation movement of the feed mechanism, and the scanning movement of the barcode reader can be performed synchronously and reliably by one motor. With a simple mechanism, the IP can be reliably stored without damaging the surface of the IP in a pick-up magazine that has a storage area that is approximately the same size as the IP that has already been photographed, and the barcode is accurate. can be read.
