Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a magazine opening/closing mechanism for opening/closing the opening/closing lid of a magazine capable of storing sheet bodies constituting an image recording carrier such as stimulable phosphor sheets in a light-tight manner. Specifically, for example, in a radiation image recording device that records a radiation image of a subject by irradiating the image recording carrier with radiation, a drive mechanism opens the image recording carrier storage opening of the magazine in which the image recording carrier after image recording is stored. The present invention relates to a magazine opening/closing mechanism that allows the magazine to be opened and closed as necessary via the magazine.

2. Description of the Related Art X-ray imaging devices have been widely used in the past for irradiating a subject such as a human body with radiation and recording a radiation image on an X-ray film, which is useful for medical diagnosis and the like. In this case, the X-ray film is loaded into the X-ray imaging device in a light-shielded state, and a radiation image of the subject is recorded by directly irradiating the emulsion surface of the film with X-rays.

Incidentally, recently, a radiographic image recording and reproducing system that obtains a radiographic image of a subject using a storage phosphor (volatile luminescent material) has been developed, and it is becoming widespread, especially in the medical field as mentioned above. .

Here, a storage phosphor is a material that, when irradiated with radiation (X-rays, α-rays, β-rays, γ-rays, electron beams, ultraviolet rays, etc.), stores some of this radiation energy and later emits visible light, etc. A phosphor that generates stimulated luminescence according to the accumulated energy when irradiated with excitation light.

The radiation image recording and reproducing system described above utilizes this stimulable phosphor, and once the radiation image information of the human body etc. is recorded on a sheet having a layer of stimulable phosphor (hereinafter referred to as stimulable phosphor sheet or simply This stimulable phosphor sheet is scanned with excitation light such as a laser beam to generate stimulated luminescent light, and the resulting stimulated luminescent light is read photoelectrically to obtain an image signal. Based on this image signal, it is output as a visible image to a recording material such as a photographic window optical material, a CRT, or the like.

Here, the radiation image recording and reproducing system includes an image recording device to record a radiation image of the subject on the stimulable phosphor sheet. This device stores the sheets through a supply magazine or the like, takes out the sheets one by one using a sheet-fed mechanism including a suction cup, etc., transports the sheets to the photographing section, and passes the sheets through the subject in the photographing section. It is known that a sheet is irradiated with radiation to record a desired image, and then the sheet on which image information is recorded is stored in a receive magazine. Thereafter, the sheet on which the image information is recorded is photoelectrically read by an image reading device, and the image information is converted into a visible image by an image reproducing device and used for medical diagnosis, etc. become.

Incidentally, the stimulable phosphor sheet on which image information is recorded by the image recording device must not be irradiated with external light or the like. This is because the stimulable phosphor sheet is further exposed to the external light, and as a result, accurate image information cannot be obtained.

Therefore, the sheet after photographing needs to be held in a light-tight manner within the apparatus.

On the other hand, inside an image recording device, for example, light from an optical sensor that detects the position of a sheet may leak, or external light may enter from the loading port when loading a supply magazine that stores sheets in a stacked manner into the device. As a result, there is a possibility that the sheet after taking the radiographic image may be exposed to light. Therefore, it is conceivable to provide a light shielding means between the receiving magazine that stores the sheet and the photographing section to prevent the sheet from being exposed to light. In this case, the light shielding means includes the photographing section and the receiving section. A mechanism for opening and closing the sheet 1 general feed path provided between the magazine and the magazine is essential.

On the other hand, the receive magazine containing the sheets is transferred to an image reading device, and the image information stored on the sheets is read by the image reading device. must be transported to the equipment. Therefore, in order to make it possible to load a receive magazine for stacking and storing photographed sheets into the image reading device in a bright room, the receive magazine itself also needs a light shielding means.

In the end, in order to hold the sheet in a light-tight manner and to enable conveyance and loading in a brightly lit room, both the image recording device and the receive magazine must have a light-shielding means, which makes the structure extremely complicated and the manufacturing process difficult. This exposes disadvantages such as rising costs.

The present invention has been made to overcome the above-mentioned disadvantages, and includes an opening/closing means that engages with a lid member of a magazine in which an image recording carrier is stored in a light-tight state, and biases the opening/closing means. By opening and closing the lid member, the image recording carrier storage opening of the magazine can be opened and closed as necessary;
It is an object of the present invention to provide a magazine opening/closing mechanism with a simple structure that can effectively prevent the image recording carrier from being irradiated with unnecessary external light.

To achieve the above object, the present invention provides an opening/closing mechanism that engages with a lid member that closes the image recording carrier storage opening of a magazine that stores sheet-like image recording carriers stacked in a light-tight state, and opens and closes the lid member. and a driving means for operating the opening/closing member, when an image recording carrier with an image recorded thereon is fed to the magazine disposed corresponding to the image recording section,

The image recording device incorporating the magazine opening/closing mechanism according to this embodiment is basically configured as described above.
Next, its action and effects will be explained.

First, the supply magazine 102 containing a predetermined number of stimulable phosphor sheets S is loaded into the main body 16 of the apparatus through the loading port 18 . Next, when the servo motor 112 constituting the single wafer mechanism 110 is driven, the rotational drive shaft of the servo motor 112 rotates, thereby rotating the disc 118 and fitting the crank pin 120 provided on the disc 118. The first arm 122 swings toward the supply magazine 102. At this time, each suction cup 142a to 142c is pressed onto the surface of the sheet S, and suctions the sheet S under the driving action of a vacuum generator (not shown). Next, the disc 118 further rotates under the driving action of the servo motor 112, and the upper surface of the stimulable phosphor sheet S, which is suctioned and held by the suction cups 142a to 142c, comes into pressure contact with the roller 174.

Next, the servo motor 112 is driven to rotate the disc 118 in the opposite direction, and the rotary solenoid 1
50 is driven to engage the pin member 152 with the locking member 136, and the first arm 122 is swung again, thereby sandwiching the sheet S between the roller 174 and the pulleys 202a and 202b. By doing this, simultaneous conveyance of a plurality of sheets S is prevented. Here, when the torque motor 160 is driven, the ti motion arm 170 swings, and the roller 17
4 holds the sheet S together with conveyor belts 206a and 206b.

Therefore, under the driving action of a motor (not shown), the rotating shaft 204
The pulleys 202a and 202b are rotated by rotating the pulleys 202a and 202b. When the pulleys 202a and 202b rotate,
A conveyor belt 206a is stretched over these.

206b and the roller 174, the stimulable phosphor sheet S is first conveyed upward, and then the stimulable phosphor sheet S is conveyed upward via the conveyor belt 20
6a, 206b and a plurality of belts 214a to 214c
It is transported horizontally in a curved manner.

Therefore, the sheet S moving in the horizontal direction is irradiated with erasing light. That is, although the stimulable phosphor sheet S stored in the supply magazine 102 is irradiated with erasing light in advance to temporarily erase the radiation image remaining on the sheet S, the image is completely erased. There is a possibility that it has not been deleted.

For this reason, the afterimage on the sheet S is secondarily and completely erased by irradiating the sheet S immediately before the image is recorded with erasing light from the halogen lamp 234 constituting the erasing means 232.

After the erasing is completed, the stimulable phosphor sheet S is attached to the pulley 208.
a, 208b and the belts 230a to 230c, and are conveyed from the horizontal direction downward in the vertical direction, and are dropped and supplied between the respective plate bodies 308 and 310 constituting the pressure plate unit 306.

When the motor 318 is driven to rotate the rotary shaft 324 that engages with the motor 318, both ends of the rotary shaft 324 are rotated.

The fixed pinions 326a and 326b are attached to the rack member 3.
02a, 302b, and as a result, the motor 3
The second plate 310 to which 18 is fixed is displaced toward the first plate 308. Therefore, the stimulable phosphor sheet S is held in pressure contact with the first plate 308 and the second plate 310 via the pressing members 316a to 316d pressed by the springs 314a to 314d. Further, when the motor 318 is driven, the first plate 30B and the second plate 310 are integrally displaced in the direction of the arrow, and the drive of the motor 318 is stopped when reaching the imaging part of the imaging unit 300. do. Then, when a radiation generator (not shown) irradiates a subject in front of the imaging section 300 with radiation, a radiation image of the subject is recorded on the stimulable phosphor sheet S held between the pressure plate units 306. At this time, the driving means 336 is driven to swing the button key 334 to prevent scattering of the radiation.

After recording an image on the stimulable phosphor sheet S in this way, the motor 318 is driven to
326b is rotated to displace the pressure plate unit 306 in the direction opposite to the arrow, the support members 312a to 312d provided on the first temporary body 308 come into contact with the stopper members 328a to 328d of the apparatus main body 16. On the other hand, the second
The plate body 310 is independently displaced under the driving action of the motor 318 against the elastic force of each of the springs 314a to 314d, thereby defining a predetermined gap between the first plate body 308 and the second plate body. and stop. Therefore, after reading the barcode information provided on the sheet S through the barcode reading section 332, the pressure plate unit 3 is moved under the action of a driving means (not shown).
The table S on which the sheet S in 06 is placed is swung to cause the sheet S to fall into the storage section 400 side.

When the motor 404 constituting the conveyance system 402 is driven to rotate the first sprocket 406, the second sprocket 408 is rotated via the chain 410 suspended therefrom.
A roller 411 engaged with this second sprocket 408 rotates. Therefore, the stimulable phosphor sheet S is conveyed into the receive magazine 422 while being held between the conveyor belt 412 and nip rollers 418 and 420. At this time, if the nip roller 418 is separated from the roller 416 under the action of an actuator (not shown), the stimulable phosphor sheath) S falling onto the conveyance system 402 can be suitably nipped.

On the other hand, a receive magazine 422 is loaded into the storage section 400 from the receive magazine loading port 20 of the main body 16 of the apparatus. Here, a tapered member 456 having an inclined surface is attached to the side edge of the receive magazine 422, while a swinging member 464 constituting the magazine opening/closing mechanism according to the present invention is attached to the side edge of the receive magazine 422, as shown in FIG. To, receive magazine 42
It is arranged in an inclined state with respect to the side surface of No. 2. Therefore, when loading the receive magazine 422 into the storage section 400, the middle part of the swinging member 464 is displaced by the tapered member 456 toward the solenoid 460, and then the swinging member 464 is moved toward the side edge of the lid member 428. There will be sliding contact along the line. Therefore, there is no possibility that the swinging member 464 protruding into the storage section 400 will be damaged by the insertion operation of the receive magazine 422.

Therefore, when the receive magazine 422 is loaded into the storage section 400, one end of the swinging member 464 is attached to the lid member 428.
The engagement member 454 is engaged with an engagement groove 454a attached to the engagement member 454. Next, when the lock release operation member 474 disposed on the side of the receive magazine loading port 20 is rotated,
Arm members 470a and 470b rotate in the direction of arrow C via a support shaft 471, and a roller member 4 is attached to the end of the arm members 470a and 470b.
72a and 472b press the ends of lock members 444a and 444b disposed on the sides of receive magazine 422. As a result, the locking members 444a, 444
b is a pin member 446a.

It rotates around 446b, and its claws 450a, 45
0b is the locking member 452a, 45 attached to the lid member 428
Leave from 2b. Therefore, the lid member 428 can be opened inside the storage section 400.

Next, when the solenoid 460 is driven to displace the movable rod 462, the swinging member 464 rotates in the direction of arrow A around the support shaft 469, and the locking member 454 is attached to one end of the swinging member 464. The lid member 428 that is engaged with the hinge 4
It will rotate around 26a to 426c.

As a result, the seat storage opening 42 of the receive magazine 422
9 is opened toward the conveyance system 402. Then,
The stimulable phosphor sheet S is stored in the storage section 424 of the receive magazine 422 through the sheet storage opening 429 .

When the stimulable phosphor sheet S is stored in the receive magazine 422, the solenoid 460 is driven again, and the movable rod 462 rotates the lid member 428 via the swinging member 464 toward the storage section 424 of the receive magazine 422. Then, the sheet storage opening 429 is closed. Therefore, the sheet storage opening 429 is opened only when storing the sheet S in the storage section 400, so that, for example, light from the barcode reading section 332 is prevented from being irradiated onto the sheet S, and the It becomes possible to suitably protect the sheet S from unnecessary external light.

After all the stimulable phosphor sheets S have been stored, the operating member 474 is rotated to rotate the arm members 470a and 470b in the direction of the arrow to retract them from the receive magazine loading port 20. Locking member 45 attached to 428
2a and 452b are locking members 444a.

The lid member 428 is locked by being engaged with the claws 450a and 450b of 444b. Therefore, the receive magazine 422 pulled out from the storage section 400 is completely shielded from light by the mold member 428, and the lock members 444a and 444b prevent the lid member 428 from opening, so that the accumulation stored therein is prevented from opening. There is no danger that the phosphor sheet S will be exposed to external light.

The receive magazine 422 containing the stimulable phosphor sheets S in this state is loaded into an image reading device (not shown), the sheets S are taken out one by one, and the image information recorded on the sheets S is read out photoelectrically. The image information is output as a visible image by an image reproducing device such as a laser printer or CRT.

As described above, according to the present invention, the locking state of the lid member of the magazine that accommodates the image recording carrier in a light-tight state is released from the magazine under the biasing action of the locking release means, and the cover member is opened/closed. The storage opening for the image recording carrier is opened by the four substages. Therefore, the image recording carrier storage opening of the magazine, which is maintained in a light-tight state in a bright room, can be opened and closed as necessary.
There is no possibility that the image recording carrier stored in the magazine will be irradiated with unnecessary external light. As a result, there is no need to provide a light shielding means on the target device in which the magazine opening/closing mechanism according to the present invention is incorporated, and a magazine opening/closing mechanism can be obtained that can be configured extremely simply and manufactured at low cost.

Although the present invention has been described above with reference to preferred embodiments, the present invention is not limited to these embodiments.
It can be applied to an image capturing device using ordinary X-ray film, and various improvements and designs can be made without departing from the gist of the present invention, such as using a cylinder instead of a solenoid to displace the movable lid. Of course, it is possible to change.
