Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a film loading device, and more particularly to a film loading device configured to be able to load a film package containing a plurality of sheet films into an image recording device or the like in a bright room.

2. Description of the Related Art Generally, radiation image films obtained by photographing objects such as human bodies using X-rays are widely used in medical diagnosis and the like. Conventionally, when taking radiographic images using such an X-ray film, the X-ray film is loaded into a radiation imaging device in a light-shielded state, and the emulsion surface of this film is directly irradiated with X-rays. The image of the subject is recorded.

Incidentally, recently, a radiation image recording and reproducing system that uses a stimulable phosphor to obtain a radiation transmitted image of a subject has been developed and is becoming widespread. 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 uses this stimulable phosphor, and once the radiation image information of the human body, etc.
Recording is performed on a sheet having a layer made of a stimulable phosphor, and the stimulable phosphor sheet is scanned with excitation light such as a laser beam to generate stimulated luminescence light. The image signal is read out to obtain an image signal, and based on this image signal, it is output as a visible image to a recording material such as a photographic light-sensitive material, a CRT, or the like.

Here, when recording an image on a recording material, an image recording device, for example, an image output laser printer device is employed. This device stores X-ray film, which is a recording material, through a magazine, etc., takes out the film one by one using a sheet-fed mechanism such as a suction cup, and then converts it into electrical signals obtained from a stimulable phosphor sheet. The device is configured to irradiate the film with a laser beam based on the image and record a predetermined image. Therefore, the film on which the new image has been recorded is conveyed into an automatic developing device, undergoes a developing process, and then is stored at a predetermined location and used for medical diagnosis, etc., if necessary.

Incidentally, in the image output laser printer device, when loading an X-ray film into the device, the film must not be irradiated with external light, similar to the conventional radiation image capturing device described above.

This is because it will be exposed to light. Therefore, the film loading operation is generally performed in a darkroom, but the efficiency of the loading operation is naturally low. Then, in order to improve the workability, loading the film in a normal bright room became strongly desired.
A technical idea for making this possible is disclosed in, for example, Japanese Utility Model Application Publication No. 56-7931.

That is, in relation to the prior art, FIG. 1a shows a cross-sectional view of a magazine 1 loaded into an X-ray imaging apparatus, etc., and this magazine 1 has a main body 2 and a butterfly that can be opened and closed in the main body 2. The main body 2 and the lid 3 define a chamber 4. Holding rollers 5a and 5b are rotatably supported on the main body portion 2 and the lid portion 3, respectively, and are designed to prevent external light from being irradiated into the chamber 4 from the side of the holding rollers 5a and 5b. A light shielding member 6 is provided on the main body portion 2 and the lid portion 3. Further, an opening 7 for taking out a film is formed in the lid 3, and a bent handle 9 is formed at one end of a shutter member 8 provided in the lid 3 for opening and closing the opening 7. ing.

A film package 10 is stored within this magazine 1. Inside the film packaging body 10 is a cover paper 1.
A plurality of unexposed films 1 protected by 1
2 is housed in the magazine 1, and both ends 10a and 10b of the film package 10 are exposed to the outside from the magazine 1.

In such a configuration, first, one end portion 10a of the film package 10 is engaged with the handle 9 of the shutter member 8,
The other end 10b is cut with scissors or the like. Next, as shown in FIG. 1, the magazine 1 is loaded into the X-ray imaging device 13, and the shutter member 8 is pulled out from the magazine 1 by manual operation. As a result, the film package 1
0 is attached to the handle 9 and pulled out from the magazine 1, and the film package 1o is held by the pinching rollers 5a, 5.
The unexposed film 12 in the film package 10 is fed into the chamber 4 to be sandwiched by the film package 10. moreover,
In this case, the chamber 4 in the magazine 1 is opened into the device 13 via the opening 7 . Thereupon, the unexposed film 12 is sucked by the suction cup 14 and conveyed to a predetermined photographing position.

Further, as another prior art, there is a device disclosed in Utility Model No. 56-5141. That is, FIG. 2a shows a cross-sectional view of a film package 15 to be supplied to an X-ray imaging device, etc., and this film package 15 includes a light-shielding container 17 which is a housing having an opening 16. A plurality of unexposed films 19 are stored in the light-shielding container 17 while being protected by cover sheets 18 . Further, a flexible member 20 is adhered to the opening 16 in a light-tight manner to protect the unexposed film 19 from external light. In this case, before.

One end of the flexible light-shielding member 20 is curved vertically upward, and a locking hole 20a is bored in this one end edge.

The film package 15 constructed in this way is stored in a magazine 21 shown in FIG. 2 and positioned by a storage section 22. Here, the magazine 21 is provided with a shutter member 23, and after the hole 20a of the flexible light shielding member 20 is engaged with the engagement protrusion 24 implanted at one end of the shutter member 23, , the magazine 21 is loaded into an X-ray imaging device or the like (not shown). Next, the other end of the shutter member 23 is pulled out of the magazine 21 by hand or the like.

As a result, the flexible light-shielding member 2o is peeled off from the light-shielding container 17 by the locking protrusion 24 that engages with the hole 20a, and the opening 16 is opened inside the X-ray imaging apparatus or the like.

Then, the unexposed film 19 is sucked by the vacuum suction device 25 and conveyed to a predetermined photographing position.

However, in these prior art techniques, a dedicated magazine must be used to store the film package. Since this dedicated magazine is repeatedly attached to and removed from the image recording apparatus, it needs to be manufactured strongly so that it can withstand long-term use, and as a result, the dedicated magazine itself has a considerable weight. Therefore, a drawback arises in that it is troublesome for the operator to attach and detach the dedicated magazine. Moreover, since the dedicated magazine is provided with a shutter mechanism, clamping rollers, etc., this dedicated magazine inevitably becomes expensive.

In addition, in order to load the film into the apparatus, after storing the film package in a magazine, one end of the film package is cut off, the other end is hooked to a shutter member, and the magazine is opened. It is necessary to attach the shutter member to the device and pull out the shutter member. As a result, the disadvantage is that the loading operation of such a film is complicated and takes a considerable amount of time.

The present invention has been made in order to overcome the above-mentioned disadvantages, and a package containing a plurality of films and whose film ejection opening is closed with a flexible cover member is set on a mounting base, and the package is covered with a lid. By configuring the body to sandwich the end of the cover member and open the film ejection opening while holding the package in a light-tight manner, the dedicated magazine used conventionally is not required. It is an object of the present invention to provide a film loading device which has a simple structure, allows loading of a film in a bright room very easily and in a light-tight state.

In order to achieve the above object, the present invention provides a film loading device for loading a film package in which a plurality of sheet films are stacked and stored and a film ejection opening of the film package is closed with a cover member. a mounting base on which the film package is mounted, a lid portion that closes the loading opening of the film package with one end of the cover member constituting the film package exposed to the outside of the device, and the lid portion and/or Alternatively, it is characterized by comprising a light shielding means that cooperates with the film package to keep the opened film package light-tight.

Next, preferred embodiments of the film loading device according to the present invention will be described in detail below with reference to the accompanying drawings.

3 and 4, reference numeral 30 indicates a film loading device according to the present invention, and this film loading device 3
0 constitutes, for example, a sheet film supply section in an image recording apparatus. In this case, the film loading device 3
0 basically comprises a main body part 32 on the side of the image recording apparatus and a lid part 36 which is pivotally attached to the main body part 32 and opens and closes the loading opening 34 of the film package 38.

Here, the film packaging body 38, as shown in FIG.
It is comprised of a light-shielding container 40 that accommodates a plurality of sheet-like films 1 and F in a stacked state, and a flexible cover member 44 that closes the film removal opening 42 in the light-shielding container 40.

A portion of the peripheral edge of the film take-out opening 42 in the light-shielding container 40 bulges outward to form a protruding end 46 .

Furthermore, a protrusion 48 is formed on the side surface of the light-shielding container 40 on which the protrusion end 46 is formed, and protrudes by approximately the same length as the protrusion end 46 . On the other hand, an engaging portion 50 is formed at the peripheral edge of the film take-out opening 42 facing the protruding end portion 46, and the engaging portion 50 bulges outward and has a substantially columnar tip. in this case,
Cover member 4 adhered to the film removal opening 42
4 has a length a little more than twice the length of the light-shielding container 40, and is bent at the protruding end 46 side so that the end 44a thereof extends toward the engaging part 50 side.

Therefore, the lower end portion of the lid portion 36 is pivotally attached to the main body portion 32 via the hinge member 52 in a freely rotatable state.

Mounting stands 54a and 54b, which are mounting stands for the film package 38, are attached to the lower end and upper end sides of the lid body part 36. In this case, the pedestals 54a and 54b are arranged so that the opening 42 for taking out the film 1 and the package 38 is oriented diagonally to one side when the loading port 34 is closed. The light-shielding container 40 is provided on the lower end side of the lid portion 36.
An engaging member 56 is formed that supports the protruding end portion 46 and has a hole 56a into which the protruding portion 48 fits. Here, on the main body part 32 side, when the loading port 34 is closed,
A switch 51 is provided which is operated by the protruding end 46 and detects that the package 38 is loaded. Note that the means for detecting the package 38 is not limited to a beam switch, and an optical sensor or the like may be used. Further, an upper end portion 55 of the lid body portion 36 is bent toward the main body portion 32 side, and this upper end portion 55 is close to an end portion 57 that protrudes from the main body portion 32 when the loading port 34 is closed.

On the other hand, a roller 5 is provided near the end portion 57 on the main body portion 32 side.
8 is arranged in a freely rotatable state. In this case, roller 5
8 is a film F along with the engaging portion 50 of the light-shielding container 40.
This achieves the light-shielding function of Further, a shack member 60 is disposed on the main body 32 side, and a bent thin plate-shaped shack 62 is engaged with the tip of the shutter member 60. The shutter 62 is for opening and closing a film transport port 64 defined on the main body 32 side,
A suction cup 66 that constitutes a suction mechanism for conveying the film F to the next stage image recording section enters the film conveyance port 64.

The film loading device of this embodiment is basically constructed as described above, and its operation and effects will be explained next.

First, the lid body part 36 is rotated around the hinge member 52,
The loading port 34 is opened as shown in FIG. Next, the film package 38 is attached to the lid part 36. in this case,
The light-shielding container 40 is brought into contact with the pedestals 54a and 54b, and
The protrusion 48 of the light-shielding container 40 is inserted into the hole 5 of the engagement member 56.
6a. As a result, the protruding end 46 side of the film package 38 is engaged by the engaging member 56, and the film package 38 is attached to the lid part 36 in an inclined state. Here, the end portion 44a of the cover member 44 that closes the film removal opening 42 of the light-shielding container 40 is taken out to the outside of the lid body portion 36 via the engaging portion 50 of the light-shielding container 40.

Lid body part 3 with film packaging body 38 attached in this way
6 rotates around the hinge member 52, and the loading port 34 is closed. In this case, the end 44a side of the cover member 44 is held between the engagement part 50 of the light-shielding container 40 and the roller 58 pivoted on the main body part 32 side, and the end 44a
an end 57 on the main body 32 side and an upper end 55 of the lid 36;
The film is led out to the outside of the film loading device from between. That is, the interior of the film loading device 30 is shielded from light by the lid 36, and each time the cover member 44 is held between the engaging portion 50 and the roller 58, the light shielding state is further increased and the light density is increased.

On the other hand, the protruding end 46 of the film package 38 loaded in the film loading device 30 activates the limiter 51 disposed on the main body 32 side. As a result, it is detected that the film package 38 is loaded into the film loading device 30, and there is no possibility that the loading port 34 will be opened inadvertently and the film F will be exposed.

Next, by grasping the end portion 44a of the cover member 44 and pulling it out in the direction of the arrow, the cover member 44 will be attached to the engaging portion 5.
The film is peeled off from the film removal opening 42 of the light-shielding container 40 while being held between the film 0 and the roller 58 . In this case, since the protrusion 48 formed at the end of the light-shielding container 40 is engaged with the engagement member 56 of the lid body 36, the corresponding end of the light-shielding container 40 is removed during the peeling operation of the cover member 44. Therefore, the cover member 44
Peeling work is performed well.

Further, the cover member 44 is attached to the light-shielding container 4 over a predetermined length.
When the shutter member 60 is pulled out in the direction of the arrow after peeling from the film 0, the shutter 62 is displaced, and as a result, the film ejection opening 42 of the film package 38 is directed toward the film transport port 64 of the film loading device 30. It will be opened to the public. Next, the suction cup 66 is driven to close the light-shielding container 4.
After the films F stored in the film F are sequentially fed to a transport mechanism (not shown), an image is recorded on the film F in an image recording section.

Here, it is sufficient that the opening amount of the film take-out opening 42 corresponds to the film transport port 64, and opening more than that is rather wasteful. Therefore, for example, a rod-shaped member 45 is brought into contact with the intermediate portion of the cover member 44 as shown by the broken line in FIG. By configuring the system in such a way that it is possible to prevent unnecessary work as described above.

FIG. 6 shows another embodiment of the film loading device according to the present invention. The film loading device 68 basically comprises a main body 70 in the image recording apparatus, a storage section 74 for storing the film 1, and a package 72, and a lid section 78 for opening and closing the loading lower roller in the storage section 74. Here, the film packaging body 72 is placed in the light-shielding container 79.

On the other hand, one end of the lid body 78 is rotatably attached to the end of the loading lower arm, and a locking member 98 that is engaged with the main body 70 when the loading lower arm is closed is disposed at the other end. will be established. In this case, it is preferable to form an engagement groove 78a extending in the longitudinal direction of the lid portion 78 so that light tightness is ensured when the cover member 82 is held. Further, the main body portion 7o has a shutter member 100 and a roller 102 which is pivotally attached to the end of the loading lower roller, as in the case of the embodiment described above. In this case, a shutter 104 is attached to the tip of the shutter part JfA' 100.

Therefore, the film packaging body 7 is loaded into the film loading device 68.
2, first rotate the lid part 78 to open the loading lower door and place the film package 7 in the storage part 74.
Insert 2. In this case, the cover member 82 is
2a side to the storage section 74 via the engagement section 86 of the light-shielding container 79.
Let it be derived outside of.

The film package 72 inserted into the storage section 74 is placed on the pedestal 8
The protruding end 84 formed at one end of the protruding end 84 is pressed by a pressing member 94 and engaged with the retaining part 90 . Here, since the protruding end portion 84 presses the limit switch 96 disposed on the engaging portion 94, it is detected that the film package 72 is stored in the film loading device 68. On the other hand, the end 82a side of the cover member 82 of the film package 72 is held between the engaging part 86 and the roller 102 on the main body part 70 side.

As a result, the interior of the film loading device 68 is maintained in a light-tight state by the engaging portion 86 and the roller 102.

Next, the loading lower door is closed by rotating the lid portion 78 and engaging the locking member 98 with the main body portion 70 side. At that time, the end portion 82a of the cover member 82
8 and the main body 70 to the outside. In this case, the film package 72 is isolated from the outside world by the lid 78 and is in a light-tight state.

Therefore, by grasping the end portion 82a of the cover member 82 and pulling it out in the direction of the arrow, the cover member 82 is peeled off from the light-shielding container 79. In this case, since the protruding end portion 84 of the film package 72 is held between the pressing members 94 of the engaging portion 90, the film package 72 does not move when the cover member 82 is peeled off, and the peeling operation is easy. It becomes easier.

Next, by pulling out the shutter member 100 in the direction of the arrow, the shutter 104 is displaced, and the film package 7
0 opening 80 opens into the main body 70 . Then, by driving the suction cup 106, the film F is fed to a transport mechanism (not shown).
