Description

The present invention relates to a film loading device, and more specifically, a film packaging body containing a plurality of sheet films is placed on a movable base that can move back and forth, and a light shielding member is attached to the film packaging body. The film packaging body is cut in a state where the film packaging body is brought into contact with each other and is shielded from light well, and when the film packaging body is pulled out, the moving base and the light shielding member are displaced relatively away from each other to facilitate the pulling-out work of the film packaging body. The present invention relates to a film loading device configured so that a sheet film can be easily loaded in an image recording device or the like in a light chamber in a light-tight state in a bright room.

In general, a radiation image film obtained by photographing an object such as a human body using X-rays is widely used for medical diagnosis and the like. Conventionally, when a radiation image is captured using such an X-ray film, the X-ray film is loaded in a radiation image capturing device in a light-shielded state, and the emulsion surface of the film is directly irradiated with the X-ray. The image of the subject is recorded.

By the way, recently, a radiation image recording / reproducing system for obtaining a radiation transmission image of a subject by using a stimulable phosphor (stimulable phosphor) has been developed and is becoming widespread. Here, as the stimulable phosphor, radiation (X-ray, α-ray, β-ray, γ-ray,
When the electron beam, the ultraviolet ray, etc.) is irradiated, a part of this radiation energy is stored, and when the excitation light such as visible light is irradiated later, stimulated emission light corresponding to the stored energy is produced.

The above-mentioned radiation image recording / reproducing system utilizes this stimulable phosphor, and once the radiation image information of the human body is
Recording on a sheet having a layer made of a stimulable phosphor, scanning the stimulable phosphor sheet with excitation light such as laser light to generate stimulated emission light, and the obtained stimulated emission light is photoelectrically converted. The image signal is read to obtain a visual image on a recording material such as a photographic light-sensitive material or a CRT based on the image signal.

Here, when an image is recorded on the recording material, an image recording device, for example, an image output laser printer device is adopted. This device stores a photographic photosensitive film, which is a recording material, through a magazine and the like, takes out the films one by one by a sheet-fed mechanism such as a suction plate, and then based on an electric signal obtained from a stimulable phosphor sheet. The film is irradiated with the modulated laser beam to record a predetermined image. Therefore, the film on which the new image is recorded is conveyed into the automatic developing device, undergoes the developing process, is stored in a predetermined place, and is used for medical diagnosis or the like as necessary.

By the way, in the image output laser printer device, when the film is loaded in the device like the above-described conventional radiation image capturing device, the film should not be exposed to external light. Because it will be exposed. Therefore, in general, when loading a film in an image recording device or the like,
The disadvantage is that it must be done in a dark room.

Therefore, in order to improve the operability, it is strongly desired to load the film in the bright room, and various bright room loading methods have been proposed to enable this. Japanese Utility Model Publication No. 56-7931 discloses an example of this bright room loading method. This is shown in Figures 1a and 1b.

That is, in relation to the prior art, FIG. 1A is a sectional view of a magazine 1 loaded in a radiographic image capturing apparatus or the like, and the magazine 1 can be opened and closed by a main body 2 and the main body 2. The main body portion 2 and the lid portion 3 define a chamber 4 including a lid portion 3 to be hinged. Clamping rollers 5a and 5b are rotatably supported by the main body 2 and the lid 3, respectively, and the outside of the chamber 4 is not irradiated from the side of the clamping rollers 5a and 5b. A light-shielding member 6 is provided on the main body 2 and the lid 3. Further, an opening 7 for taking out the film is formed in the lid portion 3, and a bending handle 9 is formed at one end of a shutter member 8 provided in the lid portion 3 for opening and closing the opening portion 7. There is.

Then, the film package 10 is stored in the magazine 1. A plurality of unexposed films 12 are stored in the film package 10 while being protected by a corrugated cardboard 11, and both ends 10a and 10b of the film package 10 are exposed from the magazine 1 to the outside. ing.

In order to load the film package 10 having the above-mentioned configuration in the light chamber, first, one end 10a of the film package 10 is engaged with the handle 9 of the shutter member 8 and the other end 10b is scissors. Etc. Then, as shown in FIG. 1b, the magazine 1 is loaded into the X-ray imaging apparatus 13,
The shutter member 8 is pulled out from the magazine 1 by manual operation. As a result, the film package 10 is attached to the handle 9 and pulled out from the magazine 1, and the film package 10 is sandwiched by the sandwiching rollers 5a and 5b, so that the unexposed film package 10 is not exposed. The film 12 remains in the chamber 4.

Further, in this case, the chamber 4 in the magazine 1 is opened through the opening 7 opened by the pulling operation of the shutter member 8.
Are opened in the device 13. Then, the unexposed film 12 is sucked by the vacuum suction device 14 and conveyed to a predetermined photographing position.

However, in the above-mentioned conventional technique, the film package 10 is housed in the magazine 1 and both ends 10a and 10b thereof are exposed to the outside, and then the shutter member 8 is inserted into the magazine 1 to cut the end 10b. Then, the magazine 1 is loaded into the device 13 and the shutter member 8 is engaged with the end 10a.
We are working together to pull it out. For this reason, the device
It is pointed out that the work of loading the unexposed film 12 into the film 13 is complicated and considerably time-consuming.

Furthermore, the operation of the shutter member 8 is performed by the operator's own fingers or the like. Therefore, it is likely that the shutter member 8 is not reliably inserted into the magazine 1. If the end portion 10b of the film package 10 is cut in such a state, outside light will enter the film package 10 from the cut portion. It is pointed out that the unexposed film 12 which is irradiated and laminated is exposed.

Another conventional technique is the device disclosed in Japanese Utility Model Publication No. 57-25220. That is, FIG. 1c shows a sectional view of a magazine 1a, which includes a main body 2a and a lid 3a hinged to one end of the main body 2a so as to be openable and closable. A chamber 4a is defined by the main body 2a and the lid 3a, and nipping rollers 5c and 5d are rotatably supported by the main body 2a and the lid 3a, respectively. Further, a film extraction opening 7a is formed in the main body 2a, and the main body 2a
The shutter member 8a mounted on the upper part of the opening
7a is opened and closed.

Therefore, when loading the film package 10 into a device (not shown) in the light chamber, first, the other end 10b of the film package 10 is cut by the scissors 15 (see FIG. 1d). Then, the other end 10b is held with a fingertip while the other end 10b is bent so that the film package 10 is not irradiated with external light.

On the other hand, in the magazine 1a, the lid portion 3a is previously opened, the film packaging body 10 is inserted into the chamber 4a from the bent end portion on the other end portion 10b side, and the one end portion 10a is inserted in the magazine 1a.
Expose to the outside of a. Further, after closing the lid portion 3a, if the one end portion 10a exposed to the outside is pulled in a direction away from the magazine 1a, the film packaging body 10 is pulled out to the outside, and the inside of the film packaging body 10 is pulled out. The unexposed film 12 remains in the chamber 4a via the nipping rollers 5c and 5d.

Then, when the magazine 1a is loaded into a device (not shown) and the shutter member 8a is manually pulled out from the magazine 1a, the film extraction opening 7a is opened in the device (not shown).

However, in the above-mentioned conventional technique, after cutting the other end 10b of the film package 10 with the scissors 15, the other end 10b is inserted into the chamber 4a of the magazine 1a in a state where the other end 10b is blocked and held by the operator's fingertip. Then, the lid 3a is closed and the one end 10a exposed to the outside is pulled to take out the film package 10 from the magazine 1a. Next, the magazine 1a is loaded into the apparatus and the shutter member 8a is operated to open the film extraction opening 7a in the apparatus.

Therefore, it is pointed out that the work of loading the unexposed film 12 into the apparatus is considerably complicated as in the prior art shown in FIGS. 1A and 1B.

Moreover, the worker holds the cut other end 10b with his fingertip and loads the film package 10 into the chamber 4a from one end of the main body 2a. Therefore, it becomes difficult to completely shield the unexposed film 12 from the outside, and in particular, the operator releases his / her fingertip from the other end 10b to insert the cut other end 10b into the magazine 1a. It is pointed out that the other end 10b may irradiate the inside of the film package 10 with external light when performing the process.

The present invention has been made in order to overcome the above-mentioned inconveniences, and provides a movable base that can be moved forward and backward for mounting a package containing a plurality of films, and a light-shielding member that comes into contact with the package. Then, when cutting the end of the package, the light shielding member is pressed against the package to prevent the external light from being radiated from the cut end, and when the package is further pulled out, the movable table and the light shield are used. Provided is a film loading device that is configured to perform a pulling-out operation of the package favorably by displacing the member away from each other, thereby allowing the film to be held in a light-tight manner and easily and surely loading the film in a bright room. The purpose is to do.

In this case, both longitudinal end portions 118a and 118b of the film package 116 are sealed by welding or the like, the both end portions 118a and 118b are folded back to the take-out surface side of the sheet film F, and then integrally formed via a seal 120. I'm locked up. In addition, in FIG. 2, the portion indicated by the broken line indicates the cut portion 122 of the film package 116.

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

As shown in FIG. 3A, when the mounting table 34 is pulled out from the main body portion 30, the rod body 80 constituting the pulling means 78 is separated from the wall surface portion 102, and the rod body 80 is pulled by the pulling force of the spring 86. It is pulled in the direction of arrow A with respect to the mounting table 34. Therefore, the rod 80
The projection 82 formed on the engaging portion engages with the locking portion 76 of the moving base 66 and pulls it in the direction of arrow A. Therefore, the movable table 66 is displaced in the direction of arrow A through the pulling force of the spring 86 and the spring 68 attached to the movable table 66, and the end thereof is brought into contact with the light shielding member 58 of the locking means 56.

Then, as shown in FIG. 2, the film wrapping body 116 is loaded on the moving table 66 in the mounting table 34. In this case, the light blocking member 58
If the distance between the roller 72 and the roller 72 is selected to be slightly smaller than the length in the longitudinal direction of the film package 116, when the film package 116 is accommodated in the moving table 66, the film package 116 is moved by the moving table. It will be firmly fixed to 66.

Then, the cutter member 92 housed in the opening 94 of the mounting table 34 is taken out, the cutter member 92 is moved along the lateral direction of the film package 116, and a cutting portion of the film package 116 indicated by a broken line is shown. Cut 122.

In this way, after the film package 116 is cut at a desired portion, the cutter member 92 is arranged again in the opening 94, and the end 118b side of the film package 116 is cut into the cut end 118a. It is folded back to the handle 44 side integrally with the remaining portion, and the mounting table 34 is displaced to the main body 30 side. Therefore, the flange portion 84 of the rod body 80 constituting the pulling means 78 abuts the wall surface portion 102 of the main body portion 30, and the rod body 80 is fixed by the spring 86.
It moves in the direction of arrow B with respect to the mounting table 34 against the tensile force of. As a result, the protrusion 82 of the rod body 80 is separated from the locking portion 76 of the movable table 66, and only the tensile force of the spring 68 acts on the movable table 66.

Therefore, the mounting table 34 is housed in the main body 30 via the guide ridges 40a, 40b and the guide grooves 42a, 42b engaging with the guide ridges 40a, 40b, and the stopper means 104 is driven. That is, as shown in FIG. 3B, the drive shaft 10 is rotated under the drive action of the rotary solenoid 106 to swing the locking member 112 in the arrow C direction. Therefore, the end portion of the locking member 112 has the mounting table 34
The mounting table 34 is fixed in the main body portion 30 by engaging with the notch portion 114 formed in the side wall portion 36d.

Further, in this case, the end portion of the film package 116 mounted on the handle 44 of the mounting table 34 is clamped by the roller 96 and the light shielding plate 46 via the elastic force of a spring (not shown), It is exposed to the outside through a gap 100 between the main body 30 and the handle 44. Therefore, if the end portion of the film package 116 exposed to the outside is pulled in the direction of arrow B, the moving base 66 on which the film package 116 is placed resists the tensile force of the spring 68 and is in the direction of arrow B. And is brought into contact with and supported by the locking plate 48.

At this time, as shown in FIG. 4, the protrusion 74 provided on the moving base 66 is displaced in the direction of the arrow B, and the rotating body 64 is moved to the protrusion 74.
The light shielding member 58 swings downward in the vertical direction about the fulcrum pin 60 to separate from the fulcrum pin 60. As a result, the light shielding member 58 is completely separated from the film package 116 by the displacement operation of the moving base 66 in the direction of the arrow B and the swinging action of the light shielding member 58. When the film package 116 is pulled out in the direction of the arrow B, the sheet films F stacked and stored in the film package 116 are left on the moving table 66 via the rollers 72 and 98, respectively.

When the film package 116 is guided by the rollers 54a to 54d and is entirely guided to the outside, the movable table 66 is displaced in the direction of arrow A through the tensile force of the spring 68, and the rotary body 64 is rotated.
Engages with the protrusion 74, and the light shielding member 58 reaches the position shown by the solid line in FIG. As a result, the end portion of the sheet film F placed on the moving table 66 contacts the light shielding member 58 and is positioned.

Next, under the driving action of the sheet-fed mechanism 115, the plurality of sheet films F stacked and placed on the moving table 66 are adsorbed one by one and conveyed to an image recording mechanism (not shown).

In this case, in the present embodiment, since the movable base 66 that can move back and forth is arranged on the mounting base 34, and the light shielding member 58 that comes into pressure contact with the end of the film package 116 mounted on the movable base 66 is provided, The sheet film F can be reliably loaded in the main body 30 in the room.

That is, when the mounting table 34 is pulled out from the main body 30,
A relatively large tensile force is applied to 66 in the direction of arrow A through a spring 68 attached to the spring 66 and a spring 86 attached to a rod 80 constituting a pulling means 78. Therefore, when the film packaging body 116 is mounted on the mounting table 34, the longitudinal ends of the film packaging body 116 are firmly sandwiched between the roller 72 and the light shielding member 58. Therefore, when the cut portion 122 of the film package 116 is cut through the cutter member 92, the cut portion 122 does not illuminate the inside of the film package 116 with external light. As a result, for example, as described above in the conventional magazine, the light-shielding defect that is likely to occur when the operator operates the shutter member is avoided, and the sheet film F is kept in a light-tight state in the film package 116. The effect that the cutting portion 122 can be cut is obtained.

On the other hand, when the mounting table 34 is housed in the main body section 30, the flange section 84 of the rod body 80 abuts the wall surface section 102, and the pulling action of the pulling means 78 on the moving stand 66 in the direction of arrow A is released. Therefore,
Only the pulling force of the spring 68 acts on the moving base 66, and if the end exposed to the outside of the film package 116 is pulled in the direction of arrow B, the moving base 66 on which the film packaging 116 is mounted is compared. It is easily displaced in the direction of arrow B with a very small tensile force. Therefore, the film package 116 is separated from the light shielding member 58, and the film package 116 can be smoothly pulled out without being locked by the light shielding member 58.

In this case, instead of the swingable light shielding member 58, a fixed light shielding member can be used.

That is, as shown in FIG. 5, directly in the mounting table 34,
A light blocking member 58a is provided upright, and an opening 59 for inserting the rod 80 is formed in the lower part of the light blocking member 58a.
Therefore, when the mounting table 34 is pulled out from the main body portion 30, the movable table 66 contacts the fixed light shielding member 58a through the pulling force of the springs 68 and 86, as in FIGS. 3A and 3B. The end of the film package 116 attached to the moving base 66 is pressed by the light shielding member 58a to ensure a suitable light shielding state. On the other hand, when the mounting table 34 is housed in the main body portion 30 and the film package 116 is pulled out, the moving table 66 is displaced integrally with the film package 116 in the direction of the arrow B to shield the light.
The film package 116 is separated from 8a. After all, the film package 116 can be smoothly pulled out without being obstructed by the light shielding member 58a.

Furthermore, another embodiment of the film loading device according to the present invention is shown in FIGS. 6a and 6b. The same components as those of the first embodiment are designated by the same reference numerals with a and detailed description thereof is omitted.

In this case, the guide means 130 is provided in the mounting table 34a. That is, the guide means 130 includes a rod body 132, and one end of the rod body 132 is a support plate body 134 that is erected on the mounting table 34a.
Held in. The other end of the rod 132 penetrates the rear wall surface of the mounting table 34a to enter the main body 30a, and a flange 136 is formed at the other end. A rack 138 is formed on the rod body 132 over a predetermined length, and the rod body 132 and the mounting table 34 are formed.
A spring 140 is installed on the rear wall surface of a.

On the other hand, the pinion 142 meshes with the rack 138. A first arm 144, which is swingably supported on the mounting table 34a, is attached to the pinion 142, and a second arm 146 that is swingably supported corresponding to the first arm 144 and the first arm 144 are provided. A prism-shaped light blocking member 148 and a pressing member 150 are integrally bridged between the arm 144 and the arm 144. In this case, the first arm 144 and the second arm 1
46 is located outside both sides of the movable table 66a, and a gap 152 is formed between the light shielding member 148 and the pressing member 150, which is relatively narrow and extends in the lateral direction of the mounting table 34a. Is made.

A stopper pin 154 is provided in the mounting table 34a, and the second arm 146 engages with the stopper pin 154 to position the light blocking member 148 and the pressing member 150. that time,
The light blocking member 148 is arranged so as to project downward in the vertical direction from the pressing member 150.

In such a structure, as shown in FIG. 6A, when the mounting table 34a is pulled out from the main body portion 30a, the rod body 132 constituting the guide means 130 is separated from the wall surface portion 102a, and the rod body 132 is moved by the spring 140. It is displaced in the direction of arrow A via the tensile force of. Therefore, the pinion 142 that meshes with the rack 138 provided on the rod body 132 rotates in the arrow E direction. Therefore, the first arm 144 attached to the pinion 142 is replaced by the second arm 14
6 swings in the direction of arrow E integrally with 6 and the respective arms 144, 14
Similarly, the light blocking member 148 bridged to 6 and the pressing member 150 swing in the arrow E direction and are positioned via the stopper pin 154.

Next, when the film package 116a is placed on the moving table 66a, a not-shown cut portion of the film package 116a reaches the position of the gap 152 between the light shielding member 148 and the pressing member 150 which form the guide means 130. . Therefore, if a cutter member (not shown) is inserted into the gap 152 and moved along the gap 152, the film package 116a is cut from a desired portion.

Rotates in the direction of arrow D, and the first arm 144 and the second arm 146 similarly swing in the direction of arrow D to be positioned.

In this way, when the mounting table 34a is housed in the main body 30a, the light blocking member 148 and the pressing member 150, which form the guide means 130, are displaced from the film package 116a. Therefore, as described above, when the end portion of the film package 116a exposed outward from the main body 30a is pulled in the direction of the arrow B, the guide means 130 is used for pulling the film package 116a. There is no interference. As a result, the film package 116a can be pulled out of the main body 30a very smoothly.

As described above, according to the present invention, the pedestal for mounting the packaging body in which a plurality of sheet films are stacked and accommodated is configured to be movable with respect to the mounting table or the magazine, and when the packaging body is cut, A light-shielding member that comes into contact with the package and shields the cut portion from light is provided. Therefore, by pressing the movable pedestal toward the light blocking member via the elastic body, it is possible to prevent external light from being irradiated from the cut portion of the package into the package while the light blocking member is closed. You can do it. Particularly, when the package is loaded in the bright room, it is possible to effectively avoid the irradiation of the external light from the cut portion of the package, and to perform the loading operation of the package very easily and reliably. Become. Furthermore, when the package is pulled out to the outside, there is an advantage that the movable pedestal and the light shielding member are relatively separated from each other so that the work of pulling out the package can be smoothly performed.

Although the present invention has been described with reference to the preferred embodiment, the present invention is not limited to this embodiment,
Needless to say, various improvements and design changes can be made without departing from the scope of the present invention, such as being applicable to a magazine that is detachably attached to the apparatus body.
