CONSTITUTION:When a supporting body 28 reaches a bottom dead point P1 by each action of an electric motor 34 and a link mechanism, a sticking surface 52 of a sticking head 44 comes into contact with a film A via an opening part 43 of a magazine 42, and after this sticking surface 52a adheres to the film 4, the motor 34 further rotates clockwise so that the head 44 is moved by the supporting body 28 in a state of holding the film A, and it is transferred up to a spot P2, whereby the film 4 is inserted into space between a pair of feed rollers 16, and transferred to an image recording part by these rollers 16. Thus, a film takeout part 14 transferring the film A to a film conveying part 18 in this way acts for its return motion of up to a setup position of the magazine 42 by the motor 34, and again repeats the takeout motion of the film A out of the opening part 43 without entailing any noise.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a film sheet feeding device, and more specifically, to an extremely simple film feeding device for taking out a plurality of sheets of film stacked and stored in a magazine one by one and transporting them to a predetermined position. The present invention also relates to a film sheet-fed device that can be constructed in a small size.

2. Description of the Related Art In general, X-ray imaging apparatuses are widely used 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. in this case,
The X-ray film is loaded into the X-ray imaging device in a light-shielded state, and the emulsion surface of the film is directly irradiated with X-rays to record an image of the subject.

By the way, recently, a radiographic image recording and reproducing system that obtains a radiographic image of a subject using a storage phosphor (stimulable phosphor) has been developed, and it has become widespread in the medical field as mentioned above. be.

Here, a storage phosphor is a material that, when irradiated with radiation (X-rays, α-rays, β-rays, T'a, electron beams, ultraviolet rays, etc.), stores a part of this radiation energy and later emits visible light. A phosphor that emits stimulated light according to the energy accumulated by irradiation with excitation light.

The radiation image recording and reproducing system described above utilizes this stimulable phosphor, in which radiation image information of a human body, etc. is recorded once on a sheet having a layer made of the stimulable phosphor, and then the stimulable phosphor sheet is is scanned with excitation light such as a laser beam to generate stimulated luminescence light, the obtained stimulated luminescence light is read photoelectrically to obtain an image signal, and based on this image signal, a recording material such as a photographic light-sensitive material, The image is output as a visible image on 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 stacks and stores photosensitive films, which are recording materials, inside a magazine, and takes out the films one by one using a film sheet feeding device configured in the device. A predetermined image is recorded by irradiating the film with laser light based on an image signal. Then, this film is transported into an automatic developing device and, after undergoing a developing process, is stored at a predetermined location or directly used for diagnosis.

In the image output laser printer device, as described above, the film stored in the magazine is taken out one by one by the film sheet feeding device and conveyed to the image recording section. In this case, conventional single-fed film devices employ a mechanism in which, for example, a suction cup operated by a vacuum suction mechanism sucks and takes out the film in the magazine, and then moves the film to a predetermined transport path. .

However, such a vacuum suction mechanism requires a vacuum pump and a control mechanism to control the vacuum pump, and moreover, the suction cups connected to such a vacuum pump are generally used as a set. Therefore, the configuration must be extremely complex and large-scale.

Moreover, since the suction cup performs an adsorption action by coming into contact with the photosensitive emulsion surface of the film, it is necessary to reliably prevent the photosensitive emulsion surface from being damaged by the suction cup.
Care must be taken when handling it. As a result, the suction force by the suction cup must always be kept constant within a predetermined range, and there is the inconvenience of having to construct a special control mechanism for this purpose.

Moreover, as a result, the conventional film sheet-fed apparatus has made the overall structure of the image output laser printer apparatus large and expensive. Furthermore, the vacuum suction mechanism used in the film sheet feeding apparatus has the drawback that it generates considerable noise during operation, significantly deteriorating the working environment.

The present invention has been made in order to overcome all of the above-mentioned disadvantages, and it is possible to take out a plurality of sheet films stacked and stored in a magazine through a pasting means without damaging the surface of the film and transfer it to a predetermined conveyance path. It is an object of the present invention to provide a film sheet feeding device that is small in size, has a simple mechanism, is inexpensive, and can effectively prevent the generation of noise.

In order to achieve the above object, the present invention is a film sheet feeding device that takes out sheet films stored in a magazine one by one and conveys them to a predetermined position. The present invention is characterized in that a means is provided, and the sheet film is taken out from the magazine in a state in which it is adhered by the adhesion means.

Next, preferred embodiments of the film sheet-fed apparatus according to the present invention will be described in detail with reference to the accompanying drawings.

In FIG. 1, as disclosed in Japanese Utility Model Publication No. 57-22177, reference numeral 10 indicates a main body of a single film feeder, and this main body 10 has a drive section 12, a film take-out section 14, and a pair of Film transport section 1 including transport rollers 16
It basically consists of 8.

The drive 12 has a set of links 20.2 with the same length.
It includes a link mechanism consisting of two parts. These links 20.2
2 is a rotating shaft 24.2 implanted in the main body 10 at a predetermined interval.
6, one end of each is rotatably supported. On the other hand, the other ends of the links 20.22 are rotatably supported by pins 30.32, respectively. In this case, the bins 30, 32 are installed on both sides of the support 28 constituting the film take-out section 14 at the same spacing as the rotating wheels 24, 26. Therefore,
These links 20, 22 are arranged in parallel with a predetermined distance apart.

Here, when the link 20.22 rotates around the rotating shaft 24.26, the rotating shaft 24 is placed in the same drawing, for example, so that the rotating shafts 24 and 26 do not contact and interfere with each other. The rotary shaft 26 is configured to be implanted in the main body 10 with the rotating shaft 26 facing toward the front in the figure.

The main body portion 10 is provided with a driving electric motor 34 for driving the link mechanism constituted by the links 20, 22. The rotating shaft 35 of this driving electric motor 34 has the rotating shaft 3
A sprocket wheel 36 is supported which rotates with the sprocket wheel 5. This sprocket wheel 36 is connected via a chain 38 to a sprocket wheel 40 which is rotatably supported on the rotating shaft 24 of the link 20 integrally with the link 20.

On the other hand, the film take-out section 14 is connected to a support body 28 that moves by links 20 and 22, and the film A stacked in a plurality of sheets in the magazine 42 is attached and taken out one by one from the film take-out opening 43 of the magazine 42. head 44. This adhering head 44 is fixed to the support 2 via a connecting member 46.

As shown in FIG. 2, the adhesion head 44 is composed of a head holder 48 and an adhesion part 52 that is removably attached to a hole 48a of the head holder 48 with a fixing screw 50. The surface of the adhesive part 52 facing the film A serves as an adhesive surface 52a, and an adhesive material is applied to this adhesive surface 52a.

The film sheet feeding apparatus according to the present invention is basically constructed as described above, and its operation and effects will be explained next.

Therefore, first, the magazine 42 that stores the film A is loaded into an image recording device (not shown). In this case, after the film A is loaded into the image recording apparatus in a light-tight state, the opening 43 of the magazine 42 is opened and released into the apparatus.

In the opening 43 of this magazine 42, there is a sticking section 52 that constitutes a sheet-fed film device disposed within the device.
The adhesive surface 52a of is facing.

Next, when the driving electric motor 34 in the main body 10 of the single film sheet feeding apparatus is driven, the sprocket wheel 36 rotates clockwise in FIG. 1. Then, the sprocket wheel 40 connected to the sprocket wheel 36 via the chain 38 rotates, and the link 20 rotates clockwise about the rotating shaft 24. At this time, as the link 20 rotates, the link 22 rotates clockwise about the rotating shaft 2G via the support 28. Therefore,
The links 20.22 rotate in parallel about the axis of rotation 24.26, causing the support 2B to move in the direction of the arrow along the dash-dotted line in FIG. In this case, the attitude of the support body 28 is always oriented in a constant direction with respect to the magazine 42 that stores the film A, regardless of the position of the links 20.22. Therefore, the adhesion head 44 fixed to the support body 28 is also set to face the magazine 42 that stores the film A at all times.

When the support body 28 reaches the bottom dead center point P1 in FIG. It contacts the film A through. In this case, since the adhesive surface 52a is substantially composed of an applied adhesive material, the film A is adhered by this adhesive material.

Here, as the adhesive material, for example, adhesive tape is used. In addition, when using a commercially available silicone-based adhesive material manufactured by Sbilich, Switzerland, known as "rPTS Dust Mat" (trade name), there is little risk of the adhesive material transferring to Film A, which is extremely suitable. .

Next, after the adhesion surface 52a of the adhesion head 44 adheres to the film A, the drive motor 34 further rotates clockwise. Therefore, the adhesion head 44 is moved along the locus shown by the dashed-dotted line by the support body 28 while holding the film A, and is transported to the point P2 shown by the dashed-two dotted line.

At this point P2, the conveyance roller 16 constituting the film sheet section 18 is waiting. Then, the end of the film A transported to the point P2 is inserted between the pair of transport rollers 16. The film A is then transported by the transport roller 16 to an image recording section (not shown).

At this time, the adhesion head 44 with the adhesion surface 52a adhered to the film A is directed in a direction substantially opposite to the direction in which the film A is transported by the transport roller 16 along the trajectory shown by the dashed line by the action of the drive motor 34. The moving operation continues wE, and the adhesive surface 52a is separated from the film A.

The film take-out part 14, which has transferred the film A to the film transport part 18 in this manner, returns to the installation position of the magazine 42 by the action of the drive motor 34, and again takes out the film from the opening 43 of the magazine 42. repeat.

Here, if the adhesive material applied to the adhesive surface 52a is removed many times, there is a possibility that the adhesiveness of the adhesive material may decrease. In such a case, the adhesive surface 52a
The adhesive part 52 having the same shape can be removed from the head holder 48 by loosening the fixing screw 50 and replaced with a new one. Of course, it is also possible to make the adhesive surface 52a new by applying a new adhesive material again.

FIG. 3 shows another embodiment of the application head 44 described above. That is, in the same figure, reference numeral 54 indicates an adhesion head, and this adhesion head 54 is fixed to the support body 28 via a connecting member 46 in the same manner as the adhesion head 44.

An L-shaped support plate 56 is provided at the end of the connecting member 46.
One surface 56a of is fixed. The other surface 56b of the support plate 56 is arranged substantially parallel to the axis of the connecting member 46,
A small winding motor 58 is attached to this surface 56b. A rotating shaft 60 of the take-up motor 58 projects from the surface 56b so as to be perpendicular to the axis of the connecting member 46, and a cylindrical take-up reel 62 is supported on the rotating shaft 60. One end of the adhesive tape 64 is wound around the take-up reel 62 .

On the other hand, a quadrangular prism-shaped supply reel 68 is attached to the rotating shaft 66, which is installed parallel to the rotating shaft 60 at the tip of the surface 56b of the support plate 56.
is rotatably supported. Then, the adhesive tape 64
The other end side is wound on this supply reel on the 6th day.

The adhesive head 54 configured in this manner is fixed to the support body 28, as in the case of the adhesive head 44 described above, and adheres the film A with the adhesive surface 64a directed toward the film A. It is transferred between the conveyance rollers 16 that constitute the leaf section 18.

Here, if the adhesive force of the adhesive surface 64a decreases, the take-up motor 58 is driven to rotate. At this time, the take-up reel 6 supported by the rotating wheel 60 of the take-up motor 58
2 rotates in the direction of the arrow, thereby supplying reel 68
is rotated around the rotation axis 66. Therefore, the adhesive tape 64 is wound onto the take-up reel 62. Therefore, if the rotational operation of the take-up motor 58 is stopped when the supply reel 68 has rotated 90 degrees, a new adhesive tape with strong adhesive strength is located on the adhesive surface 64a, and the film A is transferred. be made possible again.

Therefore, this adhesion head 54 can be used to attach film A for a long period of time.
ensure the transfer operation.

As described above, according to the present invention, a plurality of sheet films stacked and stored in a magazine are taken out one by one through the pasting means and the sheet films are transferred. Therefore, there is no need for a complicated mechanism such as a suction mechanism for sucking the film or a control mechanism for controlling the suction mechanism as in the past. Moreover, since this device can be configured extremely simply, there is extremely little risk of accidents such as breakdowns occurring. Moreover, since the film sheet-fed device according to the present invention is small and can be easily configured, for example, when the device is incorporated into an image recording device, the entire image recording device can be further miniaturized. Furthermore, since the adhesion means is used to transport the film, there is no noise generated when transporting the film.
Film can be transported silently.

Although the present invention has been described above with reference to preferred embodiments, the present invention is not limited to these embodiments.
For example, the supply reel shown in FIG. 3 may be formed into a polygonal or cylindrical shape, and the single wafer mechanism may also be a known mechanism other than the one using the links described above. Of course, various improvements and changes in design are possible without departing from the gist of the invention.
