Description

[Detailed Description of the Invention] -Technical Field- The present invention relates to an apparatus for photographing an image displayed on a cathode ray tube on a photosensitive sheet in, for example, a computer tomography tomography apparatus.

-Prior Art- Conventionally, this type of image photographing device has been proposed by the present applicant in Japanese Patent Application No. 133915/1983. That is, in this image capturing device, the entire photosensitive sheet (X-ray film) taken out from a supply magazine located in front of the machine is pulled out by an inclined transfer belt, and then reversed by reversing the transfer belt. The photosensitive sheet is sent to an exposure stage, and the photosensitive sheet after image exposure is collected by a vertical collection belt into a collection magazine located at an inclined position. Therefore, in an image capturing device with this structure, the supply magazine and the recovery magazine can be located at the front of the machine, making it possible to obtain a compact and relatively easy-to-use device. Since the retrieval belt is used in the same direction, the height of the machine tends to be high, and the direction in which the retrieval magazine is installed is extremely upward, so there is room for improvement in terms of usability.

-Purpose and structure- In view of the actual situation of conventional image capturing devices as described above, the present invention aims to enable the supply magazine and the collection magazine to be handled at hand and to reduce the height of the machine. In an image capturing device, a photosensitive sheet such as an X-ray film is fed from the side to an exposure stage located above the in-flight image, and the exposed photosensitive sheet is sent in the return direction and taken out from the exposure stage. The supply path is composed of a group of reversible rollers, and a take-out belt device having an endless stretchable belt is arranged below the feed path, and the upper movable shaft of the take-out belt device is connected to the It is proposed that the photosensitive sheet be retracted below the supply path and intervened on the supply path when the photosensitive sheet is taken out.

-Embodiments- Hereinafter, details of embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is an overall cross-sectional view of an image photographing apparatus according to the present invention, in which a cathode ray tube 2 and a projection lens 3, which can display an output image of a computer tomography tomography apparatus, are housed inside a body 1. Although not shown, the cathode ray tube 2 and the projection lens 3
The assembly consisting of the following is movable within a horizontal plane perpendicular to the plane of the drawing of FIG. 1 in order to take time-lapse pictures of the photosensitive sheet a, and is moved to a position depending on the purpose of taking pictures and then kept stationary. Above the projection lens 3 is an exposure stage 5 composed of horizontal suction plates 4A and 4B.
A movable arm 7 supported by the body 1 by a base shaft 6 and capable of raising and lowering is located at the lower part of one side of the exposure stage 5, and the movable arm 7 has guide plates 8A and 8B. and is supported by guide rollers 9. The movable arm 7 is placed in the position shown by the imaginary line when the photosensitive sheet a is fed or discharged as will be described later, and therefore, the movable arm 7 is placed in the position shown by the imaginary line when the photosensitive sheet a is fed or discharged. A passage for the photosensitive sheet a is formed in between. Also,
When taking an image with the cathode ray tube 2, the movable arm 7 is brought down to the position shown by the solid line and retreated out of the screen of the photographing lens 3. In this case, the photosensitive sheet a acts on the vacuum pressure boxes 10A and 10B. The vacuum pressure applied thereto attracts and holds them onto the surfaces of the suction plates 4A and 4B.

Photosensitive sheets a in a supply magazine 12 mounted on a supply stand 11 on the upper side of the machine body 1 are taken out one by one into a supply path 14 by a vacuum suction head 13. The supply path 14 formed horizontally adjacent to the suction plates 4A, 4B is constituted by a plurality of pairs of reversible roller groups 15A, 15B,
A reversible feed roller 16 is positioned between the suction plates 4A and 4B in the same horizontal plane as these plates, and the rotation of this feed roller 16 simultaneously takes in the photosensitive sheet a to the exposure stage 5. Perform removal from stage 5.

Further, an inclined take-out belt device 17 is located below the supply path 14.
7, the exposed photosensitive sheet a is collected into a collection magazine 18 located below the supply magazine 12. That is, the take-out belt device 17 has a stretchable endless belt 21 stretched between a drive roller 19 and a driven roller 20, and the drive roller 19 has an auxiliary roller 22 facing the intake port 18a of the collection magazine 18. are connected. The upper movable shaft 23 supporting the driven roller 20 can be moved up and down by an electromagnetic solenoid or other up and down movement mechanism (not shown), and is able to move up and down from the supply magazine 12 to the exposure stage 5.
When the photosensitive sheet a is fed toward
When the exposed photosensitive sheet a is collected into the collection magazine 18, the upper movable shaft 23 is placed in the raised position shown in the second figure, the driven roller 20 is intervened in the supply path 14, and the endless belt 21 moves in the direction of the arrow. driven in the direction.

Note that the paper ejection roller 24 located on the right side of the exposure stage 5 is used when an automatic developing device is coupled to the illustrated image photographing device;
With this function, the photosensitive sheet a can be taken out from the discharge port 25. In the illustrated embodiment, if a paper feeding abnormality such as two-sheet feeding occurs during the paper feeding operation by the vacuum suction head 13, or if an emergency situation occurs,
By setting the driven roller 20 to the position shown in FIG. 2 and rotating the driving roller 19 in the reverse direction, the photosensitive sheet a can be collected into the collection magazine 18 without being supplied to the exposure stage 5.

Since the illustrated embodiment has the above structure,
Photosensitive sheet a taken out from supply magazine 12
is sent in the direction of the arrow in FIG. 1 by the normal rotation of the roller groups 15A, 15B, and is sent to the passage between the suction plates 4A, 4B of the exposure stage 5 and the guide plates 8A, 8B, and is stopped. When exposing the photosensitive sheet a, vacuum pressure is applied to the vacuum pressure boxes 10A and 10B,
The photosensitive sheet a is suctioned and held by the suction plates 4A and 4B, the movable arm 7 is brought down to the position shown by the solid line in FIG. The photosensitive sheet a is exposed to light. After exposure, the movable arm 7 is returned to the position shown in FIG. 2, the driven roller 20 of the take-out belt device 17 is inserted into the supply path 14, and the drive roller 19 and feed roller 16 of the take-out belt device 17 begin to rotate. From there, the exposed photosensitive sheet a is passed through the supply path 1 along the endless belt 21.
4 and moved into the collection magazine 18.

-Effects- As is clear from the above explanation, the present invention provides an easy-to-use structure that allows the supply magazine and the recovery magazine to be handled at hand, and has the advantage of reducing the height of the aircraft. There is.
