も改善の余地があつた。-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.

れる。 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.
