PURPOSE:To accurately and surely carry film in and out of a film holder. CONSTITUTION:This X-ray quick photographing device 1 is provided with the film holder 6 which moves back and forth between a photographing standby position and a photographing position, inside which the film 2 is housed and which is freely opened/closed; and carrying in/out rollers for carrying the film 2 and out of the film holder 6 at the photographing standby position and constituted of a driving roller 33 and a driven roller 34 In the device 1, the carrying in/out rollers are disposed on both sides of the film 2, the driven rollers 34 on both sides are fixed on the same driven shaft 36, and the film holding and retreating actions of the shaft 36 and the opening/closing actions of the film holder 6 are synchronously performed by separate levers 43(23) engaged with cams 46(60) separately fixed on the same rotary shaft 45. By disposing the carrying in/out rollers on both sides of the film 2, the carrying force for the film becomes strong. The opening/closing of the film holder 6 and the movement of the driven shaft 36 for the carrying in/out rollers are controlled by the movement of the same rotary shaft 45, whereby the accurate operation is performed. |
