PURPOSE:To permit quick and exact positioning of a lifting table even if a moving distance is large by driving only the 1st driving means at a high speed or driving the same together with a 2nd driving means to move the lifting table vertically at a high speed, then stopping the driving by the 1st driving means and executing driving by the 2nd driving means when the lifting table comes to the position just before a film taking out position. CONSTITUTION:An endless chain 82 moves in arrow B, C directions when a high speed motor runs counterclockwise at a high speed and a low speed motor runs clockwise at a low speed. The lifting table 14, therefore, ascends similarly at a high speed. The driving of the high speed motor is stopped and the low speed motor is driven so that the endless chain 82 moves in the arrow C direction when a 1st sensor 136 detects the bottom end of a projection. A home position sprocket 88, consequently, rotates clockwise and moving sprockets 78, 80 rotate counterclockwise, but home positions 86, 92 have the low resistance of the high speed motor and do not, therefore, rotate. The quick and exact movement of a film magazine to the film taking-out position is thereby permitted.
