Based on the difference in shape between a mount and a dummy mount subjected to scanning, an output signal having a pattern which differs depending on whether the mount or the dummy mount is transported is outputted from a photo coupler 54 along with driving of a mount pusher pawl 23. Further, a detection signal indicative of whether the mount or the dummy mount is transported or neither the mount nor the dummy mount is transported following the driving of the mount pusher pawl 23 is outputted from a photo coupler 59. With the use of these two output signals, whether the mount is transported or not, whether the dummy mount is transported or not or whether neither the mount nor the mount is transported or not can be detected by the driving of the mount pusher pawl with high accuracy. <IMAGE> |
