Abstract
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.
Claims6
A mount carrier unit comprising:
- a transport means which sequentially transports mounts which hold films or dummy mounts which have a feature different from a feature of the mounts one after another in the order in accordance with the relative position between the mounts and the dummy mounts in the inside of a mount accommodating box in which the mounts and the dummy mounts are accommodated in a stacked manner, and
- a first sensor which is capable of outputting detection results having patterns different from each other corresponding to a case in which the mount is transported by the transport means and a case in which the dummy mount is transported by the transport means based on the features of the mount and the dummy mount along with the driving of the transport means.
A film scanner comprising:
- a scanning means for scanning images recorded in films held by mounts,
- a transport means which sequentially transports mounts or dummy mounts which have a feature in appearance different from a feature in appearance of the mounts one after another in the order in accordance with the relative position between the mounts and the dummy mounts in the inside of a mount accommodating box in which the mounts and the dummy mounts are accommodated in a stacked manner for making the mounts and the dummy mounts subjected to scanning by the scanning means, and
- a determination means for determining whether the mount or the dummy mount is transported by the transport means based on the change of image signals obtained by the scanning means following the driving of the transport means.
