ABSTRACT:
When a film cartridge storing a developed film including a magnetic layer is mounted in an electronic viewer, the film is pulled out from the cartridge, and a forward end of the film is wound around a winding axis. A film transport is controlled in accordance with a detection signal generated by a frame detector every detection of the frame, so that a film image of the film can be observed. At the same time, the viewer reads out magnetic information recorded in the magnetic layer, which corresponds to each film image. Contents of the magnetic information are displayed on an LCD of the viewer. As a result, a user can observe his desirable film image and the contents of the magnetic information corresponding the desired film image.
