Film carrier and projection apparatus

摘要

A film carrier is provided with a roll carrier for supporting a roll film and a sheet carrier for supporting a sheet film, and is arranged to use either one of the carriers as selectively positioning it in a projection optical path. In the film carrier, the sheet carrier is moved to a first retracting position not to interfere with the roll carrier outside the projection optical path when the roll carrier is located on the projection optical path. In contrast, the roll carrier is moved to a second retracting position not to interfere with the sheet carrier outside the projection optical path when the sheet carrier is located on the projection optical path. The sheet carrier and the roll carrier at the first and second retracting positions are arranged so that at least parts thereof overlap vertically.
