Abstract
A film reading apparatus includes a reading unit for reading a bit string magnetically recorded on a loaded film, a bit string information recording unit for recording the bit string read by the reading unit, and a collation unit for collating the bit string read by the reading unit with the bit string recorded in the bit string information recording unit. An identical film determination unit determines that the same film as the previously loaded film is loaded, in a case that the collation result obtained by the collation units indicates that the bit strings coincide with each other. The loaded film can automatically return to the previously loaded state.
