ABSTRACT:
A reading device for reading identification information of cartridges comprises a judging circuit for judging whether the cartridge has an identification information storer for storing the identification information of a recording medium thereof, and an information reader for reading the identification information of the identification information storer. This judgment is made before the information reader reads the identification information of the identification information storer, and the information reader reads the identification information only in the event that the cartridge has an identification information storer. Accordingly, waste of time and labor are spared for reading the identification information, and trouble such as deterioration and damage from to attempting to read the identification information from storage medium cartridges which do not have the identification information storers can be prevented. Consequently, reading of identification information of the recording medium cartridges can be performed efficiently.
