Abstract
The camera of the present invention is adapted to use a cartridge of a type in which when a film spool rotates in the forward direction to push the film out from the cartridge and in the backward direction to rewind the film into the cartridge. The cartridge is equipped with a bar code rotating as a whole with the film spool. The camera comprises a photoelectric reading device reading out the bar code and output the bar code signal, a decoder deciphering the bar code signal, and a microcomputer controling the circuit or the device so as to read out the bar code during film forward process, to decipher the bar code signal thus read out, to judege as to whether decipherment proves impossible to decipher the bar code signal, and to rewind the film when decipherment proves impossible to decipher the bar code signal.
