Abstract

PURPOSE:To prevent mismanagement by comparing a discriminating code read out of a discriminating code label with a separately inputted discriminating code of a recording medium to be set and outputting an incoincidence signal when these codes do not coincide with each other. CONSTITUTION:A loanable case (reel) 1 housed with an individual recording medium is provided with the discriminating code label 11 to be filled with a discriminating code for manageably discriminating the recording medium. A code reader part 2 reads the discriminating code written in the discriminating code label 11 to output. A code input part 3 is constitutive of a key board, etc., and inputs the discriminating code of the recording medium to be set. A comparator part 4 compares the discriminating code from the code reader part 2 with the discriminating code from the code input part 3, and decides whether or not these codes are coincident, and, if not coincident, outputs the incoincidence signal. By this method, mismanagement can be prevented.
