Abstract:
An identifying apparatus to which an apparatus to be identified is freely replaceable, for identifying a status of the apparatus to be identified, the identifying apparatus comprising:an input port configured to receive an input signal from the apparatus to be identified; an output port configured to supply an output signal to the apparatus to be identified; an identification code generating section configured to generate an identification code and output the identification code from the output port; a plurality of encoding sections corresponding to a plurality of logics, respectively and each configured to encode the identification code into a specific code by a corresponding one of the logics; a plurality of collators corresponding to the plurality of encoding sections, respectively and each configured to collate the specific code obtained by a corresponding encoding section and the input signal received by the input port with each other; an identifying section configured to identify a status of the apparatus to be identified based on a collation result of the plurality of collators; and a logic rewriting section configured to monitor a use status of the apparatus to be identified based on an identification result of the identifying section and rewrite a logic for encoding the code in the apparatus to be identified at given timing.
