Abstract
There is disclosed a main unit as an identifying apparatus for outputting an identification code and subjecting the identification code to encode by an encoding section to obtain a specific code. A process unit as an apparatus to be identifying subjects the identification code outputted from the main unit to the encoding by an encoding section by the same logic as that of the encoding section to obtain a response code, and returns the response code to an input port of the main unit. In the main unit, a collating section collates the specific code obtained by the encoding section and the signal inputted to the input port, and CPU judges the attached process unit to be original when a collation result indicates coincidence.
Claims33
An identifying apparatus, to which a separate apparatus to be identified can arbitrarily be attached, for identifying whether an original apparatus is attached, the identifying apparatus comprising:
- an input port which receives an input signal from the separate apparatus, the input signal having a code which changes in accordance with a predetermined pattern;
- a collating section which collates whether or not a change pattern of the code in the input signal provided to the input port coincides with a predetermined change pattern;
- and
- an identifying section which identifies attachment of the original apparatus only when coincidence is judged by collation by the collating section.
An identifying apparatus, to which a separate apparatus to be identified can arbitrarily be attached, for identifying whether an original apparatus is attached, the identifying apparatus comprising:
- an input port which receives an input signal from the separate apparatus;
- an output port which supplies an output signal to the separate apparatus;
- a code generating section which outputs a predetermined identification code through the output port to the separate apparatus;
- an encoding section which encodes the predetermined identification code generated by the code generating section to a specific code according to a predetermined rule;
- a collating section which collates whether or not the specific code obtained by the encoding section coincides with the input signal provided to the input port;
- and
- an identifying section which identifies attachment of an original apparatus only when coincidence is judged by collation by the collating section.
An apparatus to be identified which enables an identifying apparatus to identify attachment of an original apparatus, when the apparatus to be identified is attached to the identifying apparatus comprising:
- an input port which receives an input signal from the apparatus to be identified;
- a collating section which collates whether or not a change pattern of a code in an input signal from the input port coincides with a predetermined change pattern;
- and
- an identifying section which identifies attachment of the original apparatus only when coincidence is judged by collation by the collating section,
- wherein the apparatus to be identified comprises:
- a response signal generating section which supplies a response signal which arranges different codes in the predetermined change pattern every time to the input port.
An apparatus to be identified which enables an identifying apparatus to identify attachment of an original apparatus, when the apparatus to be identified is attached to the identifying apparatus comprising:
- an input port which receives an input signal from the apparatus to be identified;
- an output port which supplies an output signal to the apparatus to be identified;
- a code generating section which outputs a predetermined identification code through the output port;
- an encoding section which encodes the identification code generated by the code generating section to a specific code according to a predetermined rule;
- a collating section which collates whether or not the specific code obtained by the encoding section coincides with the input signal from the input port;
- and
- an identifying section which identifies attachment of the original apparatus only when coincidence is judged by collation by the collating section,
- wherein the apparatus to be identified comprises:
- a response code generating section which supplies a response code obtained by encoding the identification code output through the output port of the identifying apparatus according to the same rule as that of the encoding section to the input port.
An identifying method for identifying attachment of an original apparatus to be identified in an identifying apparatus to which a separate apparatus to be identified can arbitrarily be attached and which comprises an input port which receives a signal from the apparatus to be identified, the method comprising the steps of:
- receiving an input signal from the separate apparatus, the input signal having a code which changes in accordance with a predetermined pattern;
- collating whether or not the change pattern of the code in the input signal from the input port coincides with the predetermined change pattern;
- and
- identifying the attachment of the original apparatus to be identified only when coincidence is judged.
An identifying method for identifying attachment of an original apparatus to be identified in an identifying apparatus to which a separate apparatus to be identified can arbitrarily be attached and which comprises an input port which receives a signal from the apparatus to be identified and an output port which supplies an output signal to the apparatus to be identified, the method comprising the steps of:
- outputting a predetermined identification code through the output port;
- encoding the identification code to a specific code according to a predetermined rule;
- collating whether or not the specific code coincides with the input signal from the input port;
- and
- identifying attachment of the original apparatus to be identified only when coincidence is judged.
