Patent ID: 6839848

Claim:
A manipulation apparatus for use with an information processing apparatus, wherein said information processing apparatus comprises a first interface means to which said manipulation apparatus is detachably connectable and a second interface means to which a recording medium is detachably mountable and is constructed so as to execute a program read from the recording medium in response to an instruction that is transmitted from and indicative of a manipulative operation on, the manipulation apparatus, said manipulation apparatus comprising: an input/output interface detachably connectable to said information processing apparatus; a manipulative input means which transmits data indicative of said manipulative operation in response to the manipulative operation on the manipulation apparatus to the information processing apparatus; read-only memory means inerasably stored with a first security code; and a control means comprising: comparison means which compares the first security code with a second security code, said second security code being read from said recording medium into said information processing apparatus and supplied from said information processing apparatus to the manipulation apparatus; and operation control means which transmits confirmation data to the information processing apparatus when the codes coincide with each other, and which stops the operation of the manipulation apparatus or transmits to said information processing apparatus an instruction in response to which said information processing apparatus stops the execution of the program read from the recording medium when said first security code and said second security code do not coincide with each other, whereby a judgment is made as to whether said recording medium is authentic with respect to the manipulation apparatus.
