Abstract
An information processing apparatus includes a code transmitter unit and a code receiver unit. The code transmitter unit includes a memory for storing a code string, a trigger generator for generating a trigger signal, a generation section for generating an identification code string by reading out the code string in response to the trigger signal generated by the trigger generator, and a transmitter for transmitting the identification code string generated by the generation section. The code receiver unit includes a receiver for receiving a signal, and an extraction section for extracting the identification code string from the signal received by the receiver, and storing the extracted identification code string.
Claims12
An information processing system comprising:
- an information input unit for inputting information;
- and
- an information processing unit for processing the information input by said information input unit,
- wherein said information input unit comprises:
- memory means for storing a pass code assigned to said information input unit;
- trigger generation means for generating a trigger signal;
- timer means for measuring an elapse of a predetermined period of time;
- and
- transmission means for transmitting the pass code to said information processing unit in response to the trigger signal generated by said trigger generation means,
- wherein said trigger generation means generates the trigger signal at a time interval not less than the predetermined period of time measured by said timer means.
An information input apparatus which inputs information and sends the input information to an information processing apparatus for processing the input information, said information input apparatus comprising:
- memory means for storing a pass code assigned to said information input apparatus;
- trigger generation means for generating a trigger signal;
- timer means for measuring an elapse of a predetermined period of time;
- and
- transmission means for transmitting the pass code to the information processing apparatus in response to the trigger signal generated by said trigger generation means,
- wherein said trigger generation means generates the trigger signal at a time interval not less than the predetermined period of time measured by said timer means.
An information processing apparatus which processes information received from an information input apparatus, wherein said information input apparatus comprises:
- memory means for storing a pass code assigned to the information input apparatus;
- trigger generation means for generating a trigger signal;
- timer means for measuring an elapse of a predetermined period of time;
- and
- transmission means for transmitting the pass code to said information processing apparatus in response to the trigger signal generated by said trigger generation means,
- wherein said trigger generation means generates the trigger signal at a time interval not less than the predetermined period of time measured by said timer means,
- said information processing apparatus comprising:
- receiving means for receiving the information from the information input apparatus;
- and
- processing means for processing the information received by said receiving means.
