INFORMATION INPUT/OUTPUT DEVICE AND SYSTEM USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide an information input/output device which does not increase units at the periphery of a computer and causes no hindrance to the use of a communication cable. SOLUTION: A microinformation recording and reproducing device 40 can be integrated with a housing 11 which has a pointing device substrate 115 inside and a device interface 30 for information input to and output from the circuit of the pointing device substrate 115 and information input to and output from the microinformation recording and reproducing device is built in the housing 11.
