摘要

PROBLEM TO BE SOLVED: To transmit/receive data between a data processing device without a radio communication function and an external device with the radio communication function. SOLUTION: A portable computer 3 is freely attachably/detachably connected to a video game machine 2 executing data processing. A communicating application 50 and a radio communication driver 70 for enabling radio communication between the computer 3 and an external device with a radio function 4 are supplied from the machine 2 to the computer 3 to make the computer 3 store a communication means control program of the application 50 and the driver 70 to allow the machine 2 and the device 4 to transmit/receive data through the computer 3.
