PROBLEM TO BE SOLVED: To provide a housing device to be shared by a plurality of data radio communication modules having different communication speeds. SOLUTION: When one of UART module 1a, USB module 1 and SD module 1c is inserted into a portable jacket 7, a signal representing the type of the inserted module is input in a CPU 37 from one of the UART module 1a, USB module 1 and SD module 1c inserted into the portable jacket 7 through a bypass route provided in a UART interface IC 40a. The CPU 37 changes over an interface changeover switch 44, and the inserted module is connected to the CPU 37 via one of UART interface IC 40a, USB interface IC 40b and SD interface IC 40c corresponding thereto.
