PROBLEM TO BE SOLVED: To provide an information device which can select and execute only a function desired by a user from among a plurality of functions through simple operation using one key. SOLUTION: A DSB transmitter/receiver includes a function key 41, a function key allocation storage part 51, a selection switching part 52 and a function executing part 53. When the function key 41 is depressed long, a first signal is output and when the function key 41 is depressed short, a second signal is output. The function key allocation storage part 51 stores the plurality of functions. When the first signal is input, the selection switching part 52 switches to a state where one function among the plurality of functions can be selected sequentially for execution waiting. When the second signal is input, the function executing part 53 executes the one function in the execution waiting state. COPYRIGHT: (C)2011,JPO&INPIT
