Benefits of technology
[0007] It is an object of the present invention to provide a telephone set which makes it possible to easily perform various operations required particularly for conducting a radio telephone conversation with one hand while the telephone set itself is being held by the same hand.
[0008] It is another object of the present invention to simplify the procedure for selecting or operating a plurality of functions of the telephone set.
[0009] It is still another object of the present invention to provide a multi-functional telephone set, the number of buttons thereof being reduced as much as possible.
Problems solved by technology
Though the conventional portable radio telephone set is multi-functional, the operation procedure thereof is complex for a user when the series of operations described above is considered.
Furthermore, there is the possibility that the greater the number of buttons, the greater the chances that a button may be depressed erroneously when the button arrangement of a present portable radio telephone set is considered.
That is, in view of the complexity of such an operation procedure, it is not easy, as regards a conventional telephone set in which functions are selected by function buttons, to operate various buttons with only one hand while holding the telephone set itself in the same hand.

Embodiment Construction
[0025] Preferred embodiments of the present invention will be explained below with reference to the accompanying drawings of FIG. 1 through FIG. 9.
[0026] The appearance of a telephone set in accordance with the present invention will be explained first. FIG. 1 illustrates in perspective the overall appearance of the main body of the telephone set when the folded state thereof is released and it is placed in a use state. In this case, a receiver section 1 and a display section 2 are freely flexed and engaged with each other via a hinge 5. These sections are engaged with an operation section 4 via a joint portion 3 by which the telephone set is folded and rotated so as to be housed. A receiver (speaker for outputting received voice sound) 6 is provided in the central portion of the receiver section 1. When this receiver is brought into contact with the ear of a party (user) during a radio telephone conversation, a voice sound from the other party is heard. Since, as shown in the figu...
