A communication terminal apparatus includes a disc member that is supported such that a portion thereof protrudes outside the body case, and that is rotated to output a signal corresponding to its rotation direction and rotation angle; first switch operated by pressing the disc member toward the body case; second and third switches separately operated by pivoting the disc member about a pivot axis parallel to the rotation plane and orthogonal to the pressing direction; a storage device storing a plurality of items; a display device displaying a cursor and a plurality of items read from the storage device; and a control device for moving the cursor displayed in the display device and for selecting and executing the displayed items or other items required for communications in accordance with the operations of the disc member and the first, second, and third switches.

Rotatively-operated switch apparatus and communication terminal apparatus

In a voice receiving mechanism and a handset, an ear pad and a speaker are secured to a ball of a ball joint, and a grip portion supports a ball holder of the ball joint. Therefore, the ear pad, and so on are swingable in any direction relative to the grip portion, and the ear pad, can be brought into close contact with the ear. Further, a leaf spring applies a braking force to the ball. So that, even after the ear pad is separated from the ear, the orientation (direction and angle) of the ear pad, can be kept so that the ear pad can come into close contact with the ear.
