Abstract
A communication terminal equipment includes a body formed in a substantially parallelepiped form, housing communicating and receiving means therein. In this communication terminal equipment, a linear portion forming a side surface of the body and a projecting outwardly portion projected from the side surface are formed to be contiguous to each other. A single operation member which can be caused to undergo a movement operation in a forward direction and in a reverse direction constituting an operation mechanism for carrying out input to and switching of the communicating and receiving means housed within the body is provided at the projected portion. Only the single operation member is subjected to movement operation in the forward and reverse directions and makes it possible to carry out input to the communicating and receiving means and switching thereof. In addition, the single operation member includes a rotational operation member rotatably provided with respect to the body and the operation mechanism for carrying out input to and switching of the communicating and receiving means includes a switch mechanism controlled by the rotational operation member. Thus, miniaturization …
