Portable telephone equipment for biasing a switching member to a normally neutral position

A communication terminal equipment comprising:

• a rigid body formed into a substantially parallelepiped shape and accommodating communicating means and receiving means therein, the rigid body having a projected portion bulging outwardly from a substantially linear portion of a side surface of the rigid body, the linear portion and the projected portion being contiguous with each other;
• and
• operation means provided at the projected portion of the rigid body for carrying out one of input operations to the communicating means and the receiving means and switching operations of the communicating means and the receiving means, the operation means including a single operation member movable in a forward direction and in a reverse direction and having a rotational operation member rotatably provided with respect to the body and switch means controlled by the rotational operation member, wherein the switch means includes
• a switching member rotatably attached to the body such that rotating the rotational operation member actuates the switch means, and
• biasing means for biasing the switching member to normally neutral position such that when the switching member is return to the neutral position by the biasing means the rotational operation member is returned to a neutral position.

A portable telephone equipment comprising:

• communicating and receiving means;
• display means for displaying information based on a transmitting operation and a receiving operation by the communicating and receiving means;
• a plurality of input keys for carrying out an input operation to go the communicating and receiving means;
• a rigid body having a substantially parallelepiped shape and accomodating the communicating and receiving means therein, wherein the display means and the plurality of keys are disposed on a front surface of the rigid body, and having on a side surface of the rigid body a projected portion that protrudes outwardly from the side surface of the rigid body;
• and
• operation means provided at the projected portion the rigid body for carrying out input operations to the communication means and receiving means and for carrying out switching operations of the communicating and receiving means, the operation means provided with a single operating member movable in a forward direction and in a reverse direction, and the operation means further includes biasing means for biasing the switching member to a normally neutral position such that when the switching member is returned to the neutral position by the biasing means the rotational operation member is returned to a neutral position.
