BRIEF SUMMARY
DESCRIPTION
1. Technical Field
The present invention relates to a communication terminal apparatus, and more particularly to a communication terminal apparatus having a speech input device which includes a microphone and is arranged for movement between an on-hook position on a main shell and a call position, when a call is enabled, and the speech input device is distanced from the on-hook position, the position of the speech input device relative to the main shell is detected and its signal is used for controlling the entry action of input controls.
2. Background Art
As portable radio phone systems have widely been in service, a variety of multi-function communication terminal apparatuses are now available for communications in the systems. Such a multi-function communication terminal apparatus offers auto-dial or speed call for selecting one from a plurality of telephone numbers stored in a memory installed in the main shell and dialing it automatically, as well as registering any name and number to a list of telephone numbers in the memory.
The communication terminal apparatus for use with a portable radio phone system is of a hand-held type which is essentially required for having minimum size and weight. For the purpose, each of the conventional terminal apparatuses is equipped with a sheet type of dial keys, a highly advanced battery(s), and a state-of-art integrated circuit which all are light weighted.
As every communication terminal apparatus has a transmitter and a receiver spaced from each other by a distance between the mouth and the ear, its oversize depends on the distance between the transmitter and the receiver. Commonly, the transmitter is spaced by 13.5 cm to 14.3 cm from the receiver and at an angle of 23.3 to 13.4 degrees to the same. For minimizing the overall size of the apparatus while satisfying those requirements, the transmitter is separated in structure from the receiver; the two, transmitter and receiver, blocks of the apparatus are arranged foldable to each other. As the transmitter and receiver of the communication terminal apparatus remain folded down when not used, their dimensions are minimized to a so-called pocket size. When a call is made, the transmitter and receiver are opened up to the mouth-to-ear distance.
DISCLOSURE OF THE INVENTION
It is an object of the present invention to provide a communication terminal apparatus having a main shell minimized in size and weight and adapted for performing multiple functions.
It is another object of the present invention to provide a communication terminal apparatus having multi-function controls without increasing the number of control keys, thus minimizing the overall size of its main shell.
It is a further object of the present invention to provide a communication terminal apparatus arranged which detects the position of a speech input device relative to a main shell in a call mode, and uses its signal to control the action of input controls in order to carry out each control operation correctly without any unnecessary motion.
For achievement of the above objects, a communication terminal apparatus according to the present invention comprises: a speech input device arranged movable from a position adjacent to a main shell to a position distanced from the main shell for calling; a transmitter/receiver circuit for modulating and transmitting an output signal from the speech input device, and demodulating and reproducing an input signal; an input control mechanism composed of a plurality of operating keys; a detector mechanism for detecting the position of the speech input device; and a controller device responsive to a detection signal from the detector mechanism for controlling the action of the input control mechanism as well as conducting the transmission and receiving actions of the transmitter/receiver circuit.
The controller device of the apparatus is arranged to disable the action of the input control mechanism when the detection signal from the detector mechanism indicates that the speech input device is located at
