Cordless telephone
First Claim
1. A cordless telephone apparatus including a base unit connected to a telephone line for communication, and a handset, operatively connected to the base unit by radio waves, including a speaker, a microphone, a transmitting and receiving circuit for communicating with the base unit by radio waves, transforming the signals from a caller into acoustic sound by the speaker, and second the output from the microphone to the caller, and a battery for providing the transmitting and receiving circuit with electric power, the handset further comprising:
- display means for indicating an in-service state of the cordless telephone activated for communication;
contact detecting means for detecting contact of a user with an area proximate to the speaker;
activation detecting means for detecting activation of the cordless telephone for communications to detect the in-service state; and
control means operatively connected to the display means, the contact detecting means and the activation detecting means, for controlling the display means to stop indicating an in-service state when an area proximate to the speaker is detected to be in contact with a user and an in service state is detected, in response to the contact detecting means and activation detecting means, and for controlling the display means to indicate an in-service state when an area proximate to the speaker is not detected to be in contact with a user and an in service state is detected; and
the handset battery means for electrically powering the handset.

Abstract
A cordless telepone includes a base unit connected to a telephone line so as to communicate by radio waves for talking and a hanset. The handset includes a speaker, a microphone, and a transmitting and receiving circuit for communicating with the base unit by radio waves, transforming the signals from the caller into acoustic sound by the speaker, and sending the output from the microphone to the caller. The handset further includes a battery for providing the transmitting and receiving circuit with electric power. Still further, the handset includes a device for display to indicate the in-service state, a device for detecting the contact of the speaker area with a part of the body, a device for detecting talking to detect the in-service state, and a device for controlling to stop the display action of the display device when the speaker area is in contact with a part of the body and is in service this stopping of the display device occurs response to the output from the contact detecting device and the talk detecting device. The control device further affects the display action by the display device while the speaker area is not in contact with the body during service. The handset, in this device, is electrically powered by a battery.

6. A cordless telephone apparatus including a base unit connected to a telephone line and a handset operatively connected to the base unit via radio communication and equipped with a display device for indicating an in-service state of the handset, the handset comprising:
-
contact detecting means for detecting contact when a part of the body of the user contacts with an area proximate to a speaker of the handset, and stopping means for stopping the display device from indicating the in-service state when a part of the body of the user is detected to be in contact with an area proximate to the speaker of the handset, in response to the contact detecting means.

7. A handset of a cordless telephone including a base unit and the handset including a speaker and a transmitter for communicating, by radio communications, with the base unit, the handset further comprising:
-
display means for displaying indication of the cordless telephone being in-service; detecting means for emitting a signal upon detecting contact of a user to an area of the handset in close proximity to the speaker; and control means, operatively connected to said display means and said detecting means, for controlling said display means to display indication of the cordless telephone being in-service upon not receiving an output signal from said detecting means when the cordless telephone is in service and for controlling said display means to stop displaying indication of the cordless telephone being in-service upon receiving an output signal from the detecting means when the cordless telephone is in service. - View Dependent Claims (8, 9, 10, 11, 12, 13, 14, 15)
