Remote controller using cordless phone

The present invention relates to a remote controller for remotely controlling an electronic device such as a television. In particular, the present invention relates to a remote controller using a cordless telephone for use as a cordless telephone and a remote controller by integrating the circuit of the remote controller in the cordless telephone.

In general, the remote controller used to remotely control a television, etc., is a single product. However, since such a general remote controller is separated from a device such as a television, there is an inconvenience in that its location cannot be grasped due to the user's sub-circumference. In order to solve the problem of the conventional remote controller, if the user wants to find a remote controller by installing a remote controller storage slot in a television or having a remote controller positioning alarm transmitter in the television and an alarm signal receiver and an alarm unit in the remote controller. There is a devise to press the alarm button installed on the TV to listen to the alarm generated by the remote controller and to find the location. However, such a conventional remote controller has a problem in that the above separate devices must be installed in the television and the remote controller in order to use the remote controller.

The present invention has been made to solve the problems of the conventional remote controller, and an object of the present invention is to provide a device for a remote controller using a wireless telephone by integrating a remote controller such as a television in a home wireless telephone. In order to achieve the above object of the present invention, the key matrix of the wireless telephone is shared with the microcomputer, and when the transmission / reception signal of the telephone is not input so that it does not interfere with the transmission and reception of the telephone, it can be used as a remote controller that can remotely control the television. The power of the remote controller is turned on, and when the incoming / outgoing signal of the telephone is input, the on / off switch of the telephone is turned on and the above switching signal is applied to the microcomputer. Thus, the remote controller is switched off while the telephone is in use. The configuration for turning off is shown as an example.
