There has been proposed a method or system for remotely controlling electric equipment such as.

For example, Japanese Patent Laid-Open No. 11-284757 discloses a mobile phone and a signal received from the mobile phone.
A control means for optically transmitting a remote control signal for remotely controlling a controlled device such as a television, an air conditioner, a VTR, etc. according to the received signal, and a plurality of remote controlled signals according to the remote control signal optically transmitted from the control means. A mobile phone remote control system including a control device is disclosed, and such a remote control system enables a reservation operation for home electric appliances using a mobile phone.

[0005]

However, in the system disclosed in the above publication, the control unit provided in the control means for optically transmitting the remote control signal analyzes the signal received from the mobile phone, After converting to a format compatible with the desired controlled device, a remote control signal for turning off the power of the controlled device from the optical transmission unit is optically transmitted to the controlled device. It is not disclosed at all how this control unit converts to a format compatible with the controlled device, and it is unknown, and it is expected that this part will be considerably complicated both in terms of software and hardware. There was a flaw.

In view of the above-mentioned conventional circumstances, the present invention has been made to solve the above-mentioned drawbacks inherent in the prior art. Therefore, the object of the present invention is to provide a single portable element with a relatively simple structure. It is an object of the present invention to provide a novel mobile phone device with a remote control function, which makes it possible to easily control a controlled device.

[0007]

In order to achieve the above object, a mobile phone with a remote control function according to the present invention has a function mode switch for switching between a telephone function and a remote control function, and various home electric appliance manufacturers. A remote control code storage IC in which a plurality of infrared signal wavelength codes are stored so as to correspond to the remote control function, and a number button having a plurality of selection buttons for accessing the remote control code storage IC and reading out a desired remote control code. Infrared emission means for supplying an remote control code read from the remote control code storage IC by operating the number button and generating an infrared signal of a wavelength corresponding to the remote control code.

[0008]

BEST MODE FOR CARRYING OUT THE INVENTION Next, a preferred embodiment of the present invention will be described in detail with reference to the drawings.

FIG. 1 is a block diagram showing an embodiment of the present invention, and FIG. 2 is a perspective view showing an example of a system according to the present invention.

[0010]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring to FIG. 1, a mobile phone or a cordless phone 1 is equipped with a remote control function changeover switch 2 for switching between a normal phone mode and a remote control function, which is normally used as a phone function. The telephone 1 to be operated functions as a remote controller that realizes remote operation of home electric appliances when switched to the remote controller by the remote controller function changeover switch 2.

A remote control code storage IC 6 in which a plurality of remote control functions 3 are stored in advance is incorporated in the telephone 1 so as to be compatible with remote controls of various home electric appliance manufacturers.

That is, the remote control code storage IC 6 stores the function of the remote control used by each home appliance maker and the wavelength of the signal, and by pressing the number set by the number button 4 of the telephone 1, Remote control code memory IC6
It is possible to call the remote control function 3 of the home electric appliance which is the controlled device desired by the operator and stored in.

Further, by operating the number button 4 assigned in advance, a signal is transmitted from the infrared ray emitting section 5 and it can be used as a remote controller for home electric appliances.

An infrared output device (not shown) capable of outputting an infrared signal having a wavelength (frequency) corresponding to the remote control function of the controlled device of various home electric appliances manufacturers and models is provided to the infrared light emitting section 5. No.) is built in, and an infrared signal desired by the operator is output by operating the number button 4.

[0015]

Next, the operation of the embodiment of the present invention will be described.

By calling the code of the home electric appliance to be used stored in the telephone 1 with the number button 4 of the telephone 1 and setting the code, it can be used as a remote controller for the home electric appliance.

That is, first, the changeover switch 2 is operated to set the switch 2 in the remote control function mode.

Next, by pressing the number button 4, the remote control function 3 corresponding to the desired number of the number button 4 set can be read from the remote control code storage IC 6.

Subsequently, the operator supplies the code of the remote control function 3 corresponding to the set number of the read number button 4 to the infrared emitting section 5.

By the above operation, an infrared signal having a desired wavelength is generated from the infrared light emitting section 5, and the cordless telephone 1 functions as a remote controller.

[0021]

Other Embodiments The present invention is intended for a cordless telephone, but a wired telephone can also be used in a similar manner by installing an infrared transmitter in the receiver.

[0022]

The present invention is constructed and operates as described above, and according to the present invention, the following effects can be obtained.

With the increase in the number of home electric appliances owned by individuals, it has been necessary to use several kinds of remote controllers in the past, but the present invention enables the use of a plurality of kinds of home electric appliances only with this telephone.

In the present invention, the remote control code storage I
Infrared signals of different wavelengths (frequencies) are output from the infrared light emitting unit 5 corresponding to the remote control function code read from C6, so the infrared signals corresponding to manufacturers A, B, C ... A ', B', C '... is output, and infrared signals L', M ', N' ... are output corresponding to the models L, M, N ... As a result, a single telephone can be used as a mobile telephone, and it is possible to remotely control all types of home appliances.
