In this case, in order to confirm the visitor visually, an infrared-ray signal is sent from an infrared-ray generating section 9 to a photodetector section 8 of a television receiver 3 by the key operation of the telephone set 6, the receiver 3 is switched to the video input to display the video image of the visitor. Thus, the reception with the visitor is attained while observing the figure of the visitor on the receiver 3 with the simple operation of the telephone set 6 only.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a cordless telephone device for general household use or a so-called home telephone.

2. Description of the Related Art As an example of a conventional cordless telephone device, a structure as shown in FIG. 2 is known.

In Figure 2, 1 is a camera intercom slave unit, 2 and 3 are a monitor TV unit that displays images based on the video signal sent from the camera intercom 1, and a general TV receiver (with a video input terminal). , 4 is the main device of the home telephone connected to the monitor television unit 2, 5 is the cordless telephone body connected to the main device 4, 6 is a cordless telephone wirelessly connected to the cordless telephone body 5, and 7 is the television receiver 3. This is an optical remote control device that emits infrared rays as an optical remote control signal to the light receiving section 8 of the optical remote control device.

The operation of the above structure will be explained below.

When a visitor makes a call using the camera door intercom handset 1, the camera door intercom handset 1 activates the monitor TV unit 2 to display the image of the visitor taken by the camera door intercom Senki 1, and also sounds a ring tone to notify the visitor. let people know that someone is there. On the other hand, the cordless telephone 6 allows the camera intercom slave unit 1 to respond and talk to the visitor via the cordless telephone body 5, the main device 4, and the monitor television unit 2.

At this time, to visually confirm the visitor, either go to the location where the monitor television receiver 2 is installed, or emit infrared rays from the optical remote control device 7, and switch the television receiver 3 to video input (7U source). If it is not on, turn on the power), and display the image of the Ministry of Visitation based on the above video signal.

Problems to be Solved by the Invention However, in the above-mentioned conventional telephone set, in order to visually confirm the visitor using the television receiver 3 when talking with the visitor, a cordless telephone 6 and a separate device are required. There is a problem in that the optical remote control device 7 that remotely controls the television receiver 3 must be operated at the same time, which is cumbersome.

The present invention solves these conventional problems, and it is possible to talk to visitors by simply operating a cordless telephone, and also to remotely control a television receiver. The object of the present invention is to provide a cordless telephone device that can display images of visitors.

Means for Solving the Problem The technical solution of the present invention for achieving the above-mentioned objective is as follows:
This cordless telephone is equipped with a transmitter that transmits an optical remote control signal to a television receiver that can display images of visitors.

Preferably, the optical remote control signal transmitting means is driven by a key operation.

Therefore, according to the present invention, when answering or talking to a visitor using a cordless telephone, an optical remote control signal is transmitted from the optical remote control signal transmitting means of the cordless telephone to remotely control the television receiver. A visitor to this TV set:
It is possible to display v-images.

EXAMPLE Hereinafter, an example of the present invention will be described with reference to the drawings.

FIG. 1 is a schematic configuration diagram showing a cordless telephone device according to an embodiment of the present invention.

In this embodiment, the same parts as those of the conventional example shown in FIG. 2 are given the same reference numerals, and the explanation thereof will be omitted, and the different configuration will be explained.

The feature of this embodiment is that the cordless telephone 6 is provided with infrared light emitting means that emits infrared light as an optical remote control signal by key operation, and as shown in FIG. 1, the infrared light emitting section 9 is exposed. has been done.

In the above structure, its operation will be explained below.

When a visitor makes a call using the camera door phone handset 1, the camera door phone Senki 1 starts the monitor television set 2, displays the image of the visitor captured by the camera door phone handset 1, and sounds a ring tone to notify the visitor. let people know that someone is there. On the other hand, the cordless telephone 6 allows the camera intercom 1000 to answer and talk to the visitor via the cordless telephone main body 5, the main device 4, and the monitor television unit 2. At this time, in order to visually confirm the visitor, the infrared light emitting means is driven by the key operation of the cordless telephone 6, and the infrared light emitting part 9 sends an infrared signal to the light receiving part 8 of the television receiver 3. Switch the television receiver 3 to video input and display the image of the visitor. Therefore, by a simple operation, it is possible to see the visitor on the television receiver 3 while attending to the visitor.

Effects of the Invention As described above, according to the present invention, when answering or making a call to a visitor using a cordless telephone, an optical remote control signal is emitted from the optical remote control signal transmitting means of the cordless telephone, and the television receiver is It is possible to remotely control the TV receiver and display the visitor's image on the TV receiver. In this way, it is possible to talk to a visitor by simply operating the cordless telephone, and also to remotely control a television receiver to display an image of the visitor on the television receiver.
