Abstract

PURPOSE:To attain multi-purpose application by providing a picture information detector or the like receiving a G3 or G2 facsimile signal sent from a telephone line to obtain a picture signal of the same format as that of a TV facsimile signal. CONSTITUTION:The picture information detector 6 receives a G3 or G2 facsimile signal sent from telephone line and outputs a picture signal of the same format as that of a TV facsimile signal. Thus, in applying a switch 4 to the position (b) to introduce the picture signal to the device 5, a hard copy is generated based on the picture signal and the reception recording of the G3 or G2 facsimile is attained. In a control signal detector 7, when the TV facsimile signal and the G3 or G2 facsimile signal are received simultaneously, the G3 or G2 facsimile signal is recorded selectively from the TV facsimile signal according to the preset priority in the detector 7 depending on the content of the control signal. Thus, the TV facsimile receiver is used for multi-purpose.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a television facsimile receiver that receives radio waves broadcast by superimposing a facsimile signal on a television signal.

BACKGROUND OF THE INVENTION Conventionally, a conventional television facsimile receiver consists of a conventional television imager part, a facsimile signal demodulator for detecting a multiplexed facsimile signal, and a hard copy machine operating on the basis of the demodulated facsimile signal. A recording device is used to create a stone composed of stones.

Problems to be Solved by the Invention In this model, it would be convenient if the recording device could be used for multiple purposes, such as operating on a signal other than the facsimile signal multiplexed with the television signal. be.

The present invention has been made in view of the above-mentioned conventional situation,
SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide a novel television facsimile receiver that can be used for multiple purposes.

Means for Solving the Problems In order to achieve the above object, a television facsimile receiver according to the present invention receives a G3 or CRS facsimile signal transmitted from a telephone line, and receives a G3 or CRS facsimile signal in a format equivalent to that of the television facsimile signal. An image information detection device for obtaining an image signal is provided, and at least one of the television facsimile signal and the image signal obtained by the image information detection device can be selectively introduced into a recording device and recorded. When a television facsimile signal and a 03 or G2 facsimile signal are received at the same time, one of the facsimile signals can be recorded preferentially.

Embodiment Next, a preferred embodiment of the present invention will be specifically explained with reference to the drawings.

FIG. 1 is a block diagram showing one embodiment of the present invention.

In FIG. 1, the reference numeral 2 indicates a conventional antenna for television, and the reference numeral 2 denotes a conventional television antenna. Reference numeral 3 denotes a facsimile signal demodulator, which demodulates and derives the facsimile signal multiplexed with the television signal. By introducing the facsimile signal derived by the facsimile signal demodulator 3 directly into the recording device 5 as shown by the dotted line in Figure 1, a hard copy can be obtained in the recording device j based on the facsimile signal. It is equivalent to a conventional television facsimile receiver.

In one embodiment of the present invention, a switch is provided to switch the signal source for operating the recording device S, and the switch l is set to a.
When the facsimile signal is connected to the recording device 5, the facsimile signal is introduced into the recording device 5, and a hard copy is created based on the facsimile signal as in the conventional case.

When connected to the switch fb side, a signal from the image information detection device 6 is introduced to the recording device 3.

This image information detection device 6 detects G
3 or G facsimile signal received.

To obtain and output an image signal in a format equivalent to a television facsimile signal. Therefore, by turning the switch to the b side and introducing this image signal into the recording device 5, a hard copy can be created based on the image signal, and the reception and recording of G3 or G2 facsimile signals can be performed. Can be done.

Further, in the control signal detector 7, which has a function of detecting a control signal of the television facsimile from the demodulated output of the facsimile signal demodulator 3 of the television facsimile, and a function of detecting a control signal of the G3 or G-co-facsimile IJ signal, Television facsimile signal and 03
Or when Gx 7 axis signals are received simultaneously, each ? According to the priority set in advance in the control signal detector 7 depending on the content of the 1ilJ control signal, the television facsimile signal, G3 or G
-7 Select the axis IJ signal and record the reception. The simplest form is a method in which, regardless of the content of the control signal, when a television facsimile signal and a 03 or G-co facsimile signal are received at the same time, one of them is selected preferentially.

Effects of the Invention As described above, according to the television facsimile receiver according to the present invention, it is possible not only to create a tocoby from a facsimile signal multiplexed with a television signal, but also to receive G3 or Gp facsimile. It can also be used as a machine, and also transmits television facsimile signals and
When 3 or Gx facsimile signals are received at the same time, one can be selectively received depending on the preset priority order or the content of the control signal in each facsimile signal.

Claims (2)

[Claims] (1) In a television facsimile receiver having a recording device that receives a facsimile signal transmitted multiplexed with a television signal and obtains a hard copy based on the facsimile signal, G_3 transmitted from a telephone line
Alternatively, an image information detection device is provided that receives the G_2 facsimile signal and obtains an image signal in the same format as the television facsimile signal, and at least one of the television facsimile signal and the image signal obtained by the image information detection device is provided. is selectively introduced into the recording device for recording, and furthermore, when the television facsimile signal and the G_3 or G_2 facsimile signal are received simultaneously, one of the facsimile signals can be recorded preferentially. A television facsimile receiver featuring: (2) When the television facsimile signal and the G_3 or G_2 facsimile signal are received simultaneously, the G_3 or G_2 facsimile signal and the control signal included in the television facsimile signal are detected, and depending on the content of the control signal, the G_3 or G_2 facsimile signal is detected. Claim (1) characterized in that facsimile signals or television facsimile signals are recorded preferentially.
