Description

DETAILED DESCRIPTION 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.

This receiver consists of a conventional television imager part, a facsimile signal demodulator that detects the multiplexed facsimile signal, and a recording device that operates based on the demodulated facsimile signal and creates a hard copy.

In this type of machine, it would be convenient if the recording device could be operated based on a signal other than the facsimile signal multiplexed with the television signal so that it could be used for multiple purposes.

Accordingly, an object of the present invention is to provide a television facsimile receiver that can be used for multiple purposes, and an embodiment shown in the drawings will be described below.

1 is a normal antenna for television 2 is a part of a normal television imager; 3 is a facsimile signal demodulator;
demodulates and derives the facsimile signal multiplexed with the television signal. The facsimile signal derived by the facsimile signal demodulator 3 is transferred to the recording device 5.
As shown by the dashed line in the figure, a hard copy can be obtained in the recording device 5 based on the facsimile signal, which is equivalent to a conventional television facsimile receiver.

In this embodiment, a switch 4 is provided to change over the signal source for operating the recording device 5, and when the switch 4 is connected to the a side, the facsimile signal is introduced to the recording device 5, and the facsimile signal is used as in the conventional case. A hard copy will be created.

This switch 4 introduces a signal from the image information detection device 9 or the cassette tape device 7 to the recording device 5 when connected to the b side or the c side.

This image information detection device 9 is used to copy any document, and reads image information of the document and decomposes it into pixels to obtain and output an image signal in the same format as a facsimile signal.
Therefore, by turning the switch 4 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 it is possible to copy any original document. becomes.

The facsimile signal from the facsimile signal demodulator 3 or the image signal from the image information detecting device 9 is selected by the switch 6 and introduced into the cassette tape device 7 to be stored on the cassette tape.
The information stored on this cassette tape is read out by the cassette tape device 7 and introduced into the recording device 5 through the C side of the switch 4 to create a hard copy.

Here, the control device 8 of the cassette tape device 7
It is convenient to have a so-called cue function for selecting any piece of information from a tape that stores many types of information. It goes without saying that various systems for cueing functions are known and can be adopted as appropriate. It goes without saying that in place of the cassette tape device 7, other storage means capable of recording signals in the facsimile signal band may be employed.

According to the television facsimile receiver of the present invention,
As mentioned above, it is possible to make hard copies from facsimile signals multiplexed with television signals, but in addition to this, it is also possible to make copies from any original document, making it convenient and versatile. It is also possible to temporarily store facsimile signals and create hard copies as needed.

Claims (1)

[Scope of Claims] 1. A television facsimile receiver having a recording device that receives a facsimile signal multiplexed with a television signal and transmits and obtains a hard copy based on the facsimile signal, reads image information of a document. An image information detection device for decomposing into pixels and obtaining an image signal of the same format as the facsimile signal is provided, and at least one of the facsimile signal and the image signal obtained by the image information detection device is selectively sent to the recording device. A television facsimile receiver characterized in that it can be introduced and recorded. 2. A signal obtained by reading out a storage medium such as a cassette tape in which the facsimile signal and the image signal are once stored is selectively introduced into the recording device as the facsimile signal or the image signal. A television facsimile signal according to claim 1, characterized in that:
