Abstract

PURPOSE:To discriminate the code of picture information from a personal computer, etc., and to generate and record a character pattern by providing an equipment with a signal discrimination part, signal selection part, character generator, recording part, etc. CONSTITUTION:Picture information from a communication circuit 13 is demodulated by an MODEM35 to supply a picture signal 36 of every scanning section to the signal discrimination part 37 and a signal selection part 38. This discrimination part 37 discriminates a format signal of every scanning section and applies a discrimination signal 39 to the selection part 38. Then, the selection part 38 supplies the character generator 42 with a picture signal 41 of a section which is decided as an ASCCII code. This generator 42 generates a character pattern 43 corresponding to the ASCII code and the picture signal 43 is recorded by a picture recording part 44. Further, a picture signal 45 is supplied from the selector 38 to an information restoration part 46 at the time of a bit image signal to restore a picture signal 47, which is applied to the recording part 44 and recorded.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a facsimile device that receives image signals generated by a computer or the like.

[Prior art]

Personal computers can create image data containing a mixture of text and graphics. The created image data can be recorded on a cathode ray tube or copied with a printer, but it can also be sent electronically to a remote location using a facsimile device connected to a computer.

FIG. 1 shows the basic configuration of a conventionally used facsimile machine on the receiving side. Facsimile machine 1
The first modem (modem/demodulator) 12 demodulates the image information received from the communication line 13 and supplies it to the information restoration section 14 .

The information restoration section 14 restores the redundancy of the image information compressed by the sending facsimile machine, and supplies the redundancy to the image recording section 15 for recording.

However, in such a facsimile machine, the information restoration section 14 only performs processing to restore the redundancy of the received information, so if a code signal is manually input as a signal other than a bit image signal, it must be processed. I couldn't do it. In other words, for image data in which a code signal and a bit image signal are mixed, unless the code signal is converted into a corresponding bit image signal and transmitted,
I was unable to record this as received. With the spread of personal computers, a large amount of image data containing code signals is now being created, which is very inconvenient for users.

[Purpose of the invention]

In view of these circumstances, the present invention has been developed to combine code signals and bits.
It is an object of the present invention to provide a facsimile device that can receive image signals mixed with image signals.

[Structure of the invention]

The present invention includes a modem that receives an image signal, and a signal discriminator that determines for each signal in one scanning section whether the received image signal is assembled by a code signal or by a bit image signal corresponding to each pixel. a character generator that generates image information corresponding to the code signal based on the code signal; an information restoration section that restores the bit image signal to image information; and a signal discrimination section that discriminates the code signal. The facsimile machine is equipped with a switch noting means for supplying the bit image signal to the character generator, and a recording section for recording the image information.
Let me do it. When a code signal is received, a character pattern is generated by a character generator for that scanning section, and this is recorded.

〔Example〕

The present invention will be described in detail with reference to Examples below.

FIG. 2 shows a facsimile machine on the other side of the facsimile machine of this embodiment. A coaxial cable 22 whose one end is connected to the output terminal of the Nokuichi sonal computer 21 is connected to the input section 2 of the facsimile machine 23 on the sending side.
The other end is connected to 4. The image signal 25 for each scanning section output from the input section 24 is sent to the signal discrimination section 26.
supplied to The signal determining unit 26 determines whether the image signal 25 is composed of an ASCII code or a bit image signal. This determination is made by decoding the format signal attached to the leading end of the image data sent line by line from the personal computer 21.

The determination signal 27 is supplied to the human power section 24 . The human power section 24 has a built-in switch circuit for signal selection, and when it is determined that one line is constituted by ASCII code, the image signal 28 of that line is directly supplied to the modem 29. Further, when it is determined that one line is constituted by a bit image signal, this image signal 31 is supplied to the information compression section 32, and after the signal is compressed, it is supplied to the modem 29. The modem 29 modulates the input signal and sends it to the communication line 13.

FIG. 3 shows the facsimile machine of this embodiment. The image signal sent through the communication line 13 is
The signal is input to the modem 35 in the facsimile machine 34 and demodulated. The demodulated signal is stored in a line memory (not shown) and is supplied to both the signal discrimination section 37 and the signal selection section (switching means) 38 as an image signal 36 for each scanning section.

The signal determining unit 37 determines, for each image signal of one scanning section, whether these are assembled by ASCII code or by bit image signals corresponding to each pixel. For the above-mentioned sending-side facsimile machine 23, such a determination is made by decoding the sent format signal. Of course, it is also possible to employ other determination methods.

The determination signal 39 is supplied to the signal selection section 38.

(2) When it is determined that the scanning section is composed of ASCII codes, the signal selection section 38 supplies the image signal 41 of that section to the character generator 42. The character generator 42 generates a character pattern corresponding to each ASCII code, and supplies an image signal 43 obtained by line scanning the character pattern to the image recording section 44 .

On the other hand, when it is determined that one scanning section is made up of bit image signals, the signal selection section 38 supplies the image signal 45 of that section to the information restoration section 46 . The information restoration unit 46 restores the redundancy of the image information compressed by the facsimile machine 23 on the sending side. Then, the image signal 47 for each line obtained as a result is supplied to the image recording section 44.

The image recording section 44 synchronizes the two types of image signals 43 and 47 and performs line sequential recording to record image data.

In the above description, an ASCII code is used as the code signal, but it goes without saying that the code signal is not limited to this as long as it is a code signal that can be decoded by the facsimile machine on the receiving side.

〔Effect of the invention〕

As described above, the facsimile apparatus of the present invention can generate a character pattern based on a code such as an ASCII code and record an image. Therefore, it not only enables high-speed transmission, but also can be used as an image information receiving terminal device for a personal computer.
