Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a facsimile receiving device that displays each document image based on a plurality of facsimile signals on one recording display surface.

[Conventional technology]

This type of device is capable of storing the calligraphic signals obtained by multiple facsimile signals for one screen each, and then reading out the stored contents at high speed for the multiple times, and speeding up the speed for the multiple times. A structure (hereinafter referred to as the first prior art) in which a plurality of calligraphy and image signals can be recorded and displayed in a short time by feeding them to the printing unit is disclosed in Japanese Patent Application Laid-Open No. 1983-1999.
148910 and others.

In addition, after the calligraphy signals for all pages for multiple calligraphy image screens have been stored, they are rearranged and read out at high speed for recording and display (hereinafter referred to as the second prior art). 100667 and others.

Furthermore, there is a structure in which a plurality of facsimile signals are temporarily stored, read out at a faster speed than the calligraphy and image transmission device, and the plurality of calligraphy images are recorded and displayed in parallel by recording and scanning at a constant speed (hereinafter referred to as the third prior art). ) is disclosed in Japanese Patent Application Laid-Open No. 56-66961.

[Problem to be solved by the invention]

In the first prior art described above, since the recorded display cannot be obtained until after each calligraphy signal has been stored for one screen or more, it is difficult to immediately check whether the facsimile signal being received is the intended one. In addition, since the recording display time is shortened by increasing the speed of recording scanning, there are disadvantages such as the need for a recording scanning mechanism that is faster by the number of times.

The above-mentioned second conventional technique also has exactly the same disadvantages as the above-mentioned first conventional technique.

In the third conventional technique described above, the disadvantages of the first conventional technique and the second conventional technique are solved, but since the scanning speed of the recording scan is fixed constant, several different document and image transmission speeds are possible. When selecting and receiving multiple facsimile signals, the scanning speed must be set to correspond to the slowest expected calligraphic transmission speed. Even when a combination of objects is used, there is a disadvantage that recording and display can only be performed at a fixed, slow scanning speed.

Specifically speaking, facsimile signals have different calligraphy transmission speeds depending on the transmission method of the transmitting station.
revolutions/minute, 90 revolutions/minute, 120 revolutions/minute, 240 revolutions/minute
minutes (rotations/minute corresponds to scans/minute), and in order to be able to display all records, the scanning speed must correspond to the minimum speed of 60 revolutions/minute, so Even if I am receiving facsimile signals of 120 rpm and 240 rpm,
This has the disadvantage that it is only possible to record and display at a scanning speed of 60 scans/minute, which is the lowest speed.

For this reason, there is a problem in that it is desired to provide something that solves these inconveniences with a simple configuration.

Furthermore, it would be convenient for the user if the positions of a calligraphic image with a slow transmission speed and a calligraphy image with a fast transmission speed could be swapped arbitrarily, and there is a problem in that this swapping can be done with a simple configuration.

[Means to solve the problem]

This invention applies each readout signal obtained by reading out the stored contents of each calligraphy signal of a plurality of facsimile signals as described above to one recording scan, and generates a calligraphy image corresponding to each of the above-mentioned calligraphy signals. A facsimile receiving device configured to perform recording scanning, that is, parallel writing scanning, arranged in parallel on one recording display screen, includes a different transmission speed receiving means for receiving the above-mentioned plurality of facsimile signals having different calligraphic transmission speeds; By providing a slow speed selection scanning means that selects a scanning speed corresponding to the slower one of the above-mentioned different calligraphy and image transmission speeds and performs simultaneous writing scanning, it is also possible to record data on the side in which the above-mentioned simultaneous writing scanning is performed. A destination to obtain a starting point signal corresponding to the start position of the document image to be scanned, that is, the starting position of the forward document image, and an intermediate point signal corresponding to the start position of the document image to be recorded and scanned in the backward direction, that is, the starting position of the backward document image. a forward-sequence start point signal means; and a forward-sequence sequence for recording and displaying the above-mentioned forward-sequence image and backward-sequence image interchangeably by exchanging the above-mentioned start point signal and intermediate point signal for the above-mentioned readout; The above problem can be solved by providing a replacement means and the like.

〔Example〕

Examples will be described below with reference to figures.

In addition, in the following explanation, facsimile is used.
It is abbreviated as FAX.

In Figure 1, two similar configurations are arranged at the top and bottom. First, to explain the configuration arranged at the top, the radio wave frequency and calligraphy transmission speed of FAX radio waves O differ depending on the transmitting station. Therefore, the station setting means 4C selects the target frequency f1 from the branch signal b1 obtained by branching the received signal a of the antenna 1 by the distribution circuit 2, and also selects the synchronization frequency f1 in FIG. 2 corresponding to the calligraphy transmission speed. A rotation speed K1 is set for selecting the period T1.

The receiving circuit 3A amplifies and detects the selected radio wave and outputs a detected signal c1.

The synchronization detection circuit 5A detects the synchronization signal d1 of the detected signal c1.

The drive circuit 6A drives the recording pen scanning belt (not shown) of the recording device 7B at a scanning speed corresponding to the slow calligraphy transmission speed of the received FAX signal, and also scans the recording paper. 71
Send B at the desired transition speed.

The intermediate inspection means 8B detects when a recording pen (not shown) reaches the recording start point of the calligraphy image 72c on one half (the upper half in the illustrated example) of the recording paper 71B, and outputs an intermediate point signal e2.

The converting means 9A stores and accumulates the drawing signal r1 of the detection signal c1 while shifting the storage position for each synchronization signal d1, reads out the stored signal sequentially for each intermediate point signal e2, and generates an output signal for recording. h1
It is outputted as and given to the recording pen of the recording device 7B.

A specific example of this conversion means 9A will be explained with reference to FIG.

In the detection signal c1 of the FAX radio wave, as shown in FIG.
is being sent.

After AD converting this as necessary (not shown), the writing signal r1 is made to correspond to the synchronizing signal d1 for each scanning line, and then sent to the input buffer memory 91.
The data stored in the input buffer memory 91 is stored at a specified address in the main memory 93 according to a command from the CPU 92 before receiving the drawing signal r1 of the next scanning line.

The data transfer for this purpose is performed within the period of the synchronization signal d1, and the data of the drawing signal r1 each time is sequentially moved to the storage location in the main memory 93, and is stored, for example, at a different storage address. On the other hand, the calligraphy data stored in the main memory 93 is stored in the CPU 9 while the input buffer memory 91 is storing the next calligraphy signal r1.
In response to the command No. 2, the data is transferred from the main memory 93 to the output buffer memory 94 one scanning line at a time.

The calligraphy data in the output buffer memory 94 is sequentially read out in accordance with the time when the recording pen scans the width of the calligraphy image 72c in accordance with the intermediate point signal e2, and this output is DA-converted and amplified as necessary. When the recording pen is connected to a recording circuit (not shown) for outputting the recording output signal h1 to the recording pen and records one scanning line, the output buffer memory 94 receives the following signals in sequence according to instructions from the CPU 92. The drawing data is transferred to the main memory 93 and rewritten.

On the other hand, as a result of this recording operation, the storage address where the calligraphy data for one scanning line used for the storage was stored in the main memory 93 is vacated, and a circular storage operation is performed so that the subsequent new calligraphy data is stored. It operates as a so-called rotary memory. The program memory 95 is a ROM (read-only memory) in which program data for causing the CPU 92 to perform the above command operations is written.

Next, the configuration including the configuration disposed on the lower side of FIG. 1 will be explained.

As shown in FIG. 2, the received signal a includes detection signals c1,
When set to c2, radio waves with different calligraphy and drawing transmission speeds are being received, such as synchronization periods T1 and T2, and the distribution circuit 2 gives the branched signals b1 and b2 to the two receiving circuits 3A and 3B, respectively. .

When the station setting means 4C sets the frequencies f1 and f2 and the rotation speeds K1 and K2 of the two FAX radio waves to be received, the station setting means 4C sets the frequency f1 of the radio waves with the farthest rotation speed, that is, the frequency f1 of the radio waves due to the synchronization period T1, to the first one. In the receiving circuit 3A, the slower rotational speed K2 of the other lung, that is, the frequency f2 due to the synchronization period T2, is set to the second receiving circuit 3B, and the slower rotational speed K2 is set to the drive circuit 6A. The selection operation is made by means such as a comparator circuit so as to make the setting.

Therefore, the detection signal c2 of the receiving circuit 3B includes the detection signal c2 of FIG.
The synchronizing signal d2 shown in FIG. 2 is obtained at B.

The drive circuit 6A drives the recording pen scanning belt at the rotation speed K2, and also compares the start point signal e1 with the synchronization signal d2, and determines the start point of the calligraphy signal r2 in the detection signal c2 by means similar to the conventional method. The recorder 7B is driven so that it comes to the intended recording start point on the recording paper 71B.

The synthesis circuit 10 supplies the recording pen with a calligraphy signal r1 based on the output signal h1 of the converting means 9A and a calligraphy signal r2 based on the output signal h2 of the converting means 9B having the same configuration as the converting means 9A.

The recording device 7B has a recording pen (not shown) on the recording paper 7.
The one to be recorded first in order to simultaneously scan and record two calligraphy images 72b and 72c in parallel on 1B, that is,
When the starting point of the first recording scan is reached, the starting point detection means 8A outputs the known point signal e1, and when the next recording is reached, that is, the second recording scan is reached, the intermediate point is output. The point detection means 8B outputs an intermediate point signal e2.

That is, the recorder 7B outputs a start point signal e1 corresponding to the start position of the calligraphy image 72b based on the calligraphy signal r2 which is recorded and scanned in the first order, and an intermediate point signal corresponding to the start position of the calligraphy image 72c based on the document image 72c which is recorded and scanned in the subsequent order. I am getting e ₂ .

In the above operation, the time during which the recording pen of the recorder 7B records and scans the width of the calligraphy image 72b and the time period of the calligraphy signal r2 in one cycle T2 of the detection signal c2 are made to approximately coincide temporally. Ori,
It goes without saying that the time taken by the recording pen to record and scan the width of the calligraphy image 72c and the time for sequentially reading out the calligraphy data from the buffer memory 94 in the converting means 9A are almost made to coincide temporally. stomach.

As can be seen from the above explanation, station setting circuit 4C
Frequencies f1, f2 and rotation speed K set by
1 and K2 are set in either of the receiving circuits 3A and 3B, the slower one of the rotational speeds K1 and K2, that is, the scanning speed for the slower one, is always selected and the driving circuit 6A will perform recording scanning.

[Transformation implemented]

This invention can be modified and implemented as follows.

(1) By exchanging the starting point signal e1 and the intermediate point signal e2, the preceding calligraphy image 72b and the succeeding calligraphy image 72c are exchanged.

(2) Single-station setting means that switches so that only one of the signals h1 and h2 is input to the synthesis circuit 10 by the single-station detection means 13 that detects that only one receiving frequency is set. 11
The received calligraphy image of one station is recorded on the entire width of the recording paper 71B by interlocking with the speed change means 12 which halves the reading speed of the conversion circuit or doubles the scanning speed of the recording pen of the drive circuit. indicate.

That is, for example, only the calligraphy image 72b is displayed in a width equal to the sum of the width of the calligraphy image 72b and the calligraphy image 72c.

(3) The one-station detection means, the one-station setting means, and the speed change means described in (1) above are performed by the CPU used as the speed change means.

(4) Change the configuration of the drive circuit and recording circuit to a multi-needle electrode type recorder.

(5) The CPU used in the conversion means performs a discrimination detection process for selecting the lower rotation speed K2 in the station setting means.

(6) One CPU is used for each conversion method.
Let it be done by.

〔Effect of the invention〕

According to the present invention, as described above, since the scanning speed corresponding to the slower calligraphy transmission speed among the facsimile signals being received becomes the selected recording scan, each facsimile signal being received is If you are receiving a combination of fast and medium speeds, you can record and display at a medium scanning speed, and receive a combination of fast or medium speeds and slow transmission speeds. It has the advantage of being able to perform recording and displaying that is adaptive to combinations of document and image transmission speeds, such as recording and displaying at a slow scanning speed only when combined with other documents.

In addition, the rotational speed K set in the station setting means 4C
If 1 and K2 have the same speed, that is, if facsimile signals with the same document image transmission speed are received, the operation is made to select one of the rotational speeds K1 and K2. It is self-evident that it should be done, and there is no need to explain it.

In addition, it is possible to interchange and display the preceding and subsequent document images by simply exchanging the start point signal and the intermediate point signal with a simple configuration and operation. It has the advantage of being extremely convenient for the user, as it is possible to change the records and display them according to the purpose with a simple operation even in the middle of the process.
