Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a facsimile communication system comprising a drawing information transmitting device and a drawing information receiving device that receives and records the drawing information transmitted from the transmitting device.

In conventional facsimile communication systems, when transmitting calligraphy information, the so-called sender information that indicates who and where the sender is is the document (hereinafter sometimes referred to as manuscript) that contains the calligraphy information to be transmitted. This information is written manually or printed in advance in the margin of the tip of the computer, and the transmitting device reads and transmits the information, and the receiving device receives and records the sent source information. Ta. However, in this method of transmitting and receiving source information, it is too cumbersome for the sending side to take the trouble of manually writing the source information on the transmitted manuscript, and it is also a hassle to write the source information on the manuscript paper in advance. Even if you print out this kind of sender information, you may not always use the paper with this kind of sender information printed on it to create the document to be sent, so you can print the sender information. The situation was quite inconvenient regarding sending and receiving. This invention was made in consideration of the conventional inconvenient circumstances as described above.Therefore, the purpose of this invention is to:
Even if there is no sender information written on the side of the transmitted document, the sender information is created separately in the sending device, and is selectively switched with calligraphy information and sent automatically, and the receiving device receives this calligraphy information and To provide a facsimile communication system in which sender information is uniformly received and recorded without distinction, thereby allowing a receiving side to know the sender.

The main points of the structure of this invention are as follows.

That is, in a facsimile communication system consisting of a transmitting device and a receiving device, the calligraphic information obtained by scanning a document, the creation of source information provided in the transmitting device, and the source information automatically sent from the sending device are sent to the receiving device. The main point is that the reception record can be recorded without requiring any additional functions. Next, an embodiment of the present invention will be described in detail with reference to the drawings.

FIG. 1 is a block diagram showing the concept of this invention.

In FIG. 1, the calligraphic information transmitting device TR and the receiving device RE
are coupled by a transmission path 16, the transmitting device TR includes a character memory 2, a character generator 1, a reading scanning head 27, a changeover switch 14, and a transmitting side data processing circuit 15T, and the receiving device RE includes a receiving side data processing circuit 15T. It includes a side data processing circuit 15R and a recording head 17. Now, in the facsimile communication system according to the present invention, the transmitting device is equipped with a sender information sending device, and the receiving device only needs to be equipped to receive and record the transmitted calligraphic information normally, and the type of the receiving device It is distinctive in that it does not ask.

That is, in the transmitter TR, the scanning head 27
The calligraphic information obtained by reading and scanning the transmission document is transmitted via the switch 14 to the transmission side data processing circuit 15T after undergoing ordinary data processing such as storage in a buffer, data compression, and modulation. On the other hand, the source information stored in the character memory 2 as a character code is converted into a pattern code in the character generator 1, and then sent to the data processing circuit 15T via the changeover switch 14. , the calligraphic information and characters read by the reading scanning head 27 are sent to the transmission path 16 after being subjected to exactly the same processing as the calligraphic information. It is not a switch that is switched to send the sender information to the receiver. Control of the size of the font when recording the sender information, control of the recording position on the recording medium, and all other controls related to the sender information are on the sender side. After being sent to the transmission path 16, the source information is received by the receiving device RE in exactly the same way as the calligraphic information, and the data processing circuit 15R on the receiving side performs demodulation, data expansion, storage in a buffer, etc. After being processed, it is recorded by the recording head 17.As the receiving device RE, there is no need for any special device for receiving and recording the sender information, and any ordinary calligraphic information receiving device is sufficient. , the character generator 1 is removed from the transmitting device TR and the character generator 1 is removed from the receiving device R.
In preparation for E, it is conceivable to transmit source information in the form of a character code through the transmission line 16; It is not a good idea because it is necessary to identify whether it is information and apply different data processing accordingly, which complicates control. As explained above, in the facsimile communication system of the present invention, the receiving device may be of any type and type, but an example of the receiving and recording device is shown in FIG. 2, and the document information reading scanning head in the transmitting device is also An ordinary one may be used, and an example is shown in FIG. Second
3 will be briefly explained. See Figure 2.

The carriage 18 is loosely inserted into a guide shaft 21 supported by a side plate of the device (not shown), and is connected to the carriage 18 via a wire 22 and a pulley 23, both ends of which are respectively fixed to the carriage 18.
A drive motor 24 such as a servo motor rotates forward and backward to reciprocate on the guide shaft 21. This moving direction is a main scanning direction orthogonal to the sub-scanning direction, which is the moving direction of the recording paper P. The recording head 17 mounted on the carriage 18 is
It moves back and forth together with the carriage 18, and during this forward movement, records are sent to the recording paper P. An electrode needle 17a is provided at the upper end of the recording head 17 with its end exposed. The recording head 17 moves in the main scanning direction with the recording paper P in contact with the upper end of the recording head 17, and the electrode needle 1
An electrostatic latent image is formed on the recording paper P by means for applying a signal voltage by a discharge action between 7a and an auxiliary electrode (not shown), and then developed by means (not shown). Note that the detection unit 31 fixed to the upper surface of the carriage 18 is provided with a photo sensor 31a at the upper stage and a photo sensor 31b at the lower stage. These photosensors face a light source (not shown) through a slit pattern 19 made of a film or an etched plate, and form two sets of photocouplers. In the slit pattern 19, a large number of slits 19a are arranged side by side at intervals equal to the linear density pitch in the main scanning direction during recording. As the carriage 18 moves in the main scanning direction indicated by the arrow, the recording head 1
7. The detection member 31 moves together with the carriage 18, and at this time the slit pattern 19 does not move and remains at a fixed position. Therefore, a photocoupler consisting of the lower photosensor 31b of the detection member 31 and a light source (not shown) sequentially reads the slit marks 19a of the slit pattern 19, and uses the clock pulses obtained thereby as drive pulses to drive a control circuit (not shown). The recording head 17 performs recording through the recording head 17. Note that a photocoupler consisting of the upper photosensor 31a of the detection member 31 and a light source (not shown) is
It is used to read the start mark 19s and end mark 19e of the slit pattern 19, and the start mark 19s and end mark 19e indicate the effective recording width of the recording paper. The received document image information is converted from serial to parallel signal array in the shift register 20 using X and Y clock signals from the read/write buffer shown in the figure, and converted into a drive signal in the recording converter 25. Thereafter, the voltage is supplied to the recording head 17. See Figure 3.

Figure 3A shows a perspective view of a conventional reading scanning head;
Figure o shows a cross-sectional view of the head along the line x--x and a block diagram of the associated circuitry. The reading of transmission document 0 by the reading head 27 is performed as follows.
The document 0 is conveyed by a pair of conveying rollers 28 and 29 in the sub-scanning direction indicated by the arrow. On the other hand, the head 27 mounted on the carriage 18 is reciprocated along the guide shaft 3 by a servo motor (not shown) in the same manner as the carriage 18 shown in FIG. Along with this, we will be traveling back and forth together, and we will conduct scans on our way there. Two light source lamps 3 provided at the front end of the head 27
The light from 2 is reflected on the document surface through target glass 33, and this reflected light is condensed through lenses 34 and 36 and projected onto photodiode array 12. The video signal read in this manner is amplified by an amplifier 36, then binarized by a threshold circuit 37 and output. Next, the source information creation and transmission circuit provided in the transmitter will be described in detail. FIG. 4 is a block diagram for explaining the concept of the character generator, and FIG. 5 is a block diagram illustrating part of the memory contents of the character generator.

1 indicates a character generator.

Please refer to FIGS. 4 and 5. FIG. 4 is a diagram for explaining the operation of the character generator 1 that generates the pattern code of the alphanumeric character.
Assume that the character designation code input from the left input terminal of the character generator 1 is a code designating the character F. In the character generator 1, for example, as shown in FIG.
, to IJ', which has a memo with the address of a snake, contains a memorized pattern of the letter F. It is assumed that the black section portion represents a logic 1 signal and the white section portion represents a logic 0 signal. When the character F is designated by the character designation code, a memory as shown in FIG. 5 is designated in the character generator 1, and a switching signal input separately to the x data switching terminal E of the character generator 1 causes Pattern codes of the letter F are sequentially output in parallel from the right y to y8 lines. Now, suppose that the pulse signal input to terminal E specifies the position x,
From the y, to y8 lines, each address (x, ,
y, ), (x,, Maki), (×,, y3), . …． (×,
,y7), (×,,y8) data, that is, 0,0,0
, 0, 0, 0, 0, 0 are output in parallel. Next, if a second pulse is applied to each terminal to specify the position of &, then similarly, each address (
Ume, y, ), (x2, y2), (yen, y3), (x2,
y4)... (Sugi, y7), (average, average) data, that is, signals of each value of 0, 0, 0, 0, 0, 0, 0, 0 are output in parallel. Next, suppose that a third pulse input is applied to terminal E to specify the position of the object, then each address (x3, y,), (x3, y2, (x3,
y3)...(x3, y7), (ume, y8) data, that is, signals of each value of 1, 1, 1, 1, 1, 1, 1, 0 are output in parallel. The same applies hereafter. These output data display the letter F when received and recorded on the receiving side. By the way, as is well known, the physical size of one dot recorded on the recording medium of a facsimile receiver is much smaller and difficult to see than that of a general dot printer. Therefore, if a dot printer is used as the reception recording means, a sufficiently large and easy-to-read character record can be obtained even if one dot sent from the character generator is treated as one dot. When receiving and recording on a device, the font size becomes very small and difficult to read. Therefore, for each dot generated from the character generator,
If a facsimile receiver records N (N>1) dots of the same signal content, the character size will be enlarged, making it easier to read. In this way, for every 1 dot from the character generator, N dots are sent to the facsimile receiver, so due to some reason such as a failure, some of the N dots may be lost during transmission. Even if some dots appear, the probability that all dots will be missing is low, which ultimately increases the reliability of the received record. FIG. 6 is a block diagram showing an example of a source information creation and transmission circuit.

In FIG. 6, 1 is a character generator, 2 is a character memory group, 3 is a character counter, 4 is a row counter, 5 is a column counter, 6 is a multiplexer, 7 and 7a are horizontal multipliers, and 8a are each Vertical multiplier, 9 and 10 are selection switches, A is add gate,
0 represents an OR gate, NA represents a NAND gate, FF represents a flip-flop, and Vcc represents a power supply voltage. Please refer to FIG.

First, a rough outline of the configuration and operation will be explained. The X clock signal is a main scanning data sampling clock signal, and the Y clock signal is a fast scanning data sampling clock signal. The X clock signal is applied as an X data switching pulse to the row counter 4 via the AND gate A4 from the horizontal multipliers 7 and 7a, or the AND gate A5 from the horizontal multiplier 7, and the OR gate 02.
The row counter 4 counts the pulses and converts the character switching pulse to a character every time the pulse reaches one character.
Send to counter 3. The character counter 3 counts character switching pulses, sequentially designates addresses in the memory group 2 using the count output value, and the character code existing at the address is read from the memo IJ group 2 and is sent to the character generator. Sent to 1. As previously explained with reference to FIGS. 4 and 5, the character generator 1 receives the x data switching signal output by the row counter 4 by counting the X data switching pulses, and generates the pattern of the character.・Generates a code. The multiplexer 6 converts the parallel pattern code signal from the character generator 1 into a serial signal under the control of the column count output signal output by the column counter 5 receiving and counting the Y clock signal from the OR gate 01. It is converted and output to AND gate A6. In the memory group 2, predetermined source information is stored in a predetermined address order, which is sequentially read out under the control of the character count 3, converted into a pattern code by the character count generator 1, It is sent to the receiving side via multiplexer 6, AND gate A6, and OR gate 03. Selection switch 10
depends on whether it is on the Vcc side or the earth side.
This is a switch that controls the enlargement rate of character size when recording sender information on the receiving side. The selection switch 9 is used to select whether to send sender information each time each page of the document is sent, or to
This is a switch to select whether to send only when a page is read and sent. Note that the blueprint information obtained by scanning the document is transmitted via the AND gate A7 and the OR gate 03 after being selectively switched with the source information. FIG. 7 is a time chart showing signal waveforms of various parts during operation of the circuit shown in FIG. 6.

Next, the operation of this source information creation and transmission circuit will be explained in more detail with reference to FIGS. 6 and 7, but before that, the configuration of the photodiode array included in the Kettori scanning head will be explained. .

FIG. 8 is a diagram showing the array, where 12 represents a photodiode array and 13 represents a photodiode element. The array 12 is made up of, for example, 32 photodiode elements 13 arranged in a line in the vertical direction, and when scanning document and image information, the 32 photodiode elements 13 are arranged in a sub-scanning direction, which is the moving direction of the document. will be placed in Then, 32 sub-scanning clock pulses (Y clock signals) that sequentially excite each element 13 are generated in order, and when all 32 photodiode elements have been excited, the array 12 is then activated in the main scanning direction by the main scanning clock pulse (Y clock signal). X clock signal), and then each photodiode element performs scanning in the sub-scanning direction. In other words, in this short scanning method, one main scanning clock pulse (X clock signal) is generated for every 32 sub-scanning clock pulses (Y clock signal). The above-mentioned Kendori scanning method is just one example; for example, photodiodes or the like are arranged in a row or in a staggered manner in the main scanning direction to read the calligraphic information, and the original is conveyed to perform sub-scanning. Of course, it will be understood that a standard reading method may be used.

Now, in FIG. 6, when a transmission start signal (FIG. 7a) is sent from the system control unit (not shown) and sets the flip-flop FFI, the set output passes through the AND gate AI and becomes a character.
The counter 3, the row counter 4, and the column counter 5 are added to start operation (assuming that the selection switches 9 and 10 are both switched to the power supply voltage Vcc side as shown).

The X clock signal (Fig. 7b) sent out at the start of the main scan of the Suzuko head passes through the horizontal multipliers 7 and 7a, the AND gate A4, and the OR gate 02, and the X data switching pulse (Fig. 7E or 8) is input to the row counter 4 and counted. The horizontal magnifiers 7 and 7a are each
In this case, it is a stepper that lowers the pulse frequency by half. In the present example, the x clock signal is transmitted to two telescopes 7.
, 7a, the pulse frequency is eventually stepped down to 1/4 and becomes the X data switching pulse (FIG. 7E). In other words, ×4 clock signals (main scanning clock pulses),
In other words, by sustaining the same dot output from the character generator 1 for four dots of the calligraphic information transmitting device, the dot size of the character code is expanded four times. Note that if the selection switch 10 is switched to the earth side, the band gate A4 is closed and the gate A5 is opened, so that after the X clock signal passes through the horizontal multiplier 7,
7a, passes through AND gate A5, passes through OR gate 02, and reaches row counter 4, so in this case, the dot size of the character code is doubled. FIG. 7E shows a case where the image is enlarged four times. Now, the row counter 4 is configured to send one character switching pulse (FIG. 7F) to the character switching pulse every time it counts eight X data switching pulses. This is because, as shown in FIG. 5, one character is made up of eight dots in the row direction. In addition, in FIG. 7, 8 is a scaled-down representation of the waveform of E. Each time the character counter 3 receives and counts a character switching pulse from the row counter 4, it sequentially designates addresses in the memory group 2 according to the new count value. In other words, source information is read out character by character from the memory group 2 to the character generator 1 in the form of a character code at addresses sequentially specified by the character counter 3.
The character generator 1 sends pattern codes for the character codes read from the memory group 2 to the multiplexer 6 in parallel row by row under the control of the x data cutoff signal from the row counter 4. . The multiplexer 6 serializes this parallel signal and sends it out to the AND gate A6, but this sending out of the serial output is performed under the control of the count output of the column counter 5. Y clock signal (
Fig. 7C) can be divided into 1/4 by passing through vertical magnifiers 8, 8a, which are exactly the same as the horizontal magnifiers 7, 7a described above.
It passes through AND gate A2 and OR gate 01, and becomes the Y data switching pulse (FIG. 7D). Note that when the selection switch 10 is switched to the earth side, AND gate A2 is closed and A3 is opened, so that the Y clock signal is downgraded to 1/2 the pulse frequency by the vertical multiplier 8 only, and the Y clock signal is This becomes a data switching pulse. Y
The data switching pulse is input to the column counter 5 and counted. According to the count value, multiplexer 6
In , the column of character pattern signals is advanced, and the dot output of the signal is vertically enlarged by a factor of 4 or 2 and sent as a serial output to the AND gate A6. When all output codes from memory group 2 are logic 1, this is called a character prohibition signal,
Transmission of sender information is prohibited, and calligraphy information is transmitted.

In other words, the character prohibition signal is the NAND gate NA1'
Therefore, a logic 0 is detected from the NAND gate NAI.
is applied to one input side of the NAND gate NA3. Therefore, the output of NAND gate NA3 is always logic 1.
Therefore, since the AND gate A6 is closed, the sender information is not transmitted, and since the AND gate A7 is opened, the calligraphy information is transmitted via the OR gate 03.
In addition, when the selection switch 10 is connected to the Ikei side, when the column counter 5 completes 8 counts and information for one character is sent from the multiplexer 6, the column counter 5 outputs the information from the NAND gate at the next count. The output to NA2 becomes logic 1, and therefore both inputs of NAND gate NA2 become logic 1 signals, so the output of NAND gate NA2 becomes logic 0, and therefore the output of NAND gate NA3 becomes logic 1, and AND gate A6 closes, so no transmission occurs. Sending out the original information is prohibited, and on the other hand, since the band gate A7 is opened, sending out the calligraphy information is allowed. This means that when the selection switch 10 is switched to the power supply voltage Vcc side, the dot recording dimensions on the facsimile receiver side are 4 times the horizontal magnification and 4 times the vertical magnification.
However, when the selection switch 10 is switched to the earth side, the size of the dot recording on the receiving side is 2 times the horizontal magnification and 2 times the vertical magnification. Since it is only doubled, or quadrupled in character area, there should be extra space on the recording medium that can be recorded, and the calligraphic information can be sent to that space to make it possible to record it. It's for a reason. The flip-flop FFI is reset by the unit scan end pulse that is generated every time one main scan ends and the document moves by a unit distance in the sub-scan direction. Everything is reset and ready for the next operation.

In the above example, the unit scan end pulse is generated every time one main scan ends, but it is not limited to one time. In the Kendori method where the documents are arranged in a line or in a staggered manner, the document must be generated after the document has been fed by a predetermined amount. With calligraphy information transmitting devices, there are cases where manuscripts are transmitted continuously over multiple pages, but in this case, there are cases where you want to send sender information only when reading and transmitting the first page, and cases where you want to transmit sender information only when reading and transmitting each page. There are cases where you want to always send sender information every time.

In the former case, the selection switch 9 is switched to the continuous transmission number side, and in the latter case, the selection switch 9 is switched to the power supply voltage Vc.
All you have to do is switch to the c side. The continuous transmission signal is generated from a system control unit (not shown), and is at a high level only during the scanning of the first page, and from the second page onwards, it is at a low level and the AND gate AI is activated.
, counters 3, 4, and 5 cannot operate from the second page onwards. On the other hand, if the selection switch 9 is switched to the power supply voltage Vcc side, the AND gate AI is always open, so each counter 3,
4 and 5 can operate and send out origin information for each page. Note that when reading and transmitting multiple pages of a manuscript continuously, sender information is sent only for the first page, and when reading and sending a single page, sender information is sent for each page. If you want to switch automatically, you can do as follows.
That is, the circuit S in the dotted line surrounding the selection switch 9 in FIG. 6 may be replaced with the circuit S in the dotted line in FIG. 6a. See Figure 6a.

When reading and transmitting one page at a time,
System controls not shown at the beginning of the transmission operation
An initial reset signal is supplied from the unit, so if flip-flop FF2 is reset in response to this signal, its Q output becomes logic 1, so the AND gate AI is opened and the source information is reset as explained above. Can send.

On the other hand, when reading and transmitting continuously over multiple pages, a multipage detection signal is obtained from the system control unit at the start of transmission of the second page, so if flip-flop FF2 is set using this signal, its Q output is now a logic 0 and the AND gate AI is closed. Therefore, as already explained, after the sender information for one page is sent, no sender information is sent thereafter. FIG. 9 is a detailed circuit diagram of the memory group 2, character generator 1, multiplexer 6, etc. in FIG.

In FIG. 9, 2a is a decoder, 2A to 2D are character memories, IA and IB are character generators, and 6A and 6B are multiplexers. See FIG. 9. The two outputs from the character counter 3 are applied to a decoder 2a which selects one of the four character memories 2A to 2D and selects the selected memory, e.g.
A chip enable signal CE is sent to A. Another output from the character counter 3 specifies an address in the memory, and the character code for that address in the memory 2A is read out and sent to the character generator (IA).
or IB). The selection of character generator IA or IB is determined by whether a logic 1 signal is applied to its chip select terminal cs. Now, decoder 2a
Assume that the memory 2A is selected and a certain address in the memory 2A is designated by the character counter 3. However, there are cases where the memory itself is attached to the address and is not there. At this time, all the read outputs of the address are set to logic 1 by the action of the pull-up resistor R whose one end is connected to the power supply voltage VCC. Therefore, the NAND gate NAI generates a character prohibition code detection signal, prohibiting transmission of source information, and instead enables transmission of calligraphic information. This means that if character memory is installed, and if there is no character memory, there is no source information to be transmitted. This makes it possible to record data on a recording medium, and has the effect of enlarging the effective screen on the recording medium. FIG. 10 shows a perspective view of the character memory mounting section, and FIG. 11 shows the format of the character memory.

In FIG. 10, 2AS to 2DS each indicate an IC socket for attaching a character memory. Please refer to FIG.

Character memories 2A to 2D are attached to IC sockets 2AS to 2DS configured on the board, respectively, but only memory 2C is attached in the figure. The number of characters for one line that can be recorded on the receiving side recording medium is divided and stored in, for example, four character memories 2A to 2D. If the source information covers the entire width of one line of the recording medium, it is necessary to store the source information in four sets of memories, but such cases are rare. 1/ for one line
If 4 is enough, it is sufficient to store the source information in any one memory, and in this case, the other memories do not need to be attached to the IC sockets on the board.

In addition, the positions of the four IC sockets correspond to the position of one line of the recording medium, so even if the same character memory is used, the recording position on the recording medium will depend on which IC socket it is installed in. It's going to change. Please refer to FIG.

The format of the character memory is that for each address, bits 1 to 6 are character specification codes, the 7th bit is a bit for selecting character generator IA or IB, and the 8th bit is whether to send source information or print information. This bit is used to select whether to send the . Note that it is convenient to store character patterns such as alphabets and numbers in the character generator IA, and to store character patterns such as kana in the character generator IB. In Japan, a single source information may require both alphabetic and kana characters. For example, a company's name may be written in alphabetical letters, and its location may be written in kana. In such a case, a cluster of two character generators can be provided. As described above, according to the present invention, even if the sender information is not written in the transmitted document, the sender information separately stored in the memory can be read using the scanning clock signal of the reading head. It can be sent automatically to the other party, and the size of the characters, positional relationship, and type of characters when recording can be controlled by the sender. Furthermore, in the case of continuous transmission over multiple pages, sender information can be sent for each page. It includes a calligraphic information transmitting device that has a wide variety of functions, such as being able to select whether to send out a page or only to a specific page, and the receiving device for this can be an ordinary device that does not require any special additional functions. , an easy-to-use and convenient facsimile communication system that can be used in any format or type is provided.
