DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a facsimile device that transmits management information, which is information that should be managed on a sending side, and in particular, information indicating the date and time of transmission, together with image information of a document.

BACKGROUND TECHNOLOGY If the sending side cannot generate information that should be managed by the sending terminal, especially the date and time of transmission, and the name of the sending terminal, the receiving side cannot know where the received document was sent from or what time it was sent. It is difficult to determine whether In order to clarify these matters, the sender had to go to the trouble of attaching a cover letter containing the above-mentioned management information before sending the manuscript, or had to contact the recipient directly by telephone or the like.

In order to solve these problems, a technique has been proposed in which management information is created before transmitting the manuscript, and the created management information is transmitted together with the image information of the manuscript.

Problems to be Solved by the Invention However, in the above-mentioned proposed technology, the image information of the manuscript is developed in the transmission memory etc. after the management information is created, so the actual transmission of the manuscript is not carried out after the management information is created. There was a slight lag in time until it arrived. In particular,
If the processing speed of the CPU is slow, the difference in required time will become large.

The present invention has been made to solve the above-mentioned problems, and an object of the present invention is to provide a facsimile device that can display accurate transmission date and time on reception recording paper.

Means for Solving the Problems In order to achieve the above-mentioned object, the present invention includes a timer that counts the value of the transmission date and time as variable information every moment, and specifies the transmission date and time by combining the numerical value of the timer and the count value of the timer. A kanji ROM that stores a fixed pattern of kanji characters, etc. to be displayed, and management information including a character string generated by combining the counted value of the time measuring means and the stored content of the kanji ROM, and then reads the manuscript. a storage means for successively storing the image information obtained through the process; writing to the storage means is performed in the order of the image information and the management information; and reading from the storage means is performed in the order of the management information and the image information; and control means for performing and transmitting the information.

Effects With the above configuration, the present invention can minimize the time from generation to transmission of variable information indicating the transmission date and time (numerical value of the transmission date and time) included in the management information, and as a result, the receiving side record Information indicating accurate transmission date and time can be recorded on paper.

Embodiment Below, as an embodiment of the present invention, a facsimile terminal device that realizes the above functions will be shown and explained in detail.

FIG. 1 shows a block diagram of an embodiment of a facsimile terminal device. In a conventional facsimile, when transmitting, image information scanned by a reading unit 1 is encoded in a band compression unit 4 to reduce redundancy and transferred to a transmission control unit 5, where a synchronization signal for each line is transmitted. is added, and then transmitted through the line control section 6, which includes a modem and a network control device. In the case of reception, on the other hand, a synchronization signal is detected through the line control section 6 and transmission control section 5, and is restored by a band expansion section (not shown) to become a signal equivalent to the read original, and is recorded in a recording section (not shown). be done. The system control unit 7 controls these sequences.
It is.

In addition to this function, the apparatus of this embodiment has a function of sending information such as communication time, transmitting terminal name, page number, etc. in addition to image information so as to be recorded in the header of the received image. The following explains how this function is achieved.

Fixed pattern of management information (e.g. “Sending terminal =
"XY Division 2nd Warehouse", "Communication time =", "Hello", etc.) are stored in the ROM shown in Figure 1 in advance.
Write it in 3. Buffer memory 2 in Figure 1
can be written from any of the data buses of the CPU included in the bandwidth compression unit 4, ROM 3, and system control unit 7 under the control of the buffer memory control unit 9, and is included in the transmission control unit 5 and system control unit 7.
It can be read by either CPU. That is, as shown in FIG. 2, four bidirectional bus drivers 11 to 14 are connected to the data input/output terminal of the buffer memory 16, and each section can be read and written under the control of the buffer link switching section 10.

As shown in FIG. 3A, the buffer memory 16 has a reserve area A for management information and an area B for image information.
When inputting a document, the value of the address counter 15 is set to the start address of area B. Further, the link designation (hereinafter abbreviated as link designation) as to which block is to be read or written to the buffer memory 16 is initially set to the write state from the band compression unit 4 by the buffer link switching unit 10. That is, in FIG. 2, the bidirectional bus driver 11 is chip enabled.

When a document is input in this state, the image information scanned by the reading section 1 is encoded by the band compression section 4 and written into the area B in FIG. 3A. Upon completion of scanning, by setting the link specification to write from ROM3, the bidirectional bus driver 1 shown in Fig. 2
2 becomes the chip enable and clears the address counter 15 at the same time. In this way, the fixed pattern of management information written in advance in ROM3 is
The data is transferred to the reserve area A of the buffer memory 16. At this point, the contents of the reserve area A of the buffer memory 16 are only a fixed pattern of management information, with the date, time and page number missing, as shown in FIG. 3A. Next, set the link specification to write from the CPU data bus and write the management information.
Write from the CPU to a fixed address in the buffer memory 16. This address indicates a blank part of the fixed pattern of management information shown in FIG. 3A. At this point, the uncompressed management information is stored in the reserve area A of the buffer memory 16 as shown in Figure 3C, and the compressed image information of the input document is stored in the area B. .

Next, the sequence moves to reading from the buffer memory 16. When reading management information, conversion based on linear density is required.

The linear density converter 8 has this function, and its configuration is shown in FIG. In addition, buffer memory 2
It is assumed that the management information within is written at the coarsest linear density of this device.

First, a case where the linear density becomes m times finer in the scanning direction will be described. The management information read from the buffer memory 2 is stored in one line memory 2 for each line.
1 and is transferred to the band compression unit 4 at a predetermined transfer clock. On the other hand, the transfer clock is frequency-divided by 1/m in the counter 18 and the decoder 19 according to the input linear density information, and the 1/m-divided clock is input to the address counter 20. This address counter 20 is a 1-line memory 21
The read and write addresses are specified, and in this case, the read address is specified in accordance with a clock frequency divided by 1/m. In this way, the management information in the 1-line memory 21 is read out in accordance with the transfer clock, and on the other hand, the read address is specified in accordance with the clock obtained by dividing the transfer clock by 1/m. From then on, the same bit is read out m times, resulting in a finer line density in the scanning direction.

Next, a case where the width becomes n times finer in the width scanning direction will be explained. 1 read from buffer memory 2
Management information for a line is transferred to the band compression unit 4 via the selector 24, while one line memory 2
Written to 1. When the address counter 20 detects that writing of one line is completed, the address counter 20 outputs a carry to the counter 22, and as a result, the decoder 23 switches the selector 24 to the one line memory 21 side. Thereafter, the decoder 23 reads the management information from the 1-line memory 21 (n-1) times, and during that time does not read the management information from the buffer memory 2 containing the management information. Note that the decoder 23 is (n-1)
When the address counter 20 and the counter 22 detect the completion of one read, the read from the one line memory 21 is finished, the selector 24 is returned to its original state, and a write instruction is given to the one line memory 21.

The reading sequence using the linear density converter 8 configured as described above is as follows. That is, the link designation is set to read to the band compression unit 4 and the transmission control unit 5 (the bidirectional bus driver 14 in FIG. 2 is set to chip enable), and at the same time, the data input of the transmission control unit 5 is set to the band compression unit 4 side. , and the data input of the band compression section 4 is switched from the reading section 1 to the linear density conversion section 8. Thereby, the management information is subjected to linear density conversion by the linear density converter 8, encoded by the band compressor 4, and transmitted from the transmission controller 5 through the line controller 6. At this time, the management information end detection unit 17 shown in FIG. 2 monitors the address counter 15 and the end address of the reserve area A, stops the transfer clock at the end of the management information transfer, and transfers the data input from the transmission control unit 5 to the buffer memory. 2 side, and the data input of the band compression section 4 is returned to the reading section 1 side. In this way, the transfer is resumed and the buffer memory 1 is
The compressed information of the input document is transferred from area B of 6 to the transmission control unit 5.

In this way, a recorded image is obtained in which the sending side management information is recorded in the received image header.

Effects of the Invention As described above, the present invention writes and reads image information and management information to and from a storage means in the order of image information and management information at the time of writing, and management information and image information at the time of reading. By doing this in the order of the information, the time from the generation of the variable information indicating the transmission date and time included in the management information (the numerical value of the transmission date and time) to the transmission can be minimized, and as a result, the receiving side Information indicating accurate transmission date and time can be recorded on the recording paper.
