Abstract

PURPOSE:To provide the exact record of transmission date and time by performing operations from the generation of variable information to the transmission in a short time by performing write in the order of image information and management information and performing read in the reversed order. CONSTITUTION:At the time of write, the image information scanned by a read part 1 is made into compressed codes by a band compression part 4 and written in a reserve area B of a buffer memory 2. On the other hand, the fixed pattern of management information previously written in a ROM 3 is written without being compressed into a reserve area A. At the time of read, link designation is set to read to the compression part 4 and a transmission control part 5, at the same time, the data input of the control part 5 is set to the side of the compression part 4, and the data input is switched from the read part 1 to a linear density conversion part 8. Thus, the management information in the area A is encoded by the compression part 4 while performing linear density conversion at an exchange part 8 and transmitted from a line control part 6. When the management information is completely transferred, the data input of the control part 5 is turned to the side of the buffer 2, the data input of the compression part 4 is turned to the side of the read part 1, transfer is started again, and the compressed information of an input original is transferred from the area B.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a facsimile apparatus for transmitting management information, which is information to be managed on the transmitting side, and in particular, information indicating a transmission date and time together with image information of a document.

[0002]

2. Description of the Related Art When information to be managed by a sender terminal, especially the date and time of sending and the name of the sender terminal cannot be generated on the sender side, the receiver side determines where the original was sent from, or at what time. It is difficult to determine whether it is the correct one. In order to clarify these matters, the sender has to bother to attach a delivery note in which the above management information is described before sending the manuscript, or to directly contact the recipient by telephone or the like.

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

[0004]

However, in the above-mentioned proposed technique, since the image information of the manuscript is expanded in the transmission memory after the management information is created, the manuscript is actually sent after the management information is created. There was a slight time lag until. Especially, the CP in the facsimile machine
When the processing speed of U becomes slow, the deviation of the transmission time becomes large.

The present invention has been made to solve the above problems, and an object of the present invention is to provide a facsimile apparatus capable of recording an accurate transmission date and time on a reception recording paper.

[0006]

In order to achieve the above object, the present invention converts clock information, which is variable information, of transmission date and time, and converts the data output from the clock means into numerical information. First output means for outputting at a predetermined scanning line density, second output means for reading a document and outputting image information of the document at the read scanning line density, and the outputted numerical information and the image information. And a storage means for synthesizing and storing the same, and writing to the storage means in the order of the image information and the numerical value information, while reading from the storage means performs the numerical information and the image information in that order and transmits. And a control means.

[0007]

According to the present invention, with the above configuration, the time from generation to transmission of the variable information (numerical value of transmission date and time) indicating the transmission date and time included in the management information can be shortened.
As a result, it is possible to record the information indicating the correct transmission date and time on the receiving side recording paper.

Further, since the management information is output at a predetermined scanning line density and is written in the storage means, it is possible to generate the management information with a simple structure.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS As a preferred embodiment of the present invention, a facsimile terminal device that realizes the above functions will be shown and described in detail below.

FIG. 1 shows a block diagram of an embodiment of a facsimile terminal device. In the conventional facsimile, when transmitting, the image information scanned by the reading unit 1 is encoded by the band compression unit 4 to reduce the redundancy and transferred to the transmission control unit 5, where the synchronization signal for each line is transmitted. After being added,
It is transmitted through the line controller 6 including a modem and a network controller. On the contrary, in the case of reception, the line control unit 6 and the transmission control unit 5
Through, a synchronization signal is detected, and becomes a signal equivalent to the original read and restored by a band expansion unit (not shown),
It is recorded by a recording unit (not shown). The system controller 7 controls these series of sequences.

In addition to this function, the apparatus of the present embodiment has a function of transmitting the image information in addition to the image information so that the communication time, the transmitter name, the page number, etc. are recorded in the received image header. The following describes how this function is realized.

[0012] fixed pattern of the management information (e.g., "transmitting terminal = XY Division second warehouse" and "communication time =" and "Hi", etc.), Prefer written to ROM3 previously shown in FIG. The buffer memory 2 of FIG. 1 can be written by any of the band compression unit 4, the ROM 3, and the CPU data bus included in the system control unit 7 under the control of the buffer memory control unit 9, and the transmission control unit 5 and the system control unit Reading is possible to any of the CPUs included in the unit 7. That is, as shown in FIG. 2, four bidirectional bus drivers 11 to 14 are connected to the data input / output of the buffer memory 16 so that reading and writing can be performed for each section 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 an original, the value of the address counter 15 is the start address of the area B. Is set to. Further, a link designation (hereinafter, abbreviated as link designation) which block is to be read or written in the buffer memory 16 is initially set by the buffer link switching unit 10 to a writing state from the band compression unit 4. . That is, in FIG. 2, the bidirectional bus driver 11 is chip-enabled.

When an original is input in this state, the reading unit 1
3 is encoded by the band compression unit 4, and the image information scanned in FIG.
A is written in the area B. By setting the link designation to write from ROM3 when scanning is completed,
The bidirectional bus driver 12 of FIG. 2 becomes chip enable, and at the same time, the address counter 15 is cleared. In this way, the fixed pattern of the management information prewritten in the ROM 3 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 in the state shown in FIG. Next, the link designation is set to write from the CPU data bus, and the management information is written from the CPU to a predetermined address in the buffer memory 16. At this time, the management information in the uncompressed form is stored in the reserve area A of the buffer memory 16 as shown in FIG. 3C, and the image information of the input original in the compressed form is stored in the area B. .

Next, the sequence for reading from the buffer memory 16 is started. When reading the management information, conversion by the linear density is necessary.

The linear density conversion unit 8 has this function, and its configuration is shown in FIG. The management information in the buffer memory 2 is written with 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 the 1-line memory 21 for each line and transferred to the band compression unit 4 at a predetermined transfer clock. On the other hand, in the counter 18 and the decoder 19, the transfer clock is divided by 1 / m according to the input linear density information, and the 1 / m divided clock is input to the address counter 20. The address counter 20 specifies the read / write address of the 1-line memory 21,
In this case, the read address is designated according to the clock divided by 1 / m. As described above, the management information in the 1-line memory 21 is read according to the transfer clock, while the read address is specified according to the clock obtained by dividing the transfer clock by 1 / m. Therefore, the same bit is read m times, resulting in a finer line density in the scanning direction.

Next, description will be made on the case where the image becomes finer by n times in the sub-scanning direction. The management information for one line read from the buffer memory 2 is passed through the selector 24 to the band compression unit 4
While being transferred to, the data is written in the 1-line memory 21. 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 1-line memory 21 side. After that, the decoder 23 reads the management information from the 1-line memory 21 (n-1) times, and does not read it from the buffer memory 2 containing the management information during that time.
When the decoder 23 detects the completion of (n-1) times of reading from the address counter 20 and the counter 22, the decoder 23 finishes the reading from the 1-line memory 21, restores the selector 24 to the original state, and the 1-line memory. 21
Write to.

The reading sequence using the linear density conversion unit 8 thus constructed is as follows. That is,
The link designation is set to read to the band compression unit 4 and the transmission control unit 5 (chip enable of the bidirectional bus driver 14 in FIG. 2), and at the same time, the data input of the transmission control unit 5 is set to the band compression unit 4 side. The data input of the band compression unit 4 is switched from the reading unit 1 to the linear density conversion unit 8. As a result, the management information is linearly density-converted by the linear density converter 8, then encoded by the band compressor 4, and transmitted from the transmission controller 5 to the line controller 6.
Sent through. At this time, the management information end detection unit 17 of 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 transfer of the management information, and transfers the data input of the transmission control unit 5 to the buffer memory 2 And the data input of the band compression unit 4 is returned to the reading unit 1 side. In this way, the transfer is restarted, and the compression information of the input document is transferred from the area B of the buffer memory 16 to the transmission control unit 5.

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

[0021]

As described above, according to the present invention, the operation of writing and reading the image information and the numerical information of the transmission date and time to the storage means is performed in the order of the image information and the numerical information at the time of writing, and at the time of reading. By performing the numerical information and the image information in this order, the time from the generation of the variable information (the numerical value of the transmission date and time) indicating the transmission date and time to the transmission can be performed in the shortest time. It is possible to record the information indicating the accurate transmission date and time on the recording paper. Further, since the numerical information is output at a predetermined scanning line density and this is written in the storage means, it is possible to generate the numerical information with a simple configuration.
