Description

DETAILED DESCRIPTION OF THE INVENTION The present invention records information to be managed by the transmitter on the reception record surface, such as the transmitter number and information indicating the user who used the transmitter. The present invention relates to a facsimile machine that adds this information to image information and transmits the information.

With conventional facsimile machines, the display of information managed by the communication partner terminal is limited to line density, transmission speed, terminal number,
Phase B to check functionality with the other device model before image information transmission
The method used has been to check the control procedure at the point in time and display it on the operation panel.

However, regardless of the basic transmission speed and linear density, the exchange of terminal numbers cannot be achieved without the ability to exchange terminal numbers between mutual terminals, and management of the partner terminals includes a wide range of other functions other than terminal numbers. The disadvantage is that it requires information to

The present invention solves the above-mentioned conventional drawbacks, and at the transmitting side,
In Phase C of image information transmission, these various management information are added to the image information and sent, and various information managed by the sending side is recorded on the recording surface regardless of the functions of the other party's terminal, and the information to be recorded is This type provides a facsimile machine that can be easily adapted by changing only the sending side. DESCRIPTION OF THE PREFERRED EMBODIMENTS As embodiments of the present invention, a facsimile terminal device, a facsimile device with a built-in sequential broadcasting device, and a facsimile distribution device that realize the above functions will be shown and explained in detail below.

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 is transferred to a transmission control unit 5.
After adding a synchronization signal for each line, the signal is transmitted through the line control section 6 including 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 unit 6 and transmission control unit 5, and is restored by a band extension unit (not shown) to become a signal equivalent to the read original and recorded in a recording unit (not shown). Ru. The system control unit 7 controls these sequences.

In addition to this normal function, the facsimile apparatus of this embodiment has a function of transmitting, in addition to image information, communication time, transmitting terminal name, and page to be recorded in the received image header when transmitting.

An embodiment of the present invention will be described below with reference to FIG.

When a normal sequential broadcast device sends the same document to multiple destinations,
In order to avoid inputting and transmitting documents to each address one by one, it has a buffer memory for at least one page, stores image information there, and has the function of sequentially transmitting it to specified destinations.

That is, in FIG. 3, image information scanned by the reading section 1 is encoded by the band compression section 4 and stored in the buffer memory 2. Each time it is connected to a designated destination terminal, it is transmitted through the transmission control section 5 and the line control section 6. The system control unit 7 controls these sequences.

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

Fixed patterns of management information (for example, "Sending terminal = XY Division 2nd Warehouse", "Communication time", "Hello", etc.) are
It is written in advance into the ROM 3 shown in FIG. 1st
The buffer memory 2 shown in the figure can be written to from any of the data buses of the CPU included in the band compression unit 4, ROM 3, and system control unit 7, and is included in the band compression unit 4, transmission control unit 5, and system control unit 7. It is possible to continue outputting to any of the CPUs. That is, as shown in FIG. 2, four bidirectional bus drivers 27 to 30 are connected to the data input/output of the buffer memory, and these chip enables enable reading and writing to each section.

The buffer memory 2 has a reserve area A for management information and an area B for image information as shown in FIG. It is set. Further, link designation (hereinafter abbreviated as link designation) as to which block is to be read or written to the buffer memory is initially set to the write state from the band compression unit 4. That is, in FIG. 2, the bidirectional bus driver 27 is chip enabled.

When the manuscript is manually edited in this state, the image information scanned by the continuous output section 1 is encoded by the band compression section 4 and written in the area B in FIG. 3(A). Upon completion of scanning, the link designation is set to write from the ROM 3, thereby making the bidirectional bus driver 28 in FIG. 2 chip-enabled, and at the same time clearing the address counter 31. Thus R.O.
The fixed pattern of management information written in advance in M3 is transferred to reserve area A of the buffer memory. At this point, the contents of the reserved area A of the buffer memory are shown in Figure 3 (
The situation is as shown in b). Next, specify the link as CPU
Set to write from the data bus and write management information to the CPU.
Write to a fixed address in the buffer. At this point, the uncompressed management information is stored in the reserved area A of the buffer memory as shown in Figure 3, and the management information is stored in the reserved area A of the buffer memory, and
The image information of the input original is stored in compressed form.

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

The linear density converter 8 has this function. This configuration is shown in FIG. In principle, when the linear density becomes m times finer in the scanning direction, the read clock from buffer memory 2 is transferred and divided by 17 m of the lock, and when it becomes n times finer in the sub-scanning direction, it is written at the same time as reading. It is desired to read data from the line memory 13 corresponding to one line (n-1) times, but not to read data from the buffer memory 2 containing management information during that time.

Next, set the link designation to read to the band compression unit 4 and the transmission control unit 5 (chip enable the bidirectional bus driver 30 in FIG. 2), and at the same time input data from the transmission control unit 5 to the band compression unit 4 side. setting, and the data input of the band compression section 4 is switched from the reading section 1 to the buffer memory 2. As a result, the management information is encoded by the band compression section 4 and transmitted from the transmission control section 5 through the line control section 6. At this time, the management information end detection unit 33 shown in FIG. , and the data input of the band compression section 4 is returned to the reading section I side.

In this way, the transfer is restarted, and the compressed information of the input document is transferred from area B of the buffer memory to the transfer control section 5.

In this way, a recording surface with sender management information recorded in the received image header is obtained.

In this embodiment, fixed management information is written in the ROM 3, but it may be written directly in the buffer memory 2.

As described above, the present invention can record management information from the sending side, such as the transmitter number, the user who used the transmitter, and the message from the sending side, on the received image together with the received original image. Furthermore, it is possible to obtain an excellent facsimile machine that can record variable management information such as transmission date and time on a received original image.
