DETAILED DESCRIPTION OF THE INVENTION [Field of the Invention] The present invention relates to a data communication device for transmitting and receiving data such as image data and character code data.

[Prior art]

Conventionally, in this type of device, such as a facsimile machine, when a document is sent, the sender cannot confirm whether or not the receiver has viewed the document.

Therefore, in order to confirm, it is necessary to use a telephone or the receiving side must dial again and send a reply document to the sending side, which has the disadvantage of being time-consuming and time-consuming. Ta.

〔the purpose〕

The present invention eliminates the drawbacks of the prior art described above, and provides a data communication device that allows the sending side to receive reply data to the transmitted data, and allows the receiving side to easily send reply data to the received data to the sending side. This is what we provide.

〔Example〕

Hereinafter, one embodiment of the present invention will be described in detail using a facsimile machine.

FIG. 1 is a block diagram of a facsimile machine showing an embodiment of the present invention, and FIG. 2 is a diagram of an operation panel of the facsimile machine.

The RAM 3 stores the binary image data read by the reading section 6 or the binary image data recorded in the recording section 6.

Further, the RAM 3 stores the telephone number and confirmation message of the other party's device when data is received.

Character generator (CG) 4 is JIS code,
This is a ROM that stores characters such as ASCII codes, and extracts character data corresponding to a predetermined code using 2-byte data as necessary under the control of the CPU.

The recording unit 5 is a DMA controller and a sub CPU.

Consists of thermal head, TTL, IC, etc.
The recording data stored in the RAM 3 is taken out under the control of PtJl and printed out as a hard copy.

The reading unit 6 is a DMA controller and a sub CPU.

It is composed of a CCD, TTL, IC, etc., and under the control of cpUl, data read using the CCD is binarized, and the binarized data is sequentially sent to the RAM 3.

The modem section 7 has G3. G2. FM modem, and a clock generation circuit connected to these modems, modulates the transmission data stored in the RAM 3 under the control of the CPU t, and sends it to the telephone line 9 via the NCU 3. This is what is output. Furthermore, the modem section 7 introduces an analog signal from the telephone line 9 via the NCU 9, demodulates it, and stores the binarized data in the RAM 3.

The NCU 3 switches and connects the telephone line to either the modem section 7 or the telephone set 10 under the control of the CPUI.

The operation unit 11 includes a key 21 for starting transmission, reception, etc.
, a mode selection key 22 for specifying an operation mode such as fine, standard, or manual reception during transmission and reception, a confirmation button 23 used when transmitting a confirmation message, and a numeric keypad 24. In addition, C
The PUI detects the pressed state of these keys and controls the above-mentioned parts according to the pressed state.

The display unit 11 is a liquid crystal display, and displays predetermined characters and the like under the control of the CPU 1.

FIG. 3 is a control flowchart of the CPU 1 when receiving a document, and FIG. 4 is a control flowchart of the CPU 1 when transmitting confirmation information.The present embodiment will be described below based on these flowcharts.

First, when there is a call from the telephone line 9, the NCU 3 switches the line from the telephone 10 to the modem unit 7 in the case of automatic reception. Then, in step S2, a communication mode is set by exchanging procedure signals with the transmitting device. Also, at this time, the telephone number of the other party's device is recognized in step S4, and the telephone number is stored in the RAM 3 together with the number and the date and time of reception in step S6.

Next, in step S8, image data is received and stored in the RAM3. When the reception of the image data is completed, in step S10, procedure signals are exchanged until the line is disconnected, and in step S12, the image data stored in the RAM 3 is printed out by the recording unit 5.

In step 314, a message requesting confirmation that the document previously stored in the ROM 3 has been viewed is converted into text by the CG 4 and displayed after the document output in step S12. At this time, the number stored in step S6 is also attached to the message. Fifth
The figure shows an example of the message at this time.

FIG. 4 shows the operation of the CPU 1 when the confirmation button 23 is pressed, and when the confirmation button 23 is pressed, step S22
” is displayed on the display unit 11. If the number has been entered manually, the process advances to step S26, and R
The telephone number corresponding to the number pressed in step S24 is read from AM3, and the telephone number is dialed in step 328.

In step S30, procedure signals are sent and received and a communication mode is set. Next, in step S32, it is determined whether or not an original is set. If the original is not set, the reception date and time corresponding to the above-mentioned numbers are read from the RAM 3, and a confirmation message stored in the RAM 3 in advance is sent to the CG 4. Convert the code data to character data and send it. Further, when a document is set in step S32, the data is read by the reading section 6, modulated by the modem section 7, and sent out. Finally, in step S38, procedure signals are sent and received until the line is disconnected, and the process returns to the standby state.

On the receiving side of the confirmation message, since the date and time of receipt are sent together with the confirmation message, the person receiving the confirmation message can immediately understand which manuscript the confirmation message is for.

Furthermore, if the date and time when the confirmation button 23 was pressed on the receiving side is attached to the confirmation message, the sending side can also know the date and time when the confirmation was confirmed by the receiving side.

Furthermore, in the above embodiment, a case was explained in which confirmation information or a reply manuscript can be sent for all received data, but by issuing a command only when confirmation is necessary from the sending side, confirmation information can be sent only at that time. You can also send it. In this case, the sending side may send a signal to the receiving side as to whether or not confirmation information is necessary when transmitting and receiving the procedure signal in step S2.

FIG. 6 shows a flowchart of the operation control of the CPU on the receiving side at this time. Incidentally, in FIG. 6, the steps having the same step numbers as those in FIG. 3 perform the same operations as described in FIG. 3. Also, in step S3, step S2
It is determined whether or not a signal indicating that confirmation information is required has been sent from the partner device. If necessary, the process proceeds to step 53-1, and the confirmation flag is turned on; if not, the process proceeds to step S8.

In step Sll, it is determined whether or not the confirmation flag is on, and if it is on, step Sll is executed after outputting the document.
At step 14, a message requesting confirmation is displayed, and if the confirmation flag is not turned on, the document is output and the process returns to the standby state.

In the above-mentioned embodiment, a facsimile machine was used to output data stored in a memory, but the present invention is also applicable to a facsimile machine that prints out data at the same time it is received, or a facsimile machine that outputs data that is stored in a memory without printing it out. The present invention can be similarly used in a facsimile machine that files stored data on an external storage device such as a floppy disk.

Furthermore, the present invention is not limited to facsimile machines,
It can be used in a data communication device such as Teletex that transmits and receives character code data.

〔Effect of the invention〕

As explained above, by using the present invention, the data transmitting side can return the transmitted data.
