Abstract

PURPOSE:To confirm an image obtained on a reception side by providing an image reception means and a reception image returning means to return a received image to a transmission side in facsimile equipment on the reception side, and discriminating the image sent from the transmission side. CONSTITUTION:The transmission side transmits the transmission image of an original from a facsimile basic part 22, and a facsimile basic part 26 on the reception side receives and records it. At the facsimile equipment 24 on the reception side, a form on which recording is performed is read by a reception image re-transmission part 28, and image data obtained as a result is sent to a reception state confirming part 23 on an outgoing side via a reception side line 27. Therefore, it is possible to recognize what the image recorded on a recording form is at the facsimile equipment 21 on the outgoing side. Therefore, since the state of the image received on the reception side can be confirmed, the overlapped transmission of the original on the transmission side can be detected even when it occurs.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a facsimile device that transmits and receives images, and particularly relates to a facsimile device that can confirm the reception status of images.

[Conventional technology]

Facsimile machines are rapidly becoming popular due to their speed, which allows documents to be sent to various locations over lines.

However, since facsimile machines normally use a line, it is not possible to send good images if the line condition deteriorates. Therefore, a situation may occur in which important documents are sent in an unrecognizable state. In order to prevent such a situation, conventional practice has been to switch the line from facsimile communication to a telephone immediately after sending, or to make a new call to the receiving party to check the reception status.

[Problem to be solved by the invention]

However, especially when the transmission is performed at night, there is often no one at the receiving end, making such confirmation difficult. Furthermore, even if there is a person at the receiving end, it is difficult to determine from conversation alone whether the receiving end received the message in the manner intended by the receiving end.

SUMMARY OF THE INVENTION Therefore, it is an object of the present invention to provide a facsimile machine that can confirm the image reception status on the receiving side without human intervention.

[Means to solve the problem]

In the present invention, (i) an image receiving means for receiving an image sent from the sending side, and (ii) a received image returning means for returning the received image to the above-mentioned sending side, are connected to a facsimile device on the receiving side. be equipped.

Thereby, the facsimile machine on the sending side can confirm the image obtained on the receiving side by identifying the image sent from the receiving side. Here, the image returned by the receiving side may be the state of the electrical signal stored in the receiving side's memory at the time of reception, or the image recorded on the recording paper and read by the receiving side. There may be. In the latter case, it becomes possible for the sending side to confirm whether or not there is a problem with the recording device.

〔Example〕

The present invention will be described in detail with reference to Examples below.

FIG. 1 shows an outline of the configuration of a receiving side device as a facsimile device of this embodiment.

This facsimile machine has a CPU (Central Processing Unit) 11
It is connected to the following parts via a bus 12 such as a data bus.

(i) ROM 13: This is a read-only memory that stores programs for controlling various types of this facsimile machine.

(ii>RAM 14: Random access memory used for temporary storage of data for various controls and received image data.

(iii>Communication control unit 15: Used to send data to the other party's facsimile machine via the telephone line and to receive data sent from the other party.

(iv) Reading unit 17: This is a unit that reads images from a document, and is usually equipped with a one-dimensional image sensor.

(v) Recording unit 18: This is a unit that records received images. There are various recording methods such as a thermal transfer method, a dot impact method, and an electrostatic recording method.

(vi) Operation panel 19: This is a panel for performing various operations. The facsimile machine of this embodiment also has a function of transmitting images, and is provided with a key switch for setting a return mode for requesting the other party's facsimile machine to return the received image. In addition, the return mode is one of two modes: a received signal confirmation request mode that requests the return of the received image data itself, and a received image confirmation request mode that reads the image recorded in the other party's recording unit and sends it back. You can now choose.

FIG. 2 shows a facsimile communication system using this facsimile device.

The facsimile device 21 on the sending side includes a basic facsimile unit 22 that has at least a document reading function and an image data transmitting function, and a reception status confirmation unit 23 that checks the image sent from the receiving side. ing. On the contrary,
The facsimile device 24 on the receiving side includes a basic facsimile unit 26 that has at least the function of receiving image data sent through the transmission line 25 and the recording function of reproducing an image based on the received image data. The facsimile apparatus includes a received image retransmission section 28 that reads the recorded image and sends it to the reception status confirmation section 23 of the facsimile machine on the sending side via the receiving side line 27. Then, on the sending side, the facsimile basic section 22 transmits the transmitted image of the document, and the facsimile basic section 26 on the receiving side receives and records it. The process up to this point is similar to a conventional facsimile system.

In the facsimile device 24 on the receiving side, the received image retransmission unit 28 reads the recorded paper and sends the resulting image data to the receiving status confirmation unit 23 on the sending side via the receiving line 27.

Therefore, the sending facsimile device 21 can know what kind of image is recorded on the recording paper. Of course, since the receiving facsimile machine of this embodiment can write one page of image data into the RAM 14, it is also possible to return the image data as is to the sending facsimile machine 21. Trouble caused by the line or the sending facsimile device can be easily determined by this.

FIG. 3 shows the details of the control taken by the facsimile machine on the receiving side to realize such facsimile communication.

In the facsimile machine on the receiving side shown in FIG. 1, when a facsimile signal is sent from the sending side (step ①;
Y) The control signal determines whether the transmitting side is (a) requesting confirmation of the received signal, (b) requesting confirmation of the received image, or (c) not making any of these requests. (Steps ■, ■).

If the transmitting side requests confirmation of the received signal (step ■; Y), the image is recorded in the recording unit 18 at the same time as the image is received (step ■), and when this is completed, the RA
The image data is read from M14 and the reception signal (received image data) is returned from the communication control unit 15 (step ■).As a result, the reception status recognition unit 23 shown in FIG. You can record and check the number of returned images.

On the other hand, if the sending side requests confirmation of the received image, the image is recorded in the recording section 18 (step ■; Y), and when this is completed, it is recorded on the recording paper. The captured image is read by the reading section 17 (step 2). The read image is transmitted from the communication control unit 15 (step (2)). Please note that some facsimile machines on the receiving side may not have large memory capacity.
Sometimes images cannot be saved. In this case, 2. Even if there is a previous received signal confirmation request, the image can be confirmed by performing the control in steps ① to ②.

Finally, if there is no request for confirmation from the transmitting side (step 2; N), normal recording is performed in the recording unit 18 (step 2), thereby terminating the communication.

〔Effect of the invention〕

As described above, according to the present invention, it is possible to check the state of the received image on the receiving side, so even if double feeding of documents is performed on the transmitting side, this can be detected. Furthermore, it is possible to check the image reception status with the same line occupancy rate as in conventional facsimile communication, and the reliability of the facsimile communication system can be improved.
