Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a communication confirmation system in a facsimile device, particularly in a facsimile device on the receiving side.

[Prior art]

Some conventional receiving facsimile devices return a signal indicating completion of reception (a confirmation signal indicating normal reception, number of pages received, etc.) after the sending facsimile device completes transmission. There is. However, in this case, it is not possible to check on the sending facsimile device whether there is a page omission or the degree of disturbance in the image signal.

On the other hand, it is also possible to provide a printer section in the sending facsimile device and monitor copy (record on the own printer while transmitting to the other party's) a part or all of the transmitted image signal in the printer section. In such cases, it is not possible to confirm whether the transmitted image signal has properly arrived at the receiving side or whether the print quality has changed due to disturbances in the received signal.

Further, Japanese Patent Application Laid-Open No. 132937/1983 describes a received image return mechanism configured to newly read an image signal recorded on the receiving side and send it back to the transmitting side. However, this mechanism requires a separate means for reading what is recorded, making the configuration complicated. Furthermore, this mechanism can only be applied to real-time reception (recording what is received immediately) and cannot be applied to memory reception at all.

Furthermore, Japanese Patent Laid-Open No. 54-81714 discloses that the receiving side detects the density of a specific part of the image information recorded, sends it to the sending side, and compares it with the density value separately printed and measured on the sending side. The configuration is described. However, this mechanism also newly reads the recorded image information in the same way as in the above example, and a separate means for that purpose is required.

[Purpose of the invention]

The present invention has been made in view of the above points, and
It is an object of the present invention to provide a facsimile device capable of checking the presence or absence of missing pages, the state of image disturbance, etc. on the sending side.

[Structure of the invention]

In order to achieve the above object, the facsimile apparatus of the present invention includes, on the receiving side, a counter that counts the image signals transmitted from the transmitting side, and a cutout setting section that sets a predetermined position of the image signal to be cut out.
a storage memory that stores the extracted image signal; a cropping control section that stores a predetermined image signal in the storage memory in response to setting position information from the cropping setting section and output of the counter; and a transmission from a transmitting side. A line control section is provided which sends the stored image signal back to the transmitting side after completion.

〔Effect of the invention〕

According to the present invention, a part of the transmitted image information is stored in the receiving side memory, and after the transmission is completed, the extracted image signal stored in the memory is returned to the transmitting side, so that the information that has reached the transmitting side is You can check the content, recognize the characters in titles, etc., check whether pages are missing, and whether the images are distorted. Moreover, the memory capacity on the receiving side for this purpose is small, and the return time can be extremely shortened.

Further, according to the present invention, since a configuration is adopted in which the cut out image signal stored in the storage memory is sent back, the reception is not limited to real-time reception, and for example, confidential reception or during copying. This can also be realized when receiving data, such as receiving data.

〔Example〕

FIG. 1 is a block diagram showing the configuration of an automatic sending/receiving facsimile apparatus of the present invention. In FIG. 1, 1 is a line control unit that detects an incoming call from the sending side and connects a transmission line or issues a transmission request; 2
is a demodulation unit that demodulates the transmitted signal and extracts image information;
3 is a decoding unit that expands and decodes the compressed image information into an image signal; 4 is a recording unit that prints the image signal on recording paper; and 5 is only a preset image signal among the above image signals. 6 is an encoding unit that compresses and encodes the stored image signal; 7 is an encoding unit that compresses and encodes the stored image signal;
is a modulation unit that modulates the encoded image signal so that it can be transmitted. Further, 8 is a communication control section 9 that controls the line control section 1, demodulation section 2, and modulation section 7, and is a storage control section that controls the storage section 5, decoding section 3, etc.

FIG. 2 shows details of the storage section 5 and storage control section 9. As can be seen from the figure, the storage control unit 9 includes a counter for counting image signals, that is, a pixel number counter 10 and a scanning line number counter 1.
1. A cutout setting section 12 that sets a predetermined image signal position to be cut out, and a storage memory 13 in the storage section 5 according to the setting position information from the cutout setting section 12 and the outputs of the counters 10 and 11;
A cutout control section 14 is provided that causes the storage memory 13 to record the image signal at the set position.

Next, the operation of the storage control section 9 will be explained. The signal received by the line control section 1 is demodulated by the demodulation section 2, and then becomes an image signal at the decoding section. This image signal is a scan start signal indicating the start of a scan line and pixel data for each scan line. The scanning start signal counts up the scanning line number counter 11 and resets the pixel number counter 10. The pixel number counter 10 counts up each time pixel data is sent to the recording section. On the other hand, in the cutout setting section 12, cutout position data indicating predetermined positions of the transmission document, such as the positions A, B, and C in FIG. 3, is input. Cutout control section 14
Now, this cutout position data and counter 10,
11, the storage memory 13 is controlled and the image information of the cut out portion is stored in the storage memory 13. Further, the cutout control unit 14 edits the cutout portion of each page of the transmission document and controls the writing position in the storage memory 13 so as to configure a screen to be sent back to the sending side.

Thereafter, when the line control unit 1 detects the end of transmission from the sending side, it immediately issues a return request to the sending side.
If the return request is accepted, the storage memory 1
3 is transmitted to the transmitting side by the line controller 1 via the encoder 6 and the modulator 7. On the sending side, the information returned in this way is printed in the recording section. An example is shown in FIG. In the figure, a text or telephone number is printed in the heading E to clearly indicate that the return signal is from the receiving side. The actual confirmation information is in the format shown in return information section d, which allows the sending side to know whether there are any missing pages, the state of the image quality, etc.

Note that pages, symbols, etc. are written in advance at positions A, B, and C of the transmission document shown in FIG. The positions of A, B, and C may be fixed to any one, or the user may be able to select and set them as necessary. If the selection method is used, the sender instructs the setting position information using an operation button, etc., and according to the instructions, the sender sends it as a device control signal to the receiving side before sending out the image signal, and the sending side receives the setting position information. It is necessary to input it to the cutout setting section 12.

Further, in this embodiment, part or all of the image signal is sent back at the same level, but it goes without saying that the reduction can be set freely.
