Description

DETAILED DESCRIPTION OF THE INVENTION [Summary] This is a device for notifying the transmission of blank images in a facsimile device, and transmits the number of blank pages to the sending side at the end of reception. Further, when it is determined that the paper is blank, no recording operation is performed.

[Industrial application field]

The present invention relates to a blank image reception notification device in a facsimile device, which has a function of notifying a sending side of a blank image and reception when a blank page is received.
More specifically, the present invention relates to a blank image reception notification device that transmits the number of blank sheets to the transmitting side at the end of reception and does not record blank sheets.

Regarding facsimile devices, there are those that transmit with the written side, such as characters, on the front side, and those that transmit with the side with characters written on the back side. On the other hand, when a large number of originals are sent at once, even if the originals include the front and back pages, the originals may be sent without being noticed.

Therefore, it is desired to provide a device that can send a warning message to the sending side upon receiving a blank page.

[Conventional technology]

A typical G3 or G4 type facsimile device is composed of an NCU 1, a modem 2, a control board 3, etc., as shown in Fig. 3, and the control board 3 includes a bus 1
0, a CPU 4, a CG expansion circuit 5 for expanding character codes into bit signals, an encoding/decoding circuit 6, a destination number storage memory 7, an image data save memory 8, a recording circuit 9, etc. are connected.

Facsimile devices with such a circuit configuration generally do not have a function to determine whether the transmitted original image is a blank image or not, and therefore, transmission is performed regardless of whether the original is front or back, and may not be sent normally. Since the process ends, the operator may not notice even if a blank image is sent. On the other hand, devices have been developed that determine the proportion of white parts in the transmitted original image and notify the operator that a blank original image has been sent.
At present, when such devices are not widely used, it is difficult to prevent inconveniences caused by sending and receiving blank original images.

[Problem that the invention seeks to solve]

In this conventional device, only the sending side can check whether a blank original image has been sent. Furthermore, after finding a blank image included in the received original image, the receiving side needs to contact the sending side to request retransmission.

The present invention has been made in view of these points, and provides for efficiently processing blank image transmission by automatically sending a warning message to the sending side when the received image is a blank image. It is an object.

[Means for solving problems]

FIG. 1 shows a principle block diagram of a blank image reception notification device of the present invention.

In the figure, the present invention is a device that notifies a sending side that a blank image has been sent, and detects whether or not a received image line is a NOT white line.
It includes a NOT white line detection means 13, a memory 8A for storing image lines in page units, and a NOT white line counter for counting up each of the NOT white line signals from the white line detection means 13. a control means 14 that generates a recording instruction signal when the count value of the NOT white line counter is zero, generates a non-recording instruction signal when it is not zero, and generates a count-up signal when the count value is less than a predetermined value; In response to a recording instruction signal from the recording circuit 9 and the control means 14, the recording circuit 9 causes the recording circuit 9 to record a page corresponding to the recording instruction signal in the memory 8A, and in response to an unrecorded instruction signal, causes the recording circuit 9 to record a page corresponding to the recording instruction signal from the memory 8A. recording control means 15 for stopping the recording by the recording circuit 9 of the page corresponding to the unrecorded instruction signal; and the control means 14
a blank sheet number counter 12 that is counted up in response to a count up signal from the blank sheet number counter 12, and a blank sheet notification image creation section 16 that transmits a message corresponding to the count value of the blank sheet number counter 12 at the end of image reception to the sending side. provided and configured.

[Effect]

The NOT white line among the received image lines is
It is detected by the white line detection means 13. was detected
The NOT white line signal is supplied to the control means 14 to count up the NOT white line counter. Each image line is also stored in memory 8.

When the received image line becomes the page end image line, if the count value of the NOT white line counter is not zero, the control means 14
generates a recording instruction signal. The recording control means 15 in response to this recording instruction signal causes the recording circuit 9 to perform a recording operation of the page stored in the memory 8, but if the count value of the NOT white line counter is zero, the control means 14 generates a non-recording instruction signal, so that the recording circuit 9 does not perform a recording operation.

Therefore, waste of recording paper can be avoided.

In addition to this failure to generate a record, the control means 14 generates a count-up signal to increment the blank sheet number counter 12, and the counter value at the end of image reception is determined by the blank sheet notification image creation. This is used to notify the transmitting side of the number of blank pages produced by the unit 16. This notification is displayed when, for example, all pages are blank.
It can be used to help retransmit the data.

〔Example〕

FIG. 2 shows one embodiment of the invention. In Figure 2, 1 is an NCU, 2 is a modem, 3 is a control board,
4 is a CPU, 5 is a CG expansion circuit for expanding a character code into a bit signal, 6 is an encoding/decoding circuit, 7 is a destination number storage memory, and 8 is an image data save memory (as described in the claims). ), 9 is a recording circuit, which is the same as that shown in FIG. FIG. 2 further shows a character table (warning table) 11 for warning messages, a blank sheet number counter 1
2, and a NOT white line counter 13 as NOT white line counting means. It is also possible to use a white line counter instead of the NOT white line counter 13. A program for executing the processing flow shown in FIG. 4 is stored in the destination number storage memory 7.

FIG. 4 shows the processing flow of the embodiment of the present invention, in which reception is started in step S22, reception of the other party's number is determined in step S21, and the other party's number is saved in step S22. In step S23, the blank sheet number counter 12 is cleared, and in step S24, the NOT white line counter 13 is cleared. Furthermore, the steps
In step S25, one line of image data is saved, and in step S26, a page end is checked. If a NOT white line is detected in step S36 before reaching the page end, the step
At S37, the NOT white line counter 13 is incremented. The process in step S36 and the CPU 4 that performs this process correspond to the NOT white line detection means 13 in FIG. Note that when detecting the NOT white line, the level is selected appropriately so that noise on the screen included in the white line can be distinguished from characters or figures. Page end is a step
If detected in S26, it is determined in step S27 whether or not the NOT white line counter 13 has been incremented. As a result, if it has not been incremented, the blank sheet number counter 12 is incremented in step S28. Step S26,
Perform the processing in S27, S37, and this processing
The CPU 4 corresponds to the control means 14 in FIG.
In step S29, it is determined whether there are any more images to be transmitted, and if there are any more images to be transmitted, control returns to step S24. If it is determined in step S29 that there is no transmitted image, the contents of the blank sheet number counter 12 are referred to in step S30, and if the value of this counter is 0, the receiving operation is terminated in step S38. On the other hand, if the number of blank sheets is recorded in the blank sheet number counter 12, the model is checked in step S31, and if it is a G4 model, the transmission right is obtained.
For other models, the other party's number in the memory is referenced in step S34 and the process proceeds to step S35.
A call is made, and the warning message read from the blank paper warning character table 11 and the number of blank sheets saved in the blank sheet number counter are transmitted. The processing in steps S31 to S35, and the CPU 4, control board 3, modem 2, and
The NCU 1 corresponds to the blank notification image creation unit 16 in FIG. Furthermore, for models that cannot confirm the other party's number, there is no way to notify the sender of a blank page warning, so the process ends as is. Note that when a page memory is used instead of a line memory, the blank sheet number counter 12 may be incremented by determining the ratio of white or black areas in the page memory when each page end is detected. Further, when using a page memory, unnecessary consumption of recording paper can be prevented by not performing a recording operation when it is determined that the paper is blank. The process in step S27 described above and the CPU 4 that performs this process correspond to the recording control means 15 in FIG.

〔Effect of the invention〕

As described above, according to the present invention, by transmitting the number of blank pages to the transmitting side at the end of reception, it is possible to resend the original. This helps in successful submission of the manuscript. In the blank page determination, no recording is performed, so it is possible to avoid wasting recording paper.
