Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention provides a facsimile machine that determines the proportion of white image information in transmitted image information and performs communication control based on this determination result. It is related to.

[Prior Art] A conventional facsimile machine automatically answers an incoming call from a sender's facsimile machine, receives image information sent from the sender's facsimile machine, and faithfully records the image information as it is. It becomes.

``Problem to be Solved by the Invention J'' The conventional facsimile machine described above receives image information sent from the sending facsimile machine and faithfully records it as is. Even when a transmission original is set with the front and back sides reversed and sent, the transmission image of this original, that is, the white image data, is received and recorded as is, which causes a problem in that recording paper is wasted. .

"Means for Solving the Problems" In order to solve these problems, the facsimile apparatus according to the present invention includes a determination means for determining the proportion of white image data in received image data, and a determination means for determining the proportion of white image data in received image data. A station line opening control means for opening the station line when the proportion of white image data is determined by the means to be equal to or higher than a predetermined ratio.

The apparatus also includes transmission control means for transmitting an alarm signal to the other party's facsimile machine when the determination means determines that the ratio of white image data is equal to or higher than a predetermined ratio.

[Operation] If the proportion of white image data in the received image data is equal to or higher than a predetermined proportion, the station line is opened.

Further, when it is determined that the ratio of this white image data is equal to or higher than a predetermined ratio, an alarm signal is transmitted to the other party's facsimile machine.

[Example] Next, the present invention will be explained with reference to the drawings.

FIG. 1 is a block diagram showing a second embodiment of a facsimile apparatus according to the present invention. In the same figure, 1 is a CPU,
2 is a modem, 3 is an image sensor for reading a document, 4 is a head for recording received image data, 6 is a display section for various displays, and 7 is for dialing the other party's facsimile device. A dial key, 8 is a communication key for starting facsimile communication, and SP is a speaker.

After automatically responding to the call signal from the central office line, the CPU 1 receives the image data from the other party's facsimile machine, drives the head 4 to record it on the recording paper, and also occupies the image data. If the ratio of white image data is determined and the ratio of white image data exceeds a predetermined ratio, immediately release the central line or send a message to the other party's facsimile machine indicating that the ratio of white image data is high. - A control signal (alarm signal) indicating that the scanned original data is being transmitted is sent and displayed.

Next, FIG. 2 is a block diagram showing a second embodiment of this facsimile machine. The facsimile machine shown in FIG. 2 is the facsimile machine shown in FIG. 1 with a page memory 5 added thereto. Then, while receiving image data from the other party's facsimile device, image data corresponding to one page of the transmitted document is stored in the page memory 5, and the ratio of white image data to the stored image data is determined. If the ratio of white image data exceeds a predetermined ratio, either the central office line is immediately disconnected as described above, or a control signal is sent to the other party's facsimile machine to indicate that original data set upside down is being transmitted. Since this method is designed to transmit and display the information, there is an advantage over the first embodiment shown in FIG. 1 in that not a single sheet of recording paper is wasted.

The operation of each embodiment of the present invention will be described below.

FIG. 3 is a flowchart illustrating the processing contents of the CPU 1 that performs the operation of the first embodiment.

First, in step 50, it is determined whether an incoming call has arrived from the other party's facsimile machine via the central office line, and if the incoming call has arrived,
'', in order to automatically answer this incoming call, a central office line acquisition process is performed in step 51, and then in step 5.
In step 2, it is determined whether the other party is a fax machine, that is, whether the other party's device is a facsimile machine. If the other party's device is not a facsimile device, other incoming call response processing is performed in step 53, and the process ends.

Further, if the other party's device is a facsimile device, the determination in step 52 is "Y", and in this case, the next step is step 54.
to receive the image data of the original sent from the other party's facsimile machine. Then, in step 55, the number of lines of this received image data is counted, and in step 56, the number of lines of self-portrait data in this received image data is counted, and in step 57, this received image data is recorded. thus,
After this received image data is recorded, step 58
It is determined whether recording of the first page of the received original has been completed or not, and if recording of the first page of the original has not been completed, the process returns to step 54 and image data of the first page of the original is subsequently received. However, when the first page of the original is recorded, it is determined in step 59 that the number of white lines/number of read lines ≧ 0.9, that is, the number of lines of the counted self-portrait data is 90% of the number of read lines of the received image data. A judgment is made as to whether or not it occupies the above amount.

If the number of lines of the self-portrait data is less than 90%, it means that the image data of the document set normally has been received, and it is judged as "N" in step 59, and then the next page's document data is In order to prepare for reception, the received image data line counter and the white image data line counter are cleared in step 60, and it is determined in step 61 whether recording of all pages has been completed. If the recording of all pages is completed and the determination is "Y", the process ends immediately; however, if the recording of all pages is not completed, the process returns to step 54 to receive the image data of the next page of the document.

Further, if it is determined that the number of white lines accounts for 90% or more of the number of read lines, "Y" is returned in step 59,
In this case, the original sent from the other party's facsimile machine was sent face down.
In step 62, the received image data line counter and white image data line counter are cleared, and in step 63, an alarm is output from the speaker SP to the facsimile machine on the receiving side, and the captured station line is cleared in step 64.
The timer is opened at step 65, and the timer is started at step 65, and the time-up of this timer is determined at step 66.

Then, in step 66, the timer times out and
If it is determined "Y", in step 67 a dial search is performed, that is, the dial number of the other party's facsimile machine is searched from the transmission data sent from the other party's facsimile machine, and in step 68 the central office line is automatically captured and this search is performed. Automatic dialing processing is performed to send the dialed number data to the station 11L. In this way, when a response from the other party's facsimile machine is detected in step 69 by dialing the other party's facsimile machine, a control signal indicating that the document is set face down is sent to the other party's facsimile machine in step 70. to display on the other device,
Thereafter, in step 71, the central office line is released and the process ends.

Next, FIG. 4 is a flowchart explaining the operation of the second embodiment shown in FIG. In Figure 4, the third
Portions equivalent to those in the flowchart in the figure are given the same reference numerals, and their explanation will be omitted.

Automatically answers an incoming call from the other party's facsimile machine, receives image data and stores it in the page memory 5,
Once the number of lines of this image data and the number of lines of self-drawing data in this image data have been counted, it is determined in step 80 whether or not all of the first page of the manuscript has been stored in the page memory 5. However, if the first page is not completely memorized, the process returns to step 54 to continue receiving the image data of the first page. However, once the first page of the manuscript is recorded, the process proceeds to step 81 as described above. It is determined that the number of white lines/number of read lines≧09.

If the number of lines in the self-portrait data is less than 90%, it means that the image data of the original set normally has been received, and it is determined in step 81 that the number of lines is 1N. The stored image data is recorded on recording paper in step 82, and then in step 83 the received image data line counter and white image data line counter are cleared in preparation for receiving the next page of original data. In step 84, it is determined whether all pages have been recorded. If the recording of all pages is completed and the determination is "Y", the process ends immediately; however, if the recording of all pages is not completed, the process returns to step 54 to receive the image data of the next page of the document.

Furthermore, if it is determined that the number of white lines accounts for 90% or more of the number of read lines, it is determined as "Y" in step 81, and in this case, the original to be sent from the recipient's facsimile machine is placed face down. Since it has been transmitted, the received image data line counter and white image data line counter are cleared in step 85, and in step 86, an alarm is output from the speaker SP to the facsimile machine on the receiving side, and the document is set face down. Step 8
At step 7, the information is transmitted to the other party's facsimile machine and displayed on the display unit 6 of the other party's apparatus, and also recorded on the recording paper of the other party's apparatus. Thereafter, at step 88, the central line is released and the process ends.

Note that in this embodiment, if the other party's facsimile device sends the document data in a reversed state,
Before the central office line is released, a control signal is sent to the other party's facsimile machine so that the display section 6 and the recording paper display "Paper document set 1 - miss". At this time, the speaker SP of the other party's facsimile machine It may be configured to send out a discharge signal to call an operator.

In addition, if this facsimile machine is a G4 facsimile machine used on a digital line, the calling number of the other party's facsimile machine is received, and when the other party's facsimile machine enters the state of "original setting error", the calling number is The configuration may be such that dialing is made to the other party's facsimile machine based on the .

[Effects of the Invention] As is clear from the above explanation, the facsimile device according to the present invention opens the central office line when the proportion of white image data in the received image data is equal to or higher than a predetermined proportion. In addition, if the ratio of white image data exceeds a predetermined ratio, an alarm signal is sent to the other party's facsimile machine, so it is possible to set the original to be sent upside down on the sending facsimile machine. When the information is transmitted, the central office line can be opened or an alarm signal can be sent to the sending facsimile machine to warn the user, which has the effect that recording paper can be used more effectively.
