Description

How to prevent white paper from fax machines {METHOD FOR CHECKING WHITE LINE FOR TRANSMITTING IN FAX SYSTEM}

The present invention relates to a method for transmitting an original from a facsimile, and more particularly, to a method for preventing a blank paper from being inserted due to an incorrect insertion of an original to be transmitted.

The facsimile apparatus plays an important role as a medium of information communication which is indispensable in the modern times which requires rapid information sharing. The facsimile apparatus has a unique function of printing an original by sending or receiving an original.

The procedure for transmitting an original among the unique functions of the facsimile apparatus is described. When the user inserts a document to be sent and inputs a telephone number for calling the receiving side facsimile apparatus, the facsimile apparatus dials the telephone number input by the user. Calls the receiving fax machine. In response to the call, when the receiving side facsimile apparatus responds, the protocol for transmitting the original is performed. If the protocol is successfully executed, the facsimile apparatus scans the inserted original by the user's request for transmission, converts it into image data, and transmits the converted image data to the receiving side facsimile apparatus.

In the above-described process, when inserting an original to be transmitted for the first time, a user often inserts the back side of the original in which the content to be transmitted is written in confusion with the scanning surface of the CIS provided in the scanner. Therefore, when the back side of the transmission original is inserted, the transmission original should not be transmitted. Therefore, it is necessary to detect the back insertion state, stop the transmission, and notify the user.

Conventionally, when an original to be transmitted is incorrectly inserted as described above, a character is scanned by the white paper or the back side of the text, and the receiving side facsimile apparatus receives a white paper or an unnecessary document.

Accordingly, an object of the present invention to solve the above problems is to provide a method for automatically stopping the transmission of a document when a number of blank lines defined by the user in the facsimile apparatus is detected.

Another object of the present invention is to provide a method for outputting a guide document describing a method of generating an error sound and inserting an original to be transmitted when a number of blank lines is detected.

1 is a block diagram of a facsimile apparatus according to an embodiment of the present invention.

2 is a control flowchart for preventing a blank sheet transmission according to an embodiment of the present invention.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. First, in adding reference numerals to the components of each drawing, it should be noted that the same reference numerals are used for the same components, even if displayed on different drawings. In describing the present invention, when it is determined that a detailed description of a related known function or configuration may unnecessarily obscure the gist of the present invention, the detailed description thereof will be omitted.

The configuration of the facsimile apparatus according to the embodiment of the present invention will be described with reference to FIG. 1, and the controller 10 controls the overall operation of the facsimile apparatus according to the control program stored in the ROM 26. The network control unit (NCU) 12 connects the telephone line to the modem 14 under the control of the controller 10, detects an incoming ring, and provides the received ring to the controller 10. The modem 14 demodulates a modulated signal input through the NCU 12 and modulates a signal to be sent to the telephone line through the NCU 12. OPE (Operating Panel) 16 is composed of a plurality of keys for setting or commanding the functions provided by the facsimile, and provides the control unit 10 with key data by pressing the keys. In addition, the OPE 16 has a display window for displaying the current operating state of the facsimile under the control of the controller 10. When the transmission or copy mode is set, the scanner 18 scans a document supplied under the control of the controller 10 and provides it to the controller 10. The printer 20 prints the received image data or the scanned image data under the control of the controller 10. The sensor 22 checks various states of the facsimile apparatus and informs the controller 10. The insertion of the original to be transmitted is also detected by the sensor 22. The ROM 24 stores a control program executed by the controller 10. The RAM 26 temporarily stores data generated by performing a function provided by the facsimile device. The RAM 26 also receives memory of image data received when a recording sheet runs out while receiving a fax document.

As shown in FIG. 2, a process of preventing the original of a blank paper from being transmitted in the facsimile apparatus according to an embodiment of the present invention.

The white paper transmission preventing process of FIG. 2 is a process of receiving and setting a reference number of blank white lines by a user, detecting and counting white line lines from image data scanned according to a user's transmission request, and counting the white line lines. When the number of the white lines is greater than the set number of white lines, an error sound is output and a method of accurately inserting an original is printed in the document; and if the normal image data line is detected before the white lines or more are detected, the count value is determined. It is a process of resetting.

Hereinafter, an embodiment according to the present invention will be described in detail with reference to the control flowchart shown in FIG. 2 with reference to the above-described configuration of the facsimile.

The controller 10 detects whether the user inserts the document to be transmitted in the standby state (step 210) through the sensor 22 in the standby state (step 210). If the insertion of the document is detected, the controller 10 proceeds to step 214. When the controller 10 proceeds to step 214, the control unit 10 sets a count value n for counting the number of white line lines scanned to "0" and sets a reference white line number k for determining whether a white line line or more of a predetermined line is scanned. . The setting of the reference blank line number k requires the user to input the reference blank line number to set a predetermined value input by the user as the reference blank line number. When the setting of the count value n and the setting of the reference number of blank lines k are completed, the control unit 10 proceeds to step 216 and detects whether the key for requesting the start of the original is pressed by the user. If the press of the key for starting the original transmission is detected, the controller 10 proceeds to step 218. In step 218, the controller 10 controls the scanner 18 to start scanning the inserted document. In step 220, the controller 10 determines whether scanning of a waste paper is completed. The scanner 18 divides the length of a document corresponding to one page into lines at predetermined intervals, scans the divided lines in units of lines, and outputs line data. The line data means image data scanned and input in units of lines. If it is determined in step 220 that the scanning of the waste paper is not completed, the controller 10 proceeds to step 222. When the controller 10 proceeds to step 222, the controller 10 determines whether the line data output in step 218 is line data corresponding to the blank line (hereinafter, referred to as "blank line data"). If it is determined in step 222 that it is not the blank line data, the process proceeds to step 234 and resets n to "0" and returns to step 218. On the other hand, if it is determined in step 222 that the blank line data, the control unit 10 proceeds to step 224 to increase the count value n by one and proceeds to step 226. When the controller 10 proceeds to step 226, the controller 10 compares the increased count value n with the reference number of blank white lines k set in step 214. If it is determined in step 226 that the increased count value n is smaller than the set reference blank line number k (n <k), the process returns to step 218 to scan the next line. However, if it is determined in step 226 that the increased count value n is greater than or equal to the set reference white paper number k (n≥k), it is determined that the inserted original is blank in step 212, and the original is inserted incorrectly in step 228. . The method of notifying the erroneous insertion displays a message indicating that a specific error tone or an original is inserted incorrectly on the display window provided in the OPE 16. In addition, when data regarding a method of accurately inserting an original is recorded in the ROM 24, a method of reading data on the method of correctly inserting an original in the ROM 24 and printing the data through the printer 20 is described. It can be implemented to announce wrong insertion. After notifying the erroneous insertion of the original document in step 228, the control unit 10 stops the transmission of the document and proceeds to step 236 to switch to the standby state. When the blank line data is not detected in step 222, the reset of n to “0” is to determine whether the blank line is continuously scanned by the reference blank line number.

On the other hand, if it is determined in step 220 that the scanning of a document corresponding to one waste paper is completed, the process proceeds to step 230 and modulates the scanned waste paper data through the modem 14 and transmits the data to the receiving side facsimile apparatus. When the transmission of the data corresponding to the waste paper is completed, the control unit 10 proceeds to step 232 and detects whether there is a document to be scanned next through the sensor 22. If it is determined in step 232 that there is a document to be scanned next, the process proceeds to step 234 to reset n to "0" and returns to step 218 to scan the document corresponding to the next page. If it is detected in step 232 that there is no original to be scanned through the sensor 22, the control unit 10 determines that all the originals to be transmitted are normally transmitted, and blocks the call loop by controlling the NCU 12 in step 236. Switch to standby.

The present invention automatically stops the transmission of the original even if the user inserts the original incorrectly and informs the user so that the original can be reinserted and transmitted, thereby preventing the mistake of sending the original in the original transmission as well as the function of the facsimile apparatus. Even for beginners who are not familiar with it, the facsimile machine can be used easily.
