BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a facsimile using automatic document feeding (hereinafter referred to as ADF), and more particularly, to a method for automatically ejecting a document in a stop mode.

In general, the facsimile uses the ADF function. When the original is placed on the paper feed surface, the motor is driven by the paper detection sensor so that the original is fed and the original reaches the scan position. The facsimile performs various services such as document transmission and document copying by the user's intention.

The document is automatically fed when the original is placed on the sheet of paper by the user. This is called an ADF function. Thus, the ADF is a function that can be very useful when using a plurality of originals.

In a fax that is automatically fed using the ADF function, the user may cancel the document after loading it at the scanning position. In this case, the fax will display a message prompting the user to remove the document. In this case, the document is automatically discharged when the document is one sheet, and the document is sequentially discharged when the document is multiple sheets. In this case, the user frequently uses a forced method of extracting the original by the top cover open button attached to the front of the facsimile, in addition to the automatic ejection method when the original is several sheets. In addition, there is a problem of waiting until all the documents in the ADF standby state are automatically ejected even after the document is being transmitted or set to the stop mode by the stop key while copying.

Therefore, when the originals are ejected in the ADF, the user is inconvenient due to the time consumption due to the automatic ejection of all originals and the forced physical loss caused by the top cover open button.

Accordingly, it is an object of the present invention to provide a method for discharging an original from a facsimile of the automatic document feeding function for discharging the original of the scanning position by the ADF to the document feeder when the stop mode is entered.

In order to achieve the objects of the present invention, a method for discharging a fax having an automatic document feeding function, wherein the document is discharged to the document feeder when the document is set to the stop mode while the document is automatically fed to the scanning position. It is characterized by consisting of.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. It should be noted that like elements in the figures represent like reference numerals wherever possible.

1 is a diagram illustrating a configuration of a facsimile for carrying out the present invention. The control unit 111 controls the overall operation of the transmission mode, the reception mode, and the copy mode of the facsimile according to a set program. In addition, the control unit 111 may include a program memory and a data memory or may be externally connected as shown by reference numeral 119. The program memory stores the program of the present invention. OPE (Operating Pannel) 112 is composed of a key input means and a display means. The key input means of the OPE 112 generates data of a key pressed by the user to designate each mode and perform an operation of the designated mode, and outputs the data to the controller 111. In addition, the display means of the OPE 112 performs a function of inputting and displaying display data indicating an operation state of the system when the controller 111 performs each mode.

The sensor unit 113 detects the presence or absence of an input document and print paper, and outputs the detected state signal to the control unit 111.

The scanner 114 shifts the input document, scans the original image, and converts the document into digital data. The image processing unit 115 converts and outputs the image signal provided by the scanner 114 into digital data. The print unit 116 prints image data input from the image processing unit 116 on a print sheet when the receiving mode and the copy mode are controlled under the control of the control unit 111. At this time, a print operation is performed by driving the print engine provided in the print unit 116. Under the control of the control unit 111, the modem 117 modulates and transmits the image data output from the image processing unit 115 according to the transmission type, that is, the standard standard of the facsimile, in the transmission mode, and in the reception mode, the encoded data is input through the transmission line. The image signal is demodulated in its original form so that the image processor 115 can process it. The motor unit 120 operates by a motor driving signal generated by detecting when the document is placed on the paper feed surface by the sensor unit 113.

The NCU * Network Control Unit 118 forms a transmission / reception path between the telephone line (Tip, Ring) and the modem 117 under the control of the control unit 111.

2 is a view showing a control flow for manuscript ejection in the pause mode of the fax according to a preferred embodiment of the present invention. Hereinafter, the second drawing will be described in detail with reference to the first drawing.

In step 211, when the user places the original on the document feeder, the sensor unit 113 detects this and outputs a control signal to the control unit 111. Then, the control unit 111 controls the motor unit 120 to drive the motor for the ADF in forward rotation in step 212. Thereafter, the motor is driven in the forward rotation until the document is detected as the scan position by steps 212 and 213. If the user presses the stop key of the OPE 112 when the user wants to cancel the use, the control unit 111 detects this and sets the stop mode. Accordingly, the control unit 111 set to the stop mode in step 214 controls the motor unit 120 in step 216 to drive the motor in reverse rotation. Thus, the motor is driven in reverse rotation until the original is positioned at the original document feeder by steps 216 and 217. Afterwards, the user is able to easily remove the document in the document feeder because the document, which was bitten on the paper feeder, is initially fed due to the motor reverse rotation.

On the other hand, the stop key is not input in step 214, and according to the user's instruction by the OPE 112, the control unit 111 performs a routine for a transmission mode and a copy mode such as to transmit or copy an original in step 111. Accordingly, when the stop key which the user intends to cancel the use of during the transmission mode and the copy mode is applied in step 219, the control unit 111 forcibly ejects the corresponding document engaged with the paper feeder in step 220. Step 221 is shifted to step 216 when the next original of the original is detected at the scan position by the ADF. Thus, due to the reverse rotation of the motor, it is returned to the document feeder engaged with the paper feed at the scanning position. Thus, the user can easily grasp and remove the original by hand.

As described above, when the original is pressed by the roller at the scan position by the ADF in the present invention, when the stop mode is set, the original document held by the roller is moved backwards so that the user can easily remove the original by hand. Can be. Thus, it is possible to reduce the waiting time until all of the above originals are discharged to the document discharge pedestal, and to reduce the physical force of opening the top cover.
