Description

How to automatically set / cancel call forwarding according to the presence of paper in the fax that provides call forwarding service

The present invention relates to a call forwarding of a facsimile, and more particularly, to a method of automatically setting / clearing call forwarding according to the presence or absence of paper in a facsimile that provides a call forwarding service function.

A typical function of the facsimile apparatus is a document sending / receiving function that allows a sender and a receiver to send and receive a document. When the sender places the original to be sent on a pedestal and dials the receiving telephone number, the facsimile apparatus reads the original and performs the protocol specified by the dialed receiving side fax to transmit image data. Then, the receiving side fax receives the image data received according to the protocol communication after receiving the ring and prints it on the recording paper. The receiving side confirms the contents by viewing the printed recording paper. However, since the facsimile apparatus does not receive image data when the recording paper for receiving the paper falls, the sender attempts to transmit repeatedly or judges the facsimile failure as the facsimile machine displays a communication error.

As described above, the conventional facsimile has a problem in that it cannot receive image data at the time of no-paper.

In order to solve the above problems, an object of the present invention is to forward calls according to the presence or absence of paper in a facsimile that provides a call forwarding function so that image data can be received from another registered facsimile when no image data is received due to no-paper. It provides a method to automatically turn on / off.

In order to achieve the above object, the present invention provides a method for automatically setting / release call forwarding according to the presence or absence of no-paper in a facsimile receiving a call forwarding service function from an exchange, wherein the facsimile forwarding setup code and release code are previously set in the facsimile. After registering the call forwarding telephone number, the call forwarding setup code and the call forwarding telephone number are automatically transmitted to the exchange through the public telephone network when the no paper is set, and the call forwarding is established when the no paper is released. The call forwarding release code is automatically sent to the exchange through the call forwarding.

If no call forwarding setting bit is set, the call is transmitted through a public telephone network. Set up call forwarding by automatically sending forwarding setup code and call forwarding phone number to the exchange, and release call forwarding release code automatically through the public telephone network when the no-paper release.

1 to 5 will be described in detail a preferred embodiment of the present invention.

In the facsimile that provides the call forwarding service function according to the present invention, when the automatic call forwarding / setting according to the presence or absence of paper is required, the code for the call forwarding setting / release should be sent to the exchange. The code / release code was made changeable when necessary. The code change method will be described in detail with reference to FIG. 2. First, in step 101, the CPU 10 presses a code change request key from the user through the OPE 14. If the code change request is requested, the process proceeds to step 102. If there is no code change request, the process ends. In step 102, the central processing unit 10 receives the change of the call forwarding setting code through the OPE 14, and if the call forwarding setting code change is input, the process proceeds to step 103. Proceed to step 201. In step 103, the central processing unit 10 controls the memory 12 to read a pre-registered call forwarding setup code. Thereafter, in step 104, the central processing unit 10 displays the previously registered call forwarding setup code on the display device of the OPE 14, and then proceeds to step 105. In step 105, the central processing unit 10 receives a call forwarding setup code to be changed from the user through the OPE 14. Then, in step 106, the central processing unit 10 checks whether the change code input is completed, and proceeds to step 107 when the change code input is completed, and returns to step 105 when the change code input is not completed. Continue to enter In step 107, the central processing unit 10 controls the memory 12 and ends after storing the changed call forwarding setting code. In step 201, the central processing unit 10

If the call forwarding release code change is input through the OPE 14 and the call forwarding release code change is input, the process proceeds to step 202. If the call forwarding release code change is not input, the process ends. In step 202, the central processing unit 10 controls the memory 12 to read the pre-registered call forward release code. Thereafter, in step 203, the central processing unit 10 displays the read previously registered call forward release code on the display device of the OPE 14, and then proceeds to step 204. In step 204, the central processing unit 10 receives an incoming call forward release code from the user through the OPE 14. Then, in step 205, the central processing unit 10 checks whether the change code input is completed, and proceeds to step 206 if the change code input is completed, and returns to step 204 if the change code input is not completed. Continue to enter the code. In step 206, the central processing unit 10 controls the memory 12 to save the changed call forwarding release code and ends. On the other hand, when the call forwarding service function is provided by the CO switch, the call forwarding setup code currently used by KT is '* 88', and '# 88 *' is used as the call forwarding release code. Therefore, the call forwarding setup code / release code is stored in the memory in advance when the facsimile product is sold and does not need to be registered or changed by the user separately. However, in the case of a private exchange, the call forwarding setup code / release code is provided by the Korea Telecom. In the present invention, the call forwarding setting code and the call forwarding release code may be changed.

The call forwarding setting code and the call forwarding release code can be arbitrarily changed in the facsimile providing the call forwarding service function, and then the call forwarding setting mode is automatically set according to the present invention by selecting the call forwarding setting mode. The call forwarding setting mode selection and the call forwarding release mode selection method will be described with reference to FIG. 3. In step 301, the central processing unit 10 presses the call forwarding setting mode selection key from the user through the OPE 14. If the call forwarding setting mode key is pressed, the process proceeds to step 304, and if the call forwarding setting mode key is not pressed, the process proceeds to step 302. In step 302, the central processing unit 10 checks whether the call forwarding release mode key is pressed, and if the call forwarding release mode key is pressed, proceeds to step 303, and if the call forwarding release mode key is not pressed, the setting mode / release Wait for the mode key input. If the call forward release mode is selected, the central processing unit 10 resets the call forward setting bit indicating that call forwarding has been released in step 303. If the call forward release mode is selected, the fax does not provide the call forwarding service function. Meanwhile, when the call forwarding setting mode is selected in step 301, the central processing unit 10 receives the call forwarding phone number through the numeric key of the OPE 14 in step 304. The call forwarding phone number may be inputted by one call forwarding phone number or a plurality of call forwarding phone numbers. Then, in step 305, the central processing unit 10 checks whether the input of the call forwarding phone number is completed, and proceeds to step 306 if the input is completed, and returns to step 304 if the input is not completed. Continue typing. In step 306, the central processing unit 10 controls the memory 12 to store the call forwarding telephone number input by the user in the memory. Thereafter, in step 307, the central processing unit 10 sets a bit BIT of a predetermined address indicating that call forwarding is set.

If the user selects the call forwarding setting mode and stores the call forwarding phone number in advance, and sets the call forwarding setting bit, the facsimile can perform the call forwarding service function. According to the present invention, image data cannot be received due to no-paper. When the call forwarding is set in the state, and the method of releasing the call forwarding when releasing the no-paper will be described with reference to FIGS. 5A and 5B, first, in step 401, the CPU 10 performs sensing of a sensor (not shown). If the detection of the no-paper is detected, if no paper is detected, the process proceeds to step 402. If the paper exists, the call forwarding program according to the present invention is terminated. In step 402, the central processing unit 10 examines the call forwarding setting bit and proceeds to step 403 when the call forwarding setting bit is set, and releases the call forwarding when the call forwarding setting bit is reset. In mode, the program according to the present invention is terminated. In step 403, the central processing unit 10 controls the LIU 20 to on-line the public telephone network, and then proceeds to step 404. In step 404, the central processing unit 10 controls the memory 12 to read the call forwarding setting code and the call forwarding phone number stored in the memory 12. Assume that the call forwarding setup code is '* 88' as an example in FIG. 4 and the call forwarding phone number is '123-4567'. Then, in step 405, the central processing unit 10 automatically dials the call forwarding setting code '* 88' and transmits it as a DTMF signal to the public telephone network, and in step 406, the call forwarding phone number '123-4567' is also dialed. It transmits DTMF signal to public telephone network. When call forwarding is established by the above process, the central processing unit 10 controls the LIU 20 to off-line the public telephone network in step 407. When the call forwarding is set through the public telephone network as described above, the central processing unit 10 displays the call forwarding setting state indicating that the call forwarding is set through the display device of the OPE 14 in step 408. The call forwarding setting state display may display, for example, a predetermined message on the LCD of the OPE 14 or a predetermined LED is turned on. When call forwarding due to no-paper is set in the facsimile, image data reception is performed in the facsimile in which the call is forwarded. Then, when the no-paper is released and the image data can be received, the call forwarding set in the facsimile must be released. This image data reception state check is performed by a sensing operation of the paper detection sensor. In step 409, the central processing unit 10 checks whether the no-paper is released, and if the no-paper is released, proceeds to step 410. If the no-paper is not released, the central processing unit 10 continuously sets the call forwarding to receive image data. To be performed on the forwarded fax. In step 410, the central processing unit 10 controls the LIU 20 to on-line the public telephone network, and then proceeds to step 411. In step 411, the CPU 10 controls the memory 12 to read the call forwarding release code stored in the memory 12. Assume that the call forwarding release code is '# 88 *' as an example in FIG. Then, in step 412, the central processing unit 10 automatically dials '# 88 *', which is a call forwarding release code, and transmits the DTMF signal to the public telephone network. When the call forwarding is released by the above process, the central processing unit 10 controls the LIU 20 to off-line the public telephone network in step 413. When the call transfer is released through the public telephone network as described above, the central processing unit 10 displays the call transfer release state indicating that the call transfer has been released through the display device of the OPE 14 in step 414. The call forward release state indication may be displayed by, for example, displaying a predetermined message on the LCD of the OPE 14, or by turning off the LED indicating the call forward setting.

As described above, the present invention has an effect of automatically receiving a call transfer when the image data cannot be received due to the no-paper from the facsimile, so that the image data can be received from another fax when the image data cannot be received due to the no-paper. have.
