1 is a block diagram of a facsimile to which the present invention is applied.

2 is a flowchart showing a process of sorting and storing the last called party number according to the present invention.

3 is a flowchart illustrating a redialing process according to the present invention.

The present invention relates to a redial processing method in a document transmission / reception system. In particular, a redial user's intention (voice call or document transmission) is checked to determine a corresponding counterpart number (telephone number or facsimile number). It is about how to call.

In general, the redial function that has been used in the facsimile is to redial without re-entering the same phone number when attempting to make a voice call or a document transmission call and then failing or reconnecting to the previous call line. The user only needed to enter the key once to provide convenience to the user. However, the local fax user called only the phone number of the last dialed counterpart without determining whether the user intended to send a document. In other words, pressing the redialing key in the facsimile calls the other party's phone. In this case, the intention of the local user who attempted the redialing can be divided into two types. One of them is the case of calling the telephone number for the purpose of talking with the other station, and the other one is the case of calling the fax number for the purpose of sending document with the other station. As described above, the user may try two reasons for redialing, but in the conventional facsimile, there is a problem that the redial is attempted without regard to the same intention as the former. In addition, even if a dedicated fax line was established in the other country, it was inconvenient to send documents only by telephone.

Accordingly, an object of the present invention is to provide a method of increasing the convenience of a user by checking a user's intention to transmit a document or a voice call even when redialing and calling a corresponding fax or fax number of a corresponding station.

In order to achieve the above object, the present invention identifies and stores whether a call number calling a counterpart is for a facsimile or a phone, and stores the same, and if a document is set in a local facsimile feeder upon detecting a redialing key input. Determine, and call the facsimile number or telephone number of the counterpart according to the determination result of the document setting, and determine whether to open the call with the counterpart station and perform a document transmission or a voice call when the call path is connected. do.

Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

1 is a configuration diagram of a facsimile to which the present invention is applied, and includes a OPE (OPERATIONAL PANEL) 30 for displaying an operation state of the facsimile, including a numeric key and a redialing key, and a central processing unit 10 described later. Generating a dialing pulse of the call number by the numeric key and calling the corresponding station facsimile, generating a dialing pulse corresponding to the call number of the redialing key, and calling the corresponding station facsimile, Modem 50 for detecting CED tone or DIS (0000 0001: digital signal) indicating whether the other station fax is automatically received by the numeric key, and CED tone or DIS (0000 0001 :) in modem 50. If a digital signal is detected, the call number by the numeric key is recognized as a facsimile number. If the CED tone or DIS (0000 0001: digital signal) is not detected, the call number is detected. Recognized by a telephone number, and operates under the control of the central processing unit 10 and the central processing unit 10 to control the overall operation required for the document transmission / voice call classification service according to the document transmission / voice call classification service program A network control unit (NCU) for forming a call loop of a telephone line and interfacing the modem 50 and the coral of the telephone line, and a first controller for storing the telephone number under the control of the central processing unit 10. A ROM storing a dialing buffer, a second redialing buffer storing the facsimile number, the document transmission / voice call classification service program and various data generated when the document transmission / voice call classification service program is executed. The memory unit 20 having various memories such as RAM, the remaining amount of recording paper, and whether or not the document is set in the feeder are detected. A sensor unit 80 for generating a call and applying the same to the central processing unit 10, a scanner 40 for converting an image of the document into digital image data and providing the same to the central processing unit 10; It consists of a speaker 90 for generating an alarm by the control signal of the central processing unit 10.

FIG. 2 is a diagram illustrating a process of selectively storing a called party's number for a telephone or a facsimile and selectively storing it in a first redialing buffer or a second redialing buffer of the memory unit 20 shown in FIG. will be.

The last dialed (or redialed) partner station number is conventionally stored in one redialing buffer, but is expanded to two in the present invention. The first redialing buffer stores the telephone number of the last called party for the purpose of a call, and the second redialing buffer stores the last called station fax number for the purpose of sending a document. That is, the second redialing buffer receives the call number of the corresponding station only when a CED tone (2100 Hz), which is a signal indicating whether the other station is in an automatic reception state, or a DIS (000 0001) signal, is detected. Store as a facsimile number.

In step 2a, when the call number by the numeric keys is input through the OPE 30 of FIG. Control to generate The modem 50 calls a counterpart station by generating a dialing pulse corresponding to the call number and sending it to the telephone line through the NCU 60. In step 2b, the central processing unit 10 checks whether the other station is busy. As a result of the test, if the call is not in progress, the process moves to 2c, and if the call is in progress, it proceeds to process 2e. In step 2c, the central processing unit 10 checks whether the counter station is in the facsimile automatic reception state. This check depends on whether a CED tone (2100 Hz) or DIS (0000 0001: digital signal) is detected in the modem 50. As a result of the check, if the CED tone or DIS is detected, the call number is recognized as a facsimile number. The process proceeds to step 2d to store the facsimile number in the second redialing buffer and ends.

On the other hand, if the CED tone or DIS is not detected in step 2c, the central processing unit 10 recognizes the call number as a phone number for the purpose of the call, and transfers to step 2e to store it in the first redialing buffer. And exit.

FIG. 3 is a flowchart illustrating a process of processing a redialing operation by using telephone numbers and facsimile numbers respectively stored in the first redialing buffer and the second redialing buffer in FIG. 2.

In step 3a, when the redialing key is input through the OPE 30 of FIG. 1, the CPU 10 detects this and transitions to step 3b. In step 3b, the sensor unit 80 checks whether a document is set in the feeder under the control of the central processing unit 10, and if the document is set in the feeder, generates a setting signal to the central processing unit 10. Is authorized. When the CPU 10 detects the setting signal, it determines that the user has a willingness to send a document, and proceeds to step 3c to read the facsimile number finally stored in the second redialing buffer and then the modem 50. Is applied. The modem 50 generates a dialing pulse corresponding to the facsimile number under the control of the central processing unit 10 and transmits it to the telephone line through the NCU 60. In step 3d, it is checked whether the other party's facsimile having the facsimile number is busy. As a result of the check, if the call is not busy, the process proceeds to the process 3e, and the document set in the feeder is automatically sent to the other station's facsimile, and the call is immediately terminated.

On the other hand, if the setting signal is not detected in step 3b, the user's intention is determined to the voice call, the central processing unit 10 transitions to step 3f to read the phone number finally stored in the first redialing buffer and then To the modem 50. The modem 50 generates a dialing pulse corresponding to the telephone number under the control of the central processing unit 10 and transmits it to the telephone line through the NCU 60. In step 3g, it is checked whether the other party's telephone having the telephone number is busy. As a result of the check, if the call is not busy, the process proceeds to 3h to perform the operation required for the phone call and immediately terminates the call.

As described above, the present invention determines user's intention of document transmission or voice call according to the presence or absence of document setting at the time of redialing and automatically calls the other station with the fax number or telephone number finally stored in each redialing buffer. The advantage is that the document can be automatically sent to the destination fax.
