Description

Selective Printing Method Using Subscriber Identification Information in Fax Machine

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a facsimile apparatus, and more particularly, to a selective printing method which can save a fax recording paper.

In general, the facsimile device has a configuration as shown in FIG. The document scanned by the document reading unit 6 is widely used as an image data communication device that converts the original document to the other side through a public telephone network and simulates the original document through the recording unit 8 such as a printer in response to a signal transmitted from the other side. Known. Such a facsimile apparatus is linked with a telephone to transmit and receive the original data as well as to perform a voice call through a connected telephone. Therefore, in a typical home, one telephone and one facsimile are connected to each other without using a telephone separately, and the image data reception mode and the voice call mode are alternately used as necessary.

The central processing unit 4 in the facsimile apparatus periodically checks the ring signal to determine whether there is an external call. When a ring signal is detected and a CNG tone indicating that the other party's facsimile machine is sending out original data is received by a protocol, the facsimile device performs an operation for receiving image data under an image data reception mode. In this case, no call path is formed with the handset of the telephone connected to the facsimile, but a call path is formed between the internal modem and the telephone line of the public telephone network. On the other hand, when the ring signal is detected and the voice of the other party other than the CNG tone is received, the device operates in the voice call mode. In this case, a communication path is formed between the handset of the telephone connected to the facsimile and the telephone line of the other party, and no communication path is formed between the internal modem and the telephone line of the public telephone network.

Meanwhile, CCITT T.30, an international telephony advisory committee, recommends various signal standards and protocols for data communication between data transmission and reception devices, and manufacturers of devices are designing internationally for compatibility of devices. It is true. A mutual protocol for data communication of a general facsimile device is recommended in CCITT T.30, and is generally performed by performing four phases. That is, after the call line is established between the apparatus on the sending side and the facsimile apparatus on the receiving side and the CNG tone is transmitted, the operation of providing the called station identification (called station identification) to the transmitting side in the first state is performed. In the second state, operations in which the receiving side sends a capacity ID to the transmitting side, the transmitting side sends a command information and a status / training signal to the receiving side, and the receiving side provides a receiving ready acknowledgment signal (CFR) to the transmitting side Is performed. In addition, in the third state, the operation of transmitting the message, which is the data of the transmitting side, is performed at the set communication rate. In the fourth state, when all the messages are transmitted from the transmitting side, the end signal of the message is transmitted and the reception is performed. The operation of sending a signal confirming this to the transmitting side is performed.

In the facsimile apparatus as described above, the image data received under the image data reception mode is generally printed on a recording sheet. Thus, the user of the facsimile apparatus reads the contents printed on the recording sheet and recognizes the message of the other party. However, the printed recording paper may be necessary for the user or may not be so. If not necessary, for example, when an unknown party accidentally sends a manuscript through the user's own facsimile phone number for the purpose of advertising, only the user's recording paper is wasted. It can be seen that this waste of recording paper occurs because the facsimile apparatus prints it on the recording paper every time image data is received.

As described above, since image data to be received is necessarily printed in the related art, there is a problem of causing waste of recording paper.

Accordingly, an object of the present invention is to provide a selective printing method in a facsimile apparatus that can solve the above-mentioned conventional problems.

Another object of the present invention is to provide a selective printing method which can save recording paper used in a facsimile apparatus.

1 is a circuit block diagram in a facsimile apparatus applied to the present invention.

2 is a control flowchart of selective printing according to an embodiment of the present invention.

According to an aspect of the present invention for achieving the above object, the image data printing method in the facsimile apparatus, storing the subscriber identification information received from the calling party in the identification area of the memory, and in the image data receiving mode Demodulating analog image signals received through a public telephone network, converting them into digital image data, and storing the image data in a storage area of the memory; and checking the subscriber identification information on the recording paper only if the information is authorized. Characterized in that it has a step of printing.

Hereinafter, a circuit and a method according to a preferred embodiment of the present invention will be described with the accompanying drawings. Like reference numerals in the accompanying drawings indicate that the same configuration and function as possible. In the following description, the detailed items for such configurations are described in detail in order to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention may be practiced without these specific details. In addition, the features of the basic elements of well-known facsimile devices and configurations of known circuit blocks are not described in detail in order not to obscure the present invention.

First, Fig. 1 shows a circuit block diagram in a facsimile apparatus applied to the present invention. The analog signal received by the modem (not shown) is demodulated into digital image data and then stored in the memory unit 10 through the processing unit 4. The stored data is directly provided to the recording unit 8 for printing or displayed on the display unit 14 and then provided to the recording unit 8 for selective printing.

2 is a control flowchart of selective printing according to an exemplary embodiment of the present invention, and includes 20 to 23 steps. The subscriber identification information received at the calling party is stored in the identification area of the memory by the execution of step 20. In the twenty-first step, the central processing unit 4 demodulates the analog image signal received through the public telephone network in the image data reception mode, converts the analog image signal into digital image data, and stores the analog image signal in the storage area of the memory. In a twenty-second step, the subscriber identification information goes to a twenty-third step only if it is checked and authorized information. Step 23 is a step of selectively printing the image data on recording paper. In addition, printing can be performed manually by displaying data stored on the display and scrolling one by one by a user's key input.

As described above, according to the present invention, the recording paper can be saved by selectively controlling the printing of the facsimile apparatus.
