The present invention relates to a method for reducing a transmission time of a facsimile, and more particularly, to a method for reducing a transmission time of a facsimile, which reduces the transmission time of an original by 1/2 compared to the conventional method.

In the conventional case, regardless of the font size and complexity of the sender, it is a general method to select and transmit in the mode of small character (3.85 per mm), small character (7.7 per mm) and small character (15.4 per mm). In the case of simple state of communication, the communication time is much longer unless specially reduced and copied.

In addition, the Matsushita product adopts the technique of compressing and printing on the receiving side, but this method can also reduce the recording paper, but it is impossible to select the function if the receiving side does not know the status of the original document beforehand. There is a problem that takes the same as the existing method.

The present invention has been made to eliminate the above problems, and when the user of the sender determines the complexity of the original and selects the transmission time reduction function, the fax reduces the original transmission time occupying the call line to 1/2. The purpose of the present invention is to provide a method for reducing transmission time.

In order to achieve the above object, the present invention provides a transmitting motor and a receiving motor, a transmitting motor driving means and a receiving motor driving means respectively connected to the motor, and the user sets a general function operation of the fax and a transmission time saving mode of the present invention. Operation means for controlling the controller, input / output buffer means connected to the operation means, transmission motor driving means, and receiving motor driving means, modem and network control means connected to a public telephone network (PSTN) via a line, and the input / output buffer means And central control means connected to the modem and network control means, memory means connected to the central control means, image input means connected to the central control means to scan an image of an original to be transmitted or copied, and the central control means. And image recording means connected to and printing the received image data and the scanned copy image data. In a transmission time reduction of facsimile apparatus way, it sets the set and the transmission mode of the transmission original and the first stage of the transmission request; A second step of determining whether to set a transmission time saving mode; A third step of determining which transmission speed mode is selected when the transmission time saving mode is set to rotate at a higher speed than the motor driving speed of the corresponding mode; And performing a normal transmission operation.

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

1 is a block diagram schematically showing a known general facsimile apparatus as a device to which the present invention is applied.

In the drawings, 1 is a transmitting motor, 2 is a receiving motor, 3 is a control unit, 4 is a transmitting motor driving unit, 5 is a receiving motor driving unit, 6 is a modem and network controller, 7 is an input / output buffer unit, 8 is a central control unit, 9 is An image input unit, 10 represents an image recording unit, and 11 represents a memory unit, respectively.

As shown in the figure, a general facsimile apparatus includes a transmitting motor 1 and a receiving motor 2, a transmitting motor driver 4 and a receiving motor driver 5 respectively connected to the motor, and a user operating a general function of the fax. And an operation unit 3 for setting a transmission time saving mode of the present invention, an input / output buffer unit 7 connected to the operation unit, a transmission motor driver, and a reception motor driver, and a public telephone network PSTN via a line. A modem and network control unit 6, a central control unit 8 connected to the input / output buffer unit and a modem and network control unit, a memory unit 11 connected to the central control unit, and a transmission or An image input unit 9 for scanning an image of an original to be copied, and an image recording unit 10 connected to the central control unit and for printing received image data and scanned copy image data. It's that is to send and receive the external facsimile device and the image information.

2 is a flowchart schematically showing the process of performing the present invention. The user sets the originals to be transmitted, determines the complexity of the originals, sets a transmission time saving mode, and sets a mode such as ordinary and small characters. (20) When the transmission request is made (21), the central control unit 8 determines whether or not the transmission time saving mode is set (22), and if it is not set, performs the transmission operation according to the conventional method. Again, check whether the transmission mode is set to normal, small, or small. If the normal mode is set (23), set the speed twice the actual motor drive PPS (Pulse Per Second). 24) If the small character mode is set (25), it is set at the normal motor drive PPS speed (26), and if neither of the two cases is applicable, the small character mode is recognized and the small character mode is set. The rotor drive PPS speed is set (27) so that the rotational speed of the transmission motor is rotated at a higher speed than the corresponding mode speed in the normal operation, and then the normal transmission operation is performed (28).

However, if the transmission time saving mode is not set in the initialization step (22), the speed bit is set (29 to 33) to drive the transmission motor at the motor speed of the corresponding mode specified in the conventional manner, and then normal transmission is performed. Perform the operation (28)

The reception recording state of the transmission originals transmitted in this manner is shown in Fig. 3, where a shows the printing states of the transmission original and the reception recording paper by the conventional method, and b shows the transmission time saving mode of the present invention. Shows the printing status of the transmitted original and the received recording paper by using.

Therefore, the present invention as described above improves the information transmission efficiency by reducing the transmission time by 1/2 compared to the conventional method, the sender can select the function by viewing the original status, improved the convenience of use, This has the effect of reducing the recording sheet.
