BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a facsimile system, and more particularly, to a facsimile apparatus and a surface symmetric image transmission method capable of converting an image to be transmitted into a surface symmetric image.

In general, when an image is transmitted using a facsimile, there is a case where it is necessary to switch the image left and right as necessary. For example, when copying the contents of the film and then transmitting the copied contents, sometimes copying the contents of the film may be copied in a reversed state. In this case, if the copied contents include characters, the left and right sides can be immediately noticed, but if only the image data is included, it is often difficult to grasp them.

Therefore, if the fax machine has the function of inverting and sending the image when the original drawing that has been copied is left and right reversed, the problem of switching the film from side to side can be solved. In the design of a certain product, there may be a case in which the left-right reversed, that is, the plane symmetrical drawing is required to check and examine the convenience of use of the external handle.

Accordingly, an object of the present invention is to provide a facsimile apparatus and an image transmission method capable of selectively transferring an image which is face symmetrical with an original image.

In order to achieve the above object, another facsimile apparatus according to the present invention includes a main board for controlling image transmission of the facsimile, an operation panel connected to the main board to transmit a user's command, and displaying an operation state by the main board; A thermal head unit that prints an image upon reception of an image under control of a board; a contact image sensor unit that reads an image as an electrical code upon transmission of an image under the control of a main board; and setting of a transmission document, transmission time, A facsimile device equipped with a sensor unit that detects the end of the document, the opening of the facsimile housing and provides a detection signal to the main board, and a handset connected to the main board. Face symmetrical transmission selection switch to set the symmetrical transmission when selecting the surface symmetrical image transmission function under control of the motherboard And further comprising a latch representing the taegap provides a facsimile apparatus comprising the image transfer plane symmetry.

In addition, the transmission method according to the present invention applied to the facsimile apparatus configured as described above, the first step of moving to the contact image sensor unit when the document is set in the tray; A second step of determining whether the image symmetric transfer function of the image is selected by the surface symmetric transfer selection switch unit, if the selection is performed, storing the surface symmetric state value in the latch unit, and performing dialing; Wow; A third step of driving a feeding motor to feed an original and reading an image line by line with a contact image sensor and converting the image into a digital signal; The latch unit checks whether the shift state value is stored, and if the shift state value is stored, converts the image data into face symmetric image data, encodes the image data, and transmits the image data. Transmitting a fourth step; A fifth step is performed to perform image transmission for the remaining set originals and to end.

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

1 is a block diagram of a conventional facsimile apparatus.

As shown in the drawing, a conventional facsimile apparatus includes a main booth (1) for controlling image transmission and reception of the facsimile, and a main board (1) connected to the main board to transmit a user's command and display an operation state by the main board (1). The operation panel 2, the thermal head portion 4 (TPH) that fronts the image upon reception of the image under the control of the main board 1, and the image upon transmission of the image under the control of the main board 1 A contact image sensor unit 5 (CIS) to be read by a code, and a sensor unit 6 which detects the setting of a transmission original, transmission time, end of the original, and opening of the facsimile housing to provide a detection signal to the main board 1. ), A handset 7 connected to the main board 1.

The basic operation according to the image transmission of the conventional facsimile apparatus configured as described above will be described with reference to FIG.

2 is a flowchart of processing according to image transmission of a conventional facsimile apparatus.

First, when setting the document to be sent to the feeder, the sensor unit 6 detects the setting of the document and sends a detection signal to the main board 1 to drive the feed motor (10 to 12). Once driven, the set original is moved to the contact image sensor unit 5 (hereinafter referred to as CIS) (13). When the user dials to the destination, the user judges whether the operation is in the transmission mode or the copy mode. If the operation is specified in the copy mode, the selected document is copied and terminated. Restart the motor (14-17).

Thus, the original is read through the CIS 5 line by line and transmitted to the motherboard 1 as an analog signal (17, 18). The motherboard 1 converts the input analog signal into a digital signal and converts it. The digital signal is encoded using the encoding rule (19, 20).

The coding rule is shown in FIG.

The coded data is transmitted from the main board 1 by using a telephone line (21), and the procedure is repeated until the sensor unit 6 receives a detection signal indicating the end of the original (22). When the signal at the end of the original is input to the main board 1 (23), it is determined whether the original to be transmitted is set (24), and if it is set, the above steps (17 to 23) are repeated. If it is not set, the paper feed motor is stopped to end the image transfer operation (25).

4 is a configuration diagram of a facsimile apparatus according to the present invention, in which, reference numeral 8 denotes a surface symmetric transfer selection switch unit, 9 denotes a latch unit, and the same reference numerals as in FIG. Indicates.

As shown in the figure, the facsimile apparatus according to the present invention, in the conventional configuration shown in FIG. 1, is connected to the main board 1 and the plane symmetric transfer selection switch for setting the plane symmetry function when transferring the image in the plane symmetry A section 8 and a latch section 9 for indicating a surface symmetric transfer state value at the time of selecting the surface symmetric image transfer function under control of the main board 1 are further provided.

The process of the method for transmitting the plane symmetric image of the facsimile apparatus according to the present invention configured as described above will be described in detail with reference to FIG.

5 is a flowchart of a process of the plane symmetric image transmission method according to the present invention, which is performed by a control program mounted on a main board.

In the same figure, the same reference numerals as those in FIG. 2 are performed in the same manner as in FIG.

In order to avoid duplication of explanation, the description will focus on the processing procedure added by the present invention. If the document has been moved to the CIS 5 (13), it is checked by the surface symmetric transfer selection switch section 8 whether the image symmetric transfer function is selected (26), and if the surface symmetric transfer function is selected, the latch unit 9 ), The surface symmetry state value is stored (27) and the dialing is performed (14). If the surface symmetric transfer function of the image is not selected, the dialing is immediately performed (14).

If image information is converted into a digital signal to transmit the image 1 line signal (19), it is checked whether or not a surface symmetric state value is stored in the latch section (9). As a result of the inspection, if the surface symmetry state value is stored in the latch unit 9, in order to encode the digital image signal, the image data of each line is rearranged in the order of transmitting the image data of the pixel read last. After performing image symmetric image coding in which the image data of the rightmost pixel is arranged in the order of the leftmost data and obtaining the surface symmetric image data (29), the data is transferred (21), and the image symmetry is applied to the latch unit 9. If the magnification value is not stored, the image information is encoded by the data value of equal magnification (20), and then transmitted (21).

FIG. 6 is a diagram illustrating a procedure of encoding face-symmetric image data. When the CIS 5 reads an image, the image is read into the left pixel part, and thus the data of the last address stored in the buffer becomes the rightmost image data of the read line. . Therefore, as shown in the drawing, when the image data at the last address of the right-most storage line buffer of the rightmost image data is transferred to the transfer buffer in order, the image data is transferred to the transfer buffer as the image data reversed from the original image. Will be.

In addition, according to the present invention, it is also possible to designate only a part of the transmission image and transmit it in surface symmetry.

Therefore, the present invention made as described above has an effect of transmitting an image whose left and right are reversed according to a user's needs.
