The key input unit 100 scans a 3 × 4 dial key, a fax transmission document when sending a fax document, detects an edge of the scanned document paper, checks the fax paper size, and selects a specific paper size selected by the user. It consists of a number of keys that allow you to operate the Autofit key and a number of other options to input a key input signal for enlarging or reducing the scanned image to fit the destination fax machine. Can be.

After scanning the fax document to be transmitted, the scanner 130 provides the scanned image data to the controller 110.

The ECP 160 is a module for a Bi-Direction Parallel Interface with a PC based on IEEE 1284. The ECP 160 transmits data scanned through the scanner 130 to a PC or receives data transmitted from the PC. To output through the printer 170.

The first memory 120 stores image data scanned by the scanner 130 under the control of the controller 110, and the second memory 140 stores a program for driving the entire system.

The controller 110 provides a scanning control signal to the scanner 130 when a user inputs an autopit key signal from the key input unit 100 for autofit fax transmission and selects a fax transmission paper size to be converted.

The image data of the fax document scanned from the scanner 130 is stored in the first memory 120 according to the control signal.

In addition, the controller 110 detects an edge of the image data stored in the first memory 120 to detect the size of the paper for the fax transmission document, and then detects the size of the detected paper and the size of the selected paper. Will be compared.

As a result of the comparison, when the size of the detected paper and the size of the selected paper are the same, the image data is transmitted as it is via the modem 180 and the LIU 190 to the dialed destination fax without enlargement or reduction of the image data.

However, when the size of the detected paper and the size of the selected paper are not the same as each other, the image data stored in the first memory 120 is enlarged or reduced in accordance with the size of the selected paper and temporarily stored in the first memory 120. Done.

As described above, when the reduction or reduction of the image data is performed, the control unit 110 displays the dialing request message for the telephone number of the destination fax on the display unit 110.

If the user dials the destination fax number, the enlarged or reduced image data temporarily stored in the first memory 120 is provided to the modem. Here, the control unit 110 stores the image data scanned by the scanner 130 in the first memory 120, detects the paper size for the fax transmission document through the edge detection of the stored image data, And an image processing unit (not shown) for performing enlargement or reduction conversion.

The modem 180 codes the enlarged or reduced image data provided from the control unit 110 and then is provided to the LIU 190, and the LIU 190 receives the coded fax transmission image data provided from the modem 180. It will be sent to the destination facsimile device via the PSTN line.

A detailed operation of the document transmission apparatus of the facsimile apparatus according to the present invention having such a configuration will be described.

First, when the user wants to transmit the fax data by enlarging or reducing the fax document, after loading the fax transmission document into the facsimile device, the autopit key signal of the key input unit 100 and the paper for enlarging or reducing the document Select the size. Here, the key input unit 100 may include a key for selecting paper (A4, B5, LETTER, etc.) for enlargement or reduction of a document.

When the autopit key signal and the fax transmission document paper size value are input from the key input unit 100, the controller 110 provides a scanning control signal to the scanner 130.

The scanner 130 loads and scans the loaded fax document according to a scanning control signal provided from the controller 110.

The scanned image data is provided to an image processing unit (not shown) in the control unit 110.

The image processor in the controller 110 stores the image data provided from the scanner 130 in the first memory 120.

When the scanned image data is stored in the first memory 120, the image processing unit in the controller 110 detects an edge of the image data stored in the first memory 120 to detect the loaded fax document paper size.

When the size of the loaded document sheet is detected, the controller 110 compares the size of the sheet selected by the user.

As a result of the comparison, when the detected paper size and the selected paper size are the same as each other, the controller 110 reads the scanned image data stored in the first memory 120 and provides it to the modem 180.

The modem 180 codes the image data provided from the controller 110 and transmits the coded data to the destination facsimile device through the LIU 190.

However, when the size of the detected paper and the size of the selected paper are not the same as each other, the control unit 110 reads image data stored in the first memory 120 according to the size of the selected paper, and selects the size of the paper selected by the user. After the enlargement or reduction to fit the size, it is temporarily stored in the first memory (120).

As described above, when the reduction or reduction of the image data is performed, the control unit 110 displays the dialing request message for the telephone number of the destination fax on the display unit 110.

When the user dials the number of the destination fax milling device through the key input unit 100 according to the dialing request message displayed on the display unit 110, the control unit 110 temporarily enlarges or reduces an image stored in the first memory 120. The data is read and provided to the modem 180 via the data bus.

The modem 180 codes the enlarged or reduced image data provided from the control unit 110 and then provides the coded image data provided to the LIU 190, and the LIU 190 transmits the coded fax transmission image data provided from the modem 180. It will be sent to the destination facsimile device via the PSTN line.

A method of transmitting a document of a facsimile apparatus according to the present invention corresponding to the above operation will be described step by step with reference to FIG. 2.

First, as shown in Figure 2, it is determined whether the auto-pit key is input from the user (S101).

If the Auto Fit key is not input, the fax data is transmitted to the destination fax machine in the same manner as the conventional fax data transmission method without expanding or reducing the fax data (S114).

On the contrary, when the Auto Fit key is input from the user in step S101, it is determined whether the size of the fax document is enlarged or reduced, that is, the size of the fax transmission paper is selected (S102). Here, the fax paper sizes include A4, B5, LETTER paper, and the like.

Here, when the user inputs the Autofit key, a message for selecting an enlarged or reduced sheet may be displayed on the display unit 150 shown in FIG. 1, and the enlarged or reduced sheet may be selected as shown in FIG. 1. Although a selection key may be provided in the key input unit 100, the paper type information may be displayed on the display unit 150 to select a desired paper from among the displayed paper types.

If the fax transmission paper size is selected from the user, after loading the fax document (S104), the scanned fax document is scanned and stored in the memory (S105).

Then, the edge of the image data stored in the memory is detected to detect the size of the fax document paper loaded by the user (S105), and the detected fax document paper size is compared with the paper size selected by the user in step S102 ( S106).

As a result of the comparison, if the size of the detected paper and the size of the selected paper are not equal to each other, the image data stored in the memory is read according to the size of the selected paper, and then enlarged or reduced to fit the size of the paper selected by the user. Temporary storage in the memory (S107).

In this way, when the reduction or reduction of the image data is made, the dialing request message for the telephone number of the destination fax is displayed (S108).

Subsequently, when the user dials the number of the destination fax milling device according to the displayed dialing request message (S109), after coding the enlarged or reduced image data temporarily stored in the memory (S110), the destination facsimile device through the PSTN line. It will be transmitted to (S111).

However, when the destination fax number is not dialed from the user in step S109, the time is counted, and when the counting time passes, the image data stored in the memory may be deleted (S112 and S113).

Alternatively, if a dialing is not possible even after a certain time has elapsed, a warning message may be displayed or a warning sound may be generated. If dialing is not possible even after a warning message or a warning sound occurs, the image data stored in the memory is deleted.

In addition, in the step S106, if the detected paper size and the size of the paper selected by the user are the same size, data is transmitted in the same manner as the general facsimile data transmission method, and thus the detailed description thereof will be omitted.

As a result, the data transmission device and method of the facsimile apparatus according to the present invention, after scanning a fax transmission document when sending a fax document, detects the edge of the scanned document paper, checks the fax paper size, and selects the user. It has an Autofit function that enlarges or reduces the scanned image to fit the specific paper size and sends it to the destination fax machine.

The document sending apparatus and method of the facsimile apparatus according to the present invention as described above, after scanning a fax transmission document when sending a fax document, by detecting the edge (edge) of the scanned document paper, and confirms the fax paper size, Automatically enlarges or reduces the scanned image to fit the specific paper size you select and sends it to the destination's facsimile device, which makes it difficult for the user to fax the enlarged or reduced copy and then fax the copied or enlarged document.
