The data down-sized based on a certain ratio is printed on a recording paper through a printer(18) controlled by a printer drive(17) based on a page-per-pager method.

Description

Reduced copy method for multifunction device {METHOD FOR REDUCTION COPY IN MULTI FUNCTION PERIPHERAL}

The present invention relates to a reduced copy method of a multifunction printer, and more particularly, to a reduced copy method of a multifunction printer which reduces data transmitted from a scanner or an external facsimile and divides and prints the data on a single sheet of paper.

Recently, office-automation devices such as printers, scanners, and facsimiles have become widespread, and more high-performance products have been developed in an effort to expand the unique functions of each device. As a result, the production cost of the product has risen, increasing the economic burden on the consumer. For this reason, a complex device (hereinafter, referred to as a 'multifunctional') that integrates devices used independently of each other has emerged. Somehow could be solved.

The multifunction device is equipped with printing means, scanning means, and information transmission means such as a modem, which combines the functions of a printer and a facsimile as well as a scanner and a copier through a single device. It is a device that can be implemented.

Such a method of reducing and copying data received from a scanner or an external device in the multifunction apparatus is a page per page method of printing a sheet of paper one by one by reducing a document of one page as shown in FIG. 1.

However, according to such a conventional multi-function reduced copying method, since one page of originals reduced at a specified ratio is printed one sheet on one sheet of paper, the size of the reduced data is small, that is, printed on one sheet of paper. If there is more free space than data, it causes waste of recording paper. In addition, in the case of extracting and extracting the recording paper on which the reduced data is printed using a knife or scissors, the user is required to repeatedly perform a series of operations on all pages.

Accordingly, an object of the present invention is to solve such problems, and an object of the present invention is to waste paper waste by dividing a plurality of pieces of data received from a scanner or the outside into one sheet of paper according to a reduction ratio specified by a user. To provide a reduced copy method of the multifunction device to prevent the.

Is shown.

Referring to FIG. 2, the central processing unit 10 is a control means for controlling the entire system, and in particular, controls to copy and split the data reduced according to a preset ratio onto one sheet of recording paper.

The scanner module 11 reads image data, and a shuttle method, a sheet-feed method, or a flat-bed method may be used as a method of reading image data.

The image processor 12 may perform shading and gamma correction, dot per inch (DPI) conversion, edge emphasis, and error diffusion on image data input from the scanner module 11. )).

The image memory 13 is a buffer memory for image data processing used by the image processing unit 12 as a buffer for image processing.

The rasterizer 14 rasterizes the image data read into the vertical blocks, and in particular, according to a preferred embodiment of the present invention, the rasterizer 14 reduces the image data to be divided and copied in the horizontal direction and to the predetermined ratio. It rotates by 90 degrees and rasterizes the image data to be divided and copied.

The system memory 15 is composed of an EPROM in which an entire system program is stored, a static RAM (SRAM) for processing system data, and a dynamic RAM (DRAM), which is a user memory.

The Enhanced Capabilities Port (ECP) 16 is a module for bidirectional parallel interface with a computer (PC) in accordance with IEEE 1284, and transmits scanned image data to a computer (PC) or prints data from the computer (PC). This is the part to receive.

The printer driver 17 controls the printer 18 to perform printing on the recording paper, such as print head FIRE & ENABLE control, carriage return motor phase and position control, document data processing and a line for supplying printing paper. It controls the feed motor. The printer 18 jets ink in accordance with data under the control of the printer driver 17 in an inkjet manner and performs an actual printing operation.

The modem 19 and the LIU 20 are interface means for transmitting and receiving with an external facsimile.

The operation of the present invention configured as described above will be described in detail with reference to FIGS. 2 to 4.

If the user selects a predetermined reduced copy ratio in the multifunction apparatus and sets the reduced copy mode (S301), the CPU 10 checks the reduced ratio stored in the system memory 15 ( S302).

The central processing unit 10 controls the scanner module 11 to scan an original and store the original in the system memory 15 (S303), check whether the checked reduction ratio is 50% or more (S304), and confirm the result 50%. If abnormal, the scanned data is reduced according to the checked predetermined ratio (S305).

The data reduced according to the predetermined ratio is printed on the recording paper in a page per page manner through the printer 18 driven by the control of the printer driver 17 (S306).

On the other hand, if the reduction ratio of the check result in step 304 (S304) is not more than 50%, the scanned data stored in the system memory 15 is reduced according to the checked predetermined ratio (S307).

The central processing unit 10 stores the reduced data in the system memory 15 according to the checked predetermined ratio (S308), and detects the width of the reduced data stored in the system memory 15 (S309).

The CPU 10 compares whether the width of the detected reduced data exceeds a preset value (S310). Here, the preset value is a reference value for determining whether to copy the reduced data horizontally on a single sheet of paper or to make a partial copy by rotating 90 degrees.

As a result of the comparison, when the width of the detected reduced data exceeds a preset value, the CPU 10 checks whether the next page exists (S311), and if the next page exists, controls the scanner module 11 to control the next page. Scan (S312).

When the next page starts to be scanned, the rasterizer 14 rotates the reduced data of one page stored in the system memory 15 by 90 degrees, and stores the data rotated by 90 degrees in the system memory 15 (S313). ).

The central processing unit 10 prints the reduced data rotated 90 degrees stored in the system memory 15 on the recording paper as shown in FIG. 4A through the printer 18 driven by the control of the printer driver 17. (S314).

When printing of the reduced data rotated 90 degrees with respect to one page is completed, the central processing unit 10 scans from the scanner module 11 and then reduces the data of the page in the same manner as described above and rotates by 90 degrees. In S314, the area of the recording paper on which data rotated by 90 degrees is printed is divided and printed (see Fig. 4A).

At this time, if the scanning of the next page is not completed even after the printing of the reduced data rotated 90 degrees for one page is completed, the step until the scanning of the next page is completed and the printing operation for the reduced data rotated 90 degrees is performed. In 314 (S314), the recording paper on which the reduced data rotated by 90 degrees with respect to one page is printed is not discharged and remains in the standby state.

Therefore, if the data reduced in the ratio set by the user cannot be divided and copied horizontally onto the recording paper, the copied data is divided into the recording paper by rotating the reduced data by 90 degrees.

On the other hand, if the detected width of the detected reduced data exceeds the preset value compared to the preset value 310 (S310), if the detected width does not exceed the preset value, the CPU 10 checks whether the next page is present. (S315).

As a result of the check, if the next page exists, the next page is scanned and stored in the system memory 15 in the same manner as described above (S316), and the scanning data stored in the system memory 15 is reduced according to a preset reduction ratio. Stored in (15) (S317).

When the reduction of the data corresponding to the two pages is completed, the rasterizer 14 divides the reduced data corresponding to the two pages stored in the system memory 15 in the horizontal direction by the control of the CPU 10. Rasterized to suit the scheme and stored in system memory 15.

The central processing unit 10 is reduced according to a predetermined ratio and prints the data stored in the system memory 15 on the recording paper as shown in FIG. 4B through the printer 18 driven by the control of the printer driver 17. (S318).

In operation 315 (S315) of determining whether a next page exists, the method branches to step 318 (S318) of printing the reduced data according to a predetermined ratio stored in the system memory 15 when the next page does not exist.

Therefore, it is possible to divide and copy the data reduced in the ratio set by the user horizontally onto the recording paper.

As described above, in the detailed description of the present invention, specific embodiments have been described, but various modifications are possible without departing from the scope of the present invention. Therefore, the scope of the present invention should not be limited to the described embodiments, but should be defined by the claims below and equivalents thereof.

As described above, according to the reduced copy method of the multifunction apparatus according to the present invention, since the multiple pieces of data received from the scanner or the outside are divided and copied onto one sheet of recording paper according to a reduction ratio specified by the user, paper waste is prevented. In the case of extracting and extracting a plurality of pieces of data printed on a recording sheet, there is an advantage that a series of operations can be performed more simply.
