The present invention relates to an enlargement and reduction method in a copying machine, and in particular, to a copying method capable of shifting as well as shifting.

In general, the copier has a system as shown in FIG. 1, and its configuration includes a ROM 15 for storing various system operation programs and a program for controlling the overall operation of the copier and outputting the data in accordance with an address signal, and the ROM. RAM 20 for storing and outputting various data as an address signal, storing and outputting various data as an address signal as needed, and data input keys required for various operations. When the key is pressed, the keyboard 25 outputs the corresponding data in the machine language, and when the power is initially supplied, a system operating program is loaded from the ROM 15 to form an initial preparation state of the copier, and the keyboard 25 Receives data, loads the program stored in the ROM 15 by giving an address signal, and closes the entire operation of the copier. A lens driving motor power by receiving the lens driving data output from the CPU 10, a first input / output device 30 receiving the lens driving data from the CPU 10, and outputting the lens output data to the outside. The lens driving unit 35 to generate a lens drive, the lens driving motor 40 to generate a lens driving torque by driving the lens driving motor power of the lens driving unit 35, and the lens driving torque of the lens driving motor 40 Receiving and outputting the scanner driving data from the lens 45 and the CPU 10 receiving the reciprocating motion, and outputting the scanner motor driving power by receiving the output of the second input / output 50. Receiving and scanning the scanner driving unit 55 and the scanner driving torque of the scanner motor 60 and the scanner motor 60 to generate a scanner driving torque by rotating the scanner driving before the scanner driving unit 55 It consists of a scanner 65.

In addition, in the copier having the above configuration, the conventional variation (enlarging or reducing the copy original in both the longitudinal and the lateral directions) is realized in the flow as shown in FIG. 2, and the operation thereof will be briefly described.

First, the CPU 10 scans the keyboard 25 in step 201 to check whether the user selects the shift function. If the user selects the shift function, the CPU 10 receives the change ratio input by the user through the keyboard 25 in step 202 and checks whether it is a reduced magnification or an enlarged magnification in step 203.

If it is determined in step 203 that the reduced magnification is determined at step 203, the CPU 10 proceeds to step 204 and inputs the rotational speed value of the scanner driving motor 60 to the scanner driver 55 to scan the scanner driving motor 60. The speed of the scanner 65 is determined by setting the number of revolutions. And when selecting the reduction magnification, the speed of the scanner is adjusted faster than the scanner speed in the normal state. After completing the step 204, the CPU 10 moves the position of the lens 45 to the position where the image on the drum is reduced in step 205. If it is determined in step (203) that it is not a reduced magnification, the CPU 10 recognizes that it is an enlarged magnification. In step 206, the scanner rotation speed value is input to the scanner driver 55 as in step 204. The speed of the scanner 65 is determined. At this time, the enlarged copy is used, so the scanner 65 is slowly adjusted. In step 207, the lens 65 is moved in the opposite direction to step 205 above.

However, the conventional variable copying method as described above has a disadvantage in that it is not possible at all when the enlargement of the longitudinal or lateral direction is impossible to satisfy, and thus cannot satisfy various needs of the user.

Accordingly, it is an object of the present invention to provide a copying method that can be used as well as a doubler for reducing and expanding only the longitudinal or transverse direction.

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

Figure 3 is a flow chart according to the present invention, the first step of checking whether the shift mode, and in the first step check only the shift mode temporary longitudinal direction in the first step in the longitudinal direction only the lens position is fixed to 1: 1 copy position scanner In the second process of adjusting the speed according to the reduction or enlargement mode, and in the second process, when the variation is only in the longitudinal direction, only the lateral direction is checked except in the longitudinal direction. The third step of fixing the lens position in accordance with the reduction or enlargement mode, and checking the variation only in the lateral direction in the third step. The fourth step of adjusting the speeds of the two and the first step is not shift mode or if there is a temporary copy start input after performing the second to fourth steps, the scanner is moved to the scanner return position. It consists of a fifth step of returning after which copper.

FIG. 4 is an exemplary view of the present invention. FIG. 4A is a manuscript, FIG. 4B is a view in which the figure 4A is reduced only in the lateral direction, and FIG. 4C is a view in which the figure 4A is enlarged in the lateral direction only. 4d is a longitudinal reduction of FIG. 4a, and FIG. 4e is a longitudinal extension of FIG. 4a, and FIG. 4f and 4g are examples of reduction and enlargement as in the prior art.

5 is an original scanning and latent image, (x) is a diagram in which the scanner time-divisions the original to be scanned, and (y) is a latent image formed on the drum according to the position of the lens when the scanner scans the original. Is a view showing.

Therefore, an embodiment of the present invention will be described based on the above configuration.

First, the principle of the biasing function of the present invention will be described briefly. In FIG. 5 (x), the scanner 65 scans the document while moving in the t direction. If the rotational speed of the drum coincides with the linear speed of the scanner 65, the unit of the image of the original image on the drum is united. The division can be set based on time. The distance of this divided part is called d. When the scanner 65 maintains the normal speed and the lens 45 is in a 1: 1 magnification position, the image of the original forms a latent image on the drum in its actual size. On the contrary, when the speed of the scanner 65 is maintained at a normal speed and the position of the lens is moved to the reduced position as shown in FIG. 5 (y), only the longitudinal direction is maintained while maintaining the horizontal image of d on the drum. The reduced image is formed. As such, the movement of the lens 65 does not affect the longitudinal direction at all, and affects only the lateral image. On the contrary, the moving speed of the scanner 65 affects only the image in the longitudinal direction irrespective of the transverse direction. If the rotating speed of the drum is made constant and the moving speed of the scanner 65 is increased, the constant speed on the drum is increased. Since the document is scanned more than the normal state with respect to the distance, the scanner speed is increased in the case of reduction, and slowing down the scanner speed in the case of enlargement can enable longitudinal shifting.

In the present invention, the principle as described above is shifted to perform the partial shift. First, in step 301, the CPU 10 checks whether the current mode is the shift mode. In this case, if the user selects the shift, the CPU 10 searches for the longitudinal direction in step 302, and then receives the magnification input by the user through the keyboard 25 only in the longitudinal direction. Form it in 1-fold position.

The CPU 10 checks whether the magnification received in step 302 is a reduced magnification or an enlarged magnification by fixing the lens 45 to a 1: 1 magnification position. -If the magnification is magnified, and the magnification is magnified, set the scanner speed to be (normal speed + magnification -100) to determine the scanner speed. However, if it is not the longitudinal direction in step 302, the CPU 10 checks whether the horizontal direction is selected only in step 303, receives the magnification input by the user in step 309, and then measures the scanner speed. 1: Fix at 1x speed. In this state, if the magnification input in step 309 is a reduction magnification or enlargement magnification, the CPU 10 moves the position of the lens 45 to the reduction position, and if the magnification is temporary, Move the position of 45 to the enlarged position.

In step 303, the CPU 10 determines that the shift mode is a predetermined multiple of both the horizontal and the vertical, not the single copy, when the vertical direction is not the vertical direction in step 308. A magnification corresponding to the variation is received from the user. If the value of the magnification is magnification or reduction magnification in step 315, check if the magnification is reduced, and move the lens 45 to the reduction position and set the scanner speed to (normal speed + 100-magnification). do. In addition, if the magnification value input in step 314 is an enlarged magnification, the CPU 10 branches to step 318 in step 315 to move the lens 45 to an enlarged position, and then the scanner speed is normal. Adjust speed + scale-100).

After setting the lens 45 and the scanner speed 65 as described above, when the copy start key is input, the scanner is driven and scanned to execute a single shift or shift and end. When the copy start key is inputted from the keyboard 25 without any processing when the shift mode is not selected in step 301, the scanner 65 is driven to scan and end.

As described above, the present invention has the advantage that the user can input the data through the keyboard 25 so that not only the copying machine but also the copying machine can satisfy various needs of the user and improve the added value of the copying machine.
