BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a control apparatus and method for a manual feeder of a copying machine, and more particularly, to a control apparatus and method for a manual feeder capable of continuously copying sheets of paper.

In the manual feeder of the conventional copier, when the manual feed door is opened, values such as the number of copies, image density, and magnification data set on the display panel on the copier's operation panel are evacuated to the memory of the copier's electronic control unit. When the data is closed, the original data value is returned to the previous copy state, and when the conventional manual feeder is examined, one copy is initially set, but it is set to be used in the manual feeder. This conventional technology is inconvenient in use, and has recently been configured to use a plurality of copy papers. However, when the copy paper is set in the multipurpose feeder, the end of the copy paper set by the user is arbitrarily set and the copy paper is set too deep or too far in some cases, causing frequent malfunctions in the copying operation. There was this. In other words, the width direction of the copy paper can be adjusted by using a paper guide, etc., but there is no function of adjusting the copy paper's position in the longitudinal direction. In addition, when the copy start switch is pressed, the main motor is driven, and inefficient operation is performed in which the scanner operation light is turned ON for the maximum size value irrespective of the loaded paper size. Accordingly, since the initial positions of the feed tips are different, there is a problem that it is difficult to maintain a constant copy position.

Accordingly, an aspect of the present invention is to provide a control apparatus and method for a continuous copying manual feeder configured to solve the problems of the prior art.

In order to achieve the above object, the present invention provides a key data interface means connected to an operating panel of a copier to interface data values (copy number value, image density data, magnification data, etc.) of a copier operating state. A serial communication terminal connected to the key interface means for controlling the continuous copying operation of the manual feeder according to data on the operating state of the copier input from the operating panel of the copier; and an address to the central control means. A memory feeder connected to a bus, an input / output port connected to the central control means and a memory means by a data bus, a manual feed guidance sensor connected to a buffer of the input / output port to sense opening and closing of the manual feed door, and the input / output Paper presence connected to the port through a buffer to detect the presence of paper on the paper table A sensor is connected to the input / output port through a buffer and the solenoid driving means receives the control signal from the central control unit to drive the solenoid. The control device is applied to the control device and detects that the manual feed door is opened. A first step of storing the number of sheets of paper set in the memory means; a second step of driving the main motor according to the ON of the copy start key after performing the first step; and an initial position of the stopper after performing the second step. A third step of holding and resetting the solenoid, a fourth step of driving the solenoid according to the driving signal of the solenoid after performing the third step, and a feeding roller as the driving signal of the paper feed roller is input after performing the fourth step. Step 5, and if the paper set on the document table has been copied after the step 5 is performed, the paper feed roller and solenoid If OFF to shut down the entire operation and the paper copy was left OFF, only the paper feed roller was composed of a control method performed by a processing procedure of the sixth step of transitioning to the fourth step.

Hereinafter, with reference to the accompanying drawings will be described an embodiment of the present invention;

1 is a perspective view of a continuous copy manual feeder mechanism under the control of the present invention, in which 1 is a paper table, 2 is a lever bracket, 3 is a solenoid, 4 is a paper presence sensor, 5 is a detection piece, and 6 is selected. (pick-up) roller, 7 stopper, 8 body bracket, 9 feed roller, 10 spring, 11 index finger support, 12, 13 shaft, 14 friction pad, 15 transmission gear, 16 children Gears 17 denote copier side plate brackets and 18 denote electromagnetic clutches, respectively.

Looking at the overall operation of the manual feeder operated by the control of the present invention.

When the paper is set on the paper table for continuous copying by manual feeding, the detection piece 5 is rotated while being supported by the detection piece support 11 by pushing the lower portion of the detection piece 5 where the paper is located by its own weight. Therefore, the upper part of the detection piece 5 in the light blocking area of the light receiving part and the light emitting part of the sensor 4 exits from the light blocking area, and the sensor 4 detects the presence of paper. The stopper 7 located by its own weight rotates with the shaft 12 as a hinge, but the rotation of the stopper 7 is limited by the body bracket 8 until the copying operation is started. This allows tip alignment.

When the solenoid 3 is operated together with the copy start signal, the lever bracket 2 supported by the spring 10 and fixed to the side plate bracket 17 is moved downward and supported by the lever bracket 2. 12) is also moved downward by its own weight. When the shaft 12 is moved downward, the selection roller 6 and the stopper 7 fitted to the shaft 12 are also moved downward so that the selection roller 6 is positioned at the top of the set paper and the stopper 7 is Since the body bracket 8 is moved to the bottom, no further rotation restrictions are applied, so that copy paper can be fed into the copier.

At the same time, the electromagnetic clutch 18 is also turned on together with the copy start signal, so that the transmission gear 15 and the idle gear from the feed roller 9 rotate as the shaft 13 rotates and the shaft 13 rotates. The electoral roller 6, which has received power through the 16, selects the set paper one by one and transfers it to the paper feed roller 9 so that the paper enters into the copier one by one through the paper feed roller 9 and the friction pad 14. Let's do it.

When the copy start signal is turned off, the solenoid 3 is turned off, and the lever bracket 2 is returned to its original position. Accordingly, the shaft 12, the selection roller 6 fitted to the shaft 12, and the stopper 7 are returned to their original positions. Is restored. By the way, since the original position restoration of the stopper 7 is difficult in the rotated state at the time of paper feeding, once again the solenoid 3 is turned on / off for a short time and the impact to the stopper 7 returns to its original position by its own weight. To be restored.

Since the manual feed mechanism is configured and operated as described above, continuous copying becomes possible even in the operating state of the manual feed.

2 is an operation timing diagram for showing the procedure of the operation relationship of the manual feeder.

When the copy start pulse signal comes in, after a certain time, the main power source of the copier is operated, and when the operation signal to the manual feed is input, the operation signal of the solenoid 3 is first input, and the solenoid 3 is driven to select the roller. When 6) is moved down enough to select an original, the signal is supplied in the order in which the operation signal of the paper feed roller 9 is applied.

As shown in the figure, the control device of the continuous copy manual feeder of the present invention is connected to an operating panel of the copier to provide data values (copy number value, image density data, magnification data, etc.) of the copier operation state. A key data interface unit 21 for interfacing with a serial communication terminal is connected to the key interface unit 21 to control the manual feeder according to the data on the operating state of the copier input from the copier's operation panel. A control unit 22, a memory unit 23 connected to the central control unit 22 by an address bus, an input / output port 24 connected to the central control unit 22 and the memory unit 23 by a data bus, A manual feed guidance sensor 26 connected to the input / output port 24 through the buffer 25 to detect the opening and closing of the manual feed door, and a buffer table connected to the input / output port 24 through the buffer 25. A document presence sensor 4 for detecting the presence or absence of an original and a buffer 25 connected to the input / output port 24 to receive a control signal from the central controller 22 to drive the solenoid 3. The solenoid drive part 27 is comprised. Here, the central control unit 22 is composed of a CPU in which control software is embedded.

Meanwhile, since the components constituting the present invention, that is, the configuration of the key data interface 21, the input / output port 24, the solenoid driver 27 are well known in the art, detailed description thereof will be omitted.

4 is an overall flowchart of the control method of the continuous copy manual paper feeder of the present invention.

First, by detecting whether the manual feed guide is open (31), if it is opened, the paper data is placed in the paper table (1) of the copier, and then the number of copies to be copied is input as the key data input / output interface unit (21). The data value is inputted to the central control unit 22, stored in the memory unit 23 (32), and returned if not opened. After inputting the number of sheets, it is determined whether the number of sheets inputted is more than the allowable maximum number of sheets (33). If the number of sheets is higher, it is set to the maximum number of sheets (34) and an alarm signal is displayed (35). Set to the set value (36). Then, it is determined whether the copy is possible (37). If it is not possible, it returns. If it is enabled, the copy start key is turned on when the copy start key is turned on (38), and the main motor of the copier is driven (39).

After the main motor is driven, it is again determined whether the manual feeder is kept open (40). Otherwise, it is determined whether the solenoid 3 is initialized (41). If the solenoid 3 is initialized, the initial position of the stopper 7 is set (42), and the initial value of the solenoid 3 is set, that is, it is determined to which operation signal to operate (43). In operation 47, it is determined whether the driving flag of the solenoid 3 is set. However, if the solenoid 3 is not initialized, it is determined whether the paper is set (44), and the paper is set to determine whether the driving flag of the solenoid 3 is set (47). Calculate (45) and reset solenoid (3) (46). Here, calculating the sensing time means checking a reference time for determining that there is no paper.

As a result of determining whether the solenoid drive flag is set (47), if it is not set, it returns and if it is set, the solenoid 3 is turned on and waits for the paper feed roller 9 to operate (48). It is judged whether the paper feed roller 9 drive flag is set (50), and if it is not set, it returns and the paper feed roller 9 is driven (51). Then, it is judged whether all the sheets are loaded on the paper table 1 (52). If all are fed, the solenoid 3 is turned off (53). If not, all of them are added and subtracted (54). . Addition of the number of copies possible is a process for displaying on the operation panel how many copies have been copied from the beginning to the present, and subtraction is a process for determining how many copies are left from the value set for copying.

After the calculation process (54), the number of copy setting number and the number of copy completions are the same (55), so if continuous copying is completed, the feed roller (9) and the solenoid (3) are turned off, and then the main motor is turned off (57). . However, if the number of copies set and the number of copies completed are not the same, only the feed roller 9 is turned off (58), and the flow advances to step (50) to determine whether the feed roller drive flag is set.

Therefore, the present invention configured and operated as described above enables continuous copying even by manual copying and solves the problem that a uniform copy image is not formed on the paper due to misalignment of the edges of the paper according to the feeding state. It can be effective.
