How to Recognize Copy Paper Sizes in the Bypass Tray in the Electronic Copy Device

The present invention relates to copy paper size recognition of the bypass tray in the electronic copying apparatus. In particular, by allowing the user to set the copy paper size of the bypass tray, the electronic copying apparatus recognizes the size of the copy paper and adds various types to the bypass tray. The present invention relates to a copy paper size recognition method of a bypass tray in an electronic copy apparatus that enables a function.

In general, when copying various originals (documents or books, etc.) using an electronic copying device, when a small amount of copying or a predetermined size of copying paper is required to make a quick copying, a copying paper supply method using a manual tray is recommended. If you want to make a copy by using a lot of copies or copy paper of a specified size frequently used, copy it by using the copy paper supply method by the automatic tray.

By the way, when using the copy paper supply method by the bypass tray, the copy paper sensor and the paper width sensor mounted on the bypass tray detects the size of the copy paper, but can not detect the exact size, Since the copy paper first fed from the bypass tray detects the size of the copy paper using the time that passes through the sensor, the copy paper cannot be detected at all. do.

If the paper width sensor is not installed, the size of the copy paper loaded in the bypass tray cannot be detected at all, so the copy paper size is forced to the maximum, and scanning at the maximum size when copying is performed. When the platen cover of the copying apparatus is open, the non-image portion without the original is judged to have formed an image, and thus scanning to the front side of the platen glass wastes toner and power unnecessarily.

Therefore, when the user copies using the bypass tray in the conventional electronic copying device, the electronic copying device cannot recognize the size of the copy paper loaded in the bypass tray. Since various additional functions such as functions cannot be used, only the function required by the user can be manually set and copied, or only the original itself is copied.

As described above, when copying the copy paper to the bypass tray in the conventional electronic copying device, the copy paper is not recognized and thus the unnecessary part is scanned, causing unnecessary waste of power and toner. There is a problem in that it does not provide various additional functions required for copying.

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and an object thereof is to store copy paper size data corresponding to each copy paper size number for setting the copy paper size in an electronic copy apparatus, and When copying using the bypass tray, the user can input the copy paper size number, so that the electronic copying apparatus can recognize the size of the copy paper and provide various additional functions in the bypass tray.

A feature of the present invention for achieving the above object is, in the electronic copy apparatus, in the copy paper size recognition method of the manual tray, the manual tray is selected by the user, the copy paper can be copied if the paper is properly loaded in the manual tray. Displaying a message; Receiving a copy paper size number from the user, storing corresponding copy paper size data, and recognizing the stored copy paper size data as the copy paper size loaded in the bypass tray; A third step of performing a copy operation using the recognized copy paper size when a copy function including various additional functions is selected by the user after the second step; And a fourth step of automatically resetting the copy paper size data for a next user after a predetermined time elapses after the copying operation is finished.

The second process includes a first step of receiving a specific button from the user; Receiving a copy paper size number from the user; A third step of judging whether a confirmation button for confirming that the copy paper size number has been correctly input is input; A fourth step of repeating the operation of the first step if the confirmation button is not input in the third step and receiving the copy paper size number again; When the confirmation button is input in the third step, the copy paper size data corresponding to the copy paper size number is stored in a register, and the copy paper size data stored in the register is recognized as the copy paper size loaded in the bypass tray. And a fifth step.

On the other hand, the fourth process is a first step of checking whether the copy job for the copy number selected by the user is finished while performing the copy job; A second step of displaying a copy paper supply message and repeating the operation from the first step if the copy job is stopped while the copy job is not finished in the first step; A third step of displaying a copy possible message by going to a copy standby state when the copy job is finished in the first step; A fourth step of checking whether a predetermined time for resetting the copy paper size data has elapsed; A fifth step of automatically resetting the copy paper size data for a next user when a predetermined time elapses in the fourth step; And a sixth step of automatically resetting the copy paper size data by performing the operation of the fifth step when the copy paper sensor is turned off in a state in which the predetermined time has not elapsed in the fourth step.

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

In the electronic copying apparatus according to the present invention, a configuration for recognizing copy paper size of the manual tray is shown in FIG. 1. The copy paper sensor 11, the memory unit 12, the CPU 13, And a console unit 14 and a liquid crystal display unit 15.

The copy paper sensor 11 is mounted on the bypass tray, and is switched according to the presence or absence of copy paper for the bypass tray so that the CPU 13 can recognize whether the copy paper is supplied.

The memory unit 12 stores copy paper size data corresponding to the copy paper size number, and stores a program and various guide messages for controlling and controlling all operations of the electronic copy apparatus.

The CPU 13 performs a control processing operation in accordance with a program stored in the memory unit 12. The CPU 13 recognizes various button values applied from the console unit 14 to control the processing of various copying jobs and to copy the spread to the manual tray. It recognizes the paper size, controls various displays on the liquid crystal display unit 15, and stores copy paper size data in a register provided therein for a predetermined time.

The console unit 14 has various function buttons for copying an original and a number button for inputting numbers (0 to 9). The function buttons include specification selection buttons and automatic paper selection for setting various specifications. It consists of an additional function selection button for setting various additional functions such as a function, an automatic magnification selection function, and a split copy function.

According to the control of the CPU 13, the liquid crystal display unit 15 displays various guide messages, a specification setting state, a function setting state, and the like of the corresponding electronic copying device so that the user can visually check.

In the electronic copying apparatus according to the present invention configured as described above, a method for recognizing a copy paper size of a manual tray is described in detail with reference to the flowchart of FIG.

First, the CPU 13 judges whether the manual tray is selected by operating the specification selection button provided in the console unit 14 (step S11), so that the automatic tray is not selected. If it is selected, the copy function by the automatic tray is executed under the control of the CPU 13 according to the program stored in the memory unit 12 (step S23).

By the way, if the manual tray is selected by the user in step S11, the CPU 13 checks whether the copy paper sensor 11 mounted on the manual tray is turned on to check whether the copy paper is properly loaded. If it is determined (step S12) that the copy paper sensor 11 is not turned on, a guide message requesting the supply of copy paper from the memory unit 12 is extracted and displayed on the liquid crystal display unit 15 so that the user can bypass the manual tray. The copy paper is made to be supplied (step S24), and the flow returns to step S12 to perform a repeating operation.

If the copy paper sensor 11 is turned on in step S12, the CPU 13 extracts a copyable message indicating that copying is possible from the memory unit 12, and displays the copyable message on the liquid crystal display unit 15 to display the user. Enable copying using the bypass tray (step S13).

At this time, the CPU 13 judges whether a specific button for setting the size of the copy paper loaded in the bypass tray is input by operating the specification selection button provided in the console unit 14 by the user (step S14). If the specific button is not input by the user, the copy function by the conventional bypass tray is performed (step S25).

On the other hand, when a specific button is input by the user in step S14, the CPU 13 receives the copy paper size number inputted by operating the numeric buttons provided in the console unit 14 by the user, and the liquid crystal display unit 15 ) (Step S15).

Thereafter, the CPU 13 judges whether a confirmation button for confirming that the function button provided in the console unit 14 has been operated by the user to confirm that input of the copy paper size number has been properly input (step S16), If the confirmation button is not input by the user, the process returns to step S14 to repeat the operation so that the copy paper size number for the size of the copy paper loaded in the manual tray can be re-entered.

When the confirmation button is input by the user in step S16, the CPU 13 can recognize the size of the copy paper loaded in the bypass tray using the copy paper size number input by the user. Copying paper size data stored in the memory unit 12 corresponding to the copy paper size number is taken out and stored in a register of the CPU 13 itself, and copy paper size data stored in the register is loaded in the manual tray. It recognizes as a paper size (step S17).

After step S17, the CPU 13 recognizes that various buttons of the console unit 14 are input by the user, and performs a copy operation according to a program stored in the memory unit 12, in which the user As (13) can recognize the size of the copy paper, not only the general copy function by the manual tray but also various additional functions can be selected so that the copy job can be handled by simple button operation without manual processing. (Step S18).

Then, the CPU 13 checks whether the copy job for the copy number selected by the user is finished while performing the copy job according to the copy function selected by the user (step S19). If the electronic copy device stops the copy job while the copy job for the selected copy number is not finished, the CPU 13 recognizes that the copy paper loaded in the bypass tray is not enough and from the memory unit 12. A guide message requesting copy paper supply is drawn out and displayed on the liquid crystal display unit 15 to allow the user to supply copy paper in the bypass tray (step S26), and the flow returns to step S18 to repeat the operation.

Then, if the copy job for the number of copies selected by the user in step S19 is terminated, the CPU 13 enters a copy standby state for the next copy job as the copy job ends, and the next copy job is executed. After extracting a copyable message from the memory unit 12 and displaying it on the liquid crystal display unit 15 (step S20), it is confirmed whether a predetermined time for automatically resetting the copy paper size data stored in its own register has elapsed. (Step S21).

At this time, the CPU 13 continuously checks whether a predetermined time has elapsed, and when a predetermined time elapses, the copy paper size data stored in its register for the next user, that is, the copy paper recognized by the CPU 13. By automatically resetting the size, when the next user makes a copy using the electronic copy device, it is possible to prevent unwanted copying from being performed by the recognized copying paper size or various errors occurring during the copying (step S22). ).

On the other hand, when a predetermined time has not elapsed in step S21, the CPU 13 determines whether the copy paper sensor 11 mounted on the bypass tray is turned off (step S27), and the copy paper sensor 11 If it is not off, the process returns to step S21 to repeat the operation, and if the user of the electronic copy device removes the copy paper loaded in the bypass tray for another copy job, the copy paper sensor 11 is turned off. If so, the operation of step S22 is performed (step S27), and the recognized copy paper size is automatically reset.

As described above, in the present invention, when a user inputs the size number of the copy paper when copying using the manual copy tray of the electronic copying apparatus, the electronic copying apparatus recognizes the size of copy paper supplied to the bypass tray and adds various types. By providing the function, it is possible to reduce unnecessary power and waste of toner and improve the use efficiency of the electronic copying device.
