The present invention relates to a reference copy number control method when performing a group mode of an automatic sorting apparatus (hereinafter referred to simply as "Sota") for loading paper discharged from a copying machine or an image forming apparatus.

Generally, Sota has a type of bins in which a plurality of bin trays are moved up and down, and a bin in which many bin trays are fixed and a conveyance guide is moved. Most of them have a sorting function for each page. .

In addition, since the proper stacking capacity of copy paper is significantly smaller than the continuous copy designation number of the copying machine due to the mechanical characteristics of the sota, in the conventional case, the copying by using the page-by-page sorting function (hereinafter, simply referred to as "GROUP MODE") function At the time, the user often designates each tray to exceed the acceptable standard number of copies, which implies a problem such as a discharge jam (JAM) or the like.

In addition, the weight varies depending on the size of the paper being loaded. The load required for moving the bin is changed, so that the larger the paper size is, the smaller the load is, and the amount of static electricity is generated. It was required to change and set the copy paper load appropriately.

The present invention has been made to solve the above-mentioned problems, and in the group mode, by setting the proper storage amount of the sota for each paper size, even if the user exceeds the standard number of sheets, it automatically switches to the standard number of sheets so that smooth paper storage can be achieved. The purpose of the present invention is to provide a method for controlling the number of reference copies when the Sota group mode is performed.

In order to achieve the above object, the present invention provides a central control means for controlling the operation of the whole copying machine, a cassette standard detecting means for detecting the size of a cassette for feeding paper, and detecting the paper sorting mode of the copying machine.

To output Four and a number of sheets greater than the display unit 18.

2 is a flow chart schematically showing the overall performance of the copier according to the present invention.

Now look at the implementation of the present invention.

First, the system is initialized (101), the paper storage mode is set to non-sort mode (NON-SORT) (102), and the number of copies is set to an initial value of 1 (103).

Then, the size of the cassette selected by the user is checked (104), and the classification mode check (105) and the copy number check (106) are sequentially performed. In the present invention, the group mode is performed through the subroutines (104, 105, 106). It is to control not to exceed the standard copy number of the city (see the description of FIGS. 3 to 5 for a detailed process thereof).

After performing the routines 104, 105 and 106, it is checked if the copy start key 14 has been increased (107). When the copy start key 14 is in the OFF state, the routine continues to wait while repeating the routines 104, 105, and 106, and when the copy start key 14 is ON, the copy number check routine 106 is turned on. Turn off (108) and perform copying (109) for the number of excess indicators that may occur at. This means that even if the user sets the number of sheets, the present invention is to command the start of copying after the user confirms this while switching the set number of sheets so that only the proper capacity is automatically stored by the present invention. It means no need.

3 is a flowchart of an exemplary subroutine (see 104 in FIG. 2) for performing a cassette size check according to the present invention.

Looking at the performance process, first determine whether the cassette size is A4 size (SIZE) or less (201), if it is A4 size or less, the cassette standard is A4 (205), or if the cassette size is B4 or less (202) ).

As a result of the check, if it is B4 or less, the cassette standard is set to B4 (203), otherwise, the cassette standard is regarded as A3 standard and set to cassette A3 (204). In this way, when the cassette size is determined, it is returned to the main routine (see FIG. 2).

4 is a flowchart of a subroutine for performing a mode check according to the present invention, which first detects whether a mode key is input (301) and returns to the main routine (see FIG. 2) if there is no input. do.

If there is an input, it is checked whether the input mode is the same as the current mode (302). Thus, if the check result is the same, it returns to the main routine (see FIG. 2). If not, it is again checked whether the input mode is the group mode (303).

If the check result indicates that the input mode is the group mode, the mode to be performed is set to the group mode (305), and returned to the main routine (see FIG. 2). On the other hand, if the result of the check is not the group mode, the corresponding mode such as non-sort mode (NON-SORT) is set (304) and returned to the main routine (see FIG. 2).

5 is a flowchart showing a subroutine for performing a copy number check according to the present invention.

Looking at the execution process, first set the key number input by the numeric key to the number of copies (401). Then it is checked if the set mode is a group mode (402). If not in the group mode, the process returns to the main routine (see FIG. 2). In the group mode, it is checked whether the cassette size is A4 standard (403).

If the cassette size is A4, check whether the number of copies is less than or equal to the maximum number of sheets A4 can be loaded into Sota (404), and if less, return to the main routine (see Fig. 2). If the number of sheets to be set is exceeded, the number of copies is not determined as the number of copies by key input, but is corrected and set to the maximum number of sheets of A4 paper preset (A4 MAX) in advance (405), and the number of copies exceeded (18). ) And return to the main routine (see FIG. 2).

However, if the cassette specification is not A4, it is again checked whether the cassette specification is B4 (406). If the cassette size is B4, check whether the number of copies to be loaded exceeds the maximum number of sheets of B4 (407), and if not, return to the main routine (see Fig. 2), and if so, copy the number of copies to B4 paper. After setting the maximum appropriate number of copies (B4 MAX) (408), the number of excess sheets is turned on (ON) (411) and returned to the main routine (see FIG. 2).

If the cassette specification is not B4, consider the cassette specification as A3 and check whether the number of copies exceeds the maximum number of sheets of A3 paper in Sota (A3 MAX) (409). When exceeding, set the number of copies to be loaded to the A3 maximum appropriate number (A3 MAX) (409), turn the number of copies over on (411), and return to the main routine (see FIG. 2). Returns.

If there are many kinds of copy paper standards used according to the characteristics of the copying machine, the desired purpose can be achieved through a series of procedures for determining the appropriate number of sheets for each copying paper in the same manner as in the above embodiment, and determining this. It is.

As described above, the present invention prevents an operation error by not exceeding the number of copies to be loaded at all times, and sets the maximum appropriate loading amount differently according to the size of paper to be loaded to extend the convenience of use and the service life of the device. Has an effect.
