Abstract

PURPOSE:To set a copying sheet number exceeding a sheet number which can be displayed on a set sheet number indicator without adding special parts by using a stop key as a many sheet selecting button, too. CONSTITUTION:When a stop key 26 is depressed, an inputted numerical data 23 is multiplied by M and displayed by using both a set sheet number indicator 12 and a copying end sheet number indicator 13. Subsequently, the numerical value multiplied by M is divided by an optional dividing value N, the quotient Q and the remainder R are derived, and also the dividing value N is displayed on the indicator 12. When a print start button 16 is depressed, copying of N sheets is repeated Q times, and when it is completed, the remainder R is displayed on the display part 12. Subsequently, copying is repeated until the remainder R becomes zero. In this way, a copying sheet number exceeding a sheet number which can be displayed on a set sheet number indicator can be set without adding special parts.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a multi-ear plug number control device used for controlling the number of copies of a copying machine.

[Prior art]

Most copying machines equipped with a numeric keypad are designed to manually enter the number of copies to be made for each document (hereinafter referred to as the number of copies), and display this value numerically on the copy number display section.

FIG. 1 shows an example of a display section of a conventional copy number control device. Copy number display section 11
The set number of copies display 12 displays the set number of copies, and the copy end number display 1 displays the number of copies that have been made at the current time.
3. In the figure, continuous copying of 10 sheets has been instructed, and the current copying of 9 sheets has been completed.

Since copying machines rarely make more than 100 copies of a single document in a row, each display is often capable of displaying a two-digit numerical value due to the display space. .

Copying machines installed at copy centers, for example, are often requested to make large quantities of copies for requests such as the production of leaflets. In such a case, conventionally, the number of copies is repeatedly set within a settable range to process a large number of copies. For this reason, (i) the operator is tied to the copying machine for a relatively long period of time, which poses problems in office efficiency. Furthermore, (ii) it is necessary for the operator to plan how many copy operations are to be performed by setting the number of copies, which is not only complicated, but may also lead to operational errors.

For this reason, a copy number control device has been proposed that can manually input a value greater than the value that can be displayed on a set number display as the number of copies.

FIG. 2 shows the main parts of the operation panel in this proposed device. In addition to the above-mentioned copy number display 11, the operation panel 15 also includes a print start point 1.
6 and a multiple selection button 17 are arranged. Assume that the set copy number display 12 of this apparatus is capable of displaying a two-digit numerical value, and that a request is made to make continuous copies of 910 copies.

First, the operator inputs a numerical value 91 using a numeric keypad (not shown), and causes the set number of sheets display 12 to display this numerical value 91. Then, the multiple sheet selection button 17 is pressed. Then, the input numerical value 9 in the tens digit is displayed at the lowest position of the copy end number display 13, and the numerical value 1 in the ones digit is displayed in the tens digit of the set copy number display 12. That is, as shown in FIG. 1, the numerical value 910 is displayed in the four-digit display area including the image displays 12 and 13.

After confirming this value, the operator presses the print start button 16 to start the copying operation.

At this time, it is necessary to display the progress of the copying work on the copy completion number display 13. For this reason, in this proposed copying machine, when copying is started, the preset number of copies display 12 displays a divided two-digit arbitrarily set number of copies as a numerical value, and the number of copies to be completed relative to this number is displayed on the set number of copies display 12. 13.

For example, if the set number of divided sheets is 50, the copying machine repeats the continuous copying operation of 50 sheets 18 times, copies 10 sheets in the 19th copying operation, and copies a total of 91'O sheets. I will finish it. Such work processes are controlled by, for example, a microcomputer or computer.

In this copy number control device proposed by Kokoro, it was necessary to newly arrange a multi-copy selection button 17 on the operation panel or the like. Therefore, even if an attempt was made to add a large-volume copying function like the one mentioned above to an existing copying machine using a microcombi, it would not only be necessary to change the program but also to add new parts, making it difficult to realize. .

[Purpose of the invention]

In view of these circumstances, an object of the present invention is to provide a copy number control device that can set the number of copies that is greater than the number of copies that can be displayed on a set number display without using any special parts. .

[Structure of the invention]

In the present invention, as shown in FIG.
Data storage means 2 for storing numerical data input from
2, the numerical data display drive means 24 for displaying this numerical data 23 on the set number of sheets display 12, and the copy sequence control section 25 for controlling the copy sequence are not performing the original sequence control. When the stop key 26 for stopping the copying sequence is pressed, a mass copy mode setting means 27 sets the number of copies to a value obtained by multiplying the content of the numerical data 23 by M (M is an arbitrary integer); When the copy mode is set, a set copy number display driving means 28 for displaying a value obtained by multiplying the numerical data 23 by M on the copy number display section 11, and a large quantity of copies that are instructed to start copying from the print start button 16. A copy instruction means 31 for instructing mass copying on the condition that the copy mode is set; and a copy instruction means 31 for instructing mass copying on the condition that the copy mode is set; when the copying instruction 33 is output from the copying instruction means 31 and the arithmetic control means 32 which causes the copying to be repeated for N sheets, and thereafter makes copies by the number of copies corresponding to the remainder R of this division. And while copying is being repeated with the set number of N sheets, the division setting data display driving means 34 for displaying the set number of sheets N after division on the set number display 12 and the copying instruction 33 are being output. and a remainder data display driving means 35 for displaying the remainder R of the division on the set number of sheets display 12 after the completion of 47% by the set number of sheets of N sheets; The copy number control device is provided with a copy completion data display driving means 36 for displaying the copy completion number of copies for the set number of copies on the copy completion number display 13.

〔Example〕

The present invention will be described in detail below with reference to Examples.

FIG. 4 shows the copy number control device of this embodiment. A CPU (central processing unit) 41 is connected to an address bus 4.
2 and data bus 43.
It is connected to a memory 44, a read-only memory 45, a numerical data register 46, a set number of copies register 47, a copy end number register 48, and a sequence control circuit 49, respectively. This device is provided with a numeric keypad 51, a stop key 26, and a print start button 16 as input means.
41, and the data is processed through the data node 43. Set number of sheets register 4
7 and the contents of the copy end number register 48 are numerically displayed in the display drive circuits 55 and 56 (thereby, the set number of copies is displayed on the display 12 and the copy end number display W313).

The operation of this device will be explained using FIGS. 4 and 5. Assume that an operator makes 910 copies from one original. In this device, the integer M is set to 10. Therefore, the value 91 obtained by dividing the number 4, 910, by 10 is input from the numeric keypad 51. When the numerical value 91 is input manually (step ■), the CPU 41 registers this numerical data in the numerical data register 46 (step, knob ■). The number "'91" appears on the end number display 13.
” is displayed (step ■).

In this state, the CPU 4' 1 monitors whether or not the strike key 29 is pressed (step 7). While it is not pressed (N), this numerical data will be displayed continuously (this will be displayed. When the stop key 29 is pressed, STEP ■;Y)
, the CPLI 41 determines whether or not the main motor (not shown) is rotating based on the data supplied from the sequence control circuit 49 (step (2)).

The main motor of this copying machine starts its rotation when the print start button 16 is pressed, and rotates when a series of copying sequences is completed or is forcibly terminated by pressing the stop key 29. It is supposed to be stopped. The stop key 29 is thus normally used to forcibly terminate the copying sequence for some reason. Therefore, if the main motor is rotating (step 2; Y), the process shifts to the operation for completing copying (step 2).

On the other hand, if the main motor is stopped (step ■; N
), the CPU 41 reads the numerical data registered in the numerical data register 46, and multiplies the numerical data by M, that is, 10
Double step ■).

Then set the values for the ones place and tens place in the number of sheets register 47
Register it as a 2-digit number. Further, the numerical value in the 100's digit is registered as the numerical value in the first digit of the copy end number register 48. As a result, the numerical value 910 is displayed using both the set copy number display 12 and the copy end copy number display 13 (step 2).

CP'U 41 print start point 1 in this state
It is monitored whether or not 6 is pressed (step ■). When the print start button 16 is pressed (Y), the following operation for mass copying is executed. Until then (
In step (2); N), numerical data is continuously displayed in the mass copy mode.

When the print start button 16 is pressed, the CPU
41 reads the set number N of sheets after division from the read-only memory 45 and registers it in the set number register 47. Also, the contents of the copy end number register 48 are cleared. In this embodiment, if the set number of sheets N is 50, the number 50 is displayed on the set number of sheets display 12 (step O).

Next, the CPU'41 divides the numerical value 910 by the numerical value 50, and obtains the quotient Q and the remainder R (step ■).

The quotient Q is 18° and the remainder R is 10. These values are uniquely stored in random access memory 44.

The quotient Q indicates the number of times the copying operation is repeated with the set number of copies N after division, and the remainder R indicates the set number of copies to be made in the final copying operation performed after this copying operation.

When the calculation is completed, the copying operation starts (step 0
). As a result, a series of copy sequences are executed, and copies are made one sheet at a time (step 0).

Each time copying is completed one by one, the CPU 4 receives an interrupt signal from a sensor (not shown) and detects this.

The number of completed copies determined in this way is sequentially written into the completed number of copies register 48, and its contents are changed. In this way, when the number of completed copies reaches 50, step 0; Y), the random access memory 44
The quotient Q within is subtracted by 1 (step ■). The copying operation continues until the number of copies reaches 50 (step 2; N). While the quotient Q does not become 0 (step [phase]; N), each time the number of copies to be completed reaches 50, the copying operation for the next 50 copies is started.

When the quotient Q becomes 0, step [phase]; Y), the remainder R becomes O
It is determined whether or not it is (Ste Nobu■).

If it is 0 (Y), the copying operation is completed (St. Knob 0
)・. In this case, the remainder R is 10.

In this way, if the remainder R is not O (Ste Nobu @;
N), this numerical value R is written into the set number of sheets register 47. As a result, the numerical value R is displayed on the set number of sheets display 12 (step ■). After this, the copying operation is started. After copying R sheets, that is, 10 sheets, the copying is completed (step knob ■).

〔Effect of the invention〕

As described above, according to the present invention, the stop key is also used as a selection button for mass copying, so the manufacturing cost of the copying machine can be reduced.
