JPS62297863A - Display device for the number of copying sheets - Google Patents

Abstract

PURPOSE:To accurately recognize the total number of copies even if additional copying is executed by depressing a print key by additionally displaying the added number of copies by interruption on a total number display part and a subtraction display part. CONSTITUTION:The set number of continuous copies and the residual number of copies obtained at every copying are displayed by the operation of a microcomputer. The number of copying sheets to be added is processed based on an interruption processing routine. When the interruption of additional copying is generated during the operation of a copying machine in a normal routine having no additional copying and the print key 4 on the copying machine is depressed, the additional number of copying sheets is added to the total number of copying sheets and the residual number of copying sheets and the added values are displayed. Even in a copying machine reduced at its cost by reducing the number of keys, the total number of copying sheets can be always recognized by the additional copying on the way of copying.

Description

Detailed Description of the Invention 3. Detailed Description of the Invention (Field of Industrial Application) The present invention relates to a copy number display device in a copying machine.

(Prior Art) Conventionally, when making copies of one document in a general copying machine, the number of copies is entered from a numeric keypad, and the number of copies is displayed on a copy number display section. In addition, the number of remaining copies is displayed by subtracting one each time one copy is made.

Also, Japanese Patent Application Publication No. 61-2163 and Japanese Patent Publication No. 61-146
Japanese Patent No. 47 proposes a copy number display device that is configured to omit the numeric keypad and set the number of copies by the number of presses of the print key.

(Problem to be Solved by the Invention) However, since the above-mentioned copy number display device is configured to subtract and display the number of copies, if the number of copies is added by an interrupt during continuous copying, etc. teeth,
There was an inconvenience that the total number of copies was unknown.Especially in the case where the number of copies is set by the number of times the print key is pressed, the number of copies is added by an interrupt, regardless of the initial setting. In this case, it is often difficult to know the number of additional sheets and the total number of sheets, which causes inconvenience during use.

The present invention aims to solve the above-mentioned conventional problems.

(Means for Solving the Problems) In order to achieve the above object, the present invention includes a subtraction display section that displays the set number of consecutive copies and also subtracts 1 each time one copy is made to display the remaining number of copies. and a total number display section that displays the total number of copies to be continuously copied, and is configured to add the number of copies added by interruption to the number of copies displayed on the subtraction display section and the total number display section and display the result. It is something.

(Function) Since the present invention has the above configuration, it is possible to display the total number of copies as well as the remaining number of copies to be made, so that it is possible to display how many copies remain to be made and the total number of copies. This can be easily confirmed by looking at the display device. Therefore, especially when adding the number of copies by interrupt,
Since you can immediately know how many copies will be made in the end, you can set and add the number of copies by pressing the print key - Eliminate the situation where you lose track of the total number of copies even in cases be able to.

(Example) Hereinafter, an example of the present invention will be described with reference to FIGS. 1 to 3.

In FIG. 1, reference numeral 1 designates a part of the operation panel placed at a suitable location on the top surface of the copying machine, which includes a subtraction display section 2 that displays the remaining number of copies to be made, and a subtraction display section that displays the total number of copies. 2, a total number display section 3 for displaying the total number of copies, a print key 4, and a clear key 5 for setting the number of copies to 0. The operation signals of the print key 4 and clear key 5 are input to a microcomputer (not shown) that controls all operations of the copying machine, and the subtraction display section 2 and total number display section 4 are controlled by the signals from this microcomputer. configured to be activated.

Next, the operation of displaying the number of copies will be explained in relation to the copying operation based on the flowcharts of FIGS. 2 and 3. When the copying machine is turned on and starts operating, the numerical value N corresponding to the subtraction display section 2 is set to O, and the numerical value M corresponding to the total number display section 3 is also set to O according to the flowchart in FIG. (Steps #1 and #2), and regardless of this numerical value NSM, the subtraction display section 2 and total number display section 3 display 1.
(Steps #3 and #4). Next, it is determined whether N is 0 (step #5), and if it is 0, step #5 is repeated to enter a standby state.

If it is not 0, the process advances to the next step #6 and a copying operation is performed. If the print key 4 or clear key 5 is operated during this time, an interrupt process is performed based on the interrupt process routine shown in FIG. 3 as an interrupt operation.

In this interrupt handling routine, it is first determined whether the clear key 5 has been pressed (step 7'#11), and if the clear key 5 has not been pressed, it is further determined whether the print key 4 has been pressed. (Step #
12) Determine whether there is an interrupt operation. If neither the clear key 5 nor the print key 4 is pressed, the process returns as is. If the clear key 5 has been pressed, the NSM is set to O, the subtraction display and the total number display are set to 1, and the process returns (steps #13 to #16).

If the print key 4 is pressed, add 1 to the numbers N and M (step #17 #1B),
After displaying the numbers N and M on the subtraction display section 2 and the total number display section 3, respectively, return is made (steps #19 and #20).
. If the print key 4 is further pressed and an interrupt occurs, the operations from steps #17 to #20 are repeated, and the numerical values N, M and the number of displayed values increase.

Corresponding to these interrupt processes, after the copying operation in step #6 of the flowchart of FIG. 2, it is determined in step #7 whether N is O. This is to check whether N has been set to 0 by the interrupt operation of the clear key 5, and if it is 0, step #5 is repeated and the system enters a standby state. On the other hand, if N is not 0, the process moves to step #8 and the value on the subtraction display section 2 is changed to N.
If there is an interrupt operation using the print key 4, the remaining number of copies added by the number of interrupt operation ports is displayed.

Next, after N is set to N-1 by subtracting the copying operation completed bone (step #9), it is determined whether N is O (step #10). If N is 0, it is assumed that the required number of copies have been completed and the process returns to step #2, M is also set to 0, the subtraction display and total number display are set to 1, and step #5 is repeated to enter the standby state. . If N is not O, the process returns to step #6, and steps #6 to #10 are cycled until N becomes 0, during which time the copying operation is continuously repeated. If there is an interrupt during this continuous copying, the routine moves to the interrupt routine as described above and is cleared or N and M are incremented.

The present invention is not limited to the above embodiments. For example, instead of setting the number of consecutive copies based on the number of times the print key is pressed, the number of copies may be set in proportion to the time the print key is pressed. For example, the number of copies may be counted while the print key is pressed. Further, the present invention is not limited to a machine in which the number of copies to be copied or the number of additional copies is set using a print key, but can also be applied to a machine in which the number of copies is set using a numeric keypad or the like, and a convenient copying machine can be obtained.

(Effects of the Invention) According to the copy number display device of the present invention, it is possible to display the total number of copies as well as the remaining number of copies to be made. You can easily check whether there is one by looking at the display device. Also, when adding the number of copies by interrupt,
You can immediately know how many copies you will end up making. Therefore, the number of copies can be set and added by pressing the print key, so that even in a copying machine that has fewer keys and aims to reduce costs, it is possible to prevent the total number of copies from becoming unknown. It has the effect of being able to
