Abstract

PURPOSE:To set a quantity consisting of >=three digits on a two-digit display device by inputting a two-digit numeric value as a 1st and a 2nd display with ten keys and calculating the sum of the numeric value which is 100 times as large as the numeric value of the 1st display and the numeric value of the 2nd display. CONSTITUTION:A sheet quantity setter is provided with a microcomputer and a quantity is registered with the ten keys. At this time, the quantity is set on the two-digit display device with the ten keys as shown in figures (a)-(f). A decimal-point display 2d is turned on first as shown in the figure (a). Then numerals (e.g. 4 and 3) are inputted to 2nd and 1st number display devices 2b and 2a as shown in the figure (b)-(c) to obtain the 1st display. Then a decimal-point display 2c is turned on as shown in the figure (d). Similarly, numerals (e.g. 2 and 1) are inputted as shown in the figures (e)-(f) to obtain the 2nd display. Then the sum (e.g. 2 and 1) of the numeric value which is 100 times as large as the numeral of the 1st display and the numeric value of the 2nd display is set in the quantity register. Thus, a numeric value consisting of >=three digits can be set on the two-digit display device while the quantity is confirmed on the display.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a method for setting the number of sheets in an image forming apparatus, and more specifically, in an image forming apparatus having only a two-digit decimal sheet number display, This invention relates to a number setting method for setting the number of sheets of digits or more.

[Conventional technology]

There are PPC and printers as conventional image forming devices.
Most of the number indicators in these devices are 2-digit decimal indicators.

Therefore, since numbers above the hundredth place cannot be confirmed on the display,
The number of copies and prints is set to 99 or less in the first grade.

[Problem that the invention seeks to solve]

The conventional PPCs and printers mentioned above have the ability to continuously copy or print hundreds or tens of sheets, but the number of copies and prints can only be set up to 99 sheets. It is not possible to copy or print hundreds or tens of sheets, and it is necessary to copy or print several times, resulting in a complicated operation.

Therefore, an object of the present invention is to use a decimal 3-digit display in an image forming apparatus that has only a 2-digit decimal display.
To provide a number-of-sheets setting method capable of setting a number of sheets of digits or more while checking the number on a display.

[Means for solving problems]

The sheet number setting method of the image forming apparatus of the present invention includes a 7-segment number display with a 2-digit decimal point for displaying the sheet number and a numeric keypad for inputting the sheet number! In an image forming apparatus, at least two states, a first display state and a second display state, are distinguished and displayed by turning on and off the decimal point display, and two decimal digits or two decimal digits input from the numeric keypad in the first display state are displayed. A 1-digit number is displayed on the 7-segment numeric display, and the number is multiplied by 100. In the second display state, a 2-digit decimal number input from the numeric keypad is displayed on the 7-segment numeric display, and the number is multiplied by 100. A feature of the configuration is that the sum of the above multiplied value by 100 is set in the number of sheets register, thereby making it possible to set the number of sheets with a value of three or more decimal digits.

[Effect]

A 7-segment numeric display is used as the numeric display for displaying the number of sheets. Such a 7-segment numeric display is generally provided with a decimal point display, but this decimal point display has not been used in conventional sheet count displays.

However, if this decimal point display section is used, at least two display states can be distinguished and displayed independently of the numeric display by turning it on and off.

Therefore, if one of the two display states is made to correspond to the display of the hundreds (and thousands) place, and the other is made to correspond to the display of the - place and the tens place, a two-digit decimal display can be used. Even if there is, it is possible to substantially display three digits (or more).

Therefore, according to the method of the present invention, even if the display only has a 2-digit decimal number display, the decimal point display can be used to confirm and set the number of 3-digit or more decimal digits on the display. You will be able to do this.
