Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a copier number display device.

<Prior Art> The number display device of a copying machine is two
A two-digit numerical value can be digitally displayed on the segment display. This is 1
This corresponds to the fact that many copies are made from one to several tens.

On the other hand, paper cassettes installed in copiers
About 00 copy sheets can be stored. Although the frequency of use is not high, a large number of copies of 100 or more sheets may be required. For example, hundreds of leaflets for distribution may be made by copying instead of printing.

In view of such circumstances, a copier capable of displaying three digits is desired even in popular models. However, increasing the number of seven-segment displays leads to an increase in the size of the operation panel and an increase in the price of the copier. Not preferred.

Therefore, as a technique already proposed, a dot display element provided in a 7-segment display is used as disclosed in, for example, JP-A-58-171084 and JP-A-63-80555. There is a number display device for displaying the number of the upper digit.

<Problem to be Solved by the Invention> The prior art proposed in the above-mentioned publication has a drawback that it is difficult for a user to know how many numerical values are displayed on the dot display element. Further, since only one or two dot display elements are used, the numerical values that can be displayed are limited to only “1” or “1” and “2”.

Therefore, for example, in the case of a device capable of digitally displaying a two-digit numerical value, a maximum of "29"
Only 9 "can be displayed, and more than 300 images cannot be displayed.

As described above, in the conventional device, there is a drawback that an appropriate display that is easy for the user to understand cannot be performed, and the number that can be displayed is limited.

SUMMARY OF THE INVENTION The present invention has been made in view of such a background, and an object of the present invention is to provide a copier number display apparatus capable of displaying a practically necessary and sufficient number of sheets without increasing the number of displays or display elements. And

<Means for Solving the Problems> The present invention relates to numerical data display means for digitally displaying numerical data of a predetermined number of digits, and contents relating to a predetermined copy process such as copy density or copy paper size. A copy content display means which is displayed by selectively lighting one of a plurality of display elements arranged in a line, wherein the plurality of display elements of the copy content display means When a number display in which one-digit integers are sequentially assigned and numerical data having one digit larger than the number of digits that can be displayed by the numerical data display means are given,
Display control means for performing numerical display of the most significant digit or the least significant digit by selectively blinking any of the plurality of display elements indicated by the number. A display device.

<Operation> When a numerical value which is one digit larger than the number of digits that can be displayed by the numerical data display means is given, one of the plurality of display elements of the copy content display means blinks at the most significant digit or the least significant digit. It is displayed by being done. Since a number is displayed on a plurality of display elements, the number of blinking displays can be determined at a glance.

An embodiment of the present invention will be described below with reference to the drawings.

FIG. 2 is a plan view showing a specific example of the operation panel 10 of the copying machine according to one embodiment of the present invention.

The operation panel 10 is provided with a copy number display section 11 for displaying the set copy number or the copy execution number.
The number display section 11 includes a first seven-segment display 12 for displaying the first digit and a second seven-segment display 13 for displaying the tenth digit. The first 7-segment display 12 has a first dot display element 14 at the lower right position.
Similarly, a second dot display element 15 is provided at a lower right position of the second seven-segment display 13.

The operation panel 10 is also provided with a numeric keypad 16, and when the numeric keypad 16 is pressed, a set number of copies can be input.

The operation panel 10 is further provided with seven display elements 171, 172,..., 177 for displaying the copy density.
Each of the seven display elements 171 to 177 has a number displayed at an upper portion thereof, and “1” is sequentially displayed from the left end to the right end.
"2" ... "7" are displayed. Seven display elements 171
177 indicate that the display element having a lower number has a lower copy density and the display element having a higher number has a higher copy density. The copy density is automatically set when the automatic exposure switch 18 is turned on, or is manually set by adjusting with the copy density adjustment key 19, and according to the set density, any one of the display elements 171 to 177 is set. Is selectively lit. The feature of this embodiment is that, as will be described later, the display density can be displayed by these display elements 171 to 177 and the number of copies can be displayed.

The operation panel 10 also includes five toner color display elements 201, 202,..., 205 for displaying the toner color, a toner color selection key 21, a zoom key 22 for changing the magnification, and an equal size designation key 23, and any paper cassette. , 248, a paper cassette switching key 25, a sorter mode switching key 26, a copy magnification display unit 27, a monitor unit 28, a print key 29, and the like.

FIG. 3 is a block diagram of the display control circuit of this embodiment. The display controller 30 is provided with the number data and the copy density data. The copy number data is a set copy number given from the numeric keypad 16 or a copy execution number given with the copy operation. The display control unit 30 determines the first seven-segment display 12, the second seven-segment display 13, and the display element 17 based on the given data.
The display control of 1 to 177 is performed.

FIG. 1 is a flowchart showing the operation of the display control unit 30 in FIG.

Next, the operation of the number display device according to this embodiment will be described with reference to FIGS.

When the power supply is turned on and the control operation starts, the display control unit 30 determines whether or not density data has been given (step S10).
1) If density data is given, 7 display elements 1
Selectively light any of 71 to 177 (step S
2). Therefore, the user can confirm the copy density based on which display element is turned on. In addition,
If the density data is not given, the set automatic exposure state is set when the power is turned on, and the copy density is automatically set according to the document density.

Next, the display controller 30 determines whether or not the number data has been given (step S3). Now, for example, a case where “345” is given as the number data will be described. When the number data "345" is given, the numerical value of the first digit of the given number data, in this case "5", is determined, and the number "5" is displayed on the first seven-segment display. 12 is displayed (step S4). If it is determined in step S3 that the number data is not provided, the display control unit 30 displays “1” on the first seven-segment display 12 (step S5). The display control unit 30 determines whether or not the given number data has two digits or more. In this case, since it is two or more digits, of the given number data,
The tenth digit "4" is displayed on the second seven-segment display 13 (step S7).

If the given number data is not two digits or more, the display control unit 30 sets the second seven-segment display 13 to a blank state in which the second seven-segment display 13 is not turned on at all (step S8).

Further, the display control unit 30 determines that the given number data is 3
It is determined whether it is a digit or not (step S9). In this case, since the number is three digits, the number “3” at the 100th place is determined, and the display element 173 assigned with a number corresponding to the number “3” is assigned. Blinks (step S10).

In the case where any of the display elements 171 to 177 blinks, if the element is the same as the element lit and displayed in step S2, the process in step S10 has priority, and the display element changes from lighting to blinking. . Therefore, depending on the blinking display element, the copy density and the number of copies
You can see the 0th digit.

In the above embodiment, the display element 171 for displaying the copy density is used.
By using ~ 177, the 100th digit of the number data is set to "1" ~
Although up to “7” can be displayed, the numerical values of the “100” digit “8” and “9” may be displayed by the dot display elements 15 and 14. In other words, the second dot display section 15 may be turned on and off if the numerical value of the 100th digit is “8”, and the first dot display section 14 may be turned on and off if it is “9”.

Since the copy density display elements 171 to 177 are numbered, these elements are used. However, the other display elements, for example, the toner color display elements 201 to 205 and the cassette display elements 241 to 248 are respectively numbered. However, they may also be used for numerical display of the 100th digit of the number of copies.

Furthermore, if the display elements 171 to 177 are arranged on the upper digit side of the number display section 11, that is, immediately to the left of the number display section 11, the 100th digit of the number data is displayed by the display elements 171 to 177. When read, it has the advantage of being easy to read.

In the above embodiment, the upper digit data which cannot be displayed on the 7-segment displays 12 and 13 is displayed on the display elements 171 to 177. However, when the 3-digit data is given, the upper 2 digits are displayed. The 7-segment displays 12 and 13 are displayed, and the least significant digits are displayed on display elements 171 to 177 and dot display elements 15 and 14.
May be displayed.

<Effect of the Invention> Since the present invention is configured as described above, it is possible to provide a copier number display device capable of displaying one digit more number data without increasing the number of displays. In addition, the displayed number can be displayed in a manner that is easy for the user to see.
