Abstract

PURPOSE:To make a console panel small by providing a display switching means which operate normally plural quantity display means, but operates a magnification display means only when a copy magnification key is operated. CONSTITUTION:A copy quantity is normally displayed on a numeral display part 30, but when a reduction zoom key 25 or enlargement zoom key 26 is operated, data on copy magnifications is sent preferentially to the numeral display part 30 to make a display of the copy magnifications. When the zoom key 25 or 26 is operated, the LEDs of a fixed-magnification display part 31 are all turned off and then a lens motor 3 is driven to move a zoom lens corresponding to the input copy magnifications. After the lens movement, the copy quantity is displayed on the numeral display part 30 instead of the copy magnifications. Consequently, the console panel can be made small.

Description

Detailed Description of the Invention (a) Industrial Application Field The present invention relates to a copying condition input/output device for inputting copying conditions and outputting (displaying) manually-generated copying conditions. This invention relates to improvements in display devices.

(2) Conventional technology In a conventional copying machine, the manual power, set copy magnification, and number of copies are displayed on a display section so that the operator can check the manual power conditions. In this display, conventional copying machines display the copy magnification and the number of copies on dedicated display sections.

(C) Problems to be Solved by the Invention However, the conventional method of providing dedicated display sections for displaying the copying magnification and copying conditions has the disadvantage that display space is wasted.

On the other hand, if the copy magnification and the number of copies are to be displayed on one display, it must be made clear which one is currently being displayed without confusion.

Therefore, an object of the present invention is to eliminate the waste of space caused by displaying the copy magnification and the number of copies separately, and to provide copying conditions that do not confuse the display even when both are displayed on one display section. Its purpose is to provide input/output devices.

(Means for Solving Problem 61) This invention includes a numerical display section capable of displaying numerical values, a copy number key for inputting the number of copies, etc., and a number display for displaying the input number of copies on the numerical display section. means, a copy magnification key for inputting a copy magnification, etc., a magnification display means for displaying the input copy magnification on the numerical display section, the number display means being operated during normal times, and the copy magnification key being operated. The present invention is characterized by comprising display switching means that operates the magnification display means only when the magnification display means is turned on.

(81 Effect) In this invention, both the copy magnification and the number of copies are displayed on the numerical display section. Normally, the number of copies is displayed on the numerical display section, but only when the copy magnification key is operated. The copy magnification will be displayed. In this way, when the copy magnification is displayed, the times when the number of copies is displayed are determined, so there is no confusion as to which one is being displayed.

(f) Embodiment FIG. 2 is a block diagram of the main parts of a copying machine which is an embodiment of the present invention.

The entire copying machine is controlled by a controller l.

The controller 1 is connected to input keys 21 to 29 and a display section 30.31 provided on the operation panel 2 on the top surface of the copying machine main body, as well as a motor 3 for moving the zoom lens of the optical system and other processes related to the copying process. Device is connected. The controller 1 is provided with an area for storing copy conditions such as the number of copies and copy magnification, and stores copy conditions input by key operations.

The human keys on the operation panel 2 include a print switch 21, numeric keypad 22, clear key 23, magnification call key 24, reduction zoom key 25, enlargement zoom key 26, fixed magnification key 27, density mode switching key 28, and density setting knob. 29 are provided. Further, as a display section, a numerical value display section 30 and a fixed magnification display section 31 are provided.

Here, each person's role will be explained. The print switch 21 is a key for starting the copying process, and the numeric keypad 22
is a key for inputting the number of copies, and the clear key 23 is a key for canceling numerical values input using the numeric keypad. The magnification call key 24 is a key for displaying the copy magnification on the numerical display section 30, and the reduction zoom key 25 and the enlargement zoom key 26 are keys for changing the copy magnification in the direction of reducing or enlarging by 1%. In addition, the fixed magnification key 27
is a key for selecting a copying magnification that is fixed in advance.For example, pressing the key when copying at the same size, copying from a specified size to another specified size (copying from A4 to B5, etc.) You can easily select those magnifications by just clicking the button. Note that the reduction zoom key 25. When the enlargement zoom key 26 and the fixed magnification key 27 are operated, the controller 1 drives the lens motor 3 to move the zoom lens so that copying can be performed at the set copying magnification.

The density mode switching key 28 is a key for switching between automatic density setting mode and manual density setting mode. In the automatic density setting mode, the density of the original is detected by a density sensor, and the density of the copied image is set accordingly. However, in the manual density setting mode, a light image or a dark image is formed according to the user's wishes. The density setting knob 29 is a key for setting the image density in the manual density setting mode.

Further, the copy magnification or the number of copies is displayed on the numerical display section 30, and the fixed magnification selected by the fixed magnification key 27 is displayed on the fixed magnification display section 31. Note that the fixed magnification display section 31 is a simple device with LEDs arranged corresponding to each fixed magnification, and requires less space than the display section provided in conventional copying machines that numerically displays the copy magnification. should be quite small.

The processing procedure for controlling the display on the numerical display section 30 in such a copying machine is shown in flowcharts in 1I and 2I.

In the normal state, the number of copies is displayed on the numerical display section 30. When the key of operation pulse 2F is turned on (n
l) The type of the key is determined (n2.n8.n12
...). For example, in the case of the reduction zoom key 25 or the enlargement zoom key 26, the copy magnification is changed by reducing or enlarging it in 1% increments, and the set copy magnification is stored in the storage area of the controller l. The magnification is then displayed on the numerical display section 30 (n2→n3→n4). As mentioned above, the number of copies is normally displayed on the numerical display section 30, but the reduction zoom key 25 or the enlargement zoom key 2
By the operation 6, the copy magnification data is sent to the numerical display section 30 with priority, and the copy magnification is displayed. Note that when the zoom keys 25 and 26 are operated, all the LEDs of the fixed magnification display section 31 are turned off. Then, the lens motor 3 is driven, and the zoom lens is moved in accordance with the input copying magnification (n5→n6).

When this lens movement is completed, the number of copies will be displayed on the numerical display section 30 (n' 7) instead of the copy magnification 'Efr L'.On the other hand, if the fixed magnification key 27 is operated (the fixed magnification The LEDs of the fixed magnification display section 31 are switched accordingly.
3). Then, the zoom lens is moved according to the set copying magnification (n14→n15). At this time, the number of copies remains displayed on the numerical display section 31.

As mentioned above, the number of copies is normally displayed on the numerical display, but when the magnification call key 24 is operated, the copy magnification is displayed instead of the number of copies (n8→n
9). This copy magnification is displayed using the copy magnification call key 24.
This is only while the key is being pressed, and when the key is no longer pressed, the display is switched to the number of copies (n10→n11).

In this embodiment, the "copy magnification keys for inputting copy magnification, etc." are the reduction/enlargement zoom key 2526 and the magnification call key 24.

In this embodiment, the number of copies is kept displayed on the numerical display section when a fixed magnification is displayed, but the numerical display section 30 may be used to display the magnification even when a fixed magnification is displayed. In this case, the fixed magnification display section 31 may be abolished. Also, when displaying the copy magnification on the numerical display section 30 by operating the magnification call key 24, the magnification call key 24
Although the copy magnification is displayed only while the key is pressed, the copy magnification may be displayed for a certain period of time (about several seconds) by pressing the key.

(g) Effects of the Invention According to the present invention, since the copy magnification and the number of copies are displayed on one numerical display section, one display section can be eliminated and the operation panel can be made smaller. In addition, the number of copies is displayed in the numerical display section under normal conditions, and the copy magnification is displayed only when the copy magnification key is operated, so it is determined whether the number of copies or the copy magnification is the same. It is possible to prevent display confusion without confusing what is being displayed.
