Abstract

PURPOSE:To facilitate the confirmation of set magnification by displaying the currently set magnification by depressing a magnification setting key on a copying machine which displays copy magnification and a copy quantity on one display part. CONSTITUTION:When the copy magnification setting key of a key input part 101 is pressed while the copy quantity is displayed on a numeric display part 6 which displays both the copy quantity and copy magnification, a microcomputer 200 displays the magnification which is already set on the display part 6 while making an input regarding magnification settings by the depression. Then the display is switched to the copy quantity display a specific time later on condition that the magnification setting key is not pressed. Consequently, numeric display parts need not be provided at two positions and the current copy magnification is easily viewed. Further, the display operation can be commanded without providing any input means which instructs the display the magnification which is already set.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a copying machine, and more particularly to a copying machine having a display section that serves both as a copy number display section and a copy magnification display section.

[Prior Art] Recently, with the aim of simplifying the operation panel of a copying machine, a copying machine has been provided in which a single numerical display unit serves both to display the copy magnification and the number of copies.

For example, when a key switch for selecting a new predetermined copy magnification is input, the copy magnification corresponding to the input switch is displayed on the numerical display section in place of the already displayed number of copies.

[Means for solving the problem] However, in the above-mentioned copying machine, since the display of the number of copies is usually given priority, it is not possible to read the currently selected copy magnification from the numerical display section. Can not.

In particular, any copy magnification can be adjusted with a single key switch.
In a copying machine where the minimum unit of the numerical display section can be freely selected for each input, the magnification displayed as a numerical value itself is a problem, so it is necessary to display the currently set copying magnification as a numerical value. expensive.

The present invention has been devised in view of the above circumstances,
An object of the present invention is to provide a copying machine that can display the currently set copying magnification in a single numerical display unit that displays both the copying magnification and the number of copies.

[Means for Solving the Problems] A copying machine according to the present invention is a copying machine capable of selecting a plurality of copying magnifications, and includes a numerical display means for selectively displaying the number of copies or the copying magnification; determining means for determining whether or not the number of copies is displayed on the display means; input means for inputting a command associated with the copy magnification; and as a result of the determination, the number of copies is displayed on the display means. In this case, when the input means is input, the instruction related to the copy magnification associated with the input is invalidated, and
and control means for instructing the display means to display a current copying magnification that has already been selected.

Here, the numerical display means is not limited to directly displaying the numerical value itself, but may be one that indirectly displays the numerical value.

Further, other information than the number of copies and copy magnification may be displayed.

Further, the input means related to copy magnification refers to, for example, a copy magnification selection key.

[Example] Hereinafter, an example of the present invention will be described with reference to the drawings. The mechanical configuration and copying principle of the copying machine according to this embodiment are well known, so their explanation will be omitted.

FIG. 1 is a plan view of an operation panel 100 of a copying machine according to this embodiment, and FIG. 2 schematically shows an input/output configuration of a microcomputer 200 that controls the copying machine.

As shown in FIG. 1, on the operation panel 100, from the right when facing the front, pressing the print switch 1 and the upper part 401 increases the number of copies, and pressing the lower part 402 decreases the number of copies. A number up/down key 4, a magnification up/down key 5 that increases the copy magnification by pressing the upper part 501 and decreases the copy magnification by pressing the lower part 502, and a numerical value consisting of a 3-digit 7-segment light emitting element. A display section 6, LEDs 71 to 74 for displaying fixed magnification selection, a fixed magnification selection key 8, and other known key switches and display LEDs are provided.

Further, as shown in FIG. 2, a microcomputer 200
is connected to a key switch (key human power unit 101) on the operation panel via an input interface (not shown). In addition, through an output interface (not shown), 3
In order to drive and control the digit numerical display section 6, it is connected to a known drive circuit (not shown). Furthermore, the stepping motor that sets the copying magnification of the copying machine, the exposure scanning motor, etc.
It is connected to a second element driver part 105 that drives and controls other actuators. The microcomputer 200 also includes a CPU 201, a read-only memory ROM 203 that stores a copying machine control program, etc.
It is comprised of a RAM 205 used for writing and reading copy magnification, number of copies, etc., and an input/output section (not shown) that forms part of the input/output interface.

FIG. 3 is a flowchart of a subroutine that is executed by the CPU 201 and shows the main processing of this embodiment. Note that the main routine and other subroutines of the CPU 201 are well known, so they will only be mentioned as necessary.

First, in the initial setting SO, the off flag of the fixed magnification selection key 8 and the off flag of the magnification up/down key 5 are set, and it is determined whether there is an input to the fixed magnification selection key 8 (Sl). When there is no input from the key 8, it is determined whether or not there is an input from the magnification up/down key 5 (S3). If there is no input from the fixed magnification selection key 8 or the magnification up/down key 5, this subroutine is ended and the process returns to the main routine. Above 2
If one of the two keys is input, the multiple display is switched to the current magnification display (S5). In this embodiment, the initial state of the numerical display section is to display the number of sheets, and
If there is no special input of the number of sheets up/down key, select “1”
It is configured to display. Next, timer 1 is started (S7).

Timer 1 defines the time for returning the magnification display to the number of sheets display. Next, it is determined whether timer 1 has expired (S9). If it has not been completed, it is determined whether the fixed magnification selection key 8 has been input (511), and if it has not been input, a fixed magnification selection key off flag is set (813).

Next, it is determined whether the magnification up/down key 5 has been input (515), and if there is no input, the magnification up/down key off flag is set (817), and the process returns to S9. When the key 5 is input, it is determined whether or not the magnification up/down key off flag is set (519).
), if not set, return to S9. On the other hand, if it is set, the magnification is increased or decreased and displayed on the numerical display section 6 according to the key input (823
). That is, when the number of copies is displayed on the numerical display section 6, if you press the magnification up/down key 5 twice, the magnification will change to 1.
times, up or down. Next, when the magnification is increased or decreased (323>, set timer 2 to 8.
25>, it is determined whether the magnification up/down key 5 has been input (827). When key 5 is being input, it is determined whether or not timer 2 has expired (829); if it has, the process returns to 823 and the magnification is increased or decreased. If the timer 2 does not expire, it is further determined whether or not the magnification up/down key 5 has been input (831), and if there is any key input, the process returns to 829. That is, when the input (press) of the magnification up/down key 5 is continued for the time specified by the timer 2, the magnification automatically changes. Also, in 827 or 831,
If there is no key power, the magnification up/down key off flag is set and the process returns to S7 (S33). That is, the timer 1 is newly started.

On the other hand, in S11, when the fixed magnification selection key 5 is input, it is determined whether the fixed magnification selection off flag is set (837).

If the flag is not set, the process advances to 815.

When set, the next magnification is selected and displayed on the numerical display section 6 according to a predetermined rotation (841). Thereafter, in the same way as steps 825 to 831, the timer 2 is set, and if the fixed magnification selection key 8 continues to be input, one after another according to the predetermined rotation at each time specified by the timer 2. Select the next magnification (843-549). Also, 845 or 8
If it is determined in step 49 that there is no input from the fixed magnification selection key 8, a fixed magnification selection key off flag is set (851) and the process returns to step 87.

Furthermore, when the timer 1 ends in S9, the display on the numerical display section 6 changes from the copy magnification to the number of copies, provided that no input is made on the fixed magnification selection key 8 or the magnification up/down key 5. Switch (859). Also, timer 1
After the end, if the fixed magnification selection key 8 is being input when the display on the numerical display section 6 is changed (853), the 8
The process advances to step 41, and if input is being made using the magnification up/down key 5 (S55), the process advances to step S23. In other words, even after switching from the number display to the magnification display, the fixed magnification selection key 8
Alternatively, if it is considered that the input of the magnification up/down keys 5 is continued for the time specified by the timer 1, after the timer 1 ends, a magnification corresponding to the human power of each key is selected.

[Effects of the Invention] According to the present invention, when the input means related to the copy magnification is input while the number of copies is being displayed, the display on the numerical display means is switched to the current copy magnification. Therefore, it is possible to easily visually confirm the current copying magnification without providing two numerical display sections. Furthermore, without providing a new input means for instructing the display of the current copy magnification that has already been selected, it is possible to command the display of the current copy magnification -1o - using input means related to other copy magnifications. Therefore, there is no need to increase the number of key switches on the operation panel, for example.
