Abstract

PURPOSE:To reduce the number of keys and to simplify arrangement by using an all-reset key also as a stop key, using a key for two purposes as the stop key when the copying action is performed and using it as the all-reset key when the copying action is not performed. CONSTITUTION:In the control panel 100, an all-reset/stop key 91 serves as the all-reset key releasing all kinds of specification and returning an initial state when the copying action is not performed and serves as the stop key stopping the copying action when the copying action is performed. The action timing of the stop key and that of the all-reset key are different, whereby the stop key can be also used as the all-reset key. The all-reset key releasing copying conditions is also used as the stop key in consideration of a following case which may occur sometimes: when the setting of the various kinds of copying conditions is mistakenly performed and when a start key is pressed, a user would like to stop the copying action and release the copying conditions. Thus, the number of the keys can be reduced and the arrangement can be simplified.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to an operation panel for inputting operations such as setting the number of copies, stopping, and other operations of a copying machine.

(Prior art and its problems) Conventionally, the operation panel of a copying machine has a numeric keypad for setting the number of copies, a display means for displaying the number of copies, a start key for instructing to start copying, and a stop key for instructing to stop copying. keys, an all-reset key that cancels various settings and returns to the initial state, and the like are provided independently.

However, in an operation panel with this type of configuration, each key has an independent function, so it is necessary to arrange as many keys as necessary (at least as many as the required functions), which inevitably results in a cluttered appearance. , which also hinders cost reduction.

SUMMARY OF THE INVENTION An object of the present invention is to provide an operation panel for a copying machine that has a simplified arrangement by reducing the number of keys.

(Means for Solving the Problems) Therefore, the operation panel of the copying machine according to the present invention includes a copy data input key for inputting a copy mode data including at least the number of copies, and a memory for storing data input by the copy data input key. a storage means for displaying copy data stored in the storage means; a print key for instructing a copying machine to start a copying operation;
All reset to clear the copy mode data stored in the storage means and return it to the initial value! - Determine whether the key is copying or non-copying, and when copying,
- A control means for using the all reset key as a stop key for stopping the copying operation of the copying machine.

(Function) According to the above configuration, the user's psychology when it is necessary to stop the copying operation when the start key is pressed due to setting various copying conditions by mistake, which often happens, can be adjusted. , (stopping the copying operation) is equivalent to (desiring to cancel the copying conditions), one key is used as both the all reset key and the stop key, which cancels the copying conditions. It does not work at the same time as the key.

(Example) The present invention will now be described in detail with reference to the accompanying drawings.

(a) Operation pile FIG. 1 shows the appearance of an operation panel 100 according to an embodiment of the present invention. In the copying machine of this embodiment, it is possible to set the binding margin mode, border erase mode, and book division copy mode, and the all reset key returns these modes to their initial settings. Note that settings such as magnification and paper size are also normally performed, and their explanation will be omitted in this embodiment.

70 is the copy number display area, key 75 is the print start key, rOJ to "9" keys on the numeric keypad for inputting the number of copies, key 90 is the clear key, key 91 is the all reset key and stop key, and key 93 is the binding margin specification. /Release key, 9 3

The all-reset key (AR)/stop (S) key 91 functions as an all-reset key that cancels all various specifications and returns to the initial state when copying is not in progress, and stops the copying operation while copying is in progress. Acts as a stop key. Since the operation timings of stop and all reset, 1. are different, they can be used together.

In particular, when a user uses a copying machine, the all-reset key is used frequently because it is easy to return the copying machine to the Vj period state by pressing just one key. Furthermore, the star I key is of course used frequently, and these frequently used keys are often arranged side by side in positions that are easy to operate.

Furthermore, it is desirable that the stop key, which is used in an emergency, be located in a position that is easy to operate.

(b) Structure of Copying Machine FIG. 2 shows a schematic sectional view of an electrophotographic copying machine using an operation panel according to the present invention.

The copying mechanism of this electrophotographic copying machine main body 1 is similar to that of a conventional electrophotographic copying machine. In the center of the copying machine body 1,
A photoreceptor drum 2 that can be rotated counterclockwise is provided, and around the photoreceptor drum 2 there are a main eraser lamp 3, a main charger 4, a developing device 7, a transfer charger 8, and a transfer paper separation device. A charger 9, a blade type cleaner device 10, and the like are sequentially provided. The photoreceptor drum 2 is a drum with a photoreceptor (for example, selenium) provided on its surface, and upon each copy, it is irradiated with light by an eraser lamp 3, charged by passing through a charger 4, and then An image is exposed from the optical system to be described. The motor M1 drives the photosensitive drum 2 and the like.

The optical system is installed below the document table glass 11 so that the document image can be scanned. The optical system includes a light source 12, a first mirror 13, a second mirror 14, a third mirror 15, and a projection lens 1.
6 and a fourth mirror 17. The original image is line 1
8 each mirror +3.1.4,15.17 as shown
After that, it reaches the photoreceptor Drano-2. Fixed position switch 5
W50 is provided to detect whether the optical system is at a predetermined position during scanning. Also, switch 5w51
is provided to generate a timing signal for rotating the timing roller 2G. The magnification is set by moving the projection lens 16 in the optical axis direction with a motor M4.

Note that the motor M3 drives the optical system. When the copying magnification is n, the light source j2 and the first mirror 13 are rotated by the C1 motor M3 at (v/n ), and at the same time, the second mirror 14 and the third mirror 1
5 means moving to the left at a speed of (v/211). Along with this movement, the image is exposed from the fourth mirror 17 onto the photoreceptor tram 2 in the form of a slit.

On the left side of the copying machine main body 1, there is a "single moving paper feed cassette 20.2".
1 or 2, respectively, are installed in the second paper slot and the bottom paper feed slot.

The paper in the automatic paper feed cassette 20, 21 is selectively fed into the copying machine main body 1 by the first paper feed roller 22 and second paper feed roller 23, which are the respective paper feed rollers. It passes through the pairs 24 and 25 and is conveyed to the timing roller 26 which is in a pressed state, where it is temporarily on standby.

During transfer, the paper fed by the timing roller 26 comes into close contact with the photoreceptor drum 2 in the transfer section, and the toner image is transferred by the corona discharge of the transfer charger 8, and then the toner image is transferred by the corona discharge of the separation charger 9 and the transfer paper. It is separated from the photoreceptor drum 2 by its own strength. Next, the paper is suctioned onto the general conveyance belt 27 by means of an air suction means (not shown).
It is conveyed to the right according to the clockwise rotation of 7.

Next, by passing through a fixing device 28, the first image is melted and fixed. Then, it passes through a pair of discharge rollers 29 and is discharged to a tray 30 outside the copying machine main body 1 or to a stacker or sorter (not shown).

One type of paper switch 401, 402 and 403゜404
are microsinches that detect the type of paper in cassettes 1-20 and 21, respectively.

Paper size detection switch 410~413.414~
417 is a micro switch installed in parallel to the lower paper feed slot, which allows you to check the size of the paper in the paper feeder 1-20.21 and whether it is installed vertically or horizontally with respect to the paper feed direction. Detect. In addition, switches 420, 42
] also detects the attachment and detachment of cassettes 1-20 and 21.

(c) Control section of the copying machine FIG. 3 shows a control circuit for the operation panel 100 and the copying machine main body 1 according to the present invention.

The CPUI (201) controls the copying machine main body 1. As shown in the figure, the input terminals of the CPUI (201) are connected to the main motor M1, the developing motor, a clutch for operating the timing roller 26, a clutch for operating the second paper feed roller 22, a clutch for operating the lower paper feed roller 23, and charging. Signal terminals and keys from charger 4 and transfer charger 8 (75,
The switch matrix 204 such as 80-91, 93°94.95) is connected. The output terminal includes a decoder 207"f6, a two-digit number display section 70, and an LED 93a that does not indicate various settings.
93b, 93c, 94a, 94b, 94c, and 95a are connected. Also, the CPU 2 (2
02).

CPU2 (202) is for controlling the optical system. A scan motor control circuit 205 that controls a scan motor M3 and a variable magnification lens control circuit 206 that controls a motor M4 that moves the projection lens 16 are connected to the human output boat of the CPU 2 (202). In addition, signals from the optical system position value switch 5W50 and the timing signal generating switch SW5 are input manually.

(d) Control flow The control flow of the CPU (201) that controls the copying machine main body 1 will be explained below.

d-1 Main Routine In FIG. 4, the main motor of cpuI (20) is not shown. cpul (201) is reset and Progera l
When \ starts, the CPU I (201) is initialized, such as clearing the RAM and setting various registers, and initial settings are made to put the device into the initial mode (steps from step S11 onwards are omitted).

Next, an internal timer built in the CPUI (201) and whose value has been set in advance in the initial setting of Sl is started (S2). Then, the following subroutine processing: panel control (S3), copy operation (S4)
are called sequentially.

When all subroutine processing is completed, the first set internal timer is waited for to end (S5), one routine is ended, and the process returns to S2. This length of time for one routine is used to count the various timers that appear in the subroutine. (The various timer values determine when the timer ends based on how many times this one routine is counted.)
d-2 Initial Routine FIG. 5 shows an initial routine that is the initial setting of 81 in the main routine (FIG. 4). In this initial routine, initial processing such as setting various registers of the CPU and setting of various flags are performed.

First, reset the copy start flag to O, which indicates that copying has started, 1-L (Sll), and then reset the copying flag, which indicates that copying is in progress, to O.
(S12), number of copies (in this embodiment, the example shows a case of 2 digits, that is, the maximum value is 99), set the first flag used in manual operation to 1, Sera l-L(S), 3 ),
The 10th flag is reset to O (S14). Also,
Set the stop flag to O to indicate that the copy operation is to be stopped.
(S15).

d-3, Panel Control The 33 panel function 1-roll routines in the main routine in Figure 6 (a), (b), (c), and (d) will be explained separately for non-copy operation and copy operation. .

This panel control routine
The ON10FF determination of the stop key is always made regardless of whether a copy is being performed or not.

II- ■Panel control during non-copy operation When in non-copy operation (copying flag - ○), turn on the clear key 90.
Then (S22), the copy counter is set to 1 (S23), 1
1st place flag to 1 (S24), 10th place flag to 0 (S25)
Set each.

And "1" to "9" keys 81 to 8 of the numeric keypad
9 is turned ON (S26), and if the 1st flag is 1 (S27), it is assumed that this is the first numeric keystroke, and the value is stored in the copy counter (528), and the 1st flag is set to O (S29). ), set the 10th place flag to 1 (S 30)
set. Also, if the numeric keypad is manually powered or the 1st flag is O and the 10th flag is 1 (S31), it is considered to be the second numeric keystroke, and the copy stored when the 1st keypad was manually powered. The value in the counter is multiplied by 10 and the value input for the second time is added, and the value is newly stored in the copy counter. Then, the 10th place flag is set to 0 (S33), and since both the 1st place and 10th place flags become O, it is determined that a two-digit numerical value has been input.

Next, the "0" key 80 is turned on (S36), and if the 1st flag indicating the first numeric keypad manual effort is 1 (S37), this 0 manual effort is meaningless, so ignore it. The process moves to S41. If the 1st place flag is 0 and the 10th place flag is 1 (338), the input of the key 80 is treated as the second input, and the first manual value is multiplied by 10 and stored in the copy counter (539). Since the 2-digit person J has been completed, 10
The position flag is set to 0 (S40) and the process moves to S41.

Next, in S41, it is determined whether the binding margin key 93 is ON. If it is ON and L E D 93 a is ON (S42), turn off the LED 93a and turn off the LED 93b to cancel the currently set 5mm margin.
N, set the binding margin to 10mm (S43), and S4
Proceed to step 9. If LED931) is ON (S44),
L to cancel the currently set binding margin IQmm.
Turn off the ED93b, turn on the LED93c, set the binding margin to 15 mm (S45), and proceed to 849. L
If the ED93c is ON (S46), turn the LED93c ON to cancel the currently set binding margin of 15mm.
F F and release the binding margin mode itself (S47)
, proceed to S49. If the LEDs 93a, 93b, and 93c are all OFF, immediately, if the binding margin mode is canceled, the LED 93a is turned ON, the binding margin is set to 5 mm (848), and the process proceeds to S49.

In S49, it is determined whether the frame erase key 94 is ON.

ON, and if the LED 94a is ON (S50),
L to cancel the currently set frame tF15mm.
Turn on the ED94a, turn on the FFXLED94b, set the frame eraser to 10mm (S51), and proceed to S57. If the LED 94b is ON (S52), the LED 94b is turned OFF and the LED 94c is turned ON to cancel the currently set frame eraser of 10 mm, setting the frame eraser to 15 mm (S53), and the process proceeds to S57. LED94c or ON
If so (S54), the currently set frame eraser 15
In order to cancel mm, the LED 94c is turned off, the frame erase mode itself is canceled (S55), and the process proceeds to S57. L
If all EDs 94a, 94b, and 94c are OFF, that is, if the frame erase mode is canceled, L E D
94 Turn on a and set the frame eraser to 5mm (S5
6), proceed to S57.

In S57, it is determined whether the book division copy key 95 is ON. ON, and if the LED 95a is ON (S58), turn off the LED 95a to cancel the set book split copy mode (S58).
59), proceed to S61. Conversely, if the LED 95a is OFF, the LED 95a is turned ON, the book division copy mode is set (S60), and the process proceeds to S61.

In S61, all reset/stop key 91 or ON
At this stage, since it is a non-copy operation (copy flag -O), this is determined to be an all-reset, and the copy counter is set to 1 (S62) to return to the initial state.
), the 1st place flag is set to 1 (S63), and the 10th place flag is set to O (S64). And LED93a
-93c, 94a-94c, and 95a are turned off, respectively, and all modes of binding margin, border erasure, and book division copying are canceled =15- (S65). Thereafter, the value of the copy counter is displayed on the display section (866), and the process returns.

■Panel control during copy operation On the other hand, if copying is in progress, the copying flag is set to l as shown at 373 in FIG. 7, so the panel control routine jumps to S34 through S21. .

Then, it is determined whether the all reset/stop key 91 is ON (S34), and if it is ON, it is regarded as a stop and the stop flag is set to 1 (S35).
, display the value of the copy counter on the display unit 70 (S6
6.Refer to FIG. 6(d)), return. If the all reset/stop key 91 is OFF, the display section 7
The value of the copy counter is displayed at 0 (S66), and the process returns.

This S34. S35. S66 is always repeatedly executed, regardless of whether a copy operation is performed or a non-copy operation is performed, and determines whether the all reset/stop key is 0N10FF.

(1-4, Copy operation Figures 7 (a) to (C) are flowcharts of the copy operation routine.During this copy operation routine, the panel control routine is executed to determine whether the all reset/stop key is 0N10FF. It's working.

When the print key 75 is pressed (S71), the copy start flag is set to 1 (S72)L, and the copying flag is set to 1 (S73).

Then, if the copy start flag is 1 (S74), the main motor, developing motor, charging charger, and transfer charger are each turned ON, and timer A that sets the ON period of the paper feed roller clutch and the waiting time until scanning are set. Set timer B for each. Further, the copy start flag is reset to O (S75). Then, if the first paper feed is selected (S76), the first paper feed roller clutch is turned on (S77), and if the second paper feed is selected (378), the second paper feed roller clutch is turned on. O
N (S79). Then, when timer A ends (S
80), turn off the first and second paper feed roller clutches (
S81). Next, wait for the end of timer B (S82),
The scan signal is turned on (S83). Next, if the timing signal from switch SW5 is generated,
84), turn on the timing roller clutch,
The timer C for setting the waiting time is set seven times (S85). Wait for timer C to end (386), turn the charger and timing roller clutch to 0FFL, and set the scan signal to 0.
(S87).

When the optical system returns, and the return signal is ON (S88), the copy counter is decremented (S89).

When the copy counter reaches 0 (S90), copying of the preset number of stitches has been completed, so the copy counter is returned to the initial value of 1 (591), and the copying flag is set to 0 (S90).
92), the stop flag is set to O (S93). If the copy counter is not 0 (S90), and the stop flag is "0" because the set number of copies have not been completed (S94), the copy start flag is set to 1 to continue copying. If the stop flag is ``l'', the copying flag and stop flag are set to ``0'' (S92, 593).

Next, the determination of whether a return signal has been generated is made again (896).
When the return is started and the scanner that left the -degree localization value returns and the localization value sensor switch 5W5Q is turned on (S97), the developing motor and transfer charger are set to 0FFL (S98), and the copying flag is set to 0. if there is,
A timer D is set to wait for a time to turn off the main motor (S100). If the copying flag is l (
S99), since there is no need to stop the main motor, timer D is not set to 1. Wait for timer D to end (S I Ol) and turn off the main motor (S10
2) Output the results of the processing up to now (Si20) and return.

Note that if the All Reset/Stop key 91 is pressed during copying, the panel control! - The stop flag becomes 1 in S35 of the roll routine, and the next copy operation routine can be stopped.

(Effects) As shown below, the operation panel of the 'fν photographic machine of the present invention has the following effects:
Use both the all reset key and the stop key.

The dual-purpose key works as a stop key during copy operation,
It works as an all-reset key while copying is not working, so
By reducing the number of keys, manufacturing costs can be lowered and the operation panel can provide a better appearance.

In addition, we have taken into account the user's psychology when they want to cancel the copying operation if they have set the copying conditions incorrectly, that is, (stopping the copying operation) is equivalent to (resetting the copying conditions). , Is it user-friendly?
It also has the effect of becoming.
