Abstract

PURPOSE:To reduce the number of copying errors by selecting and displaying only a copying mode where a selected copying mode and a copying mode in the initial state are noncoincident therewith. CONSTITUTION:When the copying mode selected by a copying mode specifying means and the copying mode in the initial state specified by an initial mode setting control means are noncoincident after the end of copying is discriminated by a copying termination discriminating means, only the noncoincident copying mode is selected and displayed by a display means. Therefore, even if a copying person has changed at the end of a copying action, only a mode different from a former copying mode that a former person has specified and the copying mode in the initial state are selected and displayed. Therefore, the copying person may know the difference between copying mode in the initial state and his specified mode, and the number of copying errors can be reduced.

Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a copying machine, and in particular, to a copying machine that displays a display according to a selection or setting input when selectively setting an arbitrary copy mode and performing a copying operation. The present invention relates to a copying machine designed to perform this function.

[Prior Art] Some copying machines of this type conventionally enter a standby state in a designated copy mode when a predetermined period of time has elapsed after copying operations and key operations have been completed.

That is, when a predetermined time has elapsed after the copying operation and key operation are completed, it is assumed that the use of the copying machine has ended, and the copying machine is placed on standby in a predetermined initial state. This initial state of waiting can be set 52 for a particular mode.

In this way, when the copy operation and key operation are completed,
The reason why the device is set to standby in the initial state after a predetermined time has elapsed is that by changing the standby state to a predetermined [P] mode, it is possible to reduce the number of check items and setting items before use.

Furthermore, even if the person making the copy changes without each other's knowledge, copying can be done in the copy mode of the person who made the copy before, thereby preventing copy mistakes from occurring. Note that, normally, in the copy mode in the initial standby state, the number of copies is set to be small, for example, one copy, in order to reduce the number of erroneous copies.

[Problems to be Solved by the Invention] However, since this type of copying machine supports continuous use by users, when a specified copy mode is selected and a copy is made, a predetermined amount of time has elapsed since the end of the copy. Since the copy mode is later switched to the initial state, the copy mode set at the time of copying is maintained from the end of copying until switching to the initial state copy mode, and the person making the copy during this time If the is replaced,
There was a problem in that the copy was made in the copy mode of the previous user, resulting in a copy error.

Additionally, copying machines that do not have an auto-clear function remain in the previously set copy mode except when the power is turned on or when performing an all-clear operation, so the possibility of such erroneous copies is even greater. It's large.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and it is an object of the present invention to provide a copying machine that can reduce the number of erroneous copies made by the copying machine after the copying operation is completed.

[Means for Solving the Problems] A copying machine according to the present invention includes a display unit for displaying and covering a copy mode selected and set by a copy mode specifying unit for selecting and setting a predetermined copy mode, and a display unit for determining the end of a copy operation.
6. Copy end determining means; initial mode setting control means for setting the copy mode specifying means to a specified initial state; and when the copy end determining means determines that the copy operation has ended, the copy mode specifying means When the copy mode selected in and the initial state copy mode specified by the initial mode setting control means do not match,
The display control means selectively displays only the mismatched copy modes on the display means.

[Operation] In the present invention, the copy code selected by the copy code specifying means is displayed by the display unit, and the copy code selected and set by the copy code specifying means is displayed, and the copy code selected and set by the copy code specifying means is displayed. When the copying operation is completed, the copying completion determination means determines whether the copying operation is completed or not. - On the other hand, the initial mode setting control means is
The copy mode specifying means is set to a specified initial state.

When the end of copying is determined by the copy end determining means, if the copy mode selected by the copy mode specifying means and the initial state copy mode specified by the initial mode setting control means do not match, the display means displays the copy of the mismatched copy. It selectively displays only the modes.

Therefore, even if the person making the copy is changed after the copy operation is completed, by selectively displaying only the copy mode of the previous person who made the copy and the mode that is different from the initial state copy mode, the initial state copy mode can be changed. The person making the copy can be informed of the difference between the two, and the occurrence of copy mistakes can be reduced.

[Embodiment] FIG. 1 is a schematic configuration diagram showing the configuration of a copy machine according to an embodiment of the present invention. Note that the mechanical configuration and copying operation of a copying machine are well known, and the present invention Since this is not directly related to the gist of the article, I will only explain it in the text.

After the transfer, residual toner is removed from the photosensitive drum 3 by a cleaner 9, residual charge is removed by a main eraser lamp 4, and the photosensitive drum 3 enters the next copying process.

The copying machine that operates as described above repeats the above-described copying operation in accordance with the number of copies set by the operator prior to the copying operation, and then stops when a predetermined time rF', J has elapsed.

The main motor M1 drives the photosensitive drum 3, paper feed/discharge system 20, etc., and the scanner motor M4 drives the optical system. Further, the magnification setting motor M3 displaces the variable magnification lens 15 to change its magnification. A developing motor M2 (not shown) drives the developer la6.

FIG. 4 is a flowchart of a main routine for controlling the first microcomputer CPU1 serving as a host computer of a copying machine according to an embodiment of the present invention.

First, in step MO, initial settings are performed by turning on the power. In step M1, an internal timer that defines the time required for one routine of the main routine is started. After that, in step M2, a "copy operation routine", which will be described later, is called, in step M3, "copy start and end processing routine", in step M4, "copy end processing routine", and in step M5, "A-1-clear processing routine", In step M6, a ``display routine'' is called, and in step M7, an ``other processing routine'', the explanation of which is omitted here, is called, and in step M8, one routine is completed after waiting for the internal timer to end.

It should be noted that the length of time for one routine is determined by the timers used in the various routines described above. That is, the end of each of these timers is determined based on how many times this routine has been executed.

Furthermore, data communication sent from the first microcomputer CPU1, which is the host computer, to the second microcomputer CPU2 is performed in each routine! 22! This is performed independently of the main routine processing in response to an ^1j import request from the first microcomputer CPU1 every time the program is completed.

FIGS. 5 and 6 are flowcharts showing details of the "copy operation routine" of step M2.

In this routine, by operating the print start key 40,
Copying is performed on a predetermined paper.

First, in step S1, it is determined whether the print star l-key 40 is on-edge. When an on-edge signal is obtained,
In step 5, a copy start flag is set and the process returns to the main routine. On the other hand, if it is not on-edge in step S1, it is determined in the next step S2 whether or not an in-operation flag indicating that a copy operation is in progress is set, and if the in-operation flag is not set, in step S3 select routine" to select a predetermined magnification, and step S4
Process the "Paper Selection Routine" to select a predetermined paper size. Following step S4, a copy start flag is determined in step S6, and when the copy start flag is set, in step S7, the developing motor M4, the charging charger 5, and the transfer charge V7 of the main motor ML developing device 6 are turned on. , the copy start flag is lowered, and timer TA and timer TB are set to star I.
and put the copying machine into operation. Furthermore, the timer TA sets the clutch off time of the paper feed rollers 22A of the automatic paper feed force cellars 1 to 21A and the paper feed roller 22B of the automatic paper feed cassette 21B from cell number 1 to 1, and the timer TB sets the scan opening time of 17. It is something to do.

In step S8, it is determined whether the upper automatic paper feed cassette 21A is selected, and if the automatic paper feed cassette 21A is selected, the clutch of the upper paper feed roller 22A is turned on in step S9. Also, step 310
In step 311, it is determined whether the lower automatic paper feed cassette 21A is set, and if the lower automatic paper feed cassette 1 to 21A is selected, the lower paper feed roller 22B is set.
Turn on the clutch. Then, in step S12, it is determined whether the timer TA has elapsed, and when the time limit set in the timer TA has elapsed, in step S313, the paper feed roller 22A is
Alternatively, the clutch of the paper feed roller 22B is turned off to stop feeding the paper. Further, in step 314, the elapse of the timer "B" is determined, and when the time limit set in the timer TB has elapsed, the scan signal (scan start signal) output to the second microcomputer CPU2 is set to "1" in step 315. do.

Note that the second microcomputer CPU2 starts an exposure scan upon receiving the signal. The exposure scan performed by the second microcomputer CPU2 is not directly related to the gist of the present invention, so its explanation will be omitted.

Once the optical system 10 reaches the predetermined position in step 316,
The second microcomputer CF) judges the timing signal output from U2. The timing signal is “
1'', the clutch of the timing roller 26 is turned on in step 317, the paper is fed between the photosensitive drum 3 and the transfer charger 7, and transfer to the paper is started. , the timer TC is started at 1-.The timer TC is set at the scanning end time,
This is a timer that sets the charging end time and the clutch off time of the timing roller 26, and the times are determined by the size of the paper selected in steps 88 to 311 and the set copy rate. .

In step 318, it is determined that the timer TC has ended, and the timer T
When the time limit set in C has elapsed, step 319
Turn off the charger 5 and set the scan signal to “0゛′,
The return signal is set to "1" and the clutch of the timing roller 26 is turned off. Then, in step 320, it is determined whether the return signal is "1".

If the return signal is "1pa" in step 320, it is determined in step 321 whether the multi-copy is finished. If the multi-copy is finished, in step 322, the reference position signal is output from the second microcomputer CPU2. is "1", it is determined that the optical system 10 has returned to the reference position, and in step S23, the developing motor of the developing device 6 and the transfer charger 7 are turned off, and the return signal is "1".
It was made O゛', and furthermore, timer TD became a star! ~ will be done.

On the other hand, if the multi-copy is not completed in step 321, it is determined that the optical system 10 has returned to the reference position because the reference position signal is "1" in step 324, and the return signal is "0" in step 325. '', and furthermore, in step 326, the copy start flag is set again (“one pass is interrupted”).Then, in step 327, the end of timer TD is waited for, and then in step 32B, main motor M1 is turned off, and step In step 329, each control signal of the external device is output.In addition, in step 824, the reference position signal is
If not 1'', step 325 and step 326
The process proceeds to step S27 without performing the process, and then waits for the reference position signal to become "1".

In this way, the copy operation is performed.

The "magnification selection routine" in step S2 and the "paper selection routine" in step $3 are performed as follows.

FIG. 7 shows the "magnification selection routine" in step S2 above.
This is a flowchart showing the details of.

This routine selects the paper corresponding to the size of the yA manuscript by using the A3→A71 reduction magnification select key 80, A3→B4

At step 363, A3 → A4 reduction A8
Set the rate. Further, in step 364, it is determined whether the A3→B4 reduction ratio select key 82 is on edge, and when the on edge is obtained, the A3→B4 reduction ratio display 83 is turned on in step 365, and it is set in step 366. In step S67, it is determined whether the A4→A3 enlargement magnification select key 84 is on-edge, and when the on-edge is obtained, the A4→A3 enlargement magnification display 85 is determined in step S67.
and set it in step 369. In step 370, the on-edge of B4→A3 enlargement magnification selection l-4=-86 is determined, and when that on-edge is obtained,
In step 371, the B4→A3 enlargement A8 ratio display 87 is turned on, and in step 372, it is set. Also, in step S73, it is determined whether the same size selection key 88 is on-edge,
When the on-edge is obtained, the same size display 89 is turned on in step 374, it is set in step 875, and the standard A8 rate flag is lowered in step 376.
When the on-edge of the equal magnification select key 88 is not 17 at step 73, the process returns without lowering the target magnification flag.

FIG. 8 is a flowchart showing details of the "paper selection routine" in step S3.

In this routine, the paper selection key 70 is operated to select the automatic paper feeding force cera 1 to 1 for a predetermined paper.
Paper selection is performed in a rotation of A3→B4→A4→B5→A3, but in this embodiment, only two automatic paper feed cassettes 21A and 21B are installed. From, automatic paper feed force Cera I-21A
Alternatively, the paper stored in the automatic paper feed cassette 2113 is alternately selected.

In step 381, it is determined whether the paper select key 70 is on-edge, and in step 3B2, the standard paper size flag is lowered, and if the on-edge signal is not turned on (19), no selection is made and the process returns. When the on-edge signal is determined, it is determined in step 383 whether the current display is F3 size, and if A3 size is being displayed, or if A3 size paper, B4 size, A4 size paper is displayed in step S98.
If it is not determined that all of the sizes B5 and B5 are missing, the soft S84 determines whether 84 size paper is stored, and if there is B4 size paper, 84 is displayed in step 385, and step 386
Configure the 84 paper settings using .

Also, if the current display is not A3 size in step 383, it is determined in step 387 whether the current display is B4 size, and if B4 size is displayed, and if 84 size paper is accommodated in step 384. When it is determined that there is no A4 size paper stored, it is determined in step 38B, and if A4 size paper is stored, A4 size paper is displayed in step 889.
In step 390, settings for A4 paper are made. and,
If the current display is not 84' size in step 387, it is determined in step 391 whether the current display is A4 size, and if A4 size is displayed, and if A4 size paper is stored in step 388. When it is determined that there is no B5 size paper stored, it is determined in step 392, and if there is B5 size paper, 85 is displayed in step S93, and 85 paper is set in step S94. . Further, when it is determined in step S91 that the current display is not A4 size, and when it is determined in step 392 that 85 size paper is not accommodated, in step 395, A3 size paper is not stored.
) Determine whether J-is paper is stored, and then
If the printer has paper of the same size, A3 display is performed in step S96, and A3 paper is set in step S97. Then, if it is determined in step S95 that no A3 size paper is stored, in step 398, A3 size paper is not stored.

When it is determined that all of the papers of J is missing, this routine is exited and the process returns.

In this way, each time the paper select key 71 is turned on (A), A3→B4→A4→B5. →Since it is programmed to rotate A3 sequentially, B4
! When J-size and B5υ size papers are stored, the settings are alternately switched from B4→B5→B4→B5. At step 398, A3, B4, A4, B5
Returns when all the papers in are not stored.

In the above embodiment, after copying is completed, a warning is displayed for the mode that is not in the standard state, and if a key is operated before auto-clearing, the display is returned to the normal display. By eliminating this process, it is also possible to always display a warning if a key is not in the standard state even if a key is pressed after copying is complete.

FIG. 9 is a flowchart showing details of the "copy start and end processing routine" in step M3.

In this routine, it is determined whether the copying operation of the copying machine has ended or whether the copying operation is in progress, and this is stored in the in-operation flag and the end flag.

First, in step 3101, it is determined whether the in-operation flag indicating that the copying machine is in operation is off. When the in-operation flag is off, the state of the copy start flag set in the process of the "copy operation routine" is checked in step 5102, and if the copy start flag is set, the in-operation flag is set in step 5103, and the step In step 3104, the standard magnification flag, standard paper size flag, standard exposure flag, and standard number of sheets flag are removed. Further, in step 5105, the auto clear timer is cleared. This routine sets an in-operation flag by performing a copy operation even once. When the in-operation flag is set by performing a copy operation, step 51 in the next routine is performed.
Based on the determination of the in-operation flag of 01, it is determined that the in-operation flag is set, and in step 8106, it is determined whether processing of a predetermined designated number of sheets has been completed. Note that step 51
Similar to step 321 in FIG. 6, the determination in step 06 is made at the time when the scan is completed. This is because the present embodiment is configured so that each weighing parameter can be input from the time when the final multi-copy scan is completed. When the processing of a predetermined designated number of sheets is completed, the in-operation flag is lowered in step 3108, and the end flag is set in step 3109. Further, when it is determined in step 8106 that the processing for the predetermined number of copies has not been completed, in step 5107, during the copying operation for the predetermined number of copies,
It is determined whether the interrupt key 56 or the clear stop key 57, which interrupts the operation or interrupts copying of another number of sheets, is operated, and
When is operated, the in-operation flag is lowered in step 3108 and the end flag is raised in step 3109, as if processing of a predetermined designated number of sheets has been completed. That is,
Even when the interrupt key 56 or the clear stop key 57 is operated, a process is performed in which the difference from the predetermined standard magnification, standard paper size, standard exposure, and standard number of copies is determined, and only the mode with the difference flashes. conduct.

FIG. 10 is a flowchart showing the details of the "copy end processing routine" in step M4.

In this routine, when the copying operation is completed or the copying operation is interrupted by operating the clear/stop key 57, the current copy mode is set as the initial state of standard magnification, standard paper 1 noise, standard exposure,
It determines the difference from the standard number of copies, sets a flag only for the mode with the difference, and stores it.

First, in step 831, it is determined whether the end flag is set, and if the end flag is not set, this routine is exited. As soon as the end flag is set, in step 333, the current A3 select i/display 71, B4 select display 72,
Depending on the output status of the A4 selection display 73 and the B5 selection display 74, the standard paper size (in this example, A4
(J size is determined. If it is not the standard paper size, a standard paper size flag is set in step 334. Then, in step 335, the output status of the exposure level display 46 to 54 of the LED row for displaying the current image density It is determined whether the exposure level is the standard exposure level (center in this embodiment).If the exposure level is not the standard exposure level, step 836
Set the standard exposure flag with .

Furthermore, in step 837, it is determined based on the current output state of the data displayed on the glyph display section 41 whether the standard number of sheets (in this embodiment, one sheet) is reached. If the number of sheets is not the standard number, a standard number of sheets flag is set in step 338. Then, in step 339, the current A3→A4 reduction magnification display 81, A3→B
4 reduction A8 ratio display 83, A4 → A3 enlargement magnification display 85,
Based on the output status of the B4→A3 enlargement magnification display 87 and the equal A8 display 89, it is determined whether the magnification is standard (in this embodiment, equal magnification). If it is not the standard A8 ratio, a standard magnification flag is set in step 340. After determining these copy modes, in step S41, an auto clear timer that clears the copy mode of the copying machine to the initial state after a predetermined period of time has passed is started.

FIG. 11 is a flowchart showing details of the "A-to clear processing routine" in step M5.

This routine determines the elapsed time of the auto clear timer that clears the copy mode of the copier to its initial state after the end of a role or after a key on the operation panel 2 is operated, and In addition to clearing the mode to the initial state, it also erases the memory of a flag for flashing a mode different from the mode set as the initial state from the end of the copy operation until the copy mode is cleared to the initial state. Incidentally, when the copying is completed, the auto clear timer is started in step S41 in FIG. 10.

In step 351, the keys on the operation panel 2 are operated.

The off edge is 1!7.
If so, the auto clear timer is started from 1 in step S52. Note that this auto-clear timer is cleared in step 5105 of the "copy start/end processing routine" when continuous copying operations are performed. If the off-edge is not obtained, wait for the auto clear timer to end in step 353, and when the auto clear timer ends,
In the standard mode in which the copy mode is set as the initial state in step S54, that is, in this embodiment, the standard magnification is equal to
The standard paper size is set to A4, the standard exposure is set to center, and the standard number of sheets is set to 1.The mode is set as the initial state, and there is no need for a blinking display, so step 355
Use to lower the standard magnification flag, standard paper size flag, standard exposure flag, and standard number of sheets flag.

FIG. 12 is a flowchart 1 showing details of the "display routine" in step M6.

In this routine, the standard magnification flag, standard paper size flag, standard exposure flag, and standard number of sheets flag are checked, and a blinking display is performed in accordance with the set flags.

First, in step 5111, it is determined whether the standard magnification flag is off, and when the standard magnification flag is off, the LED that displays the selected magnification in step 5112, ie, A3→B4 reduction magnification display 81, A3→ B4 reduction magnification display 83, A4→A3 enlargement magnification display 85, B4. →The A3 expanded occupancy rate display 87 lights up continuously to display the setting. Further, when the standard magnification flag is set, the selected magnification is displayed blinking (flick display) in step 5113.

Then, in step 5114, it is determined whether the standard paper size flag is off, and when the standard paper 1 noise flag is off, the LED that displays the selected paper 1 noise is turned on in step 5115, that is, A3 select I~ The display 71, B4 select display 72, Δ4 select display 73, and B5 select display 74 are lit continuously to display the settings. Further, as long as the standard paper size flag is set, the selected paper size is displayed blinking in step 8116.

In step 5117, it is determined whether the exposure flag is off, and if the standard exposure flag is off, step 81
The exposure level displays 46 to 54 of the LED row for displaying image density selected at 18 are continuously lit to display the settings. Further, when the standard exposure flag is set, the exposure level selected in step 5119 is displayed blinking.

In step 3120, it is determined whether the standard number of sheets flag is off, and if the standard number of sheets flag is off, step 512
The setting is displayed by continuously lighting up the number display of the glyph display section 41 selected in step 1.

Also, when the standard number of sheets flag is set, step 51
The number of sheets selected at 22 is displayed blinking.

As described above, the copying machine of this embodiment includes a copy mode specifying means for selecting and setting a predetermined copy mode by operating various keys on the operation panel 2, and an LED indicating the copy mode selected and set by the copy mode specifying means. a display means that lights up at ``copy start and end processing routine'', a copy end determination means that determines the end of the copy mode by processing such as the ``copy start and end processing routine'', and a copy end determination means that determines the end r of =1 bee; an initial mode setting control means for setting the copy mode specifying means to a specified initial state after a predetermined time set in the O1-clear timer in "O1-Clear Processing Routine"; If the copy mode specified by the initial mode setting control means does not match the initial state copy mode specified by the initial mode setting control means, the initial mode setting control means changes the mode determined by executing the copy end processing routine J to the initial state from the end of copying. and a display control means for selectively displaying only the mismatched copy modes on the display means by executing a "display routine" until the copy mode is set.

Therefore, in this embodiment, the copy mode selected and set by the copy mode specifying means can be displayed by the display means.

Further, a copy operation is performed in accordance with the selected copy mode, and when the copy operation is completed, it is determined by a copy completion determination means, and the copy mode designation means is designated by an initial mode setting control means after a predetermined period of time has elapsed. It can be set to the initial state.

Then, until the initial mode setting control means sets the copy mode specifying means to the specified initial state after a predetermined period of time has elapsed, the copy mode selected by the copy mode specifying means and the copy mode specified by the initial mode setting control means are set. When the initial copy mode does not match,
The display control means can selectively display only the mismatched copy modes on the display means.

Therefore, even if the person making the copy changes between the end of the copy operation and the switch to the initial copy mode, only the copy mode of the previous person and the mode that is different from the initial copy mode will be selected. By displaying this, the person making the copy can be informed of the difference from the initial copy mode, and the occurrence of copy mistakes can be reduced.

By the way, the copy mode specifying means for selecting and setting a predetermined copy mode in the above embodiment and the display means for displaying the copy mode selected and set by the copy mode specifying means collectively perform key operations and display on the operation panel 2. However, when implementing the present invention, the copy mode designating means and the display means may be arranged in any manner.

In the above embodiment, when the selected mode is different from the initially set mode, this is indicated by a blinking display, but other display forms may be used. for example,
This can be done by changing the display color, or by displaying a message indicating that the mode is different from the initial setting in a copying machine that has a message display.

Further, in the above embodiment, the copy end determination means for determining the end of the copy mode is performed by executing the "copy start and end processing routine", but when implementing the present invention, the copy operation Since it is sufficient to detect the end, it can be used as a means for detecting the end of copying a predetermined number of sheets, the end of the main motor, etc.

Further, when implementing the present invention, the initial mode setting control means determines the end of copying by the copy end determination means of the above embodiment and sets the copy mode designation means to a designated initial state after a predetermined period of time has elapsed. For this purpose, a known auto-clearing means can be used.

Further, when the copy mode selected by the copy mode specifying means and the initial state copy mode specified by the initial mode setting control means do not match, the initial mode setting control means controls the copy mode from the end of copying until the initial state is set.
The display control means for selectively displaying only mismatched copies '[-' on the display means indicates that the copy mode selected by the copy mode specifying means and the initial state copy mode specified by the initial mode setting control means do not match. ``=1
The mode determined by executing the printing process routine J is stored in the standard magnification flag, standard paper is flag, standard exposure flag, and standard number of copies flag, and the initial mode setting control means determines the copy mode by looking at the flags. From the end until the initial state is set, only the mismatched copy mode is flashed on the display means by executing the "display routine", and by the normal continuous lighting and flashing display,
This shows the difference from the standard mode in which copy mode is set as the initial state. However, when implementing the present invention, the present invention is not limited to the above embodiments, and the copy mode is compared with the standard mode set as the initial state, and only the modes different from the mode set as the initial state are compared to the normal mode. It is sufficient if the difference from the standard mode can be expressed by a display different from the display.

In addition, in the above embodiment, a warning is displayed after copying is completed and until auto clear is activated.
For copying machines that do not have an auto clear function, the copy end
Afterwards, a warning may be displayed until the user performs some key operation or until everything is returned to the standard mode.
