Abstract

PURPOSE:To make the best use of a memory by counting the number of different copying conditions when copying is performed according to a copying program, comparing the counted value with a predetermined decision value and deciding whether or not input copying conditions are stored as the copying program. CONSTITUTION:According to a prescribed control program, a CPU 31 controls each part of a copying machine main body 40 based on data inputted from a console display panel 1 and instructs the part to take a copy. At this time, copying conditions stored beforehand in the copying program are compared with copying conditions which are about to be stored as the copying program, and the number of different conditions is calculated. If the number exceeds the decision value, the copying program to be stored is stored through a depressed memory key, whereas if the number is below the decision value, the copying program to be stored is not stored. Thus, the memory can be utilized effectively.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a copy control device capable of storing copy conditions set by key operations.

[Prior Art] In recent years, copying machines equipped with various copying functions such as image reduction and enlargement, double-sided copying, page speed copying, etc. have been on the market.

In such copying machines, a large number of key switches and displays are provided on the operation display panel for selecting each of the above-mentioned functions, and therefore, the operator must operate each of these key switches. However, it is troublesome to set a desired copying mode, resulting in problems such as poor operability of the copying machine. In particular, high-speed copying machines often have the disadvantage that the time required to set the copy mode is longer than the actual copy time.

In order to solve this troublesome key switch operation,
A device has been proposed that stores a plurality of copying conditions as one copying program in RAM, calls this copying program at the time of arbitrary copying, and controls the copying operation according to the copying program (Japanese Unexamined Patent Publication No. 59-91455 and Publication No. 59-222854). A plurality of such copy programs can be stored for convenience in setting copy conditions.

[Problem that the invention seeks to solve]

This copying program can be easily inputted by the operator. Therefore, a plurality of copying programs with the same copying conditions may be stored in the RAM. If a plurality of copying programs with the same copying conditions are stored in this way, the memory will not be used effectively.

The present invention has been made in view of these points,
An object of the present invention is to provide a copy control device that does not store a plurality of copy programs in which the same copy conditions are set.

[Means for solving problems]

In order to achieve the above object, the copying control device of the present invention includes a storage means capable of storing a plurality of arbitrary copying conditions set by key operations as one copying program, and selecting one of the stored copying programs. a selection means, a control means for controlling copying according to a copying program called up by the selection means, a copying condition determining means for determining a difference in copying conditions between a stored copying program and a copying program to be stored, and a copying condition. and a memory determination means that compares the counted value with a predetermined determination value and determines whether or not the input copying conditions are to be stored as a copying program. .

[Effect]

Copy conditions to be stored as a copy program are set by operating keys on the operation display panel. Then press the memory key you want to set. Then, the microprocessor compares the copying conditions to be stored as a copying program with the copying conditions of the already stored copying program, and calculates the number of different conditions. If the number of different copy conditions is greater than or equal to a predetermined judgment value, for example,
2" or more, the copy program you are trying to store is stored in the pressed memory key, and if the number of different copy conditions is less than a predetermined judgment value, for example "1" or less, the copy program you are trying to store is stored in the pressed memory key. The current copying program is not memorized.

, the margin selection key 15, and the sorter selection key 16. Light-emitting diodes L are arranged adjacent to each of the keys 15, 15, and 16, and are indicators for indicating the copying conditions set by operating each key.

For double-sided copying, divided copying, and margin copying, each mode of double-sided copying from a double-sided original, double-sided copying from a book original, and double-sided copying from a single-sided original can be sequentially changed by operating the double-sided copy selection key 13 by operating the divided copy selection key 14. By operating the margin selection key 15, the positions (right side, left side) in which the binding margin is to be created are set in sequence for each mode of dividing copy from a double-sided original and dividing copy from a book original. Furthermore, by operating the sorter selection key 16, sort mode, group mode, and non-sort mode are sequentially set.

After the duplex copy mode, split copy mode, and margin copy mode for double-sided copy from a single-sided original, split copy mode from a book original, and mode for the binding margin position (left side) are set, each selection key 13, When 14 and 15 are operated, the display will not light up and copying conditions will not be set.

Further, the operation display panel 1 is provided with a program key 17 and three memory keys 18, 19, and 20 for specifying a memory area of the RAM for storing programmed copying conditions.

L1, L2, and L3 are memory indicators consisting of light emitting diodes provided corresponding to each memory key 18, 19, and 20.

When the power is turned on, the display on the operation display panel 1 (hereinafter referred to as the initial display) shows "rl" on the sheet count display 5, "4" level on the density level display 7, and "A4" paper feeding power. The display 100% is displayed on the magnification display 12, and the non-sort display 12 is driven and displayed on the sorter, and their copying conditions are set.

FIG. 4 shows a control unit 30 of a copying machine according to an embodiment of the present invention.
is exemplified. In the figure, the control unit 30 is a CPU
(Central processing unit) 31, R with control program written ↑
The OM 32, the RAM 33 which is a data storage unit and work area of the CPU 31, and the operation data of the operation display panel 1 described above are input to the CPU 31, and the CPU 31
l10 outputs the display data outputted by to the operation display panel 1.
It consists of 34 (including input/output circuits and interfaces).

The CPU 31 controls each part of the copying machine main body 40 to perform a copying operation based on data input manually from the operation display panel 1 and according to a predetermined control program. The copying machine main body 40 is naturally equipped with elements for realizing the functions selected by the operation keys on the operation display panel l shown in FIG.

1 to 3 are flowcharts generally showing the flow of control by the control section 30 in FIG. 4.

Figure 1 shows a flowchart of copy program settings;
When the program key 17 is pressed (step Sl),
Enter the copy program setting mode, turn off all the indicators 7 and L on the operation display panel 1 (step S2), and press the memory keys 18 and 9 to which the copy program has already been set.
．． The memory indicators L1, L2, and L3 corresponding to No. 20 are turned on (step S3). Therefore, the memory display corresponding to the memory key to which no copy program is set is turned off. Then, in step S4, the operator performs key operations to set copying conditions that are desired to be stored as a copying program. Alternatively, the user operates the clear key 4 to rewrite the copy program stored in any one of the memory keys 18, 19, and 20 for reasons to be described later. In step S5, it is determined whether the clear key 4 was pressed in step S4, and if it was not pressed, the display 7.
12, L is turned on in accordance with the set copying conditions (step 36). In order to store the set copy conditions as a copy program, one of the memory keys 18, 19, and 20 is pressed (step 37). If there is a memory key in which no copy program is stored (step S3
(visually visible in the display format), press that key.

When a memory key is pressed in step S7, the memory display corresponding to the key is turned on, and the other memory displays are turned off (step S8). Then, in step S9, the copying conditions to be stored as a copying program are compared with the copying conditions of the copying programs already stored in the memory keys 18, 19, and 20, and the number of different conditions is calculated. Then, the calculated number of differences in copy conditions is compared with the judgment value, and the number of differences in copy conditions is "2".
If the above is the case (step 510), the copy conditions set in step S4 are set as a copy program in the memory key pressed in step S7 (step 511).
. That is, the contents of the memory area of the RAM 33 corresponding to the memory key pressed in step S7 are rewritten. Then, in step S7, the contents of the history area corresponding to the pressed memory key (described later) are cleared (step 51
2).

Also, in step SIO, the number of different copy conditions is "0".
", that is, the copying program with the same copying conditions is stored in memory key 1.
8.19.20, the process moves to step S13, and the memory display corresponding to the memory key to which the same copying program is set blinks. This display form is maintained for a period of time during which the operator can recognize that the same copying program has already been set to a specific memory key (step S14.515). And step S1
6, the memory indicator of the memory key pressed in step S7 is turned off, the blinking memory indicator is turned on, and the copy program R set in step S4 is turned off.
Writing to AM33 is not performed (step 517).

Furthermore, if the number of different copying conditions is rl in step 310, the process moves to step SI8, and it is determined whether the frequency of use of the copying program set in the memory key pressed in step S7 is within a predetermined value. This frequency of use is measured based on a flowchart shown in FIG. 2, which will be described later, and here, if the frequency of use is within 5 times when the print key 2 is pressed 50 times, the process moves to step S19.
In step S7, the memory display of the pressed memory key is turned off, and the memory display of the memory key to which a similar copying program is set is blinked.

Then, the similar copying program is rewritten to the copying program set in step S4 (step 520).

That is, the copy program with the copy conditions set in step S4 is stored and set in the flashing memory key in step S19. Then, the contents (described later) of the history area corresponding to this memory key are cleared (step S21).
). After the display form of step 319 is maintained for a predetermined time in steps S22 and S23, the blinking memory display is switched to a lit display (step 524), and the memory key stored and set is displayed to the operator.

If it is determined in step 31B that the frequency of use of the similar copying program is 5 times or more, the process moves to step S25, where the memory display of the memory key to which the similar copying program is set blinks, and one different copying condition is set. The display is made to blink (step 326). These display modes are then displayed for a predetermined period of time (step S27.528). This time setting may be any time necessary for the operator to recognize the memory key to which the similar copying program is set and one different copying condition. Next, in step S29, the memory display of the memory key pressed in step S4 is turned off, and the blinking memory display is switched to a lit display. Therefore, if a frequently used copying program exists, the copying program with the copying conditions set in step S4 will not be set.

When the series of processes for setting the copy program is completed, the program key 17 is pressed again (step 530) to cancel the copy program mode. When the copy program mode is released, the display format of the operation display panel 1 is changed to the initial display (step 531).

In the key operation in step S4, if there is a reason that the copying conditions to be set must be stored as a copying program, the clear key 4 is pressed. When any of the memory keys 18, 19, and 20 is pressed after pressing the clear key 4 (transition from step S4 to S5 to S32), the copy program set to the pressed memory key is erased (step 533). ). Alternatively, it becomes possible to write a copy program. Then, when the copying conditions are set by key operation (step 534), the display 7.12, L corresponding to the set copying conditions is lit (step 535), and the copying conditions are written into the RAM 33. When the copy program is stored, the contents of the history area corresponding to the memory key pressed in step S32, which will be described later, are cleared (step 537). and program key 1
Press 7 (step 530) to cancel the copy program mode.

In order to immediately execute a copying operation using this copying program after setting such a copying program, an operation based on a copying program call setting control flowchart to be described later may be performed.

In the above-described embodiment, if the number of different copy conditions is "1" in step SlO, the process of determining whether or not the copy program can be updated according to the frequency of use of similar copy programs (processes from step S318 to step S29) is performed. ), but this processing step is performed in step S10 → 525-3.
26→S27→S28→S29.

In addition, steps S13, S16.519, and S24 mentioned above
, S25, 326, S29, etc. are displayed using light emitting diodes, but it is preferable to display text using a liquid crystal panel or the like. Also, among the copying conditions stored as a copying program, it is preferable not to store the number of copies.

FIG. 2 is a flowchart showing the overall flow of measuring the usage frequency of a copying program.

A program for measuring the frequency of use of the copy program set for each memory key is written in the ROM 32 mentioned above. In this embodiment, the usage frequency is measured every time the print key 2 is pressed, and the history of the usage frequency of the copy program is recorded in each history area E1B, E19 provided corresponding to each memory key 18, 19, and 20 of the RAM 33. , E2
If the print key 2 is pressed more than 50 times, the usage history data of the copying program is updated in order from the oldest one.

Furthermore, when the copying program is newly updated (step Sll, S20.536 in FIG. 1), all contents of the history area corresponding to the memory key updated at that time are cleared (step S12 in FIG. 1). .321.537).

In this way, each time the print key 2 is pressed, the frequency of use of the copying program is measured.

The following will explain based on a flowchart.

When print key 2 is pressed (step 540), it is determined which memory key 18, 19, or 20 is pressed (steps S41, S42, 543). When the memory key 18 is pressed (step 541), "1" is set in the history area E18, and the history area E19,
E20 is set to "0" (step 544). When the memory key 19 is pressed (step 542), "1" is set in the ffW area E19 and the history area E1 is
B, set "0" to E20 (step 545)
. When the memory key 20 is pressed (step 543), "1" is set in the history area E20, and "0" is set in the history areas EL8 and E19 (step 546).
). If none of the memory keys 18, 19, and 20 are pressed, "0" is set in the history areas E18, E19, and E20.

FIG. 3 shows a control flowchart for calling and setting a stored copying program, and when any memory key 18, 19, or 20 is pressed (step 550).
, lights up display 7.12, L according to the content of the copy program of the pressed memory key (step 551).
. Then, at step S52, the keys 6.8, to, tt, 13.14. 15.
16 is pressed (step 552), key 6.
When 8.10.11.13.14.15.16 is pressed, the pressed copy condition is set and the corresponding display 7.12, L is lit and displayed (step 553), and print key 2 is pressed. wait. If there is no key operation in step S52, the process waits for the print key 2 to be pressed under the copy conditions of the called copy program. When print key 2 is pressed (step 555), a copying operation is executed under the set copying conditions (step 555).

If the copying conditions of the copying program set in each of the memory keys 18, 19, and 20 are approved, the memory key is pressed again without pressing the print key 2 in step S54 (step 556).

When the memory key is pressed again, the display form on the operation display panel 1 returns to the initial display (step 557).

〔Effect of the invention〕

As described above, according to the present invention, a plurality of copy programs having the same copying program and different copying conditions below a predetermined number are not stored, and memory can be used effectively.
