CONSTITUTION:A control part 42 is composed of a CPU 42a, a ROM 42b, a RAM 42c, a timer 42d, etc., and copy sequence is multiple unit controlled based on a control program stored in the ROM 42b, and the same mode information setting frequency, which is set and input from an operation part 41 which is to be a mode setting means at a certain area provided on the RAM 42c to be a mode information recording means, is updated and stored separately by each copy sequence by the program. A counting means retrieves the mode information stored in the mode information recording means and counts the setting frequency by each mode. Thus, the counted maximum setting frequency mode is automatically set as the copy mode by a copy mode automatic setting means.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a copying apparatus having an operation panel for inputting a copying mode necessary for a copying sequence, and in particular, a copying apparatus that automatically selects and sets a copying mode according to the frequency of use. This invention relates to copying devices.

(Prior Art) Conventionally, this type of device has automatic paper selection, which detects the size of a document placed at a predetermined position, automatically selects and feeds paper that matches the document size, and automatically selects and feeds paper that matches the document size. Automatically adjusts the magnification ratio by detecting the original size of the placed original, comparing the original size with the paper size that can be fed, and calculating the magnification ratio that can appropriately transfer the original image to the paper that can be fed. It is configured to be able to execute the processing to be set.

In addition, after an arbitrary operator sets copy in any mode, when a subsequent operator successively executes copy in any mode, the key set by multiple keys placed on the operation panel immediately before In order to reduce the need for resetting operations, devices have also been commercialized that are equipped with a reset key or the like that can automatically return to a predetermined fixed standard mode.

(Problem to be Solved by the Invention) However, in order to execute the automatic paper selection process as described above, it is necessary to use a document size detection mechanism that detects the document size, such as a sensor provided in an automatic document feeder and a paper feeding time. This requires an expensive detection mechanism consisting of measuring means etc., which significantly increases product cost.
There was a problem that reduced the reliability of document size detection.

Additionally, if you manually set a sheet document without using such an automatic document feeder, document size processing will not be performed and the automatic paper selection mechanism will not function effectively, causing the operator to Problems such as image loss may occur depending on the magnification setting and paper size selection.

Furthermore, the standard mode created by pressing the reset key is a standard mode that has been assumed in advance, and has little correlation with the original standard mode that is derived from the environment in which the copying machine is used. There are problems in that the user is forced to set the mode, and a considerable amount of waiting time is required until copying in the desired original standard mode is performed, which significantly impedes copying efficiency.

This invention was made to solve the above problems, and by collecting and registering the copy mode setting history information in the environment where the copying device is used, it is possible to perform the original standard copying in the environment where the device is installed. It is an object of the present invention to provide a copying device that can automatically set a copy mode, paper magnification, etc. corresponding to the mode.

(Means for Solving the Problems) The copying apparatus according to the present invention performs the following operations every time a copying sequence occurs:
mode information storage means for updating and storing the setting frequency of the same mode information set and inputted by the mode setting means for each mode; The apparatus is provided with a counting means for counting the setting frequency and an automatic copying mode setting means for automatically setting the maximum setting frequency mode counted by the counting means.

Further, at this time, a standard copy mode setting means may be provided for automatically setting the maximum setting frequency mode counted by the counting means as the standard copy mode.

Further, at this time, while determining the possibility of setting the mode information of the maximum frequency counted by the counting means, the standard copy mode is set by sequentially lowering the frequency priority from the maximum setting frequency mode counted by the counting means. A copy mode setting control means may be provided.

(Function) In this invention, each time a copying sequence occurs, the setting frequency of the same mode information set and inputted from the mode setting means is updated and registered in the mode information storage means for each mode, and at this time, the counting means is controlled by the mode information storage means. The mode information stored in the mode information is searched to count the setting frequency for each mode, and the automatic copy mode setting means automatically sets the counted maximum setting frequency mode as the copy mode.

Further, the standard copy mode setting means automatically sets the maximum setting frequency mode counted by the counting means as the standard copy mode.

Also, at this time, the standard copy mode setting control means determines the possibility of setting the counted maximum setting frequency mode, and in response to this determination, the frequency priority is sequentially determined from the maximum setting frequency mode counted by the counting means. Lower it to control the standard copy mode.

etc.

When the power switch 2b is turned on, first, the heater in the fixing device 19 is energized and waits (wait time) for the fixing roller to reach a predetermined temperature at which fixing can be performed. When the fixing roller reaches a predetermined temperature, the main drive motor MM is driven for a certain period of time, and the photosensitive drum 11. The fixing device 19 and the like are driven to set the rollers in the fixing device 19 at a uniform temperature (weight release rotation). Thereafter, the main drive motor MM is stopped and the copying is possible (standby state). Here, the main drive motor MM operates between the photosensitive drum 11° and the fixing device 19. The developing units 13a and 13b and various transfer paper conveyance rollers are driven. Then, when a copy command is input from the operation unit 41, a copy sequence is started.

(1) Description of image formation The main drive motor MM rotates in response to a copy command, and the photosensitive drum 11 starts rotating in the direction of the arrow. At the same time, high voltage is supplied from the high voltage unit HVT to the charger 28 and uniformly spread on the photosensitive drum 11. gives an electric charge. Next, the document exposure lamp 2c is turned on, the optical motor 2f is driven, the document placed on the document table is exposed and scanned in the direction of the arrow, and the photosensitive drum 11
Project on top. In this way, an electrostatic latent image is formed on the photosensitive drum 11.

Next, this latent image is developed by the developing unit 13a or 13b, transferred to the cut sheet SH at the transfer charger 15, and separated from the photosensitive drum 11 at the separation charger 19.

Next, the toner remaining on the photosensitive drum 11 is collected by the cleaner device 18, and the static electricity is uniformly removed by the pre-exposure lamp 17, after which the copy cycle is repeated again.

At this time, unnecessary charges outside the image area are erased by a laser unit composed of a semiconductor laser 26, a rotating polygon mirror, and the like.

In addition, the laser unit can erase part of the image by irradiating a laser beam to any location in the image, and can also erase part of the image according to add-on information (for example, page number 9 date, header, footer) input from the operation unit 41. It is possible to irradiate a laser beam and copy over the main part of the cut sheet SH.

One of the developing units 13a and 13b is brought into contact with the photosensitive drum 11 in response to a selection command from the operating section 41.

In this embodiment, the color toner (
For example, red toner) is stored in the developing unit 13b, and black toner is stored in the developing unit 13b, which is approached/retracted from the photosensitive drum 11 by solenoids 14a and 14b. In addition,
Developing unit 13a.

A developing bias voltage is applied to the developing sleeve 13b from the high voltage unit HVT.

In addition, the copying apparatus of this embodiment can perform not only normal single-sided copying but also double-sided copying and multiplex copying, but the cut sheet SH that has passed through the -degree fixing device 19 has a paper resistance value that is higher than that when copying the first side. In response to this change, the conditions of the high voltage applied to the transfer charger 152 and the separation charger 16 are made different between the first side and both sides or the second side during multiple copying. These developing biases or high voltage values for one transfer separation are determined by the high voltage unit 1-H.
Controlled by VT.

The optical system controls the motor control unit 4 according to instructions from the control unit 42.
The reciprocating control is performed by rotating the optical motor 2f forward or reverse via 8.

(2) Control of cut sheet SH Sensor S9 in FIG. Sll detects whether the upper and lower cassettes are out of paper, respectively, and sensors S10 and S12 detect the lifting state of paper feed rollers 3a and 3b.

Moreover, sensor S22. S23 detects the cassette size.

Hereinafter, since the upper and lower stages perform similar operations, the paper feeding operation for the upper stage will be explained. First, when the upper cassette is inserted, the size is read by the sensor S22, the size of the cassette is identified, the out-of-paper indicator of the operation section 41 is turned off, and the cassette size is selected and turned on.

Next, when a copying operation is started in response to a copy command, a middle plate lifting clutch (not shown) is activated to lift the middle plate in the ONL cassette, thereby lifting the cut sheet SH. When the cut sheet SH rises, contacts the paper feed roller 3a, and reaches a predetermined height, the sensor SIO outputs an output and turns the clutch off.
F and drives the paper feed roller 3a to feed the cut sheet SH into the machine.

As described above, the cut sheet SH in the cassette is raised by the intermediate plate raising clutch, and thereafter the raised position is maintained, and the above-mentioned raising operation is not performed at the next copy start.

Further, when the number of cut sheets in the cassette decreases during continuous copying operation and the top surface of the cut sheets SH falls below a predetermined position, the clutch is similarly raised to ONL and a predetermined height.

The cut sheet SH supplied into the machine reaches the sensor S7, and since the registration rollers 12 are stopped, it forms an appropriate loop and stops. Next, in order to align the leading edge of the image formed on the photosensitive drum 11, the registration roller 12 is driven by a timing signal from the optical system, and after aligning the leading edge, the cut sheet SH is transferred onto the photosensitive drum 11 by the transfer charger 15. After the image is transferred onto the cut sheet SH, it is separated from the photosensitive drum 11 by a separation charger 16 and sent to a fixing device 19 by a conveying mechanism.

In the fixing device, the surface of the fixing roller is controlled to a predetermined temperature by a temperature sensor (not shown) placed on the surface of the fixing roller and a heater, and the cut sheet SH is fixed with an image thereon, and then a sensor S4 detects the ejected sheet. The paper is then discharged to the outside of the machine by the paper discharge rollers 23.

Next, in the case of multiple copies, the flapper 21 is operated by a solenoid (
2 minutes before paper feeding and transfer, the fixed cut sheet SH passes through the transport path 22 and is sequentially transported in the transport direction 22a, and is detected by the sensor S5. After the paper is detected, sensor S6. It is detected by S8, etc., and the lateral registration is performed using a solenoid for lateral registration.

Next, the registration rollers 12 are driven by a multiple copy command from the operation unit 41, and the cut sheet SH is sent to the registration roller 12 position.

Thereafter, the paper is ejected to the paper ejection tray 24 in the same manner as described above.

In addition, during double-sided copying, the transfer sheet is ejected halfway through by the paper ejection roller 23 in the same way as in the normal copying operation, but the trailing edge of the cut sheet SH is ejected by the flapper 23.
After passing through, the discharge roller 23 is driven in the reverse direction, and the cut sheet SH is guided by the flapper 21 and introduced into the conveyance path 22.

This reverse rotation drive is performed by a solenoid that controls forward and reverse rotation. The subsequent operations are the same as in the case of multiple copying described above. In this manner, in the case of double-sided copying, the transfer paper is ejected from the machine from the -degree paper discharge roller 23, and the transfer paper is reversed by the reverse rotation of the paper discharge roller 23 and sent in the conveying direction 22a.

Although multiple copying of a single copy and double-sided copying have been described above, in the case of multiple copying of a plurality of copies or double-sided copying, the intermediate tray portion 5 is used. As shown in FIG. 1, the intermediate tray section 5 is provided with an intermediate tray 30 that temporarily stores the cut sheet SH on the conveyance path 31. As shown in FIG. In the case of multiple copying of multiple sheets, the fixed cut sheet SH is partially ejected by the paper ejection roller 23 under the same control as in the case of double-sided copying of the single sheet copy described above, and then the paper ejection roller 23 is driven in the reverse direction. By doing so,
Conveyance path 22 and flapper 32. It is stored in the intermediate tray 30 via the conveyance path 36.

This operation is repeated, and after all of the first side is stored in the intermediate tray 30, the feeding roller 33 is driven for the second side in response to the next copy command, and copying of the second side is executed via the conveyance path 36.

On the other hand, in the case of multiple double-sided copies, the paper passes from the fixing device 19 through the conveyance path 22, 36 by the flapper 21 under the same control as in the case of single-sheet multiple copying, and is stored in the intermediate tray 30.

The subsequent operations are the same as in the case of multiple copying described above, and will therefore be omitted.

Subsequently, the data in the counting area indicated by the pointer (single-sided copy mode area 711, double-sided copy mode area 72, multiple copy mode area 73) is set in area AA of the RAM 42C (4).

Next, the contents of area AA are changed to the contents of limiter (9999
9) Please judge whether the following is true.5), N.

If so, proceed to step (9) onwards, and if YES, compare the contents of area AA with comparison data MAX, and if MAX<A
Determine whether it is A or not (6), if NO, step (9)
Proceed to the following steps, and if YES, set area A to the comparison data MAX.
Set the contents of A7) and update the maximum value. Next, in order to save the maximum value pointer, the contents of the pointer are set in the MAX pointer (8).

Next, determine whether the value of the pointer is the highest address in the counting area9), and if no, set the pointer to "1".
Add (10) and return to step (4).

On the other hand, if the judgment in step (9) is YES, that is, if the processing is executed up to the last data in the counting area, the maximum value in the counting area is stored in the comparison data MAX,
Further, the MAX pointer indicates the address where the maximum value is stored.

Therefore, if the MAX pointer indicates the paper size information 81c for the paper corresponding to the area indicated by the MAX pointer, it is necessary to determine whether or not A4 size paper is set in the main body of the copying machine (11), YES. If so, select the paper indicated by the MAX pointer and display a message 54 on the display 54 as shown in FIG.
Display a (12).

Next, the magnification value corresponding to the area indicated by the MAX pointer is selected and displayed (13).

Next, the copy mode corresponding to the area pointed to by the MAX pointer is selected and displayed (14), and the process ends.

On the other hand, if NO in step (11), the comparison data MAX is set in the limiter (15), and the paper size corresponding to the area indicated by the MAX pointer is displayed as a warning message 54b as shown in FIG. 16), return to step (2).

Then, process steps (1) to (3) and perform RA again.
Search the M42C counting area again.

At this time, since the maximum value is set in the limiter, the second largest value is searched in steps (5) and (6). Then, the standard modes that can be set are sequentially searched for while lowering the priority order one by one.

Note that the automatic selection process described above assumes that the paper to be selected is set in the copying machine, but in reality, the cassette size changes depending on the usage conditions, so if the paper is not set, , select the next most frequently set mode.

In this way, when the copy mode (duplex or multiplex mode) is changed, the paper and magnification corresponding to the standard mode will be automatically selected according to the previous magnification and paper selection status (history). Become.

In the above embodiment, the case was explained in which the number of copies was simply counted in duplex/multiplex mode or for each paper used, but once the copy date and time, mode, magnification, and paper data are
42C, etc., and then execute the counting area update registration process, and then execute the standard mode setting and copying process by the above process. Other embodiments of the present invention will be described below with reference to FIGS. 8 and 9.

FIG. 8 is a schematic diagram illustrating the copy information buffer area secured in the RAM 42C shown in FIG.
Components that are the same as those in the figures are given the same reference numerals.

In this figure, 100 is a buffer area, which is composed of copy information blocks 100-1 to 100-N. Each copy information block 100-1 to 100-N consists of a date and time data area El+ copy number area E2+ copy mode area E3+ magnification area Consists of E4+paper area E5, date and time data area E1. Copy number area E2+
Copy mode area E3 + magnification area E4. Information such as the set date and time, number of copies, copy mode, magnification, paper, etc. is registered in the paper area E5 using a predetermined code.

The contents of the copy information blocks 100-1 to 100-N are sequentially updated each time the copy key 51 is pressed, and the registered data is sequentially discarded starting from the oldest data, and a copy history for a certain period of time from the latest data is maintained.

Next, copy information management processing according to the present invention will be explained with reference to FIG.

FIG. 9 is a flowchart illustrating an example of a copy information management processing procedure according to the present invention. In addition, (1) to (12
) indicates each step. In addition, each step (1) to (1
2) is an example of the procedure corresponding to step (4) of the flowchart shown in FIG. 5(a) described above.

First, the data in the buffer area 1o○ is shifted one block at a time (1). As a result, copy information block 1
Shift the contents of 00-1 to 100-H one block at a time,
The contents of the last copy information block 100-N are moved to the copy information block 100-(N-1), and the copy information block 100-N is made an empty area.

Next, the copy information (
Copy information block 100-N date and time data area El+
Set copy number area E2 + copy mode area E3 + magnification area E4 + paper area E11 (2).

Next, the counting area of the RAM 42C is cleared to all "0" (3), and the pointer for processing data in the buffer area 100 is made to point to the first copy information block 100-1 (4).

Next, copy information block 1 pointed to by the pointer
Contents of date and time data area E of 00-1 to 100-H (
It is determined whether the difference between the date) and the date indicated by the timer 42d is within 10 days5), and if YES, the value A is obtained by multiplying the number of copies stored in the number of copies area E2 by a coefficient "1".
Set AA (6) and add the value AAA to the corresponding area of the counting area of RAM 42C (7).

Next, the pointer points to the final copy information block 100-
It is determined whether N is specified (8), and if YES, the process ends; if No, the pointer is advanced by one block (9), and the process returns to step (5).

On the other hand, if the judgment in step (5) is No, copy information blocks 100-1 to 100 pointed to by the pointer are
- The contents (date) of date and time data area E1 of N are timer 4.
Determine whether the difference from the date indicated by 2d is within 30 days lO). If YES, set the value AAA obtained by multiplying the number of copies stored in the number of copies area E2 by the coefficient ro and 5J. 11), step ( Return to 7).

On the other hand, if the determination in step (10) is NO, a value AAA obtained by multiplying the number of copies stored in the number of copies area E2 by the coefficient ro, 2J is set (12), and the process returns to step (7).

As a result, once the copy data is held in the buffer area 100 and the held copy information is processed, old data will be deleted appropriately according to the size of the buffer area 100, so that the user can use Able to respond to changing circumstances. For example, even if there is a duplex/multiplex mode, magnification, or paper that was used frequently in the past, but is not used much recently, the old data will be deleted, so the Automatic selection processing can be realized.

Also, add date data and reduce weight on older data.
By assigning a higher weight to new items and summing them up, you can quickly respond to subtle changes in usage conditions and greatly improve operability.

Furthermore, in the above embodiment, a case has been described in which the number of copies is counted in the counting area of the RAM 42c, but automatic mode selection processing is executed based on the number of copies (the number of presses of the copy key 51). You may do so.

That is, in step (4) shown in FIG. 5(a), the counting area addition process may be executed every time the copy key 51 is pressed. Then, step (6) shown in FIG.
, (12) and (13), for example, the value AAA of RAM42C is 1.0.5,0 as shown in FIG.
．． Set 2.

As a result, the copy mode and paper magnification are automatically selected according to the number of copies made by the user.

Furthermore, the number of copies may be processed by a predetermined numerical calculation process, such as a square root calculation of the number of copies, in a manner that suppresses the factor of the number of copies.

Therefore, in step (4) shown in FIG. 5(a), square root processing of the number of copies is executed in the counting area addition processing. Then, step (6) shown in FIG.
12) and (13), for example, set the value shown in Fig. 11 to the value AAA of the RAM 42C and the square root of the number of sheets.
, 0.5, 0.2.

Furthermore, in the above embodiment, a case has been described in which automatic selection processing is performed for duplex/multiplex mode, copy magnification, and only paper. By updating and storing the information in the counting area or buffer area 100, it is possible to automate the copy sequence mode setting in response to complex modes.
