Abstract

PURPOSE:To obtain automatically a copy of a suitable zoom magnification desired by an operator, by driving little by little a lens position adjusting mechanism, and a speed adjusting mechanism of an optical system, etc., whenever a copy operation of one sheet portion is ended, and repeating continuously a copy operation of a prescribed sheet number portion. CONSTITUTION:A zoom continuous mode key 2, and a varied magnification setting key 3 are provided on the upper left part of an operating board 1 and under said key, respectively, and also, on its lower part, a copy sheet number setting key 4 is provided. A ten key 5 inputs a varied magnification and a copy sheet number. Also, keys 6a, 6b are an up-key and a down-key for designating whether a zoom magnification is made to ascend or descend, in case the zoom magnification is varied little by little from a state of a designated zoom magnification. A variation of the zoom magnification is executed to match a varied magnification which has been set while an optical system, etc. are executing a return operation, and a loss caused by the time required for a variation of the zoom magnification can be made as small as possible.

Description

[Detailed Description of the Invention] "Field of Application of the Invention" First of all, it is necessary to improve a copying machine that has a zoom function, especially when copying several sheets in a continuous manner instead of changing the zoom magnification sequentially. This invention relates to an automatic continuous zoom copying apparatus that performs 14 operations.

"Background of the Invention" Normally, when copying using a copying device with a zoom function, the reduction or enlargement ratio (zoom magnification) between the dimensions of the original and the dimensions of the required copy is adjusted to The operation of calculating the magnification by calculating the ratio is performed, and the zoom magnification obtained by the calculation is set to 1 and the copying operation is performed. However, the zoom magnification obtained through such calculation may not always be the optimum magnification desired by the operator. This is because it is often impossible to intuitively judge whether or not the image is appropriate until you actually see the copied image.
This is because there are sometimes design problems that require fine adjustment of the magnification.

Therefore, in such a case, first make a copy by specifying an appropriate zoom magnification and make that copy.

After visually determining whether the copy is larger or smaller than the desired copy, change the zoom magnification appropriately and perform the copying operation again.
It is often determined whether the second copy obtained in this way has the desired size, and then repeats the process of changing the zoom magnification again and performing the copying operation.

In this case, copies will be made in increments of several percentage points, and after each copy operation is completed, copy '! J2
You have to wait for the machine to stop, reset the zoom magnification, and then start copying. This has the disadvantage that it takes a long time, and during that time, it is necessary to wait until the operation of the copying machine is finished, resulting in poor work efficiency.

``Object of the Invention'' Therefore, the object of the present invention is to automate the work of changing the zoom magnification in small increments as described above and copying an appropriate number of sheets, thereby improving work efficiency. be.

"Structure of the Invention" In order to achieve the above object, the present invention adopts five means. In a copying apparatus that has an optical system constant speed adjustment mechanism that adjusts the speed and allows setting of zoom magnification, - Every time the copying operation of the ashes is completed, the uR mechanism and the optical system constant speed adjustment between the lens positions are performed. This is an automatic continuous zoom copying apparatus in which a mechanism is driven in small increments to continuously repeat a copying operation for a predetermined number of sheets.

Among the above components, the zoom lens includes both a zoom lens type and a type that zooms by moving a short focus lens. The optical system constant speed adjustment mechanism is composed of, for example, a DC motor or the like as a drive source for the optical system.

``Example'' Next, examples embodying the present invention will be described with reference to the attached drawings to provide an understanding of the present invention. here the first

FIG. 2 is a plan view showing an example of how various devices are arranged on the operation panel of the copying machine.

In addition, the following example is only an example of embodying the present invention,
It is not intended to limit the technical scope of the present invention.

First, an overview of the hardware configuration of an automatic continuous zoom copying apparatus according to an embodiment of the present invention will be explained with reference to FIG.

The CPU in the figure is the core of the computer that is connected to the copying machine main body control circuit, pulse motor control circuit, and DC motor control circuit via an interface circuit, and processes automatic continuous zoom copying work according to the control program built in the ROM. It is the central processing unit that makes up the system.

The pulse motor control circuit includes a circuit for controlling a pulse motor for adjusting the position of the zoom lens, and D
The C motor control circuit controls the movement of the optical system and the original fi% level.
This circuit is for controlling the rotational speed of the C motor, and by appropriately controlling the pulse motor control circuit and the DC motor control circuit, it is possible to adjust the zoom magnification of the copy image relative to the original.

A RAM as a storage device is connected to the CPU, and the input side board of the CPU has continuous zoom mode keys 2. Change magnification set key 3. One copy safe key 4. Up/down key 6M, 6k.

Various keys such as a numeric keypad 59 for instructing processing contents and other keys (not shown) are connected.

It goes without saying that various display devices shown in FIG. 3 are connected to the output side interface circuit.

Next, an example of the arrangement of keys and display devices on the operation panel will be explained with reference to FIG.

In Fig. 3, the first part is a control panel, on the upper left side of which is provided a zoom continuous mode key 2, below that is a variable magnification set key 3, and further below that is a copy number safe key 4. There is. 5 is a numeric keypad for inputting the change magnification and the number of copies. Further, [ia, 5b are up keys and down keys for specifying whether to increase or decrease the zoom magnification when changing the zoom magnification in small increments from a specified zoom magnification state. Further, 7 is a print key for starting the copying process, 8 is a zoom magnification indicator consisting of an LED etc. for displaying the specified zoom magnification, and 9 is a print key for displaying the specified number of copies. The sheet number display and numeral 10 are change rate call keys for calling up the specified small change magnification again and displaying it on the display 8.

Next, the working procedure of automatic continuous zoom copying according to this embodiment will be explained with reference to FIGS. 1 and 3 and FIG. 2, which is a flowchart showing the working procedure.

In FIG. 2, St, S2, . . . indicate processing procedure (step) numbers.

When the program starts, it is first determined at Sl whether the zoom continuous mode key 2 is turned on or not. In this embodiment, the zoom continuous mode key 2 is of the type that when pressed once, it enters the center state, and when pressed again, returns to the reset state.

Therefore, next at 82, the zoom continuous mode key 2 is pressed.
Determine whether or not it is set. If it is determined that the zoom continuous mode flag is set, the continuous zoom mode flag specified in the CPU is turned on (S3), and the continuous zoom mode flag is turned on in S4. Determine whether or not there is. If the process proceeds from S3 to 84, the continuous zoom continuous mode flag is of course on, so the process proceeds to S5.

If the zoom continuous mode key 2 is not in the ON state in step S1, the process jumps to S4 and it is determined whether the zoom continuous mode flag is already in the ON state. If it is determined in S2 that the continuous zoom mode key 2 is not in the cent state, the continuous zoom mode flag is turned off in S6. This is the case if the operator has not selected the continuous mode zoom copying process of the present invention.

After turning off the zoom continuous mode flag at 36 as described above, the process proceeds to S4.

As described above, if it is determined that the zoom continuous mode flag is on in step S4, it is determined that the operator desires continuous mode zoom copying processing, so the change magnification cent key 3 is turned on in step S5. Determine whether it is.

Here, if change magnification cent key 3 is on, S
At step 7, the operator uses the numeric keypad 5 to input the change magnification. This change magnification is, for example, 0.5%, 1.0%
, 2.0%, etc. When the change magnification is input in this way, in 88, the CPU sets a change magnification flag to indicate that the change magnification has been input manually, and
Proceed to 9.

If the change magnification set key 3 is not on in S5, the process bypasses S7 and S8 and jumps to S9. S9
In this step, it is determined whether the copy number safe key 4 is turned on. If the operator has already pressed the number of copies set key at this point, the process proceeds to SIO, where the operator inputs the number of copies using the numeric keypad 5, and then the number of copies flag is set (Sll ), the process proceeds to S12. If it is determined in S9 that the copy number setting key 4 is not yet in the on state, the process bypasses the SIO and Sll steps and jumps to S12.

At 512, it is determined whether the print key 7 for performing copy processing has been pressed by the operator. If the print key 7 has not been pressed yet, the process returns to step S1. Therefore, if the operator has not yet set the change magnification and the number of copies, the operator can set the change magnification and the number of copies by repeating steps 31-312 before pressing the print key 7. will be given the opportunity to do so.

However, if the operator does not want to set the change magnification or the number of copies by himself and wants to leave it to the machine to set the change magnification or the number of copies,
The operator presses the print key 7, omitting the numerical cent steps in S7 and SIO, and proceeds to steps 315 and below.

In step S4, if it is determined that the zoom continuous mode flag is not on yet, the change magnification flag and the number of copies flag are cleared L (313, 51
4), the process advances to 812;

Regardless of whether or not the change magnification and copy magnification are set, if the print key 7 is turned on in S12, the zoom continuous mode flag is turned on again in S15. Determine whether or not there is. If the zoom continuous mode flag is not on, this indicates that the operator has selected the normal copy mode, so the process jumps to 322.

If it is determined in S15 that the zoom continuous mode flag is on, first in 316 it is determined whether the one-copy number flag is set. If the number of copies flag has already been set, SIO, S
Since the operator has already set the desired number of copies in S17. The process bypasses S18 and advances to 319.

If it is determined in S16 that the number of copies flag has not been set yet, the number of copies flag is set in S17, and a fixed number of copies set in the software is automatically set ( 51B). The number of copies at this time is 3.

It is set to a value of about 5 sheets.

Subsequently, in 319, it is determined whether the change magnification flag is set. If YES here, the change magnification desired by the operator has already been set in S7 and S8, so the process advances to 322. If it is determined in step 519 that the change magnification flag has not been set yet, it means that the operator has forgotten to set the change magnification or wants it to be set automatically. At 320, a change rate flag is set, and at 521, a constant change rate set in software is set.

The change magnification at this time is, for example, a value such as 1% or 2%.

In this way, either the changing magnification and the number of copies are set according to the operator's will, or the changing magnification and the number of copies are automatically set by the software, or the continuous zoom mode copying process is not performed. However, there may be cases where the number of copies or change magnification is not set at all. In either case, the next operation is to start a copy operation at 522.

If be < 323, 1 is added to the value of the copy number memory set in the RAM area, and the process waits until the optical system or document table moves to the return operation in S24.

In this embodiment, the zoom magnification is changed at 326 in accordance with the change magnification set while the optical system is performing a return operation, and the loss due to the time required to change the zoom magnification is minimized. I have to.

That is, in S24, when the return of the optical system is started, the process proceeds to S25, and it is determined whether the zoom continuous copy mode flag is turned on or not. YES here
In this case, a signal is sent to the pulse motor control circuit (Figure 1) to drive the pulse motor by an amount commensurate with the change magnification, and a signal is also sent to the DC motor control circuit to control the optical system or document table. Set the rotation speed of the DC motor that determines the movement speed.

Since it takes some time to move the lens by driving the pulse motor as described above, it is desirable, as described above, that the optical system performs the process 526 during the return as shown at 824.

If the zoom continuous copy mode flag is not on in S25, this indicates that the operator desires normal copy processing, so the copying operation of the first bone in S27 is completed without changing the change magnification in S26. The process moves on to the step of determining whether or not.

In S27, it is determined that the ashes copying operation has been completed.
If the number of set copies is not reached yet, the process proceeds to 328 to determine whether the value in the number of copies register has reached the initially set number of copies.
The process returns to step S22 and repeats the processes from S22 to 828. If it is determined in 828 that the number of copies has already reached the set value, the copying end process is performed in S29.

If the operator desires automatic continuous zoom copy processing, the number of set copies in step 328 may be the number of copies of the three or five copies automatically set by the software, or the number of copies set by the operator himself in S10. If the number of copies is set and the operator does not want automatic continuous zoom processing but wants normal copy processing,
This refers to the number of copies per original set by the operator.

"Effects of the Invention" As described above, the present invention provides a lens position adjustment mechanism that adjusts the position of the zoom lens and an optical system constant speed adjustment mechanism that adjusts the moving speed of the optical system and document table. In a copying apparatus that allows setting of zoom magnification, - constant velocity modulation of the lens position adjustment mechanism and optical system every time a bone collection operation is completed! I! Since this automatic continuous zoom copying device is characterized by continuously repeating the copying operation for a predetermined number of sheets by driving the mechanism in small increments, it is possible to automatically obtain copies with an appropriate zoom magnification desired by the operator. This greatly contributes to improving work efficiency, since there is no need to copy each sheet one by one and check whether the desired copy has been obtained as in the conventional method.
