It is known to set the copying magnification using a linear potentiometer or the like (for an example, see Japanese Patent Laid-Open No. 52-5529). Problem to be Solved by the Invention In a copying machine that allows the user to set an arbitrary copying magnification, a linear potentiometer or the like is used to set the copying magnification each time a copying operation is performed, and the copying magnification is stored in a memory. Therefore, it is not configured to display the set copy magnification as a numerical value or the like. configured to store a plurality of arbitrary copy magnification data in the memory in advance,
If the desired copy magnification data is read out and the copy magnification can be set as needed, you can find out what kind of copy magnification data is stored in memory just by looking at the operation panel. It is important that the correspondence between the operation for setting the magnification and the copy magnification data is clear, and that it is possible to easily confirm what copy magnification data is selected by operating the operation keys. However, there are no known copying machines in the past that have addressed this problem. The present invention aims to solve the problems of the present invention. Means for Solving the Problems In order to solve the above problems, the present invention has an operation key for inputting the copying magnification of a copying machine and a plurality of storage areas, and each storage area has an operation key for inputting the copy magnification of the copying machine. storage means for storing the input copy magnification; selection operation means for selecting one of the plurality of storage areas; multiple display means for displaying the status;

Embodiment An embodiment of the present invention will be described below with reference to the drawings. Copying Mechanism FIG. 1 shows an example of an electronic copying machine equipped with a magnification setting device according to the present invention. A photoreceptor drum 1 that can be rotated in a counterclockwise direction is arranged approximately in the center of the main body of the copying machine, and around it are a main laser sensor 2, a sub-charger 3, a sub-laser lamp 4, and a main charger 5. , a developing device 6, a transfer charger 7, a copy paper separation charger 8, and a blade type cleaning device 9 are provided. The photoreceptor drum 1 has a photoreceptor layer provided on its surface, and this photoreceptor is sensitized and charged by passing through the eraser lamps 2 and 4 and chargers 3 and 5, and receives image exposure from an optical system 10. . The optical system 10 is installed below the original glass 16 so that the original image can be scanned, and includes a light source (not shown).
It is composed of movable mirrors 11, 12, 13, a lens 14, and a mirror 15. The light source and the movable mirror 11 operate at a circumferential velocity v (equal magnification,
constant regardless of magnification) versus (v/n) (however,
The movable mirrors 12 and 13 are driven by the DC motor M3 so as to move leftward at a speed of (v/2n). In addition,
When changing the copying magnification, it can be seen that the lens 14 moves on the optical axis and the mirror 15 moves and swings, but such a magnification changing device will be described in detail later. On the other hand, paper feed units 20 and 22 are installed on the left side of the copying machine body, each having paper feed rollers 21 (CL2) and 23 (CL3). vs. 26 (CL
1), a conveyor belt 27, a fixing device 28, and a pair of discharge rollers 29. Next, a mechanism for moving lenses, mirrors, etc. for changing magnification will be explained with reference to FIGS. 3 and 4. This magnification change mechanism allows virtually stepless selection of magnification from enlargement to reduction, from enlargement (×1.414) to normal magnification (×1) to reduction (×0.647). The magnification can be selected as appropriate. The magnification changing mechanism generally includes a lens moving mechanism 35, a mirror moving mechanism 40, a mirror swinging mechanism 55, and a stepping motor M4 that drives these. The lens moving mechanism 35 has the lens 14 movably mounted on a guide rail 36 installed parallel to the optical axis, and a drive wire 37 wound around a drive pulley 32 fixed to the output shaft 31 of the stepping motor M4. The drive wire 37 is stretched around rotatable pulleys 38, 38, and the middle part of the drive wire 37 is fixed to the side of the lens 14. Therefore, by rotating the stepping motor M4 forward and backward at a predetermined rotation speed, the drive wire 37 is rotated forward and backward via the drive pulley 32, and the lens 14 is rotated along the guide rail 36 on the optical axis. It moves in the left-right direction in Figure 3 and stops at a position corresponding to the magnification. The mirror moving mechanism 40 has a guide shaft in which the mirror 15 is fixed on the back side to a shaft 43 rotatably supported by a moving body 41, and side pieces 42 of the moving body 41 are set parallel to the optical axis. 45, and a rotatable roller 44 provided at the end of the shaft 43 is placed on an auxiliary guide rail 46. Further, the peripheral surface of a movable drive cam 53 comes into contact with a pin 50 provided on the movable body 41 via a bracket 49, and the movable body 41 is moved toward the cam 53 by a coil spring 48 whose one end is fixed to the pin 47. energized. Output shaft 31 of the stepping motor M4
A gear 33 fixed to is engaged with a gear 52 fixed to one end of a support shaft 51, and the cam 53 is fixed to the other end of the support shaft 51. Therefore, the rotation of the stepping motor M4 is transmitted from the gear 33 to the cam 5 via the gear 52 and the support shaft 51.
3, the movable body 41, that is, the mirror 15 moves back and forth on the optical axis according to the peripheral surface shape of the cam 53,
Correct the optical path length as determined by the change in magnification. That is, the lens 14 and mirror 15 are driven in conjunction with each other by a stepping motor M4 as the magnification is changed, and their positional relationship is as shown in FIG. In the embodiment of the present invention, the rotation amount of the stepping motor M4 can be adjusted continuously in order to perform stepless magnification, but if this is done step by step, a mechanism that selects several steps of magnification will be required. can do. On the other hand, the mirror swinging mechanism 55
The circumferential surface of a swing drive cam 57 fixed to a rotatable support shaft 56 provided in the coil spring 5 is brought into contact with the back surface of the mirror 15, and the mirror 15 is wound around the shaft 43.
The pinion gear 59 fixed to the support shaft 56 is engaged with a rack 60 attached to the main body of the copying machine, and the rack 60 extends parallel to the guide shaft 45. There is. This mirror swinging mechanism 55 corrects the deviation of the exposure point where the optical axis of the light beam reflected by the mirror 15 hits the photoreceptor drum 1 by simply moving the mirror 15 when changing the magnification. At this time, the mirror 15 is also swung so that the optical axis is directed to the same exposure point. That is, when the movable body 41 moves back and forth in accordance with the change in magnification, the pinion gear 59 rolls on the rack 60 and the cam 57 rotates together with the support shaft 56.
The mirror 15 is attached to the shaft 43 according to the circumferential shape of the cam 57.
The exposure point is corrected by swinging around the fulcrum. In this case, the rocking angle of the mirror 15 is positioned such that the optical axis of the light beam reflected by the mirror 15 is directed toward the center of the photoreceptor drum 1 at maximum magnification (at the time of enlargement in this embodiment), and thereby The optical axis is adjusted so that it points to the same exposure point as the exposure point at maximum magnification. Since the slit-shaped image is enlarged and projected, the optical axis at the maximum magnification, where the distortion of the exposed image appears most conspicuously, is incident perpendicularly to the photoreceptor drum 1, thereby reducing the overall deviation of the angle of incidence. This makes distortion of the exposed image less noticeable. Control Device FIG. 5 shows the arrangement of the operation keys on the operation panel of the copying machine. The operation panel 70 includes a print key 7 for starting the copying operation.
Numerical display device 72 capable of displaying 1- and 4-digit numerical values;
Numeric keys 80 to 89 corresponding to numerical values 1, 2, ..., 9, 0, respectively, an interrupt key 90 for specifying interrupt copying, a clear/stop key 91, for specifying copy paper loaded in multiple stages by size. A paper selection key 92, up and down keys 93 and 94 for changing and specifying the copy image density in steps, and a group of keys 95 to 103 related to the copy magnification setting device of the present invention are arranged. First magnification setting key group 95, 96, 97, 98
is arranged for the purpose of arbitrarily setting the magnification, and the key 99 is for switching the first magnification setting mode.
is operated and the control mode of the copying machine is switched to the first magnification setting mode, and when any key is operated, the numerical value inputted by the numeric keypad and displayed on the display device 72 is The copy magnification is stored in the memory corresponding to the operated key. Second magnification setting key group 100, 101, 10
2 and 103 have predetermined copy magnifications set in advance in their corresponding memories, and the copying operation can be performed based on the preset numerical values without having to set numerical values as in the case of the first key group. considered possible to implement. Therefore, the preset copying magnification is, for example, a magnification that is considered to be commonly used for each destination at the factory shipping stage. This will be explained in detail later. In this way, the first group of keys allows the user to arbitrarily set the required copy magnification, and the second group of keys is generally used. For example, if it is a domestic specification, A4 →
They are given different functional roles such that magnifications corresponding to B5, B4→A4, A3→A4, A4→A3, etc. are preset. However, the values preset for the second key group are generally
Alternatively, since the copying magnification is a calculated copying magnification, the actually obtained copy may differ slightly from the copying magnification due to mechanical errors or design errors. For example, even if the same size (x1) is selected, the actual size may be (x1.004) or (x0.996). In such a case, the control mode of the copying machine is switched to the second magnification setting mode by operating the second magnification setting mode switching key 104 shown in FIG. Enter any numerical value using the same operations as 100 to 1 for each key.
03 to obtain the desired copy magnification. Specifically, a numerical value of 1.002 or 0.9988 can be set for the same size key. FIG. 6 shows a control circuit used in the magnification setting device of the present invention, 201 is the first CPU, 202 is the first CPU, and 202 is the first CPU.

It is connected to each drive switching transistor (FIG. 7) of CL3, charger 5, and transfer charger 7. Various data for copying operation control is written in the RAM 203 or shifted from the ROM in the CPU and stored therein.
2, Q3, and Q4, and as will be described in detail later, for example, when the selection key 100 is turned on, the magnification displayed on the display device 72 is written to or read out from the storage unit Q1, and the selection key 101 When turned on, the magnification is written to or read from the storage section Q2. Also, for the selection keys 95 to 98, the storage unit Q
5, Q6, Q7, Q8 are provided in the same manner as above,
For example, when the selection key 95 is turned on, the magnification is written to or read from the storage section Q5. This RAM 203 is backed up by a battery, for example, and its stored contents are retained even if the power is turned off. FIGS. 8 to 15 are flowcharts showing processing procedures for setting magnification and controlling copying operations executed by the first CPU. The present invention will be specifically explained below based on this. FIG. 8 is a flowchart schematically and comprehensively showing the processing procedure in the first CPU. In steps S1 and S2, magnification presetting processing for the storage units Q1 to Q4 is executed, which is mainly done when the machine is assembled or when the machine is shipped from the factory. Details of this process are shown in FIG. In steps S3 and S4, when the copying machine is not in copying operation, each selection key 95 to 98 or 100 is pressed.
A process for associating and setting magnifications A to H to 103 is executed. For details on this process, see Chapter 10.
It is shown in Fig. 12. In step S5, data for controlling the lens position and motor drive speed is transferred to the second CPU 202 in accordance with the magnification set in step S4. When transferring this data, the second CPU
In 02, this is handled by an interrupt. Details of step S5 are shown in FIGS. 13 and 14. In step S6, other processes such as controlling the temperature of the heater of the copying machine and determining the size of the copy paper are collectively shown. In step S7, processing for controlling the copying operation is executed. Details of this process are shown in FIG. Incidentally, FIG. 16 is a time chart showing the operation. Figure 9 shows a group of keys 100 to 1 for setting the second magnification.
This is a flowchart showing details of the initial set rotation for presetting predetermined numerical values in the memories Q1 to Q4 corresponding to 03. Step S1 in Figure 8
The initial switch in , for example, is a switch set in a position in the copying machine that cannot normally be operated, so that it can only be released during assembly at a factory or for service personnel.
The process shown in FIG. 9 is executed only when this switch is operated. The numerical values preset in memories Q1 to Q4 are:
It is determined by the on/off state of the switch associated with the operation of the keys 105, 106, and 107 shown in FIG. 1. Specifically, when assembling the machine,
Alternatively, at the factory shipping stage, etc., an operator turns on and off switches 105 to 107 according to a combination predetermined by the destination, etc., and closes the initial switch. ~A predetermined value is preset in Q4. Steps S501 and S502 are performed by the first CPU.
Switches 105 to 10 stored in 201

Table 1 shows specific examples of brisset values for on/off combinations of switches 105-107.

【table】

[Table] Note that the numerical value "0" does not indicate that a magnification of 0 is set, but indicates that the corresponding key is in an empty state. Processing when the memory is <<0>> will be described later. When setting numerical values as copy magnifications in the memories Q1 to Q8 corresponding to selection keys 95 to 98 and 100 to 103, the processes shown in FIGS. 10 to 12 are executed. In FIG. 10, in steps S101 and S102, when key 99 or 104 is operated to switch to copy magnification setting mode, is magnification setting requested for either the first or second key group? is determined. When key 99 is operated, the first
is the copy magnification setting mode, and flag A is set to “1”.
Set. When the key 104 is operated, a flag B indicating the second copy magnification setting mode is set to "1". When the key 99 or 104 is operated, 1000 is set in steps S103 and S105 in either case.
A process is executed in which the rank flag is set to "1" and the display of the first rank is set to "0". That is, when the control of the copying machine is switched to the magnification setting mode, the numerical display device 7
2 is displayed as “bbb0” (b is blank), and 1000
It enters a standby state to accept input from the digit. If the numeric keypad is operated in this state, the step
The type of key is determined in S107, and only when the "1" key 80 is selected, the process proceeds to step S108 and "1" is displayed in the 1000th place. Note that here, for the sake of convenience in relation to the numerical display device 72, 1000th, 100th, 10th,
I will explain the numerical value input using the expression 1st place,
The numerical value as a magnification is 3 digits after the decimal point and 4 significant figures.
Treated as a decimal number of digits. If the 1000th place flag is "1" and the input numerical value is 0 or 2 to 9, the process advances to step S110 and "0" is displayed at the 1000th place. Next, when the input is "0", step S1 is performed as well as when the input is "1".
Proceed to step 09, set the 1000th flag to "0", set the 100th flag to "1", and wait for input to the 100th digit.
If the input is 2 to 9, the 1000th place flag is set to "0" in step S112, and then the process proceeds to step S115, where the input numerical value is displayed in the 100th place digit. The processing described above when the 1000th place flag is "1" is based on the premise that values in the range of 0.647 to 1.414 are treated as valid copy magnifications, and therefore the 1000th place digit is "1". ” or “0” can be displayed. Also, by doing this,
The key operation when inputting "0" to the 1000th digit is simplified. Note that even if such processing is executed, there may be a case where the numerical value inputted below the 100th place falls outside the range of the above-mentioned effective copy magnification. The processing at this time will be explained in the subroutine section of FIGS. 11 and 12. When the numerical value of the 1000th place digit is input, the 100th place flag becomes "1", and when the numeric keypad is operated in this state, the numerical value corresponding to the operated key is inputted to the 100th place digit, and that value is displayed in step S115. At the same time, in step S116, the 100th place flag is set to "0" and the 10th place flag is set to "1". Below, the input of the 10th place and the 1st place are also performed by operating the numeric keypad. The flowchart of FIG. 11 shows the process of storing the numerical values input and displayed in the process of FIG. 10 in the memory corresponding to the selection key to be operated next. In step S201, it is first determined whether the mode is the first magnification setting mode or the second magnification setting mode. Since step S201 is executed only when either flag A or B is "1", here, for example, only the determination of whether flag A is "1" is executed; 1”, it is the first magnification setting mode, so the step for determining the operation of the first selection key group 95 to 98 is
Proceed to S218 and later, if flag A is not "1",
That is, when flag B is "1", it is the second magnification setting mode, so the second selection key group 100 to 10
The process advances to step S202 and subsequent steps to determine the operation No.3. In the process shown in FIG. 11, in any magnification setting mode, the displayed numerical value is basically stored in the memory corresponding to the operated selection key. However, as described above, at this stage, a value that is not within the range of permissible copying magnifications may be displayed. Therefore, the 11th
In the process shown in the figure, after determining the operation of each key, the subroutine shown in step S203 is executed.
Numerical values outside the permissible range are not stored in memory. The process in step S203 is
Shown in Figure 2. In Figure 12, if the display is not "0",
In step S230, the displayed value is
It is determined whether or not it is smaller than 0.647, and if it is smaller, the display is set to 0.647 in step S231. Also, in step S232, it is determined whether the displayed numerical value is greater than 1.414, and if it is, the process proceeds to step S233.
Set the display to 1.414. Therefore, to explain in relation to FIG. 11, when a predetermined selection key is operated in the magnification setting mode, if the displayed value is outside the allowable range, the display is changed to the allowable limit value, and then the display Stores the current value in the memory corresponding to that key. When the process of storing numerical values in the memory is executed, flag A is set to "0" in the case of the first magnification setting mode, and flag B is set to "0" in the case of the second magnification setting mode, and the process proceeds to step S206. Steps S206 to S208 show the processing when the clear stop key 91 (see FIG. 5) is operated. When the clear stop key 91 is pressed,
In steps S207 and S208, "bbb1" is displayed on the display device 72, and flags A and B are set to "0". That is, clear stop key 9
When 1 is operated, the displayed numerical value is cleared and the magnification setting mode is canceled. Therefore, the numerical value "1" thus displayed is "1" as the standard setting value for the number of copies. 13 and 14 show the processing executed when the second selection key group 100-103 and the selection key group 95-98 are operated, respectively. In FIG. 13, keys 100, 101, 10
When either of 2 and 103 is operated,
Light emitting diode 1 provided corresponding to each key
00a, 101a, 102a and 103a (5th
(see figure) corresponding to the operated key is lit, and then each of the corresponding memories Q1 to Q4
If the content of is not "0", the second CPU 202 uses the numerical value stored in the memory as the magnification data.
The process then proceeds to step S406 in FIG. If the content of the memory corresponding to the operated key is "0", the process similarly advances to step S412. In FIG. 14, when any of the selection keys 95 to 98 is operated, in this case, the corresponding light emitting diode is turned on as described above, and an arbitrary magnification is set, so steps S402, S408,
Corresponding memory Q5 to Q in S415 and S420
The numerical value set to 8 is displayed on the display device 72. For example, this display is performed only when each key is pressed, and when the key is released, the display device 72
is set so that the number of copies set in another storage device is called up and displayed. In the case of this first selection key group as well, if the numerical value stored in the memory corresponding to the operated key is not "0", that numerical value is transferred to the second CPU 202 as magnification data; The process advances to step S412. In steps S412 and S413, if the content of the memory corresponding to the operated key is "0", the magnification value that was selected until the selection key was operated is selected, and the "0" selection state is returned. The flag M shown is set to "1". When the holag M is set to 1 and the operated key is pressed, the process proceeds to step S424, where the flag M is set to "0" at step S425, and at step S426, the "previous" key called at step S412 is set to "0". ``The light emitting diode corresponding to the memory is turned on, and in step S427, the numerical value stored in the memory is transferred to the second CPU 202. That is, even if a key corresponding to a memory having a numerical value of "0" is operated, processing is performed so that the state is the same as if no operation had been performed. The above is an explanation of the setting operation in the magnification setting device of the present invention. As is clear from this description, with this magnification setting device, any copying magnification required by each user can be easily set using the first magnification setting mode, and can be set whenever necessary. While calling up the magnification and confirming the set magnification on the display, the numerical value can be used as control data for the copying machine. Further, according to the second magnification setting mode, mainly from a copy actually obtained by a predetermined copy magnification set in advance,
The effect is achieved that tasks such as reading the error with the numerical copying magnification and correcting the magnification can be performed extremely easily. In response to the numerical value set in this way, the lens 14 outputs the image to the second CPU 202 in accordance with the copying magnification.
The movement of the stepping motor M4 is controlled by the control device 206 based on the output of the stepping motor M4. . Therefore, practically stepless variable magnification can be achieved. Furthermore, the moving speed of the optical system is controlled by the control device 205 based on the output of the second CPU 202 so that it is variable in accordance with the set numerical value.
Many methods have been proposed or provided in the past regarding speed control of the direct current DC motor that is the drive source, and will not be discussed in detail here. In addition, in FIG. 5, the first selection key group 95
~98 and LEDs 95a to 98a indicating that one of these selection key groups 95 to 98 has been selected.
The adjacent panel portion 70a is configured with a whiteboard that can be written on and erased with a prescribed writing instrument, a removable adhesive sticker, or a panel that can be attached and detached by magnetic force, and a copying magnification value set arbitrarily by the user can be set. Memorize and display by writing etc. Furthermore, in addition to the copy magnification value, it is also possible to record the purpose of the copy magnification value, such as characters such as "Paper-A4", thereby further improving operability. The panel portion 70a may have a concave or convex level difference with other panel portions as necessary. Copying Operation FIG. 15 is a flowchart showing an example of controlling the copying operation of the copying machine. Regarding this, the first

In block 11, it is determined that the timer TA has expired and the paper feed clutch is turned off. In block 12, it is determined that the timer T-B has ended, and the scan motor M3 is turned on to start the scan operation. In block 13, when the timing signal is output during the scan operation, the timing roller clutch CL3 is turned on and the timer T-

It is transported in synchronization with the image above. In block 14, it is determined that the timer T-C has expired, and the charging, scan motor, and timing roller clutch are turned off. Note that the timer TC may be set variably depending on the size of the copy sheet used. In block 15, when the optical system returns to the home position due to the return operation and the home position switch is turned on, the developing motor M2 and the transfer charger 1 are turned on.

Note that the timers T-A to T-D, etc. explained in the flowchart and time chart above are MCs that are executed at times specified by internal timers.
This digital timer is programmed to count up to "1" in one routine of 50 processes, and the time-up time is stored as numerical data. Effects of the Invention As explained above, according to the present invention, there is a one-to-one correspondence between the copy magnification storage area in the memory selected by the operation of the operating means and the display means, and furthermore, the area adjacent to the display means is Since there is a memory member that can be assigned by the user, it is possible to know what kind of copy magnification data is stored in the memory just by looking at the operation panel. The correspondence between the operation for setting the magnification and the copy magnification data is clear, and the copy magnification data selected by the operation of the operation keys can be easily confirmed, and if it is different from the desired one. There is no risk of copying at the copy magnification.
