Description

DETAILED DESCRIPTION OF THE INVENTION 1. Field of the Invention The present invention relates to image processing apparatuses such as printers and copying machines, and more particularly to an image processing apparatus capable of storing and recalling operation modes.

2. Prior Art For example, in recent years, copying machines have been enriched with functions, and various copy modes (copy conditions) can be set to meet the various demands of operators.

Additionally, it is equipped with multiple paper feed trays and uses a removable paper feed cassette so that several types of recording paper of different sizes can be loaded at any time.

Although these functions have become more multifunctional, the operator's operations have also become more complicated, resulting in the inconvenience of having to operate many operation key switches to set the required operation mode each time a copy is to be made.

Therefore, a copying apparatus has been proposed which is equipped with a storage device for storing a copy mode and which can be called up by a simple key switch operation.

In this case, if frequently used copy modes are stored in the storage device of the copying apparatus, copy mode setting becomes easy.

Incidentally, frequently used copy modes vary depending on the operator or the object to be copied (original document, etc.). Therefore, it is necessary to freely write the copy mode to the storage device of the copying device.

However, since a conventional copying apparatus equipped with this type of writable storage device does not have a means for inhibiting writing, it is not possible to protect the copy mode written in the storage device. Therefore, if you call it without knowing that the copy mode stored in the storage device has been updated to the copy mode written later,
There was a problem in that copies with completely different recording paper sizes, reduction/enlargement ratios, etc. were created.

(Objective of the Invention) An object of the present invention is to prevent operational errors in an image processing apparatus capable of storing and recalling operation modes.

■Structure of the Invention In order to achieve the above object, the present invention provides an input means for inputting image processing data; a storage means for storing image processing data; and an instruction to prohibit writing of image processing data to the storage means. write-protection instruction means;
When there is a write prohibition instruction from the write prohibition instruction means, write prohibition setting means for setting write prohibition of image processing data to the storage means; write instruction means for instructing writing of image processing data to the storage means; write control for writing image processing data inputted from the input means into the storage means in response to a write instruction from the write instruction means in a state where the write prohibition setting means does not set write prohibition of the image processing data to the storage means; means; readout instruction means for instructing readout of the image processing data from the storage means; readout control means for reading out the image processing data from the storage means in response to a readout instruction from the readout instruction means; for instructing the start of image processing. Image processing start instruction means: When image processing data is input from the input means, an image processing mode is set according to the input image processing data, and when the image processing data is read by the readout control means, the readout image is set. Mode setting means for setting an image processing mode according to processing data; and an image processing start instruction from an image processing start instruction means.

An image processing control means for starting image processing in an image processing mode set by the mode setting means;

According to this, the image processing data from the input means is written into the storage means in response to a write instruction from the write instruction means;
Since it is possible to set write prohibition to the storage means by the write prohibition instruction from the write prohibition instruction means, for example, if image processing data of a frequently used operation mode is written to the storage means and then write prohibition is set, the written data can be protected. can be protected.

Other objects and features of the invention will become apparent from the following description of an embodiment with reference to one drawing.

FIG. 1 shows an outline of the mechanism of a copying apparatus according to an embodiment of the present invention. This will be explained with reference to FIG.

1 is the contact glass on which the original is placed.

2 is an automatic document feeder that doubles as a pressure plate! ! (hereinafter referred to as ADF device).

The document set may be set directly on the contact glass 1 with the pressure plate 2 open, or may be set on the document table of the ADF device 2 (on the right side of the ADF device 2 in FIG. 1). In the latter case, when the ADF device 2 detects that there is a document on the document tray, the copy start instruction input becomes an ADF start instruction, and after feeding the document and setting it at a predetermined position on the contact glass 1, the ADF device 2 Device 2 issues a copy start instruction. The operation mode of this ADF device 2 is 2.
The first is the ADF mode, where the manual command to start copying → loading the original on the document tray → copying → ejecting the original and loading the next original → etc. continues until all the originals on the document tray are exhausted. Yes, and the second is inputting a copy start instruction → loading the M document on the document placement table → copying → ejecting the original → waiting for inputting a copy start instruction.
This is ADF mode.

In both cases, when the original is set directly on the contact glass 1 and when the ADF device is used, the original is pressed down by a white belt stretched over the contact surface of the ADF device [2 that contacts the contact glass 1]. and is brought into close contact with the contact glass 1.

An optical scanning system including an exposure lamp 3, a first mirror 4, a second mirror 5, a third mirror 6, a condenser lens 7, a fourth mirror 8, etc. is provided below the contact glass 1. Light reflected from the original by exposure lamp 3 is guided to photosensitive drum 9 by this optical system. The copying apparatus of this embodiment is of a document fixed type, and includes a first carriage (not shown) on which an exposure lamp 3, a first mirror 4, etc. are mounted, and a second carriage (not shown) on which a second mirror 5, a third mirror 6, etc. are mounted. Two carriages (not shown) are driven at a speed ratio of 2:1, and the original is scanned while keeping the optical path length constant. This document scanning is performed in synchronization with the photoreceptor drum 9 (clockwise in FIG. 1) rotating at a constant speed, and in the case of full-size copying, the movement speed of the surface of the photoreceptor drum 9 is ``ωE c
m / s e c ] (r: radius of photoreceptor drum 9 [cm], ω: rotational angular velocity of photoreceptor drum 9 [rad/
5ecl) and the document scanning speed v[cm/sea] are set to be equal. In the case of enlarged copying, if the magnification rate is M, the condensing lens 7 moves to the left on the optical axis in FIG. The scanning speed v [em,/sec] is.

It is set to 1/M of the moving speed rω [cm/sec] of the surface of the photoreceptor drum 9. In the case of reduced copying, if the reduction ratio is 1/m, the condenser lens 7 moves to the right on the optical axis in FIG. 1 to reduce the projected image on the photosensitive drum 9 to 1/m. Therefore, the document scanning speed V[cm/5ecl is set to m times the moving speed rω[cm/5ecl] of the surface of the photosensitive drum 9.

Around the photoreceptor drum 9 are a charging charger 10° and a developing unit 11. Transfer charger 122 Separation charger 13
．． A cleaning unit 14 and the like are arranged.

There are a total of 5 paper feed trays, and the top is the first paper feed tray.

They are called a second stage paper feed stand, a third stage paper feed stand, a fourth stage paper feed stand, and a fifth stage paper feed stand. A removable paper feed cassette 15, 18, 21°24.27 is attached to each paper feed tray.

This copying apparatus can feed up to A3 size recording paper in the longitudinal direction (hereinafter referred to as "horizontal feeding"; on the other hand, paper feeding in the transverse direction is referred to as "vertical feeding"). Therefore, for A3 horizontal # paper, lJ, for A4 vertical feeding, for A4 horizontal feeding, for A5 vertical feeding, for A5 horizontal feeding, for B4 horizontal feeding, for B5 vertical feeding, for B5 horizontal feeding. , 11 for B6 vertical paper feeding, B6 horizontal paper feeding and universal paper feeding (free size)
Various paper cassettes are available. These paper feed cassettes are equipped with a detection mark indicating the type (size of paper accommodated), and is read by a paper size detection sensor (57) provided on each paper feed table when the cassette is installed. Specifically, the size detection sensor (57) is a photo interrupter, and when a cassette is attached, a light-shielding filler with a detection mark enters and reads the type of paper feed cassette that is attached by transmitting light or blocking light (the detection mark is used as a magnet). , may be read by turning on/off a magnetically sensitive reed switch). The detection mark codes are shown in Table 1 below.

However, in Table 1, "0" indicates light transmission (no light blocking filler), and "1" indicates light blocking (with light blocking filler).

Table 1 When the first stage paper feed tray is selected, the recording paper stored in the paper feed cassette 15 is fed by the paper feed rollers 16 and the feed rollers 17 toward the registration rollers 30.
When the second stage paper feed tray is selected, the recording paper stored in the paper feed cassette 18 is fed out toward the registration rollers 30 by the paper feed rollers 19 and feed rollers 20.
When the third stage paper feed tray is selected, the recording paper stored in the paper feed cassette 21 is fed out toward the registration rollers 30 by the paper feed rollers 22 and feed rollers 23.48, and the recording paper is fed to the fourth stage paper feed tray. When is selected, the recording paper stored in the paper feed cassette 24 is fed out toward the registration roller 30 by the paper feed roller 25 and feed rollers 26, 47° 48, and the fifth stage paper feed table is selected. , paper feed roller 28 and feed rollers 29, 45, 46, 47
．． 48 feeds the recording paper stored in the paper feed cassette 27 toward the registration rollers 30.

The registration roller 30 feeds the recording paper fed out at a predetermined timing to the photosensitive drum 9 (sheet feeding).

On the downstream side of the photosensitive drum 9, a conveyor belt 31. A fixing unit 32 and the like are provided.

The conveyance path of the recording paper after leaving the fixing unit is divided into two paths. One is a paper discharge conveyance path that discharges paper to a paper discharge tray 35 via a paper discharge roller 34 when the switching claw 33 is lowered (the state shown in FIG. 1), and the other is a This is a paper refeed conveyance path that leads to the intermediate tray 36 via feed rollers 39 and 40 when the switching claw 33 is raised (rotated in the direction of the arrow in FIG. 1).

In the double-sided copy mode, when copying the front side, a switching solenoid (not shown) is energized, the switching pawl is rotated, the paper re-feeding path is selected, and the copy side is recorded on the intermediate tray 36 with the copy side facing up. Save paper. From the paper refeed transport path to intermediate tray 3
The recording paper stored in 6 (with a copy on the front side) is
The right-shifting roller 37, which rotates in the direction of the arrow, shifts the intermediate tray 36 to the right side in FIG.
2, 43, 44, and 48, it is fed out toward the registration rollers 30. Thereafter, the registration roller 30 sends this recording paper to the photosensitive drum 9 at a predetermined timing, but at this time, the side with the copy is facing down and the back side is the transfer surface.

Note that the intermediate tray 36 has an opening/closing lid on the left side in FIG. 1, and when canceling five-sided copying, the recording paper on which the front side has been copied can be taken out from there.

An overview of the copy process will be explained. The copy process can be divided into a start cycle, a copy cycle and an end cycle.

After operating the operation board and inputting predetermined copy conditions, the operator sets the document and inputs a copy start instruction.

When using the ADF device 2, this instruction becomes an ADF start instruction, and the ADF device 2 issues a copy start instruction after loading the document on the document table and setting it at a predetermined position on the contact glass l.

In response to a copy start instruction, a start cycle is first executed. The start cycle is performed for the purpose of stabilizing the mechanical drive system and unifying the initial exposure conditions. A drive source such as a main motor is energized, and then the photosensitive drum 9 is rotated and the photosensitive drum 9 is rotated. Surface cleaning is performed. In this.

A grounded conductive brush and a cleaning blade provided in the cleaning unit 14 wipe away toner, carrier, and the like that have adhered while the apparatus is stopped, and the static electricity is further removed by a static elimination lamp (not shown).

Upon completion of cleaning and neutralization of the photosensitive surface (end of start cycle), a copy cycle is executed.

In this process, charging of the photosensitive surface → electrostatic latent image formation → development →
Transfer is performed in the order of fixing. First, charger 1
0, the photosensitive surface of the photosensitive drum 3 is uniformly charged to a high positive potential, and an eraser (not shown) erases unnecessary areas according to the paper size.

The optical system is energized at a predetermined timing so that the exposure of the leading edge of the document matches the leading edge erase end position.

The document is irradiated by the exposure lamp 3 and scanned by the first and second carriages.

The reflected light of the original is transmitted to the first mirror 4. 2nd mirror 5 and 3rd mirror
When reflected by the mirror 6 and condensed by the lens 7, it is reflected by the fourth mirror 8 and formed into an image on the photosensitive surface of the photosensitive drum 9.

When the photosensitive surface of the photosensitive drum 9, which is uniformly charged to a high positive potential, is irradiated with reflected light from the original, the surface charge is removed according to the strength of the reflected light from the original due to the photoelectric groove phenomenon, and static electricity is generated. A latent image is formed.

Since this electrostatic latent image is formed negatively, the developing device 1
1, negatively charged toner adheres and becomes visible (
Developed: positive image).

Before starting exposure, each paper feed cassette 15, 18, 21°24
．． The recording paper fed out from 27 or the intermediate tray 36 to the registration rollers 30 is stopped once in contact with the registration rollers 30, and is directed toward the photoreceptor drum 9 at a predetermined timing according to the rotation of the photoreceptor drum 9. will be sent.

When the recording paper passes directly above the transfer charger 12 to which a predetermined voltage is applied, it comes into contact with the toner image formed on the photosensitive surface of the photosensitive drum 9, and the toner image is transferred.

That is, the registration roller 30 has a feeding speed V p [c
The recording paper is fed out at a speed of m/sec].

After the toner image has been transferred, the photosensitive surface passes through the cleaning unit 14 and is cleaned and neutralized to remove residual toner and carrier in the same manner as described above.

The recording paper onto which the toner image has been transferred is separated from the photosensitive surface of the photosensitive drum 9 by a separation charger 13 and a separation claw (not shown), and then transferred to a fixing unit 32 by a conveyor belt 31.
sent to. The fixing unit 32 is a pair of rollers with a built-in heater, and the toner image on the recording paper is fixed here.

Here, for copying in single-sided copy mode (outside double-sided copy mode) or back-side copying in double-sided copy mode, a switching drive solenoid (not shown) for the switching pawl 33 is used.
Since the switching claw 33 is not energized, the switching claw 33 is lowered, and the recording paper that has left the fixing unit 32 is transferred to the paper ejection roller 34.
The paper is ejected to the paper ejection tray 35 via. When copying on the down side in double-sided copy mode, the switching drive solenoid of the switching pawl 33 is energized, so the switching pawl 33 rotates in the direction of the arrow and rises, causing the fixing unit 32 to be removed. The recorded recording paper is guided to the intermediate tray 36 via feed rollers 39 and 40.

After repeating the above copy cycle for the set number of sheets, in the end cycle, the photosensitive drum 9 is further
Rotates to clean and neutralize the photosensitive surface. This end cycle is performed to maintain stability and protect the photosensitive surface of the photosensitive drum 9, so the processing content is the same as the start cycle, and if a copy start instruction is given while the end cycle is being executed, the start cycle is omitted. and execute from the copy cycle.

FIG. 2 is a block diagram schematically showing the control system of the copying apparatus shown in FIG. 1. This will be explained with reference to FIG.

In Fig. 2, overline indicates that the terminal is L active, and VCC indicates a constant voltage or a terminal to which constant voltage Vcc is applied.The control system is controlled by the main microcomputer (hereinafter referred to as , MCPU) 50 and three sub-microcomputers (hereinafter referred to as 5 ICPU, 52 CPU, and 53 CPU).

The MCPU 50 centrally controls this control system, and its pass line includes a read-only memory (ROM).
52, a read/write memory (RAM) 53, an I10 device 56, an s ICP'U 62, and the like are connected. Decoder 51 and latch circuit 61 are bus drivers.

The ROM 52 mainly stores control programs necessary for controlling the copying apparatus.

In the RAM 53, each processing parameter (copy condition) necessary for each copy process is sequentially written and read out as necessary.In addition, this RAM 53 has a non-volatile memory area backed up by a battery, Several sets of copy conditions are stored in association with the numbers.

54 is a battery backup circuit for backing up the RAM 53, and 55 is a power supply voltage monitoring circuit. The power supply monitoring circuit 55 receives a reset signal (
L level) and constant voltage Vcc (e.g. +5v)
When the voltage becomes lower than a predetermined voltage (for example, 4.5V), a reset signal (L level) is generated. This reset signal is
PU50゜5ICPU62S2CPU63,53CPU
.

I10 device 56 and battery backup circuit 5
It is applied to the reset terminal of No. 4.

When a reset signal is applied to the battery backup circuit 54, transistors T r 1 and T r 2 are put into a cut-off state. As a result, the constant voltage input terminal (Vec) of the RAM 53 and the chip select input terminal GE
The voltage of battery BT will be applied to. The voltage of battery BT is set lower than constant voltage Vcc (for example, 3
v) Therefore, writing to and reading from the RAM 53 becomes impossible.

When the power supply voltage is unstable, the power supply voltage monitoring circuit 55 may malfunction, so the battery backup circuit 54
A Zener diode ZDI is inserted into the reset input terminal of the . This Zener diode ZDI prevents the battery backup circuit 54 from malfunctioning due to a reset signal that fluctuates below the Zener potential (for example, 4V).

When the reset signal becomes H level after a predetermined period of time has passed after the power is turned on or after the constant voltage Vcc is restored, the base current flows to the transistor T r 1 via the Zener diode ZD1, so the T r 1 is turned on. This also turns on the transistor Tr2. therefore,
A constant voltage V is input to the constant voltage input terminal (Vcc) of the RAM53.
Since cc is applied and the L level is applied to the chip select input terminal GE, writing to and reading from the RAM 53 becomes possible.

That is, this reset signal prevents the memory contents from being destroyed due to the influence of noise when the power is turned on, which tends to occur in battery-backed memories and the like.

When the L level is applied to the chip select input terminal GE of the RAM 53, the RD and W of the MCPU 50
Writing to and reading from the nonvolatile memory area of the RAM 53 is executed based on the R times signal.

The MCPU 50 monitors the voltage of the battery BT of the battery backup circuit 54 using the analog output (ANO), and displays a warning (Fig. 3 Bat) when the voltage falls below a predetermined voltage (for example, 2.8 V).

A size detection sensor 57, its decoder driver 58, a motor and solenoid driver 59, a sensor unit 60, and the like are connected to the I10 device 56.

The decoder driver 58, in response to a reading instruction from the MCPU 50, sets the reading of the detection mark on the paper feed cassette from the first stage paper feed tray to the fifth stage paper feed tray depending on luck.

The size detection sensor 57 includes four sets of five photointerrupters for reading the same bits of each paper feed table connected in parallel,
5 for detecting the presence or absence of recording paper on each paper feed tray connected in parallel
It consists of one set of two reflective photosensors. That is, when the decoder driver 58 is set to read the first stage paper feed tray, four photo interrupters for reading each bit are used to detect the detection mark ( (see Table 1), and.

A reflective photo sensor reads the presence or absence of recording paper in the paper feed cassette; if the decoder driver 58 is set to read the second paper feed tray, four photo interrupters for reading each bit read the second paper feed tray. The detection mark on the paper feed cassette mounted on the tier 3 paper feed tray and the presence or absence of recording paper in that paper cassette are read using a reflective photo sensor; The detection mark on the paper cassette and the presence or absence of recording paper.

The detection mark and the presence or absence of recording paper are read on the paper feed cassette mounted on the fourth paper feed tray, and the detection mark and the presence or absence of recording paper on the paper feed cassette mounted on the fifth paper feed tray are read. In this reading, for each paper feed tray, the MCPU 50 indicates the size of the recording paper (see Figure 1) using the LSB to 3rd bit, indicates the paper feed tray number using the 4th to 6th bits, and uses the MSB to indicate the recording paper size (see Figure 1). 8-bit size data indicating the presence or absence of recording paper is created and written into the size table of the RAM 53 (normal read/write area).

FIG. 4a shows an example of the size data of the second stage paper feed tray in the size table. FIG. 4a shows that a paper feed cassette for A4 horizontal paper feed is attached to the second stage paper feed tray, and there is recording paper.

Initialize etc.

In S2, the protection circuits of each component of the device are scanned and if an abnormality is found (S3), abnormality processing such as setting the corresponding display on the abnormality indicator 100 is performed (S4), and the process continues in S2-S until the abnormality is removed. 3-84-32-...I can't get out of the loop.

In the process of reading the status of each part, in addition to scanning the protection circuit, the size detection sensor 57 and its decoder driver 58 read the detection marks on the paper feed cassettes installed on the paper feed trays of each stage, and detect whether there is recording paper or not. Perform reading.

The size table described above is created and the display on the paper size display 110 is set.

In S5, the standard mode of the copying device is set.

In this ninth step, set the number of sheets to 1 (set counter ← 1
); Automatic density adjustment mode setting ("Auto" flag set); Density center (density register ← 4); 1st paper feed tray setting (paper feed tray counter ← 1); Variable magnification equal to magnification (variable magnification register ←
100); ADF mode setting ("ADF" flag set); sort mode setting ("sort" flag set); other flags reset;

In S6, a power relay (not shown) is turned on to supply power to each part, and the presence or absence of an abnormality is checked again in the same manner as in S2. If there is no abnormality (S7, S8), a standby mode is set.

In the standby mode, a key operation loop of the operation board is formed, returning to 87 after each round of the loop, and processing of reading the status of each part (scanning of the protection circuit and...

(reads the detection mark on the paper feed cassette installed on each stage paper feed table and reads the presence or absence of recording paper).

In S16, the key operation input on the operation board is read by the driver 1 (64) and buffer 1 (65) described above.

See Figure 5c.

When the operation of the write key 7o is read in the input reading in S16, it is detected in 5101.

If the rKEYJ flag is present in 5102, this indicates that another key or write key 7o has already been used and is being continued, so the process returns to S7.

If this flag does not exist, it means that the rising edge of the key operation of the write key 7o has been read, and the rKE'YJ flag is set in step 5103. Therefore, even if the write key 70 is continuously pressed from now on.

Since the rKEYJ flag is present when passing through 8102 next time, the process returns to S7 without performing the following processing (key operation reading is canceled).

The presence or absence of the "write" flag is checked in 5104, and if this flag is not present, it is an instruction to set the write mode, so 51
In step 05, the presence or absence of the "call" flag is checked, and if the call mode is being set, it is to be canceled (step 5106), and in step 5107, the "write" flag is set and the write indicator lamp 71 is turned on.

In other words, write mode and call mode are not set at the same time.

In step 5104, check whether there is a "write" flag, and if this flag is present, it is an instruction to cancel the write mode, so in step 510
8 to reset the "write" flag and turn on the write indicator lamp 71.
Turn off the light.

At 5109, the program register (which stores the designated number of the program mode) is cleared and the process returns to S7.

When the operation of the call key 72 is read in the input reading in S16, it is detected in 5110.

Check the presence or absence of the rKEYJ flag with 5ill, and if it reads the rise of the key operation of the call key 72, it is 511.
2 sets the rKEYJ flag.

5113 checks whether there is a "call" flag, and if this flag is not present, it is an instruction to set the call mode, so 51
In step 14, the presence or absence of the "write" flag is checked, and if the write mode is being set, it is canceled (step 5115), and in step 5116, the "call" flag is set, and the call indicator lamp 73 is turned on.

In other words, call mode and write mode are not set at the same time.

5113 checks whether the "call" flag is present, and if this flag is present, it is an instruction to cancel the call mode, so 511
7 to reset the "call" flag and turn on the call indicator lamp 73.
6 Clear the program register in S109 and return to S7.

When the operation of the protect key 74 is read in the input reading in S16, it is detected in 5118.

Check whether the rKEYJ flag is present in 5119, and if the rising edge of the key operation of the protect key 74 is read, 5 is detected.
At 120, the rKEYJ flag is set.

At step 5121, the presence or absence of the "protect" flag is checked, and if this flag is not present, the "protect" flag is set at step 5122, since this is an instruction to set the protect mode.
The protect indicator lamp 75 is turned on.

The presence or absence of the "protect" flag is checked in step 312+, and if this flag is present, this is an instruction to cancel the protect mode, so in step 5123 the "protect" flag is reset and the protect display lamp 75 is turned off.

At 5109, the program register is cleared and the process returns to S7.

See Figure 5d.

When the operation of the interrupt key 89 is read in the input reading at 516, it is detected at 5124.

5125 checks whether the rKEYJ flag is present, and if the rising edge of the interrupt key 89 key operation is read, 512
6 sets the rKEYJ flag.

The presence or absence of the "interrupt" flag is checked in 5127, and if this flag is not present, it is an instruction to set the interrupt mode, so 51
28, set the "interrupt" flag and turn on the interrupt indicator lamp 90.
lights up and saves the copy conditions being set to the interrupt register.

5127 checks whether there is an "interrupt" flag, and if this flag is present, it is an instruction to cancel the interrupt mode, so 512
9 to reset the "interrupt" flag and turn on the interrupt display lamp 90.
is turned off and the copy condition saved in the 1 interrupt register is called.

After this, the process returns to S7 and enters an input waiting loop.

When the operation of the numeric keypad 91 is read in the input reading in S16, it is detected in 5130.

5131 checks whether the rKEYJ flag is present or not, and if it reads the rising edge of a key operation on the numeric keypad 91, 513
2 sets the rKEYJ flag.

At step 5133, the numerical value corresponding to the operated key is stored in the numerical value register.

At 5134, 5135, and 5136, check the presence or absence of the "write" flag, "call j flag," and "protect" flag, and if all of these flags are not present, it is not 1 in program mode, but an instruction to set the number of sheets. , 5137, the presence or absence of the "shift" flag is checked. If there is no "shift" flag, this is the first input for setting the number of sheets to be set, and the value of the numerical register is checked in step 5138. Since the number of sheets to be set is set between 1 and 99 sheets, it is meaningless even if the value 0 is input at the beginning, and is canceled.

If the value of the numerical register is 1 to 9, a "shift" flag is set in step 5139, and the numerical value of the numerical register is set in the 1 digit of the set register in step 5141, and displayed on the set number display 94.

Next, when the numeric keypad 91 is operated to set the number of sheets to be set, there is a "shift" flag, which changes from 5137 to 5140.
, shift the set register by one high-order digit, and set it to 514.
1, the value in the numerical register is displayed in the 1's digit of the set register on the set number display 94.

At 5134, 5135, and 5136, the presence or absence of the "write" flag, "call" flag, and "protect" flag is checked, and if any one of these flags exists, it means that the number is specified in the program mode, and the number register is set at 5142. You can learn the value of. Since the number designation in the program mode is made with a numerical value from 1 to 5, if the value in the numerical register is not within this range, it is canceled.

If the value of the numerical register is between 1 and 5, the value of the numerical register is set in the program register at step 5143.

At 5144, address data corresponding to the value of the program register (ie, designated number) is read from the address table stored in the nonvolatile memory area of the RAM 53. Here, the address table will be explained.

FIG. 4b shows an example of address data corresponding to number 1 in the address table. The address table consists of five pieces of address data corresponding to numbers 1 to 5, respectively, configured in the same way.

The address data specifies the start address of the area (in the non-volatile memory area of the RAM 53) in which the copy condition is stored in association with number 1 using the LSB to the second bit; the third to fifth bits indicate the number; The 6th bit indicates whether the copy condition associated with that number has been written (1: written, 0: not written); MSB indicates the protection of the copy condition written in association with that number. Specified or not specified [
1: Protected (update not possible), 0: Updatable without protection)]. In the example of Figure 4b, number 1
The copy condition is associated with the start address E100.
It is written in an area starting with (hexadecimal), indicating that the copy condition is not specified as protect.

Referring again to Figure 5d.

At step 5144, address data corresponding to the value of the program register is read from the address table, and at step 5145, the MSB of the read address data is checked. This is 1
If so, the data (copy condition) written in association with the specified number, that is, the value of the program register, is protected (cannot be updated), so
For 8146, the data protection indicator lamp 7 of that number
Turn on 9°81.83.85 or 87 and turn off the other data protection indicator lamps.

If the MSB of the address data read with 5145 is 0, it can be updated without specifying protection), so 5
147, data protection display lamps 79, 81, 8
3. Turn off all lights of 85 and 87.

At step 5148, the sixth bit of the read address data is checked. If this is 1, the data (copy condition) has been written in association with the specified number, that is, the value of the program register, so in the 5149, the data write indicator lamp 78, 80, 82 of that number .84 or 86 is lit, and the other data writing indicator lamps are turned off.

The 6th bit of the address data read in 5148 is 0.
If so, there is no data writing, so 5150
Now, all data write indicator lamps 78, 80, 82, 84 and 86 are turned off.

After this, the process returns to S7.

See Figure 5e.

When the # key 92 is operated during input reading in S16,
5151 to detect.

5152 to check whether the rKEYJ flag is present or not, and press # key 9
If the rising edge of key operation No. 2 is read, the rKEYJ flag is set in step 5153.

The value of the program register is checked in step 5154, and if no value is stored there (20), this key operation is canceled because the number has not been specified yet.

When a number is specified and the number is stored in the program register, the address data corresponding to the number is read out from the address data in the RAM 53 in step 5155.

At 3156, the presence or absence of the "write" flag is checked, and if this flag is present, write mode processing is performed.

The following is the processing in the V-inclusive mode.

5157 resets the "write" flag, 5158a
Then, check the MSB of the read address data.

If the MSB is 1, the data written in association with that number (copy condition) is protected, so the data cannot be updated in write mode. In this case, the program mode is canceled in S158b. Here, if there is a "protect" flag, it is reset and the indicator lamp (write indicator lamp 71.
Protect indicator lamp 75. Data writing indicator lamp 78
, 80°82.84 or 86. Alternatively, the data protection display lamps 79, 81, 83, 85, or 87 (hereinafter, program mode display lamps) are turned off.

If the MSB is not 1, data (copy conditions) will be written in association with the specified number in the following process, so in step 5159, the sixth bit of the read address data is set to 1.

5160 checks whether the "protect" flag is present or not,
If this flag exists, 8161 resets it and 51
At step 62, the MSB of the read address data is set to 1. If there is no "protect" flag, steps 5161 and 5162 are not performed. That is, in the combined mode of write mode and protect mode, data (copy conditions) is written in association with a designated number, and data protection is designated.

In step 5163, each indicator lamp in the program mode is turned off.

5164, the value of the size register; the value of the scaling register; lag, rxo, 82j flag.

Write the presence or absence of rxo, 7iJ flag, "double-sided" flag, rADFJ flag, and "sort" flag.

In step 5165, since the contents of the address data corresponding to the specified number have been changed, the changed address data is written to the address table. This completes the write mode processing, so the process returns to 87.

At 8156, the presence or absence of the "write" flag is checked. If this flag is not present, the presence or absence of the "call" flag is checked at 8166. If this flag is present, the call mode processing is performed. The following is the process in call mode.

At 8167, the "call" flag is reset, at 3168,
Check the 6th bit of the read address data. If this is not 1, data (
Since no copy conditions (copy conditions) have been written, the call mode is meaningless, and the program mode is canceled at 5158b.

If the sixth bit of the address data is 1, it means that the data (copy condition) has been written in association with the specified number, so in step 5169, the presence or absence of the "protect" flag is checked. If this flag exists, it is reset in 8170, and in 5171, the 7th flag of the read address data is reset.
Reset the bit to 0 and write the changed address data to the address table.

5170 and 51 without the "protect" flag
71 is not performed, that is, in the combined mode of the call mode and the protect mode, the protection designation of the data (copy condition) written in association with the designated number is canceled.

In step 5172, each indicator lamp in the program mode is turned off.

5173, the value of the size register; the value of the scaling register; rxl, 15J flag from the data storage area (in the non-volatile memory area) of the RAM 53 at the address specified by the read address data.

rXo, 82J flag, rxO, 7N flag.

“Double-sided J flag, rADFJ flag and “Sort”
Read the presence/absence of the flag and set the register and flag respectively.

In step 5174, it is checked whether or not the "back" flag is present in the copy condition being set. That is, this corresponds to, for example, a case where the call mode is set by interrupt processing while copying the back side in the single-sided mode, and the "back" flag is activated. In that case, this flag is reset at 5175.

In the flow shown in FIG. 5f, copy conditions are set based on the data read in step 5173.

At 8176, the variable magnification is displayed on the variable magnification display 114 based on the value of the variable magnification register.

5177, the display may be different from the one before reading, so double-sided display lamp 97. Front display lamp 98. Back indicator lamp 99. Xl, 1'5 indicator lamp l 16. X
o, 82 display lamp 118°xo, 71 display lamp 12
0. ADF indicator lamp 122.5 ADF indicator lamp 12
3. The sort indicator lamp 125 and the stack indicator lamp 126 are all turned off.

5178 checks whether the "double-sided" flag is present or not.

If this flag is present, the double-sided display lamp 97 and the front display lamp 98 are turned on in step 5179.

At 5180, the presence or absence of the rxl, 15J flag is checked, and if this flag is present, the Xi, 15 display lamp 116 is turned on at 5181.

In 5182, check whether the "x0.82" flag is present or not,
If this flag is present, the Xo, 82 display lamp 118 is turned on in step 5183.

In 8184, check the presence or absence of rXo and 71J flags,
If this flag is present, the Xo, 71 display lamp 120 is turned on in step 5185.

At 5186, it is checked whether the "rADF" flag is present or not. If this flag is present, the ADF display lamp 122 is lit at 8188, and if this flag is not present, the 5ADF display lamp 123 is lit at 5187.

5189 checks whether the "sort" flag is present or not.

If this flag exists, the sort display lamp 12 will be displayed at 5191.
If this flag does not exist, the stack display lamp 126 is turned on at 5190.

At 5192, the value of the paper feed table counter is cleared, and at 5193, the paper feed table counter is amplified by one count.

The size table for R, A, M 53 stores the paper size data based on the paper feed power cent detection mark attached to each paper feed tray and reading whether or not recorded paper is read. The paper size data corresponding to the value of the paper tray counter is read, and the value indicating the recording paper size is loaded into the register SIZ.

5195 compares the value of the size register, that is, the recording paper size specified in the call mode, with the value of the register SIZ, and if they are not equal, the paper feed table counter is incremented by one count and the comparison is repeated. . While repeating this comparison, if the value of the size register becomes equal to the value of register SIZ, the recording paper specified in the call mode is stored in the paper feed tray of the stage indicated by the value of the paper feed tray counter at that time. In step 5202, the frame in the column corresponding to the paper feed tray of this stage on the paper size display 110 is lit to display the set paper feed tray ("Confirm"). (no flags).

Since there are a total of five paper feed trays, if the value of the paper feed tray counter reaches 5 in 8196, this means that the paper feed cassette that accommodates the recording paper specified in the call mode is not installed in this device. At 5197, the paper feed table counter is set to 1.

At step 5198, the "confirmation" flag is set and the confirmation display lamp 77 is turned on.

5199, the display corresponding to the value of the size register on the specified paper size display 76 (A3.A4.A5°B4.B5
or B6 display, and vertical or horizontal display, or
Universal (*) display] lights up.

In step 5202, the frame in the column corresponding to the first stage paper feed tray is lit to indicate that the first stage paper feed tray is set.

In other words, in this case, the paper feed cassette that stores the recording paper specified in the call mode is not installed in this device, so the recording paper is fed from the paper cassette installed in the first stage paper feed tray. This may result in copy errors. Therefore, the confirmation indicator lamp 77 lights up and the operator is asked to confirm the cassette! ! > and displays the designated recording paper size on the designated paper size display 76.

As a result, when the operator attaches a paper feed cassette containing recording paper of the size displayed on the designated paper size display 76 to any paper feed tray and operates the # key 92 again, the detected in 5151,
This time, since there is no "call j flag and "protect" flag (already reset), 5152-S153-S1
54-S192, the size table is searched in the same manner as above to search for a paper feed tray into which a paper feed cassette whose size data matches the designated paper size is to be installed.

When this is detected in 5195, the process proceeds to 5200.

Since there is a "confirmation" flag, this flag is reset in step 5201, the confirmation display lamp is turned off, and the display on the specified paper size display 76 is turned off.

The above is the call mode processing.

5156-3166-S203-3204--, that is, when the # key 92 is operated when there is no "write" flag or "call" flag and there is a "protect" flag, the "protect" is selected at 5204. The flag is reset, and in 5205, the 6th bit and MSB of the address data read in 5155 are reset to 0.
Then store this number again in the original area of the address table.

In 8206, RAM 5 specified by this address data
In step 5207, the data stored in the data storage area (in the non-volatile memory area) of step 3 is cleared, and in step 5207, each display lamp in the program mode is turned off.

In other words, only in the protect mode, data (copy conditions) stored in association with a designated number are cleared.

Referring again to Figure 50.

When the C key 93 is operated while reading the input of SI6,
Detected at 5208.

Check whether the rKEYJ flag is present with 5209, and press C key 9.
If the rising edge of key operation 3 is read, the rKEYJ flag is set at 5210.

5211, set the value of the set register to 1,
The r shift flag indicating the carry of the set register is reset, and the set number of sheets (1 sheet) is displayed on the set sheet number display 94.

See Figure 5g.

When the input is read in S16, if the double-sided key 96 is operated, it is detected in step 5212.

5213 checks whether the "KEY" flag is present, and if the rising edge of the key operation of the double-sided key 96 is read, 5214
Set the rKEYJ flag with .

5215 checks whether there is a "duplex" flag, and if this flag is not present, it is an instruction to set the duplex mode, so 32
Set the "double-sided" flag in step 16, and turn on the double-sided display lamp 97.
Then, the display lamp 98 is turned on.

5215 checks whether there is a "duplex" flag, and if this flag is present, it is an instruction to cancel the duplex mode, so 521
7 to reset the "double-sided" flag and double-sided display lamp 97
Then, the front display lamp 98 is turned off.

If you have already finished copying the front side in 1-duplex mode, the back side copy mode is set, so 5
218a, if there is a back J flag, 5218b
After resetting this and turning off the back display lamp 99, the process returns to S7.

If the dark key 101 is operated during input reading in S16, it is detected in step 5219.

5220 checks whether the rKEYJ flag is present or not, and if it reads the rise of the key operation of dark key 101, it is 5.
At step 221, the rKEYJ flag and the "dark" flag for detecting continuous operation (pressing) of the dark key 101 are set. Since the operation of this dark key 101 indicates the operator's intention to perform manual density adjustment, the "auto" flag is reset in step 5222, and the auto display lamp 104 is turned off. There are seven stages, and these stages correspond to the values of the density register. That is, the smaller the value of the density register, the darker the stage, and the value 1 represents the darkest first stage density. Therefore, if the value of the density register is 1 in 5224,
Since a darker level cannot be set, the operation of the dark key 101 is canceled.

If the value of the concentration register is not 1, the concentration register is decremented in 5225, and in 8226, the manual concentration display 105 displays the value corresponding to this concentration register value, that is, one 0 mark is set on the manual concentration display 105. Shift to the left and turn on.

Thereafter, a time delay of dtl (for example, 0.3 seconds) is performed at 5227, and the process returns to 37.

Therefore, if the dark key 101 is continuously operated, it will be detected again at 5219, and this time it will be detected at 5220.
The rKEYJ flag is set, but since the "dark" flag is set, the process proceeds from 5223 to 5224, and if the value of the density register is not 1, the density is set one step darker at dt1 time intervals, and the manual density is set. Display 105
The 0 mark is shifted to the left one by one and turned on (S225°5226, 5227).

As will be described later, the "dark" flag is set to dark key 10.
It is reset when the operation (pressing down) of step 1 is stopped.

When the input is read in S16, if the light key 102 is operated, it is detected in step 5228.

Check the presence or absence of the rKEYJ flag with 5229, and if it reads the rise of the key operation of the light key 102, 5
At 230, the rKEYJ flag and a "write" flag for detecting continued operation (pressing) of the write key 102 are set. Since this operation of the light key 102 indicates the operator's intention to perform manual density adjustment, the "auto" flag is reset in step 5231, and the auto display lamp 104 is turned off.

The values in the density register correspond to the density levels, with the value 7 indicating the seventh level density, which is the lightest. If the value of the density register is 7 in step 5233, it is not possible to set a lighter level than that, so the operation of the light key 102 is canceled.

If the value of the concentration register is not 7, the concentration register is incremented by 1 at 5234, and the manual concentration display 105 displays the value corresponding to the value of this concentration register at 8226;
In other words, manual #a changes the 0 mark on the degree display 105 to 1
It shifts to the right and lights up.

After this, a time delay of dtt (for example, 0.3 seconds) is performed at 5227, and the process returns to 87.

Therefore, if the light key 102 is continuously operated, it is detected again at 5228, and this time it is detected at 5229.
The rKEYJ flag is set, but since the "write" flag is set, proceed from 5232 to 5233,
If the value of the concentration register is not 7, the concentration is set one step lighter in sequence at dt1 time intervals, and the manual concentration display 10 is set.
Shift the 0 mark of 5 one by one to the right and turn it on (S225
゜5226. 5227).

As will be described later, the "write" flag is set to the light key 10.
It is reset when the operation (pressing down) of step 2 is stopped.

When the input is read at 316, if the auto key 103 is operated, it is detected at 5235.

5236 checks whether the rKEYJ flag is present or not, and if it reads the rise of the key operation of the auto key 103, it is 5.
237 sets the rKEYJ flag.

Since the auto key 103 is an alternate switch,
The presence or absence of the "auto" flag is checked at 5238. If this flag is not present, the instruction is to set the automatic density adjustment mode, so the "auto" flag is set at 5239, the auto display lamp 104 is lit, and the manual density display is started. vessel 10
Turn off the display of 5.

The presence or absence of the "auto" flag is checked at 8238, and if this flag is present, this is an instruction to cancel the automatic density adjustment mode, so the "auto" flag is reset at 5240 and the auto display lamp 104 is turned off.

The display on the manual concentration display 105 is turned on.

See Figure 5h.

If the paper key 109 is operated during input reading in S16, it is detected in step 5241.

5242 checks whether the rKEYJ flag is present or not, and if it reads the rise of the paper key 109 key operation, 5242 is used.
At 43, the rKEYj flag is sent.

There are a total of 5 paper feed trays, and the value of the paper feed tray counter corresponds to this. Therefore, in 5244, check the value of the paper feed tray counter by 1, and if this value is 5, then use 5245 to check the value of the paper feed tray counter. Clear the value.

At 8246, the value of the paper feed tray counter is incremented by one, and the outer frame of the column corresponding to the value of the paper feed tray counter on the paper size display 110 is lit to display the set paper feed tray.

In other words, each time the paper key 109 is operated, the value of the paper feed tray counter is amplified by one count, the paper feed tray of the next lower level is updated, and the column indicating the paper feed tray of the paper size display 110 is set. The outer frame is shifted down by one position and turned on, but the value of the paper feed tray counter is 5, that is, 1, the lowest 5th stage paper feed tray is set, and the outer frame of this column on the display 110 is lit. Then, in the next operation of the paper key 109, the setting returns to the uppermost first stage paper feed tray, and the outer frame of this column on the 1 display 110 is lit.

Since the copy conditions change by operating the paper key 109,
In step 5247, the size table specified by the value of the paper feed counter is referred to, and a value indicating the recording paper size for which paper feed is to be set is stored in the size register.

At 5248, the presence or absence of the "confirmation" flag is checked. This flag is set in 8198 in the above-mentioned call mode when a paper feed cassette containing recording paper of the size specified by the copy condition called by specifying a number is not installed on any of the paper feed trays. However, paper key 1
The operation of 09 means that the operator has finished checking the paper cassette, so this "confirmation" is performed in 5249.
The flag is reset, the confirmation display lamp 77 (cassette confirmation!) is turned off, and the display on the designated paper size display 76 is turned off.

When the input is read at 316, if the reduction key 111 is operated, it is detected at 5250.

In S251, check whether the rKEYJ flag is present or not, and if the rising edge of the key operation of the reduction key 111 is read, it is 52.
52 sets the "rKEY" flag.

As mentioned above, this copying device has a linear ratio of 0.5 times (50%
) to 2.0 times (200%), and this scaling ratio corresponds to the value of the scaling register. In other words,
The value in the scaling register is equal to the scaling factor as a percentage. Therefore, if the value of the scaling register is 50, a smaller scaling ratio cannot be set, and in that case, the operation of the reduction key 111 is canceled in step 5254.

If the value of the scaling register is not 50, the scaling register is decremented by 1 in step 5255, and the scaling ratio corresponding to the value of this scaling register is displayed on the scaling ratio display 114.

If there is no "reduction" flag for detecting continuous operation (pressing) of the reduction key 111 in 5256, the reduction key 1
Since this is the first processing for 11 operations, d at 5257
Perform a time delay of tl (eg 0.3 seconds) and set the "shrink" flag.

The standard magnification reset of 8258 is performed by setting the standard magnification flag (rxl, ], 5J) when the standard magnification (described next) is set before the reduction key 111 is operated.

rxo, 82J, rxo, 7N flags) and check the flags that are set and the corresponding display lamps (Xl, 15
Display lamp 116. Turn off the X0.82 indicator lamp 118 or the Xo,71 indicator lamp 120).

If the reduction key 111 is continuously operated, it is detected again by 5250, and this time, rKEYJ of 5251 is detected.
The flag is set, but "Since the reduction flag is set, proceed from 5253 to 5254, and if the value of the scaling register is not 50, the scaling register is decremented by 1 at 5255, and the value of this scaling register is The magnification ratio corresponding to is displayed on the magnification ratio display 114.

In the next step 8256, since the "reduction" flag is set, the process proceeds to 8259 and a time delay of dt2 (for example, 0.1 seconds) is performed.

That is, when the value of the scaling register exceeds 50 and the reduction key 111 is continuously operated (pressed), the scaling ratio is first updated to a value smaller by 1% at dt1 time intervals, and from then on, The scaling factor is updated to a value smaller by 1% at dt2 time intervals.

If the enlargement key 112 is operated during input reading in S16, it is detected at 8260.

5261 checks whether the rKEYJ flag is present, and if it reads the rise of the key operation of the enlarged key 112, 52
62 sets the rKEYJ flag.

The value of the scaling register is equal to the value of the scaling ratio expressed as a percentage, so if the value of the scaling register is 200, it is not possible to set a larger scaling ratio, so in that case, it is enlarged with 8264. Cancels the operation of key 112.

If the value of the scaling register is not 200, the scaling register is incremented by 1 in step 8265, and the scaling ratio corresponding to the value of this scaling register is displayed on the scaling ratio display 114.

If there is no "enlargement" flag for detecting continuous operation (pressing) of the enlargement key 112 in step 8266.

Since this is the first process for the expansion key 112 operation, 8
267, a time delay of dtl (for example, 0.3 seconds) is performed and the "enlarge" flag is set.

At 8268, the above-mentioned standard magnification change reset is performed, and the process returns to S7.

If the enlargement key 112 is continuously operated, it is detected again by 8260, and this time, rKEYJ of 5261 is detected.
The flag is set, but since the "enlargement" flag is set, the process proceeds from 5263 to 5264, and if the value of the scaling register is not 200, the scaling register is incremented by 1 at 5265, and the value of this scaling register is The scaling factor corresponding to the value is displayed on the scaling factor display 114.

In the next step 8266, since the "enlargement" flag is set, the process proceeds to 8269, and a time delay of dt2 (for example, 0.1 seconds) is performed.

In other words, if the value of the scaling register is less than 200, if the enlargement key 112 is continuously operated (pressed), the scaling ratio is first updated to a value 1% larger at dt1 time intervals, and then updates the scaling factor successively to a value 1% larger at dt2 time intervals.

Therefore, for example, dtl is 0.3 seconds and dt2 is 3.0 seconds.
When the setting is 1 second, when the scaling factor is quickly brought close to the target value, the scaling factor can be set at high speed by continuously operating (pressing) the scaling down key 111 or the expanding key 112. Furthermore, when making fine adjustments as the target value approaches, the "reduction" flag or "enlargement" flag can be set using the reduction key 1. ], 1 or enlarge key 11
Since the setting value is reset when key operations 2 are stopped, the set value can be changed by 1% by repeating these key operations within 0.3 seconds.

See FIG. 51.

If the 1/1 size key 113 is operated during input reading in S16, it is detected in step 5270.

Check whether the rKEYJ flag is present or not with 5271, and if it reads the rise of the key operation of the same size key 113, 52
72 sets the rKEYJ flag.

At step 5273, the value of the variable magnification register is checked, and if this is 100, the variable magnification has already been set to equal magnification, so this key operation is canceled.

5273, if the value of the scaling register is not 100, 52
At 74, perform the standard magnification reset and set the value 1 to the magnification register.
Store 00.

Thereafter, in step 5294, the value of the scaling register, that is, 100, is displayed on the scaling ratio display 114.

When the input is read in S16, if the Xl, 15 key 115 is operated, it is detected in step 8276.

5277, check whether the rKEYJ flag is present or not, xi, 1
If you want to read the rise of key operation of 5 key 115,
5278 sets the rKEYJ flag.

At step 5279, the presence or absence of the rXl, 154 flag is checked, and if this flag is present, the operation of the new Xi, 15 key 115 is canceled because the standard magnification of 1.15x has already been set.

If this flag is a certain number, reset the standard scaling at 5280, store the value 115 in the scaling register at 5281,
Set the rXl, 15J flag and turn on the xi, 15 display lamp 116.

Thereafter, in step 5294, the value of the scaling register, that is, 115, is displayed on the scaling ratio display 114.

Upon reading the input at 516, if the Xo and 82 keys 117 are operated, it is detected at 5282.

Check whether rKEYJ flag is present or not on 5283, Xo,
If the rising edge of the key operation of the 82 key 117 is read, the rKEYJ flag is set in 5284.

Check the presence or absence of rXo and 82J flags on 5285,
If this flag is present, the standard magnification of 0.82x has already been set, so the new operation of the Xo and 82 keys 117 is canceled.

If this flag does not exist, the standard scaling is reset at 8286, the value 82 is stored in the scaling register at 5287, and r
Set the xO, 82J flag and turn on the Xo, 82 display lamp 118.

Thereafter, in step 5294, the value of the scaling register, that is, 82, is displayed on the scaling ratio display 114.

If the Xo and 71 keys 119 are operated during input reading in S16, it is detected in step 5288.

Check the presence or absence of the rKEYJ flag on 5289, Xo, 7
If you want to read the rise of key operation of 1 key 119,
5290, sets the "rKE.Y" flag.

5291, the presence or absence of the "Xα, 71" flag is checked, and if this flag is present, the new operation of the Xo, 71 key 119 is canceled because the standard magnification of 0.71 times has already been set.

If this flag does not exist, the standard scaling is reset in 5292, the value 71 is stored in the scaling register in 5293, and the rx
o, 7 N flag is set and Xo, 71 display lamp 120 is lit.

Thereafter, in step 5294, the value of the scaling register, that is, 71, is displayed on the scaling ratio display 114.

In this way, the magnification ratio is set corresponding to the value of the magnification register, so if you press the reduction key 111 to change the magnification ratio set in the standard magnification
Alternatively, fine adjustment can be made using the enlargement key 112.

See Figure 5j.

By reading the input of S16, ADF/5ADF key 121
If there is an operation, it is detected in 5295.

Check whether the rKEYJ flag is present on 5296, and use ADF.
/5 If the rising edge of the key operation of the ADF key 121 is read, the rKEYJ flag is set in 5297.

5298 checks whether the rADF, + flag is present, and if this flag is not present, it is an instruction to set ADF mode, so 5299 sets the rADFJ flag, and A, D
The F display lamp 122 is turned on and the 5ADF display lamp 123 is turned off.

Check the presence or absence of the rADFJ flag in 5298, and if this flag is present, it is an instruction to set the 5ADF mode, so
At step 5300, the rADFJ flag is reset, the ADF display lamp 22 is turned off, and the 5ADF display lamp 123 is turned on.

When reading input at S16, sort/stack key 124
If there is an operation, it is detected in 5301.

At step 5302, the presence or absence of the rKEYj flag is checked, and if the rising edge of the key operation of the 5 sort/stack key 124 is read, the rKEYJ flag is set at step 5303.

In step 5304, check whether there is a "sort" flag, and if this flag is not present, it is an instruction to set the sort mode, so
At step 5305, the "sort" flag is set, the sort indicator lamp 125 is turned on, and the stack indicator lamp 126 is turned off.

5304, check whether the "sort" flag is present or not.

If this flag is present, it is an instruction to set the stack mode, so in step 8306, the "sort" flag is set to recent, the sort indicator lamp 125 is turned off, and the stack indicator lamp 1 is set.
26 is lit.

When all keys on the operation board are not operated, 530
7 is rKEYJ flag, "dark" flag.

Reset the ``write'' flag, ``enlarge'' flag, and ``shrink'' flag.

5307 and 5308 constitute a loop for controlling the position of the condenser lens 7. In other words, when the target position of the condenser lens 7 corresponding to the value of the variable magnification register does not match the current position of the condenser lens 7, control is required and the condenser lens 7 is driven along the optical axis. The variable power motor (not shown) is energized in forward and reverse directions. If they match, the loop is exited and the variable magnification motor is deenergized at 5310.

Referring again to Figure 5a.

In the above loop for setting copy conditions, the readiness of the copying device is monitored in S13 for each loop. Here, whether or not the copying apparatus is ready for operation is determined based on the temperature rise of the fixing unit 32 and the presence/absence of recording paper in the paper feed system being set.

If the preparation for operation is not completed, in S15, the "red" lamp provided behind the print key 88 is turned on, the copy prohibition indicator lamp 108 is turned on, and <Please wait> is displayed. At this time, the "green" lamp and copy permission indicator lamp 107 provided behind the print key 88 are turned off.

When the operation preparation is completed, in S14, the "green" lamp provided behind the print key 88 is turned on, and the copy permission indicator lamp 107 is turned on to display <Copy possible>. At this time, the "red" lamp provided behind the print key 88 and the copy prohibition indicator lamp 108 are turned off.

See Figure 5b.

When the print key 88 is operated during input reading in S16, it is detected in S17. At this time, the copying machine
If it is not ready, this key operation is canceled at 818.

If the copying device is Ready, then in S19 the Ready status is reset in the same way as above, and the "shift" flag for carry in the set register is also reset.

Although not shown in the figure, if the document sensor of the ADF device 2 detects the presence of a document, the operation of the print key 88 becomes an ADF start instruction, and an interrupt process causes the ADF to start.
The document in the F device 2 is loaded and control is executed. When the ADF holder 2 has placed the original in the predetermined position, the process returns to this step and starts the copying process described above.

If the end cycle is in progress at 520, the start cycle of S21 is omitted, but otherwise it is executed.

In one copy cycle of S22, copy processing is performed under set copy conditions based on the state of each flag, the value of a register, etc. ■Finish copying.

Every time one copy cycle of S22 is completed, the number of copies is incremented by one and displayed on the number of copies display 95 (S23).

In S24, the same parts status reading process as described above (scanning the copying device's protection circuit, reading and displaying the detection mark of the paper feed cassette attached to each stage paper feed tray and the presence/absence of recording paper) is performed, and the abnormality is detected. If not, S2
At step 6, key operation input is read by driver 1 (64) and buffer 1 (65). Here, when the C key 93 is operated, the value of the set register is set to 1 in S28.

529-824-825-326'-527-(S28
)-829-S24-... The loop is repeated until the repeat timing.

At the repeat timing, the number of copies is compared with the number of copies set (set register) in S30, and if the number of copies exceeds the number of copies, the process returns to S22 and one copy cycle is executed again (repeat process).

If the number of sheets set in S30 is less than the number of copies, S31
Set the end cycle with . Although not shown here, the presence or absence of the "double-sided" flag is checked, and if it is present, the presence or absence of the "back" flag is further checked.

If there is no "back" flag, the "back" flag is set, the number of copies is stored in the set register, and the back side copy mode is set. In back side copy mode, S2
Automatically removes the intermediate tray 36 in one copy cycle of two.
Select.

If the ``back J flag'' is present, it means the end of the back side copy mode, that is, the end of the double-sided copy mode, so both the ``back'' flag and the ``double-sided'' flag are reset.

When the end cycle is set, the process returns to S7 again to finish discharging the paper (S I O), and when the end timing comes (
Sll), ends the end cycle and de-energizes the main motor, solenoid, etc.

Note that during this time, the aforementioned input reading and corresponding processing loop is configured, so if the print key 88 is operated during this time, the process advances from S20 to 522, and the start cycle is omitted.

By the way, in this embodiment, when a paper feed cassette containing recording paper of the paper size specified in the call mode is not installed in any of the paper feed trays, the first
In this case, it is the paper feed tray that is equipped with the paper feed cassette that accommodates the largest paper size of the currently installed paper feed cassettes.

Alternatively, a paper feed tray equipped with a paper feed cassette that accommodates recording paper of a size larger than the designated paper size and closest to it may be selected.

Although this embodiment has been described with reference to a so-called electrophotographic copying apparatus, the present invention is not limited thereto. For example, in a hard copy device using a so-called laser printer, which processes image information to perform AO modulation on a laser beam, exposes a photoreceptor, develops it, and transfers a visible image onto recording paper, etc. This can be implemented when adding a function of storing and recalling data in one image processing mode to a facsimile machine that transmits and receives information.

■Effects of the Invention As described above, according to the present invention, in an image processing apparatus, image processing data from the input means is written into the storage means in response to a write instruction from the write instruction means, and the write prohibition instruction means is activated. Since writing to the storage means can be prohibited by the write prohibition instruction, operational errors of the image processing apparatus can be prevented.

For example, by writing image processing data for a frequently used operation mode into the storage means and then setting write protection, the written data can be protected, so that the written data will not be updated inadvertently. .
