Next, the operation will be explained.

When the power switch 101 is turned on, first, the heater 21 in the fixing device 25 is energized and waits until the fixing roller reaches a predetermined temperature at which fixing can be performed (wait state).

When the fixing roller reaches a predetermined temperature, the main motor 18
is energized for a certain period of time to drive the photosensitive drum 20, the fixing device 25, etc., and bring the rollers in the fixing device 25 to a uniform temperature (weight release rotation). After that, the main motor 18 is stopped,
Waits in copyable state (standby state). Then, when a copy command is input from the operation unit 100, a copy operation starts.

(1) Description of image formation In response to a copy command, the main motor 18 rotates, the photosensitive drum 20 starts rotating in the direction of the arrow, the pre-exposure lamp 28 lights up, unnecessary charges on the photosensitive drum 20 are removed, and 1 High voltage is supplied from the high voltage generator HVT to the next charger 31, and a uniform charge is applied to the photosensitive drum 20. Next, after turning on the exposure lamp 24, the optical motor 19 is driven to expose and scan the original placed on the original glass table 5 in the direction of the arrow, and project it onto the photosensitive drum 20.

At this time, unnecessary images can be removed by the laser unit 90, and any part of the image can be erased or a simple document can be written. In this way, an electrostatic latent image is formed on the photosensitive drum 20.

Next, this latent image is developed by the developer 13c or 8, transferred to the transfer paper SH at the transfer charger 15, and separated from the photosensitive drum 20 at the separation charger 16.

Next, the residual toner remaining on the photosensitive drum 20 is collected by the cleaner 6, and after the charge is uniformly removed by a laser beam from a laser unit 90 that removes unnecessary charges on the photosensitive drum 20, the copy cycle is repeated again.

During the image formation described above, the black developer 8 and the color developer 1
3c, 13a, 13b is the operation unit 10
It is brought into contact with the photosensitive drum 20 by a selection command from 0.

That is, by energizing the developing device switching solenoid 7, the black developing device 8 is released, and the color developing device 13c is pressurized (in contact with) the drum. Further, a developing roller 7a of each developing device,
A developing bias voltage is applied to 8a from a high voltage generator HVT.

In addition, the copying machine of this embodiment can perform not only normal one-sided copying but also double-sided copying such as stamp mode, which will be described later, and multiple copying.
The resistance value of the paper and other conditions have changed compared to when copying two sides, and this should be dealt with (transfer charger 15, separation charger 16).
The conditions for the high voltage applied to the first side and the second side during double-sided copying or multiple copying are also different. The respective high voltage values for these developing biases or two transfer separations are determined by commands from the control section 60.

The optical system 4 is reciprocally controlled by rotating the optical motor 19 forward and backward through the motor control section 63 in accordance with commands from the control section 60 . Sl is a home position sensor of the optical system 4, and the optical system 4 is stopped at the position of this home position sensor S1 during standby. S2 is an image leading edge sensor corresponding to the leading edge position of the original image, and is used for timing of copy sequence control. Optical system 4
In response to a command from the control unit 60, the scanner reciprocates with a scanning length according to the cassette size and copying magnification.

The upper and lower paper sensors SIO and S12 are upper and lower glue position detection sensors, respectively.

Hereinafter, since the upper and lower stages perform similar operations, the paper feeding operation for the upper stage will be explained. First, when the cassette 9 is inserted, an upper cassette size detection sensor (not shown)
The size of the cassette 9 is read and the size of the cassette 9 is identified, the out-of-paper indicator of the operation section 100 is turned off, and the cassette size is selected and turned on.

Next, when the copy operation starts with the copy command,
The middle plate in the cassette 9 is raised in advance by an upper stage lifter motor (not shown), and the transfer paper at the position where the middle plate detection sensor SIO outputs is fed into the machine by driving the paper feed roller IO.

During the continuous copying operation, when the number of transfer sheets in the cassette decreases and the top surface of the transfer sheet SH drops below a predetermined position, the upper stage lifter motor is turned on in the same manner as described above to raise it to a predetermined height.

The transfer paper fed into the machine reaches the first registration front sensor S7 and is stopped by the registration roller 12, so it forms an appropriate loop and stops. Next, in order to align the leading edge of the image formed on the photosensitive drum 20, the registration roller 12 is driven by a timing signal from the sensor of the optical system 4, and at the same time, after horizontal registration alignment and leading edge alignment, transfer is performed. The paper is sent to the transfer section 17. After the image on the drum 20 is transferred to the transfer paper by the transfer charger 15 in the transfer section 17, the transfer paper is separated from the photosensitive drum 20 by the separation charger 16 and sent to the fixing device 25 by the paper conveyance section 17a.

In the fixing device 25, the surface of the fixing roller is controlled to a predetermined temperature by a temperature sensor (not shown) placed on the surface of the fixing roller and a heater 21, and the image is fixed on the transfer paper, and then the paper is ejected. The sensor S4 detects the paper discharge, and the paper discharge rollers 26 and 27 discharge the paper to the paper discharge tray 32 outside the machine.

Next, the case of multiple copying will be explained. In the case of multiple copying, the flapper 29 is switched to the position shown by the broken line in the figure by the operation of a solenoid (not shown), and the transfer paper that has been fed, transferred, separated, and fixed as described above is moved to the position shown by the flapper 29. The paper passes through the path 33 and is guided to the second paper feed section 23.
sent to.

Next, in response to a multiple copy command from the operation unit 100, the paper refeed registration roller 37 is rotated, and the transfer paper is sent to the first registration roller 12 section again. Thereafter, the same operation as described above is performed to eject the paper onto the paper ejection tray 32.

In addition, during double-sided copying, the transfer paper is ejected halfway by the paper ejection roller 27 in the same manner as in the above-mentioned normal copying operation, but after the trailing edge of the transfer sheet passes the flapper 29, the paper ejection roller 27 is driven in reverse by a paper discharge motor (not shown), and the transfer paper is guided by a flapper 29 and introduced into a path 33.

The subsequent operations are the same as in the case of multiple copying described above.

In this way, in the case of double-sided copying, the transfer paper is once transferred to the ejection roller 2.
The transfer paper is taken out of the machine from 7, turned upside down by the reverse rotation of a paper discharge roller 27 driven by a paper discharge motor (not shown), and sent to the second paper feeding section 23.

That is, when a document is set, a character input designation is performed using the editor 180, and the copy key 103 is pressed, the designated character is first copied at the position designated by the editor 180, and then a normal analog copy is performed. Note that it goes without saying that analog copying may be performed first. Note that this corresponds to the character input mode and stamp mode described above for the editor 180.

Each of the above-mentioned modes can be used in combination.

Next, the second paper feed section 23 used during screen/multiple copying will be explained. In this embodiment, a second paper feeding section 23 is provided as a transfer paper refeeding mechanism for realizing double-sided copying or multiple copying.

The second paper feeding section 23 is a paper refeeding section essential for realizing double-sided/multiple copying, and when the number of copies is one, there is flexibility in the paper size. However, if two or more sheets of paper are
3, only small size papers can be stacked.

A control procedure for selecting a paper path during double-sided/multiple copying will be explained with reference to the flowchart in FIG.

When a copying operation is started in response to a copy command from the copy key 103, it is first determined in step 27'O-1 whether double-sided/multiple copying is to be performed on the same original without replacing the original. For example, if you are copying a certain part of a document in color and other parts in black, use Y
It becomes ES (affirmative judgment).

In the case of YES, it is determined in the next step 270-2 whether or not the original is a standard size. If the size is not a standard size, the process advances to step 270-6, and the number of copies is one (selected) unconditionally. If it is a standard size, the process advances to the next step 270-3, where it is determined whether the set number of copies is one, and if YES, the process advances to the above-mentioned step 270-6. On the other hand, if No (negative determination), it is determined in step 270-4 whether the transfer paper size is small, and if No, the process proceeds to step 270-4 described above. If YES, it is determined in step 270-5 whether the set copy number is greater than 20 sheets, which is the maximum number of sheets that can be loaded in the second paper feed section 23, and if YES, the process proceeds to step 270-10, and if No, the process proceeds to step 270-5. Proceed to 270-9. In step 270-6, one copy is made and the copied transfer paper is transferred to the second paper feed section 23.
Then, at step 270-6, the transfer paper is fed again from the second paper feed section 23, copies are made, and the transfer paper is discharged outside the machine. In step 270-10, copies are made for the number of sheets set with the numeric keypad 105, and set in the second paper feed section 23, and in step 270-1
1, the paper is re-fed from the second paper feed section 23, copies are made, the transfer paper is discharged outside the machine, and this routine ends.

Further, if the determination is NO in the first step 270-1, the process proceeds to step 270-12. Step 270-1
In Step 2, it is determined whether the original is a standard size or not, and if No, the copy setting number of copies is set to 1 in Step 270-20.
Proceed to step 270-21. If YES in step 270-12, it is determined in step 270-13 whether or not the set number of copies is 1; if YES, step 270
The process advances to -20, and after copying one sheet, the transfer paper is set in the second paper feed section 23.

If No in step 270-13, step 270-1
4, it is determined whether the transfer paper is small size paper or not. If NO, the process advances to step 270-20 and the same routine as described above is performed; if YES, the number of copies is determined in step 270-15, and the number of copies is 20 (sheets). ), then the next step 270-
Step 16: Set the number of copies to 20 and proceed to step 27.
The process proceeds to step 0-17, and if the number does not reach 20 (sheets) or more, the process proceeds to step 270-17.

Next, in step 270-17, step 270-
The set number of copies are made in the same manner as in step 10, and the copied transfer paper is set in the second paper feed section 23.

At the next step 270-18, the original is replaced and a copy command is output, and at step 270-19 a copy is made in the same manner as step 270-9 described above, and this routine ends.

On the other hand, if the size is not the standard size in step 270-12, the set number of copies is set to 1 in step 270-20, copies are made in the same manner as in step 270-5 in step 270-21, and the original is replaced in step 270-22. When the copy command is output, copying is performed in step 270-23 in the same manner as in step 270-11, and this routine ends.

The first question is whether or not double-sided multiple copying with multiple sheets as described above is possible.
Since the sequence program shown in Figure 0 is executed automatically, the operator does not have to think about it every time, and control is always performed using the optimal system. In addition, in the case of a large number of non-standard copies, it is possible to perform copying one by one using the second paper feed section 23.

Furthermore, unnecessary troubles can be avoided by determining the inconvenience of the transfer paper (such as its size being too small) and discharging it outside the machine without performing double-sided/multiple copy processing.

Next, an example of the circuit configuration of the laser unit 90 is shown in FIG. As shown in the figure, the control unit 60 controls the copy designation area operation unit 100. Copy mode specified by editor 180, copy magnification 2 paper size, photo mode.

An address switching circuit 704 and an address switching circuit 704 are used so that while writing ATA to one of the blank RAM (0) 705° blank RAM (1) 706, the area data BDATA can be read from the other and written to the 8-bit shift register 708. A control signal is output to the blank data switching circuit 707.

Next, add-on controls for writing characters, stamps, dates, memos, etc. on copied images will be explained.

According to the control data from the control unit 60, the laser unit controller 700 reads data (character pattern) from the font ROM (character generator) 702 according to the add-on character code, and reads the data (character pattern) from the add-on RAM 72.
Set to 3. The add-on RAM 723 has, for example, 40
It consists of a bitmap that can store dot patterns for characters. The laser unit controller 700 writes add-on character printing position designation data indicating the printing position of the character to the add-on controller 709. When the add-on controller 709 receives the start signal from the laser unit controller 700, it sequentially reads data (character pattern) FDATA from the add-on RAM 723 according to the add-on character printing position designation data, and stores the data FDATA.
is output to the data control circuit 720.

As shown in FIG. 2, the light emitted from the laser 91 is reflected by the rotating polygon mirror 93 and is reflected by the imaging lens 95.
．． 96 and scans over the photosensitive drum 20. that time,
In order to extract the horizontal synchronization signal, a horizontal synchronization signal (hereinafter referred to as BD double signal detection circuit 94) is arranged on the laser scanning.

The horizontal synchronization signal (BD double signal) output from the BD detection circuit 94 is input to the laser unit 90. This horizontal synchronization signal (BD double signal) is input to the pulse width shaping FF (flip-flop) circuit 710 in FIG. After being waveform-shaped, it is input to the pulse synchronization circuit (1) 711. The interrupt terminal of the laser section controller 700 and the pulse synchronization circuit (2) 712.
The horizontal synchronizing signal from the BD detection circuit 94 that is input to the F circuit 710 is called an IBD signal, and the waveform-shaped horizontal synchronizing signal output from the pulse width shaping FF circuit 710 is called an IBD signal.
It is called the D times signal.

The laser unit controller 700 generates an interrupt every time the BD double signal is generated, and blanks the RAM (0) 705.
, writes area data BDATA to RAM (1) 706. Further, the laser unit controller 700 outputs a control signal in the sub-scanning direction by counting the number of interruptions of the BD double signal and the like.

The pulse synchronization circuit (1) 711 outputs a reset pulse H3YMCI to the horizontal synchronization clock generation circuit 713 in synchronization with the rise of the above-mentioned BD double signal. The horizontal synchronization clock generation circuit 713 generates a clock HC synchronized with the BD double signal.

It is composed of a frequency dividing circuit that outputs LK.

Pulse synchronization circuit (2) 712 is horizontal synchronization clock H
A BD signal synchronization signal H3YNC2 is generated using CLK as a reference. The horizontal line counter 714 is cleared by this signal H3YNC2 and counts the horizontal synchronization clock HCLK. The output of the horizontal line counter 714 is input to a timing signal generation circuit 718, and a horizontal timing signal is outputted from the horizontal line counter 714 at the set count number.

Next, a dot erase circuit 71 for forming a halftone image
9 will be explained with reference to FIGS. 13-1 to 13-3.

As shown in Figure 13-1, the dot erase circuit 719
is composed of an 8-bit shift register 724,
As the clock on the shift side, the above-mentioned horizontal synchronization clock H
CLK is being input. That is, halftone dots are formed based on the timing of this horizontal synchronization clock HCLK. 13th
- As shown in the timing chart in Figure 2, the blank signal BLANK indicating the effective image area starts from the rising edge of the BD double signal.
By the rising edge of , halftone data is loaded into the shift register 724 via the data bus DB by the laser section controller 700. Note that this load is performed by the controller 700.
This is performed based on the load signal LOAD from . The output of the shift register 724 is logically ANDed with the blank signal BLANK by an AND gate 725, and is output to the data control circuit 720 as a dot signal DEDATA in the form of a dot pattern.

The 8-bit halftone dot data written into the 8-bit shift register 724 by the laser unit controller 700 is cyclically shifted by the synchronous clock HCLK and output to the AND gate 725.

13-3 (A) to (C) show examples of output halftone dot patterns. In the main scanning direction (laser scanning direction), 8-bit halftone data Do-
A repeating pattern of D7 is output. Regarding the sub-scanning direction (rotational direction of the drum), the laser unit controller 700 transfers specified (arbitrary) halftone dot data (for example, DA
By loading TAO-DATA7), the specified (
(arbitrary) halftone dot patterns can be generated.

The data control circuit 720 of the laser unit 90 receives the character pattern FD from the add-on controller 709.
This gate circuit controls ATA, area data BDATA, and dot data DEDATA from the dot erase circuit 719. That is, the data control circuit 720
For example, character pattern FDATA, halftone dot data DEDA,
TA is selectively output to the laser drive circuit 721 at a predetermined timing. The laser drive circuit 721 modulates the laser using data input from the data control circuit 720.

Next, blank RAM (0) 705 and blank RAM
(1) A control operation for controlling a designated image area using 706 will be described with reference to FIG.

From the control unit 60, data (P s, P r' ) (P2. P2
) is sent to the laser unit controller 700 through the 2 baud RAM 703. Now laser unit 90
Blank RAM (0)705 and blank RAM
(1) It is assumed that each of 706 is configured to have a storage capacity for one line at a predetermined area resolution. Therefore, the area shown in FIG. 14(A) is
When specified from 0, three line memory data (area data BDATA) as shown in FIG. 14(B) are used. Next, from the starting point of Po to Xl, line memory data O is blanked to RAM (0) 70
Read from 5. Blank RAM from Xl to X1'
(1) Read line memory data 1 from 706. Blank RAM (0) between X1' and X2 705
Read line memory data 0 from.

Furthermore, between x2 and X2' is 1. Blank RAM (
1) Read line memory data 2 from 706. X
From 2' to PE, line memory data O is read from blank RAM (0) 705. As a result, the 14th
The regions (P l+ P 1') and (P2
．． The area other than P 2' ) is irradiated with the laser, and the copied image from the original is printed in the areas (P ItP, / ), (P21
P2') only.

Regarding writing of line memory data, the blank RAM that has not been read out is rewritten by the laser section controller 700. Also, when reducing or enlarging, data p sent from the control unit 60 according to the magnification α,
,p,/,p2. Based on p2', P1×α, P2×α,
PI′xα, P2′×α are calculated and the line memory data 0. 1.2 is changed as shown in FIG. 14(C).

Next, the control procedure of the laser unit controller 700 in controlling the designated image area will be explained with reference to the flowchart of FIG. 15. First, in step 800, area designation data and magnification data are received from the control unit 60. Next, in processing step 801, line memory data (area data BDATA) is set in blank RAM (0) 705 from the above-mentioned area designation data and magnification data.

Next, in determination step 802, the control unit 60 waits for an image formation start command to be given. When an image formation start command is given from the control unit 60 in determination step 802, reading from the blank RAM (0) 705 is started in processing step 803.

Next, in processing step 804, blank RAM (1) 7
06, the next line memory data (area data BDAT
A) is set, and in judgment steps 805 and 806 it is judged whether image formation is completed or area data is to be switched.

The end of image formation and the switching of area data are determined by counting the BD double signal from the start of image formation inside the laser unit controller 700, and using that value and Pl.

This is performed by comparing with the sub-scanning position information of P l' * P2 + P2' + PE.

In the case of area data switching, process steps 806 and 807
The read/write RAM is switched at step 808 and step 809, and step 805 and step 806 are executed.
Wait for the timing in the same way as 3, and then proceed to judgment step 809.
If the determination is affirmative, the process returns to step 803 and the above operations are repeated until the image formation is completed.

Next, the password input operation will be explained. In this embodiment, once a personal identification number is registered, it cannot be copied unless that number is input. Further, a plurality of password numbers can be registered, and the cumulative number of copies for each number is stored in a counter RAM 600 provided in the control section 60. Note that this RAM 600 has a backup power source, and its stored contents are not erased even if the power is turned off.

The process will be further explained below with reference to the flowcharts shown in FIGS. 16 to 18.

FIG. 16 shows a control flowchart for permitting copying by inputting a password. First, enter the password using the password type key 13 on the operation panel 100 (Fig. 4).
6, then enter a four-digit password using the numeric keypad 105, and then press the password key 136 again (step 901). This input is checked against all previously registered passwords (step 902), and if no password is found, the system waits for the password to be input again. If found, a timer is set for 30 seconds and a countdown begins (
Step 903).

Then, wait for a copy start command from the copy key 103 until the timer reaches O (steps 904 and 905).
). If the timer reaches 0 before the copy key 103 is pressed, the process returns to step 901 and waits for the password to be input again. If the copy key 103 is pressed before the timer reaches 0,
A predetermined copying process is performed (step 906), and the count RAM 600, which stores the total number of copies prepared for each password, counts up (907).

Then, the process returns to step 903 and repeats the same process.

Further, in this embodiment, the total number of copies for each password stored in the counter RAM 600 can be printed by the laser unit 90 described above. FIG. 17 is a control flowchart of this printing operation. Further explanation will be given below according to this flowchart.

First, by pressing the key 132, pressing the PIN code key 136, and pressing the key 132 again (step 911).
), convert the password and the total number of copies stored in the count RAM 600 into a character code (Step 91)
2), set it in the add-on RAM 723 (step 9
13), and characters are output by the laser unit 90 (step 914). Note that the process of image formation is the same as in the case of the add-on, stamp, etc. described above.

Here, there is a limit to the amount of character codes that can be set in the add-on RAM 732, and in this example, only up to 100 characters can be laser-outputted by setting -degrees. In this example, up to four passwords and the total number of copies in the count RAM can be output at a time.

In this case, the output format on the transfer paper is as shown in FIG. 19 (1).

Furthermore, by resetting the add-on RAM 723 during one cycle of image formation, it becomes possible to output a larger amount of data than in the previous example. FIG. 18 is a flowchart in this case, and in this example, it is possible to output the total number of copies of 12 passwords. In the figure, steps 921 to 924 are step 91 in FIG.
1 to 914.

In step 925, add 1 to n (step 925), n
Step 923 and subsequent steps are repeated until =3 (step 926).

Note that while the add-on RAM 723 is being set, characters cannot be output using the laser, so the laser is turned on for the image portion during that period and a blank area is formed for the rest of the image. The output format on the transfer paper is as shown in FIG. 19(2).

In addition, the capacity of the add-on RAM 723 can be increased (by doing so, an image as shown in FIG. 19 (3) can be outputted on transfer paper with one output during one cycle of image formation without resetting the add-on RAM.

〔Effect of the invention〕

As described above, according to the present invention, it is possible to record management data for each PIN data on a recording material by also using a normal recording means, and the management data can be recorded without using a dedicated printer or the like for tabulation. Print.
