Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a copying machine having a function of imprinting page data.

The copying machine of the present invention is capable of re-inputting the initial value of page data after a jam reset due to paper feeding trouble or the like.

[Conventional technology]

2. Description of the Related Art A copying machine has been proposed (Japanese Patent Publication No. 59-52811) or provided which is capable of imprinting data such as date, page number, etc. on the copied image when copying an original image.

In the copying machine described above, when exposing and scanning a document image to write an electrostatic latent image corresponding to the image on a photoreceptor, for example, the area corresponding to the data imprinting area is shielded from light, etc., and the initial stage of the area is By preserving the charged state, data can be written to the area.

When using page data as the data to be imprinted, first give the page data specified by key input from the operation panel as an initial value, and then perform unit copy operations (continuously copying the same document). A series of copy operations to be performed: For example, each time a series of copy operations (for example, multiple copy operations in the case of normal multi-copy, or one copy operation in the case of single copy) is completed, the value decremented from the initial value (of the original (When copying from the last page)
, or a numerical value incremented from the initial value (in the case of copying from the first page of the original) is sequentially given as page data corresponding to each original.

[Problems that Hathu tries to solve]

When performing a copying operation that involves imprinting page data, a problem such as a jam in the original or copy paper may occur, and the copying operation may be interrupted.

In such a case, handling of the page data when restarting the copying operation after removing the jammed paper becomes a problem.

That is, depending on the location of the jam, the type of jammed paper (whether it is an original jam or a copy paper jam), the time when the jam occurs, and whether or not multi-copying is being performed, etc.
The originals for which the copying operation should be restarted are different, making it difficult to automatically determine the page data.

The present invention is intended to solve these problems.

[Means and operations for solving the problems] The present invention provides: a data imprinting means for imprinting data superimposed on a document image; a veg counting means for counting the end of a unit copy operation;
A copying machine with a data imprinting function, which has a numerical value input means, which sets a page data imprinting mode for imprinting numerical values generated as page data; , a page data management means for managing page data for each unit copy operation interval r; and a numerical input means for inputting a numerical value into the page data when waiting for copy restart after a jam reset under page mode setting. This is a copying machine with a data imprint function.

According to the above configuration, if a jam occurs during execution of a copy operation involving page imprinting, a mode for inputting an initial value of page data is set after jam reset/reset.

Therefore, the operator should take into consideration various circumstances (location of jam, type of paper, timing of occurrence of jam, whether multi-copy or not, etc.) when resuming copying operation. The initial value of the page data can be set accurately.

〔Example〕

The present invention will be explained in detail below.

(Overall description of groove placement) FIG. 1 is a schematic diagram showing the configuration of a copying machine and a document feeder (RDH) according to an embodiment.

The illustrated copying machine has a light/future system 101 on the upper stage. An image forming unit 102 is arranged in the middle stage, a paper refeeding unit 103 is arranged in the lower stage i, and a paper feeding unit 104 is arranged in the lowest stage. A transport device (RDH) 400 is set.

(1) Optical system 101 The optical system 101 is connected to the document table glass 160.
I) F mode) or the document moving on the document table 16 (O document transfer for scanning, j is I?D)
During the exposure point scanning i6 (performed in the panning mode of H), the reflected light from the original image is guided to the photosensitive drum 2 of the image forming section 102, and an image is formed on the surface thereof.

The optical system 101 includes exposure lamps IO1 reflection @11a, Il
b, llc, lid, and lens 12.

Normal mode (modes other than panning mode; panning mode will be explained later) Below, when scanning a document,
The exposure lamp lO and the reflecting mirror 11a move at a speed of V/N (V: circumferential speed of the photosensitive drum 2, N: copying magnification), and the reflecting mirrors i1b and llc move at a speed of V/2N, respectively. It moves back and forth along the bottom surface of the document to expose and scan the document.

On the other hand, under the sink mode using the RDH400, the exposure lamp 10, reflector 11. a, and reflecting mirror 11b/tt
c, is held fixed at the reference position 100. Exposure scanning of the original image in this state is performed by moving the original on the original table 16 at a constant speed to the left in the figure.

The copy magnification can be set by adjusting the position of the lens 12.
Further, the image forming position is corrected by adjusting the angle of the reflecting mirror 11d.

(2) Image forming unit 102 The image forming unit 102 executes image formation by a so-called electrophotographic process. In other words, it develops an electrostatic latent image formed on the photoreceptor drum 2 with toner. is transferred onto copy paper, fixed, and then ejected.

The image forming section 102 includes a photoreceptor drum 2 rotatably supported in the counterclockwise direction in the figure, an erase lamp 7 disposed around the photoreceptor drum 2, a charging adjuster 6, and a data imprinting unit) 200 , developing device 3a (accommodating black toner in this embodiment), developing device 3b (accommodating red toner in this embodiment), transfer charger 5a% separation charger 5b, u
A conveyor belt 8 conveys the transferred copy paper, and a fixing device 9 fixes the toner image on the conveyed paper. Note that the data imprinting unit 200 will be described in detail later.

Further, reference numeral 13 supplies the fed copy paper to the photoreceptor drum 2 at a predetermined timing in synchronization with the rotation of the photoreceptor drum 2.
A pair of timing rollers 14 and 15 are used to transport copy sheets between the transfer charger 5a and a pair of rollers 14 and 15 for discharging copy sheets from the image forming section 102 in the image fixing method.

Note that a solenoid (not shown) is operated to switch between ejecting the copy paper ejected from the image forming unit 102 onto the paper ejection tray 36 or into a paper refeeding tray 58, which will be described later. This is executed by the switching lever 41.

(3) Paper refeeding unit 103 The paper refeeding unit 103 is used for composite copying (copying in which a composite image is formed on the same side of paper through two consecutive image forming processes) and duplex copying (continuous duplex copying). It is used for copying (copying) in which images are formed on the front and back sides of paper through two image forming processes.

That is, the copy paper on which the image has been transferred and fixed on one side (the first side) passes through the paper passing path 530 during composite copying, and passes through the paper passing paths 530 and 531 during double-sided copying.
The paper passes through the paper refeed tray 58 and is temporarily stored in the paper refeed tray 58. That is, the tray 58 is placed so that the image forming surface (first surface) is facing down during composite copying, and so that the image forming surface (first surface) is facing up during double-sided copying. will be stored in.

Thereafter, at a predetermined timing, the paper is pulled out from the tray 58 by the refeeding roller 38, passes through the paper feed path 540, reaches the timing roller pair 13, and again at a predetermined timing, the paper is pulled out from the tray 58 by the refeeding roller 38, and is moved between the photoreceptor drum 2 and the transfer charger 5a at a predetermined timing. Paper is fed, and image transfer and fixing are performed. Note that the paper is fed between the photoreceptor drum 2 and the transfer charger 5a so that the image forming surface (first surface) faces the photoreceptor drum 2 during composite copying, and through the feeder during double-sided copying. If so, the image forming surface (first surface) should face the transfer charger 5a side.

(4) Paper Feed Unit 104 The paper feed unit 104 has an upper paper tray 42 and a lower paper tray 43 that accommodate sheets of eight different sizes.

After the paper in each tray is pulled out by paper feed rollers 18 and 19, the paper is fed by an automatic paper feed mechanism to the timing roller pair 13 of the image forming N102, and is fed to the timing roller pair 13 of the image forming N102 according to a predetermined timing signal from the optical system 101 or the RDH 400. depending on,
In addition, in synchronization with the rotation of the photoreceptor drum 2, the photoreceptor drum 2 is sent between the transfer chargers 53 and subjected to image transfer.

(5) Document Circulation Conveyor (RDH) 400 The document circulation device (RDH) 400 continuously feeds the document set on the document tray 412 onto the document table 16 from the right end side in the figure. 16 to the left in the figure at a constant speed, and then collects the document back into the document tray 412 from the left end side in the figure, and is used by setting it on the document table 16 of a copying machine. . The RDH400 can be used in panning mode and non-panning mode (ADF).
mode).

The document feeding by the RDH 400 is performed as follows.

First, place the document on the document tray 412 with the image side facing up (
The stacked documents are sequentially pulled out by a paper feed belt 420 starting from the lowest document and fed onto the document table 16. At this time, the passage of the fed document is detected by the paper feeding detection sensor 421.

Next, the document that has passed the position of the paper feed detection sensor 421 is (i) In the panning mode, after a predetermined timing is taken at the entrance to the document table (on the right side of the figure), the document is transferred to the conveyor belt. Due to the frictional force of 423, the original platen 16 moves at a constant speed.
It is exposed and scanned while being conveyed to the left in the figure.

At this time, as described above, the exposure lamp 10 and the reflecting mirror 11allbllc of the optical system 101.

is held fixed at the reference position.

In other words, exposure scanning of the original image in the panning mode is performed not by movement of the optical system but by movement of the original.

After that, the original is ejected from the exit of the original table (left end side in the figure) by the ejection roller 425, and returned to the original tray 425.
It is collected on 2.

In panning mode, the distance between the vapors is narrow,
It is necessary to know in advance how many pages the final manuscript will be. Otherwise, several sheets of paper will be fed even after the final original is copied. Therefore, there is a count mode that feeds the original document before copying starts.

In count mode, the first document to be collected (-
The first document fed (first document) is not collected directly on top of the top layer document (final document) set in the tray 412, but is collected as a stack of first document and final document. A lever 410 for detecting the final document is interposed between them.

That is, when a document is first set on the tray 412, the tip of the lever 410 is placed on the uppermost document (the final document). The tip of the lever 410 gradually descends as the thickness of the document decreases as the document is fed, and when the final document is pulled out from the tray 412, it comes into contact with the final document feed detection sensor 411. As a result, it is detected that the final document has been fed.

The detection of the final document feeding is provided as data necessary for counting the number of document sheets, etc., as will be described later.

Therefore, by (count value) x (set number of copies),
The total number of copies can be known in advance, and the final copy can be detected.

As can be seen from the above, document copying by panning is performed with the scanner in a stopped state, so there is no loss time due to scanner returns.

Therefore, compared to copying in the normal mode (non-panning mode), there is an advantage that the interval between each copying operation can be shortened and high speed can be achieved.

On the other hand, in (11) non-panning mode (a mode in which the RDH is used as an automatic document feeder (ADF): ADF mode), the document that passes the position of the paper feed detection sensor 421 is first , and is stopped at a fixed position on the document table 16 (a position for scanning the document by moving the scanner).

In such a document stopped state, the exposure lamp 1 of the optical system 101
0. The reflecting mirror 11a is at a speed of V/N, and the reflecting mirror 11a is
b-11c are each driven at a speed of V/2N,
It moves along the lower surface of the document platen glass 16 to expose and scan the document.

After the exposure scan is completed (in the case of multi-copying, after the exposure scan is completed for the number of multi-copies), the document in the above-mentioned fixed position is conveyed on the document table 16 to the left in the figure by the frictional force of the conveyor belt 423. Thereafter, the document is discharged from the exit (left end in the figure) of the document table by a discharge roller 425 and collected onto the document tray 412 again.

(iii) Note that the RDH 400 can be opened and closed. That is, the RDH document conveyance section 405 can be opened upward on the operator side, and the document table 16 can be opened upwardly from the operator side.
It is configured so that the original can be manually set on the top.

(Description of data imprinting unit 200) FIG. 2 is an explanatory diagram of the configuration of the data imprinting unit 200.

As shown in FIG. 2, the LED head 201 of the data imprinting unit 200 is configured to be movable. Note that the direction of the movement is along the axial direction of the photoreceptor drum.

Here, the movement of the LED head 201 is achieved by driving the driving pulley 211 by the stepping motor 204, and driving Boo! This is performed by rotating the belt 205 stretched between J 21 t and the driven pulley 9211.

That is, as shown in the figure, a data imprinting head 20 in which an LED array 203 and a charger 202 are integrated.
1 is fixed on the belt 205. Therefore, as the belt 205 rotates, the data imprinting head 2
01 moves along the axial direction of the photosensitive drum 2.

Note that 208 is a sensor that detects a reference position of the data imprinting head 201 (a position that serves as a reference for counting of counters CNTRt and CNTR2, which will be described later). That is, the reference position is detected by the light shielding plate 209 protruding from the data imprinting head 201 cutting off the optical circuit in the recessed portion of the sensor 208 .

Further, the data imprinting unit 200 equipped with the data imprinting head 201 is removable from the copying machine, and furthermore, the data imprinting unit 200 is compatible with the developing device when attached to the copying machine. It is configured to have.

As described above, in this embodiment, the length of the data imprinting head 201 is configured to be shorter than the length of the photoreceptor drum 2, and a head shifting mechanism is employed to transfer data onto the photoreceptor drum 2. It is possible to imprint data to any location on the screen. However, the present invention does not limit the length of one node 201 for data imprinting. That is, it is also possible to set the data imprinting position by employing a data imprinting head that is approximately the same length as the photosensitive drum 2 and controlling the lighting/extinguishing of its LED elements.

(Description of Operation Panel) FIG. 3 is an explanatory diagram showing a part of the operation panel of the copying machine.

As shown in the figure, the number of copies, total number of pages, or JAM page number (the number that is entered first when copying is resumed after a jam reset; details will be described later) is displayed on the operation panel.

Furthermore, when the total number of pages is input, the page display imprinted on the copy paper is expressed as */** (*: current page, **: total page).

Further, the color specification key 312 is used to select the toner color of the topmost developing device (in this embodiment, the data imprinting unit 200 is installed in the topmost tier, not the developing device); The color designation key 314 corresponds to the toner color of the developing device 3a in the middle stage, and the color specifying key 314 corresponds to the toner color of the developing device 3b in the lower stage.

(Description of Control Circuit) FIG. 4 is a block diagram showing the configuration of the control circuit of this copying machine.

As shown in the figure, the control circuit includes a CPU 22 (host) that controls the operation of the entire copying machine, and a data imprinting unit 200.
It is mainly composed of an imprinting CPU 21 which controls the imprinting CPU 21.

Key input signals from the operation panel, time data from the timer IC, timing data from the imprinting CPU 21, and data from the CPU that controls the RDH (mode data such as panning mode, etc.) are input to the CPU 22. At the same time, signals from various sensor groups (not shown) arranged at various locations within the copying machine are input.

The host CPU 22 also sends a display output signal to the operation panel, imprint data (position data, image data, etc.) to the imprint CPU 21, an image area interrupt request signal to the imprint CPU 21, and a CPU that controls RDH. At the same time, control signals are output to controllers of various members (not shown) disposed at various locations within the copying machine (scanner, developing device, fixing device, etc.).

On the other hand, in the imprint C, PU21, the above-mentioned host) CPU2
2, a timer interrupt request signal from the timer IC, font data from the character ROM, and reference position data from the photosensor 208 are input.

In addition, from the imprinting CPU 21, the host CPU 2

Furthermore, each mode is initialized (S3).

In step S5, a routine timer that defines the routine time is started (S5).

In step S7, the CPU 21 (imprint control CPU

S15).

Also, if the copy start flag is set (51
7: YES) executes the copy start routine (
519).

Steps 516a-516d are processes related to jams. When the occurrence of a jam is detected in step 516a, the jam reset flag is reset to 0 in step 516b, and the process is stopped. In step 516c, a check is made to clear the jam, and when the jam is cleared, step 51
At step 6d, the jam reset flag is set to 1. In addition,
Jam detection means and jam release detection means for copying machines are already known, and will be described here as side chambers.

In step S21, other processes (processes other than those described above executed by the CPU 22; details omitted because they are not directly related to the gist of the present invention) are executed.

Thereafter, in step S23, the routine timer waits for the end of the routine timer, and the process returns to S5 to repeat the process.

) and the copy start routine (S19) will be described in detail later.

(2) Main routine of the imprinting CPU 21 FIG. 15 is a flowchart showing the main routine of the imprinting control CPU 21.

The CPU 21 starts processing, for example, by turning on the power, and first initializes each register, flag, etc. (Sto
ol).

In step 31003, it is determined whether or not data is to be imprinted, that is, whether or not the data imprinting mode is in effect. If the imprinting mode is not in effect (31003; No), an image area interrupt is executed to control the imprinting start timing. by prohibiting (
S1025), the process returns to 51003.

On the other hand, if it is determined in step 81003 that the mode is data imprinting mode (S1003; YES), the process advances to step 51005.

In step 51005, it is determined whether or not the imprint data and imprint position data have been changed.

As a result of the determination, if it is determined that there is no change in any data (51005; No), step 51007
Jump to 51015 and proceed to step 51016a.

On the other hand, if the result of the determination in step 51005 is that there is a change in the imprint data and/or imprint position data (S1005; YES), processing corresponding to the change is executed.

That is, first, the execution of the copy operation is prohibited (5t007).
, takes in the total page number data sent from the host CPU 22 (SIO09). Next, bitmap development of the standard data for imprinting is executed (51011), and a motor control routine for controlling the position of the data imprinting head 201 is executed (S1013). After that, the copy operation is permitted (S1015).

In step 51016a, the JAM IJ upper set number (S629; first
(see Figure 0) is determined. As a result, if the JΔM reset signal is detected (S 1015a; YES)
Please set the JAM flag on the imprint side 51016b
), and also takes in the JAM page number data (S215; see FIG. 7) sent from the host CPU 22 (S
1016c).

Thereafter, the process advances to step 51017.

In step 51017, it is determined whether it is the timing to start copying operation processing for each sheet.

If it is not the copy start timing (S1017・No
) jumps steps 51019 to 51023 and returns to step 51003.

On the other hand, if it is determined in step 51017 that it is the timing to start copying, it is determined whether or not there is a change in the time data for imprinting and the page number data (S1
019). As a result, time data for imprinting and/or
Or, if the page number data has changed (S10
19; YES), bitmap expansion of the changed data is executed (S1021).

After that, enable the image area interrupt 5t023>

Details of the bitmap development routine (S1011), motor control routine (S1013), and time/page data bitmap development routine (S1021) will be described later.

CB) Detailed explanation of each subroutine step <1> Host C
Subroutine (1) Analysis Routine (S9) of PU 22 FIG. 6 is a flowchart of the analysis routine (S9) called within the main routine of the host CPU 22.

In this routine, each process in the page data imprinting mode is executed based on the data received in the communication process (S7).

That is, a page count routine (SIOI) that manages the imprint page number, a total page mode check routine (S103) that manages the input of the number of m pages, and a reset of the page data imprint mode when copying of a predetermined number of sheets is completed. Page mode reset check routine (S105) to manage page data after JAM processing in page data imprint mode
The AM processing routine (3107) and other analysis processing are executed.

The details of the page count routine (SIOI), &Q page mode check routine (5103), and page mode reset check routine (S105) are as follows.
It is described below.

Page Count Routine (SIOI)> FIG. 7 is a flowchart showing the page count routine called in the analysis routine (S9).

This page count routine manages imprint page numbers in page mode. Note that managing page numbers on the host CPU 22 side during the panning mode is unreasonable in terms of data transfer speed, so management is performed on the imprint control CPU 21 side (described later).

First, in step 5201, the page LED 304 is determined.

As a result of the determination, if the page LED 304 is not ON, that is, if it is not the page data imprint mode (320
1; No), this routine is not executed and returns.

On the other hand, as a result of the determination in step 5201, the page LED
304 is ON, that is, in the page data imprinting mode (S201: YES), the process advances to step 5203 and checks whether or not the number of misprinted pages has changed, in other words, the new total number of pages. It is determined whether the total number of pages has been determined by inputting or by counting the number of originals when using RDH (described later) (5203).

As a result of the determination in step 5203, if the total number of pages has changed (S203; YES), the internal variable: PAG
After assigning the changed total number of pages to E (3213)
, the process advances to step 5215 to execute PAGE data transfer processing.

On the other hand, if it is determined in step 5203 that there is no change in the total number of pages (5203; NO), step 5
Proceed to 204a.

In step 5204a, the JAM page input input rough flag is set. The JAM page input completed flag indicates the jam processing (
After the process (such as removing jammed paper) is completed,
This flag is set when the operator inputs the number of pages again (S598a, 5598b, 5
598c; see Figure 10).

As a result of the determination in step 5204a, if the JAM page input is rough left (S204a; YES)
) proceeds to step 5204b, and assigns a value obtained by adding the value "l" to the "number of rJAM pages" to the variable: PAGE. "rJAM page number" is determined in step 559, which will be described later.
8b (FIG. 10), which gives the first page data when copying is resumed. After that, set the JAM page input rough flag (S20
4C), proceed to step 5205.

If the JAM page input rough flag is set in step 5204a (S204a; No), the process directly advances to step 5205.

In step 5205, it is determined whether the mode is a panning mode using RDH. As a result, if it is not the RDH panning mode (S205: NO), the condition is that the copy paper has passed the timing roller 13 (5207: Y-ES), and the condition that the set number of copies has been completed ( S209; YES), the data of internal variable: PAGE is decremented (S211)
, the process advances to step 5215 to execute PAGE data transfer processing.

Note that if it is determined in step 5205 that the camera is in the panning mode, or if it is determined that the copy paper has not passed the timing roller 13 in step 5207,
Alternatively, if it is determined in step 5209 that the multi-copy is not completed, the process directly returns to the analysis routine.

Total page mode check (5103) > Figure 8 shows
12 is a flowchart showing the total page mode check routine called in the analysis routine (S9).

First, in step 5301, the page LED 304 is determined.

As a result of the determination, if the page LED 304 is not ON, that is, if it is not the page data imprint mode (330
1; No), the process advances to step 5317, and the liquid crystal display 33
0 (see Figure 14) and return.

On the other hand, as a result of the determination in step 5301, the page LED
If 304 is ON, that is, if it is the page data imprint mode (5301; YES), the process advances to step 5303, and the total page input flag is determined.

As a result of the determination, if the total page input flag is set, the process advances to step 5317 and the liquid crystal display 330 is set to 0.
FFt and return.

On the other hand, as a result of the determination in step 5303, if the total page input flag has been reset, that is, if the total number of pages has not been determined (S303, YES), the process advances to step 5305, and the mode using RDH is determined. Determine whether or not.

If the result of the determination is that the mode does not use RDH (5
305; No) displays display pattern a (see Figure 14) on the liquid crystal display 330 on the operation panel to prompt the operator to input the total number of pages 5315)
, return to the parsing routine.

If the result of determination in step 5305 is that the mode uses RDH (S305; YES), the process advances to step 5307, and it is determined whether or not RDH is to be used in panning mode.

As a result of the determination, if it is panning mode (S307; YE
S) In the present embodiment, prior to the copying operation, the document feed is executed in order to count the number of document sheets, so there is no need to input the total number of pages.

Therefore, in this case, on the liquid crystal display 330,
Display pattern b (see Figure 14) 5309
), return to the parsing routine.

On the other hand, if the result of the determination in step 5307 is that the RDH is not to be used in the panning mode, that is, if the RDH is to be used in the ADF mode (S307; No), the copying machine of this embodiment Since imprinting cannot be processed, the page LED 304 indicating that the page data imprinting mode is turned off to cancel the page imprinting mode (5311), and furthermore, to notify the operator that the page imprinting mode has been canceled. , the display pattern d (see figure 314) is displayed on the liquid crystal display 330 (S3]3), and the process returns to the analysis routine.

Note that, as described above, in this embodiment, control is adopted in which, in the panning mode, the number of originals is always counted by performing blank feeding of the originals. Therefore, step 5307
The judgment in ``is in panning mode or not?'', but if it is in ``panning mode'',
You can select two mode settings: "a mode in which the number of originals is counted by skipping the originals before copying" and "a mode in which copying is performed immediately by panning without rapidly feeding the originals". If it is desired to perform the same operation, a slightly different control must be adopted and the display pattern of the liquid crystal display section 330 must also be changed. However, the basic concept in that case may be the same as above.

<Page Mode Reset (5105)> FIG. 9 is a flowchart showing the page mode reset check routine called within the analysis routine (S9).

This routine is a process for canceling page mode in response to the completion of a series of copy operations under page mode.

First, in step 5401, the page LED 304 is determined.

As a result of the determination, if the page LED 304 is not ON, that is, if it is not the page data imprint mode (S40
1; No), this routine is not executed and returns.

On the other hand, as a result of the determination in step 5401, the page LED
When 304 is ON, that is, when the page data imprint mode is set (S401; YES), R
Determine whether it is panning mode using DH (S

As a result, if it is in panning mode (3403; YE
S) is based on the completion of copying the set number of sheets by panning (S405: YES), and if it is not in panning mode (8403; No), the total number of pages is empty flag is set (S407, YES), And, on the condition that the internal variable: PAGE is 0 (S40
9: YES), proceed to step 5411.

If the above conditions are not met, that is, if it is recognized that the set copying process has been completed in page mode, the page LED will be turned on to reset the page mode.
304 to 0FFL (S41■). Also, to indicate to the operator that the page mode has been reset, the display pattern e (
(see FIG. 14) is displayed (5413).

After the above processing, the process returns to the analysis routine.

(2) Key input processing routine (315) FIG. 1O is a flowchart of the key input processing routine (S15) called within the main routine of the host CPU 22.

Flag Management Steps 3501 to 5523 are steps for setting and resetting the date imprint flag and page imprint flag in response to turning on the imprint key 302.

That is, if the ON edge of the imprint key 302 is detected (S501; YES), the date LED 303 and page LED 304 should be determined.S503.5505.551
5) Depending on the results, set/reset the date imprint flag and page imprint flag.

For example, date LED 303 = OFF (S 503; Y
ES), page LED304=OFF (S505; Y
ES), please sell the 54 inch flag 5507
), the page flag is reset (S509).

Similarly, date LED303-OFF (S503;Y
ES), page LED 304 = ON (S 505;
If No), a date flag and a page flag are set (S511.S513).

Similarly, date LED303-ON (S503;N

S), reset the date flag 5517),
A page flag is set (S519).

Also, date LED303=ON (S503; NO)
, page LED 304=ON (S505; NO), the date flag and page flag are reset (S521.5523).

In steps 8525 to 5531, insert key 30
Corresponding to ON edge 5, if insert mode is set at the time of the ON edge (S527; YES)
If the insert flag is reset (5529), on the other hand, if the insert mode is not set (S527
;No) sets the insert flag (S531
) execute the process.

Note that the insert mode is a mode for setting additional information of the imprint data (for example, the total number of pages in the page imprint mode), and its selection state is displayed by the insert 1-LED 306. .

In step 5533, color select key 312.3
13. Determine whether the ON edge of 314 is detected.

As a result, color select key 312.313.314
If the ON edge of any key is detected (S53
3; YES) sets the color flag (S535
). On the other hand, if the ON edge of any color select key is not detected (8533; No), the color flag is reset (S537).

Note that the color flag is a flag indicating that any color select key has been pressed.

In step 5539, it is determined whether an ON edge of a key in the numeric keypad unit 315 has been detected.

As a result, if the ON edge of any key in the numeric keypad flag) 315 is detected (S539; YES),
Set the numeric keypad flag (3541). On the other hand, if the ON edge of any key in the numeric keypad unit 315 is not detected (S539: No), the numeric keypad flag is reset (S543).

Note that the numeric keypad flag is a flag indicating that any key in the numeric keypad unit 315 has been pressed.

Mode control> In step 5545, the date flag is determined.

As a result, if the date flag is set (S545: Y
ES) turns on the date LED 303 (S549) on the condition that the imprint unit 200 is installed in the copying machine (S547; YES). Date LED3
03 is an LED display indicating that date data has been selected as imprint data (=date imprint mode has been set).

On the other hand, if the date flag is off (S545; No)
Or, if the imprinting unit 200 is not attached (5547; No), the date LED 303 is turned off (<5551).

In step 5553, the page flag is determined.

As a result, if the page flag is set (S553;
YES) is on the condition that the imprint unit 00 is installed in the copying machine (S555; YES), S
The process advances to 557 and the page LED 304 is determined. The page LED 304 is an LED that indicates that page number data is selected as imprint data (=page imprint mode is set).

As a result of the determination in step 5557, the page LED is OFF.
If it is F (S557: YES), the page imprint mode is set. That is, it is determined whether or not to use RDH (S559), and if RDH is not used (S5
59:No) requires input of the total number of pages,
Set the insert flag (3561). Furthermore, since the total page data is unconfirmed, the total page number flag is reset (S563). Then page LED3
04 is turned on (S565). This sets the page imprint mode.

Note that if the page flag is off in step 5553 <S553: NO), or in step 5555
If the imprint unit 200 is not installed (S
555; NO) is a case where there is no imprinting of page data (impossible), so the page LED 304 is turned off.
(5567) to cancel the page imprint mode.

In step 8569, the insert flag is determined.

If the insert flag is set (S569: YES
) should judge page L, ED304 5573), O
Under the condition that it is N (S573: No), the insert LED 306 is turned on (S579). The insert LED 306 is an LED indicating the selected state of the insert mode.

From step 5579, proceed to step 5580a,
Determine the number of JAM pages inputted.

The number of JAM pages has been inputted in step 55, which will be described later.
This flag is set in 98c and indicates that the number of JAM pages has been input.

As a result of the determination, if the JAM reset flag is set (S580a: YES), the process directly proceeds to step 55.
Proceeding to step 83, if the JAM reset flag is not set (3580a; NO), the display (f) is displayed on the liquid crystal display (S580b).

On the other hand, if the insert flag is off in step 5569 (3569: No), or the date LED 303
・When both page LEDs 304 are OFF (S5
71: YES and 5573; YES) turns off the insert LED 306 (S575). This cancels the insert mode.

In step 5583, the color flag is determined.

If the color flag is set (S583; YEl is
The condition is that the color developing device corresponding to the selected color is installed in the copying machine (3585: YES)
), Variable: Set and store the selected color in the copy color 5587), Color selection LED 31

N (S 591).

In step 5593, the numeric keypad flag is determined.

If the numeric keypad flag is set (S 593゜YES
) proceeds to step 5595 and determines whether insert mode is set.

If insert mode is not set (S595:
No) is the input state for the number of copies, so the input value is set and stored as the number of copies (S 603
).

On the other hand, if it is determined in step 5595 that the insert mode is selected (S595: YES), the page number data imprint mode is set (
S59T; YES), proceed to step 5598a,
Determine the JAM reset flag.

As a result of the determination in step 5598a, J A M IJ
If the upper set flag has been reset (S598a:
If NO), the input numerical value is set and stored as the total number of pages (5599), and the total number of pages empty flag is set (S601).

On the other hand, as a result of the determination in step 5598a, if the JAM reset flag is set (S598a; YE
S) sets the input value as the number of JAM pages.
5598b), and also sets up the JAM page number input column (S598C).

After that, the numerical value inputted and stored as the total number of pages, the number of JAM pages, or the number of copies is displayed on the numerical display section 319.
(S605).

Other Processes> In step 5607, it is determined whether the ON edge of the copy start key 308 is detected to start the copy operation (5607).
60? ).

When the ON edge of the copy start key 308 is detected (S
607 ; YES) determines whether document counting by RDH is necessary.

That is, first, it is necessary to determine whether to use RDF (and, if so, whether to use RDH in panning mode S 609.5611), and as a result, when using RDH in panning mode. (S609: YES, and S
611 ; YES) sets an RDH count flag (S613). The RDH count flag is a flag for executing document count processing by RDH.

On the other hand, when not using RDH, or even when using RDH, when using in ADF mode (S
609; No or 5611; No) lowers the RDH count flag (S615).

Thereafter, a copy start flag is set (S617).

As will be described later, the copy start flag is a flag for starting a series of copy operations, and is not a flag for controlling the start of each copy operation.

In step 5619, it is determined whether the all reset key 321 is on-edge, and if detected (S619
;YES) is the date LED 303, page LED 304
, cancel date mode and page mode, and reset various other modes to their initial states (56
21).

Steps 5631-S635 are the same as steps 8501 and 8501 above.
This step collectively shows the processing for inputting any operation keys not mentioned in steps 5617 to 5617.

That is, if the ON edge of another key is detected (S
631 ; YES), the process corresponding to the detected key input is executed (S635) on the condition that insert mode is not set (S633 ; YES).
).

After the above processing, the process returns to the main routine.

(3) Copy start routine (517) Figure 11 shows:
It is a flowchart of a copy start routine (Si2) called within the main routine of the host CPU 22. As described above, this routine is called on the condition that the copy start flag is set (S17; YES). Furthermore, this routine is not a routine that manages the start of each copy operation, but a routine that manages the start of a series of copy operations.

First, in step 5700, the JAM reset flag is checked to determine whether or not a jam is in progress.

In this embodiment, this determination is automatically performed by various paper detection sensors built into the copying machine. However, since this is publicly known, it will not be described in detail. Of course, this may be done manually by the user's key input or the like.

When the JAM reset flag is 1, the process advances to step 5701, and when the JAM reset flag is 20, the process returns as is.

Next, in step 5701, the RDH counter I flag is determined (3701).

If the RDH count flag is set (5701:
No) executes the RDH count routine (571
3). As will be described later, the RD f (counting routine) is a routine for blank feeding the original and counting the number of originals prior to the copying operation.

On the other hand, if the RDH count flag is off in step 5701 (3701; YES), it means that the RD) is not used, or that the RDH is used in ADF mode, or that the RDH count flag is off (3701; YES). This is a case where the sheet number counting process has been completed. In this case, the process advances to step 5703 and the page LED 304 is determined.

When in page imprint mode (5703; YES)
On the condition that the total page number input flag is on (S705, YES), the timer count variable: tl is set to O5707), and the timer for timer interrupt during copying is activated (S70]). . As a result, the "during copy timer interrupt processing j" described later is started, and the copy operation processing is started.
(see Figure 4) is turned off (3715).

On the other hand, in 5705, if the total number of pages input flag is off, in other words, if RDH is not used or RDH is used in ADF mode, the page data imprint mode is Sereno).・If the total number of pages has not been entered (S705)
:No), display pattern C (see Figure 14) on the liquid crystal display 330 on the operation panel.5717
), also lower the copy start flag (5719
), disables copy start.

In addition, if the JAM page number input completed flag is not set in step 5706b, in other words, the JAM page number input completed flag is not set.
After setting M IJ, if the page data imprint mode is selected but the number of JAM pages has not been input (S706b; No), the display pattern f will be displayed on the liquid crystal display 330 on the operation panel.
(See FIG. 14) is displayed (5706c), and the copy start flag is lowered (5719) to invalidate the copy start.

Note that if the page LED 304 is OFF in step 5703, or if the J and M reset flags have been reset in step 5706a, the processes of steps 3707 to 5715 are immediately executed. In this case, a copy is made without image imprinting.

After the above processing, the process returns to the main routine.

<RDH count routine (S7+3)> Figure 12 shows
12 is a flowchart showing an RDH count routine (5713) called within the copy start routine.

In step 5801, it is determined whether the end of a series of originals on the original tray 412 (=feeding of the last original) is detected by the original detection lever 418 and the detection sensor 419 of the RDH unit 400 (3801) .

If the end of the original is not detected (S801; No)
The next document is fed (5803), and on condition that the trailing edge of the next document is detected by the document detection sensor 410 (S805; YES), the document counter is incremented (S807).

Further, in step 5801, if the end of the originals on the original tray 412 is detected (S801; YES), feeding of the next original (the first original after one round of original feeding) is stopped. ), lowers the RDH count flag (S811). Furthermore, the value of the manuscript counter counted by this routine is substituted for the variable: total number of pages (5813), and the &t number of pages several people payment flag is set (S
815). After that, reset the document counter to 0 (
5817).

After the above processing, the process returns to the copy start routine.

(4) Copy 924 Interrupt Routine FIG. 13 shows a copying timer for controlling various copy operations, which is processed by hardware interrupts in the host CPU 22 in response to a timer interrupt request signal from an interrupt timer IC. 3 is a flowchart of an interrupt routine. Note that the interrupt timer is set at step 5709 in the copy start routine.
is activated by

First, when a timer interrupt request signal from the interrupt timer IC is input to the host CPU 22, the CPU 22 saves each register (not shown) and transfers control to this routine.

Next, in step 5901, a variable Tn is defined in advance as a timer count value according to various copy operation control timings (n is 12
, . . . ) and the count value of the timer count variable: tl match (S901).

As a result of the determination, if Tn and the count value of the timer count variable; tl match (S901; YES), a copy operation control signal corresponding to n is generated (S903),
Also, it is sent to the corresponding controller. Note that one of the signals transmitted by the processing in steps 5901 and 3903 is an image area interrupt request signal that controls the data imprinting start timing. In response to the interrupt request signal, an image area interrupt routine is activated in the CPU 21, as will be described later.

In step 5905, it is determined whether the value of the variable Tε in which the count value of the copy operation end timing is specified matches the count value of the timer count variable tl (S905).

If the two match (5905; YES), the process advances to step 5907, and it is determined whether or not the series of copying operations has been completed. If it has been completed (S907: YES), the timer is stopped (5909). Stops generation of timer interrupt request signals. On the other hand, if the series of copy operations has not been completed (S907; No), control processing for the next copy is executed (5911). For example, the timer count variable: tl is set to an appropriate value.

In step 5915, the timer count variable tl is set to
Add to which defines the timer interrupt period. Thereafter, the saved registers are restored (not shown) and the process returns to the one before the interrupt.

2> Subroutine (1) Pitmap development routine of the imprinting CPU 21 FIG. 16 shows the bitmap development routine (S1011) called in the main routine of the imprinting CPU 21
) is a flowchart.

First, the request flag indicating that the content of the imprint data has changed (0: no change, l: change, see communication interrupt routine described later) is determined (51101), and if the request flag is off (SIIOI; No), the process returns to the main routine.

If it is determined in step 31101 that the request flag is set (S l 101 ; YES), read one character of the data stored in the imprint data buffer (see communication interrupt routine described later). 5110
3) Determine whether the character data food is a code representing time data or a code representing page data (51105.51107).

As a result of the determination, if the read character data code is a code representing time data (51105; YES), a predetermined time data imprinting format (e.g. ＊＊＊＊
Data is expanded according to year ** month ** day; ** hour ** minute ** second, where * is a number) (S1117)
, the expanded data is converted into bitmap data based on the font data stored in the ROM 23 or the like (S1119). Furthermore, the time data reporter position is stored in the internal variable: TP so that the time data can be updated in the time/page bitmap expansion routine (described later) (S1121).

Furthermore, if the successive character data codes are codes representing page data (51107; YES), similarly to the case of time data, a predetermined page data imprinting format (in this embodiment, P.

○○/XX, 00 is the page number, XX is the total number of pages), data is expanded (S1111), and converted to bitmap data in the same manner as above (311
13). Furthermore, in the time/page bitmap expansion routine (described later), page number data can be updated.
The page data reporter position is stored in the internal variable: PP (S1115).

Note that if the read character data code is neither a code representing time data nor a code representing page data (51105; No, and 5l107; No>
converts the character corresponding to the character code into bitmap data based on the font data stored in the ROM 23 or the like (51109).

In step 51123, the bitmap data converted in the above step is stored in the imprint data area (
51123).

After that, it is determined whether the bitmap conversion of all the data in the imprint data buffer has been completed.51125>
If it has not finished (S1125; No), return to step 51103 and similarly process the next one in the buffer.
Read characters and continue bitmap conversion.

If it is determined in step 51125 that the bitmap conversion of all data in the imprint data buffer has been completed (S1125; YES), the request flag is lowered (31127), and the process returns to the main routine.

Note that in this embodiment, the imprint data includes time data,
Although the case of page number data has been described, if processing is performed based on this flowchart, it is possible to imprint any character string. However, the condition is that an input processing routine for imprinted character string data is prepared.

(2) Motor control routine (81013) Figure 17 shows the following:
3 is a flowchart of a motor control routine called within the main routine of the imprinting CPU 21. FIG.

First, it is determined whether CNTR2 and CNTR1 are equal, in other words, whether the imprinting head 201 is at the imprinting position [(target position) defined by the position data from the CPU 22 (S1201). . Here, CNTR2
is a step counter that converts the target position of the imprinting head 200 into the number of steps of the stepping motor 204, and CNTR1 is a step counter corresponding to the current position of the imprinting head 201.

In step 51201, if CNTR2 and CNTR■ are equal (S1201; YES), the excitation of the stepping motor 204 is turned to 0FFL (S1203), and the process returns to the main routine.

/ Meanwhile, in step 51201, CNTR2 and cNTRI
are not equal (S1201; No), step 5
The process advances to step 1205, where the excitation state of the stepping motor 204 is determined, the excitation is turned on (S120?), and the process advances to step 51209.

In step 51209, CNTR2 and CNTR1 are compared in size. As a result, if CNTR2<CNTR1 (51209: No), the excitation signal of the stepping motor is set to shift the imprint head 201 to the right (S1211), and the slide counter CNTR1 is decremented (51213). )
.

On the other hand, in step 51209, if CNTR2>CNTR1 (S1209; YES), the excitation signal of the stepping motor is set to shift the imprinting head 201 to the left (51215), and the step counter CNTR1 is incremented (51215). 5121?)
.

The imprinting head 201 is positioned by repeating this process until CNTR2 and CNTR1 match.

(3) Time/Page Bitmap Development Routine FIG. 18 shows the time/page bitmap development routine (5102) called within the main routine of the imprinting CPU 21.
1) is a flowchart.

Time Data> In step 31301, it is determined whether or not there is a change in the time data as imprint data.

As a result, if there is a change in time data (51301;
YES) imports time data from the timer IC (5
1303), expand the time data into character string data (
S1305). Furthermore, convert the time data expanded into a character string to bitmap data (51307), and read the time data reporter position from the internal variable TP (5130).
9) Rewrite the imprint data area (S13)
11).

<Page Data> In step 51313, it is determined whether there is any change in the page data as imprint data.

As a result, if there is a change in the page data (S1313
:YES), the process proceeds to step 51315, and first, through the processing in steps 51315 to 31323, data is substituted into the variable number of two pages.

That is, it is determined whether the mode is panning mode,
If it is not the panning mode (S l 315; No), the page number data is imported (see S1317:5215). Also, if you are in panning mode (51315:
YES), it is further determined whether it is the start of each round of panning 51319), and if it is the start of panning (St319; YES), the total number of pages is assigned to the variable: number of pages. (See S1321:51009).

On the other hand, if the panning shot has not started (S1319; NO), the process advances to step 51322a, and the imprint side JAM flag is determined. As a result, if the JA and M flags on the imprint side are not set (31322a; No), the data of variable: page number is decremented (51323
). Also, in step 51322a, the imprint side JA
If the M flag is set, i.e., this is the first copy after JAM reset, step 5132
Proceed to step 2b, and assign a value obtained by adding the value "1" to "Number of M pages to J" to the variable Nibage number (S1322b: 5
1016c).

In step 51325, the page number data imported as described above is expanded into a character string, and the page number data expanded into the character string is further converted into bitmap data (S1327). The page number data entry position is read from 51329), and the imprint data area is rewritten (31331).

After the above processing, the process returns to the main routine.

Note that it is also possible to control the time data so that it does not change within a series of copy operations.

(4) Image area interrupt routine Figure 19 shows the copying timer interrupt routine (Figure 13)
The imprinting CPU
This is an interrupt service routine executed by 21.

When the CPU 21 receives the interrupt request signal from the CPU 22, it interrupts the process that is being executed and moves the process to the main interrupt service routine.

First, each register is saved (S1401).

This is to restart the interrupted process after the main interrupt process is finished.

Next, the data imprinting LED of the imprinting head 201
All LED elements of the array 203 are turned off (514
03).

Also, timer T1 controlled by the timer IC is started (51405). The set value t1 of the timer Tl is set to the time required for the photosensitive drum 2 to rotate from the image leading edge position to the data imprinting start position.

Note that the timer IC controls CPU2 when the timer count ends.
1, generates a hardware interrupt request signal. Further, the CPU 21 that has received the timer interrupt request signal starts a timer interrupt routine to be described later.

After the above processing is completed, each register is restored (S1407
), this routine ends and returns to the process at the time of interruption.

(5) Timer interrupt routine FIG. 20 is a flowchart showing the timer interrupt routine.

The timer interrupt routine responds to the interrupt request signal generated by the timer IC at the end of the timer Tl that starts in the above image area interrupt routine or the timers T2, T3, and T4 that start in this timer interrupt routine. Accordingly, CP
This is an interrupt service routine executed at U21.

That is, when the CPU 21 receives the interrupt request signal from the timer fc, it interrupts the process that is being executed and moves the process to the main interrupt service routine.

First, each register is saved (S1501).

This is to restart the interrupted process after the main interrupt process is finished.

Next, it is determined whether the output of the imprint data (output to the shift register) has been completed (Sl 503).

If it is determined in step 51503 that data output has not been completed, the charger 202 of the imprinting head 201 is in the OFF state (31505; NO = if the interrupt is due to the end of timer T1) Provided that,
Proceeding to step 51515, the charging charger 202 is turned on and all LED elements of the data imprinting LED array 203 are turned on (51517). Furthermore, the timer T2 is started (S1519>. As a result, the charge removal by the LED array 203 is executed until the timer T2 ends. This is set to a value sufficient to avoid data writing (see FIG. 21).

Thereafter, the first line of imprint data (one-dot length ON/OFF control data for each LED element) is output to the shift register in the imprint head 201 (51521).

After the above processing is completed, each register is restored (S1535
), this routine ends and returns to the process at the time of interruption.

Next, when this routine is executed when the timer T2 ends (that is, when the static electricity removal from the unstable part at the time of startup of the charger 202 is completed), step 51503.
From step 51505, the process moves to step 5I507, where a latch pulse is output to the shift register. As a result, the ON10 FF control signal is output from the shift register to the driver of the LED array 203.

Also, timer T3 is started (Sl 509).

The set value t3 of the timer T3 is set to a time corresponding to the length of one dot of the dot matrix font. That is, when the timer T3 ends, a timer interrupt for the next line occurs.

In step 51511, it is determined whether the output to the shift register has been completed up to the last line of font data.

If the data output has not been completed (S1511; NO), the next line of font data is output to the shift register (S1513), the process advances to step 51535, each register is restored, and this routine ends. , returns to the process at the time of interruption.

Next, when this routine is executed at the end of timer T3 (that is, when data imprinting is being executed continuously), steps 51503, 51505, 51507, 51
Processes 509, 51511, 51513, and 51535 are repeatedly executed.

If it is determined in step 51511 that the data output has been completed, there is no data, so proceed directly to step 51535, restore each register, end this routine, and process the interruption. Return to.

When the beans fall> At step 51503, is the data output?'? ', the charger 202 of the imprint head 201 is in the ON state (51523; YES=
If the interrupt is caused by the end of the final timer T3), the process advances to step 51525, where all the LED elements of the data imprinting LED array 203 are turned on, and the charger 202 is turned off (31527).

Furthermore, timer T4 is started. As a result, the LED array 203 performs static elimination until the timer T4 expires. The set value t4 of the timer T4 is set to a value sufficient to eliminate static electricity from the unstable portion when the charger 202 falls (see FIG. 21).

After the above processing is completed, each register is restored (S1535
), this routine ends and returns to the process at the time of interruption.

Next, when this routine is executed when the timer T4 ends (that is, when the charge removal from the unstable part at the time of rising and falling of the charger 202 is completed), step 51503 is executed.
- Processing moves from step 51523 to step 51531,
All LED elements are turned off, timer counting is stopped (S1533), and timer interrupts are masked.

The timer interrupt process is executed as described above.

Note that each of the timers T2, T3, and T4 is controlled by a timer IC similarly to the timer TI.

(6) Communication interrupt routine FIG. 22 shows the communication routine (S7) of the host CPU 22.
This is an interrupt service routine that is executed by the imprinting CPU 21 in response to a data communication interrupt request signal sent by the CPU 21.

When the imprint control CPU 21 receives the communication interrupt request signal, it interrupts the processing that has been executed up to that point and transfers control to this routine.

First, after the interrupt processing is completed, each register is saved so that there is no problem when returning to the processing before the interrupt (S1601).

Next, it is determined whether a communication error has occurred during data communication (51603), and if a communication error has occurred (S1
603; No), the process advances to 51621 and error processing is performed.

On the other hand, if no communication error has occurred (S1603;
If YES), it is determined whether the sent data is imprint data (S1605).

As a result, if the received data is imprint data (S1605; YES), the data is stored in the imprint data buffer (S1607). Also, when the final data of the imprint data is received (S1609; Y
ES), a request flag indicating that the imprint data has changed is set (31611).

On the other hand, if it is determined in step 51605 that the data is not imprint data (51605: No), the process proceeds to step 51613, and it is determined whether the data is data indicating the imprint position (S1613 ).

As a result of the determination, if the received data is data indicating the imprinting position (S1613; YES), the received position data is used to control the number of steps of the stepping motor 204 for controlling the positioning of the imprinting head 201. 51615) and stores the converted data in step counter CNTR2 (51617).

Note that if the data sent from the CPU 22 is neither imprint data nor imprint position data (S160
5; No and 51613; N0), step 51
The process advances to step 619 to process other data.

In addition, in the above, the imprint data is transferred to the boss) CPU.
It is assumed that on the 22 side, the presence or absence of imprinting of time and page data is encoded and sent as serial data.

As described above, the processing by the control CPU of this copying machine is executed.

Note that the above control describes the case where the page number is decremented from the initial value (e.g. "total number of pages"), but it is also possible to increment the page number from the initial value (e.g. "1") using the same method. be.
