Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a copying machine with a data imprinting function that can imprint page numbers (and total page numbers).

The copying machine of the present invention does not imprint page numbers (and total page numbers) if it cannot automatically count the number of original sheets before imprinting page numbers (and total page numbers). .

[Conventional technology]

(1) A copying machine has been proposed or provided (Japanese Patent Publication No. 59-52811) that can imprint data such as date, page number, etc. on the copied image when copying the 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 imprinted on the area.

In addition, in the above, when imprinting page number data, it is generally possible to imprint the total page along with the current page, such as **/## (*: current page, #: total page). It is being done.

(2) Original circulation + f & feeding device (RD) 1; hereinafter referred to as RD
(abbreviated as H) has been proposed or provided (Japanese Unexamined Patent Publication No. 5
5-98762).

This device is a device that enables document copying in a panning mode, and is used by being set on the document table of a copying machine.

The panning mode is a mode in which an image is scanned by moving the document on the document table while the scanning system of the copying machine is fixed. This was devised in view of the fact that there is loss time due to scanner return in normal copying mode, and to eliminate this loss time and thereby achieve higher speeds.

Furthermore, when using RDH, the number of original documents is generally counted. This is because it is necessary to detect the end timing of the copying operation in the panning mode.

Nafu, RDH is in ADF mode (original automatic feeding mode:
A mode in which the original is automatically fed onto the document glass, positioned at a fixed position on the document glass, the copying machine's scanning system is driven to scan the image, and then the document is ejected from the document glass.) It can also be used in In this mode, counting the number of originals is
Since it is not necessary, it is not normally done.

In addition, by opening the RDI (original transport section),
It is configured so that manual document setting is also possible.

[Problem that the invention seeks to solve]

As described above, in order to imprint the total number of pages together with the current page on a copy image, data on the total number of original sheets is required.

Additionally, when using an automatic document feeder, copies are often made from the last page of the document, and in such cases, data on the total number of originals is required in advance even if only the current page is to be imprinted. It is.

For this reason, conventionally, the total number of pages has been entered manually using a numeric keypad or the like on an operation panel. In other words, conventionally, it was necessary to manually count the number of original sheets.

The present applicant has filed an invention for solving this problem on the same date as the present application. The application filed on the same date is RDH
By focusing on the original number counting function of , the number of original sheets is automatically counted before the start of the copying operation, thereby eliminating the need for human labor to calculate the total number of pages.

However, RDH does not count the number of original sheets before the copying operation.
It doesn't always run. For example, when using the RDH in ADF mode, the number of original sheets is not normally counted.

Therefore, for example, if you try to imprint a page number without inputting the total number of pages or counting the number of original sheets when the DF mode is set on RDH, the page to be imprinted will Miscopy occurs because the data is not finalized.

The present invention is intended to deal with such a case.

[Means and effects for solving the problems] The present invention provides a document transporting means for feeding the document onto the document table and collecting the document from the document table, and a data copying device for imprinting data superimposed on the document image. a copying machine having: a page mode setting means for setting a page data imprinting mode in which a page number is imprinted on the original image; and a counting mode setting means for setting a counting mode in which the number of original sheets is counted. , a data management means that calculates and sets page data for imprinting based on the counting results, when the page data imprinting mode is selected and the counting mode is not set,
This is a copying machine with a data imprinting function, which has a page mode canceling means for canceling the page data imprinting mode.

According to the present invention, after setting the page data imprinting mode, if the counting mode (this mode is set in conjunction with the panning mode, for example) is not set, the page data imprinting mode is canceled. .

Therefore, according to the present invention, the occurrence of copy mistakes due to undetermined page data to be imprinted can be prevented.

Below, margin 〔Example〕 The present invention will be explained in detail below.

(Overall explanation of the mechanism) Figure 1 shows a copying machine and a document circulation conveyance device (
FIG. 2 is a schematic diagram showing the configuration of RDH.

The illustrated copying machine has an optical system 101 in the upper stage and an image forming unit 1 in the middle stage.
02, a configuration in which a paper refeeding unit 103 is arranged at the lower stage, and a paper feeding unit 104 is arranged at the lowest stage,
Further, on the document table 16, a document circulation conveyance device (RD
H) 400 is set.

(1) Optical system 101 The optical system 101 is configured to operate an original set on the original table glass 16 (original set is a manual or RDH ADF).
mode) or the document moving on the document table 16 (the document movement for scanning is performed in the RDH panning mode), and the reflected light from the document image is transferred to the image forming unit 102. The photosensitive drum 2 is guided to the photosensitive drum 2, and an image is formed on the surface of the photosensitive drum 2.

The optical system 101 includes an exposure lamp 10, reflecting mirrors 11a, 11
b% I IC511d% and lens 12.

In normal mode (modes other than panning mode; panning mode will be explained later), when scanning a document,
The exposure lamp 10 and the reflecting mirror 11a move at a speed of V/N (V: peripheral speed of the photosensitive drum 2, N: copying magnification), and the reflecting mirrors 11b and IIC move at a speed of V/2N, respectively, from the document table 16. It moves back and forth along the bottom surface of the document to expose and scan the document.

On the other hand, under the panning mode using RDH400, the exposure lamp 10, reflector 11a, and reflectors 11b-11C
, is held fixed at the reference position. 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 imaging position is corrected by adjusting the angle of the reflecting mirror lld.

(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 unit 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, an electrostatic charger 6, a data imprinting unit 200, A developing device 3a (accommodating black toner in this embodiment), a developing device 3b (accommodating red toner in this embodiment), a transfer charger 5as, a separation charger 5b, a cleaning device 4, and a conveyor for conveying the copied copy paper. It has a belt 8 and a fixing device 9 that fixes the toner image on the transported paper. Note that the data imprinting unit 200 will be described in detail later.

Further, 13 is a photosensitive drum 20 for feeding the copy paper.
The photosensitive drum 2 is rotated at a predetermined timing in synchronization with the rotation.
- A pair of imming rollers are conveyed between the transfer charger 5a, while 14 and 15 are a pair of rollers for discharging the copy paper from the image forming section 102 for the image fixing method.

Note that switching between ejecting the copy paper ejected from the image forming unit 1102 onto the ejecting tray 36 or ejecting it into a refeeding tray 58, which will be described later, is a switching operation operated by a solenoid (not shown). This is carried out by lever 41.

(3) Paper refeeding unit 103 The paper refeeding unit 103 is capable of composite copying (copying in which a composite image is formed on the same side of the paper by two consecutive image forming processes), and double-sided copying (copying that forms a composite image on the same side of paper by two consecutive image forming processes). It is used for copying (copying) in which images are formed on the front and back sides of paper through multiple image forming processes.

That is, the copy paper on which the image has been transferred and fixed on one side (first side) passes through the paper passage path 530 during composite copying, and through the paper passage 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 when double-sided copying is performed. is the image forming surface (
so that the first surface) faces the transfer charger 5a side,
Each will be done.

(4) Paper Feeding Unit 104 The paper feeding unit 104 has an upper paper tray 42 and a lower paper feeding tray 43 that accommodate sheets of 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 unit 102, and is fed by a predetermined timing signal from the optical system 101 or the RDH 400. and in synchronization with the rotation of the photoreceptor drum 2.
- The image is transferred between the transfer chargers 5a and subjected to image transfer.

(5) Document circulation device (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. Conveyed on the table 16 to the left in the figure at a constant speed,
Thereafter, the document is collected from the left side in the figure again onto the document tray 412, and is used by being set on the document table 16 of the copying machine. Note that the RDH 400 can be used in a panning mode and a non-panning mode (to-DF 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 transferred to the conveyor belt at a predetermined timing (1) In the panning mode, the document is placed at a predetermined timing at the entrance to the document table (the right end side in the figure). Due to the frictional force of 423, -at a constant speed, the document table 1
6 and is conveyed to the left in the figure while being exposed and scanned.

At this time, as described above, the exposure lamp 10 and the reflecting mirrors 11a-11b-tic 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 interval between sheets fed from the paper feed unit is extremely narrow, so by the time the final document is detected, more sheets than the required number have already been fed from the paper feed unit. In order to prevent this, it is necessary to know the number of originals in advance. Therefore, the number of originals is counted by skipping the originals before copying starts.

When counting the number of originals, the first original to be collected (=first fed original; first original) is placed in the tray 41.
Instead of being collected directly on top of the topmost original (final original) set in the first original and the final original, a lever 410 for detecting the final original is interposed between the first original and the final original. It will be done.

That is, when a document is first set on the tray 412, the tip of the lever 410 is placed on the top layer of the document (final thickness M). 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 4111'. As a result, it is detected that the final document has been fed.

Detection of the feeding of the final original is necessary for counting the number of originals, separating multiple copies from one original (hereinafter referred to as multi-copying), stopping the copying operation, etc., as will be described later. This data is provided as detailed data.

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

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, (ii) non-panning mode (mode in which RDH is used as an automatic document feeder (ADF); ADF mode)
In some cases, the document that has passed the position of the paper feed detection sensor 421 is first 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/H, and the reflecting mirror 11a is
b and 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 transport unit 405 can be opened upward on the operator side, and the document table 16 can be
The structure is such that an 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 a driving pulley 211 by a stepping motor 204, and using a belt 20 stretched between the driving pulley 211 and the subordinate pulley 211.
This is done by rotating 5.

That is, as shown in the figure, a data imprinting device 20 in which an LED array 203 and a charger 202 are integrated
1 is fixed on the belt 205. Therefore, as the belt 2050 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 CNTR1 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 the head is easily moved. By employing an IJ mechanism, data can be imprinted onto any arbitrary position on the photosensitive drum 2. However, the present invention does not limit the length of the data imprinting head 201. 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, on the operation panel, there is a numeric keypad group 315 for entering numerical values such as the number of copies or total number of pages, a copy start key 308 for instructing the start of a copy operation,
A display section 319 that displays numerical values such as the number of copies or total number of pages in segments, an imprint key 302 that instructs setting of the date and/or page imprint mode, and a display that indicates that the date imprint mode has been set. date L

ED316-318, entry space 307 for entering colors corresponding to color specification keys 312-314;
A liquid crystal display section 330 and the like for displaying various messages related to the page mode are arranged.

Note that in the above, the data printing color refers to the printing color of imprint data.

Furthermore, when the total number of pages is entered manually, 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.

The host CPU 22 receives 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.). , signals from various sensor groups (not shown) placed 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, the imprint CPTJ21 has the CPU2

S19).

In step S21, other processing (processing other than the above executed by the CPU 22, detailed description because it is not directly related to the gist of the present invention) is executed.

Thereafter, in step 323, the process waits for the routine timer to end, returns to S5, and repeats the process.

In step 51003, 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 data imprinting mode is not in effect (S1003; No), the image area (S1025), and returns to 51003.

On the other hand, if it is determined in step 51003 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 (S1005; No), step 31007

Proceed to step 7.

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 (S 1005 ; YES), processing corresponding to the change is executed.

That is, first, the execution of the copy operation is prohibited (51007).
, takes in the total page number data transmitted from the host CPU 22 (3100, 9). Next, bitmap development of the standard data for imprinting is executed (31011), and a motor control routine for controlling the position of the data imprinting head 201 is executed (51013). After that, the copy operation is permitted (St015).

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

(B) Detailed explanation of each subroutine step 1> Subroutine of the host CPU 22 (1) Analysis routine (S9) 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 imprint page numbers, ! A total page mode check routine (S103) that manages the human power for the number of pages, a page mode reset check routine (S105) that resets the page data imprinting mode when the specified number of copies have been completed, and a page data imprinting mode. A page mode JAM processing routine (S107) for managing page data after the JAM processing and other analysis processing are executed.

The details of the page count routine (S101), m page mode check routine (S103), and page mode reset check routine (S105) are as follows.
It is described below.

Page Count Routine (Slot)> 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 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, page LED3 Q4 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 (S20
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
If 304 is ON, that is, if the mode is page data imprinting mode (5201; YES), the process advances to step 8203 and checks whether or not the total number of 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 input or by counting the number of originals when using RDH (described later) (S203).

As a result of the determination in step 5203, if the total number of pages has changed (S203; YES), after assigning the changed total number of pages to the internal variable: PAGE (5213), the process proceeds to step 5215, and the PAGE data is changed. Execute the transfer process.

On the other hand, if it is determined in step 5203 that there is no change in the total number of pages (S203; No), the RDH panning mode is not in effect (S205; No), and the copy paper has passed the timing roller 13. (S20T; YES), and the condition is that the set number of copies of the document on the document table 16 is completed with the paper that has passed the timing roller at that time (S209;
YES), the data of the internal variable PAGE is decremented (S211), and the process proceeds to step S215.
Executes 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.

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 turned off.
FF and return.

On the other hand, as a result of the determination in step 5303, if the total page input completed flag is 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 (S
305; No) displays display pattern a (see FIG. 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 analysis routine.

As a result of the determination in step 5305, if it is determined that the mode is to use RDH (S305.YES), the process proceeds to step 5307, and it is determined whether or not the mode is to use RDH in panning mode.

Judgment result: <3307 in panning mode; YE
S) In the present embodiment, prior to the copying operation, the document blank feed is performed to count the number of document sheets, so that manual effort is not required to calculate 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 8307 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. 5313, display pattern d (see FIG. 14) is displayed on the liquid crystal display 330 to instruct selection of panning mode.
), return to the parsing 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 you want to count the number of original sheets, it is determined whether or not the mode is for counting the number of original sheets. If not, the LED 304 is turned off and a display instructing you to select a mode for counting the number of original sheets is displayed. Just do it. However, in that case, the basic concept is the same as above.

Page Mode Reset (S105)> FIG. 9 is a flowchart showing the page mode reset check routine called in 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
403).

As a result, if it is in panning mode (S403; Y
ES) is conditional on the completion of multi-copying by panning, that is, the completion of copying the total number of copies (&! Number of pages x number of copies) (S405; YES), and when the mode is not panning (S403; NO), The total number of pages input flag is set (S407; YES), and the internal variable: PAGE is O (S40
9: YES), proceed to step 3411.

If the above conditions are met, that is, if it is recognized that the set series of copying processes have been completed in page mode, the page LED will be turned on to reset the page mode.
304 to 0FFI (S411), and to indicate to the operator that the page mode has been reset, the display pattern e(
(see FIG. 14) is displayed (S413).

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

(2) Key manual processing routine (S15) FIG. 10 is a flowchart of the key manual processing routine (S15) called within the main routine of the host CPU 22.

Flag Management Steps 5501 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, when the ON edge of the imprint key 302 is detected (S501: YES) +t, date L E D3
03, Determine page LED 304 L (S503.550
5.5515), the date imprint flag and page imprint flag are set or reset according to the results.

For example, date LED 303 = OFF (S 503
: YES), page LED304=OFF (S50
5; If YES), set the date flag 550
7), reset the page flag (S509).

Similarly, date LED 303 = OFF (S 503;
YES), page LED304=ON (S505
; NO), set the date flag and page flag (3511.5513).

Similarly, date LED 303 = ON (S 503 ;N
o), page LED 304 = OFF (S515; YE
S), reset the 84 inch flag 5517)
, sets a page flag (S519).

Also, date LED 303 = ON (3503; NO),
If the page LED 304 is ON (S505; NO), the date flag and page flag are reset (S521.5523).

In steps 8525-5531, insert-1--
Corresponding to the ON edge of 305, if insert mode is set at the time of the ON edge (3527; YE
S) should reset the insert flag 5529),
On the other hand, if insert mode is not set (S5
27; No) sets the insert flag (35
31) 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 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 (353
3; YES) sets the color flag (S535
). On the other hand, if the ON edge of any color select key is not detected (S533; 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 3539, 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 imprint unit 200 is not attached (5547; No), the date LED 303 is turned off (S551).

In step 3553, the page flag is determined.

As a result, if the page flag is set (S553;
YES) is on the condition that the imprint unit 700 is installed in the copying machine (3555; YES), 5
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; YE, S), the page imprint mode is set. In other words, if it is determined whether or not to use RDH (5559), if RDH is not used (
If S559; No) requires human effort for the total number of pages, an insert flag is set (5561). Furthermore, since the total page data is unconfirmed, the total page number input completed flag is reset (S563). Then page L
The ED 304 is turned on (S565), thereby setting the page imprint mode.

Note that if the page flag is off in step 5553 (S553; No>) or if the imprint unit 200 is not installed in step 5555 (355
5; No) means that page data cannot be imprinted (imprinted), so the page LED 304 is turned off (S567) and the page imprint mode is canceled.

In step 8569, the insert flag is determined.

If the insert flag is set (S569; YES
) should determine the page LED 304 (5573), ON
Under the condition that it is (S573: No), the insert LED 306 is turned on (3579). insert L
ED306 is an LED that indicates the selected state of insert mode.

On the other hand, if the insert flag is off in step 5569 (S569; No), or the page LED 30
4 is OFF (8573; YES), the insert LED 306 is turned OFF (S575). This cancels the insert mode.

In step 8583, the color flag is determined.

If the color flag is set (S583; YES), the color developing device corresponding to the selected color is installed in the copying machine (3585; YES).
S), Variable: Set and store the selected color in the copy color 3587), Color selection LED3
After setting all 16 to 318 to 0FFt (3589), the color selection display LED corresponding to the selected color
is turned on (S591).

In step 5593, the numeric keypad flag is determined.

If the numeric keypad flag is set (3593; YES)
The process 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 (3603).
.

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 (S595.YES).
S597; YES), the input numerical value is set and stored as the total number of pages (5599), and the total number of pages method flag is set (S601).

Thereafter, the numerical value input and stored as the total number of 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 (S
607>.

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 or not to use RDH, and if so, whether or not to use RDH in panning mode (S 609.3611), and as a result, when using RDH in panning mode ( S609; YES, and 3
611; YES) sets the 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) is RD)(
The count flag is lowered (S615).

Thereafter, a copy start flag is set (3617).

Note that, as 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.

Steps 8619 to 8623 are steps 5501
This is a step that collectively shows the processing for inputting any operation keys not mentioned in 3617.

That is, if the ON edge of another key is detected (S
619; YES), the insert mode is not set (S621; YES), and the process corresponding to the detected key force is executed (S623).
.

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 (S19) 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.

In step 5701, the RDH count flag is determined (3701).

If the RDH count flag is set (S701; N
o) executes the RDH count routine (S713
). As will be described later, the RDH count routine is a routine for blank-feeding originals and counting the number of originals prior to a copying operation.

On the other hand, if the RDH count flag is off in step 5701 (S701; YES), this means that RDH is not used, or RDH is used in ADF mode, or the number of originals is counted in the RDH count routine. is completed. in this case,
The process advances to step 5703 and the page LED 304 is determined.

When in page imprint mode (3703; YES)
On the condition that the total page number input flag is set (S705; YES), the timer count variable:
tl is set to 0 (5707), and the copying timer interrupt timer is activated (S709). As a result, "copying timer interrupt processing", which will be described later, is activated and copy operation processing is started. In addition, the copy start flag is lowered (5711), and the liquid crystal display 330 (14th
(see figure) is turned off (5715).

In addition, in 5705, if the total page number input flag is off, in other words, if RDH is not used or if RDH is used in ADF mode, the page data imprint mode is selected. However, the total number of pages has not been entered (S705;
No.) is displayed on the LCD display 330 on the operation panel.
Please display display pattern C (see Figure 14).5717)
, and also lowers the copy start flag (S719).
, disables copy start.

Note that in step 5703, the page LED 304
is OFF, step 5705 is jumped and steps 5707 to 5715 are executed. In this case, copying without page imprinting is performed.

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

<RDH count routine (3713)> Figure 12 shows
12 is a flowchart showing an RDH count routine (S713) 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 410 and the detection sensor 411 of the RDH unit 400 (S801) .

If the end of the original is not detected (S801; No)
feeds the original (S803), and increments the original counter (S807) on condition that the passage of the trailing edge of the original is detected by the original detection sensor 421 (3805; YES).

After that, it returns to 5801 and continues until the count of all manuscripts is completed.
Repeat the processes from 801 to 5807.

Further, in step 5801, if the end of the original on the original tray 412 is detected (S801; YES)
5809), and 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 total number of pages input 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 Timer Interrupt Routine FIG. 13 shows various copy operation control routines that are processed by the host CPU 22 in response to a timer interrupt request signal from the interrupt timer IC. 3 is a flowchart of a copying timer interrupt routine. Note that the interrupt timer is set at step 570 in the copy start routine.
It is activated by 9.

First, when a timer interrupt request signal from the interrupt timer tC is manually 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 for which a timer count value is defined in advance according to various copy operation control timings: 'I'n (n is 1 corresponding to various copy operations)
2, . . . ) and the count value of the timer count variable 2t1 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 5903 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 variable 2TE, which defines the count value of the copy operation end timing, and the count value of the timer count variable: tl match (S905).

If the two match (S905; YES), the process advances to step 5907, and it is determined whether or not the series of copy operations has been completed.If the series of copy operations has been completed (S907; YES), the timer is stopped (S909). 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 (S911). For example, the timer count variable: tl is set to an appropriate value.

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

2〉 Imprint C! Subroutine (1) Bitmap Development Routine of PU 21 FIG. 16 shows the bitmap development routine (51011) called within the main routine of the imprinting CPU 21.
This is a flowchart.

First, check the request flag indicating that the content of the imprint data has changed (0: no change, 1: change, see the communication interrupt routine described below). If the request flag is off, <51101; No), the process returns to the main routine.

In step 51101, if it is determined that the -request flag is set (S1101; 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 code 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 (S1105゜YES), a predetermined time data imprinting format (e.g. ＊＊＊＊
Data is expanded according to year ** month ** day; ** hour ** minute ** second, where * is a number) (S 1117
), 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 development routine (described later) (S1121).

Further, if the read character data code is a code representing page data (51107; YES), similarly to the case of time data, a predetermined page data imprint format (in this embodiment, P.

○O/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 (511
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 (S t t t5).

Note that if the read character data code is neither a code representing time data nor a code representing page data (S1105; No and 51107.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).

Thereafter, it is determined whether bitmap conversion of all data in the imprint data buffer has been completed (31125),
If not completed (S l 125; No>), the process returns to step 51103, reads the next character in the buffer, and continues 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 (51127), 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 (S1013) FIG.
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 or not 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 CNTRI is a step counter corresponding to the current position of the imprinting head 201.

In step 51201, if CNTR2 and CNTR1 are equal (S1201; YES), the excitation of the stepping motor 204 is set to 0FFL (S1203), and the process returns to the main routine.

Meanwhile, in step 51201, CNTR2 and CNTR1
are not equal (S1201; No), step 5
Proceeding to step 1205, the excitation state of the stepping motor 204 is determined, and the excitation is turned on (S 12 (17>
, proceed to step 51209.

In step 51209, the magnitudes of CNTR2 and CNTR1 are compared. As a result, if CNTR2<CNTR1 (S1209.NO), the excitation signal of the stepping motor is set to shift the imprinting head 201 to the right (51211), and the step counter:C
Decrement NTR1 (51213>.

On the other hand, in step 51209, if CNTR2>CNTR1 (Sl 209 ; YES), the excitation signal of the stepping motor is set to shift the imprinting head 201 to the left (31215), and the step counter: CNTR1 is incremented. (S121?
).

The imprint 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 j[routine (SIQ2
1) is a flowchart.

Time Data> In step 51301, it is determined whether or not there is a change in time data as imprint data.

As a result, if there is a change in time data (Si2O3;
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 (313
11).

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

As a result, if there is a change in page data (Sl 31
3; YES), proceed to step 51315, and first,
The processing in steps 51315 to 51323 executes the assignment of data to the variable bibage number.

That is, it is determined whether the mode is panning mode,
If it is not panning mode (S1315; No),
Import page number data (see 31317:3215). Also, if the camera is in panning mode (S1315
; YES), it is further determined whether it is the start of each round of panning 51319), and if it is the start of panning (31319; YES), the total number of pages is assigned to the variable: number of pages. 51321:51009), if panning has not started (S1319; No), the variable:
The page number data is decremented (S1323).

In step 31325, the page number data imported as described above is expanded into a character string, and after converting the page number data expanded into the character string into bitmap data (S1327), from the internal variable: PP. The page number data and writer position are read out (51329), and the imprint data area is rewritten (S1331).

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)
In response to an interrupt request signal generated within the imprint CPt
This is an interrupt service routine executed by J21.

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 (31401).

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

Next, use the LED for data imprinting on the imprinting RAD 201.
All LED elements of the array 203 are turned off (S140
3).

Also, timer T1 controlled by the timer IC is started (S1405). The set value t1 of the timer T1 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 completing the above processing, restore each register (81407
), 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 TI that starts within the above image area interrupt routine or the timers T2, T3, and T4 that start within this timer interrupt routine. Accordingly, CP
Interrupt service routine executed in U21.

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

First, each register is saved (Sl 501).

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

Next, it is determined whether the output of imprint data (output to the shift register) has been completed (S1503).

If it is determined in step 51503 that the data output has not been completed, the charger 202 of the imprint head 201 is in the OFF state (Sl505: NO=if the interrupt is due to the end of timer TI) 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 (31517). Furthermore, timer T2 is started (S1519). As a result, charge removal by the LED array 203 is performed until the timer T2 ends. The set value t2 of the timer T2 is set to a value sufficient to avoid writing data into the unstable portion when the charger 202 starts up (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 radar 201 (S1521).

After the above processing is completed, each register is restored (Sl 53
5) Terminate this routine and return 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 51507, where a latch pulse is output to the shift register. As a result, the 0N10FF control signal is output from the shift register to the driver of the LED array 203.

Also, timer T3 is started (S1509). 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,
Upon completion of timer T3, a timer interrupt for the next line occurs.

In step 31511, it is determined whether the output to the shift register has been completed up to the last line of font data.

When the data output ends (S1511; No), the next line of font data is output to the shift register (
Step S1513), proceeds to step 51535, restores each register, ends this routine, and 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, 31
Processes 509, 51511, 51513, and 31535 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 31535, restore each register, end this routine, and process the interruption. Return to.

<At falling edge> If it is determined in step 51503 that the data output has ended, the charger 202 of the imprint head 201 is in the ON state (St523; YES = interruption due to the end of Saihiragi's timer T3). If the data imprinting LED array 203 is included), 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 (S1527). Furthermore, timer T4 is started. As a result, timer T
The charge elimination by the LED array 203 is executed until the end of 4. 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 at the end of timer T4 (that is, when the charge removal from the unstable part at the time of falling of the charger 202 is completed), step 51503
From step 51523, the process moves to step 51531, where all LED elements are turned off, timer counting is stopped (S l 533), 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 T1.

(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 (31603), and if a communication error has occurred (31603),
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 (51609,
If YES), 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 (S1605; No), the process advances to step 31613, and it is determined whether the data is data indicating the imprint position (31613). .

As a result of the determination, if the received data is data indicating the imprint position (31613; YES), the received position data is used as the number of steps of the stepping motor 204 for controlling the positioning of the imprint head 201. 31615) and stores the converted data in the step counter CNTR2 (31617).

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

In addition, in the above, the imprint data is stored in the host 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 in the CPU of this copying machine is executed.

In this example, the number of originals was counted using the RDH in a copying machine equipped with the RDH. , other means may also be used.

(Hereinafter referred to as margins) In this embodiment, if the page data imprint mode is selected and the panning mode is not set, the page data imprint mode is canceled. After selecting the data imprint mode,
If the panning mode is not set until a predetermined time has elapsed or a predetermined key such as a copy start key or a numeric keypad for inputting the number of copies is operated, the page data imprinting mode may be canceled.

In addition, in this embodiment, the number of original sheets is counted only in the panning mode, so when the panning mode is not set, the page data imprint mode is canceled, but only the number of original sheets is counted. A separate counting mode may be provided, and this mode may be selected even in the ADF mode.
Even in the DF mode, it is possible to count the number of original sheets and set the page data imprint mode.

〔Effect of the invention〕

As described above, the present invention has a document conveying means and a data imprinting means, and is capable of setting a page data imprinting mode and a counting mode for counting the number of original sheets, and furthermore, it is possible to set page data imprinting mode and counting mode for counting the number of original sheets. After setting the page data imprint mode, if the blank feed counting mode is not set within a predetermined time or by a predetermined key switch manually, the page data imprint mode is canceled. It's a copy machine.

As described in the embodiment, the occurrence of copy mistakes due to the page data to be imprinted being not determined is prevented.
