〔Example〕

 The present invention will be described below with reference to preferred embodiments.

FIG. 1 is a diagram showing the structure of a copying apparatus to which the present invention is applied. The copying apparatus comprises a reader 10 for reading a document image and a printer 14 for recording an image on a recording sheet. Document feeder (ADF) 10-1,
It has a double-sided unit 14-1 for feeding the image-recorded recording material to the printer and a sorter 13 for collating the image-recorded recording material.

A CCD line sensor in which a plurality of light receiving elements are arranged in a line for reading image information of an original 302 placed on a platen 301 made of a glass plate or the like of the reader 10 by an automatic paper feed by the ADF 10-1 An image pickup device (CCD) 303 such as is used. The illumination light from the light source 304 is the original 3
The light is reflected on the 02 surface and is imaged on the CCD 303 by the lens 308 via the mirrors 305, 306 and 307. The light source 304, the mirror 305, and the mirrors 306, 307 are 2: 1 in order to scan the entire area of the original.
It is designed to move back and forth on the rail 310 at a relative speed of. The optical unit composed of the mirrors 305, 306, 307 and the light source 304 moves at a constant speed while being PLL controlled by the DC servomotor 309. This moving speed is 90 mm / sec to 360 mm / sec depending on the reading magnification on the outward path from left to right in the figure.
Variable up to sec, always 630 mm / s on the return path from right to left
ec.

The moving direction of this optical unit is called the sub-scanning direction, and the direction substantially orthogonal to this sub-scanning direction is called the main scanning direction. The light receiving elements of the CCD 303 are arranged in this main scanning direction,
While scanning the original on each main scanning line by the CCD 303 at a resolution of 400 dots / inch, the optical unit is moved forward from the left end to the right end, and then moved back to the left end again to complete one scanning. The image read by the CCD 303 is serially output as a digital image signal of 1 or 0 indicating the image density.

Next, the operation of the ADF 10-1 for automatically feeding a document onto the platen 301 of the reader 10 will be described. The ADF 10-1 has an editor 14 to be described later for setting various image processing modes.
Two are provided.

An operator places one or a plurality of originals 302 upward on the original placing tray 311 of the ADF 10-1 of the reader 10. When the start key of the operation unit of the reader 10 is pressed by the operator, the reader 10 sends a document feeding instruction to the RDF 10-1, and the ADF 10-1 causes the separation belt 31
One of the lowermost originals on the original placing tray 311 is separated by 2 and is further conveyed onto the platen 301 by the conveyor belt 314 through the conveyor via the conveyor roller 313. The document is read in this state.

When the number of readings set by the operator is completed, the conveyance belt 314 is rotated in the reverse direction, the original is moved toward the conveyance rollers 320 and 319 by the deflection cam 315, and the discharge tray 3 is ejected.
Ejected on 16. The original is placed on a platen 30 by a timing pulse generator (not shown) attached so as to generate a pulse in synchronization with a paper detection sensor (not shown, but including 321) attached to the paper path and a roller drive system.
It is well known that the control is performed so as to stop accurately on 1.

When multiple originals are placed on the original placing tray 311, the next original on the tray 311 is ejected from the platen 301 after the reading operation for the original fed to the platen 301 is completed. The sheet feeding operation is performed, and the reading operation for a plurality of originals is automatically continuously performed until there are no more originals on the tray 311. A sensor 318 is provided to detect the presence / absence of a document on the tray 311.

Next, the operation of the printer 14 for recording an image on recording paper based on the image signal output by the document reading operation by the reader 10 will be described.

The printer 14 starts rotation of each part of the printer instructed to start by communication from the reader 10 and driving of various high voltage parts. When the predetermined pre-preparation operation is completed, the paper feed start signal from the reader 10 causes the designated stage (upper stage cassette 402, lower stage 403,
Start recording paper feeding from one of the paper decks 404). When the recording paper reaches the registration roller 405, the recording paper is temporarily stopped, and the latent image is formed on the photosensitive drum 400 by the laser light modulated based on the image signal from the reader 10 generated from the laser generator 401. Refeed.

The latent image on the drum 400 is developed by an electrophotographic technique, which is a well-known technique, and the developed image is transferred onto recording paper fed from a designated stage, and the recording paper is conveyed to a fixing unit 407 by a fixing unit 407. Let it pass. As a result, an image is recorded on the first surface of the recording paper.

If double-sided recording or multiplex recording is selected, the deflection cam 408 conveys the recording paper to the double-sided unit 14-1 side. The double-sided unit 14-1 is for reversing the recording paper through the conveying path 412 in the case of double-sided recording, and for guiding it to the photosensitive drum 400 of the printer 14 again without being reversed through the conveying path 415 by the deflection cam 411 in the case of multiplex recording. Things
The recording paper in the double-sided unit 14-1 is fed by the transport rollers 413,
Alternatively, it is loaded on the intermediate tray 414 by 416. The required number of sheets of recording paper with the image recorded on the first side are in the intermediate tray 414.
When the sheets are stacked on the sheet, the sheet is conveyed one by one from the intermediate tray 414 by the conveying roller 413 according to the second surface copy start instruction from the reader 10 and reaches the registration roller 405 through the conveying roller 417. Then, the image formed on the drum 400 is transferred in the same manner as the first surface, and is discharged to the sorter 13 described later through the fixing device 407 and the deflection cam 408, the conveying rollers 409 and 410. As a result, double-sided recording or multiplex recording on one side of the recording paper is performed.

On the other hand, when the double-sided recording or the multiplex recording is not selected, the recording sheet on which the image is recorded on the first side as described above is not guided to the double-sided unit 14-1 and passes through the deflection cam 408 and the conveying rollers 409 and 410. After that, it is discharged to the sorter 13.

The sorter 13 communicates with the reader 10 to notify the operation mode (one of three modes of sort, collate, and non-sort) at the start of the recording operation, so the sorter 13 is not shown attached to the transport roller 410. When the paper is detected by the sensor, it operates according to the specified operation mode. For example, in the sort mode, one recording paper bin 31
When the sheet is discharged to 7, it is shifted up by one bin and the next recording sheet is guided to the next bin. (This sorter is
The bin 317 is set to move up and down to perform collation) If the original is changed in the collate mode, the bin is up, and if it is in the non-sort mode, the bin is always discharged to the uppermost bin.

FIG. 4 is a block diagram showing the circuit configuration of the control unit of the copying machine shown in FIG. 201 corresponds to the CCD 303 shown in FIG. 1 and converts the document image set on the document table 301 into an electric signal and outputs it as an image signal. Reference numeral 202 denotes an image processing circuit that performs image processing on the image signal from the CCD 201, such as a shading correction for correcting output nonuniformity and a γ correction for correcting density characteristics. 207 is an add-on display RAM that stores the code data corresponding to the character to be added-on, 208 is an add-on font ROM that outputs the dot data that represents the character corresponding to the code data, and 205 is an add-on that stores the dot data from the add-on font RAM 208 RAM, 206 is an add-on image generation circuit that controls the output of the dot data stored in the add-on RAM, and generates add-on image data to be inserted into the original image in response to the add-on start signal ADST. 203 is an image processing circuit 202. A combining circuit that combines the original image data and the add-on image data from the add-on image generation circuit 206, and 204 is a printer that performs a printing operation based on the image data from the combining circuit 203.

Further, 210 is a control unit CPU that controls the operation of each block of the reader, and controls and operates using the RAM 215, I / O 216, etc. according to the program stored in the ROM 214. The ADF 10-1, the double-sided unit 14-1, and the sorter 13 described above exchange control signals via the I / O 216.

Reference numeral 213 is an editor 142 provided on the ADF 10-1, 212 is corresponding to the operation unit 143 shown in the second illustration, 211 is a buzzer for issuing a buzzer sound to the operator, and 209 is a sub-scanning counter for counting the number of recording lines of the printer. is there.

With the above configuration, for example, image processing as shown in FIG. 5 is possible. That is, in FIG. 5, (1) to (3)
Is three originals, and five copies are made from each of the originals on one side to obtain print outputs as in (4) to (5). Further, the print output (4) of the original (1) is obtained. The MURAM 178 "Character" is combined and recorded in the lower right, and the printouts (5) and (6) of the originals (2) and (3) are combined with the MURAM 179 and MURAM 180 in the lower right. To record.

An operation procedure for obtaining the print output as shown in FIG. 5 will be described below.

First, character input by the character input surface 143 of the editor 142 will be described. It should be noted that, in FIG. 6, the liquid crystal display unit when entering characters
The display state of 123 is shown.

When the character input key 134 on the editor 142 is pressed, the screen shown in FIG. 6 (1) is displayed on the liquid crystal display 123.
The liquid crystal display unit 123 communicates with the CPU 210, and it is possible to notify the CPU 210 of the presence / absence of a key input by using the portion surrounded by the dotted line in the drawing as one key. Also, the cursor 601 is blinking at the display position where characters are input in the figure, and it is controlled so that it can be moved up, down, left and right of the screen by pressing the cursor movement key 602 that is displayed. . When an incorrect character is input, the operator moves the cursor 601 to the character for which the error was input and inputs the character again to correct the character. If clear key 603 is pressed, all characters are cleared.

Now, a method of inputting characters using the editor 142 will be described below.

The editor 142 and the CPU 201 are in serial communication,
It is possible to tell the CPU 201 which position of the digitizer 139 on the editor 142 the touch pen 138 points to. FIG. 7 shows the operation of the CPU 210 relating to character input.

When the operator points a certain position on the editor 142 with the touch pen 138 (S1), it is determined whether the point coordinate information from the editor 142 is inside the character input surface 143 (S2). If it is inside 143, the buzzer 39 is operated to notify the operator that a character has been input (S3), and a code corresponding to each character, specifically "A" → 0 "B "→ 1 ... Blank → 149 is determined and stored in the add-on display RAM 33 (S
Four). This data is reflected on the screen display of the liquid crystal display unit 123 (S5), and the cursor is normally moved to the right by one. If the current cursor position is the rightmost, the cursor is moved to the leftmost one line down. Fig. 6 (2) shows a concrete display example and add-on display corresponding to that display.
The contents of RAM are shown in FIG.

In this way, the operator can input the desired character.

Next, the count up mode using the character input mode will be described.

The count-up mode is a function of overlaying a continuous numeric string in which characters have been input on the original image information while incrementing or decrementing it as shown in, for example, FIG. 5, and it can be used for numbering or page numbering of copies.

In FIG. 6, reference numeral 604 is a count-up key for designating the count-up mode, and 605 is a count-down key for designating the count-down mode.

The operator first performs the initial value of the number (column) to be counted up or down by the same method as the above-mentioned normal character input. The state where this input is completed is shown in FIG. 6 (2). Now, after entering the number string "178", the cursor
601 is located to the right of "8".

Since the same control is performed when the count-up key 604 and the count-down key 605 are pressed, only the control when the count-up key 604 is pressed will be described here with reference to FIG.

When the count-up key 604 is pressed in the state of FIG. 6 (2) (S16), it is neither in the count-up mode nor in the countdown mode in the initial state (S17, S19),
Although the process proceeds to step S21, no operation is performed because the position of the cursor 601 is not a number.

Therefore, when setting the count-up mode or the down mode, the operator operates the cursor movement key 602 to move the cursor 601 to the position of the count-up mode or the initial value of the down numeral as shown in FIG. 6 (3).

When the count-up key 604 is pressed in the state of FIG. 6 (3), neither count-up mode nor count-down mode (S17, S19) exists, and the position of the cursor 601 is on the numeral "8" (S11). Set the mode (S22). What is the setting of the count-up mode? Specifically, the cursor stored in the add-on display RAM 207 described above.
The continuous numeric code from the position of 601 is rewritten to the count-up data (S22). In this embodiment, since the codes 0 to 149 are used as the normal character codes, the numerical codes corresponding to "0", "1" ... "9" for counting up are 150 to 159 and "0" for counting down. "1" ...
The numerical code corresponding to "9" is 160 to 169.

FIG. 8 (2) shows the contents of the add-on display RAM 207 after conversion in accordance with the count-up mode. That is, the code of the numeral "7" at the cursor position and the numeral "8" on the right side thereof are rewritten to the count-up codes "156" and "157". Since this conversion is only for the purpose of content processing, it is necessary to notify the operator of which number string is in the countup mode or the countdown mode. Add-on display RAM207 after conversion here
By using the contents of, the count up mode or the count down mode numbers are highlighted and the count up key 24 or count up key 604 is also controlled to be highlighted (S23). This state is shown in Fig. 6 (4).
, And the cursor 601 is blinking at the position where “7” is highlighted. On the contrary, in order to cancel the count-up mode, by pressing the count-up key 604 which is highlighted again, the count-up mode is canceled (S20), and the numbers and the count-up key are also highlighted. .

After the setting of the count-up down mode is completed in this way, the operator operates the start key 101 to start the copying operation. The control procedure of the CPU 210 during this copying operation will be described with reference to FIG.

The character string entered as described above is the add-on display RAM2.
It is stored as a code in 07 and does not have the character as image information.

Therefore, when the start key 101 is operated by the operator (S31), the CPU 210 first determines whether the add-on counter up or down mode is selected (S3).
2) If the mode is selected, the font information corresponding to the code of the add-on display RAM 207 is read from the add-on font ROM 208 and expanded in the add-on RAM 205 (S33). At this time, only the font information of the input characters is arranged in order in the add-on RAM 205, and even if the add-on RAM 205 is directly read, it is not image information. Therefore, the CPU 210 sets parameters such as character size, main scanning direction position information, sub-scanning direction position information, etc. to the add-on image generation circuit 206, and when the add-on RAM 205 is read through the add-on image generation circuit 206, it becomes image information. To do.

These parameters and the like may be fixedly set in advance, or may be set using the operation unit 143 and the editor 142. After the font information is expanded in the add-on RAM 205 and the parameters are set in the add-on image generation circuit 206 in this way, the CPU 210 determines whether or not copying is performed using the ADF 10-1 (S34).

Original copy tray 3 for copying using ADF10-1
Documents are fed from 11 to the platen 301 (S35), and then
The image forming operation is started, the document is repeatedly read a set number of times by the reader 10, the CCD 201 performs photoelectric conversion, the image processing circuit 202 performs image processing of the shade correction and γ correction, and the image data of the character string from the add-on image generation circuit 206. And the original image data are combined by the combining circuit 203 and output to the printer 204 to obtain the required number of printouts (S36).

On the other hand, when the ADF 10-1 is not used, the image forming operation is repeatedly performed for the required number of sheets without operating the ADF 10-1 (S3
6).

When the image forming operation is completed by the number set by the ten keys 105 (S37), the CPU 210 determines whether or not the ADF is used (S3).
8).

When using the ADF, first, it is judged whether or not there is another document on the document tray 311 (S39), and if it exists, whether or not the add-on count up or down mode is set is determined. If it is determined (S40) and the mode is set, the count-up code or count-down code of the add-on display RAM 207 is incremented or decremented by 1 in accordance with the count-up or count-down mode, and the code is updated (S41). Then proceed to step S32.
Similar image formation is performed on the next original placed on the original placing tray of the ADF 10-1.

As shown in FIG. 6, when the ADF is used, if the “MURAM 178” is set as the initial character and the add-on count up mode is set, the ADF10
-1 is added to each of the three originals shown in FIGS. 5 (1) to (3) that are automatically fed sequentially, the image is added until the originals are no longer present on the original tray 311 while adding the code in the add-on display RAM 207. The formation is continued to obtain the print output as shown in FIGS. 5 (4) to 5 (6).

In the case of copying without using the ADF10-1, after completion of copying the required number of sheets (S37), it is determined whether the add-on count up or down mode is set (S4).
2) If the mode is set, add-on display RAM 207 is added according to the count up or count down mode.
The count-up code or count-down code of 1 is added or subtracted by 1 to update the code (S43). Then, the image forming operation is stopped, and the operation of the next start key 101 by the operator is awaited.

In this way, if the ADF 10-1 is not used and the required number of copies for one original set on the platen 301 by the operator is completed, the add-on display RA
Update the code of M207, add 1 increment or decrement to the original set by the operator, stop by the state where print output is possible, and press the start key 10
If 1 is pressed, add-on display RAM 20 being updated
The number 7 is combined with the original image and printed.

As described above, when ADF10-1 is not used,
For example, the operator manually sets the documents (1) to (3) shown in the fifth illustration on the platen 301, and the start key 101 is set for each document.
The outputs of FIGS. 5 (4) to 5 (6) are obtained by operating.

As described above, by automatically adding or subtracting the numerical information to be combined and recorded in the original image, the operator does not have to set the numerical information for each original, and the desired numerical information can be displayed. The composition can be easily executed.

In this embodiment, the copying apparatus that photoelectrically reads the original is described, but the present invention is not limited to this and can be applied to a copying apparatus that performs a copying operation by directly projecting the original image on the photosensitive member. In addition to the example in which the numerical data to be combined is added or subtracted one by one, the number of additions or the number of subtractions can be arbitrarily set.

〔effect〕

As described above, according to the present invention, it is possible to combine character information including a desired number and character information in a document image, and to update only a desired number among a plurality of numbers to be combined, The application of synthetic recording can be expanded.
