Next, a schematic copy process will be described with reference to FIGS.
This will be described with reference to FIG. The RDH2 has a document tray 2
01, and the original placed on the
2. It is conveyed on the contact glass 101 through the turn section 203. Then, the original is illuminated by the flash lamp 102 over the entire surface. Electric power is supplied to the power source 103 of the flash lamp 102 prior to the flash and emits light at a predetermined timing. The light reflected from the document exposes the photoconductor 107 by the first mirror 104, the through lens 105, and the second mirror 106.

The photoconductor 107 is uniformly charged by the charger 108, and forms an electrostatic latent image by exposure. The electrostatic latent image on the photoconductor 107 is removed by the eraser 109 from unnecessary charges, developed by the developing device 110, and sent to the transfer unit. The developed document image is then transferred onto a transfer paper by the transfer charger 111.

This transfer paper is used as paper feed trays 112 and 11
The sheet is fed from any one of the trays 3, 114 and the double-sided tray 124 and conveyed along the conveyance path 115.
The image is sent between the photoconductor 107 and the transfer charger 111 at the same timing as the original image on the photoconductor 107 by means of 16. Then, the transfer sheet on which the image is transferred is separated from the photoconductor 107 by the separation charger 120, and the transfer belt 11
Then, the toner passes through 7 and is fixed by the fixing device 118.

In the double-sided mode for copying on both sides of the transfer paper,
The double-sided switching claw 121 is switched to the double-sided tray 124 side, the transfer paper is sent to the double-sided tray 124 through the double-sided entrance path 123, and is temporarily stored in the double-sided tray 124. Also,
In the single-sided mode in which only one side of the transfer paper is copied, the double-sided switching claw 121 is switched to the paper discharge side, and the discharge switching claw 1
It is transported to 22. The discharge switching claw 122 has a function of switching between discharging the transfer paper to the main body tray 119 side and discharging the transfer paper to the peripheral device (finisher 4).

After the transfer paper is separated, the photoconductor 107 is destaticized by the destaticizing charger 125, and the cleaning device 126 removes the residual toner on the photoconductor 107 to prepare for the next copying. Since the photoconductor 107 has a seam, the image forming area on the belt should avoid the seam,
Each size is set to have an equal interval.

FIG. 6 shows a photoconductor 107 cut and developed at a seam.
FIG. 3 is a diagram showing the arrangement of image forming areas (segments).
5 A4 segments indicated by dashed lines, B4 indicated by broken lines
4 segments and 3 A3 segments indicated by the two-dot chain line
The individual pieces are set to be evenly spaced.

FIG. 7 is a block diagram of the image formation controller. This control unit includes a CPU 401, an output port 402,
It is composed of an input port 403 and the like. Input port 40
Various sensors are connected to 3 to input sensor signals,
A motor control circuit 404, a power pack 405, and the like are connected to the output port 402 so that the load can be controlled.

At the time of image formation, in order to avoid seams, it is necessary to determine the image formation area on the photoconductor 107 prior to image formation. Therefore, a synchronization mark is provided at a fixed distance from the seam at the end of the photoconductor 107, and the mark is detected by the mark sensor 410. To determine the image area,
It is necessary to drive the photoconductor 107 to detect this mark.

Therefore, the drive signal from the output port 402 is input to the motor control circuit 404 to drive the photoconductor drive motor 408. An encoder 409 is integrally attached to the photoconductor drive motor 408,
The number of pulses output is proportional to the moving distance of the photoconductor 107. The pulse signal is input to the motor control circuit 404, is used to rotate the photoconductor drive motor 408 at a constant speed, and is also input to the frequency divider 406 to be divided at a predetermined frequency division ratio. After that, the number is input to the CPU 401 and the number is counted. Since this value is proportional to the amount of movement of the photoconductor 107, the count value determines the image forming area.

Next, the copy sequence will be described.
When the tip of the segment reaches a predetermined position, the sequence operation starts, and the sequence control counter starts operating. This counter counts up by the pulse signal from the frequency divider 406 and is cleared when the sequence is completed. The counter starts operating and its value is CNT When the value becomes 1, output port 40
2 outputs a signal to the power pack 405, and the charger 1
08 operates to uniformly charge the photoconductor 107.

Next, the count value is CNT. When it reaches 2,
A charge start signal is input from the output port 402 to the flash power supply 103, electric charges are stored in a capacitor in the flash power supply 103 to light the flash lamp 102, and the flash signal is sent to the flash power supply 103 to turn on the flash lamp 102. Illuminate, illuminate the original set on the contact glass 101,
The photoconductor 107 is exposed. The count value of this flash signal is CNT It is output at 3.

Further, the photosensitive member 107 is rotated and the leading edge of the image is at the position of the eraser 109 (= CNT). 4), the part of the eraser 109 corresponding to the image is turned off, and the rear end of the image is at the position of the eraser 109 (= CNT). When it reaches 5), the eraser 109 is fully turned on, the excess charges on the photoconductor 107 are erased, and the electrostatic latent image is left only on the original image portion.

This electrostatic latent image is developed by the developing device 110,
For front side copying, the paper feed trays 112, 113, 11
4 is transferred to the transfer paper sent from any one of the Nos. 4 and 4 in the case of the back side copy.

In order to synchronize with the original image, the transfer paper is
Transport at different timing depending on whether it is sent from the tray

If not, switch to the discharge side.

The discharge switching claw 122 is made of CNT. 7, the transfer paper is switched to be discharged to the main body tray or sent to the peripheral device. The sequence operation ends when the transfer paper is discharged.

Since the normal copying process is determined by the segment size and the size of the transfer paper used, the processing speed of the A4 size is the fastest, the B4 size is the next, and it is 4/5 of the A4 size. It becomes three-fifths in A3 size.

The change of the processing speed is realized by changing the correspondence between the segment size and the transfer paper size. That is,
Even if the transfer paper size is A4, it is possible to reduce the size to four fifths by using the B4 segment and to three fifths by using the A3 segment. When the transfer paper size is B4, by using A4 segment,
It can be three quarters.

Next, a specific operation corresponding to the invention described in the claims will be described. Here, the following symbols are used. m: index for program number array n: index for program number Nmax: maximum number of programs (constant) Mmax: maximum number of program arrays (constant) X [n]: program number to be executed nth (1 to Nmax maximum) Y [m] [n]: m array of the above (1
No. up to Mmax No.)

The operation of the invention described in claim 1 is as shown in FIGS.
It is realized by the procedure shown in the flowchart of FIG.

First, FIG. 8 shows a procedure for programming in an arbitrary order. When this function is called, an index that is 0 is added (S1), and it is checked whether the maximum number of programs has been exceeded (S2). If it exceeds the limit, no further input is possible (S6), and the process ends. If it does not exceed, the program number to be executed is input (S3). The input number is stored in the array X [n] (S4). Then, there, it is selected whether to end or continue input (S5). If you choose to continue, repeat from S1 again.

Next, the procedure for executing this is shown in FIG.
The indexes that are 0 are added (S11), and the array X is called. If nothing is stored there (expressed as X [n] = 0 here, there is no program 0), or if it exceeds the maximum value, the process ends (S12). If stored, the program is called and executed (S13, S14). When the execution end (S15) is confirmed, the index addition is repeated again.

The operation of the invention described in claim 2 is realized by the procedure shown in the flow charts of FIGS.

First, the procedure for registering numbers will be described with reference to FIG. The number m is selected by the selection means provided (S21). If m exceeds the maximum value allowed, it is considered as an input error (S22), and if it is within the range, it is checked whether there is a program array already registered in mth (S2).
3). If there is a sequence already registered, overwrite confirmation is performed (S24), and if confirmed, the program sequence is copied and saved (S25).

Next, FIG. 11 shows a procedure for calling and using the registered program array. First, the number m is selected by the selection means provided (S31). The index is added (S32), and if the program is registered in Y [m] [n] (S33), it is called (S3).
4) is executed. If there is no registration, the process ends. When the execution end (S36) is confirmed, the index is added again (S32), and the same is repeated thereafter.

The operation of the invention described in claim 3 can be explained in the same manner as the operation of the invention described in claim 1. For example, an example in which a plurality of programs in FIG. 12 are registered will be described. Since the programmed numbers are ignored and all the numbers are executed as 1, when executing numbers 1, 2, 3, 4, 5 in numerical order,
When the number is 2, 4, or 5, the number is plural, but these are all executed as 1.

Next, the operation and processing for setting the originals on the RDH 2 and the DF 3 and designating the programs for each will be described.

By setting the originals in the RDH 2 and the DF 3, respectively, it is possible to repeatedly make copies on the same original bundle under different conditions, and during the copying with another original bundle. Further, it is also possible to eject the copy placed on the RDH2 and instead introduce the document of the DF3 into the RDH2 to continue copying.

FIG. 12 shows the items stored in the basic program function, but the item of the original feed source may be added to this item. The sheet is fed from the paper source indicated in that item to the contact glass 101, and copying is performed. The paper source not specified is stopped. In this case, RDH2 can be specified as the paper feed source many times, but DF3 can be specified only once. However, when a plurality of DF3s are permitted, the document set can be confirmed by temporarily stopping.

Next, the operation and processing for repeatedly copying the original set on the RDH 2 while changing the program will be described. As mentioned above, RDH
Consider the case of repeating the document set in 2 and shifting from program number 1 to program number 2 in FIG. In number one,
Since the number of copies is 1, the document bundle set on the RDH 2 makes only one round. After copying for the specified number of copies,
Upon detecting this, the program is changed and the setting of No. 2 is made.

Here, since the magnification is changed and the transfer paper size is also changed, the transfer paper supply source is also changed. It is specified to sort further (if these cannot be set, an error will occur, and the operator will be informed of this: depending on each program function). In number 2, the number is 2
Since the number is 0, the bundle of originals in the RDH 2 (same original bundle) has 20 rounds because the finisher 4 is attached (one cycle is required for a sorter). The finisher 4
It is possible to create more than 20 copies, but this is not possible with a normal sorter. The finisher 4 and the RDH 2 are often used in combination.

[0059]

According to the invention described in claim 1, since a plurality of programs can be continuously executed in an arbitrary order, batch processing is possible and an image forming apparatus having a high operating rate can be provided.

According to the second aspect of the present invention, an arbitrary memory can be selected from among a plurality of programs stored in an arbitrary order, so that the range of selection of batch processing can be widened and an image for efficiently performing routine work can be selected. A forming device can be provided.

According to the third aspect of the present invention, by making it possible to easily confirm the setting contents of a plurality of complicated program groups, it is possible to reduce erroneous work and provide an efficient image forming apparatus. . In other words, it is possible to provide a trial copy function of program contents.
