Description

Description: TECHNICAL FIELD The present invention relates to a display control method in a copying machine or the like.

(Prior Art) Conventionally, in a copying machine, there is a method in which the dot display of pictographs is controlled by a microcomputer, and a control program is developed using only one-dimensional absolute address position information.

However, in this method, since the control program is developed using only one-dimensional absolute address position information, one pictographic character is used.
Many manual calculations are required for the one-dimensional absolute address position information, and there are many input errors and calculation errors in the one-dimensional absolute address position information, and since the one-dimensional absolute address position cannot be grasped intuitively, it is necessary to find and correct the mistake. It took a lot of time and development efficiency was not good.

(Object) It is an object of the present invention to provide a display control method capable of improving development efficiency, improving processing speed, compressing data by a simple method, and eliminating constraints on display position and display color. I do.

(Constitution) The present invention has at least two display layers of red and green, and at least red, green, white and black are formed by a combination of these display layers.
An apparatus having two-dimensional dot display means capable of expressing colors is provided with storage means having a memory space corresponding to the screen of the dot display means and having addresses continuously assigned thereto, as shown in FIG. As described above, the display information of the one-dimensional absolute address position information is calculated by the calculating means from the display information in which the coordinate information is two-dimensional coordinate information, stored in the storage means, and the display information is given from the storage means to the display means. Is displayed.

The display information in which the coordinate information is two-dimensional coordinate information is a macro that fills an area with one of red, green, white, and black using the two two-dimensional coordinate information. The contents of the storage means corresponding to the information in the area having two two-dimensional coordinate information as a diagonal are rewritten to one color data of red, green, white and black, and the display means rewrites the data in the area. The information may be erased to display the one color.

The display information in which the coordinate information is two-dimensional coordinate information is a macro that displays data registered in advance in one two-dimensional coordinate information in any two colors of red, green, white, and black. The data may be edited using the two-dimensional coordinate information as a starting point by a macro and then stored in the storage means and displayed on the display means.

Further, the display information in which the coordinate information is set as the two-dimensional coordinate information displays data registered in advance by one two-dimensional coordinate information in any three colors or all four colors of red, green, white, and black. The data may be stored in the storage means and displayed on the display means using the two-dimensional coordinate information as a starting point by the computing means.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.

 FIG. 2 shows an example of a copying machine to which the present invention is applied.

The copying machine includes a main body 100, a recycle-type automatic document feeder (RDF) 200, and a finisher (device for performing spelling for each part) 300.

In the main body 100, a flash exposure lamp and a power supply 101
Is provided, and the original on the original platen 102 made of contact glass is certified by the flash exposure lamp,
The reflected light is transmitted to the first mirror 103, the through lens 104, and the second
The photosensitive member 107 is exposed through the mirror 105. In this case, the regulating member 106 regulates the light from the second mirror 105 to the photosensitive member 107 so as not to expose an extra portion on the photosensitive member 107. Photoconductor
107 is rotationally driven by a motor, and is a corona discharger for charging 1
After being uniformly charged by 08, an electrostatic latent image is formed by the above exposure. In the photoreceptor 107, the area where the electrostatic latent image is not formed is discharged by the eraser 109, and the electrostatic latent image is developed by the developing unit 110.
And transferred to the transfer paper by the transfer corona discharger 111. This transfer paper is separated from the photoreceptor 107 by a separating corona discharger 112.

The transfer paper is stored in the first paper feed tray 113, the second paper feed tray 114,
Paper is fed from one of the paper feed trays 115 and is synchronized with the image on the
It is sent between 7 and the corona discharger 111 for transfer. Photoconductor 10
The transfer paper separated from 7 is transported by the transport tank 117, and the image is fixed by the fixing device 118. The fixing device 118 is configured using a fixing roller, and the separation claw 119 prevents the transfer paper from being wound around the fixing roller.

The behavior of the transfer paper after the fixing device 118 differs depending on the copy mode.

In the mode in which the transfer paper is discharged to the main body tray 123, the traveling direction of the transfer paper is determined so that the double-side switching claw 120 is at a position different from the illustrated position and the transfer paper does not advance to the double-sided tray. Further, the paper ejection nails 121 transfer the transfer paper to the main body tray 1.
It is switched to the position where it advances to 23, and the transfer paper is
It is discharged from 118 through the turn section 122 to the main body tray 123. At this time, the transfer sheet is turned on the image side by the turn section 122 and is provided on the main body tray 123 in page order from below.

Further, in the mode of discharging the transfer paper to the finisher 300, the discharge pawl 121 is switched to a position where the transfer paper is not advanced to the turn section 122, and the transfer paper is transferred from the fixing device 118 to the insertion opening 301 of the finisher 300. Is discharged.

In the above case, the transfer paper is discharged in the mode in which the transfer paper is discharged from the main body 100. However, in the mode in which double-sided copying is performed, the discharge of the transfer paper is different from the above-described case. The transfer paper on which the image is copied on the front surface exits from the fixing device 118, and the traveling direction is switched to the double-sided tray 124 by the double-sided switching claw 120, and is stored in the double-sided tray 124. Accordingly, the transfer sheets are arranged in page order on the double-sided tray 124 with the front side of the image copy surface facing upward. The transfer paper stored in the double-sided tray 124 is sequentially fed from a lower side by a double-sided paper feeding belt 125, conveyed in the same manner as the transfer paper fed from the paper feed trays 113 to 115, and is transferred by the registration rollers 116. Photoconductor 1
It is sent between the photoconductor 107 and the transfer corona discharger 111 in synchronization with the image on 07. The image on the photoconductor 107 is transferred to the back surface of the transfer paper by a corona discharger 111 for transfer, and is separated from the photoconductor 107 by a corona discharger 112 for separation.
The sheet is discharged to the main body tray 123 or the finisher 300 via the transport tank 117 and the fixing device 118.

The recycle type automatic document feeder 200 is the first document tray 2
01, second document tray 202, document reversing unit 225, continuous paper transport unit 2
24, and a document discharge tray 211, and has an ADF mode, an RDF mode, and a continuous paper feed mode.

In the ADF mode, the document set on the first document tray 201 is first fed from below by the feed belt 204,
The guide pawl 214 is pushed up through 05, passes through the conveyance paths 225 and 208, and is stacked on the second document tray 202 from the paper discharge port 223.
The documents stacked on the second document tray 202 are fed from below by a feed belt 209, sent to a predetermined position on the document 102 via an intermediate conveyance path 210, and copied by the main body 100 to a predetermined number of copies ( Exposure). The document on the document table 102 is conveyed leftward by the belt-shaped conveyance body 229 after copying, passes under the branching pawl 207, passes through the conveyance path 221 and exits from the paper discharge port.
The paper is discharged onto the paper discharge tray 211 from the 217. At this time, the branch claw 20
7, 222 are switched so that the document is discharged from the paper discharge port 217.

The RDF mode is a mode in which a predetermined number of copies are created by repeatedly exposing one copy of a document and repeating the above process to take one copy at a time. In the RDF mode, the movement until the first copy (exposure) of the document set on the first document tray 201 is completed is performed in the same manner as in the ADF mode described above in the same manner. The document on which the first copy (exposure) has been completed is picked up from the document table 102 by the branching pawl 207, sent through the transport path 225, and sent into the guide space 216 by the branching pawl 215. The rear end of this document is the guide pawl 206
, The transport drive source rotates in the reverse direction, and the original is fed into the transport path 208 with the previous rear end as the leading end, and the paper exit 2
From 23, the document is stacked on the second document tray 202 again. As a result, the exposed document is reset on the second document tray 202 in the same direction as before the exposure. At this time, the original document before exposure and the original document after exposure are selectively separated
Since it is clearly separated by 230, it is possible to know that one exposure is completed. By repeating this operation a predetermined number of times, it is possible to create a predetermined number of copies for each copy.

The basic operations of the ADF mode and the RDF mode are as described above. However, a so-called screen document in which information is present on the front and back of a document operates as follows.

When a two-sided document is processed in the ADF mode, the document set on the second document tray 202 is re-stacked on the second document tray 202 by idle feeding. This is the second document tray 202
Is discharged from the transport port 223 through the intermediate transport path 210 and the document table 102 through the transport paths 225 and 203, and is re-stacked on the second document tray 202. Thereafter, the document is sent to the exposure position through the same path as the above-described conveyance path during the idle feeding, and is sent into the guide space 216 via the conveyance path 225 when a predetermined number of exposures are completed. When the trailing edge of the document passes through the guide pawl 206, the transport drive source thus far reverses, and the document is fed backward with the trailing edge first.
This document advances along the intermediate conveyance path 210 by the action of the branching claws 212, is sent again to the document table 102, and the back surface is exposed a predetermined number of times. When the exposure is completed, the document is discharged onto a discharge tray 211. By performing such an operation on all originals, copying of a two-sided original is completed.

Next, when the double-sided document is processed in the RDF mode, the document set on the second document tray 202 is sent to the document table 102 via the conveyance path 210, and after being exposed once, the conveyance paths 225, 203
Is restacked on the second document tray 202 from the paper discharge port 223. At this time, the originals are stacked on the second original tray 202 in a state where the front and back sides are reversed from those before the exposure. Next, this document is conveyed to the exposure position along the same path as described above, and is discharged onto the second document tray 202 along the same path as described above after the back surface is exposed once. One copy of the copy copied on both sides by the above movement is completed, that is, one copy of the double-sided copy is completed by circulating the document twice. The document that has been circulated twice and re-stacked on the second document tray 202 is set in the same orientation as that initially set on the second document tray 202. By repeating these two cycles a predetermined number of times, a predetermined number of double-sided copies can be created from a double-sided original.

The ADF mode in which multiple copies are simultaneously made from one document by the above operation, and the RDF that creates multiple copies in page order by repeatedly setting the original while creating one copy from one document Mode is achieved. The former ADF mode is suitable for a system in which a sorter is connected to the main body 100 as a copy post-processing device, and the latter RDF mode is suitable for a system in which a finisher is connected to the main body 100 as a copy post-processing device. In this example, the finisher 300 is connected to the main body 100.

Next, the multi-job mode during document processing will be described.

This mode allows multiple sets of originals for the next job to be set in advance on other paper feed trays even when various copy processes are being executed, and when one job is completed, the next job is sequentially executed. This is a mode in which a predetermined copy operation is performed while changing the contents, and its main purpose is to eliminate a waiting time during copy execution.

In this mode, when one set of originals is set on the first original tray 201, data for inputting copy conditions in the direction in which paper is fed first (in this example, lower paper feed and the lowest). Load paper 234. When a plurality of sets of originals are set on the first original tray 201, the originals are set by inserting data sheets at the bottom of each set of originals in the manner described above. Feeding of this document is started by a feed start signal. First, data sheets are fed, and the copy conditions are read from the data sheets by the sensor group 226, and the copy condition is determined by the copy conditions. At the same time, the space of the second document tray 202 is set to the size of the document. After that, the data sheet 234 is transferred to the transport path 225, 210
Then, the document passes through the document table 102 and passes through the conveyance path 221 and is discharged onto the discharge tray 211 from the discharge ports 217 and 218. The original following the data sheet passes through the transport paths 225 and 208, and exits 223.
The document is discharged onto the second document tray 202 and stacked, and the ADF
Preparations are made for copying in RDF mode or RDF mode. Thereafter, the original on the second original tray 202 is copied as described above, and after the copy is completed, all of the originals are discharged to the paper discharge tray 211 to prepare for the next job. In this case, the first document tray
The end of each set of originals fed from 201 is determined when the next data sheet is sent out and detected by the sensor, and the next data sheet is stored in the first original apparatus until the next job is prepared. It is set to stay within 233.

Next, a copy mode for continuous paper (such as computer output paper) will be described.

Continuously folded paper is stored in the second document tray 202
And positioning is performed by the end plate and the side plate. Thus, the length of one fold of the sheet is read, and the number of feed perforations is determined.
The number of perforations determined here becomes a reference for feeding one page of the subsequent paper. The upper end of the sheet is set on a sprocket 219, and the sheet is fed onto the document table 102 through the conveyance path 220 by input of a feed signal. At this time, the leading edge of the sheet is determined by the sensor 228, and the sheet is fed a predetermined distance and stopped at a fixed position on the document table 102 based on the relationship between the position, the document setting reference, and the number of perforations, and is copied by the main body 100. . Thereafter, the sheet is fed one page at a time by the sprocket 219 and is sequentially copied. The copied paper is discharged from the paper discharge port 218 through the transport path 221 and is stacked on the paper discharge tray 211A while being folded. As a paper feed mode, there is a selection button for performing idle feed, continuous feed, and the like for each page.

In the finisher 300, the transfer paper discharged from the main body 100 passes through the insertion port 301, and is punched by the B4 punching roller 302, the A4 punching roller 303, and the A3 punching roller 304. This perforation is performed while the B4 perforating roller 302, the A4 perforating roller 303, and the A3 perforating roller 304 rotate as the transfer paper passes, and the perforation position differs depending on the size of the transfer paper. When the transfer sheet is B4, the transfer sheet is punched twice by the B4 punching roller 302, and when the transfer sheets are A4 and B5, the transfer sheet is punched once by the A4 punching roller 303. If the transfer paper is A3, A3
The sheet is punched twice by the punching roller 304. The punched transfer paper is aligned on the stapling tray 306 from the bottom in the page order by the turn unit 305, and is bound by the stapler 309. The bound transfer paper is sent out of the machine by a claw 311 fixed to a belt 312, and is discharged onto a paper discharge tray 310 which is provided to be vertically movable. In the case where only the perforation is performed without binding the transfer paper, the transfer paper is discharged to the upper discharge tray 123A through the guide 122A by the nail 121A. Further, the punching device performs punching for each transfer sheet. However, if a method of punching simultaneously or after binding is adopted, the problem of hole misalignment after binding can be solved.

Next, data to be drawn by the dot display unit 451 will be described.

The operation of filling an area having two two-dimensional coordinates as a diagonal with one color in a portion of the copying machine to which the invention of claim 2 is applied can be described with reference to FIG. In other words, the x coordinate and y coordinate (xs, ys) of the start point are
, X and y widths xw and yw, and color information are required. This means that given the two-dimensional coordinate information (x ₁ , y ₁ ) and (x ₂ , y ₂ ) of the start point and end point of this work, xs = x ₁ ys = y ₁ xw = x ₂ −x ₁ +1 yw = Y ₂ = y ₁ +1. The starting point S of the area on the display controller memory 450 is obtained as S = 140 × (y ₁ -1) + (x ₁ -1).

FIG. 16 is a flowchart of a macro for painting an area in white based on the two pieces of two-dimensional coordinate information. The operation control microprocessor 443 executes this by a macro from the mode control microprocessor 422. First, in step (a), two-dimensional coordinate information (x ₁ , y ₁ ) of xw, yw, S as a start point and an end point, Let S be S 'after obtaining from (x ₂ , y ₂ ) by the above equation. Then start, end point _{(x 1, y 1),} (x 2, y 2)
Step (b) to make the area having a diagonal as white
Then, the red dot and the green dot are written on the display controller memory 450 as lighting data, and the width in the x-axis direction is managed in step (c). When this writing is completed for the first row, the process moves to the next row in step (d), and this is repeated, and the width in the y-axis direction is managed in step (e).

Based on the above two two-dimensional coordinate information, each macro that fills an area with a color other than white (black, red, green) is the macro of FIG. 16 in which the content of step (b) is as shown in Table 2 described above. It just changes. That is, the contents of step (b) are as follows. In the macro that fills the area with black, the red dot is turned off and the green dot is written in the display controller memory 450 as off data. In the macro that fills the area with red, the red dot is turned on. Then, the green dot is written on the display controller memory 450 as light-off data, and in the macro for filling the area with green, the red dot is written on the display controller memory 450 as the light-off data and the green dot is written as light-on data. The operation control microprocessor 443 executes these macros by receiving these macros from the mode control microprocessor 422.

In this copying machine, the operation related to the portion to which the invention of claim 3 is applied, that is, data registered in advance in the dot display means starting from one piece of two-dimensional coordinate information is replaced with any two of red, green, white and black. The operation of displaying by color can be described with reference to FIG. In this work, the x- and y-coordinates (xs, ys) of the starting point and the x-direction and y
Width xw, and yw, color combination information of a necessary starting point from (x _1, y ₁₎ is Rarere if xs = x ₁ ys = y ₁ given, the 1-dimensional display controller memory on 450 The starting point S is obtained as S = 140 × (y ₁ -1) + (x ₁ -1). Also, xw and yw can be known by storing them in the first two bytes of data registered in advance as shown in FIG. 17 (a). The memory address P at which data registered in advance is stored must be known.

FIG. 18 shows a micro flowchart for drawing data registered in advance in the dot display means in white on a black background, starting from one piece of two-dimensional coordinate information. Perform this operation control microprocessor 443 by the macro from the mode control microprocessor 422, first xw in step (a), yw, 2-dimensional coordinate information of the starting point S (x _1,
y ₁ ) and the address P are obtained as described above. Next, in order to draw white on a black background, the data transfer edited in step (b) is performed. The editing here means inverting the data registered in advance as described with reference to FIG. 10, and the data is stored in the display controller memory 450.
And the width in the x-axis direction is managed in step (c) in step (c). When this writing is completed for the first row, the process moves to the next row in step (d), and this is repeated, and the width in the y-axis direction is managed in step (e).

Each macro that draws data registered in advance with the one piece of two-dimensional coordinate information as a starting point in a different color from the above macro is shown in Table 3 in the case of the macro shown in FIG. It just changes to That is, in the editing in step (b), for example, in a macro that draws a black figure on a white background, as shown in FIG.
