〔Example〕

 The present invention will be described in detail below with reference to examples.

In this embodiment, a copying machine will be described as an example of a recording device, and a function corresponding to an additional device when a function selection switch of the copying machine is operated and a display for the selection will be described as an example. Prior to the description, a table of contents for the description of the present embodiment will be shown.

(1) System configuration of copying machine (2) Software configuration (2-1) Merit of software combination (2-2) Example of differentiation (3) Example of device configuration (4) Device circuit configuration (5) ) Specific circuit configuration of copying machine (5-1) Around photosensitive drum (5-2) Switching mechanism of developing device (5-3) Optical system (5-4) Fixing device (5-5) Console Control (5-6) Billing counter (5-7) Power supply (5-8) Transport system (5-9) DADF (5-10) Sorter (5-11) Intermediate tray (5-12) Editor pad (5- 13) Large capacity tray (6) Area protrusion processing system (main part of the present invention) (6-1) Configuration of area protrusion processing system (6-2) Area protrusion processing in message display CPU (6-3) Area protrusion processing Message display in (6-4) Area outside Processing operation (6-5) Relationship between paper type and graphic memory area (6-6) Overhang processing in continuous shooting color composition (6-7) Display example in area overhang processing for various functions (1) System configuration of copier FIG. 2 shows a system configuration of a copying machine according to an embodiment of the present invention.

As shown in this figure, a copying machine which can use an IC card in the present embodiment can improve its function by attaching a desired additional device to a base machine 21 as the most basic configuration. Has become. Here, the base machine is a device that includes a single-stage supply tray and a manual feed tray, and is capable of manually setting a document on a platen glass and making a copy. The following additional devices can be attached to this base machine.

(1) IC card device 22; The IC card device 22 supplies necessary data to the base machine 21 using an IC card, and conversely, from the base machine 21.
This device is used when writing data to an IC card. When data (coordinate data) is input using an editor pad described later, the editor pad is connected to the IC card device 22 to perform input work. It should be noted that the IC card device 22 of the present embodiment selectively controls the IC card and the editor pad, and cannot input data by using both at the same time.

The IC card used for the IC card device 22 of the present embodiment has an ISO type interface and has a memory capacity of 2 kilobytes. By using an IC card,
Complex data can be stored in the card, and it is possible to sufficiently cope with automation and multifunction of the copying machine. For example, by preparing IC cards for each type of business or customer, even a copier with complicated functions can realize an operation method suitable for those owners, and anyone can easily and definitely The copier can be operated.

(2) ADF23 and DADF24; The ADF23 is generally called an automatic document feeder, which feeds documents one by one onto the platen glass of the base machine 21 and discharges them after the exposure.
The exposure of the document is performed only on one of the determined surfaces. On the other hand, the DADF 24 is an automatic document feeder for duplex, that is, double-sided copy. In the DADF 24, the original is conveyed in a state where one side of the original faces the platen glass, and the first exposure is performed. Then, when returning the original after the exposure to the tray of the DADF 24, the front and back are reversed. As a result, when the original is sent out again, the surface opposite to the previous exposure surface is exposed. The base machine 21 can copy the front and back sides of copy paper separately while using an additional device described later.

By using the ADF23 and the DADF24 in the copying machine of the present embodiment, it is possible to automatically perform a copying operation using various combinations such as a double-sided original and a double-sided copy.

Note that the ADF 23 has basically the same structure as an automatic document feeder conventionally used in a copying machine, but in the case of the apparatus of the present embodiment, the insertion direction of the original is from the left when viewed from the left, and the base machine 21 It has a shape that does not protrude.

(3) Normal platen 25 and platen 26 with editor pad; The platen 26 with editor pad has a structure in which a coordinate input device called an editor pad for editing an original is arranged on the platen. The ordinary platen 25 does not have such a mechanism.

(4) Console panel: There are two types of console panels: a backlit type 27 and a type 28 with a message display. Here, the back-lit type console panel 27 is configured such that a display plate on which a message fixed in advance at a predetermined position is selectively illuminated from behind by a lamp or the like so that the portion can be read.

The console panel 28 with a message display employed in the copying machine of the present embodiment is composed of a liquid crystal display element, and has an advantage that various messages can be displayed at any time without increasing the display area. . Which console panel is adopted is determined for each copier in consideration of the complexity of the system configuration of the copier, operability, and the like.

(5) Addition of supply tray; This has the following typical ecology. That is, in this embodiment, not only the addition of a large-capacity tray as proposed in Japanese Patent Application Laid-Open No. 57-77140 is realized, but also a combination of supply trays more suited to customer needs. Such a combination of supply trays is also disclosed in detail, for example, in "Multistage Paper Feed Copier" of Japanese Patent Application No. 61-081016 filed by the present applicant.

(A) Second and third supply trays 31-2 and 31-3; By adding these two supply trays, copy sheets of up to three types of sizes can be sent to the base machine 21.

(B) Second and third supply trays 31-2 and 31-3 and intermediate tray 33. Here, the intermediate tray 33 is a tray that temporarily stores the copied paper when performing copying a plurality of times on one surface of the paper or alternately performing copying on two surfaces.

(C) The second and third supply trays 31-2 and 31-3, the intermediate tray 33, and the fourth and fifth supply trays 31-4 and 31-5.

(D) Second and third supply trays 31-2 and 31-3, intermediate tray 33, and large capacity tray.

Here, the large capacity tray is a supply tray capable of storing thousands of copy sheets.

(5) A storage device for ejected copy sheets.

Copy paper is normally stored in the output tray 37, but this system provides a 10-bin sorter 38 and a 20-bin sorter 39. Therefore, by setting one of these sorters, copies can be sorted for up to 10 or 20 distribution destinations.

As described above, in this copier system, the base machine 21
Since various additional devices can be selectively attached to the printer, a copying machine most suitable for the user can be provided. In addition, the function of the copying machine can be improved in accordance with the change in the business form of the customer.

For example, customers who do not need to make copies by enlarging or reducing originals or customers who have a small copy
Often it is appropriate to purchase a single unit. On the other hand, the intermediate tray 33 and the large-capacity tray are often required for a customer who makes a large number of copies or a customer who requires a complicated copying operation. As means for fulfilling such various requirements, this copying machine system has a structure in which each additional device can be easily attached and detached,
In addition, for some of the additional devices, an independent CPU (central processing unit) is prepared to perform distributed control by a plurality of CPUs. This not only has the advantage that the customer's desired product can be easily obtained, but the possibility of installing a new additional device teaches the customer the possibility of a new copying operation. In terms of promoting the evolution of office paper processing, the purchase of this copier system will be very attractive.

(2) Software Configuration (2-1) Advantages of Software Combination By the way, the system configuration of the copying machine described above can also be described as a combination of software of the copying machine of this embodiment. That is, this copying machine can be equipped with various kinds of additional devices, and the software can have a system configuration corresponding to each of these additional devices.

One of the reasons for adopting such a configuration is that (i) if the operation control programs for all these additional devices are prepared in the base machine 21, the memory capacity required for this is enormous. It depends. Also,
(Ii) If a new additional device is developed in the future or the current additional device is improved, the ROM (read only memory) in the base machine 21 must not be replaced or expanded.
This is so that these additional devices can be utilized.

For this reason, the base machine 21 has a basic storage area for controlling the basic part of the copying machine and an additional storage area for storing a program taken together with the function information of the present invention from an IC card. Various programs such as a control program for the ADF 23, a control program for the DADF 24, and a control program for the console panel 28 are stored in the additional storage area. When an IC card is set in the IC card device 22 with a predetermined additional device attached to the base machine 21, a program required for a copying operation is read and loaded into the additional storage device.
The loaded program controls the copy operation in cooperation with the program written in the basic storage area or with a priority over the program.

(2-2) Example of differentiation As described above, in the copying machine of this embodiment, the program stored in the IC card can control the function of the copying machine.
Therefore, by changing the program stored in the IC card for each card, it becomes possible to differentiate the use of the copying machine. This will be described with some easy-to-understand examples.

As a first example, a multi-tenant building is equipped with a copier that is shared by a plurality of companies, or a copier that is shared by different departments within a single company or factory. The case will be described. The latter joint use is necessary for budget control, and in the past, use control of each department was performed using a device such as a copy riser.

This copier includes an IC card device 22, a DADF 24, a sorter 38, a console panel 28, and a base machine 21 shown in FIG.
It is assumed that the copying machine has a relatively high system configuration including the second to fifth supply trays 31-2 to 31-5 and the intermediate tray 33. Some co-users require the DADF 24 and / or sorter 38, while others do not require any additional equipment.

If a plurality of persons or departments having different usage modes try to determine the cost burden of the copying machine solely from their own copy volumes, those who only make low-volume copies will be required to make copies with various additional devices. This would oppose the introduction of the copier, making it difficult to coordinate with people or departments that want to use the copier to a high degree.

In such a case, prepare an IC card according to the usage pattern of each person or department so that the person or department that desires advanced functions will bear the basic cost and utilize many functions. You just need to be able to do it. For example, the owner of the most advanced IC card operates the copying machine with the IC card set in the IC card device 22 to cause the DADF 24, the sorter 38, the second to fifth supply trays 31-2 to 31 to operate. -5 and the intermediate tray 33 can be used freely, and office efficiency can be improved. On the other hand, those who don't need to sort copy papers have an IC that lacks a program for sorting.
The cost can be reduced by setting a card and using the uppermost bin of the sorter 38 as a discharge tray.

As a second example, a case where a photocopying company runs a self-copying service store with an IC card will be described.

In the store, a plurality of copiers are arranged, each of which is equipped with an IC card device. The customer requests an IC card according to the service type, sets it in the copier of his choice, and makes a self-service copy.
Customers who are unfamiliar with the copier request an IC card equipped with a program for displaying operation explanations as a program, and by setting this, it is possible to display various types of operation information on the console panel 28, so that copying work can be performed without fail. be able to. DA
Whether the DF24 can be used, whether multi-color printing can be performed, and the like can be determined by the IC card to be lent, and the type of use can be limited, so that customers who are charged can be managed. In addition, since the actual copy work such as the number of copies and the size of copy paper used can be written in the IC card, billing becomes easier, and detailed services such as discounts on copy fees for regular customers are also possible. .

As a third example, a service using an IC card that stores a program for a specific user will be described. For example, a patent office needs to make a copy of the original size when examining patent publications reduced by photoengraving.
I have a job to make a copy with a relatively large enlargement ratio of 0%. In addition, when a drawing to be submitted to the government office is created, the original drawing is shrunk or enlarged in order to meet the request. In addition, in departments that copy resident's cards such as city halls or ward offices, copies of the information about people who are not covered by the claim and places that should be kept secret in order to protect personal privacy are copied. And make an abstract.

As described above, depending on the user (user), there is a request to use the copying machine in a special usage mode. If the functions of the copying machine are set so as to satisfy all such requirements, the console panel becomes complicated and the ROM inside the copying machine becomes large. Therefore, by preparing an IC card for each specific user and setting it, it is possible to realize a copier having the most suitable function for that user.

For example, in the case of a patent office, by purchasing a dedicated IC card, in addition to several normal reduction ratios as a fixed ratio,
You can easily select a reduction ratio of 200%. Further, it becomes possible to set the reduction ratio in steps of 1%, for example, within a range that requires fine adjustment. Furthermore, in the resident card issuing department, it becomes possible to instruct the type of resident card and the fields and items to be deleted on the display such as the liquid crystal display by operating keys such as the numeric keypad, and then click the start button. By pressing, only the desired area of the original is copied, or only the necessary portion is edited and recorded.

(3) Example of Apparatus Configuration FIG. 3 is an external view showing an example of the system configuration of the copying machine of the above-described embodiment.

In the copying machine of this embodiment, the DADF is placed on the base machine 21.
The IC card device 22 is disposed behind the upper surface of the IC card device 24. A console panel 28 with a message display is arranged in front of the upper surface of the base machine 21. Although not shown in the figure, a manual feed tray 41 is attached to the right side of the apparatus, and a 10-bin sorter 38 is attached to the left side. Although the manual feed tray 41 is for manual feeding, a plurality of sheets can be set at the same time and sequentially fed.

As described above, the first supply tray 31-1 is attached to the base machine 21 as its basic configuration. In the copying machine of this embodiment, the second and third parts are provided therebelow.
Supply trays 31-2 and 31-3 are arranged, and the fourth and fifth supply trays 31-4 and 31 are provided with the intermediate tray 33 interposed therebetween.
-5 is placed. These supply trays 31-1 to 31-
The fourth and intermediate trays 33 can both be pulled out to the front, so that operability is improved and the space required for the copier is saved. The ADF (Automatic Document Feeder) and a copier with a clean design that does not protrude the paper feed tray have been realized.

FIG. 4 shows an outline of this copying machine. In the base machine 21, a photosensitive drum 51 is arranged.
The photosensitive drum 51 is uniformly charged by a charge corotron (charger) 52. Photoconductor drum
In the drawing, 51 rotates at a constant speed in the direction of an arrow 53, and the charged drum surface is exposed at an exposure location 54. Here, an optical image of an original document (not shown) placed on the platen glass 55 arranged on the upper surface of the base machine 21 is made incident on the exposed portion 54. For this purpose, an exposure lamp 56, a plurality of mirrors 57 and an optical lens 58 for transmitting reflected light of the document surface illuminated by the exposure lamp 56 are arranged, and a predetermined one of them is scanned for reading the document. It is supposed to be.

Now, an electrostatic latent image corresponding to the document is formed on the photosensitive drum 51 by the image information exposed in a slit shape at the exposure portion 54. This electrostatic latent image is developed by the developing device 59 to form a toner image. Toner image is a photoconductor drum
It moves with the rotation of 51 and passes near the transfer corotron (transfer device) 50.

On the other hand, copy paper 60 accommodated in the first supply tray 31-1 arranged in the base machine 21 or copy paper 60 manually fed along the manual feed tray 41.
Is sent by the feed roll 61-1 or 63,
It is guided by the transport roll 69 and passes between the photosensitive drum 51 and the transfer corotron 50. At this time, the toner image is transferred onto the copy sheet 58. The copy paper 60 after transfer is a heat roll 66 and a pressure roll 67.
It is passed through the space and is heat-fixed. Then, the transport roll 68,
The paper passes through 68 and is discharged onto a discharge tray (not shown).

In the copying machine of this embodiment, the base machine 21 has a DADF
I have attached 24. Accordingly, both sides of the document can be sequentially placed on the platen glass 55. In this case, one side of the document stacked in the document storage portion of the DADF 24 is first set on the upper surface of the platen glass 55. Then, when the copying is completed, the original is set upside down in the original accommodation portion, and thereafter, it is fed again onto the platen glass 55.

Further, in the copying machine of this embodiment, the five trays 31-2 to 31-5 and 33 are mounted under the base machine 21, but instead of this, a cabinet may be simply arranged to store consumables. . Further, it is also possible to mount this copier as a desktop copier on a desk with the configuration of the base machine 21 as it is. Of course, the first supply tray 31
It is also possible to mount only the second supply tray 31-2 under -1, and to similarly mount the copying machine having this configuration on a desk.

FIG. 5 shows an example of a console panel of the copying machine. The details of the display control technology described below by the present applicant are disclosed in detail in, for example, a "display device" of Japanese Utility Model Application No. 61-130320 and a "character display device" of Japanese Utility Model Application No. 61-066170. . For example, Japanese Utility Model Application No. 61-130320 discloses that a copying machine is provided with a graphic display area using a dot pattern, and it is suggested that various displays can be performed using the graphic display area. For example, in a copier capable of partially copying a document or moving / deleting an image, an image of a target area is read by an image sensor with the document placed on a platen, and its outline is displayed in a graphic display area. It is suggested that an error in area setting and an operation error can be prevented.

Although the console panel can take a plurality of forms, as described above, the copying machine of the present embodiment uses the console panel 28 with a message display.

Now, on the console panel 28, the menu display board 71 is arranged on the upper part thereof, and the respective panel parts 74 to 79 are arranged.
The content of is displayed in characters. Among them, one switch 81 and two display lamps 82 are arranged on the sorter panel 74 so that a sorting mode when a sorter is connected can be selected. Sorting modes include a stack mode for sequentially stacking copy sheets and a collating mode for sorting copy sheets into each bin of the sorter.

The next function selection panel 75 has (i) a switch 83 for editing, correcting, and confirming an image, (ii) a switch 84 for storing the image in the job memory, and (iii) other various copying modes. Switch for 85 and (iv)
A switch 86 for making double-sided copying and a display lamp 82 for displaying the presence or absence of selection of these switches are arranged. Here, (i) editing is a function for inputting data for editing using an editor or the like, and correction / confirmation is a function for displaying input data on a liquid crystal display unit to be described later, for confirming, Function to replace (Ii) The memory used here is a non-volatile memory composed of a random access memory backed up by a battery. Of course, other storage media such as IC cards, magnetic cards and floppy disks can also be used as the non-volatile memory. In this copier, in order to reduce the burden on the operator of operating the console panel 28, setting of image density and magnification can be preset, and the preset values are stored in a non-volatile memory. It is supposed to.
(Iii) When the switch 85 is pressed, the console panel 28
The character information is displayed on the display panel 79, and a desired function can be selected from the "other" functions.

The “other” functions here include, for example, (a) a page continuous shooting function, (b) a frame erasing function, and (c) a binding margin function. Of these, the (a) page continuous shooting function is a function of sequentially dividing a document such as a bookbinding document that extends over two pages into two pages in a spread state and sequentially copies the pages. The (b) frame erase function is a function that does not copy the image information in the peripheral part of the original, but creates a "frame" around the image information.
It is a function to set as. (C) The binding function is a function for setting a "binding margin" at the right end or the left end of a copy. The binding margin can be set to the desired length, and its value can be entered from the numeric keypad 80 or displayed on the display panel.
You can select from the numbers displayed at this point on 79.

(Iv) Finally, double-sided copying is a function of making copies on both sides of copy paper. In the case of making a double-sided copy, the copy paper 60 on which the copy has been made on the first side is first stored in the intermediate tray 33 shown in FIG. Next, the copy sheet 60 is sent out again from the intermediate tray 33, and the copy is performed on the surface on which the copy has not been performed. In this copying machine, copying is performed twice on one side in the case of monochromatic color copying described below. In this case, a contrivance has been made so that the front and back sides of the copy sheets stored in the intermediate tray 33 are opposite to those in the case of double-sided copy.

A display lamp indicating the type (color) of the color developer is provided at the top of a monochromatic color emphasis panel 76 provided below a portion where "monochrome color emphasis" is displayed on the menu display plate 71 in FIG. There are four 87s. In this copying machine, the color developer can be set in one color or a plurality of colors out of four colors such as red and blue, so that the lamp corresponding to the currently set color is turned on.

On the remaining portion of the single-color highlighting panel 76, four switches 88 to 91 and a display lamp 82 for displaying which of the switches 88 to 91 are set are arranged. Of these, (i) marking color switch 88
Is a switch used for performing a marking color. When the area to be marked is designated by pressing the switch 88, for example, a light color is superimposed on the area and recording is performed, and an effect as if the marking was performed can be obtained.

(Ii) The continuous shooting color synthesizing switch 90 is used for recording one color in a predetermined area of a copy. For example, if a figure to be expressed in color is placed on the right side of the platen glass 55 (see FIG. 4) and a document is placed on the left side and a copy is taken,
The image information of the original is copied in black, and the graphic is drawn thereon in one color. At this time, if the designated graphic is formed by a halftone dot, a color graphic adjusted to a predetermined density by reproducing the halftone dot is recorded in a predetermined area of the copy sheet. In addition, there is also a method of arranging a product name or a pattern on one side of the platen glass 55, arranging a paper on which the sale price of the product is written on the other side, and simply displaying the price at that time.

(Iii) When the partial color conversion switch 89 is selected, only the designated area is copied in one color, and the remaining part is copied in black. On the other hand, (i
v) When the monochrome color switch 91 is selected, the original is copied in one color.

On the copy density panel 77 provided below the portion where "copy density" is displayed on the menu display plate 71, a display lamp 82 indicating which of the five copy density levels has been selected.
And shift keys 94 and 95 for selecting one of these copy densities. When the upper shift key 94 is pressed, the density setting is performed in a direction in which the copy density becomes lighter, and when the lower shift key 95 is pressed, the density setting is performed in a direction in which the copy density becomes darker. The copy density can be changed by changing the developing bias of the developing device 59 shown in FIG. 4, changing the amount of light of the exposure lamp 56 (FIG. 4), or applying a charge to the photosensitive drum 51 by the charge corotron 52. It can be adjusted by changing the amount.
In this embodiment, for example, the developing bias can be adjusted in 16 steps.

Below the copy density panel 77 is the automatic density adjustment switch 97
Is arranged. When the automatic density adjustment switch 97 is pressed, the automatic density display lamp 98 is turned on to enter the automatic density adjustment mode. In this automatic density adjustment mode, a part of the light that is reflected from the document and reaches the photoconductor drum 51 while the document is being scanned is extracted by a half mirror, etc. The potential of the developing electrode is set at.

A portion for setting and displaying a magnification is disposed on the left side of the magnification / paper selection panel 78 provided below the portion where “arbitrary magnification” or the like is displayed on the menu display plate 71, Is provided with a section for selecting a sheet.

Magnification display section 99 is used to set and display the magnification.
Is provided. This copier can set the magnification (linear magnification) from 50% to 200% in 1% increments.
The set magnification is displayed on the magnification display section 99. There are two types of magnification display, a method of setting an arbitrary magnification by operating the shift keys 101 and 102 and a method of selecting a predetermined fixed magnification.

To set an arbitrary magnification, shift keys 101, 102
Perform the above operations. When the upper shift key 101 is pressed, the magnification increases by 1%, and when the lower shift key 102 is pressed, the magnification decreases by 1%. When the shift keys 101 and 102 are kept pressed, the magnification changes continuously by 1% during that time.

Selection of a fixed magnification is performed by pressing a fixed magnification key 103. The fixed magnification is displayed on the magnification display plate 104,
In this example, they are 141.4%, 86.5%, 81.6% and 70.7%. In addition, 100% as the same magnification can be selected. Which magnification has been selected can be known from which of the display lamps 82 arranged on the left side thereof has been turned on.

Eight kinds of display plates 105 displaying the paper size or the kind of paper and shift keys 106 and 107 for selecting one of these are arranged in the portion for selecting the copy paper. On the left side of the eight types of display plates 105, a display lamp 82 indicating which paper size or paper is selected is arranged. In this embodiment, the display panel 10
At 5, the following display is made.

(B) Manual feed tray display: Select when using the manual feed tray 41 (Fig. 4).
Since the conventional manual feed tray of this kind is manually fed one by one, it is sufficient to preferentially send out copy sheets from the manual feed tray when the manual feed is performed, and the operator does not need to select the manual feed tray itself. On the other hand, the manual feed tray 41 of this embodiment can simultaneously set a plurality of copy sheets. Therefore, if the feeding from the manual feed tray 41 is performed by setting the copy sheets, the feed may be started when a plurality of copy sheets are set. In order to prevent such a situation,
The manual feed tray 41 is selected.

An automatic paper / magnification selection switch 109 is arranged below the magnification / paper selection panel 78. This switch 109
When is pressed, the automatic paper / magnification selection switch 109 is selected and a preset combination of magnification and paper size is selected. The operator can know whether or not a desired combination is selected from the lighting state of the display lamp 82 on the magnification / paper selection panel 78. If the combination is not the desired combination, the automatic paper / magnification selection switch 109 is further depressed to change the combination.

A display panel 79 is arranged on the right side of the magnification / paper selection panel 78. The display panel 79 shows the design of this copier.
111 and a liquid crystal display unit 112 are arranged. The symbol 111 displays the selection state of the supply tray, the location where a paper jam has occurred, and the like by lighting a lamp. The liquid crystal display unit 112 of this embodiment can display a sentence including Chinese characters. The example shown in FIG. 5 indicates that the copying operation can be started and that the set number of copies is one. Further, the liquid crystal display unit 112 of this embodiment uses liquid crystal for color display, and designated areas are displayed in designated colors.

Below the display panel 79, the following keys or buttons are arranged.

(A) All clear button 114; a button for returning the copying machine to the basic state, that is, the priority mode that is initially set such as selection of the copy paper 60.

(B) Numeric keypad 80: Used for setting the number of copies and for inputting numerical values for specifying the contents of diagnosis when performing diagnosis of the copying machine.

(C) Interrupt button 115; used when continuous copying is being performed and another emergency copy needs to be made. It is also used to release an interrupt for returning to the original copy operation when the interrupt processing is completed.

(D) Stop clear button 116; Acts as a clear button when the copying operation is stopped halfway, when the number of copies is set, and when the sorter bin is set.

(E) Start button 117; a key for starting a copying operation.

(F) Selection key 118; a key for moving a cursor to a displayed message, that is, a cursor key.

(G) Setting key 119: A key (return key) for setting at the location designated by the cursor.

As described above, the console panel according to the present embodiment has a layout in which an area for basic operations such as paper selection and copy density setting and an area for applied operations such as function selection and monochromatic color enhancement are completely separated. . In addition to this, by displaying a kanji / kana mixed sentence on the liquid crystal display unit 112 to assist the applied operation, the occurrence of errors in the panel operation is reduced as much as possible.

(4) Circuit Configuration of Apparatus FIG. 6 shows an outline of a circuit configuration of the copying machine (FIG. 2).

As shown in the figure, a distributed CPU architecture using serial communication centered on the main CPU 121 is adopted. This is to enable optimal placement of the controller and provide optimal cost performance. Further, from the viewpoint of product development of copying machines, it is expected that software development can be shortened and made more efficient by module design, wire harnesses and the like can be simplified, costs can be reduced, and trouble handling can be simplified.

In addition, since the processing efficiency is improved by decentralizing the processing by a plurality of CPUs, for example, a program that requires complicated and high-speed processing by using an inexpensive 8-bit CPU instead of using an expensive 16-bit CPU Can be performed.

Further, the decentralization of the processing facilitates the model development. That is, even when a new input / output device or the like is developed, it may not be necessary to modify the program on the main unit (main CPU side), and even when a change is necessary, the program can be minimized.

In addition, regarding the printed circuit board on the main body side, there is no need to store unnecessary I / O ports and programs by dispersing the CPU. Therefore, the cost of the printed circuit board can be reduced, and the degree of freedom of the arrangement space is improved.

This copying machine controls the base machine 21 by a main CPU (central processing unit) 121 and an inter-image lamp CPU 122 in the base machine 21. Here, the CPU 122 for the inter-image lamp is a CPU that specializes in controlling the inter-image lamp.

Inter image lamp is a photosensitive drum after exposure.
It is used for irradiating light to 51 to erase a part of the electrostatic latent image before development. Conventionally, for example, when copying an original of B5 size at the same size,
By irradiating light to an area other than the B5 size, a toner image was prevented from being formed wastefully outside the area. The copying machine of the present embodiment has a function of editing an image and the like as described later. Therefore, it may be necessary to limit the formation of the electrostatic latent image to, for example, a predetermined rectangular area or polygonal area, and it is necessary to partially delete the electrostatic latent image to perform such processing. I do. For this purpose, an inter-image lamp is used. As described above, in the copying machine according to the present embodiment, the inter-image lamp is used while being controlled at a higher level than in the related art. For this purpose, an independent CPU is used in addition to the main CPU 121.

One of the manufacturers that have introduced such a distributed processing system as a method of controlling a copying machine is Xerox Corporation.

CPU. This CPU is arranged on the rear side of the tray cabinet containing each tray, and performs these controls in accordance with the connected trays. Among these trays, the intermediate tray 33 has its own motor for transporting copy paper, and the copy paper stored in this tray requires complicated control such that the storage position varies depending on its size.

The control mode of each tray by the tray control CPU 128 is as follows.

(I) Control of both or one of the fourth and fifth supply trays 31-4 and 31-5 and the intermediate tray 33.

(Ii) Control of the large capacity tray and the intermediate tray 33.

(Iii) Single control of the intermediate tray 33.

(Iv) Control of only one or both of the fourth and fifth supply trays 31-4 and 31-5.

(V) Independent control of large capacity tray.

(E) Card CPU 129; When the IC card 131 storing the function information of the copier and the additional control information is used, the card CPU 129 reads the IC card 131 and uses the IC card 131 to specify the coordinates of the original. This is a part for performing reading and writing when used. Although the card CPU 129 is not used in the present embodiment, it can control the editor pad 132. The editor pad 132 is used for inputting coordinates, and will be described later in detail.

FIG. 7 more specifically shows a circuit configuration centered on a main CPU which plays a central role in the copying machine of this embodiment.

Controlling the copier with a control device such as a CPU or a so-called microcomputer is based on an IEEEE paper (A Programmable Digital Control System for Copy) by SIKANDAR SHEIKH of Xerox Corporation.
ing Machines ”IEEE Trans, Com, Vol IECI-21, No.1, Fe

According to the system configuration of the copying machine of this embodiment, copy paper 60 can be sent out from a maximum of five types of trays. Therefore, assuming that four sensors are arranged on one supply tray for detecting the paper size and digital data is used for this processing, it is necessary to send 4-bit digital data from one tray to the main CPU 121. Not only do you need up to 20 input ports in total, but you also have to increase the number of connectors and the number of cables that make up the harness. This is not preferable from the viewpoint of cost, reduction in size, and reliability.

Therefore, in the copying machine of this embodiment, four trays are provided for each tray.
A state specified by the states of the two sensors is transmitted as analog data. The main CPU 121 converts the sent analog data into digital data, and determines the size of the copy paper 60 stored in each tray up to 16 types.

(C) Further, the main CPU 121 is reset by the reset circuit 138 at the time of runaway or initialization, and the bus line 121A
It is connected to each of the following parts via.

(Iv) RAM 121E; a random access memory for storing data when having a capacity of 6 Kbytes. The above-mentioned nonvolatile memory (NVM) 121F is connected to the RAM 121E so that necessary data can be stored even when the power of the copying machine is turned off.

Here, the necessary data stored in the nonvolatile memory (NVM) 121F includes, for example, (a) a setup value for adjusting the registration of the copy sheet 60,
(B) the amount of extinction at the tip of the image by an inter-image lamp, which will be described in detail later; (c) fine adjustment values of the vertical and horizontal magnifications when the copy magnification is set to 1: 1;
(D) the adjustment value of each parameter performed on the production line of the copying machine, such as the amount of binding when a copy is performed with a blank for binding, and (e) the actual use of the feed counter of each supply tray 31 and the like. Examples of the data include data for grasping the use state of the copying machine such as a value. (F) Depending on the device, a conversion table of function information between copying machines may be written in a non-volatile memory. In this case, there is an advantage that the conversion table can be appropriately rewritten using external information such as an IC card.

(V) First I / O controller 121G; an input / output controller that inputs various data via a filter circuit 121H and drives various components via a driver circuit 121I.
Here, for example, various switches and sensors are connected to the filter circuit 121H. The driver circuit 121I includes a solenoid such as a debesolenoid described later and a supply tray.

According to the processing of the program, the setting of the development bias of the developing device 59 and the setting of the current value of the charge corotron 52 and the like described later. It is supposed to do.

(5) Specific Circuit Configuration of Copying Machine Next, the circuit configuration of the copying machine of this embodiment will be described more specifically with reference to FIGS.

(5-1) Periphery of Photoconductor Drum FIG. 8 shows the periphery of the photoconductor drum 51.

Around the photosensitive drum 51, the charge corotron 52,
Inter image lamp 141, 4 types of sub developing device 59S
1-59S4, Main developing unit 59M, Transfer corotron
50, Detac Corotron 147, Preclean Corotron 1
48, cleaning device 149 and erase lamp 1 for static elimination
55 are arranged in this order. Here, the first sub developing device 59S1 is a developing device that develops with red toner,
The second sub-developing device is a developing device for developing with blue. The third sub-developing device 59S3 is a developing device for developing with green toner, and the fourth sub-developing device 59S4 is a developing device for developing with brown toner.

The inter-image lamp 141 is composed of 128 light emitting diodes arranged in a line and one plastic lens arranged in front of these light emitting diodes in parallel with the light emitting diodes. The plastic lens (not shown) has an aspherical convex portion at a position corresponding to each light emitting diode, so that even when the adjacent portions of the light emitting diode emit light, the photoconductor drum 51 has The light is taken into consideration so that it does not have a uniform intensity in those boundary areas. Also,
The focus of the plastic lens is appropriately blurred on the photosensitive drum 51. For this reason, even when, for example, a graphic processing (extraction or deletion of a figure) of a triangular shape is performed by the inter-image lamp 141, a step generated for each light emitting diode in one unit at the boundary of the processing is considerably reduced. Will be done.

The inter-image lamp controller 157 controls ON / OFF of the light-emitting diodes divided into 128 segments of the inter-image lamp 141. The cleaning device 149 includes a doctor blade 150, and scrapes off the toner whose charge has been removed by the pre-clean corotron 148 from the photosensitive drum 51.

By the way, in the copying machine of this embodiment, the doctor blade 15
The drive of the main meter 164 is started when 0.2 seconds have passed after 0 touched the photosensitive drum 51. When the main motor 164 stops, the doctor blade 150
Does not separate from the photosensitive drum 51 but after 5 seconds. This is a device for preventing a situation in which the toner is scattered by the vacuum suction operation and contaminates the inside of the copying machine.

Each of the sub developing devices 59S1 to 59S4 includes the following components.

(A) Color sensor: a sensor for determining which color developing device is used for each of the sub developing devices 59S1 to 59S4. Even when the sub-developing device 59S is configured by a combination other than the above-described red, blue, green and brown, the sensor can detect the color type for each of the sub-developing devices 59S1 to 59S4. The detection output is input to the developer detection circuit 230 and transmitted to the main board 230.

(B) Toner sensor: A sensor for determining whether or not toner needs to be replenished.

(C) Dispense motor: A motor for stirring and replenishing the toner in the toner box.

The main developing device 59M is for performing development using black color, and includes a toner sensor and a dispense motor. The increase switch 159 is a switch that the operator pushes when he wants to increase the amount of toner. Sub developing device
When one of 59S1 to 59S4 is selected and the incremental switch 159 is pressed, the amount of toner is increased for the corresponding sub developing device. Main developing device
When 59M is pressed in the selected state, the amount of black toner is increased.

The development (developing device) selection / solenoid 161 is a solenoid for selectively switching a total of five developing devices of the main developing device 59M and the sub developing devices 59S1 to 59S4. This switching operation will be described again in the next section.

A high-voltage power supply (HVPS) 162 is used to create a parallel electric field inside the main and sub developing devices 59M and 59S1 to 59S4 to improve the reproducibility of the solid portion (solid black portion) of the original. . The full toner sensor 163 is a sensor that detects whether or not the toner has been sufficiently collected in the toner collecting container. The main motor 164 is used to drive the transport system from the time when the transport timing of the photosensitive drum 51, the heat roll 66, or the copy paper 60 is matched (registration) to the time of discharge.

(5-2) Switching Mechanism of Developing Device FIG. 9 is a waveform diagram showing switching timing of the main developing device and the sub developing device of the present embodiment. The figure shows 1
This shows an example in which red color development is performed in the first sub developing device 59S1 the second time, and monochrome development is performed in the main developing device for the second time. Copier start button 117
When (Figure 5) is pushed the copy operation is started, the main motor 164 from the time t ₁ as shown in figure a is driven. The main motor 164 is driven by two developing devices 59S.
Copy operation is performed continuously until the time t ₃ to end in both of 1,59M.

FIG. 6B shows the drive timing of the development selection / solenoid 161. The deve selection / solenoid 161 is excited until the copy operation of red color by the first sub developing device 59S1 is completed. In this device, the lever is brought into contact with the peripheral surface of a clutch (not shown) by the excitation of the development selection / solenoid 161. The clutch receives the transmission of the driving force from the main motor 164, and starts rotating five sets of cams (not shown) each having one protrusion with a shift of 72 degrees. When one of these protrusions is provided on the first sub developing device 59S1, the first sub developing device 59S1 is pressed in the direction of the photosensitive drum 51. At this time, the protrusions of the remaining cams are located farthest from the main developing device 59M and the other sub developing devices 59S2 to 59S4. In this state, the main developing device 59M and the other sub developing devices 59S2 to 59S
Reference numeral 4 is a position away from the photosensitive drum 51.

Protrusions are arranged at five places on the peripheral surface of the clutch, and when the lever hits the corresponding protrusion, the corresponding protruding portion of one cam is most strongly pressed against the first sub developing device 59S1. I do. Then, at this position, development is performed with the corresponding red color toner. However, in this apparatus, since the main developing device 59M is arranged close to the photosensitive drum 51 in the initial state, the development of colors such as red does not start immediately at time t ₁ , but The operation is waited for 1 second. At this time, the cam sets the first sub developing device 59S1 (or other sub developing devices 59S2 to 59S4) on the photosensitive drum 51 instead of the main developing device 59M.

When the copying work by the first sub-developing device 59S1 is completed, the above-mentioned five cams are moved for one _second from the time t2, and the protrusion of the monochrome cam is positioned by the lever. Are set on the photosensitive drum 51. Thereafter, monochrome development is performed.

Note that the above is the case where marking is performed with one color of red, but when marking is performed with a plurality of colors, the corresponding one of the sub-developing devices 59S1 to 59S4 is selected in order in a predetermined order. Then, after these are completed, monochrome development is performed.

FIG. 10 shows a case where development is performed first in monochrome and then development is performed in red color for reference. FIG. A shows the operation of the main motor 164,
FIG. 6B shows the operation of the development selection / solenoid 161. In the case of FIG. 10, the main developing device is first
Since development is performed at 59M, it is not necessary to wait for 1 second at this point. However, when the monochrome development is completed as the second development, it is necessary to set the main developing device 59M to the photosensitive drum 51 again after one second.

(5-3) Optical System Next, the relationship between the optical systems will be described with reference to FIG.

A carriage (not shown) on which a lens, a mirror, and the like are arranged is reciprocated by a carriage motor 171. The carriage motor 171 is constituted by a step motor. Position control when the carriage returns to the home position is performed by the registration sensor 172.

The registration sensor 172 is also used for timing the optical system and the conveyance of the copy paper 60. That is, an actuator for blocking transmission of light is arranged in the carriage, and when the carriage moves, the registration sensor 172 detects a temporary interruption of the light beam due to the light blocking by the actuator. Using this detection signal, the position or timing for performing registration is determined, and the position of the home position when the carriage returns is determined.

The density control sensor 173 is a sensor for controlling the copy density of the document. As described above, the copying machine of the present embodiment controls the copy density by simultaneously performing the three adjustments of the amount of charge applied to the photosensitive drum 51, the amount of image exposure, and the bias of the developing electrode. The lens / mirror sensor 174 is a sensor for controlling the movement of the optical lens 58 and the mirror 57 (FIG. 4), and is constituted by one detection element. The lens / mirror / motor 175 is also changed from a conventional copying machine in which the lens 64 and the mirror 57 are separately driven to a type which can be commonly driven. The exposure lamp 56 has been described above. The optical system fan 177 is a fan for removing heat of the platen glass 55 by air cooling the optical system. The document sensor 178 is a sensor provided to detect the size of the document.

Shown in Figure 12.

In the base machine 21 of this embodiment, two types of fuser lamps, a main fuser lamp 181 and a sub fuser lamp 182, are arranged in the heat roll 66. The sub-fuser lamp 182 is shorter than the main fuser lamp 181, and is arranged at a position slightly deviated from one end of the main fuser lamp 181. The copying machine of this embodiment employs a so-called corner registration (corner registration) method in which the copy paper 60 is positioned according to one side of the platen glass 55. Therefore, the required amount of heat energy in the axial direction of the heat roll 66 varies. In order to correct the deviation of the temperature distribution in the axial direction, the sub-fuser lamp 182 is controlled to be energized according to the size of the copy sheet 60. Subfuser lamp 18
By adopting 2, it becomes possible to sufficiently prevent temperature unevenness of the fixing device.

The fuser outlet sensor 184 and the S / T / S are provided in the fixing device.
(Soft touch sensor) 185 are both connected. Here, the fuser outlet sensor 184 is the heat roll 66.
This is to detect whether or not the copy sheet passing between the pressure roll 67 and the pressure roll 67 is discharged onto the discharge tray without being entangled between the rolls 66 and 67 by mistake. S ・
The T / S 165 is a temperature sensor for the fuser lamps 181 and 182.

(5-6) Billing Counter Next, a billing counter used for collecting a copy fee will be described with reference to FIG.

Since the base machine 21 of this embodiment can make copies of five colors, it has two types of bilinger counters. Among these, the main billing counter 211 counts the number of copies made regardless of black and white or color. The count value of this main billing counter 211 is
When the accessory 212 such as a coin kit or a key counter is attached to the copying machine, the accessory 212 is also used as data for count control. Sub billing counter 213
Is used to count the total number of colors used in each copy when color copies are made.

(5-7) Power supply Next, the power supply will be described with reference to FIG.

(5) Transport system Next, a transport system for copy sheets will be described with reference to FIG.

The first to fifth supply trays 31-1 to 31-5 include a no-paper sensor 231, a size sensor 232, and a clutch 233.
Are provided respectively. Where no paper sensor 23
Reference numeral 1 is a sensor for detecting the presence / absence of copy paper in the supply trays 31-1 to 31-5. In this copier, copy paper of the same size can be set in a plurality of supply trays. In this case, when copy paper of one supply tray runs out, copy paper of the same size is automatically supplied from another supply tray. Can be fed to The size sensor 232 is a sensor for determining the size of the copy paper stored in the tray. Also, clutch 23
Reference numeral 3 denotes a component for controlling on / off of driving of each of the feed rolls 61-1, 61-2,....

Dedicated feed motor for feeding copy paper
Performed by 235. A step motor is used as the feed motor 235. The feed sensor 236 detects whether the copy sheet is normally fed. The gate solenoid 237 is a registration solenoid for aligning the leading edge of the once fed copy sheet. The gate solenoid 237 performs control such that the gate is opened at the time of energization and passes the copy sheet, unlike a normal solenoid of this type.

That is, in a standby state in which no copy paper arrives, power is not supplied to the gate solenoid 237, and the gate remains open. Just before the copy paper arrives, the gate solenoid 237 is energized, and the gate closes to prevent passage. Then, the energization is stopped and the gate is opened at the time when the conveyance of the copy sheet is restarted at a predetermined timing. Such control reduces the fluctuation of the gate position when the leading edge of the copy paper is blocked and prevents the copy paper from being positioned even if the copy paper is pressed against the gate with a relatively strong force. Can be done accurately.

The manual feed switching solenoid 238 is the first feed tray 31-
1 is a solenoid for switching the drive of the conveyance roller of the copy paper fed from 1 and the conveyance roller of the copy paper fed manually from the manual feed tray 41. The manual feed tray sensor 239 is a sensor for detecting the presence or absence of copy paper when a plurality of copy papers are fed from the manual feed tray 41. The tray interlock 241 is

54 and a delivery paddle 255 are arranged, and these deliver the originals 251 one by one. Originals sent out 2
Numeral 51 denotes a drive roller 256 and a driven roller 257, which pass through an S-shaped transport section 258, and which are connected to the S-shaped transport section 258 and the vertical transport section
Is pressed against the branch guide 261 arranged at a position where the intersection with the branch guide 261. The branch guide 261 is thereby released, and the document 251
Are transported to the reverse transport unit 262 side.

When the trailing end of the document 251 passes through the branch guide 261, the branch guide 261 closes to the S-shaped transport unit 258 side by the action of a spring (not shown). At this time, the passage of the document 251 is detected by a sensor (not shown) arranged near the branch guide 261. This detection signal output causes the document reversing drive roller 264 to rotate in the reverse direction. As a result, the transport direction of the original 251 is reversed, and the transport direction is changed to a direction substantially perpendicular to the platen glass 55.

Thereafter, the document 251 is conveyed while being positioned by the skewed slip paddle 265 with one side thereof abutted on a side positioning guide (not shown). Then, the sheet is conveyed by the endless conveyance belt 266 to a correct position on the platen glass 55. In this manner, the copying operation on the first side of the document 251 is performed.

When the exposure on the first surface is completed, the original 251 is conveyed by the endless conveyance belt 266 in the direction of the arrow 267.
In the case where only the first side is copied by the operation of the exit side guide 268, the vertical transport unit 269 is selected, and the document 251 is stored in the document receiving unit 271.

On the other hand, when a copy is made on the second surface opposite to the first surface, the horizontal transport unit 272 is selected. The document 251 sent out to the horizontal transport unit 272 is transported in the direction opposite to the arrow 267 by the transport rollers 273, and is transported in the S-shaped transport unit 258 by the drive roller 256 and the driven roller 257. At this time, the lower surface of the original 251 is the second surface, which is the reverse of the time when the original 251 was stored in the original tray 252. Therefore, the original 251 is transferred to the platen glass 55 by the same transportation procedure as described above.
In this state, the copying operation for the second surface is performed.

After the exposure of the second surface is completed, the document 251 is sent to the vertical transport unit 269 by the action of the exit side guide 268 and discharged to the document receiving unit 271.

In the present system, coordinate input can be performed independently from the editor pad 132 or the console panel 28.

Input of coordinates from the console panel is performed by the ten-key pad 80 and directly read by the copying machine controller 121 including the main CPU 121.

Input from the editor pad is the coordinate input pad 405.
The original is placed face up and the coordinates are input by pressing two points on the diagonal of the quadrangle with a pen or the like. When the area is designated by the coordinates of each vertex of the polygon, the designation method button 419 (see FIG. 19) on the editor panel is operated to push each vertex. When the designation method button 419 is operated again, the mode returns to the input mode using two points on the diagonal of the quadrangle, and these area designation methods can be switched to each other. When the area is designated in this way, the editor pad CPU 129 (card CPU 1 in FIG. 6)
29 is also used) and converted into a predetermined signal and read by the copying machine controller 121. It should be noted that there may be a plurality of designated areas for each document (up to five areas in this embodiment).

The copy machine controller 121 includes paper selectors 106 and 107.
The paper size is input from (see FIG. 5), and the magnification is designated and input from a magnification setting key (see FIG. 5) including arbitrary magnification shift keys 101 and 102 and a fixed magnification setting key 103. The maximum value (coordinates of the vertices of a polygon) input in this way is multiplied by a scaling factor, and it is compared with the paper size to calculate whether or not the specified area extends from the paper. Input data, calculation of whether or not the area extends The result and the like are transmitted to the message display CPU 127 and the ISIL CPU 122 by serial communication.

The message display CPU 127 calculates the display data of the designated area from the received data, temporarily stores it in the built-in memory, and erases any data out of the paper range. The LCD 112 displays "Ready to copy" if there is no protrusion due to the calculation result from the copying machine controller 121, and "Cannot copy the entire document. Change the paper or magnification" if there is protrusion.

The CPU 122 for ISIL multiplies each coordinate data of the designated area from the received data by a magnification, and corrects the Y coordinate for ISIL to 2.4 mm pitch to calculate the output area of the ISIL 141. This is ISIL 2.4mm
It consists of 128 light emitting corners arranged in a line, and the erase control in the X direction, which is the carriage scanning direction, is performed by ON / OFF control of the light emitting diodes according to the scanning position. 2.4mm by the ON / OFF control of the light emitting diode for the extinction control in the Y direction perpendicular to
This is because it is done in units. The ISIL CPU 122 erases the data outside the paper range and controls the drive of the ISIL 141 to form an image of the data within the paper range.

(6-2) Area Extrusion Processing in Message Display CPU FIG. 22 is a diagram showing a graphic area of the message display memory, and the adjacent area is a character area. The graphic area is oriented in the same direction as the original surface.

In Fig. 22, 192 bytes of 96 bytes in the upper row and 96 bytes in the lower row are allocated to the graphic area.
Top 3 from 50 to 5F and ex from B0 to BF in ex display
The 45th bit is allocated as the graphic area with the bit position as the right reference position on the document surface. This is the biggest
A3 size is 420 mm and 42 bits, 2 bits are applied to this as a frame, and foreign paper 11 x 17 (inch) size is 432 mm
This is because 43 bits are allocated to this, and 2 bits are allocated to this for the frame.

Now, the paper is A4 portrait (the short side is the scanning direction), the magnification is 100%,
The input area is given as a rectangle and its diagonal vertices are (150,15
0) and (250,250). In the memory area on the message display, 10 mm corresponds to 1 bit, so A4
The addresses of the vertices of the vertical paper (297 mm, 210 mm) are (30, 21) and correspond to the 3rd bit of the 1B address. In addition, the addresses on the front right and back left of the input area are (15,15) and (25,25), (3rd bit of 91th address), (5th bit of 27th address).
Corresponding to. Thus, the A4 vertical area and the input area are set as shown in FIG. Next, for message display

Address-2A, 30-3A, 40-4A, 60-6F are all 0, 1B-1F, 70-
The upper 4 bits of address 7F are set to 0, and the upper 50 bits of addresses 50 to 5A are set to 0, and the protruding area is erased as shown in FIG.

As a result, as shown in FIG. 24 (a), the area designated as a diagonal line on the document surface is displayed as shown in FIG. 24 (b). In addition, ISIL
In 141, as shown in FIG. 24C, only the area within the sheet is imaged as an effective area.

(6-3) Message display in the area protrusion process When extraction is selected by the edit key and the protrusion occurs as described above, the protrusion portion is removed and displayed as shown in FIG. 25. The message "The entire document cannot be copied, please change the paper or reduction ratio" is displayed. Therefore, the user knows that the designated area is out of the way, and can take a measure such as making a copy or changing the paper or changing the reduction ratio.

As shown in FIG. 26, if a portion outside the sheet that has been subjected to the protrusion processing is also displayed by a broken line or the like, it is possible to know at a glance how much the protrusion is, and it is easier to take measures.

FIG. 27 shows a case where the delete key is selected with the edit key. Similar to the case of extraction, the portion excluding the protruding area is displayed and the same message is displayed.

FIG. 28 shows a state in which the protruding area is reduced so that it does not protrude. The message display in this case is from the display shown in FIG. 29 (a) to FIG. 29 (b). As shown in, the display will change to a graphic display in which the area is contained in the paper and a "copy ready" display.

Fig. 30 shows the case where the designated area has overflowed due to the enlargement of the magnification. In that case, the message "Copy is possible" to "The entire document cannot be copied ..." is displayed contrary to Fig. 29.

FIG. 31 shows a message display when the paper is changed due to the area protruding.

FIG. 32 shows an example of graphic display in editing. The copying machine of the present embodiment can display a maximum of 5 areas. When a plurality of areas are designated, even one of them has a protruding area. If so, the message is displayed as described above.

The processing flow of SIL CPU is shown respectively.

In the main body CPU, as shown in FIG. 33 (a), when the edit input is completed, the main body CPU transmits the edit data to the message CPU 127 and the ISIL CPU 122 by serial communication (step,). Further, the maximum value of the edit area such as the vertex of the polygon is multiplied (step), and it is determined whether or not the converted area extends from the paper (step).
Then, if it sticks out, send the display data of "It sticks out of the paper. Please change the paper or the reduction ratio", and if it does not stick out, the display data of "You can copy" is sent to the message CPU by serial communication. . Then, when the paper is changed or the magnification is changed (step,), the step is returned to the step again, and the determination as to whether or not the sheet protrudes is performed again. Then, the copy operation starts in step.

In the message CPU, as shown in Fig. 33 (b), when editing data is received by serial communication (step), each coordinate data is multiplied by 1/10 and each coordinate value is reduced to 1/10 according to the graphic memory area. , Calculate the display data in the graphic memory area (step,
). Then, as described above, the data outside the paper range is cleared (step) and displayed together with the calculation data.

In the ISIL CPU, as shown in Fig. 33 (C), when the editing data is received (step), each coordinate data is similarly multiplied (step), and as described above, ISIL
For correction, the Y coordinate is changed to 2.4 mm pitch, and the output area data of ISIL is calculated to form an image (step). Note that IS
The process of erasing the protruding part in the ILCPU is performed when the LED on / off data is actually sent to ISIL after the start of copying.

(6-5) Relationship between paper type and graphic memory area Figure 34 shows the relationship between paper (vertical) type and message display memory area, 420 mm (42 bits), 297 m for A3.
m (30 bits), B4 is 364 mm (37 bits), 257 mm
(26 bits), 297 mm (30 bits), 210 mm for A4
(21 bits), 257 mm (26 bits), 182 mm (1
9 bits), and this size is allocated to the memory area.

In the case of landscape paper, the memory area can be similarly assigned.

(6-6) Overflow Processing in Continuous Shooting Color Composition FIG. 35 shows the overflow processing in continuous shooting color composition, as viewed from the ISIL side. In the continuous shooting color composition described here, the extraction area is specified in the extraction area (the right-side original when the area is specified) and the extraction area is not specified in the right-side area (the left original when the area is specified) in FIG. In the case of full color, the area is projected as shown in the figure.
In the second copy, the left side area excluding the protruding portion as shown in Figure 35 (b) is copied, and in the second copy the right side area is copied in full color, as shown in Figure 35 (c). You will get a copy.

In this case, if A4 landscape paper is used, the center of the document will be the second bit at addresses 20 to 2F and 80 to 8F on the graphic memory, as shown in FIG. 36.
00 ~ 0F, 10 ~ 1F, 60 ~ 6F, 70
The area of addresses 7 to 7F is set to 0, and addresses 20 to 2F and 80 to 8F are erased leaving the lower 2 bits. Also, when using B5 landscape paper, the center of the document should be from 30 to 3F, 90
Since it is the 7th bit of the address to the 9F address, the same processing may be performed at this point. However, the areas at addresses 30 to 34, 40 to 44, and 50 to 54 must also be set to 0.

FIG. 37 shows a display on the graphic display surface (the same as the original surface), in which the protruding portion is erased on the left side and only the right extraction area of the original is displayed.
