Description

The present invention relates to an image forming apparatus that selects a function by displaying a plurality of functions as options on a display unit, and displays the function when the selection is completed. The present invention relates to an execution function display method suitable for a recording apparatus for recording image information, such as a copying machine, a facsimile apparatus, or a printer, which has multiple functions and is selectively used.

[Conventional technology]

In recent years, with the spread of copiers, user requirements have diversified, and copiers with more functions and sophistication have been developed and appeared in response to the diversification. A relatively new function provided by a copying machine is, for example, a 1% copy reduction ratio of a document.
A function that can be set arbitrarily in increments, a multicolor color copying function using two or more types of toner, a single color copying function using a selected color, and a double-page spread of a bound original without moving the original
A continuous page copying function that successively copies pages one by one, a two-sided copying function that automatically copies both sides of a document continuously or automatically on both sides of a sheet, and combines or deletes multiple documents. There is an editing function for editing and copying, a job memory function for storing copying conditions in an IC card and automatically setting the copying conditions by reading the copying conditions, and an extremely large number of other functions as described later.

The trend toward multifunctionality and sophistication of such apparatuses is common to recording apparatuses that record image information, such as facsimile apparatuses and printers, as well as copying machines.

By the way, even if the device is multifunctional as described above, all of the functions are rarely used, and rather, depending on the type of business or place where it is used, some of the functions are used in a biased manner. Normal. For this reason, conventionally, there has been adopted a supply system of a device that prepares a dedicated model combining various functions from a high-end model having various functions so that a user can select a model that meets a request. In some cases, additional devices are selectively mounted in response to a user's request to satisfy the user's request.

In any case, it is necessary to select those functions due to the multifunctionality of the device. For this purpose, conventionally, switches and buttons for selecting usable functions,
Operation functions such as keys, and a display mechanism such as a display panel and a display lamp are provided on the console panel, and a desired function is selected from several functions that can be used one by one using the operation mechanism on the console panel. It can be started.

[Problems to be solved by the invention]

By the way, as the device becomes more multifunctional and sophisticated as described above, generally, it should be possible to provide a device that is more convenient and has a wider range of use, but on the other hand, it has various problems. For example, by providing various dedicated models, as the number of models increases, it becomes more difficult to reduce the manufacturing cost and the apparatus becomes expensive. Even if there is a special model with a combination of various functions, the user often has the functions required by the user, but there is no model with only that function, and extra functions are added There are many. Providing a useful device to the user and operability by enabling the user to easily select and confirm the desired function among the devices having such extra functions and to quickly operate the device. Improvements are required.

In particular, when the device becomes multifunctional, a mechanism for selecting a function is required for each function, and the operation panel has various operation mechanisms such as various switches, keys, and buttons. Therefore, when many functions are incorporated in one copying machine, there is a problem that the copying machine becomes large in size and becomes complicated in terms of mechanism or operation, and operation errors are likely to occur, making it difficult to make full use of the apparatus.

For example, in a copier equipped with an automatic document feeder for two-sided copying and an intermediate tray, even if the correspondence between the document and the copy (two-sided function) is taken, from one-sided document → one-sided copying, one-sided document → two-sided copying, two-sided document → one-sided Four patterns from copy, double-sided document to double-sided copy can be used. Further, the provision of the intermediate tray also enables color marking, copy color composition, partial color conversion, sheet composition, parallel composition, and the like. Of course, some of these functions require the addition of an additional device. However, the provision of the automatic document feeder and the intermediate tray makes it possible to use these functions. In other words, the device must be operated by appropriately selecting a function to be used from among these many functions. When an operation mechanism is provided for each function, switches, keys,
If buttons and the like are provided, the number will be quite large.

Therefore, when trying to select a function by a combination operation of the operating mechanisms, there is a problem that the number of operation steps also increases in the function selecting operation, the operating procedure becomes complicated, and it is difficult to correspond to the selection operating mechanism. In such a case,
In the copier, a function different from the intended function is selected,
Useless copies increase, resulting in an uneconomical device.

SUMMARY OF THE INVENTION The present invention is directed to solving the above-described problem, and it is an object of the present invention to avoid erroneous recognition and erroneous operation of a function that cannot be executed by an attached additional device when a plurality of additional devices are attached.

[Means for solving the problem]

Therefore, the present invention, by attaching one or both of the first additional device and the second additional device,
In an image forming apparatus capable of performing a function corresponding to each of the additional devices, a first identification unit that identifies whether the first additional device is attached and the second additional device are attached. A second identification unit for identifying whether or not the first additional device is attached, when the first identification unit identifies that the first additional device is attached;
First display means for displaying a function corresponding to the additional apparatus, and when the second additional apparatus is identified as being attached by the second identification means, A second display unit for displaying a corresponding function, and the first identification unit and the second identification unit identify that both the first additional device and the second additional device are attached. And a third display unit for displaying a function corresponding to a combination of the first additional device and the second additional device when the operation is performed.

[Action]

According to the present invention, when the DADF capable of reading a double-sided document and the intermediate tray capable of performing a double-sided copy are attached as a plurality of additional devices, the DADF is provided by the first identification unit. Whether or not the intermediate tray is attached is identified by the second identifying means, and whether or not the intermediate tray is attached is identified. And the first
In the display means, when the first identification means identifies that the DADF is attached, the two functions of "single-sided original → single-sided copy" and "double-sided original → single-sided copy" are provided as functions corresponding to the DADF. A function is displayed, and the second display means, when the second identification means identifies that the intermediate tray is attached, as a function corresponding to the intermediate tray, “single-sided document → single-sided copy” and “single-sided copy” The two functions of “document → double-sided copy” are displayed, and the third display means uses the first identification means and the second identification means to display the DA function.
When it is identified that both the DF and the intermediate tray are installed, the functions corresponding to the combination of the DADF and the intermediate tray are "1-sided original → 1-sided copy", "2-sided original → 1-sided copy", and "1-sided original → 2-sided copy". , And four functions of “double-sided original → double-sided copy” can be displayed. As described above, the present invention can display only functions that can be executed in accordance with the attached additional device.

〔Example〕

 Hereinafter, the present invention will be described in detail with reference to examples.

In this embodiment, a copier is an example of a recording device, and a description will be given of an execution function display method using icons on a console panel of the copier which is provided with a switch and a display for a selection operation. Prior to the description, a table of contents for the description of the present embodiment is shown. In the following description, (1)
Items (5) to (5) are for explaining the overall configuration of a copying machine to which the present invention is applied, and (6) describes an embodiment in which the execution function display method using icons according to the present invention is applied.

As shown in this figure, the function of the copying machine applied to the present invention can be improved by attaching a desired additional device to the base machine 21 as the most basic configuration. 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 A copying machine can be provided.

(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 of the copy sheet separately 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 is arranged on the platen for editing a document. 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 backlit type console panel 27 is configured such that a display plate on which a message fixed in a predetermined position in advance is selectively illuminated from behind with 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 constituted by 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 forms. 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 disclosed in, for example, Japanese Utility Model Application No. 61-081016 (Japanese Utility Model Application Laid-Open No. 62-1946) filed by the present applicant.
No. 34), "Multi-Sheet Feeder Copier".

(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) The second and third supply trays 31-2 and 31-3 and the intermediate tray 33. Here, the intermediate tray 33 is a tray for temporarily storing copied paper when performing multiple copies on one surface of a sheet or performing alternate 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, 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 the discharged copy paper.

Copy papers are usually stored in a discharge tray 37. In this system, a 10-bin sorter 38 and a 20-bin sorter 39 are prepared. Therefore, by setting one of these sorters, copies can be sorted for up to 10 or 20 distribution destinations.

As described above, in this copying machine 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
It is often appropriate to purchase a single unit. On the other hand, a customer who makes a large number of copies or a customer who requires a complicated copy operation often needs the intermediate tray 33 and the large capacity tray. As a means for realizing such various requests, 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 product desired by the customer is easily obtained, but also the possibility of installing new additional equipment teaches the customer the possibility of a new copying operation. This will greatly enhance the purchase of this copier system in promoting the evolution of office paperwork.

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

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 incorporated together with the function information of the present invention from the 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 copying 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 is 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-purpose building is provided with a copier shared by a plurality of companies, or a copier shared by different departments even within one 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 advanced 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 IC cards according to the usage of each person or each department, and the more people or departments who want advanced functions will bear more basic costs and utilize more functions. You should be able to do so. 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 do not need copy paper sorting have ICs that lack 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 copy agency runs a self-copy service shop 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 mode, sets it in a desired copying machine, and makes a copy by self-service.
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 recording can be performed, and the like can be determined by the IC card to be lent, and the type of use can be restricted, so that customers who are charged can be managed. Furthermore, since the actual copy operation such as the number of copies and the size of the used copy paper can be written on the IC card, billing becomes easy, and detailed services such as discounting copy fees to regular customers are also possible. .

As a third example, a service using an IC card storing a program for a specific user will be described. For example, at a patent office, when examining patent publications reduced by photoengraving, it is necessary to make the same copy as the original size.
There are jobs that make copies at a relatively large enlargement rate of 0%. Also, when preparing a drawing to be submitted to a government office, work to reduce or enlarge the original drawing in small steps is performed 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, some users (users) request to use the copying machine in a special use 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 the IC card, a copying machine having a function most suitable for the user can be realized.

For example, in the case of a patent office, by purchasing a dedicated IC card, in addition to the normal several types of reduced magnification,
You can easily select a reduction ratio of 200%. In addition, the reduction ratio can be set in a range requiring fine adjustment, for example, in increments of 1%. In addition, the resident's card issuance department can indicate the type of resident's card and the columns and items to be deleted on the display such as the liquid crystal display by operating keys such as a numeric keypad. By pressing, only the desired range of the original is copied, or only the necessary portion is edited and recorded.

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

In the copying machine of this embodiment, the DADF
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 mounted on the right side of the apparatus, and a 10-bin sorter 38 is mounted on the left side. The manual feed tray 41 is for manual feed, but is capable of setting a plurality of sheets at the same time and sequentially feeding the sheets.

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
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 arranged. 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. Also, a copier with a cleaner design that does not protrude from the ADF (automatic document feeder) or paper feed tray has been realized.

FIG. 4 schematically shows the 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, a light image of a document (not shown) placed on a platen glass 55 arranged on the upper surface of the base machine 21 is incident on the exposure location 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 location 54. This electrostatic latent image is developed by the developing device 59 to form a toner image. The toner image is on the photosensitive drum 51
Transfer corotron (transfer unit)
Pass near 50.

On the other hand, the copy paper 60 stored in the first supply tray 31-1 arranged in the base machine 21 or the copy paper 60 manually fed along the manual feed tray 41 is used.
Is sent out by the feed rolls 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 the transfer is a heat roll 66 and a pressure roll 67.
And heat-fixed. And 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 DADF is
24 are installed. 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 section of the DADF 24 is set on the upper surface of the platen glass 55 first. Then, when the copying is completed, the original is set again in the original receiving section in a state where the original is turned upside down, and thereafter the original is again fed onto the platen glass 55.

Further, in the copying machine of this embodiment, five trays 31-2 to 31-5 and 33 are mounted below the base machine 21, but instead 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 Japanese Utility Model Application No. 61-130320 (Japanese Utility Model Application Laid-Open No. 63-038152).
No.) “Display device” and Japanese Utility Model Application No. 61-066170 (Japanese Utility Model Application
No. 179792) in “Character display device” and the like. 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.

On the console panel 28, a menu display board 71 is disposed at the top thereof, and the respective panel portions 74 to 79 are provided.
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 an IC card, a magnetic card, and a floppy disk can be used as the nonvolatile memory. In this copying machine, 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. The (a) continuous page copying function is a function of dividing an original spread over two pages, such as a bound original, into two pages one by one in a spread state and sequentially copying the originals. 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 make it set. (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. (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.
v) When the single color switch 91 is selected, the original is copied in one color.

A copy density panel 77 provided below the portion where "copy density" is displayed on the menu display plate 71 has a display lamp 82 indicating which of the five levels of copy density 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.

An automatic density adjustment switch 97 is provided below the copy density panel 77.
Is arranged. When the automatic density adjustment switch 97 is pressed, the automatic density display lamp 98 is turned on to enter the moving density adjustment mode. In this automatic density adjustment mode, a part of the light that is reflected from the original and reaches the photosensitive drum 51 while the original is being scanned is extracted by a half mirror or the like, and the light in the developing device 59 is adjusted according to the amount of light. Of the developing electrode is set.

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.

The magnification display section 99
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 the desired magnification, use the shift keys 101 and 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.

In this type of conventional manual feed tray, manual feed is performed one by one. Therefore, when the manual feed is performed, the copy paper may be preferentially sent out from the manual feed tray, 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 set a plurality of copy sheets at the same time. Therefore, if paper is fed from the manual feed tray 41 with the copy paper set, the feed may be started when a plurality of copy papers are set. To prevent such a situation,
The selection of the manual feed tray 41 is performed.

(B) A3 paper display; Select when using the tray for feeding A3 size copy paper in the longitudinal direction.

(G) B5 landscape paper display: Select when using the tray for feeding B5 size copy paper in the direction perpendicular to the longitudinal direction.

(H) Non-standard paper display; Select when using copy paper of a size other than the above.

An automatic paper / magnification selection switch 109 is provided below the magnification / paper selection panel 78. This switch 109
When the button 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 a desired combination has been selected from the lighting state of the display lamp 82 on the magnification / sheet 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. A sentence including Chinese characters can be displayed on the liquid crystal display unit 112 of this embodiment. The example shown in FIG. 5 indicates that a copy 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 a basic state, that is, a priority mode which 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: This button functions as a clear button when copying is stopped halfway, when the number of copies is set, or when the bin of the sorter 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) display key 119; a key (return key) for setting at a position 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, by displaying a sentence mixed with Kanji and Kana on the liquid crystal display unit 112 to assist the application 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 the copying machine, it is expected that the software development by module design can be shortened, the wire harness and the like can be simplified, the cost can be reduced, and trouble can be easily handled.

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.

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 tray flows, the intermediate tray 33 has its own motor for conveying the copy paper, and complicated control is required such that the storage position of the copy paper stored in this tray 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) Single control of a 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. Further, the card CPU 129 can control an editor pad 132 not used in this embodiment. 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 copying machine with a control device such as a CPU or a so-called microcomputer is described in the IEEE paper "A Programmable Digital Control System for Copy" by Xerox's SIKANDAR SHEIKH.

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, if four sensors are arranged in one supply tray for detecting the paper size, and digital data is used for this processing, it becomes necessary to transmit 4-bit digital data from one tray to the main CPU 121. Not only will a total of up to 20 input ports be required, but also the number of connectors and the number of cables that make up the harness will increase. This is not preferable from the viewpoint of cost, reduction in size, and reliability.

Therefore, in the copying machine of the present 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
Are connected to the following units via

(Iv) RAM 121E; a random access memory for temporarily storing data 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 (NVW) 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;

Data and the like for grasping the use state of the copying machine such as a value can be cited. (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.

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 photoconductor drum 51, a charge corotron 52,
Inter image lamp 141, 4 types of sub developing device 59S
1 to 59S4, main developing device 59M, transfer corotron
50, Detack 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 performs development with red toner,
The second sub-developing device 59S2 is a developing device that performs development with blue toner. 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 a 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 adjacent portions of the light emitting diodes emit light, the plastic lens (not shown) is formed on the photosensitive drum 51. Therefore, care is taken that the light does not have an uneven intensity in those boundary areas. Further, 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 of the inter-image lamp 141 divided into 128 segments. 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 motor 164 is started when 0.2 seconds have elapsed after 0 contacts 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 suction operation of the vacuum 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 color type can be detected for each of the sub developing devices 59S1 to 59S4 by this sensor. 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 toner supply is necessary.

(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 increment switch 159 is a switch that is pressed when the operator wants to increase the amount of toner. When the increase switch 159 is pressed in a state where one of the sub developing devices 59S1 to 59S4 is selected, the toner of the corresponding sub developing device is increased. When the main developing device 59M is pressed in a 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 for detecting whether the toner is 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 is 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 development selection / solenoid 161 is excited until the red copying operation 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 denotes a position distant 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 protrusion of one cam is pressed most strongly against the first sub developing device 59S1. I do. Then, at this position, development is performed with the corresponding red color toner. However, since the main developing device 59M in the initial state in this device is adapted to be positioned close to the photosensitive drum 51, developing a color such as red, rather than being started immediately at time t _1, The operation is waited for one 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 operation by the first sub developing device 59S1 is completed, the above-mentioned five cams move for one _second from the time t2, and the main developing device 59M is moved when the protrusion of the monochrome cam is positioned by the lever. Is set on the photosensitive drum 51. Thereafter, monochrome development is performed.

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 sequentially selected in a predetermined order. After these operations 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. 7A 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, first, the main developing device
Since development with 59M is performed, there is no need to wait for one 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 sheet 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 adjustment of the amount of charge applied to the photosensitive drum 51, the amount of exposure of the image, and the adjustment of 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 17 is a sensor provided for detecting the size of a document.

(5-4) Fixing Device Next, the relationship of the fixing device will be described. Fixing device is
Shown in Figure 12.

In the base machine 21 of this embodiment, two types of fuser lamps, a main phaser 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 disposed at a position slightly biased to one end of the main fuser lamp 181. In the copying machine of the present embodiment, a so-called corner registration (corner registration) method is adopted in which the copy paper 60 is positioned in accordance with one side of the platen glass 55, so that the size of the copy paper 60 to be used is The required amount of heat energy in the axial direction of the heat roll 66 differs depending on the heat roll 66. 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. Sub fuser lamp 182
, It is possible to sufficiently prevent the temperature unevenness of the fixing device.

The fixing device includes a fuser outlet sensor 184 and an STS
(Soft touch sensor) 185 are both connected. Here, the fuser outlet sensor 184 is connected to 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.
T · S165 is a temperature sensor for the fuser lamps 181 and 182.

(6) Function selection and display (6-1) Additional device and additional function As described above with reference to FIG.
There are switches to select various functions (83-86)
And an indicator lamp 82 for displaying the presence or absence of selection of these switches.
To 86) belong to a plurality of functions, and the functions that can be selected by the operation differ depending on what is attached as an additional device. The copying machine according to the present invention includes a DADF 24, an intermediate tray 33, and an IC card device.
Although 22 and the like can be equipped, these are attached as optional additional devices according to the user's request. Therefore, when these additional devices are attached, new functions that cannot be used in the base machine can be used, and the combinations of the usable functions also differ.

For example, when the DADF 24 is attached, both sides of the document can be continuously exposed. That is, the first exposure is performed by transporting the document such that one side of the document faces the platen glass, and after the exposure is completed, the document is turned over and the document is returned to the tray of the DADF 24. Then, by sending out the original again, it becomes possible to perform exposure of the surface opposite to the previous exposure surface.

Also, when the intermediate tray 33 is attached, the copied copy paper can be stored here, and when storing the copy paper, the copy paper can be stored upside down, as well as the original front side. Can be stored again as a copy surface.

Therefore, the additional functions that can be used for the DADF 24 and the intermediate tray 33 differ depending on whether one of them is installed or both. For example, from the aspect of the duplex function, only the DADF24 can use the double-sided original → single-sided copy function, and the intermediate tray 33 only can use the single-sided original → double-sided copy function. In this case, three additional functions of double-sided original and double-sided copy can be used. To select these functions, the double-sided switch 86 is operated. Also, from the point of view of the editing function, if there is neither the DADF 24 nor the intermediate tray 33, editing processing such as sheet combining or parallel combining cannot be performed, but if the intermediate tray 33 is provided, sheet combining becomes possible, and if the DADF 24 is added, Parallel composition is also possible. When selecting these functions, the edit switch 86 is operated. In this way, DADF24 and intermediate tray
The combination of additional functions that can be used in the example of whether or not there is 33 will be variously changed.

It should be noted that the sheet composition in the editing function is a function of recording both the first document and the second document as a whole on one copy sheet. In the copying machine of the present embodiment, the first original can be designated as an area of up to five areas, and the first original and the second original have different single-color color switches 91 respectively.
It is also possible to make copies in different colors using (FIG. 5). On the other hand, the parallel composition is a function of creating a composite copy on one copy sheet in a state where the entirety of the second original is attached to the entirety of the first original. Manuscript is ADF23 or DAD
Sent from F24. Therefore, a copier not equipped with these functions cannot use this function of parallel composition.

Further, in the copying machine according to the present invention, as described above, the random access data backed up by the battery is provided.
A non-volatile memory including a memory is provided, and copy conditions such as image density and magnification can be preset and stored in the non-volatile memory. When recalling or registering the preset storage contents, the job memory switch 84 is operated, but there is an IC card corresponding to this nonvolatile memory, and the IC card device 22 is used as an additional device. is there. The IC card device 22 writes the data of the standard copying business to the IC card, and supplies the data of the standard copying business from the IC card to the base machine, thereby automating complicated copying business, for example, for each type of business or each user. This ensures that the operation of the functionalized copier can be performed without fail. For this reason, the IC card contains the number of copies, continuous copying, reduction ratio, binding margin, left binding, right binding, copy density, and the selection information of the editing function and double-sided function in the predetermined format. Can be written from the IC card device 22 so that the device can be operated in a fixed form. Therefore, when the user carries the IC card and performs the standard copy, the IC card device 22 reads the information of the IC card, thereby automatically performing the standard copy operation without performing complicated operations on the console panel. Can be executed. Even when such an IC card device 22 is provided, the usable contents of the job memory function differ.

As described above, if various additional devices can be attached to the base machine, and the additional functions that can be used differ depending on the combination, a function that can be used by the user and a function that cannot be used cannot be easily distinguished, and confusion occurs. Come. Therefore, in order to eliminate such confusion, functions that cannot be used are not displayed, and can be used so that a desired function can be easily selected and used within a range of additional functions that can be used without being aware of the presence or absence of an additional device. By displaying only the functions in an easy-to-understand manner, a device with good operability can be provided. As the display means, the liquid crystal display unit can display character strings and icons (pictograms, image characters). By using the icons for the function display, it is possible to perform display that is easy for the operator to distinguish with little information based on pictorial information.

(6-2) Configuration of Function Selection System FIG. 21 is a diagram showing a configuration example of a function selection system using a liquid crystal display capable of displaying a message, and FIG. 22 is a diagram showing a configuration example of a display controller. .

In FIG. 21, the main controller 501 includes a main CPU 121, a ROM 121D, a RAM 121E, an I / O
It is composed of controllers 121J, 121G, etc., and has a function (program) for determining the presence or absence of an additional device. The function of determining the presence or absence of the additional function is to determine whether the DADF 24, the intermediate tray 33, and the IC card device 22 described above are provided, for example, in a connector that connects each additional device to the main body. A signal line which is turned on when the connector is connected is provided, and this signal is supplied to the filter circuit shown in FIG.
It is taken into the main controller 501 via 121H and the ROM
The determination process is performed by the determination program stored in 121D. Such a means for determining the presence or absence of the additional device is not a signal based on the presence or absence of the connection of the connector as described above, but, for example, a contact signal of a switch that is pressed and turned on when the additional device is mounted or a contact signal of a proximity switch. Needless to say, a signal from an optical sensor in which light from the light emitting unit is detected by the light receiving unit when the additional device is provided, or other signals may be used. In the main controller 501,
In this way, the DADF 24, the intermediate tray 33, the IC card device 22
Is determined. Further, the main controller 501 has a message transmission table for displaying guidance of each function selection and copy condition setting according to operation of a function selection switch, a key, and the like.
Function selection switch (double-sided switch 86, edit switch 8
3. When the job memory switch 84 and other switches 85) are operated, the message transmission table is determined according to the presence or absence of the additional device, and the designation information such as the presence or absence of the function information, the size of the binding margin, the number of copies, etc. Is set, and the data of the message transmission table is sent to the display controller 502. The display controller 502 includes a display CPU 127, a ROM 503, a RAM 504, and a serial interface 505 as shown in FIG. 22, and includes a module for processing data of a message transmission table, a text corresponding to each message transmission table, characters and icons. The font is stored in the ROM 503. Then, according to the data of the message transmission table received from the main controller 501, the text is read from the ROM 503, the designated information is set in the text, characters and icons constituting the text are developed into fonts, the LCD driver 506 is controlled, and the liquid crystal display is performed. A predetermined message is displayed in the unit 112.

Specific examples of sentences will be described later. For example, when selecting a function, a message character string “Which item do you want to select?” Is displayed, followed by an icon of a key (selection key or setting key) to be operated. , An icon and a character string (option) of a function to be selected, and a cursor icon. In a state where such a sentence is displayed, when the operator operates the selection key 118, the main CPU 121 recognizes this and counts up the designation information of the cursor position in the message transmission table. As a result, the cursor is shifted to the next position in the list of functions to be displayed. When the setting key 119 is operated, the main CPU
121 recognizes this and selects a function corresponding to the cursor position of the message transmission table, and determines a new message transmission table corresponding to the selected function. When copying is possible in this manner, a message transmission table of a sentence having a message character string “can be copied” is determined. Here, when the user sets the numerical values such as the set number of sheets and the margin and operates the start button 117, a copy operation under the selected function and desired copy conditions is started.

(6-4) Configuration of Message Transmission Table and Transmission Data FIG. 25 is a diagram showing a configuration example of the message transmission table. The serial transmission data shown in FIG. 24 is serial data generated based on the message transmission table shown in FIG. 25 and is managed by the main controller 501.
The information is classified by “STATE”, “SUBSTATE”, and “CASENO.”, And the content of “SENTENCE” is the content actually displayed on the liquid crystal display unit 112.

In the main controller 501, one of the message transmission tables is selected by operating various switches on the console panel 28. For example, the message transmission table shown in FIG. 25A is selected when the job memory switch 84 is operated. Then, the details of the transmission data are transmitted to the display controller 502 through the communication line. The message transmission table shown in FIG. 8B is selected when the editing switch 83 is operated. As described above, when the message transmission table is selected by the main controller 501 by operating the function switch and the message data is transmitted to the display controller 502, the corresponding text is read out by the display controller 502 and expanded into a font. Is displayed on the liquid crystal display unit 112. The function is selected in accordance with the displayed text (message). In the selection process, when the selection key is operated, the contents of the cursor in the message transmission table are shifted one by one. When the setting key is operated, the function at the position of the cursor is selected, and a message transmission table as shown in FIG. 25 (c) is selected as the next step. This message transmission table displays the text "Can be copied", erases it with the right binding, displays an icon indicating that the single-sided → double-sided function is selected, and sets the size of the margin and the number of copies. It is the content which prompts the input of.
When these contents are transmitted as serial data from the main controller 501 to the display controller 502, "SE
Special code (○ G) at the position of information specified in the free data area such as function icons and numerical values in the contents of “NTENCE”
A sentence in which an asterisk (*) is written is read out, and the special code or asterisk is rewritten with the information specified in the free data area and displayed on the liquid crystal display unit 112. In order to perform such processing, the display controller 502 stores the display control program, the text data based on the code, and the font data in the ROM 503 as shown in FIG. After reading the sentence data and further embedding the icons and numerical values therein, each of the sentence data is developed into a font.

(6-5) Icon and Font Data FIG. 26 is a diagram showing an example of an icon used in the present invention. These icons are represented by 16 × 16 dots. For example, (a) is an icon indicating an extraction function, (b) is an icon indicating a deletion function, (c) is an icon indicating a partial color function, and (d) is an frame. An icon indicating the erase function,
(H) is an icon indicating a cursor, (i) is an icon indicating a memory reading function, (j) is an icon indicating a memory registration function, (k) is an icon indicating a left margin, and (l) is a left margin. This is used as an icon indicating the right. As described above, when displaying the message, the options, and the selected function on the liquid crystal display unit 112 as a text, by using such an icon in the text, it is less than displaying only the character string. Necessary guidance information, confirmation information, and the like can be promptly and reliably transmitted to the operator based on the information amount and the display area.

FIG. 27 (a) shows an example of the font of the sheet composition icon, FIG. 27 (b) shows an example of the font data, FIG. 27 (c) shows the font of the kanji "shrink", and FIG. An example is shown. This font is composed of 16 × 16 dots, and the font data is expressed in hexadecimal by dividing one line of 16 dots into eight half dots. Kana, alphanumeric characters, and other icons can also be represented in 16x16 dot font and represented in hexadecimal.

(6-6) Processing Block Configuration of Main Controller and Display Controller FIG. 28 is a diagram showing a configuration example of functional blocks in the main controller 501 in display selection of an additional function, and FIG.
The figure shows a configuration example of functional blocks in the display controller 502.

In FIG. 28 showing the functional configuration of the main controller 501, an additional device recognizing unit 511 recognizes an additional device presence / absence determination signal and a function selection switch operation signal, and the function selecting unit 513 includes an additional device recognizing unit. 511 signals and select key 118 and setting key 1 provided on the console panel
The function is selected in accordance with the operation of 19. The text number determination unit 512 has a message transmission table managed by the text number, and determines the text number to be displayed on the liquid crystal display unit 112 based on the signal of the additional device recognition unit 511 and the signal of the function selection unit 513. . The message transmission table is prepared in two hundred and several tens of sentences as shown in FIG. 26 and FIG. 27 corresponding to the display mode for selecting a function and the display mode for executing copying and other functions. Therefore, when the function selection switch is operated on the console panel, the sentence number is determined from the operated function selection switch. For example, the text (a) shown in FIG. 26 is a text determined when the job memory switch 84 is operated, and the text shown in FIG. 26 (b) is determined when the edit switch 83 is operated. Is a sentence. Function information set section
Reference numeral 514 sets function information for the text determined by the text number determination unit 512. For example, when the text number shown in FIG. 28 (a) is determined by operating the job memory switch 84, the presence or absence of the IC card device 22 is checked. To a flag of "1". Similarly, when the text number shown in FIG. 22 (b) is determined by operating the edit switch 83, the presence or absence of the intermediate tray 33 and the DADF 24 is checked. Flag "1" in the column. In the transmission buffer 515,
The message transmission table of the sentence number determined by the sentence number determination section 512 is set, and the function information section therein is set by the function information setting section 514 and transmitted to the display controller 502.

In FIG. 29 showing the configuration of the display controller 502, a reception buffer 516 sets data of a message transmission table received from the main controller 501. The text data file 517 is stored in the liquid crystal display unit 112.
The text file (character string and icon) to be displayed is stored in the font file 519. The font file 519 stores fonts of characters and icons constituting the text data. The display control unit 518 processes the data of the message transmission table set in the reception buffer 516, and expands the display font in the display buffer 520. SUBSTAT
Predetermined text data is read from the text data file 517 based on “E” and “CASENO.”, And the specified information is embedded in the text to expand the font in the display buffer 520. Depending on the text data, it is necessary to perform a content rewriting process or the like based on the information set each time. For example, a function display, a binding margin, a set number of sheets, a cursor, and the like are included. In each piece of text data, a special code or an asterisk is set in advance at a position where such information is written. Therefore, in the display control unit 518, the sentence data file 5
When a sentence is read from 17, the special code or asterisk is blanked and the position is stored at the same time, and an icon or a numerical value is written to the position according to the designated information of the reception buffer 516. LCD display
At 112, the contents of the display buffer 520 in which the writing process of the character string and the icon is performed and the font is developed are displayed.

(6-7) Selection Display Process Next, a description will be given of a function selection performed when each of the function selection switches is operated and a display process therefor.

FIG. 30 is a diagram for explaining a processing flow when the double-sided switch is operated.

When the double-sided switch 86 on the console panel is operated, first, it is checked whether the DADF 24 and the intermediate tray 33 are attached.

If you have both the DADF 24 and the intermediate tray 33, use
You can choose from three functions: 2-sided copy, 2-sided original → 2-sided copy, 2-sided original → 1-sided copy. The message string “Which item do you want to choose?” Is determined, a message transmission table of a sentence composed of the above three functions to be selected, and a cursor indicating the selected position of the function is determined, and the sentence is displayed on the liquid crystal display unit 112.
Therefore, when this is displayed, move the cursor to the position of the desired function with the selection key 118, and then
119 will select that function. Normally, when a function is selected here, a message of "can be copied" is displayed next, and the operation shifts to a copy operation by the selected function.

However, if there is a DADF 24 but no intermediate tray 33, the function of double-sided document → single-sided copy is decided,
Also, if there is no DADF 24 but there is an intermediate tray 33, the function will be determined as one function of single-sided original → double-sided copy, so a message transmission table of text that contains the content that prompts you to set “can copy”, function, and number of copies Is determined, and the sentence is displayed on the liquid crystal display unit 112. Therefore, in this case, when a document is set, the number of copies is input from the numeric keypad 80, and the start button 117 is operated, a copy operation according to the function is started.

As described above, when the double-sided switch 86 is operated,
The message transmission table of the sentence shown in (1) or the message transmission table of the sentence shown in (2) is used.

FIG. 31 is a diagram for explaining the flow of processing when the edit switch is operated.

When the edit switch 83 on the console panel is operated, first, it is checked whether or not the ADF 23 or DADF 24 is present and whether or not the intermediate tray 33 is present.

If there is any of ADF23 or DADF24 and the intermediate tray 33, 4 of extraction, deletion, sheet composition, and parallel composition
You can use one of the three functions. The message string "Which item do you want to use?", An icon indicating that the selection key and setting key are the next operation key, and the choices of four functions to be selected Then, a message transmission table of a sentence composed of a cursor indicating the selected position of the function is determined, and the sentence is displayed on the liquid crystal display unit 112.

However, if there is no intermediate tray 33, both the sheet composition and the parallel composition cannot be used, so that the message transmission table of the same sentence is determined, and the function information for deleting the option of this function is set. . Therefore, a sentence in which extraction and deletion are options is displayed.

Similarly, if there is an intermediate tray 33 but neither ADF23 nor DADF24, the function of parallel composition cannot be used, so the function information for erasing the option of this function is set, and a text with options of extraction, deletion and sheet composition is set. Is displayed.

When the edit switch 83 is operated in this manner, 4
Only the difference in the set of function information for one option is determined, so the message transmission table of the same sentence is determined,
By selecting a desired function by using the selection key and the setting key on the message display, the process proceeds to the next step.

FIG. 32 is a diagram for explaining the flow of processing when the job memory switch is operated.

When the job memory switch 84 on the console panel is operated, first, it is checked whether or not the IC card device 22 is present.

If YES, that is, if there is an IC card device 22, the card registration function can be used, so select "Which item do you want to select?", And confirm that the selection key and setting key are the next operation keys. A message message transmission table including an icon to be displayed, three choices of “call”, “registration”, and “card registration” to be selected, and a cursor indicating a selected position of a function is determined, and the text is displayed on the liquid crystal display unit 112. Is displayed.

However, in the case of NO, that is, when the IC card device 22 is not attached, the message transmission table of the same sentence as described above is determined, and the function information for deleting the option of this function “card registration” is set. You. Therefore, a sentence having options of calling and registration is displayed.

(6-8) Processing by Main Controller and Display Controller FIG. 33 shows in detail the flow of processing in the main controller 501 when the edit switch is operated.
FIG. 34 shows the flow of processing in the display controller 502 in detail.

First, the flow of processing by the main controller 501 will be described with reference to FIG. When the edit switch 83 is operated, a message transmission table for selecting a function is set in the transmission buffer.

Next, it is checked whether the signal indicating the presence or absence of ADF23 or DADF24 is on (present).

In the case of NO in the above processing, information indicating that the option of "parallel combination" is deleted is set in the transmission table.

In the case of YES in the above processing, or after performing the above processing, it is checked whether or not the signal indicating the presence or absence of the intermediate tray 33 is ON (present).

In the case of NO in the above processing, it is a sentence used in color conversion for the transmission table. FIG. 35 (c) shows an example of a display screen in which icons and numerical values are written in these sentences.

Next, examples of sentences used when each function selection operation is performed will be described.

FIG. 36 is a diagram showing an example of a sentence in the selection operation of the double-sided function.

When the double-sided switch 86 is operated, if there is the DADF 24, the single-sided → double-sided and double-sided switching is performed by equipping with the intermediate tray 33 as described above.

Further, it monitors whether or not the setting key 119 is operated, and when operated, sets the function of the option of the cursor position in the machine.

At the same time, set the message transmission table of the message number of "Can be copied" in the transmission buffer, and set the information indicating the set function in the transmission table.

Thereafter, the data of the transmission table is transmitted to the display controller 502 every 100 msec.

On the other hand, in response to the processing by the main controller 501, the display controller 502 performs the following processing (FIG. 34,
(See Fig. 25).

First, at the end of the reception of the serial data, the head address of the sentence to be displayed is obtained and this is copied to the RAM.

Next, the positions of the special code (G4) and the asterisk (*) are stored.

 Then, all the special codes are deleted.

Write data to the asterisk (*) position of 3RD # DGT and 4TH # DGT. If the data is 10, the number of copies is 10, and the number of copies is 10.

 Check whether $ 1 is "0".

In the case of YES, that is, when the binding function is not provided, four characters are deleted from the first asterisk.

Next, bits other than "0" are found for $ 2 to $ 8.

Icons are written in order from the first position of the special code corresponding to bits other than “0”. The example shown is $ 8
Indicates “3”, that is, the case of both sides → one side.

Then, the message text including the icon and the character string is displayed on the liquid crystal display 112.

In the above processing, when NO (with mm display), that is, when there is no binding function, 1ST # DGT, 2ND # D
Write the data to the GT asterisk (*). Hereinafter, processing similar to the above-described processing is performed.

As shown in FIG. 35, the message text stored in the ROM 503 of the display controller 502 includes kana, kanji, alphanumeric character strings, icons used for function display, etc., and special codes (○ G), consisting of an asterisk (*) at the numerical value writing position, and the message No.
It is read using the case number as an address. In addition, k has shown the Kasor position. Then, icons and numerical values are written in the positions of the special code and the asterisk according to the information in the free data area (FIG. 24) of the received data as described in FIG. In the case where the icon is used fixedly in the text, it goes without saying that the text may be composed from the icon code from the beginning without using the special code. Fig. 35 (a) shows an example of a sentence having the message "Can copy", a sentence having the message "Which item do you want to choose?" Fig. 35 (b) shows an example of the text of the message to be input, where MSG NO. (Message number) 7.1.28 is sheet composition, 7.1.31 is extraction, 7.1.32 is deletion, and 7.1.33. Is a button used for performing marking by setting a thick underlined area 17I as shown in FIG. 64.

(T) Color designation buttons 434 to 437; Since the color of the marking can be made independently for each area, this button is used to designate the color in relation to the area to be marked. Here, the color designation button 434 designates red, and the color designation button 435 designates blue. The color designation button 436 is green, and the color designation button 437 is a brown finger → both sides, both sides → one side can be used, so
As shown in FIG. 36, a sentence having all of these as options is displayed, and the cursor (triangle mark) blinks in front of the first option “single-sided → double-sided”. If the selection key is pressed here, the cursor moves to "double-sided → double-sided", and if the selection key is further pressed, the cursor moves to "double-sided → single-sided" and blinks. When the cursor is blinking in front of “double-sided → double-sided”, the text of pressing the setting key is displayed, and the copy mode is set. However, if there is no DADF24, the text of or will be displayed. Then, when the position of the cursor is selected with the selection key and the setting key is pressed while the text is displayed, or the text is selected and displayed.
