The present invention relates to an execution function display method by means of an icon which selects a function by displaying a plurality of functions on the display means as an option and displays the function when the selection is finished, and provides a multifunction and selective copying machine or facsimile apparatus; A display function of a prior function suitable for a recording apparatus for recording recording information such as a printer.

In recent years, with the spread of copiers, users' needs have diversified, and in response to the diversification, more multifunctional and advanced copiers have been developed and appeared. Relatively new functions provided by the copier include, for example, a function that can be arbitrarily set at intervals of 1% of the copy magnification ratio of a document, a multicolor color copying function using two or more toners, a single color color copying function by a selected color, and the original body itself. Lazy copying function that continuously copies two pages of two-page printing of a booklet original one by one page without moving the document, or double-sided copying function that automatically copies both sides of the document continuously or continuously on both sides of the paper. There are many editing functions for editing and copying by synthesizing or deleting originals, a narrow memory function for automatically setting copy conditions by storing the copy conditions on the IC card, and reading them.

The trend of multifunctionality and advancement of such a device is not limited to a copier, but is common to a recording device that records recording information such as a facsimile device or a printer.

By the way, even if the device is multifunctional as described above, the use of all of their functions is usually small, and it is common to use some of them by industry or place. Therefore, conventionally, the supply method of the apparatus which prepares the exclusive model which combined various functions from the high-end model which has the function suitable for the request by the user is employ | adopted. In some cases, additional devices are selectively installed in response to the user's request to satisfy the user's request.

In either case, it is necessary to select the functions of the devices by making the devices multifunctional, but in order to do so, a console or a display function such as a switch or a button for selecting a usable function, an operation mechanism of keys, and a display panel or display lamp is conventionally used. It is equipped with a renewed panel, and the operation functions on this panel are used to select a desired function from among several functions that can be used one by one.

However, when the device is multifunctional and advanced as described above, a device that is generally convenient and has a wide range of use will be provided, but it has various problems. For example, if a large number of models are provided by providing various types of dedicated models, it is difficult to reduce manufacturing costs, and the apparatus becomes expensive. Even in a dedicated model based on a combination of various functions, a user often has a function required by the user. However, there is no model having only the function, and an extra function is often added. Thus, it is desired to improve the operability of providing a useful device to a user by enabling the user to easily select and confirm a function to be used even in a device having an extra function.

In this case, a problem arises in that it is necessary to use a relatively expensive product and it is economical. However, it is necessary for each user to be able to provide a device by a combination of functions suited to the demand. In addition, when a large number of functions are stacked in one copier, the copier becomes large and becomes a complicated device on the surface of the machine or on the operation surface, and thus there is a problem in that it is easy to cause an operation error and becomes difficult to use well.

In particular, when the apparatus becomes more versatile, a mechanism for selecting a function for each function is required, and an operation mechanism such as various switches, keys, buttons, etc. is increased on the operation panel. Therefore, even in the function selection operation, there is a problem that the operation step is also increased, making the operation procedure complicated and making it difficult to cope with the selection operation mechanism.

SUMMARY OF THE INVENTION The present invention solves the above problems, and furthermore, a display device having an additional function that makes it easy to understand the selection and setting by the configuration of the same operation panel even if the operation mechanism such as a switch or a button on the operation panel is small and the usable functions are changed. It aims to provide.

In particular, when the device becomes multifunctional, a mechanism for selecting a function is required for each function, and an operation mechanism such as various switches, keys, and buttons is increased on the operation panel. Therefore, when many functions are stacked in one copier, there is a problem that the copier is enlarged, becomes a complicated device in terms of mechanism or operation, and is difficult to be easily manipulated and used completely.

For example, in a copying machine equipped with an automatic document transfer device and an intermediate tray for copying, even if the correspondence between the originals and the copying (two-sided function) is taken, from one-sided document → one-sided copy to one-sided document → two-sided copy, two-sided document → two-sided copy Patterns can be used. In addition, by providing an intermediate tray, color marking, continuous color synthesis, partial color conversion sheet synthesis, parallel synthesis, and the like are also possible. Of course, some of these functions require the addition of a device for this purpose, but by providing the document automatic transfer device and the intermediate tray, this function can be used. In other words, among these many functions, the user must select the function used by the enemy to operate the device, and if a control device is installed corresponding to each function, the number of switches, keys, buttons, etc. increases significantly.

Therefore, attempting to select a function by the combination operation of the operation mechanism has a problem that the operation step increases in the function selection operation, which complicates the operation procedure and makes it difficult to cope with the selection operation function. In such a case, the copier selects another function that is intended, resulting in more useless copies and an uneconomical device.

The present invention solves the above problems and aims to provide an execution function display method by an icon that can display an easy execution function when moving to execution by performing a predetermined function selection operation, thereby eliminating the useless operation of the device. It is.

For this reason, the execution function display method by the icon of the present invention displays a plurality of functions as an option on the display means, and selects a function and displays the function when the selection is completed. Display means 11 capable of displaying the fonton of the display device; memory 12 having stored therein information on the position of writing the icon of the execution function and the execution function icon; and reading out the sentence from the memory 12 in response to a function selection operation, and expanding the display means into fonts A function selecting means 13 for displaying on the screen and selecting a function by setting input, and a display control means 14 for reading out sentences from the memory 12, expanding them into fonts and displaying them on the display means when selection is completed by the function selecting means. have. Here, the function selecting means 13 reads out and displays the sentence of the selection menu, which is a character string or an icon, from the memory 12 when the instruction input is a function selection instruction by an operation of a switch or the like, and selects a function if there is a setting input according to the display menu. For example, when a double-sided switch is selected, a sentence having a selection function such as double-sided original → double-sided original, double-sided original, double-sided copy, double-sided original → single-sided copy, etc. is read out from the memory 12. If you select the function of one-sided document → two-sided copy, select the function. The display control means 14 reads an execution sentence such as "can be copied" from the memory 12 when the function is moved to execution by this selection, and adds a function to execute the sentence, and an icon of one-sided document to two-sided copy.

In addition, the call selection method according to the function selection of the present invention is composed of a Chinese character, an alphanumeric string and an icon (pictogram, image character) and a symbol as shown in FIG. A memory 12 which stores fonts of the constituent characters and icons, a sentence display control means 14 which reads a sentence from the memory 12, rewrites the position of the carousel in the sentence according to the input of the setting key, and expands the sentence into a font; and Display means 1 capable of displaying a character string and an icon font, and displays a message of function selection and a plurality of functions to be selected as an option by operating a function selection key, and simultaneously displays and selects a Kasol icon on one of the choices. When the key is operated, the display position of the icon is moved to the next option. When the setting key is operated, the display of the icon is displayed. Select the function of the choices in the. Therefore, the group of functions displayed on the display means 1 as an option on the lever is selected by one operation of the function selection key, and the selection is designated by the selection key within the display range, and the selection decision of the function is performed by the setting key. Is done.

In addition, the display selection device of the additional function of the present invention is a device having a structure in which a plurality of additional devices can be attached. And display means for expanding and displaying the set data setting means and the set display data in a font. In this case, the data setting means has a message table file, and a message table corresponding to the presence or absence of all attachable additional devices and a menu for displaying and selecting the available functions are stored.

Further, the data setting means reads out the message table by the combination of the presence or absence of the additional device and the operated switch, and if there is a function that cannot be used in the setting process of the display data, the data setting means eliminates this display.

In the execution function display method according to the icon of the present invention by providing the above means, if the function selection operation is performed using an operation mechanism such as a switch, a key, or a button disposed on the console panel, the function of editing or double-sided function selection The sentence of the selection menu corresponding to the content is read out from the memory by the function selection means. By the way, when the instruction input of the function selection is made in accordance with the displayed menu, the execution function is set and the sentence of the execution menu is read out from the memory by the display control means. At this time, the icon corresponding to the selected execution menu is also read from the memory and the sentence is written in the designated position. Therefore, when this sentence is displayed, the icon of the execution function is displayed in the sentence, so that it is possible to instantly determine whether the intended function is selected by the icon and operate the device without waste.

In addition, in the display selection device of the additional function of the present invention, when the operator performs an operation for selecting a function, the additional device detecting means 11 detects the presence or absence of the additional device that is the object of function selection. For example, when using the duplex function in the copier, if the operator operates the duplex switch, it detects whether there is an automatic document feeder or an intermediate tray for duplex copying. The message table of the selection menu is read out and the display data is set, with the optional function being available depending on whether or not the additional device is present. In accordance with the displayed menu, the operator operates an operation mechanism such as a switch or a key button, and the message table is read out sequentially, the display data is set, the function is selected, and the device is started using the selected function. Furthermore, since the message table has additional functions as options, the number of this message table corresponding to the number of options is reduced, the message tables can be aggregated, and the file size can be reduced and the processing can be simplified. In this case, the deletion of the choice is performed by the table setting means 12, and the message is displayed together with the choice of the function so that the function can be selected. The sentence to be displayed is composed of not only a string consisting of kana, kanji, and alphanumeric characters but also an icon (pictogram: image character) or an astarisk. In addition, in the call selection method using the function selection key of the present invention, when an operator selects a function, a predetermined group-divided group of functions is displayed on the screen of the display means together with the selection message as an option when the function selection key is operated. In other words, the operator may first select the function group by operating the function selection key. Therefore, the function selection key may be the number of days of the water with respect to the number of functions to be selected. It is also possible to change the sentence of the function selection displayed every time the operation is performed by one function selection key. In either case, when the sentence of function selection is displayed, the decision input of the selection by two key operations of the selection key and the setting key can be performed. Since the sentence is displayed by the sentence string and the icon, the operator is easy to see and understand the display contents.

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

In this embodiment, a description will be given of an execution function display method by an icon by using a copier as an example of a recording apparatus and having a switching and indicator for selection operation on the console panel of the copier. Prior to the description, the contents in the description of the present embodiment are shown.

(1) System configuration of the copier

2 shows the system configuration of the copier in one embodiment of the present invention.

As shown in the figure, the copying machine applied to the present invention can increase the function by attaching a desired additional device to the base machine 21 as the most basic configuration. Here, the base machine is a device having a single feed tray and a manual feed tray and capable of copying a manual set of originals on a platen glass. The base machine can be equipped with the following additional devices.

(1) IC card device 22;

The IC card device 22 is a device used to supply necessary data to the base machine 21 using the IC card or to write data from the base machine 21 to the IC card. When data (coordinate data) is input using the editor pad described later, the editor pad is connected to the IC card device 22 to perform the input operation. In addition, the IC card device 22 of the present embodiment is configured to alternatively control the IC card and the editor pad, and cannot input data using both.

In addition, the IC card used in the IC card device 22 of this embodiment has an ISO type interface and has a memory capacity of 2K bytes. By using an IC card, complex data can be stored on the card and fully coped with the automation and multifunction of the copier. For example, by providing an IC card for each industry or customer wall, even a copier having a complicated function can realize an operation method suitable for the owner thereof, and anyone can simply and inevitably operate the copier.

(2) ADF 23 and DADF 24;

The ADF 23 is commonly referred to as an automatic document transporting device, and is used to send originals one by one onto the tratened glass of the base machine 21 and discharge them after the end of the exposure. The exposure to the original is performed only on one side. On the other hand, DADF 24 is a document automatic transfer device for duplex, i.e., double-sided copy. In DADF 24, one side of an original is conveyed in the state which faces platen glass, and 1st exposure is performed. The front and back of the document after the end of exposure are returned to the DADF 24 tray. For this reason, when this 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 paper separately in a state where the additional device described later is used.

In the copying machine of the present embodiment, the ADF 23 or the DADF 24 can be used to automatically perform copying by various combinations such as double-sided documents, double-sided copies, and the like.

In addition, the ADF 23 is basically the same structure as the document automatic transfer device used in the copier, but in the case of the apparatus of the present embodiment, the insertion method of the document is set from the left side toward the machine and does not exit from the base machine 21. have.

(3) normal pratenses 25 and editorpad subpratenses 26;

The editor pad part Platen 26 has a structure in which a coordinate input device called an editor pad is placed on the platen for editing an original. The ordinary Fraten 25 does not have such a function.

(4) console panel;

The console panel has a backlit type 27 and a message display 28. Here, the backlit console panel 27 selectively illuminates a display panel on which a message fixed in a predetermined position is arranged in advance by a lamp or the like to read the portion.

The console panel 28 of the message display unit employed in the copier of the present embodiment is composed of a liquid crystal display device, 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 and operability of the copier system configuration.

(5) addition of feed trays;

This has the following representative forms: That is, in this embodiment, not only the addition of the terminal large capacity tray as proposed in Japanese Patent Application Laid-Open No. 57-77140 but also a combination of a supply tray more suited to the needs of the customer is realized. Such a combination of supply trays is also described in detail in "Multi-stage paper copying machine" of, for example, Real Element 61-081016, filed by the applicant.

(a) second and third supply trays 31-2 and 31-3; By adding these two supply trays, up to three types of copy paper can be sent out to the base machine 21.

(b) Second and third feed trays 31-2, 31-3 and intermediate tray 33, where intermediate tray 33 is used when making multiple copies on one side of the paper or alternately on two sides. The tray temporarily holds the finished paper.

(c) Second and third supply trays 31-2 and 31-3 and inter-bed trays 33 and fourth and fifth supply trays 31-4 and 31-5.

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

The high capacity tray is a high capacity tray that can accommodate thousands of copy papers.

(5) Receiving device of discharged copy paper

The copy paper is normally accommodated in the discharge tray 37, but the system is equipped with 10 bins and 38 bins. Therefore, copying can be sorted by up to 10 or 20 distribution lines by setting one of these sorters.

As described above, in this copier system, various additional devices can be selectively mounted on the base machine 21, so that a copier most suitable for the user can be provided. In addition, the copier can be increased in response to changes in the client's business style.

For example, it is often appropriate for customers who do not need to enlarge or reduce their manuscripts, or who have a small copy, to buy 21 base machines. For those who make a lot of copies or those who require complex copying, the intermediate tray 33 or a large capacity tray is often required. As a means for realizing such various requirements, one copier system has a structure in which each additional device can be easily attached or detached, and some of the additional devices include independent CPUs (central processing units) and a plurality of CPUs. Distributed control by means of This not only has the advantage that the customer's desired product is easily obtained, but the possibility of attaching new attachments also promotes the evolution of office work by teaching the customer the possibility of new copying. The purchase of the system is a big attraction.

(2) Configuration of software

(2-1) Advantages of Combination of Software

By the way, the system configuration of the copier described above can also be explained by the combination of the software of the copier of this embodiment. In other words, the copier can attach a variety of accessory devices, and correspondingly, the software can take a system configuration corresponding to each of these additional devices.

One of the reasons for adopting such a configuration is (i) If the base machine 21 includes operation control programs for all of these additional devices, the capacity of the memory required becomes large. In addition, (ii) it is possible to utilize these additional devices without instructing or expanding the ROM (lead only memory) in the base machine 21 when developing new additional devices or improving the current ones. .

As a result, the base machine 21 has a basic storage area for controlling the basic part of the copier and an additional storage area for storing a program inserted together with the functional information of the present invention from the IC card. In the additional storage area, various programs such as the control program of the ADF 23 and the control program of the control panel 28 of the DADF 24 are stored. When the IC card is set in the IC card device 22 with a predetermined additional device attached to the base machine 21, a program necessary for the copying operation is read out and loaded into the additional storage device. This loaded program acts like a program written in the basic storage area or controls the copy operation with a priority status to this program.

(2-2) Example of Differentiation

As such, the copier of this embodiment can influence the function of the program copier stored in the IC card. Therefore, by changing the program stored in the IC card in units of cards, it is possible to differentiate the use of the copier. Here are some easy-to-understand examples.

As a first example, a case will be described where a copier used by a plurality of companies is provided in a job building, or a copier used by a different company is installed in one company or a factory. The latter joint use is necessary for budget management, and in the past, the use management of each sector was performed using equipment such as a copyizer.

The copier has an IC card device 22, a DADF 24, a heater 38, a console panel 28, second to fifth feed trays 31-2 to 31-5 and an intermediate tray 33 on a base machine 21 shown in FIG. Let's call it a copier with a relatively high system configuration. Some co-users may need a DADF 24 or a sonar 38, while others may not need any additional equipment.

If several people or sectors with different usages try to determine the cost of the copier only by their copy amount, those who copy only the low copy object will oppose the introduction of the copier equipped with various attachments, so that they will use the copier highly. Or between divisions becomes difficult. In such a case, the IC card should be prepared according to the usage of each person or each part, so that a person or a part that desires a high level of functionality bears a lot of basic costs and makes use of many functions. For example, the owner of the most advanced IC card may operate the copier with the IC card set in the IC card device 22, thereby supplying the DADF 24, the sonar 38, and the second to fifth supply trays 31-2 to 31-5. And intermediate tray 33 can be used freely, and office efficiency can be improved. On the other hand, a person who does not need a sort of copy paper can reduce the cost by setting an IC card without a sorting program and using the topmost bin of the sorter as a discharge tray.

As a second example, a case where a carrier operates a self-copy service shop using an IC card will be described.

A plurality of copiers are arranged in the copy shop, and an IC card device is attached to each of them. The customer charges the IC card in response to the service aspect, sets it on the copier he wishes, and makes a copy by self-service. A customer unfamiliar with a copying machine can request an IC card equipped with a display function of an operation description as a program and set it so that various types of operation information can be displayed on the console panel 28 and copying can be executed in error. The use of DADF 24 or the execution of multicolor recording can be determined by the lending IC card, and the use model can be restricted, so that management can be made according to the fee. In addition, the status of the copying operation such as the number of copies and the size of the used copy paper can be entered, so that the billing can be easily made, and the sublime service such as a discount on the copying fee for regulars can be provided.

As a third example, a service using an IC card storing a program for a specific user will be described. For example, a patent office may need to make a copy at a relatively large magnification of 200% in the need to take the same copy as the original dimension when examining a patent publication that has been reduced by photo making. In addition, when drawing drawings to be submitted to the Office, the work of reducing or enlarging the original drawings at small intervals is performed in order to satisfy the request. In addition, in the area of copying of resident documents such as city hall or construction, the copy or copy shall be made by deleting the description information about the person who is the subject of the request or the privacy information of the place which should be kept secret in order to protect the privacy of the individual.

As such, there is a demand for a user to use the copier as a special mode of use. Setting the copier's function to meet all of these requirements complicates the console panel and increases the size of the ROM inside the copier. Thus, by arranging and setting the IC card for each specific user, a copier having a function most suitable for that user can be realized.

For example, in the example of the patent office, by purchasing a dedicated IC card, a 200% magnification ratio can be easily selected as a fixed magnification in addition to the usual several kinds of magnification ratios. In addition, it is possible to set the axial magnification at intervals of, for example, 1% within a range requiring fine adjustment. In addition, in the generation section of the resident documents, the type of resident documents and the fields or items to be deleted can be indicated on the display such as the LCD by operating the keys such as the ten key. Only the necessary sections, whether copied or not, will be edited and recorded.

(3) An example of the configuration of the device

3 is an external view showing an example of a system configuration of the copying machine of the embodiment described above.

In the copying machine of this embodiment, the DADF 24 is mounted on the base machine 21, and the IC card device 22 is disposed behind the upper surface. The console panel 28 of the message display unit is located directly in front of the base machine 21. In addition, although not shown in the figure, a tray 41 fitted by hand is attached to the right side of the apparatus, and a 10-well socket 38 is attached to the left side. The hand-inserted tray 41 is a tray for manual feed, but is capable of simultaneously feeding and sequentially feeding a plurality of sheets of paper.

The base machine 21 has already been described in which the first supply tray 31-1 is mounted as its basic configuration. In the copier of this embodiment, the second and third trays 31-2 and 31-3 are disposed below the fourth and fifth supply trays 31-4 and 31-5 with the intermediate tray 33 interposed therebetween. . All of these supply trays 31-1 to 31-4 and the intermediate tray 33 can be pulled out to the front, improving the operability and saving the space of the copier. In addition, a copier with a neat design that does not protrude from the ADF (Paper Document Transfer Device) or the paper feed tray is realized.

4 shows an outline of this copier. The photosensitive drum 51 is disposed in the base machine 21. The photosensitive drum 51 is uniformly charged by the charge corotron (charger) 52. The photosensitive drum 51 is configured to perform a constant speed rotation in the direction indicated by the arrow 53 in the drawing, and the charged drum surface is exposed at the exposure point 54. Here, an optical image of an unillustrated document placed on the platen glass 55 disposed on the upper surface of the base machine 21 is incident on the exposure location 54. For this reason, the exposure lamp 56 and the several mirror 57 and optical lens 58 which transmit the reflected light of the original surface illuminated by it are arrange | positioned, The predetermined | prescribed one among them is scanned for the reading of an original.

However, the electrostatic latent image corresponding to the original is formed on the photosensitive drum 51 by the image information exposed in the slit image at the exposure position 54. This electrostatic latent image is developed by the developing apparatus 59 to produce a toner image. The toner image moves with the rotation of the photosensitive drum 51 and passes near the transfer corotron 50.

On the other hand, the copy paper 60 accommodated in the first feed tray 31-1 disposed on the base machine 21 or the handwritten copy paper 60 connected to the hand-inserted tray 41 is sent out at a transmission rate of 61-1 or 63. And pass between the photosensitive drum 51 and the transfer corotrone 50 guided at a conveyance rate 69. At this time, the toner image is transferred onto the copy paper 58. The copy paper 60 after transfer transfers passionately between the hitrol 66 and the treasurer 67 between them. And it passes between conveyance rates 68 and 68, and is discharged on the discharge tray which is not shown in figure.

In the copying machine of this embodiment, the DADF 24 is attached to the base machine 21. Therefore, both sides of the original may be placed on the platen glass 55 one by one. In this case, first one side of the original laminated on the original receiving portion of the DADF 24 is set on the upper surface of the platen glass 55. At the end of copying, the document is set again in the original container in the front and back area and then sent again to the platen glass 55.

In the copying machine of this embodiment, five trays 31-2 to 31-5 and 33 are mounted under the base machine 21, but instead, the cabinet may be simply arranged and used for storing consumables. The base machine 21 can also be placed on a desk using the copier as a tabletop copier. Of course, it is also possible to mount only the second supply tray 31-2 under the first supply relay 31-1 and place the copier of this configuration on the desk as well.

5 shows an example of the console panel of the copier. Details of the display control technique described by the present applicant are disclosed in detail in "display apparatus" of real element 61-130320, "character display apparatus" of real element 61-066170, and the like. For example, the actual elements 61-130320 disclose that a copier is provided with a graphic display area by a dot pattern, and suggests that various displays can be performed using this graphic display area. For example, in a copier that can copy a document or move or delete an image, the image is read by the image sensor while the original is placed on a platen, and the outline is displayed in the graphic display area. It has been suggested to make it possible to prevent the occurrence of region setting or operation miss.

The console panel may adopt a plurality of forms, but as described above, the copier of the present embodiment uses the message display console panel 28.

However, the console panel 28 has a menu display panel 71 at the top thereof, and the contents of each panel portion 74 to 79 are displayed in text. Among them, one switch 81 and two display lamps 82 are arranged in the panel for 74, so that the sorting mode can be selected in the case where the socket is connected. In the sorting mode, there are a stacking mode for depositing copy papers in sequence and a matching mode for dividing copy papers by dividing the copy paper in each bin of the heater.

The following function selection panel 75 includes (i) a switch 83 for editing, correcting and checking an image, (ii) a switch 84 for storing in a narrow memory, (iii) a switch 85 for taking various other forms of copying, and (iv) Switches 86 for taking double-sided copies and indicator lamps 82 for indicating the selection of these switches are arranged. Here, (i) editing means a function for inputting data for editing using an editor, etc., and correction and confirmation means a function for displaying or confirming input data on a liquid crystal display which will be described later or exchanging data. . (Ii) The memory used here is a nonvolatile memory composed of random access memory backed up by a battery. Of course, other storage media such as an IC card, a magnetic card, and a PROFI disk can also be used as a non-volatile memory. In this copier, in order to reduce the burden on the operation of the console panel 28 by the operator, the setting of the image density, the magnification, and the like can be preset, and the preset value is stored in the nonvolatile memory. (iii) When switch 85 is pressed, text information is displayed on display panel 79 of console panel 28, and the desired function can be selected from the other functions.

The other functions of "here" include, for example, (a) page burst function (b) frameless function (c) iron margin function. Among these, (a) Page Continuous Function is a function to copy two pages of originals into two pages one by one and divide them into two pages one by one like a binding document. The (b) frame elimination function is a function of setting the frame around the picture information without copying the picture information of the peripheral part of the original. (C) The iron margin function is a function to set the “blank margin” at the right or left end of the copy. The iron margin can be set to the desired length and the value can be entered from the Tenkey 80 or the resin displayed at this point on the display panel 79.

(iv) At the end, double-sided copying is the function of copying on both sides of copy paper. In the case of double-sided copying, the copy woven fabric 60 in which the copy is made on the first side is first accommodated in the intermediate tray 33 shown in FIG. Next, copy paper 60 is again sent out from this intermediate tray 33, and copying is performed on the side which copying was not performed. In addition, the copying machine makes two copies on one surface in the case of monochrome color copying described below. In this case, studies have been made so that the front and back of the copy paper accommodated in the intermediate tray 33 are reversed from the case of the double-sided copy.

Four display lamps 87 showing the type (color) of the color developer are arranged on the top of the monochromatic color-enhanced panel 76 provided below the portion of the menu display plate 71 shown in Fig. 5 as " monochromatic color enhanced ". In this copier, the color developer can be set to one color or a plurality of colors among four colors, such as red and blue, so that the lamp corresponding to the currently set color is turned on.

In the remaining couple of monochromatic color-enhanced panels 76, display lamps 82 for displaying which of the four switches 88-91 and these switches 88-91 are set are arranged. Among these, (i) marking color switch 88 is a switch used when performing marking color. If the marking area is designated by pressing the switch 88, as an example, the color is overlaid on the part, and the recording is performed, so that the effect is as if the marking was performed.

(ii) The twisted color composite switch 90 is used for recording one color in a predetermined area of the copy. For example, if you place a figure to be expressed in color on the right side of platen glass 55 (see Fig. 4) and place an original on the left side, copy the original information of the manuscript into black and draw the figure in one color on it. do. At this time, if the designated figure is formed into a halftone dot, a color figure adjusted to a predetermined density by regeneration of the halftone dot is recorded in a predetermined area of the copy paper. In addition, there is a usage method in which the name or design of the product is placed on one side of the platen glass 55 and the paper on which the sales price of the product is written on the other side to simply display 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. (Iv) When the monochrome color switch 91 is selected, the original is copied in one color.

In the concentration panel 77 installed below the portion labeled “Copy density” on the menu display 71, an indicator lamp 82 indicating which of the five levels of copy density is selected and a shift key 94 for selecting one of these copy concentrations; 95 is arranged. When the upper shift key 94 is pressed, the density setting is performed in the direction of thinning the copy density, and when the lower shift key 95 is pressed, the setting is made in the direction where the copy concentration is transmitted. The copy concentration is determined 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 the amount of charge imparted by the charge corotron 52 to the photosensitive drum 51. It can be adjusted by changing. In this embodiment, for example, the development bias can be adjusted in 16 steps.

Under the copy density panel 77, an automatic density adjustment switch 97 is arranged. When the automatic concentration adjustment switch 97 is pressed, the automatic concentration indicator 98 is turned on to enter the automatic concentration adjustment mode. In this automatic concentration adjustment mode, a part of the light that is reflected from the source and reaches the photosensitive drum 51 when the document is being scanned is taken out by a half mirror or the like, and the potential of the developing electrode in the developing device 59 is set in response to the amount of light. .

The magnification and paper selection panel 78 provided on the lower side of the portion indicated on the menu display panel 71 has a portion for setting and displaying magnification on the left side and a portion for selecting paper on the right side. It is.

The magnification display section 99 is provided at the portion where the magnification is set and displayed. The copier can set magnification (linear magnification) at any 1% interval from 50% to 200%, and the set magnification is displayed on magnification display section 99. There are two types of display of the magnification, a method of setting an arbitrary magnification by the operation of the shift keys 101 and 102 and a method of selecting a predetermined fixed magnification.

When the arbitrary magnification is set, the shift keys 101 and 102 are operated. If the upper shift key 101 is pressed, the magnification is increased by 1% and the lower shift key is decreased by 1%. Holding down the shift keys 101 and 102 continuously changes the magnification by 1%.

The selection of the fixed magnification is made by pressing the fixed magnification key 103. The fixed magnification is indicated on the magnification display panel 104, and in this embodiment is 141.4%, 86.5%, 81.6%, and 70.7%. In addition, you can select 100%, which is equal. Which magnification is selected can be known by which of the display lamps 82 arranged adjacent to their left are lit.

In the portion where copy paper is selected, eight types of display panels 105 for displaying the paper size or paper type and shift keys 106 and 107 for selecting one of them are arranged. Immediately to the left of the eight kinds of display panels 105 is a display lamp 82 indicating which paper size or paper is selected. In this embodiment, the following display is performed on the display panel 105.

(A) hand-tipped tray markings; Select when using hand-mounted tray 41 (FIG. 4). Since this type of conventional hand-insertable tray is inserted by hand one by one, it is only necessary to first send out the copy paper from the hand-insertable tray at the time of hand insertion, and there is no need for the operator to select the hand-insertable tray itself. On the other hand, the hand-insertable tray 41 of this embodiment can set a plurality of copy sheets at the same time. Therefore, when feeding from the tray 41 to which the hand-held paper is inserted by setting the copy paper, there is a possibility that the feed can be started when a plurality of copy papers are set. In order to prevent such a situation, the tray 41 to be inserted by hand is selected.

(B) A3 paper marking; Select this when using the tray for sending A3 size copy paper in the long direction.

(C) B4 paper marking; Select when using the tray for sending B4 sized copy paper in the longitudinal direction.

(D) A4 paper marking; Select when using the tray to send A4-size copy paper in the long direction.

(E) B5 paper marking; Select to use the tray for sending B5 sized copy paper in the long direction.

(F) displaying A4 paper; Select when using the tray for sending A4 size copy paper in the direction perpendicular to the long side.

(G) B5 cross sheet marking; Select to use the tray for sending B5 sized copy paper in the direction perpendicular to the long side.

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

An automatic paper / magnification selection switch 109 is disposed below the magnification and paper selection panel 78. Pressing this switch 109 selects the automatic paper / magnification selection switch 109 and selects a combination of preset magnification and paper size. The operator can decide whether or not the desired combination is selected in the lighting state of the display lamp 82 in the magnification and paper selection panel 78. If it is not the desired combination, press the automatic paper / magnification selection switch 109 to change the combination.

The display panel 79 is arranged on the right side of the magnification and paper selection panel 78. On the display panel 79, a pattern 111 of this copier and a liquid crystal display 112 are arranged. In Fig. 111, the state of selection of the supply tray and the place where the paper is clogged are indicated by the lighting of the lamp. The sentence including Chinese characters may be displayed on the liquid crystal display 112 of this embodiment. The example shown in FIG. 5 shows that the copying operation can be started and that the set number of copies is one. The liquid crystal display 112 of this embodiment uses droplets for color display, and the designated areas are displayed in designated colors, respectively.

Keys or buttons are arranged below the display panel 79 as follows.

(A) Clare Button 114; It is a button for returning the copier to the default state, that is, the priority mode initially set such as the selection of copy paper 60 or the like.

(B) Tenkey 80; It is used for numerical input to set the number of copies or to specify the contents of the diagnosis at the time of diagnosis of a copying machine.

(C) emergency copyover 115; It is used when you need to make another emergency copy when you are making a continuous copy. It is also used for emergency copy release to return to the original copy operation when the emergency copy processing is finished.

(D) stop clear button 116; It acts as a clear button when the copy operation is set in the middle, when the number of copies is set, or when the bin of the heater is set.

(E) start butter 117; Key to start copying operation.

(F) selection key 118; The key to move the console to the displayed message, that is, the console key.

(G) setting key 119; The key (return key) for setting to the place designated by the console.

As described above, the console panel of this embodiment has a completely separated arrangement of areas of basic operation, for example, paper selection and copy density setting, and areas of application operation, for example, function selection and monochromatic color enhancement. . In addition, by displaying a sentence mixed with Chinese characters and Kana on the liquid crystal display unit 112 and assisting the application operation, the occurrence of an error in the panel operation is reduced as much as possible.

(4) Circuit configuration

6 shows an outline of the circuit configuration of this copying machine (FIG. 2).

As shown in the figure, a distributed CPU architecture using serial communication centering on the main CPU 121 is employed. This is because it enables optimum placement of the controller and provides optimum cost performance. In terms of product development of the copier, shortening or efficiency of software development by module design, simplification of wire harness, etc., low cost, and ease of trouble processing can be expected.

In addition, since the processing efficiency is increased by decentralizing the processing by a plurality of CPUs, for example, even if an inexpensive 8-bit CPU is used instead of an expensive 16-bit CPU, a complicated and high-speed processing is possible. .

Moreover, model development becomes easy by the dispersion | distribution of such a process. That is, even when developing a new input / output device or the like, the program on the main body side (main CPU side) may become unnecessary, and the change is minimal even when a change is necessary.

In addition, the printed circuit board on the main body side does not need to store unnecessary I / O ports or programs due to CPU dispersion. Therefore, the cost reduction of a printed circuit board can be attained and the freedom of arrangement space is improved.

The copier controls the base machine 21 by the main CPU 121 (central processing unit) 121 and the inter-image lamp CPU 122 in the base machine 21. Here, the inter-image lamp CPU 122 is a CPU that specializes in the control of the inter-image lamp.

The inter-image lamp is used for erasing a part of the electrostatic latent image before development by irradiating light to the photosensitive drum 51 after exposure. Conventionally, for example, when copying an original of a B5 plate equally, light is irradiated to an area other than the B5 plate on the photosensitive drum 51 to prevent unnecessary formation of the toner image. The copying machine of this embodiment has a function of editing an image and the like as described later. Therefore, the formation of the electrostatic latent image may be limited to, for example, a predetermined spherical area or polygonal area, and partial deletion or the like of the electrostatic latent image is required to perform such a process. An inter-image lamp is also used for this. As described above, in the copier of the present embodiment, since the inter-image lamp is used while being highly controlled as compared with the related art, an independent CPU other than the main CPU 121 is used for this purpose.

As a control method of a copier, Xerox Co., Ltd., which has introduced such a distributed processing system, is described in detail in the technical contents and related documents in applications such as "Machine control apparatus and control method" of Japanese Patent Application Laid-Open No. 59-78371.

However, the communication method employed in the present invention is equivalent to the 4,800-carrent loop method, rather than the "wireless method" for the purpose of the high speed processing employed in the above publication.

The present applicant discloses the details of the inter-image lamp CPU 122 in the " image copying device " of actual element 61-152591 and the " image erasing device of copying device " of special element 62-023392.

In addition to the copying machine of the present embodiment, the following CPU is prepared and connected to the communication lines 123 and 124. The main CPU 121 also plays a role in integrating these CPUs and the CPU 122 for inter-image lamps.

(A) CPU 125 for document delivery; The CPU 125 for document transfer is a CPU that controls the DADF 24 shown in FIG. When ADF 23 (FIG. 2) is used instead of the DADF 24, the CPU provided in the ADF 23 is connected to the communication lines 123 and 124.

(B) The CPU 126 for a soot is a CPU arranged in a soot 38 of 10 bins. A dedicated CPU is also arranged in the 20-numbered socket 39. The main CPU 21 knows which sorts of the heaters 38 and 39 are connected and controls the classification accordingly.

(C) a display CPU 27; The display CPU 127 is a CPU used to display various information in Chinese characters on the liquid crystal display 112 attached to the console panel 28 or to display an area for editing. In the case of the console panel 27 (Fig. 2) of the backlit type 27, since a complicated display control is not necessary, a dedicated CPU is not used. In addition, when the liquid crystal display 112 is not used, designation of a figure or the like for editing is performed using a ten key.

(D) CPU 128 for tray control; The tray control CPU 128 is a CPU for controlling the fourth and fifth supply trays 31-4, 31-5, the large capacity trays and the intermediate tray 33 among the trays added to the base machine 21. The CPU performs these controls in response to the connected trays arranged on the rear side of the tray cabinet accommodating each tray.

Among these trays, the intermediate tray 33 is provided with a copy paper conveying motor independently, and the copy paper accommodated in this tray requires complicated control in which 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) control of intermediate tray 33 alone.

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

(v) Independent control of the large capacity tray.

(E) CPU 129 for cards; The CPU 129 for the card reads or writes when the IC card 131 containing the copier's function information or additional control information is used or when the IC card 131 is used for specifying the coordinates of the original. That's the part. Note that although the card CPU 129 is not used in this embodiment, the editor pad 132 can be controlled. Editor pad 132 is used for coordinate input and will be described later in detail.

FIG. 7 shows the circuit configuration centering on the main CPU which plays a pivotal role in the copier of this embodiment.

Incidentally, controlling the copier by a control device such as a CPU or a so-called microcomputer is the Shikan company. IEEE `` A programmable Digital Control System for Copying Machines '' by SIKANDA SHEIKH, IEEE Trans, Com, Vol, IECI-21, No. 1, Feb, 1974 and Japanese Patent Application Laid-Open No. 50-62644 are known as a paper or a publication based on an electrophotographic copying apparatus and its apparatus.

It is not necessary to say that other CPU modules have a configuration such as a one-chip CPU, ROM RAM, I / O, etc., like the main CPU.

(A) The main CPU 121 is connected to the following parts through the serial communication lines 123 and 124 as described in FIG.

(i) DADF 24.

(ii) Sauter 38.

(iii) Liquid Crystal Display 112.

(iv) Interface for IC Card Editor Pad (I-E Interface) 130; This is an interface circuit arranged in the IC card device 22. When the IC card 131 or the editor pad 132 is connected to the copier main body, data is transferred from the main CPU 121 to these.

(v) Inter-Image Lamp Controllers 157.

(vi) Tray control section for controlling the fourth and fifth supply trays 31-4, 31-5, the intermediate tray 33, and the like.

(B) In addition, the main CPU 121 has an A / D converter and is connected to the following parts via analog data 134. Examples of such CPUs include 8-bit one-chip CPUs, such as Nippon Denki Co., Ltd., μPD 7810CW, μPD 7811CW, and Fujitsu Kabushiki Kaisha MB89713X.

(i) light quantity sensor 135; It is a sensor used when detecting the amount of light of the exposure lamp 56 (FIG. 4) and performing the control.

(ii) temperature sensor group 136; Sensors such as soft touch sensors for fixing temperature control described later.

(iii) paper side sensor group 137; It is a sensor for detecting the size of paper accommodated in the feed tray 31 and the like. According to the system configuration of the copying machine of this embodiment, copy paper 60 can be sent out from up to five types of trays.

Therefore, if four sensors are placed in one supply tray for detecting the paper size, and the digital data is used for the processing, four bits of digital data need to be sent from one tray to the main CPU 121. In addition to the need for an input port, the number of connectors and the number of cables constituting the harness increase. This is undesirable from the viewpoint of cost, miniaturization request, and reliability.

Thus, in the copying machine of the present embodiment, the state specified by the states of four sensors per one tray is sent out as analog data. The main CPU 121 converts the sent analog data into digital data and determines up to 16 types of copy paper 60 contained in each tray.

(C) The main CPU 121 is connected to the following parts via the bus line 121A in addition to being reset at the time of runaway or start by the reset circuit 138.

(i) Keyboard display LSI (large scale integrated circuit) 121B: A circuit for relaying data between the console panel 28 and the like.

(ii) Timer counter LS1121C: This circuit controls the driving of the main motor 164 and the carriage motor 171.

(iii) ROM 121D: Read-only memory having a capacity of 56K bytes and storing basic control information of the copier, functional information between copiers, and conversion tables.

(iv) RAM 121E: Random access memory for temporary storage of data having a capacity of 6K bytes. The above-mentioned nonvolatile memory (NVM) 12F is connected to the RAM 121E, so that the necessary data can be stored even when the copier is turned off.

Here, as necessary data stored in the nonvolatile memory (NVM) 121F, for example, (a) a setup value for adjusting the registration of copy paper 60, or (b) the tip of the image by the inter-image lamp described in detail later. (C) Fine adjustment values of vertical and horizontal magnification when copy ratio is set to equal magnification (d) Copy amount of copier similar to copy margin when copying with blank space for margin (E) Data for identifying the copier's usage status, such as adjustment of each parameter performed in the production line or (e) each tray 31's actual failure of the feed counter. In addition, depending on the device (f), the conversion table may be written into the nonvolatile memory for the functional information between the copiers. In this case, there is an advantage that the table for conversion can be rewritten by the enemy using external information such as an IC card.

(v) first I / O controller 121G; It is an input / output controller that inputs various data through the filter circuit 121N and drives various components through the driver circuit 1211.

Here, for example, various switches and sensors are connected to the filter circuit 121H. The driver circuit 1211 is connected to solenoids such as the debe solenoids described later, and the like, and the 233 described later in the supply trays 31-1 to 31-5.

(vi) second I / O controller 121J; It is an input / output controller that inputs various data through the filter circuit 121K and drives various components through the driver circuit 121L. Here, for example, various switches and sensors are connected to the filter circuit 121K.

The driver circuit 121L includes a well-known D / A (analog-to-digital) converter and a PWM (pulse width converter), and the debias setting of the developing device 59 and the charge co-tron 52, etc. described later in accordance with the processing of the program. The current value is set.

(5) Specific circuit configuration of copier

Next, the circuit configuration of the copying machine of this embodiment will be described in more detail with reference to Figs.

(5-1) periphery of photosensitive drum

8 shows the periphery of the photosensitive drum 51.

Charge corotron 52, inter-image lamp 141, four types of developing devices 59S 1 to 59S 4, main developing device 59M, transfer corotron 50, detaxorotron 147, Frecrine corotron 148, The cleaning device 149 and the erasure lamp 155 for antistatic are arranged in this order.

Here, the first sub-development apparatus 59S 1 is a developing apparatus for developing with red toner, and the second sub-developing apparatus 59S 2 is a developing apparatus for developing with blue toner.

The third sub-developing device 59S 3 is a developing device for developing with green toner, and the fourth sub-developing device 59S 4 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 disposed in front of these light emitting diodes in parallel. Plastic lenses (not shown) have spherical edges at positions corresponding to one light emitting diode, and light on the photosensitive drum 51 is not uniform in intensity at their boundary regions even when adjacent portions of the light emitting diodes emit light. It is considered not to be.

In addition, the focus of the plastic lens is moderately blurred on the strong light drum 51. Therefore, even in the case where, for example, the triangular shape processing (extraction or removal of the shape) is performed by the inter-image lamp 141, the level difference generated for each unit of diode at the boundary of the processing is considerably reduced.

The inter-image lamp controller 157 is configured to perform ON / OFF control of light emitting diodes separated by 123 segments of the inter-image lamp 141. The cleaning device 149 is provided with a doctor blade 150 and is adapted to scrape off the toner depleted with the Freklin Corotron 148 from the photosensitive drum 51.

However, in the copier of the present embodiment, the main motor 164 starts to be driven at a time exceeding 0.2 seconds after the sole blade 150 contacts the photosensitive drum 151. In addition, even when the main motor 164 is stopped, the dogblade 150 does not immediately fall from the photosensitive drum 51, but falls 5 seconds later.

This is a study to prevent a situation in which toner is scattered by vacuum suction operation and contaminates the inside of the copier.

The subdevelopers 59S 1 to 59S 4 are each provided with the following parts.

(A) color sensors; A sensor for judging which color developer is used in each of the sub-developers 59S 1 to 59S 4 is set. Even when the sub-developing device 59S is composed of combinations other than the above-mentioned red, blue, green, and brown, the color type can be detected for each of the sub-developing devices 59S 1 to 59S 4 by this sensor. The detection output is inputted to the debecala detection circuit 230 and transmitted to the main board 230.

(B) toner sensors; It is a sensor for determining the necessity of toner supply.

(C) dispense motors; A motor for stirring and replenishing toner in a toner box.

The main developing unit 59M is for developing by black sand and is provided with a toner sensor and a dispensing motor. Increment switch 159 is a switch which the operator presses to increase or decrease the amount of toner.

When the ink switch 159 is pressed while one of the subdevelopers 59S 1 to 59S 4 is selected, the toner is increased for the corresponding subdeveloper. When the main developing unit 59M is pressed, the black toner is increased.

Debe (shape) selection and solenoid 161 is a solenoid for alternatively switching five shaping devices in total, the main shape device 59M and the sub-development devices 59S 1 to 59S 4. This switching operation will be described later with the following terms changed.

The high voltage power supply (HVPS) 162 is used to improve the reproducibility of the solid part (the beta black part) of the original by making a parallel electric field inside the main and sub developing devices 59M, 59S 1 to 59S 4.

The flat toner sensor 163 is a sensor for detecting whether or not toner has been sufficiently collected in the toner recovery container. The main motor 164 is used for driving the conveying system from the registration timing of the photosensitive drum 51 and the heat 66 or the copying paper 60 to the discharge timing.

(5-2) Switching mechanism of developing device

9 is a waveform diagram showing switching timings of the main and sub-developing devices of this embodiment. The same figure shows an example in which the red color is developed in the first sub-developing device 59S 1 at the first time and the shape of the monochrome is performed in the main developing device at the second time.

When the start button 117 (FIG. 5) of the copier is pressed and the copying operation is started, the main motor 164 is driven from the time t ₁ as shown in FIG. The driving of the main motor 164 is continuously performed in the two developing apparatuses 59S 1 and 59M until the time t ₃ when the copying operation is completed.

Figure b shows the drive timing of the debe selective solenoid 161. The debe selection solenoid 161 is excited until the red copying operation by the first sub-developing device 59S 1 ends.

In this device, the lever hits the main surface of the clutch (not shown) by the excitation of Debe Selection Solenoid 161. The clutch receives the transmission of the driving force from the main motor 164 to start rotation of five sets of cams (not shown) with one protrusion staggered by 72 °.

When one of these protrusions comes in contact with the first sub-developing device 59S 1, the first sub-developing device 59S 1 is pushed by them in the direction of the photosensitive drum 51. At this time, the protruding portion of the remaining cam is located farthest from the main developing unit 59M or other sub-developing units 59S 2 to 59S 4, and in this state, the main developing unit 59M and the other sub-developing units 59S 2 to 59S 4 are separated from the photosensitive drum 51. In position.

Projections are arranged at five places on the main surface of the clutch, and the corresponding protrusion of one cam is most strongly pressed against the first sub-developing device 59S 1 when the lever hits the corresponding protrusion.

At this position, development is performed by the corresponding red color toner. In this case, however, the main developing device 59M is arranged to approach the photosensitive drum 51 in the initial state. Therefore, the phenomenon of the color of the red light does not start immediately from time t ₁ but the operation is waited for one second.

At this time, the cam is set in the photosensitive drum 51 with the first sub-developing device 59S 1 (or sub-developing devices 59S 2 to 59S 4) instead of the main developing device 59M.

When the copying operation by the first sub-developing device 59S 1 is completed, the five cams are moved for one _second from the time t ₂ , and when the projection of the cam for monochrome is positioned by the lever, the main developing device 59M Is set for. After that, development by monochrome is performed.

When the marking is performed in a red color, the marking is performed in a plurality of colors, but the corresponding ones of the sub-developing apparatuses 59S 1 to 59S 4 are sequentially selected in a predetermined order, and then they are monochrome. The phenomenon by is performed.

FIG. 10 shows the case where the development is first performed in monochrome and later in red. The same figure a shows the operation | movement of the main motor 164, and the same figure b shows the operation of the debe selection solenoid 161. FIG.

In the case of FIG. 10, since the phenomenon is first developed by the main developing device 59M, it is not necessary to take a waiting time of one second at this point. However, when the phenomenon of the second time is completed by the monochrome, it is necessary to take one second to set the main developing device 59M for the photosensitive drum 51 again.

(5-3) optical system

Next, the relationship between the optical systems will be described with reference to FIG.

A carriage (not shown) in which lenses, mirrors, and the like are disposed is reciprocated by the carriage motor 171. This carriage motor 171 is comprised by the step motor. Position control when the carriage returns to the home position is performed by the register sensor 172.

The resist sensor 172 is also used for timing the optical system and the conveyance of copy paper 60. That is, an actuator is disposed in the carriage to block the transmission of light. When the carriage is moved, the resist sensor 172 detects the temporary blocking of the light beam by the light shielding by the actuator.

Using this detection signal, the position or timing for registration registration is determined, or the position of the home position at the time of carriage return 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 performs the control of the copy concentration by simultaneously performing three adjustments of the amount of charge to the photosensitive drum 51, the exposure amount of the image, and the bias of the developing electrode.

The lens mirror sensor 174 is a sensor which performs movement control such as an optical sensor 58 and a mirror 57 (FIG. 4), but is composed of one detection element.

The lens mirror motor 175 has also been changed to a type capable of driving a common copier that has driven the lens 64 and the mirror 57 separately in a conventional copier. The exposure lamp 56 has been described above. The optical fan 177 is a fan for cooling the plate of the optical system to remove heat of the platen glass 55.

It can be connected.

As described above, the IC card apparatus 22 is controlled by the CPU 129 (sixth) for the card. The console control unit 191 is connected to the main board 201. The main CPU 121 is mounted on the main board 201.

(5-6) Billing Counter

Next, the billing counter used for increasing the copy fee will be described with reference to FIG.

Since the base machine 21 of the present embodiment can take five copies, two types of billing counters are provided. Of these, the main billing counter 211 counts the number of copies copied regardless of monochrome or color.

The counting value of the main billing counter 211 is used as data for counting control even when an accessory 212 such as a coin kit or a key counter is attached to the copier. Subbilling counter 213 is used to count the total coefficient of the number of colors used in each copy when a copy of the color is made.

(5-7) power

Next, let's talk about power supply with Figure 12. The base machine 21 is connected to a commercial power supply of 100V (volts). In addition, it is able to cope with power supply of 115V 60HZ and 220V 50HZ for overseas use.

The main switch 224 is reached via a 15 amp circuit breaker 222 and a noise filter 223 supplied from the outlet 221. The output side of the main switch 224 is supplied as a power source to the AC driver 226, the fixing control element 227 and the DC power supply 228 via the interlock switch 225.

(5-8) carrier

Next, with reference to FIG. 13, the conveyance system of copy paper will be described.

The first to fifth supply trays 31-1 to 31-5 are provided with a no paper sensor 231, a size sensor 232, and a clutch 233, respectively. Here, the no-paper sensor 231 is a sensor for detecting the presence 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 feed trays, and in this case, copy paper of the same size can be fed automatically from another supply tray when copy paper of one feed tray is gone. have.

The size sensor 232 is a sensor for determining the size of the copy paper accommodated in the tray. In addition, the clutch 233 is a component for turning ON / OFF control of each conveyance roll 61-1, 61-2, ...,.

The feeding of copy paper is performed by a feed motor 235 provided exclusively. The step motor is used for the feed motor 235. It is detected by the feed sensor 236 whether the feeding of the copy paper is normally performed.

The gate solenoid 237 is a solenoid for registration to align the tip of the copy paper once sent out. This gate solenoid 237 is different from the usual solenoid of this kind, and performs control to allow the gate to pass through the copy paper when energizing.

That is, in the standby state where the copy paper does not arrive, the gate solenoid 237 is not supplied with power and the gate is left open. In a slightly earlier advantage of the arrival of copy paper, the gate solenoid 237 is energized to close the gate to prevent passage.

At the time when the conveyance of the copy paper is resumed at a predetermined timing, the energization is stopped and the gate is opened. Such control reduces the variation in the gate position when the tip of the copy paper is prevented from passing, and the positioning can be performed accurately even when the copy paper is pushed by the gate with a relatively strong force.

The hand-insertable tray switching solenoid 238 is a solenoid for switching the conveying roller of the copy paper sent out from the first feed tray 31-1 and the conveying roller of the copy paper fed manually from the hand-inserted tray 41 and the drive.

The hand-inserted tray sensor 239 is a sensor for detecting the presence or absence of copy paper when sending a plurality of copies from the hand-inserted tray 41. The tray interlock 241 is an interlock switch attached to a mechanism in which copy paper is opened and closed for removal when a paper jam occurs.

The tray path sensor 242 detects copy paper 60 sent from the second and third supply trays 31-2 and 31-3, and is disposed in the vicinity of the coupling portion of the base machine 21 and these supply trays 31-2 and 31-3. have.

(5-9) DADF

The DADF 24 will be described in detail with reference to the fourteenth.

DADF 24 is mounted on platen glass 55 of base machine 21. The DADF 24 is equipped with a document tray 252 for placing an original 251. In the document tray 252, an original 251 is laminated so as to be below the first surface to be copied.

A retard pad 254 and a discharging pad 255 are arranged on the document dispensing side of the document tray 252, whereby one document 251 is sent out one by one. The circularity 251 sent out is pushed by the driving roller 256 and the driven roller 257 through the S-shaped conveying section 258 and the branch guide 261 disposed at the position where the S-shaped conveying section 258 and the vertical conveying section 259 intersect. The branch guide 261 is thereby opened, and the original 251 is returned to the inverted broadcast section 262 side.

When the rear end of the manuscript 251 passes through the branch guide 261, the branch guide 261 is closed to the S-shaped conveyance section 258 by the action of a spring (not shown). At this time, passage of the document 251 is detected by a sensor (not shown) arranged near the branch guide 261.

By this detection signal output, the driving roller 264 for the document transfer is reversed. As a result, the document 251 is inverted in the conveying direction and the conveying direction is changed in a direction substantially perpendicular to the platen glass 55.

The circular arc 251 is then conveyed while being positioned by contacting the side positioning guide (not shown) by the inclined row slip paddle 265. And it is conveyed to the appropriate position of 55th platen glass by the endless conveyance belt 266. In this manner, copying of the first surface of the original 251 is performed.

When the exposure to the first surface is completed, the document 251 is conveyed in the direction of the arrow 267 by the endless conveying belt 266. When the copy of only the first surface is performed by the action of the exit guide 268, the vertical conveying section 269 is selected and the document 251 is received by the document receiving section 271.

On the other hand, when copying also to the 2nd surface opposite to a 1st surface, the horizontal conveyance part 272 is selected. The document 251 sent to the horizontal conveying section 272 is conveyed in the reverse direction to the arrow 267 by the conveying roller 273 and conveyed to the S-shaped conveying section 258 by the driving roller 256 and the driven roller 257.

At this time, the lower surface of the manuscript 251 is the second side of the time point and the station which was accommodated in the document tray 252. Therefore, copying of the second surface is performed in the state where the manuscript 251 is sent on the platen glass 55 in the same transfer procedure as described above.

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

(5-10) Sotho

The first tuplex pass sensor 352 is placed on the base machine 21 side, and the second duplex pass sensor 353 is arranged in the vicinity of the second feed tray 31-2, and is copied before reaching the vicinity of the intermediate tray 33. Paper jam is detected for the paper 60.

However, there is no transfer roll in the intermediate tray 33 for sending the leading edge of the copy paper 60 to the leading edge of the tray. Thus, according to the size of the copy paper 60 sent, three tuplex solenoid gages 355 to 357 are arranged for transporting them to a desired position and dropping them into a tray.

These duplex solenoid gates 335 to 357 are to operate the solenoid alternatively according to the size of the paper to be sent to open and close the corresponding gate. The skewol solenoid gate 358 controls the corner of the tip of the fallen copy paper 60 to fit into the corner of the tip of the center tray 33, and the gate of the single piece of copy paper 60 sent in parallel. When this operation is finished for one minute, the counting of the main billing counter 211 is performed.

As described above, the intermediate tray 33 is controlled by the CPU 128 for tray control and conveys the copy paper under the control of the Duttlex motor 361 (Fig. 8).

The duplex-no-paper sensor 362 is a sensor for detecting copy paper 60 in this intermediate tray 33. The duplex feed clutch 363 is a mechanism for performing ON / OFF control with respect to a drive source for feeding out copy paper 60.

The inverter gate solenoid 364 is a solenoid that switches between double-sided copying or marking with a plurality of colors on the same surface or synthetic copying.

That is, as shown in FIG. 16, when the inverter gate solenoid 364 is located in the direction, the copy paper 60, which has been conveyed to fall downward on the conveying path 365, is guided to the inverter / gateton solenoid 364, and is transported to the transfer roll 367, This time it is returned upward by 368.

Immediately in front of the inverter gate solenoid 364, the conveying direction is changed in the right direction in the drawing, and the intermediate tray 33 is accommodated in the front and rear station. When the conveyance is resumed in this state, a double-sided copy is made.

On the other hand, if the conveyance direction of the copy paper 60 conveyed downward is changed to the right direction of the drawing as it is in front of the inverter gate solenoid 364, the original surface side is accommodated again. When conveyance is resumed in this latter state, copying is made on the same surface again.

In general, in the case of marking with N kinds of colors, one copy paper 60 is accommodated in the intermediate tray 33 N times, after which development is carried out in monochrome and discharged.

The duplex feed sensor 369 is a sensor for detecting the presence or absence of paper clogging of the copy paper sent out from the intermediate tray 33.

(5-13) large capacity tray

By the way, this copier can set the large capacity tray 471 instead of the 4th and 5th supply trays 31-4 and 31-5. By the way, although it is different from the structure of a present Example, it demonstrates briefly.

20 shows an outline of the circuit configuration of the large capacity tray.

The large-capacity tray 471 can set 1000 to 2000 sheets of copy paper at a time, and can make a large amount of copies without interruption. The large capacity tray 471 is equipped with the following circuit components. In addition, the large capacity tray 471 receives an AC power supply from the output side of the noise filter 233 shown in FIG. 8, and similarly receives a DC power supply from the DC power supply 228 via the main substrate 201 shown in FIG.

(6) function selection and display

(6-1) Additional devices and additional functions

As described with reference to Fig. 5, the function selection panel 75 is provided with switches 83 to 86 and display lamps 82 for indicating whether or not these switches are selected to select various functions. ) Belong to a plurality of functions, and the functions selectable by the operation differ depending on what is attached as an additional device.

The copying machine according to the present invention can be equipped with a DADF 24, an intermediate tray 33, an IC card device 22 and the like, but these are optionally installed as an additional device according to the user's request. Therefore, when these additional devices are attached, new functions that could not be used in the base machine can be used and the combination of the available functions is also changed.

For example, when the DADF 24 is mounted, the exposure can be continuously performed on both sides of the document. The first exposure is carried out by conveying one side of the original in a state that can face the platen glass, and after the exposure is completed, the front and back are reversed, and the original is returned to the tray of the DADF 24.

By again sending the original, the exposure surface and the reverse surface can be exposed.

When the intermediate tray 33 is mounted, the copied copy paper can be accommodated here, and the front and back sides of the copy paper can be accommodated reversely as well as the previous surface side can be accommodated again. .

Therefore, the DADF 24 and the intermediate tray 33 have different functions that can be used when one is equipped and both are equipped. For example, in the case of double-sided function, the function of double-sided original → single-sided copy is used only for DADF 24 only, and the one-sided original → double-sided copy only for middle tray only. Three functions can be used by adding two-sided originals → one sided copy, and two-sided originals → two-sided copy. When selecting these functions, the double-sided switch 86 is operated.

In terms of editing function, if there is neither DADF 24 nor intermediate tray 33, editing and sheet synthesizing cannot be performed, but if intermediate tray 33 is used, sheet synthesis is possible, and if DADF 24 is added, parallel synthesis is also possible. Become.

To select these functions, edit switch 86 is operated. In this way, the combination of additional functions that can be used even in the case of the DADF 24 and the intermediate tray 33 as additional devices is varied.

In the editing function, the sheet composition is a function of recording the entirety of both the first document and the second document overlaid on one copy sheet. In the copying machine of this embodiment, the first original can be designated up to five areas, and the first original and the second original can be copied in different colors by using different monochromatic color switches 91 (FIG. 5).

On the other hand, parallel synthesis is a function of creating a synthetic copy on one copy paper by attaching the entire second document to the entire first document. Originals are sent from ADF 23 or DADF 24. Therefore, copiers not equipped with them cannot use this parallel synthesis function.

In addition, the copier according to the present invention has a nonvolatile memory composed of a random access memory backed up by a battery as described above, and presets copy conditions such as image density and magnification so that the nonvolatile memory can be stored in the nonvolatile memory. It is supposed to be.

In the case of calling or registering the preset memory contents, the narrow memory switch 84 is operated, but there is an IC card corresponding to this nonvolatile memory, and there is an IC card device 22 as an additional device. The IC card device 22 writes the data of the structured copy service on the IC card and supplies the data of the structured copy service from the IC card to the base machine, for example, to automate complex copying tasks for each industry or user, It is to make sure that operation can be performed.

Therefore, on the IC card, certain information that can operate the copy paper in a predetermined form, such as the number of copies, page continuous, magnification ratio, margins, left-line, right-sided, copy density, and optional information on both sides of the page, etc. Can be written from the IC card apparatus 22.

Therefore, when the user carries the IC card and makes a standard copy, the IC card device 22 reads the information of the IC card to automatically execute the standard copy work without performing complicated operations on the console panel. Even when such an IC card device 22 is equipped, the contents that can be used for the narrow memory function vary.

As described above, if various additional devices can be attached to the base machine and the additional functions available by the combination are also different, the user can not easily distinguish between the functions that can be used and the functions that cannot be used.

Therefore, in order to eliminate such confusion, it is not necessary to display the functions that are not available and to be able to easily select and use the desired functions by simply selecting the desired functions within the range of available additional functions without being aware of the presence or absence of additional devices. A good device can be provided.

As the display means, the liquid crystal display can display character strings and icons (pictograms, image collectors), so that the display can be easily identified by the operator with little information based on the picture information by using the icons for function display.

(6-2) Configuration of function selection system

21 is a diagram showing a configuration example of a function selection system using a liquid crystal display capable of displaying messages.

22 is a diagram showing an example of the configuration of a display controller.

In FIG. 21, the main controller 501 is composed of the main CPU 121, the ROM 121D, the RAM 121, the I / O controller 121J, 121G, and the like described previously in FIG. 7, and has a determination function (program) of the presence or absence of an additional device.

The presence / absence judgment function determines whether the DADF 24, the intermediate tray 33, or the IC card device 22 described above is equipped. For example, when the connector is connected in the connector connecting the accessory and the main body, A signal line is provided, and this signal enters the main controller 501 via the filter circuit 121N shown in FIG. 7 and is judged by a determination program stored in the ROM 121D.

The means for determining whether such an additional device is present is not a signal based on whether the same connector is coupled or not. For example, a contact signal of a switch, a contact signal of a proximity switch, and an additional device that are pressed and turned on when the additional device is equipped, are used. Of course, it is also possible to use a signal from an optical sensor or other signal which causes the light from the light emitting unit to be detected at the light receiving unit when equipped.

In the main controller 501, the presence or absence of additional devices such as the DADF 24, the intermediate tray 33, and the IC card device 22 is determined in this manner. In addition, the main controller 501 has a message transmission table for displaying a guide for each function selection or copy condition setting in response to an operation of a function selection switch or a key, and a function selection switch (two-sided switch 86, edit switch 83, narrow) of the console panel 28. When the memory switch 84 and the other switch 85 are operated, the message transmission table is determined in accordance with the presence or absence of an additional device, and the designated information such as the presence or absence of function information, the size of the margin margin, the number of copies, and the like are set. The data is sent to the display controller 502.

The display controller 502 is a display CPU 127, ROM 503, RAM 504, serial interface 505, as shown in FIG. 22, and includes a sentence, character, or icon corresponding to each message transmission table that processes data in the message transmission table. It is stored in the font roll ROM 503.

According to the data in the message transmission table received from the main controller 501, the sentence is read from the ROM 503, the designated information is set in the sentence, the characters or icons constituting the sentence are expanded in the font, and the LCD driver 506 is controlled. Display a message message.

A specific example of the sentence will be described later. For example, when selecting a function, the message text "What do you choose?" Is followed by the icon of the key (selection key or setting key) to be operated and the function to be selected. It is an icon, a string (option), and an icon of the console.

In the 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 console position of the message transmission table.

Thereby, the display position of the console is shifted to the next position of the function to be selected, and when the setting key 119 is operated, the main CPU 121 recognizes this and selects the function corresponding to the console position of the message transmission table and selects the selected function. Determine the new message send table corresponding to.

In this way, when the copying becomes possible, the message transmission table of the sentence which has the message string "it can be copied" is determined. If the number of sheets to be set is set here, and the start button 117 is operated, the copy operation starts with the selected function and the desired copy condition.

(6-3) communication protocol

23 is a diagram showing a timing chart of serial communication, and FIG. 24 is a diagram showing an example of the configuration of serial communication data.

The communication between the main CPU 121 of the main controller 501 and the display CPU 127 of the display controller 502 is connected by the communication lines 123 and 124 as previously described in FIG. 6 and does not perform serial communication through the communication lines 123 and 124. However, the timing is transmitted and received in the order shown in FIG. 23 at a cycle of 100 m sec.

For example, 4 bytes are sent to the CPU 126 for the software, 5 bytes are sent to the CPIU 125 for the document transfer, and 9 bytes are sent to the CPU 127 for the display from the main CPU 121. Among them, the data transmitted from the main CPU 121 to the display CPU 127 is a control word (X'49 ') in byte 1, a 3-bit state and a 3-bit substate in byte 2, and byte 3 as shown in FIG. The 7-bit case number, bytes 4 to 8 are assigned 7-bit free data area, and byte 9 is assigned a check code.

The poly data area of bytes 4-8 is used to receive the data required by each sentence. For example, the bits of 1ST # DGT and 2ND # DGT shown in FIG. 24B are the transmit bits of the number corresponding to ^** mm, and the bits of the 3RD # DGT and 4TH # DGT as ^** transmission bits corresponding to ^** copy. ◇ 1 for mm, ◇ 2 for left and right of blank space function, ◇ 3 for page speaker, ◇ 4 for framelessness, ◇ 5 for ◇ 5 Color (0, black, 1, red, 2, blue, 3, green, 4, 5, 5), ◇ 7 with parallel synthesis, ◇ 8 with double-sided function (one-sided → It allocates as information bits of double-sided "1", double-sided → double-sided "2", and double-sided → single-sided "3".

(6-4) Structure of message sending table and sending data

25 is a diagram showing an example of the structure of a message transmission table. The serial transmission data shown in FIG. 24 is serial data generated according to the message transmission table shown in FIG. 25 and is managed by the main controller 501. FIG. And "STATE", "SUBSTATE", and "CASENO".

The content of "SENTENCE" is actually the content displayed on the liquid crystal display 112.

The main controller 501 selects one of the message transmission tables by operating various switches on the console panel 28. For example, the message transmission table shown in FIG. 25A is selected when the narrow memory switch 84 is operated. The contents of the transmission data details are then transmitted to the displayed controller 502 through the communication line.

In addition, the message transmission table shown in FIG. 11 (b) is selected when the edit switch 83 is operated. In this way, when the message transmission table is selected in the main controller 501 by the operation of the function switch, and the data of the message is transmitted to the display controller 502, the sentence corresponding to the display controller 502 is read out, expanded into a font, and displayed on the LCD 112. do.

The function is selected according to the displayed sentence (message), but in the process of selection, when the selection key is operated, the contents of this console are shifted one by one in the message transmission table. When the setting key is operated, the function of the console position is selected, and the message transmission table as shown in FIG. 25C is selected as the next step, for example.

This message transmission table displays the sentence "Can be copied" and displays an icon indicating that the function of erasing, single-sided and double-sided is selected by right side, and input the size and number of copies in the margin It is.

When these contents are transmitted as serial data to the controller 502 displayed from the main controller 501, a special code (OG) or asterisk (*) is placed at the position of the information icon specified in the data area such as a function icon or a numerical value in the contents of the "SENTENCE". ) Is read out, and the special code or the asterisk is rewritten to display the information designated in the data area and displayed on the liquid crystal display 112.

In order to perform such a process, the display controller 502 stores the text data and font data by the display control program and code in the ROM 503, as shown in 22, and moves from the received data long in the receive buffer area of the RAM 504 to the work area. The sentence data is read out, the icons, the numerical values, and the like are filled in, and each sentence data is expanded in a font.

(6-5) Icon and Font Data

Fig. 26 is a diagram showing an example of icons used in the present invention. These icons are represented by 16 × 16 dots, for example, (a) is an icon representing an extraction function, (b) is an icon representing a deletion function, (c) is an icon representing a partial color function, and (d) is (H) is an icon representing a memory, (i) is an icon representing a memory reading function, (j) is an icon representing a memory registration function, and (k) is a margin margin (left). Indicated icon, (l), is used as an icon representing iron margin (right).

As described above, when displaying a message, an option, and a selected function on the liquid crystal display 112 as a sentence, such an icon is used in a sentence. Information or confirmation information can be transmitted to the operator.

FIG. 27A shows a font of a sheet composite icon, and FIG. 2B shows an example of the font data. FIG. 2C shows a font of the Chinese character "縮", and FIG. This font is 16x16 dots, and the font data is expressed in hexadecimal by dividing one line of 16 dots into 8 dots which are half of them.

(6-6) Processing Block Configuration of Main Controller and Display Controller

28 is a diagram showing an example of the configuration of the functional blocks in the main controller 501 for display selection of additional functions, and FIG. 29 is a diagram showing an example of the configuration of the functional blocks in the display controller 502. FIG.

In FIG. 28 showing the functional configuration of the main controller 501, the additional device recognizing unit 511 recognizes the presence or absence of an additional device and the operation signal of the function selection switch, and the function selecting unit 513 is the signal of the additional device recognizing unit 511 and the console panel. This function selects the function in response to the operation of the selection key 118 and the setting key 119 provided with the.

The sentence number determination unit 512 has a message transmission table managed by the sentence number, and determines the sentence number indicated on the liquid crystal display 112 by the signal of the additional device recognizing unit 511 and the signal of the function selection unit 513.

The message transmission table is provided with hundreds of dozens of texts as shown in Figs. 25 or 27 corresponding to the display mode for function selection or the display mode when performing other functions of copying.

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 sentence (a) shown in FIG. 26 is a sentence determined when the narrow memory switch 84 is operated, and the sentence shown in FIG. 11 (b) is a sentence determined when the editing switch 83 is operated.

The function information set unit 514 sets function information on the sentence determined by the sentence number determination unit 512. For example, if the sentence number shown in Fig. 28A is determined by the operation of the narrow memory switch 84, the presence or absence of the IC card device 22 is checked. If the IC card device 22 is not mounted, the " 1 " Fill in the flag.

Likewise, if the sentence number shown in Fig. 22B is determined by the operation of the edit switch 83, the presence or absence of the intermediate tray 33 and the DADF 24 is checked. Stand up.

In the transmission buffer 515, a message transmission table of sentence numbers determined by the sentence number determination unit 512 is set. The function information unit therein is set by the function information set unit 514 and transmitted to the display controller 502.

In FIG. 29 showing the configuration of the display controller 502, the reception buffer 516 sets the data of the message transmission table received from the main controller 501. The sentence data file 517 stores sentence data (strings and icons) displayed on the liquid crystal display 112.

The font file 519 stores fonts of characters and icons constituting sentence data. The display control unit 518 processes the data of the message transmission table set in the water buffer 516 and expands the display font in the display buffer 520.

Reads predetermined sentence data from sentence data file 517 based on the received data "CONTROL WORD", "STATE", "SUBSTATE", and "CASENO", and fills the specified information in the sentence, and displays the font in the display buffer 520. Deploy.

Depending on the sentence data, it is necessary to perform rewriting of contents or the like with the information set at that time. For example, the function display, the margins, the number of copies, the number of cars, and so on are used. However, in each sentence data, a special code or an atrisk is set at the writing position in advance.

Therefore, when a sentence is read from the sentence data file 517, the display control unit 518 first blanks a special code or an atrisk, stores the position, and writes an icon or a numerical value at that position in accordance with the designated information of the receiving buffer 516. Is performed.

In the liquid crystal display 112, the writing process of the character example or icon is performed and the contents of the display buffer 520 in which the font is expanded are displayed.

(6-7) Selection display processing

Next, the function selection performed when each function selection switch is operated and the display processing therefor will be described.

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

When the double-sided switch 86 on the console panel is operated, check whether the DADF 24 and the intermediate tray 33 are installed.

④ In the case of DADF 24 degrees and intermediate tray 33 degrees, you can select from three functions: plate original → double-sided copy, double-sided original → double-sided copy, double-sided original → single-sided copy. And an icon indicating that the setting key is the next operation key, a choice of the three functions to be selected, and a message transmission table of a sentence indicating the selection position of the function are determined, and the sentence is displayed on the liquid crystal display unit 112.

Therefore, when this is displayed, the selector 118 moves the console to the desired function position and the selector 119 selects the function. Normally, if a function is selected here, the following message is displayed and the operation moves to the copy operation by the selected function.

⑤, ⑥ However, if there is DADF 24 but no intermediate tray 33, it is determined by the function of double-sided original → one-sided copy.If there is no DADF 24 but there is intermediate tray 33, it is determined by one function of plate original → double-sided copy. As a result, the message transmission table for the sentence that is to be copied and the content to set the number of copies is determined, and the sentence is displayed on the liquid crystal display unit 112.

Therefore, in this case, when the original is set, the copy mass is input at the Tenkey 80, and the start button 117 is operated, the copying operation corresponding to the function is started. When the double-sided switch 86 is operated as described above, the message transmission table of the sentence shown in (4) or the message transmission table of the sentence shown in (5) and (⑥) is used.

Fig. 31 is a diagram for explaining the flow of processing when the editing switch is operated.

When the edit switch 83 on the console panel is operated, check whether the ADF 23 or DADF 24 is present, and whether the intermediate tray 33 is present. ④ If there are any of ADF 23 or DADF 24 and intermediate tray 33, four functions of extraction, deletion, sheet synthesis, and parallel synthesis can be used, so the message string, selection key and setting key of "Which would you choose?" The message transmission table of the sentence which becomes the icon which shows that is a next operation key, the choice of the four functions to be selected, and the selection position of a function is determined, and the sentence is displayed on the liquid crystal display part 112. FIG.

(5), (6) However, if there is no intermediate tray 33, the sheet composition and parallel composition cannot be used together, so that the message transmission table of the sentence as in (4) is determined, and then the function information for deleting the option of this function is set. Therefore, the sentence with extraction and deletion as an option is displayed.

(7) Similarly, if there is an intermediate tray 33 but no ADF 23 or DADF, the parallel composition function cannot be used. Therefore, the function information to delete the option of this function is set, and the sentence with extraction, deletion and sheet composition as an option is displayed.

When the edit switch 83 is operated in this way, the set of the function information for the four options is only wrong. Therefore, the message transmission table of the same sentence is determined, and the desired function is selected using the selection key and the setting key after this message display. By doing so, it proceeds to the next step.

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

When the narrow memory switch 84 on the console panel is operated,

(1) First, check whether there is an IC card device 22.

(2) In the case of "YES", that is, if there is an IC card device 22, the card registration function can be used. Therefore, the "What will you choose?" And a transmission table for a sentence consisting of three options of "registration" and "card registration" and a selection position of a function are determined, and the sentence is displayed on the liquid crystal display unit 112.

(3) However, in the case of " ON ", that is, when the IC card apparatus 22 is not mounted, the message transmission table of the sentence as in the above (2) is determined, and then the function information for deleting the option of this function "card registration" is set. Thus, a sentence is displayed with the choice of calling and registering.

⑩, 감시 Monitors whether setting key 119 has been operated and, if so, sets the function of the option of the cab position to the machine.

⑫ At the same time, set the message transmission table of message No of "can be copied" in the transmission buffer.

(1) Information indicating the set function is set in the transmission table.

After that, every 100 m sec, the data of the transmission table is sent to the display controller 502.

In response to the processing by the main controller 501, the display controller 502 performs the following processing (see FIGS. 34 and 25).

①, ② First, obtain the head address of the sentence that waits for the end of the serial data to be displayed and copy it to RAM.

(3) The positions of the special code (G) and the atrisk (*) are stored next.

④ And delete all special codes.

5) Write data to the Asterista (*) position of 3RD # DGT and 4TH # DGT. If this data is 10, 10 copies are made and the number of copies is 10 copies.

(6) Check whether ◇ 1 is "0".

(7) In the case of YES, that is, if there is no margin margin function, four characters are deleted from the first astarisk.

⑧ Next, find the bit with "0" in ◇ 2 to ◇ 8.

9) Write the icons in order from the 1st position of the special code corresponding to the bits other than "0". In the example of illustration, ◇ 8 represents "3", that is, the case of both sides → one side.

메세지 Then a message sentence consisting of an icon and a character string is displayed on the liquid crystal display 112.

(3) Write data at the position of the astarisk (*) of 1ST # DGT and 2ND # DGT in the case of ＂Nomm (with mm indication), that is, when there is no iron margin function. Hereinafter, the same process as the above (8) is performed.

(6-9) Example of Message Sentences Displayed on the Liquid Crystal Display 112

35 shows an example of correspondence between the message number, the case number, and the message sentence.

As shown in Fig. 35, the message sentence stored in ROM 503 of the controller 502 for display is a character string used by a Chinese character, an alphanumeric character, etc., an icon used for displaying a function, or a special code (OG) digit of an icon writing position. As Atari risk (*) of the message No. The case number is read by addressing.

That is, when "Page Continuous Shutter" or "Frame Erase" is selected, an icon indicating the function is written under the "Can be copied" string, and the copy function is entered immediately after entering the number of copies.

On the other hand, when " iron margin " is selected, as shown in Fig. 39C, first, a selection mode of " left and right " or " right iron "

40 shows an example of a sentence in the operation of the switch of the monochrome color emphasis panel. When the marking color switch 88, the partial color conversion switch 89, and the continuous color combining switch 90 are operated, as shown in Figs. 40A to B, the sentence of the coordinate input mode having the letter example of " area " When the coordinates are input, the text "You can copy", the icon of the selected function, and the number of copies are displayed.

In addition, this invention is not limited to the said Example, A various deformation | transformation is possible. For example, in the above embodiment, a liquid crystal display is used to display an option of a function by a character string or an icon together with a message character string, but a CRT or other indicator may be used.

Also, the representation of font data may not be hexadecimal. In addition, although described by applying to a copying machine, it is a matter of course that the present invention can also be applied to other devices that allow various attachments to be arbitrarily mounted according to a user's request.

As is apparent from the above description, according to the present invention, when a function is selected and controlled in a recording apparatus such as a multifunctional copying machine, the message and the icon (pictogram) are not only a message by a string of kana and kanji characters. By using this function, the selection of the function to be selected or the selected function is displayed, thereby making it possible to display a message that is easy to see and easy to discriminate with concise and small red information and improves operability.

Furthermore, by selecting and displaying an option on the display screen by one operation, the function selection mechanism on the console panel can be reduced and the console panel can be refreshed. In addition, functions that cannot be used are not displayed as options and unnecessary information is not displayed, and thus there is no misunderstanding or confusion of the operator.

In addition, since the necessary information is displayed by the character string and the icon, and the function is selected, it is easy to understand and the operation error can be eliminated. By using an icon as a display character in this way, it is easier to recognize the moment than a character string. When the display contents are flickered, it is possible to quickly determine what should be observed from the whole, and to perform a function selection operation quickly.
