Description

Detailed Description of the Invention "Field of Industrial Application" The present invention relates to a recording device for recording image information such as a copying machine, facsimile machine, printer, etc. Regarding recording devices that can be used.

"Prior Art" Taking a copying machine as an example, in recent years, products with advanced functions have been actively developed. For example, regarding the copying magnification of originals, in addition to copiers that only make copies at the same size, there are also copiers that allow you to select from several different magnifications, and even copiers that can change the magnification continuously. Regarding development, in addition to copying machines that use one type of toner to reproduce images in so-called black and white, there are also copying machines that use two or more types of toner to perform multicolor recording or select a color to record. A machine is appearing. Looking at the handling of manuscripts, we have seen the emergence of copying machines equipped with devices that automatically replace manuscripts, and copying machines that copy two-page spreads of bound manuscripts one page at a time without moving the manuscript itself. It is appearing.

``Problems to be Solved by the Invention'' Copying machines with more advanced functions generally have the advantage of being more convenient and having a wider range of use than other copying machines. However, the fact that one copying machine can perform many functions leads to the operation of the copying machine becoming more complicated and the console panel on which keys for operation are arranged to be larger.

Therefore, for customers who do not need these functions, t
It becomes necessary to use products that are expensive or prone to operational errors. Therefore, currently, copying machines are being developed that can group customers into several groups and provide functions most suitable for each group. However, if multiple products are brought to market in response to each group, the number of products for special uses will be reduced, resulting in a cost disadvantage. Furthermore, if the customer's usage pattern of the copying machine changes, the machine must be replaced, and the copying machine cannot be used economically.

Although the copying machine has been described above, similar problems occur with other recording devices such as facsimile machines and printers.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a recording device that allows recording functions to be added or changed in accordance with customer requests.

"Means for Solving Problems" In the present invention, as shown in principle in FIG. 1, a memory 11 stores recording function information representing various functions that can potentially be executed as a recording device. and I
A card reading means 12 for reading a card such as a C card or a magnetic card; a comparing means 13 for comparing the recording function information read from the card reading means 12 with the recording function information stored in the memory 11; The recording apparatus is provided with a function execution control means 14 that sets the function matched by the comparison means 13 as an executable function of the recording apparatus.

Here, the information read from the card reading means 12 is not limited to information representing recording function information, but may also read additional control information for realizing functions other than those originally provided in the recording device. It's okay. At this time,
The recording device will be able to perform additional functions based on the read additional control information, thus making it possible to expand its functionality. Here, the additional control information may be control information related to the recording function, or may be control information handling other than the recording function, such as control information for maintenance and inspection of the recording apparatus.

Incidentally, when there are a plurality of cards that can be set in the card reading means 12, it is convenient if identification information indicating the type of recording function information stored therein is displayed on the surface of the card.

Further, the card reading means 12 may be a reader/writer capable of not only reading but also writing. In this case, predetermined data can be written to the card set therein from the recording device side, making it possible to increase the usefulness of the card.

The card used in the card reading means 12 is an IC card.
Various cards such as cards, magnetic cards, memory cards, etc. are possible. Although magnetic cards have a somewhat insufficient capacity to store additional control information, they are inexpensive and suitable for just storing recording function information. A card with a large capacity, such as an IC card, makes it possible to store additional control information, write data from the recording device, etc., and make the use of the recording device more effective.

As described above, in the present invention, since the functions that can be executed by the recording device are selected using a card, it is possible to easily realize a recording device that meets the needs of each customer.

According to the present invention, from the IC card to the recording device main body side! This stored additional control information can be used to realize the most user-friendly recording device for each customer.

``Embodiment'' Hereinafter, a case in which the present invention is applied to a copying machine will be described in detail.

”l First, a table of contents for this example will be displayed.

As shown in this picture! In the second embodiment, the copying machine that can use an IC card has a base machine 21, which has the most basic configuration, and can be enhanced in functionality by attaching desired additional devices. Here, the base machine is a device that is equipped with a one-stage supply tray and a manual feed tray, and can make copies by manually setting an original on a platen glass. The following additional devices can be attached to this base machine.

(1) IC card device 22; The IC card device 22 is a device used to supply necessary data to the base machine 21 using an IC card, or to write data from the base machine 21 to an IC card. When manually editing data (coordinate data) using an editor pad, which will be described later, the editor pad is connected to the IC card device 22 and the manual operation is performed. Note that the IC card device 22 of this embodiment is designed to selectively control the IC card and the editor pad, and it is not possible to manually manipulate data by using both i at the same time.

The IC card used in the IC card device 22 of this embodiment has a 150 type interface and has a memory capacity of 32 kilobytes.

By using an IC card, complex data can be stored on the card as additional control information, making it possible to fully cope with the automation and multifunctionalization of the copier □. For example, by preparing IC cards for each type of industry or customer, it is possible to realize an operating method that suits each owner, even for copiers with complex functions, and anyone can use them easily and without error. Be able to operate a copy machine. Although the device of this embodiment uses only the IC card device 22 as a card reader, a magnetic card reader may be provided as necessary, or other card readers may be provided. It may be prepared.

(2) ADF 23 and DADF 24; ADF 23 is commonly referred to as an automatic document feeder, and feeds the documents one by one onto the platen glass of the base machine 21.
This is discharged after exposure is completed. Exposure of the document is performed only on one predetermined surface j2. On the other hand, D A D F 24 is for duplex,
That is, it is an automatic document feeder for double-sided copying.

In the DΔDF 24, the original is transported with one side facing the platen glass, and the first exposure is performed. When the original after exposure is returned to the tray of the DADF 24, it is turned upside down. As a result, when this document is sent out again, the surface opposite to the exposed surface at the end of j will be exposed. The base machine 21 is capable of copying the front and back sides of copy paper separately using an additional device to be described later.

By enabling the use of the ADF 23 and DADF 24 in the copying machine of this embodiment, it is possible to automatically perform copy operations using various combinations such as double-sided originals and double-sided copying.

The ADF 23 has basically the same structure as the automatic document feeder conventionally used in copying machines, but in the case of the device of this embodiment, the direction of insertion of the document is from the left side when facing the base machine 21. It is shaped so that it does not protrude from the inside.

(3) Ordinary platen 25 and platen with editor pad 26; The platen with editor pad 26 has a structure in which a coordinate manual device called an editor pad is placed on the platen for horizontally collecting documents. A normal platen 25 does not have such a mechanism.

(4) Console panel: There are two types of console panels: a back lift type 27 type and a 28 type with a message display.

Here, the back lift type console panel 27 is
A display board on which a message is fixed at a predetermined position is selectively illuminated from behind with a lamp or the like so that the message can be read.

The console panel 28 with a message display employed in this embodiment is composed of a liquid crystal display element.
It has the advantage that various messages can be displayed at any time without increasing the display area. Which console panel to adopt is determined for each copying machine, taking into account the complexity of the system configuration and operability of the copying machine.

(5) Addition of supply tray; This has the following typical forms. That is, this embodiment does not simply add a large capacity tray as proposed in Japanese Patent Application Laid-Open No. 57-77140, but also realizes a combination of supply trays that better meets the needs of the customer. Such a combination of supply trays is also disclosed in detail in, for example, Utility Application No. 1981-081016 filed by the present applicant entitled "Multi-Throw Sheet Feeding Copying Machine."

(a) Second and third supply trays 31-2.31-:
3; By adding these two supply trays, up to 3
Copy paper of various sizes can be fed to the base machine 21.

(b) Second and third supply trays 31-2.31-3
and intermediate tray 33 Here, the intermediate tray 33 is a tray that temporarily stores the copied paper when copying is performed multiple times on one side of the paper or when copying is performed alternately on two sides. be.

(c) Second and third supply trays 31-2, 31-3, intermediate tray 33, and fourth and fifth supply trays 31-4.
31-5° (d) Second and third supply trays 31-2.31-3
and an intermediate tray 33 and a large capacity tray.

Here, the high-capacity tray is a supply tray that can accommodate several dozen sheets of copy paper.

(5) A storage device for ejected copy paper.

Copy sheets are normally stored in a discharge tray 37, and this system is equipped with a 10-bin sorter 38 and a 20-bin sorter 39. Therefore, by setting one of these sorters, copies can be sorted by up to 110 or 20 distribution destinations.

As mentioned above, in this copier system, the base machine 21
Since various additional devices can be selectively attached to the copying machine, it is possible to provide the copying machine that best suits the user.

Moreover, the functions of the copying machine can be improved in response to changes in the customer's business style.

For example, customers who do not need to enlarge or reduce the original to make copies, or customers who only make a small amount of copies, may use the base machine 21.
It is often appropriate to purchase separately. On the other hand, for customers who make a large number of copies or require complicated copying operations, an intermediate tray 33 or a large-capacity tray is often required. As a means of realizing these various demands, this copying machine system has a structure that allows each additional device to be easily attached and removed.
In addition, independent CPUs (central processing units) are prepared for some of the additional devices, and distributed control is performed by a plurality of CPUs. This not only has the advantage that customers can easily obtain the products they want;
The possibility of installing new additional equipment will introduce new copying possibilities to the customer, making the purchase of this copier system very attractive in terms of promoting the evolution of office processing. will be given.

(2) Software Configuration By the way, the system configuration of the copying machine described above can also be explained as a combination of the software of the copying machine of this embodiment. In other words, this copier can be equipped with various additional devices! Correspondingly, with regard to software, it is now possible to adopt a system configuration compatible with each of these additional devices by selecting recording function information using an IC card and additional control information supplied from the IC card.

The reason for adopting such a configuration is that (i) if a relatively small capacity memory is prepared in the base machine 21 and each necessary control program is stored in an external memory such as an IC card, the control program When the system becomes complicated, a relatively large capacity external memory is required.
There is a problem that external memory becomes expensive. In addition, (ii) if the operation control programs for all of these additional devices were to be prepared in the base machine 21, the memory capacity required for this would become enormous, and (iii) in the future, new When an additional device is developed or an existing additional device is improved, it becomes necessary to replace or expand the ROM (read-only memory) in the base machine 21.

Therefore, this copying machine system introduces the concept of recording function information, allows the copying machine to select functions already prepared by this recording function information, and stores the recording function information in the external memory. ” - to reduce the burden on external memory.And if there is some free space in external memory,
Additional control information is stored here to enable changes or additions to the functions of the copying machine. In other words, this copying machine system can be used in a wide variety of ways, from cards with relatively small storage capacities such as magnetic cards to cards with relatively large capacities such as IC cards with additional memory elements. You will be able to use different cards.

In order to bring out such effects, the base machine 21 has a basic storage area that stores programs prepared in advance on the base machine side to control each operation of the copying machine, and a storage area that stores records imported from an IC card. There is additional storage for storing functional information and additional control information. ADF
Separate recording function information is attached to various programs such as the control program for the D'ADF 23, the control program for the D'ADF 24, and the control program for the console panel 28. Then, when the IC card is set in the IC card device 22 and the recording function information is stored in the additional storage area, the image recording function information is compared, and only the program corresponding to the common recording function information is valid. Control of the copying machine will now be executed. Therefore, for example, base machine 2
Even if the copying machine is equipped with a sorter 38 and a control program for sorting by the sorter 38 is stored in the basic storage area, the recording function information corresponding to this sorter 38 cannot be input from the IC card. Otherwise, sorting control will not be performed.

(2-2> Example of differentiation As described above, in the copying machine of this embodiment, the recording function information stored in the IC card can influence the functions that the copying machine can actually execute. By changing the recorded recording function information on a card-by-card basis, it becomes possible to differentiate the use of the copying machine.This will be explained by giving some easy-to-understand examples.

The first example is when a multi-tenant building is equipped with a copy machine that is shared by multiple companies, or even within a single company or factory, there are copy machines that are shared between different departments. Explain the case. The latter joint use is necessary for budget management, and conventionally, devices such as copy risers have been used to manage usage in each department.

This copying machine has an IC installed in the base machine 21 shown in FIG.
Card device 22, DADF 24, sorter 38, console panel 28, second to fifth supply trays 31-2 to 3
1-5 and an intermediate tray 33, the copying machine has a relatively advanced system configuration. Some users or departments within the community may require a DADF 24 or sorter 38, while others may not require any additional equipment.

If multiple large departments or departments with different usage patterns try to decide on the cost burden of copying machines based only on their own copy volumes, large companies or departments that only make low-volume copies will need copying machines equipped with various additional devices. This makes it difficult to coordinate with large departments or departments that want to make advanced use of copying machines.

In such a case, each person or department should prepare and wipe an IC card according to the usage pattern, and the person or department that wants advanced functions will have to pay more for the basic costs and have many functions. All you have to do is make it available for use. For example, the owner of the most advanced IC card
By operating the copying machine with the card set in the curl IC card device 22, the DADF 24, the sorter 38,
Second to fifth supply trays 31-2 to 31-5, and '
The intermediate tray 33 can be used freely, and office efficiency can also be improved. On the other hand, people who do not need to sort copy paper can cut costs by installing an IC card without a sorting program and using the top bin of the sorter 38 as a paper output tray. .

As a second example, a case will be explained in which a copying company operates a service shop that sells copies using IC cards.

A plurality of copying machines are arranged inside the store, each of which is equipped with an IC card device.

The customer requests an IC card according to the type of service, sets it in the copier of his/her choice, and makes a self-service copy. Customers who are not familiar with copying machines can request an IC card that is programmed with a function to display operating instructions, and by setting this card, various operating information can be displayed on the console panel 28, so that copying operations can be carried out without error. can do. Whether or not the DADF 24 can be used and whether multi-color recording can be performed can be determined by the lent IC card, and it is also possible to restrict the types of devices that can be used, making it possible to manage customers according to the price. Furthermore, since the actual status of the copying process, such as the number of copies and the size of the copying paper used, can be written on the IC card, billing becomes easier, and detailed services such as discounts on copying fees for regular customers are also possible. become.

As a third example, a service using an IC card storing a program for a specific user will be described. For example, in patent offices, when considering patent publications that have been reduced by photolithography, it is necessary to make copies of the original size.
I have a job where I have to make copies at a relatively large enlargement rate of 0.00%. Furthermore, when creating drawings to be submitted to government offices, the original drawings are reduced or enlarged in small increments in order to meet the requests. In addition, departments that make copies of resident records, such as city halls or ward offices, remove information about people who are not eligible for claims and areas that should be kept confidential to protect individual privacy. or create an excerpt.

As described above, users are required to use copying machines in special ways. If the functions of the copying machine were set to satisfy all of these requirements, the console panel would become complicated and the ROM inside the copying machine would become large. Therefore, by preparing IC cards for specific users and setting them, it is possible to realize a copying machine with functions most suitable for that user.

For example, in the case of a patent office, by purchasing a dedicated IC card, it becomes possible to easily select a fixed magnification of 200% in addition to the usual several types of magnification. Furthermore, it becomes possible to set the reduction ratio in steps of, for example, 1% within a range that requires fine adjustment. Furthermore, in the resident's card issuance department, by operating keys such as a numeric keypad, it is now possible to indicate on the display such as the liquid crystal display the type 1 of the resident's card and the fields and items to be deleted. By pressing , only the desired range of the original will be copied, or only the necessary parts will be recorded horizontally.

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

In the copying machine of this embodiment, the DA is mounted on the base machine 21.
DF24 is installed, and an IC is installed at the rear of the top surface.
A card device 22 is arranged.

A console panel 28 with a message display is arranged in front of the top surface of the base machine 21.

Although not shown in the figure, a manual feed tray 41 is attached to the right side of the apparatus, and a sorter 38 for 1O bins is attached to the left side. The manual feed tray 41 is for manual feeding, but it is designed so that a plurality of sheets can be set at the same time and fed sequentially.

It has already been explained that the base machine 21 is equipped with the first supply tray 31-1 as its basic configuration. In the copying machine of this embodiment, the second and third
supply trays 31-2 and 31-3 are arranged, and fourth and fifth supply trays 31 are arranged with an intermediate tray 33 in between.
-4.31-5 is arranged. These supply trays 3
1-1 to 31-4 and the intermediate tray 33 can both be pulled out to the front, improving operability and saving space for the copying machine. In addition, a neat digital copying machine with no protruding ADF (automatic document feeder) or paper feed tray has been realized.

FIG. 4 shows an outline of this copying machine. A photosensitive drum 51 is arranged inside the base machine 21 . The photosensitive drum 51 is a charge corotron (charger) 5
2, so that it is uniformly charged. The photosensitive drum 51 rotates at a constant speed in the direction of an arrow 53 in the figure, and the charged drum surface is exposed at an exposure point 54. Here, a light image of a document (not shown) placed on a platen glass 55 placed on the top surface of the base machine 21 is incident on the exposure portion 54 . For this purpose, an exposure lamp 56, and a plurality of mirrors 57 and optical lenses 58 that transmit reflected light from the surface of the original illuminated by the exposure lamp 56 are arranged. It is set to be scanned.

Now, an electrostatic latent image corresponding to the original is formed on the photoreceptor drum 51 by the image information exposed in a slit shape at the exposure point 54.
is formed. This electrostatic latent image is developed by a developing device 59j to create a toner image. The toner image moves as the photosensitive drum 51 rotates and passes near a transfer corotron (transfer device) 50.

On the other hand, the copy paper 60 stored in the first supply tray 31-1 disposed in the base machine 21 or the copy paper 60 manually fed along the manual feed tray 41 is fed by the feed roll 61-1 or 63. The photosensitive drum 51 is sent out, guided by a conveying roll 69, and passes between the photosensitive drum 51 and the transfer corotron 500. At this time, the toner image will be transferred onto the copy paper 58. The copy paper 60 after transfer is transferred to a heat roll 66
and a pressure roll 670 to be thermally fixed. Then, it passes between the transport rolls 68, 68 and is discharged onto a discharge tray (not shown).

In addition, in this embodiment, the base machine 21 has a DΔDF24.
is installed. Therefore, it is also possible to place both sides of the original on the platen glass 55 one after another. In this case, one side of the originals stacked in the original storage section of the DADF 24 is set on the upper surface of the platen glass 55. Then, when the copying is completed, the original is reset into the original storage unit with the front and back sides reversed, and then fed onto the platen glass 55 again.

Furthermore, in the copying machine of this embodiment, five trays 31-2 to 31-5.33 are installed under the base machine 21, but instead of this, a cabinet may simply be placed to store consumables, etc. . Furthermore, it is also possible to place this copying machine on a desk as a desktop copying machine with the configuration of the base machine 21 unchanged. Of course, it is also possible to attach only the second supply tray 31-2 below the first supply tray 31-1 and place the copying machine with this configuration on a desk in the same way.

FIG. 5 shows an example of the console panel of this copying machine. The details of the display control technology described below by the present applicant are disclosed in detail in "Display device" of Utility Application No. 130320/1980 and "Character display device" of Utility Application No. 61-066170. . For example, Jitsugan Sho 61-13032
No. 0 discloses that a copying machine is provided with a graphic display area in the form of a dot pattern, and suggests that various displays can be performed using this graphic display area. For example, in a copier that can copy parts of a document or move or delete images, an image sensor reads the image of the target area while the document is placed on a platen, and its outline etc. is displayed in a graphic display area. It has been suggested that this should be displayed on the screen, and it is said that this can prevent errors in area settings and operational errors.

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

Now, the console panel 28 has a menu x-display lN71 arranged at its upper part, and each panel part 7
The contents of numbers 4 to 79 are displayed in characters. Among these, one switch 81 and two indicator lamps 82 are arranged on the sorter panel 74, so that it is possible to select a sorting mode when a sorter is connected. The sorting mode includes a stack mode for stacking copy sheets in order, and a collation mode for sorting copy sheets into bins 7-9.

The next function selection panel 75 includes (i) a switch 83 for editing or correcting/confirming the image, (ii) a switch 84 for storing it in the job memory, and (iii)
) Switch 8 for various other copying forms
5 and (1v) switch 86 for making double-sided copies
A display lamp 82 is arranged to indicate whether or not these switches are selected. Here, (i) k
The I collection is a function for inputting data for the shrine collection using an editor etc., and the correction/confirmation is for displaying the manual data on the liquid crystal display section (described later) and checking it, or replacing the data. Refers to function. In addition, (ii) The memory used here is a non-volatile memory consisting of random access memory backed up by a battery.Of course, other storage media such as IC cards, magnetic cards, and floppy disks are also non-volatile. In order to reduce the burden on the operator in operating the console panel 28, this copier can preset settings such as image density and magnification. (iii) When the switch 85 is pressed, character information is displayed on the display panel 79 of the console panel 28, and the desired function is selected from among the "other" functions. You can now choose.

The "other" functions here include, for example, (a) a page quick copy function, (b) a border erase function, and (c) a border function. Among these, (a) the page quick copying function is a function that divides a two-page spread document, such as a bound document, into two pages and copies them in sequence. Also(
The border erasing function is a function that does not copy the image information around the edges of the document, but makes it appear as if a "frame" has been set around the image information. (c) The binding margin function is a function that sets a "binding margin" at the right or left edge of a copy. The binding margin can be set to the desired length,
The numerical value can be entered from the numeric keypad 80 or displayed on the display panel 7.
9 can be selected from the values displayed at this point.

(iv) Finally, double-sided copying is a function that makes copies on both sides of copy paper. When making double-sided copies,
The copy paper 60 on which the first side has been copied is first stored in the intermediate tray 33 shown in FIG. Next, the copy paper 60 is sent out again from this intermediate tray 33, and a copy is made on the side on which no copy was made. Furthermore, with this copying machine, in the case of monochromatic color copying, which will be explained next, copies are made twice on one side. In this case, an arrangement is made so that the front and back sides of the copy paper stored in the intermediate tray 33 are reversed from those in the case of double-sided copying.

At the top of the monochrome color enhancement panel 76 provided below the portion where "monochrome color enhancement" is displayed on the menu display 1ff171 in FIG. 5, there is a display lamp 87 indicating the type (color) of the color developer. There are four placed. In this copying machine, the color developer can be set in one or more colors out of four colors such as red and blue, so the lamp corresponding to the currently set color is turned on.

The remaining part of the monochromatic color emphasis panel 76 includes four switches 88 to 91 and an indicator lamp 82 for indicating which of these switches 88 to 91 is set.
is located. Among these, (i) marking color switch 88 is a switch used when performing marking color.

When this switch 88 is pressed to designate an area to be marked, for example, recording is performed with a light color superimposed on that area, making it possible to obtain an effect as if marking had been performed.

(ii) The continuous shooting color composition switch 90 is used when recording one color in a predetermined area of a copy. For example, if a figure to be expressed in color is placed on the right side of the platen glass 55 (see Figure 4) and an original is placed on the left side and a copy is made, the image information of the original is copied in black, and then a single color image is printed on top of it. The shape will be drawn. At this time,
If a specified figure is formed by halftone dots, a color figure adjusted to a predetermined density by reproduction of the halftone dots is recorded in a predetermined area of copy paper. Another method is to place the name and pattern of the product on one side of the platen glass 55, and place a sheet of paper with the sale price of the product on the other side to simply display the current price.

(iii) When the partial color conversion switch 89 is selected, only the designated area is copied in one color, and the remaining area is copied in black.

On the other hand, if (iv) the single color switch 91 is selected, the original will be copied in one color.

A copy density panel 77 provided below the portion where "copy density" is displayed on the menu display board 71 has a display lamp 8 indicating which of the five copy density levels has been selected.
2 and shift keys 94 and 95 for selecting one of these copy densities are arranged. When the upper shift key 94 is pressed, density setting is performed in the direction of decreasing the copy density, and when the lower shift key 95 is pressed, the density setting is performed in the direction of increasing the copy density. The copy density can be adjusted by changing the developing bias of the developing device 59 shown in FIG. It can be adjusted by changing the amount. In this embodiment, for example, the developing bias can be adjusted in 16 steps.

An automatic density adjustment switch 9 is located below the copy density panel 77.
7 is placed. When the automatic density adjustment switch 97 is pressed, the automatic density display lamp 98 lights up to enter automatic density adjustment mode. In this automatic density adjustment mode, when the document is being scanned, the photoreceptor drum 5 is exposed to light that is reflected from the document.
A part of the light that reaches the developing device 59 is extracted by a half mirror or the like, and the potential of the developing electrode in the developing device 59 is set according to the amount of light.

The magnification/paper selection panel 78 provided below the portion where "arbitrary magnification" etc. is displayed on the menu display board 71 includes the following:
A section for setting and displaying magnification is arranged on the left side, and a section for selecting paper is arranged on the right side.

The part where the magnification is set and displayed includes a magnification display section 99.
is provided. This copying machine can arbitrarily set the magnification (linear magnification) in 1% increments from 50% to 200%, and the set magnification is displayed on a magnification display section 99. To display the magnification, shift keys 101 and 102
There are two types of methods: a method of setting an arbitrary magnification by an operation, and a method of selecting a predetermined fixed magnification.

To set an arbitrary magnification, press shift key 101.1.
Perform operation 02. When the upper shift key 101 is pressed, the magnification increases by 1%, and when the lower shift key 102 is pressed, the magnification decreases by 1%. Shift key 101.
If you keep pressing 102, the magnification will change continuously by 1% during that time.

The fixed magnification is selected by pressing the fixed magnification key 103. The fixed magnifications are displayed on the magnification display board 104, and in this example, they are 141.4%, 86.5%, and 81.6%.
%, 70.7%. In addition, 100% as the same size
can be selected. Which magnification has been selected can be determined by which of the display lamps 82 arranged to the left of the magnification is lit.

In the area for selecting copy paper, there are eight types of display boards 105 displaying paper sizes or paper types, and a shift key 106.10 for selecting one of these.
7 is placed. On the left side of the eight types of display boards 105, a display lamp 82 is arranged to indicate which paper size or paper has been selected. In this embodiment, the following display is displayed on the display board 105.

(b) Bypass tray display; Select this when using the manual feed tray 41 (FIG. 4).

Since this type of conventional manual feed tray manually feeds sheets one by one, it is only necessary to feed the copy paper preferentially from the manual feed tray when manual feed is performed, and there is no need for the operator to select the manual feed tray itself. In contrast, the manual feed tray 41 of this embodiment can set a plurality of copy sheets at the same time. Therefore, if copy sheets are set and fed from the manual feed tray 41, there is a possibility that the feeding will start when a plurality of copy sheets are set. In order to prevent such a situation, the manual feed tray 41 is made to be selected.

<Opening> A3 paper display; Select this when using a tray for feeding A3 size copy paper in the longitudinal direction.

(c) B4 paper display: Select this when using a tray for feeding B4 size copy paper in the longitudinal direction.

(d) A4 paper display: Select this when using a tray for feeding A4 size copy paper in the longitudinal direction.

(e) B5 paper display; Select this when using a tray for feeding B5 size copy paper in the longitudinal direction.

(F) A4 landscape paper display; Select this when using a tray for feeding A4 size copy paper in a direction perpendicular to the longitudinal direction.

()) 8.5 Horizontal paper display; Select this when using a tray for feeding B5 size copy paper in a direction perpendicular to the longitudinal direction.

(H) Standard outer circumference paper display: Select this when using copy paper of a size other than the above.

An automatic paper/magnification selection switch 109 is arranged below the magnification/paper selection panel 78.

When this switch 109 is pressed, the automatic paper/magnification selection switch 109 is selected and a preset combination of magnification and paper size is selected. The operator can know whether a desired combination has been selected from the lighting state of the display lamp 82 on the magnification/paper selection panel 78. If it is not the desired combination, automatic paper/
By further pressing the magnification selection switch 109, the combination is changed.

On the right side of the magnification/paper selection panel 78 is a display panel 79.
is located. A pattern 111 of this copying machine and a liquid crystal display section 112 are arranged on the display panel 79. The pattern 111 is designed to indicate the selected state of the supply tray, the location where a paper jam has occurred, etc. by lighting a lamp. The liquid crystal display section 112 of this embodiment can display sentences including Chinese characters.

The example shown in FIG. 5 of 2 shows that the copying operation can be started and that the set number of copies is one. Further, the liquid crystal display section 112 of this embodiment uses a liquid crystal for color display, so that each designated area is displayed in a designated color.

The following keys or buttons are arranged below the display panel 79.

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

(b) Numeric keypad 80: Used to input numerical values for setting the number of copies, specifying the diagnosis content when diagnosing the copying machine, etc.

(c) Interrupt button 115: Used when continuous copying is in progress and it is necessary to make another emergency copy. It is also used to cancel the interrupt to return to the original copying operation when the interrupt processing is completed.

(d) Stop clear button 116: Acts as a clear button when stopping the copying process midway, when setting the number of copies per copy, and when setting the bins of the sorter.

(E) Start button 117; This is the key to start the copying process.

(to) Selection key 118: This is a key for moving the cursor to the displayed message, that is, a cursor key.

(g) Setting key 119: This is a key (return key) for setting the location specified by the cursor.

As explained above, the console panel of this embodiment is arranged so that the area for basic operations such as paper selection and copy density settings is completely separated from the area for advanced operations such as function selection and monochromatic color enhancement. . In addition, by displaying sentences containing kanji and kana on the liquid crystal display section 112 to assist in advanced operations, the occurrence of mistakes in panel operations is reduced as much as possible.

(4) Circuit configuration of the apparatus FIG. 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 centered around the main CPU 121 is adopted.

This is to enable optimal placement of the controller and provide optimal cost performance. Furthermore, from the perspective of product development for copying machines, modular design can be expected to shorten and improve the efficiency of software development, simplify wiring harnesses, lower costs, and facilitate troubleshooting.

In addition, processing efficiency is improved by distributing processing using multiple CPLIs, so for example, expensive 16-bit CP
By using an inexpensive 8-bit CPU without using the U, it becomes possible to process programs that are complex and require high-speed processing.

Furthermore, such decentralization of processing facilitates model expansion. That is, even when developing a new input/output device or the like, it may not be necessary to modify the program on the main body side (main CPU side), and even if changes are necessary, they can be kept to a minimum.

Furthermore, regarding the printed circuit board on the main body side, there is no need to store unnecessary I10 ports or programs due to the distribution of the CPU. Therefore, the cost of the printed circuit board can be reduced, and the degree of freedom in the arrangement space can be improved.

This copying machine has a main C) 30 in its base machine 21.
(Central processing unit) 121 and C for intermediate image lamp
The base machine 21 is controlled by the PU 122. Here, CPU 122 for inter-image lamp
is a CPU that specializes in controlling the interimage lamp.

The interimage lamp refers to the photoreceptor drum 5 after exposure.
It is used to irradiate light onto the photosensitive material 1 to erase a portion of the electrostatic charge or latent image before development. Conventionally, for example, 85
When copying a size original at the same size, light is irradiated onto an area other than B51J on the photosensitive drum 51 to prevent a toner image from being wasted outside the area. The copying machine of this embodiment has a function of collecting images, etc., as will be explained later. Therefore, it may be necessary to limit the formation of an electrostatic latent image to, for example, a predetermined rectangular or polygonal area, and in order to perform such processing, it is necessary to partially delete the electrostatic latent image. shall be. Interimage lamps are also used for this purpose. In this way, in the copying machine of this embodiment, the inter-image lamp is used in a more highly controlled manner than in the past.
In addition to 21, we decided to use an independent CPU.

Xerox is one of the manufacturers that has introduced such a distributed processing system as a control method for copying machines. and related cited documents are disclosed in detail.

However, the communication method adopted in the present invention is not the "Ethernet method" aimed at high-speed processing adopted in the above-mentioned publication, but a 4800-port current loop method that achieves the same effect. It has become.

In addition, the applicant has developed a CPU 1 for inter-image lamps.
22 is disclosed in detail in Utility Model Application No. 152591/1980 entitled "Image Copying Apparatus" and Japanese Patent Application No. 62/023392 entitled "Image Erasing Device for Copying Machine".

In addition to this, the copying machine of this embodiment is provided with the following CPL', which are connected to communication lines 123 and 124. The main CPU 121 also plays the role of controlling these CPUs and the inter-image lamp CPU 12'g.

(C) Display CPU 127; The display CPU 127 is a CPU used to display various information in kanji on the liquid crystal display section 112 attached to the console panel 28, and to display an area for editing. It is. In the case of the console panel 27 (FIG. 2) of the Battalit type 27, there is no need to perform complicated display control, so a dedicated CPU is not used. Note that when the liquid crystal display section 112 is not used, designation of a figure for editing, etc. is performed using a numeric keypad.

(d) Tray control CPU 128; The tray control CPU 128 controls the fourth and fifth supply trays 31- of the trays added to the base machine 21.
4.31-5, a CPU for controlling the large capacity tray and the intermediate tray 33.

This CPU is placed at the rear of the tray cabinet that accommodates each tray, and controls the connected trays accordingly.

Among these trays, the intermediate tray 33 is independently equipped with a motor for conveying copy paper, and the copy paper stored in this tray requires complicated control such that the storage position differs depending on the size of the copy paper.

The manner in which each tray is controlled by the tray control CPU 128 is as follows.

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

(ii) Control of large capacity tray and intermediate tray 33.

(iii) Independent control of the intermediate tray 33.

(iv) Fourth and fifth supply trays, 31-4.31-
5. Control over only one or both of these.

(v) Independent control of large capacity trays.

(E) Card CPU 129; The card CPLI 129 reads the IC card 131 that stores recording function information and additional control information in order to select or add functions of the copying machine. This is a part for reading and writing when this IC card 131 is used for specifying the coordinates of a document. Further, although the card CPU 1 29 is not used in this embodiment, it can also control the editor pad 132.

The editor pad 132 is used for inputting coordinates, and will be explained in detail later.

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

Note that controlling the copying machine with a control device such as a CPU or a so-called microcomputer is the Xerox company's Sikanda Shaikh (SIKAND＾RSHε1 H).

(ii) Temperature sensor group 136; sensors such as a soft touch sensor for controlling fixing temperature, which will be described later.

(iii) Paper size sensor group 137; supply tray 3
This is a sensor that detects the size of paper stored in the first category. According to the system configuration of the copying machine of this embodiment, copy paper 60 can be sent out from a maximum of five types of trays. Therefore, one supply tray has four
If two sensors are arranged and digital data is used for this processing, it will be necessary to send 4-bit digital data from one tray to the main CPU 121, and a total of up to 20 input ports will be required. Not only that, but the number of connectors and the number of cables that make up the harness increase. This is undesirable from the viewpoints of cost, miniaturization, and reliability.

Therefore, in the copying machine of this embodiment, the state specified by the states of the four sensors for each tray is sent out as analog data. The main CPU 121 side converts the sent analog data into digital data and outputs the copy paper 6 stored in each tray.
Up to 16 types of 0 sizes are to be determined.

Here, the necessary data stored in the non-volatile memo +3 (NVM) 121F includes, for example, (a) a setup value for adjusting the registration of the copy paper 60, and (b) an intermediate image which will be explained in detail later. The amount of erasure of the leading edge of the image by the lamp, (C) Fine adjustment values for vertical and Chinese magnification when the copy magnification is set to 1:1, (d) Binding when copying with a blank space for binding.

Here, various switches and sensors are connected to the filter circuit 121K, for example. Further, the driver circuit 121L is equipped with a well-known D/A (analog-digital) converter and a PWM (pulse width converter), and according to program processing, it can set the developing bias and charge the developing device 59, which will be explained later. Corotron 5

(5) Specific circuit configuration of the copying machine Next, the circuit configuration of the copying machine of this embodiment will be explained in more detail with reference to FIGS. 8 to 13.

(5-1) Surroundings of Photoreceptor Drum FIG. 8 shows the surroundings of photoreceptor drum 51. As shown in FIG.

A charge corotron 52 is arranged around the photoreceptor drum 51.
, an inter-image lamp 141, four types of sub-developing devices 59S1 to 59S4, and a main developing f! device if59M,
) Transphacorotron 50, Butatuku Corotron 14
7. A pre-clean corotron 148, a cleaning device 149, and an erase lamp 155 for static elimination are arranged in this order. Here, the first sub-developing device 59S1 is a developing device that performs development with red toner, and the second sub-developing device 59S2 is a developing device that performs development with blue toner. The third sub-developing device 59S3 is a developing device that performs development using green toner, and the fourth sub-developing device 59S3 is a developing device that performs development using green toner.
4 is a developing device that performs development with brown toner.

Interimage lamps 141 are 12 arranged in a row.
It consists of eight light emitting diodes and one plastic lens placed in front of them in parallel with the light emitting diodes. The plastic lens (not shown) has an aspherical convex portion at a position corresponding to each light emitting diode, and even when adjacent portions of the light emitting diodes emit light, the plastic lens (not shown) remains on the photoreceptor drum 51. Care has been taken to prevent the light from becoming uneven in intensity in the boundary areas. Also, the focus of the plastic lens is on the photosensitive drum 51.
The upper part is moderately blurred. For this reason, even if, for example, triangular shape processing (extraction or deletion of a shape) is performed using the inter-image lamp 141, the difference in level that occurs for each unit of light emitting diode at the boundary of the processing is considerably reduced. will be done.

The inter-image lamp controller 157 performs on/off control of the light emitting diodes of the inter-image lamp 141, which are divided into 128 segments. The cleaning device 149 includes a doctor blade 150 and is configured to scrape off the toner that has been neutralized by the pre-clean corotron 148 from the photoreceptor drum 51.

By the way, in the copying machine of this embodiment, the doctor blade 15
0 comes into contact with the photosensitive drum 51, the main motor 164 starts to be driven 0.2 seconds later. Furthermore, even when the main motor 164 stops, the doctor blade 150 does not immediately separate from the photoreceptor drum 51, but instead separates after 5 seconds have passed. This is because the toner is blown away by the suction action of the vacuum.
This is a device to prevent situations such as contamination of the inside of the copying machine.

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

(a) Color sensor: This is a sensor for determining which developing device uses which color developer is set in each of the sub developing devices 59S1 to 59S4. Even if the sub-developing device 59S is configured with a combination other than the above-mentioned red, blue, green, and brown, the sub-developing devices 59S1 to 59 are controlled by this sensor.
The color type can be detected every S4. The detection output is manually input to the decal detection circuit 230 and transmitted to the main board 230.

(b) Toner sensor; This is a sensor for determining whether or not toner needs to be replenished.

(c) Dispensmoke: This is a motor that stirs and replenishes the toner in the toner box.

The main developing device 59M is for performing black development, and is equipped with a toner sensor and a dispenser smoke. The increase switch 159 is a switch that the operator presses when he wants to increase the amount of toner. When the increase switch 159 is pressed while one of the sub-developing devices 59S1 to 59S4 is selected, the amount of toner in the corresponding sub-developing device is increased. When the main developing device 59M is pressed while being selected, the amount of black toner is increased.

The developer (developing device) selection/solenoid 161 has a total of 5 main developing devices 59M and sub developing devices 59S1 to 59S4.
This is a solenoid for selectively switching between two developing devices. This switching operation will be explained in the next section.

A high voltage power supply system (HVPS) 162 is used to create a parallel electric field inside the main and sub developing devices 59M, 59"St to 59S4 and improve the reproducibility of solid parts (solid black parts) of the original. The full toner sensor 163 is a sensor that detects whether or not enough toner has been collected in the toner collection container.
Alternatively, it is used to drive the conveyance system from the time of alignment (registration) of the conveyance timing of the copy paper 60 to the time of ejection.

(5-2) Developing Device Switching Mechanism FIG. 9 is a waveform chart showing switching timing between the right main developing device and the sub developing device in this embodiment. This figure shows an example in which the first sub-developing device 5951 performs red color development, and the second time, the main development device performs monochrome development. Copy machine start button 1
17 (Fig. 5) is pressed to start the copying operation, the main motor 1 starts from time t as shown in Fig. 5 a.
64 is driven. The driving of the main motor 164 and the two developing devices 59S1, 59M continue until time t3 when the copying operation is completed.

The figure shows the drive timing of the development selection solenoid 161. Dev selection solenoid 161
is the first sub-developing device! ! ! 59 S It is excited until the red copying operation by 1 is completed.

In this device, the development selection solenoid 161 is energized so that the lever comes into contact with the peripheral surface of a clutch (not shown). The clutch receives driving force from the main motor 164, and starts rotation of five sets of cams (not shown) each having one protrusion that is offset by 72 degrees. One of these protrusions is the first sub-developing device! 59
When applied to S 1 , this forces the first sub-developing device 5931 in the direction of the photoreceptor drum 51 . At this time, the protruding portions of the remaining cams are at the farthest position from the main developing device 59M and the other sub-developing devices 59S2 to 59S4, and in this state, the main developing device! 1259M and other sub-developing devices 59S2 to 59S4 are located away from the photosensitive drum 51.

Projections are arranged at five locations on the circumferential surface of the clutch, and when the lever abuts against the corresponding projection, the corresponding projection of one cam is most strongly pressed against the first sub-developing device 59S1. do. Then, development is performed at this position using the corresponding red color toner. However, in this device, the main developing device 59M is arranged close to the photosensitive drum 51 in the initial state, so the development of colors such as red occurs at time t1.
Instead of starting immediately, the operation waits for one second. At this time, the above-mentioned cam is used as the first sub-developing device 59S1 (instead of the main developing device 59M).
Alternatively, other sub-developing devices 5982 to 59S4) are set on the photosensitive drum 51.

When the copying operation by the first sub-developing device 5951 is completed, the five cams mentioned above move for one second from time t2, and when the protrusion of the monochrome cam is positioned by the lever, the main developing device 59M is set on the photosensitive drum 51. After this, monochrome development will be performed.

Incidentally, the above is a case where marking is performed with one color, red, but when marking is performed with multiple colors, the sub-developing devices 5951 to 59S4 are used in a predetermined order.
Applicable ones are selected in order, and monochrome development is performed after these are completed.

In contrast, FIG. 10 shows, for reference, a case in which monochrome development is first performed and red color development is performed later. Figure a shows the operation of the main motor 164.
The diagram also shows the operation of the development selection solenoid 161. In the case of FIG. 10, development is first performed by the main developing device 59M, so there is no need to wait for one second at this point. However, once the monochrome development is completed as the second development, it is necessary to take one second to set the main development device 59M relative to the photosensitive drum 51 again.

(5-3>Optical system Next, the relationship between the optical systems will be explained using FIG. 11.

A carriage (not shown) on which lenses, mirrors, etc. are arranged is reciprocated by a carriage motor 171. This carriage motor 171 is configured by a step morph. Position control when the carriage returns to the home position is performed by the registration sensor 172.

The registration sensor 172 is used to adjust the timing between the optical system and the conveyance of the copy paper 60! This is also used.

That is, an actuator for blocking the transmission of light is disposed on the carriage, and when the carriage moves, the registration sensor 172 detects the temporary blocking of the light beam due to the light blocking by this actuator.

This detection signal is used to determine the position or timing for performing registration, or to determine the home position when the carriage returns.

The density control sensor 173 is a sensor that controls the copy density of the original. As described above, the copying machine of this embodiment controls the copy density by simultaneously adjusting the amount of charge applied to the photosensitive drum 51, the amount of exposure of the image, and the bias of the developing electrode.

The lens/mirror sensor 174 is a sensor that controls the movement of the optical lens 58, mirror 57 (Fig. 4), etc.
It is composed of one detection element.

The lens/mirror motor 175 has also been changed from a conventional copying machine in which the lens 64, mirror 57, etc. are driven separately to a type in which they can be driven in common.

The exposure lamp 56 has been described above. Optical system fan 1
77 is a fan for cooling the optical system and removing heat from the platen glass 55. The document sensor 178 is a sensor provided to detect the size of the document.

(5-4) Fixing Device Next, the relationship of the fixing device will be explained. The fixing device is the first
This is shown in Figure 2.

The base machine 21 of this embodiment has a main fuser lamp 181 and a sub-fuuser lamp 1 in the heat roll 66.
Two types of fuselage lamps, 82 and 82, are installed. The sub-fuser lamp 182 is shorter than the main fuser lamp 181, and is arranged at a position slightly offset from one end of the main fuser lamp 181. In the copying machine of this embodiment, the copy paper 60 is positioned along one side of the platen glass 55, which is a so-called corner register.
Since a corner registration (corner registration) method is adopted, the required amount of thermal energy in the axial direction of the heat roll 66 varies depending on the size of the copy paper 60 used. In order to correct the resulting deviation in temperature distribution in the axial direction, the sub fuser lamp 182 is controlled to be energized according to the size of the copy paper 60.

By employing the sub fuser lamp 182, it is possible to sufficiently prevent temperature fluctuations in the fixing device.

The fixing device includes a user exit sensor 184 and an S/T-3.
(soft touch sensor) 185 are both connected. Here, the user exit sensor 184 prevents the copy paper that has passed between the heat roll 66 and the pressure roll 67 from being accidentally caught in both rolls 66 and 67.
This is to detect whether or not the paper is ejected onto the ejection tray.

5-T-3165 is a temperature sensor for fuser lamp 181°182.

(5-5) Control of the console Next, referring back to FIG. 11, the control relationship of the console will be explained.

The console control unit 191 is equipped with a message ROM 192 for displaying messages in Chinese characters. Also, an IC card device (IC card reader/writer) is used to read and write the IC card 131 (FIG. 6) and connect the editor pad 132 (FIG. 6) via the interface port 193 in the console control unit 191.
22 can be connected. As already explained, this IC card device 22 has a card CPU 129 (
(Fig. 6). Console control unit 1
91 is connected to the main board 201. The main CPLI 121 described above is mounted on the main board 201.

(5-6) Pilling Counter Next, the pilling counter used for collecting copying fees will be explained with reference to FIG.

Since the base machine 21 of this embodiment can make copies in five colors, it is equipped with two types of pilling counters. Among these, the main pilling counter 211 is black and white,
To count the number of copies made regardless of color. The count value of the main pilling counter 211 is also used as data for counting control when an accessory 212 such as a coin kit or key counter is attached to the copying machine. The subbilling force r' tank 213 is used to count the total number of colors used in each copy when color copies are made.

(5-7) Power supply Next, the power supply relationship will be explained with reference to FIG. 12.

The base machine 21 is connected to a 100V (volt) commercial power source. Also 115V60 for overseas use
It is also compatible with Hz and 220V50Hz power supplies. The power supplied from the outlet 221 is 15
It reaches the main switch 224 via an ampere circuit breaker 222 and a noise filter 223. The output side of the main switch 224 is connected via an interlock switch 225 to an AC driver 226 and fixing control.

The power is supplied to the control element 227 and the DCIEil 1228 as power. Furthermore, the DADF 24 and the intermediate tray 33

(FIG. 8) (Y) Main board 201 (FIG. 8, etc.) (5-8) Conveyance system Next, the copy paper conveyance system will be explained using FIG. 13.

The first to fifth supply trays 31-1 to 31-5 have no paper sensors 231. A size sensor 232 and a clutch 233 are each provided. Here, the no-paper sensor 231 is a sensor for detecting the presence or absence of copy paper in the supply trays 31-1 to 31-5. This copier can load copy paper of the same size into multiple supply trays, and in this case, when one supply tray runs out of copy paper, the same size copy paper is automatically loaded from the other supply trays. It is now possible to send it to The size sensor 232 is a sensor for determining the size of copy paper stored in the tray. Further, the clutch 233 is connected to each feed roll 61.
-1, 61-2, . . . is a component for on/off control of the drives.

Copy paper is fed by a dedicated feed motor 2.
It is done by 35. A step motor is used as the feed motor 235. A feed sensor 236 detects whether copy paper is being fed normally. The gate solenoid 237 is a registration solenoid for aligning the leading edge of the copy paper once sent out. This gate solenoid 23
7 is different from a normal solenoid of this type, and performs control such that when energized, the gate opens to allow copy paper to pass through.

That is, in a standby state where copy paper does not arrive, power is not supplied to the gate solenoid 237 and the gate remains open. Just before the copy paper arrives, gate solenoid 237 is energized and the gate closes to prevent passage. Then, when the conveyance of the copy paper is resumed at a predetermined timing, the energization is stopped and the gate is opened. By performing such control, there will be less fluctuation in the gate position when the leading edge of the copy paper is blocked from passing, and even if the copy paper is pressed against the gate with a relatively strong force, its position will be maintained. Can be done accurately.

The manual feed switching solenoid 238 is connected to the first feed tray 31
This is a solenoid for switching the drive between the conveyance roller for copy paper sent out from -1 and the conveyance roller for copy paper manually fed from the manual feed tray 41. The manual tray sensor 239 is connected to the manual tray 41
This sensor is used to detect the presence or absence of copy paper when sending multiple sheets of copy paper. Tray interlock 2
Reference numeral 41 denotes an interlock switch attached to a mechanism that is opened and closed to remove a copy paper jam when it occurs. The tray path sensor 242 is a sensor that detects the copy paper 60 sent from the second and third supply trays 31-2.31-3. It is placed near the joint.

(5-9) DADF The DADF 24 will be specifically explained with reference to FIG.

DADF24 is the platen glass 55 of the base machine 21
is mounted on top of. The DADF 24 is equipped with a document tray 252 on which a document 251 is placed. The originals 251 are stacked on the original tray 252 with the first side to be copied facing downward.

A tart pad 254 and a feed paddle 255 are arranged on the document feed side of the document tray 252, and the documents 251 are fed one by one by these. The sent out document 251 is moved by a driving roller 256 and a driven roller 25.
7, it passes through the S-shaped withdrawal part 258 and is pressed against a branch guide 261 arranged at a position where this S-shaped conveyance part 258 and the vertical conveyance part 259 intersect. Branch guide 26
1 is thereby released, and the original 251 is transferred to the reversing progressive feeding section 26.
It is transported to the second side.

When the rear end of the document 251 passes through the branch guide 261, the branch guide 261 is closed toward the S-shaped conveyance section 258 by the action of a spring (not shown).

At this time, passage of the original 251 is detected by a sensor (not shown) arranged near the branch guide 261. ,
By outputting this detection signal, the document reversing drive roller 264
rotates in the opposite direction. As a result, the conveyance direction of the document 251 is reversed, and the conveyance direction is changed to a direction substantially perpendicular to the platen glass 55.

Thereafter, the original 251 is conveyed while being positioned by the oblique slip paddle 265 with one side of the original 251 abutting against a side positioning guide (not shown). Then, it is transported to a correct position on the platen glass 55 by the endless transport belt 266. In this way, the original 25'l
The above-described copying operation is performed on the first page.

After the exposure of the first side is completed, the original 251 is transported in the direction of arrow 267 by the endless transport belt 266. Then, by the action of the exit side guide 268, when copying only this first side is performed, the vertical conveyance section 268
9 is selected, and the original 251 is stored in the original receiving section 271.

On the other hand, if a copy is to be made on the second side opposite to the first side, the horizontal conveyance section 272 is selected. The original 251 sent to the horizontal beam feeding section 272 is moved in the opposite direction of the arrow 267 by the conveying roller 273! The paper is transported in the j direction, and is transported through an S-shaped transport section 258 by a driving roller 256 and a driven roller 257. At this time, the lower surface of the document 251 is the second surface, which is opposite to when it was stored in the document tray 252. Therefore, in a state in which the document 251 is fed onto the platen glass 55 using the same conveyance procedure as described above, a copying operation is performed on the second side.

After the exposure of the second side is completed, the original 251 is moved to the exit side guide 268.
Thus, the document is sent to the vertical conveyance section 269, and the document receiver is discharged to the section 271.

(5-10) Sorter The 10-bin sorter 38 will be specifically explained with reference to FIG.

FIG. 15 shows the appearance of the sorter.

The 10-bin sorter 38 has 10 bins 281 that can be moved up and down as a unit. Sorter body 282
includes a drive source (bin motor) to perform this lifting and lowering,
A cam and a cam switch for controlling the movement position of each bin, and a down limit switch (both not shown) for detecting that the bin 281 has reached the lower limit position are arranged.

The copy paper 60 is transported by conveyor rolls 68 and 68 shown in FIG.
It advances in the direction of arrow 284 and is fed into the sorter main body 282. Then, at that point, it is discharged to the bin facing the conveyance path. Note that depending on the sorter, the discharge path may be switched by not raising and lowering the bins 281 but by raising and lowering the sorter body 282 instead.

The mode selection of the sorter 38 is performed by operating the sorter panel 74 shown in FIG.

(5-11) Intermediate tray Next, the intermediate tray 33 will be explained.

FIG. 16 shows a conveyance system centered on the intermediate tray 33.

The copy paper 60 that has been thermally fixed by the heat roll 66 in the base machine 21 is controlled by a duplex gate solenoid 351 also placed in the base machine 21 to output it to the output tray side or feed it to the intermediate tray 33 side. be exposed. A first duplex path sensor 352 is located on the pace machine 21 side, and a second duplex path sensor 353 is located on the second supply tray 31 side.
Paper jams are detected for the copy paper 60 before it reaches the intermediate tray 33.

By the way, the intermediate tray 33 does not have a feed roll for feeding the leading edge of the copy paper 60 to the leading edge of the tray. Depending on the size of the copy paper 60 sent there, it is conveyed to a desired position and "dropped" into the tray.
3 duplex solenoid gates for 35
5 to 357 are arranged. These duplex solenoid gates 355 to 357 are configured to selectively operate the solenoids depending on the size of the paper to be fed, thereby opening and closing the corresponding gates. The skinny roll solenoid gate 358 controls one corner of the leading edge of this "falling" copy paper 60 to hit the leading corner of the intermediate tray 33, and separates each sheet of the copy paper 60 that is fed. This is a gate that aligns the tips. Each time this operation is completed for one sheet, the main pilling counter 21
A count up of 1 is performed.

As already explained, the intermediate tray 33 has tray control C.
It is designed to be controlled by PU 12 g,
The copy paper is conveyed under the control of a duplex motor 361 (FIG. 8). The duplex no-vapor sensor 362 is a sensor that detects the presence or absence of the copy paper 60 in the intermediate tray 33. Duplex feed clutch 363 is a mechanism for performing on/off control of a drive source for feeding copy paper 60.

The inverter gate solenoid 364 is a solenoid that switches between making double-sided copies, marking the same side in multiple colors, and making composite copies. That is, when the inverter gate solenoid 364 is positioned in the direction shown in FIG. After falling, it is then transported upward by transport rolls 367 and 368. And the inverter
The conveyance direction is changed to the right in the figure before the gate solenoid 364, and the paper is stored upside down in the intermediate tray 33. If conveyance is restarted in this state, a double-sided copy will be made.

In contrast, the copy paper 60 that has been conveyed downward
When the transport direction is changed to the right in the figure before the inverter gate solenoid 364, the paper is stored with the original front side facing upward again. If conveyance is resumed in this latter state, a copy will be made again on the same side. Generally, when marking is performed in N types of colors, one sheet of copy paper 60 is stored in the N-time printing tray 33, and then developed in monochrome and then discharged.

The duplex feed sensor 369 is a sensor for detecting whether copy paper fed from the intermediate tray 33 is jammed.

(5-12) Editor Pad The editor pad 132 will be specifically explained with reference to FIGS. 17 and 18.

Of these, FIG. 17 shows the system configuration of a copying machine equipped with an editor pad. That is, in the configuration of the copying machine shown in FIG. 3 as an embodiment of the present invention, the DA

The following FIG. 21 shows the relationship between basic control information and additional control information in the copying machine of this embodiment. A program P is prepared from the beginning on the base machine 21 side to control various operations of the copying machine. -Pw is stored in the ROM 121D (FIG. 7) as a basic storage area in association with the recording function information F0 to FN. Further, recording function information FL-F is read from the IC card 131 set in the IC card device 22.

and various programs X as additional control information.

~XM are written in the RAM 121E (FIG. 7) as an additional storage area.

Here, the first IC card 131-1 that can be set in the IC card device 22 has recording function information Fo =
Fs SF- and F13 are stored, and no additional control information is stored.

The second IC card 131-2 also contains recording function information F.
o to Fs, Fa, Flo, and F'ts are stored, and xl is stored as additional control information.

Further, the third IC card 131-3 stores recording function information F0 to F+2 and FI4, and stores additional control information X0 to X3.

The following Tables 1 and 2 are recording function information FO~Fll.
This represents the relationship between the code information stored in the IC card 131 as information representing them. Here, Table 1 is recording function information F.

~F% is associated with numerical information, and Table 2 is expressed using alphanumeric characters. For example, alphanumeric characters are ASCII
However, it is the second in terms of sharing the code between models.
The method shown in the table has the advantage of being less prone to errors.

Table 1 Table 2 Now, when the information stored in each IC card 131-1 to 131-3 is analyzed, the results are as follows.

(i) The program P corresponding to the recording function information F7 stored in the first IC card 131-1 is related to the setting of one type of fixed magnification (100%; same magnification). The program P8 corresponding to the recording function information F8 stored in the second IC card 131-2 is 100
In addition to the fixed magnification of %, there are 11 types of reduction magnification (50%, 61%
, 70%, 81%, 86%, 93%, 115%, 122
%, 141%, 163%, 200%). In addition to these fixed magnifications, the program P9 corresponding to the recording function information F stored in the third IC card 131-3 has 150
This is a control program that can set any magnification in 1% increments from % to 60%.

(ii) Recording function information Fo is used for normal copying and A
This corresponds to the program P0j as a control program regarding one-page copying by the DF 23 and DADF 24, and is commonly stored in each of the IC cards 131-1 to 131-3. Recording function information F stored in the second IC card 131-2 and the third IC card 131-3. The program PIG corresponding to the above is a function for sequentially copying two facing pages of a bound manuscript (snap copy function). In addition, the third IC card 1
The program P I+ corresponding to the recording function information Fl+ stored only in the DADF 31-3 is for the double-sided recording function by the DADF 24.

(iii) Program P corresponding to recording function information F2
2 is the main developing device 59M or the sub developing device 59
It deals with one-color development control using S. The program P12 corresponding to the recording function information F1° stored in the third IC card 131-1 is a program for marking documents in two colors or in multiple colors, such as marking color processing in which specific areas of a document are marked in color. Handles control information for creation.

(iv) Program P corresponding to recording function information F13
Reference numeral 13 relates to restrictions on starting copying operations. This program PI3 allows copying work to be started between 9:00 a.m. and 12:00 p.m. and between 1:00 p.m. and 5:00 p.m. At times other than this, the start button 117 (FIG. 5) does not function even if the user attempts to perform a copying operation. Program P corresponding to recording function information F14
Reference numeral 14 is a program that does not impose any restrictions on the start time of the copying operation, which was restricted in the program P13. That is, the first I in which the recording function information Fll is stored
The owner of the C card 131-1 is prohibited from copying work during lunch breaks and overtime hours, thereby preventing unauthorized copying or personal copying of confidential documents during these hours. The program PIS corresponding to the recording function information FI5 stored in the second IC card 131-2 is
It handles information for prohibiting copying operations after that time, and for writing data regarding the date and time of copying operations and the number of sheets into the IC card 131-2 itself.

(v) Additional control information X. is the control information regarding the reduction ratio, and unlike the specified program P, it changes from 200% to 5.
This is a control program that can set any magnification in 1% increments up to 0%. Additional control information x1 to x3 relates to the manual form of coordinate data used for marking color processing and the like. Among these, the additional control information Xli deals with control for performing coordinate manual operation using the numeric keypad 80.

Additional control information X2 deals with control of coordinate input from editor pad 132. Additional control information X3 deals with control such that coordinate data can be input from another IC card.

In this way, the third IC card 131-3 stores the recording function information and additional control information that are most widely used, and the second IC card 131-2 stores the recording function information that is most widely used. Functional information and additional control information are stored. The first IC card 131-1 is a card that is given to a part-time worker who performs copying work, and stores sufficient recording function information for simple copying work. The surface of the third IC card 131-3 is colored (for example, gold), and the second IC card 13 is colored, for example, silver.
1-2 and the first IC card 131'- colored in red.
1 and can be distinguished at a glance.

In this copying system, an IC card or the like whose surface is colored green (not shown) is also provided, and is used to realize other functions such as self-diagnosis of the copying machine.

Note that on the surface of the storage medium such as the IC card 131, functions that can be used by this means are displayed at the same time as symbols representing positions such as department manager, section manager, and ordinary employee, such as [phase], ■, ■, etc. You can do it like this. For example, if ■m is written on the surface of the storage medium, you can use any function at any time, but ■, -・I+
If it is marked, reduce and enlarge the original, ADF 23 and D
ADF 24 can be used and no further functions can be used.

(6-2) Flow of Control As explained above, in this copying machine, the IC card device 22
The functions of the copying machine are selected or changed depending on the type of IC card 131 set in the copying machine.

In this way, the most appropriate copy form for each owner of the IC card 131 will be realized.

FIG. 22 is for explaining the writing operation of recording function information and additional control information by inserting an IC card. When the power of the copying machine of this embodiment is turned on, a message "Please set the rIC card" is displayed on the liquid crystal display section 112.

When the IC card 131 is set in the IC card device 22 (step 2; Y), recording function information and additional control information are loaded (step 2). If there is no additional control information, only recording function information will be loaded. Main CPU 21 is RAM 121E
When the loading is completed, the recording function information written in the ROM 121D is compared with the loaded recording function information (step 2). Then, the program for the matched recording function information is put into an executable state ((step ■). If there is no problem such as a jam (paper jam) in the copying machine, the LCD display allSl.
At step 12, a message "Copy possible" is displayed (step ■).

In this state, the operator sets the copying machine to the desired copying mode and copying conditions, and presses the start button 117 (step 2). When the start button 117 is pressed, the main CPU 121 determines whether the currently set copying mode and copying conditions are executable with the current copying machine (step 2). and if it is practicable,
Execute the copying operation (step ■).

On the other hand, if copying cannot be performed under the current conditions, such as when the first IC card 131-1 is set during lunch break (step ■; N), the LCD display section 112 displays " The message "You can copy" disappears, and the reason why copying is not possible is displayed instead (Step ■). For example, if the first IC card 131-1 is set to copy-prohibited time, a message such as "It's break time. Please wait until working hours" or "You cannot copy unless another IC card is set" is displayed. be exposed. Furthermore, if a sorting mode is specified even though recording function information that cannot be sorted by the soak 38 is loaded, a warning message saying "sorting is not possible with this IC card" is displayed.

On the other hand, when the operator changes the mode etc. (step 2; Y), a check is made to see if copying is possible in the changed state (step 2). If copying is possible, the copying operation will be executed (step ■), and if the copying operation still cannot be performed, the reason why the copying operation cannot be performed will be displayed for the new mode. Steps to be taken (■).

(6-3) Concrete example of control Now, let us explain in detail an example in which the IC card 131 is set in the IC card device 22 and a copy operation is performed by setting a wide range of reduction ratios using the additional control information X1. explain.

FIG. 23 shows the main part of the circuit configuration of the IC card connection part in the IC card device. The IC card device 22 has a card CPU 12 as shown in FIG.
It has 9. The card CPLI 129 includes a RAM (random access memory) 511 with a storage capacity of 4K (kilo) bytes and a ROM (read only memory) 512 with a storage capacity of 4 bytes.

Here, the ROM 512 is a memory that stores a program for controlling the IC card device 22, and the RAM 51
1 is a working memory for temporarily storing various data.

The card CPLI 129 is connected to two serial to parallel converters 513 and 514. The first serial-parallel converter 513 transmits and receives serial data to and from an IC card set in the IC card device 22, and transmits and receives parallel data to and from the card CPU 129. Second serial-parallel converter 5
14 transmits and receives serial data to and from the base machine 21, performs serial-to-parallel conversion or parallel-to-serial conversion, and transmits and receives parallel data to and from the card CPU 129. Two clock generation circuits 515 and 516 are prepared in the IC card device 22, and the first clock generation circuit 515 has a 4.9152M clock generation circuit.
A Hz black signal is supplied to the IC card. Further, the second clock generation circuit 516 supplies a 7.3728 MHz clock signal to the card CPLI 129.

The card CPU 129 connects to the IC via the output port 518.
■ Voltage on the card. and VPP, and also supplies a reset signal R3T. Further, an insert signal INS and a card presence signal CARD are supplied from the IC card via an input port 519.

FIG. 24 corresponds to FIG. 7 and shows the IC card 131.
This figure shows the flow of data when the IC card is set in the IC card device 22. When the IC card 131 is set in the IC card device 22, the base machine 21 detects this and starts reading data with predetermined timming. At this time, data is transferred from the IC card 131 to the IC card device 22 at a transfer rate of 96008 PS (bits/second). In the IC card device 22, this is 48
The data is converted to a speed of 0.008PS, and a large amount of data is transferred to the main CPU 121 as serial data.

Here, large-capacity transfer means that the main CPU 121 temporarily suspends data exchange with each additional device while not performing copy control on the base machine 21 side, and transfers data to and from the IC card device 22. This means devoting oneself to the transfer of information.

This large-capacity transfer is disclosed in detail in Tokuko No. 1982-097440, filed by the applicant of the present patent on April 22, 1986, under the title "Serial Communication Control Method."

Note that if the additional control information is not stored in the IC card 131, such large-capacity transfer may not be performed, and the recording function information may be communicated by normal time-division transmission. In this case, communication is possible even when the copying machine is in the process of copying.

The recording function information and additional control information of the IC card 131 sent to the main CPU 121 are stored in the RAM 121E. Then, the magnification control operation is started by the magnification control program stored in the ROM 121D,
The various parameters for magnification control written in the RAM 121E are used to start copying at a desired magnification.

For example, when the third IC card 131-1 is set, a data table of 151 levels of reduction ratio from 50% to 200% in 1% increments is read out, and the shift key 101 shown in FIG. .102 performs control for specifying the reduction ratio such that the reduction ratio changes in 1% increments.

In the data table for the 151 stages of reduction ratio, the following various parameters are written as values corresponding to each stage.

(a) Position data of the optical lens 58 (FIG. 4).

(b) Position data of a plurality of mirrors 57 (FIG. 4).

(c) Control data for an optical motor for moving a carriage (not shown).

(d) Data regarding on/off control of the interimage lamp 141 (FIG. 8).

(e) Data for setting the light amount of the exposure lamp 56 (FIG. 4).

(f) Data regarding on/off control of the side erase lamp (not shown).

(g) Data regarding timing of carriage turn.

Therefore, for example, when a reduction ratio of 55% is selected, the optical lens 58 etc. are moved to the corresponding position, the timing of on/off control of the inter-image lamp 141 is determined in relation to the size of the document, and - exposure line Control is performed such that the light amount of 56 is reduced by a predetermined amount compared to the same magnification.

On the other hand, when the second IC card 131-2 is set in the IC card device 22, the recording function information FB
The reduction ratio is controlled based on the following.

In this case, the 100% fixed magnification already stored in the ROM121D and 11 types of reduced magnification (50%, 61%) are used.
%, 70%, 81%, 86%, 93%, 115%,
122%, 141%, 163%, 200%) will be referred to and the copy operation will be performed for these reduction ratios.

"Modification" In the embodiment described above, each IC card has multiple functions, and the optimal card is assigned according to the status and occupation of the owner. Each IC card may have a single function (recording function information or additional control information), and the IC card may be used differently depending on the required function. In this case, the functions that can be realized may be displayed in text on the surface of the IC card, such as ``for self-diagnosis'', ``for displaying messages in English'', ``for customer program function'', etc.

FIG. 25 shows the main part of the operation of the copying machine in this modification. When the recording function information in the IC card is loaded into the RAM 121E of the copying machine main body (step 2), if the self-diagnosis function is loaded (step 2: Y), the copying machine is set to the self-diagnosis mode.

In this self-diagnosis mode, the numeric keypad 80 shown in FIG.
By manually inputting a number corresponding to the location of the diagnosis, the drive control of that part is performed, and a serviceman inspects whether it is operating normally (step ■). Furthermore, in the production line of copying machines, this self-diagnosis mode is used to inspect various parts and adjust various parameters.

FIG. 26 shows the operation for specifying diagnostic work in the self-diagnosis mode. In FIG. 26, when the self-diagnosis (DIAG) mode is set <Step ■>, the LCD display section 112 displays the message "Self-diagnosis mode. Please input the chain code" (Step ■). . Here, the chain code is a two-digit code, which together with the next two-digit function code will specify the diagnosis target.

When the operator enters the chain code manually from the numeric keypad 80 and presses the start button 117 (step ■), the chain code is displayed on the liquid crystal display section 112, and a message "Please enter the function code" is displayed. (Step ■). Operator power (operate the numeric keypad 80, enter the function code you want to test, and press the start button 117. Step ■)
, depending on its content, input test (step ■)
, output test (step ■), or adjustment mode (step ■) is specified, and the contents of each test are displayed on the liquid crystal display section 112 (steps ■ to 0).
At the same time, the corresponding tests will be executed. Note that when a numerical value that does not correspond to the function code is entered manually, a message "No such code exists" is displayed on the liquid crystal display section 112, and self-diagnosis is not performed.

By the way, in the copying machine of this embodiment, if a trouble such as a paper jam occurs during copying, the details of the trouble and data such as the size and number of copies of paper involved at that time are written into the non-volatile memory. It looks like this. Then, when the serviceman sets the copy limit to self-diagnosis mode and sets the mode to read these data, the contents are displayed on the liquid crystal display section 112 and are also written to the IC card 131 as necessary. It is now possible to That is, the operator uses the liquid crystal display section 11
It is not necessarily necessary to copy the contents displayed in step 2 into a notebook, etc., but instead store this data on an IC card for service personnel, take it back to the office, and load it into a trouble analysis computer for analysis. You can also print out the data you need.

Returning to FIG. 25, the explanation will be continued.

When the recording function information is loaded from the IC card for displaying English messages (step ■; Y), the sentences that are normally displayed on the liquid crystal display section 112 as sentences mixed with kanji and kana are changed to English using alphabets. will be displayed (step □). As a result, even when a foreigner uses a copying machine installed in Japan, he or she can receive operating instructions and check the displayed contents. If the copying machine is equipped with a comparison table for Japanese messages and English messages, as well as a comparison table for other languages such as Spanish V, I
By preparing C cards for each of these countries, not only can messages be displayed in the language of each country, but also the cost can be reduced by using a common copying machine.

In addition, when the recording function information is loaded from the IC card for the customer program function (step ■; Y),
The copier is set to customer program mode (step ■). In this customer program mode, (a)
Selecting the type of supply tray that is initially set when the copier is turned on, i.e., the type of copy paper to be used preferentially, (1) Selecting the copy density, (3) Finishing the copying operation. Achieving copying operations that meet the customer's requests, such as the set time from when the power saving mode is activated until switching to the power saving mode, whether or not switching to the power saving mode is prohibited, and (d) the reduction ratio that is set as a priority. Various data for this will be written into the nonvolatile memory 121F (FIG. 7). Depending on the user of the device, this customer mode may be further subdivided and managed using IC cards corresponding to the subdivisions. When the copying machine is set to the customer program mode, necessary messages, manual input values, set values, etc. are displayed on the liquid crystal display section 112.

In this modified copying machine, when a new function is developed or becomes necessary, an IC card with that function programmed can be purchased, and the functions of the copying machine can be changed or improved using this. Can be done. For example, if additional control information is loaded using an IC card to implement function X (step ■; Y
), it becomes possible to set the mode to realize the function X. If the function stored in the IC card inserted into the IC card device 22 is a function that is not compatible with the copying machine, an error display is displayed on the liquid crystal display section 112 etc. (step 0) due to the implementation described above. Similar to the example.

FIG. 27 is for explaining the function setting of a copying machine and the registration work of a password in a copying machine system in which a password is set in an IC card.

By setting or changing the password to a desired one, even if there is a change in the operation of the copying machine, it becomes possible to easily deal with the change.

When the operator turns on the power to the copying machine (step 2), the CPU in the copying machine monitors whether an IC card is set in the copying machine (step 2). With the IC card set, the copier determines whether a PIN code is registered in the IC card (step ■
). If it is registered, the PIN code is loaded into the copying machine (step ■), and it is checked whether the manually entered PIN code is already registered in the copier (step ■). .

The registered password code is then permitted to execute the function or mode (step ■). Then, when the IC card is removed from the copying machine (Step 2; Y), the function or mode set by the password is canceled (Step 2). However, depending on the device, even if the IC card is removed from the copying machine, the function or mode of the copying machine may be maintained until the copying operation is completed.

On the other hand, if the entered PIN code is not registered in the copying machine (step ■; N),
The entered PIN code is canceled (step ■). In this case, the copying operation will be performed with the same function or mode as if no IC card was set.

Now, when setting a new PIN code on the IC card, the PIN code has not yet been registered in the IC card set in the copying machine (step 2; N). In such a case, the copying machine inquires from the liquid crystal display, display, etc. as to whether or not the password code can be registered in the IC card (step @). When the operator instructs to register a password (Y), the password entered manually using a numeric keypad or the like is registered (step ■). At this time, when registering a PIN code, the copier requires manual input of the PIN code to check the accuracy of the operator, and if this is inappropriate, it is also effective to refuse registration of the PIN code. .

In the embodiments described above, a copying machine using an IC card has been described, but a magnetic card provided with a magnetic stripe may be used instead of an IC card.

In particular, when only storing functional information, even a storage medium with a relatively small capacity, such as a magnetic card, can function satisfactorily. Further, the recording device is not limited to a copying machine, but may be another image processing device such as a facsimile device or a printer, or may be a complex system that utilizes these devices in common. In the latter case, by using a recording medium such as an IC card, a facsimile machine can be used instead of a copying machine to easily make copies with desired copy density and reduction ratio.

Further, in the embodiments described above, the copying work has been mainly explained, but there is an advantage that other works such as maintenance and inspection can also be performed reliably and quickly without being aware of the model.

In the embodiments or modified examples described above, the description was made on the assumption that the recording function information stored in the IC card is directly compared in the base machine 21 and the copying machine function is selected. An identification code may be attached to each combination of function information, and functions may be selected for each card by comparing the identification codes.

Further, in the embodiment, the ROM and RAM in semiconductor format are arranged in the base machine 21, but the magnetic disk and the
It goes without saying that other storage means such as a D (compact disk') ROM may be used. Of course, there are no restrictions on the type or shape of cards that can be set in a copying machine, such as those on which optical information has been written.

Furthermore, in the embodiment, recording function information F is provided. -We decided to write code information consisting of numbers or letters on IC cards in response to FN. Instead, for example, a format as shown in Table 3 below is created on the IC card, and data indicating the presence or absence of these functions for each card (
1" or 0") may be stored as exemplified in the table.

Table 3 "Effects of the Invention" As described above, according to the present invention, recording function information is stored in the card, so even if the card has an extremely small storage capacity, the recording device can be set to the optimal function for the user. can do. Furthermore, since additional control information can be stored on cards with sufficient capacity, existing recording devices can be used for a long period of time without becoming obsolete due to changes or additions to the control information. Furthermore, even if there is some kind of fault in the existing program in the recording device, it can be easily corrected. Furthermore, according to the present invention, by having cards stored on an individual basis, it is possible to limit the scope of copying work for each person, such as restricting personal copying work during breaks, or leakage can be prevented. Furthermore, according to the present invention, by preparing cards for each occupation, it becomes possible to preferentially select the copy magnification, copy density, etc. suited to each occupation, thereby providing detailed services suitable for each type of industry. be able to.

Further, according to the present invention, the functions of the recording device can be expanded or restricted depending on the contents of the card, so the card itself can have value as a product, and the recording device system is easy to sell and easy to use. can be configured. Furthermore, according to the present invention, even one individual can carry a plurality of cards, thereby improving work efficiency.

Also, since the recording function information is set on the card,
This eliminates the need for forgetting numbers or inputting errors, which occurs when an operator sets a password to operate a recording device, and work efficiency is improved in this respect as well.
