Abstract

PURPOSE:To prevent a mis-operation from being performed and to improve operability by prohibiting the acceptance of input while an input prohibition signal is inputted at the time of opening/closing a platen cover or exchanging an original. CONSTITUTION:A control means 3 prohibits the acceptance of data input from a pointing device 1 while the input prohibition signal from an input prohibition signal generating means 2 is inputted. Therefore, since the input by operating a button erroneously or performing area designation in opening/closing the platen cover or in exchanging the original is not accepted, no cancellation or change of a function or change of a designated area, etc., occurs.

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, a facsimile machine, or a printer. When the cover is open or the document is being replaced, input from a pointing device, etc. is not accepted to prevent the selected function or area specification data from being accidentally canceled or changed. It relates to a recording device.

[Conventional technology]

In recent years, along with the spread of copying machines, user demands have diversified.
In response to this diversification, more multi-functional and sophisticated copying machines have been developed and introduced. Relatively new functions provided by copiers include, for example, the ability to arbitrarily set the copy reduction ratio of originals in 1% increments, multi-color copying using two or more types of toner, and single-color copying using a selected color. Functions: Page speed copying function that continuously copies two-page spreads of a bound manuscript one page at a time without moving the manuscript itself; Duplex copying function that automatically copies both sides of the manuscript or both sides of the paper continuously , an editing function that edits and copies multiple documents by combining or deleting them, a job memory function that automatically sets copying conditions by storing copying conditions on an IC card and reading them, and an editor pad. There are many other functions such as the ability to input data by pressing the pen down, etc.

This tendency for devices to become more multi-functional and sophisticated is common not only to copying machines but also to recording devices that record image information such as facsimile machines and printers. In the following, to simplify the explanation, the copying machine will be mainly explained.

[Problem that the invention seeks to solve]

By the way, in a copying machine that uses an editor pad as a pointing device, for example, which is fitted into the platen cover as an opcidin, when inputting a document, the document is placed on the editor pad and a function is selected using the function selection button provided on the panel of the editor pad. Then, figures are entered on the board with a pen down, etc., and after the input is completed, the platen cover is opened, the original is placed on the platen, and the copying operation is performed.

If you accidentally press the button on the editor band when opening and closing the platen cover after entering this data, the selected function may be canceled or the function may be changed.
There were problems such as data entered as "Extract" was changed to "Delete", or the specified area was changed. Furthermore, when creating a single copy from multiple originals, such as in sheet composition, there is a problem in that the button on the editor pad may be pressed by mistake when replacing the originals after inputting one original.

This is often done incorrectly by women's fingers, especially when exchanging documents.

The present invention is intended to solve the above-mentioned problems.The present invention is designed to prevent input from a pointing device, etc., from being accepted while the platen cover is being opened/closed or when replacing a document, so that even if a button is pressed by mistake, the selected function will not be accepted. It is an object of the present invention to provide a recording device that prevents inconveniences such as cancellation or change of data input data or change of designated area input data.

[Means for solving problems]

To this end, the recording device of the present invention is a recording device having an editing function as shown in FIG. A pointing device 1 inputting coordinate data of a point, a human power prohibition signal generating means 2, and data from the pointing device are inputted, and
and a control means 3 to which an input prohibition signal from an input prohibition signal generation means is input, and the control means does not accept input while the input prohibition signal is being input, thereby preventing erroneous button operation. It is possible to prevent inconveniences such as canceling or changing functions, changing specified area input data, etc. even if the area is specified.

(Function) By providing the above-mentioned means, the recording apparatus of the present invention can be used even if a button is accidentally operated or Area I is set while opening/closing the platen cover or replacing a document. Since the input is not accepted, the selected function is not canceled or changed, the specified area is not changed, etc., and operational errors can be prevented and operability can be improved.

〔Example〕

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

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

As shown in this figure, the copying machine that can use an IC card in this embodiment has a base machine 21 that has the most basic configuration, and can be enhanced in functionality by attaching desired additional devices. It has become. Here, the base machine is a device that is equipped with a single-stage supply tray and a tray for manual feeding, and can make copies by manually placing an original onto a platen glass.

The following additional devices can be attached to this base machine.

(1) [c card device 22; The IC card device 22 uses an IC card to store necessary data 9.
This device is used to supply data to the base machine 21, or to write data from the base machine 21 to an IC card. When inputting 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 input work is performed. Note that the IC card device 22 of this embodiment is an IC The card and editor pad are controlled selectively, and it is not possible to use both at the same time to manually manipulate data.

The IC card used in the IC card device 22 of this embodiment has an ISO type interface and has a memory capacity of 2 kilobytes. By using an IC card, complex data can be stored on the card.
It can fully cope with the automation and multifunctionalization of copying machines. 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. You will be able to make your own copy machine.

(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 side. On the other hand, the DADF 24 is an automatic document feeder for double-sided copying. DADF24
Then, the original is transported with one side facing the platen glass and exposed for the first time, and when the original is returned to the tray of the DADF 24 after exposure, its front and back sides are reversed. As a result, when this document is sent out again, the opposite surface to the previously exposed surface 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, copying operations using various combinations such as double-sided originals, double-sided copying, etc. can be automatically performed.

The ADF 23 has basically the same structure as the automatic document feed '4A position 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. It is shaped so that it does not protrude from Machine 21.

(3) Normal platen 25 and platen with editor pad 26; The platen with editor pad 26 has a structure in which a coordinate human power position called an editor pad is placed on the platen for editing the manuscript.0Normal 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 bank 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 used in the copying machine of this embodiment is composed of a liquid crystal display element, and has the advantage of being able to display various messages at any time without increasing the display area. . Which console panel to adopt is determined for each copying machine, taking into consideration 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, ``Multi-stage Sheet Feeding Copying Machine'' in U.S. Pat. No. 61-081016 filed by the present applicant.

(a) Second and third supply trays 31-2, 1-3i 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 copied paper when copying is performed multiple times on one side of the paper or when copying is performed alternately on two sides of the paper.

(c) Second and third supply trays 31-2, 31-3, intermediate tray 338, 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 into a maximum of 10 or 20 distribution destinations.

As described above, in this copying machine system, the Heess 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 make few copies, may use the base machine 21.
In many cases, it is appropriate to purchase a single unit; on the other hand, for customers who make a large number of copies or require complex 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, some of the additional devices are provided with independent CPUs (central processing units) to perform distributed control using a plurality of CPUs. This not only gives Hayabusa the advantage of being able to easily obtain the products that customers want;
The possibility of installing new additional equipment offers customers new possibilities for copying tasks, making the purchase of this copier system very attractive in terms of driving the evolution of office processing. will give.

Incidentally, the system configuration of the copying machine described above can also be explained as a combination of software of the copying machine of this embodiment. In other words, since this copying machine can be equipped with various additional devices, the software can also be designed to have a system configuration compatible with each of these additional devices.

One of the reasons for adopting such a configuration is (+) If the base machine 21 were to prepare operation control programs for all of these additional devices, the memory capacity required for this would be enormous. Depends on what happens. Also,
(ii) If a new additional device is developed in the future or the current additional device is improved, the R in the base machine 21
This is to make it possible to utilize these additional devices without replacing or expanding OM (read-only memory).

For this reason, the base machine 21 has a basic storage area for controlling the basic parts of the copying machine and an additional storage area for storing the program loaded from the IC card together with the functional information of the present invention. Additional storage area includes ADF23
Various programs such as a control program for the DADF 24, a control program for the console panel 28, and the like are stored. Then, when an IC card is set in the tC card device 22 with a predetermined additional device attached to the base machine 21, the program necessary for the copying operation is read out and loaded into the additional storage device. This loaded program works together with the program written to the basic storage area,
Alternatively, the copying operation is controlled by giving priority to this program.

(As described in 2-2-1, in the copying machine of this embodiment, the program stored in the IC card can influence the functions of the copying machine.

Therefore, by changing the program stored in the IC card on a card-by-card basis, it becomes possible to differentiate the use of the copying machine. This will be explained using 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 a base machine 21 shown in FIG.
Card mounting, W22, DADF24, 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 companies or departments may require a DADF 24 or sorter 38, while others may not require any additional equipment.

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

In such a case, IC cards should be prepared according to the usage pattern of each person or each department, and the person or department who wants advanced functions will have to bear more of the basic costs and not have many functions. For example, the owner of the most advanced IC card can use the DADF 24 and sorter by operating the copying machine with the IC card set in the IC card device 22. 38, the 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 do not have a sorting program.
Costs can be saved by using the top bin of the paper as an output tray.

As a second example, a case will be explained in which a copying business operates a self-copying service shop using an IC card.

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 service Li, 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 equipped with a function to display operating instructions as a program, and by setting the IC card, various operating information can be displayed on the console panel 28, so that copying operations can be carried out without error. be able to. 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 copying operations, such as the number of copies and the size of the copying paper used, can be recorded on the IC card, billing for fees becomes easier, and detailed services such as discounts on copying fees for regular customers are also possible. .

As a third example, we will explain a service that uses an IC card that stores a program for a specific user.0For example, in a patent office, when considering patent publications that have been reduced by photolithography, a copy is made that is the same as the original size. 2 because of necessity
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, some users have a demand for using copying machines in special ways. If we la'l- the functions of the copying machine so that it satisfies all of these requirements,
The console panel becomes complicated, and the RO inside the copier
Therefore, by preparing an IC card for each specific user and having the user set the IC card, it is possible to realize a copying machine having 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, the department issuing resident records can now use keys such as a numeric keypad to instruct the type of resident record and fields and items to be deleted on a display such as a liquid crystal display, and then press the start button. By pressing this button, only the desired range of the original will be copied, or only the necessary parts will be edited and recorded.

Figure 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.

Also, although it is not shown in the figure, a manual feed tray 41 is attached to the right side of the device, and a sorter 38 for lO bins is attached to the left side of the device.The manual feed tray 41 is for manual feeding. jtSeveral sheets of paper can be sent 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, 31-3 are arranged, and a 48th and a fifth supply tray 31 are arranged with the 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, the copying machine has a clean design with no protruding ADF (automatic document feeder) or paper feed tray.

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 now possible to do so.

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 portion 54 . This electrostatic latent image is developed by a developing device 59 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 transferred to the feed roll 61-1. Alternatively, the photosensitive drum 63 is sent out, guided by a conveyance roll 69, and passed between the photosensitive drum 51 and the transfer corotron 50.

At this time, the toner image will be transferred onto the copy paper 58. The copy paper 60 after the transfer is transferred to the heat roll 6
6 and a pressure roll 67 to be thermally fixed. Then, it passes between the transport rolls 68, 68 and is discharged onto a discharge tray (not shown).

Nao, in the copying machine of this embodiment, the base machine 21 has a DA
DF24 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 documents stacked in the document storage section of the DADF 24 is set on the upper surface of the platen glass 55. Then, when copying is completed, the original is reset into the original storage unit with the front side reversed, and then the platen glass 5
5 will be sent 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, there is a second supply tray under the first supply tray 31-1.
It is also possible to attach only the supply tray 31-2 and place the copying machine with this configuration on a desk.

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 as follows: For example, Utility Application No. 61-13032, which is disclosed in detail in "Character display device" etc. of No. 61-066170.
No. 0 discloses that a copying machine is provided with a graphic ink display area using a dot pattern, and suggests that various displays can be performed using this graphic ink display area. For example, in a copying machine that can copy parts of a document, move or delete images, etc., the document is placed on the platen using the i! It has been suggested that the image of the target area be read with an image sensor while the device is placed in the same position, and its outline etc. displayed in the graphic display area. There is.

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

Now, a menu display board 71 is arranged on the upper part of the console panel 28, and each panel part 74
The contents of ~79 are displayed in text. Among these, one switch 81 and two display lamps 82 are arranged on the sorter panel 74, so that a sorting mode can be selected when a solenoid 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 of the sorter.

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 (in
) Switch 85 for various other copying forms
and (iv) switch 86 for making double-sided copies.
A display lamp 82 is arranged to indicate whether or not these switches are selected. Here, (i) Editing is a function for inputting data for editing using an editor, etc., and correction/confirmation is a function for displaying input data on the liquid crystal display section (described later) and checking the data. (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, floppy disks, etc. can also be used as nonvolatile memory. In order to reduce the burden on the operator in operating the console panel 28, this copying machine allows settings such as image density and magnification to be preset, and these preset values are stored in non-volatile memory. When the - (in) switch 85 is pressed, text information is displayed on the display panel 79 of this console panel 28, and the message "You can select the desired function from among the other 10 functions" is displayed. .

Examples of the "other" functions here include (a) page snapshot function, (b) border erase function, and (c) gutter function. This is a function that divides a two-page document into two pages and copies them in sequence.
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 the copy.The 0wB margin can be set to a desired length, and the value can be entered using the numeric keypad 80. , can be selected from the numerical values displayed on the display panel 79 at this point.

(1) Finally, double-sided copying is a function that copies copies on both sides of the copy paper. 0 When making double-sided copies, the copy paper 60 on which the first side has been copied is the middle of the copy paper 60 shown in Figure 4. The copy paper 60 that is first stored in the tray 33 is fed out again from this intermediate tray 33, and a copy is made on the side on which the copy was not made. Note that this copying machine performs two copies on one side in the case of monochromatic color copying, which will be explained next. In this case, an arrangement is made such 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.

A display lamp indicating the type (color) of color developer is provided at the top of the monochromatic color 91 tone panel 76 provided below the portion where "Monochrome Color Emphasis°" is displayed on the menu display board 71 in FIG. 87 are arranged.This copying machine allows you to set/set one or more colors of color developer from among four colors such as red and blue, so it is possible to set/set one or more colors of color developer from among four colors such as red and blue. I am trying to turn on the lamp that will be used.

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.

(11) The continuous shooting color composition switch 90 is used when recording one color in a predetermined area of the copy.For example, place the figure to be expressed in color on the right side of the platen glass 55 (see FIG. If you place an original on the left side and make a copy, the image information of the original will be copied in black, and the figure will be drawn on top of it in one color. At this time, if the specified figure is formed by halftone dots, the color figure adjusted to a predetermined density by reproduction of the halftone dots is recorded in a predetermined area of the 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 specified area is copied in one color, and the remaining area is copied in black.

On the other hand, when the (1v) monochrome color switch 91 is selected, the original is copied in one color.

A copy density panel 77 provided below the portion where "copy density" is displayed on the menu display 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 reaching the developing device 59 is extracted by a half mirror or the like, and the potential of the developing bridge in the developing device 59 is set according to the amount of light.

The magnification/paper selection panel 78 provided below the section labeled “Arbitrary magnification” etc. 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 key 101.102
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.
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 lot,
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 magnification is displayed on the magnification display board 104, and in this example, 141.4%, 86.5%, 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.

(a) Manual feed tray display; Select when using the manual feed tray 41 (Fig. 4). Conventional manual feed trays of this type manually feed one sheet at a time, so the operator only has 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 feed 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.

(b) A3 paper display: ゛Select 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) BS 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.

()) BS horizontal paper display; Select when using a tray for feeding B5 size copy paper in a direction perpendicular to the longitudinal direction. (H) Standard outer circumference paper display: When using copy paper of sizes other than the above. Select.

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.
The symbol 111 of this copying machine and the liquid crystal display section 112 are arranged on the 0 display panel 79 where the 0 display panel 79 is arranged.
The pattern 111 is designed to display the selected state of the supply tray, the location where the 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 indicates 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 114i 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, etc.

(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, setting the number of copies, and setting the sorter bin.

(E) Start button 117; This is the key to start the copy operation.

(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.

4J4' Responsibility 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 21 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 CPUs, so for example, an expensive 16-bit CPU
By using an inexpensive 8-bit CPU without using a 8-bit CPU, 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.

In addition, when looking at the printed circuit board on the main body side, by distributing the CPU, there is no need to store unnecessary I10 boards or programs, so it is possible to reduce the cost of the printed circuit board and improve the freedom of placement space. .

This copying machine uses the main CPU in its base machine 21.
The base machine 21 is controlled by a (central processing unit t) 121 and an inter-image lamp CPU 122. Here, the CPU 122 for the 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 for irradiating light onto the photosensitive material 1 to erase a portion of an electrostatic latent image before development. Conventionally, for example, when copying an 85-size original at the same size, light was irradiated onto an area other than the 85-size area on the photoreceptor drum 51 to prevent toner images 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, there are cases where it is 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 static IT layer image. do. 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 publication, but a 4800-port current loop method that achieves the same effect. ing.

In addition, the applicant has developed a CPU 12 for inter-image lamps.
2 is disclosed in detail in ``Image Copying Apparatus'' in Utility Application No. 61-152591 and 1 ``Image Erasing Device for Copying Machine'' in Japanese Patent Application No. 62-023392.

In addition to the above, the copying machine of this embodiment is provided with the following CPtJs, which are connected to communication lines 123 and 124. The main CPU 21 also plays the role of controlling these CPUs and the inter-image lamp CPU 122.

This is a CPU that performs control of 4. If ADF23 (Figure 2) is used instead of DADF24, the ADF
The CPU provided in 23 will be connected to communication lines 123 and 124.

(b) The sorter CPU 126 is a 10-bin sorter 38.
This is the CPU located in the . A dedicated CPU is also arranged in the 20-bin sorter 39. The main CPU 2t knows which sorter 38, 39 is connected and controls sorting accordingly.

(c) Display CPU 127; The display cPU 127 is a CPU used to display various information in kanji on the liquid crystal display unit 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 backlift 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; Tray control CPL 1128 controls the fourth and fifth supply trays 31-4, 31-5, large-capacity tray, and intermediate tray 3 among the trays added to the Heas machine 21.
This is a CPU for controlling 3.

This CPU is installed in the tray cabinet 1. which accommodates each tray. It is located at the rear of the tray, and controls these according to the trays connected.

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.

Is each tray controlled by the tray control CPU 128? 'fI
The l aspect 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.

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

(...) Independent control of the intermediate tray 33.

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

(V) Independent control of large capacity trays.

(E) Card CPLJ 129: When using an RC card 131 that stores function information and additional control information for the copying machine, the card CPU 129 reads the RC card 131 and uses this IC card 131 to specify the coordinates of a document. This is the part that performs reading and writing when used.

Furthermore, although the card CPU 129 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.

It should be noted that Xerox's SIKANDARSIIEIKM explains how to control a copying machine with a control device such as a CPU or a so-called microcomputer.

According to the system configuration of the copying machine of this embodiment, the copy paper 60 can be sent out from a maximum of five types of trays. Therefore, one supply tray has four
If one sensor is installed and digital data is used for this processing, it will be necessary to send 4 bits of digital data from one tray to the main CPU 2t, requiring a total of up to 20 input ports. In addition, the number of connectors and the number of cables constituting the harness increase, which is undesirable from the viewpoint 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.

It is supposed to be done.

(5) 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) Sensitivity The area around the photosensitive drum 51 is shown in FIG. 8 of the dome.

A charge corotron 52 is arranged around the photoreceptor drum 51.
, Interimage lamp 141.4 types of sub-developing devices 59s1 to 59s4, main developer 'AM59M, transfer corotron 50, pig corotron 147,
Pre-clean corotron 148, cleaning device jl
498 and the erase lamp 155 for static elimination are arranged in this order. Here, the first sub-developing device 5931 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 with green toner, and the fourth sub-developing device 59S3 is a developing device that performs development with green toner.
S4 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 when graphic processing (extraction or deletion of a graphic) of a triangular shape is performed using the interimage lamp 141, for example, each light emitting diode unit is processed at the boundary of the processing.

The resulting difference in level will be considerably reduced.

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 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
The main motor 164 starts to be driven when 0.2 seconds have elapsed after the contact of the photoreceptor drum 51. Also main motor 16,1! + (Even when the doctor blade 150 stops, it does not immediately separate from the photoreceptor drum 51, but leaves after 5 seconds have passed. This is because the toner is scattered by the vacuum suction operation, and the copying machine This is a device to prevent situations that could contaminate the inside.

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

(In-color sensor; This is a sensor for determining which color developer is used in each of the sub-developing devices 59S1 to 59S4. Combinations other than the above-mentioned red, blue, green, and brown Even if the sub-developing device Z59s is configured with
The color type can be detected every 9S4. The detection output is input to the dehecolor 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 for stirring and replenishing the toner in the toner box.

The main developing device 59M is for performing black development, and includes a toner sensor and a dispense motor. The increase switch 159 is a switch that the operator presses when he wants to increase the amount of toner. Sub developer 2
When the increase switch 159 is pressed while one of 5931 to 59S4 is selected, the amount of toner is increased for the corresponding sub-developing device. When the main developing device 1t59M 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 5934.
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 device (HVPS) 162 is used to create a parallel electric field inside the main and sub developing devices 59M, 59S1 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. The main motor 164 is used to drive the feed system from the time of alignment of the conveyance timing (registration) of the photosensitive drum 51, the heat roll 66, or the copy paper 60 to the time of ejection.

(5-2) FIG. 9 is a waveform chart showing the switching timing of the main developing device and the sub developing device of this embodiment. This figure shows an example in which the first sub-developing device 59S1 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 L1 as shown in Fig. 5a.
64 is driven. The main motor 164 is continuously driven until time t when the copying operation is completed in both of the two developing devices 59S1 and 59M.

The figure shows the drive timing of the development selection solenoid 161. Dehe selection solenoid 161
is excited until the red copying operation by the first sub-developing device 59S1 is completed.

In this device, the lever is brought into contact with the peripheral surface of a clutch (not shown) by energizing the developer solenoid 161. 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. When one of these protrusions abuts on the first sub-developing device 59S1, this causes the first sub-developing device 59S1 to
is pressed toward the photoreceptor drum 51. At this time, the protruding portions of the remaining cams are located at the farthest positions from the main developing device 59M and other sub-developing devices 59S2 to 59S4, and in this state, the main developing device 59M and other sub-developing devices 59S2 to 59s4 are It is 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 apparatus, 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 is performed at time 1.
Instead of starting immediately, the operation waits for one second. At this time, the above-described cam is connected to the first sub-developing device f59Sl (instead of the main developing device 59M).
Alternatively, other sub-developing devices 59S2 to 5934) are attached to the photosensitive drum 51.

When the copying operation by the first sub-developing device 59S1 is completed, the time t! 5 above for 1 second from
When the two cams move and the protrusion of the monochrome cam is positioned by the lever, the main developing bag 259M is centered with respect to the photosensitive drum 51. After this, monochrome development will be performed.

Note that 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 59S1 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 1 second at this point. It is necessary to set the main developing device 59M relative to the photosensitive drum 51 again after a period of .

”” Nini IIJ Piiromata 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 constituted by a step motor. Position control when the carriage returns to the home position is performed by the registration sensor 172.

The registration sensor 172 is also used for timing the optical system and the conveyance of the copy paper 60.

That is, an actuator for blocking 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 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 image exposure, 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 51, 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.

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 fuser lamps, 82 and 82, are arranged. The sub fuser lamp 182 is shorter than the main fuser lamp 181 (and is disposed at a position slightly biased towards one end of the main fuser lamp 181). The 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 unevenness 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 is used to detect whether the copy paper that has passed between the heat roll 66 and the pressure roll 67 is ejected onto the paper ejection tray without being accidentally caught in both rolls 66 and 67. belongs to.

5-T-3165 is the temperature sensor for fuser lamp 181.182.

5-5 ``Console'' Next, the control relationship of the console will be explained by returning to the 111th EI.

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) for reading and writing the IC card 131 (FIG. 6) and connecting the editor pad 132 (FIG. 6) via the interface holder 193 in the console control unit 191. 22 can be connected. As already explained, this tC card device 22 has a card CPU 129.
(Fig. 6). The console control section 191 is connected to the main board 201. The main cPU 121 described above is mounted on the main board 201.

(5-6 Pilling Counter) Next, the pilling counter used for collecting copy 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 sub-pilling counter 213 is used to count the total number of colors used in each copy when color copies are made.

” Standing two l Next, the power supply relationship will be explained with reference to FIG. 12.

The base machine 21 is connected to a 100V (pol l-) commercial power source. Also 11 for 774 external use
It is also compatible with 5V 60Hz and 220V 50Hz power supplies. Electric power supplied from the outlet 221 reaches the main switch 224 via a 15 ampere circuit breaker 222 and a noise filter 223. The output side of the main switch 224 is supplied as power to an AC driver 226, a fixing control element 227, and a DC power source 228 via an interlock switch 225. Furthermore, DADF24.

61 (FIG. 8) (Y) Main board 201 (FIG. 8, etc.) Unit and back thread Next, the copy paper conveyance system will be explained using FIG. 13.

The first to fifth supply trays 31-1 to 31-5 are each provided with a no-paper sensor 2311, a size sensor 232, and a clutch 233. 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 centimeter for determining the size of the copy paper stored in the tray. Further, the clutch 233 is connected to each feed roll 61.
-1.61-2, . . . are parts for controlling on/off of the drive.

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 23 is a solenoid for the register storage 3 for aligning the leading edges of the copy sheets that have been 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
The 0 manual tray sensor 239, which is a solenoid for switching the drive between the conveyance roller for the copy paper sent out from the manual feed tray 41 and the conveyance roller for the copy paper fed manually from the manual feed tray 41, is connected to the manual feed tray 41.
This is a sensor for detecting the presence or absence of copy paper when multiple sheets of copy paper are being fed. 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. 14.

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, the 0-branch guide 261 passes through the S-shaped conveyance section 258 and is pressed against the branch guide 261 disposed at the intersection of the S-shaped conveyance section 258 and the vertical IJLFa feed section 259, and is thereby released. The original 251 is reversely conveyed and conveyed to the section 262 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. The output of this detection signal causes the document reversing drive roller 264 to rotate in the reverse 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 example of the original being placed in contact with a side positioning guide (not shown). Then, it is conveyed to the correct position on the platen glass 55 by the endless table conveying belt 266. In this way, the copying operation for the first side of the original 251 is performed.

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 accommodated 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 document 251 sent to the horizontal conveyance section 272 is conveyed in the direction opposite to the arrow 267 by the continuous conveyance roller 273, and then transferred to the S-shaped conveyance section 2 by the driving roller 256 and the driven roller 257.
58 is transported. 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 original 251 is fed onto the platen glass 55 using the same transport 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.
The document is sent to the vertical conveyance section 269 and discharged to the document receiving section 271.

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

FIG. 15 shows the appearance of the sorter.

The 10-bin sorter 38 is configured such that the 10 bins 281 can be moved up and down as one unit. The sorter main body 282 includes a drive source (bin motor) for performing this lifting and a l
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. Mode selection for the sorter 38 is performed each time the sorter panel 74 shown in FIG. 5 is operated.

(5-11) Day 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 output to the output tray or sent to the intermediate tray 33 side by the duplex gate solenoid 351 also arranged in the base machine 21. I will be done. A first duplex path sensor 352 is located on the base machine 21 side, and a second duplex path sensor 353 is located on the second supply tray 3 side.
1-2, respectively, and the intermediate tray 3
A paper jam is detected for the copy paper 60 before it reaches the vicinity of 3.

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.The intermediate tray 33 transports the fed copy paper 60 to a desired position according to its size and "falls" into the tray. “Let it happen”
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 skew 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.
A duplex no-paper sensor 362, which is controlled by the PU 128 and conveys the copy paper under the control of the duplex motor 361 (FIG. 8), detects the presence or absence of the copy paper 60 in the intermediate tray 33. It is a sensor. Duplex/
The feed clutch 363 is a mechanism for performing on/off control of a drive source for feeding the 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 impark
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 intermediate tray 33 in Figure N, 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) Tray By the way, a large capacity tray 471 can be set in this copying machine instead of the fourth and fifth supply trays 31-4 and 31-5. Although the configuration is different from that of this embodiment, this will also be briefly explained.

FIG. 17 shows an outline of the circuit configuration of this large capacity tray.

The large-capacity tray 471 can hold 1,000 to 2,000 sheets of copy paper at one time, allowing a large number of copies to be made without interruption.

The large capacity tray 471 is equipped with the following circuit components. The large capacity tray 471 receives AC power from the output side of the noise filter 223 shown in FIG. 8, and also receives DC power from the DCTG source 228 via the main board 201 shown in FIG. is supplied to operate these circuit components.

(H) Feed sensor 479; This is a sensor for detecting a paper jam in the copy paper 6o sent out from the large capacity tray 471. In the following, an editor pad will be used as an example of the pointing device for explanation.

(6-1) Editor Pad The editor pad 132 will be specifically explained with reference to FIGS. 18 and 19.

Of these, FIG. 18 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
Since the DF 24 is mounted on the platen glass 55, the editor pad-equipped platen 26 cannot be mounted on top of the platen glass 55.

In the copying machine shown in FIG. 18, the first supply tray 31-
A platen 26 with an editor pad is attached to the top of a base machine 21 equipped with an editor 1. The square part in the figure is the editor pad 132. Note that this copying machine is equipped with a backlift type console panel. Furthermore, a cabinet 401 in which only the 28th and third supply trays 31-2 and 31-3 are accommodated is arranged below the base machine 21. base machine 2
1 is not equipped with a sorter, but is equipped with a discharge tray 37 for accommodating copy sheets to be discharged.

Please refer to FIG. 2 above for the general configuration of a copying machine. Note that editor pad 1
The reference numeral 32 is very convenient for inputting coordinates, and can be used alone in a copying machine configured as in this embodiment shown in FIG.

In this case, the editor pad 132 may be placed on a desk ring and connected directly to the IC card device 22 (see FIG. 3) using a code, or coordinate data may be written to the IC card 131 and then transferred to the IC card device. It will be used by attaching it to 22.

FIGS. 19, 20, and 21 show the structure of the editor pad. The editor band 132 has three vertical
Rectangular coordinate input pad 4 with a width of 0.07 mm and a width of 432 mm.
It is equipped with 05. An area with a width of 10 mm on the near side of this pad serves as an editor panel 406, which will be described next. Editor band 132 including editor panel 406
As shown in Fig. 21, a first rubber pad on which a resistance line that specifies the position on the It has a structure in which the pressure is applied by an operator's finger or a pointed pen, etc.
, can be sensed as a value on the Y coordinate. A display panel 407 for displaying various information is arranged in front of the editor panel 406. Further, in the inner rear portion of the editor band 132, as shown in FIG. 20, a board 408 consisting of an interface printed wiring board 505 and a pad printed wiring board 507 for processing coordinate data is arranged. The interface printed wiring board 505 and the pad printed wiring board 507 are connected by 20 lines, and the interface printed wiring board 5
05 and the main body printed wiring board are connected by 10 lines for serial communication.

FIG. 22 shows the main parts of the editor spring, lever and display panel explained in FIG. 19. The following buttons are arranged on the editor panel 406.

(a) Special function button 411; This button is used when using special functions.

Here, the color specification button 434 specifies red, the color specification button 435 specifies blue, the zero color specification button 436 specifies green, and the color specification button 437 specifies brown. As already explained, the marking color device of this embodiment can also be equipped with a developing device of a color other than the above. I'll be replacing it with a colored one. Display lamps 438 are arranged in each of the marking-dedicated buttons 431 to 437 described in (W) to (E), and which lamp is selected is displayed.

The coordinate input method is explained with reference to Fig. 23. Fig. 23 (

FIG. 25 is a diagram showing a system configuration that prohibits input from the editor band while the platen cover is open/closed, FIG. 26 is a perspective view of the copying machine with the platen cover open, and FIG. 27 is a diagram showing a time chart. FIG. 28 is a diagram showing an embodiment for detecting the platen half-open state.

8 in FIG. 25, a main body controller 501 having a main CPU 21, and a CPU 129 for an editor pad.
(also used for IC cards) are interconnected and communicate serially, and the main unit has overall control, for example deciding whether or not to accept a function selected from the editor pad side. ing.

The main body controller 501 is the main CPUI 21, RA
Main C consists of M121E and timer 121c.
A signal indicating whether or not the platen cover is in question is inputted to the PU 121 from the platen cover opening/closing detection means 502. The RAM 121B consists of a function code storage section and a coordinate storage section, and stores selected functions and input coordinates.

As the platen cover opening/closing detection means 502, a platen cover interlock switch 504 disposed at a corner of the back surface of the cover as shown in FIG. 26 can be used.

The editor pad side consists of an editor pad CPU 129, a function selection button, and a coordinate input pad, and the functions and coordinate data input from the function selection button and coordinate input band are transmitted to the main CPU 121 through the editor pad CPU 129 by serial communication.

The main CPU 121 monitors the status of each input boat, and if it detects an error in the AD 14, it does not perform processing to prohibit editor band input. This is because in the case of an ADF, there is no need for an editor pad because it is usually not attached or installed separately from the platen. ADF
If the editor pad is not installed and it is possible to use the editor pad manually, first place the document on the editor band, select the function, perform the coordinate manual operation, and complete the settings.Next, remove the document from the editor pad and remove the platen cover. You open it, place the original on the platen, and perform the copying operation. If your finger accidentally touches and presses the function selection button when the platen cover is opened, the function may be changed or canceled. However, in the configuration shown in FIG. 25, when the platen cover is opened, the platen cover opening/closing detection means 502 is activated. For example, when the platen cover interlock switch 504 is used as the platen cover opening/closing detection means, the second
As shown in FIG. 7, an open signal is issued and input from the editor pad side is prohibited.

Since there is a high risk of erroneous operation for a certain period of time after the platen cover is closed, a timer is operated to extend the input prohibited state for a certain period of time to prevent erroneous operation.

As a result, the selected function will not be changed or canceled.

In the above description, an example has been described in which a platen cover interlock switch is used as the platen cover opening/closing detection means, but opening/closing of the platen cover may be detected optically as shown in FIG. 28.

FIG. 28 is a diagram showing an embodiment for detecting the half-open state of the platen cover, and is a side view showing the hinge portion of the platen cover 509. FIG. In this figure, the optical carriage is omitted.

In the figure, a hinge 512 is fixed to a top plate 511 of the copying machine that supports a platen glass 55. The platen cover 509 is attached to the hinge 51 so as to be rotatable in the direction of arrow B around the part indicated by reference numeral 509A.
It is attached to 2.

On the bottom surface of the platen cover 509, the platen cover 50
An arm 513 formed in a circular arc shape centered on the rotation center 509A of No. 9 is fixed. The end of the arm 513 is inserted into the copying machine through an opening 511A formed in the top plate 511.

Further, an opening 513A is formed in the arm 513 so that a sensor 515, which will be described later, can detect the half-open state of the platen cover 509.

The sensor 515 is a photointerrupter in this embodiment, and has a light emitting section 515A and a light receiving section 515B.
The copying machine is arranged such that an arm 513 is inserted between them. When the platen cover 509 is fully open and fully closed, the light emitted from the light emitting section 515A of the sensor 515 is blocked by the γ-memory 513 and does not reach the light receiving section 515B (sensor off). ,
When the platen cover 509 is in a half-open state at position A shown by the broken line, the opening 513 formed in the arm 513 opens.
A moves between the light emitting section 515A and the light receiving section 515B, and the light emitted from the light emitting section 515A reaches the light receiving section 515B (sensor on).

In this way, the half-open state of the platen cover 509 can be detected.

FIG. 29 is a diagram for explaining a processing flow for inhibiting erroneous input, in which (a) shows the processing on the pad side, and (b) shows the processing on the main body side.

To explain the processing on the bad side, Fig. 29 (
In step (b), the function button is constantly scanned and monitored to see if it is pressed, and if a predetermined function is selected, the function code is sent to the main unit (step
), and the reception from the main body side waits for a predetermined period of time after transmitting the reception of the OK code signal, and during this time the reception will wait for the reception of the OK code signal if there is a function display lamp that is already lit. The light goes out, and the function display lamp corresponding to the new function code is turned on (steps ■ to ■). If the code signal is not received even after waiting for the predetermined period of time, the process returns to step ■. .

To explain the processing on the main body side, in Fig. 29 (b),
The pad side monitors whether or not a function code has been received (step (2)), and if it has been received, it is determined whether or not reception is possible (step (2)).

For example, this function will be ignored if the platen cover is open. If the reception is possible, please send the "Acceptance accepted code" to the pad side (Step ■). If there is a function display lamp that is already lit on the console panel of the main unit, it will turn off and the function display lamp selected on the editor pad side will be turned off. The display lamp corresponding to the new function code will be lit (steps ■, ■).

In this way, erroneous human power is prohibited when the platen cover is open.

Figure 30 is a diagram showing the flow when "Extract" has already been selected and the "Delete" button is pressed on the editor pad side, and the control is controlled by "Response/No response". FIG. 5B is a diagram showing the processing flow on the main body side. Control based on <response/no response> means that when there is a new function setting or data input from the editor pad side, whether there is a response from the intangible side that it can be accepted or there is no response for a predetermined period of time. This is a control that determines whether to adopt new function settings or data input, or to return to the previous state without adopting them.

To explain the processing on the editor band side, Figure 30 (a)
, if "Extract" is already selected and the "1 Delete" button is pressed on the editor pad side, the "Delete" function code will be sent to the main unit (steps ■, ■), and after sending, the main unit will The reception waits for a predetermined period of time, for example, 600 m5ec, for the reception of a code-enabled signal (steps ■, ■).
), if no reception is received after 6001w5ec, the function code is returned to "extraction" (step -). When receiving the acceptance code from the main unit, the "extract" lamp is turned off and the "delete" lamp is turned on (step ■).

To explain the processing on the main body side, in Fig. 30 (b),
Determine whether or not the ADF is installed, and if the ADF is not installed, determine whether the platen cover is open (Steps ■, ■). If the platen cover is open, wait until the platen cover is closed (Step ■). When it is closed, start the timer and when the timer reaches the end, determine whether there is any reception from the editor pad side (step ~
■)) Also, if the ADF is included in step ■, the editor pad will not be installed on the platen, but will be placed separately.
You will jump to step ■ regardless of whether the platen is opened or closed. Further, if the platen cover is closed in step (2), it is determined whether or not the timer operation is a time amplifier (step (2)). If there is no reception from the editor pad, return to step ■, and if there is any reception, click
Determine whether the function code is "Delete" or not (Step ■). If it is different, move on to other processing, and if it is "Delete", change the function code on the main unit to "Delete" and accept it to the editor pad. Send code.

Figure 31 is a diagram showing the flow when controlling with ``File operation enabled/disabled''.
is a diagram showing a processing flow on the main body side. In addition, "operation enabled/disabled" control means that when a new function is set or data is input from the editor pad side, an operation enabled or operation prohibited code is sent from the main unit, and if the operation is enabled, a new function is set. This is a control that performs processing based on the received information, and if the operation is prohibited, the pad side is set to the operation prohibited state.

To explain the processing on the editor band side, in Fig. 31 (a), step ■ is when the power is turned on and communication with the main unit has not yet started, and when communication with the 0 main unit, which is in an operation-prohibited state, starts. , Determine whether or not an operation enable code has been received from the main unit (Step ■); If received, set the operation enable state (Step ■); If no operation enable code is received, determine whether an operation prohibition code has been received. (Step ■), and if a prohibition code has been received, the operation is prohibited (Step ■). Also, without receiving an operation enable code or an operation prohibition code, it constantly checks to see if any operation has been performed (step ■), and if it is in an operation-enabled state, it sends information based on the operation to the main unit. ), if the operation is not performed and the operation is not possible, the process returns to step (3).

To explain the processing on the main body side, in Fig. 31 (b), it is determined in step 2 whether or not the ADF is installed, and if the ADF is not installed, it is determined whether the platen cover is open or not. If the platen cover is open, send an operation prohibition code to the editor band (step ■); if the platen cover is not closed, wait until it is closed (step ■); when it is closed, start the timer and time amplifier. Send the permission code to the editor pad side (steps ■~■).

In addition, if the ADF is included in step ■, the editor band is not installed on the platen, but is placed separately, so jump to step ■ regardless of whether the platen is opened or closed, and judge whether it is the first time for the loop and use the editor only once. It will send the operation enable code to the pad and then wait for reception from the editor pad. Further, if the platen cover is closed in step (2), it is determined whether or not the timer operation has timed up (step (2)). If no information is received from the editor pad, the process returns to step (2), and if any information is received from the editor pad, processing is performed in accordance with the received information.

FIG. 32 is a diagram showing a system configuration that prohibits input from the editor pad when replacing a document.

In this embodiment, the end of document replacement is manually input to the editor pad CPU from a document replacement end button 430 (see FIG. 22). The buzzer is for making a sound to confirm the input, and the LE
D is for displaying which function has been selected.0For example, when sheet composition is selected as shown in Fig. 33, it is possible to input up to 5 large areas for the first document, When the settings up to the 5SI area are completed, a message "Ready to copy" and a display indicating that it is the first original are displayed, and the original is replaced at this point. If you accidentally operate the function selection button during this replacement,
Since there is a possibility that unnecessary data may be input by touching the band with a finger, set the next document from the time the first document is manually completed until the replacement is manually completed using the replacement end button 430. Input from the editor pad side is not accepted.

In addition, in Fig. 33, if you want to finish with only area 1, if you press the area setting button without inputting the coordinates for area 2, it will be determined that the manual input of the first page has been completed, and from this point on, you can start from the editor pad. input is prohibited.
