Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to an electronic copying machine, and more particularly to an electronic copying machine that inputs control information from an operation unit and executes a copying process in accordance with the input control information.

(Prior Art) A copying machine that can reduce the number of keys on the operating section without deteriorating its functions is disclosed in Japanese Patent Application Laid-Open No. 60-460, for example.
Disclosed in No. This copier has a liquid crystal display on the operation panel and a screen for selecting the content to be displayed on the liquid crystal display. , IG function keys, and a plurality of preset keys for inputting contents in the mode selected by the function keys.

(Problems to be Solved by the Invention) In the above-mentioned conventional technology, the number of keys has been reduced compared to previous copiers in which one key corresponded to one function, but it is difficult to control inputted control information. It was not possible to display them on the LCD display at the same time. In other words, when checking all the input control information on the LCD display, operate the corresponding function key, confirm some of the input control information, and then repeat the operation of another function key to input it. I had to check other control information.

For this reason, the operability during input was poor, and even after inputting, confirmation operations were complicated.

Therefore, the main object of the present invention is to provide an electronic copying machine that has a reduced number of keys, does not reduce operability during input, and allows inputted control information to be confirmed at a glance.

(Means for Solving the Problems) Simply put, the present invention consists of a copying machine body, a copying means built into the copying machine body for copying an original, and a copying means provided in the copying machine body for copying a document. A control information display device having an item display section for displaying a plurality of pieces of control information for each item, and a cursor display section in which a plurality of cursors are formed corresponding to each item display section; A control information input means commonly used to input control information manually, a cursor selection means for selecting a desired one of a plurality of cursors included in a cursor display, and control information input from the control information input means. Based on G,
The electronic copying machine includes display changing means for changing the display content of an item display section corresponding to a selected cursor.

(Function) When inputting a plurality of pieces of control information, such as copying magnification, number of copies, etc., using the control information input means, the cursor selection means is first operated. Then, the user selects the cursor on the cursor display section that corresponds to the section indicating the copy magnification on the item display section.

Thereafter, when the control information input means is operated one time, the control information of the copy magnification is input to the main body of the copying machine. Then, based on the input control information, the display changing means changes the contents of the copy magnification in the section of the item display section that displays the item of copy magnification.

In this way, for example, after inputting the copy magnification, when inputting other control information items, such as the number of copies, the cursor currently located in the area corresponding to the copy magnification item is moved by the cursor selection means. Move to the part corresponding to the number of copies. Thereafter, in the same manner as described above, the control information input means inputs the desired number of copies, for example "1".
0 copies" etc. manually. Then, in the part corresponding to the item of the number of copies on the control information display, the display changing means will display, for example, 10 copies. When inputting other items of control information, , similarly, by the cursor selection means and the control information input means.

After inputting the control information, if a change occurs in the previously inputted control information, the cursor selection means first moves the cursor on the cursor display section to the corresponding item display section. Thereafter, newly changed control information may be input using the control information input means.

After inputting the control information is completed, for example, when a start key is operated, the copying means executes a copying process according to the inputted control information.

(Effects of the Invention) According to the present invention, all inputted control information is displayed in each item display section of the control information display, so that the inputted control information can be clearly seen at a glance. For this reason,
Compared to conventional copying machines that cannot display all of the input information at the same time on a liquid crystal display, the copying process can be fully confirmed before executing the copying process, so there are very few mistakes in copying.

Furthermore, since multiple pieces of control information can be easily input using the control information input means and the cursor selection means, operability is very good. can be included. Therefore, compared to the operation section of a conventional copying machine which requires a large number of keys, the number of keys required for operation can be significantly reduced.

The above objects, other objects, features and advantages of the present invention will become more apparent from the following detailed description of embodiments with reference to the drawings.

Compression spring 6 for pressing the stacked paper 44 upwards
8 and a branch plate 70 are provided. The spring 68 and the support plate 70 force the uppermost sheets of paper stored in the paper feed cassettes 66 and 74 against the paper feed roller 72. One of the two paper feed rollers 72 rotates to sequentially feed the pressed paper 44 from the paper feed cassette 66 or 74 to the register roller 80 one by one. Note that a manual paper feed tray 78 is provided in association with the upper paper feed roller.

On the downstream side of the developing device 54, a transfer corotron 62 and a separation corotron 64 are integrally provided.

When the paper 44 is supplied from the paper feed cassette 66 or 74, the toner image formed on the photosensitive drum 38 is transferred onto the paper 44 by the transfer corotron 62. During the transfer by the transfer corotron 62, the photosensitive drum 3

A cleaning device 82 is provided along the photosensitive drum 38 on the downstream side of the separation corotron 64 . The cleaning device 82 removes toner remaining on the photosensitive drum 38 without being transferred to the cover 44 . This cleaning device 82 includes a rubber blade 84 for scraping off residual toner on the photosensitive drum 38. The residual toner scraped off by the blade 84 is sent to a waste toner container by a screw conveyor 86.

Further downstream of the cleaning device 82, a static elimination run 188 is provided for removing residual charges on the photosensitive drum 38. Further downstream of the static elimination lamp 88, the above-mentioned charging corotron 48 is arranged.

The paper 44 separated from the photosensitive drum 38 by the separating corotron 64 is sent to a fixing device 90 by a vacuum conveyor 92. The fixing device 90 includes a heating roller 96 having a built-in heater 94 and a pressure roller 98 for pressing the paper against the heating roller 96. Therefore, the toner image transferred onto the paper 44 is heated and pressurized by the two rollers 96 and 98 so that the toner image is transferred onto the paper 44.
will be established. After the fixing, the paper 44 is delivered to the paper ejection tray 10 by a pair of paper ejection rollers 100a and 100b.
2 is discharged on top.

Furthermore, a control box 106 is formed above the fixing device 90 within the main body 12 . Inside the control box 106,
Circuit component 10 for the control system shown in FIG. 5, which will be described later.
8 is stored.

A panel 110 is provided on the upper surface of the front side of the main body of the electronic copying machine. Referring to FIG. 3, the operation panel 112 of the panel 110 is provided with a start key 112a at the right end for instructing the start of the copying process. A set key 112b for canceling all input information set by key operations on the operation panel 112 is provided on the left side of the start key 112a.

A clear key 1120 is provided on the left side of the reset key 112b for partially canceling input information set by key operation. In addition, this clear key 1120
The part of the input that is cleared by manipulating is
It is determined by the position of the cursor, which will be described later. For example, if the set number of copies is 5, if you operate the clear key 112c while placing the cursor on the area where the number of copies is displayed, the set number of copies of 5 will be cleared to 1. Switch. After setting other control information, such as image density, when the cursor is placed and the clear key 1120 is operated, the set image density is cleared and the image density returns to the standard image density, as will be described later.

On the left side of the clear key 1120, zoom keys 112d and 112e are provided for setting the copy magnification.

The zoom key 112d is operated to increase the set magnification, and the zoom key 112e is operated to decrease the set magnification. Therefore, for example, zoom key 112
If a copy magnification larger than the desired enlargement magnification is erroneously set by operating d, the desired copy magnification can be returned to by operating the zoom key 112e.

Note that the zoom keys 112d and 112e are effective only when the original size is not set. In other words, when the original size and paper size are set, the copy magnification is automatically set. From this zoom key 112
Even if d and 112e are operated, input of the copy magnification is prohibited.

On the left side of the zoom key 112e is a change key 112f.
and cursor keys 112g and 112h are provided. Control information other than the copy magnification that can be directly set using the zoom keys 112d and 12e is provided using the cursor key 11.
It is set by operating 2g and 112h and change key 112f. The cursor key 112g is a key for moving a lit cursor on a cursor display section to the right, which will be described later, and the cursor key 112h is a key for moving a lit cursor to the left.

That is, a lit cursor is selected by operating the cursor key 112g or 112h, and the mode on the selected cursor is changed by operating the change key 112f. For example, when the change key 112f is operated after lighting the cursor in the area displaying the image density, the set image density is switched and changed according to the number of operations.

A rectangular liquid crystal display 116 is formed on the display panel 114 on the left side of the operation panel 112 and spans almost the entire length of the display panel 114 . At the bottom of this liquid crystal display 116, cursor display sections 116a to 116j are provided.

In these cursor display sections 116a to 116j, the cursor display section to be lit is selected by the previous cursor key 112g or 112h. That is, when the cursor key 112g is operated, the cursor display section that lights up sequentially moves to the right according to the number of times the cursor key 112g is operated.

Conversely, when the cursor key 112h is operated, the cursor display section that lights up sequentially moves to the left according to the number of times the cursor key 112h is operated. Note that if the cursor key 112g is operated while the cursor display section 116j is lit, the cursor display section 112a will be lit. In addition, when the lit cursor display section is 116a, the cursor key 11
When you operate 2h, the cursor display that lights up is 116j.
Switch to .

The display portion of the liquid crystal display 116 includes display portions 118a to 11
Allocated to 8h. The display contents on the display sections 118a to 118h of the liquid crystal display 116 shown in FIG. 3 are the display contents immediately after the electronic copying machine 10 is powered on, that is, in the initial state.

Therefore, new control information is displayed by turning on the cursor display section of the corresponding display section using the cursor key 112g or 112h, and then operating the change key 112f. Note that in the initial state, the cursor display section 116a
is lit.

The document size display section 118a displays the specified document size using five types of characters shown in FIG. In the initial state, the cursor display section 11
6a is lit, but the document size display section 118a is
As shown in FIG. 3, nothing is displayed. Therefore, when the change key 112r is operated once, "LD" is displayed on the original size display section 118a, which means that the original size has been designated. When the change key 112f is operated three more times from when the display is "LD", the display on the document size display section 118a changes sequentially, and at the third time, as shown in FIG. “LT
R" is displayed. In this way, the document size is specified by operating the change key 112" after lighting the cursor display section 116a.
When 6a is not lit, that is, other than the initial state,
The cursor key 112g or 112h is operated to light up the cursor display section 116a.

The paper size display section 118b displays the selected transfer paper size using seven types of symbols shown in FIG. Note that this electronic copying machine has two paper feed cassettes that can be installed at the same time, so it is necessary to select which paper feed cassette to use for printing. To select the paper feed power, that is, to specify the paper size, use the cursor key 112g in the same way as when specifying the original size.
Alternatively, after turning on the cursor display section 116b using 112h, the change key 112f is operated.

In the embodiment, in the initial state shown in FIG. 3, nothing is displayed on the paper size display section 118b.

However, since only two paper feed power cents can be installed at the same time, the paper size display section 118b is configured to display the paper size stored in one of the paper feed cassettes.
It is also possible to switch the paper size designation by operating the change key 112f only once after the cursor display section 116b lights up. Then,
When specifying paper size, the number of change key operations is reduced.

The magnification display section 118C displays the copy magnification.

In the initial state, "100%" is displayed as shown in FIG. The magnification that can be set using the zoom key 112d or 112e is within the range of 64% to 141%. Note that even if you do not operate the zoom key 112d or 112e, if you specify the original size and paper size, for example, if you set the original size to "LTR" and the paper size to "LG", the copy magnification will be automatically set. Then, as shown in FIG. 4, "127%" is displayed on the magnification display section 118C. That is, as mentioned above, the copy magnification can be set using the zoom mode 112d or 112e.
This occurs when the original size is not specified.

The copy number display section 118d displays the set number of copies. This copying machine allows the number of copies to be set from 1 to 999 copies. In the initial state, the copy number display section 118d displays "5=00" as shown in FIG.
1" is displayed. To set the hundreds place, press the cursor key 1.
12g or 112h to display the cursor display section 116.
After lighting C, set any numerical value from O to 9 by operating the change key 112f.

Similarly, the tens digit and - digit can be set by operating the change key 112f after lighting up the cursor display sections 116d and 116e.

The density display section 118e displays which of seven levels of copy density has been designated. The setting of 4 degrees of copying is performed by turning on the cursor display section 116f and then operating the change key 112f. In the initial state, this concentration display section 118
"N=4" indicating standard concentration is displayed in e.

The margin display section 118f displays the size of the margin for copying by shifting the original image to the right and providing a margin such as a binding margin at the left end of the paper. Therefore, in normal copying, there is no need to provide a margin, that is, a blank space, so the margin display section 118f displays "m a =
Copying is performed with the initial state of ``O'' maintained. In this embodiment, there are three sizes of margins that can be set. To provide a margin at the left edge of the paper, turn on the cursor display section 116g. After that, operate the change key 112r.

The size of the set margin is the cursor display area 1
The number 1, 2, or 3 is displayed directly above 16g.

The etching/book display section 118g shows the etching/noging,
That is, the frame erase mode or the book, that is, the white border mode of the book, and the size of the frame width when edging is selected are displayed. Etching or book selection is performed by turning on the cursor display section 116h using the cursor keys 112g or 112h, and then operating the change key 112f. When edging is selected, "ed=o" is displayed on the edging/book display section 118g as shown in FIG. That is, when you select edging, you must also set the frame width. When etching is selected and the number directly above the cursor display section 1161 is O, no etching is performed and normal copying is performed. So, if you select etching,
Next, in order to set the frame width, press the cursor key 116 to change the currently lit cursor display section 116h to 1161.
Switch by g. After that, change key 112f
When you operate once, the cursor display section 1161 will display
1 is displayed as shown in FIG. Note that in this embodiment, there are three levels of frame width that can be set.

After turning on the cursor display section 116h, when the change key 112f is not used to select "edging", that is, when "book" is selected, "book" is displayed on the editing/book display section 118g. At this time,
Even if you operate the change key 112'' after lighting the cursor display section 1161, the change key 112f does not work effectively.In other words, in this embodiment, when a book is selected, the books opened on both sides The binding margin bone in the center is outlined, but the width of the center is constant.Therefore, when a book is selected, there is no need to operate the change key 112f.

The two-page continuous copying display section 118h displays, when copying a book manuscript, for example, whether to divide the left side and right side of a book opened horizontally into two sheets of paper for copying. When performing two-page continuous shooting, in the initial state, the two-page continuous shooting display section 118h is set to "2pg-N" as shown in FIG. 3, so after lighting the cursor display section 116j, change -I-- Operate 112f to select the cursor display area 1.
Display “Y” directly above 16j.

FIG. 5 is a block diagram of the control section of the main body of the copying machine. The copying machine is controlled by a micro combinator system including MPU 120. This microcomputer system includes a ROM 122 that is connected to this MPU 120 and stores control programs, etc.
A RAM 124 that temporarily stores data during control by 0 and has an area for various flags necessary for control, and an I10 interface 126 that allows the MPU 120 to control input and output of the internal devices of the main body.

The key matrix 128 of the operation panel 112 is connected to the input port of the I10 interface 126, and therefore the data of the key matrix 128, that is, the key 1
The data output by operations 12a to 112h is I
10 interface 126 to MPU 120.

The liquid crystal display 116 of the display panel 114 is connected to the output port of the I10 interface 126. Therefore, the display contents of the display sections 118a to 118h of the liquid crystal display 116 and the lighting positions of the cursor display sections 116a to 116j are controlled by the MPU 12 through the I10 interface 126.
Controlled by 0.

In addition, the output port of the I10 interface 126 has
Although not shown, a motor, solenoid, etc. controlled by the MPU 120 are also connected.

On the other hand, a servo motor controller (LSI) 130 is further connected to the MPU 120, and a DC servo motor 132 for reciprocating scanning of the exposure lamp 28 is connected to an input/output terminal of this controller 130.

Next, referring to FIG. 5B, the key 112b of the operation panel 112 is
The operations or actions from 112h to 112h will be explained. The operations of these keys 112b-112h are controlled by interrupt processing of the MPU 120.

In FIG. 6A, in steps S1 to S9, the key 112b is
The MPU 120 determines whether or not 112h has been operated.

In the first step S1, when it is determined that the cursor keys 112g and 112h have been operated, that is,
When the cursor keys 112g and 112h are operated, the cursor key 11 is transmitted from the key matrix 128 to the MPU 120 through the I10 interface 126.
When it is determined that data corresponding to the operation 2g or 112h has been given, the process advances to step Sll.

In step Sll, the operated key is cursor key 1
It is determined whether it is 12g or not. If the MPU 120 determines that the operated key is the cursor key 112g, the process advances to step S13, and the operated key is the cursor key 112g.
If the MPUI 20 determines that the key is not g, that is, if it is the cursor key 112h, the process advances to step S15.

In step S13, the cursor display sections 116a to 1 in FIG.
The lighting positions in 16j sequentially move to the right. vice versa,
In step S15, the lighting position in the cursor display sections 116a-116j sequentially moves to the left according to the number of times the cursor key 112h is operated.

In step S3, cursor keys 112g and 112
After specifying the cursor display section to be lit by h, it is determined whether the change key 112f has been operated. In this step S3, the cursor display section 116b
If it is lit, the next step is step 519 in FIG. 6B. In step S19, the selected paper size is displayed on the paper size display section 118b of the liquid crystal display 116. In the next step S21, the MPU 120 determines whether the change key 112f has been operated thereafter. If it is determined that the change key 112f has been operated, the process returns to the previous step 319. Then, in step S19,
Accordingly, the display on the paper size display section 118b changes.

Note that since the liquid crystal display 116 shown in FIG. 3 is in its initial state, nothing is displayed on the paper size display section 118b, but when the paper size is specified, as shown in FIG.
For example, "LGl" is displayed on the paper size display section 118b. Then, when the change key 112f is operated, the display of the symbols shown in FIG. 4 is sequentially switched.

If the change key 112f is not operated in step S21, the data of the selected paper size displayed in step S19 is further stored in the RAM 172 in step S23.

In the first step S1, the cursor display section 116b
If not lit, step S17 in FIG. 6B
Now, proceed to step S25. In step S25, the MPU 120 determines, through the I10 interface 126, the position to be lit among the cursor display sections 116a to 116j, excluding the cursor display section 116b, according to the number of times the cursor key 112g or 112h has been operated. Then, the data corresponding to the determined cursor display area is stored in the RAM 124 in the next step S23.
is stored in

In step S5, the zoom key 112d or 11
If 2e is operated, the process proceeds to step S27. In step S27, it is determined whether the operated zoom key is 112d.

If the zoom key 112d is operated, step 329
Proceed to.

In step S29, it is determined whether the copying magnification is the limit magnification of the copying machine body 12, for example 141%.

If the magnification displayed on the magnification display section 118c is 141%, the process advances to step S33. If the magnification displayed on the magnification display section 118c is smaller than 141%, that is, if it is still a copy magnification that can be enlarged, step S3
1 and then proceeds to step S33. In step S31,
This is displayed by adding 1% to the current magnification displayed on the magnification display section 118c. In step S33, the zoom key 11
It is determined whether 2d continues to be pressed. If it continues to be pressed, the process returns to step S29 and step 329
~Repeat step S33. Therefore, step S
When it is confirmed in step S33 that the maximum magnification of 141% has already been set, the zoom key 11 is pressed in step S33.
Even if the user continues to press 2d, the display on the magnification display 118c does not change, and further setting of the magnification is prohibited.

In step S27, if the operated zoom key is not 112d, that is, if the operated zoom key is 112e, the process proceeds to step S35. In step S335, the magnification displayed on the magnification display section 118c is the limit. It is determined whether the reduction magnification is, for example, 64%. If the magnification displayed on the magnification display section 118c is 64%, the process advances from step S35 to step S39.

In step 335, if the magnification displayed on the magnification display section 118c is greater than 64%, that is, if it is a copy magnification that can be reduced, the process advances to step S39 via step S37. In step S37, 1% is subtracted from the current magnification displayed on the magnification display section 118C and displayed.

Next, in step 339, the MPU 12O determines whether the zoom key 112e continues to be pressed by a finger. If it continues to be pressed, the process returns to step S35 and steps 835 to S39 are repeated. Therefore, step 3
When it is confirmed in step S39 that the minimum magnification of 64% has already been set, in step S39, press the zoom key 1 with your finger.
Even if 12e is kept pressed, the display on the magnification display section 118c does not change, and setting a reduction magnification lower than that is prohibited.

Next, in step S7 of FIG. 6A, it is determined whether the clear key 112c shown in FIG. 3 has been operated. If it is determined in step S7 that the clear key 1120 has been operated, the process advances to step 341 in FIG. 6D.

In step S41, for example, the cursor display section 116a
is lit, and the display on the document size display section 118a is “
LTR", when the clear key 112c is operated, the "LTR" displayed on the document size display section 118a disappears. In other words, the paper size was selected to be "LTR" by operating the change key 112f. Even in this case, when the clear key 112G is operated, the paper size selection function is initialized and returns to the initial state.

Next, by operating the clear key 1120,
Furthermore, in step S43, the data stored in the RAM 124 is initialized.

Returning to FIG. 6A, in step S9, the reset key 1
12b is operated. When the reset key 112b is operated, the process advances to step S45. In step S45, all data stored in the RAM 124 is cleared, and the copying machine main body 12 is in the initial state when the power is turned on.

In the next step 347, the cursor display sections 116b to 1
16j is lit, the lighting is switched to the cursor display section 116a. Then, the display section 118a
Even if the content shown in FIG. 4 is displayed between 118h and 118h, the display content on the liquid crystal display 116 returns to the initial state shown in FIG. 3 by operating the reset key 112b.
