Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention 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 according to the input control information.

(Prior Art) A copying machine capable of reducing the number of keys of an operation section without degrading its function is disclosed in, for example, Japanese Patent Laid-Open No. 60-460. This copying machine has a liquid crystal display on the operation section, a plurality of function keys for selecting the contents to be displayed on the liquid crystal display, and a plurality of preset keys for inputting the contents in the mode selected by the function keys. And are provided.

(Problems to be Solved by the Invention) In the above-mentioned conventional technique, the number of keys is reduced as compared with the copying machine before that, in which one key corresponds to one function, but the input control information is At the same time, it could not be displayed on the liquid crystal display. That is, when confirming all the input control information on the liquid crystal display, after operating the corresponding function key, confirming a part of the input control information, and then repeating the operation of another function key. Had to confirm other control information.
Therefore, the operability at the time of input is poor, and the operation for confirmation is complicated even at the stage when the input is completed.

Therefore, a main object of the present invention is to provide an electronic copying machine in which the number of keys is reduced, the operability at the time of input is not deteriorated, and the input control information can be confirmed at a glance.

(Means for Solving Problems) The present invention relates to a copying machine main body, and a built-in copying machine main body,
Copying means for copying a document, an item display section provided on the copying machine main body for displaying a plurality of control information for controlling the copying means for each item, and an item display section for each item A control information display device having a cursor display portion corresponding to a plurality of cursors, control information input means commonly used for inputting the plurality of display information, and control information input by the input means. And control information storage means for storing standard control information as a standard for a predetermined control item, cursor selection means for selecting a desired one of a plurality of cursors included in the cursor display, and the control A display change for changing the display content of the item display unit corresponding to the selected cursor based on the control information input from the information input means. In the initial state, the control information display unit displays standard control information on the item display section for a control item for which standard control information is stored in the control information storage unit, and displays the standard control information. For control items that are not stored, the item display section is hidden and
It is an electronic copying machine characterized by displaying a cursor on a cursor indicator corresponding to one of the non-displayed display items.

(Operation) In the initial state of the copying machine main body, the control information display unit displays standard control information on the item display section for the control items for which standard control information is stored in the control information storage means, and also performs standard control. For a control item for which no information is stored, the item display portion is made non-display, and the cursor is displayed on the cursor indicator corresponding to one of the non-displayed display items. That is, in the initial state, among the plurality of control items, for example, the control information such as the copy magnification and the number of copies is 100%, and the standard value of 1 sheet is displayed on the item display section, while the original size and the paper size are called. The control item is not displayed, but the cursor of the cursor display corresponding to the document size is displayed, and the operator is requested to input the document size.

When the operator inputs the control information for the displayed or non-displayed control item, the operator operates the cursor selection means. For example, when changing the copy magnification, the cursor on the cursor display unit corresponding to the item display section is selected.

After that, when the control information input means is operated, 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 of the portion displaying the item of the copy magnification of the item display section.

In this way, for example, after inputting the copy magnification, when inputting another item of control information, for example, the item of the number of copies, the cursor in the portion corresponding to the item of the current copy magnification is selected by the cursor selecting means. Move to the part corresponding to the number of copies. After that, in the same manner as described above, the desired number of copies, for example, “10
For example, "10 sheets" is displayed by the display changing means in the portion corresponding to the item of the number of copies on the control information display.

Similarly, when inputting other items of control information, the cursor selection means and the control information input means are used.

When the control information that has already been input is changed after the control information is input, first, the cursor of the cursor display section is moved to the corresponding item display section by the cursor selection means. Then, the control information input means may input the newly changed control information.

When the start key is operated after the input of the control information is completed, the copying process according to the input control information is executed by the copying means.

(Effect of the Invention) According to the present invention, since all the control information input is displayed on the respective item display portions on the control information display, the input control information becomes clear. For this reason,
Compared to a conventional copying machine that cannot display all the input information on a liquid crystal display at the same time, sufficient confirmation can be performed before the copying process is performed, and therefore, the occurrence of miscopy in copying is extremely small.

Further, in the initial state of the main body of the copying machine, the control information display unit displays standard control information on the item display section for the control items for which the standard control information is stored in the control information storage means, and the standard control information is displayed. For the control items that do not store, the item display section is hidden, and the cursor is displayed on the cursor indicator corresponding to one of the hidden display items. Once selected, the operator can quickly enter such control items.

A reset key 112b for releasing all input information set by the key operation of the operation panel 112 is provided on the left side of the.

On the left side of the reset key 112b, a clear key 112c for partially canceling the input information set by the key operation.
Is provided. By operating the clear key 112c, a part of the input to be cleared is determined by the position of the cursor described later. For example, if the set number of copies is 5, the clear key 112c is operated when the cursor is positioned at the portion for displaying the number of copies, and the set number of copies is cleared to 1 copy. Replace After setting other control information, for example, image density, if the cursor is placed and the clear key 112c is operated, the set image density is cleared and returns to the standard image density, as described later.

Zoom keys 112d and 112e for setting the copy magnification are provided on the left side of the clear key 112c. Zoom key 11
2d is operated to increase the setting magnification, and the zoom key
112e is operated to reduce the set magnification. Therefore, for example, if the copy key larger than the desired enlargement ratio is erroneously set by operating the zoom key 112d, the desired copy ratio can be restored by operating the zoom key 112e. These zoom keys 112d and 112e
Works when you do not set the document size. That is, when the original size and the paper size are set, the copy magnification is automatically set. Therefore, even if the zoom keys 112d and 112e are operated, the input of the copy magnification is prohibited.

A change key 112f and cursor keys 112g and 112h are provided on the left side of the zoom key 112e. Zoom key
Control information other than the copy magnification that can be directly set by 112d and 12e is set by operating the cursor keys 112g and 112h and the change key 112f. Cursor key
112g is a key for moving the cursor to be lit in the cursor display section described later to the right.
2h is a key for moving the lighting cursor to the left. That is, the cursor to be turned on is selected by operating the cursor keys 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 the cursor for displaying the image density is lit, the set image density is switched and changed according to the number of operations.

On the display panel 114 on the left side of the operation panel 112, a rectangular liquid crystal display 116 is formed over substantially the entire length of the display panel 114. Under the liquid crystal display 116, cursor display sections 116a to 116j are provided. This cursor display area 116a
In 116j, the lit cursor display portion is selected by the cursor key 112g or 112h. That is,
When the cursor key 112g is operated, the cursor display portion that lights up sequentially moves to the right according to the number of times of operation.

On the contrary, when the cursor key 112h is operated, the cursor display portion that lights up is sequentially moved to the left side according to the number of times of operation.
If the cursor key 112g is operated while the cursor display section 116j is lit up, the cursor display section 11j will light up.
It becomes 2a. Further, when the lit cursor display portion is 116a, operating the cursor key 112h switches the lit cursor display portion to 116j.

The display portion of the liquid crystal display 116 is assigned to the display units 118a to 118h. The display contents of the display units 118a to 118h of the liquid crystal display device 116 shown in FIG. 3 indicate the display contents immediately after the electronic copying machine 10 is powered on, that is, in the initial state. Therefore, new control information is provided by operating the change key 112f after turning on the cursor display portion of the corresponding display portion with the cursor keys 112g or 112h. In the initial state, the cursor display section 116a is lit.

The document size display unit 118a displays which size is the designated document size by using the five types of characters shown in FIG. In the initial state, the cursor display portion 116a is lit, but the document size display portion 118a does not display anything as shown in FIG. So change key 112f
When is operated once, "LD" is displayed on the document size display section 118a, and the document size is designated. When the change key 112f is further operated three times from the time when the display is "LD", the display of the document size display section 118a is sequentially switched, and the third time, as shown in FIG.
"LTR" is displayed on 118a. As described above, the document size is designated by operating the change key 112f after the cursor display portion 116a is turned on. The cursor display section 116a
When is not lit, that is, except in the initial state, operate the cursor keys 112g or 112h to move the cursor display section 116a.
Light up.

The paper size display unit 118b displays the selected transfer paper size in the fourth
It is indicated by the seven types of symbols shown in the figure. Since this electronic copying machine can be loaded with two paper feed cassettes at the same time, it is necessary to select which paper feed cassette is used to print out. Select the paper cassette, that is, specify the paper size, in the same way as when specifying the original size.
After the cursor display portion 116b is turned on by 2h, 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 two paper feed cassettes can be installed at the same time, the paper size stored in one of the paper feed cassettes is displayed on the paper size display unit 118b, and the cursor display unit 116b is turned on. After that, the paper size designation can be switched by operating the check key 112f only once. This reduces the number of times the change key is operated when the paper size is designated.

The magnification display unit 118c displays the copy magnification. In the initial state, "100%" is displayed as shown in FIG. Magnification that can be set with the zoom keys 112d or 112e is 64
% To 141%. Even if you do not operate the zoom key 112d or 112e, if you specify the original size and the paper size, for example, if you set the original size to "LTR" and the paper size to "LG", the copy magnification will be set automatically. As shown in FIG. 4, "127%" is displayed on the magnification display portion 118c. That is, the copy magnification is the zoom key 112d or
112e can be set when the document size is not designated as described above.

The copy number display unit 118d displays the set number of copies. This copying machine can set the number of copies from 1 to 999. In the initial state, the number of copies display section
At 118d, as shown in FIG. 3, "S = 001" is displayed. The hundreds digit is set by operating the cursor keys 112g or 112h to light the cursor display portion 116c and then operating the change key 112f to set a numerical value from 0 to 9. The setting of tens and ones is similar,
After turning on the cursor display portions 116d and 116e, the change key 112f is operated.

The density display section 118e displays which of the seven steps of copy density has been designated. Copy density is set in the cursor display
After lighting 116f, operate change key 112f. In the initial state, the density display section 118e displays "N = 4", which indicates a standard density.

The margin display unit 118f shifts the document image to the right to perform copying, and displays a margin size for providing a margin such as a binding margin at the left end of the paper. Therefore, since it is not necessary to provide a margin, that is, a margin for normal copying, the copying is executed with the display of the margin display section 118f in the initial state of "ma = 0". The size of the margin that can be set is
In this embodiment, there are three stages. To provide a margin on the left edge of the paper, the cursor display portion 116g is turned on and the change key 112f is operated. Then, the size of the set margin is displayed as a numerical value of 1, 2 or 3 in a portion directly above the cursor display portion 116g.

The edging / book display unit 118g displays the edging, that is, the frame erasing mode or the book, that is, the whiteout mode of the book binding, and the size of the frame width when the edging is selected. Edging or book selection is performed by operating the change key 112f after turning on the cursor display portion 116h with the cursor keys 112g or 112h. When edging is selected, "ed = 0" is displayed in the edging / book display portion 118g as shown in FIG. That is, when edging is selected, the frame width also has to be set. When edging is selected and the numerical value immediately above the cursor display portion 116i is 0, edging is not performed and normal copying is performed. Then, when edging is selected, next, in order to set the frame width, the lighting of the currently lit cursor display portion 116h is switched to 116i by the cursor key 112g. Then change key
When 112f is operated once,
1 is displayed as shown in FIG. In this embodiment, the frame width that can be set is three levels.

After illuminating the cursor display section 116h, press the change key 112f
When edging is not selected by, that is, when a book is selected, "book" is displayed on the edging / book display unit 118g. At this time, the cursor display section 116
Even if the change key 112f is operated after the i is turned on, the change key 112f does not work effectively. That is, in this embodiment, when a book is selected, the binding margins of the central portions of the books opened on both sides are outlined, but the width of the centralized portion is constant. Therefore, it is not necessary to operate the change key 112f when the book is selected.

For example, when copying a book document or the like, the two-page continuous shooting display unit 118h displays whether or not the left side and the right side of a book opened to the left and right are disassembled into two sheets and copied. When performing 2-page continuous shooting, the 2-page continuous shooting display section 118h is "2pg = N" in the initial state as shown in FIG. 3, so after the cursor display section 116j is turned on, the change key 112f is pressed. To display “Y” immediately above the cursor display section 116j.

FIG. 5 is a block diagram of the control unit of the copying machine main body. The copier is controlled by a microcomputer system that includes the MPU 120. This microcomputer system has a ROM 122 connected to the MPU 120 for storing a control program and the like, and a temporary storage of data during control by the MPU 120 and various flag areas necessary for control. The RAM 124 and the MPU 120 include an I / O interface 126 for controlling the input / output of the internal device of the main body.

The operation panel 11 is connected to the input port of the I / O interface 126.
Two key matrices 128 are connected, and therefore the data of the key matrix 128, that is, the data output by the operation of the keys 112a to 112h is given to the MPU 120 through the I / O interface 126.

The output port of the I / O interface 126 has a display panel 11
The liquid crystal display 116 of 4 is connected. Therefore, the display contents of the display units 118a to 118h of the liquid crystal display 116 and the lighting positions of the cursor display units 116a to 116j are controlled by the MPU 120 via the I / O interface 126.

Although not shown, a motor, solenoid, etc. controlled by the MPU 120 are also connected to the output port of the I / O interface 126.

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

Next, with reference to FIG. 5B, the operation or operation of the keys 112b to 112h of the operation panel 112 will be described based on the flowcharts shown in FIGS. 6A to 6D. These keys 112b-112h
The operation of is controlled by the interrupt processing of the MPU 120.

In FIG. 6A, the MPU 120 determines whether or not the keys 112b to 112h have been operated in steps S1 to S9.

In the first step S1, the cursor keys 112g and 11
When it is determined that 2h is operated, that is, when the cursor keys 112g and 112h are operated, the MPU 120 is operated from the key matrix 128 through the I / O interface 126.
If it is determined that the data corresponding to the operation of the cursor key 112g or 112h has been given to, the process proceeds to step S11.

In step S11, the operated key is the cursor key 112g.
It is determined whether or not. The operated key is the cursor key
If the MPU 120 determines 112g and the MPU 120, the process proceeds to step S13. If the MPU 120 determines that the operated key is not the cursor key 112g, that is, the cursor key 112h, the process proceeds to step S15.

In step S13, the lighting positions in the cursor display portions 116a to 116j in FIG. 3 are sequentially moved to the right in accordance with the number of times the cursor key 112g is operated. On the contrary, in step S15, the lighting positions in the cursor display portions 116a to 116j are sequentially moved to the left according to the number of times the cursor key 112h is operated.

In step S3, the cursor keys 112g and 112h are used to specify the cursor display area, and then the change key is pressed.
It is determined whether 112f has been operated. This step
In S3, if the cursor display portion 116b is lit,
Next is step S19 in FIG. 6B. In step S19, the selected paper size is displayed on the paper size display unit 118b of the liquid crystal display 116.

In the next step S21, the MPU 120 determines whether or not the change key 112f is subsequently operated. Change key 11
If it is determined that 2f has been operated, the process returns to step S19. Then, in step S19, the display of the paper size display unit 118b is switched accordingly. Since the liquid crystal display 116 shown in FIG. 3 is in the initial state, the paper size display section 118b
Although nothing is displayed on the screen, when the paper size is designated, for example, "LG" is displayed on the paper size display unit 118b as shown in FIG. Therefore, 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 paper size selected in step S19, that is, the data of the selected paper size is further stored in RAM in step S23.
It is stored in 172.

If the cursor display portion 116b is not lit in the first step S1, in step S17 of FIG. 6B, the process proceeds to step S25. In step S25, depending on the number of times the cursor key 112g or 112h is operated, the cursor display unit 11
It is determined by the MPU 120 through the position I / O interface 126 to be turned on from among the cursor display portions 116a to 116j except 6b. Then, the data corresponding to the determined cursor display portion is similarly stored in the RAM 124 in the next step S23.

If the zoom key 112d or 112e is operated in step S5, the process proceeds to step S27. In step S27,
It is determined whether the zoom key 112d is operated. When the zoom key 112d is operated, the process proceeds to step S29.

In step S29, it is determined whether or not the copy magnification is the limit enlargement magnification in the copying machine body 12, for example, 141%. When the magnification displayed on the magnification display unit 118c is 141%, the process proceeds to step S33. The magnification displayed on the magnification display section 118c is 141
If it is smaller than%, that is, if the copy magnification is still expandable, the process proceeds to step S33 via step S31. In step S31, 1% is added to the current magnification displayed on the magnification display unit 118c for display. In step S33, it is determined whether or not the zoom key 112d is continuously pressed. If the button is kept pressed, the process returns to step S29, and steps S29 to S33 are repeated. Therefore, if it is confirmed in step S29 that the maximum enlargement ratio of 141% has already been set, the display of the magnification display unit 118c does not change even if the zoom key 112d is continuously pressed in step S33.
It is prohibited to set the enlargement ratio higher than that.

In step S27, the zoom key operated is 112
If not d, that is, if the operated zoom key is 112e, the process proceeds to step S35. Step S35
Then, it is determined whether or not the magnification displayed on the magnification display unit 118c is a limit reduction magnification, for example, 64%. If the magnification displayed on the magnification display section 118c is 64%,
The process proceeds from step S35 to step S39.

In step S35, if the magnification displayed on the magnification display unit 118c is larger than 64%, that is, if the copy magnification is reducible, step S37 and step S39 are executed.
Proceed to. In step S37, 1% is subtracted from the current magnification displayed on the magnification display unit 118c for display.

Next, in step S39, the MPU 120 determines whether or not the zoom key 112e is being continuously pressed with a finger. If the button is kept pressed, the process returns to step S35 and steps S35 to S39 are repeated. Therefore, in step S39, the maximum enlargement ratio is already 6
If it is confirmed that 4% has been set, even if the zoom key 112e is continuously pressed with the finger in step S39, the display of the magnification display unit 118c does not change, and the setting of the reduction magnification below 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. Step S7
If it is determined that the clear key 112c has been operated, the process proceeds to step S41 in FIG. 6D.

In step S41, for example, when the cursor display section 116a is lit and the display of the document size display section 118a is "LTR", when the clear key 112c is operated, "LTR" of the display of the document size display section 118a is operated. "Is gone. That is, even if the paper size is selected as "LTR" by the operation of the change key 112f, the paper size selection function is initialized when the clear key 112c is operated, and the initial state is returned.

Next, by operating the clear key 112c, and in step S43, the data stored in the RAM 124 is initialized.

Returning to FIG. 6A, in step S9, it is determined whether the reset key 112b has been operated. When the reset key 112b is operated, the process proceeds to step S45. In step S45,
All the data stored in the RAM 124 is cleared, and the initial state is set when the power of the copying machine main body 12 is turned on.

In the next step S47, if any of the cursor display portions 116b to 116j is lit, the lighting is switched to the cursor display portion 116a. Even if the contents shown in FIG. 4 are displayed on the display units 118a to 118h, the liquid crystal display 11 is operated by operating the reset key 112b.
The display content of 6 returns to the initial state shown in FIG.
