Description

[Detailed description of the invention] skin "ice" The present invention relates to a display control method in a copying machine.

The Minobeishihigashi copying machine has various keys such as a group of keys (usually a numeric keypad) for inputting the number of copies and a key (clear/stop key) for canceling the contents entered with the group of keys. The apparatus includes a display section that displays various information such as the number of copies (set number) input using the key group and the status of the copying machine.

By the way, when such a copying machine is delivered to a user, or when a new user joins the machine afterwards, it is necessary to give an explanation (guidance) about how to handle the copying machine.

Conventionally, in such handling explanations, the display contents of the portion of the copying machine's display section that is displayed only when the copying machine is in a special or abnormal state have been explained using photographs in catalogs or the like.

Therefore, it was inconvenient that the user could not confirm the actual display state.

This invention has been made by focusing on the above-mentioned problems, and when explaining how to use a copying machine as described above, it is necessary to explain the display contents that are not always displayed on the display section when they are actually displayed. The purpose is to be able to explain it in detail.

Accordingly, the display control method of a copying machine according to the present invention uses a set of keys for inputting the number of copies and a key for canceling the input contents, which are predetermined among various keys. When a plurality of keys are operated at the same time, the display contents that are not normally displayed on the display section are also brought into the display state.

The present invention will be described in detail below with reference to the accompanying drawings, but first, an example of a copying machine embodying the present invention will be described with reference to FIGS. 1 to 4.

FIG. 1 is a configuration diagram showing an outline of the mechanical parts. It is configured.

The ADF device 1 includes a transport section 4. Paper feed section 5. Original setting section 6
．． and a document discharge section 7.

The copying machine main body 2 has a contact glass 10. Contact glass 1 includes a halogen lamp 11a and a mirror 11b.

3- This copying machine has multiple functions, but in normal copy mode, the ADF device 1 transports originals one by one onto the contact crow 10 using the illuminator 11 and the mirror 12.
a and 12b, and the surface of the photoreceptor drum 14 charged by the charger 15 is exposed to light that is imaged by the through lens 13 using the reflected light to form an electrostatic latent image. A toner image is formed by the developing device 17, is transported from a selected one of the paper feed trays 24 and 25 by the paper feeding conveyance device 26, and is formed into a toner image by the registration roller 27 between the photoreceptor tram 14 and the transfer device. The image is transferred to the copy paper fed at the timing of tm (the feeding path is indicated by a broken line).

Then, the sheet is heated and fixed through the fixing device 28, passed through the reversing section 2, sent to the sorter 3, and discharged onto the sheet discharge tray 34 by the conveyor belt 31 and guide claw 32.

In variable magnification mode, the positions of lens 13 and mirror 12c are moved in accordance with the designated variable magnification ratio to enlarge or reduce the exposed image, but this is the same as in the above-described normal copy 4-mode.

In the double-sided copy mode, the copying of the first side is the same as the above-mentioned normal copy mode until fixing, but after fixing, the copy paper is reversed from front to back by the reversing device 2, and then transferred to the intermediate tray 2.
3. Stack them with the image side up. When copying the second side, copy paper with copies on one side is fed from the intermediate tray 23, the original image is transferred to the other side, and the copy paper is sent to the sorter 3.

In multiple copy mode, the first copy of paper is stacked with the image side down on the intermediate tray without flipping it over.
During the second copying, copy paper with copies made on one side is supplied from the intermediate tray 23, so that another document can be overlapped and copied on the same side.

In the back side discharge mode, the transferred and fixed copy paper is reversed by the reversing device 2, turned over, and sent to the sorter 3, so that the copies discharged onto the paper discharge tray 34 or each bin 35 are stacked in page order. Make it.

In the saw 1-copy mode, the copier body 2 side copies the set number of sheets (within the number of bins of the sorter) of the same original document continuously and sends them to the sorter 3 side one by one. However, by rotating a kite claw (not shown) for each bin 35, copies are sequentially discharged one by one from the first bin.

In stack copy mode, the saw 1 is
~Similar to the copy mode, the number of sheets that have been printed (in this case, there is no limit) is continuously copied and the copy paper is sent to the sorter 3 side one by one, but on the sorter 3 side,
A fixed number of sheets (for example, 50 sheets) are stored in the bin 35 starting from the -H bin 35.

These sorted copies or stacked copies can be made even if all 20 bins of sorter B are not empty, if all the bins 35 in either the bin block 35A or the lower bin block 35B are empty or the bin sheet is If it is detected by the detector 3GA or 36B, only 10 bins of one block can be used, and this case is called dual mote.

In addition, it also has a binding margin adjustment function that allows you to arbitrarily set the left or right binding margin.

Normally, only the necessary parts of each of these display parts 60A, EiOB, and 60C are displayed according to the state of the copying machine (abnormal state 11-) or input, but for example, the clear/stop key 45 and the numeric keypad When multiple predetermined keys, such as the "0" and "1" keys on the 44, are pressed at the same time, all displays will be displayed. When explaining, it is designed to be convenient for explaining the display contents when an abnormality occurs.

Then, when only the clear/stop key 45 or the mode clear key 57 is pressed, or after a certain period of time has elapsed, the auto-reset function automatically returns to the normal display state.

Control of each part in the copying machine of this embodiment is carried out by a microcomputer 20 in the copying machine main body 2, as shown in FIG.
1 and the microcomputer 301 in the sorter 3.

The microcomputer 201 operates a copying section (representatively indicated by reference numeral 202), which is comprised of various parts related to the above-mentioned copying process in the main body 2 of the copying machine, using various keys (representatively indicated by reference numeral 203) shown in FIG. Control according to instructions and
Monitoring of the occurrence of abnormalities, etc. is also carried out, and the various display sections shown in Fig.
4) to perform various displays.

Further, the operation of the ADF device 1 is also controlled in conjunction with the copying section 202.

The microcomputer 301 controls the sorting mechanism section (representatively indicated by reference numeral 302) of the sorter B to perform sorting or stacking operations, and also controls the bin sheet detector 3E.
Input the detection signals of iA and 36B to set all bin use mode or to dual mode (bin block 35A or 35
A decision is made as to whether to use a mode in which only one of B is used.

Data is also exchanged between the microcomputers 201 and 301, and various controls in sort copy mode and stack copy mode are performed in cooperation.

As shown in FIG. 4, these microcomputers 201 and 301 have a central processing unit (cpU) and a read-only memory (for storing operating programs and fixed data).
ROM), random access memory (RAM) for input/output and calculation data storage, and input/output device (I10
) etc. in a well-known manner.

Next, regarding the display control according to the present invention, FIGS.
This will be explained with reference to the figures.

These figures show the microcomputer 201 on the copying machine side.
FIG. 2 is an operational flow diagram of a portion related to display control of the present invention.

First, in the key check routine shown in FIG.
It is checked whether or not the clear/stop key 45 shown in the figure has been pressed, and if it has been pressed, it is checked whether the manual power of that key is valid.

If the clear/stop key is not pressed, or if it is not valid even if pressed, the routine exits without doing anything.

If the clear/stop key is pressed and valid, next check whether "0" and "1" on the numeric keypad 44 are pressed, and if YES, clear the all display flag (predetermined in RAM). Bit) is set to 1'', and if NO, the entire display flag is set to 0''.

That is, if the clear/stop key 45 and the "0" and "1" keys of the tinkey 44 are pressed at the same time and are valid, the full display flag becomes 1'', and if only the clear/stop key 45 is pressed, it is valid. If so, the full display flag becomes "o".

Then, in the display routine shown in FIG. 6, it is checked whether the full display flag is 1" or not. If it is not "L", the normal display is performed, and if it is "L", the display section 60A, EiOB,
Predetermined patterns are displayed on each EiOC.

In this case, the display pattern is, for example, the copy paper remaining amount display 63, 64 and paper size display 65° 6 days is information about the copy paper stored in the upper paper feed tray 24 and the lower paper feed tray 25 at that time. is displayed as is, the set sheet number display 61 and the counted sheet number display 62 both display "99" which is the maximum number that can be displayed, and the fault code display 82 displays "13" which is the maximum number of fault codes. All other displays are set to display state (lit state).

In this way, by displaying (lighting up) all the displays, you can explain each function while pointing at them, especially the forgotten original display 68, copy paper end display 70, jam display 77, etc. This is effective for explaining displays such as the serviceman call display 81 that are only displayed when an abnormality occurs.

The display can be returned to its original state simply by pressing the clear/stop key 45, but it can also be returned using the mode clear key 57, and an auto-reset function can be used to return the display to its original state after a certain period of time has elapsed. It would be good to have it return automatically.

Note that the combination of keys for achieving the full display state is not limited to the combinations in the above embodiments, but may be any combination determined in advance.

In addition, in order to display all the displays at once, for example, the first display section 6
0A, the second display section 60B, the third display section 60C, etc. may be selectively put into the display state.

In this case, in a copying machine that uses a multi-nice play system that displays a plurality of images on one display, the images may be displayed one screen at a time.

As described above with respect to the embodiments, if the display control method according to the present invention is applied to a copying machine, display contents that are not normally displayed on the display section can be displayed at any time. This is extremely convenient for explaining functions at the time of delivery, etc.
