Abstract

PURPOSE:To optionally return or advance the kind of a copying condition to be displayed, by guiding a condition setting with a prescribed order, advancing displaying to that of the next copying condition, and returning it to the previous copying condition again. CONSTITUTION:If a skip key 7 is depressed, a current mode is checked, and a mode is advanced to the mode. For example, when the skip 7 is a density setting mode, a density display LED flashing intermittently is set at a continuous lighting state, and no alteration in density is performed. Next, a magnification setting mode is set. Therefore, the displaying can be advanced to the displaying of the next kind without performing the alteration of the content of the copying condition by depressing the skip key 7. Meanwhile, a reverse reset key 8 is depressed, and when no all-clear timer is operated, the all-clear timer is started. Next, the current mode is checked, and a set to return the mode to a preceding mode is performed.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a copying machine, and more particularly to a copying machine that guides the setting of copying conditions such as density and magnification in a predetermined order.

When copying with a conventional copier, it is necessary to set copying conditions such as density doubling, paper size, number of copies, etc., but those who are not familiar with copying machine operations are confused about the order in which they should proceed with the settings. Sometimes.

Therefore, first display one of each type of copy condition,
It prompts you to set the copying conditions of that type, and when the copying conditions are set, the next type of copying conditions are displayed, making it easy for even those who are unfamiliar with copying machine operations to set the conditions in a predetermined order. A copying machine has been proposed that can perform this function.

Problems with the Prior Art In the conventional copying machine described above, each type of copying condition is displayed in a predetermined order, but the display can be returned to the previous type of copying condition or advanced to the second type of copying condition at will. I couldn't do it.

This is because the display of the types of copy conditions was merely a display for guidance, and in reality, copy conditions could be set and copies could be made regardless of the display. This is because it was thought that there would be no practical problem even if the system was not moved back or forward.

However, those who are not familiar with copying operations tend to think that they cannot perform any operations other than setting the type of copying conditions displayed, so they may be unable to perform any operations other than setting the type of copying conditions that are displayed. In order to make corrections, it is often necessary to start over from the first type of condition settings, or to perform duplicate operations to set the same contents as those that have already been set.
There was a problem that caused a waste of labor.

OBJECT OF THE INVENTION The object of the present invention is to provide a copying machine that sequentially displays each type of copying conditions to guide setting of the conditions in a predetermined order, and to enable the display of the types of copying conditions to be returned or advanced at will. The object of the present invention is to provide a copying machine that can perform the following functions.

Structure of the Invention The copying machine of the present invention displays one of the types of copying conditions such as density 1x, prompts the user to set the contents of that type of copying conditions, and once the settings are made, displays the next type in order. Setting order guiding means for guiding the setting of conditions in a predetermined order, setting order skipping means for advancing to the display of the copying condition next to the copying condition currently displayed, and displaying the copying condition preceding the currently displayed copying condition. The configuration is characterized in that it includes a setting order reversing means for returning the setting order.

By sequentially setting the contents of the types of copying conditions displayed by the action setting order guiding means, the conditions can be set naturally in a predetermined order, making it easy for even a person who is not familiar with copying machines to make the desired copies. It can be done.

When the already set contents do not need to be changed, the display can be advanced to the next copying condition by the setting order skipping means, so it is possible to prevent the same contents from being set repeatedly.

Furthermore, after the next copying condition is displayed, if you notice that there is an error in the setting contents of the previous copying condition, you can return to the display of the previous copying condition by using the setting order reversing means. This also prevents you from having to redo a series of condition settings from the beginning.

Furthermore, by appropriately operating the setting order skipping means and the setting order reversing means, the display of any copying condition can be called up quickly, so the copying machine is configured to accept only the displayed type of condition setting operation. However, it does not cause any operational inconvenience. Therefore, it is possible to configure it in such a way, and if you do so, it will be possible to accidentally touch the operation keys of the copy machine.
It becomes possible to prevent the contents of copy conditions from being changed without knowing.

EXAMPLES Hereinafter, the present invention will be explained in detail based on examples shown in the drawings. Here, FIG. 1 is a plan view of an operation panel of a copying machine according to an embodiment of the present invention, FIG. 2 is a circuit diagram of operation keys, a control circuit, and a display, and FIG. 3 is an operation flowchart of condition setting processing. I like the 4th figure.

FIG. 5 is an operational flowchart of the copy button process, FIG. 5 is an operational flowchart of the reverse process, and FIG. 6 is an operational flowchart of the copy button process. It should be noted that the present invention is not limited to the embodiment shown in the figures.
are the density setting key 211.2b and the magnification setting key 3a~
31, paper cassette setting key 4, and number of sheets setting key 5.

% display 18.

FIG. 2 shows a circuit that controls the operation keys and display LEDs. The status of the operation keys group 9 is read by the CPU 10, and the CPU I O drives the LED group 11 according to the read status of the operation keys group 9. do.

Next, the operation will be explained with reference to FIGS. 3 to 6.

First, the copying machine is powered on, and after predetermined initial processing is performed, a condition setting process shown in FIG. 3 is started.

In this condition setting process, first, the contents of the copying conditions are initialized (Sl). For example, the density is "medium", the magnification is "1x", the paper cassette is "upper", the number of sheets is "1", and the number of sheets is "1".
” is initialized as follows. And the corresponding LED
, lights up the display.

For example, the fourth concentration display LED 12 is lit, the magnification display LED 13b is lit, and the display L of the upper cassette is lit.
ED14. is lit, "1" is lit on the numeric display 17, and the copy button LED 16 is lit.

Next, the density setting mode is entered (S2), which changes the lighting of the density display LED 12 to blinking.

Next, CPU10 performs step 33. S4. S5, S6
is repeated, but this is a loop state that waits for the operation key to be operated.

Step S3 is a process of waiting for any one of the density setting keys 2a+2b, magnification setting keys 31 to 3f, paper cassette setting key 4, and number of sheets setting keys 5a to 5c to be pressed.

Step S4 is a skip process that waits for the skip key 7 to be pressed and is performed when the skip key 7 is pressed. The details will be described later.

Step S5 is a reverse process that waits for the reverse reset key 8 to be pressed and is performed when the reverse reset key 8 is pressed.

The details will be described later.

Step S6 is copy button processing that waits for the copy button 6 to be pressed and is executed when the copy button 6 is pressed. The details will be described later.

Now, if you are unsatisfied with the concentration condition displayed and flashing at ED12, press the concentration setting key 2a or 2t.
Adjust the concentration to the desired level. Then, the corresponding LED is lit (S7).

Next, CPU10 checks the current mode (S8),
Cent next mode. For example, if the current mode is the density setting mode, the magnification setting mode is set (38a).

In the magnification setting mode, the magnification corresponding to the initially set equal magnification is displayed and ED13I blinks.

Then, a loop state occurs in which steps 83 to S6 are repeated.

Since the actual magnification display LED 13I is blinking,
If the operator is not satisfied with this same magnification, the operator uses the magnification setting keys 31I to 3f other than 3h to set the desired magnification.

Then, the settings are changed and the LED corresponding to the newly set magnification is lit, the value of the magnification is displayed on the numeric display 17, and the % display 18 is lit (S
7).

Next, the process moves to step S8, but if the current mode is the magnification setting mode, then the paper size setting mode is set (38%).

In the paper size setting mode, the LED 14a corresponding to the initially set upper cassette flashes, and a loop state is entered in which steps 33 to S6 are repeated again.

Therefore, if you are not satisfied with the upper paper cassette, operate the paper cassette setting key 4 to set the lower paper cassette.
The LED t4b of the lower paper cassette is lit (
S7). - Next, the process moves to step S8, but if the current mode is the paper size setting mode, then the number of sheets setting mode is set (S8c).

In the sheet number setting mode, the initial value "1" is displayed on the number display 17 and blinks.

The % display 18 is turned off. And again the step 8
A loop state occurs in which steps 3 to S6 are repeated.

When the operator wants to make two or more copies, the operator uses the increment key 51.5b or the clear key 5e to change the setting to the desired number of copies. The number display 17 displays the number of sheets (S7), and the process moves to step S8.

In step S8, if the current mode is the number of copies setting mode, a copy button wait mode is set (S8
a).

In copy button wait mode, copy button LED16
is flashing.

Now, in the skip process in step S4, operations as shown in FIG. 4 are performed.

First, it is checked whether the skip key 7 has been pressed (Sll), and if it has not been pressed, nothing is done.

If pressed, the current mode is checked (S12
), proceed to the next mode (312a to S12a
). For example, if you press the skip key 7 in the density setting mode, the blinking density display LED will remain lit (therefore, the density will not be changed), and then the magnification setting mode will be entered (S12 &) Therefore, by pressing the skip key 7, it is possible to proceed to the next type of display without changing the contents of the copying conditions.

What should be noted here is that if the skip key 7 is pressed in the copy button wait mode, the density setting mode is set (S12e).

Therefore, when you have finished setting the - copy conditions and are in the copy button wait mode, press the skip key 7 again.
By pressing , you can be guided through the order of setting copy conditions from the beginning.

Now, in the reverse processing in step S5, the operation as shown in FIG. 5 is performed.

First, it is checked whether or not the reverse reset key 8 has been pressed (S21), and if it has not been pressed, the CPU
The all clear timer built into O is cleared (
S22). The role of this all-clear timer will become clear from the following explanation.

On the other hand, when the reverse reset key 8 is pressed, it is checked whether the all clear timer is operating (S2
3).

If the all-clear timer is not in operation, the all-clear timer is started (S24).

Next, the current mode is checked (S25), and a setting is performed to return to the previous mode. That is, as described above, since the order of density setting - magnification setting - paper size setting, number of sheets setting - copy button waiting is determined, the mode is shifted in the opposite direction.

What should be noted here is that if the reverse reset 8 is pressed in the density setting mode, the mode shifts to the number of sheets setting mode (S25).

By the way, if you keep pressing the reverse reset key 8,
While the all-clear timer starts and is counting time, the reverse process is performed many times, and at this time, the process moves from step S23 to step S26.

In step 326, nothing is done until the all clear timer times up, but when the all clear timer times up, the contents of the copying conditions are initialized (S27) and the density setting mode is set (3
2B).

In other words, if you keep pressing the reverse reset key 8 until the all clear timer time-up time,
All copying conditions are returned to the initial conditions, and the density display LED 12
Those corresponding to the initial setting conditions will be in a blinking state.

Now, in the copy button processing in step S6, operations as shown in FIG. 6 are performed.

First, it is checked whether or not the copy button 6 has been pressed (531). If it has not been pressed, nothing is done, but if it has been pressed, copy processing is performed (332).

Then, the copy button wait mode is set (S33
).

Therefore, even in any of the copy condition setting modes, copying can be performed by pressing the copy button 6, and thereafter the copy button waiting mode is set.

As can be understood from the above explanation, this copying machine is very easy to operate for those who are inexperienced in operating it, as they only need to set the copying conditions sequentially as instructed by the copying machine's blinking LEDs. become. In addition, if you want to set a type of condition that is not currently displayed, you can press the skip key 7 or the reverse reset key 8 to return or advance the display, so even those who are inexperienced with operations can operate it without confusion. can.

As can be understood from Figures 3 to 6, this copying machine actually allows you to change the settings of copying conditions regardless of the display, and also allows you to copy by pressing the copy button. Once you are familiar with the operation, you can operate it just like a normal copying machine.

As another example, in the density setting mode, only the density setting, in the magnification setting mode, only the magnification setting, in the paper size setting mode, only the paper size setting, and in the number of sheets setting mode, only the number of sheets can be set. One example is one that does not accept any other operations. In this case, even if an operation key is touched by mistake, the copy conditions will not be changed to the wrong content, so erroneous copying can be prevented.

Effects of the Invention According to the present invention, one of the types of copying conditions such as density 1x is displayed to prompt the user to set the content of the copying condition of that type, and when the setting is made, the next type is displayed in order. A setting order guiding means for guiding the setting of conditions in a predetermined order, a setting order skipping means for advancing to displaying the copying condition next to the copying condition currently displayed, and a setting order skipping means for guiding the display of the copying condition following the currently displayed copying condition. A copying machine is provided which is characterized in that it is equipped with a setting order reversing means for returning to the display, so that if the conditions are set in order according to the display of the type of copying conditions, the conditions can be set naturally in a predetermined order. You will be able to go there and obtain the desired copy. Since the display can be easily returned to or advanced to any type of copying condition, even if only the desired type of copying condition is to be set, the operation can be performed without confusion.
