Abstract

PURPOSE:To permit an extremely convenient mode setting operation by clearing only the desired function mode and holding the other function modes as they are when an operation key for the desired function mode and a clear key are simultaneously operated. CONSTITUTION:The respective places are respectively the function modes in the case of registering numbers to set the number of copies of, for example, an electronic copying machine. All the places are cleared and are returned to the initial state when only the clear key 7 is operated. Only the places corresponding to the operation keys 18, 19 of the respective places are reset to the initial state and the remaining places do not change when the keys 18, 19 for the respective places are operated together with the clear key 7. Resetting of the registered numbers from the initial state for only the desired places is, therefore, possible. The initial state is obtd. only with the desired function modes if the operation keys 12, 13, 16 corresponding to the function modes 2, 3 desired to be reset to the initial state among the function modes existing in plurality are operated together with the clear key 7 when only the above- mentioned function modes are desired to be cleared without being limited to the case of the mode setting with respect to the above-mentioned registered.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a mode setting device for an image forming apparatus such as a copying machine, facsimile machine, or printer.

Conventional electronic copying machines have been proposed in Japanese Patent Application Laid-Open No. 151656/1983, in which the number of keys for setting the number of copies is reduced as much as possible to save installation space. . According to this, for example, by providing number setting keys corresponding to the 1st and 10th places,
The number of sheets in the 0th place can be set independently. The value of each digit is incremented by 1 each time the setting key is operated, and returns to 0 after 9. When the clear key is operated, both the 1st and 10th positions can be returned to their initial states at the same time.

Problems to be Solved by the Invention As mentioned above, in electronic copying machines, the number of copies is set to 1.
If the digit and 10th positions are set as function modes, both function modes will be cleared by operating the clear key.In addition to the above-mentioned numbers, other function modes, such as paper feeding mode and density mode, will also be cleared. Operation of the clear key uniformly returns to the initial state. Therefore,
In practice, even if you want to clear only a specific mode and leave other modes as they are, there is a problem in that it is not possible. Therefore, in the conventional number setting, if you want to change the number that has been set, you must press the clear key to return to the initial state of 00 or 01, and then reset the number of sheets, or you must respond to the position that is involved in the change. The only way to correct the setting is to operate only the setting key to increment the number at that position, and it takes time to change it. In other words, even if you use the latter method, which is considered to be relatively quick, if you want to change the number from 56 to 54, for example, press the setting key corresponding to the 1st place 8 times and press 7 in sequence.
．． This is because it has to be changed to 8.9.0.1.2.3.4. This is undesirable because it causes inefficiency in the operational work involved in resetting the number of entries.

Means for Solving Problems The present invention provides function mode setting keys for setting various functions in an image forming apparatus, and a clear key for returning the state set by the setting key to the initial state. In the mode setting device provided, when only the clear key is operated, at least two or more function modes are returned to the initial state, and when either the clear key and the operation key are operated at the same time, the operation key is A control means is provided for returning only the corresponding function mode to its initial state.

Function For example, in the case of setting the number of sheets on an electronic copying machine, each position is in its own function mode, and when only the clear key is operated, all positions are cleared and return to the initial state. When is operated, only the digit corresponding to that operation key returns to the initial state, and the remaining digits remain unchanged. Therefore, the digits can be reset from the initial state only for the desired digit. For example, 0 If you want to change 56 shown in the conventional example to 54, return only the 1st position to the initial state and set the 1st position to O, then release the clear key and operate only the 1st position function key, sequentially. , l, 2.3.4
I'm going to change it.

In addition, not only in the case of mode settings related to numeric values, but if you want to clear only the function mode that exists among multiple function modes that you want to return to the initial state, use the above-mentioned clear key and the operation corresponding to that function mode. By operating the keys, the initial state can be obtained only for the desired function mode. In this case as well, when only the clear key is operated, at least two or more function modes are cleared.

Example Embodiments of the present invention will be described below with reference to the drawings.

In Fig. 1, (1) is an operation panel (not shown) provided on an electronic copying machine, and this operation panel (1) includes, from the left, a density mode section (2) for setting the density of the copy, a paper feed Mode section (3)
, interrupt mode section (4), number of copies display section (5), number setting mode section for number of copies (6), clear key (7),
and a print key (8). The density mode section (2) is provided with fixed numbers 1 to 5 for displaying the density in five stages and the corresponding LED (9), as well as an indicator section (10) that indicates the direction of the density. (11) is arranged. Then, a key (12) to set the density mode to the density 1 side and a key (13) to set the density mode to the density 5 side.
is available. The initial state of this density mode section (2) is set to the normal density 3 position.

Next, in the paper feeding mode section (3), fixed displays such as "Bypass" and "Automatic feeding" are displayed, as well as indicators (14) to instruct them.
(15) is provided, and each time the paper feeding mode setting key (16) is pressed, "automatic paper feeding" and "bypass" are set alternately. Note that the indicators (14) and (15) are composed of LEDs. The initial state of the paper feeding mode section (3) is "automatic paper feeding".

The interrupt mode section (4) is only provided with its setting key (17). The copy number display section (5) is a two-digit display in this example, and both the 1st and 10th places are 7.
Consists of segment indicators.

In the numeric setting section (6), a numeric setting key (18) for the 1st position and a numeric setting key (19) for the 10th position are arranged side by side, and each time these keys are pressed, the numeric value of the corresponding position is changed. is incremented by 1, and returns to 0 after 9. However, for the 10th place, O does not light up on the display section (5), and these numeric setting keys (1B) (19) and clear key (7) are not lit on the micro combiator (20) as shown in Figure 2. )It is connected to the. When these keys are pressed, they turn on so as to connect the power supply (VcC) and the microcomputer (20), and when they are released, they automatically return to the state shown and turn off. . In Figure 2, (R
1) (*t) (R3) is a resistance, (21) (
22) is the drive current control line of the display section (5), (23)
is a group of segment drive signal lines.

Setting keys for other function modes shown in FIG. 1 are also not shown in FIG.
0) in the same manner as the numeric setting key <18) (19) and the clear key (7).

When only the clear key (7) is pressed, all the above-mentioned functional modes are cleared and the initial state in each mode is set. At that time, the 1st mode and 10th mode in the numeric setting mode section (6) are also cleared, and 00
Or return to the initial state of 01.

However, when any of the numeric setting keys (1B) (19) and the clear key (7) are operated at the same time,
Only the position corresponding to the operated setting key becomes the initial state.

Next, the operation flow of the micro combinator (20) will be explained with reference to FIGS. 3 and 4.

First, in FIG. 3, when the power is turned on to the electronic copying machine and the number setting operation flow starts, first, the presence or absence of a clear signal is determined in (11). If no clear signal is input by the clear key (7), go to END. If a clear signal is input, go to (I2), where there is an increment signal for the 1st place by the 1st place numeric setting key (18). Check if it is, and if not, go to the next (I3) and do the same 1
It is determined whether or not there is an increment signal for the 10th position by the 0th position numeric setting key (19).

22, but if there is no increment signal, the 1st and 1st
Clear the 0th place display to the initial state. In this case, the initial state may be either Of or OO, however,
In the initial state, the 10th place value is not displayed in any case, and therefore only the 1st place value 0 or l is displayed.

If it is determined that there is an increment signal for the 1st place in the previous step (2), proceed to (I6) and make the display contents of the 1st place the initial state. In this case, the initial state is 0 or ! It must be set to 0 instead of 0, otherwise, for example, 10 or 20
This is because it is inconvenient when setting the number of sheets, etc. However, in the case of a decrement type instead of an increment type, the initial state of the first place may be set to 1.

Next, in the previous step (I3), if it is determined that there is an increment signal for the 10th place, the process proceeds to (I5) and the display contents for the 10th place are cleared. In this case, the initial state of the 10th place after clearing is 0, but the display does not light up.
14), (15), and (16) reach END when these operations are completed. In Figure 3, (11)
In the case where there is no clear signal, a flow is added in which, without going directly to END, the presence or absence of increment signals for the 1st and 10th positions is determined and the numbers are set.

In Figure 3 above, the presence or absence of the clear key is first determined, and then the presence or absence of the 1st and 10th increment signals is determined sequentially, but the order may be changed. This is an example of a flow in which the operating state of the numeric setting key in the 1st position is first determined, and then the operating state of the numeric setting key or the clear key in the 10th position is determined.

Figure 4 shows the 1st position numeric setting key (18) and the clear key (
7) is operated at the same time, QI-Q! → Proceed to Q1, 10th position numeric setting key (19) and clear key (7)
When is operated, it advances as Q, →Qs→Q, →Q, and when only the clear key (7) is operated, it advances as QI→Q
s-Q, →Q8. Take the flow of

Furthermore, Q if only the 1st position numeric setting key (18) is used.

→Q8→Q, If only the 10th position numeric setting key (19) is operated, the flow will be Q1→Qs-Q-→Q.
In FIGS. 3 and 4, after END, the process returns to 5TART and repeats the same flow, and this flow continues as long as the electronic copying machine is powered on.

As mentioned above, when either the numeric setting keys (18) or (19) and the clear key (7) are operated at the same time, only the digit corresponding to the operated numeric setting key is cleared. However, "simultaneously" in this case does not mean physically at the same time; it is sufficient that one is operated and the other is operated within a predetermined time set by a timer in the microcomputer (20). That is, as shown in FIG. 5 (a), if the 1st or 10th increment key is pressed within a certain period of time (1) from the time when the input of the clear key (7) starts, the It turns out that.

Therefore, each of the cases in (b), (c), and (d) in FIG. 5 is considered to be the same as the clear key. Note that the certain time period (1) is, for example, 5 to 15 asec. Similarly, if the increment signal is input using the 1st or 10th position numeric setting key and the clear signal is input later, (1) If there is a time when both are at high level within the time, it is considered to be simultaneous. Become. The above also applies to the end of the operation (therefore, at the falling edge of the waveform in FIG. 5), and after setting a predetermined time, it is determined whether or not the switches are turned off at the same time.

For example, if the 1st or 10th increment input falls slightly earlier than the clear key input, and as a result, there is only a small amount of clear key input left, it will be determined that only the clear key was pressed, and all inputs will be ignored. This is to avoid clearing the functional mode of .

In the flowcharts of FIGS. 3 and 4, only the setting mode related to the number of copies was explained, but in FIG. 1, the clear key (7) and other mode setting keys (12) are used.
, (13) or (16) at the same time to clear only the function mode corresponding to the operated mode setting key.

Although the present invention has been described above with reference to examples, the present invention is not limited thereto (various changes and modifications can be made without departing from the gist of the invention described in the claims). It is possible.

For example, although the above embodiment is based on the assumption that the 1st and 10th places are both incremented, the present invention can be similarly applied to a type that is decremented. Further, in the above embodiment, the case where the number of copies is set up to the 10th place is shown, but by providing a display and a setting key for the 100th place, it is possible to set the number of copies in three digits. In the same way, it is possible to expand to even more orders of magnitude.

Effects of the Invention According to the present invention, in an image forming apparatus that has a plurality of function modes, when only the clear key is operated, at least two or more device modes are cleared as in the past, but the desired function mode is cleared. When the operation key and the clear key are operated at the same time, only the desired function mode is cleared and the other function modes are kept as they are, which is extremely convenient for mode setting operations. In particular, when you want to change the number of copies that has been set once when setting the number of copies on an electronic copying machine, for example, you can clear only the parts that need to be corrected and set them again, which speeds up the operation to change the number of copies. You can expect it.
