JPS63210964A - Registered number setter for image forming device - Google Patents

Abstract

PURPOSE:To speed up a registered number change operation by changing a stepping direction only in the place where a correction is required according to need and resetting the once set registered numbers when said registered numbers are desired to be changed. CONSTITUTION:The registered numbers of the places corresponding to registered number keys 3, 4 are, for example, incremented and the number after 9 is 0 when only the above-mentioned keys are operated in an initial mode (standard state). However, the modes of the respective places are successively changed over to a decrement mode when a mode change-over means is operated. The decrement mode is set with respect to the registered number setting of the 1st place when the means 5 is operated once in the case of, for example, 2 digits. The decrement mode is set with respect to the registered number setting of the 10th place when the means 5 is operated again. The mode returns to the initial mode, i.e., the increment mode is set in both the 1st place and the 2nd place when the means 5 is operated once more again. The operations are thereafter executed in a similar manner.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a number 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 kept as small as possible (to save installation space). According to this, for example, by providing number setting keys corresponding to the 1st and 10th digits, the numbers of 1st and 10th digits 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.

Problems to be Solved by the Invention However, in this conventional example, if you want to change the number of sheets that has been set, you must press the clear key to return to the initial state of 00 or Of, and then reset the number of sheets, or change the number. Operate only the setting key corresponding to the position involved,
The only way to correct it is to increment the number in that position (it takes time to change. In other words, even if you change it using the latter method, which is considered to be relatively quick, for example, 5
If you want to change the number from 6 to 54, press the setting key corresponding to the 1st place 8 times and enter 7.8.9.0, 1 in sequence.

This is because it has to be changed to 2.3.4.

This is undesirable because it causes inefficiency in the operational work involved in resetting the number of entries.

The present invention solves these problems.

Means for Solving the Problems The present invention includes a number display means for displaying the number arranged on the operation section, and an input means for setting the number arranged corresponding to each position of the display means. , a mode switching means for switching the input information mode of the input means, and a control means for sequentially converting each input information mode by operating the mode switching means and returning to the initial mode after the final mode conversion. There is.

For example, there are multiple number setting keys for the number of copies on the operation panel, corresponding to each position, but when these number setting keys are operated in the initial mode (standard state), The number at the position corresponding to the key is incremented, for example, and becomes 0 after 9. However, when the mode switching means is operated, each digit's mode is sequentially switched to the decrement mode. For example, in the case of 2 digits, when the mode switching means is operated once, the digit setting for the 1st digit is changed to the decrement mode. Next, when the mode switching means is operated once again, the mode becomes the decrement mode for setting the 10th position. Furthermore, when the mode switching means is operated once again, the initial mode, that is, the 1st and 10th positions are set to the increment mode. The same manner is repeated below.

Therefore, for example, if you want to change from 56 shown in the prior art example to 54, operate the mode switching means once in the initial mode and then operate the 1st position numeric setting key, and the 1st digit will be 6. 5.4, the desired value of 54 can be obtained in a short time.

In the above case, it is assumed that the initial mode is set to increment mode, but in a copy number setting device whose initial mode is set to decrement mode, when the mode switching means is operated, Switching to increment mode.

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

Figure 1 shows an operation panel (1) installed in an electronic copying machine (not shown).
This operation panel (1) has a display section (2) that displays the number of copies, and a number setting key (3) for the number of copies.
) (4), a mode switching key (
5), a clear key (6), and a print key (7) are provided in the 0 display section (2) in this embodiment, which is a 2-digit display, and each digit is composed of a 7-segment display means. ing. The number setting key (3) is the 1st position, (4
) corresponds to the 10th position, and these keys (3)
(4) can set the number of positions that correspond to each other independently,
Under normal conditions, it functions in the upward direction, that is, in the increment mode. Therefore, under normal conditions, each time these keys are pressed, the number in the corresponding position is incremented by 1,
After 9, it returns to 0. However, for the 10th place, 0 does not light up on the display section (2), and these numeric setting keys (3) (
4) and the mode switching key (5) are connected to the microcomputer (8) as shown in FIG. When these keys are pressed, they turn on so as to connect the power supply (Vcc) and the microcomputer (8)', and when they are released, they automatically return to the state shown and turn off. ing.

In Figure 2, (R'+)'(12*) (Rs) is a resistance, (9) and (10) are drive current control lines for the display section (2), and (11) is a group of segment drive signal lines. It is. Although not shown in FIG. 2, the clear key (6) and print key (7) shown in FIG. It is connected in the same manner as the key (5).

When the clear key (6) is pressed, the 1st and 10th positions mentioned above are cleared and the initial state of 01, for example, is set. In this case as well, the 10th place 0 is not displayed on the display section (2).

When the mode switching key (5) is pressed, the 1st place becomes the decrement mode.0 Next, when the mode switching key (5) is pressed again, the 10th place becomes the decrement mode. When the mode switching key (5) is further pressed, both the 1st and 10th positions return to the initial state of the increment mode. Furthermore, by the second operation of the mode switching key (5), the first position can be held as a decrement, or
The embodiments differ depending on whether to return to the increment mode.

FIGS. 3 and 4 show the operation flow of the microcomputer in the different embodiments.

In FIG. 3, when the electronic copying machine is powered on and the number setting flow starts, it is first determined in step (11) whether the mode switching key has been pressed and turned on. here,
If it is not turned on, it remains in its initial state (19)
, L, and if it is determined that it is turned on, the process proceeds to (I2) and only the first place is switched to the decrement mode. Therefore, when the 1st digit setting key (3) is operated in this state, the 1st digit will increment in the decrement mode, and when the mode switching key (5) is pressed again, (I3 ), it is determined as YES, and the 10th place increment is also set to decrement mode. (13
), if NO, the process goes to END via (I7). When the mode switching key (5) is pressed again, (I
5) becomes YES, and both the 1st and 10th places go into increment mode (therefore, the initial state) (16), (15)
If the judgment is NO, the process proceeds to (I8) and both the 1st and 10th places remain in the decrement mode.

On the other hand, in the embodiment shown in FIG. 4, the operation flow is (14) and (1).
The only difference from the embodiment shown in FIG. 3 is that the first place in B) is the decrement mode.

5 and 6 show the principles of each of the above embodiments in an easy-to-understand manner using signal waveforms. FIG. 5 shows the case of FIG. 3, and FIG. 6 shows the case of FIG. 4. In Figures 5 and 6,
(A) shows the signal waveform obtained by operating the mode switching key (5), (B) shows the first mode, (C)
indicates the 10th mode. In the waveforms (b) and (c), a low level represents an increment mode, and a high level represents a decrement mode. Number setting key (3) The display section (
For example, in the increment mode, the dot displays (12) and (13) are not lit, but in the decrement mode, they are lit. Or, the reverse may be done.

In the above embodiment, for example, 56 is set as the number of copies,
If you want to change this to 54, press the mode switch key (5) once to set the 1st place to decrement mode, then operate the 1st place numeric setting key (3) to change the 1st place from 6 to 5.4. All you have to do is make progress.

If you want to change the previously set numeral 56 to, for example, 58, operate the 1st digit setting key (3) without operating the mode switching key (5) from the initial state.
Progress from 6 to 7.8. Also, if you want to change 56 to 46, operate the mode setting key (5) twice and set 10 to 46.
It is only necessary to switch the position to the decrement mode and then operate the digit setting key (4) at the 10th position.

In the above embodiment, it is assumed that the numeric setting keys (3) and (4) are set to the increment mode in the initial state, and are switched to the decrement mode. The mode may be changed to the increment mode.Also, in the above embodiment, the number of copies is set up to the 10th place, but 10
By displaying the G digit and providing a setting key, it is possible to set the number of sheets 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, if you want to change the numeric value once set when setting the numeric value in the image forming apparatus, it is possible to change the step direction to the extent necessary for correction and reset the setting. , it is expected that the number change operation will be faster.
