Abstract

PURPOSE:To rapidly perform the designation of a mode, at the time of the indication of one mode, by operating the mode designation means during the designation of said mode and other mode designation means in combination. CONSTITUTION:In such a state that a key 1A was pushed down, other mode key, for example, a mode designation key 1C is pushed down. Whereupon, because '0' is inputted to a gate G3, reversal output '1' is sent out to the S-terminal of a flip-flop F31 by the gate G3 to set the flip-flop F31. The output '1' of the Q-terminal of the flip-flop F31 is sent to OR gates G7, G8 and the outputs thereof are further sent out to AND gates G10, G11. The other input of the AND gate G10 is the Q-outputs of flip-flops F12, F22 and, at this time, because the flip-flop F12 is set and the flip-flop F22 has been reset, output '1' is sent out only to MODE1RST of a CPU part 5. Corresponding to this signal, the CPU part 5 performs the setting and display of the mode corresponding to the display part provided to the left end of a block 7A.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a mode designation method for inputting designations such as operation modes and control modes in electronic devices such as electronic typewriters, word processors, and personal computers. It is something.

[Prior Art] Conventional mode designations for electronic devices, for example mode designations for electronic typewriters, include settings for recording line spacing, width of recorded characters, size of recording paper, and the like.

Conventional mode designation methods for such electronic devices have keys for mode designation, and for example, the line spacing can be switched in response to the operation of a designated key for setting the line spacing. The setting is performed cyclically in one direction.

That is, for example, in the case of a mode designation method in which display parts corresponding to each mode are arranged in a horizontal line so that the display part corresponding to the designated mode is displayed, each time a mode designation key is pressed, a predetermined value is displayed. The next mode is set along the direction and the display is moved to the right. Furthermore, when the mode corresponding to the rightmost display section is set and displayed, the mode corresponding to the leftmost display section is set in response to the press of the mode specification key.
I made sure that this display was made.

[Problems to be Solved by the Invention] However, in such a conventional method, when specifying a mode, if the current mode is set to the back in the direction above the desired mode, that is, to the right when looking at the display section. , it is necessary to press the mode specification key once in the mode corresponding to the rightmost display, then return to the mode corresponding to the leftmost display, and then press the mode specification key from there until you reach the desired mode. Therefore, there was a drawback that mode specification was complicated. Further, it often happens that the desired mode is passed through due to an erroneous operation, and in such a case, the complicated process must be performed again.

[Means for Solving the Problems] An object of the present invention is to solve such conventional drawbacks and provide a mode designation method for electronic equipment that allows mode designation with a simple operation. The present invention provides a mode specification method for an electronic device for specifying an operation mode for an electronic device in which the operation mode can be set. and a setting means for sequentially selecting and setting one of the corresponding mode groups in response to the sequential operations of the two mode specifying means, and when one mode specifying means is operated, the other mode specifying means are operated. Sometimes, a predetermined mode is selected and set from among a group of modes corresponding to one mode specifying means being operated.

[Function] That is, according to the present invention, the number of operations of the mode specifying means when specifying a mode is reduced, so operability is excellent, and
Electronic devices with high input processing speed can be realized.

[Example] Hereinafter, the present invention will be described in detail with reference to the drawings.

FIG. 4 shows an example of a mode change processing procedure for CPUbO2 in response to a signal generated by the mode control circuit shown in FIG. 3, and the operation when specifying the mode will be explained using this figure and FIG. 3. First, when the system is powered on, a mode corresponding to the display section at the left end of each of the CPUPbO2- code display blocks 7A to 7c is set, and the mode is displayed.

In addition, all mode specification keys IA to IC are off,
Since "1" is supplied to the R terminal of each flip-flop, all flip-flops are off.

Here, for example, when the mode designation key IA is pressed, the key switch is turned on and the input terminal of the gate G1 is "0".
”, so the inverted output 1'' is the flip-flop F.
It is input to the S terminal of il, and its R terminal is '0
Since it is °°, the flip-flop Fil is set and the Q terminal becomes "i". Also, gate G1
The inverted output of 1'' is sent to the AND gate G4.The other inputs to this gate G4 are the output from the terminal of the flip-flop F22 and the terminal of the flip-flop F32.
Since both have been reset, II II II is sent. For this reason, Antogame 1/G4 has an output of "1".
′′ is sent. Then, the signal is passed through the flip-flop F.
12, and the flip-flop FI2 is set. As a result, CPUPbO2 power terminal MODE
I IN is supplied with °°1” and CPUPbO2−
It is assumed that there is a request for updating code 1, and the procedure shown in FIG. 4 is started.

Here, if the input terminal MODE I R9T is not 1'' (step S1), and if the mode corresponding to the rightmost display section of the display block 7A is not set (step S2), the process advances to step S3. , the contents of the mode storage section 6A are rewritten to shift the display to the right of the mode displayed before key IA was pressed, and to set the newly displayed mode.

At this time, the flip-flop Fit is also set, and the Q terminal output II II is sent to the OR gates G8 and G9, and the OR gate output '1' is sent to the AND gates G11 and G12. Since the flip-flops F22 and F32 are reset, their Q terminal output 1101+ is input to the other input terminals of -1-Gll and G12, so the antgame-hGll and G12 are not opened, and therefore MODE2 There is no output to R9T and MODE 3 R3T.Here, when the operator stops pressing key IA, I output to the R terminals of flip-flops Fit and F12.
I I II is sent out and flip-flops Fil and F12 are reset. Furthermore, if it is desired to shift the mode related to the display block 7A by one more mode, by pressing the mode designation key IA again, the mode is changed in the same manner. Furthermore, if the mode is set to correspond to the display section at the right end of the display block 7A, an affirmative determination is made in step S2 even if the key IA is operated, and the process ends immediately. Sometimes keystrokes are ignored.

Next, the case of setting a mode corresponding to the leftmost display section will be explained. First, press the mode specification key IA,
The mode is shifted as described above. This key I
If you press another mode key, such as the mode designation key IC, while holding down A, ``Opa'' is input to gate G3, so the inverted output by G3 is output.
" is sent to the S terminal of the flip-flop F31, and the flip-flop F31 is set. The output ++ 1 ++ of the Q terminal of this flip-flop F31 is sent to the OR gates G7 and G8, and further, their outputs are sent to the AND gate GIO. and Gll. The other input of this AND gate GIO is the Q output of flip-flops F12 and 'F22, where flip-flop F12 is set and flip-flop F2
2 has been reset, so the MODE of the CPU section 5
Output ゛°1' is sent only to IR3T.

Since an affirmative determination is made in step S1 in response to this signal, CPUf@B5
Set and display the mode corresponding to the leftmost display section of A. Note that the output ``1'' of the inverter gate G3 is input to the analog gate G6, but one of the other input terminals is inputted with the Q output ``o'' of the Noritub flop F12, which is currently in the set state. (Because it's an anime game)
GI3 is not open, so flip-flop F32 is not set.

Although the mode change process using the mode designation key IA has been described above with reference to FIG. 4, the mode change process using the mode designation keys IB and IC can also be performed by a similar process.

In this embodiment, a device having three blocks for specifying a mode has been described, but it goes without saying that the present invention can be easily applied to a device having two, four or more such blocks.

In addition, in the embodiment, the display units were arranged horizontally, but
Of course, this arrangement can be vertical or any other desired arrangement.

Furthermore, in the embodiment, when one mode specifying key is pressed and another mode key is pressed, the mode corresponding to the leftmost display section is set, but for example, the mode is shifted one position to the left. You can also do this.

In addition, although the present invention has been described in the embodiments as applied to an electronic typewriter having a display section on the keyboard, it can also be very effectively applied to word processors and personal computers. Further, regarding the mode of display, for example, if an electronic device has a display device such as a CRT, the display screen thereof can be used.

[Effects of the Invention] As described above, according to the present invention, when one mode is specified, a predetermined mode can be selected by operating the mode specifying means being specified in combination with the other mode specifying means. Since the settings are made, the mode can be specified quickly, and an electronic device with excellent operability and high processing speed can be realized.
