In the present embodiment, in the process of inputting a function key, an operation of pressing the function key twice consecutively within a short time (key press → key key up → key press → key up) (double click) Is regarded as an "execution request", and a normal one-time key operation (press-down → pull-up) is previously defined as a "confirmation display operation", whereby the pressing intention identifying means 11 is realized.

Hereinafter, based on the flowchart shown in the drawings,
Processing procedures such as key press interruption processing, key pulling interruption processing, and timer interruption processing after a set time has passed for realizing the present embodiment will be described.

Key Press Interrupt Processing As shown in FIG. 6, in the key press interrupt processing 22a (FIG. 3), the key storage area 23b is displayed while the pressed key is being pressed.
(Step S601), it is discriminated whether or not it is a function key for confirmation display (step S60).
2) If the key is not the confirmation display target, the state flag 23a is set to "up-waiting state 1 (state number = 2)".
Then (step S603), normal key input processing is performed (step S604).

On the other hand, in the case where the pressed key is the key for confirmation display, after confirmation display 42 (FIG. 4) is performed (step S605), the state flag 23a is judged (step S606). When the state is the “pushing waiting state 1 (state number = 1)”, the state flag 23a is set to the “pulling waiting state 2 (state number = 3)” (step S60).
7).

Further, in step S606,
"Pull-up waiting state 1 (state number = 2)", "Pull-up waiting state 2 (state number = 3)", "Pull-up waiting state 3 (state number =
5) ", the state flag 23a is set to" pull-up waiting state 1 (state number = 2) "(step S60).
8).

Further, in step S606,
In the case of “pressing waiting state 2 (state number = 4)”, the setting of the timer interrupt of the timer interrupt work area 23f is canceled (step S609), and the pressed key and the immediately preceding pull-up key storage area 23c are stored. The stored flag is compared (step S610), and if different, the status flag 23
a is set to "up-waiting state 2 (state number = 3)" (step S611). If they are the same, the state flag 23a is set to the "waiting state 3 (state number = 5)" (step S
612), a timer interrupt after a fixed time is set in the timer interrupt work area 23f (step S613).

Interrupt Processing on Key Pull As shown in FIG. 7, in the interrupt processing 22b on key pull, the pulled-up key is stored in the immediately preceding pull-up key storage area 2
3c (step S701), the confirmation display 42 is terminated (step S702), the state flag 23a is determined (step S703), and the state is "waiting for pull-up state 1 (state number = 2)". Judges whether or not there is another key being pressed (step S704), and if there is another key being pressed, the state is left as it is and the processing is ended.
If there is no other key that is being pressed in step S704, the status flag 23a is set to "press wait status 1 (status number = 1)" (step S705).

Further, in the above-mentioned step S703, in the case of "pull-up waiting state 2 (state number = 3)", the state flag 23a is set to "press-down waiting state 2 (state number = 4)" (step S706), and the timer is set. Interrupt work area 23f
Set a timer interrupt after a fixed time to (step S
707).

If the "waiting state 3 (state number = 5)" in step S703, the interrupt setting of the timer interrupt work area 23f is canceled (step S708), and the state flag 23a is set to "wait for pressing down". State 1
(State number = 1) "(step S709), and the function corresponding to the function key is executed (step S710).

Timer Interrupt Processing After Set Time As shown in FIG. 8, timer interrupt processing 2 after set time
2c, the state flag 23a is determined (step S7
51), if the state is the “pushing waiting state 2 (state number = 4)”, the state flag 23a is set to the “pushing waiting state 1 (state number = 1)” (step S752).

In the step S751, if the "waiting state 3 (state number = 5)", the state flag 23
a is set to "up-waiting state 2 (state number = 3)" (step S753).

As described above, prior to executing the function key, it is possible to immediately confirm which key is to be pressed without shifting the line of sight on the keyboard, thereby reducing the burden on the operator and preventing erroneous operation. It can be reduced.

In this embodiment, the case where the function intentional depression of the key is recognized twice is described as the depressing intention identifying device. However, a two-step stroke key having a short stroke and a long stroke by one key depression is used. The intention of the operator may be identified by a stroke length identification device that identifies the length of the stroke.

Further, by measuring the time length of key press, if it is within a certain time, it is identified as "confirmation display", and if it is more than a certain time, it is identified as "execution request". May be identified.

[0036]

As described above, according to the present invention, it is possible to confirm which key is to be pressed on the display screen before executing the process corresponding to the function key, so that the operator's burden or erroneous operation is reduced. Can be reduced.
