Abstract

PURPOSE:To enable setting of each digital place by shifting to another digital place figure switching when a digital value is re-indicated during the switching of a digital value of a cirtain place and when the operation of a setting means is released again. CONSTITUTION:For example, in the case of correcting the current time 12:00 to 12:30 indicated on an indicator 2, a continuous pushing of a setting means 3 leads firstly to choise of the first place of minute for correction by a control circuit 7 and the figure '0' indicated at the moment is memorized in a memory circuit 4. Next, the figure of the first place f minute is switched 0 1 2... in turn. Since '0' is memorized in the memory circuit 4, upon a re-indication of '0' in the first place of minute, a coincidence signal is output from a coincidence judgement circuit 5. And the second place of minute is chosen for correction by the circuit 7, the indicated figure '0' is newly memorized in the circuit 4, and the indicated figure of the second place of minute is switched in turn like the first place, when a hand is left from the means 3, time measurement is started at a timer 6. When the means 3 is pushed, the timer 6 is reset and the setting of each digital place is done for correcting the current time.

Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a digital value setting method.

[Prior Art] For example, in the conventional digital value setting method, when adjusting the time of a digital clock, first operate the mode switch to switch to the time adjustment mode, then operate the correction digit selection switch to select the correction digit. Select , then operate the up/down switch or setting switch on the numeric keypad to switch the correction digit to digital, and when the desired time is displayed, operate the set switch to complete the time correction. It is common to set digital values by operating multiple switches in this way.

[Problem to be Solved] The conventional method described above uses a plurality of switches, so the operation procedure is complicated. Furthermore, the number of parts increases, leading to an increase in the size and cost of the device.

SUMMARY OF THE INVENTION An object of the present invention is to provide a digital value setting method that allows a digital value to be easily set by a simple operation of an operating means.

[Means for Solving the Problems] The present invention sets a digital value of multiple digits for each digit by operating a setting means (in a digital value setting method, a digital value of one digit is set by operating a setting means). When the digital value displayed in the above digit at the time of the start of switching is displayed again, and when the setting means is operated again within a predetermined time after the operation of the setting means is canceled, By shifting to digital value switching of digits other than the above-mentioned digits, the digital values of each digit are set, thereby solving the above-mentioned problem.

[Example] Hereinafter, a case will be described in which the present invention is used to adjust the time of a digital clock.

FIG. 1 shows the internal configuration of a digital watch using the present invention. In the figure, 1 is a clock circuit that measures the current time, 2 is a display unit that displays the current time, and 3 is a device that adjusts the current time. It is a setting means for performing the setting, and in this example, it is a push button. Reference numeral 4 indicates a memory circuit that temporarily stores the display value of a desired digit of the current time displayed on the display unit 2; 5 indicates the value stored in the memory circuit 4 and the current time displayed on the display unit 2; A coincidence determination circuit 6 outputs a coincidence signal when it detects a coincidence with the displayed value of a desired digit, and 6 starts timing when the setting means 3 is released, and starts timing when 5 seconds have been counted. A timer 7 outputs an end signal and is a control circuit that controls current time adjustment operations and the like.

Next, the current time adjustment operation will be explained with reference to the flowchart of FIG. 2 and FIG. 3.

Now, assume that the current time 10:00 displayed on the display unit 2 as shown in FIG. 3(a) is corrected to 12:30.

When the setting means 3 is kept pressed, the control circuit 7 first
The 1 minute digit is selected as the correction digit, and the displayed value at that time is “0”.
'' is stored in the memory circuit 4 (step ■).

Next, as shown in Figure 3 (b) and (C), the displayed value of the 1-minute digit changes sequentially from 0-1-2...
(Step ■).

Next, since "0" is currently stored in the memory circuit 4, when "0" is displayed again in the 1 minute digit, a match signal is output from the match determination circuit 5, and this causes the control circuit 7 to The 10-minute digit is selected as the correction digit, and the displayed value "0" at that time is newly stored in the memory circuit 4 (step 2).

Then, as shown in FIGS. 3(d) and (e), the displayed value in the 10-minute digit is sequentially switched in the same manner as in the case of the 1-minute digit (step 2).

Next, if you release your hand from the setting means 3 when the displayed value of the 10-minute digit becomes "3" for the first time, the control circuit 7 will cause the third
As shown in figure (f), the continuous switching of the 10-minute digit is stopped,
The 1 hour digit starts blinking and the timer 6 starts measuring time (step ■).

Next, when the setting means 3 is pressed before the timer 6 measures 5 seconds, the timer 6 is reset by the control circuit 7.
The blinking display of the 1 o'clock digit is switched to continuous display, and the display value "θ" at that time is newly stored in the memory circuit 4. Then, the displayed value of the 1 o'clock digit is sequentially changed over in the order of 0-1-2, etc. (step ■).

Next, if you let go of the setting means 3 when the displayed value of the 1 hour digit becomes "2" for the first time, the control circuit 7 will cause the 1 hour digit to change continuously as shown in Fig. 3 (h). Then, the 10 o'clock digit starts blinking and the timer 6 starts measuring time (step ■). Since there is no need to correct the 10 o'clock digit, the setting means 3 is set in the state shown in FIG. 3 (h). If you do not operate, when the timer 6 counts 5 seconds, the control circuit 7 will set 12:30 as the current time, all digits will be displayed continuously as shown in Figure 3 (i), and the time will not be corrected. is completed (step ■).

As described above, the current time is corrected by setting a digital value for each digit by operating the setting means 3.

Note that in the above embodiment, the timer 6 outputs a timing end signal when 5 seconds have elapsed, but the timer 6 is not limited to this, and the timing ending time may be set arbitrarily.

Further, the number of corrected digits may be set arbitrarily, such as setting the digital value by combining the 1 o'clock digit and the 10 o'clock digit as an hour digit.

Further, in the above embodiment, the setting means 3 is an up key, but it may be a down key, or both may be provided.

Further, in the above embodiment, the correction digits are sequentially shifted from the one-minute digit side, but the shift order may be set arbitrarily.

[Effects] According to the present invention, digital values can be easily set by simple operation of the setting means.
