Abstract

PURPOSE:To allow the approximate second time to be judged by providing the time for stopping flickering within 60 seconds in at least one of the plural segment points provided in such a manner that these points can be flickered. CONSTITUTION:Colon marks 4 indicating the segment is disposed between an hour display 2 and minute display 3 of this clock 1. The marks 4 are respectively provided in such a manner that the marks can be flickered. The time to stop the flickering of at least one segment point within 60 seconds is provided. Namely, the pulses of an oscillation circuit 5 to use a crystal resonator as the standard time are frequency divided 6 and the time is displayed by the frequency dividing signals in a digital display part 7. The marks 4 are flickered in a colon flickering part 8. The dots of the marks 4 are flickered by a colon flickering device 13 according to the time to integrate the frequency dividing signals in a timer circuit 12 of this flickering part 8. The approximate second time at the point of this time is judged in such a manner by the combination of the number of the segment points and the flickering stop time of the respective segment points.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a digital display clock. [Prior art and its problems] Conventionally, in digital display watches that display the hours and minutes digitally, a pair of break points are placed between the hour display and the minute display, and the break points are set at 1. There is one that is designed to blink once every second (see Japanese Patent Publication No. 51-22837). However, in this case, even though you can confirm that the clock is working by looking at the blinking breakpoints,
To check the seconds display, you need to count the number of times the breakpoint blinks after the minute display changes. Therefore, conventional digital display watches have had the problem of not being able to determine approximately how many seconds it is when looking at the display surface that shows the time. The present invention has been made based on the above circumstances, and its purpose is to provide a digital display timepiece that can approximately determine the time in seconds. [Means for Solving Problem yA] In order to achieve the above object, the present invention arranges a plurality of break points between the hour display and the minute display to indicate the break between the hour display and the minute display. In the digital display clock, each of the plurality of breakpoints is provided so as to be able to blink, and a time period is set in which at least one of the plurality of breakpoints stops blinking within 60 seconds. This will be a practical means. [Operations and Effects of the Invention] The digital display timepiece of the present invention having the above-mentioned elliptical structure has the advantage that at least one of the plurality of breakpoints arranged between the hour display and the minute display indicates the time at which at least one breakpoint stops blinking. By providing this, there will be a time to stop blinking and a time to start blinking within 60 seconds at one break point. Therefore, for example, if the time to stop blinking is set to 30 seconds, it is possible to determine whether at least 30 seconds or more have passed since the minute display changed. Furthermore, when three breakpoints are provided, by setting the time at which each breakpoint stops blinking by 20 seconds, it is possible to judge the seconds in a range of 20 seconds. In this way, without counting the number of times each breakpoint blinks, it is possible to determine the approximate time in seconds at the current moment based on the combination of the number of breakpoints and the time at which each breakpoint stops blinking. ．． [Example] Next, the digital display timepiece of the present invention will be explained based on an example shown in the drawings. FIG. 1 is a block diaphragm showing the configuration of the digital display timepiece of the present invention, and FIG. 2 is a plan view of the digital display timepiece.

As shown in FIG. 2, the digital display watch 1 of this embodiment digitally represents the hour display 2 and the minute display 3.
Between the hour display 2 and minute display 3, a colon mark 4 (a plurality of dividing points according to the present invention) indicating a division between the hour display 2 and minute display 3 is arranged. The time displayed digitally uses a 7-segment display with a "day" pattern, and each dot (break point) 4a, 4b of the colon mark 4 uses a rectangular segment. As shown in FIG. 1, this digital display clock 1 includes an oscillation circuit 5 that uses a crystal oscillator as a time reference, a frequency division circuit 6 that divides the frequency of the pulses of the oscillation circuit 5 to produce a time signal, and It consists of a digital display section 7 for inputting the frequency-divided signal from the circuit 6 and displaying the time digitally, and a colon blinking section 8 for blinking the colon mark 4. The digital display unit 7 includes a second counter 9a, a minute counter 9b, and an hour counter 9 that operate by inputting a frequency division signal.
A clock circuit 9 consisting of C, a decoder circuit 10 that inputs a clock signal from the clock circuit 9 and converts it into a display signal, and a digital display device 11 that digitally displays the time based on the display signal of the decoder circuit 10. ．． The colon flashing unit 8 is a timer circuit 12 that integrates the frequency-divided signal.
and a colon flashing device 13 that flashes each dot 4a, 4b of the colon mark 4 according to the cumulative time of the timer circuit 12. The colon flashing device 13 lights up each dot 4a of the colon mark 4.
, 4b are blinked alternately at predetermined time intervals. In this embodiment, only one dot 4a blinks for 30 seconds, and then
Only the other dot 4b is set to blink for 30 seconds. Therefore, while one dot 4a is blinking,
The other dot 4b has stopped blinking, and similarly, while the other dot 4b is blinking, one dot 4a has stopped blinking. In addition, dot 4 that has stopped blinking
A or dot 4b may be lit or unlit. In this way, each dot 4a, 4b of the colon mark 4 is
By setting each to repeat blinking every 30 seconds, it is possible to determine whether at least 30 seconds or more have passed since the minute display 3 changed. (Modification) a> After blinking only one dot 4a of the colon mark 4 for 20 seconds, blinking only the other dot 4b for 20 seconds, and then blinking both dots 4a and 4b. With this, it is possible to judge the time in seconds within a range of every 20 seconds. b> The dividing point between hour display 2 and minute display 3 is colon mark 4 consisting of two dots 4a and 4b, but there are three dividing points, and each dividing point blinks sequentially every 20 seconds. You can also set it to repeat. This results in
Similar to the above modification example a), the time in seconds can be determined in the range of every 20 seconds. C) By setting six breakpoints and setting each breakpoint to repeat blinking sequentially every 10 seconds, it is possible to judge the seconds in a range of 10 seconds. In addition, in the above-mentioned modifications b> and C), it is also possible to determine the approximate time in seconds by blinking two or more breakpoints at the same time and changing the combination of the blinking breakpoints. However, in order to easily judge the time in seconds, it is preferable that when one of the breakpoints is blinking, all other breakpoints are either lit or off and stop blinking. ．． As mentioned above, the digital display watch 1 of the present invention has a 60
Set the time within seconds at which at least one of the multiple breakpoints stops blinking, and determine the approximate current time depending on the combination of the number of breakpoints and the time at which each breakpoint stops blinking. can determine the time in seconds.
