Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is an electronic timepiece having a calendar display capable of displaying AM and PM as well as seconds.

As shown in Fig. 1, a conventional watch of this kind has a display 1 for displaying the hour, a display 2 for minutes, a display 3 for the day, a dot 4 for separately displaying AM and PM, and a display 5 for seconds. In the illustrated example, it is easy to see that it is 11:58 p.m. on the 31st, but the seconds can only be determined at the moment when 11:59 p.m.

Therefore, even if you try to set the clock to a time signal, it is impossible to read it down to the second, and in addition to the drawback that there will be an error of up to one minute, the configuration is complicated because dots 4 for morning and afternoon are separately provided. It has the disadvantage of being disadvantageous in terms of space and cost.

This invention has been developed to completely eliminate the above-mentioned drawbacks, and will be described in detail below.

Figure 2 a = elcJ6, where the part marked with 1 is the hour indicator, 2 is the minute indicator, 3 is the day indicator, 4a, 4b
are blinking displays that have three functions: seconds, minutes, and morning/afternoon divisions.

In this invention, the seconds, minutes, and morning/afternoon divisions can be displayed by changing the combinations of blinking and turning on and off of the display bodies 4a and 4b as shown in Figure 2 to e. It is.

In other words, in Figure 2, 4a is flashing and 4b is off, and if we define that the time is from 0 to 29 seconds in the morning, then 31
It can be easily read that it is 0-29 seconds of Sunday afternoon @ 11:58.

Also, in C of the same figure, 4a is off and 4b is blinking, indicating that it is 30 to 59 seconds after 11:58 a.m. on the 31st.

In Figure 2 d, 4a is blinking and 4b is lit continuously, and if this time is defined as 0 to 29 seconds in the afternoon, then 1 p.m. on the 30th.
I know that it is 0-29 seconds of 1:58.

Further, as shown in e of the figure, if 4a is lit continuously and 4b is blinking, it is determined that it is 30 to 59 seconds in the afternoon, and in this case it is 30 to 59 seconds at 11:58 p.m. on the 31st.

As shown in FIG. 3, an electronic circuit for displaying these combinations includes, for example, an input terminal T for determining morning and afternoon, an input terminal T2 for determining 0 to 29 seconds and 30 to 59 seconds, and a second signal input terminal T3, respectively. Each blinking display body 4a is connected to the impark A, the AND circuits B2-B4, and the OR circuits 0R1 and OR2, respectively.

It is good to apply it to 4b.

Further, as shown in FIG. 4, blinking display bodies 4A and 4B.

By using 4C 3, 14 ways of display can be performed, and 12 ways can be selected from these to display 6 times in the morning and afternoon.
If you divide the time by street, you can display the minutes section, morning and afternoon sections, and flash seconds at 10 second intervals.
Even more fine-grained minute section display is possible.

As described above, according to the present invention, the second flash display, the morning/afternoon division display, and the minute section display in seconds are achieved by combining the state changes of at least two blinking displays. Since the watch is configured to have a number of functions such as reading and checking the operation of the watch, it is possible to obtain a compact watch with high commercial value without increasing the cost of the watch.

Claims (1)

[Scope of Claims] 1. An electronic timepiece comprising a timepiece standard signal source, an electronic circuit section, and a display section, wherein the display section is composed of a liquid or solid display element, and the display section displays the time, calendar date, and other information. Both of them consist of two blinking displays, each of which is driven to blink by an IHz signal supplied from the electronic circuit section, as well as manual input for morning/pm discrimination and segment discrimination input supplied from the electronic circuit section. In response to
An electronic timepiece comprising a circuit that controls combinations of turning off, lighting, and blinking the respective blinking indicators. 2. The electronic timepiece according to claim 1, wherein when one of the at least two blinking indicators is blinking, the other is turned off or lit.
