Abstract

PURPOSE:To enable discrimination between AM and PM only with the recognition of time, by driving display elements sequentially to display time counted over 24hr. CONSTITUTION:A clock signal generated with an oscillator 2 of a time counting circuit 1 is divided with a frequency divider 3 to output minute and hour information to a minute/hour information processing circuit 4. Then, minute and hour information being outputted in succession from the circuit 1 is counted with a counter 4a and a latch set signal is outputted sequentially to output terminals 41-46 per 10min. Then, outputs L1-L6 of a latch unit 5 composed of six latches drive corresponding LEDs 7-12 to display time for 1-2 AM, 2-3 PM... and 11-12 PM with a time display section TU. This enables the identifying of periods of time over 24hr, thereby allowing the discrimination between AM and PM only with the recognition of time.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a timepiece, and more particularly, to a timepiece that displays a measured time by sequentially driving display elements arranged in a linear manner.

"Prior Art" Conventional analog watches display the measured time by pointing to a circumferentially arranged dial face using long and short hands.

"Problems to be Solved by the Invention" The above-mentioned conventional clock had a problem in that it was difficult to distinguish between morning and afternoon because the period was -12 hours. especially,
When displaying the time in a foreign country where there is a time difference, as long as you are in Japan, it is impossible to tell the difference between morning and morning in that country by just one hour.

Therefore, one object of the present invention is to be able to distinguish between 4pm and 7am by simply checking the time. According to the present invention, an oscillator for outputting a tarokk signal of a fundamental frequency is provided. A clock means for outputting minute information and one hour information based on a clock signal outputted by the clock means, and a display element driving signal for processing the minute information and one hour information outputted by the time measuring means and driving the corresponding display element. A display element drive signal output means for outputting, a launch means for latching the display element drive signal, a display element drive signal reset means for resetting the display element drive signal, and a drive based on the display element drive signal. is,
Alternatively, it is erased by the display element drive signal reset means. The above-mentioned problems are solved by a clock that is equipped with a display section consisting of a plurality of display elements arranged in a line and that displays the time measured over 24 hours by driving the display elements one after another.

``Embodiment'' A watch as an embodiment of the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram for configuring a timepiece according to the same embodiment.

In this figure, 1 is a clock circuit. The second clock circuit has a built-in oscillator 2 for generating clock signals of the fundamental frequency. Furthermore, this timer @ □ circuit has a built-in frequency divider 3, which divides the frequency of the clock signal generated by the oscillator and is configured to output minute information and time information, respectively. .

Ul is a display unit) and is a display unit that displays the time every 10 minutes from 12:00 am.

This display unit is composed of the following components.

That is, l is a processing circuit for the minute information and time information, and this processing circuit is equipped with a counter 4a that counts the minute information and hour information successively output from the time counting circuit. Count information and time information to 1
An L active latch set signal is outputted sequentially from the output terminal 41 to the output terminal 46 every 0 minutes.

5 is a 1-hour sheep position consisting of 6111 latches.
! It is a unit. Output LL of each latch unit
, L2, L3, L4, L5, and L6 are connected to the respective anodes of the corresponding light emitting diodes 7.8.9 and 10111.12, respectively.

And light emitting diode 7.8.9.10.11.12
Each cathode of is connected to ground.

This kind of time display Uni Soto shows 1:00 a.m. and 2:00 a.m.
Time display: A total of 23,111 time display units are provided to display the time up to 11:00 p.m.

FIG. 2 is a diagram showing the time display section TO composed of the time display unit U1.

In addition, when displaying the time of a foreign country with a time difference, a time difference adding circuit that adds 1 to the time delay or advance corresponding to the time difference of the foreign country may be provided to the processing circuit for the 5-minute time information.

This additional circuit is a circuit that supplies preset data to the counter 4a, which corresponds to the time difference, for example.

Since the present invention is configured as described above, it is possible to distinguish one hour over 24 hours, and therefore it is possible to identify one hour as morning! The F residue can be identified by recognizing only time.

In addition, multiple 24-hour clocks with the above-mentioned time display section TU arranged in a 24-hour clock are provided for each country as shown in Figure 2, and each clock is delayed or advanced by the time corresponding to the time difference based on Japan's standard time. 2) to display the foreign time.

You can easily identify and confirm the time in each country without leaving Japan.

In this embodiment, a light emitting diode is used for display, but a liquid crystal may be used instead of the light emitting diode in another embodiment.
