JPH06242263A - 24-hour timepiece with changeable time displaying numeric character on dial - Google Patents

Abstract

PURPOSE:To discriminate the forenoon or afternoon at a glance by using a liquid crystal disc in a display mechanism and changing over the time figures of a timepiece equally divided into 12 sections to forenoon display and afternoon display with the elapse of time. CONSTITUTION:Time figures are provided on the circumference of a circle equally divided into 12 sections of the liquid display device 3 on the dial 2 of a digital type mechanical timepiece 1. Time figures for the forenoon and afternoon are respectively alloted so that 0, 12 and 24 can be displayed on the crystal 3 present at a 12 o'clock position and 1 and 13 can be displayed on the crystal 3 present at a 1 o'clock position and 2 and 14 can be displayed on the crystal 3 present at a 2 o'clock position and connected to a time casting circuit equipped with a time casting memory chip and a reset circuit. Timepiece display characters are changed only by an electric clock mechanism and not connected with the movement of the mechanical timepiece. Only by looking this timepiece, the forenoon or afternoon can be confirmed and, therefore, this timepiece is suitable for an old man.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a 24-hour display timepiece in which the time display characters of the dial of a pointer type timepiece are changed according to the time.

[0002]

2. Description of the Related Art As is well known, a pointer type timepiece displays a number from 1 to 12 or various kinds of display corresponding to this on a circumferential line divided into 12 equal parts. It was the basis. Of course, there is a 24-hour clock in which numbers 1 to 24 are displayed on a circle divided into 24 equal parts, but this is not common because it is installed mainly in workplaces that are active on a global scale.

[0003]

In recent years, the number of elderly people with dementia and the like is increasing in combination with the aging of the population, but among these elderly people, there is no sense of time. It can be said that it is not possible to distinguish between 7 o'clock and 7 o'clock at night, and the conventional form of 1 to 1 that depends on the perception of a healthy person
It was difficult to teach the distinction between morning and day with only 2 display clocks. Therefore, in the present invention, the time display shows the morning display and the afternoon display on the circumference divided into 12 equal parts, and the time display is 0.
It is possible to distinguish between am and pm at a glance by displaying the numbers from 1 to 24.

[0004]

In order to achieve the above object, the inventor of the present invention has set the time number of a timepiece divided into 12 equal parts on the dial of a pointer type timepiece having a conventional mechanism with the passage of time. , The traditional 12 o'clock display at noon is 0, 12,
Instead of 24, the display at 1 o'clock is 1 and 13, the display at 2 o'clock is 2 and 14, the display at 3 o'clock is 3 and 15, the display at 4 is 4 and 16, and the display at 5 is 5 and 17. The display of 6 is 6 and 18
The display of 7 is 7 and 19 and the display of 8 is 8 and 20 and 9
Is displayed on 9 and 21, 10 is displayed on 10 and 22, 11
The display of 11 is set to 11 and 23 by an electrical configuration device that operates and displays, and when the time hand of the clock passes 23:00 (11:00 pm), the display of the center (12 o'clock position) is 24 hours.
When the hour hand reaches the 12 o'clock position, this display changes to 0 at the same time and the other time displays also change from 1 to 11, and when the hour hand passes 11 o'clock, the center (12 o'clock position) 0 When the hour hand comes to this 12 o'clock position, the indications from 1 to 11 change from 13 to 2
It is designed to change to 3, and this process is repeated thereafter. Of course, a reset function is provided to initialize the time display or reset it in case of a failure. This reset function enables the batch display setting of 0 to 11 am and the batch display setting of 12 to 23 pm. . Incidentally, the movement of the clock for displaying such numbers is carried out by incorporating a program for indicating such movement into the IC, and a liquid crystal panel is used as a display mechanism.

[0005]

With the 24-hour display clock of the present invention configured as described above, the time is automatically set after the time is set automatically by checking the hour hand position of mechanical operation with the first reset function according to the morning and afternoon. When the hour hand moves to 23:00, the number at the center (12 o'clock position) changes from 12 to 24 and the hour hand moves to 24 hours.
It changes to 0 at the same time, and other numbers are 1 for morning
When the hour hand reaches 11 o'clock, the display of 0 changes to 12 and when the hour hand reaches 12 o'clock, other numbers also change to the display of 13 to 23 for the afternoon.

EXAMPLES Examples will be described with reference to the drawings.
On the dial 2 of the pointer type mechanical timepiece 1 shown in FIG. 1, the liquid crystal displays 3 are provided on the circumferential lines divided into 12 equal parts, and 0, 12, 24 are provided on the liquid crystal display at the 12 hour position. , The liquid crystals in the hour position display 1 and 13, the liquid crystals in the time position display 2 and 14, and the liquid crystal in the time position display 3 and 15. Liquid crystal in position 4 and 16
, 5 and 17 are displayed on the liquid crystal at the time position, 6 and 18 are displayed on the liquid crystal at the time position, and 7 and 19 are displayed on the liquid crystal at the time position. The liquid crystal at the position of 8 and 20 are displayed, the liquid crystal at the time of the position is displayed at 9 and 21, and the liquid crystal at the time of 10 is displayed at the position of 10 and 22, 11 and 23 are displayed on the liquid crystal at the time position, and each liquid crystal is arranged on the dial, and each is electrically connected to the time signal circuit including the time signal memory chip and the reset circuit as shown in FIG. The change of the time display character in the mechanically connected thing changes only by the electric clock mechanism, and there is no cooperation between the movement of the mechanical timepiece and this clock mechanism. It should be noted that FIGS. 2, 3 and 4 show changes in the numbers displayed in the morning and afternoon due to changes in time. In addition, it is possible to change the time display only to display only 1 to 12 and 13 to 24, and it is also possible to easily change the color between am and pm. It goes without saying that it is easy to change the.

The embodiment shown in FIG. 6 shows an example in which only the numeral display portion is annularly formed integrally with a liquid crystal plate and mounted on a timepiece dial.

Is the same as

Instead of attaching the time display liquid crystal plate to the mechanical timepiece as in the above-mentioned two embodiments, the timepiece can be displayed on the liquid crystal display including the hands, and such a timepiece can be displayed as an image on the television receiver or the like. .

[0009]

Since the present invention is configured as described above, it has the following effects. Since the time characters are individually displayed on the dial of the mechanical clock with a liquid crystal display, even a large wall clock can display relatively large characters, making it easy to view from a distance even in the morning and afternoon. The display time can be read, and in the case of a small watch, the entire character display part can be made into a donut-shaped liquid crystal plate and fixed on the dial to make it smaller. If it is displayed, the shape can be further downsized, and even when there is no TV program, such a clock can be displayed as an image. Since these clocks are always displaying 24 hours, you can only see the numerical display. Without any explanation or thought, morning and afternoon recognition has a noticeable effect.
