Description

[Detailed Description of the Invention] The present invention relates to an electronic timepiece with an electro-optical display.

Conventional electronic watches using segment-type liquid crystal display devices are limited to displaying characters, numbers, colons, and the like.

An object of the present invention is to provide an electronic watch that displays information related to the month and date in addition to the time display, but has a good design without taking up much display space.

The present invention uses a dot matrix type display device that is common to display time, and displays the constellation symbols at an arbitrarily set date by switching them on the same display device.

The present invention will be explained below with reference to the drawings. FIG. 1 is an external view showing an embodiment of the present invention. Reference numeral 1 is a watch body, 2 is a display section, and the display section 2 is constituted by a display device having a matrix structure. 3 is a switch for displaying the time display and the constellation symbol, 4 is a mode changeover switch, and 5 is a fast forward switch for time display.

Figure 2 shows a block diagram of the main parts. Reference numeral 6 is an oscillation circuit, 7 is a frequency dividing circuit, and 8 is a timekeeping circuit.The oscillation frequency of the oscillation circuit 6 is divided into an appropriate frequency by the frequency dividing circuit 7, and the timekeeping circuit 8 outputs "month", "day" and "day". It measures time information such as "hours", "minutes", and "seconds".

Reference numeral 9 denotes a month/day setting circuit for setting arbitrary "month" and "day" information by operating the mode changeover switch 4 and the fast forward switch 5. 10 is a gate circuit which inputs the outputs of the clock circuit 8 and the month/day setting circuit 9 and selects and outputs one of them;
In addition to outputting each time information, in the mode where arbitrary month and day are set, the "month, day" of the month and day setting circuit 9 is output.
I am trying to output information.

Reference numeral 11 denotes a numeric character generation circuit that generates characters for displaying time information such as "month", "day", "hour", "minute", and "second" in numbers. Note that when there is a limit to the information displayed on the display section 2, each time information of the clock circuit 8 is selected as appropriate using an appropriate means (not shown) and displayed on the numerical display character generation circuit 1.
1. 12 is the month, date and constellation conversion circuit,
Input the "month" and "day" information from the clock circuit 8 or the "month, day" information from the month/day setting circuit 9.
Convert to one of the 12 constellations. For example, if the date entered is between March 21st and April 20th, then Aries, 4
If it is between the 21st of the month and the 21st of May, it will be converted to Taurus. 13 is a constellation display character generation circuit that generates a character for displaying the converted constellation using the constellation symbol.

Reference numeral 14 denotes a gate circuit controlled by the operation of the display changeover switch 3, which selectively takes out the outputs of the numeric display character generation circuit 11 and the constellation display character generation circuit 13. 15 is a drive circuit, and 16 is a display device corresponding to the display section 2 in FIG.

Normally, each time information of the clock circuit 8 is transmitted to the gate circuit 1.
When the switch 3 is not operated, the time information is displayed on the display device 16 as appropriate, and when the switch 3 is operated, the constellation symbol corresponding to the date is switched and displayed on the same display device 16.

Mode selector switch 4 and fast forward switch 5
When setting an arbitrary month and day, "month, day" information from the month and day setting circuit 9 is supplied via the gate circuit 10. If the switch 3 is not operated at this time, the numerical display character is taken out through the gate circuit 14, and the month and day are displayed numerically. This is used for setting the desired month and day, and can also be useful for confirming the set date if the desired month and day have already been set. Then, when the display changeover switch 3 is operated, the constellation character corresponding to the set "month, day" information is taken out through the gate circuit 14 and the constellation symbol is displayed on the display device 16.

Figures 3a, b, and c are plan views of the display unit 2 showing different display examples, and a is a time display with "12 o'clock".
37 minutes'', and b and c represent the constellation symbols of ``Aries'' and ``Taurus,'' respectively.

As described above, the present invention converts month and day information arbitrarily set by the month and day setting means into constellation symbol information, switches it with time information measured by the clock means, and supplies it to the matrix type display means. You can know the constellation of the date on the same display means that displays the time. Furthermore, according to the present invention, a variety of arbitrary figures can be displayed, making it possible to provide a variety of electronic watches.
