Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improved battery-operated wristwatch.

The present invention relates to a battery-powered wristwatch having an electric display mechanism, and to a battery-powered wristwatch in which the display mechanism is also provided with a function of displaying data from an electronic calculator.

Currently, the proportion of wristwatches that use batteries as an energy source, such as battery-powered wristwatches and electronic wristwatches (hereinafter collectively referred to as battery-powered wristwatches), is gradually increasing.

Among battery-powered wristwatches, digital battery-powered wristwatches that display the current time numerically are also becoming popular as display parts improve.

The display of digital battery watches most commonly uses light emitting diodes or liquid crystals, and with the development of low-power display components, it is the most direct way to tell the current time. It uses an effective digital display method.

In this case, the dial on the face of the watch most commonly has a total of six digits: two digits for the hours, two digits for the minutes, and two digits for the seconds.

Along with the development of display components, the circuits for battery-powered wristwatches have also become more compact.Currently, battery-powered wristwatches using crystal oscillators are equipped with a 15-stage frequency divider that divides the frequency of 16,384Hz in 0.5 steps. Q, so much so that it is contained in one 5mm square chip.

In this way, the miniaturization of circuits is progressing, and in the case of electric watches with electric displays, the electronic circuits that make up most of the internal structure have become smaller, and when considering the volume of the wristwatch, the There is plenty of room for other electronic circuits as well.

On the other hand, it would be a waste to limit the size of this wristwatch, as the circuits for two-digit electronic desktop calculators now consist of one or two chips. Therefore, the display function mechanism should and can be used not only for displaying the time, but also for displaying other useful data when there is no need to know the time.

As mentioned above, the circuit that has all the functions of a 12-digit electronic desktop calculator is made up of one or two chips, so the circuit is housed in another part of the wristwatch and the circuit for the electronic calculator is made up of one or two chips. By combining the display with that of current watches and adding an ultra-compact numeric keypad and function keys, a battery-powered wristwatch can be used as an electronic calculator.

In addition, by making the display parts of electronic thermometers, electronic hygrometers, electronic discomfort index meters, electronic tape measures, radio dials, etc. double as the display parts of current electronic wristwatches,
The field of battery-operated wristwatches became more widespread and its commercial value increased, and the impact of this invention on this field was enormous.

An example of the use of the present invention will be explained below with reference to the drawings.

FIG. 1 is a block diagram showing a battery-operated wristwatch in which a timepiece section 12 and a calculator section 13 are housed together in a wristwatch 11. As shown in FIG.

This circuit can be operated as a clock or a calculator by switching the connection of a battery 16 for energy using a changeover switch 15, and by switching the switch 15, the liquid crystal display section 17 can display the time. ,
It also switches whether calculation data is displayed or not.

When used as a calculator, the key for typing is 14 as shown in the figure.

If the display is 6 digits and the calculation content is 12 digits, it is also possible to display the lower 6 digits first and then display the upper 6 digits by pressing the shift switch.

What is shown in FIG. 2 is an external view of the battery-operated watch with a built-in calculator shown in FIG.

21 in the figure is a display, and this figure shows the calculation results rather than the time.

22 is a changeover switch between a clock and a calculator, and 23 is a key for data input.

As detailed above and illustrated in the main text, the battery-operated wristwatch according to the present invention not only displays the original time, but also has the function of displaying the data on the electronic calculator display using the changeover switch. Moreover, since the display part is shared, this can be done more easily and the market for wristwatches can be expanded.

Furthermore, the present invention makes it possible to incorporate a mechanism for displaying computer data into a wristwatch without impairing the compactness and long life of the wristwatch.

In other words, by driving both the timekeeping mechanism and the electronic calculation mechanism with a common battery, the timepiece body can be made smaller, and the electronic calculation mechanism can be selectively displayed in order to extend the life of the same battery. By using a switch and using a liquid crystal display with low driving power as the display,
This helps extend the lifespan of batteries.

This invention is the first to practically incorporate an electronic calculation mechanism into an electronic wristwatch.
