Description

[Detailed explanation of the idea] The present invention relates to an optional mechanism for an all-electronic watch.

All-electronic watches made of photoelectric digital display elements and IC circuits can have many functions in addition to the additional functions such as calendar displays and chronographs that were added to conventional mechanical watches with pointer displays. Various functions can be considered, such as alarms, gas detection counters, pagers, calculation mechanisms, etc., but in order to make a watch equipped with these functions, including conventional additional mechanisms, the following should be considered. There was a problem.

In other words, the frequency of use of these functions varies depending on the time of use, place of use, and user, so in order to make a versatile watch with added functions, it is necessary to add as many functions as possible. This results in the addition of functions that are completely unnecessary or rarely used by some users, which increases costs, and also poses technical problems in that it is difficult to provide many function display bodies on one display device. It was a calamity.

Therefore, a watch with limited additional functions can be considered, but if the additional functions and additional function display are integrated with the clock function and time display, etc., at the stage of making the IC circuit and display device of the watch, IC circuits and display devices are not versatile, and when users require various functions,
This means that I have to buy a new watch each time.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide an optional mechanism for a watch, which is characterized in that it is used by being additionally connected to the watch body, thereby solving the above-mentioned problems.

This will be explained below with reference to the drawings.

FIG. 1 is a basic configuration diagram for explaining the optional mechanism for a watch according to the present invention.

Reference signal oscillation source A, frequency dividing circuit B, instrument circuit C, decoder drive circuit D, photoelectric display device E, battery F, booster circuit G,
The block consisting of the control input device H constitutes the main body of the watch.

The option mechanism 1 is composed of an option function circuit, a decoder drive circuit D', and an option function display device E', and the option functions are operated by an option control input device H'.

The optional mechanism 1 is the output terminal 1 of the clock circuit IC2.
b, output terminal 1g of the booster circuit and output terminal I of the counting circuit
It is connected to C at three places.

Therefore, when a manufacturer sells a watch with optional functions, it is necessary to either incorporate the basic structure of the watch as shown in Figure 1 into a single watch case, or to sell the watch with the optional control input device included. The optional mechanism 1 can be placed in a case separate from the watch case of the watch body and sold so that the user can make additional connections as needed.

Moreover, the main body of the clock, which is centered around this clock circuit IC2,
Since it can be sold as a watch with a regular time display, completely separate from the optional mechanism, this watch itself has versatility, and the manufacturer can expand its customer base.

And if you configure the connection end of the watch body to be compatible with optional mechanisms with various different functions,
In addition to increasing the versatility of this watch, the user can also connect optional mechanisms, allowing the user to
If you purchase a watch that comes in two watch cases,
All you have to do is purchase additional optional mechanisms that have the functions you need, and then connect these optional mechanisms to the watch body depending on the time and place of use.

The optional functions shown in the basic configuration diagram in Fig. 1 include a chronograph, counter, arithmetic function, etc., and if the alarm function is to be retained, an output terminal is provided in the counting circuit C, and the optional The configuration is to connect it to the functional circuit (2).

Figure 2 shows an example of a wristwatch in which the user can add this alarm function as an optional mechanism. It is an overall view when a mechanism is added.

Number 23 is a connection end for additionally connecting an optional mechanism to the watch body, which is structured like a connector on the watch body.
It can be fixedly connected to the printed circuit board shaped connection end of the optional mechanism.

Of course, it is also possible to configure this connection end to be of a plug insertion type.

The connecting end 23 of the watch body is mechanically fitted into a lid 2 made of metal or plastic that is relatively easy to remove when no optional mechanism is connected.
4 and sealed.

In this case as well, it is conceivable to seal the connection end 23 of the watch case in the form of a shutter, or to prepare a cover made of metal or non-metallic material and add it as necessary.

In addition, if the watch body is designed to be compatible with an optional mechanism that has other functions such as a chronograph, it is necessary to provide an extra number of connection terminals as necessary, or to change the characteristics of different optional mechanisms. A connection terminal is provided to electrically read the information, and the circuit section of the watch body is configured to identify the signal read by the connection terminal and output a signal suitable for each optional mechanism based on the results. Alternatively, it is also possible to consider a structure in which the number of connection terminals is reduced.

Figure 3 shows optional features such as day of the week display function, month and date display function including uncorrected end of month and uncorrected leap years;
This is a basic composition diagram of this invention assuming a time display function such as hours and minutes separate from the main body, a function to display the deadline date and time remaining until the deadline time, an alarm function, etc. The symbols are shown in Figure 1. It complies.

The control input devices H and H' are configured so that one each is used for the watch body H and the optional mechanism H', or if the day of the week or month/day display function is used as an optional mechanism, the control input device Depending on the configuration of H, it is also possible to eliminate the control input device H' for the optional mechanism.

Note that number 4 is the circuit IC of the watch body, and number 5 is the option circuit IC.

Figure 4 shows an example of a case where a manufacturer makes a wristwatch with an optional mechanism with a tag display function based on the basic structure diagram shown in Figure 3. Figure 4 is a diagram showing the layout of the LCD panel and IC circuit. This is an external view of the completed wristwatch, and the symbols and numbers are the same as in Figure 3.

In this case, the timepiece circuit IC4 and the display device E can be used alone in a timepiece without adding an optional mechanism, so the timepiece circuit IC4 and the display device E have versatility.

Fig. 5 is a basic configuration diagram when the battery life warning function is additionally connected as an optional mechanism.
is composed of a battery life warning function circuit 52, a display drive circuit 53, and a liquid crystal display device 54.

FIG. 6 shows an embodiment of a wristwatch including the optional mechanism shown in FIG.
The display body 55, which was lit, blinks or goes out.

In this case, an optional mechanism is added to a watch main body including a clock display device equipped with a time display 56 and a calendar display 57 at the manufacturer's stage.

FIG. 7 is a diagram showing one basic configuration according to the present invention when the optional mechanism 71 includes a decoder drive circuit J and an optional display device K.

Other symbols are the same as in FIG.

In this case, as an option display, analog second display, day of the week, date display, etc. can be directly considered, but the counting circuit C
If the block includes various functional circuits such as an alarm and a chronograph in advance, the optional mechanism 71 is configured to be able to display a display corresponding to those functions.

In this case, there is a frequency dividing circuit B and a counting function circuit C, and the corresponding decoder drive circuit D does not include a decoder drive section for displaying various functions.

Furthermore, when the various functional circuits described above are included in the clock of the counting circuit C, the decoder drive circuit D also includes a decoder/drive section corresponding to these various functions, and as an optional mechanism, only the display device is included. I can also think of a similar precept.

This is a method that can be considered when making a circuit IC for a watch body, in which the cost is not too high by adding various functions that are used relatively frequently.

As described above, the use of the watch option mechanism according to the present invention is extremely advantageous in the production and use of multi-function display type watches.
