Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an electronic timepiece equipped with an electro-optical display device such as a liquid crystal or a light emitting diode, and having improved operating means.

In recent years, electronic watches with electro-optical display devices have been rapidly becoming popular, but these electronic watches have a variety of display modes, i.e., in addition to the normal hour and minute display, for example, a calendar month and day display, and an alarm display. In the case of a multi-function watch that has an hour and minute display for the set time, or a display for when the time is being adjusted, these can be switched sequentially in a way that is easy for the user to understand. If you change the mode and continue reading incorrect information,
There was no display selection method that would prevent the risk of erroneous operation of the switch.

In addition, ease of adjusting the time, etc. and safety against erroneous operation after adjustment have become issues. Taking both of these into consideration, wristwatches have been designed to make it easier to adjust the external operation members by placing them inside the case. A device that uses a jig or the like to perform correction operations, or a device that uses a watch like a conventional mechanical watch and allows correction operations to be made only by pulling the watch out of its normal state. and so on. According to the present invention, a plurality of function display modes are cyclically selected and displayed on one display section using a single switch, and one of the function display modes is set as a basic display mode, and other display modes are selected. If the display mode is left unattended for more than a predetermined period of time, it will automatically return to the basic display mode, thereby preventing confusion in reading or erroneous switch operation caused by forgetting to return to the display mode or switching to another display mode due to erroneous operation of the switch. The purpose is to
Hereinafter, the present invention will be explained based on the drawings. FIG. 1 is a block diagram showing one embodiment of the present invention, in which 1 is a time standard oscillation unit including a crystal oscillator, etc., and 2 is the time standard oscillation unit. 3 is an electro-optical display device using a liquid crystal, a light emitting diode, etc.; 4 is an electronic circuit for selectively switching the contents of the electronic circuit 2; A display switching circuit for displaying on the display device 3, 5 a display selection switch terminal, 6 a correction selection switch terminal, 7
Reference numeral 8 denotes a correction switch terminal, and 8 a display selection circuit which switches the display contents of the display device 3 through the display switching circuit 4 in response to an input from the display selection switch terminal 5.

Reference numeral 9 denotes a correction function selection circuit operated by input from the correction selection switch terminal 6; 10 a correction input control circuit;
It controls the destination of the correction input from the correction switch terminal 7.

Therefore, if you want to modify a certain function, give an input to the display selection switch terminal 5 to switch to the display that includes the function you want to modify, and then give an input to the modification selection switch terminal 6 to change the display contents. After selecting the function to be modified from among them, the function is modified by applying an input to the modification switch terminal 7. Also, 1
1 and 12 are timers which reset the display selection circuit 8 and correction function selection circuit 9, respectively, to predetermined initial states after a certain period of time after the input is applied.
Here, when at least one of the display selection circuit 8 and the correction function selection circuit 9 is reset to the initial state, the correction input control circuit disables the correction input from the correction switch terminal 7 and prevents correction from being performed. Please set it to 10. By doing so, it is possible to prevent erroneous operation even when input is given to the switch terminals 5, 6, and 7 using a simple external operation member such as a bush button. When the display selection circuit 8 and the correction function selection circuit 9 are configured using flip-flop circuits, the outputs of the timers 11 and 12 should be connected to the set terminal or reset terminal of the respective flip-flop circuits. Good. Further, 13 is an 0R circuit, which operates the timer 12 not only by the input from the modification selection switch terminal 6 but also by the modification switch terminal 7, and when the timer 12 is in operation, the starting point is It is something to be updated. 14 is also an 0R circuit, which operates the timer 11 by both the output of the 0R circuit 13 and the input from the display selection switch terminal 5, and if the timer 11 is in operation, the This is to update the starting point.

That is, if an input is given to any of the switch terminals 5, 6, and 7 within the time set in the timer 11, the starting point of the timer 11 is updated, and the display selection circuit 8
is not reset, and if an input is given to either of the switch terminals 5 and 6 within the time set in the timer 12, the starting point of the timer 12 is updated, and the correction function selection circuit 9 is not reset. Therefore,
Even if the set time of the timers 11 and 12 is set to a relatively short time (for example, about 1@), the starting points of the timers 11 and 12 can be easily updated by inputting from the correction switch terminal 7, etc. Therefore, there is almost no need to worry about resetting the timer during the correction operation, and since the correction input is immediately reset to an invalid state after the correction operation is completed, there is no risk of erroneous operation. Next, 15 is an 0R circuit for resetting the correction function selection circuit 9 to a predetermined initial state not only by the output from the timer 12 but also by the input from the display selection switch terminal 5. When an input is given to switch the display, the correction function selection circuit 9 is always reset to the initial state, so the operation is easy to understand, and the input from the correction switch terminal 7 is disabled in the initial state. If the correction input control circuit 10 is set so that the error occurs, erroneous operations can be prevented. FIG. 2 shows, in the embodiment of FIG. 1,
As the contents of the electronic circuit 2, for example, "゜hour゛,゜゜minute゛,
It has a clock counter that counts ゜゜month゛ and ``old゛'' and a memory that stores ``hour゛'' and ゜゜minute゛ for alarm, and by giving input to the display selection switch terminal 5,
This is an example of switching and displaying them on the display device 3. In the figure, the display switching path indicated by a solid line is connected to the display selection switch terminal 5 so that the display selection circuit 8 is not reset by the timer 11. This shows the case where input is given continuously, and the function display mode a+b-+cm+d+a-
It circulates and is switched in the order of +b...

In addition, the display switching paths indicated by broken lines in the figure are B, c, and d.
This indicates a case where no input is given to the timer 11 for a certain period of time or more set in the timer 11 in each display state, and the display selection circuit 8 is reset by the output of the timer 11, and the B, c and display correction modes The display state d directly returns to the display state a. Here, the display state a corresponds to the initial state of the display selection circuit 8, that is, the basic display mode, and in this state, even if an input is given to the correction selection switch terminal 6, the correction function is not selected, and the correction switch Even if a correction input is given to terminal 7, it becomes invalid and no correction is performed. Therefore, in state a,
It is preferable to display the functions that are most needed during normal carrying, and in this embodiment, the functions of "゜hours" and "゜゜minutes" in the time counter are displayed, and the functions of 1 full function are displayed. In addition, b indicates the "man" and "old" functions in the time counter, and c indicates the "hour" and "minute" functions in the alarm memory, respectively. , and when an input is given to the correction selection switch terminal 6 in the display state of b and C, the correction function is selected, and by the correction input from the correction switch terminal 7, In the state of function "c", it is possible to modify the alarm's "hour" and "minute" functions. d displays the same function as the display in a above, but in the state of a, the display function cannot be corrected, whereas in the state of d, the correction selection switch terminal 6 is A correction function is selected by providing an input, and a display function can be corrected by a correction input from the correction switch terminal 7. Here, a<15
d display the same function, but it is very easy for the user to understand if the difference in whether the display function can be modified is displayed on the display screen.For example, d Possible methods include adding a mark to state , or making the colon blink in state a and stop blinking in state b. Also, it is preferable to distinguish the difference between states b and c from state a by using marks as in this embodiment. FIG. 3 shows an example of changes in the display screen when the correction function is selected by applying an input to the correction selection switch terminal 6 in each of the display states shown in FIG. 2B, c, and d. This is a representative example of the situation.

First, e indicates a case where the correction function selection circuit 9 is in an initial state, and even if a correction input is applied to the correction switch terminal 7, the display function is not corrected. Next, modify selection switch terminal 6
When an input is given to , the display surface changes to the state f. That is, the display of "゜month" disappears from the display screen, and the display of "゜゛" remains.The function of "old" is selected and it is displayed that it can be corrected.At this time, a correction input is given to the correction switch terminal 7. Then, the ゜old゛ function is corrected.Next, when an input is given to the correction function selection switch terminal 6, the display screen changes to the state of g, the month display remains, and the input from the correction switch terminal 7 is changed. By inputting corrections, it becomes possible to modify the functions of ゜MAN゛.
Hereinafter, when an input is given to the correction selection switch terminal 6 within a certain period of time set in the timer 12, e→f-g-+e→f... as shown by the solid line in the figure. However, if no input is given to the timer 12 for a certain period of time set in the timer 12 in the display state of f and g, the correction function selection circuit 9 is returned to the initial state by the output of the timer 12. Since it is reset, it returns to the display state e by following the path indicated by the broken line in the figure. In this case, if the set time width of the timer 12 is set smaller than the time width of the timer 11, the above relationship will hold, and after maintaining the display state of e by the difference between the time widths of the timer 11 and timer 12, The display state is returned to a as shown in FIG. 22.

Alternatively, the time widths of both timers 11 and 12 may be made the same, and all display states may be returned to display state a. Incidentally, it is also possible to take out a part of the correction method shown in FIG. 3 and apply it to a watch having only hour and minute functions.

In other words, if you remove the dotted lines on ゜a and always display only the hours and minutes, switch to the correction function like F and g, make corrections, and leave it alone, it will return to the original F hour and minute functions. This is an automatic recovery method.

This has the effect of making simple clock corrections simpler. FIG. 4 shows another embodiment of the display switching method shown in FIG. This is the case when the display is switched to a<! 1. Since the display function of d is the same, by removing a from the display switching circulation path and displaying b-+c-d in a circular manner, the speed of display switching can be accelerated, and at the same time, 1
In addition to the inconvenience of having similar display states twice during circulation, correction functions can be selected for all B, c, and d, making correction of display functions quick and easy.

Note that the display switching path indicated by a broken line in the figure shows the case where the display selection circuit 8 is reset by the output of the timer 11, as in the case of FIG. As described above, the present invention resets the display state or the selection state of the correction function to a predetermined initial state using a timer, thereby allowing the display to be left as it is after performing operations such as switching the display or correcting the display function. Even if you change the settings, it will automatically return to the original state, eliminating the hassle of having to manually manipulate something to return to the original state.Furthermore, in the predetermined initial state, correction input is disabled. If the setting is made so that it is possible to prevent erroneous operations while carrying a wristwatch or the like.

Also, if you update the starting point of the timer through correction input, etc., even if the timer setting time is relatively short,
Since it is not reset during the correction operation, it is possible to make corrections calmly, and moreover, it is possible to quickly return to the initial state after the correction operation is completed. Regarding the order of display switching shown in Figure 2 or Figure 4, the initial state is considered as the starting point and the display is normally switched in descending order of frequency of use. By preparing in advance the means to change the movement, it is possible to change the product using the same movement depending on market trends, sales tactics, etc. This is especially true for watches with alarms or chronographs.
