Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a correction device for correcting the display of a digital display electronic timepiece or correcting the ON/OFF state of an alarm function provided as an additional function.

In recent years, so-called digital electronic watches, which are equipped with a crystal oscillator as a time standard and display the time using an electro-optical display device such as a liquid crystal display device, have rapidly become popular. Furthermore, various time adjustment devices have been proposed for the above-mentioned digital electronic watches, but typical ones include a first push-button switch for selecting an element to be corrected, and a device for supplying a correction signal. By providing a second push-button type switch for the purpose of
An example is a correction device configured to correct the time.

However, since the conventional correction apparatuses described above are configured to sequentially select the correction targets one by one, it takes a lot of effort to select the desired correction target, Display and display regarding functions
When modifying ON, OFF, etc. status all at once,
This method has drawbacks such as extremely complicated operations. In particular, digital display type electronic watches in recent years not only have the function of simply displaying time such as hours, minutes, and seconds, but also have additional functions such as calendar display functions such as date, day of the week, and month, and alarm devices and timer devices. In addition to having many elements to be corrected, the display device itself is also often used for each function and is configured so that the display target can be switched, making it difficult to operate when making corrections. It had also become extremely time-consuming.

On the other hand, in the past, the display was corrected by controlling the opening and closing of the correction input switch by rotating an external operation member (hereinafter referred to as "reuse") that could be set at multiple axial positions and also capable of rotational operation. A modification device has been proposed that is configured to perform. Such a correction device has the advantage of being easy to operate and understand, but as the functions of a watch increase as mentioned above, if you want to make corrections for a predetermined function all at once, Correct input by rotating the reuse alone is insufficient.
For example, in the time display function, the hour. Minute. Three elements for seconds, month for calendar display function. Day. The three elements of the day of the week, and the hour in the alarm function. Minute. Generally, there are three elements to be corrected for each function, such as three elements for the ON to OFF states, but when the correction input is only by rotation of the reuse, there are three elements to be corrected. It is difficult to modify the above correction targets. For this reason, for a specific function that has three elements to be modified, it is necessary to configure the drawer position of the reuse to be different for any one of the elements to be modified. This resulted in a correction device that lacked uniformity and clarity.

The present invention eliminates the drawbacks of the conventional correction devices described above, and an object of the present invention is to eliminate the operation of changing the axial position of the crown once the correction state regarding the time display function is set. It is possible to execute correction input for hours, minutes, and seconds without requiring a new mode switching operation to switch the correction target, and once the correction status regarding the alarm function is set, It is possible to execute correction inputs for the hours and minutes of the alarm time and for turning the alarm function ON or OFF without requiring an operation to change the axial position of the reuse or a new mode switching operation to switch the correction target. The object of the present invention is to provide a correction device configured to allow the correction.

is the aforementioned mode switching means and correction control switch.
A switch input control circuit is configured to simultaneously control the input functions of the correction input switch _S4 and the lamp lighting switch _S2 according to the states of both the switch _S3 and the switch S3.

Next, the operation of the correction device of this example will be explained.

However, the circuit shown in Figure 3 operates with positive logic, and when it is written simply as [H], it means that it is at the logical [H] level, and when it is written simply as [L], it means that it is at the logical [H] level. If it is, it indicates that it is logically at the [L] level.

The mode switching system register 24 described above is
With the state of 100 shown in Figure 3 as the initial state,
Each time the mode changeover switch _S1 is closed, the contents are sequentially shifted by one step. That is, the initial state of 100 above corresponds to the time display mode, and for example, in FIGS. 1a and 1b, the time of 12:35:58 am is indicated on the liquid crystal display device 1. On the other hand, as shown in FIGS. 1a and 2a, when the sleeve 2 is in the normal position 2a, the mandarin door 4 and the terminal pin 5 are not in contact with each other, and the correction control switch is not in contact with the terminal pin 5. S ₃ is in the open position. As a result, whatever the contents of the shift register 24, the modified control gate means 2
The output sides of the AND circuits 26 to 28 of No. 5 are held at the [L] level, the correction enable signal is not output, and the correction operation instruction sections 1b, 1c, and 1d are turned off. Therefore, in this state, the AND of each correction signal input gate means 31, 35, 39 described above is
Since all the circuits are in the OFF state, the display etc. will not be corrected even if the reuse 2 is rotated in either the left or right direction and the protrusion 3a comes into contact with the switch contact spring 6 or 7. do not have.
When the reuse 2 is pulled out to the first pull position 2b, the mandarin duck 4 is regulated to be in contact with the terminal pin 5, and the correction control switch _S3 is closed. Therefore, in this state, depending on the contents of the shift register 24, the output side of any one of the AND circuits 26 to 28 of the correction control gate means 25 outputs a correction enable signal of [H] level, and at the same time Operation instruction section 1b, 1c, 1
d becomes lit. That is, as described above, when the contents of the mode switching shift register 24 are in the state of 100 and the watch is in the time display mode, if the reuse 2 is pulled out to the one-step pull position 2b, the correction control gate means 25 is activated. AND circuit 26~
28, only the output side of the AND circuit 26 is [H]
AND circuits 32 to 34 of the gate means 31 for outputting a level correction signal and inputting a time correction signal
It becomes ON state. Also, at this time, the liquid crystal display device 1
The state is as shown in FIG. 1b.

Therefore, in this state, the correction operation instruction section 1
When the reuse 2 is rotated to the right (arrow A) in accordance with the display of b, and the protrusion 3a and the switch contact spring 6 are brought into contact, the AND circuit 29 is turned on, and the AND circuit 29 and the AND The 1 Hz output signal from the frequency dividing circuit 12 is supplied via the circuit 34 to the correction signal input terminal of the hour counter forming the time counting counter 13, so that the hour display is corrected. Further, in the above state, if the reuse 2 is rotated to the left (arrow B) direction according to the display on the correction operation instruction section 1c to bring the protrusion 3a into contact with the switch contact spring 7,
AND circuit 30 becomes ON state, and the AND circuit 3
0 and a 1 Hz signal is applied to the correction signal input terminal of the minute counter via the AND circuit 33 to correct the minute display. Furthermore, in the above state, when the lamp lighting switch _S2 is closed according to the display on the correction operation instruction section 1c, one pulse signal formed by the differentiating circuit 43 is transmitted through the AND circuit 32 at that moment. , is supplied to the reset terminal R of the seconds counter and frequency divider circuit 12, and the seconds display is reset to zero.
In other words, as described above, when the watch is in the time display mode and the reuse 2 is in the one-step pull position 2b, the reuse 2 is moved to either the left or right side according to the instructions from the correction operation instruction sections 1b, 1c, and 1d. It is possible to modify all display elements in the time display mode by rotating in the direction or closing the lamp lighting switch _S2 .

On the other hand, when the mode changeover switch _S1 is closed once while the reuse 2 is pulled out to the first position 2B as described above, the contents of the mode changeover shift register 24 change from the initial state of 100 described above. After one step transition, the content becomes 010, and the watch enters the calendar display mode (displaying Monday, July 3rd) as shown in Figure 1c, and the correction operation instruction sections 1b, 1c, and 1d also light up. It's summery. Further, in this state, the correction control gate means 2
Among the AND circuits 26 to 28 of 5, the AND circuit 27
Only the output side of the calendar correction signal input gate means 35 outputs a [H] level correction enable signal.
AND circuits 36 to 38 are maintained in the ON state.
Therefore, in this state, the correction operation instruction parts 1b, 1c
In response to the instruction, rotating the reuse 2 to the right will selectively correct the month display, and rotating the reuse 2 to the left will selectively correct the date display. Note that the operation of the circuit in this case is the same as in the case of correction in the time display mode described above, so a description thereof will be omitted. In this state, each time the lamp lighting switch _S2 is closed, one pulse signal formed by the differentiating circuit 43 is supplied to the correction signal input terminal of the day of the week counter via the AND circuit 36. , the display of the days of the week will be corrected.

Next, when the mode changeover switch _S1 is closed again from the above state, the contents of the shift register 24 will shift to the state 001, and the clock will display an alarm as shown in FIG. 1d or e. mode (alarm set at 10:30). Therefore,
In this state, according to the instructions from the correction operation instruction parts 1b and 1c, rotating the reuse 2 clockwise will correct the hour display of the alarm set time, and rotating it counterclockwise will correct the minute display. will be done. On the other hand, in this state, each time the lamp lighting switch S ₂ is closed, one pulse signal formed by the differentiating circuit 43 is supplied to the toggle terminal T of the FF 15 via the AND circuit 40. will alternately repeat the set state and reset state. That is, when the FF 15 is in the set state, the AND circuit 20 is also turned on.
state, the buzzer 22 is controlled to be driven by the output of the coincidence detection circuit 19, and the alarm function is turned on. Also as above FF
15 is in the set state, the alarm status display section 1a lights up and the alarm function is activated.
It is configured to clearly indicate that it is in the ON state. From the above state, turn the lamp lighting switch _S2 to 1 according to the display on the correction operation instruction section 1d.
When the switch is closed again, the FF 15 is reset, the AND circuit 20 is set to OFF, and the alarm function is set to OFF. Therefore, in this state, even if the alarm set time reaches and the output side of the coincidence detection circuit 19 becomes [H] level, the buzzer 22 will not be driven, and the alarm state will continue as shown in FIG. 1e. The display section 1a is also turned off.

Furthermore, from the above configuration, when the mode changeover switch _S1 is closed once, the shift register 24
will return to the initial state of 100, that is, the time display mode.

Therefore, according to the above configuration, when the reuse 2 is pulled out to the first pull position 2b,
The mode changeover switch _S1 changes the display mode of the watch, and in conjunction with this mode changeover, the correction targets are also selectively changed in groups of three. In addition, as mentioned above, the correction targets selected in groups of three for each mode are the left and right rotation of Reuse 2 or the lamp lighting switch that also serves as a correction correction switch.
It can be easily corrected by pressing S ₂ .

In the above embodiment, it is clear that if it is desired to change only the display mode of the watch, it is sufficient to operate the mode changeover switch _S1 while keeping the watch 2 in the normal position 2a.

As described above, according to the present invention, the second switch is configured to be interlocked with the rotational operation of the reuse in accordance with the state of the first switch interlocked with the axial position of the reuse and the mode switching means. Since the input functions of both the switch and the push-button type third switch are simultaneously controlled, once the time mode is set to be adjustable, the axial position of the watch cannot be changed. Or, without requiring a new mode switching operation to change the correction target, hours and minutes can be corrected by rotating the reuse, and seconds can be reset to zero by operating a push button. , each can be executed immediately, and once the state in which the alarm mode can be corrected is set, the reuse can be executed without changing the axial position of the reuse or changing the mode to change the correction target. By operating the rotation, the hours and minutes of the alarm set time can be corrected, and by operating the push button, the alarm function can be turned on or off. In other words, in the present invention, when adjusting the hours and minutes of the time and the alarm set time, which are likely to involve relatively large corrections, it is possible to adjust the hours and minutes by rotating the reuse, which allows correction of large values relatively easily. Adjustment of the seconds and ON/OFF of the alarm function, which can be performed by simply adjusting the return to zero, is a simple operation, so it is performed by operating a push button. Since the correction function is divided according to the suitability of the operation mode, while maintaining a unified operation mode in time mode and alarm mode,
Moreover, it is possible to easily and quickly perform correction input. Furthermore, according to the state of the first switch that is linked to the axial position of the crown, the input functions of not only the second switch that is linked to the rotation of the crown but also the push button type third switch are controlled simultaneously. Due to the basic structure of the present invention, if the reuse is set to the normal position,
In both time mode and alarm mode, correction input is prohibited regardless of whether the reuse is rotated or the push button is operated, so it is also possible to prevent incorrect correction input due to erroneous operation in normal mode. It is now possible to do both. In addition, if the lamp lighting switch _S2 is also used as a correction auxiliary switch as in the above-mentioned embodiment,
It is also possible to suppress an increase in the number of externally operated switches.

Further, in the above-mentioned embodiment, the display is also changed by the mode changeover switch, but it is also possible to change only the object to be corrected by the mode changeover switch. Further, in the above-mentioned embodiment, the hour or minute, month or date is adjusted independently depending on the rotation direction of the lieuse in each mode. It is also possible to modify the date and time as a single modification target, non-independently. In that case,
It is also possible to control the frequency of the correction signal by the rotation angle or rotation speed of the reuse, or to selectively control additive correction or subtraction correction by the rotation direction.

Furthermore, in the above-described embodiment, the single mode changeover switch _S1 is configured to cyclically switch between the time display mode, the calendar display mode, and the alarm display mode. It is also possible to separately provide a switch and a switch for switching to the alarm display mode. That is, a plurality of mode changeover switches may be provided.
