Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an electronic analog display timepiece, and more particularly to an improved electronic analog display timepiece that allows easy adjustment of the indicated time or alarm setting time.

An electronic analog display in which electronic display elements such as LCD and ECD are arranged at equal intervals on the clock display surface to imitate analog time pointers, and only specific elements selected from these display segments are lit to provide an analog display. Timepieces are well known and it is possible to obtain an electronic timepiece without moving parts. Normally, 60 of the display segments are arranged circumferentially at one-minute intervals on the clock face, and each element is divided into at least two parts in the radial direction, so that the long and short hands of a conventional mechanical watch can be divided into two segments. Identification is achieved by varying the length of the radially illuminated segments. These electronic analog display watches have the advantage of providing a smaller, particularly thinner watch than conventional watches with mechanically rotating hands due to the combination of integrated small electronic circuits and thin plate-like display surfaces. This makes it possible to provide an easy-to-read clock with a significantly enlarged effective area of the display surface, especially for table-top clocks and the like.

However, even with this type of clock, conventional devices require a mechanical correction mechanism to correct the indicated time or alarm setting time.
Normally, incremental feed corrections were made by push button switches. That is, this conventional device has a structure in which a predetermined correction pulse is supplied to the clock circuit each time or during the on-operation of the push button switch, whereby the current time is corrected in a fast-forward manner. Therefore, with this conventional device, if the interval between the current time and the desired correction time is large, the correction operation requires a significantly long time, and since it is a forward correction, if the correction time passes the desired time, It was necessary to re-correct for 12 hours, and there was a problem with poor operability.

Furthermore, if the corrected time is incorrect, it is necessary to clear the incorrect corrected time, and with the correction mechanism of conventional devices, the corrected time cannot be changed unless extremely complicated operations are performed with special corrections in mind, such as changing the operation mode. The drawback was that it could not be cleared.

In addition, as a conventional correction device, a device has been proposed in which a contact disk for generating correction pulses is provided on a correction shaft that is operated externally, and quick correction is made by rotating the correction shaft. When the interval between the time and the correction time is large, it is basically impossible to eliminate the need for correction operations and re-corrections that take a long time as described above, and an improvement has been desired.

The present invention has been made in view of the above-mentioned conventional problems, and its purpose is to be able to specify a desired correction time by touching a correction touch switch provided on a watch, regardless of the current time.
In addition, the corrected time can be indicated very easily on the time display board, and furthermore, an improved electronic device allows you to easily clear the incorrect corrected time using a very natural operation and a correction touch switch. Our goal is to provide analog display clocks.

Preferred embodiments of the present invention will be described below based on the drawings.

FIG. 1 shows an electronic time display suitable for the present invention, and the display surface 10 includes a plurality of electronic display segments consisting of an LCD or an ECD. The display segments of the embodiment include 60 outer peripheral display segments 12-1 to 12-60 arranged at equal intervals along the circumferential direction of the display surface 10, and are provided separately from these display segments 12. It includes inner peripheral side display segments 14-1 to 14-60. Both of these display segments 12 and 14 perform a display that resembles the long hand and short hand of a normal mechanical watch, and both segments 12 and 14 are arranged in a row.
When only the inner display segment 14 lights up at the same time, it indicates the position of the long hand, and when only the inner display segment 14 lights up, it indicates the position of the short hand.
These display segments 12 and 14 are substantially transparent in their unlit state, and when they are turned on, they can indicate the time such as "10:10" in FIG.

The display surface 10 shown in FIG. 1 is attached to an alarm clock, and an embodiment in which the set time of the alarm can be easily modified according to the present invention will be described below.

A feature of the present invention is that a correction touch switch for adjusting the time is provided on the display surface 10, and FIG. 2 shows the arrangement of this correction touch switch. On the outer surface of the display surface 10, in this embodiment, on the surface of the protective glass, 12 correction touch switches 16 are applied at 5 minute intervals.
1 to 16-12 are arranged in a circumferential manner, and these are provided at overlapping positions near the connecting portions of the display segments 12 and 14 every five minutes. Each touch switch 16 consists of a substantially transparent electrode, and the user can touch the touch switch 16 with a finger or the like.
By touching it, it is possible to obtain an electrical ON operation signal.

In the present invention, a correction mode changeover switch (not shown) is provided in order to switch from the time instruction mode shown in FIG. It can be formed from a touch switch or a mechanical switch provided on the other side. When such a mode changeover switch is operated, the clock circuit, which will be described later, enters the alarm setting time adjustment state, and the display screen 10 shows the position of the adjustment touch switch 16 at this time as shown in FIG. The position of the touch switch 16 is displayed as shown. In the embodiment, the position display is on the outer and inner display segments 1 of the position where the touch switch 16 is provided.
This is done by lighting up all 2 and 14,
In reality, a touch switch 16 is provided near the joint between these two segments 12 and 14, but the operator can point an arbitrarily selected position along the display from among the display segment positions shown in FIG. By tracing the touch switch 16, it is possible to electrically turn on the touch switch 16.

In the illustrated embodiment, the alarm setting time is corrected by turning on the correction touch switch 16 twice, and the first on operation corrects the "alarm time" time, which will be described later in the circuit settings. At the same time as the time adjustment is completed, on the display screen 10, as shown in FIG. 4, any of the outer peripheral display segments 12 that have been turned on goes out, and the corrected alarm time is displayed on the display screen 10.

As is clear from FIG. 4, it is understood that in this case, the hour digit of the alarm setting time is "7 o'clock".

This is followed by the next touch switch operation, for example, when the minute time is corrected to ``00 minutes'', the 5th touch switch is
Both display segments 12, 14 as shown
Only the "00" position remains, and after all the above corrections are completed, the corrected alarm setting time, ie, "7:00" is displayed on the display screen 10 as shown in FIG. The operator can confirm the alarm correction time on the display screen 10.

Of course, if the corrected minute time is not on the hour, the final corrected time display will be corrected to the correct time position from the hour that occurs when the "alarm hour" time is corrected, i.e. if the corrected time is "7:30". ”, the display segment that displays the hour is adjusted to a position moved by 30 minutes.

As described above, according to the present invention, the time can be adjusted very easily using the touch switch 16 on the display surface 10.

Next, a description will be given of an operation to be performed when the corrected time is incorrect and the corrected time is cleared.

If the hour digit "7 o'clock" of the corrected time is incorrect and you want to clear the hour digit "7 o'clock" of the corrected time,
In the present invention, it is sufficient to stroke the display surface 10 with a finger for a predetermined length or more, and a predetermined number or more of correction touch switches, in the embodiment, one as shown in FIG.

By turning on the five correction touch switches 7 in succession within a certain period of time, the erroneously corrected time digit "7 o'clock" is cleared, and the display segment 12 corresponding to the correction touch switch 16 is cleared. , 14 are lit to display the position of the correction touch switch 16. By this clearing operation, the display surface 10 is returned to the state before correction as shown in FIG. 7, so that correction can be made again.

Similarly, the hour digit "7 o'clock" and minute digit "00 minutes" of the corrected time are incorrect, and the hour digit "7 o'clock" of the corrected time is incorrect.
and if you want to clear the minute digit "00 minutes", press the 8th
As shown in the figure, 16-2, 16-3, 16-
Five correction touch switches 4, 16-5, and 16-6 are turned on continuously within a certain period of time.
As a result, the display surface 10 returns to the state before the correction shown in FIG. 7, and can be corrected again.

As explained above, according to the present invention, the time can be adjusted extremely easily using the touch switch 16 on the display surface 10, and furthermore, the incorrectly adjusted time can be easily cleared. The circuit configuration of a preferred embodiment of the electronic analog display timepiece according to the present invention that corrects the alarm setting time will be described with reference to FIGS. 9 and 10.

9 and 10, in order to display the current time, the clock circuit includes an oscillator 18 including a crystal oscillator, a frequency divider 20 that divides the frequency of this reference pulse, and counts the divided pulses every minute and every hour. It includes a minute counter 22 and an hour counter 24. The outputs of both counters 22 and 24 are supplied to an outer decoder 28 and an inner decoder 30 via a display switch 26. The output of each decoder 28, 30 is supplied to an outer driver 36 and an inner driver 38 via an OR gate group 32, an AND gate group 35, and an OR gate group 34, respectively.
The outer display segment 12 described above by 38
and supplies a display signal to the inner display segment 14. In FIG. 9, both display segments 12,
14 are 12 each required for alarm setting time display
Although only 3 segments are shown, drivers 36, 3
Of course, other display segments for time display are also connected to 8.

From the above configuration, in the normal current time display, the desired display segments 12 and 14 are lit in response to the current time signal counted by the minute counter 22 and the hour counter 24, as shown in FIG. The time is displayed.

The electronic analog display clock in this embodiment has an alarm mechanism and includes an alarm minute counter 40 and an alarm hour counter 42 to set a desired alarm time, and both counters 40 and 42 to confirm the alarm setting time. The output of is supplied to the display switch 26. Further, in order to perform a predetermined alarm action when the current time reaches the alarm setting time, the count contents of the minute counter 22 and hour counter 24 are compared with the contents of the alarm minute counter 40 and alarm hour counter 42 by a matching circuit 44. When the two match, the alarm 46 is activated. In order to switch the display between the current time and the alarm setting time using the display switch 26, the display switch 26 is supplied with a switching signal of the display switching FF 48, and the Q of the display switching FF 48 is supplied at the time of correction, which will be described later.
The output becomes "H" and the display switch 26 is switched from the normal current time display to the alarm setting time display.
The display switching FF 48 has a display reset switch 50.
is connected, and after the display correction is completed, the display switch 26 is returned to the normal current time display.

In order to correct the alarm setting time, both of the counters 40 and 42 are provided with an alarm minute preset circuit 52 and an alarm preset circuit 54, and the contents of each of the counters 40 and 42 are sent to these preset circuits 52 and 54. The corrected preset is then set.

The presetting of both of the preset circuits 52 and 54 is performed by turning on the correction touch switch 16 described above, and therefore the on operation signal of the correction touch switch 16 is sent to the AND gate group 56, the chattering prevention circuit 58, and the alarm decoder. 60 and an alarm decoder 62 to both preset circuits 52 and 54, and when the correction touch switch 16 is enabled and either switch 16 is touched by the operator's finger, the selected switch position is set. The corresponding alarm setting time is preset.

The present invention further changes the operation of the clock circuit and display surface from the normal current time mode to the correction mode.
In this embodiment, a mode changeover switch 64 is provided to switch to the alarm setting time correction mode, and the mode changeover circuit 66 is operated by the changeover switch 64, and the desired mode changeover effect is performed by the FFs 68 and 70. It will be done. That is, a signal 301 from the FF 68 is supplied to an OR gate 72 in the mode switching circuit 66, and a display switching trigger signal 302 from the OR gate 72 sets the display switching FF 48 to change the display switching device 26 to the normal current time display. Then, the display is switched to the alarm setting time display, and the contents of the alarm minute counter 40 and the alarm hour counter 42 are cleared to prepare for writing the corrected preset signals from the preset circuits 52 and 54. Furthermore, display switching trigger signal 3
02 is the FF76, 78 of the correction order setting circuit 74
Reset. Further, the FF 70 outputs a modified state holding signal 303, and the modified state holding signal 303
to open the AND gate 56 and enable the correction touch switch 16. Furthermore, the display switching trigger signal 302 is transmitted to the FF 80 in the mode switching circuit 66.
is supplied to the modified state holding signal 3 from FF80.
05 enables the alarm preset circuit 52 and the alarm preset circuit 54 to prepare for writing a correction signal from the correction touch switch 16, and also activates the outer circumferential decoder 28 and the inner circumferential decoder 3.
A display signal is supplied to all the OR gates 32 and 34 on the output side of 0, and all of the segments of the outer display segment 12 and the inner display segment 14 that display the position of the correction touch switch 16 are lit.

The correction order setting circuit 74 connects the FFs 76, 7
8 and gate groups 82, 84, 86, which determine the preset order of hours and minutes depending on the order in which the correction touch switch 16 is turned on, and in this embodiment, when the touch switch 16 is turned on for the first time. The hour and time are corrected, and the minute and time are also corrected by the next ON operation.

In the present invention, the correction touch switch 16
After the time is corrected by the first operation, the outer display segment 12 has a structure in which the segment corresponding to the corrected time goes out in order to display this corrected time. On the input side of 36, there is the above-mentioned AND gate group 35.
are provided, and these AND gate groups 35
Normally, a gate-on signal is supplied from the FF group 88, but when the touch switch 16 is turned on for the first time, this on-operation output is supplied from the chattering prevention circuit 58 to the FF group 88, thereby causing a predetermined AND By closing the gate group 35, a desired outer peripheral display segment 12 can be turned off. When the correction touch switch 16 is operated, this operation output is indirectly supplied from the OR gate 90 to the correction order setting circuit 74, and a different signal is output each time the correction touch switch 16 is operated in a predetermined order. Correction order setting circuit 74
From then on, the alarm preset circuit 54 is enabled by the signal 310 from the gate 82, and the signal 311 is output by the next operation of the correction touch switch 16, whereby the alarm preset circuit 52 is enabled. becomes. After the hours and minutes have been preset, the output 312 from the correction order setting circuit 74 becomes "H" and is output to the one-shot circuit 92, thereby resetting the correction circuit. That is, the output signal 313 of the one-shot circuit 92 resets the FF group 88 via the OR gate 93, and also resets the FF 80.

Furthermore, in the present invention, even if the corrected time is incorrect, it is possible to easily clear the incorrect corrected time, and the signal 306 caused by the operation of the correction touch switch 16 is the signal for the time correction operation. In order to determine whether the signal is for a clear operation, a clear circuit consisting of a time adjustment operation identification circuit 94, a stroking operation detection circuit 96, and a clear operation waiting circuit 98 is provided, as shown in FIG. There is. This clear circuit will be explained below.

In the time adjustment operation identification circuit 94, the signal 30
6 and the clock pulse train are supplied to an AND gate 100, which supplies the clock pulse train to the counter 102 only when the signal 306 is "H". The counter 102 counts the number of pulses of the supplied clock pulse train, and supplies a signal 307 to the FF 104 only when a predetermined number of pulses, for example, 10 or more pulses have been counted.
Then, the FF 104 supplies a modified order setting signal 308 to the modified order setting circuit 74 based on the signal 307. As described above, the time adjustment operation identification circuit 94 determines that the signal 306 is a time adjustment operation signal. Further, an inverter 106 is provided in the time adjustment operation identification circuit 94, and when the signal 306 changes from "H" to "L", the inverter 106 controls the counter 102 and
Reset FF104.

Next, in the stroking operation detection circuit 96, the signal 3
06 is supplied to the counter 108, and the counter 10
8 counts the number of pulses of the signal 306 and outputs a clear signal 309 only when a predetermined number of pulses is counted. That is, when a predetermined number, for example, five or more correction touch switches 16 are stroked continuously within a certain period of time, the signal 306 becomes 5.
The counter 108 outputs a clear signal 309 because the pulse has more than "H". In response to this clear signal 309, the corrected time is cleared, and the display segments 12 and 14 corresponding to the correction touch switch 16 are lit to display the position of the correction touch switch 16.
Re-correction is possible.

As described above, the stroking operation detection circuit 96 determines that the signal 306 is a clear operation signal. Further, an OR gate 110 is provided in the stroking operation detection circuit 96, and a correction order setting signal 308 from the FF 104 in the time correction operation identification circuit 94 or an FF in the mode switching circuit 66 is provided.
Signal 304 from 70 is provided to counter 108 via OR gate 110 and
Reset.

Next, in the clear operation waiting circuit 98, the FF
112 is supplied with a one shot output signal 313 from the one shot circuit 92. Further, a clock pulse train is supplied to the counter 114, and a signal 314 from the FF 112 and a signal 306 from the OR gate 90 are supplied to the counter 114 via the OR gate 116 to reset the counter 114. After this reset action, counter 1
14 counts a predetermined number of pulses of the clock pulse train, the counter 114 outputs a signal 315, and the signal 315 causes the mode switching circuit 66 to
When the FF 70 is reset, the FF 112 in the clear operation waiting circuit 98 is also reset.

The embodiment of the present invention has the above configuration, and its operation will be explained in detail below using the display state of the display surface 10 described above and the time charts shown in FIGS. 11, 12, and 13.

FIG. 11 shows a time chart when the corrected time is correct and there is no need to clear the corrected time.

At time _t1 in FIG. 11 from the normal current time display state shown in FIG.
When turned on, the switching signal 300 causes the signal 30 from the output Q of the FF 68 of the mode switching circuit 66 to be turned on.
1 becomes "H", and the display switching trigger signal 302 also becomes "H". And as a result, display switching FF4
8 is set, and the mode switching signal of the FF 48 becomes "H", so that the display switching device 26 switches to the first
You can switch from the current time display to the alarm setting time display as shown in the figure. At the same time, the contents of the alarm minute counter 40 and the alarm hour counter 42 are cleared, preparations are made to write a correction preset signal from the correction touch switch 16, and FFs 76 and 78 of the correction order setting circuit 74 are reset, thereby resetting the signal. 310 becomes "H", the alarm preset circuit 54 is enabled. Furthermore, the output 312 of the modification order setting circuit 74 is "L".
This becomes a level (hereinafter simply referred to as "L") signal, and the one-shot circuit 92 enters a rest state. At this time FF
Since the groups 88 are all in the reset state, the AND gate groups 35 on the input side of the outer peripheral driver 36 are all in the open state.

Next, at time _t2 , when the mode changeover switch 64 is turned off, the signal 301 from the FF 68 becomes "L", and the corrected state holding signal 303 from the next stage FF 70 becomes "H". The correction state hold signal 303 opens the AND gate group 56 on the output side of the correction touch switch 16 to enable the correction touch switch 16. Further, since the signal 301 becomes "L", the display switching trigger signal 302 also becomes "L", and the correction state holding signal 305 of the FF80
becomes "H". This modified state holding signal 305 enables the alarm preset circuits 52 and 54, and furthermore, the modified state holding signal 305 supplies a display signal to the OR gates 32 and 34 provided on the output sides of both decoders 28 and 30. As a result, the outer display segment 12 and the inner display segment 14 provided corresponding to the correction touch switch 16 are all turned on, and the alarm setting time correction display and correction touch switch 16 shown in FIG.
The position will be displayed.

At time _t3 , the operator's finger traces the touch switch 16-7 indicating "7 o'clock" selected from the correction touch switches 16 in order to correct the alarm setting time, and as a result, the ON operation signal is activated. When output, the chattering prevention circuit 5
From 8, the time correction signal 306a becomes "H", and at this time, the correction signal is preset from the alarm decoder 62 to the alarm preset circuit 54, its contents are written to the alarm counter 42, and the alarm time is corrected. Complete. Then, the time correction signal 306a sets FF88-7, and as a result, the output of FF88-7 becomes "L", which is supplied to the corresponding AND gate 35-7, closing the AND gate 35-7, and as a result, The outer display segment 12-7 goes out, and as shown in FIG. 4, it is displayed on the display surface 10 that the alarm time has been corrected to "7 o'clock."

The time adjustment signal 306a is supplied as a signal 306 from the OR gate 90 to the time adjustment operation identification circuit 94 and the stroke operation detection circuit 96. In the time adjustment operation identification circuit 94, the counter 102 is
A predetermined number of pulses in the clock pulse train from time _t3 ,
For example, when 10 or more pulses are counted, that is, at time t ₄ , the signal 307 is set to "H", thereby the signal 308 of the FF 104 becomes "H", and the signal 308 is supplied to the correction order setting circuit 74 . Then, when the signal 306 becomes "H" at time _t3 , the inverter 106 becomes "L", and when the tracing operation of the correction touch switch 16-7 is completed at time _t5 , the signal 306 becomes "L".
Inverter 106 outputs "H" and counter 1
02 and FF104. For this reason,
At time _t5 , the modification order setting signal 308 becomes "L", thereby causing the modification order setting circuit 7
4 increments by "1", resulting in signal 310 being "L"
The signal 311 also switches to "H". Therefore, the alarm preset circuit 54 is disabled, while the alarm preset circuit 52 is enabled.

In addition, in the stroking operation detection circuit 96, the counter 108 counts the number of pulses of the signal 306 at time _t3 .
The clear signal 309 of No. 8 does not go to "H" but maintains "L". Therefore, the corrected time "7 o'clock" is never cleared. Then, at time _t4 , when the modified order setting signal 308 of the FF 104 becomes "H", the modified order setting signal 308 is supplied to the counter 108 via the OR gate 110, and the counter 108 is reset.

Next, at time t ₆ , the correction touch switch 1 is
When 6-12 is traced and the alarm minute time "00 minutes" is corrected, the chattering prevention circuit 5 is activated in response to the correction touch switch 16-12.
From 8 onwards, the minute correction signal 306b becomes "H", which is supplied to the alarm minute preset circuit 52 via the alarm minute decoder 60, and the preset to "00 minutes" is performed, and the contents of the alarm minute counter 40 become "00 minutes". ” is corrected.

Then, by the same action as the time adjustment described above, at time _t7 , the adjustment touch switch 16-12
When the tracing operation is completed, the minute correction signal 306b becomes "L", the result signal 308 becomes "L", and as a result, the output 311 of the correction order setting circuit 74
The signal 312 also becomes "L" and the alarm preset circuit 52 is disabled, while the signal 312 changes to "H". The signal 312 drives the one-shot circuit 92, and its one-shot output 313 drives the FF group 8.
8 and FF80 are reset. Therefore, the AND gate group 35 on the input side of the outer peripheral driver 36
are all open. In addition, the one shot output 313 is output from the FF112 in the clear operation waiting circuit 98.
At time _t8 when the one-shot output 313 becomes "L", the signal 314 of the FF 112 becomes "L", and the signal 314 is supplied to the counter 114 via the OR gate 116, and the signal 314 becomes "L".
Reset 4. Then, from time _t8 , the counter 114 counts the number of pulses in the clock pulse train, and when a predetermined number of pulses, for example, 40 or more pulses are counted, that is, at time _t9 , the counter 114 outputs the signal 315 as " H”. This signal 315 is the FF1 signal in the clear operation waiting circuit 98.
12, and the mode switching circuit 6.
Reset FF70 in 6. Here, the one shot output 313 is not immediately supplied to the FF 70 in the mode switching circuit 66 at time _t8 , but is supplied to the FF 70 via the clear operation waiting circuit 98.
In other words, the reason why the one-shot output 313 is supplied to the FF 70 after a certain period of time (time t ₉ ) has been taken into consideration is that an erroneous correction time clearing operation may be performed between times t ₈ and t ₉ . . And the time
At _t9 , the FF70 of the mode switching circuit 66 is reset, so that the modified state holding signal 303
becomes "L" and the correction touch switch 16 is disabled. Further, at time _t7 , due to the change of the modified state holding signal 305 to "L", all the lighting signals of the OR gates 32 and 34 on the output side of the outer circumferential decoder 28 and the inner circumferential decoder 30 become "L",
Each display segment 12, 14 has a peripheral decoder 28
The display contents are determined only by the internal circumferential decoder 30, and the display contents become the contents of the alarm minute counter 40 and the alarm hour counter 42 that have been changed by the above-mentioned correction action, and are as shown in FIG. The alarm setting time "7:00" is displayed. Furthermore, at time _t9 , the signal 304 is set to "L" by resetting the FF70.
The signal 304 becomes “H” from the stroking operation detection circuit 96 to the OR gate 110.
and resets the counter 108.

As a result of the above, at time _t9 , the operator confirms that the alarm setting time has been corrected to the desired time, and then turns on the display reset switch 50, resets the display switching FF 48, and turns on the display switching device 26. You can switch to the normal current time display.

As described above, according to the embodiments shown in FIGS. 9 and 10, after the correction mode is selected, the alarm time is corrected by operating the first correction touch switch 16, and then by operating the correction touch switch 16. The alarm minute and minute times can be corrected at , and the hour and minute correction times are clearly displayed on the display screen 10, and the correction can be made in an extremely short time. Further, the correction touch switch 16 is effective only when the correction mode is selected, and even if the display surface 10 is accidentally touched during normal current time display, it will not affect the current time display in any way.

Next, a case will be described in which the corrected time is incorrect and it is necessary to clear the incorrect corrected time.

In Figure 12, the corrected time and time are incorrect.
A time chart is shown in case it is necessary to clear an incorrect correction time.

At times t ₁ to _{t 5} of the time chart in FIG. 12, the same effect as at times t ₁ to t ₅ in the time chart of FIG. 11 is performed, and as shown in FIG. 4, the alarm time is "7". will be corrected at the time. but,
If the corrected time "7 o'clock" is incorrect and you want to correct the time to "8 o'clock", it is necessary to clear the incorrect corrected time "7 o'clock".

The present invention is characterized in that when a predetermined number of correction touch switches 16 (in the embodiment, five or more) are operated consecutively within a certain period of time, the corrected time is cleared. That is, as shown in FIG. 6, 16-3, 16-4,...
..., 16-7, when the five correction touch switches 16-7 are operated in succession, at times t ₆ to t ₇ in FIG.
At , signal 306 becomes a pulse with five "H"s. Therefore, the counter 108 in the stroking operation detection circuit 96 counts the number of five pulses of the signal 306, and the counter 108 outputs "H" of the clear signal 309 at time _t7 . In addition, 5
The signal 306 having 1 pulses is also supplied to the counter 102 in the time correction operation identification circuit 94, but since the duration of one pulse is short, the count of clock pulses does not reach the count up of the counter 102. , Therefore, the FF 104 does not supply the modified order setting signal 308 to the modified order setting circuit 74.

At time _t7 , the display switching trigger signal 302 of the OR gate 72 also becomes "H" due to the "H" of the clear signal 309, the display switching trigger signal 302 is supplied to the display switching FF 48, and as a result, the display switching FF 48 is set. When the mode switching signal of the FF 48 becomes "H", the display switching device 26 is switched from displaying the incorrectly corrected time to the alarm setting time as shown in FIG. At the same time, the alarm minute counter 40 and the alarm hour counter 42 are cleared of their erroneous contents, and preparations are made for writing a re-correction preset signal from the correction touch switch 16. In addition, a display switching trigger signal 302
is supplied to FFs 76 and 78 in the modification order setting circuit 74, and resets FFs 76 and FF 78. As a result, the signal 310 from the gate 82 changes from "L" to "H", and the signal 311 from the gate 84 changes from "L" to "H".
changes from "H" to "L". And signal 31
0 becomes "H", the alarm preset circuit 54 is enabled. Note that the output 312 of the gate 86 in the correction order setting circuit 74 is "L".
Therefore, the one-shot circuit 92 is in a rest state. However, a clear signal 309 of "H" from the counter 108 in the stroking operation detection circuit 96 is supplied to the OR gate 93, and a signal 316 is supplied from the OR gate 93 to the FF group 88. For this reason, F.F.
The groups 88 are all reset, and the AND gate group 3 on the input side of the outer driver 36
5 are all open.

As described above, by successively turning on the five correction touch switches 16 from time t ₆ to _{t 7} , the incorrect correction time "7 o'clock" is cleared, and the correct correction touch switch 16 is cleared. Display segments 12 and 14 light up, and display surface 1
0 is the state before correction as shown in FIG. That is, at time _t7 , the state is the same as that at time _t2 , and re-correction is possible.

Then, from time _t8 to _{time t15} , the same action as in the time chart of FIG. 11 is performed, and the alarm time is corrected to the correct alarm time.

The time chart in Figure 12 deals with the case where the corrected hour and time are incorrect, but in the time chart in Figure 13, the corrected minute time is incorrect, or the corrected hour and minute time are incorrect. This handles the case where it is necessary to clear incorrectly modified hours and minutes.

At times t ₁ to _{t 7} of the time chart in FIG. 13, the same effect as at times t ₁ to _{t 7} of the time chart in FIG. 11 is performed, and as shown in FIG. 00 minutes”. However, the corrected time "7:00" is incorrect and if you want to correct the time to "8:15", you need to clear the incorrect corrected time "7:00".

Therefore, from time _t9 to _t10 , as shown in FIG. 8, 16-2, 16-3,..., 16-6
Operate the five correction touch switches in succession. As a result, the same effect as at times t ₆ to _{t 7} in FIG. 12 is performed, and the incorrect corrected time "7:00" is corrected.
is cleared, and touch switch 16 for correction is cleared.
The corresponding display segments 12 and 14 light up,
The display surface 10 is in the state before correction as shown in FIG. That is, at time t ₁₀ , time t ₂
It will be in the same state as , and it will be possible to make corrections again. After time _t10 , the same action as in the time chart of FIG. 11 is performed, and the alarm time is corrected to the correct alarm time.

Note that at time _t8 of the time chart in FIG. 13, the counter 11 in the clear operation waiting circuit 98
4 is supplied with a signal 314 via an OR gate 116, and the counter 114 counts the number of pulses of the clock pulse train starting at time _t8 . A clearing operation is possible before the counter 114 reaches its count-up, and in FIG.
A clear operation is performed before the clear operation, that is, at time _t10 . As described above, the clear operation waiting circuit 98 allows the clear operation only within a certain period of time after minute and time correction.

As described above, according to the embodiment shown in FIGS. 9 and 10, the alarm setting time can be modified very easily by operating the modification touch switch 16.
Further, by continuously operating a predetermined number of correction touch switches 16, an erroneous alarm correction time can be easily cleared.

In the above-mentioned embodiment, the hour and time are corrected by the first ON operation of the correction touch switch 16, and the minutes and time are corrected by the next ON operation, but in the present invention, this is reversed and the first operation of the touch switch 16 corrects the minute and time. It is also possible to adjust the minute time and then the hour and time by the next touch switch operation, and a preferred embodiment for this purpose is the fourteenth and first touch switch operation.
This is shown in Figure 5.

Since FIGS. 14 and 15 are similar to FIGS. 9 and 10, the same members are given the same reference numerals and their explanations will be omitted.

A feature of this embodiment is that the output of the modification order setting circuit 74 sends the first signal 310 to the alarm minute preset circuit 52 and the second output 310 to the alarm preset circuit 52.
11 is supplied to the alarm preset circuit 54, and as a result, the first operation of the correction touch switch 16 that is made effective presets the alarm minute, and the next operation presets the alarm hour.

Further, an FF 118 is additionally set in the mode switching circuit 66, and this FF 118 causes all OR gate groups 32 on the outer circumferential side to output "H",
Further, the output 311 of the correction order setting circuit 74 causes all the OR gate groups 34 on the inner circumferential side to output "H".

As is clear from the above configuration, in this embodiment, when the correction mode is selected by the mode changeover switch 64, the FF118 of the mode changeover circuit 66
As a result, only the outer display segment 12 corresponding to the correction touch switch 16 lights up, and a desired minute correction time can be selected from among these segments.

Then, when the desired minute correction action is performed, for example, correction to "00 minutes", the FF 118 is reset by the output 311 of the correction order setting circuit 74, and as a result, the outer display segment 12 displays the corrected minute time. Only the position corresponding to is lit, and then the output 311 of the correction order setting circuit 74 becomes "H", so that all the OR gates 34 output "H",
As shown in FIG. 16, all of the inner display segments 14 are lit.

Next, when the correction touch switch 16 is turned on again to correct the time, the counter contents are corrected as described above, and the corrected alarm time is displayed as shown in FIG. .

According to the embodiment of FIGS. 14 and 15, the 9th and 10th
There is an advantage that the FF group 88 for opening the outer peripheral driver 36 shown in the figure is unnecessary.

As explained above, according to the present invention, it is possible to perform a correction operation extremely easily by simply touching the correction touch switch on the display screen to set the desired correction time, and at the time of correction, the position of the correction touch switch is The segment display allows the operator to select the desired correction time very clearly and easily, making it easy to perform corrective actions without any conventional mechanical rotation or push operations. It becomes possible to do so. Furthermore, according to the present invention, even when an incorrect time is input, if the user performs a natural action such as rubbing the incorrect time on the display screen to erase the incorrect time, the input time can be changed to the previous one. It can be easily cleared by the clearing action. and,
Such a clearing operation according to the present invention utilizes the very natural action that is normally taken when writing a wrong character, and can be done naturally without the user having to be aware of any special correction procedures. It is obtained as a motion, and has the advantage that there is no need to make incorrect corrections or think about the operating procedure when inputting or be confused. In particular, according to the present invention, it is possible to carry out simple corrections using extremely simple operating procedures without requiring any operation other than the touch switch for correction.

In the present invention, it is possible to correct not only the alarm time shown in the embodiment, but also the normal indicated time, and in the present invention, the correction touch switch is a substantially transparent touch switch provided on the outer surface of the display surface. Since it consists of a switch, it does not interfere with the display in the normal time display state, and has the advantage that the display surface can be set large, and there are no restrictions on the overall design of the timepiece.
