Abstract

PURPOSE:To enable the correction (alteration) of counting contents at a high speed by altering (correcting) the contents of a counter driven by a high frequency signal before the contents of a counter driven a low frequency signal under a control. CONSTITUTION:When manually correcting the display, initially minute with a short cycle alone is read out or minute and second performed simultaneously with a switch K1 and then, a switch K2 is closed resetting a second divide-by-60 counter 8, which is held at 00 second. Then, the counting of a minute divide- by-60 counter 9 is advanced quickly by a specified counting adjustment frequency of 1Hz or higher. Upon the end of the counting adjustment of the minute divide- to-60 counter 9, the switch K2 is turned OFF to reset from FF7 receiving a liquid crystal frequency (e.g. 32Hz) as input to the counter 8, the condition being held while the specified counting state of the minute is held. Subsequently, after the time signal or the like is sounded, with the closing of the switch K1, the time is set exactly keeping minute read out.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a counting device, and more particularly to a counting device that uses electrical means to change the contents of a count as a counting means used in an electronic watch or the like.

"Year""Month""Day""Day of the week""Hour""Minute"
In a multi-functional electronic watch that displays each block such as "seconds", all of these blocks are not displayed at the same time, but are usually displayed on an appropriate 5.5-digit or 3.5-digit display element. The display arrangement functions as a clock.

Furthermore, it is a well-known fact that unlike mechanical watches, all electronic automatic corrections make it easy to process month-ends and leap years. However, even if it is an electronic watch, when replacing the battery power supply, the above-mentioned seven blocks must not be manually corrected. The problem then is how to easily and quickly and accurately set these seven blocks to the correct time.

According to the conventional method, seven switches were required to manually modify these seven display blocks. However, this does not fully derive the benefits of electronic control. In particular, unless it can be quickly and accurately corrected (changed), it cannot be used for watches and the like that change over time.

SUMMARY OF THE INVENTION An object of the present invention is to provide a counting device that can quickly and accurately modify (change) counting contents.

The present invention has a plurality of counters driven by different frequency signals, and the content of the counter driven by a high frequency signal of the same frequency is higher than that of the counter driven by a lower frequency signal. The present invention is characterized in that it is provided with means for controlling so that it is changed (modified) first.

According to the present invention, among the counting contents that must be changed (corrected), by changing (correcting) the contents of the high frequency drive counter and putting it into operation, the counter with the largest correction error can be accurately corrected. The remaining low frequency drive counters can then be modified with some margin. Therefore, the correction error is extremely small, making it suitable for clocks where accuracy is required.

Examples of the present invention will be described in more detail below.

In ordinary electronic clocks, the synchronization time is short.
It is a block of "seconds". In other words, how to easily and quickly and accurately match blocks of short "seconds" to the correct second time. Therefore, in the display control method of the present invention, "seconds", "minutes", "hours", "day of the week",
"Sun", "Month".

The reading order of counting speed feed for each block in the "Year" group is performed from the one with the shortest synchronization of each block, that is, these 7
In the example of blocks, read out in the order of "seconds", "minutes", "hours", "day of the week", "day", "month", and "year", and then when adjusting the count of each block, start from the short synchronized block. Carry to a block with a long synchronization is not carried out, and the "second" or "
If you set each block of ``minutes'' to the correct second or minute time, then the ``hour'', which has a long synchronization, and even the ``-day'', ``day'', ``month'', and ``year'' blocks will be set to the correct seconds or minutes.
It is possible to perform extraction and count adjustment for each block.

Specifically, for example, when the first switch initially reads only the short "minute" of the K11 period from the normal state, or "minutes" and "seconds" at the same time, the second switch is turned on.
After resetting the sexagesimal counter for "seconds" and holding it at % 00 seconds, the count of the sexagesimal counter for "minutes" is set to IHzt.
Or, by turning the i-th switch "off" at the same time as the completion of the predetermined count adjustment of the sexagesimal counter for "minutes", the counting speed can be changed to the same wave number for the predetermined count adjustment that is earlier than I Fit. Reset and hold the sexagesimal counter for "seconds" from the flip-flop that inputs the liquid crystal drive frequency (the current electronic hour hand 12s2b is used) and hold the predetermined counting state for "minutes". be done. By turning on the first switch along with the time signal (via a time signal telephone, etc.), the time can be set to the hour while the minute is read out.

If fiz is the same wave number as the liquid crystal drive at ζ-, the accuracy of time adjustment in this case is 1/f seconds (1/32 Hz seconds in the above example).
becomes. At this time, if it is found that the deviation of several seconds from the control in the second block is caused by the manual adjustment,
Immediately, when the second switch is turned on again, the 60-way counter for "seconds" is reset, and the count of the sexagesimal kakunta for "minutes" can be quickly sent to the predetermined frequency for adjusting the count.

When the adjustment of the predetermined number of stitches of the sexagesimal caranta for "minutes" is completed, the second switch is turned "off" to make the same wave number of the LCD drive the same wave number as the input flip from 70 to 60 for "seconds".
Reset and hold the advance counter, and
A predetermined counting state of "minute" is held.

Turn on the time signal again by turning on the first switch along with the time signal! ) set to the hour with an accuracy of 1/f seconds. After that, all you have to do is adjust the clock to the current time and calendar in the order of ``hour,'' ``day of the week,''``day,''``month,'' and ``year,'' regardless of the time signal, making it extremely easy to operate and set with high precision.

As described above, (1) the reading order of the predetermined counting adjustment of each display block is read in the order of the shortest synchronization of each display block, and (2) the "second" or "minute" which is the shortest synchronization is captured, and the "minute" is read out. '' or ``seconds''``minutes'' is the first readout of the count adjustment, and the correction operation is performed twice while the ``minutes'' or ``seconds'' or ``minutes'' are read out. Match.

The greatest feature of this invention is that the person can do it.

In order to facilitate understanding of the present invention, the block diagram of FIG. 1 will be explained as an example. When the power is turned on, flip-flop 6 and Dll flip-flop 2 are automatically cleared, and each output (QIQ2
Suppose that Q3Q4Q5) are (o, o, o, o, o), respectively. At this time, the gates representing the output states of each of the seven flip-flops 21 to 25 of the D-type flip-flop 2 are set to 31.
shall be. The inputs of this gate 31 are qt and qs, and the logical product is used), state (0,0°0.0.0
) is detected. Applying a 1 to the switch at ζ~ applies the high level of the power supply to the clock inputs of the seven lip-flops 21-25. Each flip-flop operates when the input pulse changes from low level to high level, so the moment the switch is closed, the output Q5 of flip-flop 25
is inverted by the inverter 3, and the 7-rig 7μ tube 21
Because it is inserted into the D input of the flip-flop 21~
25 outputs (Qt , Q2 , QB s Q4 ,
QB) company, respectively (1, 0, 0, 0, 0) and ζ
Let 32 be the gate representing the output state of the scraps 21 to 25. Assuming that the inputs of this gate 32 are Ql and Q2, the state (1, 0, 0, 0, 0) is detected by ANDing them.

Hereinafter, as the switch Kl is repeatedly turned on and off, the output states of the shift flip 70 knobs 21 to 25 are changed to states 3, 4, etc. in Table 1.
It changes sequentially from 6 to 10. These states 3, 4.6~l
The gates representing O are 33,341.3 respectively! S~3
Used as 9. The power of each of these gates is 2 people.Gate 33
is Q2. QB, 341 is QB, Q4, 35 is Ql, Q
B, 36 is QllQ2, 3f is Q2. QB, 38 is Q
B, Q4, and 39 are taken as Q 4 and s Q s, and each logical product is used to detect each state. As shown in Table 1, the display blocks for the outputs of game consoles 31, 32, and 33 are "hours, minutes, and seconds," and "hours, minutes, days, and days of the week," respectively.

The year, month, date, and day of the week are read out and displayed.

The reading method for adjusting the count of each block is, for example, when the output of gate 3 is at a high level, "day" is specified, but other than "day", the light is turned off and only "a" is displayed.
If the normal display at the time of the high level output of the gate 32 is set to -, it will read out the hours, 2 minutes, 9 days, and the day of the week by blinking only the "day" at the same wave number faster than the frequency for adjusting the number of stitches. One possible method is to move the block "day" for which you want to adjust the count to the farthest left or right side.

Now, when the first switch is repeatedly turned on and off, when the output of the gate 341 reaches a high level, that is, the state is reached! If 14 hours, minutes and seconds are displayed and read out, if 2 is turned on in FIG. The other input of the gate 4 has the output ζ6 of the flop flop 6 inserted, and since it is cleared when the power is turned on, Ql is at a high level, so the flip flop 6 is triggered, and its output Q6. Q6 each inverts from (Oal) to (tso) and resets and holds the sexagesimal counter 8 for "seconds" by the Q6D output. In addition, in order to set the other end of the input of the gate 10 to a high level, the contact signal 2 of the switch is passed through the gate 11 and the count adjustment signal 2b is set to "minute".
The continuous transmission of the count of the sexagesimal counter 9 is adjusted. After completing the predetermined count, turn off the switch 2. When the switch 2 is turned off, one input of the gate 12 receives the high level output of Ql, and the low level signal of the gate 2 is inverted by the inverter 13 and the high level is input to the other input of the gate 12. Since it reaches the input, the seven flip-flops 7 from the flip-flop whose input is the same wave number as the liquid crystal driving frequency f to the tree-flop whose output is IHz are reset and held. Next, when the switch 1 in FIG. 1 is turned on along with the time signal, the output Q6 of the flip-flop 6 input to the gate 14 is at a high level as described above, so the high level of the contact signal 1 at the switch is 14. through 9
and reach gate 5. Therefore, the output (Ql, Ql) of the 7-lip flop 6 again changes from anti-EL (1°0) to (0,1).
Then, the hold on counters 7 and 8 is released, and the data is read at the correct time with an accuracy of 1/f seconds. At this time, D[
Each output state of flip 70 tube 2 is (1, 1, 1, 1,
0) That is, since it is in state 5 of Table 1, it is set aside for reading. In other words, since the low level signal of the output Q6 of the 7 lip-flop 6 is inserted into the 150 input, the gate 15 is closed and the switch 2 is set to the time signal. When the switch is not turned on, state 1a5 is skipped from state 4 in Table 1 and state 15 is closed, which is configured to become state 6. Therefore, state 5 is reached at the same time as 1 is closed in the switch. In other words, it is in the state of reading the above amount. At this point, if it is confirmed that there is a deviation of several seconds in the second block due to manual error, turn on the switch 2 in FIG. 1 again. The D-type flip-flop 2 is in state 5 of Table 1.
I), detect this state in Q4. If the output of gate 342 is performed by gate 342 with input Q5, the output of gate 342 will be at a high level KTo, ? Therefore, the output of gate 34 is at a high level. Therefore, gate 4 opens and triggers flop 6 through gate 5, which outputs 7 rip 70 flop 6 (Q6.
Q6).

(0,1) becomes (1,0) again. As before, the sexagesimal counter 8 for "seconds" is reset and held. Furthermore, the contact signal 2 to the switch makes the other input of the gate 10 high level, so the count adjustment signal 9, for example 2 Hz, passes through the gate 11 and continuously transmits the number of stitches of the sexagesimal counter/counter 9 for "minutes". Adjust. After completing the predetermined count, turn off the switch 2. Since the high level of the output Q6 of the 7-lip flop 6 is input to one input of the switch 12, the low level signal of 2 is inverted by the inverter 13 and the high level is sent to the gate 12. Since the input frequency reaches the other input, the flip-flop 70 from the flip-flop whose input frequency is the liquid crystal driving frequency f to the tri-tube flop whose output is l2 is reset and held. Next, when the first switch is turned on at the same time as the time signal, the 7-rippu H passes through the gate 14 as described above.
Trigger the y pro and output the flip-flop 6 (Q6.Q
6) The counters are reversed again and from 110) to the normal state (0, 1), the counters 7 and 8 are released from hold and are set at the correct time with an accuracy of 1/f seconds.

At this time, the D-type flip-flop 2 is in the state 6 of Table 1, which is the state in which the "hour" is read. If the initial time setting by setting the switch to 1 is successful, turning on the switch to 1 again causes the D-type flip-flop 2 to go into state 6 as described above, allowing it to read out the hour. "
The minutes and seconds matched exactly, so after the time signal, I slowly operated the switch to set the hour without worrying about the passage of time. Next, read out state 7 with switch Kl, operate switch 2 to set the day of the month, then read out state 8 of switch KIK, operate switch 2 to set "day", and press switch Kl again. Use switch 2 to read out state 9, set ``month'' by operating switch 2, read out state lO by operating switch 1, set ``year'' by operating switch 2, and finish. Furthermore, when switch Kl is turned on, the display returns to state 1, which is the normal display, and displays "hours,""minutes," and "seconds."

Here, the counters 7, 8 in FIG. counter 9
Although the explanation has been given using color/return as an example, it is of course possible to use a shift register.

In this way, the blocks for adjusting the specified number of stitches are read out in the order of shortest cycle, and the seconds and minutes with the shortest cycle are read out first. A feature of the present invention is that the operation is extremely quick and easy, and the time can be set with high precision using exactly the same method.
