Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a correction device for, for example, an electronic timepiece.

Conventionally, for example, most of the time adjustments in electronic digital watches have been by push button methods, such as those that advance one step with a single switch operation, and those that fast forward at a constant speed by pressing and holding the button. . In the former case, for example, adjusting the minute digits requires pressing the button up to 59 times, which is cumbersome; in the latter case, for example, in order to fast forward every second, the switch must be pressed for up to 59 seconds. Moreover, when the feed speed is increased, the predetermined time is passed quickly.

SUMMARY OF THE INVENTION Therefore, the present invention provides a correction device for an electronic timepiece that generates a different number of pulses depending on the operating speed of a rotary switch and changes the number of pulses depending on the time mode.

An embodiment of the present invention will be described below based on the drawings.

In FIG. 1, S is a rotary switch, and a knob 1 is fixed to a shaft 2. Click grooves 3 and 4 are formed on the shaft 2, and a rotating body 5 is fixed thereto, and electrodes 6...6 are formed on the rotating body 5. The electrodes 6...6 are drawn out to the shaft 2 via the lead electrode 7, and are connected to a power source (not shown) from the terminal _P1 via a contact piece 8 in contact with the shaft 2. Reference numerals 9 and 10 designate contact pieces, the tips of each of which are disposed slightly shifted in the rotational direction of the rotating body 5 and can be brought into contact with and separated from the electrodes 6 . . . 6 .
The contact pieces 9 and 10 are respectively grounded from terminals P ₂ and P ₃ via resistors. Reference numeral 11 denotes a switch, which is closed by the movement of the rotating body 5 in the axial direction. Its contact piece 11a is connected to the power source via the terminal _P4 , and the contact 11b is connected to the resistor from the terminal _P5 . It is grounded via.

In FIG. 2, 12 is a crystal oscillator, 13 is a frequency divider, 14 is a counter for counting seconds, 15 is an up-down counter for counting minutes and hours, 16 is an up-down counter for counting dates and months, and 17 is an up-down counter for counting minutes and hours. An up-down counter 18 is used to measure the day of the week. 19 is a counter, and when the count value is 1, 4 and 8, the terminals v ₁ and v ₂ are connected respectively.
and produces an output "1" at _v3 . 20 to 25 are flip-flop circuits. 26 is a time mode selection circuit, which generates "1" at the hour and minute mode terminal D and "1" at the day of the week mode terminal W as the switch 27 is switched to terminals a, b, and c. . 28 is a display device, 29
50 are gate circuits, and 51 to 53 are chattering removal circuits. 54 is a differential circuit, 55 to 57 are inverters, and 58 and 59 are resistors. 60,6
Reference numeral 1 designates a switch, which is composed of a contact piece 9 and an electrode 6 . . . 6 as shown in FIG. 1, and a contact piece 10 and an electrode 6 . A switch 62 is composed of a contact piece 11a and a contact point 11b.

Next, the operation will be explained. In the case of time adjustment, pull out the knob 1 shown in the first figure one step, close the switch 62 shown in FIG.
- inputs of 9, 33, and 37 are held at "1". Further, the switch 27 is connected to the terminal a to set the terminal M of the time mode selection circuit 26 to "1". As a result, the output of the gate circuit 29 becomes "1", the counter 14 is reset, and the gate circuit 30 is closed. Then, move the knob 1 shown in the first diagram in the direction of the arrow A.
When the switches 60 and 61 are rotated to
AB pulse is generated. Therefore, the output q of the flip-flop circuit 20 is inverted to "1", and the counters 15-17 are held in the up-down counting mode. On the other hand, the open/close output of the switch 61 is supplied to the flip-flop circuit 21. Here, since the flip-flop circuit 21 is supplied with a high frequency pulse, for example, a 512 Hz pulse, from the terminal t of the frequency divider 13, the pulse shown in FIG. 3C is generated at the output Q of the flip-flop circuit 21. Further, the pulses shown in FIG. 3D and E are generated at the outputs Q of the flip-flop circuits 22 and 23, respectively. Therefore, the pulse shown in FIG. 3F is generated from the gate circuit 42, and the flip-flop circuit 24 is set by its differential output. Its output Q opens gate circuit 45 through which the output pulse from frequency divider 13 passes to produce the pulse of FIG. 3I. This is supplied to the counter 19 and also to the counter 15 via gate circuits 31 and 32, and its contents are advanced. Now, when the counter 19 counts 1, "1" is generated at the output terminal _v1 , and the - input of the gate circuit 46 is held at "1". Here, if the output Q of the flip-flop circuit 25 is held at "1", the output of the gate circuit 46 becomes "1", and the flip-flop circuit 24 is reset via the gate circuit 47. Therefore, the gate circuit 45 is closed and the counter 19 is reset.

Now, when the flip-flop circuits 22 and 23 stop producing the pulses shown in FIG. 3D and 3E, the gate circuit 43 generates the pulses shown in FIG. 3G. This pulse causes the counter 18 and the flip-flop circuit 2 to
5 is reset. On the other hand, when the pulse generated at the output Q of the flip-flop circuit 23 stops, the output of the gate circuit 44 is inverted to "1" as shown in FIG. 3H, and the gate circuit 41 is opened. Therefore, a 512 Hz pulse from the frequency divider 13 is supplied to the counter 18 via the gate circuit 41. This determines the time from when the pulse at the output Q of the flip-flop circuit 23 stops until the next pulse occurs, that is, after the contact piece 9 in FIG. The time until it contacts the electrode 6 is counted. This makes the first
The rotational speed of the knob 1 in the figure is detected. In this example, it is assumed that the setting is such that when the counter 18 counts approximately 0.5 seconds or more, an output "1" is generated at the terminal 18a.

Therefore, for example, if the switch 61 is opened or closed at a low speed of 0.5 seconds or more, the terminal 18a of the counter 18
produces an output “1” in the flip-flop circuit 25.
The output Q of is inverted to "1" and the gate circuit 46 is opened. In this state, when the pulse shown in FIG. 3F is generated from the gate circuit 42, the flip-flop circuit 2
4 is set and gate circuit 45 is opened. The pulses from frequency divider 13 are then supplied to counter 19 and counter 15. When the counter 19 counts "1", a "1" is generated at the output terminal _v1 as described above, the flip-flop circuit 24 is reset, and the gate circuit 45 is closed. Thus, when the switch is opened and closed at a low speed, one pulse is supplied to the counter 15 each time the switch is opened and closed.

Next, when the switch 61 is opened and closed at a high speed of 0.5 seconds or less, the terminal 18a of the counter 18 remains at "0", so the output Q of the flip-flop circuit 25 remains at "0". Therefore, each inhibit input of gate circuits 49 and 50 is "0",
Also, since the input M is "1", the gate circuit 50
will be held. Therefore, output “1” to the gate circuit 42
When this occurs, flip-flop circuit 24 is set, gate circuit 45 is opened, and pulses are supplied from frequency divider 13 to counters 15 and 19.
When the counter 19 counts 8, “1” is applied to the terminal _v3.
occurs, resets flip-flop circuit 24 via gate circuits 50 and 47, and closes gate circuit 45. During this time, 8 pulses are also supplied to the counter 15 and the count is advanced by 8. In this way, at high speed rotation, each time the switch is opened and closed, 8
A pulse is provided to counter 15.

Next, a case will be described in which the date and month counters 16 are corrected. Terminal b is set by switch 27.
is selected and the output D of the mode selection circuit 26 is set to “1”.
to be reversed. As a result, the output of the gate circuit 33 is inverted to "1", the gate circuit 34 is closed, and the gate circuit 35 is opened. Therefore, when the rotary switch S is rotated at a low speed, one pulse is supplied to the counter 16 each time the switch is opened or closed, as described above.
Also, when it rotates at high speed, the gate circuit 49 is opened and when the counter 19 counts 4 pulses,
"1" is generated at the terminal _v2 , and the counting of the counter 19 is stopped. Therefore, four pulses are generated each time the switch is opened or closed.

To correct the day of the week, connect the switch 27 to the terminal C and set the output terminal W of the mode selection circuit 26 to "1".
to be reversed. As a result, the gate circuit 37 is opened, and furthermore, the output of the gate circuit 48 is held at "1", and the gate circuit 46 is opened. Therefore,
When the manual switch is rotated, regardless of its speed, one pulse is supplied to the counter 17 via the gate circuits 39, 40 for each opening and closing of the switch.
Therefore, the day of the week counter 7 is incremented by a pulse proportional to the rotational speed of the switch. In the case of the day of the week, it takes 7 pulses to return to the original day of the week, so high-speed pulses are not required, so pulses are generated according to manual operation.

In the next embodiment, one pulse is initially generated regardless of the rotational speed of the manual switch.

FIG. 4 mainly shows the changed circuit within the broken line K in FIG. 63 to 67 are gate circuits, and the same reference numerals as in FIG. 2 indicate the same functional elements.
Note that the terminal _v1 of the counter 19 is omitted. In the figure, when the output W is "1" and the flip-flop is rotating at a low speed, that is, when the output terminal Q of the flip-flop circuit 25 is "1", the gate circuit 65 is not opened, so the flip-flop circuit 24 is not set, and the gate circuit The differential circuit 5 is connected to the output terminal u of 63.
Only an output of 4 occurs and the selected counter is incremented by 1. When the output W is "0" and the rotation is at high speed, that is, when the output terminal Q of the flip-flop circuit 25 is "0", the gate circuit 65 is opened and an output is generated from the differentiating circuit 54, as described above. The pulses supplied to the terminal t pass through the gate circuits 45, 64, and 63, and a number of pulses corresponding to the mode are obtained.

As described in detail above, the present invention converts the switching pulses generated by manual rotation into different numbers of pulses for various time modes. Therefore, in an electronic watch equipped with a display device for the date, month, day of the week, etc., even if the rotation speed is the same, when adjusting the time, the number of pulses is increased, and when adjusting the day of the week, it takes 7 pulses to return to the initial day of the week. You can freely set the correction speed according to the correction width of the time mode, such as by setting the number of pulses to a small number or to an intermediate number for the date.
