Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a pointer display type electronic timepiece equipped with additional functions such as an alarm function.

In recent years, there has been a demand for electronic watches with pointer displays to be equipped with additional functions such as alarms, and in addition, the hands can be selectively switched between displaying the current time and displaying additional functions. An electronic timepiece with a pointer display that is configured so as to be used has also been realized.

However, switching the display of the guideline as described above,
In reality, this is done by moving the pointer at high speed using a high-speed drive of a step motor.
Conventionally, a pointer display type electronic watch that is configured so that the display of the hands can be switched cannot be added with a calendar display function. In other words, in a pointer display type electronic watch with a calendar display function, the calendar display member is moved by the driving force from the pointer wheel train, so the pointers are moved at high speed by switching the display. Then, depending on the time period of the hand movement for the switching, the calendar display member may be moved, and in this case, the calendar display will be out of order.

An object of the present invention is to realize a pointer display type electronic watch that is equipped with both additional functions such as an alarm and a calendar display function. To provide a pointer display type electronic timepiece with an additional function, which is designed to prevent even a calendar display member from being moved.

Hereinafter, the present invention will be explained in detail with reference to the drawings.

and a push-pull button 4 provided as a secondary external operating member. In addition to the normal position 3a, the reuse 3 is configured to be able to be set to a 1st pull position 3b and a 2nd pull position 3c, and the button 4 is set to a push-in position 4a and a pull-out position 4b. It is configured so that it can be set to The watch of this example is configured such that the watch 3 is set at the normal position 3a when the watch is normally carried, and in this state the hands 1 display the current time. Therefore, in the following description, the state when the reuse 3 is set at the normal position 3a will be referred to as the normal carrying state.

Next, FIG. 2 is a plan view showing the external appearance of the clock of this example in the alarm set time display state.

In the watch of this example, when the reuse 3 is set to the first pulled position 3b while the button 4 is in the pulled out position 4b, the hands 1 are controlled to be in the alarm set time display state. That is, in the watch of this example, when the button 4 is in the pulled-out position 4b and the reuse 3 is pulled out from the normal position 3a to the pulled-out position 3b, the pointer 1 is moved at high speed in the forward rotation direction F, and as a result, It is switched to the alarm set time display state. Also,
Reuse 3 from this alarm set time display state.
When the pointer 1 is returned to the normal position 3a again, the hand 1 is moved at high speed in the reverse direction B, and returns to the current time display state.

In addition, in the watch of this example, when the button 4 is set to the push-in position 4a and the reuse 3 is set to the 1st-pull position 3b, as will be described later,
The calendar is configured to be in a quick correction state, and by rotating the reuse 3 in this state, it is possible to correct the date on the date plate 2. However, even in the above-mentioned calendar quick adjustment state, the hand 1 is configured to maintain the current time display state.

In addition, in the watch of this example, regardless of the setting state of the button 4, the reuse 3 is at the 2nd pull position 3c.
When set to , the current time is controlled to be in the current time adjustment state, and if the reuse 3 is rotated in this state, the current time can be adjusted.

The output signal from the crystal oscillation circuit 5 is transmitted to a frequency dividing circuit 6.
After being frequency-divided into a relatively low-frequency signal, the signal is input to the motor drive signal forming circuit 8 and the counting processing circuit 14 via the hand movement control circuit 7. Further, the motor drive circuit 9 drives the step motor 10 in accordance with the signal supplied from the motor drive signal forming circuit 8. Note that the hand movement control circuit 7 transmits signals of any frequency from the frequency dividing circuit 6 into the motor drive signal forming circuit 8 or the counting processing circuit according to control signals from the switch input control circuit 13 and the counting processing circuit 14. By controlling which part of the needle 14 is supplied, it is possible to control the hand movement state (i.e., the drive of the step motor 10) when the pointer 1 is normally driven, when switching the display, and when correcting the display. It functions to control (state). Further, the switch input control circuit 13 outputs an output signal for controlling the hand movement control circuit 7 in accordance with an input from a switch block 12 operated by an external operating member block 11 consisting of the above-mentioned reuse 3, button 4, etc. It is intended to supply Further, the counting processing circuit 14 is configured to perform processing such as counting the signals supplied from the hand movement control circuit 7, thereby making it possible to determine whether the display switching is completed or when the alarm set time has been reached. , an alarm block 15 including an alarm element is connected to the output side of the counting processing circuit 14.

On the other hand, the step motor 10 drives a wheel train 16 including an hour hand wheel and a minute hand wheel to which the hour hand 1a and minute hand 1b constituting the pointer 1 are attached.
The driving force is transmitted through the calendar drive mechanism 17,

is configured so that it is in the ON state (closed state).

On the other hand, the motor drive signal forming circuit 8 has a forward rotation signal forming circuit 33 and a reverse rotation signal forming circuit 34. The step motor 10 is configured to be selectively driven in either the forward rotation direction or the reverse rotation direction depending on whether the reverse rotation drive signal 8b is output from the reverse rotation signal forming circuit 34 or the reverse rotation drive signal 8b is output from the reverse rotation signal forming circuit 34. There is.

Furthermore, the counting processing circuit 14 includes a current time counter 46, a hand position counter 47, and an alarm, which are provided to maintain the relative relationships among the current time, hand display time (hand position), and alarm set time.

It has two comparison circuits consisting of 0. In the timepiece of this example, as will be described later, during normal operation, the step motor 10 is configured to be driven one step at a time every minute, so that the pointer 1 completely changes in one day (24 hours). During the lap, 60×24
Since the step motor 10 is driven by =1440 pulses, each of the counters 46,
47 and 48 are both configured as 1440 decimal up counters.

FIG. 2 is a plan view and a cross-sectional view of main parts when the device is in a normal carrying state. 7 and 8 are a plan view and a cross-sectional view, respectively, showing the state of the main parts when the reuse 3 is set to the first-drawn position 3b.
As will be described later, this figure is a plan view showing an example of the operating state that occurs in the calendar drive mechanism 17 when the clock is returned from the alarm set time display state to the current time display state.

Further, FIGS. 10 to 13 show the calendar quick correction mechanism 18 and the calendar quick correction control mechanism 20.

FIG. 10 is a plan view showing when the watch 3 is set in the normal position 3a and the watch is in the normal carrying state, and FIG. 11 is a plan view when the button 4 is set in the pulled out position 4b. FIG. 4 is a plan view showing the state of the main parts when the watch 3 is set to the first gear position 3b (that is, when the watch is in the alarm set time display state). FIG. 12 also shows the main parts when the button 4 is set to the push-in position 4a and the reuse 3 is set to the 1st pull position 3b (that is, when the watch is in the calendar quick adjustment state). 13 is a plan view showing the state, and FIG. 13 is a sectional view thereof.

First, in FIGS. 5 to 9, 60 is a first operating shaft fixed to the reuse 3;
0 is equipped with a well-known suspension wheel 61, and is configured so that when the Reuse 3 is rotated, the suspension wheel 61 is also rotated. In addition, the head of a well-known mandrel lever 62 is engaged with a groove (small diameter part) formed in a part of the operation shaft 60, and the mandrel lever 62 moves the setting position of the reuse 3 in the axial direction. It is configured to rotate about the mandarin duck shaft 62a as the center of rotation in conjunction with the rotation.

On the other hand, the above-mentioned calendar drive mechanism 17
It is composed of a date wheel 64 and a second date wheel 65, and in the normal carrying state, the first date wheel 64 is connected to the hour wheel 63, which is part of the aforementioned wheel train 16.
It is configured to rotate once a day in response to the driving force transmitted from the Furthermore, the first day wheel 6
4 is normally carried, via the feed claw 64c formed at the tip of the elastic arm 64b,
The second date wheel 65 is configured to advance one tooth at a time during one rotation, and as a result, the second date wheel 65 advances the date plate 2 one tooth a day. Note that 64a and 65a are the rotation center axes of the first date wheel 64 and the second date wheel 65, respectively. Further, the first date wheel 64 is made of a synthetic resin material, and a regulated portion 64d that protrudes in the height direction of the regulating lever 66, which will be described later, is also formed on the lower surface side of the tip of the elastic arm portion 64b. has been done.

In addition, the date wheel regulating lever 66 functions as the calendar drive control mechanism 19 together with the mandrel lever 62, and an elongated hole 66b formed in a part thereof engages with a pin implanted in the mandrel lever 62. are doing. The regulation lever 66
When the reuse 3 is in the normal position 3a as shown in FIG. Even in such a state, as shown in FIG. 6, the first date wheel 64 is controlled by the regulation lever 66 in the normal carrying state because it does not come into contact with the regulated portion 64d. The driving force can be transmitted to the second date wheel 65 as described above without any interference.

On the other hand, when the reuse 3 is moved from the normal position 3a to the one-step pulled position 3b, the regulation lever 66 is
As shown in FIGS. 7 and 8, it rotates in the direction of arrow A about the shaft 66a in conjunction with the oscilloscope lever 62, and the regulating portion 66c is rotated around the rotation center shaft 64a of the first date wheel 64. will approach the direction of For this reason, the regulating portion 66c enters inside the original trajectory of the feed claw portion 64c, and the feed claw portion 64c has already reached the second date wheel 65.
, the regulating portion 66c also displaces the regulated portion 64d on the lower side of the feed claw portion 64c in the direction of the rotation center axis 64a, and the elastic arm portion 64
b is in a bent state, and the feed claw portion 64c is controlled to be in a state in which it is impossible to engage with the second date wheel 65. Furthermore, when the first date wheel 64 rotates in response to the driving force from the hour wheel 63 in this state, the regulated portion 64d on the lower surface side of the feed claw portion 64c approaches the second date wheel 65. As it moves forward, it comes into contact with the regulating part 66c, and eventually, as described above, the feed claw part 64c is displaced in the direction of the rotation center axis 64a while the elastic arm part 64b is bent, and the second day rotation is started. The control is made such that engagement with the wheel 65 is impossible. That is,
In any case, Tuse 3 is in position 3b with one step pulled.
In this state, the regulation lever 66 disconnects the transmission of driving force from the first date wheel 64 to the second date wheel 65.

Although not shown, when the reuse 3 is set to the second pull position 3c, the regulation lever 66 is in the same position as in FIG. The transmission of the driving force is not disconnected.

The quick correction transmission lever 67 and the quick correction lever 68 constitute the above-mentioned calendar quick correction mechanism 18, and 69 is a known jump control lever.

However, in FIGS. 5 to 9 above, all the members other than the oscillator lever 62 are arranged on the face of the dial side of the base plate etc.
Since only the above-mentioned safety lever 62 is disposed on the surface of the back cover side of the board, the safety lever 62 is
2 is illustrated by a two-dot chain line.

Next, in FIGS. 10 to 13, 70 is a second operating shaft fixed to the button 4, and a groove portion (small diameter portion) formed in a part of the operating shaft 70 has a switching lever 71. is engaged. The switching lever 71 constitutes the above-mentioned calendar quick correction control mechanism 20 together with the lever 73.
A part of it is provided with a protrusion 71d for controlling the cannula, and 2
It has two elongated holes 71a, 71b which are respectively engaged with two fixing pins 72a, 72b, and is configured to be able to move in parallel along the direction in which the two fixing pins 72a, 72b are arranged. ing.

Further, the cannula 73 is configured such that an elongated hole 73b formed in a part thereof engages with a dowel 62c formed in a part of the mandrel lever 62, and furthermore, the head part of the cannula 73 is formed in a groove part of the ratchet wheel 61. (small diameter part). A spring portion 73c is also formed in a part of the cannula 73, the tip of which is in contact with the fixing pin 74, so that the cannula 73
Because of the spring force of the spring portion 73c, it is always subjected to a rotational force in the direction of arrow C with the canopy shaft 73a as the rotation center. Furthermore, a regulated portion 73d bent vertically in the height direction of the switching lever 71 is also formed in a part of the cannula 73, so that control from the regulating lever 66 can also be received via the regulated portion 73d. It is configured.

On the other hand, when the switch lever 75 is rotated by the rotation of the reuse 3, the switch lever 75 rotates the switch cam portion 61a provided on the switch wheel 61.
7.
5b is an engaging portion with the cam portion 61a. The switch lever 75 also has a switch lever control spring 7.
6, and contact portions 75d provided corresponding to switch terminals d and e.
It has That is, the switch lever 75 and the switch terminals d and e constitute the above-mentioned switch _S2 , and when the reuse 3 is rotated in the right direction R by a predetermined angle, the cam portion 61a engages the engaging portion 75.
b, the switch lever 75 is rotated in the direction of arrow D about the shaft 75a, and the contact portion 7
5d is in contact with terminal d. Also, when the Reuse 3 is rotated by a predetermined angle in the left direction L,
The switch lever 75 is rotated in the direction of arrow E,
The contact portion 75d is in contact with the terminal e. In addition, when the reuse 3 is not operated as described above, the switch lever 75 is moved by the control spring 7.
5, the contact portion 75d is controlled to be in a neutral state in which it is not in contact with either terminal d or e, as shown in FIG. Further, when the rotation angle of the reuse 3 further exceeds the predetermined angle, the engaging portion 7 of the cam portion 61a
It is configured such that the engagement with 5b is released and the neutral state is temporarily returned.

On the other hand, the suspension wheel 61 also has a quick correction cam 61b for driving the above-mentioned quick correction transmission lever 67, and only in the calendar quick correction state shown in FIG. The cam 61b is configured to engage with an engagement pin 67b implanted in the quick correction transmission lever 67. Furthermore, the quick correction transmission lever 67 has two spring parts 67.
A quick correction lever drive section 67e is formed at the tip of the spring section 67c, and a plate-like member 77 is formed at the tip of the spring section 67d.
It is held in place by the notch. Further, the quick correction lever 68 has a quick correction claw 6 at the tip of the spring portion 68b for driving the teeth of the date plate 2.
It has 8c.

Note that a part of the mandrel lever 62 has a contact part 6.
2d is also formed, and the external contact portion 62d is in a state where it is not in contact with any of the switch terminals b and c when the sleeve 3 is set to the normal position 3a, and when the sleeve 3 is in the 1st pull position. When set to position 3b, only terminal b is connected.
Furthermore, when set to the two-stage pull-out position 3c, each terminal is configured to be in contact with only the terminal c. In other words, the above-mentioned switch is
This is why S ₁ is configured.

Note that in FIGS. 10 to 12 above, members other than the quick correction transmission lever 67, the quick correction lever 68, and the date plate 2 are arranged on the surface of the back cover side of the substrate such as the main plate. In contrast, both levers 6
7, 68 and the date plate 2 are disposed on the face of the board on the dial side, so both the levers 67,
68 and the date plate 2 are shown by two-dot chain lines. In addition, the well-known back press lever that engages with the rear lever 62 in order to stably hold the Reuse 3 at each setting position is omitted from the drawings for the sake of simplicity. Regarding FIG. 12, illustration of the switch lever 75 and control spring 76 is also omitted.

In addition, the above-mentioned Figures 5, 7, and 9 and Figures 10 to 12 are shown in order to make it easier to understand the mutual relationship of each member.
The plan view is shown as a model, assuming that it is viewed from the same direction.

Next, the operation of the timepiece of this example will be explained. However, the circuit shown in FIG. 4 operates with positive logic, and when simply written as H or L, it is assumed that the circuit is at the logical H level or L level, respectively.

First, as shown in FIG. 1, when the watch 3 is set at the normal position 3a and is normally carried, the watch is configured to display the current time. Switch S ₃ operated by button 4 turns the alarm function itself ON to OFF.
It is provided to control Switch S ₃
When the switch S 3 is turned OFF, the alarm function is also turned OFF, and when the switch S ₃ is turned ON, the alarm function is also turned ON.
When the oscilloscope lever 62 is not in contact with either terminal b or c, the AND circuit 4 is connected regardless of the state of the switch _S3 .
Since the output side of 1 is at L, the output sides of NOR circuit 35 and inverter 36 are at H.

Here, the fact that the hand 1 is displaying the current time means that the hand display time (hander position) matches the current time, that is, the content of the hand position counter 47 matches the content of the current time counter 46. However, when the contents of both counters match and the hand 1 is displaying the current time, the comparator circuit 49
Since the output side of is H, the AND circuit 21 provided as a gate for normal hand movement control in the hand movement control circuit 7 is in the ON state, and the frequency dividing circuit 6 is turned on.
Normal drive signal φ ₁ sent every minute from
is input to the forward rotation signal forming circuit 33 via the AND circuit 21 and the OR circuit 31, and as a result, the step motor 10 is driven one step at a time every minute (hereinafter referred to as the normal driving state). becomes.

(However, as a special condition, immediately after the watch returns to the current time display state from the alarm set time display state (described later), even if the watch 3 is in the normal position 3a, the contents of the current time counter 46 will be immediately updated. Although the contents of the pointer position counter 47 do not necessarily match, the operation in that case will be described later as an operation when switching the display, and the explanation will be omitted here.) In addition, in the normal driving state described above, The driving signal φ ₁ is supplied to the AND circuit 21 and the OR circuit 43,
44, the current time counter 46 and hand position counter 47 are also input, so the contents of both counters always remain consistent.
Each minute of the pointer 1 will be counted up as it advances.

On the other hand, as mentioned above, the reuse 3 is in the normal position 3a.
When the alarm function is controlled to be in the ON state with the button 4 also in the pulled out position 4b, the output side of the AND circuit 42 is H, so when the alarm set time arrives in this state (i.e. When the contents of the pointer position counter 47 match the contents of the alarm time counter 48 and a coincidence detection signal of H is output from the second comparator circuit 50), the alarm block 15
When the AND circuit 51 is turned on, the 2048Hz signal from the frequency divider circuit 6 is input to the buzzer drive circuit 52 via the AND circuit 51, and as a result, the buzzer 53 provided as an alarm element issues an alarm. Sound will be generated. If the alarm notification sound is not required, the alarm function may be turned off by setting the button 4 to the pressed position 4a and turning the switch _S3 off. In other words, in this state, the output side of the AND circuit 42 becomes L, so the AND circuit 51 is OFF.
Even if the comparison circuit 50 outputs an H match detection signal, the buzzer 53 will not be driven.

On the other hand, in the above-mentioned normal carrying state, the calendar drive mechanism 17 and the calendar drive control mechanism 19 are in the state shown in FIGS. 5 and 6, and receive the driving force from the wheel train 16 as described above.
The date plate 2 is being sent one tooth a day.

Furthermore, when the sleeve 3 is set at the normal position 3a as described above, even if the sleeve 3 is rotated and the switch lever 75 of the switch _S2 is brought into contact with the switch terminal d or e,
The output side of the AND circuits 37, 38, 39, 40 is
Both remain at L, therefore, AND circuits 26 and 27 provided as time correction signal control gates and AND circuits 28 and 29 provided as alarm time correction signal control gates,
Both remain in the OFF state. That is, in this state, the input function of the correction signal by the switch _S2 , which is linked to the rotation of the reuse 3, is prohibited from being executed.

Further, when the reuse 3 is set at the normal position 3a as described above, as shown in FIG.
is engaged with the vicinity of one end of the elongated hole 73b of the cannula 73. Here, since the width near the end of the elongated hole 73b is approximately the same as the diameter of the dowel 62c, the engagement between the elongated hole 73b and the dowel 62c causes the cannula 73 to be separated from the spring portion 73c. Even if it receives the spring force of , it does not rotate further in the direction of arrow C than the state shown in the figure, and therefore, the suspension wheel 61 is also held at the position shown in the figure. That is, in this state, the quick correction cam portion 61b of the suspension wheel 61 is located at a position slightly apart from the engagement pin 67b of the quick correction transmission lever 67 in the longitudinal direction of the operating shaft 60 as shown in the figure. Even if the reuse 3 is rotated and the screw wheel 61 is rotated, the cam portion 61b is not connected to the engagement pin 67b.
Therefore, the quick correction transmission lever 67 and the quick correction lever 68 are not operated, and no calendar correction operation is performed.

Although FIG. 10 shows a state in which the button 4 is set to the pulled-out position 4b, as long as the reuse 3 is set to the normal position 3a, the button 4 is not set to the pushed-in position 4a, for example. Even in this case, the switching lever 71 only moves in parallel in the direction of the arrow G along the two pins 72a and 72b, and the positions of the lever 73 and the wheel 61 are exactly the same as in the state shown in FIG. That is, even if the reuse 3 is rotated, the calendar is not corrected, as described above.

As described above, when the watch of this example is set to the normal position 3a (that is, when normally carried), regardless of the set position of the button 4, the rotating operation of the case 3 cannot be performed. , neither the hand 1 nor the date plate 2 is corrected.

Next, the operation of switching the display from the current time display state to the alarm set time display state will be explained. In addition, in this example clock, this display switching is as follows.
When the alarm function is in the ON state (i.e., button 4 is in the pulled out position 4b and switch S ₃ is
ON state).

As shown in FIG. 2, when the button 4 is in the pulled-out position 4b and the switch _S3 is in the ON state, when the reuse 3 is set to the 1st pull-out position 3b, the output side of the AND circuit 41 is Became H,
The output side of the NOR circuit 35 and inverter 36 is L
Then, the AND circuit 22 turns on. On the other hand, at the beginning of this state, the comparison circuit 5
The output side of 0 is L, and the INH circuit 24 provided as a display switching signal control gate is
Since it is in the ON state, the voltage from the frequency divider circuit 6 is
The display switching signal φ ₂ of 64Hz is input to the forward rotation signal forming circuit 33 via the INH circuit 24 and the OR circuit 31, and as a result, the step motor 10 rotates in the forward rotation direction at a frequency of 64Hz. The pointer 1 is driven in the forward rotation direction at high speed. The display switching signal φ ₂ output from the INH circuit 24 is also input to the pointer position counter 47 via the OR circuit 44, so that the pointer position counter 47 also counts in synchronization with the high-speed movement of the pointer 1. It will be uploaded. As a result, when the displayed time (hander position) of the hand 1 matches the alarm set time (that is, when the contents of the hand position counter 47 match the contents of the alarm time counter 48), the comparison circuit 50 Since the coincidence detection signal φ2 is output, the INH circuit 24 is turned off, and high-speed hand movement based on the display switching signal _φ2 is stopped. That is, when the comparison circuit 50 outputs a matching detection signal of H, it is determined that the display switching to the alarm set time has been completed, and the hand 1 is maintained in a state where the alarm set time is displayed.

At this time, the hand 1 is moved at high speed in the forward rotation direction by an amount corresponding to the relative difference between the content of the alarm time counter 48 and the content of the current time counter 46. For example, in the current time display state mentioned above, hand 1 is at 10 o'clock as shown in Figure 1.
30 minutes and current time counter 46
When the relative difference between the contents of the alarm time counter 48 and the contents of the alarm time counter 48 is 2 hours and 15 minutes in terms of hand movement (that is, [the contents of the alarm time counter 48] - [the contents of the current time counter 46] ]
= 135 = 2 x 60 + 15), then the step motor 10 is driven in the forward rotation direction at high speed by 135 steps, and as a result, the hand 1 moves at a high speed. The hand moves rapidly in the forward direction by an amount equivalent to 2 hours and 15 minutes, and stops when the alarm set time is 12:45 as shown in FIG.

Furthermore, in this alarm set time display state, turn the watch 3 in the right direction (direction of arrow R in Fig. 2).
Alternatively, by rotating it to the left (in the direction of arrow L in FIG. 2), it is possible to adjust the alarm set time to advance (addition) or delay (subtraction). That is, when the reuse 3 is rotated to the right or left and the correction input switch lever 75 is kept in contact with the switch input terminal d or e, the output side of the AND circuit 39 or 40 becomes H, and the AND circuit 28 Or 29 is ON
As a result, the correction signal φ ₃ with a frequency of about 32 Hz from the frequency divider circuit 6 is applied to the AND circuit 28 and the OR circuit 31 or the AND circuit 29 and
Forward rotation signal forming circuit 33 via OR circuit 32
Alternatively, since the signal is input to the reverse rotation signal forming circuit 34, the step motor 10 and the pointer 1 are correctively driven in the forward rotation direction or reverse rotation direction in response to the correction signal _φ3 . In this case, when reuse 3 is rotated clockwise, AND circuit 2
The correction signal φ ₃ outputted from the OR circuit 44
Since the information is also input to the pointer position counter 47 and the alarm time counter 48 via the pointer position counter 47 and the alarm time counter 45, when the pointer 1, that is, the alarm set time, is adjusted in the forward direction, the pointer position counter 47 and the alarm time counter 48 are inputted. Contents,
As a result, the relative difference between the contents of _the current time counter 46 and the contents of the alarm time counter 48 increases. It will change as you go. On the other hand, when the Reuse 3 is rotated to the left, the AND circuit 29
The correction signal φ ₃ output from the current time counter 46 is also input to the current time counter 46 via the OR circuit 43.
is counted up by the correction signal _φ3 , and as a result, the relative difference between the contents of the current time counter 46 and the contents of the alarm time counter 48 changes in a decreasing direction. To go.

As mentioned above, while the switch S ₃ is in the ON state and the reuse 3 is set to the 1st pull position 3b, the high-speed hand movement for display switching is in progress and the alarm set time is being corrected. Since the normal drive signal φ ₁ from the frequency dividing circuit 6 is input to the current time counter 46 via the AND circuit 22 and the OR circuit 43 even during execution, the current time counter 46 is This means that the count-up operation is continued according to the elapsed time.

By the way, in the watch of this example, as already explained based on FIG. 7 and FIG.
Since the regulation lever 66 is configured to disconnect the transmission of driving force from the wheel train 16 to the date plate 2, it is difficult to switch the display from the current time display state to the alarm set time display state. This prevents the date dial 2 from being advanced due to high-speed hand movement or hand movement for adjusting the alarm set time. In other words, reuse 3 is 1
When set to the stepped position 3b, even if the first date wheel 64 is rotated by the driving force from the wheel train 16 as the hands move, the feed claw portion 64c does not engage with the second date wheel 65. Because it is controlled by the alarm set time display state, date plate 2 is sent due to calling the alarm set time display state or correcting the alarm set time, and as a result, there is no possibility that the date display will be incorrect. There isn't.

Further, in the watch of this example, when the button 4 is set to the pulled-out position 4b and the rise 3 is set to the 1st pull-out position 3b as described above, as the rise 3 is rotated, The configuration is such that the correction of the date plate 2 is not performed.

In other words, FIG. 11 shows the above state,
In this state, the dowel 62c of the mandrel lever 62
As shown in the figure, is engaged with the wide part near the center of the elongated hole 73b of the cannula 73. On the other hand, the switching lever 71 is linked to the button 4,
When the protruding portion 71d is pulled upward in the drawing along the direction in which the fixing pins 62a and 62b are arranged (this is the same state as in FIG. 10), the protruding portion 71d is It is in a state of engagement with the portion 73d. Here, if there is no engagement between the protruding part 71b and the restricted part 73d, the diameter of the elongated hole 73b is larger than the diameter of the dowel 62c.
Because the width near the center of is wider, Kannuki 7
3 is the cannula shaft 7 due to the spring force of the spring 73c.
3a as the center of rotation in the direction of arrow C than in the illustrated state, but in reality, the cannula 73 is in the illustrated state due to the engagement between the protruding portion 71d and the regulated portion 73d. Further arrow C
It is regulated so that it cannot rotate in any direction. As a result, the cannula 73 is in the state shown in FIG. 11, and the suspension wheel 61 is also held in the position shown in the figure, but in this state, the quick correction cam portion 61b is Transmission lever 67
Because it is located away from the engagement pin 67b,
The rotation of the dial wheel 61 is not transmitted to the quick correction transmission lever 67, and therefore, the date plate 2 will not be corrected by rotating the reuse 3.

That is, the button 4 is set to the pulled out position 4b, and the reuse 3 is set to the 1st pulled position 3b.
In the state set to , only the hand 1 which is in the alarm set time display state is corrected by rotating the reuse 3, and the date plate 2
No corrections will be made.

Next, when the watch 3 is returned to the normal position 3a from the alarm set time display state, the hand 1 is moved at high speed in the reverse direction, returning to the current time display state. i.e. Reuse 3
When is returned to the normal position 3a, the output side of the AND circuit 41 returns to L, the output sides of the NOR circuit 35 and inverter 36 become H, and the AND circuit 22 becomes OFF. On the other hand, at the beginning of this state, the contents of the current time counter 46 and the contents of the pointer position counter 47 do not match each other, and the output side of the comparator circuit 49 is at L, so the AND circuit 2 is in the OFF state, and the INH circuit 23 and the INH circuit 25 provided as a display switching signal control gate are in the ON state. Therefore, in that state, the 64Hz display switching signal φ ₂ from the frequency dividing circuit 6
is, via the INH circuit 25 and OR circuit 32,
Since the signal is input to the reverse rotation signal forming circuit 34, the step motor 10 is immediately driven at high speed in the reverse direction, and the pointer 1 is moved at high speed in the reverse direction. Furthermore, the display switching signal φ ₂ outputted from the above-mentioned INH circuit 25 is connected to the OR circuits 43 and 45.
Since the current time counter 46 and the alarm time counter 48 are also input via the clock, the current time counter 46 and the alarm time counter 48 both count up in synchronization with the high-speed movement of the hands in the reverse direction. It turns out. In the above state, the normal drive signal _φ1 from the frequency dividing circuit 6 is connected to the INH circuit 23 and the OR
Since the current time counter 46 is inputted via the circuit 43, the current time counter 46 maintains a count-up operation according to the elapsed time. In addition, the above display switching signal _φ2
When the contents of the current time counter 46 match the contents of the pointer position counter 47 as a result of the count-up due to the input of
3 and 25 are turned OFF, the AND circuit 21 is turned ON, and high-speed hand movement based on the display switching signal φ ₂ is stopped. That is, comparison circuit 4
When a coincidence detection signal of H is output from 9, it is determined that the display switching to the current time display state has been completed, and the hand 1 has completely returned to the above-mentioned normal drive state again. In addition, at this time, guideline 1
This means that the hands have moved rapidly in the reverse direction by an amount corresponding to the relative difference between the contents of the alarm time counter 48 and the contents of the current time counter 46, and the alarm time counter 48 is This means that the value corresponding to is counted up.

By the way, when the high-speed hand movement in the reverse direction is performed to switch the display from the alarm set time display state to the current time display state, the watch 3 is first returned to the normal position 3a, and the calendar drive mechanism 17 is then returned to the normal position 3a. The calendar drive control mechanism 19 is also returned to its original normal carrying state.
Even if the date plate 2 becomes engaged with the second date wheel 65, the date plate 2 is sent in the reverse direction in order for the feed claw portion 64c to escape in the direction of disengaging from the second date wheel 65. This is the same as in the case of a general well-known pointer display type watch.

In other words, as is well known, in conventional pointer display watches with a calendar display, when the calendar display is quickly corrected using an external operating member, the calendar display member (date plate, etc.) becomes the driving side, and the calendar The feed wheel (date wheel, etc.) becomes the driven side, but in such a case, even if the calendar feed claw is already fully engaged with the calendar display member or the second calendar feed wheel, Even if the calendar display member is bent, the feed claw part will escape in the direction of disengaging based on the force received from the calendar display member so that the feed claw part will not be destroyed by the driving of the calendar display member. It is generally configured as follows. As a result, even if the calendar feed wheel is driven in the reverse direction when the pointer is corrected in the reverse direction, due to the intervention of the holding force of the calendar display member due to the spring control force of the movement control lever, the movement of the feed claw is Since the relative force relationship with the calendar display member is similar to that during the above-mentioned quick calendar correction, the feed pawl also operates to escape in the same way.

The above is the operation of a general well-known calendar-related mechanism, and the same applies to the case of the watch of this example, in which the first date wheel 64 is driven in the reverse direction J, as shown in FIG. In this case, the feed claw part 64c
engages with the second date wheel 65 from its rear side, but the force is determined by the geometrical relationship between the rear side of the feed claw portion 64c and the teeth of the second date wheel 65. Based on the operating state of the lever 69 and the elasticity of the elastic arm portion 64b, the feed claw portion 64c eventually moves toward the second day while bending the elastic arm portion 64b in the direction of the central axis 64a. turning wheel 65
direction (i.e., the direction in which the center axis 64a disengages)
The structure is such that it runs away in the direction of

In other words, in the timepiece of this example, as in the case of conventional pointer display type watches, a calendar feed wheel is used that is configured not to advance the calendar display member when rotating in the reverse direction. Even if the hands are moved at high speed in the reverse direction to switch from the alarm set time display state to the current time display state in a state where the transmission of driving force from the wheel train 16 to the date plate 2 is restored first, day board 2
The date will not be moved in the reverse direction, thus preventing the date display from being messed up as the hands move to change the display.

Next, we will briefly explain how to adjust the current time. The watch of this example is configured so that when the watch 3 is set to the second pull position 3c, the current time is adjusted, and in this state, the oscilloscope lever 62 is in contact with the terminal c,
The output side of the NOR circuit 35 becomes L and the AND circuit 2
1 becomes OFF, AND circuit 37,
38 is turned on. Further, the output side of the AND circuit 41 becomes L regardless of the state of the switch _S3 , and as a result, the AND circuit 22 becomes OFF and the output side of the inverter 36 becomes H. Here, unless this current time adjustment state is called immediately from the alarm set time display state, generally the contents of the current time counter 46 and the contents of the hand position counter 47 already match, and the comparison circuit 49 The coincidence detection signal is being output, that is, the display of hand 1 (pointer position) is indicating the current time, but when the current time adjustment state is called immediately from the alarm set time display state, etc. Like, comparison circuit 49
Since the INH circuit 25 is in the ON state when the output side of The hand 1 is moved at high speed in the reverse direction until the comparison circuit 49 outputs a coincidence detection signal of H (that is, until the current time display state is restored). In any case, with the comparison circuit 49 outputting an H match detection signal, rotate the lever 3 to the right or left to move the lever 75 to the terminal d.
Alternatively, if it is brought into contact with e, the output side of the AND circuit 37 or 38 becomes H and the AND circuit 26 or 27 is turned on, so the frequency dividing circuit 6
The correction signal φ ₃ from the AND circuit 26 and the OR
Circuit 31 or AND circuit 27 and OR circuit 3
2, it is input to the forward rotation signal forming circuit 33 or the reverse rotation signal forming circuit 34,
The step motor 10 is driven in the forward or reverse direction, and the pointer 1 is corrected in the forward or backward direction. Note that the correction signal φ ₃ outputted from the AND circuit 26 mentioned above is sent to the OR circuit 4.
3 and 44 to the current time counter 46 and pointer position counter 47, the counters 46 and 47 are kept in agreement with each other and counted up, and as a result, the amount of correction of the pointer 1 in the forward direction is inputted. The difference between the contents of the current time counter 46 and the contents of the alarm time counter 48 is decreased by a value corresponding to . Also, AND circuit 2
The correction signal φ ₃ outputted from 7 is sent to the OR circuit 43
is input to the alarm time counter 48 through the counter 48, and the counter 48 is counted up.As a result, the contents of the current time counter 46 and the alarm time counter 48 are updated by a value corresponding to the amount of correction of the pointer 1 in the reverse direction. Increase the difference between the content and the content.

Although not shown in the drawings, the states of each calendar-related mechanism when the reuse 3 is set to the two-step pull position 3c as described above are the same as when the reuse 3 is set to the normal position 3a. is almost the same. Therefore, in the current time adjustment state described above, driving force can be transmitted from the wheel train 16 to the date plate 2 as in the normal carrying state, so when the pointer 1 is corrected in the forward direction, ,
Depending on the time period in which the hands move, the date plate 2 is advanced by the calendar drive mechanism 17 described above.
Regarding the calendar quick correction mechanism 18, the adjustment wheel 61 is normally held in the same position as in the carrying state, and the quick correction cam 61b is located away from the engagement pin 67b of the quick correction transmission lever 67. , the date plate 2 is not corrected as a result of the rotation operation of the reuse 3.

Next, a description will be given of an operation for correcting the calendar display member in the timepiece of this example.

When the button 4 is set to the push-in position 4a and the watch 3 is set to the 1st pull position 3b, the watch of this example enters the calendar quick adjustment state, and when the watch 3 is rotated, the date plate is changed. It is configured in such a way that it can be modified. 1st
FIG. 2 is a diagram showing this calendar quick correction state.

That is, when the rear lever 3 is set to the first pull position 3b, the mandrel lever 62 is in the position shown in FIG.
It is in a state where it is engaged with the wide part near the center of the elongated hole 73b. (The above is the same as in the case of Fig. 11.) On the other hand, the button 4 is in the pressed position 4a.
Since the switching lever 71 is set to
is pushed down in the drawing along the direction in which the two fixing pins 72a and 72b are lined up (moved in the direction of arrow G compared to the case in FIG. 10), and protrudes. The portion 71d is also lower in the drawing than in the case of FIG. 11. Therefore, in this state, unlike the case of FIG. There is no such thing as deterring
Moreover, as mentioned above, since the width of the central part of the elongated hole 73b is larger than the diameter of the dowel 62c, the cannula 73 is longer due to the spring force of the spring portion 73c compared to the state shown in FIG. Hole 73b
It rotates about the shaft 73a in the direction of arrow C until the lower wall in the drawing abuts against the dowel 62c, and then it reaches a stable state (that is, the state shown in FIG. 12). As a result, the Tsuzumi wheel 61 that is engaged with the head of Kannuki 73 also
Compared to the case in FIG. 11, the quick correction cam 61b is held at a position moved upward in the drawing (that is, in the direction of arrow C), and in the longitudinal direction of the operating shaft 60, the quick correction transmission lever 67
This is the same position as the engaging pin 67b. Therefore,
In this state, the right direction (R direction) of Reuse 3
When the adjustment wheel 61 is rotated to the right by the rotation operation, the cam portion 61b engages with the engagement pin 67b, so the quick correction transmission lever 67 rotates in the direction of arrow M about the shaft 67a. As a result, the quick correction lever 68 is rotated in the direction of arrow N about the shaft 68a. As a result, the quick correction claw 68c of the quick correction lever 68 engages with the teeth of the date plate 2, and the date plate 2
This means that one tooth is advanced for each degree of rotational movement. Note that when the reuse 3 is rotated in the left direction (arrow L direction) contrary to the above, the quick correction transmission lever 67 and the quick correction lever 68 are also rotated in the opposite direction to the above. Naru, day board 2
It is clear that no correction drive is performed.

On the other hand, as mentioned above, button 4 is pressed to position 4.
When set to a, Switch S ₃
Since it is in the OFF state, in this state,
Even if the reuse 3 is set to the first pull position 3b and the oscilloscope lever 62 is in contact with the terminal b, the output side of the AND circuit 41 remains at L. Therefore, in the above-mentioned calendar quick correction state, the output side state of each gate constituting the switch input control circuit 13 shown in FIG. 4 and the ON-OFF state of each gate constituting the hand movement control circuit 7 are are all the above reuse 3
This is the same as in the normal carrying state when the camera is set at the normal position 3a. In other words, when the button 4 is set to the push-in position 4a, even if the reuse 3 is set to the 1st pull position 3b and the calendar is in the quick correction state, the display on the hand 1 will be in the alarm set time display state. Step motor 1 without being switched
0 and pointer 1 maintain the normal driving state in the current time display state. In this state, even if the switch lever 75 is brought into contact with the terminal d or e by rotating the reuse 3, the output sides of the AND circuits 37, 38, 39, and 40 become H, and the AND circuits 26, 27 ,28,
29 is never in the ON state, it is clear that neither the current time nor the alarm set time is corrected.

In other words, in the above-described early calendar correction state, only the date plate 2 is controlled to be corrected by rotating the reuse 3.

As described above, according to the present invention, even in a watch configured to switch the same pointer between the current time display state and the display state related to additional functions, as in the case of the conventional pointer display type timepiece, It becomes possible to provide a very easy-to-read calendar display function using a date board or the like as a display member.

That is, according to the present invention, it is possible to prevent the calendar display member from being moved due to high-speed hand movement for changing the display of the hands, and as a result, the calendar display is prevented from going out of order. Pointer display type electronic watches also have additional functions such as alarms that share the hands as a display member, and a date board that is configured to be sent by the driving force from the wheel train as display members. It becomes possible to have both the calendar display function and the calendar display function without contradicting each other.

In addition, in the above-mentioned embodiment, in the normal portable state,
The first date wheel 64 equipped with a calendar feed claw portion 64c is connected to a second date wheel 6 that is provided separately.
5, the date plate 2, which is a calendar display member, is sent through the first date wheel 64.
It is clear that the present invention is also applicable to a calendar drive mechanism configured to feed the date plate 2 more directly. That is, the existence of the second date wheel 65 in the above-mentioned embodiment is provided to adjust the forward rotation direction of the date dial 2 in correlation with the type of the calendar quick correction mechanism 18, etc. Even in the case of the embodiment, if the forward rotation direction of the date plate 2 is set in the opposite direction, the installation of the second date wheel 65 becomes unnecessary.

Furthermore, in the above-mentioned embodiment, the alarm function is configured as a 24-hour system (a type in which the alarm set time reaches once a day in a 24-hour cycle); It is clear that a 12-hour alarm function (a type in which the alarm set time arrives at a 12-hour cycle without distinguishing between morning and afternoon) may also be used. Note that in order to set the alarm function to 12 hours, the step motor 10 must be set to 1 in the normal driving state, as in the case of the above-mentioned embodiment.
Assuming that the motor is driven one step at a time every minute, the number of motor drive pulses required for the pointer 1 to make one revolution in 12 hours is 60 x 12 = 720.
Each counter 46, 4 of the above-mentioned counting processing circuit 14
7 and 48 can be configured as a 720-decimal up counter.

Further, as in the case of the above-mentioned embodiment, when configuring a 24-hour alarm function, it is also possible to add AM and PM display sections configured to synchronize with the position of the hand 1.
