Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a pointer display type electronic watch with an alarm device.

[Conventional technology]

In recent years, there has been a demand for additional functions such as alarm devices and chronograph devices for pointer display type electronic watches.
-87083, the relative difference between the hand display position and the current time (hereinafter, the current time is simply referred to as time) and between the hand display position and the alarm set time. A pointer display type with an alarm device configured so that the pointer can be selectively switched between a time display state and an alarm set time display state by providing means for counting or detecting coincidence. Electronic clocks have already been realized.

[Problem that the invention attempts to solve]

However, in the conventional electronic watch with a pointer display equipped with an alarm device as described above, it is not possible to check the alarm set time without performing an operation to switch the display, and it is also difficult to actually switch the display using the pointer. Since the switching is performed by high-speed motor drive, it takes a long time to complete the switching, making it cumbersome to use.Furthermore, it is not possible to display both the time and the alarm set time at the same time. However, it has the disadvantage that it is prone to erroneous operation, especially when adjusting the time or alarm set time.

An object of the present invention is to provide a pointer display type electronic timepiece with an alarm device that can display the alarm set time even in normal times, and in which the adjustment operation of the alarm set time is easy to understand.

[Means for solving the problem] In order to achieve the above object, the present invention includes a main pointer for displaying the time and a first pointer for driving the main pointer.
a motor, a sub-pointer for selectively displaying the time and alarm set time, and a second pointer for driving the sub-pointer.
the motor, the reuse configured to be settable to the normal position, the outermost pulled-out position, and the intermediate pulled-out position, and the function of counting the relative relationship between the display position of the sub-pointer, the time, and the alarm set time. a display position of the sub pointer in the counting processing means, at least when the reuse is set at the normal position and when it is moved from the normal position and set at the intermediate drawer position; By controlling the relative relationship between the alarm time and the alarm time to match, the sub pointer is controlled to display the alarm set time, and at least the intermediate drawer is moved from the outermost drawer position by the second pointer. In the state where the display position of the sub-pointer in the counting processing means is set to the time, the sub-pointer is controlled to a state where the relative relationship between the display position of the sub-pointer in the counting processing means and the time shows coincidence, thereby controlling the sub-pointer to a time display state. The display switching control means and the display switching control means supply a correction drive signal to the second motor in response to a rotational operation of the reuse in a state where the reuse is set at the intermediate draw-out position by movement from the normal position. a sub-pointer display alarm time adjusting means for correcting the display position of the sub-pointer and correcting the relative relationship between the display position of the sub-pointer in the counting processing means and the time; a main pointer display time adjusting means for correcting the display of the main pointer in response to a rotational operation of the reuse; In the set state, the display position of the sub pointer is corrected by supplying a correction drive signal to the second motor in response to the rotational operation of the reuse, and the display position of the sub pointer in the counting processing means is corrected. a sub-pointer display time adjusting means for correcting the relative relationship between the display position of the auxiliary pointer and the alarm set time, and the display position of the sub-hander being coincident with the time when the reuse is set at the normal position. The present invention is characterized in that it is provided with a detection means for detecting the detection means, and an alarm means configured to generate an alarm sound based on the detection result of the detection means.

[Effect]

In the electronic watch with an alarm and pointer display according to the present invention, when the watch is normally carried with the watch in its normal position, the sub-hand displays the alarm set time, and from this state the watch must be moved to the intermediate pull-out position and rotated. For example, the alarm set time is corrected as is. Furthermore, at least when the reuse is moved from the outermost pulled out position and set to the intermediate pulled out position, the secondary hand is switched to the time display state, but in that state there is a discrepancy between the display by the secondary hand and the main hand. If approved, it is possible to adjust the time displayed by the secondary hand to the time displayed by the main hand by simply rotating the reuse.

〔Example〕

Embodiments of the present invention will be described below with reference to the drawings.

1 to 3 show a pointer display type electronic watch with an alarm device according to one embodiment of the present invention,
The figure and FIG. 2 are plan views showing the external appearance.

The timepiece of this embodiment has a main pointer 1 consisting of an hour hand, a minute hand, and a second hand as display members, and a sub-pointer 2 consisting of an hour hand and a minute hand, and external operation members include a normal position 3a, an intermediate position 3b, and a maximum position. It includes a lid 3 configured to be settable to three axial positions including an external pull-out position 3c, and a push-pull button 4 configured to be set to a pushed-in position 4a and a pulled-out position 4b.

In the watch of this embodiment, as shown in FIG. 1, the first case 3 is set at the normal position 3a, and as a result of movement from the normal position 3a, it is set at the intermediate drawer position 3b. In this state, the sub pointer 2 is controlled to display the alarm set time, but in a special state, as shown in FIG. 2, the intermediate drawer 3 is moved from the outermost drawer position 3c. When set to position 3b, the sub-hand 2 is controlled to display the time. In the alarm device of this embodiment, it is necessary to assume that the display position of the sub-hand 2 in the time display state is aligned with the time displayed by the main hand 1, and this premise is not adhered to. If so, the correlation between the time displayed by the main hand 1 and the alarm set time displayed by the sub hand 2 will also be maintained correctly.

Next, FIG. 3 is a circuit diagram of the timepiece of this embodiment.

The output signal from the crystal oscillation circuit 5 is transmitted to a frequency dividing circuit 6.
After the frequency is divided to 1Hz by
The signal is input to the main pointer drive signal forming circuit 8 and the sub frequency dividing circuit 11 via the INH circuit 7. In addition, the main pointer motor drive circuit 9 normally responds to signals sent from the main pointer drive signal forming circuit 8.
The main pointer step motor 10 is driven every second. The sub frequency dividing circuit 11 further divides the frequency of the 1 Hz signal to a 1/60 Hz signal _Φ4 .

On the other hand, among the switches constituting the switch block 12, the switch _S1 is linked to the axial position of the sleeve 3, so that the sleeve 3 is in the normal position 3a.
When set to , terminal a becomes ON, and when set to outermost drawer position 3c, terminal c is closed and turns ON. However, when set to middle drawer position 3b, terminal a becomes ON. , terminals a and c are controlled to be in a neutral state where both terminals are OFF.

The switch _S2 is linked to the rotational operation of the reuse 3, and is configured such that when the reuse 3 is rotated to the right, the d terminal is turned on, and when the reuse 3 is rotated to the left, the e terminal is turned on.

The switch _S3 is linked to the axial position of the button 4, and is configured to be in the OFF state when the button 4 is set in the pushed-in position 4a, and to be in the ON state when it is set in the pulled-out position 4b.

In addition, the switch S ₃ has an alarm function ON ~
This is provided to control the OFF state.
When the button 4 is set to the pulled-out position 4b, the alarm function is controlled to be in the OFF state.

Switch input control circuit 13 and hand movement control circuit 14
is provided mainly as display switching control means and correction input control means for the sub-pointer 2, and the switch input control input circuit 13 controls the hand movement control circuit 14 in accordance with the input from the switch block 12 described above. form an output signal for
Further, the hand operation control circuit 14 transmits a signal of any frequency from the frequency dividing circuit 6 or the sub-frequency dividing circuit 11 to the sub-pointer, which will be described later, in accordance with a signal from the switch input control circuit 13 or a counting processing circuit 18, which will be described later. By controlling which part of the drive signal forming circuit 15 or the counting processing circuit 18 is supplied, as a result, when switching the display of the sub-pointer 2, the operation state at the time of correction (i.e., the step motor for the sub-pointer) is controlled. 17 drive states).

On the other hand, the sub pointer drive signal forming circuit 15 includes a forward rotation signal forming circuit 20 and a reverse rotation signal forming circuit 21.
Depending on whether the forward rotation signal forming circuit 20 outputs the forward rotation signal to the sub-pointer motor drive circuit 16 or the reverse rotation signal forming circuit 21 outputs the reverse rotation signal, The sub-pointer step motor 17 is configured to be selectively driven in either the forward direction or the reverse direction.

Further, the counting processing circuit 18 includes a hand movement control circuit 14.
By performing processing such as counting of the signals supplied from the counter, it is possible to determine whether the switching of the display by the sub-pointer 2 has been completed or when the alarm set time has arrived. An alarm block 19 including a buzzer 27 is provided on the output side.
is connected. The counting processing circuit 18 includes a first counter 22 for counting and holding the relative difference between the time and the sub-hand display position, and a first counter 22 for counting and holding the relative difference between the sub-hand display position and the alarm set time. A second counter 23 for holding the display, and the first and second counters 2 for determining the completion of display switching of the sub-pointer 2 and the arrival of the alarm set time.
It has first and second zero detection circuits 24, 25, etc., which detect that the contents of 2 and 23 have become zero, respectively. That is, the first and second zero detection circuits 2
4 and 25, the display position of the secondary hand is the time,
It has the function of detecting coincidence with the alarm set time, and is configured so that the output side becomes H only when coincidence is detected.

In the timepiece of this embodiment, one step of driving the sub-pointer motor 17 is configured to correspond to the movement of the sub-pointer 2 in one minute. In order to drive the sub pointer motor 17 with 60×12=720 pulses, the first and second counters 2 are
Both 2 and 23 are configured as up/down counters in 720 decimal.

Next, the operation of the timepiece of this embodiment will be explained.

However, the circuit in Figure 3 operates with positive logic, so when it is simply written as H or L,
It is assumed that each of these signals is logically at an H level or an L level.

First, as shown in Fig. 1, when the reuse 3 is set to the normal position 3a (switch S ₁ is in the ON state with respect to the a terminal) and is in the normal carrying state, the sub pointer 2 is activated by the alarm. The display state is maintained at the set time. Here, the fact that the sub-pointer 2 is displaying the alarm set time means that the content of the second counter 23 is zero, that is, the output of the second zero detection circuit 25 is H. This means that in this state, the output side of the OR circuit 36 is H and the AND circuit 46 is in the ON state.
The 1/60Hz signal Φ ₄ from the sub frequency divider circuit 11 is
The signal is input to the down counter input terminal 22d of the first counter 22 via the AND circuit 46 and the OR circuit 54. Therefore, in this state, the sub frequency divider circuit 1
Every time the signal Φ ₄ is supplied with a period of 1 minute from 1,
The first counter 22 will be decremented by one. (However, as a special condition, as described later, immediately after the sub-hand 2 starts returning from the time display state to the alarm set time display state, the second hand immediately changes to the second one even though the crown 3 is in the normal position 3a. Although the content of the counter 23 does not become zero and the second output of the zero detection circuit 25 becomes H, the operation in that case will be described later as an operation when switching the display of the sub-pointer 2, and will not be described here. (Description will be omitted.) On the other hand, when the reuse is in the normal position 3a and the button 4 is in the pressed position 4a as described above, the output side of the INH circuit 39 is at H level.
Therefore, when the alarm set time arrives in this state (that is, when the content of the first counter 22 becomes zero and the output side of the first zero detection circuit 24 becomes H),
The AND circuit 57 is turned on, and the 2048Hz signal from the frequency dividing circuit 6 is input to the buzzer drive circuit 26 via the AND circuit 57, and as a result, an alarm sound is generated from the buzzer 27 provided as an alarm element. will be done.

That is, in this embodiment, the reuse 3 is in the normal position 3a, and the button 4 is in the pressed position 4.
a, the first zero detection circuit 24 detects that the content of the first counter 22 has become zero (that the display position of the sub-pointer 2 matches the time), and the alarm is set. Detects that the time has arrived, and sounds the buzzer 2 based on the detection result.
7 to generate an alarm sound.

In addition, when the above-mentioned reuse is in the normal position 3a and the sub pointer 2 is displaying the alarm set time, a flip-flop circuit (hereinafter abbreviated as FF) is activated.
30 is in a reset state, but when the reuse 3 is moved from this state to the intermediate draw-out position 3b, the output side of the NOR circuit 31 becomes H, and the AND
Since the output side of the circuit 33 also becomes H, the output side of the AND circuit 37 also becomes H. Therefore, if you rotate Reuse 3 to the right (or left) in this state,
Switch _S2 is turned on to terminal d (or e), and the correction signal _Φ2 from frequency divider circuit 6 is
The normal rotation signal forming circuit 20 (or AND circuit 49, OR circuit 5
2 to the reversal signal forming circuit 21), the sub pointer motor 17 and the sub pointer 2
rotates forward (or reverse) according to correction signal Φ ₂
It will be corrected and driven in the direction.

In this case, the correction signal Φ ₂ outputted via the AND circuit 48 (or 49) when the reuse 3 is rotated in the right (or left) direction is output from the OR circuit 53.
(or 54), it is also input to the up-count input terminal 22a (or down-count input terminal 22d) of the first counter 22.
When the sub-pointer 2, that is, the alarm set time, is adjusted in the forward (or backward) direction, the contents of the first counter 22 are also adjusted up (or down) in accordance with the correction signal _Φ2 .

Furthermore, when the Reuse 3 is set to the outermost pulled-out position 3c and rotated, the time displayed by the main hand 1 is corrected, as in the case of well-known hand display type electronic watches (in that case). The correction method may be either by mechanical rotation transmission from the reuse 3 to the main pointer 1 or by high-speed drive of the main pointer motor 10.)
In this embodiment, when the reuse 3 is set to the outermost pulled-out position 3c (when the switch _S1 is turned on to the terminal c), the sub-hander 2 is configured to be switched to the time display state. ing.

First, when the reuse 3 is set to the outermost drawer position 3c, the INH circuit 7 is turned off, so
Sub frequency divider circuit 1 of 1Hz signal Φ ₃ from frequency divider circuit 6
1 is stopped, and the driving of the main hand 1 with a 1 second cycle is stopped. At the same time, the FF 30 is inverted to the set state, and the output side of the OR circuit 34 becomes H. Furthermore, in this initial state, the content of the first counter 22 has not yet reached zero, so the output side of the first zero detection circuit 24 is at L.
The INH circuit 41 is turned on. Therefore, in this state, the 64Hz display switching signal Φ ₁ from the frequency dividing circuit 6 is input to the reversal signal forming circuit 21 via the IND circuit 41 and the OR circuit 52, and as a result, the auxiliary pointer motor 17 And the sub pointer 2 is driven at high speed in the reverse direction. In addition, the display switching signal Φ ₁ outputted via the INH circuit 41 is OR
Since it is also input to the down-count input terminal 22d of the first counter 22 and the up-count input terminal 23u of the second counter 23 via circuits 54 and 55, it is synchronized with the high-speed movement of the sub-pointer 2 in the reverse direction. Thus, the first counter 22 and the second counter 23 count down and count up, respectively.

As a result of the above, when the display on the sub-pointer 2 reaches the time (that is, when the content of the first counter 22 becomes zero and the output of the first zero detection circuit 24 becomes H), the INH circuit 41 goes into the OFF state. Therefore, high-speed driving of the sub-pointer motor 17 and the sub-pointer 2 in the reverse direction is also stopped. That is, when the content of the first counter 22 becomes zero and the output of the first zero detection circuit 24 becomes H, it is determined that the switching of the sub-hand 2 to the time display state is completed.

Furthermore, when the output of the first zero detection circuit 24 becomes H and the switching of the sub hand 2 to the time display state is completed, the output side of the AND circuit 35 becomes H,
Frequency divider circuit 6 will be held in a reset state.

Next, when the reuse 3 is moved from the outermost drawer position 3c to the intermediate drawer position 3b as shown in FIG.
The output side of the circuit 31 becomes H, and the output side of the AND circuit 32 becomes H, but as a result, the output side of the OR circuit 34 also maintains H, so the sub hand 2 maintains the time display state. . As a special case, after the Louise 3 is set to the outermost pulled-out position 3c, but before the sub-hand 2 has completely switched to the time display state, when the Louise 3 is further moved to the intermediate pulled-out position 3b. First, the display switching operation of the sub-pointer 2 is continued, but this switching operation is similar to the operation when the reuse 3 is set to the outermost drawn-out position 3c described above. (However, in that case, since the INH circuit 42 is in the ON state, when the signal Φ ₄ is output from the sub frequency divider circuit 11, the signal is passed through the INH circuit 42 and the OR circuit 54 to the first counter 2
2, the first counter 22 is input to the down-count input terminal 22d of the sub-frequency divider circuit 1.
It also counts down in response to the signal from 1. ) In any case, when the reuse 3 is moved from the outermost drawer position 3c and set to the intermediate drawer position 3b, since the output side of the AND circuit 32 is H as described above, the first zero detection circuit 24 When the output of the AND circuit 38 becomes H and the switching of the sub hand 2 to the time display state is completed, the output side of the AND circuit 38 is also controlled to be H. Therefore, when the reuse 3 is rotated in the right (or left) direction in this state, the switch S ₂ is turned on to the terminal d (or e), and the correction signal Φ ₂ from the frequency dividing circuit 6 becomes AND. Forward rotation signal forming circuit 20 (or AND circuit 45, OR circuit 44 and OR circuit 51)
In order to input the signal to the reverse rotation signal forming circuit 21) via the circuit 52, the sub pointer motor 17 and the sub pointer 2 are correctively driven in the forward (or reverse) direction according to the correction signal _Φ2 . It turns out.

In this case, the correction signal Φ ₂ outputted via the AND circuit 44 (or 45) when the reuse 3 is rotated in the right (or left) direction is output from the OR circuit 56.
(or 55), it is also input to the down-counting input terminal 23d (or up-counting input terminal 23a) of the second counter 23.
When the time displayed by the sub-pointer 2 is adjusted in the forward (or backward) direction, the contents of the second counter 23 are also adjusted down (or up) in accordance with the correction signal Φ ₂ . It will be done.

In other words, when the time displayed by the main hand 1 is corrected by setting the reuse 3 to the outermost pull-out position 3c, a discrepancy occurs between the display position of the sub-hand 2 in the time display state and the time displayed by the main hand 1. In such a case, the time displayed by the sub-hand 2 can be aligned with the time displayed by the main hand 1 by moving the reuse 3 from the outermost draw-out position 3c to the middle draw-out position 3b and rotating it.

It should be noted that when the Louise 3 is moved from the outermost pulled-out position 3c and set to the intermediate pulled-out position 3b as described above, the main hand 1 continues to move every second as in normal times. In other words, when the reuse 3 is moved from the outermost drawer position 3c and set to the intermediate drawer position 3b, there is no effect on the drive of the main hand 1, so the display time of the sub-hander 2 is corrected. Main guideline 1
This prevents the display from going awry.

In addition, when the output of the first zero detection circuit 24 becomes H and the switching of the sub hand 2 to the time display state is completed, the output side of the AND circuit 38 becomes H and the AND circuit 43 becomes ON state. In order to
The 1-minute cycle signal Φ ₄ from the sub frequency divider circuit 11 is ANDed
The signal is input to the forward rotation signal forming circuit 20 via the circuit 43 and the OR circuit 51, and as a result, the sub-pointer 2 is also moved in accordance with the passage of time. In that case, the signal Φ ₄ output from the AND circuit 43 is
Since the input is also input to the down-counting input terminal 23d of the second counter 23 via the OR circuit 56, the second counter 23 maintains the down-counting operation according to the driving of the sub-pointer 2 in one-minute cycle. Become.

Next, the operation when the first reuse 3 is returned to the normal position 3a will be described.

First, since the switch _S1 is turned on with respect to the a terminal, the output side of the OR circuit 36 becomes H. In the initial state in this case, the content of the second counter 23 is generally not zero, so the output side of the second zero detection circuit 25 is L, and the INH circuit 47
is in the ON state. Therefore, in this state, the 64Hz display switching signal _Φ1 from the frequency divider circuit 6 is
The signal is input to the forward rotation signal forming circuit 20 via the INH circuit 47 and the OR circuit 51, and as a result, the sub pointer motor 17 and the sub pointer 2 are driven at high speed in the forward direction. Further, the display switching signal Φ ₁ outputted via the INH circuit 47 is transmitted to the up-counting input terminal 22u of the first counter 22 and the down-counting input terminal 23d of the second counter 23 via the OR circuits 53 and 56. Since the input is also input to the first counter 22 and the second counter 23 in synchronization with the high-speed movement of the sub-pointer 2 in the normal rotation direction,
will count up and count down, respectively.

Note that the AND circuit 46 is in the ON state even during this high-speed hand movement, so when the sub-divider circuit 11 outputs the signal Φ ₄ of one division period, the signal is sent to the AND circuit 46 and the OR circuit. 54 to the down-counting input terminal 22d of the first counter 22, in this state the first counter 22 will also down-count in response to the signal from the sub frequency divider circuit 11.

As a result of the above, when the display on the sub-pointer 2 coincides with the alarm set time (that is, when the content of the second counter 23 becomes zero and the output of the second zero detection circuit 25 becomes H), the INH circuit 47 The state is turned OFF, and high-speed driving of the sub-pointer motor 17 and the sub-pointer 2 in the normal rotation direction is also stopped. That is, when the content of the second counter 23 becomes zero and the output of the second zero detection circuit 25 becomes H, it is determined that the switching of the sub-hand 2 to the alarm set time display state is completed.

[Effect of idea]

As mentioned above, in the clock of this invention,
As long as the reuse is carried in its normal position, the secondary pointer will continue to display the alarm set time. The alarm set time can be confirmed without any intervention, and the alarm set time can be adjusted by simply moving the reuse from the normal position to the intermediate drawer position and rotating it, making the operation very easy. It will be simple and easy to understand. Furthermore, if you pull out the reuse to the outermost position and use the main hand to correct the displayed time, the time displayed by the main hand and the time displayed by the secondary hand will no longer match, and as a result In this case, the relationship between the time displayed by the main hand and the alarm set time shown by the sub-hand will also be disrupted, but according to the present invention, after the time displayed by the main hand is corrected, If you simply set the Reuse to the intermediate drawer position and rotate it, you can easily match the time displayed by the secondary hand with the time displayed by the main hand, and the time displayed by the main hand and the time displayed by the secondary hand can be easily adjusted. It is possible to restore the relationship with the alarm set time to a proper one. In other words, according to the present invention, the relationship between the time displayed by the main hand, the time displayed by the sub-hand, and the alarm set time can be easily checked and corrected by operating a single reuse. becomes possible.

In the above-mentioned embodiment, when the reuse 3 is set to the outermost drawer position 3c, the sub pointer 2
is configured to be controlled to the time display state, but the sub hand 2 is controlled to the time display state only when the reuse 3 is moved from the outermost drawer position 3c and set to the intermediate drawer position 3b. It is also possible to configure
