Abstract

PURPOSE:To make special operation unnecessary in the confirmation of alarm setting time and to simplify correction operation, by keeping the display state of alarm setting time by an auxiliary hand so far as a timepiece is carried in such a state that a first crown is present at a usual position. CONSTITUTION:At a usual carrying time when a firs crown 3 is present at a usual position 3a, an auxiliary hand 2 displays alarm setting time and, if a second crown 4 is set to a predetermined draw-out position in this state to perform rotary operation, the alarm setting time is corrected as it is. When at least both crowns 3, 4 are set to predetermined draw-out positions 3b, 4b, the auxiliary hand 2 is changed over to a time display state but, when shift is confirmed between the display by the auxiliary hand 2 and the display by a main hand 1 in this state, if the second crown 4 is subjected to rotary operation, the time displayed by the auxiliary hand can be matched with the time displayed by the main hand 1.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a pointer display type electronic timepiece 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. Counts the relative difference between the 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, or detects a match. A pointer display type electronic watch with an alarm device has already been realized in which the pointer can be selectively switched between a time display state and an alarm set time display state by providing a means or the like.

[Problem that the invention seeks 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 not possible to actually switch the display using the pointer. Because this is done by high-speed motor drive, it takes time to complete the switching, making it cumbersome to use.Furthermore, it is not possible to display both the time and alarm cent time at the same time. This method has drawbacks such as being prone to erroneous operations, especially when adjusting the time or alarm set time.

SUMMARY OF THE INVENTION An object of the present invention is to provide a pointer display type electronic timepiece with an alarm device that can display an alarm cent time even during normal use, and in which the operation for adjusting the alarm set time is easy to understand.

[Means for solving problems]

In order to achieve the above object, the present invention includes a main pointer that displays the time, a first motor that drives the main pointer, and a main pointer that is set at a predetermined pullout position and rotated to display the display by the main pointer. a first crown configured to correct the time; a sub-pointer that selectively displays the time and alarm set time; a second motor that drives the sub-pointer; a second crown configured to correct the display by the sub-pointer by controlling the sub-pointer to a display state of the alarm set time when the first crown is set to the normal position; and a sub-pointer display control means configured to control the sub-pointer to a time display state when both the first and second crowns are set at the predetermined pulled out position; a detection means configured to detect that the display position coincides with the time, and at least when the first and second crowns are both set to the normal position, based on the detection result of the detection means; The present invention is characterized in that an alarm means configured to generate an alarm sound is provided.

[Effect]

In the electronic watch with alarm and pointer display according to the present invention, when the first crown is in the normal position and the watch is normally carried,
The secondary pointer displays the alarm cent time, and in this state the second
Simply set the crown to the predetermined pulled out position and rotate it to adjust the alarm set time. Furthermore, when both the first and second crowns are set to the predetermined pulled out position, the sub hands are also switched to the time display state, but in this state there is a discrepancy between the display by the sub hands and the main hand. If approved, by rotating the second crown, it is possible to set the time displayed by the secondary hand to the time displayed by the main hand.

〔Example〕

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

1 to 3 show a pointer display type electronic timepiece with an alarm device according to an embodiment of the present invention, and FIGS. 1 and 2 are plan views showing the external appearance thereof.

The timepiece of this embodiment has a main hand 1 consisting of an hour hand, a minute hand, and a second hand as a display member, and a sub-hander 2 consisting of an hour hand and a minute hand, and has a first crown 3 and a second crown 3 as external operating members. It is equipped with 4 crowns.

The first and second glue uses 3.4 are respectively in the normal position 3a.
, 4a, and can also be set at pull-out positions 3b, 4b. Note that in the watch of this example, the first
As shown in the figure, when the first crown 3 is set to the normal position 3a, the secondary pointer 2 is controlled to display the alarm set time, but as shown in FIG. 2 as a special state. When the first gauge 3 is set at the pull-out 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 must be adhered to. For example, the correlation between the time displayed by the main hand 1 and the alarm set time displayed by the sub hand 2 is also 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 passed through the frequency dividing circuit 6 to IH
After the frequency is divided to z, the inhibitor (hereinafter referred to as I N H
The signal is inputted to the main pointer drive signal forming circuit 8 and the frequency dividing circuit 11 via the circuit 7. The main pointer motor drive circuit 9 normally drives the main pointer step motor 10 every second in response to a signal sent from the main pointer drive signal forming circuit 8. The frequency dividing circuit 11 further divides the frequency of the I Hz signal to a signal Φ4 of 1/60 Hz.

On the other hand, among the switches constituting the switch block 12, the switch S1 is linked to the axial position of the first crown 3, and when the crown 3 is set to the normal position 3a, it is in the OFF state, and when the crown 3 is set to the normal position 3a, it is in the OFF state. It is configured to be in an ON state when set. The switch S is linked to the axial position of the second crown 4, and the crown 4 is set to the normal value W4? It is configured to be in an OFF state when set to , and to be in an ON state when set to the pull-out position 4b. The switch S is linked to the rotation of the second crown, so that when the second crown 4 is rotated to the right, the a terminal is turned on, and when the second crown is rotated to the left, the b terminal is turned on. It is configured.

The switch input control circuit 13 and the hand movement control circuit 14 are mainly provided as display control means for the sub-pointer 2, and the switch input control circuit 13 controls the hand movement control circuit 14 according to the input from the switch block 12 described above. Form an output signal for control.

Further, the hand operation control circuit 14 converts any frequency signal from the frequency dividing circuit 6 or the dividing frequency dividing circuit 11 into a breakage needle drive signal (described later) according to signals from the switch input control circuit 13 and the counting processing circuit 18 (described later). By controlling which part of the forming circuit 15 and counting processing circuit 18 is supplied, the operation state of the sub-pointer 2 when switching or correcting the display (i.e., the step motor 17 for the sub-pointer) is controlled. It functions to control the driving state B).

On the other hand, the breakage needle drive signal forming circuit 15 has 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 a forward rotation signal to the sub-pointer motor drive circuit 16 or the reverse rotation signal forming circuit 21 outputs a reverse rotation signal,
The sub-pointer step motor 17 is configured to be selectively driven in either the forward direction or the reverse direction.

Furthermore, the counting processing circuit 1 performs processing such as counting signals supplied from the hand movement control circuit 14, so that it can judge whether the display switching by the sub-hand 2 has been completed or the alarm set time has arrived. An alarm block 19 including a buzzer 27 is connected to the output side of the counting processing circuit 18. The counting processing circuit 18 is
A first counter 22 for counting and holding the relative difference between the time and the sub-phase hand display position, and a first counter 22 for counting and holding the relative difference between the sub-phase hand display position and the alarm cent time. In order to determine the completion of display switching of the counter 23 and the sub-pointer 2 and the arrival of the alarm cent time, the first
It has first and second zero detection circuits 24 and 25 that detect when the contents of the first and second counters 22 and 23 respectively become zero. That is, the first and second zero detection circuits 24
．． 25 has the function of detecting that the display position of the sub-hand 2 coincides with the time and the alarm set time, respectively, and is configured so that the output side becomes H only when a coincidence is detected.

The timepiece of this embodiment is configured such that one step of driving of the sub-pointer motor 17 corresponds to the movement of the sub-pointer 2 in one minute. Since the sub pointer motor 17 is driven by 60 x 12 = 720 pulses, the first and second counters 22 and 23 are both 72
It is configured as a 0-base amplifier down counter.

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

However, the circuit in Figure 3 operates with positive logic, and simply H
or L indicates that it is logically at H level or L level, respectively.

First, as shown in FIG. 1, when the first crown 3 is set to the normal position 3a (switch SI is in the OFF state) and the device is in the normal carrying state, the sub hand 2 is set at the alarm cent time. The fact that the sub hand 2 is displaying the alarm set time means that the content of the second counter 23 is zero, that is, the second zero detection circuit 25 This means that the output of the inverter 35 is H, and the AND circuit 46 is in the ON state, so the
/60) Iz signal Φ4 is connected to the AND circuit 46 and O
It is input to the down-counting input terminal 22d of the first counter 22 via the R circuit 54. Therefore, in this state, the first counter 22 is decremented by 1 each time the signal Φ4 is supplied from the frequency division circuit 11 at one minute period. (However, as a special condition, the first
Immediately after the crown 3 is returned from the pulled-out position 3b to the normal position 3a, the content of the 20th counter 23 generally becomes zero immediately, and the second zero detection occurs, even though the crown 3 is in the normal position. Although the output of the circuit 25 does not necessarily become H, the operation in that case will be described later as an operation when switching the display of the sub pointer 2, and the explanation will be omitted here. ) On the other hand, when the first crown is in the normal position 3a and the second crown is also in the normal position 4a as described above, both the switches Sl and St are in the OFF state, so the INH circuit 34 is turned off. The output side is H. Therefore, when the alarm cent time reaches 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 becomes O.
The N state is entered, and the 2048 Hz signal from the frequency dividing circuit 6 is input to the buzzer drive circuit 26 via the AND circuit 57, and as a result, the buzzer 2 provided as an alarm element is activated.
7, an alarm notification sound will be generated.

That is, in this embodiment, the first and second crowns 3
．． 4 are set at their normal positions, the first zero detection circuit 24 detects that the contents of the first counter 22 have become zero (that the display position of the sub-hander 2 coincides with the time). detects that the alarm set time has arrived, and the buzzer 2 is activated based on the detection result.
7 to generate an alarm sound.

Furthermore, when the first crown is in the normal position 3a and the sub pointer 2 is displaying the alarm cent time, if the second crown is set to the pulled out position 4b, the switch S2 is turned on, so the INH circuit is turned on. The output side of the AND circuit 33 becomes H, and the output side of the AND circuit 37 also becomes H. Therefore, when the second crown 4 is rotated in the right (or left) direction in this state, the switch S3 turns on to the terminal a (or b), and the correction signal Φ2 from the frequency dividing circuit 6 changes to A.
The sub pointer motor 17 and the sub pointer are input to the forward rotation signal forming circuit 20 (or the reverse signal forming circuit 21 via the AND circuit 49 and OR circuit 52) through the ND circuit 48 and the OR circuit 51. 2 is corrected and driven in the forward (or reverse) direction according to the correction signal Φ2.

In this case, the correction signal Φ2 outputted via the AND circuit 48 (or 49) when the second crown 4 is rotated in the right (or left) direction is
) to the amplifier 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 also count up (or down) in accordance with the correction signal φ2. count) will be corrected.

Furthermore, as mentioned above, the first crown is in the normal position 3a,
When the second crown is in the pulled out position 4b, the output side of the INH circuit 34 is at L and the AND circuit 57 is in the OFF state. Even if the output side becomes H, the buzzer 27 will not generate an alarm sound. That is, in this embodiment, if the second crown 3 is set to the pulled out position 4b, the alarm function is controlled to be in the OFF state.

On the other hand, when the first crown 3 is set to the pulled out position 3b 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 crown 3 to the main pointer 1 or by high-speed drive of the main pointer motor 10.) However, in this embodiment, this method is used. When the first crown is set to the pulled out position 3b (switch S3 is set to O),
When the sub-phase hand 2 is placed in the N state), the sub-phase hand 2 is switched to the time display state.

First, in the initial state where the first crown 3 is set to the pulled out position 3b, the content of the first counter 22 is generally not zero, so the output side of the first zero detection circuit 24 is L.
Therefore, the INH circuits 41 and 42 are turned on. Therefore, in this state, the 64 Hz display switching signal Φ from the frequency dividing circuit 6 is input to the reverse signal forming circuit 21 via the INH circuit 41 and the OR circuit 52, and as a result, the sub-phase needle motor 17 And the sub-phase needle 2 is driven at high speed in the reverse direction. The display switching signal Φ outputted via the INHNH4I is also applied to the down-counting input terminal 22d of the first counter 22 and the up-counting input terminal 23u of the second counter 23 via the OR circuits 54 and 55. Because of the input, the counter 22 and the second counter 23 count down and count up, respectively, in synchronization with the high-speed movement of the sub-phase hand 2 in the reverse direction. Note that when a signal is output from the accessory bone circuit 11, the signal is sent to the INH circuit 4.
2 and the OR circuit 54 to the down-counting input terminal 22d of the first counter 22, in this state, the first counter 22 can also down-count in response to the signal from the accessory circumferential circuit 11. become. (However, the second
crown 4 is in the normal position 4a and switch S2 is in the O position.
When in the FF state, the output of the INH circuit 31 becomes H and the INH circuit 7 is controlled to be in the OFF state.
The IHz signal from the frequency division counter 6 is cut off, and no signal is actually output from the accessory bone rotation 11. ) As a result of the above, when the display of the sub-phase hand 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.
42 is turned off, and high-speed driving of the sub-phase needle motor 17 and the sub-phase needle 2 in the reverse direction is also stopped. That is, the content of the first counter 22 becomes zero, and the first zero detection circuit 24
When the output becomes H, it is determined that the switching of the sub-phase hand 2 to the time display state is completed.

The above is the operation when the first crown 3 is moved from the normal position 3a to the pulled-out position 3b, but more specifically, the operation when the first crown 3 is set to the pulled-out position 3b is , the second crown 4 is in the normal position 4a
Since there are differences depending on whether the position is set to 4b or the pull-out position 4b, the differences will be explained below.

First, when the second crown 4 is set to the normal position 4a (switch S2 is in the OFF state), the INH
Since the output side of the circuit 31 is L, when the output of the first zero detection circuit 24 is H and the switching of the sub-phase hand 2 to the time display state is completed, the output side of the AND circuit 36 is The signal becomes H, and the frequency dividing circuit 6 is held in the recent state.

That is, in the watch of this embodiment, the first crown 3
The main hand 1 is configured to stop moving every second only when the crown is set at the pulled out position 3a and the second crown 4 is set at the normal position 4a. Furthermore, in this state, the time displayed by the main hand 1 can be corrected by rotating the first needle 3, just as in the case of a well-known hand display type electronic timepiece.

On the other hand, as shown in FIG. 2, the second crown 4 is set to the pulled out position 4b (when the switch St is in the ON state → ANI), and the output side of the circuit 32 is at H. When the output of the first zero detection circuit 24 becomes H and the switching of the sub-phase hand 2 to the time display state is completed, the output side of the AND circuit 38 is also controlled to be H. Therefore, if the second crown 4 is rotated in the right (or left) direction in this state, the switch S will open the terminal a (or b
), and the correction signal Φ2 from the frequency dividing circuit 6 passes through the AND circuit 44 and the OR circuit 51 to the normal rotation signal forming circuit 20 (or the AND circuit 45 and the OR circuit 5).
2 to the reversal signal forming circuit 21), the sub-phase needle motor 17 and the sub-phase needle 2 receive the correction signal Φ
Correct drive is performed in the forward (or reverse) direction in accordance with 2.

In this case, the correction signal Φ2 outputted via the AND circuit 44 (or 45) when the second crown 4 is rotated in the right (or left) direction is
) to the down-count input terminal 23d (or up-count input terminal 23a) of the second counter 23, the time displayed by the sub-phase hand 2 advances (or lags). If modified,
The contents of the second counter 23 are also corrected by counting down (or counting up) in accordance with the correction signal Φ2.

In other words, if there is a discrepancy between the display position of the sub-phase hand 2 and the time displayed by the main hand 1 when the first glue user 3 is in the pulled-out position 3b and the sub-phase hand 2 is displaying the time. By rotating the second crown 4 in the pulled-out position 4b, it is possible to match the time displayed by the sub-phase hand 2 with the time displayed by the main hand 1.

Furthermore, as mentioned above, when both the first and second crowns 3.4 are in the pulled out positions 3b and 4b, the main hand l continues to move every second as usual. If you first set the second crown 4 to the pulled-out position 4b and then set the first crown 3 to the pulled-out position 3b, the time on the secondary phase hand 2 will simply be changed without affecting the main hand 1 at all. It is also possible to check the display position in the display state and to adjust the display time of the main hand 1.

Further, as described above, when both the first and second crowns 3.4 are in the pulled out positions 3b and 4b, and the output of the first zero detection circuit 24 is H, 5, the time display state of the sub-phase hand 2 is In the state where the switching is completed, the output side of the AND circuit 38 becomes H and the AND circuit 43 is in the ON state, so that the signal Φ4 with a period of 1 minute from the accessory circumferential circuit 11 is
is input to the forward rotation signal forming circuit 20 via the AND circuit 43 and the OR circuit 51, and as a result, the sub-phase hand 2 is also moved in accordance with the passage of time. In that case, AN
The signal Φ4 outputted from the D circuit 43 is sent to the down-counting input terminal 2 of the second counter 23 via the OR circuit 56.
3d, the second counter 23 performs a down-count operation in accordance with the movement of the sub-phase hand 2 in one-minute cycles.

Next, the operation when the first crown 3 is returned from the pulled out position 3b to the normal position 3a will be described.

First, since the switch SL is in the OFF state, the output side of the inverter 35 becomes H. In this case, the first state is
Generally, the content of the second counter 23 is not zero, so the output side of the second zero detection circuit 25 is L, and I
The NH circuit 47 is turned on. Therefore, in this state, the 64Hz display switching signal Φ1 from the frequency dividing circuit 6 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-phase needle motor 17 and The sub-phase needle 2 is driven at high speed in the normal rotation direction. Further, the display switching signal Φyo outputted via the INH circuit 47 is transmitted to the up-counting input terminal 22u of the first counter 22 and the second
Since the input is also input to the down-counting input terminal 23d of the counter 23, the first counter 22 and the second counter 23 are
The amp counts and down counts respectively.

Furthermore, during this high-speed hand movement, the AND circuit 46 is
When the frequency division circuit 11 outputs a signal Φ4 of one division period because it is in the N state, the signal is outputted to the AND circuit 4.
6 and the OR circuit 54 to the down-counting input terminal 22d of the first counter 22. Therefore, in this state, the first counter 22 can also down-count in response to the signal from the frequency dividing circuit 11. become.

As a result of the above, when the display of the sub-phase hand 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), I
The NH circuit 47 is turned off, and the sub-phase needle motor 17
The high-speed drive of the sub-phase needle 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-phase hand 2 to the alarm set time display state is completed.

〔Effect of the invention〕

As described above, in the watch of the present invention, as long as the first crown is carried in the normal position, the secondary phase hand maintains the display state of the alarm set time. Confirming the set time does not require any intervention, and adjusting the alarm set time is extremely easy as all you have to do is pull out the second crown and rotate it. It becomes easy to understand.

In the above embodiment, regardless of the axial position of the second crown 4, when the first crown 3 is set to the pulled out position 3b, the subphase hand 2 is controlled to the time display state. However, it is also possible to configure the secondary phase hand 2 to be controlled to the time display state only when both the first and second crowns 3.4 are set to the pulled out positions 3b, 4b. It is possible.
