Description

The present invention relates to an electronic timepiece and an electronic device that perform function setting using a crown.

2. Description of the Related Art Conventionally, a timepiece having a pointer and an operation member “Crown” is known. In such a watch, the crown is provided on the side of the watch body. When the crown is pushed in and returned (in the crown-returned state), the watch hands display the time, and the user pushes the crown. When pulled (the crown is pulled), the second hand of the watch stops and the hour and minute hands can be corrected by rotating the crown.
In recent years, a timepiece having various functions other than the hour / minute hand correction, that is, a timepiece capable of displaying these functions or setting related to these functions by operating the crown has been developed. For example, the hour / minute and second hands of the watch display the time when the crown is in the “retracted state”, but the second hand of the watch is “standard radio wave reception set or not set” It is a clock that displays "?". The user can set or cancel the standard radio wave reception function by rotating the crown in the “crown pulling state”.

The following techniques are disclosed in response to the increase in the number of functions of the crown. In Patent Document 1, when the crown is changed from the two-step pulling state to the one-step pulling state in the two-step pulling crown (two-step pulling state / one-step pulling state / zero-step pulling state (crown return state)). In order to prevent accidental entry into the zero-pull state, a technique is disclosed in which the crown input is invalidated for a certain period after passing from the two-pull state to the one-pull state.
In Patent Document 2, when the crown is pulled to the first stage for mode switching, a warning is displayed by means such as stopping the second hand at the 30-second position, and mode erroneous switching due to forgetting to push the crown is possible. A technique for reducing the performance is disclosed.

By the way, when the function display contents indicated by the second hand are different in the “returning state” (zero pulling state) and the “crown pulling state” (one step pulling state), the following problems exist.

For example, it is assumed that when the crown is pulled, the mode changes to the standard radio wave reception setting mode. Specifically, when the crown is pulled, the function of the second hand changes from the second hand to turn on / off the standard radio wave reception setting, and turning the crown turns the standard radio wave reception setting on / off. Is assumed to be switched. In such a case, if the crown rotates accidentally when the crown is returned, the setting display of the second hand is not displayed and the second display is switched to the normal display state. There was a problem that the setting information that was not displayed.

In particular, the problem in the case of the “screw lock crown” is remarkable. The screw lock crown is a “crown” used to improve waterproofness. The crown is partly screwed and when not operated, it is screwed onto a predetermined part of the watch body. First, the user first turns the screw, for example, to loosen it, makes it ready for pulling (still in the zero-pull state), pulls the crown, and shifts to the standard radio wave reception mode. When the operation in the standard radio wave reception mode is completed, the user returns the crown, and then tightens the screw. However, when the crown is returned, the screw lock operation is performed, that is, the rotating operation and the returning operation may be performed at the same time, and the second hand returns to the second display of the time. There was a problem that the setting information was not recognized.

The objective of this invention is providing the electronic device which can confirm the setting content in a 2nd display state in operation to transfer from a 2nd display state to a 1st display state .

In order to achieve the above object, the present invention
A rotary switch capable of pulling / returning operation in the axial direction and rotating operation in the pulled state, setting changing means for changing the setting of validity / invalidity of the function by rotating the rotary switch, and setting by the setting changing means Display state holding means for causing the display of the second display state to be performed after holding the display of the second display state for a predetermined period of time from the second display state that displays the changed state display to the first display state that displays the time. It is an electronic timepiece characterized by comprising.

According to the present invention, it is possible to provide an electronic device that can confirm the setting contents in the second display state caused by an erroneous operation even if the switch is operated by mistake.

That is, the magnetic sensor 15 has a phase difference in the output when detecting the change in the magnetic field accompanying the rotation of the magnet member 14 due to the difference in the installation positions of the two magnetoresistive elements 15a and 15b. By outputting two types of detection signals based on the phase difference, the rotation of the magnet member 14 is detected. In this case, the two types of detection signals are transmitted to the rotation detection unit 50

Next, operations relating to the crown / return process of the electronic timepiece 100 configured as described above will be described with reference to FIGS.

FIG. 12 shows an operation of switching the ON / OFF of the reception setting by operating the crown 10 to shift from the time display function to the standard radio wave reception function (hereinafter referred to as the standard radio wave reception mode) which is another function status display. It is explanatory drawing which shows the conventional example of.

Here, the ON state of the standard radio wave reception setting is a state in which the standard radio wave reception function is set and enabled. In this state, for example, a standard radio wave is received once a day to correct its own time. Specifically, the CPU 40 executes a program of “correction processing using standard radio waves” stored in the ROM 42 and activates the radio wave receiving unit 41 when a predetermined time (for example, 12:00 pm) is reached, so that the standard radio waves are transmitted. A radio wave reception process for receiving and receiving the time code, and an automatic time correction process for determining the acquired time code and correcting the time data of the time measuring circuit 47 are performed. On the other hand, the OFF state of the standard radio wave reception setting is a state where the standard radio wave reception function is canceled and disabled.

In FIG. 12A, the crown 10 is in the returned state, and the pointer indicates the “first display state” (time display function). That is, the second hand 31, the minute hand 32, and the hour hand 33 all indicate time. FIG. 12B shows a state where the crown 10 is pulled (a state where the crown is pulled). In this case, the second hand 5 displays the standard radio wave reception mode which is the “second display state”. FIG. 12 (B)
Then, the second hand 31 points the “ON” character on the outer periphery of the dial 7. This indicates that the standard radio wave reception setting is valid (hereinafter referred to as “ON” state). On the other hand, the minute hand 32 and the hour hand 33 continue to display the time.

In FIG. 12B, when the user rotates the crown 10 by 90 degrees clockwise, for example, the standard radio wave reception setting is changed from valid (ON state) to invalid (hereinafter referred to as “OFF” state). The second hand 31 is displaced from the ON position to the OFF position at a speed of 32 steps / second. FIG. 12C shows a state after the second hand 31 is displaced to the OFF position.

A case where the user pushes in the crown 10 will be described with reference to FIG. When the crown 10 is pushed in, as shown in FIG. 12D, the state returns to the “first display state” (time display function). In other words, the second hand is displaced from the instructed set value (OFF position in FIG. 12C) to a position indicating the current second at a speed of 32 steps / second.

However, if the crown 10 is accidentally rotated when the crown 10 is pushed in and returned, the standard radio wave reception setting is changed from OFF to ON. In particular, in the case of a screw lock crown, it may be pushed while turning in an attempt to operate at once. Even in that case, as shown in FIG. 12D, the second hand returns to the “first display state” (time display function) without displaying the “second display state” (standard radio wave reception mode). End up. Therefore, when the crown 10 is not rotated at the time of returning, the state shown in FIG.
The determination of FIG. 12E that has changed to N cannot be made.

FIG. 13 is a timing chart showing the situation of the crown and the hand corresponding to FIG.
The upper part of FIG. 13 shows the position of the crown in the axial direction. The crown pulling state is shown as signal high (H), and the crown return state is shown as signal low (L). In addition, in the switch part 51, the contact spring part 22a is in contact with the contact part 25b in the crown pulled state, and the contact spring part 22a is in contact with the contact part 25a in the returned state. The middle part of FIG. 13 shows the presence or absence of the crown rotation. That is, based on the output of the rotation detector 50, a pulse signal is output when the crown is rotated. The lower part of FIG. 13 shows the status of the pointer.

In FIG. 13, the crown is initially in the retracted state, and the signal indicates L. The hands indicate the time (first display state). When the user pulls the crown 10, the crown is pulled and the signal changes from L to H. When the signal H is detected, the display mode of the second hand 31 is changed to the standard radio wave reception mode, and the second hand 31 indicating the second is displaced to the standard radio wave reception ON position at a speed of 32 steps / second. When the user rotates the crown 10 by 90 degrees clockwise, the output of the rotation detecting unit 50 in FIG. 1 becomes H, and the second hand 31 is displaced from the ON position to the OFF position.

Next, the user tries to return the crown 10. When returning it while turning it by mistake, a crown rotation signal is output, and the CPU 40 changes the standard radio wave reception setting from OFF to ON. However, since the crown is returned almost simultaneously with the rotation of the crown, the second hand 31 shifts to the time display function. In this way, if the crown 10 is accidentally rotated when the crown 10 is returned, the “incorrectly set state” by the user is not displayed.

FIG. 14 is an explanatory diagram illustrating an operation of switching the reception setting ON / OFF by operating the crown 10 to shift to the standard radio wave reception setting mode according to the embodiment of the present invention. FIG.
4 (A) to (C) correspond to FIGS. 12 (A) to (C). 14A shows the first display state (time display function) when the crown 10 is in the returned state, and FIG. 14B shows the state in which the second hand 31 is in the standard radio wave reception “ON” state. ) Shows a display after the user changes the setting from the standard radio wave reception “ON” state to the standard radio wave reception “OFF” state.

Here, a case where the user returns the crown 10 to shift to the time display function will be described. In the present embodiment, approximately 1 is required when shifting from the “retracted state” to the “returned state”.
The second hand 31 is configured to hold the display state in the crown pulled state for a second.
Therefore, when the user accidentally rotates the crown 10, as shown in FIG. 14D, the second hand 31 is displaced from the standard radio wave reception OFF state to the standard radio wave reception ON state, and about one second has elapsed. Then, as shown in FIG. 14E, the mode is shifted to the clock display mode. Thus, even if the crown 10 is accidentally rotated when the crown 10 is returned, the user can confirm the “incorrectly set state” on the display.

FIG. 15 is a timing chart showing the situation of the crown and the hand corresponding to FIG. 14 according to the embodiment of the present invention. In FIG. 15, (A) to (C) correspond to (A) to (C) in FIG. When the user tries to return the crown 10 after FIG. 15 (C), if the user rotates it by mistake, a crown rotation signal is output as shown in the middle of FIG.
40 changes the standard radio wave reception setting from OFF to ON.

In the present embodiment, approximately 1 is required when shifting from the “retracted state” to the “returned state”.
The second hand 31 is configured to hold the display state in the crown pulled state for a second.
Therefore, even if the crown rotates accidentally when the crown 10 is returned, the second hand 3
1 displays the standard radio wave reception mode for about 1 second, and the user can confirm that the set state has changed. Therefore, the user can correct the setting later.

FIG. 16 shows a flowchart of the crown pulling / returning process according to the embodiment of the present invention. The operation of the electronic timepiece 100 relating to the “crown pulling / returning process” will be described with reference to the flowchart of FIG.

When the “crown pull / return process” is started, the CPU 40 first determines whether or not the crown 10 has shifted from the pulled state to the returned state (step S1). Specifically, the CPU 40 determines whether the signal derived from the switch unit 51 has changed from the signal H (pulling state) to the signal L (returning state). If it is determined that the state has shifted, the process branches to “YES” in step S1, and the display of the second hand is held for about 1 second in the standard radio wave reception mode (second display state) (step S2).
). Then, the time is indicated (first display state) (step S3), and the "crown pulling / returning process" is ended. Here, the CPU 40 and steps S1 and S2 are display state holding means. The CPU 40 and step S3 are display control means.

On the other hand, when branching to “NO” in step S1, the CPU 40 determines whether or not the crown 10 has shifted from the returned state to the pulled state (step S4). If it is determined that the signal has shifted, the process branches to “YES” in step S4, shifts to the standard radio wave reception mode (step S5), and the second hand indicates ON / OFF of the standard radio wave reception setting (step S6). Thereafter, the “rewind / return process” is terminated. Here, the CPU 40 and steps S5 and S6 are display control means.

If there is no change in the crown / return state at step S4, "NO"
The CPU 40 terminates the “retract / return process” as it is.

FIG. 17 shows a flowchart of the crown rotation process according to the embodiment of the present invention. The operation of the electronic timepiece 100 relating to the “crown rotation process” will be described with reference to the flowchart of FIG.

When the “crown rotation process” is started, the CPU 40 first determines whether or not the current display is the standard radio wave reception mode (second display state) (step S10). If it is determined that the current display is the standard radio wave reception mode (second display state), “YES” in step S10.
To determine whether or not the crown has been rotated (step S11). If it is determined that the crown has been rotated, the process branches to “YES” in step S11, and the CPU 40 changes the ON / OFF state of the standard radio wave reception setting and displaces the second hand 31 to the corresponding hand position. (Step S12).

If branching to "NO" in step S10 or step S11, the crown rotation process is terminated. Here, the CPU 40 and steps S10 to S12 are setting change control means.

As described above, in the electronic timepiece 100, the transition from the second display state to the first display state by the crown is performed after holding the display of the second display state for a predetermined period. It is possible to provide an electronic timepiece capable of confirming the setting contents in the second display state caused by erroneous rotation even if the is rotated.

Further, the display unit is composed of a timepiece dial and a pointer, and the pointer for displaying the second display state is the second hand, so that different functions can be displayed with the second hand.

The present invention is not limited to the above-described embodiment, and various modifications can be made.
For example, in the present embodiment, the display unit displays the “second display state” with the second hand, but is not limited thereto. A minute hand or an hour hand may be used. Further, the display unit is not a needle type, and may be a display unit configured by a display element such as a liquid crystal display or an organic EL display. In this case, the display unit displays the “first display state” and the “second display state” on the display unit sequentially in time corresponding to the “return state” and the “retractor state”. Have

In this case, since the display on the display unit can be performed by a liquid crystal display element, the crown can also be used in digital display.

In the present embodiment, the crown 10 has two step positions, that is, a crown pulling state (one-stage pulling state) and a crown returning state (zero-stage state). You may have. In this case, it suffices if the return state of the crown and the pulling state of the crown corresponding to the present embodiment are adjacent to each other.

In this case, the crown can be moved in three or more stages in the axial direction, and it is sufficient that the crown is pulled back and the pulling state of the crown is an adjacent stage. It is also possible to do.

In this embodiment, the standard radio wave reception setting has been described as an example of the “second display state”. However, the “second display state” by the crown is not limited thereto, and for example, an alarm O
N / OFF may be set. In this case, the alarm function is another function.
It means that the alarm setting is ON, and “invalid” means that the alarm setting is OFF. In addition, even other functions can be applied as other functions of the present invention as long as they can be selectively switched.

In this case, since the standard radio wave reception function or the alarm notification function is used as another function, the electronic timepiece can confirm the setting contents in the second display state caused by erroneous rotation with these functions as the second display state. Can be provided.

In the present embodiment, the rotation detection unit 50 of the crown 10 outputs only one pulse when the crown is rotated 90 degrees, and the setting is ON, for example, when the crown is rotated only in one direction. Then, when it is further rotated 90 degrees and rotated 180 degrees, further pulses are generated and the setting is turned OFF, for example, but the rotation angle for outputting one pulse is not limited to 90 degrees, and may be 45 degrees, for example. Further, as another configuration, for example, when the clockwise rotation direction is rotated by a predetermined angle, the setting is changed from OFF to ON, for example, and when the counterclockwise rotation is performed, the setting is changed from ON to OFF, for example. You can also.

In the present embodiment, the case where the rotation of the crown 10 is detected magnetically as the crown portion 6 is shown, but the present invention is not limited to this. For example, the rotation of the crown 10 may be detected optically by a photo interrupter. Further, the rotation of the crown 10 may be detected using a mechanical contact.

Although the embodiment of the present invention has been described, the scope of the present invention is not limited to the above-described embodiment, and is included in the invention described in the claims and the equivalent scope thereof. Hereinafter, the invention described in the scope of claims of the present application will be appended.
