However, in the above-mentioned prior art, for example, the time zone option that can be manually set is limited to the time zone that can be automatically set based on the current position of the electronic clock, and the time zone can be set flexibly. There is a problem that it cannot be done.

For example, in the map data in the electronic clock, if a certain time zone is not associated with any region, the time zone is not automatically set based on the current position of the electronic clock. Some users may want to use that time zone. As an example, if there was a region that was adopted in the past, but the time zone of that region was changed and there is a time zone that no longer exists, the user in that region will be able to use that region. You may want to use the previous time zone of. However, the conventional electronic clock has a problem that it is not possible to set a time zone that is not associated with any area in the map data.

It is an object of the present invention to provide an electronic timepiece capable of flexibly setting a time zone in order to solve the above-mentioned problems caused by the prior art.

In order to solve the above-mentioned problems and achieve the object, the electronic clock according to the present invention is an electronic clock having a dial, a pointer that rotates on the dial to indicate a time, and an operation unit. , Time zones are sequentially provided along the periphery of the dial, and the time zone display unit indicated by the pointer, the correspondence information between the position and the time zone, and the time zone based on the position of the own device are set, or A setting unit for setting a time zone based on a user operation of the operation unit and a notification unit for notifying a user of a time based on the time zone set by the setting unit are provided, and a time provided in the time zone display unit is provided. The zone includes a first time zone that can be set based on the correspondence information between the position and the time zone and the position of the own device, and a second time zone that can be set based on the user operation of the operation unit. Including, the number of the second time zones is larger than the number of the first time zones.

As a result, even a time zone different from the time zone that can be automatically set according to the position of the electronic clock can be set by the user operation.

According to one aspect of the present invention, there is an effect that the time zone can be flexibly set.

Hereinafter, embodiments of the electronic clock according to the present invention will be described in detail with reference to the drawings.

(Embodiment 1)
(Appearance of Electronic Clock According to Embodiment 1)
FIG. 1 is a diagram showing an example of the appearance of the electronic clock according to the first embodiment. As shown in FIG. 1, the electronic clock 100 according to the first embodiment has a dial 110 arranged in a body which is an exterior (clock case), and an hour hand 121, a minute hand 122, and a second hand which are pointers indicating a time. It includes 123 and a small window 160. The exterior of the electronic clock 100 may be composed of a bezel and a body.

The hour hand 121, the minute hand 122, and the second hand 123 are pointers that display the time according to their relative positions with respect to the dial 110. Further, the second hand 123 may also be used for displaying information different from the time. The small window 160 has a pointer 161 and displays information different from the time by the pointer 161.

Further, in the electronic watch 100, a crown 131 (crown), a first push button 132, and a second push button 133 are arranged on the side surface of the body as an operation unit 130 for the user of the electronic watch 100 to perform various operations. ing. In the example shown in FIG. 1, the crown 131 is arranged on the 3 o'clock side, the first push button 132 is arranged on the 2 o'clock side, and the second push button 133 is arranged on the 4 o'clock side.

A windshield made of a transparent material such as glass is attached to the body of the electronic clock 100 so as to cover the dial 110. Further, a back cover is attached to the body of the electronic clock 100 on the opposite side of the windshield. Hereinafter, the direction in which the windshield is arranged in the electronic timepiece 100 (the direction toward the front of the paper in FIG. 1) is referred to as the front side, and the direction in which the back cover is arranged in the electronic timepiece 100 (the direction in the back of the paper in FIG. 1) is referred to as the back side.

Further, the electronic clock 100 is a solar cell clock powered by light energy such as the sun. For example, a solar cell 343 (see, for example, FIG. 3) described later is arranged on the back side of the dial 110, and the solar cell 343 generates electricity by the light received from the front side. Therefore, the dial 110 is made of a material that transmits light rays to some extent.

Further, the electronic clock 100 receives satellite radio waves including time information related to the date and time from the satellite, and based on the time information included in the received satellite radio waves, the internal time is information on the time held inside the wristwatch. It is a satellite radio-controlled wristwatch that corrects. The satellite is, for example, a GPS satellite. GPS is an abbreviation for Global Positioning System (Global Positioning System). For example, an antenna 310 (see, for example, FIG. 3) described later for receiving satellite radio waves is arranged in a region of the electronic clock 100 that does not overlap with the solar cell 343. The front surface of the antenna 310 is a receiving surface for receiving radio waves from the satellite. The receiving surface of the antenna 310, the light receiving surface of the solar cell 343, and the dial 110 are provided in parallel with each other, and all face the front side.

Further, in the electronic clock 100, around the dial 110, there are a reception success character 141 which is a character of "OK", a reception failure character 142 which is a character of "NO", and a character of "RX-GPS". The positioning character 143 and the time measuring character 144, which is the character of "RX-TIME", are represented.

The reception success character 141 and the reception failure character 142 are indexes for indicating the success or failure of the result of the reception processing of the satellite radio wave by the electronic clock 100 by using the second hand 123. Further, the time measurement character 144 is an index for displaying that the time measurement reception operation is in progress by using the second hand 123 when the time measurement reception operation is performed by the electronic timepiece 100. The time measurement reception operation is an operation of correcting the internal time of the electronic clock 100 based on the time information included in the satellite radio wave. Further, the positioning character 143 is an index for displaying that the positioning reception operation is in progress by using the second hand 123 when the positioning reception operation is performed by the electronic clock 100.

In the positioning reception operation, the time information included in the satellite radio wave is acquired, and the position information (positioning information) of the observation point is calculated based on the distance between the plurality of satellites and the observation point (electronic clock 100), and the positioning information is obtained. This is an operation of correcting the internal time of the electronic clock 100 to the time information of the current position based on the map data of the electronic clock 100 and the map data of the electronic clock 100. The positioning information includes, for example, information regarding the latitude and longitude of the current position.

The map data has a time zone corresponding to the current position. As the time zone, a value based on UTC or GMT (Greenwich Mean Time) can be used. For example, the world map is subdivided into predetermined latitudes and longitudes, and time difference information is given to each subdivided area. If a plurality of time differences are included in the subdivided region, the subdivided region may be further subdivided. The map data is the correspondence information between the area defined in this way and the time difference information. Further, the map data is stored in, for example, ROM 332, which will be described later. Further, the map data may include information such as a city name representing the current position, applicability of daylight saving time, start / end time of daylight saving time, and the type of GNSS (Global Navigation Satellite System / global positioning satellite system) that can be received.

Further, a time zone display unit 150 is provided on the dial ring around the dial 110. In the example shown in FIG. 1, the time zone display unit 150 has 60 notations (for example, markings) corresponding to 60 different time zones. Further, on the outer periphery of the time zone display unit 150, main time zones such as "+1", "+2", and "+3" are written. For example, a time zone display unit 150 indicating "0" is written at a position corresponding to "0 seconds" on the dial 110. Further, a time zone display unit 150 indicating "+1" is written at a position corresponding to "2 seconds" on the dial 110.

For example, the user performs a positioning reception operation by pressing and holding the first push button 132 for a few seconds. In this case, by pressing the first push button 132, for example, the second hand 123, which has been ticking the seconds, temporarily leaves the normal timekeeping operation and points to the positioning character 143.

Further, the user performs a time measurement reception operation by pressing and holding the second push button 133 for several seconds. In this case, by pressing the second push button 133, for example, the second hand 123, which has been ticking the seconds, temporarily leaves the normal timekeeping operation and points to the timekeeping character 144.

The operation on the electronic clock 100 is not limited to these. For example, the positioning reception operation may be executed by pressing the first push button 132 twice in succession. Alternatively, an operation using other than the first push button 132 and the second push button 133, for example, an operation of the crown 131 may be used to instruct a positioning reception operation or a timed reception operation. Further, the electronic clock 100 may be provided with a touch sensor and operated by the touch sensor. In addition, light or magnetic operation may be used.

The appearance of the electronic clock 100 shown in FIG. 1 is an example, and the appearance of the electronic clock 100 is not limited to this. For example, the body may be square instead of round, and the presence / absence, number, and arrangement of crown 131 and the like can be arbitrarily changed. Further, the pointer is not limited to the configuration including the hour hand 121, the minute hand 122, and the second hand 123, and the second hand 123 may be omitted, for example. Alternatively, the day of the week, the presence or absence of daylight saving time, the reception status of radio waves, the remaining battery level, guidelines for various displays, date display, and the like may be added.

(Type of each time zone in the electronic clock according to the first embodiment)
FIG. 2 is a diagram showing an example of a type of each time zone in the electronic timepiece according to the first embodiment. In FIG. 2, the same parts as those shown in FIG. 1 are designated by the same reference numerals and the description thereof will be omitted. The time zone display unit 150a (shown in white) shown in FIG. 2 indicates each time zone that can be automatically set based on the current position of the electronic clock 100 among the time zone display units 150 shown in FIG. There is. Further, each time zone indicated by the time zone display unit 150a can be manually set. Each time zone indicated by the time zone display unit 150a includes, for example, "0", "+1", "+2" and the like.

The time zone display unit 150b (shown by hatching) shown in FIG. 2 is not automatically set based on the current position of the electronic clock 100 among the time zone display units 150 shown in FIG. 1, but can be set manually. Indicates the time zone. Although the time zone display unit 150b is shown by hatching in FIG. 2, the appearance of the time zone display unit 150b may be the same as that of the time zone display unit 150a as shown in FIG. Each time zone indicated by the time zone display unit 150b includes "-4.5" and "+10.5" in the example shown in FIG.

For example, each time zone indicated by the time zone display unit 150b has a region (for example, a country) that has been adopted in the past, but the time zone of that region has been changed and the region to be adopted no longer exists. It is a zone. Such a time zone is not automatically set based on the current position of the electronic clock 100, but some users may want the electronic clock 100 to display the time according to this time zone.

On the other hand, in the electronic clock 100, in addition to the time zone that can be automatically set (for example, each time zone of the time zone display unit 150a), the time zone that is not automatically set (for example, each time zone of the time zone display unit 150b). ) Is a time zone that can be set manually. As a result, the user can manually set a time zone that is not automatically set based on the current position of the electronic clock 100, and a flexible time zone can be set.

The time zone display unit 150c (shown in black) shown in FIG. 2 indicates each time zone of the time zone display unit 150 shown in FIG. 1 that cannot be set automatically or manually. Although the time zone display unit 150c is shown in black in FIG. 2, the appearance of the time zone display unit 150c may be the same as that of the time zone display unit 150a as shown in FIG. Each time zone indicated by the time zone display unit 150c includes, for example, "+0.5", "+1.5", "+2.5" and the like.

Further, whether the setting is manual only or whether manual or automatic can be set may be switched according to the internal time of the electronic clock 100. As an example, a certain time zone can be automatically selected until December 31, 2017, but after January 1, 2018, the time zone may be set only manually. As a result, for example, when the map data update data is acquired in advance and the map data is updated at a certain time (January 1, 2018, for example), the setting is manual only or both manual and automatic are set. It can also be automatically switched whether it is possible.

(Hardware configuration of the electronic clock according to the first embodiment)
FIG. 3 is a diagram showing an example of the hardware configuration of the electronic timepiece according to the first embodiment. As shown in FIG. 3, the electronic clock 100 according to the first embodiment includes an antenna 310, a receiving circuit 320, a control circuit 330, a secondary battery 340, a switch 342, a solar cell 343, and a drive mechanism 350. And, it is realized by the time display unit 351 and the operation unit 360.

The antenna 310 receives a satellite radio wave transmitted from the satellite as a radio wave including time information. For example, the antenna 310 is a patch antenna that receives satellite radio waves transmitted from GPS satellites. However, the antenna 310 is not limited to the patch antenna, and may be, for example, a chip antenna or an inverted F antenna.

The receiving circuit 320 decodes the satellite radio wave received by the antenna 310 and outputs a bit string (received data) indicating the content of the satellite radio wave obtained as a result of the decoding. For example, the receiving circuit 320 includes a high frequency circuit 321 (RF circuit) and a decoding circuit 322.

The high frequency circuit 321 is an integrated circuit that operates at a high frequency. For example, the high frequency circuit 321 converts the analog signal received by the antenna 310 into a baseband signal by amplifying and detecting the analog signal received by the antenna 310.

The decoding circuit 322 is an integrated circuit that performs baseband processing. For example, the decoding circuit 322 decodes the baseband signal output by the high frequency circuit 321 to generate a bit string indicating the content of the data received from the GPS satellite. Then, the decoding circuit 322 outputs the generated bit string to the control circuit 330.

The control circuit 330 includes a calculation unit 331, a ROM 332, a RAM 333, an RTC 334, and a motor drive circuit 335. ROM is an abbreviation for Read Only Memory. RAM is an abbreviation for Random Access Memory (random access memory). RTC is an abbreviation for Real Time Clock. The control circuit 330 can be realized by an information processing device such as a microcomputer.

The arithmetic unit 331 performs various information processing according to the program stored in the ROM 332. The details of the processing executed by the calculation unit 331 will be described later. The RAM 333 is used as a work memory of the calculation unit 331, and data to be processed by the calculation unit 331 is written. For example, a bit string (received data) representing the contents of the satellite radio wave received by the receiving circuit 320 is sequentially written in the buffer area of the RAM 333. The RTC 334 supplies a clock signal used for timekeeping in the electronic clock 100.

Further, the ROM 332 stores map data (for example, see FIG. 4) that associates the position with the time zone. For example, the arithmetic unit 331 performs a positioning operation for specifying the current position of the electronic clock 100 based on a plurality of satellite information received by the receiving circuit 320. Then, the calculation unit 331 determines the time zone corresponding to the current position of the electronic clock 100 based on the determined current position of the electronic clock 100 and the map data stored in the ROM 332.

Further, the arithmetic unit 331 corrects the internal time measured by the signal supplied from the RTC 334 based on the time information included in the satellite radio wave received by the receiving circuit 320. Further, the calculation unit 331 determines the time (display time) to be displayed on the time display unit 351 based on the corrected internal time and the determined time zone.

The motor drive circuit 335 outputs a drive signal for driving the motor included in the drive mechanism 350, which will be described later, according to the display time determined by the calculation unit 331. As a result, the display time determined by the control circuit 330 is displayed on the time display unit 351.

The secondary battery 340 stores the electric power generated by the solar cell 343. Then, the secondary battery 340 supplies the stored electric power to the receiving circuit 320 and the control circuit 330. The secondary battery 340 can be realized by, for example, a lithium ion battery or the like.

A switch 342 is provided in the middle of the power supply path from the secondary battery 340 to the receiving circuit 320, and the on / off of the switch 342 is switched by the control signal output from the control circuit 330. For example, the operation timing of the receiving circuit 320 is controlled by switching the switch 342 on / off by the control circuit 330. In this case, the receiving circuit 320 operates only while the power is supplied from the secondary battery 340 via the switch 342, and decodes the satellite radio wave received by the antenna 310 during that time.

The solar cell 343 is arranged, for example, on the back side of the dial 110. Then, the solar cell 343 generates electric power by external light such as sunlight applied to the electronic clock 100, and supplies the generated electric power to the secondary battery 340.

The drive mechanism 350 includes a step motor that operates in response to a drive signal output from the motor drive circuit 335 described above, and a train wheel. The wheel train transmits the rotation of the step motor to the second hand. Rotate a pointer such as 123.

The time display unit 351 is composed of, for example, the pointer shown in FIG. 1 and the dial 110. The pointer includes an hour hand 121, a minute hand 122, and a second hand 123, and the current time is displayed by rotating these pointers on the dial 110. Further, as will be described later, the pointer (for example, the second hand 123) is assigned to display a plurality of types of information.

The operation unit 360 receives an operation by the user and outputs the operation content to the control circuit 330. The control circuit 330 executes various processes according to the contents of the operation input received by the operation unit 360. For example, the control circuit 330 performs satellite radio wave reception processing in response to an operation input to the operation unit 360 by the user. The operation unit 360 can be realized by, for example, the crown 131, the first push button 132, the second push button 133, and the like shown in FIG.

The data update module 361 updates the map data stored in the ROM 332 according to an operation from the outside of the electronic clock 100. For example, the data update module 361 has a non-contact communication interface for communicating by a change in a magnetic field via a coil (for example, a motor coil) provided in the electronic clock 100, and the map data stored in the ROM 332 can be stored in the non-contact communication interface. Update to the map data received by the contact communication interface.

Alternatively, the data update module 361 has a wired communication interface capable of wired communication with an external device of the electronic clock 100, and the map data stored in the ROM 332 is the map data received by the wired communication interface. Update to.

Alternatively, the data update module 361 has a wireless communication interface capable of wireless communication with an external device of the electronic clock 100, and the map data stored in the ROM 332 is the map data received by the wireless communication interface. You may update to. As this wireless communication interface, various wireless communication interfaces such as wireless LAN, bluetooth, and cellular communication can be used. Bluetooth is a registered trademark. LAN is an abbreviation for Local Area Network. Further, this wireless communication interface may be included in the antenna 310 and the receiving circuit 320.

In addition, the data update module 361 updates the map data, and notifies the user if there is a time zone that was included in the map data before the update but is not included in the updated map data. You may. This makes it possible to notify the user when there is a time zone that cannot be set due to the update of the map data. Alternatively, the data update module 361 may notify the user only when the time zone that cannot be set is the time zone that was set before the map data was updated.

In addition, the data update module 361 updates the map data and notifies the user if there is a time zone that was not included in the map data before the update but is included in the updated map data. You may. For example, the data update module 361 indicates by the second hand 123 between the added time zone and the existing time zone closest to the plus direction and the existing time zone closest to the added time zone and the minus direction. Notify by. This makes it possible to notify the user when a time zone that can be set only manually is added by updating the map data.

Further, the data update module 361 may notify the user when the map data is updated. Further, the data update module 361 may notify the user of the time (for example, year) when the map data is updated. Various notifications to the user by the data update module 361 can be realized, for example, by instructing the data update module 361 to control the predetermined time display unit 351 to the motor drive circuit 335.

In the electronic clock 100 shown in FIG. 3, the setting unit for setting the time zone can be realized based on the calculation unit 331, ROM 332, RAM 333, and RTC 334. Further, the notification unit for notifying the user of the time based on the time zone set by the setting unit can be realized by, for example, the motor drive circuit 335, the drive mechanism 350, and the time display unit 351.

(Map data of the electronic clock according to the first embodiment)
FIG. 4 is a diagram showing an example of map data included in the electronic clock according to the first embodiment. For example, the map data 400 shown in FIG. 4 is stored in the ROM 332 of the electronic clock 100 shown in FIG. The map data 400 is correspondence information that associates a position with a time zone.

The position of the map data 400 is, for example, the current position of the electronic clock 100 specified from the satellite signal received by the antenna 310 and the receiving circuit 320 shown in FIG. The time zone of the map data 400 is a time zone corresponding to the current position of the electronic clock 100.

The electronic clock 100 can determine the time zone corresponding to the current position of the specified electronic clock 100 from the map data 400. For example, when the current position of the electronic clock 100 is P1, it can be determined that the time zone corresponding to the current position of the electronic clock 100 is Z1.

In the example shown in FIG. 4, the case where the map data 400 is information that directly associates the current position of the electronic clock 100 with the time zone has been described, but the map data 400 describes the current position of the electronic clock 100 and the time zone. It may be information that is indirectly associated. For example, the map data 400 may be realized by a combination of information for associating the current position of the electronic clock 100 with a region (for example, a country) and information for associating a region with a time zone.

(Time zone setting process by receiving satellite radio waves of the electronic clock according to the first embodiment)
FIG. 5 is a flowchart showing an example of a time zone setting process by receiving satellite radio waves of the electronic timepiece according to the first embodiment. The electronic clock 100 according to the first embodiment executes each step shown in FIG. 5, for example, periodically or by an instruction (forced) from a user.

First, the electronic clock 100 receives satellite radio waves (step S501). Step S501 is executed, for example, by the antenna 310 and the receiving circuit 320 shown in FIG. Next, the electronic clock 100 identifies the current position of the electronic clock 100 based on the satellite radio wave received in step S501 (step S502). Step S502 is executed, for example, by the calculation unit 331 shown in FIG.

Next, the electronic clock 100 determines the time zone based on the current position and the map data specified in step S502 (step S503). Step S503 is executed by the calculation unit 331 shown in FIG. 3, for example, based on the map data stored in the ROM 332 shown in FIG. 3 (for example, the map data 400 shown in FIG. 4).

Next, the electronic clock 100 determines whether or not the time zone set in the own device is manually set (step S504). For example, when the time zone set in the own device is set by step S507 described later, the electronic clock 100 can determine that it is not set manually. Further, if the time zone set in the own device is not set by step S507 described later, the electronic clock 100 can determine that it is set manually.

For example, the electronic clock 100 may make a determination in step S504 based on whether or not information indicating that the time zone has been set based on the current position of the electronic clock 100 in step S507 is stored in the ROM 332 or RAM 333. can. Alternatively, the electronic clock 100 stores information (flag) to that effect in the ROM 332 or RAM 333 when the time zone is manually set, and whether or not the information (flag) is stored in the ROM 332 or RAM 333. The determination in step S504 may be made based on the above. Step S504 is executed, for example, by the calculation unit 331 shown in FIG.

In step S504, when the set time zone is not manually set (step S504: No), the set time zone is automatically set based on the current position of the electronic clock 100. Yes, it can be determined that the user did not set it independently. In this case, the electronic clock 100 determines whether or not the time zone determined in step S503 can be instructed by the pointer (step S505). This pointer is, for example, at least one of the hour hand 121, the minute hand 122, and the second hand 123 shown in FIG. 1, and an example is the second hand 123. The time zone that cannot be specified by the guideline is, for example, a time zone newly added by updating the map data. Step S505 is executed, for example, by the calculation unit 331 shown in FIG.

When the determined time zone can be indicated by the pointer in step S505 (step S505: Yes), the electronic clock 100 shifts to step S507. When the determined time zone cannot be instructed by the pointer (step S505: No), the electronic clock 100 performs the rounding process of the determined time zone (step S506). The time zone rounding process is a process of rounding the time zone into a time zone that can be instructed by a guideline. Step S506 is executed, for example, by the calculation unit 331 shown in FIG.

Next, the electronic clock 100 sets a time zone of its own device, corrects the display time based on the set time zone (step S507), and ends a series of processes. In step S507, for example, when the electronic clock 100 proceeds to step S507 via step S506, the electronic clock 100 sets a time zone rounded by the rounding process of step S506. Further, the electronic clock 100 sets the time zone determined by step S503 when the process proceeds to step S507 without going through step S506. When the electronic clock 100 is a satellite radio clock, the display time is corrected based on the set time zone and the time information acquired at the time of receiving the positioning. Alternatively, when the electronic clock 100 acquires only the position information by other communication means instead of the satellite radio clock, the display time is corrected by adding the time zone information to the internal time. The time zone setting in step S504 is executed by, for example, the calculation unit 331 shown in FIG.

The correction of the display time in step S507 is executed, for example, by the arithmetic unit 331 shown in FIG. 3 controlling the motor drive circuit 335. Further, in step S507, the electronic clock 100 stores in the ROM 332 or RAM 333 information indicating that the time zone is set based on the current position of the electronic clock 100 in step S507 in order to make a determination in step S504 in the future. You may.

In step S504, when the set time zone is manually set (step S504: Yes), it can be determined that the set time zone is independently set by the user. In this case, the electronic clock 100 determines whether or not the reception of the satellite radio wave in step S501 is scheduled reception (step S508). The determination of step S508 can be performed, for example, by determining whether step S501 is executed periodically or whether step S501 is executed by an instruction (forced) from the user. Step S508 is executed, for example, by the calculation unit 331 shown in FIG.

In step S508, when it is not scheduled reception (step S508: No), it can be determined that the reception of the satellite radio wave is not automatic but forced reception performed by the user's own operation. can. In this case, the electronic clock 100 proceeds to step S505 to set the time zone based on the current position of the electronic clock 100.

In the case of scheduled reception in step S508 (step S508: Yes), it can be determined that the reception of the satellite radio wave is not performed by the user's own operation but automatically. In this case, the electronic clock 100 determines whether or not the time difference (absolute value) between the set time zone and the time zone determined in step S503 is equal to or greater than a predetermined value (step S509). This predetermined value can be any value, but as an example, it can be about 2 hours. Step S509 is executed, for example, by the calculation unit 331 shown in FIG.

In step S509, when the time difference is equal to or greater than a predetermined value (step S509: Yes), it is determined that there is a large difference between the manually set time zone and the time zone corresponding to the current position of the electronic timepiece 100. Can be done. The reason for such a situation is, for example, that the current position of the electronic clock 100 has changed drastically due to the movement across countries. In this case, the electronic clock 100 proceeds to step S505 to set the time zone based on the current position of the electronic clock 100. As a result, the time zone of the electronic clock 100 can be automatically corrected to the time zone corresponding to the current position of the electronic clock 100.

In step S509, when the time difference is not equal to or greater than a predetermined value (step S509: No), it can be determined that the difference between the manually set time zone and the time zone corresponding to the current position of the electronic timepiece 100 is small. can. In this case, the electronic clock 100 ends a series of processes. As a result, it is possible to maintain the manually set time zone without setting the time zone based on the current position of the electronic clock 100.

By each step shown in FIG. 5, the electronic clock 100 sets a time zone based on the map data and the current position of the electronic clock 100 when the set time zone is not the time zone selected by the user operation (manually). do. If the set time zone is a time zone based on user operation or the set time zone has a small change between the time zone based on user operation and the time zone based on the current position, the map data and the electronic clock 100 Do not set a time zone based on your current position. As a result, it is possible to prevent the time zone set by the user's independent operation from being automatically changed, and to improve usability.

Further, even if the set time zone is the time zone based on the user operation, the electronic clock 100 is instructed (forced reception) to set the map data and the time zone based on the current position of the electronic clock 100 by the user operation. In that case, a time zone based on the map data and the current position of the electronic clock 100 is set. As a result, even if the time zone is set by the user's independent operation, if the user's independent operation gives an instruction to receive the position information, the time zone based on the map data and the current position of the electronic clock 100 is set. Can be set to improve usability.

Further, in the electronic clock 100, the set time zone is a time zone based on the user operation, and the time zone is already set even if the user operation is not instructed to set the time zone based on the map data and the current position of the electronic clock 100. When the time difference between the time zone of the above and the time zone based on the map data and the current position of the electronic clock 100 is equal to or more than a predetermined value, the time zone based on the map data and the current position of the electronic clock 100 is set. As a result, for example, when the user moves across the area together with the electronic clock 100 and the time zone manually set by the user in the past and the time zone of the current position are significantly different, the time zone of the current position is set. Usability can be improved.

Further, a process of determining whether or not the time difference between the time zone set in step S509 and the time zone based on the map data and the current position of the electronic clock 100 is equal to or greater than a predetermined value has been described. Not limited to processing. For example, the electronic clock 100 determines whether or not the distance between the position of the electronic clock 100 when the set time zone is set and the current position of the electronic clock 100 in step S509 is equal to or greater than a predetermined value. You may. Then, the electronic clock 100 proceeds to step S505 when this distance is equal to or greater than a predetermined value, and ends a series of processes when this distance is not equal to or greater than a predetermined value.

Alternatively, the electronic clock 100 has the map data and the current position of the electronic clock 100 even if the time difference between the set time zone and the time zone based on the map data and the current position of the electronic clock 100 is equal to or more than a predetermined value. It is not necessary to set the time zone based on the position. For example, when the process proceeds to step S509, a series of processes may be terminated. Alternatively, when the process proceeds to step S509, the user is inquired whether to set the time zone based on the map data and the current position of the electronic clock 100, and this time zone is set or not set according to the instruction from the user. You may do it. Alternatively, it may be possible to set whether or not to perform the process of step S509 by the user's operation. It is set not to perform the process of step S509 by the operation of the user, and when the process proceeds to step S509, a series of processes is terminated.

As described above, according to the electronic clock 100 according to the first embodiment, the time zone based on the correspondence information between the position and the time zone and the position of the own device is set, or the time zone based on the user operation is set. Then, the number of time zones that can be selected by the user operation is larger than the number of time zones that can be set based on the correspondence information between the position and the time zone and the position of the own device. As a result, the user can manually set a time zone that is not automatically set based on the position of the electronic clock 100, and a flexible time zone can be set.

Further, the electronic clock 100 not only indicates a time zone that can be set based on the corresponding information and the position of the own device, but also a time zone that is different from those time zones (a time zone that can be set only by user operation). A unit (time zone display unit 150) is provided. As a result, the user can recognize that there is a time zone that can be set only by the user operation, in addition to the time zone that is automatically set based on the correspondence information and the position of the own device.

For example, in the example shown in FIG. 2, each time zone indicated by the time zone display unit 150a can be set automatically and manually, and each time zone indicated by the time zone display units 150b and 150c can be set only manually. Although a certain configuration has been described, it is not limited to such a configuration. For example, each time zone indicated by the time zone display unit 150a can be set automatically and manually, each time zone indicated by the time zone display unit 150b can be set only manually, and each time indicated by the time zone display unit 150c. The zone may be configured so that it cannot be set automatically or manually.

In the example shown in FIG. 6, the electronic clock 100 is in the time zone setting mode with skip.

The time zone setting mode with skip is a mode in which the user can manually set the time zone of the electronic clock 100, and the user can select the time zone when the time zone of the setting candidate is sequentially switched according to the user's operation. This mode skips some time zones with low characteristics. Some time zones that are unlikely to be selected by the user are each time zone indicated by the time zone display unit 150c in the example shown in FIG.

In the time zone setting mode with skipping, for example, when the crown 131 is pulled one step and the crown 131 is rotated five times in the positive direction, the instruction directions by the second hand 123 are the instruction direction 601 and the instruction direction 602, the instruction direction 603, and the instruction direction 604.

The instruction direction 602 is the instruction direction by the second hand 123 at the stage where the crown 131 is pulled one step and the crown 131 is rotated once in the positive direction. In the example shown in FIG. 6, the instruction direction 602 is the direction of "+8" included in each time zone indicated by the time zone display unit 150a. That is, the second hand 123 skips the direction of "+7.5" included in each time zone indicated by the time zone display unit 150c, and the next "+8" direction included in each time zone indicated by the time zone display unit 150a. To instruct.

The instruction direction 603 is the instruction direction by the second hand 123 at the stage where the crown 131 is pulled one step and the crown 131 is rotated twice in the positive direction. In the example shown in FIG. 6, the instruction direction 603 is the direction of "+8.5" included in each time zone indicated by the time zone display unit 150a. That is, the second hand 123 skips the direction of "+8.25" included in each time zone indicated by the time zone display unit 150c, and the next "+8.5" included in each time zone indicated by the time zone display unit 150a. Indicate the direction of.

The instruction direction 604 is the instruction direction by the second hand 123 at the stage where the crown 131 is pulled one step and the crown 131 is rotated three times in the positive direction. In the example shown in FIG. 6, the instruction direction 604 is the direction of "+8.75" included in each time zone indicated by the time zone display unit 150a. That is, the second hand 123 indicates the direction of the next "+8.75" included in each time zone indicated by the time zone display unit 150a without skipping.

The instruction direction 605 is the instruction direction by the second hand 123 at the stage where the crown 131 is pulled one step and the crown 131 is rotated four times in the positive direction. In the example shown in FIG. 6, the instruction direction 605 is the direction of "+9" included in each time zone indicated by the time zone display unit 150a. That is, the second hand 123 indicates the direction of the next "+9" included in each time zone indicated by the time zone display unit 150a without skipping.

The instruction direction 606 is the instruction direction by the second hand 123 at the stage where the crown 131 is pulled one step and the crown 131 is rotated five times in the positive direction. In the example shown in FIG. 6, the instruction direction 606 is the direction of "+9.5" included in each time zone indicated by the time zone display unit 150a. That is, the second hand 123 skips the direction of "+9.25" included in each time zone indicated by the time zone display unit 150c, and the next "+9.5" included in each time zone indicated by the time zone display unit 150a. Indicate the direction of.

As shown in FIG. 6, in the time zone setting mode with skipping, the second hand 123 skips each time zone indicated by the time zone display unit 150c according to the rotation of the crown 131, while the time zone display unit 150a Indicate each time zone shown in sequence. Further, in the time zone setting mode with skipping, the second hand 123 skips each time zone (“−4.5” and “+10.5”) indicated by the time zone display unit 150b according to the rotation of the crown 131. Instruct without.

Further, the small window 160 according to the second embodiment may display the type of the time zone indicated by the second hand 123 in the time zone setting mode with skip. For example, "M / A", "M", and "Non" are written on the outer circumference of the left half of the small window 160 (near the character "SKIP"). "M / A" indicates that the time zone can be selected automatically or manually. "M" indicates that the time zone can be selected only manually. "Non" indicates that the time zone cannot be selected.

For example, when the second hand 123 indicates the instruction direction 601 to 606, the pointer 161 of the small window 160 indicates "M / A". Further, when the second hand 123 indicates the time zone display unit 150b (“−4.5” or “+10.5”), the pointer 161 of the small window 160 indicates “M”. As a result, the user can recognize the type of time zone indicated by the moved second hand 123 each time the crown 131 is pulled one step and the crown 131 is rotated.

Further, when the crown 131 is pushed in the time zone setting mode with skip, the electronic timepiece 100 sets the time zone instructed by the second hand 123 as the time zone of its own device. In FIG. 6, an example in which the crown 131 is rotated in the forward direction has been described, but when the crown 131 is rotated in the reverse direction, the second hand 123 is moved in the opposite direction to the example shown in FIG. May be good.

In the example shown in FIG. 6, the configuration in which the time zone to be skipped is each time zone indicated by the time zone display unit 150c has been described, but the configuration is not limited to such a configuration. For example, the time zone to be skipped may be each time zone indicated by the time zone display units 150a and 150c. In this case, only each time zone (“−4.5” or “+10.5”) indicated by the time zone display unit 150b is indicated according to the rotation of the crown 131.
As a result, when the user wants to set a time zone (“-4.5” or “+10.5”) that can be set only manually, the user can shift the electronic clock 100 to the time zone setting mode with skip. The time zone can be set by a simple operation.

(Operation of the time zone setting mode without skipping the electronic clock according to the second embodiment)
FIG. 7 is a diagram showing an example of the operation of the time zone setting mode without skipping of the electronic timepiece according to the second embodiment. In FIG. 7, the same parts as those shown in FIG. 6 are designated by the same reference numerals and the description thereof will be omitted. In the example shown in FIG. 7, the electronic clock 100 is in a time zone setting mode (all selection mode) without skipping.

The time zone setting mode without skipping is a mode in which the user can manually set the time zone of the electronic clock 100, and when the time zone of the setting candidate is sequentially switched according to the user's operation, about any time zone. It is a mode that does not skip.

In the time zone setting mode without skipping, for example, when the crown 131 is pulled one step and the crown 131 is rotated five times in the positive direction, the indicated directions by the second hand 123 are the indicated direction 701, the indicated direction 702, the indicated direction 703, and the indicated direction 704. It changes in the order of the indicated direction 705 and the indicated direction 706.

The instruction direction 701 is an instruction direction by the second hand 123 at the stage where the crown 131 is pulled one step, and is a direction indicating a time zone set in the electronic timepiece 100. In the example shown in FIG. 7, the instruction direction 701 is the direction of “+7” included in each time zone indicated by the time zone display unit 150a.

The instruction direction 702 is the instruction direction by the second hand 123 at the stage where the crown 131 is pulled one step and the crown 131 is rotated once in the positive direction. In the example shown in FIG. 7, the instruction direction 702 is the direction of "+7.5" included in each time zone indicated by the time zone display unit 150c. That is, the second hand 123 indicates the direction of "+7.5" included in each time zone indicated by the time zone display unit 150c without skipping.

The instruction direction 703 is the instruction direction by the second hand 123 at the stage where the crown 131 is pulled one step and the crown 131 is rotated twice in the positive direction. In the example shown in FIG. 7, the instruction direction 703 is the direction of “+8” included in each time zone indicated by the time zone display unit 150a. That is, the second hand 123 indicates the direction of the next "+8" included in each time zone indicated by the time zone display unit 150a.

The instruction direction 704 is the instruction direction by the second hand 123 at the stage where the crown 131 is pulled one step and the crown 131 is rotated three times in the positive direction. In the example shown in FIG. 7, the instruction direction 704 is the direction of "+8.25" included in each time zone indicated by the time zone display unit 150c. That is, the second hand 123 indicates the direction of the next "+8.25" included in each time zone indicated by the time zone display unit 150c without skipping.

The instruction direction 705 is the instruction direction by the second hand 123 at the stage where the crown 131 is pulled one step and the crown 131 is rotated four times in the positive direction. In the example shown in FIG. 7, the instruction direction 705 is the direction of "+8.5" included in each time zone indicated by the time zone display unit 150a. That is, the second hand 123 indicates the direction of the next "+8.5" included in each time zone indicated by the time zone display unit 150a.

The instruction direction 706 is the instruction direction by the second hand 123 at the stage where the crown 131 is pulled one step and the crown 131 is rotated five times in the positive direction. In the example shown in FIG. 7, the instruction direction 706 is the direction of “+8.75” included in each time zone indicated by the time zone display unit 150a. That is, the second hand 123 indicates the direction of the next "+8.75" included in each time zone indicated by the time zone display unit 150a.

As shown in FIG. 7, in the time zone setting mode without skipping, the second hand 123 sequentially shifts each time zone according to the rotation of the crown 131 without skipping the skipped time zone in the example shown in FIG. Instruct.

Further, the small window 160 according to the second embodiment may display the type of the time zone indicated by the second hand 123 in the time zone setting mode without skipping. For example, when the second hand 123 indicates the direction directions 701, 703, 705, and 706, the pointer 161 of the small window 160 indicates "M / A". Further, when the second hand 123 indicates the instruction directions 702 and 704, the pointer 161 of the small window 160 indicates "M". Each time the crown 131 is pulled one step and the crown 131 is rotated, the user can recognize the type of the time zone indicated by the moved second hand 123.

Further, when the crown 131 is pushed in the time zone setting mode without skipping, the electronic timepiece 100 sets the time zone instructed by the second hand 123 as the time zone of its own device. In FIG. 7, an example in which the crown 131 is rotated in the forward direction has been described, but when the crown 131 is rotated in the reverse direction, the second hand 123 is moved in the opposite direction to the example shown in FIG. May be good.

(Operation of the skip setting correction mode of the electronic clock according to the second embodiment)
FIG. 8 is a diagram showing an example of the operation of the skip setting correction mode of the electronic timepiece according to the second embodiment. In FIG. 8, the same parts as those shown in FIG. 7 are designated by the same reference numerals and the description thereof will be omitted. In the example shown in FIG. 8, the electronic clock 100 is in the skip setting correction mode. The skip setting correction mode is a mode in which the time zone to be skipped can be corrected in the time zone setting mode with skip described above.

In the skip setting correction mode, for example, when the crown 131 is pulled one step and the crown 131 is rotated five times in the positive direction, the instruction direction by the second hand 123 becomes the instruction direction 801 and the instruction direction 802, the instruction direction 803, the instruction direction 804, and the instruction direction 805. , The direction changes in the order of the indicated direction 806. The change of the second hand 123 is the same as the change of the second hand 123 in the time zone setting mode without skip shown in FIG. 7. That is, the second hand 123 sequentially indicates each time zone according to the rotation of the crown 131 without skipping.

Further, when the PB operation (for example, pressing at least one of the first push button 132 and the second push button 133) is performed in the skip setting correction mode, the electronic clock 100 has a time zone indicated by the second hand 123 at that time. Switches whether or not it is a skip target in the time zone setting mode with skip. Further, when the crown 131 is pushed in the skip setting correction mode, the electronic watch 100 ends the skip setting correction mode.

Further, the small window 160 according to the second embodiment may display whether or not the time zone indicated by the second hand 123 is set as the skip target in the skip setting correction mode. For example, "ON" and "OFF" are written on the outer circumference of the right half of the small window 160. “ON” indicates that the time zone is the time zone to be skipped in the time zone setting mode with skipping. "OFF" indicates that the time zone is not the time zone to be skipped in the time zone setting mode with skipping.

Here, as an initial state, as in the examples shown in FIGS. 6 and 7, each time zone indicated by the time zone display units 150a and 150b is a skip target in the time zone setting mode with skip, and the time zone display unit It is assumed that each time zone indicated by 150c is not a skip target in the time zone setting mode with skip.

For example, when the second hand 123 is instructing the instruction directions 801, 803, 805, 806, the pointer 161 of the small window 160 is instructing "OFF". Further, when the second hand 123 indicates the instruction directions 802 and 804, the pointer 161 of the small window 160 indicates "ON". Further, when the second hand 123 indicates the time zone display unit 150b (“−4.5” or “+10.5”), the pointer 161 of the small window 160 indicates “OFF”. As a result, each time the user pulls the crown 131 one step and rotates the crown 131, the user recognizes whether or not the time zone indicated by the moved second hand 123 is currently the skip target in the time zone setting mode with skip. can.

Further, for example, when the second hand 123 indicates the instruction direction 803, the pointer 161 of the small window 160 indicates "OFF" as described above. When the user performs a PB operation in this state, the instruction destination of the pointer 161 is switched from "OFF" to "ON", and the time zone ("+8") corresponding to the instruction direction 803 is skipped in the time zone setting mode with skip. Become a target.

Further, for example, when the second hand 123 indicates the instruction direction 804, the pointer 161 of the small window 160 indicates "ON" as described above. When the user performs a PB operation in this state, the instruction destination of the pointer 161 is switched from "ON" to "OFF", and the time zone ("+8.25") corresponding to the instruction direction 804 is a time zone setting mode with skip. It is no longer the target of skipping in.

(Setting processing by the electronic clock according to the second embodiment)
9 to 11 are flowcharts showing an example of the setting process by the electronic clock according to the second embodiment. The electronic timepiece 100 according to the second embodiment executes each step shown in FIGS. 9 to 11 when the crown 131 is pulled (crown pull) in the time display mode (normal mode) for displaying the time, for example. Each step shown in FIGS. 9 to 11 is executed by, for example, the calculation unit 331 shown in FIG.

As shown in FIG. 9, first, the electronic clock 100 reads the set time zone from the ROM 332 or the RAM 333 (step S901). Next, the electronic clock 100 moves the designated position of the time zone by the second hand 123 based on the time zone read out in step S901 (step S902). For example, the electronic clock 100 moves the designated position of the time zone by the second hand 123 so as to indicate the time zone read by step S901.

Next, the electronic clock 100 determines whether or not the PB operation (push button operation) is continued (step S903). The PB operation is, for example, an operation of pressing at least one of the first push button 132 and the second push button 133. When the PB operation is not continued (step S903: No), the electronic clock 100 transitions to the time zone setting mode with skip (step S904). That is, the user can shift the electronic watch 100 to the time zone setting mode with skip by pulling the crown 131 without performing the PB operation.

In the time zone setting mode with skip, the electronic clock 100 determines whether or not the PB operation is continued for a predetermined time or more (step S905). The predetermined time can be any time, but as an example, it can be 4 seconds. When the PB operation is not continued for a predetermined time or more (step S905: No), the electronic timepiece 100 determines whether or not there is a forward rotation input of the crown 131 (step S906). When there is a forward rotation input (step S906: Yes), the electronic clock 100 moves the time zone indicated by the second hand 123 by +1 (step S907). To move by +1 means, for example, to move only the smallest unit in the positive order. The minimum unit is, for example, each interval of each time zone shown by the 60 time zone display units 150 shown in FIG.

Next, the electronic clock 100 determines whether or not the time zone indicated by the second hand 123 is the time zone to be skipped (step S908). When the time zone designated by the second hand 123 is the time zone to be skipped (step S908: Yes), the electronic clock 100 returns to step S907 to further move the designated time zone. If the time zone designated by the second hand 123 is not the time zone to be skipped (step S908: No), the electronic clock 100 returns to step S905.

In step S906, when there is no forward rotation input (step S906: No), the electronic watch 100 determines whether or not there is a reverse rotation input of the crown 131 (step S909). When there is a reverse rotation input (step S909: Yes), the electronic clock 100 moves the time zone indicated by the second hand 123 by -1 (step S910). To move only -1 means, for example, to move only the smallest unit in the reverse order.

Next, the electronic clock 100 determines whether or not the time zone indicated by the second hand 123 is the time zone to be skipped (step S911). When the time zone designated by the second hand 123 is the time zone to be skipped (step S9111: Yes), the electronic clock 100 returns to step S910 to further move the designated time zone. If the time zone designated by the second hand 123 is not the time zone to be skipped (step S9111: No), the electronic clock 100 returns to step S905.

In step S909, when there is no reverse rotation input (step S909: No), the electronic watch 100 determines whether or not the crown 131 has been pushed in (step S912). When the crown 131 is not pushed in (step S912: No), the electronic watch 100 returns to step S905.

When the crown 131 is pushed in in step S912 (step S912: Yes), the electronic watch 100 updates the time zone setting of its own device to the time zone indicated by the second hand 123 (step S912). S913), the series of processes is completed, and the process returns to the time display mode. After step S913, the electronic clock 100 displays the time based on the updated time zone.

In step S905, when the PB operation is continued for a predetermined time or longer (step S905: Yes), the electronic clock 100 shifts to step S914 shown in FIG. 10 (A), and shifts to the time zone setting mode without skipping. (Step S914). That is, the user can shift the electronic clock 100 to the time zone setting mode without skip by performing the PB operation for a predetermined time or longer after shifting the electronic clock 100 to the time zone setting mode with skip.

In the time zone setting mode without skipping, the electronic timepiece 100 determines whether or not there is a forward rotation input of the crown 131 (step S915). When there is a forward rotation input (step S915: Yes), the electronic clock 100 moves the time zone indicated by the second hand 123 by +1 (step S916), and returns to step S915.

When there is no forward rotation input in step S915 (step S915: No), the electronic watch 100 determines whether or not there is a reverse rotation input of the crown 131 (step S917). When there is a reverse rotation input (step S917: Yes), the electronic clock 100 moves the time zone indicated by the second hand 123 by -1 (step S918), and returns to step S915.

In step S917, when there is no reverse rotation input (step S917: No), the electronic watch 100 determines whether or not the crown 131 has been pushed in (step S919). When the crown 131 is not pushed in (step S919: No), the electronic watch 100 returns to step S915. When the crown 131 is pushed in (step S919: Yes), the electronic watch 100 shifts to step S913 shown in FIG. 9 (B).

When the PB operation is continued in step S903 shown in FIG. 9 (step S903: Yes), the electronic clock 100 shifts to step S920 shown in FIG. 11 (C) and shifts to the skip setting correction mode (step S903: Yes). Step S920). That is, the user can shift the electronic watch 100 to the skip setting correction mode by pulling the crown 131 while performing the PB operation.

In the skip setting correction mode, the electronic clock 100 shifts to step S921. Steps S921 to S924 are the same as steps S915 to S918. In step S923, when there is no reverse rotation input (step S923: No), the electronic clock 100 determines whether or not there is a PB operation (step S925).

If there is no PB operation in step S925 (step S925: No), the electronic clock 100 shifts to step S927. When there is a PB operation (step S925: Yes), the electronic clock 100 changes the skip setting for the time zone indicated by the second hand 123 at that time (step S926). For example, when the time zone is the skip target in the time zone setting mode with skip, the electronic clock 100 excludes the time zone from the skip target in the time zone setting mode with skip. If the time zone is not the skip target in the time zone setting mode with skip, the electronic clock 100 adds the time zone to the skip target in the time zone setting mode with skip.

Next, the electronic watch 100 determines whether or not the crown 131 has been pushed in (step S927). When the crown 131 is not pushed in (step S927: No), the electronic watch 100 returns to step S921. When the crown 131 is pushed in (step S927: Yes), the electronic watch 100 ends a series of processes without updating the time zone setting and returns to the time display mode (D).

(Mode transition of the electronic clock according to the second embodiment)
FIG. 12 is a diagram showing an example of the mode transition of the electronic timepiece according to the second embodiment. The electronic clock 100 according to the second embodiment transitions to each mode shown in FIG. 12, for example. First, the electronic clock 100 transitions to the time display mode 1201 as the steady mode. In the time display mode 1201, the electronic clock 100 displays the time based on the set time zone by the time display unit 351.

When the crown is pulled by one step in the time display mode 1201 (one step of the crown is pulled), the electronic watch 100 transitions to the time zone setting mode 1202 with skipping. When the crown 131 rotates in the forward direction in the time zone setting mode 1202 with skipping, the electronic watch 100 changes the time zone instructed by the second hand 123 to the next selectable time zone in the normal order (normal time zone). Further, when the crown 131 rotates in the reverse direction in the time zone setting mode 1202 with skipping, the electronic watch 100 changes the time zone instructed by the second hand 123 to the next selectable time zone in the reverse order (time zone reverse order).

Further, when the crown 131 is pushed in the time zone setting mode 1202 with skipping (crown 0 step pull), the electronic watch 100 returns to the time display mode 1201. At this time, the electronic clock 100 updates the time zone setting of its own device so that it becomes the time zone indicated by the second hand 123. Further, when the PB operation continues for a predetermined time (for example, 4 seconds) or more in the time zone setting mode 1202 with skip, the electronic clock 100 transitions to the time zone setting mode 1203 without skip.

When the crown 131 rotates forward in the time zone setting mode 1203 without skipping, the electronic watch 100 moves the time zone indicated by the second hand 123 by +1 (time zone +1). Further, when the crown 131 rotates in the reverse direction in the time zone setting mode 1203 without skipping, the electronic timepiece 100 moves the time zone designated by the second hand 123 by -1 (time zone -1). Further, when the crown 131 is pushed in the time zone setting mode 1203 without skipping (crown 0 step pull), the electronic watch 100 returns to the time display mode 1201. At this time, the electronic clock 100 updates the time zone setting of its own device so that it becomes the time zone indicated by the second hand 123.

When the crown 131 is pulled by one step while operating the PB in the time display mode 1201 (the crown is pulled by one step), the electronic watch 100 transitions to the skip setting correction mode 1204. When the crown 131 rotates forward in the skip setting correction mode 1204, the electronic timepiece 100 moves the time zone indicated by the second hand 123 by +1 (time zone +1). Further, when the crown 131 rotates in the reverse direction in the skip setting correction mode 1204, the electronic timepiece 100 moves the time zone indicated by the second hand 123 by -1 (time zone -1).

Further, when the PB operation is performed in the skip setting correction mode 1204, the electronic clock 100 changes ON / OFF of the skip of the time zone indicated by the second hand 123 at that time. For example, when the time zone indicated by the second hand 123 is the skip target in the time zone setting mode 1202, the electronic clock 100 excludes the time zone from the skip target in the time zone setting mode 1202. If the time zone indicated by the second hand 123 is not the skip target in the time zone setting mode 1202, the electronic clock 100 adds the time zone to the skip target in the time zone setting mode 1202. Further, when the crown 131 is pushed in the skip setting correction mode 1204 (crown 0 step pull), the electronic watch 100 returns to the time display mode 1201.

As described above, according to the electronic watch 100 according to the second embodiment, when the time zone based on the user operation is set, the time zone is set according to the first operation by the user (for example, the crown 131 is rotated in a state of being pulled by one step). Selection candidates are selected according to the first state (time zone setting mode without skipping) in which each time zone of the selection candidates is sequentially notified to the user, and the second operation by the user (for example, rotation with the crown 131 pulled one step). It is possible to switch between a second state (for example, a time zone setting mode with skipping) in which the user is sequentially notified of the time zones excluding some of the time zones in each time zone. Then, the time zone notified when the third operation (pushing of the crown 131) by the user is received in the first state or the second state is set.

As a result, the user can select a time zone from each time zone of the selection candidates by setting the electronic clock 100 in the first state, and the user can select the time zone by setting the electronic clock 100 in the second state. Notification of time zones that are unlikely to be done can be skipped, facilitating the selection of time zones that are likely to be selected by the user. Therefore, it is possible to improve usability when setting the time zone based on the user operation.

Further, as an example, the time zone in which the notification is skipped in the second state is based on the map data and the current position of the electronic clock 100 in each time zone of the selection candidates as shown in the example shown in FIG. It can be a time zone that is not included in the time zone that can be set (a time zone that can be set only manually). However, the time zone in which the notification is skipped in the second state is not limited to this.

For example, the time zone in which the notification is skipped in the second state may be a time zone set based on the map data and the current position of the electronic clock 100. That is, when the user manually selects the time zone, the user is likely to want to select the time zone that can be selected only by the user operation, so that the time zone is set based on the map data and the current position of the electronic clock 100. It can be said that the time zone is a time zone that is unlikely to be selected.

Alternatively, the time zone in which the notification is skipped in the second state may be the currently set time zone. That is, if the user manually selects a time zone, the currently set time zone may be selected because the user is likely to want to select a different time zone than the currently set time zone. It can be said that it is a low time zone.

Further, the electronic clock 100 may be capable of transitioning to a state in which the time zone in which the notification is skipped in the second state can be changed based on an operation by the user (for example, a skip setting correction mode). As a result, the user sets the time zone to be notified to the user in the second state in advance by setting the time zone in which the notification is skipped in the second state for the time zone that is unlikely to be selected by the user. It can be a time zone that is likely to be selected by, and usability can be improved.

Further, whether or not the electronic clock 100 can be set based on the map data and the current position of the electronic clock 100 for each of the time zones that can be selected by the user operation (for example, "M / A" or "M"). May be notified to the user. Thereby, the user can recognize whether each time zone is a time zone that can be set by both user operation and automatic operation, or a time zone that can be set only by user operation.

In the time zone setting mode with skip and the time zone setting mode without skip, the configuration in which the type of each time zone is displayed by the small window 160 has been described, but the configuration is not limited to such a configuration. For example, a mode for displaying the type of each time zone may be provided without setting the time zone.

Further, the configuration for switching between the time zone setting mode with skip and the time zone setting mode without skip by the combination of crown 131 and PB operation has been described, but the configuration is not limited to such a configuration. For example, with the crown 131 pulled out one step, if the crown 131 is rotated forward (first operation), the time zone indicated by the second hand 123 is switched without skipping, and if the crown 131 is rotated in the reverse direction (second operation), it is skipped. With or without, the time zone indicated by the second hand 123 may be switched.

Further, the electronic clock 100 may be capable of transitioning to a skip setting confirmation mode different from the time zone setting mode with skip, the time zone setting mode without skip, and the skip setting correction mode. In the skip setting confirmation mode, the electronic clock 100 moves the second hand 123 without skipping according to the user operation, and the time zone indicated by the second hand 123 can be automatically or manually selected (“M / A”). , It may be notified by the guideline 161 whether it can be selected only manually (“M”) or “Non” which cannot be selected.

Further, the skip setting described above may be performed on the application or software of the external device by the electronic watch 100 communicating with the external device such as a smartphone or a PC (Personal Computer).

Further, the past positioning information by the electronic clock 100 is stored as a log in ROM 332 or the like, and only the time zone with the log (city where the user has visited) (or the time zone with the log and the time zone with only manual setting). May be set to be selectable and other time zones may be skipped. In this case, the log data of the positioning information may be output to an external device or the like. Further, in this case, the skip setting based on the positioning information log may be set on the application or software of the external device. As a result, it is possible to save the storage area of the ROM 332 of the electronic clock 100 and the like, and to avoid the loss of the positioning information log even if the data of the electronic clock 100 is lost due to a voltage drop or the like.

(Embodiment 3)
A part different from the first and second embodiments will be described with respect to the third embodiment.

(Electronic clock according to the third embodiment)
FIG. 13 is a diagram showing an example of an electronic clock according to the third embodiment. In FIG. 13, the same parts as those shown in FIG. 2 are designated by the same reference numerals and the description thereof will be omitted. As shown in FIG. 13, the time zone display unit 150c may be omitted from the time zone display units 150a, 150b, and 150c shown in FIG.

For example, "-4.5" and "+10.5" shown by the time zone display unit 150b shown in FIG. 13 were adopted in some areas when the electronic clock 100 was designed, but now there are areas where they are adopted. However, it is assumed that the current map data is not associated with any position.

In this case, for example, each time zone indicated by the time zone display unit 150a may be set automatically and manually, and each time zone indicated by the time zone display unit 150b may be set only manually. As a result, the user who wants to display the time based on "-4.5" or "+10.5" on the electronic clock 100 can manually set "-4.5" or "+10.5". Become.

Further, for example, when designing the electronic clock 100, there is no area where "+8.5" is adopted, and the electronic clock 100 shown in FIG. 13 has a time zone display unit 150d (dotted line) indicating "+8.5". I will not. Then, it is assumed that there is an area that adopts "+8.5" at present, and that the area is associated with "+8.5" in the current map data. In this case, for example, in the process shown in FIG. 5, "+8.5" is specified by step S503. Further, it is determined by step S505 that "+8.5" cannot be instructed by the guideline. Further, "+8.5" is rounded to "+8" or "+9" by step S506. Further, "+8" or "+9" is set by step S507.

As described above, also in the electronic clock 100 according to the third embodiment, the number of time zones (each time zone indicated by the time zone display units 150a and 150b) that can be selected by the user operation is the correspondence information between the position and the time zone. The number is larger than the number of time zones (each time zone indicated by the time zone display unit 150a) that can be set based on the position of the own device. As a result, the user can manually set a time zone (each time zone indicated by the time zone display unit 150b) that is not automatically set based on the position of the electronic clock 100, and can set a flexible time zone. Will be possible.

(Embodiment 4)
The parts of the fourth embodiment different from those of the first to third embodiments will be described.

(Electronic clock according to the fourth embodiment)
FIG. 14 is a diagram showing a part of an example of the electronic clock according to the fourth embodiment. In FIG. 14, the same components as those in FIG. 1 are designated by the same reference numerals and description thereof will be omitted. As shown in FIG. 14, on the outer periphery of the time zone display unit 150 of the electronic timepiece 100 according to the fourth embodiment, instead of the time difference information such as "+1", "+2", "+3", or together with the time difference information. , The city name corresponding to the time zone may be written. In the example shown in FIG. 14, city names such as BJS (Beijing), TYO (Tokyo), ADL (Adelaide), and SYD (Sydney) are written on the outer periphery of the time zone display unit 150 together with the time difference information. As a result, the user can set and confirm the time zone by the city name.

Further, as in the example shown in FIG. 14, different city names may be selected in the same time zone. For example, the time zone with a time difference of "+10" includes not only Sydney (SYD) but also Guam (GUM) and Vladivostok (VLD). For this reason, the time zone of a typical city name (for example, Sydney) is automatically selected by reception, and the same time zone such as Guam or Vladivostok may be selected by manual setting. .. This improves usability because it is possible to select a city name that is closer to the observation point even in the same time zone.

Further, in this case, as in the example shown in FIG. 14, city names in the same time zone may be arranged adjacent to each other, and indicators 1401 to 1404 indicating that they are in the same time zone may be provided. For example, indicator 1403 indicates that Sydney (SYD), Guam (GUM) and Vladivostok (VLD) are in the same time zone with a time difference of "+10".

Further, since a city closer to the observation point (user) can be selected even in the same time zone in this way, the distance to that city may be indicated by the guideline 161 or the like. Further, when the directional sensor is mounted on the electronic clock 100, the direction of the city may be indicated by the pointer 161 or the like.

In the example shown in FIG. 14, the city name is written on the bezel of the electronic timepiece 100, but the configuration is not limited to this. For example, the city name may be written on the dial ring of the electronic clock 100.

As described above, according to the electronic clock 100 according to the fourth embodiment, usability can be improved by noting the city name corresponding to the time zone on the bezel or the like.

(Embodiment 5)
The parts of the fifth embodiment different from those of the first to fourth embodiments will be described.

(Electronic clock according to the fifth embodiment)
15 and 16 are diagrams showing a part of an example of the electronic clock according to the fifth embodiment. In FIGS. 15 and 16, the same components as those in FIG. 2 are designated by the same reference numerals, and the description thereof will be omitted. As shown in FIGS. 15 and 16, a display device 1510 capable of rewriting the display contents such as a liquid crystal display or electronic paper may be used for the bezel or the dial ring of the electronic clock 100 for displaying the city name or the like. As an example, E-ink electronic paper can be used as the electronic paper. E-ink is a registered trademark.

For example, the display device 1510 rewrites the city name to be displayed together with the time difference of the time zone according to the setting by the user or the like. As an example, as in the example shown in FIG. 15, Sydney (SYD) is displayed corresponding to the time zone of the time difference “+10”, but as in the example shown in FIG. 16, depending on the setting by the user. Guam (GUM) may be displayed corresponding to the time zone of the time difference "+10".

Further, the rewriting of the display contents by the display device 1510 can be applied to the case where a plurality of city names are displayed corresponding to the same time zone as shown in FIG. Further, whether one city name can be displayed for each time zone as in the examples shown in FIGS. 15 and 16 or a plurality of city names can be displayed for each time zone as shown in FIG. 14 can be displayed. It may be switchable according to the user setting.

17 and 18 are diagrams showing a part of another example of the electronic clock according to the fifth embodiment. In FIGS. 17 and 18, the same components as those in FIGS. 15 and 16 are designated by the same reference numerals, and the description thereof will be omitted. The electronic clock 100 according to the fifth embodiment may display the time difference of each time zone on the display device 1510, and may switch the display interval of the time difference of each time zone according to the map data of the ROM 332. As an example, the electronic clock 100 may switch the display content of the display device 1510 from the display content shown in FIG. 17 to the display content shown in FIG.

As described above, according to the electronic clock 100 according to the fifth embodiment, by having the rewritable display device 1510, it becomes possible to flexibly select a city that can be automatically or manually selected.

In each of the above-described embodiments, the configuration for specifying the current position of the electronic clock 100 based on the satellite radio wave has been described, but the configuration is not limited to such a configuration. For example, the electronic clock 100 may specify the current position of the electronic clock 100 based on a wireless signal from a wireless LAN or a base station for cellular communication.

Further, although the configuration for specifying the current time (standard time) based on the satellite radio wave has been described, the configuration is not limited to such a configuration. For example, the electronic clock 100 may specify the current time (standard time) based on a standard radio wave transmitted from a transmission station on the ground. Alternatively, the electronic clock 100 may specify the current time (standard time) based on the time information received from other communication devices (various base stations and wireless terminals).

Further, although the configuration in which the electronic clock 100 is a wristwatch has been described, the configuration is not limited to such a configuration. For example, the electronic clock 100 may be a clock such as a pocket watch, a table clock, or a wall clock. Further, although the configuration in which the electronic clock 100 is an analog clock that displays the time by a pointer has been described, the configuration is not limited to such a configuration. For example, the electronic clock 100 may be a digital clock that displays the time on a display, an audio clock that notifies the time by voice, or the like.

As described above, according to the electronic clock, it is possible to flexibly set the time zone.

For example, conventionally, a watch has been known in which the currently specified time is corrected to the time corresponding to the set time zone by specifying the time zone (time difference or city name) by operating the crown or push button. ing. A time zone is an entire region that uses a common standard time, and may be referred to as, for example, a standard time zone, a time zone, or an isochronous zone. The time zone is indicated by, for example, the difference between the standard time of the region and UTC (Coordinated Universal Time). As an example, Japan is included in the time zone where the difference between standard time and UTC is +9. Therefore, the time zone including Japan is represented as, for example, "UTC + 9" or "+9".

Further, in a clock capable of acquiring satellite radio waves such as GPS, the current location can be measured (positioning) by receiving signals from a plurality of satellites (usually four satellites). Therefore, by storing the time zone information in association with the map data, it is possible to determine the time zone of the current location from the positioning information and the map data.

Which time zone each country is included in may change depending on the political and economic reasons of each country. When the correspondence between each country and each time zone changes and the map data including the time zone of the clock is updated, the specified time zone may not be used or a new time zone may be added. Is assumed.

For example, it is conceivable to update the map data of the clock of the model released in the past to the current map data. For example, if there is a time zone that is no longer used due to the update of map data, some users may want to use that time zone. On the other hand, according to each of the above-described embodiments, the number of time zones that can be manually specified after updating the map data is larger than the number of time zones that can be specified by automatic reception. Therefore, it is possible to manually specify a time zone that cannot be specified by automatic reception, such as a time zone deleted from the map data, so that usability can be improved.

As described above, the electronic clock according to the present invention is useful for various electronic clocks that notify the time based on the time zone, and is particularly suitable for satellite radio-controlled wristwatches.
