FIG. 2 is a block diagram showing a functional configuration of the analog electronic timepiece 1.
The analog electronic timepiece 1 includes a CPU 41 (Central Processing Unit) (update information acquisition means, local time setting means, local time calculation means), a ROM 42 (Read Only Memory), and a RAM 43 (Random Access Memory) (update information storage means). An oscillation circuit 44, a frequency dividing circuit 45, a timing circuit 46 as a timing unit, an operation unit 47 as an operation unit, and a satellite radio wave reception processing unit 48 (current position acquisition unit, reception unit, position calculation unit) The antenna 49, the drive circuit 51, the power source 52, the time pointers 61 to 63, the 24-hour hand 64, the date indicator 65, the mode pointer 66, the small minute hand 67 and the small hour hand 68, and the gear train mechanism 71. To 75, stepping motors 81 to 85, and the like.

The CPU 41 performs various arithmetic processes and controls the overall operation of the analog electronic timepiece 1. The CPU 41 controls the pointer operation related to the date and time display. The CPU 41 converts the date and time counted by the clock circuit 46 based on the local time setting information (local time information) including the set time zone and daylight saving time implementation information, and in the normal time display mode. The converted local time is displayed by the time hands 61 to 63, the 24-hour hand 64, and the date indicator 65.
In addition, the CPU 41 operates the satellite radio wave reception processing unit 48 to acquire date / time and position information. The CPU 41 corrects the date and time counted by the timer circuit 46 based on the obtained date and time data.

  The ROM 42 stores various control programs 42a executed by the CPU 41 and setting data. The program 42a includes, for example, a program related to operation control in various function modes. The setting data includes city time difference information 42b and city daylight saving time information 42c.

  The city time difference information 42b includes the ID of the geographical position related to the city sign (abbreviation of city name) provided on the outer edge of the dial 3, the position (for example, the number of steps by the second hand 61 from the 12 o'clock direction), and the A time difference from the UTC time in the city (hereinafter, the time difference represents a time difference from the UTC time) is associated and stored as time zone setting information. For example, an ID “011”, a 22-second position, and a time difference of +9 hours are stored in association with a city sign “TYO” indicating Tokyo provided at a position near 4:20.

  The city daylight saving time information 42c includes the above-mentioned cities and daylight saving time implementation information in the city, that is, whether or not daylight saving time is implemented, the implementation period (start date and end date), and the shift from the standard time during the daylight saving time implementation period. Information related to time is stored in association with each other. For example, for a city sign “LON” indicating London at 2 seconds, ID “002”, position (2 seconds), daylight saving time implementation period (from 10:00 UTC on the last Sunday in March to the last Sunday in October) And the shift time (+1 hour) in the daylight saving time implementation period are stored in association with each other.

  The RAM 43 provides a working memory space to the CPU 41 and stores temporary data. The RAM 43 stores date / time information and position information acquisition history, local time setting information including the currently selected time zone and daylight saving time implementation information, data indicating the pointer position, and the like. Further, the RAM 43 stores city user correction data 43a and map user correction data 43b, which are correction data of time zone and daylight saving time implementation information set by the user.

  In the city user correction data 43a, the correction information is stored for the information in which the correction information of the time zone and daylight saving time implementation information in each city is set. For example, if daylight saving time implementation information is set by the user as described later when daylight saving time is implemented in Tokyo, an ID indicating Tokyo and the setting are stored in association with each other. The storage number of this setting may be only the latest one, or it may be possible to store all the cities for which the setting has been made. If there are multiple settings for the same city (ID), only the latest setting is stored. Further, the correction information may include a validity period of the correction information.

In the map user correction data 43b, as described later, when the correction information of the time zone and daylight saving time implementation information at the acquired current position (latitude and longitude) is set, the current position or the area including the current position (predetermined) ID) and the set correction information are stored in association with each other. When data indicating the current position is stored, the latitude / longitude of the acquired current position itself may be used, or the coordinates of each geographic block stored in the time difference map 48b may be used. Also in this case, the number of settings is appropriately set according to the storage capacity and the like, and when there are a plurality of settings within the same region, only the latest setting is stored. This correction information may also include the validity period of the correction information.
The city user correction data 43a and the map user correction data 43b constitute update information.

The oscillation circuit 44 generates and outputs a predetermined frequency signal. The oscillation circuit 44 includes, for example, a crystal oscillator.
The frequency dividing circuit 45 divides the frequency signal output from the oscillation circuit 44 into a frequency signal used by the CPU 41 or the time measuring circuit 46 and outputs the frequency signal. The output frequency may be set to be changeable by a control signal from the CPU 41.

  The timer circuit 46 counts the current date and time by counting and adding the frequency-divided signal input from the frequency divider circuit 45 to an initial value indicating a predetermined date and time. The date and time counted by the timer circuit 46 has an error (a rate) according to the accuracy of the oscillation circuit 44, for example, about 0.5 seconds per day. The date and time counted by the timer circuit 46 can be corrected by a control signal from the CPU 41.

  The operation unit 47 receives an input operation from the user. The operation unit 47 includes the push button switches B1 to B4 described above. When the push button switches B1 to B4 are respectively pressed, or the crown C1 is pulled out, pushed back, or rotated, an electric signal corresponding to the operation type is output to the CPU 41. The crown C1 can be pulled out in two stages, and accepts operations corresponding to the drawer state.

  The satellite radio wave reception processing unit 48 uses the antenna 49 to receive radio waves from positioning satellites including at least positioning satellites (GPS satellites) related to GPS (Global Positioning System), and the spectrum-spread transmission radio waves from these positioning satellites. The signal (navigation message data) is decoded and decoded. Various arithmetic processes are further performed as necessary on the content of the decoded navigation message data, and data according to a request from the CPU 41 is output to the CPU 41 in a preset format. Operation control relating to reception, decoding, calculation, and output is performed by a control unit 48a (microcomputer) provided in the satellite radio wave reception processing unit 48.

  Each component of the satellite radio wave reception processing unit 48 is collectively formed as one module on the chip and connected to the CPU 41. The operation of the satellite radio wave reception processing unit 48 is controlled to be turned on / off by the CPU 41 independently of the operations of the other units of the analog electronic timepiece 1. In the analog electronic timepiece 1, when it is not necessary to operate the satellite radio wave reception processing unit 48, power saving is achieved by interrupting the power supply to the satellite radio wave reception processing unit 48.

  The satellite radio wave reception processing unit 48 includes a storage unit. The storage unit uses a non-volatile memory such as a flash memory or an EEPROM (Electrically Erasable and Programmable Read Only Memory), and holds the stored contents regardless of the power supply state to the satellite radio wave reception processing unit 48. In the storage unit, in addition to various operation control programs, setting data such as predicted orbit information and leap second correction value of each positioning satellite acquired from the positioning satellite, a time difference map 48b for obtaining local time setting information, time difference information 48c and daylight saving time information 48d are stored. The local time setting information may be stored in the RAM 43 of the analog electronic timepiece 1, and the control unit 48a may receive information from the CPU 41 or cause the CPU 41 to perform necessary processing as necessary. good. Further, the operation control program may be stored in a dedicated ROM, read at startup, and loaded into the RAM of the control unit 48a.

  The time difference map 48b is map data that divides the world map into appropriate geographic blocks (geographic positions) and stores parameters related to time zones belonging to the respective geographic blocks and parameters related to daylight saving time. Although the map of the time difference map 48b is not particularly limited, a map in which the latitude line and the longitude line are each represented by a straight line and drawn orthogonally is preferably used, and each geographic block has a predetermined latitude interval and longitude. They are preferably arranged in a two-dimensional matrix at intervals. Further, the geographic block may be determined so that the actual size does not greatly differ between the geographic blocks by making the longitude widths different between the high latitude region and the low latitude region.

  The time difference information 48c is table data that associates the parameters related to the time zone used in the time difference map 48b with the time difference in the time zone. In this table data, the parameters are uniquely set such that, for example, the time difference corresponding to the parameter “0” is “+0 hours” and the time difference corresponding to the parameter “1” is “+1 hours”.

The daylight saving time information 48d is table data that associates the parameters related to daylight saving time used in the time difference map 48b with the contents of the daylight saving time implementation information (implementation presence / absence, implementation period, shift time at implementation). For example, the parameter “0” is associated with no daylight saving time, and the parameter “1” is set to +1 hour from 1 am on the last Sunday in March to 1 am on the last Sunday in October in UTC. It is set in association with the case implemented in
In this way, the same range of the parameter relating to the time zone and the parameter relating to daylight saving time is determined as one region (predetermined region). Alternatively, even if the contents of the daylight saving time implementation information are the same, parameters may be set separately for different time zones, and the daylight saving time parameters may be defined as one region within the same range. Further, the area may be determined by the contents of daylight saving time implementation information or administrative units smaller than the time zone.
The ROM 42 and the satellite radio wave reception processing unit 48 constitute local time information storage means. The city time difference information 42b, the city daylight saving time information 42c and the time difference map 48b of the ROM 42, and the time difference information 48c and the daylight saving time information 48d of the satellite radio wave reception processing unit 48 are provided. Constitutes local time information. Of these, the city time difference information 42b and the time difference information 48c have time zone setting information at each position, and the city daylight time information 42c and the daylight time information 48d have daylight saving time implementation information at each position.

  The power supply unit 52 supplies power related to the operation of each unit at a predetermined voltage. The power supply unit 52 includes a battery, and includes, for example, a solar panel and a secondary battery as the battery. Alternatively, a replaceable button type dry battery may be used as the battery. Further, when a plurality of different voltages are output from the power supply unit 52, for example, a configuration that can be converted into a desired voltage using a switching power supply or the like can be output.

The stepping motor 81 rotates the second hand 61 via a gear train mechanism 71 that is an array of a plurality of gears. When the stepping motor 81 is driven once, the second hand 61 rotates 6 degrees for one step, and makes a round on the dial 3 by the operation of the stepping motor 81 60 times.
The stepping motor 82 rotates the minute hand 62 via the train wheel mechanism 72. When the stepping motor 82 is driven once, the minute hand 62 rotates once by one step, and makes a round on the dial plate 3 by the operation of the stepping motor 82 360 times.

  The stepping motor 83 rotates the hour hand 63 and the 24-hour hand 64 via the train wheel mechanism 73. The train wheel mechanism 73 is configured to rotate the hour hand 63 and the 24-hour hand 64 in conjunction with each other. When the stepping motor 83 is driven once, the hour hand 63 is rotated once by one step and the 24-hour hand 64 is rotated. Is rotated by 1/2 degree. Therefore, when the hour hand 63 and the 24-hour hand 64 are rotated and moved once every 10 seconds, the hour hand 63 moves 30 degrees on the dial 3 during one hour and the 24-hour hand 64 moves within the small window 4. Move 15 degrees. That is, the hour hand 63 makes a round on the dial 3 in 12 hours, and the 24-hour hand 64 makes a round in the small window 4 in 24 hours.

  The stepping motor 84 rotates the mode indicator 66 and the date wheel 65 in conjunction with each other via the train wheel mechanism 74. When the stepping motor 84 is driven once, the mode pointer 66 is rotated once per step. For example, the date indicator 65 rotates 360/31 degrees by a rotational movement of 150 steps, and the date mark exposed from the opening 7 changes by one day. Then, when the date wheel 65 rotates 31 days, a date mark indicating the first date is exposed from the opening 7 again.

  The stepping motor 85 rotates the small minute hand 67 and the small hour hand 68 via the train wheel mechanism 75. When the stepping motor 85 is driven once, the small minute hand 67 rotates once by one step, and the small hour hand 68 rotates by 1/12 degrees. Accordingly, when the stepping motor 85 is driven to rotate 360 times, the small minute hand 67 goes around the small window 6 and the small hour hand 68 rotates 30 degrees within the small window 6.

The time hands 61 to 63, the 24-hour hand 64, the date indicator 65, the mode hand 66, the small minute hand 67, and the small hour hand 68 are not particularly limited, but are 90 pps (pulse per second) in the forward rotation direction (time advance direction). ) And can be rotated at 32 pps in the reverse direction.
The pointers 61 to 68 and the stepping motors 81 to 85 constitute display means.

  The drive circuit 51 outputs a drive pulse of a predetermined voltage to the stepping motors 81 to 85 according to a control signal from the CPU 41 to rotate the stepping motors 81 to 85 once by a predetermined angle (for example, 180 degrees). The drive circuit 51 can change the length (pulse width) of the drive pulse in accordance with the state of the analog electronic timepiece 1 or the like. In addition, when a control signal for simultaneously driving a plurality of hands is input, the output timing of the drive pulse can be slightly shifted in order to reduce the load.

Next, the setting operation in local time in the analog electronic timepiece 1 of the present embodiment will be described.
In the analog electronic timepiece 1, the local time is set manually or automatically. When these local times are set manually, the city time difference information 42b and the city daylight saving time information 42c are referred to, and the local time is set and calculated according to the city selected by the user. On the other hand, when the local time is set automatically, the time difference map 48b, the time difference information 48c, and the daylight saving time information 48d are referred to, and the local time corresponding to the current position obtained from the navigation message acquired from the positioning satellite is referred to. Is set and calculated. In addition, the settings stored in the city time difference information 42b, the city daylight saving time information 42c, and the time difference map 48b are corrected by the user's correction operation and stored as the city user correction data 43a and the map user correction data 43b. It is possible to use it.

  In the analog electronic timepiece 1, the display setting DST (AUTO) for automatically displaying the daylight saving time according to the daylight saving time implementation information related to the selected local time setting information, and the daylight saving time related to the set local time setting information. Display setting (STD) that does not display daylight saving time regardless of execution information, and display setting (DST) that causes display to shift by a set shift time (for example, 1 hour) regardless of execution information of daylight saving time Either can be selected by a user operation.

  FIG. 3 is a flowchart showing a control procedure by the CPU 41 of the local time setting process in the analog electronic timepiece 1 of this embodiment. FIG. 3A shows a control procedure of local time setting processing performed by the user manually selecting and setting a city. Here, when the user pulls out the crown C1 in two stages, the mode shifts to the city setting mode, and the crown C1 is rotated, and any one of the cities described on the peripheral portion of the dial 3 by the second hand 61. The city is selected by pointing to.

  CPU41 acquires the city selected by the user (Step S701). CPU41 discriminate | determines whether the user correction data according to the said city are memorize | stored in the city user correction data 43a (step S702). If it is determined that it is stored (“YES” in step S702), the CPU 41 refers to the city user correction data 43a and acquires time difference information and daylight saving time implementation information corresponding to the city (step S702). S703). Then, the process of the CPU 41 proceeds to step S705.

  When it is determined that the user correction data corresponding to the selected city is not stored in the city user correction data 43a ("NO" in step S702), the CPU 41 refers to the city time difference information 42b and The time zone corresponding to the city is acquired (step S713), and the daylight saving time implementation information corresponding to the city is acquired with reference to the city daylight saving time information 42c (step S714). At this time, when the user correction data related to the local time setting information of a city different from the selected city is stored in the city user correction data 43a, the CPU 41 performs a process of deleting the user correction data. Also good. Further, the CPU 41 also performs a process of deleting the user correction data even when the user correction data whose valid period has elapsed is stored. Then, the process of the CPU 41 proceeds to step S705.

  When the process proceeds to step S705, the CPU 41 calculates the local time and date to which the acquired time zone and daylight saving time are applied with respect to the date and time counted by the clock circuit 46 (step S705). Then, the CPU 41 ends the local time calculation process.

  FIG. 3B shows a control procedure of local time setting processing that is executed when positioning is performed by the satellite radio wave reception processing unit 48. Here, the satellite radio wave reception processing unit 48 receives radio waves from the positioning satellite, calculates the current position using the received navigation message, and outputs the calculation result to the CPU 41 to acquire the current position. The

  At the same time, the control unit 48a of the satellite radio wave reception processing unit 48 refers to the time difference map 48b and acquires a parameter related to the time zone and a parameter related to daylight saving time according to the calculated current position. The control unit 48a refers to the time difference information 48c to obtain a time difference (deviation time from UTC) according to the parameter related to the time zone, and refers to the daylight saving time information 48d to determine the daylight saving time according to the parameter related to daylight saving time. Implementation information, that is, information on whether or not daylight saving time is implemented, daylight saving time implementation period, and shift time from standard time during daylight saving time implementation period is acquired. And the control part 48a outputs these time zones and daylight saving time implementation information to CPU41 with the acquired present position.

  The CPU 41 acquires the current position from the satellite radio wave reception processing unit 48 (step S751). The CPU 41 determines whether or not user correction data corresponding to the current position (that is, in the area including the current position) is stored in the map user correction data 43b (step S752).

  If it is determined that the corresponding user correction data is stored in the map user correction data 43b ("YES" in step S752), the CPU 41 refers to the map user correction data 43b and refers to the time zone and daylight saving time implementation information. Is acquired (step S753). Then, the process of the CPU 41 proceeds to step S755.

  When it is determined that the corresponding user correction data is not stored in the map user correction data 43b ("NO" in step S752), the CPU 41 outputs the time zone and daylight saving time implementation information output by the satellite radio wave reception processing unit 48. Is acquired (step S763). At this time, if user correction data that does not correspond to the current position is stored in the map user correction data 43b, the CPU 41 may perform processing for deleting the user correction data. Further, even when user correction data whose valid period has elapsed is stored, the CPU 41 performs processing for deleting the user correction data. Then, the process of the CPU 41 proceeds to step S755.

  In step S755, the CPU 41 sets the local time at the current position by applying the acquired time zone and daylight saving time implementation information (step S755). That is, based on the selected and acquired local time setting information, the CPU 41 tentatively sets the local time based on the time zone (if daylight saving time implementation is switched based on the local time). Calculate once and calculate the time difference). The CPU 41 calculates the local time by applying the time difference to the date and time counted by the timing circuit 46, outputs a control signal to the drive circuit 51 as necessary, and displays it on a part of the hands 61 to 68. To do. Then, the CPU 41 ends the local time setting process.

Next, a description will be given of the input setting operation of the correction data of the time zone and daylight saving time information by the user.
FIG. 4 is a flowchart showing a control procedure by the CPU 41 of the local time setting correction process executed in the analog electronic timepiece 1 of the present embodiment.

The local time setting correction process is started when a specific user operation, for example, the crown C1 is pulled out in two stages and the push button switch B3 is further pressed for 10 seconds.
When the local time setting correction process is started, the CPU 41 determines whether position information (latitude, longitude) or city setting relating to the current position is held as a target position for correcting the local time setting information ( Step S101). If it is determined that the position information or the city setting is not held (“NO” in step S101), the CPU 41 ends the local time setting correction process.

  If it is determined that the position information or city setting is held (“YES” in step S101), the CPU 41 executes time zone setting correction processing (step S102). In addition, the CPU 41 executes a setting correction process related to daylight saving time implementation information (step S103).

  The CPU 41 outputs a control signal to the drive circuit 51, moves a part of the necessary hands out of the hands 61 to 68, shows the correction result, and confirms whether the setting can be completed by the correction. (Step S104). The CPU 41 determines whether or not a setting completion operation has been input (step S105). If it is determined that the setting completion operation has been performed, in this case, the operation in which the crown C1 is pushed back one or more steps (step S105). “YES”), the city setting and the correction setting are associated with each other and stored in the city user correction data 43a, or the current position (or the area including the current position) and the correction setting are associated with the map user correction. The data 43b is stored (step S106). At this time, when the correction data of the same city or the same area as the current position is stored, the CPU 41 overwrites and updates the previous correction data with the new setting and stores it. Then, the CPU 41 ends the local time setting correction process.

  If it is determined that an operation other than the setting completion operation has been performed (“NO” in step S105), the CPU 41 returns the process to step S102 and performs the process related to the setting again.

  FIG. 5 is a flowchart showing a control procedure by the CPU 41 of the time zone correction process called in the local time setting correction process.

  When the time zone correction process is called, the CPU 41 outputs a control signal to the drive circuit 51, rotates the pointer (second hand 61) so as to point to the city sign corresponding to the currently set time zone, Start waiting for hour digit correction operation. Then, the CPU 41 determines whether or not a time digit correcting operation, here, a rotation operation of the crown C1 has been detected (step S201). If it is determined that it has been detected (“YES” in step S201), the CPU 41 updates the hour digit value ± 1 hour according to the rotation direction of the crown C1, and outputs a control signal to the drive circuit 51. Then, the city sign corresponding to the updated value is pointed to the pointer (here, the second hand 61) (step S202). Then, the process of the CPU 41 proceeds to step S203. If it is determined in step S201 that the hour digit correction operation has not been detected ("NO" in step S201), the process of the CPU 41 proceeds to step S203.

  In the process of step S203, the CPU 41 determines whether or not an operation for ending the hour digit correcting operation, for example, a pressing operation of the push button switch B3 is detected (step S203). If it is determined that the end operation has not been performed (“NO” in step S203), the processing of the CPU 41 returns to step S201.

  If it is determined that the end operation has been performed (“YES” in step S203), the CPU 41 outputs a control signal to the drive circuit 51, and the minute digits of the time difference from the UTC time in the currently set time zone. The second hand 61 is pointed to the value of. Then, the CPU 41 determines whether or not a minute digit correcting operation, here, a rotation operation of the crown C1 has been detected (step S204). If it is determined that the minute digit correcting operation has been detected (“YES” in step S204), the CPU 41 updates the value of the minute digit in accordance with the rotation direction of the crown C1, and sends a control signal to the drive circuit 51. Is output and the updated value is indicated on the pointer (here, the second hand 61) (step S205). Here, since the time difference from the UTC time in various parts of the world is currently set only in units of 15 minutes, in the analog electronic timepiece 1, 15 minutes each time the crown C1 is rotated by one step. It can be controlled to update the minute digit value. Then, the process of the CPU 41 proceeds to step S206.

If it is determined that the minute digit correcting operation has not been detected (“NO” in step S204), the CPU 41 shifts the processing to step S206.
When the process proceeds to step S206, the CPU 41 determines whether or not an operation for ending the minute digit correcting operation, for example, a pressing operation of the push button switch B3 is detected (step S206). If it is determined that the end operation has been performed (“YES” in step S206), the CPU 41 ends the time zone correction process and returns the process to the local time setting end process. If it is determined that the end operation has not been performed (“NO” in step S206), the process of the CPU 41 returns to step S204.

  FIG. 6 is a flowchart showing a control procedure by the CPU 41 of the daylight saving time information correction process called in the local time setting correction process.

  When the daylight saving time information correction process is called, the CPU 41 outputs a control signal to the drive circuit 51 so that the mode pointer 66 points to the indicator relating to the daylight saving time setting mode currently set. Then, the CPU 41 determines whether or not a daylight saving time setting mode switching operation, for example, a push button switch B4 is pressed (step S301). If it is determined that the switching operation has been performed (“YES” in step S301), the CPU 41 changes the setting to the setting mode next to the currently set daylight saving time setting mode, and sends a control signal to the drive circuit 51. The display state corresponding to the setting is output and the position indicated by the mode pointer 66 is updated (step S302). This setting mode includes automatic daylight saving time execution mode DST (AUTO), daylight saving time non-execution mode (STD), daylight saving time manual setting mode pattern 1 (P.1), and daylight saving time manual setting mode pattern 2 (P.2). In the order of P.P. When the same operation is performed in step 2, the automatic execution mode is restored. Then, the process of the CPU 41 proceeds to step S303. If it is determined that the switching operation has not been performed (“NO” in step S301), the processing of the CPU 41 proceeds to step S303.

  When the process proceeds to step S303, the CPU 41 determines whether the current setting mode is DST (AUTO) or STD (step S303). If it is determined that the signal is either DST (AUTO) or STD (“YES” in step S303), the CPU 41 determines whether or not a mode switching end operation has been performed (step S304). When it is determined that the mode switching end operation, for example, the push button switch B3 has been pressed (“YES” in step S304), the CPU 41 ends the daylight saving time information correction processing and changes the processing to the local time setting correction processing. return. If it is determined that the mode switching end operation has not been performed (“NO” in step S304), the processing of the CPU 41 returns to step S301.

  If it is determined in the determination process in step S303 that the current setting mode is neither DST (AUTO) nor STD (P.1 or P.2) ("NO" in step S303), the CPU 41 Determines whether or not the reference time switching operation of the start time and end time of daylight saving time, for example, the pressing operation of the push button switch B1 is detected (step S311). If it is determined that the reference time switching operation has been detected (“YES” in step S311), the reference time is alternately switched between the UTC time reference and the local time reference to indicate the current setting, and driving is performed. A control signal is output to the circuit 51, and the pointer (second hand 61) is moved between the UTC mark position (12 o'clock position) and the mark position corresponding to the set time zone to indicate the current reference time. (Step S312). Then, the process of the CPU 41 returns to step S301.

  When it is determined that the reference time switching operation has not been detected (“NO” in step S311), the CPU 41 detects the shift time switching operation during daylight saving time, in this case, the rotation operation of the crown C1. It is determined whether or not (step S313). If it is determined that the shift time switching operation has been detected (“YES” in step S313), the CPU 41, for example, increases or decreases the shift time in increments of 30 minutes in accordance with the rotation direction of the crown C1. The increased or decreased shift time is indicated by the pointer (the minute hand 62 and the hour hand 63) (step S314). Then, the process of the CPU 41 returns to step S301.

  If it is determined that the shift time switching operation has not been detected (“NO” in step S313), the CPU 41 determines whether or not the mode switching end operation (pressing the push button switch B3) has been detected. A determination is made (step S315). If it is determined that the mode switching end operation has not been detected (“NO” in step S315), the process of the CPU 41 returns to step S301. If it is determined that the mode switching end operation has been detected (“YES” in step S315), the CPU 41 calls and executes the daylight saving time manual correction process (step S316), and then ends the daylight saving time information correction process. The processing is then returned to the local time setting correction processing.

7 and 8 are flowcharts showing a control procedure by the CPU 41 of the daylight saving time information manual correction process called in the daylight saving time information correction process.
When the daylight saving time information correction process is called, the CPU 41 outputs a control signal to the drive circuit 51 and causes the small minute hand 67 and the small hour hand 68 to indicate “1 o'clock” to set the daylight saving time start month and start time. In addition, the display of the daylight saving time start month (for example, the second hand 61) and the start time (for example, the hour hand 63 and the minute hand 62) that are currently set, Correction operation For example, it is determined whether or not a pressing operation of the push button switch B1 is detected (step S601). If it is determined that a correction operation for the start month has been detected (“YES” in step S601), the CPU 41 advances the start month by one month and outputs a control signal to the drive circuit 51 to proceed with the advance. The pointer (second hand 61) is pointed to the position indicating the sign corresponding to the moon (step S602). Then, the process of the CPU 41 returns to step S601.

  If it is determined that the correction operation for the start month has not been detected (“NO” in step S601), the CPU 41 determines whether the 0:00 setting related to the start time is 0:00 (the beginning of the day) or 24:00 Or (for example, the end of the day), for example, it is determined whether or not a pressing operation of the push button switch B4 has been detected (step S603). If it is determined that a switching operation has been detected (“YES” in step S603), the CPU 41 alternately switches the setting between 0:00 and 24:00, and outputs a control signal to the drive circuit 51. The mode pointer 66 is moved between corresponding positions, for example, between the 0 o'clock position and the 6 o'clock position (step S604). Then, the process of the CPU 41 returns to step S601.

  When it is determined that the switching operation between 0 o'clock and 24 o'clock has not been detected (“NO” in step S603), the CPU 41 detects a start time correcting operation, for example, a rotation operation of the crown C1. It is determined whether or not (step S605). If it is determined that the start time correction operation has been detected (“YES” in step S605), the CPU 41 changes the start time ± 1 hour in accordance with the rotation direction of the crown C1, and A control signal is output, and the minute hand 62 and the hour hand 63 are moved to the pointer position corresponding to the changed start time (step S606). Then, the process of the CPU 41 returns to step S601.

It is determined whether or not a pressing operation is detected (step S606). If it is determined that the end operation of the correction operation has not been detected (“NO” in step S606), the process of the CPU 41 returns to step S601.

  If it is determined that the operation for ending the daylight saving time start month and the operation for correcting the start time has been detected ("YES" in step S606), the CPU 41 sets the daylight saving time mode to manual mode pattern 1 (P.1). It is determined whether or not (step S607). P. When it is determined that it is 1 (“YES” in step S607), the CPU 41 shifts to the daylight saving start date correction state, outputs a control signal to the drive circuit 51, and outputs the small minute hand 67 and the small hour hand. 68 is moved to indicate the 2 o'clock position to indicate that the daylight saving time start date has been corrected, and the current daylight saving time start date is set to the second hand 61 (how many weeks) And the mode pointer 66 (day of the week). Then, the CPU 41 determines whether or not a correction operation for the start week, for example, a pressing operation of the push button switch B1 has been detected (step S611). If it is determined that the correction operation for the start week is detected (“YES” in step S611), the CPU 41 changes the start week in order from the first week to the fourth week and the last week. Then, a control signal is output to the drive circuit 51 to change the position indicated by the second hand 61 (step S612). Then, the process of the CPU 41 returns to step S611.

  When it is determined that the correction operation for the start week has not been detected (“NO” in step S611), the CPU 41 determines whether the correction operation for the start day of the week, for example, the press operation of the push button switch B4 has been detected. Is determined (step S613). When it is determined that the correction operation for the start day of the week has been detected (“YES” in step S613), the CPU 41 changes the start day of the week in order from Sunday to Saturday, and sends a control signal to the drive circuit 51. The sign indicating the day of the week that has been output and changed to the mode pointer 66 is indicated (step S614). Then, the process of the CPU 41 returns to step S611.

  When it is determined that the correction operation for the start day of the week has not been detected (“NO” in step S613), the CPU 41 detects an operation for ending the correction operation for the start date, for example, a pressing operation of the push button switch B3. It is determined whether or not it has been done (step S615). If it is determined that an operation for ending the correction operation for the start date has not been detected (“NO” in step S615), the processing of the CPU 41 returns to step S611. If it is determined that an operation for ending the correction operation for the start date has been detected (“YES” in step S615), the processing of the CPU 41 proceeds to step S631.

  If it is determined in step S608 that the mode setting is not the manual mode pattern 1 (P.1) (P.2) ("NO" in step S608), the CPU 41 starts the daylight saving time. It shifts to the date correction state, outputs a control signal to the drive circuit 51, and moves the small minute hand 67 and the small hour hand 68 so as to point to the 2 o'clock position, thereby confirming that the daylight saving time start date is being corrected. In addition, the date indicator 65 is set to perform the setting related to the currently set daylight saving time start date. Then, the CPU 41 determines whether or not an operation for correcting the start date, for example, a rotation operation of the crown C1 has been detected (step S621).

  If it is determined that the operation for correcting the start date has been detected (“YES” in step S621), the CPU 41 changes the start date by ± 1 day according to the rotation direction of the crown C1 and A control signal is output to rotate the date wheel 65 to display the changed start date (step S622).

Correction of the end month of daylight saving time after indicating that there is a display and displaying the end month (for example, second hand 61) and end time (for example, hour hand 63 and minute hand 62) of the currently set daylight saving time It is determined whether an operation, for example, a pressing operation of the push button switch B1 is detected (step S631). If it is determined that a correction operation for the end month has been detected (“YES” in step S631), the CPU 41 advances the end month by one month and outputs a control signal to the drive circuit 51 to proceed with the advance. The pointer (second hand 61) is pointed to the position where the sign corresponding to the moon is pointed (step S632). Then, the process of the CPU 41 returns to step S631.

If it is determined that a switching operation has been detected (“YES” in step S633), the CPU 41 alternately switches the setting between 0 o'clock and 24 o'clock and outputs a control signal to the drive circuit 51. The mode pointer 66 is moved to a corresponding position, for example, either the 0 o'clock position or the 6 o'clock position (step S634). Then, the process of the CPU 41 returns to step S631.

It is determined whether or not a pressing operation is detected (step S636). If it is determined that the end operation of the correction operation has not been detected (“NO” in step S636), the process of the CPU 41 returns to step S631.

  If it is determined that an operation for ending the daylight saving time end month and end time correction operation has been detected ("YES" in step S636), the CPU 41 sets the daylight saving time mode to manual mode pattern 1 (P.1). It is determined whether or not (step S637). P.

  If it is determined in step S638 that the mode setting is not the manual mode pattern 1 (P.1) (P.2) ("NO" in step S638), the CPU 41 terminates daylight saving time. Transition to the day correction state, a control signal is output to the drive circuit 51, and the small minute hand 67 and the small hour hand 68 are moved so as to indicate the "4 o'clock" position. In addition, the date indicator 65 is caused to make a setting related to the end date of the currently set daylight saving time.

9 to 11 are diagrams showing display examples when the local time setting correction process is executed in the analog electronic timepiece 1 of the present embodiment.
When the local time setting correction process is started, the second hand 61 is pointed with a sign relating to the city corresponding to the hour digit in the current time zone (step S101). Here, the second hand 61 indicates the city sign “TYO”, that is, +9 hours, which is the time difference of Tokyo (FIG. 9A). By rotating the crown C1 in this state, the second hand 61 is moved to the position of the city sign whose time zone is different by one hour for each rotation of the crown C1 in one step (steps S201 and S202). That is, here, the location of the city sign whose value is in minutes (+5 hours 30 minutes) is skipped as in New Delhi indicated by the city sign “DEL”.

  When the pushbutton switch B3 is pressed to complete the time zone hour digit correction operation (step S203), the second hand 61 indicates the 0-minute position, so that the minute digit included in the time difference from the UTC time at the current position is displayed. The value is shown (FIG. 9 (b)). By rotating the crown C1 in this state, the minute digit is changed by 15 minutes every time the crown C1 is rotated by one step, and the second hand 61 is moved by 15 seconds (step S204). , S205).

  When the push button switch B3 is pressed and the operation for correcting the minute digits of the time zone is completed (step S206), the time hands 61 to 63 are all arranged in the 12 o'clock direction, and the mode hand 66 is located in the small window 4. To indicate any of the signs related to daylight saving time. Here, the mode pointer 66 points to the sign “AT” indicating DST (AUTO) (FIG. 9C).

  Here, each time the push button switch B4 is pressed, the mode pointer 66 is predetermined clockwise from the position of the sign “AT” to the positions “STD” and “DST” and the position “DST”. The position is sequentially moved to the position advanced by the angle (steps S301 and S302). As described above, the daylight saving time manual setting includes the pattern 1 related to the setting of the day of the week and the pattern 2 related to the setting of the date. Here, the position of “DST” indicates the pattern 1, and “DST” The position advanced in the forward rotation direction from the position “” indicates the pattern 2.

  In the state of pattern 1, as shown in FIG. 9D, the shift time during the daylight saving time is displayed by the minute hand 62 and the hour hand 63, and the reference time for switching is displayed by the second hand 61 (step S303). Here, the hour hand 63 indicates the 1 o'clock direction and the minute hand 62 indicates the 12:00 (0 minute) direction, which indicates that the shift time is 1 hour. Further, the second hand 61 indicates the city sign “TYO”, which indicates that the start and end timings of daylight saving time are defined based on the local time in Tokyo. When the push button switch B1 is pressed in this state (step S311), the reference time of switching is alternately switched between “UTC” and the second hand 61 is moved to the side where the switching has been performed (step S311). In addition, every time the crown C1 is rotated step by step (step S313), the shift time is switched and the minute hand 62 and the hour hand 63 are moved (step S314). In the case of pattern 2, the same display and operation are performed except for the position of the mode pointer 66.

  When the push button switch B3 is pressed, the mode switching end operation ends (steps S304 and S315). When the mode switching end operation ends in the mode 1 or mode 2, the mode shifts to the daylight saving time start month and start time setting state. This setting state is represented by the 1 o'clock direction being indicated in the small window 6 by the small hour hand 68. In this set state, the 3 o'clock position is indicated by the second hand 61 to indicate that the starting month is March, and the minute hand 62 and the hour hand 63 are indicated to indicate the position of 2 o'clock. It is indicated that the time is 2:00 and that the mode pointer 66 points upward (90 ° north latitude) (FIG. 10A), and the start time is “0 hour”. It is shown. In this state, when the push button switch B1 is pressed, the start month is sequentially changed and the second hand 61 is moved. In addition, when the push button switch B4 is pressed, the start time is switched between 0:00 and 24:00, and the direction indicated by the mode pointer 66 is switched between 90 degrees north latitude and 90 degrees south latitude. When the crown C1 is rotated, the start time is changed by a predetermined time (for example, 1 hour) for each rotation operation, and the direction indicated by the hour hand 63 is moved ( Steps S601 to S606).

  In the setting state of the start month and start time, when the push button switch B1 is pressed to finish the setting (step S607), the start date is set and the small hour hand 68 indicates the 2 o'clock direction. In the pattern 1, the state shifts to a state in which the daylight saving time start date is set in the day of the week, and in the pattern 2, the state shifts to a state in which the daylight saving time start date is set in the date (step S608). In the case of pattern 1, as shown in FIG. 10 (b), when the second hand 61 indicates one of the directions from 1 to 5 o'clock, the start date is from the first week to the fourth week or the last. Indicates a week. Further, the mode pointer 66 indicates one of the signs “SU” to “SA” in the area 5 to indicate the start day of the week. Here, the second hand 61 indicates the 2 o'clock position, and the mode pointer 66 indicates the sign “SU”, which indicates that the second Sunday is the start date. When the push button switch B1 is pressed in this state, the week of the start date is changed in order and the second hand 61 is moved, and when the push button switch B4 is pressed, the start day of the week is changed in order. The mode pointer 66 is moved (steps S611 to S614).

  When the end date is corrected by pressing the push button switch B3 in the end date setting state (“YES” in steps S645 and S653), the screen shifts to a time zone and daylight saving time correction confirmation screen. When the correction is completed by performing an operation of pushing back one or more steps from the state where C1 is pulled out in two steps, the corrected setting is reflected and stored in the city user correction data 43a or the map user correction data 43b.

As described above, the analog electronic timepiece 1 according to the present embodiment includes the city time difference information 42b, the city daylight saving time, which stores the local time information corresponding to each of a plurality of preset geographical locations in association with the geographical location. Information 42c, time difference map 48b, time difference information 48c, daylight saving time information 48d, and CPU 41 are provided. The CPU 41 refers to the update information acquisition means for acquiring user correction data related to the local time information of the region including the current position, and the user correction data when the user correction data corresponding to the current position is acquired. And local time setting means for setting the local time with reference to the local time information when the user correction data is not acquired.
That is, in the analog electronic timepiece 1, when the local time setting in the area where the user wants to acquire the local time is updated, the updated local time setting information is acquired as user correction data by a user operation, and the user correction data Is continuously used. Therefore, it is possible to easily and continuously respond to changes in the time zone setting and the daylight saving time setting, and to obtain accurate local time.

  The local time setting information includes information related to the time zone and daylight saving time implementation information, and the effective geographical range of the user correction data is based on the range in which daylight saving time implementation information corresponding to the current position is valid. Since it is set, the effective range can be easily determined, and the local time reflecting the accurate local time setting information can be obtained by simple processing.

  In addition, a satellite radio wave reception processing unit 48 that acquires information related to the current position is provided, and the CPU 41 as the local time setting means determines the acquired current position as an application target position of the local time setting information. When it is done, the local time setting information corresponding to the current position is quickly acquired.

  In addition, the satellite radio wave reception processing unit 48 includes a receiving unit that receives radio waves from the positioning satellites and a position calculation unit that calculates the current position based on the received radio waves. It is possible to easily and accurately acquire the current position in various parts of the world where radio waves can be received and select the local time setting information corresponding to the current position to acquire the local time.

  Further, the CPU 41 as the update information acquisition unit associates the effective range of the daylight saving time implementation information corresponding to the acquired current position with the user correction data. Accordingly, the user can appropriately store the local time setting information in the area including the current position in the RAM 43 by simply performing the user correction data setting operation at the current position in a situation where the current position is acquired in advance. It can be used continuously.

  The CPU 41 as the local time setting means includes the RAM 43 (city user correction data 43a and map user correction data 43b) as update information storage means for storing user correction data acquired most recently. Is not in the area associated with the user correction data, the city time difference information 42b and city daylight saving time information 42c in the ROM 42 or the time difference map 48b, time difference information 48c and daylight saving time information 48d without referring to the user correction data. The CPU 41 as the update information acquisition unit deletes the user correction data that has not been referred to. Therefore, it is possible to prevent the user correction data from being constantly maintained, particularly when the effective range of the normal daylight saving time implementation information is different from the effective range of the local time setting information corresponding to the user correction data. In addition, by minimizing the storage data in this way, the capacity of the RAM 43 can be suppressed, and the operation of referring to unnecessary user correction data in the local time setting process can be reduced.

  In addition, an operation unit 47 that receives a user operation is provided, and the CPU 41 as a current position acquisition unit currently selects one of the world cities set in advance according to the input operation received by the operation unit 47. Get as position. Therefore, it is possible for the user to determine an appropriate current position without inputting detailed position information, and the latest local time setting information corresponding to the current position can be easily and appropriately used for accurate local time. Can be obtained.

  In addition, by representing the geographical position to be selected by the city name, the user can select the current position more easily and intuitively.

  In addition, an operation unit 47 that receives a user operation is provided, and the CPU 41 as the update information acquisition unit acquires user correction data according to the content of the user operation received by the operation unit 47. Therefore, in an electronic timepiece that is difficult to update the entire local time setting information to the latest one, or to obtain the necessary local time setting information automatically in real time, because the restrictions on communication with the outside are large. The latest local time setting information in the required area can be easily obtained, and the changed setting can be used continuously, so that the user can save time and effort related to the local time setting. You can get the time.

  Further, the user correction data can include information related to the validity period of the user correction data. Therefore, it is possible to save the trouble of releasing after setting temporary setting by timed legislation or temporary display for the convenience of the user, and obtaining accurate local time across the valid period. I can do it.

The analog electronic timepiece 1 also includes a clock circuit 46 that counts the date and time, hands 61 to 68 for displaying the date and time, and stepping motors 81 to 85. The CPU 41 serving as the local time calculating means converts the date and time counted by the clock circuit 46 in accordance with the local time setting performed as the local time setting means, and displays the converted local time using the hands 61 to 68. .
That is, the analog electronic timepiece 1 can easily and continuously calculate and display the accurate local time according to the updated local time setting information, so that the user can display the local time held by the analog electronic timepiece 1. Even after the initial data of the setting information has been changed, accurate local time can be obtained continuously throughout the world.

The present invention is not limited to the above-described embodiment, and various modifications can be made.
For example, in the above embodiment, the case where the setting and the local time display are performed in the analog electronic timepiece has been described, but the digital electronic timepiece having a digital display screen or the electronic timepiece in which the digital display screen and the pointer display are used in combination. There may be. In this case, a setting state, a mode, or the like may be displayed according to the size of the digital display screen, the number of displayable characters, or the like, or a setting correction method may be displayed.

  In the above embodiment, the user correction data once set is valid until different settings are made for the same region or city, or until local time information for another region or city is referred to. In the above description, the case where the setting is valid until the validity period elapses has been described. However, the user correction data may include a flag that determines whether the setting data is valid or invalid. Further, the user correction data itself set once may be read and corrected.

  In the above embodiment, the same corrected local time setting information (user correction data) is used for the current position acquired in the parameter setting area related to the same daylight saving time. The same local time setting information corrected only at the current position in a predetermined number of geographic blocks in one or the vicinity may be used.

  In the above embodiment, the correction of the time zone and the correction of the daylight saving time execution information are performed continuously, but only one of them may be corrected. In this case, the time zone and daylight saving time implementation information separately corrected for the same region can be collectively stored in the map user correction data 43b as one setting.

  In the above embodiment, the local time setting information for the acquired current position is corrected. However, it is different from the current position by inputting the correction position information and the local time setting information together. The local time setting information at the position may be correctable. For example, if it is determined in the local time setting correction process that the current position is not held in the determination process in step S101, the process proceeds to a process of acquiring information on the correction target position, and after the target position is acquired You may progress to the process after step S102.

  In the above embodiment, both local time setting based on the city setting and local time setting based on the radio wave reception of the positioning satellite are possible, but either one may be used. In addition, even when setting manually, it may be possible to set latitude and longitude by input operation instead of city setting, and even if city setting is made, a table for converting the setting to latitude and longitude is held. The local time setting information of the geographic block to which the latitude and longitude belong may be performed in the same manner as in the case of receiving radio waves from the positioning satellite. That is, in this case, the correction data of the local time setting information for the city selection and the correction data of the local time setting information for the positioning result are shared, so even if the current position acquisition by both is mixed, the other setting is Not invalidated. Such a form may be appropriately determined according to the capacity of the storage unit in the RAM 43 and the satellite radio wave reception processing unit 48, the processing capability of the CPU 41 and the control unit 48a, and the like.

  Further, in the above embodiment, the city time difference information 42b and city daylight saving time information 42c relating to the city setting, the city user correction data 43a and the map user correction data 43b which are correction data by the user are stored in the ROM 42 on the main body side of the analog electronic timepiece 1. Or a RAM 43 that stores and uses a time difference map 48b, time difference information 48c, and daylight saving time information 48d relating to local time setting information based on radio wave reception from a positioning satellite, which is arranged in a module of the satellite radio wave reception processing unit 48. However, the data may be stored in one place. Further, the local time setting process does not have to be performed in a distributed manner between the control unit 48a of the satellite radio wave reception processing unit 48 and the CPU 41, and may be performed independently by the control unit 48a of the CPU 41 or the satellite radio wave reception processing unit 48. .

  Moreover, in the said embodiment, although the city user correction data 43a and the map user correction data 43b were updated according to the user operation received by the operation part 47, the update information in such few areas is Bluetooth communication. It may be acquired from an external device such as a smartphone via short-range wireless communication such as (registered trademark: Bluetooth). In this case, detailed update settings can be more easily performed and transmitted to the analog electronic timepiece 1 in an external device such as a smartphone.

In the above-described embodiment, positioning is performed by receiving radio waves from GPS satellites. However, radio waves from positioning satellites related to other positioning systems, for example, GLONASS and GALILEO are used or used together. Position information may be acquired.
In addition, the specific details of the above-described embodiment, such as the configuration of the electronic timepiece, the content and procedure of the processing, can be changed as appropriate without departing from the spirit of the present invention.
