The push button switches B1 to B4 and the crown C1 accept the user's operation and output an electric signal to the CPU 41 (see FIG. 2) as an operation reception signal. The push button switches B1 to B4 output an operation acceptance signal according to a push operation based on a user operation or the like. Further, the crown C1 is pulled out and is rotatably provided in the pulled out state. The crown C1 is capable of a two-step withdrawal operation, and outputs an operation reception signal corresponding to each of a pull-out operation, a push-back operation, and a rotation operation based on a user operation or the like to the CPU 41.

FIG. 2 is a block diagram showing a functional configuration of the electronic clock 1 of the present embodiment.
The electronic clock 1 includes a CPU 41 (control unit), a ROM 42 (marking information storage unit), a RAM 43, an oscillation circuit 44, a frequency dividing circuit 45, a timekeeping circuit 46 (timekeeping unit), an operation reception unit 47, and the like. The communication unit 48, the satellite radio wave reception processing unit 49 (position acquisition unit, positioning operation unit), the antenna AN, the drive circuit 50, the power supply unit 70, the train wheel mechanism 61 to 64, and the stepping motors 51 to 54. , The above-mentioned guidelines 11 to 15 and the like are provided.

The CPU 41 is a processor that performs various arithmetic processes and controls the overall operation of the electronic clock 1. The CPU 41 controls the pointer operation related to the display of the date and time. The CPU 41 converts the date and time counted by the timekeeping circuit 46 into an appropriate local time based on the local time setting consisting of the time zone and daylight saving time implementation information, and in the normal time display mode, the converted local time is converted by the pointers 11 to 15. Display.
Further, the CPU 41 operates the communication unit 48 and the satellite radio wave reception processing unit 49 to acquire the date and time, position information, various setting data, and the like. The CPU 41 corrects the date and time counted by the timekeeping circuit 46 based on the obtained date and time data.

The ROM 42 stores various control programs 42a and setting data executed by the CPU 41. The program 42a includes, for example, a program related to operation control of various functional modes. Further, the setting data includes city time difference information 42b and updated city time difference information 42c (both of these are collectively time difference information). The ROM 42 includes a non-volatile memory such as a flash memory that can be partially rewritten (time difference information can be updated and stored from the initial setting) and an EEPROM (Electrically Erasable and Programmable Read Only Memory), and setting data and the like can be updated. ..

The city time difference information 42b includes the ID of the local time sign provided on the outer edge of the bezel 4, the position of the local time sign (for example, the number of steps by the second hand 11 from the 12 o'clock direction), and the time difference from the UTC time (time). Information related to the zone, thereafter, the time difference represents the time difference from the UTC time) is associated and stored as time zone setting information. In addition, the city time difference information 42b may store daylight saving time implementation information such as whether or not daylight saving time is implemented in the set city, the daylight saving time implementation period, and the shift time during implementation. Alternatively, the daylight saving time implementation information may be held as separate table data. It is desirable that the number of bits used for the ID of the local time indicator and the maximum number of time zones that can be set are provided with a margin for the newly set and added time zones.
The latest updated data of the city time difference information 42b is stored in the updated city time difference information 42c. The format of the updated city time difference information 42c is the same as that of the city time difference information 42b.

FIG. 3 is a chart showing an example of the city time difference information 42b and the updated city time difference information 42c. For example, as shown in FIG. 3A, in the city time difference information 42b, the position “28 (TYO” of the local time sign “TYO” provided at the position 28 seconds with respect to the ID “14” related to Tokyo. "Seconds)" and "+9:00 (hours)", which is the time difference, are stored in association with each other. In addition, the position "26 (seconds)" of the local time sign "HKG" provided at the position of 26 seconds for the ID "13" related to Hong Kong, and the time difference "+8:00 (hours)". Are associated and stored.

After that, for example, when the time difference in Tokyo is changed to "+8:00 (hours)" and the updated city time difference information 42c is acquired, the ID "14" relating to Tokyo is obtained as shown in FIG. 3 (b). The time difference associated with and stored is changed to "+8:00 (time)" and held. That is, in this case, in both Hong Kong and Tokyo, the time difference is +8 hours, and there is no local time sign corresponding to the time zone with the time difference of +9 hours on the bezel 4.

The storage area of the city time difference information 42b and the storage area of the updated city time difference information 42c can be configured to be alternately defined. That is, the content updated two times before is retained as the city time difference information 42b, the latest updated content is retained as the updated city time difference information 42c, and the data of the city time difference information 42b is overwritten and updated at the next update. The new updated city time difference information 42c is used, and the conventional updated city time difference information 42c is changed to the city time difference information 42b as it is.

The RAM 43 provides a working memory space to the CPU 41 and stores temporary data. Further, the RAM 43 stores the clock setting information 43a including the date / time information and the history of acquiring the position information, the update history of the updated city time difference information 42c, the normal basic clock display and the local time setting information related to the world clock display, and the pointer position. The data to be shown is stored.

The clock setting information 43a contains setting information for calculating the local time from the UTC date and time, such as the currently set home position (that is, the current position), the time zone at the world clock position, and the daylight saving time implementation rule. It is stored as setting data. Further, when the current position information is acquired by the satellite radio wave reception processing unit 49 and used for the home position setting, the current position information is included in the clock setting information 43a.

The oscillation circuit 44 generates and outputs a predetermined frequency signal. The oscillation circuit 44 includes, for example, a crystal oscillator as an 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 and the timekeeping circuit 46, and outputs the frequency signal. The output frequency may be changed and set by the control signal from the CPU 41.

The timekeeping circuit 46 counts the current date and time by counting and adding the number of frequency division signals input from the frequency dividing circuit 45 to the initial value indicating a predetermined date and time. The date and time counted by the timekeeping circuit 46 may include an error (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 timekeeping circuit 46 can be corrected by a control signal from the CPU 41. The date and time counted by the timekeeping circuit 46 may be a unique count value that can be converted into a reference date and time such as the UTC date and time, or the UTC date and time itself may be counted. Alternatively, every time the home position is set, it may be corrected and counted at the local time at the home position. The timekeeping circuit 46 may have a counter circuit as a hardware configuration, or may have a mode in which the value counted by software is stored in a RAM or the like. Further, the software-like counting may be controlled by the CPU 41 or may be controlled separately.

The operation reception unit 47 receives an input operation from the user. The operation receiving unit 47 includes the push button switches B1 to B4 and the crown C1 described above. When the push button switches B1 to B4 are pressed, the crown C1 is pulled out and pushed back, and the rotation operation is performed, an electric signal corresponding to the operation type is output to the CPU 41. In the electronic clock 1 of the present embodiment, the home position setting and the world clock position setting are changed based on the input operation from the user, both settings are exchanged, and daylight saving time is applied to the date and time in the set time zone. It is possible to switch the setting related to the presence / absence.

The communication unit 48 has an interface for communicating with an external electronic device (external device). The communication unit 48 makes a communication connection with an external device according to a communication standard of wireless communication such as Bluetooth (registered trademark: Bluetooth), and transmits / receives communication data. The new information held as the updated city time difference information 42c can be acquired by the communication unit 48 from a predetermined data server via an external device such as a smartphone.

The satellite radio wave reception processing unit 49 receives radio waves from positioning satellites including at least positioning satellites (GPS satellites) related to GPS (Global Positioning System) using the antenna AN, and the spectrum-spread transmission radio waves from these positioning satellites. Is demolished to decode and decode the signal (navigation message data). The satellite radio wave reception processing unit 49 performs various arithmetic processing on the content of the navigation message data decoded as necessary, and according to the request from the CPU 41, the date and time, the current position data, and the local time according to the current position. The setting information is acquired, and at least a part of them is output to the CPU 41 in a preset format.

The satellite radio wave reception processing unit 49 includes a reception unit 49a, a control unit 49b, a storage unit 49c, and the like. The receiving unit 49a has a receiving circuit related to amplification, tuning, demodulation, and the like of the received radio wave from the positioning satellite. The control unit 49b includes a CPU, RAM, and the like, and performs operation control related to reception, decoding, calculation, and output. The arithmetic processing of the control unit 49b includes acquisition processing of date and time data and positioning arithmetic. The positioning operation by the control unit 49b is not limited to the case where it is executed by the CPU as software, and at least a part of the processing by the dedicated hardware circuit or the like may be included.

A non-volatile memory such as a flash memory or an EEPROM (Electrically Erasable and Programmable Read Only Memory) is used in the storage unit 49c, and the stored contents are stored regardless of the power supply state to the satellite radio wave reception processing unit 49. In the storage unit 49c, in addition to setting data such as various motion control programs, predicted orbit information of each positioning satellite acquired from the positioning satellite, and the correction value for the Uru-second, the local time setting according to the current position obtained by the positioning is performed. Data tables such as a time difference map 491c, a time difference information 492c, and a summer time information 493c for obtaining information are stored. It should be noted that these data tables may be stored in the RAM 43 of the electronic clock 1, and the control unit 49b may receive a part thereof from the CPU 41 or have the CPU 41 perform necessary processing as needed. Further, the operation control program may be stored in a dedicated ROM, read out at startup, and loaded into the RAM of the control unit 49b.

The time difference map 491c is map data in which the world map is divided into appropriate geographic blocks, and parameters related to the time zone to which the geographic blocks belong and parameters related to the daylight saving time implementation rule in the geographic block are stored. The map of the time difference map 491c is not particularly limited, but a map in which the latitude line and the longitude line are represented by straight lines and drawn so as to be orthogonal to each other is preferably used, and each geographic block has a predetermined latitude interval and longitude. It is preferable that they are arranged in a two-dimensional matrix at intervals. This makes it possible to easily identify the geographic block to which the obtained current position belongs. Further, the geographic block may be determined so that the actual size does not differ significantly between the geographic blocks by making the longitude width different between the high latitude area and the low latitude area.

The time difference information 492c is table data for associating the parameter related to the time zone used in the time difference map 491c with the time difference in the time zone. In this table data, the parameters are uniquely set, for example, the time difference corresponding to the parameter "0" is "+0 hours" and the time difference corresponding to the parameter "1" is "+15 minutes".

Further, the daylight saving time information 493c is table data for associating the parameters related to the daylight saving time implementation rule used in the time difference map 491c with the contents of the daylight saving time implementation rule (implementation / non-implementation, implementation period, shift time at the time of implementation). For example, the parameter "0" is associated with no daylight saving time implementation, and the parameter "1" is that daylight saving time is +1 hour from 1:00 am on the last Sunday in March to 1:00 am on the last Sunday in October in UTC. It is set in association with the case implemented in.
In this way, the combination of the parameters related to the time zone and the parameters related to the daylight saving time implementation rule is determined for each geographic block.

Alternatively, in the time difference map 491c, only the area code is simply set according to the administrative division, etc., and in the time difference information 492c and the daylight saving time information 493c, the area number and the time zone or daylight saving time to which the administrative division corresponding to this area number belongs. The contents indicating the implementation rules may be associated with each other, or may be further associated with the numbers corresponding to the contents.
The geographic blocks and area numbers defined on these time difference maps 491c can be associated with the cities and regions defined by the city time difference information 42b and the updated city time difference information 42c. Here, it is simply associated with a city or region in the same time zone as the identified geographic block or region number.

The time difference map 491c, the time difference information 492c, and the daylight saving time information 493c can be updated. In the electronic clock 1, these updated data are acquired and overwritten and updated by communication with an external device by the communication unit 48. In addition, similar to the above-mentioned updated city time difference information 42c, two areas for storing these data are provided, and the latest data is alternately written so that the latest data and the previous data can be parallelized. It may be held.

Each configuration of these satellite radio wave reception processing units 49 is collectively formed on a chip as one module and connected to the CPU 41. The operation of the satellite radio wave reception processing unit 49 is controlled by the CPU 41 to be turned on and off independently of the operation of each other unit of the electronic clock 1. In the electronic clock 1, when it is not necessary to operate the satellite radio wave reception processing unit 49, the power supply to the satellite radio wave reception processing unit 49 is interrupted to save power.

The stepping motor 51 rotates the second hand 11 via the train wheel mechanism 61, which is an array of a plurality of gears. When the stepping motor 51 is driven once, the second hand 11 rotates 6 degrees in one step, and the stepping motor 51 makes one round on the dial 3 by the operation of the stepping motor 51 60 times.
The stepping motor 52 rotates the minute hand 12 via the train wheel mechanism 62. When the stepping motor 52 is driven once, the minute hand 12 rotates once per step, and the stepping motor 52 operates 360 times to make a round on the dial 3.

The stepping motor 53 rotates the hour hand 13 via the train wheel mechanism 63. When the stepping motor 53 is driven once, the hour hand 13 rotates once per step, and the stepping motor 53 operates 360 times to make a full turn on the dial 3.

The stepping motor 54 rotates the mode pointer 14 and the date wheel 15 in conjunction with each other via the train wheel mechanism 64. When the stepping motor 54 is driven once, the mode pointer 14 is rotated 6 degrees per step. For example, the date wheel 15 is rotated by 360/31 degrees by a rotation operation of 180 steps, and the date sign exposed from the opening 3a is changed by one day. Then, when the date wheel 15 is rotated for 31 days, the date sign indicating the first date is exposed again from the opening 3a. Since the rotation angle ratio between the mode pointer 14 and the date wheel 15 per step is very large, the date wheel 15 does not rotate significantly even if the mode pointer 14 rotates a little. When changing the date displayed by the date wheel 15, the mode pointer 14 may be operated a plurality of times.

The pointers 11 to 15 are not particularly limited, but can rotate at 90 pps (pulse per second) in the forward rotation direction (direction in which the time advances), and can rotate at 32 pps in the reverse direction. ..

The drive circuit 50 outputs a drive pulse of a predetermined voltage to the stepping motors 51 to 54 according to a control signal from the CPU 41 to rotate the stepping motors 51 to 54 in a predetermined angle (for example, 180 degrees) step. The drive circuit 50 can change the length (pulse width) of the drive pulse according to the state of the electronic clock 1 and the like. Further, when a control signal for driving a plurality of pointers at the same time is input, the output timing of the drive pulse can be slightly shifted in order to reduce the load.

The power supply unit 70 supplies electric power from the battery at a predetermined voltage related to the operation of each unit. The power supply unit 70 includes, for example, a solar panel and a secondary battery as batteries. Alternatively, the power supply unit 70 may obtain power from a replaceable button-type dry battery to supply power to each unit. When a plurality of different voltages are output from the power supply unit 70, for example, a switching power supply or the like can be used to convert the voltage into a desired voltage and output the voltage.

Next, the local time setting operation in the electronic clock 1 of the present embodiment will be described.
In the electronic clock 1, the basic clock that displays the local time at the current position (home position) and the world clock that displays the local time at a predetermined point (world clock position) in the specified world are switched as the date and time to be displayed. It is possible to set these home position and world clock position independently. Of these, the home position can be automatically set according to the current position information earned by the operation of the satellite radio wave reception processing unit 49.

Further, the home position and the world clock position can be manually set by the user's operation without acquiring the current position information. In the electronic clock 1 of the present embodiment, the urban areas stored in the above-mentioned urban time difference information 42b and the updated urban time difference information 42c, that is, the urban areas corresponding to the local time signs provided on the bezel 4 are located at these positions. For positions other than these, it is possible to count and display the basic clock and the world clock directly by setting the local time, that is, the time difference.

Further, in the electronic clock 1, it is possible to exchange the clock setting information related to the basic clock function and the clock setting information related to the world clock function, that is, to exchange between the home position and the world clock position. ..

First, the automatic setting of the home position by receiving the radio wave of the positioning satellite will be described.
FIG. 4 is a flowchart showing a control procedure by the CPU 41 for the current position acquisition setting process.
This current position acquisition setting process is started by a specific input operation by the user, in which the push button switch B4 is continuously pressed for 3 seconds or longer. Alternatively, it may be automatically activated under predetermined conditions, for example, once a day at a predetermined timing.

When the current position acquisition setting process is started, the CPU 41 requests the satellite radio wave reception processing unit 49 for date and time information and clock setting information (current position information and local time setting information) related to the basic clock (step S601). .. The CPU 41 then waits for an input from the satellite radio wave reception processing unit 49, and a time difference based on the date and time acquired based on the radio wave reception from the positioning satellite, the positioning result (obtained current position information), and the current position information. Local time setting information obtained from the map 491c, the time difference information 492c, and the summer time information 493c is acquired from the satellite radio wave reception processing unit 49 and stored in the clock setting information 43a as the clock setting related to the basic clock (step S602). The CPU 41 corrects the counting date and time of the timekeeping circuit 46 (step S603).

The CPU 41 determines whether or not the clock setting information has been normally acquired by the satellite radio wave reception processing unit 49 (step S604). If it is determined that the signal has been acquired (“YES” in step S604), the CPU 41 outputs a control signal to the drive circuit 50, causes the second hand 11 to indicate the sign “Y”, and causes the mode pointer 14 to indicate the sign “P”. "(Step S605). Then, the process of the CPU 41 shifts to step S606.

If it is determined that the clock setting information has not been acquired normally (“NO” in step S604), the CPU 41 outputs a control signal to the drive circuit 50 and is provided on the second hand 11 on the peripheral edge of the dial 3. The sign "N" is indicated (step S611). The CPU 41 determines whether or not the current position information has been held before the start of the current position acquisition setting process (step S612). When it is determined that the holding is held (“YES” in step S612), the CPU 41 outputs a control signal to the drive circuit 50 to cause the mode pointer 14 to indicate the sign “P” (step S613), and performs the process. The process proceeds to step S606. If it is determined that it is not held (“NO” in step S612), the CPU 41 outputs a control signal to the drive circuit 50 and causes the mode pointer 14 to indicate the sign “N” in the small window 3b (“N” in the small window 3b. Step S614), the process shifts to step S606.

When shifting to the process of step S606, the CPU 41 waits for a predetermined time, for example, 2 seconds (step S606). The CPU 41 identifies the local time indicator of the urban area corresponding to the acquired local time setting information (time zone) (step S607). If there is no corresponding urban area, the CPU 41 selects the exception sign as the corresponding local time sign. The CPU 41 can perform the process of step S607 during the standby time of step S606.

The CPU 41 outputs a control signal to the drive circuit 50, and displays the identified local time indicator (which was associated with the conventional local time setting information when branched to “NO” in step S604) to the second hand 11. (Step S608). The CPU 41 can additionally store the newly identified local time indicator (ID) in the clock setting information 43a.

The CPU 41 outputs a control signal to the drive circuit 50 and causes the hour and minute hands 12 and 13 to display the current local time (step S609). Further, when the date changes during the display of the local time, the CPU 41 orbits the date wheel 15 to adjust both the date and the position indicated by the mode pointer 14 to the correct position. The CPU 41 waits for a predetermined time (step S610), and then ends the current position acquisition setting process.

Next, the manual setting of the home position and the world clock position will be described. In the electronic clock 1, the crown C1 is pulled out one step or two steps to shift to the manual setting state of the home position and the world clock position, respectively. Then, the second hand 11 is moved according to the rotational operation of the crown C1 to point to the local time sign of the desired urban area, thereby setting the time zone.

FIG. 5 is a flowchart showing a control procedure by the CPU 41 of the local time manual setting process.
This local time manual setting process is started when the withdrawal operation of the crown C1 is detected.

When the local time manual setting process is started, the CPU 41 determines whether or not the crown C1 is in the one-step withdrawal state (step S501). When it is determined that the state is one-step withdrawn (“YES” in step S501), the CPU 41 reads and acquires the clock setting information related to the world clock, outputs a control signal to the drive circuit 50, and outputs the control signal. The hour and minute hands 12 and 13 indicate the current time (local time) according to the local time setting information related to the world clock. Further, the CPU 41 causes the second hand 11 to indicate a local time sign (an exception sign if there is no corresponding local time sign) in the urban area according to the time zone of the world clock position (step S502). At this time, the CPU 41 can also rotate the date wheel 15 to display the correct date.

The CPU 41 determines whether or not the current position information is included in the clock setting information related to the world clock (step S503). If it is determined to be included (“YES” in step S503), the CPU 41 outputs a control signal to the drive circuit 50 to cause the mode pointer 14 to indicate the sign “P” (step S506), and then , The process shifts to step S508. If it is determined that it is not included (“NO” in step S503), the CPU 41 outputs a control signal to the drive circuit 50 to cause the mode pointer 14 to indicate the sign “N” (step S507), and then , The process shifts to step S508.

When it is determined that the crown C1 is not in the one-step withdrawal state, that is, in the two-step withdrawal state (“NO” in step S501), the CPU 41 reads out the clock setting information related to the basic clock. A control signal is output to the drive circuit 50, and the current local time corresponding to the local time setting information related to the basic clock is indicated by the hour and minute hands 12 and 13. Further, the CPU 41 causes the second hand 11 to indicate a local time sign (an exception sign if there is no corresponding local time sign) in the urban area according to the time zone of the home position (step S504).

The CPU 41 determines whether or not the current position information is included in the clock setting information related to the basic clock (step S505). If it is determined to be included (“YES” in step S505), the CPU 41 outputs a control signal to the drive circuit 50 to cause the mode pointer 14 to indicate the sign “P” (step S506), and then , The process shifts to step S508. If it is determined that it is not included (“NO” in step S505), the CPU 41 outputs a control signal to the drive circuit 50 to cause the mode pointer 14 to indicate the sign “N” (step S507), and then , The process shifts to step S508.

When the process of steps S506 and S507 shifts to the process of step S508, the CPU 41 determines whether or not the operation of pulling out or pushing back the crown C1 is detected (step S508). If it is determined that it has not been detected (“NO” in step S508), the CPU 41 determines whether or not the push button switch B3 is continuously pressed for 1 second or longer (step S509). If it is determined that the button has been pressed continuously for 1 second or longer (“YES” in step S509), the CPU 41 executes the time difference manual setting process described later (step S520), and then shifts the process to step S524. ..

When it is determined that the push button switch B3 has not been continuously pressed for 1 second or longer (“NO” in step S509), the CPU 41 detects the rotation operation of the crown C1 (first input operation). It is determined whether or not the button is present (step S510). If it is determined that it has not been detected (“NO” in step S510), the processing of the CPU 41 returns to step S508.

When it is determined that the rotation operation of the crown C1 is detected (“YES” in step S510), the CPU 41 presents the current position in the clock setting information about the clock function (basic clock / world clock) being displayed and set. It is determined whether or not the information is included (step S511). If it is determined that it is included (“YES” in step S511), the current position information is deleted, a control signal is output to the drive circuit 50, and the mode pointer 14 is indicated by the sign “N” in the small window 3b. (Step S512). Then, the process of the CPU 41 shifts to step S513. If it is determined that the current position information is not included (“NO” in step S511), the processing of the CPU 41 proceeds to step S513.

When the process proceeds to step S513, the CPU 41 outputs a control signal to the drive circuit 50, and the detected local time indicator is provided next to the currently selected local time indicator in the rotation direction of the crown C1. Move the second hand 11 to the position of. That is, when the local time sign next to the rotation direction is an exception sign, the CPU 41 skips this exception sign and moves the second hand 11 by 4 steps, and a position sign indicating a normal urban area or a reference sign indicating a UTC. In the case of, the second hand 11 is moved by two steps. Further, the CPU 41 acquires the time difference of the city (region) corresponding to the local time indicator, calculates the local time of the city based on the date and time counted by the timekeeping circuit 46, and outputs a control signal to the drive circuit 50. Then, the hour and minute hands 12 and 13 indicate the local time (step S513). When the date changes, the CPU 41 rotates the date wheel 15 to set the correct date, and in this state, the mode pointer 14 is set to the position of the sign "N". Then, the process of the CPU 41 returns to step S508.

When it is determined in the determination process of step S508 that the pull-out operation or the push-back operation of the crown C1 is detected (“YES” in step S508), the CPU 41 has one crown C1 before the detected operation. It is determined whether or not the drawer state is in the stage (step S521). When it is determined that the state has been pulled out in one step (“YES” in step S521), the CPU 41 is currently instructed by the second hand 11, the local time indicator, and the minute hand 12 and the hour hand 13. The local time setting related to the time is confirmed as the local time setting related to the world clock, and is retained and stored in the clock setting information 43a (step S522). Then, the process of the CPU 41 shifts to step S524.

If it is determined that the crown C1 was not in the one-step drawer state, that is, the crown C1 was in the two-step drawer state (“NO” in step S521), the CPU 41 is currently instructed by the second hand 11. The local time sign indicated by the minute hand 12 and the local time set indicated by the hour hand 13 is determined as the local time setting related to the basic clock, and is stored and stored in the clock setting information 43a (step S523). Then, the process of the CPU 41 shifts to step S524.

When the process of steps S520, S522, and S523 shifts to the process of step S524, the CPU 41 determines whether or not the crown C1 is not pulled out after the detected crown C1 is operated (the crown C1 is not pulled out). Step S524). If it is determined that the device has not been pulled out (“YES” in step S524), the CPU 41 ends the local time manual setting process. If it is determined that the battery has been pulled out (“NO” in step S524), the process of the CPU 41 returns to step S501.

FIG. 6 is a flowchart showing a control procedure by the CPU 41 of the time difference manual setting process called in step S520 of the local time manual setting process.

When the time difference manual setting process is called, the CPU 41 determines whether or not the current position information is held as the clock setting information related to the clock function (basic clock / world clock) during the setting display (step). S561). When it is determined that the current position information is held (“YES” in step S561), the CPU 41 erases the current position information and outputs a control signal to the drive circuit 50. The mode pointer 14 is instructed to indicate the sign “N” in the small window 3b (step S562). Then, the process of the CPU 41 proceeds to step S563.

If it is determined that the current position information is not held (“NO” in step S561), the processing of the CPU 41 proceeds to step S563.

When the process of steps S561 and S562 shifts to the process of step S563, the CPU 41 outputs a control signal to the drive circuit 50 and causes the second hand 11 to indicate an exception sign (step S563). The CPU 41 determines whether or not the pull-out operation or the push-back operation of the crown C1 is detected (step S564).

If it is determined that the pull-out operation or push-back operation of the crown C1 has not been detected (“NO” in step S564), has the CPU 41 detected the rotation operation of the crown C1 (second input operation)? Whether or not it is determined (step S565). If it is determined that it has not been detected (“NO” in step S565), the processing of the CPU 41 returns to step S564. If it is determined to be detected (“YES” in step S565), the CPU 41 sets the local time to 15 minutes according to the rotation direction of the crown C1 for the clock function (world clock / basic clock) currently set. It is increased or decreased, a control signal is output to the drive circuit 50, the hour and minute hands 12 and 13 are fast-forwarded, and the local time displayed by the hour and minute hands 12 and 13 is changed by 15 minutes (step S566). When the date and time change with the change of the local time, the CPU 41 rotates the date wheel 15 to change the date, and in this state, causes the mode pointer 14 to indicate the sign "N". Then, the process of the CPU 41 returns to step S564.

If it is determined in the determination process of step S564 that the pull-out or push-back operation of the crown C1 is detected (“YES” in step S564), the CPU 41 performs the crown C1 before the detected operation. It is determined whether or not is in the state of being pulled out one step (step S571). If it is determined that the state has been pulled out one step (“YES” in step S571), the CPU 41 sets the date and time indicated by the hour and minute hands 12, 13 and the day wheel 15 to the current local time at the world clock position. The time is set, the time difference information is acquired from the difference from the date and time counted by the timekeeping circuit 46, the time zone is determined, and the time zone is stored and held in the clock setting information 43a as the local time setting information related to the world clock (step S572). Then, the CPU 41 ends the time difference manual setting process and returns the process to the local time manual setting process.

If it is determined that the state was not pulled out in one step, that is, the state was pulled out in two steps (“NO” in step S571), the CPU 41 is instructed by the hour / minute hands 12, 13 and the date wheel 15. The set date and time is set as the current local time at the home position, the time difference information is acquired from the difference from the date and time counted by the timekeeping circuit 46 to determine the time zone, and the clock setting information is used as the local time setting information related to the basic clock. It is stored and held in 43a (step S573). Then, the CPU 41 ends the time difference manual setting process and returns the process to the local time manual setting process.

FIG. 7 is a flowchart showing a control procedure by the CPU 41 of the clock setting replacement process executed by the electronic clock 1 of the present embodiment.
This clock setting replacement process is started according to a predetermined input operation, for example, a state in which the user continuously presses the push button switch B4 for 3 seconds or longer.

When the clock setting replacement process is started, the CPU 41 replaces the clock setting related to the basic clock and the clock setting related to the world clock in the clock setting information 43a (step S701). The CPU 41 calculates the local time of the home position according to the local time setting of the home position determined by the clock setting related to the basic clock, outputs a control signal to the drive circuit 50, and displays the time by the hour and minute hands 12 and 13 in the local time. It is changed from time to time (step S702).

The CPU 41 determines whether or not there is a local time sign in the urban area corresponding to the time zone of the replaced home position (step S703). If it is determined to be present (“YES” in step S703), the CPU 41 outputs a control signal to the drive circuit 50 and causes the second hand 11 to indicate the local time sign (step S704). Then, the process of the CPU 41 proceeds to step S706. If it is determined that there is no local time sign in the urban area corresponding to the time zone of the replaced home position (“NO” in step S703), the CPU 41 outputs a control signal to the drive circuit 50 and the second hand. 11 is instructed to indicate an exception sign (step S705). Then, the process of the CPU 41 proceeds to step S706.

When the process proceeds to step S706, the CPU 41 determines whether or not the current position information is included in the clock setting information related to the replaced basic clock (step S706). If it is determined that the signal is included (“YES” in step S706), the CPU 41 outputs a control signal to the drive circuit 50 and causes the mode pointer 14 to indicate the sign “P” (step S707). Then, the process of the CPU 41 proceeds to step S709. If it is determined that it is not included (“NO” in step S706), the CPU 41 outputs a control signal to the drive circuit 50 and causes the mode pointer 14 to indicate the sign “N” in the small window 3b (“N” in the small window 3b. Step S708). Then, the process of the CPU 41 proceeds to step S709.

When the process shifts to the process of step S709, the CPU 41 maintains the display and waits for a predetermined time, for example, 2 seconds (step S709). Then, the CPU 41 ends the clock setting replacement process.

8 and 9 are diagrams showing a display example of position setting by the electronic clock 1 of the present embodiment.
When the time zone is set to UTC + 9 hours such as Jayapura in Tokyo or Indonesia based on the city time difference information 42b shown in Fig. 3 (a) by user operation or radio reception of the positioning satellite at 10:10 UTC time. Local time is 19:10, and as shown in FIG. 8A, the hour and minute hands 12 and 13 indicate 7:10. Further, the mode pointer 14 indicates the sign "P", and the second hand 11 indicates the local time sign "TYO" corresponding to UTC + 9.

After the updated city time difference information 42c and the updated data of the time difference map 491c shown in FIG. 3 (b) were acquired, the current position was identified as Tokyo by receiving radio waves from the positioning satellite at 10:10 UTC time. If so, the basic clock display calculates the local time of 18:10 based on the updated city time difference information 42c and the updated time difference map 491c, and as shown in FIG. 8 (b), the hour and minute hands. 12 and 13 indicate 6:10. At this time, the mode pointer 14 is controlled to indicate the sign "P", and the second hand 11 is controlled to indicate the local time sign "HKG" set as UTC + 8 from the beginning.

On the other hand, if the current position is identified as Jayapura in Indonesia by receiving radio waves from the positioning satellite at 10:10 UTC time after the updated data of the updated city time difference information 42c and the time difference map 491c are acquired, it is basic. The clock display is calculated at 19:10 local time, and as shown in FIG. 8C, the hour and minute hands 12 and 13 indicate 7:10. At this time, the mode pointer 14 indicates the sign “P”, and the second hand 11 indicates the exception sign, indicating that the time difference is UTC + 9, which does not exist on the bezel 4.

When the home position is set in Tokyo by user operation at 10:10 UTC time after the updated city time difference information 42c is acquired, the second hand 11 is set as shown in FIG. 9 (a) with this setting. The local time sign "TYO" is instructed, and the mode guideline 14 indicates the sign "N". At this time, the time displayed by the hour and minute hands 12 and 13 is 6:10 corresponding to 18:10, which is UTC + 8 hours.

In this situation, if the user wants to set the time display of UTC + 9 hours such as Jayapura in Indonesia, the user sets the display time to UTC + 9 hours at 19:10 as shown in FIG. 9B based on the time difference manual setting process. It can be set to 7:10 corresponding to. At this time, the designated position of the mode pointer 14 is the sign “N”, and the local time sign indicated by the second hand 11 is an exception sign.

As described above, the electronic clock 1 of the present embodiment has a bezel 4 provided with a plurality of local time signs indicating positions in various parts of the world, a second hand 11 that moves relative to the bezel 4, a local time sign, and the local time. The bezel includes a ROM 42 that stores the city time difference information 42b associated with the information related to the time zone to which the position indicated by the time indicator belongs, and a CPU 41 that controls the operation of moving the second hand 11 relative to the bezel 4. 4 is provided with an exception sign indicating that it does not correspond to any of the time zones associated with the local time sign by being instructed by the second hand 11 (predetermined positional relationship), and the CPU 41 displays it. When displaying the time zone set for the target date and time, if there is no local time sign associated with the set time zone, the second hand 11 is instructed to indicate an exception sign.
This eliminates the need to pack signs for all time zones and arrange signs at intervals according to the time difference, especially for signs such as urban areas that are expected to be used infrequently for setting. Since the space can be omitted, the time zone setting display can be performed more flexibly and appropriately.

Further, the ROM 42 can store the updated city time difference information 42c that updates the city time difference information 42b. As a result, even if the time zone to which the urban area set on the bezel belongs is changed, it is possible to display the appropriate local time with normal operation without replacing the entire clock. In addition, when the time zone is changed in this way and there is no urban area corresponding to the time zone to be set, or when a new time zone is established, there is no position to indicate the time zone or the user is misunderstood. It is possible to prevent the occurrence of such problems.

Further, the CPU 41 is not used for the display related to the time zone in which the local time indicator whose associated time zone is changed from the initial setting is set.
This does not confuse the user as to when the time zone corresponding to the indicated local time indicator is.

Further, the communication unit 48 for acquiring the updated city time difference information 42c to be updated and stored from an external device is provided. This makes it possible to easily change the internal settings of the electronic clock, particularly the setting data of the time zone that is often changed, so that the correct local time can be displayed more flexibly and appropriately.

Further, since the exception sign is indicated by a predetermined sign, it is easily indicated that the user is in an area other than the time zone corresponding to the city indicated by the local time sign.

Further, the operation receiving unit 47 for receiving an input operation is provided, and the CPU 41 sets and sets a time zone for the date and time to be displayed based on a predetermined input operation for the push button switches B1 to B4 and the crown C1. If the time zone does not correspond to any of the local time signs, the second hand 11 is instructed to indicate an exception sign, and the time zone set is displayed.
As a result, when setting the local time to be displayed, the time zone of the local time can be displayed appropriately and flexibly.

Further, a timekeeping circuit 46 for counting a reference date and time, here, a UTC date and time, is provided, and the CPU 41 sets a time zone based on the difference between the current date and time received by a predetermined input operation and the reference date and time. I do. In this way, not only the time zone can be set by selecting the city, but also the local time may be set according to the time difference by inputting a specific date and time. Even in this case, the set time zone can be displayed in the same way, and if this time zone does not correspond to the city provided on the bezel 4, or if it was originally supported but changed and no longer corresponds. Can be flexibly dealt with.

Further, the CPU 41 causes the second hand 11 to indicate a predetermined local time indicator by the rotation operation of the crown C1 (first input operation), and corresponds to the local time indicator indicated by the position of the changed second hand 11. The date and time in the attached time zone is displayed as the date and time to be displayed by the hour and minute hands 12 and 13, and after the push button switch B3 is continuously pressed for 1 second or longer, the crown C1 is further rotated (second). By the input operation), the date and time displayed by the hour and minute hands 12 and 13 are changed, and the time zone is set based on the difference between the changed date and time and the reference date and time counted by the timekeeping circuit 46. Therefore, when setting a time zone other than the time zone corresponding to the city where the local time sign is provided on the bezel 4, or when the user thinks that it corresponds, the time zone of the city area indicated by the local time sign is changed. Even if it has been set, the time zone can be set appropriately, and the time zone set according to this setting can be displayed without difficulty.

Further, a satellite radio wave reception processing unit 49 that acquires information related to the current position and a storage unit 49c that stores the correspondence between the current position and the time zone acquired by the satellite radio wave reception processing unit 49 as a time difference map 491c. The control unit includes a control unit 49b of the satellite radio wave reception processing unit 49, and the control unit 49b is a time zone to which the current position acquired by the satellite radio wave reception processing unit 49 based on the time difference map 491c belongs. To identify. In this way, not only when the user manually sets the time zone, but also when the current position is acquired based on the positioning data, the time zone is appropriately set according to the current position, and the set time zone is set. Can be displayed flexibly and appropriately.

Further, the storage unit 49c can update and store this correspondence. Therefore, similar to the above-mentioned updated city time difference information 42c, it is possible to flexibly respond to changes in time zone settings in various parts of the world, and to flexibly and appropriately display the time zone correctly determined in this way. Can be done.

Further, the satellite radio wave reception processing unit 49 acquires information related to the current position, and includes a mode guideline 14 indicating whether or not the time zone corresponding to the current position is used for setting the date and time to be displayed.
This makes it possible to easily determine whether the time zone is set manually by the user or automatically based on the positioning result.

Further, the satellite radio wave reception processing unit 49 operates as a positioning operation unit that receives radio waves from the positioning satellite and performs positioning. Therefore, it is possible to easily and surely acquire the information of the current position in various parts of the world. Further, based on the latitude / longitude information, the time zone can be surely set even in an area different from the urban area related to the local time sign provided on the bezel 4. Further, the user can determine whether or not the appropriate time zone is automatically set in this way by combining the local time sign instruction by the second hand 11 and the indications "P" and "N" by the mode guideline 14. Can be determined, and it is possible to set so that the desired local time can be displayed more easily and appropriately while reducing the time and effort of the user related to the time zone setting.

Further, the indicator unit is a second hand 11 provided so as to be rotatable, and the CPU 41 rotates the second hand 11 to indicate one local time sign provided on the bezel 4 by the second hand 11, so that the timepiece is originally It is possible to expand the range of design in a wider variety while making it possible to easily set the time zone by using the operation of.

Further, the setting display method in the electronic clock 1 according to the embodiment of the present invention is an exception instruction position (exception) indicating that the setting display method does not correspond to any of the time zones associated with the local time indicator by being instructed by the second hand 11. When displaying the exception position setting step for setting the sign) to the bezel 4 and the time zone set for the date and time to be displayed, the second hand 11 and the bezel 4 are moved relative to each other to set the time zone. When there is no associated local time sign, the setting display step of causing the second hand 11 to indicate the exception instruction position is included. In this way, it is possible to more flexibly and appropriately display the time zone setting by the exception instruction position that collectively shows the parts that cannot be shown by the normal position sign.

[Second Embodiment]
Next, the electronic clock of the second embodiment will be described.
FIG. 10 is a front view showing the appearance of the electronic clock 1a of the present embodiment.

The electronic clock 1a of the second embodiment is provided with an opening 3c in the dial 3 of the electronic clock 1 of the first embodiment, and is rotatably provided on the back surface side of the dial 3 which is a fixed plate. The local time sign provided on the surface of the display panel 16 can be selectively exposed. The opening 3a is provided closer to the rotation axis of the pointers 11 to 13 and 15 than the electronic clock 1 of the first embodiment, and is formed smaller so that the date wheel 15 is not exposed from the opening 3c. Further, instead of the signs "Y" and "N" on the dial 3, the signs "TIME" and "T + P" are provided. Further, the bezel 4 is replaced with the bezel 4a. Other configurations are the same for the electronic clock 1 and the electronic clock 1a, and the same reference numerals are used for the same components, and the description thereof will be omitted.

The opening 3c exposes an angular range wider than the angular interval of the local time sign provided on the position display panel 16, whereby a plurality of local time signs are simultaneously exposed from the opening 3c. On the rotation axis side of the pointers 11 to 13 and the like from the opening 3c, there is an instruction part 3d for instructing (exposing at a predetermined position) one local time sign, here a horizontal triangle whose inside is filled. When one local time sign is provided at a position corresponding to this indicator, about two local time signs are exposed above and below (front and back) from the opening 3c.

The signs "TIME" and "T + P" indicate that when the satellite radio wave reception processing unit 49 receives the radio wave from the positioning satellite, only the date and time information is acquired, and both the date and time and the current position are acquired. show.

The bezel 4a is provided with a time difference sign indicating a time difference (+14 to -12) instead of the local time sign.

FIG. 11 is a front view of the position display panel 16.
Here, as with the electronic clock 1 of the first embodiment, the local time sign is a position sign indicating 28 urban areas, a reference sign indicating UTC, and a total of 30 exception signs in a range of 120 degrees at 4 degree intervals. It is arranged at equal intervals within, but it is not limited to this, and local time signs indicating more time zones (urban areas) may be provided.

Further, on the position display board 16, signs "YES" and "NO" are provided apart from the local time sign. These two signs indicate the success or failure of the acquisition of the position information by the satellite radio wave reception processing unit 49.
With these configurations, in the electronic clock 1a of the present embodiment, the position display panel 16 constitutes a sign unit, and the dial 3 (indicator unit 3d) constitutes an indicator unit.

FIG. 12 is a block diagram showing a functional configuration of the electronic clock 1a of the present embodiment.
This functional configuration is the same as that of the electronic clock 1 of the first embodiment except that the position display panel 16, the stepping motor 56, the train wheel mechanism 66, and the like are added, and the same components are the same. The explanation is omitted.

For example, the position display panel 16 is rotated by 4 degrees by a rotation operation of 60 steps, and the local time sign exposed from the opening 3a changes by one city. That is, the train wheel mechanism 66 rotates the position display panel 16 by 1/15 degree according to the step rotation operation (180 degree rotation) of the stepping motor 56.

FIG. 13 is a flowchart showing a control procedure by the CPU 41 of the current position acquisition setting process executed by the electronic clock 1a of the present embodiment.
This current position acquisition setting process is the same as the current position acquisition setting process of the first embodiment except that the processes of steps S605, S608, and S611 are replaced with the processes of steps S605a, S608a, and S6011a, respectively. Therefore, the same processing contents are designated by the same reference numerals and detailed description thereof will be omitted.

If it is determined in the determination process of step S604 that the clock setting information has been normally acquired (“YES” in step S604), the CPU 41 outputs a control signal to the drive circuit 50 to display the position display panel 16. The sign "YES" is displayed in accordance with the position of the instruction unit 3d, the second hand 11 is instructed to indicate "T + P", and the mode pointer 14 is instructed to indicate "P" (step S605a). Then, the process of the CPU 41 shifts to step S606.

If it is determined in the determination process of step S604 that the clock setting information is not normally acquired (“NO” in step S604), a control signal is output to the drive circuit 50 to output the position display panel 16. The sign "NO" is displayed in accordance with the position of the indicator 3d (step S611a). At this time, if the clock setting information is not acquired but only the date and time information is acquired, the CPU 41 causes the second hand 11 to indicate the sign "TIME". If the date and time information is not acquired, the CPU 41 moves the second hand 11 to a reference position, for example, a position of 0 seconds. Then, the process of the CPU 41 proceeds to step S612.

When the local time indicator corresponding to the local time setting information is identified in the process of step S607, the CPU 41 outputs a control signal to the drive circuit 50 and sets the time difference defined in the local time setting information to the second hand 11. The position display board 16 is rotated so that the designated local time sign matches the position of the indicating unit 3d (step S608a). Then, the process of the CPU 41 proceeds to step S609.

If it is determined in the determination process of step S501 that the crown C1 is not in the one-step withdrawal state (it is in the two-step withdrawal state) (“NO” in step S501), the CPU 41 is controlled by the drive circuit 50. A signal is output, the local time is displayed by the hour and minute hands 12 and 13 based on the clock setting information related to the basic clock, and the position display panel 16 is rotated so that the local time indicator corresponding to the time zone matches the indicator 3d. It is operated, and the time difference is indicated by the second hand 11 (step S504a). Then, the process of the CPU 41 shifts to step S505.

Further, when the process of step S511 or step S512 shifts to the process of step S513a, the CPU 41 outputs a control signal to the drive circuit 50, and the detected crown C1 is located in the adjacent region in a direction corresponding to the rotational operation direction. The position display panel 16 is rotated so that the hour sign matches the indicator 3d. Further, the CPU 41 causes the second hand 11 to indicate the time difference corresponding to the local time indicator that outputs a control signal to the drive circuit 50 and matches the position of the indicator 3d, and the local time reflecting the time difference is indicated by the hour and minute hands 12 and 13. Display (step S513a). Then, the process of the CPU 41 returns to step S508.

FIG. 15 is a flowchart showing a control procedure by the CPU 41 of the time difference manual setting process called in the local time manual setting process of the electronic clock 1a of the present embodiment.
In this time difference manual setting process, the process of steps S563 and S566 is replaced with the process of steps S563a and S566, respectively, as compared with the time difference manual setting process called by the local time manual setting process of the electronic clock 1 of the first embodiment. Except for the above points, they are the same, and the same processing contents are designated by the same reference numerals and the description thereof will be omitted.

When the process of step S561 or step S562 shifts to the process of step S563a, the CPU 41 outputs a control signal to the drive circuit 50 to rotate the position display panel 16 to align the exception sign with the position of the indicator 3d (step). S563a). Then, the process of the CPU 41 shifts to step S564.

When it is determined that the rotation operation of the crown C1 is detected in the determination process of step S565 (“YES” in step S565), the CPU 41 detects the rotation of the crown C1 in the local time. Is changed for 15 minutes, and the time difference is changed accordingly for 15 minutes. Then, the CPU 41 outputs a control signal to the drive circuit 50, causes the hour and minute hands 12 and 13 to display the changed local time, and causes the second hand 11 to display the changed time difference (step S566a). Then, the process of the CPU 41 returns to step S564.
