Description

  The present invention relates to an electronic timepiece and a pointer control method.

  In an analog electronic timepiece, the user needs to read the scale indicated by the hands. Therefore, it is necessary to limit the numerical value range of the scale (hereinafter referred to as “instructible range”) to such an extent that it is not difficult to read the scale indicated by the pointer. Thereby, the instructable range may not include a part of the measurement value. Therefore, there is an electronic timepiece that performs a predetermined notification means when the measured value exceeds the instructable range. For example, Patent Document 1 discloses an electronic timepiece having a pointer provided so as to be capable of rotating only in a partial angular range of a circumference. This electronic timepiece controls the pointer so as to reciprocate by fast-forwarding from an outer position to an inner position within an angular range in which the pointer can rotate as predetermined notification means.

JP 2017-58265 A

  However, in the above-described conventional electronic timepiece, the user can grasp that the measured value exceeds the instructable range, but grasps how much the measured value exceeds the instructable range. It is difficult.

  One of the problems to be solved by the present invention is to enable a user to grasp a measured value that exceeds the instructable range even if the numerical value to be indicated by the hands exceeds the instructable range in an analog timepiece. To do.

  An electronic timepiece according to a preferred aspect (first aspect) of the present invention includes a first hand, a first scale indicating a numerical value within a predetermined range indicated by the first hand, a second hand, and the second hand. A second scale including a numerical value exceeding the predetermined range to be instructed, wherein the first pointer indicates a change amount per unit time of altitude, and the second pointer indicates a maximum value of the change amount in a predetermined period; Or specify the minimum value.

  In the above aspect, when the change amount per unit time of the altitude exceeds a numerical value within a predetermined range that can be indicated by the first pointer, the second pointer is set to the maximum value or the minimum value of the change amount during the predetermined period. In response, the second scale is indicated. Therefore, the user can grasp the maximum value or the minimum value of the change amount exceeding the predetermined range in the predetermined period by confirming the numerical value indicated by the second pointer.

  In a preferred example of the first aspect (second aspect), the storage device stores the amount of change in the predetermined period for each unit time, and the second pointer is in the predetermined period stored in the storage unit. Specify the maximum or minimum change.

In the above aspect, the predetermined period may be, for example, from one minute before the current time to the current time. In this case, the start of the predetermined period changes every moment. When the start of the predetermined period fluctuates, the first time when the amount of change becomes the maximum value or the minimum value in the predetermined period before the fluctuation may not be included in the predetermined period after the fluctuation. For simplification of description, an example in which the maximum value of the change amount is displayed will be described. If the storage unit stores only the maximum value of the change amount in the predetermined period before the change, the maximum value of the change amount in the predetermined period after the change, that is, the next largest change amount after the change amount at the first time is calculated. Can not do it.
However, in the above aspect, it is possible to calculate the maximum value or the minimum value of the change amount in the predetermined period after the change from the change amount for each unit time stored in the storage unit. Therefore, according to the above aspect, even when the start of the predetermined period varies, the user can grasp the maximum value or the minimum value of the change amount exceeding the predetermined range in the predetermined period.

  In a preferred example of the first aspect or the second aspect (third aspect), a third pointer is provided, the second pointer indicates a maximum value of the change amount, and the third pointer indicates a minimum value of the change amount. Indicate the value.

  According to the above aspect, the user can grasp the maximum value of the change amount and the minimum value of the change amount at a time.

  In a preferred example of the first aspect or the second aspect (fourth aspect), a fourth pointer, a fifth pointer, a third scale indicated by the fourth pointer and the fifth pointer are provided, and the second pointer is One of the maximum value and the minimum value of the change amount is indicated, and the other value of the maximum value or the minimum value of the change amount is indicated by the fourth pointer and the fifth pointer.

  According to the above aspect, the user can grasp the maximum value of the change amount and the minimum value of the change amount at a time. Furthermore, when trying to display a value of a plurality of digits with one pointer, a large scale in which numbers indicating the values of the plurality of digits are arranged is necessary. For example, if a two-digit value is displayed, a scale indicating “0” to “99” is required. Since a large scale occupies a large area of the display unit, it is preferable that the scale is small. According to the above-described aspect, since the fourth hand and the fifth hand indicate the value of each digit of the other value of the maximum value or the minimum value, the scale indicating “0” to “9” is used. In other words, the scale size can be reduced as compared with the case where “0” to “99” are indicated. Therefore, in the above-described aspect, it is possible to display a plurality of digits of the other value of the maximum value or the minimum value while reducing the size of the scale.

  In a preferred example (fifth aspect) of the first to fourth aspects, the apparatus includes an atmospheric pressure sensor and a calculation unit that calculates the amount of change based on the atmospheric pressure measured by the atmospheric pressure sensor.

In the above aspect, when calculating the change amount per unit time of the altitude from the atmospheric pressure, the atmospheric pressure at the first time and the atmospheric pressure at the second time measured by the atmospheric pressure sensor are converted into a conversion formula for converting the atmospheric pressure into the altitude. Substituting each one, the altitude at the first time and the altitude at the second time are calculated. Then, based on a value obtained by subtracting the altitude at the first time from the altitude at the second time and a value obtained by subtracting the first time from the second time, a change amount of the altitude per unit time is calculated. Thus, in the fifth aspect, the atmospheric pressure sensor may measure the atmospheric pressure at the first time and the atmospheric pressure at the second time.
On the other hand, there are the following two methods for calculating the amount of change per unit time of altitude. In the first method, the electronic timepiece calculates a first position and a second position from a satellite signal obtained from a position information satellite such as a GPS (Global Positioning System) satellite, and calculates the heights of the calculated first position and second position. The distance in the vertical direction is calculated, and the amount of change in altitude per unit time is calculated based on the time at the first position and the time at the second position, and the calculated distance in the height direction. In the second method, the electronic timepiece extracts the acceleration in the height direction from the acceleration in the triaxial direction obtained from the triaxial acceleration sensor, and integrates the extracted acceleration to thereby change the altitude per unit time. Is calculated.
However, in the first method, in order to calculate the position, it is necessary to receive satellite signals from at least four satellites and obtain values of four variables such as latitude, longitude, altitude, and time. More processing load is required than the method. In the second method, since the acceleration must be continuously measured, the processing load is higher than that in the method according to the fifth aspect. As described above, according to the fifth aspect, it is possible to reduce the processing load on the electronic timepiece as compared with the first method and the second method.

  An electronic timepiece according to a preferred aspect of the present invention (sixth aspect) includes a first hand, a first scale indicating a numerical value within a predetermined range indicated by the first hand, a second hand, and the second hand. A pointer control method for controlling a pointer of an electronic timepiece provided with a second scale indicating a numerical value exceeding the predetermined range to be indicated, wherein the first pointer is per unit time of the current altitude of the electronic timepiece. And the second indicator indicates the maximum value or the minimum value of the change amount in a predetermined period.

  When the amount of change per unit time of the altitude exceeds a numerical value within a predetermined range that can be indicated by the first pointer, the second pointer changes the second value according to the maximum value or the minimum value of the amount of change during the predetermined period. Instruct the scale. Therefore, the user can grasp the maximum value or the minimum value of the change amount exceeding the predetermined range in the predetermined period by confirming the numerical value indicated by the second pointer.

The frequency of the clock signal is divided, and the clock signal having a frequency of 1 Hz is input to the control unit 6. The GPS receiver 2 receives a satellite signal from a GPS satellite that is one of position information satellites. The triaxial magnetic sensor 3 measures magnetic north. The atmospheric pressure sensor 4 measures the atmospheric pressure around the electronic timepiece W.

  The storage unit 5 is a readable / writable nonvolatile recording medium. The storage unit 5 is, for example, a flash memory. The storage unit 5 is not limited to the flash memory and can be changed as appropriate. The storage unit 5 stores, for example, a program executed by the control unit 6.

  The control unit 6 is, for example, a computer such as a CPU (Central Processing Unit). The control unit 6 controls the entire electronic timepiece W. The configuration of the control unit 6 will be described with reference to FIG.

A. 2. Configuration of Control Unit 6 According to First Embodiment FIG. 8 shows a configuration diagram of the control unit 6. The control unit 6 reads and executes the program stored in the storage unit 5, thereby displaying the display control unit 61, the elevation calculation unit 62 (an example of “calculation unit”), the atmospheric pressure tendency calculation unit 63, and the azimuth calculation. The unit 65 is realized. Hereinafter, the configuration of the control unit 6 will be described for each of the elevation display mode, the compass mode, and the atmospheric pressure display mode.

A. 2.1. Configuration of the Control Unit 6 in the Elevation Level Display Mode In the elevation level display mode, the elevation level calculation unit 62 acquires the atmospheric pressure measured by the atmospheric pressure sensor 4 every second in order to display the elevation level. The elevation calculation unit 62 calculates the altitude based on the acquired atmospheric pressure according to the equation (1).

  ALT = 153.8 × (t0 + 273.2) × (1- (acquired atmospheric pressure / P0) ^ 0.1902) + manual offset value (1)

  t0 is a reference temperature, which is 15 degrees. P0 is a reference atmospheric pressure and is 101.25 hPa. ALT indicates altitude. The calculated altitude unit is m (meters). The manual offset value is a value that can be set by the user. The reason why the manual offset value is provided is that the accuracy of the calculated altitude may be deteriorated because only the first term on the right side of the equation (1) becomes a high pressure or a low pressure depending on the season or climate. Therefore, before setting the coordinates of the destination Dst, the electronic timepiece W calculates the altitude at a position where the actual altitude is known by setting the manual offset value of the equation (1) to 0. Thereafter, the user sets a value obtained by subtracting the calculated altitude from the actual altitude as the manual offset value. As a result, the electronic timepiece W can obtain a more accurate altitude as compared with the case where the manual offset value is zero.

  The elevation calculation unit 62 stores the calculated altitude in the storage unit 5. Furthermore, the elevation calculation unit 62 calculates a value obtained by subtracting the one-second previous altitude stored in the storage unit 5 from the calculated altitude. The unit of elevation is m / second. The elevation calculation unit 62 outputs the calculated elevation to the display control unit 61. The display control unit 61 controls the small second hand 41 so as to display the acquired elevation degree.

Further, the display control unit 61 controls the center pointer 13 so as to display the maximum value of the elevation in the display period. For example, there are the following two methods for displaying the maximum value of the elevation.
In the first method, the display control unit 61 compares the altitude calculated by the elevation calculation unit 62 with the altitude indicated by the center pointer 13 during the display period. If the altitude calculated by the elevation calculation unit 62 is higher, the display control unit 61 controls the center pointer 13 so that the center pointer 13 indicates the altitude calculated by the elevation calculation unit 62.

  In the second method, the storage unit 5 stores the elevation in the display period for each unit time. The display control unit 61 refers to the storage unit 5 and calculates the maximum value of the lift from the stored lift. Then, the display control unit 61 controls the center pointer 13 so that the center pointer 13 instructs the calculated maximum degree of elevation. Below, the case where the display method of the maximum value of elevation is the second method will be described as an example.

A. 2.2. Configuration of Control Unit 6 in Compass Mode In the compass mode, the azimuth calculation unit 65 acquires the azimuth of magnetic north measured by the three-axis magnetic sensor 3. The bearing calculation unit 65 calculates the bearing of true north based on the acquired magnetic north. The direction calculation unit 65 outputs the calculated true north direction to the display control unit 61. The display control unit 61 controls the center pointer 13 so that the center pointer 13 faces the acquired true north direction.

A. 2.3. Configuration of the control unit 6 in the atmospheric pressure display mode In the atmospheric pressure display mode, the atmospheric pressure tendency calculation unit 63 acquires the atmospheric pressure measured by the atmospheric pressure sensor 4 every second. The atmospheric pressure tendency calculation unit 63 stores the acquired atmospheric pressure in the storage unit 5. Further, the atmospheric pressure tendency calculation unit 63 outputs the acquired atmospheric pressure to the display control unit 61. Furthermore, the atmospheric pressure tendency calculation unit 63 calculates a value obtained by subtracting the atmospheric pressure one second before stored in the storage unit 5 from the acquired atmospheric pressure. The atmospheric pressure tendency calculation unit 63 calculates that the atmospheric pressure tendency is positive if the calculated value is positive, and calculates that the atmospheric pressure tendency is negative if the calculated value is negative. The atmospheric pressure trend calculation unit 63 outputs the calculated atmospheric pressure trend to the display control unit 61.

  The display control unit 61 controls the numerical display short hand 32, the numerical display long hand 33, and the center pointer 13 so as to indicate the acquired atmospheric pressure. Further, the display control unit 61 controls the small second hand 41 so as to indicate the calculated atmospheric pressure tendency.

A. 3. Flowchart of each operation mode Each of the elevation display mode and the atmospheric pressure display mode will be described using specific flowcharts.

A. 3.1. FIG. 9 shows a flowchart of the elevation display mode. When the operation button A is pressed several times by the user and the mode pointer 21 indicates the character string 23b, the electronic timepiece W sets the operation mode to the elevation display mode. In the elevation display mode, the control unit 6 controls the hour hand 11 and the minute hand 12 to display the current time, controls the center pointer 13 to stop at the 12 o'clock position, and instructs “0”. The numerical display short hand 32 and the numerical display long hand 33 are controlled.

  When the operation mode is set to the elevation display mode, the control unit 6 detects a pressing operation of the operation button B for a predetermined time (for example, 3 seconds) or more (step S1). The predetermined time is not limited to 3 seconds and can be changed as appropriate. When the pressing operation for a predetermined time or longer is detected, the lift calculation unit 62 starts calculating the lift. Next, the elevation calculation unit 62 acquires the atmospheric pressure measured by the atmospheric pressure sensor 4, and calculates the elevation according to the equation (1) (step S2). Then, the display control unit 61 controls the small second hand 41 so as to indicate the calculated elevation degree (step S3). Further, the display control unit 61 refers to the storage unit 5 and calculates the maximum value of the elevation in the display period (step S4). And the display control part 61 controls the center pointer | guide 13 so that the calculated maximum value of the raising / lowering degree may be instruct | indicated (step S5).

  Next, the control unit 6 determines whether one minute has elapsed since the operation mode was set to the elevation display mode or whether a pressing operation of the operation button B was detected (step S6). If one minute has not elapsed and the pressing operation of the operation button B has not been detected (step S6: No), the elevation calculation unit 62 performs the process of step S2 one second after the previous execution. Run. On the other hand, when one minute has passed or the pressing operation of the operation button B is detected (step S6: Yes), the control unit 6 ends the series of processes.

A. 3.2. FIG. 10 is a flowchart of the atmospheric pressure display mode. When the user presses the operation button A several times and the mode pointer 21 indicates the character string 23d, the electronic timepiece W sets the operation mode to the atmospheric pressure display mode. When the operation mode is set to the atmospheric pressure display mode, the control unit 6 detects a pressing operation of the operation button B for a predetermined time or longer (step S11). When a pressing operation for a predetermined time or longer is detected, the atmospheric pressure tendency calculation unit 63 starts calculating atmospheric pressure and atmospheric pressure tendency. Next, the atmospheric pressure tendency calculation unit 63 calculates the atmospheric pressure and the atmospheric pressure tendency (step S12). Then, the display control unit 61 controls the numerical display short hand 32, the numerical display long hand 33, and the center pointer 13 so as to indicate the calculated atmospheric pressure (step S13). Further, the display control unit 61 controls the small second hand 41 so as to indicate the calculated atmospheric pressure tendency (step S14).

  Then, the control unit 6 determines whether one minute has elapsed since the operation mode was set to the atmospheric pressure display mode, or whether the pressing operation of the operation button B has been detected (step S15). When one minute has not elapsed and the pressing operation of the operation button B has not been detected (step S15: No), the atmospheric pressure tendency calculation unit 63 performs the process of step S12 one second after the previous execution. Run. On the other hand, when one minute has elapsed or when the pressing operation of the operation button B is detected (step S15: Yes), the control unit 6 ends the series of processes.

A. 4). Effects of First Embodiment As described above, the display unit 10 is provided with the scales 42p, the scales 42m, and the scales 42z corresponding to the small second hand numerical value range. Furthermore, the display unit 10 is provided with a scale 14c corresponding to the center pointer numerical value range. The small second hand 41 indicates one of the scale 42p, the scale 42m, and the scale 42z according to the current elevation degree of the electronic timepiece W. The center pointer 13 indicates the scale 14c according to the maximum or minimum value of the elevation during the display period.
Since the small second hand numerical range is a real number of −5 or more and 5 or less, when the electronic timepiece W suddenly rises or falls, the ascending / descending degree exceeds the small second hand numerical range. The reason why the ascending / descending degree exceeds the small second hand numerical value range is that the ascending / descending degree is displayed on a part of the display unit 10, which is the 10 o'clock side information display unit 40. This is because it is difficult to make the numerical range.
Therefore, in the first embodiment, since the center pointer numerical value range includes a numerical value exceeding the small second hand numerical value range, the center pointer 13 instructs the maximum value of the elevation in the display period.
Thereby, the user can grasp the maximum value of the lifting degree exceeding the small second hand numerical value range in the display period by confirming the numerical value indicated by the center pointer 13.
For example, when the user is performing air sports such as paragliding or hang gliding, the user can grasp the ascending / descending degree when the user can ascend most during the display period. Even users who do not perform air sports may be interested in knowing the maximum value of the lift or the minimum value of the lift when boarding a high-speed elevator. In this case, the electronic timepiece W can notify the user of the maximum value of the lift or the minimum value of the lift. In addition, there may be an interest in knowing how much a sudden rise or fall occurred when a user boarded a roller coaster. In this case, the electronic timepiece W can notify the user of the maximum value or the minimum value of the elevation degree.
In the first embodiment, the user can grasp the elevation degree. The reason for grasping the elevation is that it is important to obtain the elevation when the user is performing air sports such as paragliding or hang gliding. An important reason is that the user can use the ascending / descending degree that can be grasped to search for an updraft or to avoid a downdraft.

Further, the elevation calculation unit 62 calculates the elevation based on the atmospheric pressure measured by the atmospheric pressure sensor 4. Specifically, the elevation calculation unit 62 calculates the elevation using equation (1). In addition to equation (1), there are the following two methods for calculating the degree of elevation. In the first method, the electronic timepiece W calculates the first position and the second position from the satellite signal obtained from the position information satellite, calculates the height direction distance between the calculated first position and the second position, Based on the time at the first position, the time at the second position, and the calculated distance in the height direction, the elevation is calculated. In the second method, the electronic timepiece W has a triaxial acceleration sensor, extracts acceleration in the height direction from triaxial acceleration obtained from the triaxial acceleration sensor, and integrates the extracted acceleration. Calculate the elevation.
However, in the first method, in order to calculate the position, satellite signals are received from at least four satellites, and values of four variables such as latitude, longitude, altitude, and time must be obtained. More processing load is required than the method. In the second method, since acceleration must be continuously measured from the measurement start position to the current position, the processing load is higher than the method according to the present embodiment. As described above, the electronic timepiece W can reduce the processing load on the electronic timepiece W as compared with the first method and the second method.

  Further, as described in FIG. 1, the numerical color of the measurement result is white. On the other hand, the time symbol color is orange. The symbol background color is black. Thus, the brightness difference between the measurement result numeral color and the symbol background color is larger than the brightness difference between the time symbol color and the symbol background color. In general, the greater the difference in brightness between the foreground color and the background color, the easier it is to see the foreground color. Comparing the measurement result with the time, the measurement result is more important information. Therefore, the electronic timepiece W can make it easier to see the numbers indicating at least a part of the measurement result more important than the time. The lightness is an index representing the brightness of the color, and can be represented by a numerical value from 0 to 10 with whiteness having a reflectance of 100% as lightness 10. The brightness can be measured with a colorimeter or a spectrocolorimeter.

  Further, the color difference between the measurement result numeral color and the symbol background color is larger than the color difference between the time symbol color and the symbol background color. Here, the color difference between the first color and the second color is obtained by, for example, the following equation (2).

  Color difference = ((R2-R1) ^ 2 + (G2-G1) ^ 2 + (B2-B1) ^ 2) ^ 0.5 (2)

  R1, G1, and B1 are a red element of the first color, a green element of the first color, and a blue element of the first color, respectively. Similarly, R2, G2, and B2 are a red element of the second color, a green element of the second color, and a blue element of the second color, respectively. The color difference can be calculated from the values of R1, G1, B1, R2, G2, and B2 measured with a spectrocolorimeter or a color difference meter.

  Generally, the greater the color difference between the foreground color and the background color, the easier it is to distinguish the foreground color from the background color, and the foreground color becomes easier to see. Therefore, the electronic timepiece W can make it easier to see the numbers indicating at least a part of the measurement result more important than the time.

  In addition, as described in FIG. 1, the measurement result pointer color is white. On the other hand, the time indicator color is orange. Thus, the brightness difference between the measurement result indicator color and the symbol background color is larger than the brightness difference between the time indicator color and the symbol background color. Therefore, the electronic timepiece W can make the tip of the pointer related to the measurement result more important than the time easier to see.

  Further, the color difference between the measurement result indicator color and the symbol background color is larger than the color difference between the time indicator color and the symbol background color. Therefore, the electronic timepiece W can make the tip of the pointer related to the measurement result more important than the time easier to see.

B. Second Embodiment In the second embodiment, the center pointer 13 indicates the maximum value of the lift, and the numerical display short hand 32 and the numerical display long hand 33 indicate the scale 31a according to the value of each digit of the minimum lift. Instruct. Hereinafter, a second embodiment will be described. In addition, about the element which an effect | action and function are the same as 1st Embodiment in each form and each modification illustrated below, the detailed description of each is abbreviate | omitted suitably using the code | symbol used in 1st Embodiment. To do. Furthermore, the following elements are assumed to be elements relating to the second embodiment, unless otherwise specified, for the sake of omitting the description.

B. 1. Operation Mode Flowchart The elevation display mode will be described using a specific flowchart.

  FIG. 11 shows a flowchart of the elevation display mode. Of the steps in the flowchart shown in FIG. 11, steps S21 to S25 are the same as the processes in steps S1 to S5 shown in FIG.

  After the process of step S25 is completed, the display control unit 61 refers to the storage unit 5 and calculates the minimum value of the elevation in the display period (step S26). The display control unit 61 controls the numerical display short hand 32 and the numerical display long hand 33 so that the numerical display short hand 32 and the numerical display long hand 33 indicate the value of each digit of the minimum value of the elevation degree (step S27). ).

  Next, the control unit 6 determines whether one minute has elapsed since the operation mode was set to the elevation display mode or whether a pressing operation of the operation button B was detected (step S28). If one minute has not elapsed and the pressing operation of the operation button B has not been detected (step S28: No), the elevation calculation unit 62 performs the process of step S22 one second after the previous execution. Run. On the other hand, when one minute has passed or the pressing operation of the operation button B is detected (step S28: Yes), the control unit 6 ends the series of processes.

B. 2. Effect of Second Embodiment According to the second embodiment, the user can grasp the maximum value of the lift and the minimum value of the lift at a time. Furthermore, when trying to display a value of a plurality of digits with one pointer, a large scale in which numbers indicating the values of the plurality of digits are arranged is necessary. For example, if a two-digit value is displayed, a scale indicating “0” to “99” is required. Since the large scale occupies a large area of the display unit 10, it is preferable that the scale is small. On the other hand, according to the second embodiment, since the numerical display short hand 32 and the numerical display long hand 33 indicate the value of each digit of the minimum value, the scale 31a indicating “0” to “9” is displayed. It suffices to use the scale 14c indicating "0" to "99". As shown in FIG. 1, the scale 31a is smaller than the scale 14c. Therefore, in the second embodiment, it is possible to display the values of a plurality of digits of the minimum value of the lifting degree while using the small scale 31a.

C. Modifications The above embodiments can be variously modified. Specific modifications are exemplified below. Two or more aspects arbitrarily selected from the following examples can be appropriately combined within a range that does not contradict each other. In addition, about the element which an effect | action and a function are equivalent to embodiment in the modification illustrated below, the code | symbol referred by the above description is diverted and each detailed description is abbreviate | omitted suitably.

C. 1. First Modification In the compass mode in each of the above embodiments, a true north direction could be indicated. On the other hand, in the compass mode in the first modified example, in addition to indicating the direction of true north, it is possible to indicate the azimuth angle of the waypoint Wpt (see FIG. 15) and the distance from the current position to the waypoint Wpt. The waypoint Wpt is point information on a route in navigation, and is, for example, a position registered in advance in the storage unit 5. For example, when the user makes a business trip, the electronic timepiece W registers the location of the hotel serving as the user's accommodation in the waypoint Wpt by the user's operation. When the user goes out of the hotel and returns to the hotel, the electronic timepiece W indicates the azimuth of the hotel position as the waypoint Wpt and the distance from the current position to the hotel position by the compass mode. Can do.
Furthermore, in the first modification, it is possible to set a displayable range of the distance from the current position to the waypoint Wpt. The displayable range is hereinafter referred to as “range”. More specifically, in the first modified example, the electronic timepiece W has a distance range to the waypoint Wpt, a first range of 0 m or more and less than 10 km, a second range of 0 m or more and less than 100 km, and a range of 0 m to less than 1000 km. It can be set to any of the third ranges.

  FIG. 12 is a plan view of an electronic timepiece W according to the first modification. The following elements are assumed to be elements relating to the first modification unless otherwise specified, for the sake of brevity. FIG. 12 shows an enlarged region EnReg1 obtained by enlarging the region Reg1.

  As shown in the enlarged region EnReg1, the display unit 10 includes a 7 o'clock side information display unit 70. The 7 o'clock side information display unit 70 includes a part of the dial 10a.

The 7 o'clock side information display unit 70 has a scale 71. The scale 71 shows a plurality of powers of 10 that can be instructed by the center pointer 13. Specifically, a number “100”, a number “1000”, and a number “10000” are arranged on the scale 71 as numbers indicating a plurality of powers of 10. Hereinafter, the power of 10 indicated on the scale 71 is referred to as “range value”. When the center pointer 13 indicates the first range value “100”, the 7 o'clock side information display unit 70 indicates that the current range is the first range. When the center pointer 13 indicates the second range value “1000”, the 7 o'clock side information display unit 70 indicates that the current range is the second range. When the center pointer 13 indicates the third range value “10000”, the 7 o'clock side information display unit 70 indicates that the current range is the third range.
In the following, for simplification of description, the next range after the first range is the second range, the next range after the second range is the third range, and the next range after the third range is the first range.

  Since the numbers in the scale 71 are used for setting the range, they are not used for indicating the measurement result and are not related to the time. Therefore, the number in the scale 71 can be either white or orange. In the first modification, the number in the scale 71 is orange.

  In the example of FIG. 12, since the center pointer 13 indicates the number “100”, it indicates that the current range is the first range. When the current range is the first range, each number on the scale 31 a is used as the value of the first digit of “km” with respect to the numerical display short hand 32, and “m” with respect to the numerical display long hand 33. Used as the value of hundreds of digits. Similarly, when the current range is the second range, each number on the scale 31 a is used as the value of the tenth digit of “km” with respect to the numerical display short hand 32, and to the numerical display long hand 33. Used as the value of the first digit of “km”. Similarly, when the current range is the third range, each number on the scale 31 a is used as the value of the hundreds digit of “km” with respect to the numerical display short hand 32, and Used as the decimal place value of “km”.

C. 1.1. Outline of Compass Mode In the compass mode, the electronic timepiece W can indicate the direction of true north as well as the direction and distance to the waypoint Wpt. When the operation mode is set to the compass mode, the display unit 10 displays the center pointer 13 based on the magnetic north direction measured by the three-axis magnetic sensor 3 so that the center pointer 13 faces true north. Control.

  Further, the display unit 10 indicates the direction of the waypoint Wpt according to the direction of the small second hand 41. Further, the display unit 10 indicates the distance of the waypoint Wpt by the numerical values indicated by the numerical display short hand 32 and the numerical display long hand 33.

C. 1.2. Configuration of Control Unit 6 According to First Modification FIG. 13 is a configuration diagram of the control unit 6. The control unit 6 reads and executes the program stored in the storage unit 5, thereby causing the display control unit 61, the elevation calculation unit 62, the atmospheric pressure trend calculation unit 63, the azimuth calculation unit 65, and the range setting unit 66. And the present position calculation part 67 is implement | achieved. Hereinafter, the configuration of the control unit 6 will be described for the compass mode.

C. 1.2.1. Configuration of Control Unit 6 in Compass Mode In the compass mode, the range setting unit 66 sets a range. Specifically, the range setting unit 66 acquires the current range from the storage unit 5. When the current range is not set, the range setting unit 66 acquires the initial value of the range stored in the storage unit 5. The range setting unit 66 outputs the acquired range to the display control unit 61. The display control unit 61 controls the center pointer 13 so as to indicate the range value of the acquired range.
Next, the range setting unit 66 sets a range according to the number of pressing operations of the operation button A for a predetermined time or more. For example, when the operation button A is pressed once for a predetermined time or longer, the range setting unit 66 sets the range to the next range after the current range. When the range is set, the range setting unit 66 outputs the set range to the display control unit 61. The display control unit 61 controls the center pointer 13 so as to indicate the range value of the set range.

  The current position calculation unit 67 acquires a satellite signal from the GPS receiver 2 and calculates the coordinates of the current position based on the acquired satellite signal. The current position calculation unit 67 outputs the calculated coordinates of the current position to the display control unit 61.

  The display control unit 61 calculates the distance from the current position to the waypoint Wpt and the azimuth angle of the waypoint Wpt from the coordinates of the position registered in advance in the storage unit 5 and the coordinates of the current position calculated by the current position calculation unit 67. Is calculated.

The display control unit 61 instructs the numerical display short hand 32 and the numerical display long hand 33 to indicate the value of the scale 31a according to the first value obtained by dividing the distance from the current position to the waypoint Wpt by the current range value. Control. Under the control of the display control unit 61, the numerical display short hand 32 and the numerical display long hand 33 indicate the numerical value of the scale 31a according to the first value. Specifically, the display control unit 61 indicates the tenth digit value of the first value with the numerical value display short hand 32 and indicates the first digit value with the numerical value display long hand 33. For example, it is assumed that the calculated distance is 1200 m and the current range value is “100”. In this case, since the first value obtained by dividing 1200 by 100 is 12, the display control unit 61 controls the numerical display short hand 32 and the numerical display long hand 33 so that the numerical display short hand 32 indicates “1”. The numerical display long hand 33 indicates “2”.
The calculated azimuth angle is the azimuth angle of the waypoint Wpt in the global coordinate system. Therefore, the display control unit 61 converts the true north calculated by the azimuth calculation unit 65 into the azimuth angle of the waypoint Wpt in the local coordinate system of the electronic timepiece W. The display control unit 61 controls the small second hand 41 according to the direction of the small second hand 41 so as to indicate the converted azimuth angle.

C. 1.3. Operation Mode Flowchart The compass mode will be described using a specific flowchart.

C. 1.3.1. Compass Mode Flowchart FIG. 14 shows a compass mode flowchart. When the operation button A is pressed several times by the user and the mode pointer 21 indicates the character string 23c, the electronic timepiece W sets the operation mode to the compass mode. When the operation mode is set to the compass mode, the control unit 6 accepts the one-step pull-out operation of the crown D (Step S31). When the display control unit 61 accepts the pull-out operation of the crown D, the display control unit 61 controls the center pointer 13 so as to instruct the range value of the current range (step S32).

  The control unit 6 determines whether or not a pressing operation of the operation button A for a predetermined time or longer is detected (step S33). When the pressing operation of the operation button A for a predetermined time or longer is detected (step S33: Yes), the display control unit 61 controls the center pointer 13 so as to instruct the range value of the next range (step S34). After the process of step S34 or when the pressing operation of the operation button A for a predetermined time or longer is not detected (step S33: No), the control unit 6 determines whether or not the crown D pressing operation is detected. (Step S35). When the pushing operation of the crown D is not detected (step S35: No), the control unit 6 returns the process to step S33.

  On the other hand, when the pushing operation of the crown D is detected (step S35: Yes), the range setting unit 66 sets the range of the range value currently instructed by the center pointer 13 as the current range (step S36). Next, the control unit 6 accepts a pressing operation for a predetermined time or more of the operation button B (step S37). When a pressing operation of the operation button B for a predetermined time or more is accepted, the current position calculation unit 67 starts calculating the coordinates of the current position, and the direction calculation unit 65 starts calculating the true north direction. Then, the current position calculation unit 67 calculates the coordinates of the current position (step S38). Further, the azimuth calculating unit 65 calculates the true north azimuth based on the direction of geomagnetism measured by the three-axis magnetic sensor 3 (step S39). The display control unit 61 controls the center pointer 13 so as to indicate the direction of true north (step S40).

  Then, the display control unit 61 calculates the distance from the current position to the waypoint Wpt based on the coordinates of the current position and the coordinates of the waypoint Wpt stored in the storage unit 5 (step S41). Further, the display control unit 61 calculates the azimuth angle of the waypoint Wpt in the local coordinate system of the electronic timepiece W based on the coordinates of the current position, the coordinates of the waypoint Wpt, and the true north azimuth (step S42). The display control unit 61 controls the numerical display short hand 32 and the numerical display long hand 33 so as to indicate the calculated distance according to the set range (step S43). Further, the display control unit 61 controls the small second hand 41 so as to indicate the azimuth angle of the waypoint Wpt (step S44). After the process of step S44 ends, the control unit 6 ends the series of processes. The directions of the numerical display short hand 32, the numerical display long hand 33, the center pointer 13 and the small second hand 41 in the compass mode will be described with reference to FIG.

  FIG. 15 shows an example of the direction of the pointer in the compass mode. Through the processing in step S40, the center pointer 13 indicates the true north direction. Further, the numerical display short hand 32 and the numerical display long hand 33 indicate the calculated distance L by the process of step S43. In addition, the small second hand 41 indicates the calculated azimuth angle ψ by the process of step S44.

C. 1.4. Effect of First Modification As described above, the numerical display short hand 32 and the numerical display long hand 33 indicate the numerical value of the scale 31a according to the value obtained by dividing the distance from the current position to the waypoint Wpt by the current range value. Instruct. Thereby, the electronic timepiece W can increase the numerical value that can be displayed by using the scale 31a by appropriately changing the range as compared with the case where the range is not changed. For example, it is assumed that the distance from the current position to the waypoint Wpt is 10 km or more and less than 100 km, and the range value is set to “100”. In this assumption, since the range value is “100” and exceeds the displayable numerical value, the numerical display short hand 32 and the numerical display long hand 33 indicate the number “0” on the scale 31a and indicate the correct distance. I can't. Therefore, the electronic timepiece W sets the range value to “10000” by the user's operation, so that the numerical value display short hand 32 and the numerical value display long hand 33 have the appropriate scale 31a corresponding to the distance from the current position to the waypoint Wpt. It becomes possible to indicate a correct number.
The user can browse the numerical values indicated by the numerical display short hand 32 and the numerical display long hand 33 and appropriately determine, for example, whether to walk to the waypoint Wpt or move by taxi.

C. 2. Second Modification FIG. 16 is a plan view of an electronic timepiece W according to a second modification. The electronic timepiece W in the second modification is a combination quartz (CQ) timepiece. The electronic timepiece W in the second modified example does not have the 2 o'clock side information display unit 30 and the date display unit 50, and the 6 o'clock side information display unit 20 is replaced with an LCD (Liquid Crystal Display) 29. The following elements are assumed to be elements relating to the second modification unless otherwise specified, for the sake of brevity. The LCD 29 displays an image indicating a character string indicating the current operation mode and an image indicating a character string relating to the current operation mode.

  Specifically, the LCD 29 shown in FIG. 16 displays an image 29a and an image 29b. The image 29a shows a character string “MODE” indicating the operation mode and a character string “BAR” where the current operation mode indicates the atmospheric pressure display mode. The image 29b shows the atmospheric pressure “3776m” at the current position as a character string related to the atmospheric pressure display mode.

  FIG. 17 shows a configuration diagram of the electronic timepiece W. In FIG. 17, the same components as those shown in FIG.

  The electronic timepiece W includes an LCD 29 and an LCD driver 501 as a configuration related to the 6 o'clock side information display unit 20. The LCD driver 501 drives the LCD 29.

C. 3. Other Modifications In the first embodiment, the center pointer 13 indicates the maximum value of the lift, but it may indicate the minimum value of the lift. Furthermore, when the center pointer 13 indicates the minimum value of the elevation, the center pointer 13 may indicate the absolute value of the minimum value of the elevation using the scale 14c. Alternatively, the center pointer 13 may indicate a value of 100− (absolute value of the minimum value of the lift) using the scale 14c when displaying the minimum value of the lift. For example, if the minimum value of the elevation is −10 m / second, the center pointer 13 indicates that the minimum value of the elevation is −10 m / second by instructing 100−10 = 90.

  Alternatively, in order to imitate a general elevator, the center pointer 13 may regard the position of the numeral “75” on the scale 14c as the maximum value of the elevation degree being 0 m / second. Then, the center pointer 13 is used to display the maximum value of the ascending / descending degree from the number “75” to the number “25” via the number “0” in the clockwise direction on the scale 14c. Similarly, the center pointer 13 is used for displaying the minimum value of the lifting degree from the number “75” of the scale 14 c to the number “25” via the number “50” counterclockwise. .

  In the second embodiment, the numerical display short hand 32 and the numerical display long hand 33 indicate the minimum value of the elevation, but other pointers may indicate the minimum value of the elevation. For example, the minute hand 12 (example of “third pointer”) may indicate the minimum value of the elevation degree. Thereby, the user can grasp the maximum value of the lift and the minimum value of the lift at a time.

  In the second embodiment, the center pointer 13 indicates the maximum value of the lift, and the numerical display short hand 32 and the numerical display long hand 33 indicate the minimum value of the lift, but the present invention is not limited to this. The center pointer 13 indicates the scale 14c according to one of the maximum and minimum values of the lift, and the numerical display short hand 32 and the numerical display long hand 33 indicate the other of the maximum and minimum values of the lift. The scale 31a may be indicated according to the value of the digit.

  In the first modified example, numbers “100”, “1000”, and “10000” are arranged in the 7 o'clock side information display unit 70 as powers of 10 that can be indicated by the center pointer 13. It is not limited to numbers. For example, the power of 10 may be a number “1” that is 10 to the 0th power, or may be a number “0.1” that is a power of −1. In addition, in the 7 o'clock side information display unit 70, a number expressed as an index such as a number “105” or “1.0E5” may be arranged instead of the number “10000”.

  The 6 o'clock side information display unit 20 in the second modified example includes the LCD 29, but may include an organic EL (ElectroLuminescence) display instead of the LCD 29.

In each of the above embodiments, the display period is a period from the time when the operation mode is set to the elevation display mode to the time when the operation mode is set to a mode other than the elevation display mode, but is not limited thereto. For example, the display period may be from one minute before the current time to the current time. In this case, the start of the display period changes every moment. When the start period of the display period varies, the first time at which the elevation is the maximum value or the minimum value in the display period before the change may not be included in the display period after the change. In order to simplify the description, an example in which the maximum value of the elevation is displayed will be described. When the storage unit 5 stores only the maximum value of the elevation in the display period before the change, the maximum value of the elevation in the display period after the change, that is, the next largest increase / decrease after the first time. It cannot be calculated.
However, in each of the above embodiments, it is possible to calculate the maximum or minimum value of the elevation in the display period after the change from the elevation in units of time stored in the storage unit 5.

When displaying the altitude, the 10 o'clock side information display unit 40 may use the scale 42p, the scale 42m, and the scale 42z as logarithmic scales. For example, in FIG. 1, the number “1” on the scale 42 p indicates 10 m, the number “2” on the scale 42 p indicates 100 m, the number “3” on the scale 42 p indicates 1000 m, and the number “ “4” may indicate 10,000 m, and the number “5” on the scale 42p may indicate 100,000 m. Similarly, the number “1” on the scale 42m may indicate −10 m, and the number “2” on the scale 42m may indicate −100 m. In addition, when the small second hand 41 displays the temperature or the ultraviolet intensity, the 10 o'clock side information display unit 40 indicates the positive sign 43p if the tendency of the temperature or the ultraviolet intensity is positive, and the tendency of the temperature or the ultraviolet intensity is If negative, a negative sign 43m may be indicated. The user can easily read the tendency of the temperature or ultraviolet intensity indicated by the positive sign 43p and the negative sign 43m.

Alternatively, the measurement result numeral color and the time symbol color may be any color as long as the color difference between the measurement result numeral color and the symbol background color is larger than the color difference between the time symbol color and the symbol background color. Similarly, the measurement result pointer color and the time pointer color may be any color as long as the brightness difference between the measurement result pointer color and the symbol background color is larger than the lightness difference between the time pointer color and the symbol background color. Alternatively, the measurement result indicator color and the time indicator color may be any color as long as the color difference between the measurement result indicator color and the symbol background color is larger than the color difference between the time indicator color and the symbol background color.
For example, if the brightness of the measurement result numeric color and the brightness of the symbol background color are the same, the brightness difference between the measurement result numeric color and the symbol background color and the brightness difference between the time symbol color and the symbol background color are the same. Become.
