  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  FIG. 1 is a front view of an electronic timepiece according to an embodiment of the present invention.

  An electronic timepiece 1 according to an embodiment of the present invention is a pointer-type electronic timepiece that simultaneously displays time and displays related to other functions using a plurality of hands. The electronic timepiece 1 has a dial 11 provided with a scale and a mark for displaying time on the inside surrounded by a casing 10 and a windshield covering the front surface, and a dial 11 that is rotatable on the dial 11. An hour hand 2, a minute hand 3, a second hand 4 (hereinafter collectively referred to as hands 2 to 4), a 24-hour hand 6, a function hand 7, and switches B1 to B4 provided on both side portions of the casing are provided. Further, a date wheel 5 is held on the back side of the dial 11 so as to be rotatable about the same axis as the hands 2 to 4. One of the numerical values 1 to 31 indicated on a predetermined concentric circle on the surface of the date dial 5 is exposed from the rectangular opening 13 provided in the 3 o'clock direction of the dial 11. It is the composition which becomes.

  The hands 2 to 4 are rotated over almost the entire area of the dial 11, while the 24-hour hand 6 is rotated within a small window 16 provided at the 9 o'clock position of the dial 11, and the function hand 7 is The dial 11 is configured to rotate within a small window 17 provided at the 6 o'clock position. Therefore, the 24-hour hand 6 and the function hand 7 rotate around an axis different from the hands 2 to 4 respectively.

  The inside of the circular small window 17 is not particularly limited, but the time from the current time to the sunset time is displayed using the direction of the small window 17 from 12:00 to 3 o'clock. Using the direction from 6 o'clock to 9 o'clock in the window 17, the time from the current time to the sunrise time is displayed. The scale of the small window 17 is set from 120 minutes before the sunrise time to the sunrise time and from 120 minutes before the sunset time to the sunset time. Also, the time intervals (5 minute intervals) indicated by the scales from 60 minutes before sunrise time to sunrise time and from 60 minutes before sunset time to sunset time are from 120 minutes before sunrise time, respectively. Compared to the time interval indicated by the scale from 60 minutes before the sunrise time and from 120 minutes before the sunset time to 60 minutes before the sunset time (10 minute intervals), these scales When the function hand 7 indicates, the time can be displayed in more detail.

  In addition, for example, the small window 17 and the function hand 7 can be used when inputting the setting of latitude and longitude data of the position for obtaining the sunrise time and the sunset time. Or it is good also as setting using another guideline.

  FIG. 2 is a block diagram showing an internal configuration of the electronic timepiece 1.

  The electronic timepiece 1 includes a control unit 80 (pointer drive control means, time difference calculation means, daylight time calculation means) that incorporates a CPU (Central Processing Unit) and controls the overall operation of the timepiece, A RAM (Random Access Memory) 81 that provides a working memory space for the CPU, various programs for performing timekeeping operation processing, calculation of sunrise time and sunset time, and ROM that stores various setting data (Read Only Memory) 82, a clock circuit 89 (time measuring means) that counts time by inputting a predetermined frequency signal from an oscillation circuit (not shown), and switches 80 to B4 are operated to control unit 80. A switch unit 90 for outputting a signal, a first step motor 33 for rotating the hour hand 2 and the minute hand 3 by a predetermined angle through a gear train mechanism 23 including a plurality of gears, a second hand 4 and a date wheel 5 Second to fifth step motors 34 to 37 for rotating the 24-hour hand 6 and the function hand 7 by a predetermined angle via gear train mechanisms 24 to 27 each including a plurality of gears, and a command from the control unit 80 In response to this, there are provided drive circuits 43 to 47 that send signals for driving the first to fifth step motors 33 to 37, respectively.

  The RAM 81 has a position storage unit 81a (position storage unit) that stores the latitude and longitude data input by operating the switches B1 to B4, and the sunrise time and date calculated by the CPU of the control unit 80. And a day and night time storage unit 81b (day and night time storage means) for storing the entry time. The sunrise time and sunset time are overwritten each time in the sun rise / fall time storage unit 81b every time calculated by the CPU of the control unit 80.

  The position coordinates stored in the position storage unit 81 b are not limited to the current position of the user of the electronic timepiece 1. It is also possible to display the time from the current time until a set point around the world, for example, the sunrise time in Paris and the sunset time.

  The control unit 80 rotationally drives the hands 2 to 4, the 24-hour hand 6, and the date wheel 5 based on the time data input from the timing circuit 89, and displays the time and date. In addition, the control unit 80 stores the calculated sunrise time and sunset time in the sun rise and fall time storage unit 81b, or the sunrise time and sunset time data stored in the sun rise and fall time storage unit 81b. The time is read and compared with the time data input from the clock circuit 89, and the time from the current time to sunrise and sunset is calculated. Then, the control unit 80 rotates the functional hand 7 based on the calculated time from the current time to the sunrise time or the time from the sunset time.

  When calculating the sunrise time and sunset time, the CPU calls the calculation program from the ROM 82, acquires the latitude and longitude data set from the position storage unit 81a, and reads the date read from the timing circuit 89. Calculates and obtains values of declination and meridian indicating the position of the sun. Using these acquired values, the sunrise time and sunset time are calculated. At this time, in an area adopting daylight saving time, the daylight saving time can be calculated according to the daylight saving time by setting the daylight saving time automatically or manually.

  Next, the operation of the function hand 7 at the time of sunrise and sunset will be described.

  FIG. 3 is a diagram showing a display example of sunrise and sunrise time by the function hand 7 on the small window 17. FIG. 4 is a diagram showing a display example of the sunset time and the sunset time by the function hand 7 on the small window 17.

  As shown in FIG. 3A, when the current time is 120 minutes before the sunrise time, the functional hand 7 indicates a scale 171 (hand movement start scale before sunrise) indicating 120 minutes before the sunrise time. . The function hand 7 indicates a scale 172 in the 7 o'clock direction 60 minutes before the sunrise time (FIG. 3B), and indicates a scale 173 in the 8 o'clock direction 30 minutes before the sunrise time (FIG. 3). (C)), the sunrise time indicates a scale 174 (sunrise time scale) in the 9 o'clock direction (FIG. 3D). That is, the functional hand 7 rotates clockwise at a predetermined frequency until the sunrise time. The number of steps per round of the functional hand 7 is not particularly limited, but is, for example, 60 steps. In this case, the function hand 7 rotates clockwise by one step every 10 minutes from 120 minutes before the sunrise time to 60 minutes before the sunrise time, and 5 seconds from 60 minutes before the sunrise time to the sunrise time. Rotate clockwise by one step every minute. When the sunrise time has passed, the function hand 7 stops while pointing to the scale 174 until the hand movement before the sunset time is started.

  Next, as shown in FIG. 4 (A), when the current time is 120 minutes before the sunset time, the function hand 7 rotates 90 degrees clockwise from the scale 174 in the 9 o'clock direction, It indicates a scale 175 in the 12 o'clock direction indicating 120 minutes before the time (hand movement start scale before entering the sun). Subsequently, the function hand 7 indicates the scale 176 in the 1 o'clock direction 60 minutes before the sunset time (FIG. 4B), and indicates the scale 177 in the 2 o'clock direction 30 minutes before the sunset time. (FIG. 4 (C)), and the sunset time indicates a scale 178 (sunset time scale) in the 3 o'clock direction (FIG. 4 (D)). The moving direction and timing of the function hand 7 before entering this day are the same as the moving direction and timing of the movement before sunrise, respectively. That is, the function hand 7 rotates clockwise by one step every 10 minutes from 120 minutes before the sunset time to 60 minutes before the sunset time, and enters the sunset from 60 minutes before the sunset time. Until the time, it rotates clockwise by one step every 5 minutes. When the sunset time has passed, the function hand 7 stops while pointing the scale 178 until movement before the sunrise time is started.

  Here, for example, when the sun setting time is not obtained due to the polar night or the white night, for example, the scale 175 (120 minutes before the time when the function hand 7 is 12 o'clock in the day at 12 o'clock) is displayed without performing the above display. An error is displayed by stopping while pointing to the (error display position). This error display is performed more clearly, for example, by providing a scale for displaying an error separately several steps before the hand setting start scale 175 before entering the sun, and the function hand 7 indicates the scale for displaying the error. It is also possible to do so.

  In the electronic timepiece 1, only the time before the sunrise time and the time before the sunset time is calculated and displayed. However, for example, one hour after the sunrise time or after the sunset time is continuously displayed. May be calculated and displayed.

  Further, indications and scales indicating “daytime”, “nighttime”, etc. are further provided in the small window 17, and the function hand 7 points to these scales so that from the sunrise time to 120 minutes before the sunset time. It may be configured to display the time zone between and the time zone between the sunset time and 120 minutes before the sunrise time.

  In addition, the time intervals indicated by the scales may all be the same. Conversely, for example, the sunrise time and the sunset time are 60 minutes to 15 minutes before, the sunrise time 15 minutes before the sunrise time, and the day. It is also possible to further change the time of the day from 15 minutes before the time of the day. Furthermore, it is good also as changing the space | interval of a scale more finely.

  Next, the flow of control processing executed by the CPU with respect to the operation for displaying the time from the current time to the sunrise time and the time from the sunset time will be described.

  FIG. 5 is a flowchart showing the control procedure of the time measuring process by the CPU.

  The process related to the display operation of the time from the current time to the sunrise time and the time from the sunset time is performed following the normal current time counting process and the hand movement process performed every second.

  First, when the timekeeping process is started, the CPU acquires current time data from the timekeeping circuit 89, and drives the one of the hands 2 to 4, the date wheel 5, and the 24-hour hand 6 at the timing that requires hand movement. An operation signal is sent to the circuits 43 to 46 (step S1).

  Subsequently, the process proceeds to step S2, and the CPU obtains the sunrise time and sunset time data from the daylight saving time storage unit 81b of the RAM 81, and determines whether any of these data is an error. To do. If it is determined that either the sunrise time or the sunset time data is an error, the process proceeds to step S3, and the CPU sends an operation signal to the drive circuit 47 to place the function hand 7 in the error display position. Move to 175. Then, the process proceeds to step S4 to determine whether or not the current time is 0: 0: 0, that is, whether the date has changed. If it is determined that it is not 0: 0: 0, the time measurement process is terminated without performing the subsequent processes.

  If it is determined in the determination process of step S4 that it is 0: 0: 0, the process proceeds to step S5, and the CPU calculates the sunrise time and the sunset time on the changed date, This calculation result is stored in the daylight saving time storage unit 81b. Subsequently, it is determined whether or not these sunrise times and sunset times are correctly calculated (step S6). If it is determined again that any data of the sunrise time or the sunset time is an error, the timing process is terminated as it is.

  If it is determined in the determination process in step S2 or the determination process in step S6 that the sunrise time and sunset time data are not errors, the process proceeds to step S7. Then, the CPU calculates a time difference between these sunrise time and sunset time and the current time acquired in step S1.

  As a result of the calculation process in step S7, when it is determined that the current time is before the predetermined time of the sunrise time (120 minutes in the present embodiment), the process proceeds to step S8, and the CPU sets the function hand 7 to 6. An operation signal is continuously sent to the drive circuit 47 until the hourly pre-sunrise hand movement start scale 171 is indicated. Then, the time measurement process ends.

  If it is determined as a result of the calculation process in step S7 that the current time is a predetermined time (120 minutes) before the sunset time, the process proceeds to step S9, and the CPU sets the function hand 7 to 12:00. The operation signal is continuously sent to the drive circuit 47 until the hand movement start scale 175 before entering the direction day is indicated. Then, the time measurement process ends.

  In addition, as a result of the calculation process in step S7, the current time is between a predetermined time before the sunrise time and the sunrise time, or the current time is between the predetermined time before the sunset time and the sunset time. If it is determined, the process proceeds to step S10, and the hand movement process of the functional hand 7 is performed. That is, a predetermined hand movement timing (in this embodiment, the sunrise time and the sunset time are every 10 minutes from 120 minutes before to 60 minutes before, the sunrise time and the sunrise time from 60 minutes before the sunset time, The CPU sends an operation signal to the drive circuit 47 to move the function hand 7 clockwise by one step. Then, the time measurement process ends.

  If it is determined as a result of the calculation process in step S7 that the current time is the second following the sunset time, the process proceeds to step S11, and the CPU determines the sunrise time and sunset time of the next day. Is calculated. And CPU memorize | stores these time in the daylight saving time memory | storage part 81b, and complete | finishes a time measuring process.

  If it is determined as a result of the calculation process in step S7 that the other time does not branch to any of steps S8 to S11, that is, the current time is 120 minutes and 1 second before the sunrise time, the current time is sunrise. After 1 second from the time until 120 minutes and 1 second before the sunset time, and after 2 seconds after the current sunset time, the timing process ends.

  Note that the timing for calculating the sunrise time and the sunset time is not necessarily limited to the second following the sunset time and 0 hours, 0 minutes, and 0 seconds. Also, once the sunrise time and sunset time are calculated and the time from the current time to sunrise time and the time until sunset time are calculated, each second within the processing program or using a counter It is also possible to obtain by subtracting these time difference values.

[Modification]
FIG. 6 is a front view showing a modification of the display unit for the time from the current time to the sunrise time and the time from the sunset time.

  In the electronic timepiece 1B in this modified example, the small window 17B for displaying the time from the current time to the sunrise time and the time from the sunset time is an upper semicircle, and the function hand 7B is 180 degrees on the upper side. Except for the fact that it can be rotated only within the range, the configuration is the same as that of the above-described embodiment, and the same operation process is performed, so the description of the same portion is omitted.

  FIG. 7 shows a display example of sunrise and sunrise time by the function hand 7B on the small window 17B in this modification. FIG. 8 shows a display example of the sunset time and the sunset time by the function hand 7B on the small window 17B in this modification.

  In this modified example, a display “sunrise” indicating the sunrise time, a display “sunset” indicating the sunset time, and the current time to the sunrise time are arranged along the outer circular arc portion of the small window 17B. A scale and a numerical value indicating the time and the time until the sunset time are displayed. That is, by these displays, the upper 22.5 degree direction on the upper left of the upper half circle represents 120 minutes before the sunrise time, and thereafter, clockwise every 22.5 degrees, 60 minutes before the sunrise time, 30 days at the sunrise time. It is shown that it is minutes before, sunrise time, 120 minutes before sunset time, 60 minutes before sunset time, 30 minutes before sunset time, and sunset time. The left horizontal direction can be used as an error display position, for example.

  As shown in FIG. 7, when the current time is 120 minutes before the sunrise time, the functional hand 7B rotates to point to the pre-sunrise hand movement start scale 171B (FIG. 7A). The function hand 7B passes through a scale 172B (FIG. 7B) representing 60 minutes before the sunrise time and a scale 173B (FIG. 7C) representing 30 minutes before the sunrise time, and then the scale 174B (FIG. 7). Rotate clockwise until pointing to (D)). In addition, during the period from 60 minutes before the sunrise time to the sunrise time, the function hand 7B is compared with the rotational driving frequency (every 10 minutes) of the function hand 7B from 120 minutes before the sunrise time to 60 minutes before the sunrise time. Rotation drive frequency is doubled (every 5 minutes). After indicating the scale 174B at the sunrise time, the function hand 7B stops as it is until the hand movement before the sunset time is started.

  Further, as shown in FIG. 8, when the current time is 120 minutes before the sunset time, the function hand 7B is driven to fast-forward from the scale 174B and rotates so as to point to the incoming needle start scale 175B ( FIG. 8 (A)). And the function hand 7B passes the scale 176B (FIG. 8 (B)) which represents 60 minutes before the sunset time, and the scale 177B (FIG. 8 (C)) which represents 30 minutes before the sunset time. Rotate clockwise until pointing to 178B (FIG. 8D). In addition, during the period from 60 minutes before the sunset time to the sunset time, the rotational driving frequency of the function hand 7B from 120 minutes before the sunset time to 60 minutes before the sunset time (every 10 minutes) ), The rotational driving frequency of the functional needle 7B is doubled (every 5 minutes). The function hand 7B stops while pointing the scale 178B from the sunset time to 120 minutes and 1 second before the sunrise time, and then rotates and moves counterclockwise to the pre-sunrise hand movement start scale 171B.

  Alternatively, the function hand 7B may return to the pre-sunrise hand movement start scale 171B immediately after the sunset time, or may return to the pre-sunrise hand movement start scale 171B at, for example, 00: 00: 0.

  As described above, according to the electronic timepiece 1, 1 </ b> B of the above embodiment, the function hands 7, 7 </ b> B and the small windows 17, 17 </ b> B provided on the dial 11 are used to obtain the time from the current time to the sunrise time. The time and the time from the current time to the sunset time can be displayed. Therefore, the user can easily know the remaining time until the sunrise time and sunset time.

  Moreover, the time and date until the sunrise time are compared inside the electronic timepieces 1 and 1B by comparing the data of the sunset time and sunrise time stored in the day and night time storage unit 81b with the time data of the clock circuit 89. The time until the entry time can be obtained.

  Further, by providing the hands 2 to 4 and the function hands 7 and 7B, the normal time display and the time from the current time to the sunrise time and the time from the sunset time can be simultaneously displayed.

  Moreover, it is possible to input and set position coordinate data with the switches B1 to B4, and the sunrise time and sunset time of an arbitrary place are calculated based on the set position data and the sun position data. Therefore, the sunrise time and the remaining time until the sunset time can be displayed at any place in the world.

  In addition, since the time from the current time to the sunrise time and the time until the sunset time are displayed using the function hands 7 and 7B inside the small windows 17 and 17B on the dial plate 11, Can easily read the time from the current time to the sunrise time and the time from the sunset time by independent display.

  The present invention is not limited to the above-described embodiment, and various modifications can be made. For example, in the above embodiment, the display is performed 120 minutes before the sunrise time and the sunset time, but the value of the hand movement start time can be changed. The display of the time until the sunrise time can be configured to start from any time after the sunset time of the day before the sunrise, and the display of the time until the sunset time is The display can be started from an arbitrary time after the sunrise time immediately before the sunset.

  In the above embodiment, an error is displayed when there is an error in either sunrise time or sunset time. For example, in the high latitude area during daylight saving time, Even in such a case, if there is data on the sunrise time, it is possible to display before the sunrise time. Further, when there are two sunsets, it can be configured so that both can be displayed.

  In the above embodiment, the current time is used as a reference time for calculating the time difference between the sunrise time and the sunset time. However, the time different from the current time, the sunrise time and the sunset time It is also possible to calculate the time difference between. For example, when acting one hour earlier than the sunrise time or sunset time, a value obtained by adding one hour to the current time may be set as the reference time.

  In the above embodiment, the sunrise time and the sunset time are calculated inside the electronic timepiece. However, the means for acquiring the sunrise time and the sunset time is not limited to this. For example, it can be acquired from the outside using a wireless communication means. It is also possible to store a table of sunrise times and sunset times in the ROM 82 in advance.

  In the above embodiment, the sunrise time and the sunset time are calculated by directly inputting latitude and longitude values. For example, a list of latitude and longitude corresponding to the city name is stored in the ROM 82 in advance. It is also possible to configure so that coordinates are set by selecting a list number. Moreover, when there is no input, it is good also as setting to Tokyo automatically, for example.

  In the above embodiment, the sunrise time and the sunset time are calculated using the latitude and longitude values. However, altitude may be further added as the position coordinate value. In addition, the details shown in the embodiment, such as the positions and shapes of the small windows and scales, the number of pointers, and the presence or absence of other functions, can be appropriately changed without departing from the scope of the invention.
