Description

TECHNICAL FIELD OF THE INVENTION The present invention relates to a time information display device capable of knowing a time suitable for fishing and hunting of animals.

[Prior art and its problems] It has been conventionally known that the exercise of the moon influences the feeding activity of various animals including fish, for example,
In fishing, it is actually a good experience to catch fish well on a full moon or a new moon.

However, as a device for displaying the movement of the moon, an analog clock that displays the time with a pointer is provided with a moon age or moon phase display plate that makes one rotation in a cycle of about 29.5 days, and a clock that displays the phases of the moon. It has been known. Also, based on the idea that the lunar phase affects the tides, it is also possible to think of a device that stores tide data for each tide in the storage unit and calculates and displays the tide time based on this tide data. And is described in, for example, JP-A-61-202182.

However, in the analog timepieces with the above-mentioned age display plate, only the phases of the moon on that day can be known, and in the case where the tide time is displayed as in the above publication, the tide time is calculated. In addition to the drawback that it requires tide data for each region to do so and that a memory for storing the tide data for each region must be provided,
It merely displays the tide time, and the user has no choice but to judge the fishing condition based on his or her own thoughts based on the tide time.

The register N displays the current time in the current timetable time mode when the value of the register M is “0” (N =
"0"), current time correction (N = "1"), time difference, longitude, latitude correction (N = "2"), sunrise, sunset time display (N = "3") Is.

Further, the flag F ₀ is set when an hour carry occurs every hour when the current time of the register C is measured (F ₀ =
"1") is a flag that is, at this time the flag F ₀ is set, hour angle calculation as will be described later is executed. Similarly, the flag F ₁ is set by daily carry (F ₁ =
"1") is a flag that is, age operation is performed when the flag F ₁ is set. Further, in the fishing mode flag F ₂ is the value of the register M is "1", "1" is set when displaying the time most suitable for fishing, also sunrise value of the register M is "2", sunset This is a flag that is set to "1" when displaying the sunrise and sunset times in the time display mode.

The register J and the register K are registers for storing the sunrise / sunset time on the current date counted by the register C, and the register R and the register S are calculated by the daily carry of the register C described above, respectively. This is a register for storing the age data of, and hour angle data of the day calculated by hourly carry.

FIG. 5 shows an overall flow chart of the operation of the circuit configuration system shown in FIG. The system is usually in the waiting state (HALT) of step S1 in FIG.
At each time counting timing, the time counting process in the time counting unit equal to or less than the minute unit in step S2 is executed. In the timekeeping process below this minute, 1 /
It measures the time in units of 16 seconds, seconds and minutes, and outputs the hour carry signal when the minutes reach 60 minutes. Then, in the next step S3, the presence or absence of the hour carry signal is determined. When the hour carry signal is generated, the flag F ₀ is set to "1" in the next step S4. Here, the flag F ₀ is set to “1” because the time angle calculation of the moon, which will be described later, is performed on an hourly basis.

After that, the hourly timekeeping process of step S5 is executed. In this time unit time counting process, if a time carry signal is generated as a result of the minute or less time counting process, 1 is added to the time unit data,
When the added time exceeds 24 o'clock, a day carry signal is further output.

Then, in step S6, it is determined whether or not there is a daily carry signal. When the day carry signal is generated, step S7
To set "1" to the flag F ₁ . Here, the flag F ₁ is set to “1” because the age calculation described later is performed on a daily basis.

Then, the day, month, day of the week, and yearly clocking process of the next step S8 is executed. In this day, month, day of the week, and year timekeeping process, if a day carry signal is generated, the day of the week is changed, and 1 is added to the data of the day. Then, as a result of the addition, if carry occurs on a monthly basis or on an annual basis, the time data for each month and year is updated, and the updated time data is transferred to the time register C in the RAM 16.

If the time counting process is finished as described above, the flag F ₀ proceeds to step S9, it is determined whether it is set. If F ₀ = 0, that is, if the hour carry signal has not been generated, the process proceeds to the display process of step S15, and various data is displayed on the display unit 2 according to the values stored in the registers M and N. To do.

On the other hand, if F ₀ = 1 in step S9, it is determined that it is the calculation timing for calculating the hourly angle of the moon for each hour, and in the next step S10, the moonward angle calculation processing is executed.

The month hour angle calculation process in step S10 will be described in detail with reference to the flowchart of FIG.

In step S21 of FIG. 6, the current time stored in the register C, which is measured by the above-described time counting process, is
Based on the time difference data stored in the register B, it is converted into Greenwich time, and the Greenwich time is stored in the register Z ₀ of the RAM 16.

Then, in the next step S22, a variable t for obtaining the right ascension and the like of the moon on the side of Greenwich is calculated and stored in the register t ₀ of the RAM 16.

Here, the variable t is the time elapsed from January 1, 2000, 0:00 (Greenwich time: GMT = UT time) divided by the Julian century (36525 days). Year = YE, month = MN , Day = DA, hour = HO, W = (YE-1900) / 4 F = FRAC (W) A = INT (1461 × W) B = INT [(MN + 7) / 10] C = INT (1 -F) When D = INT [0.44 x (MN + 4.4)] Z = A + 31 x MN + DA + (B-1) x C-B x D + HO / 24, the variable t can be expressed by the following equation.

t = (Z-36556.5) / 36525 The variable t is calculated from this equation, and the calculated value is stored in the register Z ₁ of the RAM 16.

Next, in Step S23, the Greenwich time at UT = 0 is determined.

When Y = Z-25012, Greenwich sidereal time K is
It can be expressed by the following formula.

K = 24 × FRAC (0.0027379 × Y) The Greenwich sidereal time is calculated from the above formula, and the calculated value is stored in the register Z ₂ of the RAM 16.

In step S24, the RA of the moon at UT = 0 is calculated.

α = 32084.52539 x T + 14.55441 + 0.41925 x COS (477198.868 x T + 44.963) + 0.16358 x COS (962535.762 x T + 166.633) + 0.08494 x COS (413335.350 x T + 10.740) + 0.07104 x COS (1934.140) × T +324.960) +0.07048 × COS (964469.900 × T +41.590) +0.04389 × COS (890534.220 × T +145.700) = 24 × FRAC (α / 24)

From the above equation, the RA of the moon at UT = 0 is calculated, and the value is stored in the register Z ₃ of the RAM 16.

Next, the UT in Greenwich is obtained from the Greenwich sidereal time and the lunar red ascension obtained in step S25 as described above.
Calculate the hour angle of the month at 0:00.

Moon angle: JK can be calculated from the following formula.

K: sidereal time, α (m): lunar vision RA The longitude angle of the moon obtained from the above formula is stored in the register Z ₄ of RAM16.

Since the time angle of the moon at UT = 0 o'clock in Greenwich on the day is obtained as described above, the calculation for determining the time angle of the next day's month is performed.

First, in step S26, the date data of the time stored in the register Z ₁ is incremented by ₁ and stored in the register Z _n , and similarly to step S22, the variable t of the next day which is incremented by 1 is calculated, and the register Z _{5 of} the RAM 16 is stored. To store.

Next, as in step S27,28 At each step S23, S24, and calculates the viewing ascension of Greenwich sidereal time and the month in the time next day UT = 0, the values RAM16 of register Z ₆ and Z ₇ To store.

Then, in the next step S29, from the right star at the time of the next day of Greenwich and the moon at Greenwich,
Asked the corner time of the month of UT = 0, the register Z ₈ of the value RAM16
To be stored.

Since the time angle of the current day of UT = 0 o'clock in Greenwich and the time angle of the next day's month in Greenwich have been obtained by the above calculation, the lunar lunar day cycle is calculated in step S30.

The lunar lunar diurnal cycle is the time from when the lunar hour angle becomes 0h (0:00) to when the next lunar hour angle becomes 0h, and indicates the time of one cycle of the diurnal movement of the moon. There is.

Then, the lunar circadian cycle: LNR can be expressed by the following equation.

The lunar lunar diurnal cycle is calculated from the above formula and the value is stored in the register Z ₉ of the RAM 16.

FIG. 7 is a chart showing an example of the calculation of the lunar lunar cycle in an easy-to-understand manner.

For example, the hour angle of the month at UT = 0 in Greenwich is 3.
If the time angle of the moon at 8h and UT = 0 o'clock on the next day is 3.1h, then DJK = 3.1h−3.8h = −0.7h.

 Therefore, Lunar Diurnal Cycle: LNR can be calculated as LNR = 576 / (-0.7 + 24) = 24.7h.

Returning to FIG. 6, in the next step S31, a time (UT time) at which the hour angle of the month becomes 0:00 is calculated.

 The time when the hour angle becomes 0:00 can be expressed by the following equation.

In Greenwich, the time at which the hour angle of the month becomes 0 o'clock is obtained from the above formula, and the value is stored in the register Z ₁₀ of the RAM 16.

FIG. 8 is a chart showing the calculation at UT when the time angle is 0 o'clock in an easy-to-understand manner.

For example, if the hour angle of the moon at UT = 0 o'clock is 3.8h,
From the lunar lunar day cycle = 24.7h obtained in Fig. 7, the time at which the hour angle = 0h can be calculated as (24-3.8) x (24.7 / 24) = 20.79 o'clock (20:47).

Referring back to FIG. 6, from the time when the hour angle of the month in Greenwich obtained by the above-described calculation becomes 0:00, the next step S32
Then, the time when the time angle of the moon becomes 0:00 is calculated at a point being clocked or a designated point.

The time t ₂ at which the moon angle becomes 0 o'clock at an arbitrary point is calculated by the following formula.

By substituting the longitude and the time difference of Greenwich of the time point or the designated time point into the above equation, the time when the hour angle of the moon becomes 0 o'clock at that point is obtained, and the time is stored in the register Z ₁₁ of the RAM 16.

For example, in Tokyo at 139.75 degrees east, the time t ₂ when the moon angle is 0 o'clock is the time difference from Tokyo Greenwich (+9 hours).
And the lunar lunar diurnal cycle (24.7
Hour), the following is from UT time (20.79 hour) where hour angle = 0 hour.

When the time at which the moon angle is 0 o'clock is obtained at the arbitrary point by the above calculation, the current time being measured, that is, the moon angle at the time stored in the register Z ₀ is calculated in the next step S33. ,
Store in register S of RAM16.

FIG. 9 is a chart showing a calculation example of the hour angle of the month 11:35 in Tokyo.

The lunar lunar cycle = 24.7 o'clock obtained by the above calculation,
Calculate the time difference of the moon by proportional calculation from the time difference between the time when the time angle of the moon is 0h in Tokyo = 20:12 and the current time you seek = 11:35.

Time difference = 24 x 8.62 / 24.7 = 8.38h. By subtracting this time angle difference from 0h (= 24h), the time angle of the moon at 11:35 = 15.62h can be obtained.

That is, by designating the longitude of the arbitrary point and the time difference from the Greenwich time, the hour angle of the moon at the arbitrary time at the arbitrary point can be easily obtained by the above-described calculation.

If the angular computation time of the month has been completed in this way, then in step S11 of FIG. 5, and resets the flag F ₀ to "0". Then, in the next step S12, it is determined whether or not the flag F ₁ = 1.

If the flag F ₁ = 0, the process proceeds to the display process of step S15, but when the flag F ₁ = 1 is set, that is, when the date is changed after 24 hours have passed, the process proceeds to step S13 to execute the age calculation.

FIG. 10 is a detailed flowchart of the moon age calculation in step S13. First, in step S41, the time stored in the current time register C is converted into Greenwich time based on the time difference from the Greenwich time stored in the register B.

Then, in step S42, the above-mentioned variable t is calculated from the Greenwich time.

Next, in step S43, the visual longitude of the moon is calculated from the variable t obtained in step S42 by the following formula.

Lunar meridian = 481267.9 × t + 218.3 + 6.3 × COS (45 + 4572000 × t) +1.3 × COS (11 + 413300 × t) Similarly, in the next step S44, from the variable T, To calculate.

Sun's visual longitude = 36000.8 × T + 280.5 + 1.9 × COS (268 + 36000 × T) From the difference between the moon's visual longitude and the sun's visual longitude, calculated in the next step S45 Calculate the separation angle. The lunar separation refers to the angle between the sun and the moon as viewed from the earth, and the change in the separation changes the lunar phase. For example, when the angle of departure is 0 °, the new moon, when the angle of departure is 180 °, the full moon, and the angle of departure is 270.
In the case of ゜, it is the month of the last quarter.

Next, in step S46, the age data is calculated from the above-mentioned lunar angle and the cycle of the lunar month and stored in the register R. In this embodiment, the cycle of the lunar month is 29.53 days on average,
The age at the Greenwich time is calculated by proportional calculation from the cycle and the angle of departure of the moon calculated every day. Then, the age of the point is calculated using the time difference between the point and the Greenwich time. That is, the moon age at an arbitrary point can be expressed by the following equation.

FIG. 11 is a chart for explaining the relationship between the angle of departure and the age of the moon obtained by the above-described age calculation and the data and the displayed lunar phase.

If the difference between the visual longitude of the moon and the visual longitude of the sun (angle of separation of the moon) obtained by the above calculation is in the range of 0 ° to 22.5 °, the age of the moon will be 0.0 to 1.8 days depending on the angle of separation. , And the age data obtained at this time is written in the register R of the RAM 16. A moon age of 0.0 to 1.8 days corresponds to a new moon. Similarly, if the moon's angle of departure is in the range of 157.5 ° to 202.5 °, the age data will be any value in the range of 13.0 to 16.6 days depending on the angle of departure at that time. Is written in the register R. A moon age of 13.0 to 16.6 corresponds to a full moon. The same applies when the separation angle is in another angle range,
The relationship between the angle of departure and the age of the moon and the lunar phase calculated by
It becomes as shown in the chart of FIG.

Referring back to FIG. 5, when the moon age calculation is completed, step S14 is performed.
In step S16, the flag F ₁ is reset to 0, and in step S16, a sunrise / sunset calculation for calculating the sunrise / sunset time of the day is executed.

FIG. 12 shows a detailed flowchart of the sunrise / sunset calculation in step S16 of FIG.

However, step S51 is a process of converting the current time to the Greenwich time and storing it in the register Z, as in step S41 of FIG.

In the next step S52, a variable t ₃ for the number of days from January 1 of the year is calculated. If year = YE month = MN day = DA, W = (YE-1900) / 4 F = FRAC (W ) A = INT (1461 × W) B = INT [(MN + 7) / 10] C = INT (1-F) D = INT [0.44 × (MN + 4.4)] Y = A + 31 × MN + DA + (B- 1) × C−B × D, W = (YE-1900) / 4 F = FRAC (W) A = INT (1461 × W) B = INT [(MN + 7) / 10] C = INT (1 -F) D = INT [0.44 × (MN + 4.4)] to the YY = a + 31 + (B -1) is represented by × C-B × D, obtained by the variable t ₃ = Y-YY. However, this variable t ₃ is stored in register Z.

In the next step S53, the variable t is obtained similarly to step S42, and in the next step S54, the time difference is calculated from the variable t ₃ and stored. This time difference KJS is A = (t ₃ −80.5) × 360 ÷ 360.25 B = (t ₃ −4.5) × 360 ÷ 360.25 C = −460.64 × SIN (B) −4.82 × SIN (2 × B) D = If 592.32 x SIN (2 x A) -12.76 x SIN (4 x A), then KJS = C + D (seconds).

In the next step S55, the median time is obtained, and the median time is obtained by the following formula.

Midday = 12-longitude ÷ 15 ° + GMT time difference-time difference ÷ 3600 Here, the data of register D is used as the longitude.
Register B for GMT time difference, step S for equal time difference
The data obtained at 54 is used.

However, in the next step S56, the visual declination of the sun is calculated from the variable t, and this visual declination of the sun is: visual declination = 23.26 x COS (36001 x t + 190) + 0.39 x COS (2 x t + 13 ) + 0.39 × COS (72000 × t + 188) + 0.16 × COS (108002 × t + 211) + 0.01 × COS (72003 × t + 34) + 0.01 × COS (144001 × t + 209)

The next step S57 is to calculate the sunrise / sunrise quotient, which is the latitude ₀ , the sun's visual declination.
_{When set to 1} , A = TAN ( ₀ ) × TAN ( ₁ ) B = −0.017 ÷ COS ( ₀ ) × COS ( ₁ ) Number of sunken numbers = [arcCOS (BA)] ÷ 15 ° .

Then, in the final step S58, the sunrise and sunset times are obtained and stored in the registers J and K of the RAM 16, respectively. The sunrise and sunset times are obtained from the following equations.

Sunrise Time = Midnight-Sunset Count Day Sunset Time = Midnight + Sun Sunset Count Count However, the sunrise / sunset time of the day is calculated in the registers J and K by the sunrise / sunset calculation in step S16 in FIG. After being stored in step S15, the process proceeds to step S15 and a display is made.

FIG. 13 shows a detailed flowchart of the display processing in step S15 of FIG. 5, and FIG. 14 shows changes in the display state on the display unit 2.

In step 60 of FIG. 13, first, it is judged if the value of the mode register M is "0". However, M =
When it is "0", the process proceeds to step 61, and it is determined whether the value of the register N is 0 or not. When N = "0", the next step S6.
2, S63, S64 each month angle data, current time data,
The age data is sent to the display register A, and the data in the register A is transferred to the decoder driver circuit 17 (FIG. 3) in step S65.
And is displayed on the display unit 2. Therefore, the display unit 2
When the register M is "0" in the current timetable mode and the register N is "0", the current time is Monday, June 26, 10:58:50 pm, as shown in Fig. 14A. At the same time, the lunar phase of the day is displayed by the display body 2a ₇ and it is known that it is the moon of the last quarter and the time angle at that time is 15
It can be seen that h (hour), that is, the moon is in the direction of 15h.

In the display state of A in FIG. 14 above, the switch K ₁ ,
When K ₂ and K ₃ are operated, the display is switched to the display shown in B, C and D of FIG. That is, if any of the switches K _{1 to} K ₆ is operated in step S1 of FIG. 5, it is determined that there is a key, and the key processing of step S17 is performed. First
FIG. 5 shows the details of the key processing in step S17 described above.First, it is determined whether or not the key operated in step S100 is the switch K ₁ , and if Yes, the process proceeds to step S101 to register. It is determined whether or not M = “0”. However, when M = “0”, the process proceeds to step S102, where “1” is set in the register M, and the next step S1.
At 03, the current time of the register C is transferred to and stored in the register E. If it is determined in step S101 that M is not "0", the process proceeds to step S104 to determine whether M is "1". If M is "1", M is set to "1" in the next step S105. 2 "is set, and M is not" 1 ", M is" 2 ".
As a result, M is set to “0” in step S106. That is, the value of M is "0" every time the switch K ₁ is operated.
It changes with "1""2""0" .... However, in the display process of FIG. 13, when M = “1”, the process proceeds from step S60 to step S66, where it is determined whether M = “1” and the process proceeds to step S67. Thus, the flag F ₂ in step S67 is discriminated whether zero or not F ₂
= “0”, in step S68, the contents of register E,
That is, when M = “0” and the switch K ₁ is operated, only the contents of the month, the day, the day of the week, and the year among the current time data transferred to the register E in step S103 are sent to the display register A, Displayed in the next step S65. Therefore,
The display contents when M = “1” are as shown in FIG. 14B. Further, when it is determined in step S66 in FIG. 13 that M is not "1", that is, when M is "2", step S69.
Although not shown in the figure, the data to be displayed is sent to the register A depending on whether the flag F _{2 is} "1" or "0", which is not shown, and step S6
Displayed at 5. For example, when F ₂ = “0”, as shown in E of FIG. 14, the month, day, day of the week, and year data of the register E are displayed.

Step when switch K ₂ is operated in FIG.
It is detected in S107, and it is determined in the next step S108 whether M = “0”. M = time of "0" is the operation of the switch K ₂ at the current time display mode, the next step S109, S1
11, the value of the register N is determined in S113. Register N =
When it is "0", the switch K ₂ is operated in the state of A in FIG. 14, and the process proceeds to step S110 to register N.
Is set to "1", and a process of designating the second digit as a corrected digit is performed. When N = “1”, the process proceeds from step S111 to step S112, and the register L is set to “0”.
Is set and "2" is set in the register N. Further, when the register N = “2”, the process proceeds from step S113 to step S114, and the same processing as steps S10, S13, S16 of FIG. Although not shown in FIG. 15, N is set to "0".

As described above, the switch K ₂ is operated when M = “0”,
When the value of the register N changes from "0" to "1" or "2", the display contents are switched as follows. That is, in the display process of FIG. 13, since M = “0”, the process proceeds from step S60 to step S61, and it is further determined in step S70 whether N = “3” and the next step S60.
At 71, N = “1” is determined. However, when N = "1", the process proceeds to step S72, the current time data of the register C is sent to the display register A, and the correction target digit is flushed in the next step S73. Therefore, N = “1”
In the case of, as shown in FIG. 14C, the time adjustment mode is entered and the current time can be adjusted. Further, when the switch S ₂ is operated in the state of N = “1”, N is set in step S112.
= "2", and the time difference / longitude / latitude setting mode of F in Fig. 14 is entered. However, in the display process of FIG. 13, the process proceeds from step S71 to steps S74 and S75, and the value of the register L is discriminated. However, when the register L = 0, the process proceeds from step S74 to step S76, and the GMT character data, the time difference data of the register B and the hour, minute and second data of the register C are sent to the register A, and the correction point (L =
When it is 0, GMT characters and time difference data) are blinked. Therefore, the display shown in G of FIG. 16 is made. The value of the register L is changed by the switch K ₅ as will be described later. When L = "1", the LO character indicating the longitude in step S78, the longitude data of the register D, the latitude data of the register H and n and The w character data is sent to the register A, and the LO. character and longitude data, which are the correction points, are blinked. When L = “2”, the LA character, the registers D and H, and the character data n and w are sent to the register A in step S79, and the process proceeds to the next step S77. Therefore, N = “2”
When the register L is "1" or "2" in FIG. 16, the display as shown in FIG. Incidentally, the above-mentioned FIG. 16G, H,
In the display of I, the data at the blinking point can be corrected by the switch K ₃
It is executed by the operation of. This will be described later. When the switch K ₂ is operated in the state of N = “2”, the mode returns to the current time display mode of N = “0” shown in A of FIG. 14 or FIG. However, at this time, the steps in Fig. 15
In S114, the time angle of the moon, the age of the moon, and the sunrise / sunset time are calculated based on the corrected current time, time difference, longitude, and latitude data, so in the display mode of N = "0", the corrected data Based on the time angle of the moon, the lunar phase is displayed.

Next, the operation of the switch K ₃ is determined in step S115 of FIG. 15, and the process proceeds to the next step S116. In this step S116, it is determined whether or not M = “0”. If the current time display mode is M = “0”, the following steps S117 and S1 are performed.
At 18 it is determined whether N = “0” and N = “3” respectively. When N = “0”, N is set to “3”, N at step S119.
If "3", "0" is set to N in step S120. However, when N = “3”, this is determined in step S70 in the display processing of FIG. 13, and in the next step S78, the sunrise and sunset mark display bodies 2b and 2b of FIG. 2 are displayed.
"1" signal to display is set in register A,
In the next step S79, the sunrise time, the sunset time, and the moon age data stored in the registers J, K, and R respectively are transferred to the register A.

Therefore, when the switch K ₃ is operated in the display state of M = “0” and N = “0” shown in A of FIG. 14, N = “3” at step S119 of FIG. 15, and N = “ When it becomes "3", in steps S78 and S79 of FIG. 13, the process of displaying the sunrise, the sunset mark display bodies 2b and 2b, the sunrise time, the sunset time, and the moon age data are performed, respectively, as shown in D of FIG. , Sunrise time 5:25, sunset time 8
The time 35 minutes is displayed together with the mark display 2b, and the age data 22.4 days, the lunar phase, etc. are displayed. When the switch S ₃ is operated in the display state of FIG. 14D, N = “0” is set in step S120 of FIG. 15, so the display returns to the current time display shown in A of FIG.

When N is not "3" in step S118 of FIG. 15, N is "1" or "2", that is, C of FIG.
Current time correction mode or time difference of F in Fig. 14 /
It is regarded as the longitude / latitude setting mode, and the next step S121
If it is the correction mode of the current time, the digit to be corrected, time difference /
In the longitude / latitude setting mode, processing for sequentially correcting or setting data in units of time difference, longitude, or latitude designated by the register L is performed.

Further, when it is determined in step S116 in FIG. 15 that M is not "0", it is considered that M is "1" or "2", the process proceeds to step S122, and it is determined whether or not F ₂ = "0". Is determined. However, when F ₂ = 0, the next step S123
Then, the process of sequentially advancing the date of the current time data of the register C transferred to the register E is performed. That is, M = “1”
In the mode of (1), the best fishing time display mode (G) of FIG. 14 shows the time when the fish is most caught on the current date transferred to the register E or the desired date obtained by correcting this date. F ₂ = “1”) can be displayed, and in the sunrise / sunset time display mode of M = “2”, the sunrise time and sunset time on the current date or the desired date can be similarly set to H in FIG. Can be displayed in the sunrise and sunset time display mode (F ₂ = “1”), and in step S123 of FIG.
The date in the register E is updated to obtain the desired date. 14I is a display example in which the date data of the current time stored in the register E shown in FIG. 14B, June 26, 1989, is advanced to June 30, 1989 by operating the switch K _3. J in FIG. 14 shows a display example similarly advanced on July 1, 1989. In addition, these display processing,
When M = "1", step S68 in FIG. 13, M =
If the value is "2", it is performed in step S69. Then, the processing obtained by calculating the fishing best time or the sunrise / sunset time based on the date data of the register E is executed by the operation of the switch K ₄ , and the processing will be described below.

The operation of the switch K ₄ is determined in step S124 of FIG. 15, and in the next step S125, it is determined whether M = “1”. When M = “1”, F ₂ = “0” in the next step S126.
It is determined whether or not, that is, whether or not the display state is B or I in FIG. However, when F ₂ = “0”, the process proceeds to the next steps S127 and S128, and age calculation processing and moon angle calculation processing are performed. The age calculation process of step S127 is almost the same as that shown in FIG. 10, except that the calculation is performed based on the current time of register C in FIG. 10, but in step S127, the time data of register E is calculated. That is,
A point which is performed based on any time data set by the current time data or switch K _3, old data is not the register R obtained by the calculation result in step S46 in FIG. 10, the point that is stored in the register U Only different. In addition, the time angle calculation of the moon in step S128 is
The steps are similar to steps S21 to S32 in FIG. 6, except that the steps are performed based on the register E as described above. Further, in step S32, when the time when the hour angle becomes 0 o'clock is obtained, this data is stored in the register W. In the next step S129, the hour angle is set to 6 in the same manner.
Find the times that will be 12:00, 18:00. Then, at corners 0 when obtained in the next step S130 in the step S128,129, 6:00, 12:00, and stored the time data of 18 o'clock respectively register T ₀ through T _3. Furthermore, in the next step S131,
The age data obtained at step S127 and 0 o'clock, 6 o'clock, 12 o'clock
Data indicating the fishing condition of the fish is calculated from the hour angle data of 18:00, and the data corresponding to the hour angles of 0 hour, 6 hour, 6 hour, 12 hour, and 18 hour are stored in the registers Q _{0 to} Q ₃ , respectively.

FIG. 17 illustrates the fish mark number data calculation processing in step S131 described above. For example, when the moon angle is 0:00 or 12:00, the age data is 0.0 to 1.8 or 2 shown in FIG.
In the case of a new moon of 7.7 to 29.5 or a full moon of 13.0 to 16.0, assuming that it is the time when the fish can be caught best, the data for displaying all four fish mark display bodies 2f is stored in the registers Q ₀ , Q ₂
To memorize. If the age of the moon is the data indicating the moon of the upper or lower string, it is assumed that it is the time when the fish can be caught next, and the data for displaying three of the four fish mark display bodies 2f are stored in the register Q ₀ , It is something to be memorized in Q ₂ .
Similarly, display data corresponding to the moon angle and age data as shown in FIG. 17 are stored in the registers Q _{0 to} Q ₃ , respectively. However, when the process of step S131 in FIG. 15 is completed, the process proceeds to step S132, and the flag F _{2 is set} to "1".
Is set. By setting the flag F ₂ to "1" in step S132, the display on the display unit 26 changes from B or I in FIG. 14 to the fishing best time display mode in G in FIG. That is, when M = “1” and F ₂ = “1”, in the display process of FIG. 13, the process proceeds from steps S66, S67 to steps S80, 81, 82, and the value of the register P is discriminated. However, when P = "0", the next step S83
Then, of the 25 time-angle display bodies 2c of the display unit 2, the data for displaying the display body 2c corresponding to the time angle 0 is set in the register A, and in the next step S84, in the step S131 of FIG. 15 described above. The fishing condition data of the fish at the time angle 0 o'clock which is calculated and stored in the register Q ₀ is set in the register A,
Further, in the next step S85, the age data stored in the register U, the date data in the register E, the time data at 0 o'clock in the register T ₀ , and the data of the numerical value “2” are stored in the register A.
Is set to Then, in the next step S86, data indicating which of the moon phase indicators 2a to 2a ₉ is to be displayed is set in the register A from the age data in the register U, and the data set in these registers A are displayed in step A65. It is displayed on the part 2.

FIG. 18 shows a change in the display state in the fishing best time display mode in which M = “1” and F ₂ = “1”. Thus, the value of the register P is as described below, which changes to "0" to "3" by operating the switches K _5, when P = "0", as shown in B of FIG. 18,
On June 26th, the time when the moon angle is 0 o'clock is 6:55, the age is 22.4, the lunar phase is the last month of the month, and the fishing condition is the second best (four fish mark display It is the best that all 2f lights up, and since 3 are displayed in the above display, 2
Th) is displayed.

When P = “1”, the process proceeds from step S81 to steps S87, 88 and 89, and when P = “2”, the process proceeds to step S8.
When 2, 90, 91, 92, P = "3", steps S93, 94,
95, respectively, and the data to be displayed at the time angles of 6 o'clock, 12 o'clock, and 18 o'clock are set in the register A, respectively. That is, the data for displaying the corresponding hour-angle indicator 2c is set in steps
Set in S87, 90, 93, the fishing condition data of the fish at that time are set in steps S88, 91, 94, respectively, and age data, date data, time data corresponding to each time angle, and number data indicating the display order Steps S89, 92, 95
Are set in the register A respectively. Therefore, as shown in C, D, and A of FIG. 18, the display unit 2 displays various data when the time angles are 6:00, 12:00, and 18:00, respectively.

In FIG. 15, when it is determined in step S125 that M is not "1", the process proceeds to step S133, where M =
It is determined whether or not it is "2". M = F ₂ = whether "0" in step S134 when the "2" is determined, F ₂ = time of "0", the flow proceeds to the next step S135 and S136, age calculation, sunrise / sunset calculation is performed It This age calculation and sunrise / sunset calculation are the same as those shown in FIGS. 10 and 12, respectively. The difference is the data stored in the register E (current time data or data set by the switch K ₃ ). And the point that the calculation result data is stored in the register U, the register X, and the register Y, respectively. However, since F ₂ is set to "1" in the next step S132,
In step S69 of the display process shown in FIG. 13, it is determined whether or not F ₂ is "1", and when it is "1", the above registers U, X,
Display the data stored in Y. Therefore, H in FIG.
In, the sunrise time, the sunset time, the age data, the date, the moon phase, and the sunrise / sunset mark display bodies 2b, 2b on the day stored in the register E are displayed.
This display is similar to D in FIG.

Further, in steps S126 and S134 of FIG. 15, F ₂ = “0”, respectively.
Not, that is, when it is determined that F ₂ = “1”, step
Proceed to S137, F ₂ is set to “0”. As a result, in the display unit 2, from the display state of FIGS.
Returns to the display state of.

The operation of the switch K ₅ is determined in step S138 in FIG. When the operation of the switch K ₅ is determined in this step S137, the process proceeds to steps S139 and S140, whether M = “0”, N =
It is determined whether or not it is "1", and if M = "0" and N = "1", in the next step S141, a process for selecting the digit to be modified is performed. That is, when the switch K ₅ is operated in the time correction mode of C in FIG. 14, the current time correction unit is progressively selected from seconds to minutes and minutes to hours. When it is determined in step S140 that N is not "1", it is determined in step S142 whether N is "2". When N is "2", the register L is stored in the next step S143.
The value of is sequentially advanced. Therefore, F of FIG.
