(B) Operation in clock mode Now, assuming that the value of the mode register M is 0 and the clock mode is set, there is no switch operation in step S1 of FIG. 3 unless the switch is operated. Judge,
In step S10, it is determined that the value of the switch operation flag KF is not 1, and in step S5 it is determined that the value of the flag FS is not 1, and the process proceeds to step S8, that is, the display process of FIG. Then, in step S160, it is determined that the value of the mode register M is 0 and the watch mode is set, and in step S161, the date and day of the week from the time / date counting circuit 4 are displayed on the digital display portion 8i of the display portion 8. In the next step S162, the second digit of the current time from the time / date counting circuit 4 is set to the second hand position instruction register N.
In step S163, the minute digit of the current time is set in the minute hand position instruction register NM, and in step S164, the digit of the current time is set in the hour hand position instruction register NH. Then step S16
5, that is, the pointer movement processing of FIG. In this pointer movement process, first, in step S220, it is determined whether the value of the second hand position instruction register NS is equal to the value of the second hand position register GS. If they are equal, the process proceeds to step S225, but they are equal. If not, a signal is sent to the drive circuit 11 to advance the second hand 14 by one step, and in step S222, the value of the second hand position register GS is set to 1 in order to store that the second hand 14 is advanced by one step.
If the value of the second hand position register GS has reached 60 in the above process, it is determined in step S223, and if not 60, step S22
If it is 60, proceed to step S224.
The value of the second hand position register GS is reset to 0 with.

As described above, steps S220 to S2
After executing the movement processing of the second hand 14 in the processing of 24, the processing proceeds to the minute hand movement processing of step S225. This step S
In 225, the movement processing of the minute hand 18 is executed by substantially the same processing as the processing of steps S220 to S224 (that is, it is determined whether the step value of the minute hand position register GM and the value of the minute hand position instruction register NM are not equal, When they are not equal, a signal is sent to the drive circuit 15 to send the minute hand 18
Is advanced by one step, and the process of increasing the value of the minute hand position register GM by 1 is executed. After the processing of step S225 is completed, step S
Proceeding to the hour hand movement processing of 226, the second hand 14, minute hand 18
The hour hand 22 is moved in substantially the same manner as the movement processing of the hour hand (in this case, the hour hand position register GH and the hour hand position instruction register N).
The processing will be executed using H).

After moving each pointer by one step as described above, the pointer moving process of FIG. 10, that is, the process of step S165 of FIG. 9 is completed, and the display process of FIG. 9, that is, the process of step S8 of FIG. After that, the process returns to step S1 and the process according to the flowchart of FIG. 3 is repeated. Thus, for example, assuming that it is Wednesday, September 30, at 10:08:35, the display on the pointer display unit and the display unit 8 is as shown in FIG.

In addition, in this watch mode, when a switch other than the switch S3, which is a mode switch, is operated, it is detected in step S1 of FIG. 3, and the value of the switch operation flag KF is set to 0 in step S2. Then, the value of the switch operation flag KF is set to 1 in step S3, and the process proceeds to step S4, that is, the switch process of FIG. Then, in step S25, it is determined that the switch S3 is not operated, and it is determined in step S25.
In step 35, it is determined that the value of the mode register M is 0 and the watch mode is set. In step S36, the watch mode switch process, for example, the process of advancing the minute hand 18 to adjust the time is executed. After executing the switch process of step S4 of FIG. 3 as described above, the process proceeds to the display process of step S8 via step S5, and the same process as described above is executed.

(B) Operation in the plan mode In this embodiment, when the total traveling distance from the start point is measured while actually driving (that is,
In the case of using in the drive mode), in principle, a plurality of check points are set on the drive course in the plan mode, and data relating to each check point, that is, a distance between the check points is set. To change from the timepiece mode to the plan mode, as shown in FIG. 12, the switch S3 is operated to first set the drive mode, and then the switch S3 is set.
Operate again to enter the plan mode. In this case, when the switch S3 is operated for the first time, it is detected in step S25 of FIG. 4, and the drive mode is set by setting the value of the mode register M to 1 in step S27 through step S26, and then the switch S3 is operated. In the second operation, similarly to the above, it is detected in step S25, and it is determined in step S26 that the value of the mode register M is not already 0, and the process proceeds to step S28. In this step, the value of the mode register M is 1 and it is determined that the drive mode is set. Then, the process proceeds to step S29, the mode register M is set to 2 and the plan mode is set, and in step S30, the next plan is set. The value of the register P is set to 1 in preparation for the setting operation.

As described above, after setting the value of the mode register M to 2 in the plan mode in the switch processing of step S4 of FIG. 4, that is, step S4 of FIG.
After step 5, the process proceeds to step S8, that is, the display process of FIG. Then, in this display process, steps S160 and S
After 166, the process proceeds to step S200, determines that the value of the register Q is 0, proceeds to step S201, and determines whether the value of the set checkpoint number register MP is not 0, that is, the checkpoint data part CP is set to the previous drive. Check if the data remains. When the value of the set checkpoint number register MP is 0 and no data remains in the checkpoint data portion CP, the process directly proceeds from step S201 to step S163.
If the value of the set checkpoint number register MP is not 0 and data remains in the checkpoint data section CP, the process proceeds to step S201 to step S20.
Go to 2. In this step S202, the checkpoint designated by the register P, that is, the first checkpoint in this case
Distance of checkpoint (as described above, becomes a checkpoint at which plan data is set in the row of the row address CP1 in the checkpoint data portion CP) (as described above,
The distance set as the distance from the start point to the first check point) is displayed on the digital display unit 8 of the display unit 8.
Display on i. In the following step S203, the plan mark display body 8g of the display unit 8 is lit to indicate that it is in the plan mode, and in step S204, it corresponds to the speed of the row of the row address CP1 of the checkpoint data section CP. The value is set in the second hand position instruction register NS, and after that, the process proceeds to step S163. Then, in step S163, in the same manner as described above, the minute hand position instruction register N
A value corresponding to the digit of the minute of the current time is set in M, a value corresponding to the digit of the hour of the current time is set in step S164, and thereafter, the process proceeds to step S165, that is, the pointer movement processing of FIG. Then, in this pointer movement process, when it is necessary to advance any one of the pointers, as described above, the pointer is advanced by one step.

As described above, when the display process of step S8 of FIG. 3 is completed, the process returns to step S1 and the process according to the flowchart of FIG. 3 is repeated, and each of the pointers indicates the indicated position. Will be reached. In this embodiment, the switch operation flag KF is used so that the switch processing of step S4 is performed only once for one switch operation regardless of the length of the operation time (steps S2 and S3). , S10, S11). Therefore, when the switch operation is performed as described above and the switch processing in step S4, the display processing in step S8, and the like are executed and the processing returns to step S1, the value of the switch operation flag KF is set to 0 in step S11 through step S10. Then, the process proceeds to step S5, and the process of step S4 is not performed. Thus, at 10:08 at present, when the distance stored in the row address CP1 of the checkpoint data portion CP is 1 km and the speed is 60 km / h, the pointer display portion or the like in FIG. A display as shown in a of FIG. 13 is made.

As described above, after the plan mode is set (that is, after the state of FIG. 13a), the plan data can be actually set in the checkpoint data portion CP as shown in FIG. Switch S2 is operated. At this time, the operation is detected in step S40 of FIG. 5, the process proceeds to step S41, it is determined that the value of the register Q is 0, and then the value of the register Q is set to 1 in step S42 to set the plan setting state. Then, in the subsequent step S43, the value of the register K is set to 0, and in step S44, the value of the register P is set to 1, and the first checkpoint is selected (that is, the row of the row address CP1 of the checkpoint data portion CP is selected).

In the subsequent display process (FIG. 9), step S2
At 00, it is determined that the value of the register Q is not already 0, the process proceeds to step S205, and the plan mark display 8
g, the set mark display body 8e and the point number display body 8h set by the register P, that is, the point number display body 8h of numeral 1 is lit and displayed. Then step S2
In 06, the speed already set in the row designated by the register P of the checkpoint data section CP, that is, the row of the row address CP1 is set in the second hand position instruction register NS, and in step S207, the value of the register K is not 3 but 0. Then, the process advances to step S209 to display the line distance of the line address CP1 on the digital display portion 8i, and then the process proceeds to steps S163 to S165. When the row distance of the row address CP1 is 1 km, the display on the display unit 8 is as shown in FIG. 13c.

After setting the above state, in order to set the distance (the distance from the start point to the first check point as described above) in the row of the row address CP1 designated by the register P, first, referring to FIG. The switch S5 is operated as shown in. At this time, the operation is detected in step S65 of FIG. 5, and the value of the register K is incremented by 1 by 1 in the next step S66. As a result, the state shown in d of FIG. 13, that is, the distance can be set in units of 1 km. To actually set the distance, the switch S1 or S4 is operated as shown in FIG. For example, each time the switch S1 is operated, it is detected in step S70 of FIG. 5 each time, and it is determined in step S71 that the value of the register K is 1, and step S7
5, the distance is increased by 1 km (when the switch S4 is operated, the step S7 is performed).
Proceed to 9 and shorten the distance by 1 km. The same applies to the following setting operations. When the switch S4 is operated, a negative value is added, which is the opposite of when the switch S1 is operated). After setting the portion of 1 km or more of the distance as described above, the portion of 1 km or less of the distance (for example, 0.8 km when the distance is 20.8 km).
13), the switch S5 is first operated as shown in FIG. Also in this case, the operation is detected in step S65, and the value of the register K is set to 1 in step S66.
Only 2 is set. As a result, the state of e in FIG. 13, that is, the state in which the distance of 1 km or less can be set can be set. When actually setting the portion of 1 Km or less, as shown in e of FIG.
Or, operate S4. For example, each time the switch S1 is operated, the switch S1 is operated at step S7 of FIG.
When it is detected as 0, the process proceeds to step S76 through step S71, and the distance is increased by 0.01 km.
Then, in the display process, the set distance is displayed on the digital display unit 8i (step S209 in FIG. 9). For example, when the set distance is 50 km, the display on the digital display portion 8i is as shown in e of FIG.

After the distance relating to the first checkpoint is set in the row of the row address CP1 as described above, the speed for traveling the above distance is set in the row. In this case, first, the switch S5 is operated, whereby the value of the register K becomes 3 in the same manner as described above (steps S65 to S67 in FIG. 5). As a result, the traveling speed is 2 km / h.
The unit can be set. Then, to actually set the speed, the switch S1 or S4 is operated. For example, each time the switch S1 is operated, it is detected each time in step S70 of FIG. 5, the process proceeds to step S77 via step S71, the speed is increased by 2 Km / h, and the subsequent step S78. Then, the time required for traveling from the start point to the first check point is calculated from the distance and the speed already set, and is set to the row address CP1. Then, in the subsequent display processing (FIG. 9), the plan mark display 8g, the set mark display 8e and the point number display 8h of numeral 1 are lit up and displayed in step S205, and in step S206 the row address CP1 is set as described above. The step value corresponding to the speed set in the line is set in the second hand position instruction register NS, it is determined in step S207 that the value of the register K is 3, and the process proceeds to step S208 to calculate as described above. Then, the time set in the above line is displayed on the digital display portion 8i. After that, the aforementioned steps S163 to S163
Although the process proceeds to step 165, in the pointer movement process of step S165, the speed is displayed by the second hand 14 according to the step value of the second hand position instruction register NS.
For example, when the speed is 50 km / h and the above time is 1 hour, the display of the second hand display portion and the display portion 8 is f in FIG.
It becomes something like.

As described above, the distance, speed, and time from the start point to the first checkpoint, that is, the plan data relating to the first checkpoint, are stored in the row address C.
After setting in the row of P1, the distance, speed, time between the first check point and the second check point, that is, in order to set the plan data related to the second check point in the row of the row address CP2, The switch S5 is operated as shown in. At this time, the operation is detected in step S65 of FIG. 5, the process proceeds to step S66, the value of the register K is increased by 1 by 4, and it is determined in the next step S67 that the value of the register K exceeds 3. Then, the process proceeds to step S68, and the value of the register K is set to 0. As a result, the state returns to the state of c in FIG. After that, in order to set the value of the register P to 2 and specify the row of the row address CP2,
The switch S1 is operated. At this time, the operation is detected in step S70, and after step S71, step S72.
Then, the value of the register P is incremented by 1 to 2, and the row of the row address CP2 is designated.

After setting the value of the register P to 2 as described above, the distance, speed, and time relating to the second checkpoint are set in the row of the row address CP2 in the same manner as described above. In addition, after setting the distance related to the second check point in the row of the row address CP2, the row addresses CP3, CP4, CP5,
The distances related to the third, fourth, fifth and sixth checkpoints will be set in the respective rows of CP6.

After setting the plan data for all checkpoints in the checkpoint data section CP as described above, if the switch S5 is operated to set the value of the register K to 0 and the switch S1 is operated, After steps S70 and S71 of FIG.
Is increased by 1 by 7, and it is determined in the next step S73 that the value of the register P exceeds 6, and the value of the register P is returned to 1 in step S74. This again
The row having the row address CP1 is selected, and the distance and the like previously set in this row can be corrected.

After setting the plan data relating to each checkpoint in each row of the checkpoint data section CP as described above, the plan setting state is canceled as shown in FIG.
The switch S2 is operated as shown in FIG. At this time, the operation is detected in step S40 of FIG.
In 41, it is judged that the value of the register Q is not 0 but 1 and then the process proceeds to step S45 to set the value of the register Q to 0. Then, in the next step S46, the number of checkpoints in which the plan data is set in the plan setting state (that is, the number of rows in which the data is set among the six rows of the checkpoint data section CP) is set. After being set in the register MP, it is determined in the next step S47 whether or not the number of check points is 0. If not, the process proceeds to step S48 to set the value of the distance register CL to 1. Then, in the subsequent display processing (FIG. 9), steps S200 to S204 and S163 to S1 are performed.
The processing of 65 is executed in the same manner as described above, and the display state as shown in FIG.

In the above state, the data relating to each checkpoint set in the checkpoint data section CP can be sequentially displayed and confirmed on the display section 8 or the like. In this case, the switch S1 is operated, but at this time, each time the operation is performed, the switch S1 is changed to the step S in FIG.
51, the value of the distance register CL is determined to be 1 in step S52, the process proceeds to steps S53 to S55, and the value of the register P is changed from 1 to the value of the set checkpoint number register MP. For each click, the size is sequentially increased by one, and in the display process, the processes of steps S200 to S204 and S163 to S165 of FIG. 9 are executed in the same manner as described above, and are sequentially stored in each row of the checkpoint data portion CP. The data relating to each check point is displayed on the display unit 8 or the like for each check point.

By the way, as described above, the data relating to each checkpoint is set in the checkpoint data portion CP, and then the plan setting state is released and the above-mentioned FIG.
After returning to the state of a, for example, in the case of this drive, when the plan is changed to the plan-less state described later, it is necessary to delete all the above-mentioned data set in the checkpoint data section CP. However, at this time, the switch S4 is operated as shown in FIG. At this time, the operation is detected in step S60 of FIG.
In step S62, the value of the distance register CL is set to 0, and the value of the set checkpoint number register MP is set to 0.
And Then, in the subsequent display processing (FIG. 9), step S
The process proceeds from step 200 to step S201, determines that the value of the set checkpoint number register MP is 0, and directly proceeds to the process of steps S163 to S165. As a result, no data is displayed on the display unit 8 as shown in b of FIG.

(C) Operation in drive mode For example, in the plan mode, as shown in (1) of FIG. 15, five check points (goal points) are provided between the start point (Iruma) and the goal point (Kikugawa). Is set as 6 check points), and the distance, speed, and time related to each check point are as shown in the figure, and these are set in the check point data section CP. To switch the mode from the mode register M value of 2) to the drive mode (mode register M value of 1), the switch S3 is operated twice as shown in FIG. In this case, the switch S3
For the first operation of step S25 of FIG.
Then, it is detected, the value of the mode register M is set to 0 in step S33 through steps S26, S28, S31 to set the timepiece mode, and the second operation of the switch S3 is performed in step S25 of FIG. When this is detected, the process proceeds to step S27 through step S26 and the value of the mode register M is set to 1 to set the drive mode.
Then, in the subsequent display processing, steps S160 and S16
6, the distance of the total distance register T (in this case, it is 0 before the start) is displayed on the digital display unit 8i in step S168 through step S167.
At 69, the drive mark display 8f is lit to indicate that the drive mode is set, and step S16 is performed.
Then, the process proceeds to 3 to S165. Thus, the display on the pointer display portion and the display portion 8 is as shown in FIG. 12b, that is, in FIG. 14a.

After the above state, the switch S1 is operated to start the drive. At this time, it is detected in step S1 of FIG. 3 that the operation is performed, and step S2
In step S3, it is determined that the value of the switch operation flag KF is 0, the value of the switch operation flag KF is set to 1, and the process proceeds to step S4, that is, the switch process of FIG. Then, through steps S25 and S35, the process proceeds to step S37, that is, the drive mode switch process of FIG. Then, in step S85, it is determined that the value of the register N is 0 and it is in the reset state, and the next step S8
In step 6, it is determined that the switch S1 has been operated, and in the next step S87, it is determined that the value of the setting data flag CL is 1, and the flow proceeds to step S88 to set the value of the register N to 1 It is memorized that the operation in the existence state is started. Next, in step S89, the value of the flag FS is set to 1, and in step S90, a clear signal is sent to the timer 7 to clear the counting time, and then step S91.
And the set signal is sent to the RS flip-flop 6 to start counting the elapsed time by the timer 7 (in this case, the RS flip-flop 6 is set, and the output of the RS flip-flop 6 opens the AND gate 5; The 1 Hz signal from the frequency dividing circuit 3 is the AND gate 5
Will be sent to the timer 7 via). In the following step S92, the value of the register L is set to 0, and the digital display unit 8i is instructed to display the total distance of the total distance register T. Then, in step S93, the value of the passage check point number register R is set to 0, and
At 94, the value of the hour hand position instruction register NH is set to 0, and at step S95, the value of the minute hand position instruction register NM is set to 0. After that, the process proceeds to the estimated arrival time calculation storage process of step S96. In this step S96, the current time from the time / date counting circuit 4 and the checkpoint data part CP
Calculate the estimated time of arrival at each checkpoint from the time related to each checkpoint stored in each row of
Checkpoint data section C corresponding to each of them
Store in row P.

After the step S4 of FIG. 3, that is, the switch process is completed as described above, the process proceeds to step S5.
The value of the flag FS is 1, it is determined that the timer 7 has already started measuring the elapsed time, and in the next step S6, it is determined whether the 1 Hz signal from the frequency dividing circuit 3 is present. When the 1 Hz signal is not received, the process proceeds to step S8, that is, the display process of FIG. 9, and steps S160 and S1.
After 66 and S167, the routine proceeds to step S170, where it is determined that the value of the register N is 1, it is determined at step S171 that the value of the register L is 0, and the routine proceeds to step S172. In this step S172, the total distance of the total distance register T (in this case, it is 0 km because it is right after the start) is displayed on the digital display unit 8i, and in the next step S173, the drive mark display body 8f and the trip mark are displayed. The body 8c, the point number display body 8h of a value (that is, 1) obtained by adding 1 to the value of the passing checkpoint number register R is lit and displayed, and it is in the drive mode, and the drive has already been started. Indicates that you are driving toward. Then, in the next step S174, the speed relating to the first checkpoint (that is, the speed stored in the row address CP1 of the checkpoint data portion CP) is set in the second hand position instruction register NS, and the following step S17
In 5, the value of the distance register CT (0 in this case) is the first
Judge that the distance is smaller than the checkpoint distance,
In step S176, the distance between the check points is multiplied by 60, that is, the first point, in order to display the progress (running) degree between the check points by the minute hand 18 that makes one revolution in 60 steps. It is divided by the distance related to, the integer part of the quotient is taken, and this is set in the minute hand position instruction register NM. After that, step S
Proceeding to step 165, the same processing as described above is executed, and the speed related to the first check point, that is, 40 km / h, is set by the second hand 14.
(Refer to (1) of FIG. 15) is displayed, and the degree of progress between checkpoints (in this case, immediately after the start, 0) is displayed by the minute hand 18.

After the display process of step S8 in FIG. 3 is completed as described above, the process returns to step S1 to determine whether the operation of the switch S1 at the start is continued. If the operation is continued (the time from the operation of the switch S1 at the start to the stop of this operation, that is, the operation time of the human being, the operation of the switch S1 at the start is detected in step S1 and a series of processing is executed. The time until the display process of step S8 ends and the process returns to step S1 is shorter, so such a state can occur sufficiently.) In step S2, the value of the switch operation flag KF is 0.
Rather, it judges that it is 1, and step S1
In step 5, it is determined that the switch S1 is operated, and in step S16, it is determined that 2 seconds or more have not elapsed since the operation of the switch S1 was started (human switch operation). 2 even though the speed is slow
No operation is performed for a second), the display process of step S8 is executed through step S5, and the process returns to step S1.

Operation as described above (switches S1, S2, S
15, S16, S5, S8, S1) is performed several times, and when the operation of the switch S1 is stopped, it is detected when the process returns to step S1 as described above. Go to step S10. This step S1
When it is 0, it is determined that the value of the switch operation flag KF is 1, and the process proceeds to step S11. The value of the switch operation flag KF is returned to 0, and the process proceeds to step S5 and the subsequent steps. Also, after that, the process returns to step S1 and step S
When the process proceeds to step 10, it is determined that the value of the switch operation flag KF is already 0 instead of 1, and the process directly proceeds from step S10 to step S5 and thereafter. After that, the same processing is repeated until the 1 Hz signal is sent from the frequency dividing circuit 3.

When the above 1 Hz signal is sent while the above-described operation is repeated, the step S6 is executed.
In step S7, that is, the distance calculation process of FIG. 7 is performed. In the process, first, step S145.
Then, the value of the register N is 1 and it is confirmed that the plan is present, and the process proceeds to the next step S146.
Then, in step S146, the speed corresponding to the checkpoint designated by the value obtained by adding 1 to the value of the passing checkpoint number register R, that is, the first checkpoint (the row address C of the checkpoint data portion CP as described above).
The distance traveled in 1 second is calculated from the speed set in the line P1), and in the next step S147, the distance of the distance register CT (in this case, 0 immediately after the start) is traveled in the above 1 second. Only long. Further, in the next step S148, the distance of the total distance register T (which is also 0 immediately after the start is set to 0) is set to be long by the distance advanced for 1 second.

After the distance calculation process of step S7 of FIG. 7 or FIG. 3 is completed, the process proceeds to step S8, that is, the display process of FIG. 9, and steps S160, S166, and S16.
It is judged in step S171 that the value of the register L is 0 and the display of the total distance of the total distance register T is instructed in step S171. Then, in step S172, the total distance of the total distance register T is digitally displayed. In step S173, the drive mark display body 8f, the trip mark display body 8c, and the point number display body 8h having a value obtained by adding 1 to the value of the pass check point number register R (that is, the numerical value 1) are lit up and displayed. In step S174, the speed related to the first check point is set in the second hand position instruction register NS, and the next step S1
Proceed to 75. Then, in step S175, it is determined that the distance in the distance register CT is less than or equal to the distance related to the first checkpoint, and in the next step S176, the value obtained by multiplying the distance in the distance register CT by 60 is divided by the distance related to the first checkpoint. The integer part of the quotient (that is, the degree of progress of the drive up to the first check point) is set in the minute hand position instruction register NM. In the subsequent pointer movement processing of step S165, the speed related to the first check point is displayed by the second hand 14 by the same processing as described above, and the minute hand 18
Displays the progress of the drive up to the first checkpoint.

After that, unless the switch is operated, the processes of steps S1, S10, S5 to S8 and S1 in FIG. 3 are repeated, and the 1 Hz signal is detected every one second, and the distance register CT and the total distance register T are detected. The distance is made long, and the distances of the distance register CT and the total distance register T are displayed on the data display unit 8 and the pointer display unit. For example, when the total distance of the total distance register T is 5.32 Km, the display on the display unit 8 is as shown in b of FIG.

When the drive is started as described above and the momentary total distance is displayed on the digital display section 8i, the time at which each checkpoint arrives (that is, stored in each row of the checkpoint data section CP). In this case, the switch S4 is operated as shown in FIG. 14 in order to confirm the estimated arrival time, which in this case is the time shown in (2) of FIG. If the first operation of the switch S4 at this time is detected, it is detected in step S115 of FIG. 6, and in the next step S116, the value of the register L is set to 1 to set the point arrival estimated time display state, and in step S117. , A value (1 in this case) obtained by adding 1 to the value of the pass checkpoint number register R is set in the register SS. Then, in the subsequent display processing (FIG. 9), steps S160, S166, S167, S170, S1.
After 71, it is determined in step S180 that the value of the register L is 1, and the checkpoint designated by the value of the register SS (that is, 1), that is, the estimated arrival time of the first checkpoint (checkpoint data The estimated arrival time stored in the row address CP1 of the section CP is displayed on the digital display section 8i. In the next step S182, the drive mark display 8
f, the alive mark display body 8a, the trip mark display body 8c, and the point number display body 8h indicating the value (that is, 1) of the register SS are lit and displayed, and then step S1
74 to S176 and S165, the same processing as described above is executed. For example, as shown in (2) of FIG. 15, when the estimated arrival time at the first checkpoint is 22:30 on Wednesday, February 10th, the display on the display unit 8 is displayed at d in FIG. Like

When the switch S4 is further operated by the first operation of the switch S4 in the state of d in FIG. 14, the step S12 of FIG.
6, the value of the register SS is increased by 1 by 2 in the next step S127, and the value of the register SS does not exceed the value of the set checkpoint number register MP in step S128. Display all estimated time of arrival and judge that it is not over. Then, in the display processing (FIG. 9), steps S180 to S182 and S174 to S176 to S16 are performed as described above.
The process 5 is performed, and the estimated arrival time of the second checkpoint designated by the value of the register SS (that is, 2) is displayed on the display unit 8. For example, as shown in (2) of FIG. 15, when the estimated arrival time is 22:30 on Wednesday, February 10, the display on the display unit 8 is as shown in FIG.
It becomes like e of 4.

Thereafter, every time the switch S4 is operated, the same operation as described above is performed, the value of the register SS is increased by 1, and the estimated arrival time at the checkpoint designated by the value of the register SS is displayed on the display unit. It is displayed on 8. In this way, when the estimated arrival time relating to the final check point (goal point) is displayed (see f in FIG. 14) and the switch S4 is operated after confirming this, the time shown in FIG. In step S128, it is detected that the value of the register SS exceeds the value of the set checkpoint number register MP, the value of the register L is set to 0 in step S129, and the total distance is displayed on the display unit 8, that is, in FIG. Return to the state of b.

When the drive is continued as described above and the first checkpoint is reached, the switch S1 is operated. In this case, the operation is performed in step S1 of FIG.
In step S108, the value of the pass checkpoint number register R is incremented by 1 and set to 1, and in the next step S109, the pass checkpoint number register R is set.
The new value of is still set Checkpoint number register MP
It is determined that it is not equal to the value of, that is, the current checkpoint is not the final checkpoint (goal point), and the process proceeds to step S112. Then, in step S112, the difference between the current time from the time / date counting circuit 4 and the estimated arrival time of the first checkpoint is calculated, and based on this, the remaining checkpoints, that is, the second, third, ... The estimated arrival time is recalculated and the subsequent estimated arrival time stored in the checkpoint data section CP is corrected based on the result. That is, when this is explained with reference to (2) and (3) of FIG.
Although the arrival time at the checkpoint was 22:30 (see (2) in the figure), when it actually arrived at the first checkpoint with a delay of 5 minutes at 22:35 (see the figure). (3)), the difference between the above two times (that is, 5 minutes) is calculated, and the arrival time at each subsequent checkpoint stored in the checkpoint data section CP is uniformly delayed by the above difference, that is, 5 minutes. correct. In the above process, as shown in (4) of FIG. 15, when the arrival arrives earlier than the scheduled arrival time, each subsequent arrival time is corrected to be earlier than that. .

As described above, step S112 in FIG.
After the processing of step 1 is completed, the process proceeds to step S113, a clear signal is sent to the timer 7 to clear the counted elapsed time (time elapsed during traveling from the start point to the first check point) and The distance is set to 0, and in the next step S114, the position indicated by the hour hand 22 is set to the position at 1 o'clock to indicate that the first checkpoint has already passed, and the hour hand position instruction register N
The value of H is increased by 5, but in this case, the value of the hour hand position instruction register NH is 0 (see step S94 of FIG. 6), and thus becomes 5 by the process.

Next, in the display process (FIG. 9), step S
The total distance of the total distance register T is displayed on the digital display unit 8i in step S172 through 160, S166, S167, S170, and S171, and then in step S17.
In 3, the drive mark display body 8f, the trip mark display body 8c, and the value of the passing checkpoint number register R added with 1 (that is, 2 in this case) are lit and displayed, and the next step In S174, the speed related to the second checkpoint (that is, the speed set in the row address CP2 of the checkpoint data portion CP and the traveling speed from the first checkpoint to the second checkpoint) is displayed by the second hand 14. In order to do so, the second hand position instruction register NS is set. After that, the process proceeds to steps S175, S176, and S165, and the same processing as described above is executed.

After that, unless the switch is operated, the process returns to step S1 of FIG. 3, and proceeds to step S6 through steps S10 and S5 to determine whether or not there is a 1 Hz signal from the frequency dividing circuit 3. If not, The process directly proceeds to the display process of step S8, but when the signal is present, step S7
That is, the process proceeds to the distance calculation process of FIG. 7, and step S145
Through the processing of S148, the checkpoint data section C
The travel distance for one second is calculated from the speed related to the second check point of P, and the distances of the distance register CT and the total distance register T are made longer by the above travel distance,
After that, the process proceeds to step S8 of FIG. 3, that is, the display process of FIG. 9, and steps S160, S166, S167, and S17.
The operation of executing the processes of 0 to S176 and S165 is repeated. It should be noted that if the second checkpoint has not been reached even after the scheduled arrival time at the second checkpoint has been reached due to the repetition of such operations and the passage of time, the display processing (FIG. 9) described above is performed. In step S175, the distance of the distance register CT is the checkpoint data part CP.
It is determined that the distance is larger than the distance related to the second check point of step S175, and the process directly proceeds from step S175 to step S165. Since the processing of step S176 is not executed, the minute hand 18 is not moved.

Hereinafter, the switch S1 is operated each time the second, third, fourth, ... Check points are reached, and the same operation as described above is performed each time.

Next, for example, as shown in (5) of FIG. 15, while traveling between check points (that is, between Hashimoto and Atsugi), the traveling speed between the check points is changed (from 50 Km / h to 30 Km). / H) will be described. In this case, first, the switch S2 is operated as shown in FIG. At this time, the operation is detected in step S118 of FIG. 6, the value of the register L is set to 2 in step S119, the speed is changed, and the next step S120.
At a speed related to a checkpoint (third checkpoint in this case) having a value obtained by adding 1 to the value of the passing checkpoint number register R (that is, the traveling speed at that time is 5
0 km / h) is set in the speed register Z. And
In the subsequent display process (FIG. 9), the total distance of the total distance register T is displayed on the digital display portion 8i in step S185, and the drive mark display 8 is displayed in step S186.
f, speed mark display 8d, set mark display 8
The point number display 8h having a value obtained by adding 1 to the value of e and the passing check point number register R is lit and displayed, and in the next step S187, the current speed set in the speed register Z is displayed by the second hand 14. Therefore, the speed is set in the second hand position instruction register NS. After that, step S
175, S176, and S165 are executed, and the same processing as described above is executed. After the above state, the switch S1 is operated to increase the speed and the switch S4 is operated to decrease the speed. At this time, the operation of the switch S1 is performed in step S of FIG.
The operation of the switch 130 and the switch S4 is performed in step S132 of FIG.
The speed of the speed register Z is increased or decreased by 2 Km in steps S131 and S132, respectively. Then, the speed of the speed register Z thus changed is set in the second hand position instruction register NS in step S187 of the subsequent display processing (FIG. 9), and in step S165.
It is displayed by the second hand 14 in the pointer movement process (see c in FIG. 14).

After changing the speed to a desired value (30 km / h in this case) as described above, the switch S2 is operated again as shown in FIG. At this time, the operation is detected in step S134 of FIG.
In step S136, the value of the register L is returned to 0, and in step S136, the changed speed set in the register Z is set as the speed corresponding to the checkpoint of the value obtained by adding 1 to the value of the checkpoint number register R and the checkpoint Data part C
The data is stored in the corresponding row of P (in this case, 30 Km / h set in the speed register Z is set in the row of the row address CP3 of the checkpoint data section CP as the speed related to the third checkpoint). Then step S
At 137, the estimated arrival times of the remaining checkpoints are recalculated, and the respective estimated arrival times of the checkpoint data portion CP are corrected based on the result. That is, the travel distance from the immediately preceding checkpoint (in this case, Hashimoto) is calculated from the elapsed time from the timer 7 and the speed before the change, and this traveled distance is calculated as the immediately preceding checkpoint and the next checkpoint (in this case, Atsugi). Distance between (set in the checkpoint data section CP)
Further, the remaining distance to the next check point is calculated, and the remaining distance is divided by the speed after the change to calculate the time required to reach the next check point. Next, this required time is added to the current time from the time / date counting circuit 4 to obtain the estimated time of arrival at the next checkpoint, and this time and the checkpoint data section C are obtained.
The difference from the corresponding estimated arrival time set in P (in this case, the estimated arrival time to Atsugi before correction) is calculated, and by this difference, the difference between the next check point set in the check point data section CP and Correct the estimated time of arrival for each checkpoint.

As described above, step S137 in FIG.
After performing the estimated time recalculation storage process of
Each time the process proceeds to step S7 of FIG. 7, that is, the distance calculation process of FIG. 7, the traveled distance for one second is obtained based on the changed new speed,
The distances of the distance register CT and the total distance register T are made longer by the traveling distance. Then, in the display process (FIG. 9), steps S172 to S176,
The process of S165 is executed in the same manner as described above, but in step S174, the new speed is displayed by the second hand 14 in order to display the new speed by the second hand 14.
, And the pointer is displayed in step S165.

As described above, when the final check point (goal point) is reached, the switch S1 is operated in the same manner as when the other check points are reached. At this time, the operation is detected in step S107 of FIG. 6, and the passing checkpoint number register R is detected in the next step S108.
Is increased by 1, and in step S109, it is determined that the value of the passing checkpoint number register R becomes equal to the value of the set checkpoint number register MP and the final checkpoint is reached, and it is determined in step S11.
Go to 0. In this step S110, the value of the flag FS is set to 0, and then a reset signal is sent to the RS flip-flop 6 in step S111 to close the AND gate 5 and stop counting the elapsed time by the timer 7.

After the above switch processing, that is, the processing of step S4 in FIG. 3, is finished, the flag F is set in step S5.
It is determined that the value of S is not already 1, and the process proceeds to step S8, that is, the display process of FIG. 9, and step S172.
The processes of S176 to S165 are executed in the same manner as described above.

The above operation is performed when each checkpoint set in the checkpoint data portion CP in the plan mode is sequentially passed and the drive is performed up to the final checkpoint. When the drive is stopped before reaching the point, the operation of the switch S1 is continuously performed for 2 seconds or more. At this time, in response to the operation of the switch S1, as described above,
First, the processes of steps S1 to S8 of FIG. 3 are executed, and then the process returns to step S1 and steps S2, S15, S1.
A series of processes S6, S5 to S8, and S1 (that is, a process accompanying the operation of the switch S1 that is performed every time the checkpoint is passed) is repeated for up to 2 seconds. When 2 seconds have passed, step S
In step S17, the process proceeds to step S17. Then, in this step S17, it is determined that the value of the mode register M is 1 and the drive mode is set, and in the following step S18, the value of the register N is 1 or 2, and the measurement is performed with or without a plan. It is determined that the operation is in progress, and the process proceeds to step S19, that is, the reset process of FIG. Then, in step S150, it is stored that the value of the flag FS is set to 0 and the measurement of the elapsed time by the timer 7 is stopped,
Then, in step S151, the RS flip-flop 6
Then, the AND gate 5 is closed by sending a reset signal to and the measurement of the elapsed time by the timer 7 is actually stopped. Next, in step S152, the total distance in the total distance register T is deleted, and in step S153, the distance register C is deleted.
The distance T, that is, the distance from the immediately preceding checkpoint is erased, and in step S154, the value of the register N is set to 0, and a reset state in which measurement is not performed is performed.

After the reset process in step S19 of FIG. 3 is completed as described above, the process proceeds to step S8, that is, the display process of FIG. 9 through step S5, and step S1.
60, S166 to S169, and S163 to S165 are performed, and a display as shown in FIG.

The above operation is performed when the plan is set in the checkpoint data section CP in the plan mode and then the drive mode is set and the drive is performed in accordance with the plan, that is, the plan exists (the value of the register N is 1). The above-mentioned plan is not set in the checkpoint data portion CP, but the operation state in the plan non-state (the value of the register N is 2) will be described. To carry out the measurement without this plan, refer to FIG.
As shown in (1), the value of the register N is reset to 0 and the switch S1 is operated at the start of driving. In this case, the operation is detected in step S86 of FIG. 6, and in the next step S87, the value of the setting data flag CL is 0 instead of 1, and it is determined that the plan is not set in the checkpoint data portion CP. Judge and step S
Go to 100. Then, in this step S100, the value of the register N is set to 2, the value of the flag FS is set to 1 in the next step S101, and the fact that the measurement has started is stored, and then the value of the register J is set to 0 in step S102. The state in which the total distance of the total distance register T is displayed on the digital display unit 8i is designated.

After the above switch process, that is, the process of step S4 of FIG. 3, is completed, steps S5 and S6 of FIG.
After that, the process proceeds to step S8, that is, the display process of FIG.
And steps S160, S166, S167, S17
After 0, it is detected in step S190 that the value of the register J is 0, and in the next step S191, the drive mark display body 8f and the trip mark display body 8c are turned on. Next, in step S192, the total distance of the total distance register T (in this case, it is 0 immediately after start) is displayed on the digital display unit 8i, and in step S193, the speed set in the speed register Z is displayed.
In order to display with the second hand 14, the speed is set in the second hand position instruction register NS, and after that, steps S163 to S16.
Proceeding to the process of 5, hand movement such as displaying the speed set in the speed register Z with the second hand 14 is performed.

After the above processing, as long as the operation of the switch S1 is continued, the switches S1, S2, S1
5, S16, S5, S6, S8 are repeated, and after the above operation is stopped, steps S1, S10, S1 are performed.
1 and S5, and from the frequency divider circuit 3 to 1 Hz in step S6.
When there is a signal, the process proceeds to step S7, that is, the distance calculation process of FIG. Then, in step S145, it is determined that the value of the register N is not 1 but 2 and the process proceeds to step S149 to find the distance to advance in one second from the speed of the speed register Z, and then in step S148, the total distance. The total distance of the register T (in this case, it is 0 immediately after the start) is made longer by the distance for advancing in the above 1 second.

After the distance calculation process of step S7 of FIG. 3 is completed as described above, step S8, that is, FIG.
The display processing of step S191 to S
The processing of 193 and S163 to S165 is executed.

Hereinafter, the above operation is repeated,
The total distance of the total distance register T is set, and it is displayed on the digital display portion 8i. The drive is performed in this way, and when the drive is interrupted, the switch S1 is operated. In this case, it is determined in step S1 in FIG. 3 that the switch has been operated.
In step S25, S3, the process proceeds to step S4, that is, the switch process of FIG.
5, the process proceeds to step S37, that is, the drive mode switch process of FIG. And steps S85 and S10
5, the process proceeds to step S138, that is, the plan non-switching process of FIG. 11, and it is determined in step S230 that the value of the register J is 0, and the next step S23.
When it is detected that the switch S1 is operated in 1, it is determined in step S232 that the value of the flag FS is 1 instead of 0, and then in step S234, the flag F is determined.
The value of S is 0. In this way, the value of the flag FS is set to 0.
After that, steps S5 to S6 of FIG.
Since the total distance of the total distance register T is not updated in the distance calculation processing (FIG. 7) in S7, the display processing of the step S8 directly proceeds from the above step S5. The total distance when the switch operation for interruption is performed is continuously displayed.

When the drive is restarted after the above interruption, the switch S1 is operated again. in this case,
The operation is detected in step S231 of FIG. 11, and the value of the flag FS is returned to 1 in step S233 through step S232. After that, since the value of the flag FS is 1, the process proceeds from step S3 to step S6 of FIG. 3 to step S7, that is, FIG. 7 every 1 second, and the total distance of the total distance register T is updated. , Steps S191 to S193, S1 of the subsequent display processing (FIG. 9)
The processes of 63 to S165 are executed and the total distance is displayed on the digital display portion 8i.

Further, when the speed of the speed register Z is to be changed during the driving without the plan,
As shown in FIG. 14, first, the switch S2 is operated. In this case, the operation is detected in step S235 of FIG. 11, and the value of the register J is set to 1 in the next step S236 so that the speed can be changed. Then, the switch S1 or S4 is operated to actually change the speed of the speed register Z, but the speed register Z is operated when the switch S1 is operated.
Is set to be 2 Km / h faster (step S24
0, S241), and when the switch S4 is operated, the speed of the speed register Z is slowed by 2 Km / h (steps S242, S243). In this case, subsequent to each of the switch processes described above, the steps S194, S192, S193, S163 to S163 to S163 of the display process (FIG. 9) are performed each time.
The processing of step 165 is executed, and the changed speed of the speed register Z is displayed by the second hand 14 (for example, when the total distance of the total distance register T is 12.07 Km, the speed is changed to 60 Km / h). When I did
The display on the display unit 8 or the like is as shown in FIG.

As described above, the switch S1 or S4
After changing the speed of the speed register Z by operating
As shown in FIG. 4, by operating the switch S2, the register J
The value is set to 0 to return to the total distance display state. In this case, the operation is detected in step S244 of FIG. 11, and the value of the register J is returned to 0 in step S245. Then, in the subsequent display processing (FIG. 9), steps S191 to S193,
The processes of S163 to S165 are executed, and the changed speed is displayed by the second hand 14. Then, in the subsequent distance calculation processing (step S7 of FIG. 3, that is, FIG. 7), the total distance of the total distance register T is updated based on the changed speed (step S149,
S148).

As described above, the drive is performed without this plan, and when the drive is finished (that is, when the call point is reached), the switch S1 is operated in the same manner as when the drive is interrupted. However, as a result, the same operation as when the drive is suspended is performed (steps S230 to S232, S234,
Steps S190 to S193 and S163 to S16 of FIG.
5). At this time, when the operation of the switch S1 is continued for 2 seconds or more, the same operation as that in the plan state is performed, that is, the step S19 of FIG. 3, that is, the reset process of FIG. The state 14a, that is, the reset state.
