It generates a signal and outputs it to the Napid data device 11 and the speedometer (not shown) of the car. In other words, when the P computer 12 is attached to the computer mounting part 13, the connector bin 23 is inserted into the connector part 22, and the internal circuit of the P computer 12 is connected to the internal circuit of the navigator device 11. Further, the above-mentioned recording device 11 and the microphone 16 are connected by a connection cord 24. Furthermore, the microphone 16 is provided with a microphone switch 16B.

Next, the configuration of the internal circuits of the navigator device 1 and the P computer 12 will be explained with reference to FIG. The navigator device 1 is provided with a control device 31 . This control device R31 controls the tape mechanism section 15 in response to instructions from the P computer 12! Gives control commands such as PLAY, recording (RFC), fast forward (FF), rewind (REW), and f (STOP). The tape mechanism section 15 drives the cassette chip fz4 to travel according to commands from the control device 3. Further, the control device 3 is connected to the tape mechanism section 15 via the interface 32,
Specific information is read/written to the cassette tape 14. The interface 32 converts the start code, end code, distance data, etc. using KO2 (Kansas City Standard) or the like.

Further, a speaker 33 and the microphone 16 are connected to the tape mechanism section 15 .

Further, a counter 34 is connected to the control device 31 and is configured to count the noculus from the converter 20 and output the counted value to the control device 31. The counter 34 is reset by a command from the control device 31. By installing the P computer 2 in the apparatus main body 11 configured as described above, the control device 3 in the apparatus main body 1 is connected to the CPU 41 in the P computer 12.

In the P computer 12, the M memory 43
, an arithmetic unit 44 , and a memory 45 for storing arithmetic data are connected thereto, and a display section 47 is also connected via a display drive device 46 .

The P computer 12 configured as described above has general functions as a computer.

Next, the operation of the above embodiment will be explained. First, the P computer 12 is attached to the navigator device 11. Next, the program chip 7' 14a is attached to the tape mechanism section 15, and
By operating the rLOAD and J keys provided on the P computer 12, the program stored in the program chip f14a is read out to the CPU 41 of the P computer 12 via the interface 32 and the control device 3, and the program is read out to the CPU 41 of the P computer 12. 43. The program code 7' 14m includes a program code 1.1 in the program language of the P computer 12, for example, RASIC. Two programs are stored in advance. The above program 1
is for performing control according to the flow in the recording mode shown in Fig. 4.
This is to perform control according to the flow in the playback mode shown in the figure. The above Grogramti 1. P 2
After being loaded into the computer 12, by executing the program, predetermined keys of the keyboard 42 operate as a recording mode designation key, a playback mode designation key, a start key, and an end key. When a mode is designated by operating the recording mode designation key and the playback mode designation key, the designated mode is determined by the CPU 4j, and a program is executed according to the mode. That is, CPU4
Step 1 determines whether the mode is recording mode or playback mode as shown in step fs in FIG. Execute the processing of grammatical program 2 shown in step B.

After the above program loading is completed, the guidance tape 14b is attached to the tape mechanism 15 instead of the glogram cheese 7' 14a, and the car is actually driven to record the guidance information on the road 1B'. To record this route guidance information, first operate the recording mode key to specify the recording mode.When you specify this recording mode,
As described above, the process proceeds from the mode determination step S in FIG. 3 to step 7''A, where the processing of the program check 1 is executed.

The recording operation of route guidance information performed according to this program ÷1 will be explained in detail below with reference to the flowchart of FIG. When the recording mode is designated, the CPU 41 sends a control command to the control device 3) to run the tape in the recording state as shown in step A in FIG. Then, at step fA, a guidance star)+j-1'sTc is written on the guidance tape 14IL as shown in FIG. When the writing of the start code STC is completed, the tape is stopped running as shown in step A, and the process goes to step A4, where it is in a HALT state until the microphone switch 16s is turned on. When the microphone switch 16B is turned on in this state, the tape starts as shown in step fk, and then the microphone switch 16B is turned on.
Since the tape running state is maintained as shown in Stella fA6 until the FJ is turned off, the intro guidance is recorded during this time. For example, [This tape will guide you through the course starting from Company A and ending at Company B. Record the introductory guidance "Press the start key when you turn toward Shinjuku at the intersection of 2000." Entering the industrial park on Ome Kaido.

Since drivers often know the area around the starting point, they record the above-mentioned introductory guidance in order to decide on a landmark starting point and start guiding from there. After recording the intro guidance on the tape, turn off the microphone switch 16B, proceed to step A, write the strag code as shown in FIG. 6 after the intro guidance, and stop the tape in step A. do. When the tape stops running, the process advances to step 80 and remains in a halt state until the start key is operated.

After recording the intro Ignus as described above, drive the car to the location indicated in the intro guidance, and at that point, in other words, in this example, "the place where you turned towards Shinjuku at the industrial park entrance intersection". Operate the start key. Step A key When the start key is operated while waiting for human power, step A. Then, the CPU 41 sends a reset signal to the counter 34 via the control device 31 to reset 70 Uchitani. This counter 34 counts the pulses given from the converter 20 every time the car travels a certain distance. Therefore, the count value of this counter 34 corresponds to the distance traveled by the car. When the counter 34 is reset in the above-mentioned Stetsuno Ale, Stella! The process advances to All, and enters a state in which it waits for the microphone switch 16B to be operated and for a signal to be input to the end key.

Then, when the user turns on the microphone switch 16B at an arbitrary point as the car travels and speaks at a landmark, the words are recorded. That is, STETSU fA,.

In the halt state, when the microphone switch 16B is turned on, the process proceeds to Stella f A , and the count value of the counter 34 is sent from the control device 3 to the memory 45 via the CPU 41 and written to the address specified by the CPU 41. It will be done. Next, the tape is started in step AI3, and the recordable state is maintained as shown in step AI4 until the microphone switch 16F3 is turned off.

Therefore, in this state, if you refer to the landmarks visible from the car and say something like, ``When you see the gas tank on your right, turn right at the next traffic light,'' the guidance will be as shown in Figure 6. This will be recorded on tape as "Guidance 1". In this case, not only guidance but also BGM etc. can be recorded. After recording the guidance, the microphone switch 16B is turned off. When the microphone switch 16B is turned off, the Stellar fA14 to Stellar fA
Proceed to ls and write a stop code after the above "guidance 1". Then, after stopping the tape at Stella f A , 8, it returns to Stetsuno All. Similarly, by turning on the microphone switch 16B at an arbitrary point and speaking at the mark, it is possible to record "Gay Dance 2", "Guidance 3", etc. on the tape.

In addition, when performing guidance recording as described above, each time the microphone switch 16s is turned on, the count value of the counter 34 at that time is changed to the memory 4 by the processing of step fA4.
1 is sequentially added to 5.

Then, when you arrive at your destination, press the end key. By operating this end key, you can move from STETSUNO ALL to STETSU7.
6A I? Proceed to and write the distance start code DST on the tape.
Write. Next, the process proceeds to step A18, where the distance data stored in the memory 45, that is, the distance data from the starting point to each guide recording point, is sent to the CPU 47.
As shown in FIG. 6, the distance data k ('l) is written on the tape as shown in Stella'fA+e, and then the end code END is written on the tape to end the guidance recording.

Next, although I recorded as above, Ida and ST fx4b
The operation of reproducing the guidance contents according to the driving of the car using the system will be explained with reference to the flowchart shown in FIG. Operate the playback key when starting Company A. By operating this playback key, the programmer 2 shown at Stella fB in FIG. 3 starts, that is, the playback flow shown in detail in FIG. 5, and first the tape is started at Stella fB. Next, at step fB, the tape recorded contents are read by the control unit 31, and the distance start code DS is read.
Distance data from T to end code END is sent to CPU4
1 to the memory 45. Then step B,
Go to , rewind the tape and set it to the start code STC position. From this state, the tape is started and the intro guidance is played back as shown by Stella fB, and at the same time, the presence or absence of a stop code is determined by Stella fBll. When a stop code is detected in this Stella fB, the process proceeds to step B, where the tape is stopped, and then the Stella fB is pressed until the start key is operated.
, becomes a halt state. The driver drives the car toward the start point specified by the introductory guidance, and operates the start key when the driver reaches the specified point.

When this start key is operated, the process advances to step B, where the counter 34 is reset, and at the Stella fB, the content of the counter 34 is subtracted from the distance data held in the memory 45, and the result of the subtraction is displayed on the display section 47. Display -). At this point, the distance data stored in the first address, for example "7", is read out from the memory 45, the content "0" of the counter 34 is subtracted, and the subtraction result "7" is displayed on the display section 47. The data displayed on the display section 47 indicates the distance to the next checkpoint.

Next is Stella f B.

The count contents of the counter 34 and the memory 45 are
Compare the distance data read from the .

As described above, the counter 34 counts up according to the distance signal sent from the converter 20 each time the car advances a certain distance, and each time the counter 34 counts up the step B. A comparison operation is performed.

Stella fB, above. If the comparison results do not match, the process returns to step B. The process of step B-+BIQ is repeated until the car advances to the next checkpoint. Then, as the car travels, the contents of the counter 34 count up, and the count value and the value read from the memory 45 "
7", the program advances to Stella f B , , and starts the tape to reproduce the contents of "Guidance I".

Next, the process advances to Stella 7'B□, and the presence or absence of a stop code and an end code is determined. If no code is detected, the tape is run as it is in the reproducing state. And this step BI! When a stop code is detected in step BI3, the tape is stopped and,
In step BI4, set the memory address to r+IJL,
Specify the next address in memory 45. Thereafter, return to step fB and perform step B described above.

B. Repeat the process. Then, the count value of the counter 34 and the distance data read out from the memory 45, for example, "15
When the car reaches a point where the numbers ``1'' and ``guidance 2'' match, tape 0 is started in step Bll and the inner world of ``guidance 2'' is played back. Thereafter, similar operations are performed to reproduce the guidance content as the p car advances. Then, driver e drives the car according to the voice guidance provided by playing the tape. Then, when the car approaches the destination and plays the final guidance, the code is subsequently read out to the encoder. When the end code is read out, the process proceeds from Stella f B , . . . to step BI5, the tape is stopped, and the guidance ends.

Note that the route guidance operation is not particularly limited to the above embodiment.
