【Example】

Example 1. FIG. 1 is a block diagram of a recording / reproducing apparatus for mobile navigation according to an embodiment of the first or second invention. In the figure, 1 to 16a are the same as those of the conventional system shown in FIG. 14, and their respective functions and operations are almost as described above, and detailed description thereof will be omitted.

Here, the conventional device is the CD-ROM 16a.
It is intended to provide a more convenient and easy-to-use device by adding a device capable of arbitrarily recording and reproducing various navigation information and other information, while being constructed on the basis of a reproduction-only memory.

Various information recording media are conceivable, but those having a large recording capacity and a high access speed are desired in order to support the navigation function.
In the present invention, a mini disk (Mini Disc, hereinafter, referred to as MD) that fits exactly this requirement is used as a recording medium.

MD is, for example, Nikkei Electronics 1
As disclosed in the article "Mini disk, realization by magneto-optical recording and data compression technology" on December 5, 991, P.160 to P.168, the diameter was only 64 mm and it was stored in a cartridge. The optical disc is easy to handle. Despite its small diameter, its recording capacity is 120 Mbytes or more, and it is a medium that can record a large amount of image data, audio data, and other data so that there is no practical problem.
There are two types of MDs, which are read-only like the conventional CD-ROM 16a, and an erasable type in which recording and reproduction can be performed many times by a magneto-optical recording method. In the present invention, the latter erasable MD is used. .

In FIG. 1, 17 is an MD deck for recording / reproducing an MD, and 17a is an erasable MD which is a recording medium. Here, a read-only CD-ROM 1
Since 6a can be recorded / reproduced, that is, rewritten, it is referred to as MD-RAM for convenience.
This erasable MD 17a will be referred to as MD-RAM 17a. Reference numeral 18 denotes a fourth interface circuit, and the operation of the MD deck 17 is controlled by the CPU 5 via the fourth interface circuit 18.

As one of the applications of a system to which a recording / reproducing device such as the MD deck 17 is added,
It is possible to realize an operation recording system that automatically records the route and time spent by a car to reach its destination. When the driver starts driving the vehicle, the driver specifies the navigation mode by the key switch group 9, and further specifies the operation recording mode by the key switch (not shown) newly added to the key switch group 9. As described above, when the navigation mode is selected, the CD-RO
The map information having the position (X0, Y0) of the starting point is read from M16a and displayed on the CRT 10. When the car starts traveling, the distance sensor 13, the direction sensor 12,
The GPS device 11 is activated to generate traveling route information such as traveling distance and traveling locus, and the traveling locus of the automobile as shown in FIG. 17 is displayed on the screen of the CRT 10 accordingly. When the traveling position of the automobile exceeds the predetermined area of the map currently being displayed, the adjacent map information is read from the CD-ROM 16a, the screen is automatically switched, and the traveling locus of the automobile is displayed without interruption. It
By visually recognizing this, the driver can easily reach the destination. While operating such a navigation function, the CPU 5 controls the MD deck 17 to sequentially record various information in the MD-RAM 17a.

The information recorded in the MD-RAM 17a includes map information output from the CD-ROM 16a and displayed on the CRT 10, travel distances calculated by the CPU 5, travel route information such as travel loci, and other time information. , Calendar information such as date, and the like, which are respectively recorded in the MD-RAM 17a in a predetermined format.
Since the recording format of the MD is almost the same as that of the CD-ROM 16a, the format of the recorded map information is almost the same as that of the CD-ROM 16a. (However, it is not always necessary that they are the same.) Regarding the travel route information, conventionally, RA for temporary storage is used.
Although it was stored in the M6, it is a format that adds time information, calendar information, etc., and also corresponds to one map information, and is a format in which a plurality of information is collected.
-Record in the RAM 17a. At this time, in order to indicate which map information corresponds to, the map number, name, or address information indicating where on the CD-ROM 16a the map information is recorded is also recorded. Since the RAM 6 for temporary storage stores a plurality of travel route information, its storage capacity is larger than that of the conventional system.

FIG. 2 shows an example of a format in which the above-mentioned information is recorded in the MD-RAM 17a. 2A shows an example of a recording format of map information, and FIG. 2B shows an example of a recording format of travel route information. In both (a) and (b), MD-
There is an area 51 on the RAM 17a where address information is recorded, and then there is an area 52 where a code for identifying the recorded content is recorded. A code indicating map information is recorded for (a), and a code indicating traveling route information is recorded for (b). Reference numeral 53 is an area in which the address information of the CD-ROM 16a corresponding to the map information recorded in the MD-RAM 17a is recorded, and 54 is an area in which the number, name, etc. of the map information are recorded. Reference numeral 55 is an area in which data is recorded, and the content of data differs depending on the recorded content identification code recorded in 52. In the case of (a), the map information is recorded in the case of (b), and a plurality of calendar information 56, time information 57, and travel route information 58 are recorded together.

The data of the format example as described above is
FIG. 3 shows how the data is sequentially recorded on the MD-RAM 17a as the vehicle runs. The MD-RAM 17a has an area for recording main data and a TOC recording area for recording a table of contents of the main data. When the operation record mode is started, the first map information read from the CD-ROM 16a is recorded in the MD-RAM 17a in the format example shown in FIG. 2 (a), and then the map is traveled within the range. The route information is recorded. CD-ROM 16
When the next map information is read from a, it is MD-R.
It is recorded in the AM 17a, and subsequently, the traveling route information related thereto is recorded. In this way, the map information and the travel route information are sequentially recorded in pairs until the operation recording mode is released. In the example of the operation record 1 of FIG. 3, eight pieces of map information are CD-ROM 16a from the start of running.
It is shown that it is read out from the computer and recorded on the MD-RAM 17a together with the traveling route information.
In the example, 10 pieces of map information and travel route information are sequentially recorded. In addition, when there are a large number of driving route information for one piece of map information, as shown in the location of the operation record 1 in FIG. 3, the driving route information (8) -1, for the map information (8),
(8) -2 and so on.

Until the operation record is started and released,
As described above, the map information and the traveling route information are sequentially recorded in the main data recording area of the MD-RAM 17a, but when the operation recording mode is released, the TOC (T
The table of contents information regarding the operation record contents up to that point is recorded in the "able Of Contents" recording area. That is, as shown in FIG. 3, in the TOC area, the program number and the MD-RAM at the head position of the operation record up to that point are stored.
Address information, program name, calendar information,
Other information is recorded. The name of the program can be entered by operating the keys of the key switch group 9 and can be set freely. The key operation can be omitted when setting is not required. In this way, if the table of contents information is recorded in the TOC area, MD
-When the RAM is reproduced, by reading the TOC area table of contents information first, the start position of the main data area in which the desired operation record is recorded can be instantly accessed. Other information included in this table of contents information includes the number of pieces of recorded map information or the address information of the MD-RAM at the recording position of each piece of map information.
These allow access not only from the beginning of one operation record, but from the middle.

In the example of FIG. 3, the data of the operation record 2 is recorded continuously to the operation record 1, but since the table of contents information of each operation record is recorded in the TOC area, the main data area is recorded. , It is not necessary to record continuously,
It may be recorded in a vacant area in a scattered manner.

A case where the operation record recorded in the MD-RAM 17a is reproduced later will be described. When the operation record / playback mode is designated by a key switch (not shown) newly added to the key switch group 9, the CPU 5 causes the fourth
The MD deck 17 is controlled through the interface circuit 18 to start the reproduction of the MD-RAM 17a.

The MD deck 17 is initially the MD-RAM 1
The table of contents information recorded in the TOC area of 7a is read and transmitted to the CPU 5. The CPU 5 uses the received table of contents information as C
RT. Display on CRT 10 via C7. The user can freely select a desired operation record by key operation from the program number, name, calendar information, etc. of the displayed table of contents information. When the operation record to be reproduced is determined, the data area in which the operation record is recorded is accessed at high speed, and the MD deck 17 sends the map information of the specified operation record and the traveling route information of the pair to the CPU 5. Send. The CPU 5 sends the received map information and travel route information to the CRT. It is synthesized and displayed on the CRT 10 via C7 for output display. When you want to see the next screen, you can specify the next screen by key operation. When the next screen is designated, the next map information and the traveling route information of the pair are instantly displayed. Thereafter, similarly, the map information and route of the designated operation record are displayed. When the display of all the map screens is completed, the screen of the table of contents information is displayed again, and the desired operation record can be selected again. When the operation recording / playback mode is released, the CPU 5 stops the playback operation of the MD deck 17.

Example 2. This is related to the case where the operation record recorded in the MD-RAM 17a is reproduced to perform navigation, and this is a convenient function when reaching the destination and returning to the starting point through the same route again. is there. When the driver starts driving the vehicle, the driver specifies the navigation mode and the operation recording / reproducing mode by using the key switch group 9. The CPU 5 controls the MD deck 17 via the fourth interface circuit 18, and MD-
The reproduction of the RAM 17a is started.

The MD deck 17 reads the table-of-contents information recorded in the TOC area of the MD-RAM 17a,
Send to U5, which is then displayed on the CRT 10. The driver specifies the operation record to the destination by key operation. When the operation record to be reproduced is determined, the MD deck 17 will now determine the number of pieces of map information recorded in the TOC area table of contents information and the M of the last map information recording position.
The address information of the D-RAM is read, the data area in which the last map information of the designated operation record is recorded is accessed at high speed, and the last map information and the traveling route information of the pair are transmitted to the CPU 5. Explaining based on FIG. 3, for example, if the operation record 1 is specified, the last map information
(8) and the traveling route information (8) -1, (8) -2 will be read. The CPU 5 sends the received map information and travel route information to the CRT. It is synthesized and displayed on the CRT 10 via C7 for output display.

When the automobile starts running, the distance sensor 1
3, the azimuth sensor 12 and the GPS device 11 are operated to generate traveling route information such as traveling distance and traveling locus, and the traveling locus shown by dots in FIG.
It is displayed on the screen of T10. Since the original route (thick line in Fig. 17 (b)) has been returned, the current running locus (dotted line) and the previous running locus naturally overlap.
When the traveling position of the automobile exceeds the predetermined area of the map currently displayed, the previous map information and traveling route information are read from the MD-RAM 17a, the screen is automatically switched, and the current traveling locus is displayed. And the previous running trajectory is displayed without interruption. Since the driver can travel while visually checking the previous travel path, the driver can return to the original starting point more easily than the navigation using only the CD-ROM.
