Abstract

A movable information processing device which is provided with check means that checks whether or not both of moving distance information of the information processing device, which are stored in storage means for check and in a recording medium which can be dismounted from the information device when the storage medium is dismounted, agree with each other, and that allows supply of information such as navigation information only when these moving distance information agree with each other. The check means additionally checks at least one of difference between position information P1 stored in the storage medium when the storage medium is dismounted and present position information P2, and difference between day/time information T1 stored in the storage medium when the storage medium is dismounted and present day/time information T2, and allow supply of navigation information only when the checked results satisfy predetermined conditions.

Claims

1. A movable information processing device comprising:

a storage medium that is capable of storing information and being dismounted from the movable information processing device;

information supply means that supplies information on a basis of information read from the storage medium;

mount/dismount detection means that detects a state where the storage medium is dismounted and a state where the storage medium is again mounted;

moving distance detection means that detects an accumulated moving distance of the movable information processing device;

output means that outputs moving distance information acquired from the moving distance detection means to store in the storage medium and storage means for check when a state where the storage medium is dismounted, is detected by the mount/dismount detection means; and

check means that checks whether or not the moving distance information stored in the storage medium agrees with the moving distance information stored in the storage means for check when the state where the storage medium is again mounted, is detected by the mount/dismount detection means and that allows the information supply means to supply updated information only in a case both of the moving distance information agree with each other.

2. The movable information processing device as claimed in claim 1, further comprising position detection means that detects present position of the movable information processing device, wherein

the output means further outputs position information P1 acquired from the position detection means to store in the storage medium when the state where the storage medium is dismounted, is detected by the mount/dismount detection means, and

the check means allows the information supply means to supply updated information further in a case where difference between the position information P1 stored in the storage medium and present position P2 is within a predetermined range when the state where the storage medium is again mounted is detected by the mount/dismount detection means.

3. The movable information processing device as claimed in claim 1, further comprising day/time detection means that detects present day and time, wherein

the output means further outputs day/time information T1 acquired from the day/time detection means to store in the storage medium when the state where the storage medium is dismounted, is detected by the mount/dismount detection means, and

the check means allows the information supply means to supply updated information further in a case where difference between the day/time information T1 stored in the storage medium and present day/time information T2 satisfies a predetermined condition when the state where the storage medium is again mounted, is detected by the mount/dismount detection means.

4. A movable information processing device comprising:

a storage medium that is capable of storing information and being dismounted from the information processing device;

information supply means that supplies information on a basis of information read from the storage medium;

mount/dismount detection means that detects a state where the storage medium is dismounted and a state where the storage medium is again mounted;

moving distance detection means that detects an accumulated moving distance of the information processing device;

position detection means that detects present position of the information processing device;

day/time detection means that detects present day and time;

output means that outputs moving distance information D1 acquired from the moving distance detection means to store in the storage medium and storage means for check, and outputs position information P1 acquired from the position detection means and day/time information T1 acquired from the day/time detection means to store in the storage means, when a state where the storage medium is dismounted, is detected by the mount/dismount detection means; and

check means that checks whether or not the moving distance information D1 stored in the storage medium agrees with the moving distance information stored in the storage means for check and whether or not difference between the position information P1 stored in the storage means and present position information P2 is within a predetermined range and whether or not difference between the day/time information T1 stored in the storage means and present day/time T2 is within another predetermined range when the state where the storage medium is again mounted, is detected by the mount/dismount detection means, and that allows the information supply means to supply updated information only in a case where all the checked results satisfy predetermined conditions respectively.

5. The movable information processing device as claimed in claim 4, further comprising communication means that communicates with an external point, wherein the communication means delivers a notification to this effect to a predetermined communication destination in a case where checked results do not satisfy the predetermined conditions.

6. The movable information processing device as claimed in claim 4, wherein the storage medium that is capable of being dismounted is a hard disk drive and information stored in the storage medium is map information.

7. An information processing method comprising the steps of:

detecting an accumulated moving distance of a movable information processing device till a storage medium is dismounted from the information processing device;

outputting moving distance information detected by the step of detecting an accumulated moving distance to store in the storage medium and storage means for check; and

checking whether or not the moving distance information stored in the storage medium agrees with the moving distance information stored in the storage means for check when the storage medium is again mounted, and allowing information supply means to supply updated information only in a case where both of the moving distance information agree with each other.

8. The information processing method as claimed in claim 7, further comprising the steps of:

detecting a position of the movable information processing device when the storage medium is dismounted from the information processing device; and

detecting a day/time when the storage medium is dismounted, wherein

the outputting step further includes steps of outputting the position information detected by the step of detecting a position and the day/time information detected by the step of detecting a day/time to store these information in the storage medium, and

the checking step further includes steps of checking whether or not difference between the position information stored in the storage means and present position information is within a predetermined range and whether or not difference between the day/time information stored in the storage means and present day/time is within another predetermined range, and allowing the information supply means to supply updated information only in a case where these two information satisfy predetermined conditions respectively.

9. A storage medium that is capable of being dismounted from a movable information processing device and that stores as data for check an accumulated moving distance information of the information processing device when the storage medium is dismounted.

10. The storage medium as claimed in claim 9, wherein at least one of position information and day/time information when the storage medium is dismounted, are further stored as data for check.
