Patent Images
1. An onboard apparatus for reading information stored on a memory medium that is inserted into the apparatus from an opening for medium insertion, the apparatus for use in a vehicle comprising:
- a position detector for acquiring a current position of the vehicle;
a map reader for reading map data;
an area locator for determining whether the vehicle is in a dusty area based on the current position of the vehicle derived from the position detector and the map data derived from the map reader; and
a dust protector for protecting the apparatus from intrusion of dust through the opening in a preventive manner,wherein the dust protector performs a preventive operation for protecting the apparatus from intrusion of dust when the current position of the vehicle is located in the dusty area.

Abstract
An on-board unit includes a dust sensor for detecting an amount of dust in an air in a vehicle. When the amount of dust is equal to or greater than a predetermined value and a front panel of the unit is open, the front panel is moved to close a media slot and insertion/ejection operation of a medium is prohibited as a preventive measure for dust intrusion.

4. An onboard apparatus for reading information stored on a memory medium that is inserted into the apparatus from an opening for medium insertion, the apparatus for use in a vehicle comprising:
-
a position detector for acquiring a current position of the vehicle; a dust sensor for detecting an amount of dust in an air in the vehicle; and a position recorder for recording a dusty position that identifies a position where the dust in an amount that is equal to or greater than a predetermined value is detected by the dust sensor; a position locator for determining whether the vehicle is going to pass the dusty position based on the current position derived from the position detector and information derived from the position recorder; and a dust protector for protecting the apparatus from intrusion of dust through the opening in a preventive manner, wherein the dust protector performs a preventive operation for protecting the apparatus from intrusion of dust when the position locator determines that the vehicle is going to pass the dusty position recorded by the position recorder. - View Dependent Claims (5, 6)
