System for warning against forgetting to pull out information recording medium
First Claim
1. A system for warning against forgetting to pull out an information recording medium, said system comprising:
- a battery that is installed on a vehicle;
a navigation unit that is installed on said vehicle;
an on-board radio unit that is installed on said vehicle with an information recording medium being attached to the on-board radio unit and removed the on-board radio unit;
a drive unit switch that is connected to the battery for controlling to drive and stop a drive unit that is mounted on said vehicle for driving thereof;
a control part that is connected to said drive unit switch through a power supply line, and to said on-board radio unit through a communication line and an on-board radio unit power supply line; and
a notification part that is mounted on said navigation unit for notifying a residual state of said information recording medium to a user;
wherein said control part detects when said drive unit switch has been turned off, also detects the residual state of said information recording medium with respect to said on-board radio unit through said communication line thereby to notify it to said notification part, and interrupts the supply of power to said on-board radio unit through said on-board radio unit power supply line when said information recording medium is absent.

Abstract
A system for warning against forgetting to pull out an information recording medium can improve working efficiency upon mounting a navigation unit and an on-board radio unit onto a vehicle, and notify a user of an alarm that causes no uncomfortable feeling, and is still inexpensive to manufacture. A drive unit switch detects when a control part is turned off, also detects, through a communication line, a residual state of an IC card with respect to an on-board device, and notifies the result of the detection to a the voice generation part. When the IC card is “absent” in the on-board device, the control part interrupts the supply of power to the on-board device through the on-board device power supply line.
