Abstract

An electronic apparatus to which a portable apparatus is attachable, the electronic apparatus including: a second connecting line connected to a first connecting line provided in the portable apparatus; a detector detecting an attachment of the portable apparatus, when the second connecting line is electrically connected to the first connecting line, and detecting a detachment of the portable apparatus, when the second connecting line is electrically disconnected from the first connecting line; and a resent transmitter transmitting a rest signal to the portable apparatus through the second connecting line and the first connecting line.

Claims

1. An electronic apparatus to which a portable apparatus is attachable, the electronic apparatus comprising:

a second connecting line connected to a first connecting line provided in the portable apparatus;

a detector detecting an attachment of the portable apparatus by use of the first connecting line and the second connecting line, when the second connecting line is electrically connected to the first connecting line, and detecting a detachment of the portable apparatus by use of the first connecting line and the second connecting line, when the second connecting line is electrically disconnected from the first connecting line; and

a reset transmitter transmitting a reset signal to the portable apparatus through the second connecting line and the first connecting line, the reset signal initializing an operation of a microcomputer of the portable apparatus.

2. The electronic apparatus as claimed in claim 1, wherein a ground voltage is applied to the second connecting line when in connection with the first connecting line, and is opened when in disconnection from the first connecting line.

3. The electronic apparatus as claimed in claim 2, wherein a voltage of a power supply is applied to the second connecting line when the reset signal is transmitted.

4. The electronic apparatus as claimed in claim 1, wherein the portable apparatus is a portable navigation apparatus.

5. An electronic system having a portable apparatus and an electronic apparatus to which the portable apparatus is attachable, the electronic system comprising:

a first connecting line provided in the portable apparatus;

a second connecting line connected to the first connecting line and provided in the electronic apparatus;

a detector provided in the electronic apparatus and detecting an attachment of the portable apparatus by use of the first connecting line and the second connecting line, when the second connecting line is electrically connected to the first connecting line, and detecting a detachment of the portable apparatus by use of the first connecting line and the second connecting line, when the second connecting line is electrically disconnected from the first connecting line; and

a reset transmitter provided in the electronic apparatus and transmitting a reset signal to the portable apparatus through the second connecting line and the first connecting line, the reset signal initializing an operation of a microcomputer of the portable apparatus.
