21.

[0031]

Referring

to

FIGS.

4A

and

4B,

an

indicator

27,

Which

is

formed

by

a

light

emitting

device

such

as

an

LED,

is

arranged

on

an

eXternal

surface

22a

of

the

key

cover

22.

The

indicator

27

is

electrically

connected

to

the

key

con

troller

23,

as

shoWn

in

FIG.

indicate

that

the

portable

device

5

is

in

a

state

held

in

the

holder

21

or inserted

in

the

key

receiver

21a.

In

the

preferred

embodiment,

the

indicator

27

is

continuously

illuminated

if

the

portable

device 5

is

held

in

the

holder

21

When

the

engine

is

running.

If

the

portable

device

5

is

held

in

the

holder

21

or

inserted

in

the

key

receiver

21a

When

the

engine

is

not

running,

the

indicator

27

?ashes

and

a

buZZer

(not

shoWn)

goes

off.

[0032]

The

key

veri?cation

unit
