'he removal 'nstruction devi.ce includes the mother case 1, the connector la provided on the rear surface of the -; 0 audi apparatus body, a battery 11, an ACC, voltage output circuit which is turned on and outputs an ACC voltage Vacc when a key of the vehicle is turned in a clockwise direction beyond the ACC, position, a bat.ery voltage monitoring circuit 1.7 for monitoring a battery voltage Vb and thereby detecting when the -ery voltage assumes a low level, a rise/fall batt detecting circuit 14 for detecting rse and fall of Itage Vac- vo the Al, -, a timer 15, and a controller 116, which controller is typically a microcomputer which executes various controls. The controller may K1 529 I output an alarm signal AL to give an instruction for removal of an audio apparatus for a predetermined period of time Tb (= seven seconds) a predetermined time Ta (= two seconds) after the ACC voltage Vacc has assumed a low level while the battery voltage Vb is at a high level.
The removal instruction device further includes an oscillation circuit 17 for generating a pulse train such as that shown in Fig 2 while the a-'arm signal AI. is being generated, a driver 18 for driving a buzzer by means of- the pulse train, a piezoelectric buzzer 19 for issuing an "alarm" sound, a seven-segment display portion 20a, such as an IED C." T," d-:s-7ny, and an operation -portion 2!')b.

'The alarm function can be turned on again by pressing the DX key for 2.5 seconds or longer. When the alarm function is turned off, the display portion -0 display shown in Pig. 3 (a) for 20a displays the of.
-0 Live seconds, and then returns to its previous display. When the alarm function is turned on, the display POrt-ion 20a displays the on display shown in Fig. 3 (b) for five seconds, and then returns to its previous display.
The operation of the removal instruction -h device shown in Fig. 1 will now be described wit reference to Fig. 4 which shows the waveforms of the ACC. voltage Vacc, the battery voltage Vb and alarm signa]- AL which is the removal instruction.
j I 1 1 K1 529 5- Immediately after the audio apparatus body 2 has been inserted into the mother case 1, the battery voltage Vb is at high level while the ACC voltage Vacc is at a low level (period tl).
The level of the ACC voltage Vacc rises when the key is turned to the ACC position in that state (period t2). The level of the battery voltage Vb and that of the ACC voltage Vacc fall when the key is further turned clockwise to start. the engine (starting period t3). 'This is done because starting the engine requires a large amount of energy for rotation of a sel motor or the llik-e. At that time, t S; uhe controll-er 16, which is de igne. to output an alarm s'----a'- A! which is an audio apparatus removal truction signal when the battery voltage Vb is at i ns. - - U ' a high level while the ACC voltage Vacc is at a low level, does notu output the alarm signal AL.
O' posi4.4 Returning the key to the 1. bion, W',Ch 4S -- L conducted after the eng-ine has been started, raises the le,;e! of the battery voltage Vb and that of the ACC voltage Vacc aga-n. 'Thereafter, this state is maintained so lonE as the vehicle is in motion (perod tL) or the vehicle's ignition is operating.
The level of the ACC voltage Vacc falls when the key is turned to the off position to stop the engine and thereby make the vehicle stop, whereby the controller 16 starts counting time and outputs a high-level alarm signal AL for Tb (= seven seconds) after Ta (= two seconds) has elapsed (an alarm generation perio-1 ',,5). Once the alarm signal AL has been generated, the oscillation circuit 17 outputs pulse trains shown in 'Fig. 2 to drive the piezoelectric buzzer 101 which issues an alarm sound through the driver 18.
K1 529 i In the alarm generation period t5, the controller 16 lowers the level of the alarm signal AL and thereby stops output of the alarm sound when the level of the ACC voltage Vacc rises because of the turning of the key or when no battery voltage Vb is input which occurs when the audio apparatus body is removed from the case 1.
While the vehicle is in motion or when the key is in the ACC position and, hence, while the f voltage Vb and that of the ACC level O.E the batt volta-e Vacc are at a high level, as in the case of a W period t4', the audio apparatus may be removed from the case 1. Removal of the audio apparatus brings t -or 1a and the connect the connect or 10 into disconnection. This drops the 'Level of the battery vc'-.'t,a,7e Vb and that of the ACC voltage Vacc (a removal period 5) - time, the controller 16 U - At that U does not output an alarm signal AL because the ACC 11 U - -L ki ' the battery vol+ a low vcl..aze Vacc an.

When the key is in the ACC position, the audio apparatus may be inserted into the mother case M-;s insertion br.; 1. T Lngs the connectors la and 1b into connection, and thus raises the level of the battery voltage Vb and that of the ACC voltage Vacc (period t7).
In the above-described embodiment, Ta is set to 2 seconds. However, Ta may be any period of time with which it takes for the driver to leave the vehicle. Also T1 may be 0.
As will be understood from the foregoing description, according to the present invention, the battery voltage and the ACC voltage are monitored, and an instruction for removing the vehicle-mounted apparatus is given and an alarm is issued by the
