Next, a first example of the operation will be described with reference to FIG.

The microcomputer 30 constantly monitors the accessory power supply (hereinafter referred to as the Acc power supply). When the Acc power supply is turned off (S1), the switch 20 checks whether the medium is in the main body (S2). .

If there is a medium in the main body, then switch 22
It is checked whether the operation unit 3 has been removed from the operation unit holder 4 (S3). This check is performed for 10 seconds (S4). If it is not removed within 10 seconds, it is checked by the switch 23 whether the operation unit holder 4 is in the closed state (S5), and if it is closed, the slide plate 12 is slid forward by a motor (not shown) to open. (S6).

After the opening state, or when the operation section is originally opened in (S5) and when the operation section is removed in (S3), the cassette in the main body is ejected by driving the loading / ejection motor 25. (S7). When the ejection is completed by the detection of the switch 21, the timer is started (S8). Here, within 10 seconds, it is checked whether or not the cassette is removed from the insertion slot 2 by detecting the switch 19 (S9). If the cassette is not removed, the cassette in the insertion slot 2 is driven into the main body by driving the motor 25 (step S9). S10). Also (S
If the medium is removed in step 9) or loaded in step S10, the switch 23 checks whether the operation unit holder 4 is in the closed state (S11).

As described above, if the recording medium is in the main body at the time of acc-off, the recording medium is ejected once.

If the medium is not removed from the insertion slot within a predetermined time in the eject state, the recording medium is reloaded again.

The operation of the second example will be described with reference to FIG. In the second embodiment, the medium is ejected when the operation unit is removed while the Acc power supply is turned off (within a predetermined time after the power is turned off). If the operation unit is removed at any time, such as the power-on state and the Acc power-off state, the recording medium is ejected if the recording medium is in the apparatus.

The operation will be described below with reference to the flowchart of FIG. The microcomputer 30 always checks the operation unit detection switch 22 irrespective of whether the Acc power is on or off (S20).
When it is detected as 0 (S21), an ejection process of the recording medium is executed (S22). Then, the ejection is completed and the recording medium is ejected by the switch 19 (S
23) Then, the timer is started (S24).
In step S21, it is determined that there is no recording medium in the apparatus main body and the recording medium is present in the insertion slot by the switch 19 (S2).
5) When this is done, the process also enters (S24).

Then, it is checked whether the recording medium is removed from the insertion slot by the switch 19 within 10 seconds (S
26) If the recording medium is not removed, the reloading process (S27) is performed, and the recording medium is stored in the apparatus. (S2
When reloading is completed in step 6) or whether the operation section holder supporting the operation section is closed (S28), the switch 24 checks whether the operation section holder is closed (S28). If the operation section holder is open, the operation section holder is closed (S29) and the processing ends. .

As an effect of the second example, since removing the operation unit when the Acc power is turned on means leaving the car, the Acc power is turned off sooner or later, so that recording is performed earlier. Media can be ejected.

In the first example, when the Acc power supply is off, once the reload is performed, it is necessary to turn on the Acc power supply again in order to remove the recording medium later. Since the recording medium can be ejected, the key operation of the car can be eliminated.

[0029]

As described above, according to the present invention, the operation unit is removed and the recording medium is automatically ejected when the vehicle is powered off, so that the recording medium remains in the main body. It is possible to prevent the recording medium from being stolen together with the main body, and to prevent the recording medium from being stolen. Further, after the operation unit is removed, the recording medium inside the apparatus is ejected at the timing of turning off the Acc power, so that it is possible to prevent interference such as collision between the recording medium and the operation unit.
Further, in the case of the second invention, when the recording medium is ejected and left without being removed from the insertion slot, the recording medium is reloaded into the apparatus within a predetermined time from the ejection, and the recording medium is ejected. Can be prevented from being exposed to the interior of the vehicle to prevent theft, and at the same time, the recording medium can be prevented from being directly irradiated with sunlight.
