開く信号ｇを送る。パネルカバー制御回路８は信号ｇに
基づいてパネルカバー駆動機構５に駆動指令を発する。In the embodiment, when the loading control circuit 7 receives a command to take out the cassette using the loading control signal a, it detects the open/closed state of the panel cover 4 based on the panel cover open/closed state signal sent from the panel cover drive mechanism 5. . If the panel cover 4 is open, the loading control circuit 7 outputs a cassette ejection control signal C to the loading mechanism 6. If the panel cover 4 is closed or in an intermediate position, the loading control circuit 7 sends a signal g to the panel cover control circuit 8 to open the panel cover 4. The panel cover control circuit 8 issues a drive command to the panel cover drive mechanism 5 based on the signal g.

り外部に搬出する。The panel cover drive mechanism 5 receives the drive command, opens the panel cover 4, and outputs a signal to the loading control circuit 7. The loading control circuit 7 outputs a control signal C to the loading mechanism 6 when it is confirmed that the panel cover 4 is opened based on the signal. Loading mechanism 6
Based on the control signal C, the cassette is carried out from the cassette outlet 2.

開閉動作を一時停止させる。Conversely, when the panel cover control circuit 8 receives a command to close the panel cover 4 through a control signal while the panel cover 4 is open, the panel cover control circuit 8 receives a signal sent from the loading control circuit 7 that prohibits closing the panel cover. g, the panel cover control circuit 8 does not send the control signal d for opening the panel cover 4 to the panel cover drive mechanism 5. Further, the panel cover drive mechanism 5 outputs a current signal e of the built-in drive motor to the overcurrent protection circuit 9. The overcurrent protection circuit 9 outputs an abnormality signal f when the current signal e is an overcurrent value.
is output to the panel cover control circuit 8. When the panel cover control circuit 8 receives the abnormal signal f, it outputs a stop control signal d to the panel cover drive mechanism 5, stops the drive motor of the panel cover drive mechanism 5, and stops the opening/closing operation of the panel cover 4. make it pause.
尚、実施例ではビデオカセットレコーダに適用した場合
について説明したが、これに限らず、光デイスクプレー
ヤ等に同様に適用できるものである。Incidentally, in the embodiment, a case where the present invention is applied to a video cassette recorder has been described, but the present invention is not limited to this and can be similarly applied to an optical disc player or the like.

防止できるという効果を有する。As explained above, in the present invention, the operation of the loading mechanism that opens the ejection hole for cassettes etc. is linked with the operation of the panel cover opening/closing mechanism, so that the procedure of opening the panel cover when taking out the cassette etc. can be omitted,
It also has the effect of preventing accidents such as the cassette getting caught on the panel cover.
