<p>PURPOSE:To prevent the occurrences of a damage on a video cassette recorder or a cassette by prohibiting the action of a cassette insertion means at a time when an automatic stopping mechanism is operated in case of an abnormality. CONSTITUTION:If an abnormality happens in a VTR 10 and the automatic stopping function is operated, the output of an automatic stoppage detection circuit 23 is returned to '1'. Then an automatic stoppage displayer 28 is dis played by blinking, and at the same time, the output of an AND gate 25 goes to '0', and a FWD input to a motor driver circuit 22 goes to '0' at all time, and further, a cassette loading/unloading motor 1 rotates in the cassette unloading direction and does not rotate in the insertion direction, thus the inser tion action of a cassette is prohibited. As a result, damages that may happen on a video cassette recorder or a cassette at the generation of abnormality, can be prevented.</p> |
