<p>PURPOSE:To prevent damages to a tape by pulling out the tape when a cassette lowering detection switch is ON and ejecting the tape when it is OFF. CONSTITUTION:A lever 8 is moved by the rotation of a loading motor and a cassette 1 is descended along an L groove 3a. Then, the point of time when a lowering is completed is detected by the on/off toning of a cassette lowering detection switch 100. When an operation is normal, after the switch 100 is turned ON, a cassette loading completion switch 9 is turned ON. Then, after a lapse of specified time, when observing the switch 100 and finding it in an ON-condition, the tape pulling out operation is continued. At the time of operational abnormality, when the switch 100 18 found not to be turned ON after the switch 9 is turned ON, the loading motor is reversely rotated and the cassette 1 is ejected.</p> |
