<p>PURPOSE:To miniaturize a housing case without especially providing a cassette presence or absence detecting switch by detecting the presence or absence of the cassette by rotating a reel when a dew drop is detected at the time of housing a cassette. CONSTITUTION:When the storage of a cassette holder is detected, the dew drop is detected by a dew drop detecting sensor 10. When the dew drop is not detected, a load motor driving circuit 9 is operated in order to operate a loading. When the dew drop is detected, a reel motor is rotated clockwise, and whether or not a winding reel 15 is rotated is detected after almost 1 sec. When the rotation of the winding reel is not detected, the reel is stopped without operating the loading in order to prevent a tape from winding round a rotary drum 2, and it is necessary to wait for an eject key to be pressed down. On the other hand, when the rotation of the reel is detected, it is noticed that the cassette tape is not still loaded, and that the reel idles, and then the reel is stopped, and the loading operation is operated.</p> |
