<p>PURPOSE:To always permit the smooth taking out of a cassette, by constituting of a low stalling section by coating a grease oil between a stalling shaft, and a gear having rotating allowance for the shaft. CONSTITUTION:When the stopper of a cassette holder 3 is released in a state that a cassette tape 11 is loaded on a mechanism 6, the cassette tape 11 held with a cassette pressing spring, and a cassette half guide 10, is started to be taken out of the mechanism 6 by the force of a cassette holder releasing spring 12. And simultaneously when the cassette tape 11 is separated from the mechanism 6 completely, the low stalling section of a stalling device is finished. The gear 2 is not engaged with a turning stalling shaft 17 until then, and the gear is rotated in a low stalling force state by the viscosity of the grease oil. And when the gear 2 is engaged with the stalling shaft 17, a high stalling force due to the viscosity of a sealed grease oil is started to act, and the force is transmitted from the gear 2 to the cassette holder 3, thereby, the holder continues to open at constant speed.</p> |
