Abstract

PURPOSE: To gently and closly open the cassette cover by providing a braking means to a cassette cover opening means.
CONSTITUTION: A lever 4 is connected to an arm 3 which is driven by a coil spring 7 energizing a cassette cover 1 in its open direction and a gear 6a and vane wheel 6 making contact rolling with the friction material fitted thereto are disposed. The friction material of the lever 4 is pressure-contacted to the gear 6a by a coil spring 8. Then, if the lock pawl 12 of mechanism part is disengaged from a locking stopper piece 1d, the arm 3 is turned by the action of the coil spring 7, then the vane wheel 6 is turned by way of the cooperation of the lever 4 and the revolution of the gear 6a, by the air resistance developed whereby the rate of opening of the cassette cover 1 is decelerated and the cassette cover 1 opens slowly
