<p>PURPOSE:To achieve soft ejection by turning a large-gear lever when a pinion is engaged with a large gear, and moving back a head chassis and a pinch roller, and ejecting a cassette by lifting a cassette lever. CONSTITUTION:The titled mechanism is designed to have large-gear lever 8 presses up a head chassis 10 in the leading state of successive rotation to move back a pinch roller P and a head H by about 7mm., and lifts a cassette lever 12 in the trailing stage. When a cassette lever support 14 moves under the cassette lever 12 to spring off a cassette with the cassette lever support 14, a pinion lever 4 is kicked to disengage pinions 3' of a couple of pinions 3 from a large gear, thereby ejecting the cassette. In this case, only about 200g pressure is required to press a lever 6 and the pressure reduced to about 1/10 conventional one.</p> |
