<p>PURPOSE:To make only a take-up reel base rotatable during loading and unloading operations, by turning a back tension lever to the operating position simultaneously with the start of loading to engage a brake band with a supply reel base. CONSTITUTION:The second turning lever 25 is turned counterclockwise and a back tension pin 21 is placed in the notch of a cassette 5, therefore, a brake band 24 is separated from a supply reel base 14. A pinch roller 7 is placed in the notch of the cassette 5 also. Meanwhile, the third and the fourth turning levers 30 and 31 are turned counterclockwise, and an end sensor 29 of the side of a tape to be take-up faces a tape 4. An eject lock lever 36 is placed in the position to which the lever 36 is turned counterclockwise because a projecting pin 3g of a loading disc 3 is engaged with an engaging piece 36b, and the lock of a slide lever 35 is released; and therefore, the eject operation is possible only at this time.</p> |
