Title: Cassette storing device
Inventor: OKUMURA YUUJI
IPC: G11B15/675
Filed: 1983-06-09
Abstract: PURPOSE:To keep a fixed level of pressing force and to improve the operability by distributing a rotary lever interlocking the movement of a cassette holder and a spring which energizes the rotary lever in the cassette ejecting direction so that the distance is reduced between the rotary lever and and a rotary shaft during a cassette inserting operation although the spring force is increased. CONSTITUTION:Immediately after the cassette loading is started and immediately before loading is through with the cassette, the force of a coil spring 33 is referred to as F1 and F1' together with arm length L1 and L1' of the moment acting on the 4th rotary lever 32 and the component force F4 and F4' of the guide groove directon of the force F3 and F3' acting on the 1st guide roll 6g. When both states are compared with each other, F1<F1' is satisfied for the spring 33 together with L1>L1' with the arm length of the moment. Therefore F4 F4' is satisfied. The pushing force of a cassette is equal to the resistance force of F4 and F4'. Thus an approximately fixed level of pressing force is secured from the start to the end of a cassette loading action.
