Abstract: PURPOSE:To improve operability by devising the stretching structure of a limiter spring, obtaining the press-bonding force of a head drum to a tape cassette with the limiter spring and preventing the limiter spring from becoming a load at the time of moving a head drum moving lever to a retreat position. CONSTITUTION:A play lever 83 is constituted of a main lever 84 which can freely slide and a sub lever 94 which can freely slide and turn with respect to the lever 84, and a return spring 100 and the limiter spring 101 are stretched to be disposed between the main lever and the sub lever and between the sub lever 94 and the head drum moving lever 79 respectively. When the main lever 84 is pushed in, the sub lever 94 is integrally moved and the limited spring 101 extends. and when the head drum moving lever 79 moves to the retreat position, the sub lever 94 is integrally moved and only the return spring 100 extends. Thus, the tensile force of the limiter spring 101 acts to make the head drum press-bond to the tape cassette and the tensile force of the return spring 100 acts to return the head drum moving lever 79 to the initial position. Thus, an operating touch is made light.

Title: Friction member
Inventor: YOSHIMURA TATSUYA
IPC: F16D69/00
Filed: 1998-01-23
Abstract: PROBLEM TO BE SOLVED: To prevent local wear of a friction member which makes frictional sliding contact with a disk rotor. SOLUTION: A friction member 1 joined integrally with one side of a back plate 4 and used while in sliding contact with a mating rotor has at its front a porosity adjustment part 2 where porosity is smaller than at its rear, along the direction X to make sliding contact with the mating rotor. The porosity adjustment part 2, although making frictional sliding contact with the mating rotor in such a way that it is trapped in the mating rotor during braking, allows the surface of the friction member to wear evenly, since the degree of wear is kept smaller at the front than at the rear through the adjustment of the porosity.
