Title: Head loading mechanism
Inventor: SEDOU TOKIYUKI
IPC: G11B5/54
Filed: 1982-03-08
Abstract: PURPOSE:To easily adjust the interval between the upper and lower magnetic heads, by setting the 1st and 2nd cams installed to the 1st and 2nd swing arms which make both sides loading, respectively, under a freely adjustable condition. CONSTITUTION:This mechanism is composed of a cam a2 installed to the end part of an upper swing arm 2 and another cam (b) installed to the end part of a lower swing arm 1. The cam (b) on the arm 1 can be moved in the direction in which the cam (b) approaches or goes away from the cam a2, and can be fixed at a desired position. The mechanism of the fixation of the cam (b) is made in such a way that the part of the mechanism which is tied to the swing arm 2 is pushed from the side by a screw or the part of the cam (b) which is fitted to the swing arm 2 is passed through the swing arm 2 in the longitudinal direction and fixed by a screw. When this mechanism is applied, the interval between the upper and lower magnetic heads can be adjusted extremely easily.
