Mechanism for lifting and lowering magnetic head in magnetic recording and reproducing device
First Claim
1. A mechanism for lifting and lowering a magnetic head in a magnetic recording and reproducing device, comprising:
- (i) a frame;
(ii) a first guide shaft supported on said frame, and a second guide shaft rotatably supported on said frame and having an eccentric portion;
(iii) a magnetic head carriage supporting a magnetic head thereon and slidably movable along said guide shafts toward a recording/playback position, drive means operably connected to said carriage for sliding said carriage along said guide shafts, said magnetic head carriage having an end held in engagement with said eccentric portion of said second guide shaft.(iv) a positioning plate mounted on said frame; and
(v) a driver mechanism mounted on said frame for rotating said second guide shaft to cause said eccentric portion to display said magnetic head carriage and rotate said magnetic head carriage about said first guide shaft toward said positioning plate whereby a magnetic medium interposed between said positioning plate and said magnetic head permits transducing contact between a magnetic medium and said magnetic head.

Abstract
A mechanism for lifting and lowering a magnetic head into and out of contact with a magnetic medium such as a magnetic sheet includes at least one guide shaft rotatably supported on a frame and having an eccentric portion. A magnetic head carriage supports a magnetic head thereon and is slidably movable along the guide shaft toward a recording/playback position, the magnetic head carriage having an end held in engagement with the eccentric portion of the guide shaft. A driver mechanism is mounted on the frame for rotating the guide shaft to cause the eccentric portion to displace the magnetic head toward a backing plate with a magnetic medium such as a magnetic sheet interposed therebetween.
