Abstract
A cassette tape recording and/or reproducing apparatus has a head base assembly comprised of a first arm mounted, at one end, on the chassis for swinging about a first axis perpendicular to a plane on which a cassette is located on the chassis, a second arm connected in end-to-end relation to the other end of the first arm by a joint structure permitting relative angular displacements about a second axis parallel to the first axis, and a fixed guide post extending parallel to the plane of the chassis and passing slidably through a slot in the second arm for stabilizing the position of a magnetic head on the second arm in respect to a cassette on the chassis. The joint structure includes a screw defining the second axis and being turnable to relatively displace the connected ends of the arms along that second axis for rocking the second arm about the fixed guide post and thereby varying the aximuth angle of the head.
