Abstract
A cassette player or recorder having a device for adjusting the azimuth angle of a read head during playback. An azimuth angle adjusting member is controlled by two pulling strings for moving the member in opposite directions, the strings being separately tensioned, and being moved by a correction knob on the front panel of the apparatus.
Claims6
A magnetic tape player, comprising:
- a frame having an accessible location for controls,
- a magnetic read head, and
- means for mounting the magnetic read head for scanning magnetic signals on magnetic tape in the player, said mounting means including an azimuth-angle correction device for correcting an incorrect azimuth-angle position of the read head relative to a track on the magnetic tape, said correction device comprising a pivoting plate mounted pivotably relative to said frame, the magnetic head being carried on the pivoting plate and arranged so that pivoting of the plate affects the azimuth-angle position of the head, and a movable pivoting member arranged for pivoting said plate responsive to movement of said member,
- characterized in that the azimuth-angle correction device further comprises a manually operable correction knob movably mounted to said frame at said accessible location,
- two transversely flexible tension members each having first and second ends, each being connected near the respective first end to the correction knob and near the respective second end to said pivoting member, respectively arranged to couple movement in opposite respective directions of the correction knob to the pivoting member, and
- resilient means for tensioning said two tension members at said first ends so as to prevent slackening of the tension members, whereby lost motion in the azimuth-angle correction device is eliminated.
