ABSTRACT:
A rotary head assembly for use in a tape recording/reproducing apparatus. The rotary head assembly comprises a head base, a drum holder affixed to the head base, a recording/reproducing head, a head carrying drum, a sector gear pivotably mounted to said drum holder, a slide member mounted on the head base for sliding movement, and means for interlocking said slide member with said sector gear. The head carrying drum is rotatably received in a cylindrical bore formed in the drum holder and carries the recording/reproducing head at one end and a coaxial gear at the other end. The sector gear is arranged to mesh with the coaxial gear. The slide member is slidingly moved to pivot the sector gear through the inter-locking means a sufficient angle to rotate the gear on the head carrying drum an angle of substantially 180 degrees in response to the reversal of the recording/reproducing operation between the forward and the reverse directions.
