Abstract
In a head rotation mechanism in an auto-reverse type tape player, the head rotation mechanism comprising a sector gear engaging with a cam gear provided on a head lead side of a rotary head; a boss extending in the direction opposite to the rotary head side of the sector gear and having a tapered foreend; and a link mechanism for rotating the head. The link mechanism is rocked by the cam gear and equipped with a U-shaped member engaging with the boss on the sector gear. The boss on the sector gear engages with the U-shaped member of the link mechanism for rotating the head only when the rotary head is located at a release position, and the boss is out of contact with the U-shaped member when the rotary head is located ahead of the release position, whereby a reversible rotation of the single cam gear is used to change a direction of the rotary head and move the head forward.
