Abstract:
1. A magnetic head cleaning mechanism, comprising: a threading arm for transporting a leader block, which can be engaged with a leader pin disposed at a tip end of a magnetic tape wound around a supply reel, engaging the leader block with the leader pin, and drawing the leader block engaged with the leader pin; a magnetic head for reading data from and writing data on the magnetic tape by using magnetic force; a brush link arm comprising a cleaning member at a tip end thereof, the brush link arm being supported to be able to rotate, and a cam gear for driving the threading arm, the cam gear being disposed on a side of the magnetic head relative to a track of a threader as a route to transport the magnetic tape, wherein the brush link arm is at a position on a side of the magnetic head relative to the threader track in an ordinary state and the brush link arm rotates, when the leader block is transported to a position near the leader pin, in association with rotation of the cam gear to thereby bring the cleaning member into contact with the magnetic head on the threader track, and wherein the brush link arm rotates in a plane parallel to a rotational plane of the cam gear.
