Magnetic head cleaning mechanism of threading scheme magnetic tape apparatus

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.
