Patent ID: 8270113

Claim:
A magnetic head cleaning mechanism employing a threading system comprising a threading arm which transports a leader pin disposed at a tip end of a magnetic tape wound on a supply reel up to a take-up reel, the threading arm transporting the magnetic tape through a threader track, magnetic head cleaning mechanism characterized by comprising: a magnetic head for magnetically writing and reading data on and from the magnetic tape; a cam gear arranged on a side of the magnetic tape relative to the threader track for driving the threading arm; an arm mechanism including a cleaning member; and a base member for supporting the arm mechanism, the arm mechanism comprising: a cleaning-side arm section including the cleaning member disposed at a first end thereof; a support-side arm section including a first end which rotably and pivotally supports the cleaning-side arm section and a second end which is rotably and pivotally supported by the base member, the base member comprising a guide section to guide a moving path of the cleaning member; the cleaning-side arm section comprising an engage section which engages with the guide section and which is movable along the guide section; the support-side arm section being moved, when the cam gear rotates up to a predetermined position, by pushing pressure from the cam gear; the guide section being formed to guide the moving path of the cleaning member such that the cleaning member moves through the moving path from a standby position on a side of the magnetic head relative to the threader track toward the threader track and thereafter moves from the threader track toward the magnetic head, to thereby reach a predetermined cleaning position in front of the magnetic head.
