Patent ID: 8537491

Claim:
A magnetic tape apparatus comprising: a motor configured to perform a forward rotation and a backward rotation, reel a magnetic tape during one of the forward and backward rotations, and feed the magnetic tape during the other of the forward and backward rotations; a roller guide configured to adjust a travelling direction of the magnetic tape while the magnetic tape is fed by a roller; a head configured to perform read and write of data on the magnetic tape the travelling direction of which is adjusted by the roller guide; a blade arranged on a rotatable shaft of the motor and configured to rotate in conjunction with a rotation of the motor; a first suction tube that serves as a tube that couples the blade with an edge part of the roller of the roller guide and has a blade side opening area at a location where air is sucked by the blade during the forward rotation; a second suction tube that serves as a tube that couples the blade with the edge part of the roller of the roller guide and has a blade side opening area at a location where air is sucked by the blade during the backward rotation; a shutter unit configured to perform opening and closing of the first and second suction tubes; and an opening and closing control unit configured to control the shutter unit to open the first suction tube during the forward rotation and open the second suction tube during the backward rotation.
