  • Patent number: 11942109
    Abstract: In order to enable adjustment of the inclination of a guide roller member with respect to a base body, this member is provided with a base body and a guide roller member that is secured to the base body and that determines the advancement direction for a prescribed tape. The guide roller member includes a base part and a rotating shaft that is secured to the base part. In relation to the base body, the base part comes into contact, simultaneously and on the same side as the rotating shaft, with: the leading ends of a plurality of screws that are passed through a plurality of screw holes penetrating the base body; and projecting parts that are connected to or have come into contact with the base part.

  • Patent number: 11393504
    Abstract: A magnetic tape device includes: a magnetic head; a head actuator that holds the magnetic head; and a tape lifting mechanism including a lifter arm. The lifter arm comes into contact with the magnetic tape to separate a magnetic tape from the magnetic head. The tape lifting mechanism moves the lifter arm in a push-out direction in conjunction with the head actuator moving in a first direction. The tape lifting mechanism moves the lifter arm in a retreating direction in conjunction with the head actuator moving in a second direction. The lifter arm pushes out the magnetic tape to separate the magnetic tape from the magnetic head, in response to the lifter arm moving in the push-out direction. The lifter arm separates from the magnetic tape to bring the magnetic tape into contact with the magnetic head, in response to the lifter arm moving in the retreating direction.

  • Patent number: 8270113
    Abstract: In a magnetic head cleaning mechanism applicable to a magnetic tape apparatus using a threading system, a cleaning member is placed at a cleaning position with high precision without excessively pushing the cleaning member. For this purpose, an arm to move a cleaning bristle to clean a magnetic head is disposed at a position on a side of the magnetic head relative to a threader track. The bristle moves through a moving path guided by a cam groove. The bristle first moves toward the threader track and then toward the cleaning position in front of the magnetic head. During the movement to approach the magnetic head through the moving path, the bristle does not exceed the cleaning position.
