Abstract
A roll holder unit for a printer includes a regulating wall, a movable arm, and a lock arm. The regulating wall is located on the same axial side of the roll as the regulating wall to prevent axial movement of a roll. The movable arm moves between an adjacent position in which the axle is contact with a shaft and a spaced-apart position in which the axle is apart from the shaft. The movable arm is biased toward the adjacent position from the spaced-apart position. The lock arm moves between a regulating position in which the lock arm regulates the movable arm from moving from the adjacent position to the spaced-apart position and a release position in which the lock arm allows the movable arm to move from the adjacent position to the spaced-apart position.
Claims20
A roll holder unit for a printer, comprising:
- a regulating wall that regulates axial movement of a roll located on at least one axial side of the roll in opposing relationship with one axial end portion of the roll;
- a movable arm comprising an axle that supports the roll, the movable arm located on the same axial side of the roll as the regulating wall and configured to move between an adjacent position in which the axle is in contact with a shaft of the roll and a spaced-apart position in which the axle is apart from the shaft, the movable arm biased toward the adjacent position from the spaced-apart position;
- and
- a lock arm configured to move between a regulating position in which the lock arm regulates the movable arm from moving from the adjacent position to the spaced-apart position and a release position in which the lock arm allows the movable arm to move from the adjacent position to the spaced-apart position.
A roll holder comprising:
- a regulating wall located on at least one axial side of a roll;
- a movable arm located on the same axial side of the roll as the regulating wall, the movable arm comprising an axle movable between an adjacent position in which the axle engages the roll and a spaced-apart position in which the axle disengages the roll;
- and
- a lock arm that moves between a regulating position that prevents the movable arm from moving from the adjacent position to the spaced-apart position, and a release position in which the lock arm allows the movable arm to move from the adjacent position to the spaced-apart position.
A method for securing a roll in a roll holder, the method comprising:
- restricting axial movement of the roll with a regulating wall located on at least one axial side of the roll;
- engaging the roll with a movable arm located on the same axial side of the roll as the regulating wall, the movable arm comprising an axle movable between an adjacent position in which the axle engages the roll and a spaced-apart position in which the axle disengages the roll;
- and
- locking the roll into position with a lock arm that moves between a regulating position that prevents the movable arm from moving from the adjacent position to the spaced-apart position, and a release position in which the lock arm allows the movable arm to move from the adjacent position to the spaced-apart position.
