Abstract
A print media holder device has first and second grip members. Permanent magnets are attached to the first and second grip members. An electromagnet is disposed between the first and second grip members, where when the electromagnet is selectively energized the permanent magnets attached to the first and second grip members are repelled in a manner that increases the outer dimension of the print media holder device to grip a media core.
Claims21
A print media holder device, comprising:
- a first grip member;
- at least one permanent magnet attached to the first grip member;
- a second grip member;
- and
- an electromagnet disposed between the first and second grip members, wherein, when the electromagnet is selectively energized, the permanent magnet attached to the first grip member is attracted or repelled in a manner that reduces or increase an outer dimension of the print media holder device.
2 more elements
A print media holder device, comprising:
- a first grip member having a first grip edge;
- a first grip member magnet attached to the first grip member;
- a second grip member having a second grip edge;
- and
- a second magnet disposed between the first and second grip edges;
- wherein at least one of the second magnet and the grip member magnet comprises an electromagnet that is selectively energized in a manner that generates attractive forces or repulsive forces between the grip member magnet and the second magnet such that the first grip edge is pushed inward or outward by magnetic force in a manner that reduces or increases an outer dimension of the print media holder device.
3 more elements
A print media holder device, comprising:
- a plurality of grip members, each having a grip edge;
- a plurality of grip member magnets attached to one of the grip member;
- the print media holder device having an outer diameter that is defined as distance from an outermost portion of a first grip member edge;
- and
- a plurality of central magnets disposed at a central location with respect to the plurality of grip members;
- wherein at least one of the central magnets and the grip member magnets comprises an electromagnet that is selectively energized in a manner that generates repelling or attractive forces between the grip member magnets and the central magnets such that the first grip member edge is pushed outward or inward by magnetic force in a manner that increases or decreases the outer diameter of the print media holder device to grip a media core.
