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.
Claims18
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;
- at least one permanent magnet attached to the second grip member;
- the print media holder device having an outer dimension that is defined as a distance from an outermost portion of the first grip member to an outermost portion of the second grip member;
- and
- an electromagnet 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.

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;
- the print media holder device having an outer dimension that is defined as a distance from an outermost portion of the first grip member's grip edge to an outermost portion of the second grip member's grip edge;
- and
- a second magnet disposed between the first and second grip edges;
- where at least one of the second magnet and the grip member magnet comprises an electromagnet that is selectively energized in a manner that generates repelling forces between the grip member magnet and the second magnet such that the first and second grip edges pushed outward by magnetic force in a manner that increases the outer dimension of the print media holder device to grip a media core.
4 more elements
A print media holder device, comprising:
- a plurality of grip members, each having a grip edge;
- a plurality of grip member magnets, each 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;
- where 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 forces between the grip member magnets and the central magnets such that the grip edges are pushed outward by magnetic force in a manner that increases the outer diameter of the print media holder device to grip a media core.
