Abstract
In one example an input tray is disclosed. The input tray has a support surface, at least one media guide and an over-center device. The media guide is movable between a first position and a second position. The over-center device forces the media guide towards the first position when the media guide is closer to the first position than to the second position and forces the media guide towards the second position when the media guide is closer to the second position than to the first position.
Claims14
An input tray, comprising:
- a support surface to hold a stack of media;
- at least one media guide positioned on top of the support surface and movable between a first position and a second position, the first position for media of a first width and the second position for media of a second, different width;
- a second media guide movable between a third position and a fourth position, the second media guide attached to the at least one media guide with a coupling device such that the second media guide moves in an opposite direction from the at least one media guide when the at least one media guide moves between the first position and the second position;
- and
- a first over-center device mounted to the input tray and coupled to the at least one media guide to force the at least one media guide towards the first position when the at least one media guide is closer to the first position than to the second position and to force the at least one media guide towards the second position when the at least one media guide is closer to the second position than to the first position.
A device, comprising:
- at least one input tray to support a stack of media sheets;
- a pair of media guides positioned in the at least one input tray and movable between respective first and second positions, the first position for media of a first width and the second position for media of a second, different width;
- a coupling device connecting the pair of media guides together such that the pair of media guides move towards or apart from each other when moving between the respective first and second positions;
- at least one over-center device coupled to one of the pair of media guides, the at least one over-center device to force the pair of media guides apart when the pair of media guides are in the first position and to force the pair of media guides together when the pair of media guides are in the second position.
A method of adjusting a media guide, comprising:
- moving the media guide, against a spring force acting in a first direction, from a first position for a first media width towards a second position for a second, different media width;
- wherein the media guide is coupled to a second media guide that is movable between a third position and a fourth position, the second media guide being attached to the first media guide with a coupling device such that the second media guide moves in an opposite direction from the first media guide when the first media guide moves between the first position and the second position;
- and
- switching the action of the spring force to a second direction, opposite the first direction, using an over-center device, when the media guide reaches a location closer to the second positions than to the first position.
