Abstract
An automatic edge guide assembly comprises a sheet feeding mechanism, a slide housing mounted within the sheet feeding mechanism and an edge guide slidably connected to the slide housing. The edge guide is biased by a first biasing force and a second biasing force, wherein the first force is greater than the second force, allowing for automatic edge alignment within a predetermined range of widths.
Claims27
An edge guide assembly for a peripheral device, comprising:
- a peripheral device, said peripheral device having an opening for receiving media sheets within a preselected size range comprising a first side and a second side opposite said first side;
- said first side of said opening comprising a stationary guide member;
- said second side of said opening comprising:
- a slide housing having upper and lower collars;
- an edge guide having upper and lower posts extending through said upper and lower collars, respectively;
- and
- an upper spring disposed about said upper post and a lower spring disposed about said lower post, said upper and lower springs disposed between said slide housing and said edge guide for biasing said edge guide toward said stationary edge member.
In a peripheral device having a media input for receiving a media stack, said media input having at least two sides, an edge guide assembly for aligning edges of said media stack, comprising:
- a stationary slide housing and an edge guide disposed in one of said sides of said media input;
- said edge guide being slidably disposed relative to said slide housing;
- said slide housing having at least one collar axially aligned with at least one post extending from said edge guide;
- and
- at least one spring disposed between said edge guide and said slide housing for biasing and slidably disposing said edge guide relative to said slide housing.
An edge guide assembly, comprising:
- a media pick mechanism;
- a slide housing mounted within said media pick mechanism;
- an edge guide slidably connected to said slide housing;
- said edge guide biased by a first biasing force and a second biasing force, wherein said first force is greater than said second force.
