Appl. No.:

09/792843

Inventors:

Michael Gustafson - San Diego CA

Assignee:

Hewlett-Packard Company - Palo Alto CA

International Classification:

B65M 352

US Classification:

Abstract:

A non-planar single sheet separator wall preferably inclined at about 25Â from the vertical away from a paper stack first engages the side corners of the leading edge of a sheet of paper or other media picked from the top of the generally horizontal or downwardly inclined stack by a roller or pusher and causes the corners of the sheet to first curl upwardly along the wall before the central portion of the leading edge of the sheet engages the central portion of the separator wall. The separator wall configuration substantially eliminates downward curling of one or both leading corners of a sheet which is purposely upwardly bowed by an elastomeric pad near the center of the separator wall to reduce multi-sheet picks and separator jams.

Abstract:

An electro-mechanical module comprises a packaged electrical part having a surface which dissipates heat, and a springy frame which overlies that surface. This frame includes a pair of fasteners for catching on the package at two predetermined locations, and the frame has an unstressed state in which the fasteners do not coincide with the two locations. However, the frame is springy enough to be stressed and thereby move the fasteners to the two locations, and thereafter return back towards the unstressed state and catch the fasteners on the package at the two locations. To complete the module, a heat sink rests on the surface and is removably attached to the frame.
