Abstract
One example includes a device that is comprised of a cover housing, a reflective sheet, a coupler, and a fastener. The reflective sheet may hold media against a planar transparent scanning area of the device. The coupler may removably attach the reflective sheet to the cover housing, the coupler having a resilient member to exert an axial restoring force between the reflective sheet and the cover housing. The fastener may fix the coupler to the reflective sheet.
Claims15
A device, comprising:
- a cover housing;
- a reflective sheet to hold media against a planar transparent scanning area of the device;
- a coupler to removably attach the reflective sheet to the cover housing, the coupler having a conical spring to exert an axial restoring force between the reflective sheet and the cover housing, the conical spring to constrain movement of the coupler and enabling movement thereof in an axial direction that is substantially perpendicular to the surface of reflective sheet;
- and
- a fastener to fix the coupler to the reflective sheet.

A device, comprising:
- a cover portion including a cover housing, a reflective sheet to hold media against a transparent scanning area of a photocopier, a plurality of couplers to removably attach the reflective sheet to the cover housing, each of the plurality of couplers having a conical spring to exert an axial restoring force between the reflective sheet and the cover housing, and a fasteners to fix each of the plurality of couplers to the reflective sheet, respectively, the conical springs to constrain movement of the coupler and enabling movement thereof in an axial direction that is substantially perpendicular to the surface of reflective sheet;
- and
- a scanning base portion attached to the cover portion, the scanning base portion having an optical scanning mechanism to optically scan media placed on the scanning base portion between the reflective sheet and a planar transparent scanning area of the scanning base portion.
A device comprising:
- a cover housing including a plurality of apertures;
- a reflective sheet of pliant material having a reflective surface to hold media against a planar transparent scanning area of the device;
- a plurality of detachable couplers, each of the detachable couplers comprising:
- a base having a planar contact surface;
- a set of legs extending axially and perpendicularly from a central portion of the base to terminate in an outwardly protruding portion thereof, each outwardly protruding portion including a chamfered leading edge that resides within a respective aperture of the cover housing;
- and
- an outer tapering sidewall portion that tapers radially and inwardly from the outwardly protruding portion in a direction of its base to provide a trailing taper along each of the legs to facilitate removal of the respective detachable coupler from the respective aperture;
- a plurality of springs having an elongated conical shape extending axially from one end having a larger diameter to terminate in another end having a smaller diameter, each of the plurality of springs being coaxial with and circumscribing an associated set of legs of a respective detachable coupler with its larger diameter end engaging the cover housing and its smaller diameter end engaging a base of a respective detachable coupler to exert an axial restoring force between the cover housing and the base of the respective detachable coupler, and movement of each detachable coupler being constrained to move in the axial direction that is substantially perpendicular to the surface of the reflective sheet;
- and
- a plurality of fastening elements to fix each of the plurality of detachable couplers to the reflective sheet.
