US Patent:

42550440, Mar 10, 1981

Filed:

Jul 9, 1979

Appl. No.:

6/056129

Inventors:

Raymond G. Cormier - Nashua NH
Austin Davis - Nashua NH
Jacques Guiguizian - Haverhill MA
Leo O. Lutz - Hollis NH
Henry T. Pauk - Nashua NH

Assignee:

Nashua Corporation - Nashua NH

International Classification:

G03G 2100

US Classification:

355 15

Abstract:

Disclosed are blades oriented in a trailing configuration for cleaning residual toner from the photosensitive drums of photocopying machines without marring the drum's surface. In one embodiment of the invention, the blade is constructed of layers of resilient material having different moduli of elasticity resulting in the blade's having greater resistance to transverse deformation than to deformation along the primary axis of the blade. In another embodiment, the blade comprises a mass of an elastic material having a partially hollow interior. The hollow interior results in a blade with differing moduli of elasticity in different directions.

Abstract:

A photocopier tray cassette lift plate is lockable against the upward bias of its springs by a tab extending down to engage a lower latch member mounted to the tray base. The lower latch member is spring biased toward a position in which it may engage the tab, and is movable toward a disengaging position by a forwardly projecting surface that engages the photocopier frame upon insertion of the tray.

Abstract:

A metering roll, employed between the developing station and the transfer station of a photocopier which uses a liquid toner, controls the thickness of the liquid on the photosensitive drum surface when it is presented to the transfer station. Shoe-like elements fixed between the drum and roll maintain the central metering portion in a substantially constant spaced apart relationship to the photosensitive drum surface and thereby tend to limit and control the thickness of developer on the drum surface at the transfer station. One surface of the element substantially conforms to an arc of the drum surface and another surface defines a hole through which a portion of the metering roll passes.
