Publication number: 20170320700Abstract: A removable media handling module includes a body that is horizontally slidable into and removable from an imaging apparatus. The media handling module includes a lower media guide extending between a front and a rear of the body. With the media handling module inserted into the imaging apparatus, the lower media guide is positioned parallel to and spaced from a corresponding upper media guide mounted in the imaging apparatus to form at least a portion of a duplex media path therebetween. A drive mechanism including a clutched gear is operably connected to a feed roll assembly of the media handling module. The clutched gear is freely rotatable in a first direction that causes the feed roll assembly to rotate in a media process direction for feeding a printed media sheet along the duplex media path and is restrained from rotating in a second direction opposite the first direction.Type: ApplicationFiled: May 4, 2016Publication date: November 9, 2017Inventors: DONALD E.

Patent number: 7673369Abstract: A floor cleaning apparatus includes a dirt collection vessel and a suction generator carried on the housing. The dirt collection vessel includes a dirty air inlet, a dirt collection chamber and a clean air outlet. A filter is received in the dirt collection vessel. The filter includes multiple sections. Each section provides a discrete airflow pathway. In addition, the floor cleaning apparatus includes a flow control valve assembly including a clean air inlet. The flow control valve assembly is selectively displaceable between two positions. In the first position dirty air is serially moved by the suction generator through the dirty air inlet, the dirt collection chamber, the filter and the clean air outlet so that dirt is collected in the dirt collection chamber. In the second position clean air is moved by the suction generator through the clean air inlet, a selected one of the sections of the filter, back through the other sections of the filter and then through the clean air outlet.Type: GrantFiled: July 22, 2005Date of Patent: March 9, 2010Assignee: Panasonic Corporation of North AmericaInventors: Nathan A. Gogel, Yasushi Kondo, Donald E. Proffitt

Patent number: 7555810Abstract: A floor care apparatus includes a housing having a nozzle assembly and a canister assembly. A suction inlet is provided on the nozzle assembly. A dirt collection vessel, a suction generator and a wand receiver are carried on the housing. A first air flow pathway connects the suction inlet to the dirt collection vessel and the suction generator. An air flow control valve includes a valve body received in the first air flow pathway and an actuator having at least a portion thereof extending into the wand receiver. A cleaning wand assembly is displaceable between a first storage position wherein a first end of the cleaning wand assembly is held in the wand receiver engaging the actuator and opening the valve and a second position wherein the cleaning wand assembly is withdrawn from the wand receiver for cleaning with the cleaning wand assembly thereby disengaging the actuator and closing the valve.Type: GrantFiled: March 8, 2007Date of Patent: July 7, 2009Assignee: Panasonic Corporation of North AmericaInventors: Alan T. Pullins, Shannon D. Phegley, Donald E. Proffitt, II, Eric J. Streciwilk
