A mounting apparatus and method is suitable for printed wiring assembly (PWA) shielding in an electrical device such as a facsimile machine. The mounting comprises a frame including a substantially flat frame floor, at least one PWA edge card connector, and at least one frame fastener. Continuous shielding walls are positioned immediately adjacent to the frame floor, and the PWA comprises a substantially flat component-mounting surface and a shielding surface, at least one PWA edge card, and at least one frame fastener receiver. The PWA edge card is inserted into the PWA edge card connector and the frame fastener is coupled to the frame fastener receiver such that the PWA component-mounting surface is held within an electromagnetically-shielded volume bounded by the PWA shielding surface, the shielding walls, and the frame floor.

Mounting method and apparatus for PWA shielding

A method and apparatus for the holding of paper rolls in printing devices, e.g., facsimile machines, which includes a housing for accommodating the paper roll, the housing comprising parallel and substantially flat first and second housing endplates along a longitudinal axis; first and second paper roll supports adapted to fit first and second ends of the paper roll, respectively, the first and second paper roll supports flexibly coupled to the first and second housing endplates; and first and second springs for pressing the first and second paper roll supports against the first and second ends of the paper roll, respectively, to compressively hold the paper roll when the paper roll is inserted in the holder, the first spring coupled between the first housing endplate and the first paper roll support, and the second spring coupled between the second housing endplate and the second paper roll support.
