Abstract: Multifunction reprographic apparatus comprises a housing having a first window in the front wall of the housing and a second window in the top wall of the housing. A mirror in the housing is pivoted to swing about a horizontal axis between an inclined position in which light from an illuminated original placed on the second window is directed through a lens system onto photosensitive paper positioned in the housing, and a horizontal position in which light from a subject placed in front of the first window is directed by the lens system onto the photosensitive paper. The apparatus is thus operable to make a photocopy of an original placed on the top window or to make a photograph of a person or other subject positioned in front of the front window.

Abstract: An ink liquid supply system for an ink jet system printer includes a constant flow rate pump and a pressure accumulator for removing a pressure pulsation or ripple created by the constant flow rate pump. In order to stabilize the constant flow rate operation and to shorten the preparation period of the system when the system operation is started, a temperature compensation or sensitive system is provided for varying the ink liquid pressure within the pressure accumulator. The temperature compensation system includes a bimetal element for varying the pressure to be applied to a resilient member included in the pressure accumulator. The pressure adjusting operation is continuously conducted even when the ink jet system printer does not operate.
