Abstract: A sheet repository having multiple trays and including a fan supported in a housing for receiving ambient air from outside the housing, a heating device within the housing for raising the temperature of the air conveyed by the fan, and a duct system at the outlet of the heating device for channeling the heated air. The duct system includes outlets for directing heated air onto the selected trays, and a humidity sensor provides suitable signals to shut off the heating device in order that the sheets in the trays are maintained at a uniform reduced moisture content.

Abstract: A fluorescent light source includes a fluorescent lamp, lamp bases attached to opposite ends of the fluorescent lamp, and an electrically insulating substrate connected to the fluorescent lamp. A heating element is positioned on the fluorescent lamp, and a first and second pair of power traces are formed on the electrically insulating substrate. The first pair of power traces are connected to the heating element to provide power thereto. The second pair of power traces are connected to a pair of electrical conductors that provide power to the fluorescent lamp. This fluorescent lamp can be used in a replaceable fluorescent light source unit for a document scanner. The replaceable fluorescent light source unit includes a housing, lamp base receiving members attached to the housing, and registration notches to properly align the fluorescent lamp.

Abstract: The present invention is concerned with a pivotable connector latch for securing together a pair of mating electrical connector members. The latch includes a pivot end secured to one end of one of the electrical connector members and a clamp end having a U-shaped member including one leg with a resilient spring for snapping the latch onto another end of the connector member. An elongated locking section of the latch, with an elongated lip between the pivot end and the clamp end fixedly secures the connector members together. The other leg of the U-shaped member is a straight clip section with a beveled edge for engaging one of the connector members.

Abstract: A control knob for permitting the service technician to adjust the operating level of a component in an electrostatic type reproduction machine with locking means effective to prevent unauthorized adjustments by others. To enable the machine user or operator, when training and experience warrants it, to perform service adjustments, the control knob incorporates an internal release mechanism, settable only by the machine service technician, permitting selected adjustment by the operator despite the locking means.
