An improved system and method for the selection and dispensing of reagents onto a target testing medium in an automated laboratory environment. The system utilizes multiple carousels rotatably-mounted upon a central turntable. The position of the central turntable, as well as the rotation of each carousel is controlled by a microprocessor-based control system. Multiple dispensers, each capable of storing and dispensing a particular reagent, are mounted about the circumference of each carousel. This configuration provides much higher reagent density than previously available. The testing medium is positioned at one or more loading stations. The control system directs the central turntable to a position from which a selected one of the carousels can be rotated so as to position a selected dispenser above the testing medium. The selected dispenser is then actuated to release a predetermined reagent onto the testing medium. The system can be configured so that multiple reagents can be dispensed, each from an associated dispenser, onto a single or multiple testing mediums. Each of these actuated dispensers being positioned over the targeted testing medium(s) positioned at one or more loading stations.

A detachable document handler (having an outer casing) has a transparent platen as the casing bottom, and a document tray as the casing top. A moveable internal scanner is located within the outer casing, and is positioned to move past the transparent platen within the outer casing. The moveable internal scanner is in a location within the outer casing to optically scan items external to the outer casing through the transparent platen. A sheet feeder system are also within the outer casing. The sheet feeder system (within the outer casing) is positioned adjacent the document tray in a location to feed sheets from the document tray, internally within the outer casing, past the moveable internal scanner, and back to the document tray. A transparent member within the outer casing is located between the sheet feeder system and the moveable internal scanner.

Devices have a movable roller, a fixed-position roller contacting the movable roller to form an exit nip transporting planar media, biasing members operatively connected to the movable roller, and adjusters contacting the movable roller. Such devices are connectable to a first machine or a second machine. Contact areas of the first machine hold the adjusters in a first position to position the movable roller in a position resulting in the exit nip transporting the planar media in a first exit direction. The second machine instead has void areas positioned to allow movement of the adjusters to position the movable roller in a position resulting in the exit nip transporting the planar media in a second exit direction different from the first exit direction.

An integrated document handling and platen scanning apparatus is provided. The apparatus includes a main body; a platen glass positionally fixed to the main body; a CVT glass area positionally fixed to the main body; a first image module attached to the main body, the first image module being movable across the platen glass to scan an image on a first side of a document; a document handler attached to the main body and configured to invert the document and to feed the document across the CVT glass area; and an attachment point on the main body that attaches the main body to a copier body of a photocopier such that the main body, platen glass, first image module, and document handler move as a unit relative to the copier body. The first image module is configured to remain stationary and scan the image on the first side of the document as the document is fed across the CVT glass area.

A registration gate is mounted in a sheet feeding mechanism for rotation about an axis at about right angles to the direction of sheet feed into a feeder mechanism. The gate includes a plurality of fingers extending upwardly through slots in the tray. A motorized sequencing cam moves followers to rotate the gate to an open position to retract the fingers below the tray, to raise and lower a nudger in and to move a lever for locking and unlocking the gate into the closed position with the fingers upright for registering the leading edge of the sheets during user loading of the tray. The cam may be detented or locked by a pawl engaging a notch in the cam.

A sheet from the top of a stack of media, and is driven by a reversible electric motor operated in a forward direction to drive a feed roll and nudger roll; and operated in a reverse direction to drive a cam profiled to raise and lower the nudger roll. One-way clutched gears may be provided to restrict rotation of the feed roll and the nudger roll when the motor is operated in a reverse direction; and to restrict rotation of the cam when the motor is operated in a forward direction. A rotary cam may be profiled to allow for the reciprocating movement of the nudger roll from a down position in which the nudger roll contacts the top of the stack of media to an up position in which the distance between the nudger roll and the top of the stack of media is suitable for loading media onto the stack of media.
