摘要:
A paper handling apparatus 10 for an electrophotographic printer and, in particular, a desktop laser printer includes a series of paper containing trays 12, 14, 16, 18, which are configured to receive a variety of different styles and sizes of sheets of paper. The trays 12, 14, 16, 18 are individually horizontally arranged and collectively configured in a vertically stacked arrangement. A single paper feeding mechanism 20 is configured for selective operation with each of the vertically stacked trays 12, 14, 16, 18 by employing a rolamite to provide controlled vertical movement of the paper feeding mechanism 20 adjacent the vertically stacked trays 12, 14, 16, 18. The trays 12, 14, 16, 18 are selectively horizontally moveable so as to intersect the vertical path of the paper feeding mechanism, so as to allow the single paper feeding mechanism 20 to selectively engage one of the plurality of trays 12, 14, 16, 18 and sequentially remove individual sheets of paper from the selected tray 12, 14, 16, 18.

A paper handling apparatus 10 includes a plurality of paper receiving trays 12, 14, 16, 18 arranged vertically in close proximity to one another with a single paper feeding mechanism 20 provided to operate with all of the trays 12, 14, 16, 18. The paper feeding mechanism 20 moves vertically to selectively engage any selected one of the plurality of trays 12, 14, 16, 18. The vertical arrangement of the trays 12, 14, 16, 18 dictates that the trays are horizontally moveable between a first unselected position, where the trays are substantially vertically aligned with the one another, and a second selected position where the tray is horizontally moved to intersect the vertical path of the paper feeding mechanism 20. Horizontal movement of the trays 12, 14 16, 18 is effected by a single electric motor 28 rotatably attached to a shaft 30, which carries a series of gears 32, 34, 36, 38 that interact with a corresponding rack 40, 42, 44, 46 disposed on each of the trays 12, 14, 16, 18, respectively. A transmission 48 links the motor 28 to the gears 32, 34, 36, 38 to selectively drive one of the gears and move one of the trays between the selected and unselected positions.

A dual bin paper feed tray is removably insertable into the standard height tray-receiving housing opening of an image reproduction machine such as a printer or copier. The tray has adjacent front and rear paper holding bin areas each configured to hold a stack of approximately 250 cut paper sheets, the overall tray thus being adapted to hold the entire contents of a standard one ream package of cut paper sheets. In operation, the loaded tray is inserted, front end first, into the housing opening and the machine's paper feed system operates to sequentially feed paper sheets from the front tray bin into the machine. When the machine's paper sensing system detects that the front bin has been emptied, a shift structure incorporating a motor-driven gear train and associated cam/follower apparatus is automatically operated to move the rear paper stack into the front tray bin for infeed to the machine.

摘要:
Paper handling mechanisms for printers, copiers and the like typically have a separate paper feeding mechanism associated with each paper tray. The separate paper feeding mechanisms can only remove paper from the associated tray. Therefore, the paper handling mechanisms are redundant, space consuming, and inefficient to use. Disclosed herein is a paper handling mechanism that uses a single paper-feeding mechanism to remove paper from a plurality of trays. Since a separate paper-feeding mechanism is not required for each tray, more trays may be disposed in the same vertical space of prior printers or copiers. Advantageously, the single paper-feeding mechanism moves generally vertically, and the trays selectively move generally horizontally to intersect the paper-feeding mechanism. Preferably, a plurality of gears are disposed adjacent each horizontally moveable tray. The plurality of gears are adapted to engage a corresponding gear member on each of the respective trays. To move a selected tray horizontally to intersect the paper-feeding mechanism, one of the plurality of gears moves into engagement with the corresponding gear member on the selected tray, and imparts horizontal motion to the selected tray so that the paper-feeding mechanism can remove paper from the selected tray.

摘要:
The housing of a portable computer docking station has an exterior wall with an opening formed therein through which a PC card may be inwardly passed for operative insertion into a PC card ejection mechanism disposed within the housing in a facing, inwardly spaced relationship with the exterior wall opening. A molded plastic access door member has a pair of outwardly projecting pin portions which are releasably snap fitted into socket structures formed on interior housing mounting walls to thereby support the door for pivotal movement between closed and open positions in which the door respectively blocks and unblocks the exterior wall opening. Complementarily sloped surfaces on the pins and the sockets are engageable in a manner resiliently deforming the door as it approaches either of its closed and open positions and then permitting the door to return to its original shape. As it returns to its original shape the door automatically drives itself through a final distance to its closed or open position as the case may be. The engageable sloped surfaces on the pins and socket structures, together with interengageable detent structures on the pins and sockets, function to releasably hold the door in its closed or open position. In this manner the door itself is used as an opening and closing spring, thereby eliminating the need for a separate spring member.

A universal acoustic coupler system includes a pair of flexible muffs for acoustically coupling a telephone handset to transducers (speaker/microphone) of an electronic input/output device. The muffs are formed of an external housing inside which an internal housing is positioned, defining a fluid insulator therebetween. The internal housing has a speaker/microphone cavity for receiving the input/output device speaker or microphone which opens into an earpiece/mouthpiece cavity for receiving the earpiece or mouthpiece of a telephone handset. The fluid insulator is formed to completely insulate the speaker or microphone to eliminate all external noise.
