Abstract: A paper sheet feeding apparatus is constructed of paper feed rollers arranged in association with a respective paper tray and adapted to be driven by rotation of a printer platen in a forward paper feeding direction, with selection of the appropriate paper tray from which paper is to be fed, by a combination of forward and reverse rotations of the printer platen. The paper feed rollers, associated with each of the paper trays, are mounted on shafts which extend transversely of the apparatus. A plurality of driven gear assemblies are respectively arranged in operative association with the paper feed rolls and are adapted for lateral sliding movement between engaged and disengaged positions relative to a selector gear whose rotation is synchronized with that of the printer platen.

Abstract: A paper tray for a printing device is disclosed having a pair of paper supporting members, movable relative to one another, for supporting the lateral sides of a stack of individual sheets of paper. The movability of the paper supporting members relative to one another allows the paper tray to accommodate stacks of individual sheets of paper having different widths or size. The paper supporting members are provided with a concave paper supporting surface such that the stack of individual sheets of paper assumes a concave shape, thereby having sufficient mechanical strength to be self-supporting in the unsupported region between the paper supporting members. The curved shape of the stack is provided, in part, by a forwardly arranged paper pressing plate which is rotatable about an axis spaced from the rotational axis of a control rod which is adapted for rotating the paper pressing plate into a position for replenishing the individual sheets of paper within the stack.

Abstract: There is illustrated and described a printing device having an integrated paper feeding apparatus adapted for supplying individual sheets of paper to the printing device to effect printing thereon. The integrated printer and paper feeding apparatus for the present invention is particularly suitable for use in word processing systems where the information to be printed in hard copy is contained in a memory device such as a floppy disk or the like. The apparatus may be directly linked to word processing equipment to receive the text of material to be printed. In addition to having the capability of automatically feeding individual sheets of paper from one or more paper trays to the printing device, the apparatus includes an automatic envelope supply mechanism for supplying individual envelopes to the printing device, as well as a manual paper feed option. After effecting printing on the paper or envelope, an ejector mechanism ejects the printed paper from the apparatus and into a receptacle in collated form.

Abstract: A locking assembly is disclosed for mounting a print wheel of the daisy type to a rotary drive mechanism. The locking assembly is constructed of a print wheel stop rotatable with the shaft of the drive mechanism, a print wheel retainer slidable along the shaft between a print wheel connecting and attaching position and biasing means for biasing the print wheel retainer into the connecting and attaching positions. The print wheel is provided with attaching members for engaging a portion of the print wheel retainer while being supported by the print wheel stop for detachably connecting the print wheel thereto and for permitting detachment of the print wheel therefrom when the print wheel retainer is arranged by the biasing means into the detaching position. Further in accordance with the present invention there is provided a carriage assembly adapted for tilting the print wheel to facilitate replacement and/or removal thereof wherein the carriage assembly is provided with a bias plate.

Abstract: A paper feeding apparatus capable of feeding both individual sheets of paper, such as stationary, and envelopes to a printing device for printing of matter thereon, the printing device including a print head for printing on a sheet of paper and a paper moving platen for providing relative movement between the sheets of paper and the print head to effect printing on the paper. The paper feeding apparatus includes a first paper storage tray for storing a plurality of sheets of paper, and first paper drive rollers for feeding of a sheet of paper from the paper storage tray along a paper feed path to the platen on the printing device. The paper feed path is at least partially defined by a deflector plate which is arranged opposite from the first paper storage tray and is parallel to one side of the paper feed path so that sheets of paper are deflected by one surface of the deflector plate to be directed toward the paper moving platen as they are fed from the paper storage tray.

The paper feeding apparatus includes a paper storage tray for storing a plurality of sheets of paper, and a paper drive and guide apparatus for feeding a sheet of paper from the paper storage tray along a paper feed path to the platen of the printing device. A sensor is provided in the paper feed path for sensing when a sheet of paper is in position for being received by the platen, at which time the platen is then actuated to receive the sheet of paper being fed along the paper feed path and to move the sheet of paper relative to the print head to accurately position the sheet of paper in a printing position for the start of printing thereon by the print head.
