  • Patent number: 4941591
    Abstract: An office-type stationery set, which comprises a basic box seat to be placed on the desk, and an upright paper holder seat, to be covered with a cover made of transparent or enlarged-functional material, and connected with the rear wall of the basic box seat. The basic box seat includes a pen-stand seat, pen-stands, paper deposit box and paper dispensing device. The paper dispensing device is upright set on the lid of the paper deposit box comprising a button, a connecting rod, a pushing rod, and a pushing wheel. When the button is pressed, the driving rod will be oriented downwards and therefore push the connecting rod, to be responsive in movement to make the pushing rod which is pivoted on its front end, to move forward. The pushing wheel on the rear end of the pushing rod will not roll, as a ratchet is set to be an obstruction, but will rub on the paper and by frictional force push it out of the box.

  • Patent number: 4475733
    Abstract: An apparatus for feeding individual substrates from the top of a stack of substrates includes a paddle wheel having a hub with a plurality of blades attached thereto. The paddle wheel is positioned in driving relation to the substrate stack. As the paddle wheel is rotated, the blades come in contact with a spiral track which retards the motion of the blade tips through controlled bending and thereby stores potential energy in the blades. Continued rotation of the paddle wheel allows the blades to spring forward from the track just prior to or during substrate contact thereby changing the potential energy of the blades into kinetic energy. The sudden acceleration of the blades due to the change from potential to kinetic energy causes an increase in inertial separation of the top substrate in the stack from the remainder of the stack.

  • Patent number: 4475732
    Abstract: A retard feeder and separator apparatus adapted to sense the threat of a misfeed or multifeed and adjust the stack normal force of a feed belt against a stack of sheets accordingly. The apparatus includes a movable frame on which is mounted a sheet separating feed belt, a retard roll that forms a retard nip with the separating feed belt, and a stack force relief sensor. The sensor detects the lead edge of a sheet fed from a stack as it reaches the retard nip and causes a solenoid connected to the frame to trigger and move the frame slightly. The frame movement relieves the stack normal force of the feed belt against the stack from a high value to a low value while the sheet continues to be fed from the stack by the force in the retard nip and the lessened stack normal force. Alternatively, if the sensor does not sense a sheet within a predetermined period of time, the stack normal force will be increased to the original high value.

  • Patent number: 3964740
    Abstract: A sheet-feeding apparatus for separating and feeding sheets of paper, cardboard, metallic and plastic material and the like individually from a stack of such sheets is described. The apparatus as described is provided with a curved sheet-receiving chute for containing and temporarily storing a stack of sheets. A chamber having an apertured movable wall is provided adjacent the stack of sheets. The movable wall is positioned and freely movable to contact the top sheet of the stack. A low-pressure blower is provided for evacuating air from the chamber and drawing the top sheet into sealing contact with the movable wall about the aperture. Sealing of the aperture creates a partial differential pressure which moves the wall, reducing the volume of the chamber and removing the top sheet from the stack. Means, such as a roller, is also provided within the chamber. The roller extends slightly through the aperture to contact the sheet once the sheet is removed from the stack.
