Abstract: A canopy includes a plurality of height-adjustable support frames including upper and lower frames; a bottom fixture inserted/fixed in each lower frame; a fixed two-point connection member fixed to each upper frame; a height-adjustable movable two-point connection member installed to each upper frame; three-point connection members positioned between the upper frames respectively; upper and lower four-point connection members positioned in the middle of the support frames respectively and having a vertically-installed anti-drooping frame; and pivoting frames whose both ends are connected to each connection member and whose center portion is hinged pivotally. Each pivoting frame has a insert group protruded on both ends of the pivoting frame at interval to prepare a vertical receiving groove. Each connection member has supports inserted into the insert groove, and an insert groove is formed in the supports to insert one of the inserts therein.

Abstract: An automatic document feeder for an image forming apparatus comprising a separation roller for separately carrying a plurality of paper sheets picked by a pickup roller, a feeding roller for carrying the paper sheets, a discharge roller for discharging the scanned paper sheets, and a transmission unit for transmitting a driving force from a driving motor. The transmission unit comprises an internal roller installed on the same axis as the feeding roller, the internal roller having an internal gear, a swing arm rotatably attached to a bracket, the bracket being inserted into the internal roller, and a swing gear rotatably installed on one side of the swing arm, the swing gear being engaged with the internal gear for rotating the internal roller.

Abstract: A paper feeding apparatus of an image forming device having a feeder opening and closing unit to automatically rotate a paper feeder between a storing position and a paper feeding-standby position selectively employing a driving source driving a transporting unit with a pickup roller and a feed roller. The paper feeding apparatus automatically opens the paper feeder to the paper feeding-standby position when the image forming device is used, and automatically closes the paper feeder to the storing position to minimize space when the image forming device is not in use, thereby accommodating a user and minimizing a size of the image forming device.

Abstract: Provided is a door-safety apparatus and a disc player including the door-safety apparatus. The door-safety apparatus includes a front panel including an opening, a door that is pivotally installed at the front panel to pivot between an opened position in which the opening is to be opened and a closed position in which the opening is to be closed, a rising and falling guide ascending and descending a pickup base on which a turntable placing a disc thereon is installed, and a door-forcibly-opening preventing unit installed between the door and the rising and falling guide and selectively limiting pivoting of the door according to a position of the rising and falling guide. In a door-safety apparatus and a disc player including the door-safety apparatus, when a disc tray is in a disc loading position, a door can be prevented from being forcibly opened.

Abstract: A paper feeding apparatus of a printer is provided. The paper feeding apparatus includes a plurality of paper guide ribs formed by protruding from one side of a rectangular hole of a base frame toward the other side of a rectangular hole and a plurality of rib receiving grooves formed on a feed roller positioned in the rectangular hole and corresponding to the paper guide ribs. With the paper guide ribs and the rib receiving grooves, the paper feeding apparatus prevents paper jam occurring when the upper end of a paper is caught in the rectangular hole and also prevents deterioration of print quality by uniformly maintaining the gap between a nozzle of an ink cartridge and a printable sheet of paper.

Abstract: An automatic sheet feeder of a printing machine feeds paper by a rotational pressing force exerted between a paper friction fed section and a paper feeding roller. The automatic sheet feeder includes an idle pad roller rotated in contact with the paper feeding roller by the rotational pressing force exerted on the paper feeding roller in absence of paper in the paper loading section, and an elastic member for elastically controlling the rotational movement of the idle pad roller in contact with the idle pad roller while the idle pad roller is rotated by the rotational pressing force of the paper feeding roller. Accordingly, even when the paper feeding operation is carried out in the absence of paper in the paper loading section, the frictional load between the paper feeding roller and the paper friction pad is minimized through the rolling friction operation of the idle pad roller.

Abstract: The present invention relates to an improved paper discharge apparatus of a printer having a star wheel over a paper discharge roller, separated from a paper discharge part in order to perform an amicable paper discharge function, thereby preventing the blur of ink on paper. The apparatus comprises a paper discharge roller for imparting the discharge force to a sheet of paper printed, a star wheel for imparting the force of press required for the paper discharge at the upper portion of the paper discharge roller, a spring line whose both ends are fixed at a base frame by a fixing means, the spring line supporting the star wheel and functioning as a shaft which is able to make the star wheel rotate, and a wheel frame having a wheel location guide, the wheel location guide being fixed at the base frame for supporting the spring line at its regular location, and preventing the location movement of the star wheel.

Abstract: A conveyance apparatus for an ink-jet printer for ejecting sheets of recording paper from the ink-jet printer regardless of whether the cover to the printer is closed or open. The ink-jet printing apparatus has a cartridge including a print head for forming an image on the recording paper. After passing the print head, the sheets of recording paper pass through the conveyance mechanism used to eject the sheets of recording paper. The ejecting occurs by pressing a spring loaded star-wheel against an eject roller. However, when the cover is opened, the star wheel becomes disengaged with the eject roller, causing the paper to jam instead of being ejected. To correct this problem, the star wheel engages a second eject roller when the cover is opened, allowing the paper to be ejected instead of jammed when the cover is opened.
