Abstract: A tray for holding a stack of sheets of paper for feeding into a printer includes opposite paper guides one of which is adjustable relative to the other for varying the spacing between the paper guides. The adjustable paper guide is slideable across the tray and includes a releasable lock which engages the tray for locking the paper guide in position. The releasable lock is preferably a spring biased lever which includes a tooth that normally engages a rack in the paper tray until released by operation of the lever for the paper guide to be adjusted. As the paper guide is locked in position it cannot move away from its location during feeding of papers from the tray. The paper guide may also include a spring arm for applying a bias against the edge of the sheets of paper as they are fed from the tray to prevent them from skewing.

Abstract: A mounting system is disclosed for removably mounting rollers and cylinders in a machine for quick and easy removal and replacement by other rollers and cylinders. The mounting system provides for rapid separation of the journal from the roller or cylinder so that only the roller or cylinder is removed, and the mounting system has particular applicability with respect to ink rolls in printing machines.

Abstract: A suction transport device capable of reducing manufacturing cost due to reduction of the number of suction mechanisms by which one of photopolymer plates accommodated in a magazine is taken out is attained. Also separability when the printing plate is taken out is improved, thus improving reliability of the suction transport device. Since, among suckers and suction fans, those located at positions corresponding to the widthwise direction ends of the printing plates are movable in the widthwise direction, and separating plates are movable in the same direction. When one of the printing plates of a different size is to be taken out, the leading end corner portions of the printing plate can always be curved at a fixed curvature, and separability is improved. Further, there is no need to increase the number of suckers thus decreasing cost.

The printer includes a print head and platen opposing to each other for printing the recording medium. A first printer housing houses the platen, and a second printer housing movably connected to the first housing houses the print head. The printer also includes an ejection port, defined at the border of the first and second printer housings, from which the recording medium is ejected after printed by the print head and platen, and a separator for curving the base sheet ejected from the ejection port to separate the leading edge of the label sheet from the base sheet.

Abstract: An apparatus and method for drying a receiver media (30) in an ink jet printer. The apparatus generally comprises a means for creating a pressure differential between the upper surface (20) and the lower surface (50) of the receiver media (30), wherein the pressure at the lower surface (50) of the receiver media (30) is lower than the pressure at the upper surface (20) of the receiver media (30). The pressure differential-creating means may include a vacuum pump (70) adapted to generate a vacuum at the lower surface (50) of the receiver media (30) or an air pump (130) adapted to pass air currents (140) across the lower surface (50) of the receiver media (30) to cause a “Bernoulli effect”.

Abstract: A printing press has a support arm that can move between lower and upper positions, first and second link plates swingably supported by a main frame and the support arm, respectively. A connection pin having a protruding end portion is provided to connect the link plates. A support lever, swingably supported by the main frame, has an engagement groove which disengageably engages with the protruding end portion of the connection pin. When the support arm moves from the lower position to the upper position, the protruding end portion of the connection pin comes into contact with the edge surface of a lower portion of the support lever, and swings the support lever. When the protruding end portion of the connection pin reaches the engagement groove of the support lever, the protruding end portion engages with the engagement groove, so that the support arm is held at the upper position.

Abstract: This invention relates to a media weight sensor of the type that includes a transducer consisting of a metal desk with a piezoelectric element fabricated by one side which form the back of a Helmholtz resonator cavity mounted in a printer so that the media going to the printer moves across the top of the Helmholtz resonator where an opening of the resonator is located. A soft, polymeric roller is used to press for media and is the transducer. The resonant frequency of the Helmholtz is affected by the media. The mass of the media adds to the mass of the resonator, thereby lowering the resonant frequency. Consequently, the heavier than media, the more the resonant frequency is lowered.
