  • Publication number: 20120248692
    Abstract: A sheet cassette includes a lock lever that engages a lock projection in an engagement portion of an stacking plate located in a lower position to enable the stacking plate to turn in a locked position in which the stacking plate is locked in a cassette body and an unlocked position in which the lock projection is separated from the engagement portion in lifting the stacking plate. In a state in which the sheet cassette is mounted on the apparatus body, the lifting and lowering device turns the lock lever to the unlocked position in lifting the stacking plate locked in the lower position by the lock lever. Accordingly, by a simple configuration in which an existing configuration can be used, a lock structure can be made so as to be reused in movement of the apparatus such as a move.

  • Patent number: 8262083
    Abstract: A media cassette includes a body having a removable lid. The media cassette comprises a housing defining a closeable pick window; an urging plate biased towards the pick window for urging a stack of media items towards the pick window; a detent located distal from the pick window for limiting movement of the urging plate; and a detent moving mechanism operable to move the detent. The detent moving mechanism may be operated by engaging the removable lid or by insertion of the cassette into a media handler. The media cassette allows the urging plate to exert less force on the stack of media items by expanding the space available for media items located within the cassette by activating the detent moving mechanism.

  • Publication number: 20120205861
    Abstract: When a sheet cassette (10a) is pulled out of the body of an image forming apparatus (100), winding pulleys (40a and 40b) are rotated by the weight of a lift plate. An idle gear (47) also is rotated by a predetermined amount, so that the engagement portion (47b) thereof engages with a second arm portion (50c) of a torsion spring (50). Since a force exerted by the torsion spring (50) is set greater than the force that rotates the idle gear (47) by downward movement of lift plate (30), rotation of the idle gear (47) and winding pulley (40a) is regulated, and thus the upper surface of lift plate (30) stops in a substantially constant position with respect to sheet supply opening portions (31a and 31b).

    Abstract: A sheet feeder has a tray on which a sheet to be fed is to be placed. A lift plate is at a feeding end of the tray and has a first end at an upstream side in a feeding direction connected rotatably to the tray. The lift plate is displaceable between a feeding posture where a second end at a downstream side in the feeding direction is lifted up and a retracted posture where the second end is lower than in the feeding posture due to its own weight. A biasing member gives a biasing force to an elevating member in a direction to lift the lift plate to the feeding posture. A lowering mechanism gives a pressing force against the force of the biasing member to lower the lift plate to the retracted posture.

  • Patent number: 7686293
    Abstract: A print media feeder apparatus suitable for use in an image-forming device is provided. The apparatus comprises an elevator tray holding a stack of print media connected to a housing by a transmission system. The housing comprises a hoist drum that is connected to one end of a shaft for connecting the housing to the transmission system. A spring enclosure encasing a spring is fixed on the other end of the shaft. The load of print media is transmitted to the hoist drum, from which it is further transmitted to the spring through the shaft. This results in the displacement of the spring and a corresponding vertical movement of the elevator tray to position the print media at the desired feeding level.

  • Patent number: 7677523
    Abstract: A gravity compensation device partially or completely compensates a force exerted by a basic mass (10) on a balancing device (12) at a first distance from an axis of rotation (13) by using a force generating device, such as spring (14), exerting a counterforce on the balancing device at a second distance from the axis of rotation. The first distance, the second distance, or both are selectable for providing the desired gravity compensation. One or more pulleys with an angle-variable radius may be used. The gravity compensation device does not add substantial mass to the basic mass, and is simple in design.

  • Patent number: RE42269
    Abstract: A double side scanner module which consists of a U-shaped inversion device and two image information reading devices is provided for reading images on the two sides of an original in a single pass. The U-shaped inversion device has two ends for providing a paper feeding path and a paper output path respectively. The two ends are at the same side for the convenience of operation. At both of the two ends, there is a glass window. Beneath each of the glass windows, there is an image information reading device. When an original is fed into the paper feeding end and conveyed through the first glass window, the first image information reading device starts to read the image on the first side of the original. When the original is conveyed through the U-shaped inversion device, the scanned side will be inverted to the other side.
