  • Patent number: 9369598
    Abstract: A reading apparatus includes an auto document feeder configured to be openable and closable around a hinge with respect to a unit including an image sensor. The auto document feeder includes a roller configured to move a document relative to the image sensor, a motor, a gear train configured to transmit a rotation of a rotational shaft of the motor to the roller, and an encoder unit configured to detect rotation information of the motor, and including a sensor and a code wheel. An orientation of the rotational shaft is substantially parallel to a rotational axis of the hinge, and the gear train is arrayed in a direction of an extension of the rotational shaft. A gear that is a part of the gear train is attached to one end of the rotational shaft, and the code wheel is attached to the other end thereof.

  • Patent number: 8964197
    Abstract: A reading apparatus includes an image sensor, a movement mechanism including a motor that relatively moves between a document and the image sensor, an encoder that detects information about the relative movement, and a control unit that controls driving of the motor and reading by the image sensor based on the detection by the encoder, wherein when a read-suspension event occurs during the reading, the control unit performs control such that the reading is continued while decelerating the motor, a relative position of a last read pixel with respect to a read position by the image sensor is monitored based on the detection by the encoder, and the driving of the motor is stopped when the read position is determined to reach a stop position set within the last read pixel, and the motor is driven again to resume the reading with a pixel next to the last read pixel.

  • Publication number: 20140322775
    Abstract: It is intended to provide a novel NAD+-independent myo-inositol 2-dehydrogenase which converts myo-inositol into scyllo-inosose in the absence of NAD+; a novel enzyme scyllo-inositol dehydrogenase which stereospecifically reduces scyllo-inosose into scyllo-inositol in the presence of NADH or NADPH; and a novel microorganism which belongs to the genus Acetobacter or Burkholderia and can convert myo-inositol into scyllo-inositol. By using these enzymes or the microorganism, scyllo-inositol is produced. Furthermore, scyllo-inositol is purified by adding boric acid and a metal salt to a liquid mixture containing scyllo-inositol and a neutral saccharide other than scyllo-inositol to form a scyllo-inositol/boric acid complex, separating the complex from the liquid mixture, dissolving the thus separated complex in an acid to give an acidic solution or an acidic suspension and then purifying scyllo-inositol from the acidic solution or the acidic suspension.

  • Patent number: 8366253
    Abstract: A printer includes a set cover pivotally movably provided on a carriage. The cover can be set in a closed state in which the cover presses a head of the cartridge housed in the housing portion and an open state in which the cover opens the housing portion when the cartridge is replaced. A release lever is subjected to a bias force so as to protrude from an inner wall surface of the housing portion. The release lever is movable against the bias force. The release lever comes into contact with an end of the cartridge which faces the bottom surface when the cartridge is inserted into the housing portion. The release lever contacts the rear surface of the cartridge housed in the housing portion. The bias force is stronger when the cover is in the open state than when the cover is in the closed state.
