  • 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.

  • Patent number: 8922801
    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: 8081352
    Abstract: An image reading/recording apparatus which can prevent a reading unit from closing abruptly and reduce the force required to open the reading unit is to be provided. The apparatus is equipped with a damper unit which links the apparatus body and the scanner unit and the working direction of whose force is reversed on the way of the turning of the scanner unit, and a metal-made supporting member which is arranged in the apparatus body and supports the damper unit in a state in which the scanner unit is closed relative to the apparatus body.

  • Patent number: 7561432
    Abstract: A memory card reader apparatus includes an electric board having a connector into which a memory card is inserted, a board holder holding the electric board, a card connector cover having a card slot, and an exterior cover different from the card connector cover. The board holder is positioned relative to the exterior cover. The board holder and the card connector cover are positioned in at least two directions perpendicular to the direction in which the memory card is inserted and pulled out.
