  • Patent number: 10906761
    Abstract: A method and apparatus for processing documents are provided. The apparatus includes a feeder for receiving a packet of a plurality of documents and separating the documents to serially feed the documents to a scanner. A retard adjacent the feeder is operable in first and second positions. In the first position the retard forms a nip with the feeder so that the retard is operable to impede the progress of one or more documents in the packet while the feeder feeds one of the documents in the packet. In the second position, the retard is spaced apart from the feeder to form a gap between the feeder and the retard. The system further includes a sensor for detecting a characteristic of the documents in a packet indicative of whether the number of documents in the packet exceeds a predetermined threshold. A drive mechanism automatically drives the retard pad between the first and second positions in response to the detected characteristic.

  • Patent number: 10705462
    Abstract: A motor driving unit controls motor conducted current of a brushed DC motor on the basis of a motor control signal. A motor control unit provides the motor control signal to the motor driving unit and thereby controls the brushed DC motor. A brush noise detecting unit detects brush noises in conducted current of the brushed DC motor and outputs a brush noise detection signal. A speed determining unit determines a time interval of the brush noises and determines a rotation speed of the brushed DC motor on the basis of the time interval. Further, the motor control unit determines whether the brushed DC motor is in a lock status or not on the basis of the rotation speed in a period that the motor control signal is provided to the motor driving unit to cause the brushed DC motor to be in operation.

  • Patent number: 10118778
    Abstract: A driven gear is relatively movable to a first support position and to a second support position on a support member. When a first gear rotates in a first direction, the driven gear rotates at the first support position in conjunction with rotation of the first gear to permit the rotation of the driven gear. When the first gear rotates in a second direction opposite to the first direction, the driven gear moves to the second support position under a force received from the gear in an area where the driven gear meshes with the first gear. Then, at the second support position, the driven gear is locked on a locking member and thus stopped, preventing the first gear from rotating in the second direction.

    Abstract: One aspect of the present invention provides an image forming apparatus that can prevent degradation of sheet feeding performance at low cost. A drive transmission portion 200B is provided between a driving motor 227 that drives a conveying roller 250 provided in an apparatus body and a body-side lifting portion 200C that drives a lifter mechanism 200A of a sheet feeding cassette 201 mounted on the apparatus body. When the sheet feeding cassette 201 is mounted on the apparatus body, the drive transmission portion 200B selectively transmits drive of the driving motor 227 to the lifter mechanism 200A through the body-side lifting portion 200C to lift a stacking plate 206 by a predetermined amount.
