  • Patent number: 10812001
    Abstract: A control device to control a motor includes a stator including a coil, a rotor including a permanent magnet, a detector that detects a rotational position of the rotor at every predetermined angle and outputs a position signal indicating the detected rotational position, and a controller that receives the position signal output by the detector and adjusts a duty ratio of a driving signal of the rotor by a pulse width modulation scheme based on the received position signal to control rotation of the rotor. The controller raises the duty ratio from a first duty ratio, starting from a point in time at which the position signal is received, and returns the raised duty ratio to the first duty ratio when a next position signal has been received.

  • Publication number: 20200329164
    Abstract: An image reading apparatus includes a transport unit, a reader, a detector, and a controller. The transport unit transports a document. The reader reads the transported document. The detector detects whether or not a document bundle prior to being transported is present. While a document in a first document bundle corresponding to a first job is being transported, if the detector detects that a document in a second document bundle corresponding to a second job as a subsequent job is loaded, the controller actuates the transport unit until all documents in the first document bundle are output.
