Abstract: An inkjet recording apparatus includes a conveying unit, a recording unit, a heat source, a heat source moving unit and a heat source moving control unit. The conveying unit performs a conveying operation to move a conveying member thereby conveying a recording medium placed on a conveying surface of the conveying member. The recording unit records an image by ejecting ink to the recording medium conveyed by the conveying unit. The heat source moving unit moves the heat source. The heat source moving control unit moves the heat source by the heat source moving unit such that a distance between the heat source and the conveying surface increases when the conveying operation which is performed by the conveying unit stops in a manner in which the conveying operation can be resumed in a state where the heat source is positioned in proximity of the conveying surface.

Abstract: A motor driving apparatus and a driving method thereof, and a mobile terminal in which a terminal voltage value of a terminal is detected at a terminal voltage detection unit, and is held in a holding circuit.
