ABSTRACT:
In an image recording apparatus, if a main sheet feed roller is displaced during rotation thereof, a carrier contacted with an outer peripheral surface of the main sheet feed roller via a pressure plate is rotated around a guide shaft upwardly or downwardly. As a result, a position of a nozzle of a recording head held by the carrier is changed. Further, a platen is rotated around support shafts upwardly or downwardly in response to rotation of the carrier around the guide shaft. As a result, a position of a recording surface of the platen is changed. In this way, even if the main sheet feed roller is displaced during rotation thereof, a distance between the nozzle surface of the recording head and a recording medium on the recording surface of the platen is always kept constant.
