1. An image recording apparatus, comprising:
a supply roller configured to supply a sheet to a conveyance path; a conveying roller rotatable forwardly to convey the sheet supplied by the supply roller in a conveying direction and the conveying roller being rotatable reversely; an output roller rotatable forwardly to convey the sheet conveyed by the conveying roller in the conveying direction; a carriage provided with a recording head configured to perform image recording on the sheet, the carriage being disposed between the conveying roller and the output roller in the conveying direction and configured to be moved in a moving direction intersecting the conveying direction; a motor rotatable in a first rotational direction and in a second rotational direction reverse to the first rotational direction; a transmission mechanism configured to:
cause driving power generated by the motor during rotation thereof in the first rotational direction, to be transmitted not to the supply roller, transmitted to the conveying roller to rotate the conveying roller forwardly, and transmitted to the output roller to rotate the output roller forwardly; andcause driving power generated by the motor during rotation thereof in the second rotational direction, to be transmitted to the supply roller to rotate the supply roller, transmitted to the conveying roller to rotate the conveying roller reversely, and transmitted not to the output roller; and a controller configured to execute:
a supply processing in which the controller controls the motor to rotate in the second rotational direction to cause the supply roller to supply the sheet;a conveyance processing in which the controller controls the motor to rotate in the first rotational direction to cause at least one of the conveying roller and the output roller to convey the sheet in the conveying direction;a recording processing in which the controller controls the carriage to move in the moving direction and controls the recording head to perform the image recording during moving the carriage, while the conveyance processing is not being executed;controlling the carriage, the recording head, and the motor to perform an image recording operation by executing the conveyance processing and the recording processing alternately; anda pre-discharge supply processing as the supply processing in the image recording operation at a point in time in a period starting from a timing when a trailing edge position of a first sheet passes through the conveying roller and ending at a timing when all the recording processings on the first sheet are completed, the controller being configured to, in the pre-discharge supply processing, control the supply roller to supply a second sheet to the conveyance path, following the first sheet being stopped from being conveyed, in a state in which the trailing edge of the first sheet is positioned between the conveying roller and the output roller in the conveying direction, in the conveyance processing. |
