Abstract: In an image recording apparatus, a peak load that is the highest load applied to a carriage moving in a first direction in a first load region is highest at a first highest-load position. A second load is highest at a second highest-load position of a second load region. In a retry processing, when a stop position of the carriage which is detected by a detector is located between the first highest-load position and the second highest-load position, the controller moves the carriage in the first direction toward a target position after moving the carriage from the stop position in a second direction to a first retry position located downstream of a restoration position in the first direction.

Abstract: A movement unit moves a reading unit in a first direction and a second direction. A control unit controls the movement unit so that the reading unit is positioned in a predetermined region in a case when a transition is made from an operation mode to a non-operation mode and controls the movement unit to cause the reading unit to move from the predetermined region to a position at which a white reference plate can be read in a case when a transition is made from the non-operation mode to the operation mode. The control unit causes movement of the reading unit by the movement unit to stop when a movement amount of the reading unit measured by a measurement unit becomes a movement amount corresponding to a distance from the boundary to a position at which a white reference plate can be read.

Abstract: The optical scanning apparatus correctly measures a gap between the laser beams of a plurality of the laser beams even when the scanning speed is changed and when the variation is caused, rightly corrects the variation. Thus, the optical scanning apparatus inputs detection signal BD_IN to the edge detecting unit at timing at which the laser beam is detected. During the enable gating, the count value representing the distance between the head laser beam and the end laser beam is counted in the counting unit. A plurality of speed ratio parameters according to the degree of changes in the scanning speed is input in the selector. The selector selects any one of the speed ratio parameters and multiplies by the count value by the multiplier, it is controlled to obtain the same multiplication result whichever scanning speed may be selected.

Abstract: An image reading device includes first carriage, a stepper motor, a shakiness level calculating section, and a timing adjusting section. The first carriage reads an image of a document to be read loaded on a document table. The stepper motor moves the first carriage relative to the document. The shakiness level calculating section calculates a shakiness level of the image, indicating shakiness of the image during reading by the first carriage, based on image data read by the first carriage with respect to a reference image incorporated into the document table. The timing adjusting section adjusts a rise timing of a step signal input to the stepper motor in accordance with the shakiness level that is calculated.
