Abstract
A carriage drive control device is provided which moves a carriage at a constant speed in a recording area for recording operation and which moves the carriage to a target stop position in a better way for non-recording operation. A controlled variable of actuator is calculated based on a speed error between a target speed and a moving speed of the carriage. The target speed is set based on a position error between the target stop position and a current position of the carriage, and is not more than a predetermined first speed. When the actuator starts moving the carriage for recording operation, a control rule used for calculation of the controlled is set to a first control rule, and when the actuator starts moving the carriage for non-recording operation, the control rule is set to a second control rule.
