摘要： Provided are a recording apparatus and a motion unit drive method that determines a stop rotation torque of a CR motor indicating stop of a carriage by a stopper and, within a predetermined period after the determination of the stop rotational torque, supplies to the CR motor the drive signal that causes a rotational torque of the drive motor to be a low rotational torque having a smaller torque value than the stop rotational torque.

摘要： When printing is performed by discharging ink from a printing head onto a lenticular, a carriage motor is controlled such that a carriage is moved in a main scanning direction at a velocity which is slower than a movement velocity of the carriage at the time of performing a normal printing process with respect to a recording medium different from the lenticular as a recording paper and further separated from a home position, and the printing head is controlled such that an ink discharge having a color according to printing data is started with respect to an end portion of the lenticular, and thus the printing of one pass is started. Since the velocity is slower than the movement velocity of the carriage at the time of performing the normal printing process, it is possible to improve printing quality at the time of performing printing with respect to the lenticular.
摘要翻译：当通过将油墨从打印头排出到双凸透镜来执行打印时，滑架电机被控制成使得滑架在主扫描方向上以比在滑架的执行时的滑架的移动速度慢的速度移动相对于作为记录纸不同于透镜的记录介质的正常打印处理，并且与原始位置进一步分离，并且控制打印头，使得根据打印数据的颜色相对于端部开始具有颜色的排墨透镜的一部分，从而开始一次打印。由于速度比执行正常打印处理时的滑架的移动速度慢，所以可以提高打印时相对于透镜的打印质量。

摘要： For a lenticular in which a lens body having low shape accuracy is disposed on one end portion, when the other end portion of the lenticular is detected, a position of a carriage at the time of detecting the end portion of the lenticular is stored in a buffer as a paper end position, a carriage motor is controlled such that the carriage is separated from a home position and moved in a main scanning direction, and a printing head is controlled such that an ink discharge having a color according to printing data is started at the paper end position. Since the lens body having high shape accuracy is disposed on the end portion of the lenticular, it is possible to land the ink onto a more suitable position with respect to the lens body, thereby allowing printing quality to be improved.
摘要翻译：对于在一个端部设置具有低形状精度的透镜体的透镜状体，当检测到透镜的另一端部时，检测透镜的端部时的托架的位置被存储在缓冲器作为纸张结束位置，滑架电机被控制成使得滑架与原始位置分离并沿主扫描方向移动，并且控制打印头使得根据打印数据具有颜色的喷墨开始在纸张结束位置。由于具有高形状精度的透镜体设置在透镜的端部上，所以可以将墨水对准相对于透镜体的更合适的位置，从而可以提高打印质量。

摘要： A medium feeding device includes a feeding roller that is provided in a medium feeding path through which a medium is fed and that feeds a medium downstream by rotating in the forward direction in response to power of a motor, a nip roller that is provided in the medium feeding path and that nips a medium in cooperation with the feeding roller and rotates, and a controller configured to control the motor. Based on an increase in a variation value varying in accordance with a drive load of the motor, the controller controls the motor and causes the feeding roller to start a medium feeding operation.

摘要： A medium transport device includes a feeding roller that feeds a recording medium, a transport roller that transports the recording medium toward a recording head, and a transport motor which is a common driving source for the feeding roller and the transport roller. The medium transport device includes a power transmission mechanism that transmits power of the transport motor to the feeding roller, and a control section that controls a current of the transport motor. The control section measures a current value flowing through the transport motor during driving as a measured current value, and adds a predetermined offset value to the measured current value to set a second limit value as a limit value of the current supplied to the transport motor.
