    • A rotary-member control apparatus includes a rotary member that rotates while supporting an object on the outer curved surface of the member. A motor is supplied with current based on a current profile representing the magnitude pattern of current to rotate the rotary member. A detecting element detects a rotation state of the rotary member during rotation. A control unit generates a one-rotation current profile, representing the magnitude pattern of current corrected on the basis of the detected rotation state, corresponding to one rotation of the rotary member, and supplies corrected current to rotate the rotary member. When the length of the medium in the rotation direction, the length of the medium in the axial direction, or the type of the medium is changed, the control unit generates the one-rotation current profile before starting printing, and repeatedly supplies the corrected current to the motor to print the image.
    • 旋转构件控制装置包括旋转构件,该旋转构件在构件的外部弯曲表面上支撑物体的同时旋转。 基于表示电流的幅度图案的电流曲线来向电动机提供电流以旋转旋转构件。 检测元件在旋转期间检测旋转构件的旋转状态。 控制单元产生一个旋转电流曲线,其表示对应于旋转构件的一次旋转的基于检测到的旋转状态校正的电流的大小模式,并提供校正电流以旋转旋转构件。 当介质在旋转方向上的长度,介质在轴向上的长度或介质的类型改变时,控制单元在开始打印之前产生单旋转电流曲线,并且重复地提供校正的电流 到电机打印图像。

    • A liquid storing device includes a storage unit that stores a liquid to be consumed and a rotation member inside the storage unit that rotates around a rotation axis. A blade member is installed to the rotation member to be movable in the axis direction of the rotation axis with respect to the rotation member and has a specific gravity smaller than that of the liquid. A detection member detects the blade member when the blade member is located vertically at a detection position. When the rotation member rotates in one direction, the blade member agitates the liquid while moving toward the lower side of a liquid surface of the liquid in the vertical direction along the axis direction in accordance with rotation of the rotation member. When the rotation member stops rotating, the blade member floats toward the liquid surface due to buoyancy of the liquid.
    • 液体储存装置包括存储单元,该存储单元存储要消耗的液体,以及旋转构件,其围绕旋转轴旋转。 叶片构件安装到旋转构件上,以能够相对于旋转构件在旋转轴线的轴线方向上移动,并且比重小于液体的比重。 当刀片构件垂直定位在检测位置时,检测构件检测刀片构件。 当旋转构件沿一个方向旋转时,叶片构件随着旋转构件的旋转而沿着轴线方向沿着垂直方向向液体的液面的下侧移动。 当旋转构件停止旋转时,叶片构件由于液体的浮力而向液面浮起。
