Stirring device and stirring method

The invention provides a stirring device and a stirring method. When the stirring action is finished, the box can be kept in a proper posture. A stirring device (1) is provided with: a rotation holding unit (12) that rotates while holding a cartridge (2) that accommodates ink that is a liquid in which a solute (L2) settles in a solvent (L1) due to standing; a rotation mechanism (10) that rotates the rotation holding unit (12); and a tension coil spring (133) and the like as a spring member that, when the operation of the rotation mechanism (10) is stopped in a state in which the cassette (2) is in a "second attitude" different from a "standard stop attitude", i.e., a "first attitude", corrects the stop position of the rotation holding unit (12) so that the cassette (2) is in the "first attitude". 本申请提供搅拌装置和搅拌方法。在搅拌动作结束时，能够使盒成为适合保持的姿态。搅拌装置(1)具备：旋转保持部(12)，在保持有收容墨的盒(2)的状态下进行旋转动作，所述墨为溶质(L2)由于静置而在溶剂(L1)中沉降的液剂；旋转机构(10)，使旋转保持部(12)旋转动作；以及作为弹簧构件的拉伸螺旋弹簧(133)等，该弹簧构件作为姿态控制部(第二姿态控制部)，在旋转机构(10)的动作在盒(2)处于与"标准的停止姿态"即"第一姿态"不同
