To provide a device and method for controlling positional displacement of a hand mechanism for ointment that allows a microtube to be inserted efficiently into a rack for storage, and where unreasonable force is prevented from being applied to the rack for storage or a microtube, when the microtube is inserted.
This controlling method comprises a first process of moving a predetermined microtube by a predetermined distance in a state where the microtube is butted on the rack for storage when the bottom of the microtube comes into contact with a lattice-like partition and cannot be inserted, when the microtube is intended to be inserted into a predetermined position of the rack for storage, and a second process of turning the predetermined microtube about the initial position O of the microtube before movement at a radius of the distance when the microtube cannot be inserted, even after movement by the predetermined distance and increasing the predetermined distance by a predetermined amount , when the microtube cannot be inserted, even after one complete lap. Until an insertion position is found or the predetermined distance reaches a predetermined maximum value, the second process is repeated.
