PURPOSE:To accurately position a stick not only in lateral directions but also in elevational directions, to be commonly applied to the sticks of various shapes and sizes thereby to obtain a positioning device of a simple structure by first positioning the stick laterally and then positioning it vertical. CONSTITUTION:A rod 12, driving means 11 for elevationally driving the rod 12, a member 13 connected to the lower end of the rod 12 to press a stick 1 in contact with the upper surface of the stick 1 for positioning the stick elevationally, and a member 23 connected through an elastic member 22 to the rod 12 to rotate in response to the elevational movements of the rod 12 to press the stick 1 in contact with both side surfaces of the stick 1 for positioning the stick 1 laterally are provided. When the rod 12 is moved down, the stick 1 is laterally positioned by the member 23, and then elevationally positioned by the member 13. The member 23 is so, for example, is rotated that rotary plates 15A, 15B are rotated around stationary shafts 14A, 14B as centers when a plate 20 is pressed down through a spring 22. |
