PROBLEM TO BE SOLVED: To decrease the number of parts and reduce the production cost of the subject apparatus. SOLUTION: This beating position changing apparatus is integrated to a reed frame leg 3 subjected to principal motion with a driving apparatus 5 and is provided with a driving element 11, transmission parts 12, 13 and a kinetic mechanism 14. The kinetic mechanism is connected to the transmission parts 12, 13 at one end and to a reed-gyration shaft 2 at the other end. The reed gyration shaft 2 is rotatably attached to the reed frame leg 3. The beating position of the reed gyration shaft 2 can be changed by the driving element 11. |
