PURPOSE:To efficiently perform a tool replacement work by providing a part of the annular groove of a main body of a magazine with a radial notch groove, which is fitted with a swivelling body so that a tool holder may be directly taken out of the main body of a magazine through motion of said swivelling body. CONSTITUTION:An annular groove 13 is provided on the outside surface of a main body 11 of a magazine along its circumference. The groove 13 is fitted with a freely moving tool holder 16, which holds a boss 15 of a tool 14, through bearings 17, 18. A radial notch groove 57 is formed at the bottom of the groove 13 by cutting in from the circumference surface of the main body 11. A fan shape swivelling body 71 is rotatably fitted between the notch groove 57 and a guide board 61, fixed along both sides of said groove 57. Further, the swivelling body 71 is provided with a tool holder containing groove 73 and a tool holder passing groove 74. The tool holder may be taken out directly from the main body of the magazing by swivel motion of the swivelling body 71 and, under this taking-out condition, the old tool storing position may be selected through the tool holder passing groove 74. |
