摘要

This tool magazine device (12) is equipped with: a rail (14) that is annularly formed and has a separation section (141) on part of the circumference; and a holding ring (15) that is positioned coaxial to the rail (14) and is rotated by a driving motor (16). The holding ring (15) is provided with multiple holding sections (171) that are open in the axial direction of the holding ring (15). The multiple holding sections (171) are arranged in the circumferential direction of the holding ring (15). A tool pot (18) is held so as to be able to be inserted into and removed from each holding section (171). A conveyance unit (21) sends out the tool pot (18) in a holding section (171) to an exchange position and sends the tool pot (18) into the holding section (171) from the exchange position. A roller (20) supported by each tool pot (18) rolls on the rail (14) along with the rotation of the holding ring (15).
