Abstract
Provided is a tool magazine apparatus that has excellent workability and is capable of being downsized. A tool replacement device includes a fixed frame installed in an opening portion provided at a predetermined position of a tool magazine, a swivel frame disposed inside the fixed frame so as to be rotatable about a swivel axis extending in a vertical direction, and a tool replacement rack fixed to the swivel frame. The swivel frame is rotated to a deliverable position at which the tool replacement rack is parallel to a tool rack inside the tool magazine to enable a tool to be delivered between the tool replacement rack and a tool transfer device, and to a replaceable position at which the tool replacement rack is located outside the tool magazine to enable replacement of old and new tools.
