Abstract: A tool changing device for a tool machine having a tool spindle which can be moved at least in the spindle direction and with which a tool can be engaged in a spindle hand-over position. A tool magazine/storage area houses a tool to be changed in a magazine ready position with an orientation diverging from the spindle direction. A transport device is fitted with a tool holder which, by means of an operating device provided with a driving guide/guide path, swivels the tool about a swiveling axis during its transport from the ready position in the tool magazine and an orientation parallel to the spindle direction. The transport device is designed for an entire transport path between the magazine ready position and a spindle hand-over position. The transport device is aligned with the rotation axis of the stored tool. The swiveling axis runs perpendicularly to the transport direction and the spindle axis.
