• a plurality of status indicators each of which is configured to indicate a status of one of the plural pairs of punches and dies, one status indicator of the plurality of status indicators being disposed adjacent each of the plurality of punch attachment holes or each of the plurality of die attachment holes;
• an indication status controller that controls the indication status of each of the plurality of status indicators;
• and
• a comparator that compares data of a punch and die pair that is to be exchanged out from the turret of the turret punch press with data of the plural pairs of punches and dies set on the buffer turret apparatus, wherein
• the indication status controller controls each of the plurality of status indicators to indicate, as a comparison result of the comparator, the status of the corresponding one of the plural pairs of punches and dies, the status being an indication of whether or not the corresponding one of the plural pairs of punches and dies is exchangeable.
