Zusammenfassung:	To enable a tool to be exchanged automatically in a space narrower than usual in a shorter tool replacement time at an automatic tool exchange device.SOLUTION: An automatic tool exchange device is provided with: one arm 11 which can rotate; a first hand 12 and a second hand 13 which are provided at different positions in a longitudinal direction of the arm 11 and can grip a tool 50. One of the first hand 12 and the second hand 13 grips a first tool 50a to remove the first tool 50a from a spindle 6a and the other of the first hand 12 and the second hand 13 attaches a second tool 50b different from the first tool 50a to the spindle 6a from which the first tool 50a is removed.SELECTED DRAWING: Figure 1 【課題】自動工具交換装置において、短い工具交換時間で、通常よりも狭い空間において自動で工具を交換できるようにする。【解決手段】回動可能な１つのアーム１１と、このアーム１１の長手方向の異なる位置に設けられ、それぞれ工具５０を把持可能な第１ハンド１２及び第２ハンド１３とを設ける。第１ハンド１２及び第２ハンド１３の一方が、主軸６ａから第１工具５０ａを掴んで取り外し、第１ハンド１２及び第２ハンド１３の他方が、第１工具５０ａとは別の第２工具５０ｂを第１工具５０ａが取り外された主軸６ａに取り付けるようにする。【選択図】図１
