As shown in FIG. 3 and FIG. 4, for example, when the first turret device 12A is not placed at the original position (when the predetermined conditions of the present disclosure are not satisfied), the control device 22 turns off the original position lamp 57A and the original point return lamp 84.
  • the control device 22 When the control device 22 receives a touch operation on the original position lamp 57A in the turned-off state at the touch panel 26, the control device 22 displays the operation screen 71.

  • the original position lamp 57A is not only used as an indication lamp, but also has a function as a button for displaying the operation screen 71, thereby improving the convenience of the operator.
  • the control device 22 also lights the original position lamp 57A when the conditions for placing the first turret device 12A in the original position (an example of a predetermined position in this disclosure) are met.
  • the control device 22 displays a movement instruction button 82 on the operation screen 71 that accepts an instruction to slide the first turret device 12A, and controls the first sliding device 13A based on the operation of the movement instruction button 82 to slide the first turret device 12A.
  • This allows the first turret device 12A to be moved to the original position by operating the movement instruction button 82 displayed on the operation screen 71 while checking the lighting status of the original position lamp 57A and the origin return lamp 84.
  • the worker can quickly place the first turret device 12A in the original position by confirming that the original position lamp 57A is lit and ceasing the operation of the movement instruction button 82.

Then, as shown in FIG. 5, when the first turret device 12A is placed in the original position, that is, when the machine tool 10 satisfies a predetermined condition, the control device 22 simultaneously lights up the original position return lamp 84 and the original position lamp 57A. As shown by hatching in FIG. 5, for example, the original position lamp 57A is lit in the same color as the original position return lamp 84 or in a different color. This makes it possible to confirm the original position lamp 57A on the status display screen 51 side, and to confirm that the first turret device 12A has returned to the original position and the original position lamp 57A has been lit.
  • the control device 22 does not have to turn on the origin return lamp 84 and the original position lamp 57A at the same time.
  • the control device 22 hides the operation screen 71 and displays the status display screen 51 on the touch panel 26. If the first turret device 12A is located in the original position at the timing when the close button 74 is operated to hide the operation screen 71 and display the status display screen 51, the control device 22 may turn on the original position lamp 57A.

Then, when control device 22 receives an operation on home position lamp 57A (a touch operation or an operation of operation switch 27) on operation panel 20, it executes a process of displaying on the touch panel an operation screen 71, which can be operated to transition machine tool 10 to a state that satisfies the predetermined condition (an example of a display process of the present disclosure).
