PROBLEM TO BE SOLVED: To provide an injection molding machine having a liftable signal lamp, which has a structure allowing the height of the signal lamp to be freely moved up and down in a manual or automatic manner, without interference between the signal lamp and surrounding objects, capable of securing the height required for the signal lamp.SOLUTION: An injection molding machine 1 allows the entire injection molding machine to be controlled by a control device not shown in drawing. A lifting part 4 having a signal lamp 5 is fitted to the top face of a cover 3 of the injection molding machine 1. The lifting part 4 can move the signal lamp 5 up and down in a manual or automatic manner. The signal lamp 5 is moved down with the lifting part 4 contracted, such that transportation means 6 causes no collision or contact between a freight 7 and the signal lamp 5 (refer to Figure 1 (a)). In a state that no collision or contact between a freight 7 and the signal lamp 5 is caused, the lifting part 4 is extended, so that the signal lamp 5 is located in an upper position. The height of the signal lamp 5 can be thus changed by extending or contracting the lifting part 4. |
