PROBLEM TO BE SOLVED: To make a worker appropriately confirm the inside of an apparatus while appropriately guaranteeing work by a work machine, in the work machine with which a transparent part is provided in a cover housing.SOLUTION: In a packaging machine 16 including a glass cover 82 provided in a cover housing 80 which covers a base, for watching the inside of the cover housing 80, light transmissivity of the glass cover 82 can be changed. Thus, in accordance with a situation of packaging work in the packaging machine 16, the light transmissivity of the glass cover 82 can be changed and while appropriately guaranteeing the packaging work, the worker can be made appropriately confirm the inside of the apparatus. Specifically, in the case where an imaging apparatus for imaging an electronic component or a circuit board is being operated, the light transmissivity is made low and in the case where the imaging apparatus is being stopped, the light transmissivity is ade high, thereby suppressing influences of a disturbance light during imaging by the imaging apparatus.SELECTED DRAWING: Figure 1 |
