Abstract
To provide a powder suction discharge device capable of sucking and discharging powders.SOLUTION: The present invention includes: a pipe; a container connected to the pipe; a valve for opening or closing the flow passage of the pipe; and a pressure reduction mechanism for making the pressure of the inner space of the container a negative pressure. Powders are sucked into the container through the pipe in a first state in which the valve is opened and the pressure reduction mechanism is driven, the sucked powders are stored in the container in a second state in which the valve is closed, and the stored powders are discharged through the pipe in a third state in which the valve is opened.SELECTED DRAWING: Figure 1
