Plasticizing device, three dimensional molding device, and injection molding device

A plasticizing device comprising:

• a material storage section having a first input port and a second input port and storing plasticization material, the first and second input ports being arranged side by side in a plan view;
• a plasticizing section that has a supply port to which the plasticization material is supplied and that plasticizes at least part of the plasticization material to generate a molding material;
• a connecting pipe having a connecting path connecting the first input port and the second input port to the supply port, the first and second input ports being connected to the connecting path at a same location;
• and
• a control section, wherein
• the material storage section includes a first supply mechanism configured to adjust a supply amount of the plasticization material from the first input port to the connecting path and a second supply mechanism configured to adjust the supply amount of the plasticization material from the second input port to the connecting path, the control section controls at least one of the first supply mechanism and the second supply mechanism to supply the plasticization material to the connecting path, the first supply mechanism has a first slide member having a first hole through which the plasticization material passes, the second supply mechanism has a second slide member having a second hole through which the plasticization material passes, and the first slide member and the second slide member are connected to a slide drive section that slides the first slide member and the second slide member via biasing members.
