Viscous material supply device, coating sheet used for viscous material supply device, viscous material supply method and mounting method of coating sheet

摘要

To provide a viscous material supply device facilitating removal operation of viscous material that could be adhered to a platen, a covering sheet used in the viscous material supply device, and a viscous material supply method.A viscous material supply device 100 according to the present invention includes: a tank 10 provided with a storage space 11 storing viscous material; a piston 20 slidably inserted into the tank, and is provided with a pressing surface 22 that presses the viscous material and a suction passage 23 through which the viscous material inside the tank flows by pressing force of the pressing surface; and a covering sheet 30 including a covering part 31 covering the pressing surface in the piston and a communication hole 32 communicating with the suction passage.
