The present invention relates to an abalone plaque size selector, a plaque transfer unit for transferring abalone plaques supplied from a plaque supply unit along a plurality of unit supply channels partitioned side by side, and a unit for imaging an abalone plaque moving along a unit supply path A screening path adjusting unit that adjusts a movement path to move to a screening path of one of the first screening path and the second screening path according to the size of the camera provided to correspond to the supply path and the rolled-up plaque that has passed through the imaging area of the camera. A discharge chute installed in correspondence with each of the first separating path and the second separating path and discharging the rolled-in plaque through the discharging path, and an opening and closing section for closing and opening the discharging path of the discharging chute, Receiving the image information captured by the camera, determining the size of the rollover, controlling the sorting path adjusting unit to move to the sorting path corresponding to the determined rollover size, and counting the number of rollover plaques entering the discharge chute to the set target number. It has a control unit for controlling the opening and closing of the discharge path to open or close the discharge path corresponding to the opening and closing conditions set for the reached discharge chute.
