SCREEN

PROBLEM TO BE SOLVED: To provide a screen which can be small in height size in its transportation and also can smoothly introduce a sorted substance selected by a screening apparatus to a discharge conveyer without making the sorted substance adhere to a chute. SOLUTION: A movable-side chute 34 is arranged in a screening apparatus 25 while a fixing-side chute 32 is arranged at the discharge conveyer 14, and the fixing-side chute 32 and the movable-side chute 34 are superimposed upwards and downwards. Therefore, even though the lower end side of the screening apparatus 25 approaches the discharge conveyer 14, the height size of the screening apparatus 25 in transportation can be kept small without an interference of the fixing-side chute 32 and the movable-side chute 34. Further, the width size of the fixing-side chute 32 arranged at the discharge conveyer 14 can be reduced according to the state that the movable-side chute 34 is arranged in the screening apparatus 25, adhesion of the sorted substance, fell down from the screening apparatus 25, to the fixing-side chute 32 can be controlled and therefore the sorted substance can be smoothly introduced to the discharge conveyer 14.
