The input conveyor unit 11 is started in advance by an operation switch (not shown) or is started by detecting a placed document S by a sensor (not shown), and the document conveyer S is roughly cut off downstream. To 12.

In the rough cut-out section 12, the document-shaped package S placed on the input conveyor section 11 is divided into several bundles by the independently driven inclined conveyors 13a, 13b, and 13c, and is conveyed to the thick extractor 20. At this time, the rough thickness detection 14A detects whether or not there is a large-size document luggage (indicated by a symbol S1) having a thickness of a certain value or more in the document luggage S.
When sending the document luggage S from the rough cutout unit 12 to the thick material extraction unit 20, when the large thickness luggage S1 having a certain thickness or more is detected by the rough thickness detector 14A, the inclined conveyor 13a , 13b are stopped, and only the inclined conveyor 13c is conveyed, and the document-shaped package S is conveyed to the thick extractor 20 with a minimum amount.

Thereafter, the rough thickness detector 14B of the thick extractor 20 also detects whether or not the document S is a large document S1 having a certain thickness or more, and based on the detection result, determines the thickness of the large document S1. The tilting conveyor 22 of the object extracting unit 20 is operated.
In other words, if the size of the document luggage S is within the standard that is less than a certain thickness, the tilting conveyor 22 of the thick extractor 20 receives the document luggage S in a horizontal state, and then the tilting conveyor moves downward. The document package S is tilted by 45 degrees, the lower ends of the document package S are aligned, and the document package S is transported to the downstream leveling transport section 24. Thereafter, the tilting conveyor 22 returns to the initial horizontal state in order to receive the next document baggage S.
