First, when the user applies the power by operating the operation panel 19 formed in the main body 10, the drive motor 26 is rotated. When the drive motor 26 rotates, the rotational force is transmitted through the chain 27 to rotate the rotation shaft 24. When the rotary shaft 24 is rotated, the disk-shaped rotary blade 24 formed on the rotary shaft 24 is rotated.

Next, when the document is inserted through the document inlet 12, the end of the document reaches the rotary blade 24a once. When the end of the document is inserted between the rotary blade 24a and the blade 22a, it is sucked between the rotary blade 24a and the blade 22a. The document sucked between the rotary blade 24a and the blade 22a is cut into strips and dropped into the collecting box 30.

As described above, when the sedans generated through the sedan work of the document are stacked in the collecting box 30 and reach the upper end, the pump 54 is operated as shown in FIG. 6 to spray water from the water tank 52. Through the spray to the inside of the collecting box (30). Here, since the Laval nozzle 58 is formed at the tip of the injection pipe 56, water passing through the injection pipe 56 is atomized and injected into the collecting container 30. Thus, water can be evenly penetrated between the narrow gaps of the sedans accommodated in the collection box (30).

Next, as shown in FIG. 7, the lifting cylinder 44 is driven to control the piston rod 44a to descend. When the piston rod 44a is lowered, the pressure plate 42 connected to the piston rod 44a is lowered. When the pressure plate 42 is lowered, the sedan is started to be compressed. At this time, since the three-single contains moisture by the water injected from the injection pipe 56, not only dust is generated, but also the cohesive force is improved and is easily blocked. In addition, when the sedan is compressed by the pressure plate 42, the lifting cylinder 44 is driven again as shown in FIG. 8 to control the piston rod 44a to rise. When the piston rod 44a is raised, the pressure plate 42 connected to the piston rod 44a is raised to collect the sedans 30 again.

The sedans collected in the collection box 30 as described above can be further compressed by the lifting cylinder 44 by repeatedly performing the water spraying operation through the water spray unit 50 and the compression by the compression unit 40. When the density of the cutaway is increased to such an extent, the door 16 of the main body 10 and the carrying out door 32 of the collecting box 30 are opened to carry out the cutaway block compressed by the pressure plate 42 to the outside.
