A manual handle can be detachably provided on the winding shaft, and a lid body for covering at least both filter cloth storage chambers can be provided on the case. The method of winding one roll-shaped filter cloth on the other side of the winding shaft is not limited to the manual winding method as described above, and an automatic winding method using a dry battery or a power source can be adopted.

[0008]

[Action]

 Since a through hole is formed in a part of the case so as to face the stretched portion of the roll-shaped filter cloth, the above-mentioned transparent portion of the roll-shaped filter cloth is formed by using this through-hole as a passage for the processing gas. The part facing the hole functions as a filter for separating and collecting. Before the roll-shaped filter cloth part becomes clogged or becomes dirty during use, the winding shaft can be rotated manually or automatically to wind up the length of the dirty part of the filter cloth. Thus, the new roll-shaped filter cloth is stretched and collected so as to face the through hole. This operation is repeated until the roll-shaped filter cloth is used up. When all the roll-shaped filter cloth has been used, the lid may be opened and taken out from the filter cloth storage chamber, and replaced with a new roll-shaped filter cloth.
