<P>PROBLEM TO BE SOLVED: To provide a dust collector for a sheet work which can feed the sheet work smoothly by preventing the sheet work from being adsorbed by an air spraying opening. Ž<P>SOLUTION: A lower dust-removing head 1 corresponding to the lower surface M<SB>1</SB>of the sheet work M is disposed to remove dust R attached to the sheet work M. The lower dust-removing head 1 has an upstream suction inlet 3 and a downstream suction inlet 4 for sucking air and the dust R, and a lower spraying nozzle 6 arranged between the upstream suction inlet 3 and the downstream suction inlet 4 and having a discharge slit 5 for spraying air. In the front and back vicinities of the discharge slit 5, sheet work contact preventing rotors 7 are attached which prevents the sheet work M from contacting the upper surface 9a of the body 9 of the lower dust-removing head 1.
