A particle supplying apparatus for supplying particles of absorbent material or deodorant material onto a sheet member, comprising: a cylinder part (21, 21a) which is an generally cylindrical member around a rotation axis along a horizontal direction, said cylinder part being rotated around said rotation axis; and a sheet conveying part for conveying a sheet member; and characterized in that in said cylinder part, a portion of the internal space is a particle storage space which stores particles of absorbent material or deodorant material, said cylinder part has a plurality of through-holes arranged in a circumferential direction and is rotated around said rotation axis so that particles are filled into a through-hole out of said plurality of through-holes which faces particles stored in said particle storage space, to eject particles filled in said through-hole outward at a particle supply region provided in a lower portion thereof, said sheet conveying part conveys said sheet member in a direction under said particle supply region, said direction being same as a moving direction of an outer side surface of said cylinder part, and said particle supplying apparatus further comprises: a cover part which spreads from said particle supply region along an opposite direction of a rotation direction of said cylinder part to cover a portion of said outer side surface of said cylinder part and close an outer end of said through-hole filled with particles; and an isolation part which covers a portion of an inner side surface of said cylinder part to isolate a through-hole in said particle supply region from said particle storage space. a cylinder part (21, 21a) which is an generally cylindrical member around a rotation axis along a horizontal direction, said cylinder part being rotated around said rotation axis; and a sheet conveying part for conveying a sheet member; and characterized in that in said cylinder part, a portion of the internal space is a particle storage space which stores particles of absorbent material or deodorant material, said cylinder part has a plurality of through-holes arranged in a circumferential direction and is rotated around said rotation axis so that particles are filled into a through-hole out of said plurality of through-holes which faces particles stored in said particle storage space, to eject particles filled in said through-hole outward at a particle supply region provided in a lower portion thereof, said sheet conveying part conveys said sheet member in a direction under said particle supply region, said direction being same as a moving direction of an outer side surface of said cylinder part, and said particle supplying apparatus further comprises: a cover part which spreads from said particle supply region along an opposite direction of a rotation direction of said cylinder part to cover a portion of said outer side surface of said cylinder part and close an outer end of said through-hole filled with particles; and an isolation part which covers a portion of an inner side surface of said cylinder part to isolate a through-hole in said particle supply region from said particle storage space. a cover part which spreads from said particle supply region along an opposite direction of a rotation direction of said cylinder part to cover a portion of said outer side surface of said cylinder part and close an outer end of said through-hole filled with particles; and an isolation part which covers a portion of an inner side surface of said cylinder part to isolate a through-hole in said particle supply region from said particle storage space.
