Summary:PROBLEM TO BE SOLVED: To prevent an accident of clogging of a powder that is caused by a conveyance member reaching a fullness detection chamber, even when the conveyance member continues a powder recovery operation after fullness is detected in the fullness detection chamber.SOLUTION: A powder recovery device 11 comprises: a recovery container 1 including one or more recovery ports 2 that recover a powder G conveyed from a powder processing part 10, a powder storage chamber 3 that initially stores the powder G recovered from the recovery ports 2, and a fullness detection chamber 4 that is provided adjacent to the powder storage chamber 3, stores the powder G overflown from the powder storage chamber 3, and detects whether the powder storage chamber 3 has become full with the powder G stored therein; a covering member 6 that covers an upper part of the fullness detection chamber 4; a conveyance member 7 that conveys the powder G stored in the powder storage chamber 3 toward the fullness detection chamber 4; and an opening/closing door 8 that is provided openably/closably in a part of the covering member 6, and can be opened when the powder G stored in the fullness detection chamber 4 is charged to a position in contact with the covering member 6, by a pressing force of the powder G from the inside of the fullness detection chamber.SELECTED DRAWING: Figure 1 【課題】満杯検知室での満杯検知後に搬送部材による粉体の回収動作を継続したとしても、満杯検知室に至る搬送部材による粉体の詰まり事故を未然に防止する。【解決手段】粉体回収装置１１として、粉体処理部１０から搬送された粉体Ｇを回収する一若しくは複数の回収口２、当該回収口２から回収された粉体Ｇを最初に収容する粉体収容室３、及び、粉体収容室３に隣接して設けられ、粉体収容室３から溢れた粉体Ｇを収容して粉体収容室３に収容された粉体Ｇが満杯に至ったか否かを検知する満杯検知室４を含む回収容器１と、満杯検知室４の上方を覆う覆い部材６と、粉体収容室３に収容された粉体Ｇを満杯検知室４に向かって搬送する搬送部材７と、覆い部材６の一部に開閉可能に設けられ、満杯検知室４に収容された粉体Ｇが覆い部材６に接触する位置まで充填され且つ当該粉体Ｇによる内部からの押圧力によって開放可能な開閉扉８と、を備える。【選択図】図１
