PURPOSE:To ensure free drops of leaflets from a pool box to an accommodation box without turbulence in their dropping posture by means of simple constitution by making air-escape holes in side boards of the accommodation box used for accommodating bank notes etc. CONSTITUTION:Air-escape holes 16 are formed on both side boards 17 of an accommodation box. Both bottom plates 11 of a pool box 10 are fixed to a revolving axle 14 respectively, while the axle 14 is constituted in such a way that it can open or close the bottom plates 11 simultaneously by means of a motor 15. When bank notes, which have been accommodated in the pool box with their unified front/back surfaces, start dropping after the opening of the bottom plates, they can drop in a stable state keeping horizontal posture because the air under the bank notes can escape through the holes 16 in order to prevent the turbulence in the airflow or pressure within the accommodation box. |
