PROBLEM TO BE SOLVED: To provide a device for opening/closing a part to take-out a shuttlecock for practicing badminton. SOLUTION: An opening/closing gate is arranged so as to allow even a shuttlecock with a small diameter due to a damage and a new shuttlecock with a standard diameter to smoothly pass or stay at a take-out port. The gate is closed by using a spring. When the shuttlecock passes, an opening/closing gate piece is opened with a rotary axis as a base. The opening/closing is softly performed so as not to damage the shuttlecock. A twist spring, a leaf spring or a flexible material such as sponge is used for the spring. Not only the spring but a magnet can be used for opening/closing the gate. Then the magnets with the same poles, i.e., N-poles or S-poles are adjacently placed so as to utilize repulsive force. In order to rapidly take out the shuttlecock, two or more supply cylinders are bundled and arranged. COPYRIGHT: (C)2006,JPO&NCIPI
