PURPOSE:To provide small diameter bowls as well as sufficient vibrating force by arranging an electromagnet of a vibrator at the inside and a leaf spring for elastically supporting bowls and weight member relative to a base at the outside below the bowls. CONSTITUTION:In a multiple bowl feeder A consisting of a plurality of bowls 1 and a vibrator 2 independent from each other, a base 5 of the vibrator 2 is elastically supported by a strut 3 through a cylindrical type vibration insulating rubber 6 and mounts a weight member 9 movable circumferentially. The weight member 9 is provided on three outer peripheral portions with leaf spring mounting portions 9a at equal intervals, and each pair of leaf springs 10 support portions between the mounting portion 9a and a leaf spring mounting portion 5a projecting to the outer periphery of the base 5. On the other hand, each pair of leaf springs 22 support portions between a flange member 19 fixed to the bottom of the bowl 1 and said mounting portion 5a. And an electromagnet C is disposed in the inner peripheral portion of the weight member 9 and opposed to attracted iron pieces 17 fixed to the bowl 1 above said electromagnet. |
