feeder (10) has a first housing portion having an elongated planar member (15) (14). The second housing portion (16), when the closed position, so that tubular space having a lower opening portion is formed, is movable between an open position and a closed position. Each of the plurality of base (22) has a first edge thereof (24), proximate to the first surface of the elongated planar member (15) (20) is arranged pivotally. Protrusions (28), as extending through openings formed in the elongated planar member (15) to (27), provided on the first edge of each platform (22) (24). The support member (26), on the second opposite surface of the elongated planar member (15) (21), each opening (27) is provided in the vicinity. Each support member (26) has a first position to maintain in the support member (26) is fitted to the projecting portion (28) base (22) in a horizontal position, the movable in a vertical position base (22) it can be moved between two positions.FIELD 3供給装置(10)は、伸長平面部材(15)を有する第1筐体部(14)を有する。第2筐体部(16)は、閉鎖位置の時に、下方開口部を有するチューブ状の空間が形成される様に、開放位置と閉鎖位置との間を移動可能である。複数の台(22)の各々は、その第1縁部(24)が、伸長平面部材(15)の第1表面(20)に近接して、枢動可能に配設されている。突起部(28)は、伸長平面部材(15)に形成された開口部(27)を通って伸びる様に、各台(22)の第1縁部(24)上に設けられる。支持部材(26)は、伸長平面部材(15)の第2反対面(21)上の、各開口部(27)近傍に設けられる。各支持部材(26)は、支持部材(26)が突起部(28)と嵌合して台(22)を水平位置に保つ第1位置と、台(22)が垂直位置に移動可能な第2位置との間を移動することができる。【選択図】図3
