摘要： A supply apparatus for prism-shaped chip components has two relatively movable taking-in members. When the members move relative to each other, flat surfaces thereof contact each other and a parallel space is formed between the upper portions of the two taking-in members. Relative movement of the two talking-in members causes the components in a storage chamber to enter the parallel space between the upper portions of the two taking-in members. The components entering the parallel space have the same thickness-wise orientation and are lengthwise in a supply passageway in a one by one in a state. The components move downward by gravity in the supply passageway and then in a discharge passageway.
摘要翻译：用于棱柱形芯片部件的供应装置具有两个相对可移动的接纳部件。当构件相对于彼此移动时，其平坦表面彼此接触，并且在两个取入构件的上部之间形成平行的空间。两个通话部件的相对运动导致存储室中的部件进入两个取入部件的上部之间的平行空间。进入平行空间的部件具有相同的厚度方向，并且在一个一个状态下在供给通道中纵向延伸。部件通过供给通道中的重力向下移动，然后在排放通道中移动。
