PURPOSE:To obtain a positioning device for multiple types of solid state elements by attracting the elements to an attraction base, sequentially closing X- and Y-axis holders by a cam to hold the elements, stepwisely centering the elements in Xand Y-axis directions, and opening or closing a pair of holders by an interlocking mechanism in the X- and Y-axis directions. CONSTITUTION:When a chip 2 is placed on an attraction base 31, a discharge pump is operated, the chip 2 is held at the base 31, and cam 51 is rotated counterclockwise. The cam 51 releases pressing of Y-axis holders 35, 36 to a cam follower 53 by the rotation at this angle alpha, the Y-axis holders are closed by the spring 55 of an interlocking mechanism 38 to hold the chip 2, thereby centering it in the Y-axis direction. Then, the cam 51 releases pressing of X-axis holders 33, 34 to a cam follower 53 by the rotation at the angle beta, the X-axis holders are closed by the spring 54 of an interlocking mechanism 37 to hold the chip 2, thereby centering it in the X-axis direction. As a result, the chip 2 is centered and positioned in both X- and Y-axis directions. |
