PURPOSE:To position a printed board with high accuracy by placing both edge parts of a printed board between moving tables adapted to move in the direction of Y-axis, erecting a fixed pin put in a reference hole of the printed board on a table, and moving a moving pin put in another reference hole of the printed board by a moving means. CONSTITUTION:According to a command of a NC control device, motors 2B, 3B are driven to move moving tables 2, 3 to the space where a printed board 1 is placed. At this time, the space between the stepped parts of the moving tables 2, 3 may be roughly positioned with accuracy of such a degree as to hold the printed board 1. Subsequently, a motor 6B is driven to move a moving pin 5 to a commanded position on an X-coordinate. Thus, the moving tables 2, 3 and the moving pin 5 are moved, and the printed board 1 can be positioned with high accuracy by a fixed pin 4 erected on a table 10 and the moving pin 5. |
