Abstract
In order to horizontally position a chip part held by a holding unit by a closing operation caused by relative movement of at least two parts of opposing positioning pawls, a setting unit sets information concerning an interval between opposing positioning pawls of each of the two pairs and information of a size of the chip part, a memory unit stores the information set by the setting unit, a calculating unit calculates a distance for increasing a relative moving speed of the positioning pawls at the start of the closing operation and a distance for reducing the relative moving speed at the end of the closing operation on the basis of the information stored in the memory unit, and a control unit controls a driving source for driving the positioning pawls on the basis of the calculation result of the calculating unit, thereby variably controlling the moving speed at the high-speed moving distance of the positioning pawls in accordance with the size of the chip part to reduce a moving time of the positioning pawls required for positioning, performing a positioning operation at high speed.
