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.

The present invention discloses a screen printing machine having a position adjusting means for carrying out adjustment of position of a material to be printed having a plurality of alignment marks in a direction of X, Y and .theta.. The adjusting means comprises a placing means for placing and positioning the material to be printed, a means for displacing the placing means in a direction of X and moving and carrying the placing means from a recognition station to a printing station, and a means for displacing the placing means in a directin of Y. The displacing means is composed of a mechanism in which both side portions of the placing means are respectively independently displaced in the direction of Y to make adjustment of positions of the placing means in the directions of Y and .theta.. The position adjusting means further comprises a recognition means for recognizing alignment marks marked on the material to be printed placed on the placing means and a displacement means for displacing the placing means in response to the recognition of the marks by the recognition means, the recognition means being moved in a direction at right angles to the carrying direction of the material to be printed.
