PURPOSE: To uniformly apply paste without pattern inequality by a method wherein a generation pulse rate and a pulse number of a pulse generator for a driver of an XY table for a nozzle are changed and a transfer speed of the nozzle is equalized in straight line applying between separate optical two points. CONSTITUTION: There are provided pulse generators 6x, 6y for generating a specific pulse by an instruction of a CPU 5, and drivers 8x, 8y for drive- controlling an XY table 7 for transferring a nozzle 3 in the XY directions by this generation pulse. When drive-controlling the XY table 7, a transfer speed of the drivers 8x, 8y is decided by an objective constant speed value and an applying distance between separate optical two points. Based on this decision, a generation pulse rate and its pulse number are respectively given to the pulse generators 6x, 6y by the instruction of the CPU 5, and the transfer speed of the nozzle 3 is equalized in straight line applying between the separate optical two points. Thus, paste is uniformly applied without pattern inequality.
