<p>A dispenser for applying creamy solder onto a substrate, comprising: a syringe (1) storing therein creamy solder; a needle (2) fixed at the forward end of this syringe (1); and a driving mechanism (3) using a pulse-controlled stepping motor and an eccentrically rotating drive motion. The driving mechanism (3) comprises: a linear guide (10) for guiding a syringe holder which holds the syringe (1), a stepping motor (11), a crank (13) and a connecting rod (14) rotatably supported on the crank and the syringe holder. When, the stepping motor (11) is rotated by a predetermined angle, the crank (13) and the connecting rod (14) are eccentrically rotated in an interlocking relation to the rotation of this stepping motor, and the syringe (1) is upwardly and downwardly moved within a predetermined range through a syringe holder (9). <IMAGE></p> |
