ABSTRACT:
A lead frame conveying apparatus comprises a driving force converting unit for transmitting to a frame receiving arm a horizontal reciprocating linear motion of an elliptic motion of a timing belt placed over two timing pulleys between the centers of the timing pulleys and converting semicircular motions at both ends of the horizontal reciprocating linear motion into vertical reciprocating linear motions by employing rolling contact for absorbing the horizontal component thereof and transmitting the vertical reciprocating linear motion to the frame receiving arm so as to put the frame receiving arm into a rectangular motion. The apparatus thus requires only one induction motor as a driving device.
