Abstract
A work piece conveyor whose structure is simplified and downsized with the intention of achieving cost reduction, an improved degree of freedom in setting a motion pattern and improved productive efficiency. The workpiece conveyor is such that a cross bar carrier for supporting a cross bar provided with vacuum cups is movably attached, through a linear movement mechanism, to a feed lever which is oscillating-driven along a workpiece conveying direction, thereby making the relative distance between the center of oscillation of the rocking element and the cross bar variable.
