Abstract
A workpiece conveying apparatus for conveying a workpiece disposed in a through hole in a conveying table allows the workpiece to be reliably dismounted from the through hole using compressed gas, suppresses the workpiece from unintentionally jumping out because of residual pressure of the compressed air, and increases the conveying efficiency. In an electronic-component conveying apparatus, a conveying table is arranged to face a conveying surface of a conveying stage, with an electronic component disposed in a through hole in the conveying table. When the conveying table is rotated, the electronic component is conveyed. The conveying surface has an exhaust hole at a position where the electronic component is to be dismounted. The total area of the opening of the exhaust hole in the conveying table is larger than the area of the surface of the electronic component facing the conveying surface of the conveying stage.
