Abstract

An electric-component transferring apparatus including a component holder which holds an electric component, a shaft member whose lower end portion supports the component holder, a movable member having a support hole which supports the shaft member such that the shaft member is rotatable about an axis line relative to the movable member and is movable relative to the movable member in an axial direction parallel to the axis line, a moving device which moves the movable member in a direction intersecting the axis line of the shaft member, a piston which is supported by the shaft member such that the piston is not movable relative to the shaft member in the axial direction of the shaft member, the support hole including a portion defining a cylinder bore which cooperates with the piston to provide an air-pressure-operated cylinder device, a driven wheel which is substantially integral with the shaft member, and a drive wheel which is supported by the movable member such that the drive wheel is meshed with the driven wheel to rotate the driven wheel, one of the drive wheel and the driven wheel having a length which assures that the drive and driven wheels are kept meshed with each other when the driven wheel is moved with the shaft member in the axial direction thereof.
