An automatic workpiece delivery apparatus includes a support member mounted on a body for vertical movement. A slide bar is supported by the support member for horizontal movement and has a pair of workpiece holders at its opposite ends. First and second cams are mounted on a common cam shaft. First and second cam mechanisms are operable respectively in response to the cam surfaces of the first and second cams. A first displacement transmitting mechanism operatively connects the first cam mechanism to the slide bar for displacing the slide bar horizontally. A second displacement transmitting mechanism operatively connects the second cam mechanism to the support member for displacing the support member vertically. A motor has an output shaft connected to the cam shaft for rotating the first and second cams. The cam surfaces of the first and second cams have such configurations that upon one revolution of the cam shaft, the slide bar and the support member are moved horizontally and vertically, respectively, in a sequential manner, thereby moving the workpiece in a predetermined manner.
