To reduce a load to a motor at the time of high speed operation by providing a specified number or more of can surfaces for completing a series of one cycle operation at the circumferential surface of a cam.
At least two or more of cam surfaces are provided on the circumferential surfaces of a cam 5, and two cam curves identical to each other are provided on the circumferential surface of the cam 5. One of the cam curves of the cam 5 is turned half by a motor of a drive part, which is taken as one cycle operation of a mechanism, so that a feeding lever of an electronic parts feeding device is operated. Also, when the cam 5 is turned half further, the feeding lever of the device is operated similarly according to the other cam curve. With the cam mechanism according to the constitution, the rotation number of the cam 5 is made half for high speed operation. Accordingly, a load to a motor 7 is reduced, and also the rotational peripheral speed and acceleration of the cam 5 can be reduced.
