ABSTRACT:
An electronic parts-mounting apparatus includes an index unit which has an output shaft and is connected to a reduction gear for being driven thereby. A rotatable table is connected to the index unit and driven thereby into intermittent rotation. At least one camshaft is connected to the output shaft of the index unit. At least one cam rigidly mounted on the at least one camshaft is in contact with at least one cam follower associated therewith. The output shaft of the index unit is caused to rotate at a uniform rotational speed in which one rotation thereof corresponds to a plurality of repetition periods of intermittent rotation of the rotatable table. The at least one cam has a cam profile formed such that one rotation of the at least one cam causes a plurality of repetition periods of operation of the at least one cam follower in contact therewith, and at the same time each of the plurality of repetition periods of the operation of the at least one cam follower is identical to each of the plurality of repetition periods of the intermittent rotation of the rotatable table.
