(EN) A component feeding device located on a rear side of an apparatus body includes a component feed table circulation path within a vertical plane, and a plurality of movers as well as table lifting mechanisms for moving independently a plurality of component feed tables placed within the circulation path. By this arrangement, the component feeding device does not need to be upsized even if the number of components is increased. Also by this arrangement a speedup of component feeding is achieved. By providing a component exchanging device for pulling out a component feed table from a takeout position of the circulation path and transferring it up to an exchange position on a front side of the apparatus body, it is possible to carry out the exchange of the component feed tables on the front side of the apparatus body.
