    Abstract: A brick-like article feeding mechanism with nearly square travel path and quick returning function includes an eccentric apparatus composed of a slide block and a slide channel and cooperative spur gear and internal gear with a gear ratio of 1:4. In cooperation with synchronously driving sprockets, the pushing arms for feeding the article travel through a nearly square path. One side of the square travel path (loading travel) costs a period of time equal to the sum of the time cost by the other three sides (unloading travel) so as to achieve a quick returning function and synchronous operation.
