PROBLEM TO BE SOLVED: To provide an article feeding device simple and compact in structure capable of reducing the number of parts and enabling stable action by eliminating a factor of the generation of rattling and a failure. SOLUTION: The article feeding device 1 is provided with a driving mechanism 4 with a motor 40 as a driving source; and a link mechanism 5 linked to the driving mechanism 4 through a connection arm 6. The link mechanism comprises a pair of front and rear link plates 50, 51 having plate surfaces parallel to each other. Lower ends of the respective link plates 50, 51 have both ends pivotally supported on a fixed base 10 by a pivot shaft 53. A movable base 3 is supported on both ends of support shafts 52 provided on upper ends of the respective link plates 50, 51. The driving mechanism 4 is provided with an eccentric cam 8 provided to a motor shaft 40a. The eccentric cam 8 is eccentrically and supported on one end of the connection arm 6 so as to be turnable by a bearing 60. The other end of the connection arm 6 supports the support shaft 52 of one link plate 51 by a bearing 61 so as to be turnable. COPYRIGHT: (C)2006,JPO&NCIPI
