Abstract: An aligning and feeding device capable of reliably aligning objects having a plane shape with an unequal ratio of length to width longitudinally and feeding them is provided. An aligning and feeding device has a rotary table 2 horizontally rotatable, drive means 3 for rotating the rotary table 2, a supply mechanism for supplying objects to be aligned onto the rotary table 2 and a guide mechanism 7 for defining a conveying path for the objects to be aligned conveyed by the rotary table 2. The guide mechanism 7 has an introduction guide 11, first pair of alignment guides 16, second pair of alignment guides 19 and pair of discharge guides 23 which each has a guide face and are disposed sequentially along the conveying path for the objects to be aligned.
