Abstract: The invention provides an image reader provided with an automatic document feeder which has a switchback path and can perform a both-faces processing operation, and which makes it possible to simplify the control of a switchback operation and handle a long-sized document sheet without making the diameter of a feed roller large and making the switchback path unnecessarily long.

Abstract: The invention aims at providing an automatic document feeder capable of making the whole apparatus small-sized, simplifying its driving system, improving the speed of reading consecutive document sheets when conveying document sheets to the document reading position of an image reader, surely preventing an image read in the image reader from being distorted, and preventing a document sheet from being jammed.

Abstract: A bottle making machine includes a gob distributing apparatus in which a plurality of molds are arranged in a plurality of rows with equal spaces with each other and a plurality of chutes are arranged at entrance portions of respective molds. The apparatus comprises a plurality of rotation shafts of the numbers corresponding to the numbers of the rows of the molds, a plurality of scoops secured to the respective rotation shafts for distributing gobs to the chutes, respectively, a plurality of servo-motors having output shafts of the numbers corresponding to the numbers of the rotation shafts and a plurality of link mechanisms connecting the output shafts of the servo-motors to the rotation shafts, respectively, to independently drive the rotation shafts by the corresponding servo-motors.
