Abstract
The invention can accurately feed flat articles one-by-one. The packing density of flat articles in a hopper section is correctly detected even if they have various and indefinite shapes and conditions, such as mail, envelopes, cards and other flat articles. These articles are transferred from the hopper section to a feed mechanism section, in response to the detected packing density. The flat articles are transferred to the feed mechanism section in accordance with the distance between the centers of the flat articles while they are in the hopper section, the distance inversely corresponding to the packing density of the flat articles. Light reflection is preferably used in order to detect the distance between the centers of the flat articles.
