Abstract
Abstract A method and apparatus for selecting an article from a supply of randomly positioned articles and sensing the orientation of the selected article. If the article is properly oriented, it is fed to a work station; if the article is improperly oriented, it is returned to the supply. This sensing mechanism is capable of sensing the proper orientation of different sized articles without any modification. The articles handled by the article feeding mechanism are preferably of the type having opposite side surfaces lying in substantially parallel planes with one surface provided with an indentation or recess of greater depth than the other surface such as buttons.
