A sensor of articles and discontinuities in general but particularly suited for counting newspapers arranged in overlapping fashion and flowing past the counter in a stream. A trip is engaged by the leading edge of a paper, or other article, and is moved in the direction of stream movement to actuate a switch enabling the use of an external power source to effect a count. The count having been made, the trip lifts out of the paper stream, is reset to an initial position, and is returned to the stream. The switch action which accomplishes the count is used to initiate forcible removal of the trip from the stream followed, after a time delay, by forcible return to the stream.
