Counter of objects being transported

摘要

A device for counting objects being transported by transport equipment includes a light projector for projecting a light beam onto the objects being transported, a light receptor for receiving the light beam reflected from the objects being transported and focusing the beam to a point, and a pulse generating means for generating pulses in accordance with the abrupt shift of the focused point of the reflected light beam caused by the ends of the objects being transported. The objects being transported are counted on the basis of the pulses generated by the pulse generating means.
