<p>In a device for counting a batch of eggs, the eggs (25) are fed sequentially one behind the other through a counting station (13). A light beam (22) is angled so that a discrete pulse (24) is produced from a light activated switch (LAS1) each time the beam is intercepted by an egg. Since only the upper sector of each egg intercepts the beam, a pulse is produced for each egg whether the eggs are contacting one another or spaced apart and regardless of their orientation.</p> |
