A counting apparatus for counting objects, such as chicks, passed in succession over a conveyor belt through a light beam present between a light source and a photodetector, in which the photodetector produces a detection signal upon each passage of an object through the light beam, which detection signal is applied to a voltage-to-frequency converter for conversion into a frequency varying in accordance with the magnitude of the detection signal, and which detection signal is also applied to a pulse former for conversion into a count pulse whose width is indicative of the period of time required for an object to pass by; wherein the number of cycles of the frequency is counted in a data counter during the period of time that a count pulse is present, and the count pulse is applied to an object counter in response to the data counter having counted a given number of cycles.
