Abstract:
1. An egg counter for counting eggs which are conveyed on an egg collection conveyer comprising a first light emitting element array, a second light emitting element array, a light receiving element array provided between said first and second light emitting element arrays, and a controller for processing the light reflected from the respective eggs and received by the light receiving element array, said first and second light emitting element arrays and said light receiving element array being arranged such that the light emitted from the each of the light emitting elements of the first and second light emitting element arrays is reflected from the surface of the egg that is passing just under the light receiving element array, and the reflected light is then received by the light receiving element array, said controller measuring the light intensity of the reflected light, detecting the peak value of the light intensity, and counting the egg passing just under the light receiving element array on the basis of the two peak values of the light intensity with respect to the intensities of the light emitted by the first and second light emitting element arrays.
