Zusammenfassung:PURPOSE:To operate smoothly and more automatically a fish body picture input apparatus by detecting automatically the clogging of fish to close a path and thereby prevent the succeeding fish from being transferred therein. CONSTITUTION:When a weight roller is choked with fish, the output of a light receiving sensor is left as L, and electric pulse does not enter the input terminal B of a counting circuit 82 so that subtraction by the counting of said circuit 82 is not carried out. On the other hand, every time a spike drum is rotated by one revolution, fish is sent into a tray while electric pulses are applied from a rotary encoder to the terminal A of the circuit 82 and adding is carried out by the counter so that the accumulated value in the counter exceeds value N0 preset in the circuit 82. Thus the output terminal C of the circuit 82 is held at 1, the output of the light receiving sensor is left as L and the input terminal I and output terminal J of the circuit 85 become L and 1 so that air valves 51, 53 permit a shutter to close a fish path with an air cylinder.
