The present invention provides the packed soy sauce-containing liquid seasoning, containing the following, ,, and : sodium\u20022. The dot patterns are optically read, and a density profile representing change in density in the second direction of a read image of the dot patterns is calculated. A repairable clay core insert or various replaceable target inserts may be used including foam or packed cotton. Further, when an output A of the first logic operation circuit 1a changes from the high level to the low level, the corresponding PMOS transistors Q10 and Q11 are turned off, and thus the PMOS transistors Q10 and Q11 do not prevent a change in the output of the first logic operation circuit 1a, thereby increasing the operating speed of the semiconductor integrated circuit.
