PURPOSE:To greatly simplify a measuring piping system of chemicals by providing one liquid chemical measuring station which measures several kinds of chemicals into a pot and a pot conveyor which conveys this pot to prepn. tanks. CONSTITUTION:Various chemical stock tanks 1a-1d, 1e-1h, 1i-1l necessary for preparation of a photographic coating liquid are respectively grouped and the chemical measuring stations A, B, C which measure these chemicals and supply the same to the pot 5 are provided. The pot conveyor 6 which conveys the chemicals in the pot 5 to hoppers H11-Hn1 of the various prepn. tanks 81-8n is disposed. As a result, the measuring piping systems for the chemicals can be made respectively into one system alone and the piping systems which are heretofore 1Xn are decreased to l pieces and are decreased by 1/n when the number of the chemical stock tanks is designated as l and the number of the prepn. tanks as (n).
