Zusammenfassung:	PURPOSE:To allow the easy change of exposing time to the long and short time by using a spiral flow cell for exposing of a photosensitive emulsion. CONSTITUTION:The emulsion which is diluted and is held at a prescribed temp. is delivered at a specified flow rate by a liquid feed pump 41 and is passed through the spiral flow cell 53 provided at the intermediate point of a liquid feed pipe. This emulsion is exposed by an exposure meter 5. The exposure meter 5 consists of a filter device mounted with a light source 50, an ND filter 51 and a color filter 52. The ND filter 51 is so formed that the density varies with time when an optical wedge is moved. The intensity of light varies logarithmically with time and the sensimetry exposing is executed. The exposing time is easily changed to the long and short time in this way.
