A method for producing biochemical analysis data includes the steps of collecting light selectively released from a plurality of light releasable regions two-dimensionally formed to be spaced apart from each other in a sample placed on a sample stage by a plurality of light guide member each of which is disposed to face one of the plurality of light releasable regions, leading the thus collected light to a light detector and photoelectrically detecting the light by the light detector. According to this method, it is possible to produce biochemical analysis data having high quantitative characteristics by photoelectrically detecting light emitted from a plurality of light releasable regions even in the case where the plurality of light releasable regions labeled with a labeling substance are formed in a sample at a high density.

A biochemical analysis data producing method includes the steps of selectively storing one of radiation energy and light energy in a plurality of stimulable phosphor layer regions two-dimensionally formed in a support of a stimulable phosphor sheet and spaced apart from each other, moving the stimulable phosphor sheet and a stimulating ray relative to each other in a main scanning direction and a sub-scanning direction, sequentially irradiating the plurality of stimulable phosphor layer regions so that energy of the stimulating ray projected onto the plurality of stimulable phosphor layer regions per unit area is higher than that projected on regions other than the plurality of stimulable phosphor layer regions, thereby exciting stimulable phosphor contained in the plurality of stimulable phosphor layer regions, and photoelectrically detecting stimulated emission released from the stimulable phosphor layer to produce biochemical analysis data. According to this method, it is possible to effectively prevent the stimulating ray from entering a neighboring stimulable phosphor layer region to be next stimulated as the stimulating ray is scanned and thus prevent stimulable phosphor contained in the neighboring stimulable phosphor layer region from being excited to release radiation energy or light energy stored therein, and, therefore, biochemical analysis data having an excellent quantitative characteristic can be produced in a desired manner.
