(57) [PROBLEMS] To detect the light emitted from a sample by relatively reciprocating the excitation light and the sample in the main scanning direction by using a motor and a crank mechanism, and to perform biochemistry. Provided is a scanner capable of generating biochemical analysis data with excellent quantitativeness when generating analysis data. Two excitation light sources 1, 2 that emit excitation light A sample stage 70 on which the sample is placed, a condensing optical system 5 that condenses the excitation light on the sample placed on the sample stage and condenses the light emitted from the sample, and a motor 40. And crank mechanisms 41, 43, 4 for converting the rotational motion of the output shaft of the motor into linear motion 4, a main scanning mechanism that reciprocally moves the condensing optical system and the sample stage in the main scanning direction, and photodetectors 7 and 8 that photoelectrically detect light emitted from the sample. And a rotary encoder 82 for detecting the rotation angle of the output shaft of the motor, and a light source control means 81 for controlling the intensity of the excitation light emitted from the excitation light source according to the rotation angle of the motor output shaft detected by the rotary encoder. A scanner characterized by comprising. |
