Abstract:
A measuring apparatus of the present invention measures the constituent concentration of a specimen after loading into the apparatus a test piece having a test material which develops coloring as a result of a reaction with the constituents of a specimen. When the apparatus detects that the test piece having the test material has been loaded, it automatically begins to measure the constituent concentration of the specimen. That is. after the loading of the test piece is detected, a predetermined time period is measured. During this time measurement, the time period is displayed at a predetermined time interval. After the time measurement of this predetermined time period is terminated, the test material is irradiated with a light, and the intensity of the light from the test material is detected. The constituent concentration of the specimen applied to the test material can be determined on the basis of the reflected light intensity thus detected. Furthermore, this measuring apparatus can detect a reverse insertion of a test piece, and is constructed so as to disable the measurement of the constituent concentration of a specimen if supplementary information to be stored along with measurement information has not been set.

Abstract:
A fluorescence and phosphorescence detection device includes a fluorescence and phosphorescence sensor (10), a data acquiring unit (33), and an emission detection unit (34). The fluorescence and phosphorescence sensor (10) includes a light source (15) that emits an excitation light of a predetermined wavelength, and a photodetection unit (11-14) that detects fluorescence emission and phosphorescence emission excited from the paper sheet by the excitation light. The data acquiring unit (33) acquires a time-series waveform of a signal outputted from the fluorescence and phosphorescence sensor in response to the detection of the emission in the photodetection unit (11-14). The emission detection unit (34) detects the fluorescence emission from the time-series waveform of a period in which the excitation light is emitted from the light source (15) and detects the phosphorescence emission from an attenuation curve appearing on the time-series waveform of a period in which emission of the excitation light from the light source is stopped.
