Abstract: To reduce the effect of directly reflected light on a contact-surface side of a contact member, a biological information detector includes a light-emitting part, a light-receiving part, a reflecting part, a protecting part for protecting the light-emitting part, and a substrate. The protecting member is formed from a material that is transparent with respect to a wavelength of the light emitted by the light-emitting part and has a contact member provided with a contact surface in contact with the detection site. Light emitted from the light-emitting part is inhibited from reflecting once on a contact-surface side of the contact member of the protecting part and being incident on a light-receiving region of the light-receiving part.

Abstract: A portable, scanning and analyzing apparatus that uses an integrated scan probe for the scanning operation is described. The integrated scanning probe is formed with a light emitting diode array light source and a photodiode detector array. After a test sample finishes the reaction in test strip paper, a scanner device scans the test paper to collect the optical signals at variable, consecutive intervals along the scanning path to obtain the test signal accordingly. Then, the scanner device outputs the test signal for amplification. The amplified test signals are sent to an analog/digital converter such that the amplified test signals are converted into digital signals, which are then output to a computing unit for analyzing for subjective analytical results. The computing unit couples with the controller device, wherein the controller device controls a driver device that drives the scanner device to perform the scanning operation on the test paper.
