First Claim
1. A portable, scanning and analyzing apparatus, used to scan a test paper and the test paper comprises a test sample thereon, the scanning and analyzing apparatus comprising:
- a scanner device, for scanning the test paper and outputting a test signal corresponding to the test sample, wherein the scanner device comprises an integrated modular scanning probe comprising at least a light emitting diode (LED) array light source and at least a photodiode detector array assembled together in the integrated modular scanning probe, wherein the LED array light source emits a light to the test paper and the test paper reflects the light to the photodiode detector array, wherein the light from the LED array light source is incident to a surface of the test paper by an incident angle of 45 degrees from a normal direction of the surface of the test pate and the test paper reflects the incident light by deflecting 90 degrees from the incident angle;
a computing unit, coupled to the scanner device to receive and analyze the test signal, wherein the computing unit receives an incoming command and accordingly outputs a control signal;
a controller, coupled to the computing unit, wherein the controller outputs a driver signal in accordance with the control signal received; and
a driver device, coupled with the controller device and the scanner device, wherein the driver device receives the control signal and accordingly drives the scanner device to scan the test paper.

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.
