Abstract

An apparatus of reading identification information according to a code attached on a biosensor. In reading the identification information through a pattern of the existing biosensor, a photodetector and a light resource are required for each segment so as to read segments of each pattern. However, such a system may cause a complexity of circuit-driving, raise manufacturing costs, and prolong operating hours. Thus, to solve these problems, provided is a technology, which, in contrast to the existing technology, has advantages of using a small amount of electronic components and reduced driving circuits to shorten working hours, and the like.

Claims

1. An apparatus of reading identification information of a biosensor, the apparatus comprising:

a light receiver;

a plurality of light emitters, which are located corresponding to and facing a plurality of segments on a surface of the biosensor, and which are arranged around the light receiver;

an identification code reader configured to sequentially turn on/off the plurality of light emitters according to each position thereof, and read the light receiver to read color information recorded on the segment which corresponds to and faces a position of the light emitter which has been turned on.

2. The apparatus of claim 1, wherein the light receiver comprises a plurality of photodetectors, which are connected in series or in parallel to each other, and which are capable of being simultaneously operated in entirety thereof by the identification code reader.

3. The apparatus of claim 1, wherein the plurality of light emitters comprise a plurality of light emitting elements, which are simultaneously operated by the identification code reader.

4. The apparatus of claim 3, wherein the identification code reader is configured to turn on/off the plurality of light emitters by alternating between horizontal and vertical directions.

5. The apparatus of claim 1, comprising:

a plurality of sets of reader modules including the light receiver, the plurality of light emitters, and the identification code reader.

6. The apparatus of claim 3, wherein the identification code reader comprises:

a light emitter driver connected to each of the plurality of light emitters;

a light receiver driver configured to drive the light receiver;

a converter configured to convert an output of the light receiver into a digital format; and

a pattern reader configured to read a pattern of an identification information code of the biosensor from an output of the converter.

7. A method for reading identification information of a biosensor, wherein the identification information is recorded according to an arrangement of different colors on a plurality of segments on a surface of the biosensor, the method comprising:

a) detecting an insertion of the biosensor;

b) turning on one of a plurality of light emitters arranged in a position corresponding to and facing segments on the surface of the biosensor which has been inserted while turning off the rest;

c) detecting a light, which has been projected from the light emitter and reflected from or penetrated through the biosensor;

d) reading, through the detected light, a code recorded in a position corresponding to the plurality of segments on the surface of the biosensor which has been inserted; and

e) reading identification information by repeating operations b) to d) with respect to the plurality of light emitters located in different positions, and by reading the codes of all the segments.

8. The method of claim 7, wherein the operation e) comprises turning on/off the plurality of light emitters by alternating between horizontal and vertical directions.
