Patent ID: 8757496

Claim:
A biological sample measurement device comprising: a main body case having a sensor insertion port which is for inserting a biological sample measurement sensor having a colored section; a connector which is disposed in the main body case and which is configured to attach the biological sample measurement sensor; a light-emitting element which is disposed in the main body case and which is configured to apply light to the colored section of the biological sample measurement sensor attached to the connector; a light-receiving element which is disposed in the main body case and which is configured to receive the light reflected from the colored section of the biological sample measurement sensor attached to the connector, and output a color data of the received light; a connector terminal which is disposed in the main body case and can be connected to a connection terminal section of the biological sample measurement sensor attached to the connector; a determination section which is configured to determine a type of the biological sample measurement sensor attached to the connector based on the color data; and a measurement section which is configured to measure a substrate in the biological sample in the biological sample measurement sensor attached to the connector based on the determination result of the determination section.
