Abstract

Disclosed is an arrangement wherein light can be efficiently radiated to test papers even if a light source with a small amount of light is used, and wherein diameters of radiation spots projected onto test papers, as well as luminance distributions, can be adjusted. This arrangement is provided with an installation section (30) in which a tip (100) is installed, a light source (80a) which emits light having a specified wavelength, and a light receiving element (44) which receives light reflected from a test paper (107). Furthermore, the arrangement is provided with a condensing lens (53) which the moment that the light emitted by the light source comes in, concentrates the light on the test paper (107), and an optical path block (26). The optical path block (26) is equipped with an aperture section (66) which is located between the condensing lens (53) and the light source (80a) and which is installed at the position of the photographic subject for the condensing lens (53).

Description

technical field [0001] The present invention relates to a component measurement device for optically measuring blood glucose levels, urine components, or predetermined components in liquids such as waste water and industrial water. Background technique [0002] Conventionally, in order to detect chemical components in body fluids and industrial water, and to measure the amount and properties of specified components, component measuring devices that optically measure specified components have been used. The component measuring device first impregnates a test paper with liquid such as blood, and irradiates the test paper with light having a predetermined wavelength. Then, by measuring the intensity of reflected light reflected from the test paper, predetermined components in the measurement liquid are calculated and measured (for example, refer to Patent Document 1). [0003] In addition, Patent Document 2 describes a technique in which two light sources having different wave...
