COMPONENT MEASURING DEVICE

摘要

A component measuring device includes a calibration member that is slidably disposed in an insertion hole of a chip attachment unit and a biasing member that biases the calibration member toward an insertion port. The calibration member is held by the biasing member at a position where the calibration member blocks the introduction port and a lead-out port and where light from a light emitter is applied to the calibration member when a measuring chip is not inserted in the insertion hole, and slides to a side opposite to the insertion port along with insertion of the measuring chip into the insertion hole so that light from the light emitter is applied to the measuring chip.

1. A component measuring device that measures a predetermined component in a body fluid taken into a measuring chip, the component measuring device comprising:
a chip attachment unit including an insertion hole into which the measuring chip is inserted; a light emitter that applies light to the measuring chip through an introduction port open on a wall surface constituting the insertion hole; a light receiver that receives light from the measuring chip guided through a lead-out port open on the wall surface constituting the insertion hole; a calibration member slidably disposed in the insertion hole along an insertion direction of the measuring chip; and biasing member for biasing the calibration member toward an insertion port of the insertion hole, wherein the calibration member is held by the biasing member at a position where the calibration member blocks the introduction port and the lead-out port and where light from the light emitter is applied to the calibration member when the measuring chip is not inserted in the insertion hole, and slides to a side opposite to the insertion port along with insertion of the measuring chip into the insertion hole so that light from the light emitter is applied to the measuring chip.
