Patent ID: 8206649

Claim:
A component measuring apparatus for measuring a quantity and/or quality of a predetermined component in a specimen, comprising: a case including a tubular case body having a distal-end opening and a window formed in a side surface of the tubular case body; a detector for detecting the predetermined component, the detector being disposed in the distal-end opening of the case body and having at least a portion positioned inside the case body and a remaining portion projecting from the case body through the distal-end opening; a sampling device mounting part disposed on a distal-end portion of the detector and projecting outwardly from the detector for detachably mounting thereon a sampling device for sampling the specimen; a controller electrically connected to the detector to control operation of the detector, the controller being positioned in the tubular case body and including a measuring unit for measuring the predetermined component; a display operable to display a measurement result measured by the measuring unit, the display being positioned corresponding to the window to allow the measurement result displayed on the display to be visually observed through the window; a cell provided in the tubular case body for supplying electric power to at least the controller; hermetic sealing means disposed in the distal-end opening between the case and the detector for hermetically sealing; and an ejector member for removing the sampling device mounted on the sampling device mounting part from the sampling device mounting part, the ejector member being disposed outside of the detector and supported movably along axial directions of the case body.
