PROBLEM TO BE SOLVED: To solve the problem that since a mechanism for ejecting a test piece is provided in a usual body fluid component measuring device, an eject lever or a coil spring is necessary, which uneconomically increases the number of part items or assembling manhours.SOLUTION: A body fluid component measuring device 1 is provided with a test piece attaching part 17 to which the test piece 30 for measuring a body fluid component is attached. The device 1 includes a grip piece 22 which is provided as a part of a casing 2 and can grip the test piece 30 forming a part of the test piece attaching part 17 and a supporting point part 45 which is provided in a part of the casing opposed to the grip piece 22 and abuts on the grip piece 22. The grip piece 22 has an input part 23 which is provided nearer to a base end side than to the supporting point part 45 and has flexibility. The input part 23 is pressed to rotate the grip piece 22 with the supporting point part 45 as a center to release the grip of the test piece 30.COPYRIGHT: (C)2012,JPO&INPIT【課題】従来の体液成分測定装置においては、試験片を排出するための機構を設けるために、イジェクトレバーやコイルばね等の部品が必要となり、部品点数及び組立工数が増えて不経済であった。【解決手段】体液成分を測定するための試験片30が装着される試験片装着部17を備えた体液成分測定装置1において、筐体2の一部として設けられ、かつ、試験片装着部17の一部を構成する、試験片30を把持可能な把持片22と、把持片22と対向する筐体の部分に設けられ、把持片22に当接する支点部45とを有し、更に、把持片22は、支点部45より基端側に設けられた可撓性を有する入力部23を備え、入力部23を押圧することにより支点部45を中心として把持片22を回動させて試験片30の把持を解除するようにした。【選択図】図1
