PROBLEM TO BE SOLVED: To provide a medical measuring device which has a simple structure and which allows recording paper to be easily taken in and out of a recorder. SOLUTION: When the opening/closing case 110 is in an open state, the end of the folding paper 1 accommodated in a recording paper accommodation unit 140 is lifted up in association with the rotation of a rotating shaft 103 of the opening/closing case 110, and the opening/closing case 110 is opened. Is provided in a closed state, the projection 104 as a lifting portion that lowers the end of the folded paper 1 accommodated in the recording paper accommodation unit 140 from the raised position is provided. It becomes easy to put the folding paper 1 in and out of the recorder 100. [Selection diagram] Figure 8【課題】簡易な構成でありながら、レコーダーへ記録紙を出し入れしやすい医療用測定装置を提供すること。【解決手段】開閉ケース110の回転軸103の回転に連動して、開閉ケース110が開状態のときに記録紙収容部140に収容されている折畳紙1の端部をせり上げ、開閉ケース110が閉状態のときに記録紙収容部140に収容されている折畳紙1の端部をせり上げ位置から下降させる、せり上げ部としての突起104を設けたことにより、簡易な構成でありながら、レコーダー100へ折畳紙1の出し入れがしやすくなる。【選択図】図8
