PROBLEM TO BE SOLVED: To provide a water dispenser which can measure the amount of water without being affected by entering of air and regardless of the injected amount of water.SOLUTION: The water dispenser includes medicinal solution selectively injecting mechanisms 21-26 for holding various medicinal solution bottles 30 and selectively injecting optional one of the medicinal solutions therefrom into a dispensing bottle 20, and a control device 40 serving as a measuring means for calculating the injection amount by imaging the dispensing bottle 30 by an imaging device 36 and detecting a liquid surface 30a based on the image data 41. The water dispenser also includes a dispensing bottle elevating mechanism 31 for elevating the dispensing bottle 30 and an imaging device elevating mechanism 35 for elevating the imaging device 36. The elevating position is reflected directly or indirectly to the calculation of the injection amount.COPYRIGHT: (C)2011,JPO&INPIT【課題】空気の混入にも注入量の多寡にも煩わされずに計量しうる水剤分注機を実現。【解決手段】各種の液剤瓶30を保持していてその中から任意の液剤を選択して投薬瓶20に注入する薬液選択注入機構21~26と、投薬瓶30を撮像装置36で撮ってその画像データ41から液面30aを検出して注入量を算出する計量手段としての制御装置40とを備える。投薬瓶30を昇降させる投薬瓶昇降機構31と、撮像装置36を昇降させる撮像装置昇降機構35も設けて、昇降位置を直接か間接的に注入量算出に反映させる。【選択図】 図1
