Zusammenfassung: | PROBLEM TO BE SOLVED: To provide a liquid type specifying apparatus which accurately specifies the type of liquid while suppressing an increase in processing burden.SOLUTION: A liquid type specifying apparatus 10 includes a propagating body 20 provided in a container 70 that stores liquid 80 to propagate vibrations, a vibration generating unit 32 provided at one end portion 25 of two end portions of the propagating body 20 to vibrate the propagating body 20, a vibration detecting unit 33 provided at the end portion 25 where the vibration generating unit 32 of the propagating body 20 is provided to detect vibration of the propagating body 20, and a type specifying unit 51 for specifying the type of the liquid 80. The propagating body 20 propagates a surface wave Ws of which vibration propagates on the surface of the propagating body 20 and has a surface wave reflecting portion 24 which reflects the surface wave Ws. The type specifying unit 51 specifies the type of the liquid 80 based on a surface wave propagation period T2 from the occurrence of vibration to the period when the surface wave Ws is reflected by the surface wave reflecting portion 24 and input to the vibration detecting unit 33.SELECTED DRAWING: Figure 1
【課題】処理負担の増加を抑制しつつ、液体の種類を正確に特定する液体種類特定装置を提供することにある。【解決手段】液体種類特定装置10は、液体80を貯留する容器70に設けられて振動を伝搬する伝搬体20と、伝搬体20の2つの端部のうちの一方の端部25に設けられて伝搬体20に振動を与える振動発生部32と、伝搬体20の振動発生部32が設けられる端部25に設けられて伝搬体20の振動を検出する振動検出部33と、液体80の種類を特定する種類特定部51と、を備える。伝搬体20は、振動が伝搬体20の表面を伝搬する表面波Wsを伝搬し、表面波Wsを反射する表面波反射部24を有する。種類特定部51は、振動が発生してから表面波Wsが表面波反射部24で反射されて振動検出部33に入力するまでの期間である表面波伝搬期間T2に基づいて液体80の種類を特定する。【選択図】図1 |
