PROBLEM TO BE SOLVED: To simply judge whether the dispensing element in a liquid dispensing apparatus is operated. SOLUTION: A microphone 2 is arranged at a position capable of collecting the operation sound from the dispensing element 4 arranged in the housing 1 of the liquid dispensing apparatus. A speaker 8 is connected to the microphone 2 through a sound amplifier 6. By this constitution, the normal operation of the dispensing element can easily be judged on the basis of the sound data from the dispensing element in the liquid dispensing apparatus. Accordingly, for example, since dispensing operation can be judged by hearing sense even in a state that the user of the liquid dispensing apparatus receives the pressure on the processing of various data on a control screen in the case of using visual sensation, this apparatus is favorable.
