摘要： According to one embodiment, a liquid dispensing apparatus includes a mounting unit configured to hold a liquid discharging apparatus that discharges liquid from nozzles simultaneously by an operation of an actuator. An inspection media placement region is provided on which an inspection medium can be placed to receive the liquid discharged from the liquid discharging apparatus. A controller is configured to control the actuator to vary a volume of the liquid discharged from each nozzle for a nozzle inspection operation. The volume is varied according to a predetermined distance between adjacent nozzles that simultaneously discharge liquid and a predetermined contact angle for a droplet of the liquid when on the inspection medium.
