    Abstract: A droplet dispensing apparatus includes a droplet ejection device, a microplate holder, a sheet stand, an image capturing device and a controller. The image capturing device is configured to move to a position above the sheet stand. The controller is configured to perform image processing on image data generated from an image captured by the image capturing device when the image capturing device is at the position above the test sheet on the sheet stand, to determine a size of each of test patterns formed by droplets dropped on the test sheet from the array of nozzles. The controller is further configured to generate a data file including the determined size of each of the test patterns. The test sheet colors or discolors at a place receiving a light-transmissive droplet.

    Abstract: An ink jet head according to an embodiment comprises a substrate including amounting surface and a pressure chamber open to the mounting surface, the substrate having a first expansion coefficient. The ink jet head further comprises a vibration plate including a first surface fixed to the mounting surface of the substrate, a second surface located on the opposite side of the first surface, an opening portion open to the pressure chamber, a first portion having a second expansion coefficient different from the first expansion coefficient, and a second portion having a third expansion coefficient different from the second expansion coefficient. The ink jet head further comprises a piezoelectric element provided on the second surface of the vibration plate and configured to deform the vibration plate to thereby change a volume of the pressure chamber.
