Abstract:
A liquid surface imaging device includes an irradiator including a plurality of lightings, the irradiator configured to irradiate a liquid surface in a nozzle of a liquid discharge head with lights emitted from the plurality of lightings, and an imaging device configured to image the liquid surface. The plurality of lightings is arranged point-asymmetrically with a center of the imaging device as a point of symmetry.
