ABSTRACT:
An apparatus for inspecting drawing accuracy in a liquid droplet ejection apparatus performs drawing by ejecting a function liquid droplet while moving a function liquid droplet ejection head relative to a workpiece by using a moving mechanism. In response to the relative movement, a laser irradiating mechanism performs visually recognizable stippling on the workpiece by irradiating coherent light thereon. A control part drives the laser irradiating mechanism for stippling at a predetermined frequency timing.
