Liquid-Discharge-Failure Detecting Apparatus and Inkjet Recording Apparatus

摘要

A light-emitting element (14) emits a beam onto a droplet discharged from a nozzle (nN) from a direction opposite to a direction of discharge of the droplet. A light-receiving element (17) receives a scattered light generated by scattering of the beam by the droplet. Finally, a failure detecting unit detects a liquid discharge failure of the nozzle (nN) from data of the scattered light received by the light-receiving element (17).
