Patent ID: 8777347

Claim:
A liquid discharging apparatus comprising: a grounding line; a first discharger configured to discharge, by driving of a first drive element, a liquid in a first cavity through a first nozzle communicating with the first cavity; a first grounding terminal connecting the first drive element to the grounding line; a second discharger configured to discharge, by driving of a second drive element, a liquid in a second cavity through a second nozzle communicating with the second cavity; a second grounding terminal connecting the second drive element to the grounding line; a shared circuit selectively connectable to the first drive element and the second drive element via respective analog switches; a drive control unit configured to control the driving of each of the first drive element and the second drive element via the shared circuit; a switch unit configured to electrically disconnect the first grounding terminal from the second grounding terminal and the grounding line; a detector configured to detect an electric signal from the first drive element via the first grounding terminal when the first grounding terminal is electrically disconnected from the second grounding terminal and the grounding line, the detector being arranged to be electrically connected to the first ground terminal and to the second ground terminal; and an inspector unit configured to inspect the first discharger based on the electric signal, the switch unit having a first switch, a second switch, and a third switch, the first switch disposed between the first grounding terminal and the grounding line, the second switch disposed between the second grounding terminal and the grounding line, the third switch being disposed between the first grounding terminal and the detector, and between the second grounding terminal and the detector, the detector detecting the electric signal from the first drive element via the first grounding terminal while the first switch disconnects the first grounding terminal from the grounding line, the second switch disconnects the second grounding terminal from the grounding line, the third switch connects the first grounding terminal and the detector, and the third switch disconnects the second grounding terminal from the detector.
