PROBLEM TO BE SOLVED: To provide an electrostatic type discharge device which has a photographing device capable of measuring a discharge time and a speed of electrostatically discharged ink and can discharge the ink in a predetermined direction for the measurement. SOLUTION: In the discharge device 10 for applying a test voltage between a nozzle electrode 23 in a nozzle container 22 storing the ink and a land electrode 27 disposed so as to face the nozzle container 22 to discharge the ink from the opening 24 of the nozzle container 22, the photographing device 40 photographs the discharged ink a plurality of times using a start of applying the test voltage as a photographing start signal and is structured so as to calculate a discharge time and the like from a photographing result. A projection 27a is provided on the upward surface of the land electrode 27, and the discharged ink lands on the projection 27a. COPYRIGHT: (C)2011,JPO&INPIT |
