Abstract

Vibration is prevented from being transmitted via a fixed substrate (3). In order to differentiate the resonance frequency for the vibration of a piezoelectric vibrator (4), piezoelectric vibrators (4) having different lengths are fixed to the same fixed substrate (3). Even if residual vibration of a pressure generation chamber (9) which is expanded / contracted by a piezoelectric vibrator (4) to which a voltage is applied is transmitted to the fixed substrate (3), and the vibration is transmitted to a second piezoelectric vibrator (4) via the fixed substrate (3), the second piezoelectric vibrator (4) does not vibrate because the resonance frequency is different among the piezoelectric vibrators (4). Consequently, the pressure generation chamber (9) on which the second piezoelectric vibrator (4) is abutting is neither expanded nor contracted by the vibration.

Description

technical field [0001] The present invention relates to a printing head and a printing device that discharges a discharge liquid from a discharge hole and makes it land on a discharge object such as a substrate, and particularly relates to a printing head and a printing device used in the manufacture of liquid crystal or EL display elements, etc. . Background technique [0002] In recent years, inkjet type discharge devices have been used in the production of color filters for liquid crystal display devices and organic EL display devices. [0003] The reference numeral 101 in Fig. 4(a), (b) is a part of the printing head of such an ejection device, and the reference numeral A in Fig. 4(a) 0 is a rough front view of the internal structure, and the reference sign B in Fig. 4(b) 0 It is a schematic side view. [0004] A nozzle plate 106 is provided at a position below the casing 102 of the print head 101 , and a plurality of pressure generating chambers 109 are provided in t...
