Embodiment Construction

[0030] Reference is now made to the figure 1 - Figure 7 gives a description of the invention and details of the disadvantages of the related art. First, refer to Figure 1-Figure 3 A first embodiment of the droplet discharge head of the present invention will be discussed. figure 1 is a perspective view of the outside of the droplet discharge head. figure 2 is an exploded perspective view of the droplet discharge head. image 3 is a sectional view of the droplet discharge head.

[0031] The liquid drop discharge head has: a nozzle 1 for discharging liquid droplets; a pressure chamber 2 connected to the nozzle 1; a vibrating plate 3 (not shown) forming a side part of the pressure chamber 2; a piezoelectric element 4, the pressure chamber 2 The electrical element 4 can serve as an actuator device, such as a pressure generating device or a drive device that compresses the liquid in the pressure chamber 2 via the vibrating plate 3 . The droplet discharge head also has a comm...

Abstract

A liquid drop discharge head includes nozzles that discharge liquid droplets using piezoelectric elements. There is no lead component in the piezoelectric element.

Description

technical field [0001] The present invention relates to a liquid drop discharge head, a liquid drop discharge device, and an image forming device. Background technique [0002] As an image forming apparatus, an inkjet recording apparatus having a droplet discharge device including a droplet discharge head is known, such as a printer, a facsimile, a copier and a printer, facsimile, copier multifunction device. [0003] In an inkjet recording apparatus, droplets of a recording liquid are ejected from a recording head onto a recording medium such as paper, OHP (Overhead Projector) film, recording medium, or recording paper, thereby enabling imaging such as recording, printing, or reproduction. It is possible to record a high-precision image at high speed on a recording medium by an inkjet recording device. In addition, the running cost is cheap and the noise is small in the inkjet recording apparatus. Furthermore, in an inkjet recording device, a color image can be easily rec...
