[0036] 1.1 Outline of liquid ejection device

[0037] figure 1 It is a diagram showing a schematic configuration of the liquid ejection device 1 . The liquid ejection device 1 in this embodiment is an inkjet printer of the serial printing method as follows: , the liquid ejection head 22 ejects ink to the conveyed medium P to form a desired image on the medium P. In the following description, the direction in which the carriage 21 moves is referred to as the X direction, the direction in which the medium P is conveyed is referred to as the Y direction, and the direction in which the ink is ejected is referred to as the Z direction. Note that, although the X direction, the Y direction, and the Z direction are described as directions orthogonal to each other, they are not limited to the fact that the various configurations included in the liquid ejection device 1 are arranged orthogonally. Here, the direction in the X direction along which the carriage 21 on which the liquid e...

[0110] Next, a liquid ejection device 1 according to a second embodiment will be described. In the liquid ejection device 1 according to the first embodiment, the case where the ejection unit 600 has two piezoelectric elements 60 and ink is ejected from one nozzle N using the two piezoelectric elements 60 has been described. However, In the liquid ejection device 1 in the second embodiment, the ejection section 600 has four piezoelectric elements 60, and ink is ejected from one nozzle N using the four piezoelectric elements 60, which is different from that of the first embodiment in this point. The liquid ejection device in the method is different. It should be noted that, when describing the liquid ejection device 1 of the second embodiment, the same components as those of the first embodiment are given the same reference numerals, and the description thereof is simplified or omitted.

[0111] In the liquid ejection device 1 in the second embodiment, 2M connection channels R...

Abstract

The invention provides a liquid ejecting apparatus and an integrated circuit device, which can improve the transmission speed of signals. In a liquid ejecting apparatus, an integrated circuit that controls supply of a drive signal to a first drive element and a second drive element based on an ejection control signal includes: a first switching circuit that inputs the drive signal and switches whether or not to output the drive signal to the first drive element; a second switching circuit which inputs the driving signal and switches whether to output the driving signal to the second driving element; and a switching control circuit which inputs the ejection control signal and controls whether the first switching circuit and the second switching circuit output the driving signals respectively, the switching control circuit controlling the first switching circuit and the second switching circuit based on the first data.

Description

technical field [0001] The present invention relates to a liquid ejection device, and an integrated circuit device. Background technique [0002] In a liquid ejection device that ejects liquid to a medium, there is known a configuration in which the internal pressure of a cavity filled with liquid is changed by driving a drive element based on a drive signal, and the internal pressure is changed by the internal pressure. Changes in pressure to eject liquid. In addition, in a liquid ejection device that ejects a liquid by changing the internal pressure of the cavity by driving such a drive element, the liquid ejection device that ejects a high-viscosity liquid has a In the case of a liquid ejecting device having a function of circulating a liquid, etc., there is known a liquid ejecting device as follows: for the purpose of stable liquid ejection and stable liquid circulation, corresponding to the ejection liquid One nozzle has a plurality of driving elements, and is driven ...
