Embodiment approach

[0055]

[0056] The printer 1 common to each embodiment will be described.

[0057] figure 1 It is a schematic configuration diagram of the printer according to the embodiment.

[0058] like figure 1 As shown, the printer (liquid jet recording apparatus) 1 of the present embodiment includes a pair of conveying mechanisms 2 and 3 , an ink tank 4 , an ink jet head (liquid jet head) 5 , an ink circulation mechanism 6 , and a scanning mechanism 7 .

[0059] In the following description, it is necessary to use the X, Y, and Z orthogonal coordinate system for the description. In this case, the X direction (second direction) matches the conveyance direction (sub-scanning direction) of the recording medium P (eg, paper, etc.). The Y direction (first direction) corresponds to the scanning direction (main scanning direction) of the scanning mechanism 7 . The Z direction (third direction) shows the height direction (vertical direction) orthogonal to the X direction and the Y direct...

[0070] The head chip 50 of the first embodiment will be described.

[0071] image 3 It is the perspective view which looked at the head chip of 1st Embodiment from -Z side in the state which removed the nozzle plate. Figure 4 It is an exploded perspective view of the head chip of the first embodiment.

[0072] image 3 and Figure 4 The illustrated head chip 50 is a so-called circulating side shooter that circulates ink between the ink tank 4 and the ink tank 4 and discharges the ink from a central portion in the extension direction (Y direction) of the discharge passage 75 to be described later. type head chip. The head chip 50 includes: a nozzle plate (ejection orifice plate) 51 (see Figure 4 ); the intermediate plate 52; the actuator plate 53; and the cover plate 54. The head chip 50 has a structure in which a nozzle plate 51 , an intermediate plate 52 , an actuator plate 53 , and a cover plate 54 are stacked in this order in the Z direction. In the fol...

[0138] The head chip 50 of the second embodiment will be described.

[0139] Figure 13 It is a bottom view of the actuator board of 2nd Embodiment.

[0140] like Figure 13 As shown, the present embodiment is different from the first embodiment in that the through-hole 250 is provided over the entire length of the Y-direction between the respective through-portions 75b of the pair of discharge passages 75 adjacent to the through-hole 250 in the X-direction. The through hole 250 protrudes outward in the Y direction from both ends of the respective through portions 75b of the pair of discharge passages 75 sandwiching the through hole 250 in a plan view. In other words, the through holes 250 are arranged from one outer side to the other outer side in the Y direction than the respective through portions 75 b of the pair of discharge passages 75 . The through-hole 250 is provided on the inner side in the X direction of the inner surface 76c of the non-discharge passa...

Abstract

Provided is a head chip that suppresses a decrease in printing quality. A head chip (50) is provided with: an actuator plate (53) in which discharge channels (75) and non-discharge channels (76) extending in the Y direction are alternately arranged in the X direction; an intermediate plate (52) which overlaps the actuator plate (53) in the Z direction and in which a communication hole (130) communicating with the discharge passage (75) and a through hole (150) communicating with the non-discharge passage (76) are formed; and a nozzle plate (51) which overlaps in the Z direction with respect to the intermediate plate (52) in a state in which the through-hole (150) is blocked, and in which a nozzle hole (145) which communicates with the communication hole (130) and ejects the liquid contained in the discharge channel (75) is formed at a position corresponding to the discharge channel (75). The non-discharge passage (76) communicates with the outside. The through-hole (150) is provided further toward the inside in the X direction than an inner surface (76c) of the non-discharge passage (76) extending in the Y direction when viewed from the Z direction.

Description

technical field [0001] The present disclosure relates to a head chip, a liquid jet head, a liquid jet recording apparatus, and a method of manufacturing the head chip. Background technique [0002] The ink jet head mounted on the ink jet printer discharges ink to the recording medium through the head chip mounted on the ink jet head. The head chip includes: an actuator plate in which discharge passages and non-discharge passages are alternately formed; and a nozzle plate that is joined to the actuator plate and formed at positions corresponding to the discharge passages to eject ink accommodated in the discharge passages nozzle hole. [0003] In recent years, the channels have been gradually narrowed, and the allowable range of positional displacement of the actuator plate and the nozzle plate has become smaller. Specifically, if the position of the nozzle plate relative to the actuator plate is shifted in the width direction of the channel, a part of the opening on the ch...
