[0047] figure 1 is a schematic longitudinal sectional view of the liquid jet head 1 according to the first embodiment, figure 2 Displays the position of the parting line of flow path part 2, image 3 It is a perspective view and an exploded perspective view when viewing the flow path member 2 used in the first embodiment from obliquely above, Figure 4 It is an exploded perspective view of the flow path member 2 used in the first embodiment viewed obliquely from below.
[0048] Such as figure 1 As shown, the liquid jet head 1 includes a flow path member 2 and an actuator 3 bonded to the flow path member 2 with an adhesive 13 . The flow path member 2 includes a first member 4 and a second member 5 joined to the first member 4 . The first member 4 and the second member 5 form a flow path 8 and a discharge port 12 therebetween.
[0049] The first member 4 has a supply port 11 for liquid supply and a supply connection portion 14 connected to the supply port 11 on its upper...

[0062] Figure 7 with Figure 8 It is a figure for demonstrating the manufacturing method of the liquid jet head which concerns on the 2nd Embodiment of this invention. Figure 7 It is a figure for explaining the 1st press molding process S1, (a) is an exploded view of a die, (b) is an assembly view of a die, and both show the vertical cross-section in the transverse direction. A gap is formed between the first die 31 , the second die 32 , and the third die 33 , and the synthetic resin is filled into the gap to mold the first member 4 . The cross section in the lateral direction of the first member 4 has a U-shape. The first metal mold 31 on the upper side has a first lower end surface B1 at the lower part of the left end, a third lower end surface B3 at the lower part of the right end, and a second lower end surface B2 at the center that is recessed upward from the periphery. recessed part. The third metal mold 33 on the lower side has a first depression K1 near the left ...

[0078] Figure 12 It is a schematic perspective view of a liquid ejecting device 50 according to a third embodiment of the present invention. The liquid ejecting device 50 uses the liquid ejecting head 1 described in the above-mentioned first or second embodiment. The liquid ejecting device 50 includes a moving mechanism 63 for reciprocating the liquid ejecting heads 1, 1', liquid supply pipes 53, 53' for supplying liquid to the liquid ejecting heads 1, 1', and liquid supply pipes 53, 53 for supplying liquid to the liquid ejecting heads 1, 1'. 'The liquid tank 51, 51'. Each liquid ejection head 1, 1' includes an actuator 3 for discharging liquid, a channel member 2 for supplying the liquid to the actuator 3, and a pressure buffer (not shown) for supplying the liquid to the channel member 2. .
[0079] Be specific. The liquid ejecting device 50 includes a pair of conveying devices 61 and 62 for conveying a recording medium 54 such as paper in the main scanning direction, a ...
