FIG. 1 is an external perspective explanatory view of an example of a printing device as a device for discharging a liquid according to the same embodiment, FIG. 2 is a front explanatory view, and FIG. 3 is a side explanatory view.

The printing device 1 is a printing means for printing on a supporting means 300 that supports the cloth 400 (FIG. 2) that is the object to be granted (printing target) and a cloth 400 that is supported and moved by the supporting means 300 in the device main body 10. It has 100 and.

The printing means 100 includes one or a plurality of heads 101 for discharging liquid, and a carriage 102 on which the heads 101 are mounted. The carriage 102 is guided by a guide member 103, which is a guide member, so as to be reciprocally movable in the main scanning direction (X direction).

The support means 300 includes a stage 301 on which the fabric 400 is placed and a slider 302 that supports the stage 301. The space between the slider 302 and the stage 301 is covered with an upper stage cover 303, a lower stage cover 304, and a slider cover 305.

The slider 302 of the support means 300 is movably supported by the guide member 307 via a bearing 306 in the sub-scanning direction (Y direction). The sub-scanning direction (Y direction) is the transport direction of the grant target supported by the support means 300. The support means 300 is also a transport means for transporting the fabric 400 to be granted.

Then, in the support means 300, a sealing member 501, which is a cap of the maintenance means 500, is arranged below the stage 301. In this case, the sealing member 501 of the maintenance means 500 is arranged in the region of the support means 300 in a plan view of the surface supporting the object to be provided by the support means 300 from the direction of arrow A in FIG. 2A. Just do it.

The maintenance means 500 has a plurality of sealing members 501 that seal (capture) the nozzle surface (discharge surface) 101a of each head 101. The plurality of sealing members 501 are supported by the sealing member holder 502 that moves up and down, and move back and forth with respect to the nozzle surface 101a. In addition to the sealing member 501, the maintenance means 500 can also include a wiping member for wiping the nozzle surface 101a.

The stage 301 is provided with an opening 310 that opens above the sealing member 501 of the maintenance means 500. In the present embodiment, the opening 310 is an opening through which the sealing member holder 502 of the maintenance means 500 can pass.

Further, at both ends in the main scanning direction, empty discharge receivers 520 that receive the liquid that is discharged from the head 101 and is not applied to the application target are arranged.

In the present embodiment, when the nozzle surface 101a of the head 101 is sealed by the sealing member 501, for example, the support means 300 at the positions shown in FIGS. 2 (a) and 3 (a) is subjected to the sub-scanning direction (Y direction). Move in the Y1 direction with.
