摘要： A liquid ejecting head includes nozzles that eject a liquid, communication paths in which the respective nozzles are disposed and which are arrayed and partitioned from adjacent ones of communication paths by partition walls, pressure chambers which communicate with the respective communication paths and which are arrayed and partitioned from adjacent ones of pressure chambers by partition walls, pressure generating portions that are provided in the respective pressure chambers and that vary a pressure of the pressure chambers to cause the liquid to be ejected from the nozzles, and common flow paths through which at least one of supplying and discharging the liquid is performed to and from flow paths including the communication paths and the pressure chambers. A compliance of the partition walls of the communication paths is made larger than a compliance of the partition walls of the pressure chambers.

摘要： There is provided a flush box in an area other than a recording area in an end portion of a range in which a recording head can be driven in a main scanning direction. A control circuit performs control such that it is determined whether or not a flag is turned on for flushing operation in step S3; in a case where the flag is turned on, in step S4, it is determined whether final path is already finished or is about to be finished; when it is determined that the recording head is on the final path, in step S5, it is determined whether or not the stop position is on the side of the flush box. Then, maintenance operation is started in step S6 and paper feeding operation is executed in step S7 only when the stop position is on the side of the flush box. In addition, only the paper feeding operation is executed in step S7 when the stop position is on a side opposite to the side of the flush box.

摘要： A liquid discharge device includes a channel member, a nozzle plate, a flexible film, a support, and a lid. The channel member has a storage chamber that stores liquid. The nozzle plate has a nozzle through which the liquid stored in the storage chamber is discharged. The flexible film forms part of walling of the storage chamber. The support has an opening that surrounds a space where the flexible film is exposed at a side of the flexible film opposite the storage chamber. The lid is configured to cover the flexible film across the space, and is bonded, by an adhesive, to a surface of the support. The support has a groove provided in the surface bonded to the lid. The adhesive is also disposed in the groove.
