Abstract: A liquid ejecting head includes: a first-flow-path-member having a first-surface in which a first-opening is formed; a second-flow-path-member having a second-surface in which a second-opening is formed; and a filter member disposed between the first-surface and the second-surface, in which the second-opening is larger than the first-opening in plan view, the filter member has a first-region in which first holes are provided, and a second-region positioned around the first-region and in which second holes are provided in plan view, the first-region includes a filter region which partitions off the first-opening and the second-opening and through which liquid passes, the second-region is in contact with both the first-surface and the second-surface, and includes a first-fixed-region to which an adhesive adheres, and an area of each of the second-holes is larger than an area of each of the first-holes in plan view.

Abstract: A printer reduces the amount of ink wastefully consumed by purging bubbles from the ink supply path. The printer has a bubble collection unit 35 that holds bubbles in the ink supply path 21 and has at least two ink paths, a first channel 26 and second channel 27, formed in the ink supply path 21 through which ink flows to the nozzles that eject ink droplets. A bubble detection unit 37 detects if the amount of bubbles in the bubble collection unit 35 has reached a specific level. A bubble discharge unit 41 discharges bubbles from the bubble collection unit 35 based on the detection result from the bubble detection unit 37. When the bubble detection unit 37 discharge bubbles from the bubble collection unit 35, ink flows through both the first path and the second path. When printing on a print medium, ink only flows through the first path.

Abstract: An inkjet printer has a nozzle cap that keeps the nozzle surface of the inkjet head moisturized, and can keep the nozzle cap moist by means of a simple mechanism. A check processing device incorporating the inkjet printer has an inkjet head, a nozzle cap that covers the nozzle surface of the inkjet head and keeps the nozzle surface moist, and a shutter that closes the open part of the nozzle cap to keep the inside of the nozzle cap moist. When the nozzle surface of the inkjet head is not capped, a moisture retention state in which moisture inside the nozzle cap is prevented from evaporating can be held by the shutter covering the open part of the nozzle cap.
