Abstract

The invention provides a buffer and liquid ejecting apparatus, which can maintain stable liquid supply for a liquid ejecting head. A buffer 53 receiving and supplying liquid includes: a cylindrical cup 53a having a bottom; and a flexible film 53b forming a sealed space S between the cup 53a and the film, wherein one of a depressed portion 53d and a projecting portion is formed at an open end 53c of the cup 53a, and wherein the film 53b is attached to the open end 53c and one of the depressed portion 53d and the projecting portion along the surface thereof.

Description

technical field [0001] The present invention relates to a buffer and a liquid ejection device. Background technique [0002] A conventionally known liquid ejecting device ejects a liquid such as ink from a liquid ejecting head, arranges liquid droplets on a recording medium, and records characters, images, and the like. [0003] In addition, as disclosed in Patent Document 1, a buffer is provided on the liquid ejecting device, which accommodates a predetermined amount of liquid in order to maintain a stable supply of the liquid to the liquid ejecting head. [0004] The bumper disclosed in Patent Document 1 is provided on the opposite side of the nozzle on the liquid ejection head. The buffer is a flexible film, and a hermetically sealed liquid chamber is formed between the film and the liquid ejection head. During normal operation, the liquid is sent from the main tank containing the liquid to the liquid chamber, and the liquid is filled into the liquid chamber, and the fi...
