Problems solved by technology

[0009] However, although the movement of the ink supply hose in the above-mentioned printer is restricted by fixing its one end to the stationary part, its movement is not restricted on the side of the carriage which is the other end, so there may be a possibility of Phenomenon where the ink supply hose vibrates due to the reciprocating movement of the carriage
Therefore, there is a possibility that the quality of the image formed on the recording medium may be degraded due to the vibration of the ink supply hose being transmitted to the carriage and the recording head.

Abstract

A liquid ejection device includes a primary guide shaft extending along a primary scanning direction, a carriage supported on the primary guide shaft so as to be movable in the primary scanning direction, a liquid ejection head mounted on the carriage, a liquid supply tube connected at one end to a liquid storage member and connected at the other end to the liquid ejection head, and a contact member contacting a curved portion of the liquid supply tube extending from the carriage to form a curved shape. The contact member bears reactive force directed at the primary guide shaft in the conveying direction of the recording medium throughout the scanning range of the carriage from the liquid supply tube.

Description

technical field [0001] The present invention relates to a liquid ejection device. Background technique [0002] Conventionally, an inkjet printer (hereinafter also simply referred to as a "printer") is known as one type of liquid ejecting apparatus. This printer has a recording head (liquid ejection head) that ejects ink (liquid) from nozzles formed on a nozzle forming surface on a carriage. Also, an image is formed on the recording medium by ejecting ink from the recording head while the carriage is guided by the guide shaft intersecting with the conveying direction of the recording medium while reciprocating in the main scanning direction. extending in the main scanning direction. [0003] In addition, among such printers, there are so-called printers of the head-water separation type. In such printers of the head-water separation type, the ink cartridge (liquid ink tank) installed on the main body side of the printer in a manner independent of the carriage container) a...
