Embodiment Construction

[0025] Embodiments of the present invention will be described below with reference to the accompanying drawings. Such as figure 1 As shown, the color inkjet printer 100 includes four ink tanks 61 , a print head unit 63 , a carriage 64 , a driving unit 65 , a pressing roller 66 and a cleaning unit 67 . Each ink tank 61 is filled with ink of a specific color, such as blue, red, yellow or black. The print head unit 63 has an inkjet head 6 for performing a printing operation on the paper 62 . The ink tank 61 and the print head unit 63 are mounted on a carriage 64 . The drive unit 65 linearly reciprocates the carriage 64 . The pressure roller 66 extends in the carriage reciprocating direction and faces the inkjet head 6 .

[0026] The driving unit 65 includes a carriage shaft 71 , a guide plate 72 , two pulleys 73 , 74 and an endless belt 75 . The carriage shaft 71 is provided at the lower end of the carriage 64 and extends in a direction parallel to the pressing roller 66 . ...

Abstract

In an ink-jet printer, a support member includes a wiper cleaning zone provided upstream of a wiping direction of a nozzle surface. The wiper cleaning zone includes a cleaning wall, a first surface, and a plurality of grooves. The cleaning wall protrudes from the support member. The first surface extends in a direction reverse to the wiping direction, continuously from the cleaning wall. The plurality of grooves are provided in the first surface, extending from the cleaning wall. The grooves are formed at a predetermined distance from each other and hold ink therein by capillary action. Ink, adhered to a wiper by wiping operation, is rubbed by the cleaning wall provided in the wiper cleaning zone, and the collected ink is held by the grooves continuously formed from the cleaning wall. A similar, but reversed, structure is found on the other side of the nozzle surface in the wiping direction.

Description

technical field [0001] The present invention relates to an inkjet recording device, and more particularly to an inkjet recording device in which ink adhering to a wiper can be surely wiped off with a simple structure and can be prevented from being removed from the wiper. The ink collected on the screen drips and scatter. Background technique [0002] An inkjet recording device is an image forming device that ejects ink droplets through a plurality of nozzles provided in an inkjet head to form an image on a recording medium such as recording paper and a general transparent film. In an inkjet recording apparatus, when ink is ejected or when deteriorated ink is purged out of the nozzle, ink may adhere to the nozzle surface. If ink droplets are ejected from the nozzles to form an image with such ink attached to the nozzle surface, the ink droplets may be ejected in a wrong direction. This may cause printing to fail. Ink adhering to the nozzle surface may stain the recording ...
