Abstract

An ink jet recording apparatus having a tube pump for generating negative pressure in a tube, the tube pump being provided with a tube disposed along an arcuate guide portion, a pressing roller for squeezing the tube, a rotary member to which the pressing roller is rotatably journalled, and a supporting member to which the rotary member is rotatably journalled, wherein the tube, the pressing roller, the rotary member and the rotary member supporting member are assembled to thereby form a pump unit, and are separable from the guide portion in the state of the pump unit. Thereby, the incorporation of the tube becomes easy, and the erroneous incorporation of incorporating the tube in its buckled state or its twisted state can be eliminated easily.

Description

Technical field [0001] The present invention relates to a straight tube pump, a discharge recovery device using the straight tube pump, and an inkjet recording device having the discharge recovery device, wherein the straight tube pump is suitable for discharging ink from a recording mechanism to a recording material The suction mechanism of the discharge recovery device on the inkjet recording device that performs recording. Background technique [0002] In recent years, the use of inkjet recording devices has increased with the increase in utility value, and the use of inkjet recording devices has been expanding. The inkjet recording device characterized by high-quality photographs mainly uses black text to record. In order to emphasize the vividness of black, only black uses pigment ink, Inkjet recording devices in which inks of other colors are dyes, and inkjet recording devices characterized by low prices are also increasing. With the increase of models, the types of inkjet ...
