Embodiment 1

[0118] Hereinafter, the present invention will be described more specifically with reference to waste ink storage units of preferred embodiments and comparative examples of the present invention. The following examples of the present invention are not intended to limit the scope of the present invention as long as they do not exceed the gist of the present invention. In addition, unless otherwise specified, the unit of the amount of each component used to describe the inks of the preferred examples and the comparative examples is "parts by mass".

[0120] (Preparation of black ink or solution containing black pigment)

[0121] A solvent prepared by dissolving 5 g of concentrated hydrochloric acid in 5.5 g of water was cooled to 5°C. Then, 4.65 g of p-aminobenzoic acid was added to the solvent while keeping the temperature of the solvent at 5°C. Next, the container containing the solvent was placed in an ice-bath, and the temperature of the solution was kept not hi...

Embodiment 2

[0144] refer to Figure 11 , the waste ink absorbing unit of the present embodiment is constituted by simply stacking three parallelepiped waste ink absorbing portions and an evaporation suppressing member disposed above the upper waste ink absorbing portion, and between the evaporation suppressing member and the upper waste ink absorbing portion A space with a height of about 1 mm is provided. The evaporation suppression member has two walls. The size of the portion of the evaporation suppressing member covering the upper surface of the upper ink absorbing portion was 80% of the size of the upper surface of the upper ink absorbing portion for absorbing pigment-based black waste ink.

Embodiment 3

[0146] refer to figure 2 , the waste ink absorbing unit of the present embodiment is constituted by simply stacking three parallelepiped waste ink absorbing portions and an evaporation suppressing member disposed above the upper waste ink absorbing portion, and between the evaporation suppressing member and the upper waste ink absorbing portion A space with a height of about 1 mm is provided. The evaporation suppression member has four walls. The size of the portion of the evaporation suppressing member covering the upper surface of the upper ink absorbing portion was 80% of the size of the upper surface of the upper ink absorbing portion for absorbing pigment-based black waste ink.

Abstract

The invention relates to an ink recording device, a residual ink container comprising laminated members for absorbing residual ink not used for recording, wherein the laminated members are laminated with a gap between adjacent ones of the members; and a covering member covering such that non-contact portion is provided between the covering member and a topmost one of the laminated member so as not to press against the topmost one.

Description

technical field [0001] The present invention relates to an inkjet recording apparatus provided with a substantially parallelepiped sheet-shaped waste ink absorbing member. The invention also relates to a waste ink storage unit having significantly higher ink absorption properties and ink storage capacity and thus a significantly longer service life than waste ink storage units according to the prior art. Background technique [0002] An inkjet recording apparatus is a recording apparatus that forms an image on a recording medium sheet such as plain paper, glossy paper, and dedicated coated paper by ejecting small ink droplets so that the small ink droplets land on the recording medium sheet. In recent years, the price of inkjet recording apparatuses has been remarkably reduced, and the printing speed thereof has also been remarkably increased. Thus, the use of inkjet recording apparatuses has rapidly spread to various fields. In addition, inkjet recording apparatuses have ...
