Technical field

The utility model is related to printing device technical field more particularly to a kind of ink-jet printers.

Background technology

Ink-jet printer 1 is printed by spraying ink from record head to recording medium (such as paper sheet for printing).

Fig. 1 to Fig. 3 schematically shows an example of existing ink-jet printer.Hereinafter, for ease of description, with When user uses ink-jet printer on the basis of location, direction of the ink-jet printer towards user is defined as " preceding ", on the other hand direction are defined as " rear ", and the left-hand side of user is defined as " left side ", and the right-hand side of user is " right side ".

With reference to figure 1, ink-jet printer 1 includes that printer body 19 and the ink being arranged in the side of printer body 19 hold Receive unit 40.Printer body 19 can accommodate the components such as record head (not shown) in inside.

In addition, ink-jet printer 1 further includes turning part 30, turning part 30 can be provided with scanner in inside.It turns over Rotation member 30 is pivotably connected to printer body 19, in the opening for exposing printer body 19 and black housing unit 40 Between position P31 and override printer ontology 19 and the closed position P32 of black housing unit 40 pivotably.

As shown in Figures 2 and 3, black housing unit 40 is fixedly mounted in certain side of printer body 19 (for example, Fig. 1 Shown in lean on the forward position of right end), and accommodate to be supplied to the ink of printer body 19.

Black housing unit 40 includes the ink tank portion 20 at least one ink tank 24, corking portion 91 and covering ink tank portion 20 Top surface covering part 92.

Black housing unit 40 includes four ink tanks 24 for accommodating the ink with identical or different color, is set to the ink The top of tank 24 and the refilling portion 28 being connected to the inside of the ink tank 24.Ink tank portion 20 is for fixing four ink tanks 24 and making For its outer packaging.In addition, the side in ink tank portion 20 is provided with transmittance section 88, transmittance section 88 may make light can from side into Enter in ink tank 24, consequently facilitating from black housing unit 40 front from ink surplus.

Ink tank portion 20 is substantially in cube, and top surface is provided with around each refilling portion 28 and from the top in ink tank portion 20 Recessed portion towards lower recess.Refilling portion 28 is contained in recessed portion.

Corking portion 91 is for sealing each refilling portion 28.Corking portion 91 is as pivotally connected to ink around corking portion pivotal axis 99 Tank portion 20.Corking portion pivotal axis 99 limits corking portion pivot axis AX1.Each comfortable corresponding refilling portion of sealing of four corking portions 91 28 the first closed position P12 (Fig. 2) and expose corresponding refilling portion 28 the first open position P11 (Fig. 3) spaced winding corking Portion's pivotal axis 99 is pivotably connected to ink tank portion 20.

Specifically, corking portion 91 has the sealing 93 for sealing refilling portion 28.In addition, corking portion 91 passes through corking portion Pivotal axis 99 is pivotably connected with ink tank portion 20.In other words, corking portion pivotal axis 99 is fixedly provided in ink tank portion 20 Top, corking portion 91 are as pivotally connected to corking portion pivotal axis 99.

Covering part 92 is pivotably connected to ink tank portion 20 around covering part pivotal axis (not shown).Covering part pivots axis limit Covering part pivot axis AX2.Covering part 92 can be in the second closed position P22 (Fig. 1) and the second open position P21 (Fig. 2 and figure 3) it is pivoted relative to ink tank portion 20 between.When corking portion 91 is located at the first closed position P12, it is located at the second closed position P22 Covering part 92 can cover each corking portion 91, and as shown in figure 3, when covering part 92 is located at the second open position P21, position Each refilling portion 28 is set to expose in the corking portion 91 of the first open position P11.

Specifically, covering part pivotal axis is fixedly provided in the top in ink tank portion 20, such as by covering part bearing 96, covers Cap 92 is as pivotally connected to covering part pivotal axis.

When refilling, black bottle (not shown) can be stood upside down and be plugged in refilling portion 28.At this point, due to refilling portion 28 by every Film is divided into two parts, i.e. air duct and ink channel.It is replaced by gas-liquid, the ink in black bottle can pass through refilling portion 28 Ink channel automatically flows into ink tank 24, meanwhile, correspond ground, the air in ink tank 24 by air duct be automatically drained out to In black bottle, until the ink of injection ink tank 24 reaches maximum ink holding capacity.Gas-liquid displacement at this time stops, and refilling stops.

However, due to there is interval between corking portion pivotal axis 99 and covering part pivotal axis, black housing unit 40 exists Size in the front-back direction is larger, it is difficult to reduce the volume of black housing unit 40.

Therefore, it is necessary to a kind of ink-jet printer be proposed, to solve to ask more than existing in the prior art at least partly Topic.
