Abstract

PURPOSE:To facilitate removing/mounting of desired ink containers even if arranged at a small space, by providing knobs on a plurality thereof mounted exchangeably on the carriage in a zigzag way therebetween. CONSTITUTION:Knobs 15 are mounted on the surfaces of ink containers 4 in a zigzag way alternately between adjacent ones 4 when the surface comes outward as back side thereof. The ink containers 4 are inserted into dents 11 divided with partitions at the rear of a carriage 2 pinching a knob 15 from behind and can be taken out pinching the knob 15 with a finger.

Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to the structure of an inkjet recording device, and in particular,
The present invention relates to the structure of an inkjet recording device in which a plurality of ink containers are replaceably mounted on a carriage.

[Prior art]

An inkjet recording device guides ink in an ink container to a recording head, and ejects the ink toward a recording material (paper) by driving multiple nozzles provided in the recording head in accordance with a print nose turn signal to perform recording. It is used in printers, facsimile machines, etc. as output devices for electronic devices.

Compared to other methods such as wire dot methods and thermal transfer methods, this inkjet recording method produces less noise, is suitable for high-speed printing, and has the characteristics of being easy to print in color.

An inkjet recording apparatus for color printing usually uses ink of the three primary colors cyan, magenta, and yellow in addition to black, and is therefore equipped with four recording heads and four ink containers.

Furthermore, recent inkjet recording apparatuses have a structure in which an ink container is mounted along with a recording head on a carriage that moves along a recording material, thereby reducing the size and weight of the entire apparatus.

By the way, in an inkjet recording device for color printing in which ink containers (ink cartridges) are mounted replaceably on a carriage, a plurality of (ink cartridges) are stored in a narrow space on the carriage.
For example, four (4) ink containers are installed side by side, so it is necessary to use relatively narrow containers and arrange them at narrow intervals.

However, since the conventional structure uses an ink container without a handle, there is a problem in that it is very difficult to remove and install the ink container in a narrow space.

〔the purpose〕

The purpose of the present invention is to solve the problems of such conventional structures,
Even when arranging multiple ink containers in a narrow space,
It is an object of the present invention to provide an inkjet recording device in which a desired ink container can be easily removed and attached with a finger.

[Summary] The present invention achieves the above object by providing handles at positions such that a plurality of ink containers replaceably mounted on a carriage are arranged in a staggered manner.

〔Example〕

The present invention will be described in detail below with reference to FIGS. 1 to 3.

In FIGS. 1 to 3, recording material (paper) 11c? Four recording heads 3 and four ink containers (ink cartridges) 4 for supplying ink to each recording head are mounted on a carriage 2 that moves B.

The recording material 1 is fed while being supported by the platen 5, and the carriage 2 is guided by a pair of guide shafts 6.6 installed parallel to the platen 5 and moves.

The four recording heads 3 print in different colors, for example, black and the three primary colors (cyan, magenta, yellow), and therefore the four ink containers 4 corresponding to these print in these four colors. Filled with ink.

Each recording head 3 has a plurality of (for example, 24) nozzles 7 (
The drawing shows a chip with 24 nozzles formed thereon), and by driving these nozzles in response to print/master turn signals, ink is ejected from the desired nozzles, thereby forming desired characters and figures. are recorded on the recording material IK.

The nozzle 7 and the recording material 1 face each other with a gap of about 1s11, for example.

An ink supply tube 8 is connected between each ink container 4 and each recording head 3, and the nozzles are driven by a current applied to each recording head through a flexible circuit 9 and a common electrode 10. Examples of nozzle driving methods include a method using a piezo element and a method using a guzzle generated by heating.

Each of the ink containers 4 is installed replaceably.

That is, at the rear of the carriage 2, there are 4 partitions partitioned by a partition wall.
Two recesses 11 are formed, and ink containers 4 of predetermined colors can be inserted into these recesses from the rear, and then removed and replaced after the ink is consumed.

In the illustrated example, a hollow needle 12 to which the supply pipe 8 is connected is fixed to the inner surface of each recess 11, and when the ink container 4 is attached, the hollow needle 12 is inserted into the socket 13. An ink outlet is formed. In addition, an elastically deformable hook 1 is provided at the top of each recess 11.
4 is provided, and when the ink container is attached, it is hooked to the back side of the ink container to perform the function of positioning and preventing rattling.

A handle 15 is provided on the back surface of each ink container 4, that is, on the outer surface when installed. Furthermore, as shown in FIG. 2, the positions of the handles 15 are set at different levels between adjacent ink containers 4, and are arranged in a staggered manner.

Therefore, when one of the four color ink containers 4 is used up and replaced with a new one, the ink container can be taken out by pinching the handle 15 with one's fingers, and the new container 4 can also be taken out by pinching the handle 15. It can be inserted with .

According to the embodiment described above, a plurality of ink containers 4 are installed in a replaceable manner, and the handles 15 are provided in staggered positions for each container, so that a plurality of ink containers 4 can be installed in a narrow space on the carriage. Even when the ink containers 4 are mounted, each ink container 15 can be easily replaced because the finger can be easily inserted and the handle 15 can be pinched.

In addition, in the above embodiment, the case where four ink containers are inserted from the rear is illustrated, but the present invention is applicable regardless of the number of ink containers 4 and the insertion direction (i.e.,
Any number of ink containers (two or more) may be inserted in any direction, such as up and down, left and right, or diagonally.

〔effect〕

As is clear from the above description, according to the present invention, there is provided an inkjet recording device that allows each ink container to be easily removed and installed when a plurality of ink containers are mounted on a carriage so as to be replaceable. .
