Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a printing apparatus, and more particularly, to a printing apparatus using a replaceable print head and a replaceable ink tank.

[0002]

2. Description of the Related Art In recent years, there has been a strong demand for color printing, and a color ink jet printing apparatus equipped with a print head capable of discharging a plurality of colors of ink (hereinafter, also referred to as a "recording head") has become widespread. As a result, the types and number of refill ink tanks have been diversified. In recent years, there have been various demands for inks, such as inks having different color tones to achieve richer expressions, inks having fluorescent properties, inks having improved water resistance and weather resistance, and the like. For this purpose, various ink tanks are prepared. It is preferable that these ink tanks can be used in common for the same printhead. However, when the ink components are largely different, they are generally used for separate printheads. As described above, when various recording heads and ink tanks are used in the same printing apparatus, it is necessary to distinguish them.

In order to cope with such a problem, for example, Japanese Utility Model Publication No. Hei 2-26678 discloses an ink tank having a plurality of chambers connected to a recording head for storing inks of different colors, and a plurality of ink tanks. At the connection portion with the ink cartridge that replenishes ink for each chamber, engaging means including an engagement portion having a different arrangement position for each color is provided, so that replacement at the time of replenishment replacement with a plurality of color ink cartridges is performed. An example in which an error is prevented beforehand is described.

[0004] For example, see Japanese Patent Application Laid-Open No. Hei 7-137400.
In the official gazette, pen of different shape is exchangeably held,
An easily replaceable pen carriage is disclosed. In this case, different sized pens can be interchangeably held at similar locations relative to the circuit mounted on the carriage.

[0005]

However, the above-mentioned prior art has the following problems.

First, the former Japanese Utility Model Publication No. 2-26678 has the following problems (1) and (2).

(1) Since the recording head and the ink tank are fixed on the carriage and cannot be replaced, it is impossible to use a cartridge storing ink having greatly different components.

(2) Even if the recording head and the ink tank can be exchanged, the shapes of the recording head and the ink tank need to be different for each ink component, so that the cost of each recording head and the ink tank increases. There is a risk. Further, as an operation for replacement, the replacement operation of the three parts of the cartridge, the ink tank, and the recording head is required, which may cause the operation to be complicated.

On the other hand, the latter Japanese Unexamined Patent Publication No. Hei 7-137400 has the following problem (1).

(1) Since the shapes of the pens to be replaced are greatly different, the same parts cannot be used, which increases the cost of the pens themselves.

As described above, conventionally, when various recording heads and ink tanks are used in the same recording apparatus, there is a problem that the operation is complicated in distinguishing them.

SUMMARY OF THE INVENTION It is an object of the present invention to prevent erroneous mounting of a plurality of types of print heads and ink tanks which can be selectively mounted, and to prevent an increase in running cost and a complicated operation when distinguishing them. It is an object of the present invention to provide a printing apparatus capable of performing the above.

It is another object of the present invention to provide a printing apparatus which enables a worker to easily identify the type of a print head and further improve operability.

[0014]

According to the present invention, there is provided a printing apparatus for performing printing on a print medium by using a print head capable of discharging ink supplied from an ink tank. A head mounting part to which a head can be mounted, a tank mounting part to which a plurality of types of ink tanks can be mounted, and the tank mounting part which can be mounted to the tank mounting part according to a type of the print head mounted to the head mounting part. Regulating means for regulating the type of the ink tank.

In addition to being configured to transmit a signal for driving the recording head, it has a configuration capable of generating a signal for identifying the type of the recording head. For example, it is possible to adopt a configuration in which the electrical characteristics such as the resistance value and the connection state of the electrical cable 406 are different depending on the type of the recording head. Therefore, it is possible to electrically identify which of the first recording head unit 101 and the second recording head unit 102 is mounted. The slide plate 11 in the first embodiment described above can be operated using an electric drive source such as a motor or a solenoid based on the thus obtained electric signal for identification.

(Other Embodiments) In the present invention, the types and the number of recording heads for ejecting ink to be mounted are not limited to only the combinations corresponding to the four color inks as in the above-described embodiment. Is obvious. Further, in the above-described embodiment, four recording heads are integrally formed as a unit, but of course, each recording head is separately provided.
The same effect can be obtained by providing a difference in the form such as a rib for each type of recording head. In addition, a plurality of recording heads may be provided corresponding to the respective monochromatic inks having different densities. For example, as a recording apparatus, not only a recording mode using general yellow, magenta, cyan, and black inks but also at least one of recording modes of multiple colors of different colors, or full-color recording modes that realize gradation expression by density modulation. The present invention is also very effective for an apparatus having one. The ribs provided on the ink tank may be configured to mount two types of ribs, for example, a first rib group indicating a color and a second rib group indicating a density of ink. According to this configuration, even when there is no dark ink tank or light ink tank, complementary printing can be performed using the tank having the same color ink. In particular, in a combination of a head for ejecting ink containing a color material and a head for ejecting a pretreatment liquid for aggregating the color material in the ink, the ink and the processing liquid may be misinserted due to erroneous insertion of those heads. The present invention is extremely effective because there is a high need to prevent mixing. Various printability improving liquids can be used as the processing liquid.

Further, in the above-described embodiment, an example of application as a so-called serial type ink jet recording apparatus has been described. However, a so-called full line type recording head having a length corresponding to the maximum printable width is also applicable. The present invention can be applied effectively. For example, it is apparent that a desired effect can be obtained by arranging a recording head for discharging the pretreatment liquid and a recording head for discharging black, cyan, magenta, and yellow in order from the upstream side of the conveyance of the recording medium. In the above-described embodiment, a configuration in which a plurality of recording heads are integrally configured as a recording head unit has been described.
It is apparent that the same effect can be obtained even if each recording head is separately provided. Further, the full-line type recording head may be either a so-called stagger type which satisfies the length by a combination arrangement of a plurality of recording heads, or a so-called in-line type which is integrally formed linearly.

The treatment liquid for insolubilizing the ink dye can be obtained, for example, as follows.

That is, after mixing and dissolving the following components,
Further, after filtration under pressure with a membrane filter having a pore size of 0.22 μm (trade name: Fluoropore Filter, manufactured by Sumitomo Electric Industries, Ltd.), the pH is adjusted to 4.8 with NaOH to obtain a treatment liquid A1. it can.

[Component of A1] Low molecular weight component of cationic compound Stearyl trimethyl ammonium salt 2.0 parts (trade name: Electrostripper QE, manufactured by Kao Corporation) or stearyl trimethyl ammonium chloride (trade name: Eutamine 86P, Kao) High molecular component of cationic compound Copolymer of diallylamine hydrochloride and sulfur dioxide 3.0 parts (average molecular weight: 5000) (trade name: polyamine sulfone PAS-92, manufactured by Nitto Boseki Co., Ltd.) Thiodi Glycol 10 parts Water Remainder In addition, the following can be mentioned as a preferable example of the ink which is mixed with the above-mentioned treatment liquid and insolubilized.

That is, the following components were mixed, and the mixture was filtered under pressure through a membrane filter (trade name: Fluoropore Filter, manufactured by Sumitomo Electric Industries, Ltd.) having a pore size of 0.22 μm, and then yellow, magenta, cyan, and black were filtered. Inks Y1, M1, C1, and K1 can be obtained.

Acid Red 289; the same composition as Y1 except that 2.5 parts were used. I. Acid Blue 9: Same as Y1 except that 2.5 parts were used. I. Food Black 2: Same composition as Y1 except that 3 parts are replaced. In the mixing of the above-described processing liquid (liquid composition) and ink, in the present invention, the above-described processing liquid and ink are applied on the printing material or on the printing material. As a result of mixing at the position where the ink has penetrated into the printing material, as a first step of the reaction, the low molecular weight component or the cationic oligomer contained in the treatment liquid and the anionic group used in the ink are used. The water-soluble dye has an association due to ionic interaction and instantaneously separates from the solution phase.

Next, in the second stage of the reaction, the above-mentioned aggregate of the dye and the low molecular weight cationic substance or cationic oligomer is adsorbed by the high molecular component contained in the processing solution, and the association is formed. The size of the aggregates of the dyes becomes even larger, making it difficult to enter the gaps between the fibers of the printing material, and as a result, only the liquid portion that has been separated into solid and liquid penetrates into the recording paper, resulting in print quality and fixability. Is achieved. At the same time, the aggregate formed by the low molecular weight component of the cationic substance or the cationic oligomer and the anionic dye formed by the mechanism described above increases in viscosity and does not move with the movement of the liquid medium, so that a full-color image is obtained. Even when adjacent ink dots are formed of different color inks as in the case of formation, they do not mix with each other, and bleeding does not occur. Also, the agglomerates are essentially water-insoluble and the formed images have perfect water resistance.
Further, it also has an effect of improving the light fastness of an image formed by the shielding effect of the polymer.

As used herein, the term "insolubilization" or "aggregation" refers to a phenomenon that occurs only in the first step or a phenomenon that includes both the first step and the second step.

In practicing the present invention, it is not necessary to use a cationic polymer substance having a large molecular weight or a polyvalent metal salt as in the prior art, or even if it is necessary to use a high-molecular metal salt, the present invention may be applied. Since it is only necessary to use it supplementarily to further improve the effect, the amount of use can be minimized. As a result, another problem of the present invention is that the decrease in the coloring property of the dye, which has been a problem in the case of using a conventional cationic polymer substance or a polyvalent metal salt to obtain a water resistance effect, is eliminated. This can be mentioned as an effect.

The printing material used in carrying out the present invention is not particularly limited, and so-called plain paper such as copy paper and bond paper conventionally used can be suitably used. Of course, a coated paper or a transparent film for OHP specially prepared for inkjet printing can be suitably used, and general high-quality paper or glossy paper can also be suitably used.

In practicing the present invention, the ink used is not particularly limited to a dye ink, but a pigment ink in which a pigment is dispersed can be used. Can be used.
