Therefore, in the printer apparatus of this example,
Ink and fragrance of each color can be freely combined.

A schematic block diagram of the printing system of such a printer device is shown in FIG. FIG. 10 shows only the printing system portion of the block diagram of the printing and control system in the liquid jet recording apparatus shown in FIG.

First, the print signal of the signals indicated by the signal input 21 in FIG. 3 is input from the host system 51 to the printer control unit 52. This printer control unit 52 is shown in FIG.
The print processing section of the signal processing control circuit 22, the memory 25, and the correction 26 is collectively referred to.

In the printer control section 52, the print signals are arranged in the print order as described above, and the presence / absence or the type of the fragrance is selected by the predetermined selecting means. When there is addition of a fragrance and it is necessary to select the type, the fragrance selected from the plurality of kinds of fragrances 53a, 53b, 53c is detected by the fragrance detection sensor,
The information is sent to the printer controller 52.

A plurality of such fragrances 53a, 53b, 5
Since 3c is stored in the fragrance tank as described above, it is necessary to provide the fragrance tank with a distinguishing unit to distinguish these fragrances.

As such discrimination means, for example, a discrimination method based on 4-bit information can be mentioned. That is, as schematically shown in FIG. 11, four switches for discriminating the information "1" by being vertically movable and pressed against the one main surface 54a as the perfume type discriminating unit 54 of the perfume type detecting sensor. , Switch A55a, switch B55b, switch C55c, and switch D55d. At this time, since the four switches are not pressed, the fragrance type determining unit 94 determines the information “0000”.

On the other hand, for example, recesses 56a and 56d are provided at positions corresponding to the switch A55a and the switch D55d on a part of the fragrance tank 26. When the fragrance tank 26 is put on the fragrance type determining unit 54 as shown by an arrow M in the figure, a switch A55 is provided as shown in FIG.
a and the switch D55d are housed in the recesses 56a and 56d, while the switch B55b and the switch C55c are stored.
Is pressed against the fragrance tank 26 as indicated by an arrow P in the figure,
The fragrance type determining unit 54 determines the information “0110”. Then, this information is sent to the printer control unit 52.

That is, if such a recess is formed in each fragrance tank in a different pattern, the kind of the fragrance tank can be easily discriminated by the fragrance type discriminating section 54 and the fragrance can be easily discriminated.

As the discrimination means, in addition to the above-mentioned method, a perfume tank is provided with an electrically conductive part and a non-conducting part, which is provided with a reflective / non-reflective seal and is discriminated by the presence or absence of this reflection. A method of making a determination based on the presence or absence of electrical continuity may be used.

Subsequently, the printer controller 52 sends information to the driver 23 also shown in FIG. 3, and this driver 23 drives the head 24 (print head) also shown in FIG. The ink 57 is supplied, the ink is ejected, and recording is performed.

At this time, in the printer device of this example, the printer control unit 52 also sends information to each fragrance supply unit 58, and each fragrance supply unit 58 selects the selected fragrance for the head 24. And then added to the ink before ejection.

As a result, the head 24 forms a recorded image containing no fragrance or containing a selected fragrance.

As the means for selecting the fragrance in the printer controller 52, the following may be mentioned. That is, as the first means, there is an arbitrary selection. Thus, in the case of arbitrary selection, the operation panel 59 is connected to the printer control unit 52 in advance,
It is sufficient to make an input from the operation panel 59 to select the presence or absence of the fragrance or the type.

As a second means, there is one that is automatically selected according to the image information to be printed. Specifically, for example, the presence or absence of a fragrance is automatically selected according to the color tone of image information, or the fragrance is automatically selected according to the color tone. More specifically, if the color tone of the image information has a strong yellowish tint, lemon oil is selected, and if it has a strong reddish tone, a rose-based fragrance is selected. The selection of the presence and type of such fragrance,
It may be performed in accordance with the characters formed by the image information. For example, if the image information forms the characters "flower", select a fragrance having a fragrance of flowers, or change the characters "strawberry". When it is formed, selection means such as selecting strawberry oil can be used.

Such conditions can be set by the host system 51, and it is also possible to arbitrarily select whether or not to drive this automatic setting.

Further, as a third means, there is a means which is automatically selected according to the ambient temperature. In this case, the presence or type of the fragrance with respect to the temperature is determined in the host system 51, a temperature sensor (not shown) is connected to the printer control unit 52, and selection according to the temperature is performed based on the information of the temperature sensor. Good.

In such a printer device, after the first fragrance is selected and added to, for example, the ink 41 and discharged from the first nozzle 31, recording is performed, and then the first fragrance is recorded during non-recording. It is desirable that only the ink 41 is ejected from the nozzle 31 to wash the inside of the first nozzle 31, and then the second fragrance is selected and added to the ink 41 for recording.

The printer device of this embodiment described above has the fragrance tank 26 in which, for example, the fragrance 42 is stored, and, for example, the ink 41 is transferred from the ink tank 22 to the first nozzle 31.
It is possible to select to add the fragrance 42 to the ink 41 in the middle of the supply to the first nozzle 3
Since the ink 41 to which the fragrance 42 is selectively added from 1 is ejected, either the ink containing the fragrance 42 or the ink not containing the fragrance 42 can be ejected, and a recorded image having an aroma and a recorded image having no aroma Any of these can be formed.

Further, in the above-described printer device of the present embodiment, a plurality of fragrance tanks 26, 27, 28, 29, 30 respectively containing fragrances of different fragrances are arranged, and the above-mentioned selection means is used to select the fragrances. It is also possible to select a predetermined type from among a plurality of types of fragrances and add it to the ink. For example, it is possible to change the fragrance for each recorded image.

In the printer of this example,
After the first fragrance is selected and added to the ink 41 to be ejected for recording, only the ink 31 is ejected during non-recording, and the second fragrance is selected and added to the ink 41. If the ink is discharged and recording is performed again, it is difficult for the fragrance to be mixed.

In the above example, the example in which the fragrance tank is provided has been described, but in the printer apparatus of this example,
As shown in FIG. 13, even if a plurality of ink tanks 62, 63, 64, 65 are replaceably arranged on the side of the main surface 21b opposite to the one main surface 21a serving as the nozzle opening surface of the head block 21. good. It should be noted that here, only parts different from the above-described printer device will be described.

Then, the plurality of ink tanks 62, 6
The inks of the above-mentioned respective colors containing the fragrances having different fragrances are contained in 3, 64 and 65, respectively.

As a matter of course, the plurality of ink tanks 62, 63, 64, 65 are as shown in FIG. 14 (in FIG. 14, only the ink tank 62 filled with, for example, yellow ink is shown. .) For the first nozzle formed for each color (in FIG. 5, only the first nozzle 71 formed for yellow is shown) to the supply path (the supply path in FIG. 14). Only 72 is shown.).

Therefore, the fragrance 82 is discharged from the first nozzle 71.
The ink 81 containing is ejected. This also applies to the other ink tanks 63, 64, 65 and the corresponding first nozzles, and each color of ink containing a fragrance is ejected from each first nozzle. A recorded image having is formed.

In the printer of the present embodiment described above, for example, the ink 81 containing the fragrance 82 in the ink tank 62.
Is stored, and the ink 81 is discharged from the first nozzle 71.
As a result, the fragrance is dispersed in the recorded image to be recorded and a recorded image having an aroma is formed.

In the above example, the example in which the fragrance and the ink are ejected from the same nozzle has been described, but the printer device of this example has a plurality of fragrance tanks in which the fragrances having different fragrances are stored. Alternatively, these fragrance tanks may be connected to the second nozzle 93 formed adjacent to the first nozzle 92a for ejecting the ink 94, for example, of the head block 91 as schematically shown in FIG. In this case, as shown in FIG. 16, a nozzle row 92 in which a plurality of first nozzles 92a for ejecting ink and a plurality of third and fourth nozzles 92b, 92c for ejecting ink of other colors are formed side by side The second nozzle 93 may be formed adjacent to the first nozzle 92a. FIG.
As shown in FIG. 5, a plurality of first nozzles 92a, third nozzles 92b, and fourth nozzles 92c are formed in rows, and these rows are formed so that nozzles corresponding to different colors are adjacent to each other, A plurality of second nozzles 93 may be formed so as to be adjacent to the first nozzles 92a of the nozzle row 96 configured by nozzles corresponding to the colors.

In this print head 91, as shown in FIG.
As shown in FIG. 5, the ink 94 is discharged from the first nozzle 92a.
At the time of ejecting, the fragrance 95 is ejected from the second nozzle 93 toward the ink adhered portion. Therefore, dots of the ink 94 containing the fragrance 95 are formed on the print paper 1, and an aroma as shown by an arrow H in the figure is generated, so that a recorded image having an aroma is formed.

FIG. 18 shows a schematic block diagram of a printing system of such a printer device. This FIG. 18 shows only the printing system portion of the block diagram of the printing and control system in the liquid jet recording apparatus shown in FIG. 3 similarly to FIG.
