DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a perspective view showing the appearance of the electronic pen of the present invention.

A clip 11, an input mechanism 12, a discharge switch 16, and a cleaning switch 17 are arranged on a cylindrical outer casing 10 which is partially narrowed. At the end, a colorant discharge port 15 is provided. Input mechanism 1
2 is yellow 12Y, magenta 12M, cyan 12C
Are provided for each color. Then, the slider 13 using the contactless volume moves on the guide on which the scale 14 is engraved, thereby enabling input.

Next, a mechanism built in the electronic pen will be described with reference to FIG. FIG. 2 is a perspective view of the electronic pen of the present invention.

A button-shaped battery 20 is disposed at one end of the electronic pen. Below that is a substrate 21 with a built-in control mechanism. Further, adjacent to the substrate 21,
An ink tank 22 and a discharge mechanism 23 are arranged. The ink tank 22 stores three colors of yellow, magenta, and cyan colorants and a colorless cleaning liquid separately. The colorant may be any ink containing a so-called inkjet dye or pigment. Discharge mechanism 23
Has a configuration in which four ink jet heads are basically arranged. As the inkjet head, a so-called drop-on-demand type head may be used, and for example, various types such as a thermal inkjet type using foaming by heating and a type using vibration by piezo can be used.

From each of the discharge sections 23, four lead pipes 24 are connected, connected to the mixing section 25, and integrated.
From the mixing section 25, it is guided to the discharge port 15 by a nozzle 26.

Further, a block diagram of an electric control system including the substrate 21 will be described with reference to FIG. FIG.
FIG. 3 is a block diagram of the present electronic pen. This electronic pen is mainly composed of a color information input unit 101, a cleaning pulse generating unit 102, an ejection pulse generating unit 103, an ejection mechanism driving circuit 104, and an arithmetic circuit 110. The arithmetic circuit 110 includes a signal detection circuit 111
, An A / D circuit 112, and a discharge amount calculation circuit 113. The color information input unit 101 includes an input mechanism 12
And its associated circuitry. The cleaning pulse generating means 102 is provided for the cleaning switch 17.
And a pulse generating circuit generated at the end of printing. The ejection mechanism drive circuit 104 includes the ejection mechanism 23
Control. Next, the operation of the electronic pen of the present invention will be described.

The user first inputs color information before use. That is, the input mechanism 12 adjusts the slider 13 in accordance with the scale 14 in order to select a desired color. By this adjustment setting, the color information input means 101
Data is input to. This input is connected to the signal detection circuit 11
1, after the analog output, the A / D circuit 112
, And is sent to the discharge amount calculation circuit 113. The ejection amount calculation circuit 113 determines the ejection amount of each color of yellow, magenta, and cyan based on the color information digital data.

After inputting the color information, the user presses the discharge switch 16 to start the writing operation. By the discharge switch 16, a signal is input from the discharge pulse generating means 103 to the discharge amount calculation circuit 113. When the ejection data determined as described above is sent from the ejection amount calculation circuit 113 to the ejection mechanism driving circuit 104, the ejection mechanism 23 starts ejecting ink. That is, the ink sucked and discharged by the discharge mechanism 23 from the ink tank 22 of each color is integrated by the mixing unit 25 via the lead-out pipe 24 and discharged from the nozzle 26. This allows the user to write with the color specified by the user.

Further, there is a case where the set color is changed. At that time, the previous color ink remains in the outlet pipe 24, the mixing unit 25, and the nozzle 26. To remove the residual ink, the user operates the cleaning switch 1
Press 7. By this operation, an input is made to the cleaning pulse generating means 102, and the signal is transmitted to the ejection amount calculation circuit. The discharge amount calculation circuit 113 calls up a predetermined discharge amount of the cleaning liquid based on the signal and sends it to the discharge mechanism driving circuit 104. As a result, the cleaning liquid is sent out from the discharge mechanism 23, and the surplus ink and the like remaining in the above-described outlet pipe 24, the mixing unit 25, and the nozzle 26 are made to flow cleanly and discharged outside the discharge port 15. In other words, the cleaning liquid that has been discharged is discharged by the user as a blank shot, thereby completing the cleaning.

The present invention can be modified without departing from the scope of the present invention without being limited to the above embodiment. That is, the gist of the present invention is to provide a writing implement that can be controlled according to user input information. In the present invention, each color of yellow, magenta, and cyan is used as a reference as input information. For example, the color may be changed to red, blue, and green. Although a liquid inkjet recording head is used as the ejection mechanism, the same effect can be expected by using a recording head of a hot melt type solid inkjet recording method or a toner jet recording method. Further, a good effect can be expected even if a chromaticity display or the like is attached to the input mechanism.

[0022]

[Effect of the invention] As is clear from the above description,
According to the present invention, a toned colorant is created according to the color information set by the user. The user can write using the coloring agent. Therefore, it is possible to create an arbitrary color desired by the user and perform a writing operation such as marking and painting, and the effect contributed by the present invention is enormous.
