Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a recording device that selectively deposits colored matter on plain paper according to electrical signals.

Conventionally used recording methods for recording electrical signals include recording methods using processed paper such as discharge recording, thermal recording, and electrostatic recording, as well as electrophotography, magnetography, and inkjet recording. A recording method using plain paper such as .

This recording method using plain paper is frequently used in copying machines, etc., but in fields that require scanning, such as facsimile receivers, each recording method using plain paper has its own drawbacks. . That is, electrophotography and magnetography require complicated equipment and are difficult to apply to simple equipment, while inkjet recording allows for easy equipment miniaturization, but requires mechanical scanning. Because it is necessary,
The drawback was that it was less reliable than recording methods that allowed the device to be scanned electronically. In order to eliminate the drawbacks of the above-mentioned conventional examples, the present invention records by selectively energizing a colored conductive material, and the device is simple, easy to downsize, and can be scanned electronically. The present invention provides a recording device that can perform

Hereinafter, embodiments will be described in detail with reference to the drawings. Figure 1 shows
This figure shows an embodiment of the present invention, in which 1 is a colored material having conductivity and thermal adhesiveness, 2 is a roller having a layer of this colored material 1 on its surface and is grounded, 3 is an electrode, and 4 is a normal 5 is a presser roller, 6 is a recorded image, 7 is a shaping roller that makes the layer of the colored material 1 on the roller 2 uniform, 9 is a container with a built-in heater 8 and contains the colored material 1, 10 is a power source , 11 is an insulator supporting the electrode 3, and 12 is a switch.

Next, the operation of this embodiment will be explained.

First, the colored material 1 in the container 9 heated by the heater 8 is melted and attached to the roller 2. When this roller 2 rotates in the direction of the arrow, the colored material 1 reaches the shaping roller 7 while being cooled, and becomes a uniform layer there. This layer of colored material 1 then comes into contact with an electrode 3 supported by an insulator 11 . This electrode 3 is composed of a single-needle or multi-needle electrode, and applies a voltage to the colored object 1 according to an electric signal. When this voltage is applied, the electrically conductive colored material 1 generates Joule heat and is heated, and only the portion to which this voltage is applied melts. As the roller 2 rotates, this melted colored material comes into contact with the plain paper 4 adjacent to the electrode 3 for a short time, and only the melted colored material is transferred to the plain paper 4, forming an image 6. . Further, the roller 2 rotates, and after separating from the plain paper 4, it returns to the container 9.
It comes into contact with the molten colored material inside and returns to its initial state. In this case, it is preferable that the time required for the melted colored material 1 to come into contact with the plain paper 4 to be as short as possible, so it is desirable to configure the apparatus so that the plain paper 4 comes into contact with the electrode 3.
FIG. 2 shows the principle of the present invention in an enlarged view of the area around which the colored material 1 contacts the plain paper 4 in FIG. Due to the applied voltage, Joule heat is generated inside the colored material 1, and the colored material 1 is melted by this heat generation, and the plain paper 4 comes into contact with the colored material 1 while the colored material 1 is maintained in a molten state. Therefore, part or all of the melted colored material 1 is transferred onto the plain paper 4, and a fixed recorded image 6 is formed on the plain paper by cooling.
FIG. 3 shows another embodiment of the present invention using a multi-needle electrode, but in order to explain the driving of this multi-needle electrode, colored objects and plain paper are omitted.

In addition, there are 4 electrodes in groups 3, 31, y, and 3'7, respectively.
The control electrodes 13, 13', 13'', 13'7' of the roller 2 are arranged in groups 3, 13', 13'', 13'7',
They are arranged in a cylindrical shape corresponding to electrodes 3', 31, and 3'1. These control electrodes 13, 13', 1y, 13
I' is connected inside the roller 2 to a plurality of rings 15 provided on the shaft 14 of the roller 2, and the electrodes 13, 13', 13y,
13'7 can be controlled. Figure 4 shows the third
This shows the principle of the circuit that drives the multi-needle electrode shown in the figure.
The signal from the terminal S1 is accumulated in the shift register SRl, and the four pieces of information of the signal are stored in the serial/parallel conversion shift register SR2.
The gate is opened by the timing signal from the terminal G1, and the signal from the serial/parallel conversion shift register SR2 is applied to the electrodes of groups 3, 3', 3I, 3''5.

At this time, when the gate (not shown) of the control electrode 13 is opened, a current according to the applied signal is passed through the electrodes of group 3, and the electrodes of other groups 3', 3', 3''5 are controlled. Since the gates of electrodes 13', 1r, and 13m are closed, no current flows.Next, in order to apply a signal to the electrodes of group 3', the signal transferred to shift register SR2 is transferred from terminal G1. This can be done by opening the gate in response to a timing signal, simultaneously opening the gate of the control electrode 13', and closing the gates of the other control electrodes 13, 13w, 13''2. Furthermore, by sequentially performing this scanning, signals can be applied to all groups of electrodes. By using the single drive method described above, there is an advantage that a large number of electrodes can be controlled at once, and the number of gates that drive the electrodes can be smaller than the number of electrodes.

FIG. 5 shows another embodiment of the present invention in which a voltage is applied between electrodes, and the same reference numerals as in FIG. 1 indicate the same parts. At least its surface is made of an insulator, and voltage for recording is applied between adjacent electrodes.

Next, details of this embodiment will be explained with reference to FIG. 6.

First, the electrodes 3A, 3B, 3C, and 3D penetrate into the colored object 1 and make good electrical contact with the colored object 1. Here, in order to melt the colored material between the electrodes 3A and 3B, switch 1 connected to the electrodes 3A and 3B, respectively.
Close 2A and 12B. Since the electrode 10 is connected to the switch 12B, the current flows from the electrode 3B through the colored material 1 to the electrode 3A, and the colored material 1 generates heat and melts. Similarly, when the colored material between the electrodes 3B and 3C is to be melted, the switches 12B and 12C are closed while the switches 12A and 12B are not operating. The colored material selectively melted in this way immediately contacts the plain paper to form an image. Although this switch operation is complicated, a method for driving a thermal head for thermal recording that performs the same operation is known, so no particular explanation will be given here. 7th
The figure shows different embodiments for forming a layer of the colored material 1 on the roller 2. In the embodiment described above, the layer of the colored material 1 is formed by bringing the molten colored material 1 into contact with the roller 2. However, in this embodiment, the colored material is given a plastic condition at room temperature, and when it passes through the gap between the rollers 16 and 2, the layer consisting of the colored material 1 is regenerated. In this case, in order to selectively form a layer of the colored material 1 on the roller 2, the rotation of the roller 16 may be made slower than the rotation of the roller 2. The use of this colored material 1 that exhibits plasticity at room temperature has the advantage of simplifying the regeneration means when reusing the layer made of the colored material 1, and as shown in FIG.
does not require. Furthermore, in the apparatus shown in FIG. 1, the colored material 1 cannot be used until it is heated and melted by the heater 8;
The device shown also has the advantage of being ready for use. Next, FIG. 8 shows still another embodiment of the present invention, in which a colored object 1
A colored material similar to that used in FIG. 7 is used, and a doctor 17 for forming a layer of colored material 1 is fixed in place of the roller 16.

A layer of colored material 1 is formed in the gap between this doctor 17 and roller 2, and is immediately brought into contact with electrode 3 and heated, and the layer of plain paper 4 is heated.
recorded in The colored material 1 that is not used for this recording is returned to the container 18 containing the colored material and is reused. Next, colored objects will be explained.
