<Purpose of the invention> This invention can eliminate these various drawbacks.

The aim is to provide a recording device using a new recording method.

<Summary of the Invention> In the present invention, a rod-shaped recording material is formed from a colored conductive resin material, one end of this recording material is brought into contact with a recording paper, and an electrode is provided at the contact portion with the recording paper. melts the recording material by passing an electric current through it,
The melted recording material is deposited on the recording paper, and dots of a desired shape are printed on the recording paper by this deposition.

<Embodiment of the Invention> FIG. 1 shows an embodiment of the invention. In the figure, reference numeral 101 indicates recording paper, and reference numeral 102 indicates the above-mentioned rod-shaped recording material.

The recording material 102 is colored by adding dye to a resin material that is easily melted by heat, and is made conductive by adding conductive powder. In this example, the recording material 102 is formed into a rod-shaped body having a round cross-sectional shape. This recording material 102 is supported by a heat-resistant insulating material 1p3 such as ceramic, and one end thereof is pressed against the recording paper 101.

In this example, the means for bringing the recording material 102 into pressure contact with the recording paper 101 is omitted. Recording paper 1 of recording material 102
``Electrodes 104a and 104b are provided at the contact portion with 01, the recording material 102 is brought into contact with these electrodes 104a and 104b, and an electric current is supplied to the electrodes 104a and 104b to supply a recording current.
Connect the flow source 105. This insulating material 103 and electrode 104
a and 104b constitute a print head.

<Operation of the Invention> In the above-described configuration, by outputting a recording current from the recording current source 105, a current flows to the recording material 102 via the electrodes 104a and 104b. This current causes the recording material 10
Joule heat is generated in the recording material 102, and only the portion of the recording material 102 where the current flows is melted, and the melted portion adheres to the recording paper 101 as shown as 201 in FIG. Therefore, it is possible to print dots on the recording paper 101 that have a cross-sectional shape equal to y in the cross-sectional shape of the recording material 102. By arranging a large number of these print heads in a direction perpendicular to the paper feeding direction 106 of the recording paper 101 and applying a recording current to a head located at an arbitrary position among the print heads, analog waveforms can be created by forming figures, characters, and symbols. etc. can be recorded.

Similar recording can also be performed by scanning one print head in a direction perpendicular to the paper feeding direction of the recording paper 1010 and performing a printing operation at a desired position during the scanning period.

In addition, although the electrodes are a pair of electrodes in the above, as shown in FIG.
01b may be used.

Further, the recording material 102 may not be in the shape of a round bar, but may be in the shape of a belt, for example.
It may also be configured to print rectangular dots.

FIG. 4 shows a specific embodiment in which the recording material 102 is pressed against the recording paper 101. In FIG. In this example, an outlet 402 for the recording material 102 is formed at the peripheral edge of a flat disc-shaped case 401, and a rotating shaft 402 is formed at the center of the disc-shaped case 401.
3 is provided, and this rotating shaft 403 is rotationally biased in the expanded clockwise direction in this example by, for example, a spring 404. One end of the recording material 102 stored in a spiral shape is attached to the rotating shaft 403, and a biasing force is applied to the other end of the recording material 102 stored in a spiral shape in the direction of protruding outward from the outlet 402. The following shows the configuration. Reference numeral 405 indicates a lid that is placed over the case 401.

A conceivable structure is to consider the case 401 containing the recording material 102 as one cartridge, and to support this cartridge in a detachable manner with respect to the printing pad. FIG. 5 shows an example. A hole is formed on the back side of the insulating material 103 constituting the print head, and an outlet 402 formed protruding from the case 401 is fitted into this hole. With this fitting, p case 401
is supported relative to the print head, and further projects the end of the recording material 102 toward the recording paper 101 through a pore communicating with the hole.

By storing the recording material 102 in the case 401 in this manner, the recording material 102 can be easily replaced. Therefore, by storing recording materials of different colors in the case 401, it is possible to easily change the printing color of the recording head.

In the example shown in FIG. 4, the recording material 102 is stored in a spiral shape in the case 401, but as shown in FIG. You may also rotate it. In this case, there is an advantage that the diameter of the case 401 can be reduced.

FIG. 7 shows another embodiment of the invention. In this example, a metal piece or a conductive portion 7 with good conductivity is provided at the end end of the recording material 102.
01 is attached, and this conductive portion 701 is connected to the electrode 104.
A case is shown in which the configuration is such that when a short circuit is made between a and 104b, it is indicated that the recording material 102 is running out.

In FIG. 7, 702 indicates this display circuit. The display circuit 702 can be configured as follows, for example. A series circuit consisting of a resistor 703 and a constant voltage diode 704 is connected to both ends of the recording current source 1050, and a constant voltage is generated in the constant voltage diode 704 every time a recording current is output from the recording current source 105. A series circuit consisting of a light emitting element 705 and a light emitting element 706 is connected in series with the recording current source 105 and the electrodes 104a and 104b of the recording head. A series circuit of electrodes 104a and 104b is connected to the emitter of the tB transistor 705, and the electrodes 104a and 1 connect the base of the transistor 7050 to the connection point between the resistor 703 and the voltage regulator diode 704.
When the recording material 102 is present between the transistors 04b and 04b, the resistance value of the recording material 102 is connected in series with the emitter of the transistor 705, so that the current flowing through the transistor 705 is limited. Therefore, the light emitting element 706 does not light up in this state.

Near the end of the recording material 102, when the conductive portion 701(7) reaches between the electrodes 104a and 104b, a bias voltage in the saturation region is applied to the transistor 705. As a result, a saturation current flows through the transistor transistor 05, and the light emitting element 706 lights up.

Therefore, when the light emitting element 706 lights up, the recording material 10
You can see that 2 is gone.

FIG. 8 shows another example of displaying the end of the recording material 102.

In this example, a recording material 801 for end indication of a color different from that of the recording material 102 is connected to the end of the recording material 102, and the color of this recording material 801 for end indication appears on the recording paper, so that the recording material 102 It can be displayed that the item is gone. FIG. 9 shows an example of recording by the recording material 801 for end display. The waveform recording portion 901 is a normal recording material 1
The color part of 02 is shown. On the other hand, a portion 902 shows 8010 colors of recording material for end display.

<Effects of the Invention> As explained above, according to the present invention, since the recording material 102 can be easily replaced, the recording color can be easily replaced. Furthermore, the structure is simple because (8) the recording current is simply supplied to the electrodes 104a and 104b.

Also, unlike ink, there is no risk of staining or clogging, so maintenance is easy. Moreover, many types of colors can be prepared. Further, by providing a large number of print heads, there are advantages such as being able to perform surface recording at once, and this effect is extremely great in practical use.
