Embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

FIG. 1 shows a thermal pen device according to an embodiment of the present invention. In FIG. 1, a thermal pen 1 is composed of a pen tip member 2 that accommodates a heating element and a shaft member 3 that holds the pen tip member 2, and a power cord 4 of the thermal pen 1 is a connecting member. Through 5,
It is connected to the AC adapter device 6.

The AC adapter device 6 has a plug 6a connected to a table tap 7 connected to a commercial power source. Further, the table tap 7 has a manual switch 8 for operating on / off of the power supply to the connected device.
Is attached.

Further, as shown in FIG. 2, the thermal pen 1
In the circuit of the heating element 10 of FIG.
Also, a thermal fuse 12 is connected in series for preventing accidents during heating.

Here, as the heating element 10, it is preferable to use a carbon resistor or a ceramic semiconductor.
Further, it is preferable to use a nichrome wire, a brass wire, or an iron wire having a poor thermal conductivity for the wiring from the power cord 4 to the resistor 11 and the wiring from the power cord 4 to the thermal fuse 12.

FIGS. 3A to 3E show an example of a method of manufacturing the thermal pen 1.

First, one lead wire 16 of the carbon resistor 15 used as the heating element 10 is linearly extended, and the other lead wire 17 is bent into a substantially elliptical shape to be formed on the pen tip portion 18 (see the same figure). (See (a)).

Next, the carbon resistor 15 and the lead wire 16
In addition, a Teflon (trade name: polytetrafluoroethylene) tube 19 having a diameter corresponding to the diameter of the carbon resistor 15
(Refer to FIG. 2B), solder the wiring materials 20 and 21 for power supply to the lead wires 16 and 17, and at the same time the lead wire 17 is closely attached to the outside of the Teflon tube 19. The Teflon tube 22 is attached from the outside (see FIG. 6C).

Further, the Teflon tube 23 is inserted from the outside of the Teflon tube 22, and the portion including the soldered portions of the lead wires 16 and 17 and the wiring members 20 and 21 is covered and fixed with the heat shrink tube 24. An aluminum pipe 25 is attached to the outside of the heat shrink tube 24, and the aluminum pipe 25
The aluminum pipe 26 is attached to the outer side of the heat-shrinkable tube 24 from the vicinity of the end position (see FIG. 3D).

Then, the aluminum pipe 27 is attached to the outside of the aluminum pipe 26 from substantially the same position as the aluminum pipe 25 (see (e) in the figure), whereby the thermal pen 1 is formed.

Here, carbon resistance 15 and lead wire 1
6, 17, the Teflon tubes 19, 22, 23, and the heat shrink tube 24 form the pen tip member 2, and the aluminum pipes 25, 26, 27 form the shaft member 3.
Moreover, these Teflon tubes 19, 22, and 23 are
A heat insulating member is configured to prevent the amount of heat generated from the carbon resistor 15 from being transmitted to the shaft member 3. At the same time, the gap 28 formed between the aluminum pipe 25 and the aluminum pipe 27 functions as a heat insulating means for preventing the amount of heat transferred to the shaft member 3 from being transferred to the outside. A heat insulating member may be provided instead of the gap 28.

Therefore, most of the amount of heat generated from the carbon resistor 15 can be transferred to the pen tip portion 18,
The thermal efficiency of this thermal pen 1 becomes very good.

With the above configuration, when the AC adapter device 6 is attached to the table tap 7, the table tap 7 is connected to a commercial power source, and the manual switch 8 is turned on, the heating element of the pen tip member 2 of the thermal pen 1 is turned on. The electric power set at that time is supplied to 10, and thereby the amount of heat corresponding to the electric power is radiated from the heating element 10.

The amount of heat emitted from the heating element 10 is transferred to the tip of the pen tip member 2 (for example, the pen tip portion 18 of the lead wire 17 of the carbon resistor 15), so that the pen tip member 2 is subjected to thermal recording. When pressed against the paper, the amount of heat transferred to the pen tip member 2 is further transferred to the thermosensitive recording paper, and when the temperature of the thermosensitive recording paper reaches its coloring temperature, the thermosensitive recording paper of the pressed part is Develops color.

Thus, the thermal pen 1 can be used to record arbitrary contents by handwriting on the thermosensitive recording paper. In addition, since the recording process uses the coloring principle of the thermal recording paper as it is, the recorded contents of the thermal recording paper are very clear, and there is no chance of being caught during writing, resulting in a very smooth writing feel. Can be realized.

Here, according to the trial production by the inventor, the heating element 1
0 as 100 (ohm), 1/6 to 1/4 (watt)
3 (a) to the thermal pen 1 using the carbon resistance of
When manufactured in the step (e) and supplied with an electric power of 0.5 to 1.0 (Watt), very good handwriting input was possible on the thermal recording paper. The temperature of the pen tip at this time is 1
The heat resistance temperature of each member used is 4
Since it was about 00 °, thermal damage did not occur at all for about 200 hours of continuous use, which was a sufficiently practical level.

By the way, as shown in FIG. 4A, in the pen tip member 2, when the heating element 10 and the pen tip portion 2a are simply directly connected, the pen tip portion 2a of the heating element 10 is not connected. Heat is radiated from the opposite side, and the amount of heat in this portion is wasted. In order to avoid such a situation, the heating element 10 formed on the pen tip portion as shown in FIG.
One of the lead wires 10a may be wound around the heating element 10 so that the amount of heat of the heating element 10 is transmitted to the pen tip portion.

Further, one lead wire 10a of the heating element 10
Is connected to the pen tip portion 2a, and the other lead wire 10b is used only for power supply, as shown in FIG. 5A, half of the heat generated from the heating element 10 is the lead wire 1
0a side, and 1/2 of that is transmitted to the pen tip 2a.
1/2 of the amount of heat generated from the heating element 10 is transferred to the lead wire 10b, so that the amount of heat transferred to the pen tip portion 2a is 1/1 of the amount of heat generated from the heating element 10. 4, the thermal efficiency of the pen tip member 2 is very poor.

In order to improve the thermal efficiency of the pen tip member 2, for example, as shown in FIG.
Is composed of two divided heating elements 10 ', 10 ", one lead wire 10'a, 10" a of the heating element 10', 10 "is connected to the pen tip portion 2a, and the other lead wire 10'b. , 1
It is preferable to use 0 ″ b for power supply. In this case, half of the amount of heat generated from the heating elements 10 ′ and 10 ″ can be transmitted to the pen tip portion 2a. The thermal efficiency of the tip member 2 can be almost doubled.
