Japanese Patent Publication No. 2015-521325

Recently, electronic devices such as tablet terminals are being used in elementary schools to use electronic teaching materials. For example, an input pen is used when using an electronic device with a pressure-sensitive or capacitive input section. For elementary school students who are still in the process of learning how to hold writing instruments and who mainly use pencils, it is considered optimal to mainly use wood as the shaft of the input pen, which is similar in shape and weight to pencils. In addition, it is desirable that the input pen for elementary school students is inexpensive, because elementary school students often lose or damage the pen due to misappropriation of force.

In the capacitive input pen, for example, a conductive core is used to ensure capacitance, and the core and the conductive contact are electrically connected. In this case, since the capacitance of the writing lead differs depending on the density of the writing lead selected by the user (content of carbon black, etc.), the feeling of use when touching the input part of the electronic device with the conductive contact part changes. Resulting in.

SUMMARY OF THE INVENTION An object of the present invention is to provide an input pen capable of maintaining a constant feeling of use.

An input pen according to a first aspect includes a shaft, and a conductive contact portion provided at one end of the shaft and having conductivity, and a central portion of the shaft having conductivity and the A non-writing conductive core electrically connected to the conductive contact and a non-conductive core that is not conductive and is arranged in series with the conductive core, or the shaft is conductive and It is electrically connected to the conductive contact and has no core at the center of the shaft.

With this input pen, by bringing the conductive contact portion into contact with an electronic device whose input portion is a capacitive type, it is possible to perform input to the electronic device. In addition, this input pen has a non-writing conductive core in the center of the shaft and a non-conductive core arranged in series with the conductive core, or the shaft has conductivity and the shaft has It has a structure that does not have a core in the center of the core.

When the input pen has a conductive core and a non-conductive core, the conductive core is arranged in series with the non-conductive core, so that the conductive core ensures a certain capacitance. Therefore, the feeling of use of the conductive contact portion can be kept constant without being affected by the difference in capacitance of cores other than the conductive core. Even if the input pen does not have a core, since the shaft has conductivity and is electrically connected to the conductive contact portion, the feeling of use of the conductive contact portion can be kept constant.

In addition, input can be performed by pressing the core or shaft of an input pen against an electronic device whose input unit is a pressure-sensitive type.

A second aspect is the input pen according to the first aspect, wherein a conductive writing core is provided in series on the side opposite to the conductive core side of the non-conductive core at the center of the shaft body. ing.

In this input pen, since a conductive writing lead is provided in series on the opposite side of the non-conductive core to the conductive core, writing can be performed using the writing lead. The capacitance of the writing lead varies depending on the concentration (content of carbon black), but since a non-conductive core is placed between the writing lead and the conductive core for insulation, the capacitance varies depending on the concentration of the writing lead, etc. The capacitance of the conductive core is not affected. Therefore, the feel of use of the conductive contact portion can be kept constant.

Moreover, in the input pen according to the first aspect or the second aspect, the non-conductive core is a colored core for writing.

In this input pen, since the non-conductive core is a colored core for writing, it is possible to write using the colored core. Since the color core is a non-conductive core, the capacitance of the conductive core is not affected by the type of color core. Therefore, the feel of use of the conductive contact portion can be kept constant. When the color core is arranged between the ink core and the conductive core on the side of the conductive contact portion, the color core is exposed after the ink core is used up, so writing with the color core is possible.

Moreover, in the input pen according to the first aspect or the second aspect, the conductive core is a conductive resin.

In this input pen, since the conductive core is made of conductive resin, it is possible to reduce the cost and weight as compared with the case where the conductive core is made of metal.

Moreover, in the input pen according to the first aspect or the second aspect, the non-conductive core is a resin molded in two colors with the conductive core.

Since the non-conductive core is a conductive resin and a two-color molded resin, the manufacturing man-hours are reduced compared to the case where the non-conductive core and the conductive core are separately molded and arranged in the shaft body. can do.

A third aspect is the input pen according to the first aspect or the second aspect, wherein at least the outer surface of the shaft has conductivity, and the conductive contact portion has conductivity and It is fixed to the shaft by contacting fixing members.

In this input pen, the conductive contact portion is fixed to the shaft by a fixing member. At least the outer surface of the shaft is conductive, and the fixing member is also conductive. Since the fixing member is in contact with the conductive contact portion and the outer surface of the shaft, the conductive contact portion and the shaft are electrically connected. Therefore, the shaft also bears part of the capacitance of the input pen.

In the input pen according to the third aspect, the shaft body is made of wood having a conductive outer surface.

In this input pen, since the shaft is made of wood having a conductive outer surface, the shape and weight are close to those of a pencil. Therefore, it is possible to provide an input pen that is easy for elementary school students to use.

A fourth aspect is the input pen according to the third aspect, wherein the fixing member fixes the shaft and the conductive contact portion by forming a plurality of inward projections.

In this input pen, the fixing member fixes the shaft and the conductive contact portion by forming a plurality of inward projections, so that the shaft and the conductive contact portion can be easily fixed.

The central portion of the shaft 12 is, for example, hollow (tube-shaped) through which the conductive core 16 and the color core 18 are arranged. Although the cross-sectional shape of the shaft 12 is arbitrary, it may be hexagonal, circular, elliptical, or quadrangular, for example. The shaft 12 may be made of conductive resin or may be made of non-conductive resin. The shaft 12 may be made of a non-conductive material such as wood or non-conductive resin, and a conductive surface 12A (see FIGS. 4 to 8) may be applied to the outer surface.

The conductive contact portion 14 is provided at one end of the shaft 12 and is, for example, a soft contact plug having conductivity. The conductive contact portion 14 is fixed to the shaft 12 by a fixing member 22 . The fixing member is a crimping member (ferrule) made of metal or resin having conductivity, and is for example crimped to the shaft 12 and the conductive contact portion 14 to connect the shaft 12 and the conductive contact portion 14 . are doing.

The conductive core 16 is a non-writing core that is conductive and electrically connected to the conductive contact portion 14 at the center of the shaft 12 . The conductive core 16 is made of, for example, a conductive resin, and its rear end is in contact with the conductive contact portion 14 . The total length of the conductive contact portion 14 and the conductive core 16 in the axial direction of the input pen 10 is, for example, 20 mm or more and less than 90 mm.

The color core 18 has no electrical conductivity and is arranged in series with the conductive core 16 . The color core 18 is arranged on the opposite side of the conductive contact portion 14 with respect to the conductive core 16 . In other words, in the input pen 10 , the color core 18 is arranged on the front end side, the conductive contact portion 14 is arranged on the rear end side, and the conductive core 16 is arranged between the color core 18 and the conductive contact portion 14 .

Therefore, the feeling of use of the conductive contact portion 14 can be kept constant without being affected by the difference in capacitance of cores other than the conductive core. Even when the input pen does not have a core, since the shaft 12 has conductivity and is electrically connected to the conductive contact part 14, the use feeling of the conductive contact part 14 can be kept constant.

In addition, input can be performed by pressing the core of an input pen or the shaft 12 against an electronic device whose input unit is a pressure-sensitive type.

Furthermore, since the non-conductive core is the color core 18 for writing, it is possible to write using the color core 18 . Since the color core 18 is a non-conductive core, the capacitance of the conductive core 16 is not affected by the type of color core 18 . Therefore, the feel of use of the conductive contact portion 14 can be kept constant. Since the conductive core 16 remains even after the color core 18 is consumed, the input pen 10 can be used as a capacitive touch pen.

Moreover, since the conductive core 16 is made of a conductive resin, it is possible to reduce the cost and weight as compared with the case where the conductive core 16 is made of metal.

Furthermore, since the shaft 12 is made of wood, the shape and weight are similar to that of a pencil. Therefore, it is possible to provide an input pen that is easy for elementary school students to use.

The ink core 24 and the color core 18, and the color core 18 and the conductive core 16 are in contact with each other.

In the input pen 20 according to the present embodiment, the ink core 24, which is a conductive writing core, is provided in series on the side opposite to the conductive core 16 side of the color core 18, which is a non-conductive core. It is possible to write using the ink core 24 . The capacitance of the ink core 24 varies depending on the density (content of carbon black). The density of the ink core 24 does not affect the capacitance of the conductive core 16 . Therefore, the feel of use of the conductive contact portion 14 can be kept constant.
