  Since the conventional touch pen is configured to grip a straight round bar, the position to be gripped is not specified in the axial direction, and the position is different every time it is gripped. In other words, since the length from the gripping position to the tip portion is gusseted, the feeling of use is not unified, and mistouching the keyboard or the like is caused. Further, since a straight round bar is gripped, there is a problem that slipping easily occurs in the gripped state, which further causes a mistouch on a keyboard or the like. As a result, the input work, which is often continued for a long time, is irritated and causes substantial trouble.

On the other hand, conventional touch pens cannot prevent dust from adhering to static electricity, and may cause dust to adhere to a keyboard or the like when used with dust attached. It was. In particular, when used for a touch panel formed of a cathode ray tube or a liquid crystal screen, this problem has been a serious problem because the touch panel itself has a property of sucking dust.
The present invention has been made in view of the above circumstances, and an object thereof is to provide a touch pen that is easy to grip, can unify the grip position, and can easily perform input operations using a keyboard or the like without mistouching. To do.

  It is another object of the present invention to provide a touch pen that can prevent adhesion of dust caused by static electricity and prevent adverse effects on a keyboard, a touch panel, and the like.

In order to achieve the above object, the present invention has taken the following measures.
That is, the touch pen according to the present invention has a gripping bar part and a pen shaft part protruding from the gripping bar part with a diameter smaller than that of the gripping bar part, and is made of an elastic material at the tip of the pen shaft part. The pen tip is provided, and the gripping bar portion is provided with a constricted portion formed by narrowing the outer diameter at a position close to the pen shaft portion, and the constricted portion is formed along with the formation of the constricted portion. The middle thick part generated between the pen shaft part and the tail thick part formed in a state in which the middle thick part protrudes in the opposite direction from the constricted part. The constricted part is divided between the middle thick part and the tail part. It is formed in a state in which the connecting position with the thick part is a valley-shaped annular recess.

Thus, since the gripping bar portion has a constricted portion provided as a valley-like annular recess, the gripping rod portion can be gripped by hooking the fingertip onto the constricted portion. For this reason, it is easy to grip and difficult to slide in the axial direction, so that the gripping position can be unified, and the input operation using the keyboard or the like can be easily performed without mistouching.
In the Ogata thick part, it is preferable to provide a long flat surface part along the axial direction of the Ogata thick part with respect to the equidistant position where the circumferential direction is divided into a plurality.
This makes it easier to grip. Further, it becomes difficult to slip even in the circumferential direction (rotational direction) of the gripping bar portion.

It is preferable that the plurality of flat surface portions provided in the Ogata thick portion not reach the constricted portion. By doing in this way, a bulge part thicker than the flat part is formed between the flat part and the constricted part, and a step is generated at the boundary between the bulge part and the flat part. become.
This makes it easier to grip. In addition, since the level difference associated with the bulging portion is generated in the Ogata thick portion as described above, it is possible to arbitrarily select a gripping method in which a fingertip is hooked here, and a handling method according to individuality (gripping rod) There is an advantage that can be accommodated.
The flat plane part provided in the Ogata thick part can be made into a total of four surfaces in the circumferential direction of the Ogata thick part.

Of the total four flat surfaces provided in the Ogata thick part, it is preferable that the opposing two-surface width dimensions are 8 mm or more and 14 mm or less.
If it is less than 8 mm or exceeds 14 mm, it is difficult to grip the Ogata thick section, and if the Ogata thick section is held for a long time, fatigue or local discomfort may occur.
It is preferable that the middle thick part is provided with a depression corresponding to the fingertip with respect to the equidistant position where the circumferential direction is divided into a plurality.

This makes it easier to grip. In addition, since the hollow part is also provided in the middle thick part in this way, it is possible to arbitrarily select a gripping method such as hooking a fingertip here, and it is possible to cope with a handling method (gripping hook) according to individuality There is.
It is preferable to form a total of four depressions provided in the middle thick part in the circumferential direction of the middle thick part.
It is preferable that the length from the rear end of the Ogata thick part in the gripping bar part to the tip of the pen tip in the pen shaft part is 100 mm or more and 150 mm or less. In this case, the length of the Ogata thick part in the gripping bar part The thickness is preferably 60 mm or more and 90 mm or less.

  In terms of handling, it is convenient to set the length from the rear end of the Ogata thick portion in the gripping bar portion to the tip of the pen tip in the pen shaft portion to be from 100 mm to 150 mm. If it is less than 100 mm, it will enter the hand, and the rear end of the gripping bar portion cannot be supported (a suspended state that cannot be applied), which may cause instability. Also, if it exceeds 150 mm, it will not fit in the hand and it will be in a state where it cannot support the rear end of the gripping bar part (a state that is specified as a gripping method having a brush for writing brush), so it will take a long time. There is a possibility that it becomes easy to get tired by gripping.

Further, when the length of the thick-tailed portion of the gripping bar portion is less than 60 mm or exceeds 90 mm, it becomes difficult to use the constricted portion as a fingertip hook.
It is preferable that the rear end of the Ogata thick part in the gripping bar part is formed in a hemispherical shape.
In this way, there is an advantage that the stimulation to the abdominal surface of the palm or finger can be alleviated when the gripping method is performed such that the rear end of the tail-shaped thick part is brought into contact with the abdominal surface of the palm or finger. That is, a gripping method is possible in which the rear end of the tail-shaped thick part is brought into contact with the palm or the abdominal surface of the finger. This point also has an advantage of being able to deal with a handling method (gripping heel) according to individuality.

It is preferable that all outer surfaces except the nib are covered with a metal coating.
By doing so, since static electricity is less likely to be generated, it is possible to prevent dust from adhering to the static electricity, thereby preventing an adverse effect on the keyboard, touch panel, and the like. It can also be used in clean rooms.
In addition, although it is good also as a countermeasure against static electricity by making all except a pen tip into metal, if it does in this way, the touch pen as a whole will become heavy, and there exists a possibility that it may become inconvenient to handle. Therefore, it is conceivable that everything except the nib is made of light metal such as aluminum. However, considering the processing cost and material cost in production, it should be made of resin and covered with a metal coating. This is preferable.

With the touch pen according to the present invention, it is easy to grip, the gripping position can be unified, and an input operation using a keyboard or the like can be easily performed without mistouching.
Moreover, in the touch pen according to the present invention, it is possible to prevent dust from adhering due to static electricity, so that adverse effects on the keyboard, touch panel, and the like can be prevented.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
1 to 6 show an embodiment of a touch pen 1 according to the present invention, and FIGS. 7 and 8 show examples of its use. The touch pen 1 has a gripping bar portion 2 and a pen shaft portion 3 protruding from the tip of the gripping rod portion 2, and a pen tip 4 is provided at the tip of the pen shaft portion 3. . The other parts excluding the nib 4 are formed of an appropriate resin such as polycarbonate, PP, or ABS. All the outer surfaces except the nib 4 are covered with a metal film by metal vapor deposition or plating.

The pen shaft portion 3 is formed with a smaller diameter than the grip rod portion 2. The nib 4 is made of an elastic material such as silicon, urethane, or rubber, and has abundant cushioning effect against force and scratch prevention effect against scratching. It is designed to prevent breakdowns and scratches. The pen tip 4 may be placed on the tip of the pen shaft portion 3 as being formed in a cap shape, or may be adhered to the tip of the pen shaft portion 3 as being formed in a small tip shape. Also good.
As is clear from FIGS. 7 and 8, the gripping bar portion 2 is a portion for gripping the touch pen 1, and is formed with a thickness and length suitable for gripping with one hand. The gripping bar portion 2 is provided with a constricted portion 5 at an intermediate portion in the longitudinal direction thereof, and is divided into an intermediate thick portion 6 and an octopus thick portion 7 as the constricted portion 5 is formed.

The constricted portion 5 is positioned closer to the pen shaft portion 3, the middle thick portion 6 is formed between the constricted portion 5 and the pen shaft portion 3, and the Ogata thick portion 7 is formed from the constricted portion 5. It occurs in a state protruding in the opposite direction to the middle thick portion 6.
The constricted portion 5 is adapted to reduce the outer diameter of the gripping rod portion 2 and is formed in a state where the connecting position between the middle thick portion 6 and the tail thick thick portion 7 is a valley-folded annular recess. .
The Ogata thick portion 7 is provided with a flat flat portion 10 that is long along the axial direction of the Ogata thick portion 7 with respect to the equidistant position where the circumferential direction is divided into a plurality. In the present embodiment, the flat flat surface portion 10 has a total of four surfaces (that is, equidistant positions every 90 °) in the circumferential direction of the Ogata thick portion 7.

Each flat surface portion 10 is formed along the axial direction of the Ogata thick portion 7, but has not yet reached (not reached) the constricted portion 5. Along with this, a bulging portion 11 is formed between the Ogata thick portion 7 and the constricted portion 5. Therefore, a step 12 is generated at the boundary between the bulging portion 11 and the flat surface portion 10.
Of the flat surface portion 10, the opposing width W1 is 8 mm or more and 14 mm or less. When W1 is less than 8 mm or exceeds 14 mm, it is difficult to grip the Ogata thick portion 7, and if the gripping state is continued for a long time, there is a risk of fatigue or local discomfort.

The rear end 7a of the Ogata thick portion 7 is formed in a hemispherical shape. The rear end 7a of the Ogata thick portion 7 is provided with a through hole 15 that can be used to pass a strap or the like.
The middle thick part 6 is provided with a depression 17 corresponding to the fingertip with respect to the equidistant position divided into a plurality of circumferential directions. Although the dent part 17 of the example is assumed to have a teardrop shape, it is not limited to this.
The depressions 17 are formed on a total of four surfaces in the circumferential direction of the middle thick portion 6 (that is, equidistant positions every 90 °). Of the depressions 17, the opposing width W2 is preferably about 6 mm or more and 10 mm or less.

The total length of the touch pen 1 (the length from the rear end of the thick tail portion 7 in the gripping bar portion 2 to the tip of the pen tip 4 in the pen shaft portion 3) L1 is formed to be 100 mm or more and 150 mm or less. It is convenient in handling that L1 is a dimension of 100 mm or more and 150 mm or less.
If L1 is less than 100 mm, the gripping bar 2 enters the hand, and the rear end of the gripping bar 2 cannot be supported (a halfway state in which it cannot be applied). There is a risk. Further, when L1 exceeds 150 mm, the gripping bar portion 2 does not fit in the hand, and the rear end of the gripping rod portion 2 cannot be supported (a state that is specified as a gripping method having a brush for writing brush). Therefore, there is a possibility that fatigue may be easily caused by long-time gripping.

Further, the length L3 of the Ogata thick portion 7 is formed to be 60 mm or more and 90 mm or less. When L3 is less than 60 mm or exceeds 90 mm, it becomes difficult to use the constricted portion 5 as a fingertip hook.
In the present embodiment, the total length L1 of the touch pen 1 is 134 mm, the total length of the gripping bar portion 2 (the total length of the middle thick portion 6 and the thick tail portion 7) L2 is 100 mm, and the length L3 of the thick tail portion 7 is 74 mm. The length L4 of the middle thick portion 6 was 26 mm. Further, the opposing two-surface width W1 of the flat flat portion 10 in the Ogata thick portion 7 was 10 mm, and the opposing two-surface width W2 of the hollow portion 17 in the intermediate thick portion 6 was 7.5 mm.

As described in detail above, the touch pen 1 according to the present invention has the constricted portion 5 provided as a valley-folded annular recess with respect to the gripping rod portion 2, and as shown in FIG. It can be gripped by hooking a fingertip on the constricted portion 5.
For this reason, it is easy to grip and difficult to slide in the axial direction, so that the gripping position can be unified, and the input operation using the keyboard or the like can be easily performed without mistouching.
When the fingertip is extended slightly forward from the gripping state of FIG. 7, the fingertip can be hooked on the hollow portion 17 of the middle thick portion 6, and there is an advantage that it can be handled in accordance with the handling method (gripping hook) according to individuality. In this case, there is an advantage that it is difficult to slip even in the circumferential direction (rotation direction) of the gripping bar portion.

On the other hand, since the Ogata thick portion 7 has a flat surface portion 10 and a step 12 associated with the bulging portion 11, as shown in FIG. 8, gripping such that a fingertip is hooked on the flat surface portion 10 or the step 12. The method can be arbitrarily selected, and there is an advantage that it is possible to cope with a handling method (gripping rod) according to individuality. Also in this case, there is an advantage that it is difficult to slip in the axial direction and the circumferential direction (rotation direction) of the gripping rod portion.
By forming the rear end 7a of the Ogata thick part 7 in a hemispherical shape, as shown in FIG. 7 and FIG. 8, the gripping method is such that the rear end 7a of the Ogata thick part 7 touches the abdominal surface of the palm or finger. When this is done, there is an advantage that the stimulation to the abdominal surface of the palm or finger can be alleviated. That is, a gripping method is possible in which the rear end of the tail-shaped thick portion 7 is brought into contact with the palm or the abdominal surface of the finger. This point also has an advantage of being able to deal with a handling method (gripping heel) according to individuality.

Since all the outer surfaces except the nib 4 are covered with the metal film, static electricity is less likely to be generated, and it is possible to prevent the adhesion of dust caused by static electricity. Therefore, there is an advantage that it is possible to prevent adverse effects on the keyboard, the touch panel, etc., and it is possible to cope with use in a clean room or the like.
By the way, this invention is not limited to the said embodiment, It can change suitably according to embodiment.
