Description

  The present invention relates to a touch pen used for inputting information from a touch panel such as a personal computer game machine, an electronic notebook, or a computer.

2. Description of the Related Art Conventionally, a touch panel system using a touch pen as an input means such as an electronic notebook or a computer game machine has been widely used.
The touch pen used for the touch pen is the same as the tip of a short pen shaft (for example, about 7 to 8 cm) or a different structure so that it can be stored in an electronic notebook or computer game machine body. The pen tip is integrally inserted and fixed to the tip of the pen shaft.

However, since the pen tip in the touch pen is always exposed, there is a problem that the pen tip is soiled or damaged.
For this purpose, a pen tip has been developed and proposed that allows the pen tip to protrude and retract with respect to the pen shaft, protrudes from the tip of the pen shaft when used, and is stored in the pen shaft after use (for example, Patent Document 1).

In the touch pen described in the above cited reference 1, the pen core protrudes from the base when the knock body is pressed, and the pen core is immersed in the base by pressing the knock body again. The immersion operation is performed by the elastic force of the coil spring built in the base.
The coil spring is generally fitted and mounted on the pen tip. In the cited document 1, the coil spring is not shown or described.

Therefore, when the base attached to the tip end of the pen shaft by a screw structure or the like is removed, the coil spring jumps out due to the release of the elastic force and is lost.
The nib (nib tip) is made of a soft resin (for example, high-density polyethylene) so as not to damage the touch panel surface. Connected to. However, since the pen tip is a soft material as described above, it has a problem of bending when it is press-fitted to a pipe.

Registered Utility Model No. 3034638

The present invention has been made in view of the problems of the above-described conventional technology. The purpose of the present invention is that even when the base is removed from the pen shaft, the coil spring mounted on the tip of the pen jumps out and is lost. The aim is to provide a touch pen that is perfect.
Another object is to provide a touch pen that can improve the strength (press-fit strength, bending strength) of the connecting portion between the nib tip and the pipe.

The technical means taken by the present invention in order to achieve the above-described object is that the pen nib is a knock type steering mechanism in which a pipe connected with a nib tip is accommodated in the pen shaft and attached to the rear part of the pen shaft. In the touch pen in which the tip protrudes from the tip of the pen shaft tip, the nib tip is connected to the resin pipe via a joint fitting, and a spring drop-off stopper is formed on the rear outer peripheral surface of the nib tip. The rear end of the coil spring is engaged with the stopper.
The knock type steering mechanism may be either a head knock type or a horizontal knock type (sliding type) that is generally employed today in writing instruments (ballpoint pens).
The pen tip is formed of a soft material that does not damage the touch panel surface, for example, high-density polyethylene.

  According to the above means, since the joint metal fitting exists between the nib tip and the resin pipe, the resin pipe and the nib tip can be firmly connected, and the resin pipe and the nib tip are aligned in a straight line. Can be formed. And since the coil spring fitted to the tip of the pen tip is engaged with the tip of the tip of the tip, the coil spring is firmly attached to the tip of the tip of the pen even when the base of the tip of the pen shaft is removed. , Can be prevented from jumping out and lost.

The joint fitting may be only a metal rod that is press-fitted across both the resin pipe and the nib tip. It is more effective if the latching part to prevent is formed (Claim 2).
The locking part prevents the resin pipe and the nib tip from moving relative to the joint fitting in the removal direction. It can be stopped.

  According to the above means, since the resin pipe and the nib tip are stopped in the removal direction by the locking portion of the joint fitting, the connection state between the resin pipe and the nib tip can be stably maintained over a long period of time. Can hold.

Further, the spring drop-off stop is composed of a spring stop that stops the coil spring from moving to the rear side of the resin pipe, and a protrusion that protrudes from the spring stop at a predetermined interval toward the pen tip. (Claim 3).
The spring stopper and the protrusion may be in any form such as a ring shape continuous in the circumferential direction on the outer peripheral surface of the nib tip, or a protrusion formed discontinuously at a predetermined interval in the circumferential direction.

  According to the above means, the rear end (upper end) of the coil spring is held and held between the spring stopper and the ridge arranged in parallel to the axis so that the coil spring can be prevented from falling off. Therefore, even if the base is removed from the pen shaft, the coil spring does not scatter and a stable projecting operation can be maintained.

Furthermore, the outer diameter dimensions of the resin pipe and the nib tip are substantially the same as the pipe outer diameter and the ball tip outer diameter of the standard ballpoint pen replacement core.
In that case, various pen shafts can be supported, and various standards can be easily accommodated by changing the length of the pipe. It is also possible to take out the extra lead from the ballpoint pen and set a pipe attached with a pen tip instead to make a touch pen.

According to the first and third aspects of the touch pen of the present invention, it is possible to form a touch pen that is firmly connected without the tip of the pen tip being bent with respect to the pipe. The return coil spring that immerses the tip of the nib into the base is held in engagement with the tip of the nib, so that the coil spring does not fly away even if the pen shaft and base are separated. In addition, it is possible to provide a touch pen that can secure a stable appearance operation for a long time.
According to the configuration of the second aspect, the connection state between the resin pipe and the nib tip can be stably maintained for a long time.
Furthermore, according to the configuration of the fourth aspect, it is possible to cope with various pen shafts, and it is possible to easily cope with various standards by changing the length of the pipe.

Hereinafter, an example of implementation of the touch pen according to the present invention will be described with reference to the drawings.
A touch pen A according to the present invention includes a pen shaft 1 formed of a synthetic resin material in a hollow shaft shape, a base 2 that is detachably connected to one end of the pen shaft 1 with a screw structure, and is inserted into the pen shaft 1. A resin pipe 4 having a nib tip 3 connected to the tip, a knock-type operation mechanism 5 that causes the nib tip 3 to be moved in and out of the base 2, and a return type that causes the nib tip 3 to be immersed in the base Coil spring 6.

  The pen shaft 1 is formed in substantially the same size as a pen shaft used in a known knock type ballpoint pen, and a base 2 is detachably connected to one end of the pen shaft 1 by a screw structure. The other end of the pen shaft 1 is opened so that the knock body 5a of the knock-type steering mechanism 5 housed therein protrudes.

  The knock-type steering mechanism 5 is the same as that used in a known knock-type ballpoint pen. The knock body 5a of the operation portion and the resin pipe 4 are moved to the base 2 side by the pushing of the knock body 5a. And a cam mechanism 5b that holds the pen tip 3 connected to the resin pipe 4 in a state of protruding from the base 2. When the knock body 5a is pushed, the nib tip 3 protrudes from the base 2 and when the knock body 5a is pushed again, the nib tip 3 is pulled into the base 2 by the elastic force of the return coil spring 6. Stored.

  The nib tip 3 is made of a soft material such as high-density polyethylene that does not damage the touch panel surface even when a writing operation or a selection / designating operation is performed by bringing it into contact with the touch panel surface. It is formed in the shape of a stepped bar that gradually increases in diameter toward the rear end. Then, the tip of the first stage 3a having the minimum diameter (for example, 2 mm) is processed into a semicircle, the outer diameter of the first stage base part (second stage) 3b is thicker than that of the first stage 3a, and the knock body 5a is pushed. When the nib tip 3 is moved and protrudes from the base 2, the gap between the opening of the base 2 and the nib tip 3 is small, and no play occurs. The outer diameter (thickness) of the second stage 3b can be adapted to the pen axis of the ballpoint pen by setting it to the same outer diameter (2.3 mm) as that of the ballpoint pen tip in the normal ballpoint pen replacement core.

A third stage 3c having a diameter slightly larger than that of the second stage 3b is continuously formed at the rear part of the second stage 3b of the nib tip 3, and a return coil is formed on the rear outer peripheral surface of the third stage 3c. A spring drop-off stop 7 is formed for engaging and holding the spring 6.
The spring drop-off stop 7 includes a spring stop 7a formed in an annular shape on the outer peripheral surface of the rear end of the third step 3c of the nib tip 3, and a position slightly away from the spring stop 7a forward (in the second step). It is comprised with the protrusion 7b which carried out the annular | circular shape and formed in the outer peripheral surface. In addition, the space | interval of the spring stopper 7a and the protrusion 7b is taken as the width | variety which can pinch | pinch and fix the terminal annular part 6a of the coil spring 6 for return.

The nib tip 3 is connected to a resin pipe 4, which is connected via a metal joint fitting 8 as shown in FIG.
The resin pipe 4 uses a polypropylene (PP) pipe that is generally used for replacement of a ballpoint pen. The outer diameter (thickness) of the pipe is the same as that of the replacement of the ballpoint pen, and the length is the pen described above. The length is appropriately changed according to the length of the shaft 1.
The joint fitting 8 is a metal rod (pin), and locking portions 8a that stop moving in the pulling direction when pressed into the pen tip 3 and the resin pipe 4 on both sides in the axial direction. 8b is formed. Further, a stopper ring 8c for restricting the length of insertion into the nib tip 3 and the resin pipe 4 is formed at a substantially central position in the longitudinal direction of the joint metal fitting 8, whereby the nib tip 3 and the resin are formed. Variations in the amount of insertion during press-fitting into the pipe 4 are prevented, and a uniform connection is made possible.
With the above configuration, the connection strength between the nib tip 3 and the resin pipe 4 and the strength against bending can be improved. If the joint fitting 8 built in between the nib tip 3 and the resin pipe 4 is not visible from the outside, a color pipe is used for the resin pipe 4.

With the above configuration, when the knock body 5a is pushed while the nib tip 3 shown in FIG. 1 is immersed in the base 2, the cam mechanism 5b is actuated to return the resin pipe 4 to the return coil spring 6 The first stage 3a of the nib tip 3 is projected from the base 2 as shown in FIG. Thereby, it is possible to input with the tip of the nib tip 3 being in contact with the touch panel surface.
After the input operation is completed, when the knock body 5a is pushed again, the cam mechanism 5b is actuated so that the pen shaft 1 and the cam mechanism 5b are not latched, and the elastic force of the return coil spring 6 is used. The nib tip 3 is pushed up. Thereby, the resin pipe 4 to which the nib tip 3 is connected is also moved, and the first stage 3a of the nib tip 3 is drawn into the base 2 and returns to the state shown in FIG. Thereby, when the touch pen is not used, the nib tip 3 can be protected by making the state shown in FIG.
Furthermore, by changing the length of the resin pipe connected to the nib tip 3, it is possible to easily cope with pen shafts of various standards.

In the above-described embodiment, the head knock type is shown as the knock type steering mechanism. However, the pen piece 1 is provided with an operation piece that slides along the axial direction of the pen shaft on the rear outer peripheral surface (side surface) of the pen shaft 1. It is also possible to use a knock type.
Further, the pen shaft 1 may be provided with a clip on the outer peripheral surface of the rear part so as to be hooked in a pocket of clothes.
