JPS583143Y2 - Wireless data entry pen - Google Patents

Description

[Detailed description of the invention] The present invention is a wireless type data input device applied to a data input device that converts arbitrarily specified characters, symbols, etc. on a tablet into electrical signals as detailed in Japanese Patent Application No. 51-94049. Regarding data entry pens.

The purpose of the present invention is to provide a long-life, highly reliable, compact, and convenient input pen that is compatible with the wireless data input pen detailed in Japanese Patent Application No. 51-94049.

According to the present invention, a coil 12 made of a non-magnetic conductor is wound around the outer periphery of a pen tip 11 made of a magnetic material, and one end of the coil 12 is connected to the pen tip portion covered with a coating 10 of synthetic resin or the like. The contact piece 6 or the contact piece 5' provided on the contact piece 5' is connected to the contact piece 5 connected to the other end of the coil 12, and the contact piece γ is provided facing each other, and the contact piece 5 and the contact piece 6 or the contact piece 5' a holding member 4 that holds the pen nib and the holding member 4 so that they are always biased through contacts γ and γ'; a sliding member 3 that slides inside the pen shaft 1; A hole 2b which is screwed onto the pen barrel 1, into which a plurality of stopper shafts 8 fixed to the protrusion 2a button and the holding member 4 can fit and slide, and which has a depth that regulates the amount of sliding of the stopper shaft 8; Pen barrel 2 with
an elastic member 9 located between the pen shaft 2 and the sliding member 3 and urging the sliding member 3 toward the opening of the pen shaft 1; and an adjustment nut screwed onto the pen shaft 2. A wireless data input pen consisting of 13 is obtained.

Next, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a partial sectional view showing a first embodiment of the present invention, in which a coil 12 made of a non-magnetic conductor such as enameled wire is wound around a pen tip 11 made of a magnetic material such as ferrite. In order to prevent damage to the tablet surface when the protective button and pen tip of the coil 12 are pressed against the tablet surface, a coating 10 of synthetic resin or the like is applied by means such as casting, molding, or painting.

The holding member 4 holds a fixed contact piece 6 with a contact T, and a movable contact piece 5, which also has a contact γ' and faces the fixed contact piece 6 and is biased. The coil 12 is electrically connected by soldering or the like.

In addition, the holding member 4 is provided with a pen that regulates the stroke amount A of the pen tip.
In addition, a plurality of stopper shafts 8 are fixed so that the surface of the movable contact piece 5 and the slope of the protruding portion 2a of the pen shaft 2, which will be described later, can always be mounted at opposing positions.

The pen tip and the contact portion configured as described above are fixed to both ends of the sliding member 30, and are slidably fitted into the inside of the pen shaft 1 made of a non-magnetic material, and are brought into contact with the pen tip. The elastic member 9 is inserted so that the sliding part consisting of the child part is urged against the tip of the pen shaft 1.

Note that the vicinity of the inner tip of the pen barrel 1 has a heavier shape than the sliding portion.

Next, the pen shaft 2 with the adjusting nut 13 screwed thereon is screwed onto the pen shaft 1.

The pen shaft 2 has a projection 2a having an inclined surface and a hole 2b having a predetermined depth. When the pen is pressed against the tablet surface during operation, the sliding part moves and the movable contact piece 5 moves. Pushed by the slope, the contacts 7 are separated and the coil 12, which had been maintaining an electrically closed circuit, is opened.

Also, the amount of movement of the sliding part is A due to the hole 2b of the pen shaft 2.
limited to.

This amount of movement A can be adjusted to a length that meets the operator's requirements by loosening the adjustment nut 13 and adjusting the threaded portion between the pen shaft 2 and the pen shaft 1.
By tightening the pen to the pen shaft 1, it is possible to maintain the movement tA without loosening due to the double nut effect.

FIG. 2 is a partial view showing a second embodiment of only the contact portion, in which both the contact piece 5 and the contact piece 5' are movable, and the protrusion 2 a' of the pen shaft 2 is conical. The same effect as the first embodiment can also be obtained.

As explained above, the present invention achieves long life and high reliability by integrating the pen tip and the contact part, can be downsized, and can easily adjust the stroke amount to suit the operator. can.

This has the effect of obtaining the structure of a wireless data input pen.
