【発明の詳細な説明】本発明は筆記動作をすると同時にその筆記ストロークを
電気信号に変換し、文字等の情報を入力する装置に関す
るものである。
DETAILED DESCRIPTION OF THE PRESENT EMBODIMENTS The present invention relates to a device for inputting information such as characters by converting handwritten strokes into electrical signals simultaneously with the handwritten strokes.

この種の入力装置を第1図に示す。An input device of this type is shown in FIG.

1はペンの.外筐、2a,2b,2c,2dはそれぞれ
ペンの内壁に設けた感圧素子、3は外筐1の先端の狭持
部4で支持された芯軸で、シャープペンシルあるいはボ
ールペンの芯軸のような構造となっている。
Reference numeral 1 denotes the outer casing of the pen, 2a, 2b, 2c, and 2d denote pressure-sensitive elements provided on the inner wall of the pen, and 3 denotes a core shaft supported by a clamping portion 4 at the tip of the outer casing 1, and has a structure similar to that of a core shaft of a mechanical pencil or ballpoint pen.

紙にこの装置を用いて筆記すると、芯軸3の尖端が紙と
の摩擦により反作用を受けて外筐1の狭持部4を支点と
して感圧素子2a,2b,2c,2d、にストローク圧
を伝達する。
When writing on paper using this device, the tip of the core shaft 3 receives a reaction due to friction with the paper, and transmits a stroke pressure to the pressure-sensitive elements 2a, 2b, 2c, and 2d with the clamping portion 4 of the outer casing 1 as a fulcrum.

例えば、第1図イの平面図に示す様な方向eに筆記する
と感圧素子2dに圧力が加わり、fの方向に筆記すると
、2aに圧力が加わる。
For example, when writing in the direction e as shown in the plan view of FIG. 1A, pressure is applied to the pressure-sensitive element 2d, and when writing in the direction f, pressure is applied to 2a.

感圧素子2cを上にし2dを手前にしてペン(入力装置
)を持ち、第2図に示す様な書き方で数字を筆記すると
、各々の感圧素子は図示された順序で圧力を受ける。
When the pen (input device) is held with the pressure-sensitive element 2c on top and 2d in front and numbers are written as shown in FIG. 2, each pressure-sensitive element receives pressure in the order shown.

たとえば数字「2」の場合、最初は感圧素子2aが圧力
を受け、続いて2d,続いて2b,2aの順に圧力を受
ける。
For example, in the case of the number "2", pressure is first applied to the pressure sensitive element 2a, followed by 2d, then 2b, and then 2a.

このようにして数字を筆記すれば、圧力を受ける感圧素
子の配列は各数字ごとに異なる。
When numbers are written in this manner, the arrangement of pressure-sensitive elements that receive pressure is different for each number.

なお第2図中の点Sは筆記する際の始点である。Incidentally, point S in FIG. 2 is the starting point when writing.

なお、第2図は一例であり、実際には4つの感圧素子に
より8方向の成分による配列を調べて認識される。
Note that FIG. 2 is just an example, and in reality, the arrangement of components in eight directions is examined and recognized using four pressure-sensitive elements.

しかしこのような装置では芯軸3の尖端を支点にして、
ペンにある方向の圧力を与えると芯軸3の他端は動き、
感圧素子は電気量を発生する。
However, in such a device, the tip of the core shaft 3 is used as a fulcrum,
When pressure is applied to the pen in a certain direction, the other end of the core 3 moves.
The pressure sensitive element generates an electrical quantity.

この場合芯軸3の尖端は動いていない。In this case, the tip of the core 3 does not move.

すなわち文字は書かれてないのに感圧素子に電気量が現
らわれることになる。
In other words, even though no characters are written, an electrical charge appears in the pressure-sensitive element.

これは故意にしなくても、文字の書き始め又は、書き終
りによく起る。
This often happens unintentionally at the beginning or end of a letter.

また文字の屈折点(第3図kの部分)においても発生す
る。
It also occurs at the inflection points of characters (part k in Figure 3).

これらの場合の感圧素子の電気量は不必要であり従来は
この情報をを識別しないで入力していたため、誤認識が
生じることがあった。
In these cases, the electrical charge of the pressure-sensitive element is unnecessary, and in the past, this information was input without being identified, which sometimes resulted in erroneous recognition.

本発明はこのような欠点を除去しようとするもので、以
下にその実施例について説明する。
The present invention is intended to eliminate such drawbacks, and examples thereof will be described below.

第4図において1,2a,2b,2c,2d,3,4で
示したものは第1図における同符号のものに対応する。
In FIG. 4, the elements designated by the same reference numerals 1, 2a, 2b, 2c, 2d, 3 and 4 correspond to those designated by the same reference numerals in FIG.

異なる点はインク5を収納した芯軸3の先端に球6を設
け、この球は第5図に示すように4極に磁化されている
The difference is that a ball 6 is provided at the tip of a core shaft 3 containing ink 5, and this ball is magnetized into four poles as shown in FIG.

また外筐1の先にはそれぞれx,y,z方向を向いたホ
ール素子などの磁気検出素子7x,7y,7zがけられ
ている。
Further, magnetic detection elements 7x, 7y, and 7z such as Hall elements oriented in the x, y, and z directions are provided at the tip of the outer casing 1, respectively.

紙上にこのペンを用いて筆記すると第1図〜第3図とと
もに述べたと同様な作用により感圧素子は電気力を発生
するが、他方、7x,7y,7zからの電気量も球6が
回転することにより変化する。
When this pen is used to write on paper, the pressure-sensitive element generates an electric force in the same manner as described above with reference to Figs. 1 to 3, but the amount of electricity from 7x, 7y, and 7z also changes as the ball 6 rotates.

ところが球6は第5図に示す様に磁化されているためど
のような方向に回転してもi気検出素子7y,7zのい
ずれかの電気量は変化する。
However, since the ball 6 is magnetized as shown in FIG. 5, the electric quantity of either of the electric detection elements 7y and 7z changes no matter in what direction the ball 6 rotates.

磁気検出素子6x,6y,6zの電気量が変化してない
時は、球6が回転していない時である。
When the electric charge of the magnetic detection elements 6x, 6y, and 6z does not change, the ball 6 is not rotating.

したがって書き始め、書き終り時また文字の屈折点では
球6は回転しない。
Therefore, the ball 6 does not rotate when writing begins, ends, or at the inflection points of the characters.

このように磁気検出素子7x,7y,7zの電気量が変
化している時のみ感圧素子からの情報を出力すれば前述
した様な問題は解消される。
In this way, if information from the pressure sensitive elements is output only when the electric charge of the magnetic detection elements 7x, 7y, 7z is changing, the above-mentioned problems can be solved.

なお磁気検出素子7x,γy,7zの電気量が変化して
いるのを検出するには、それらの素子γx,7y,7z
の電気量をそれぞれ微分の出力の絶対値の内で1つでも
αより大きい時は、感圧素子の情報を出力する。
In order to detect the change in the electric quantity of the magnetic detection elements 7x, γy, and 7z,
When any one of the absolute values of the differential outputs of the electric quantities is greater than α, information of the pressure-sensitive element is output.

ここでαはノイズや、書く時の速さ等を考慮した値であ
る。
Here, α is a value that takes into consideration noise, writing speed, and the like.

また3つの素子7x,7y,7zの出力の微分値がいず
れもαよりも小さい時には感圧素子の情報を出力するの
を停止させる。
When the differential values of the outputs of the three elements 7x, 7y, and 7z are all smaller than α, the output of information from the pressure-sensitive elements is stopped.

上記実施例より明らかなように本発明によれば筆記動作

信号を除去する情報を得ることができるようにしたもの
で、正確な情報の入力を行なうことができる。
As is clear from the above embodiment, the present invention makes it possible to obtain information that eliminates signals that are based on the pressure applied to the core when no writing operation is being performed, thereby enabling accurate information to be input.
