Abstract

PURPOSE:To output the signals only in a period when a switch is kept turned on and to the undesired position error of a cursor by containing the switch into the cursor of a data tablet and connecting the switch in series to a signal line led from a signal generating part. CONSTITUTION:A switch is turned on when a hand touches a touch sensing part 2. Then the signal of a signal generating part 1 is transmitted to the main body of a tablet TABLET via a signal line 4 only when a cursor CURSOR is operated by a hand. Thus, the coordinate signals are continuously outputted from a data tablet at the final operation even though the cursor has a position error when it is not operated.

Description

【発明の詳細な説明】 〔産業上の利用分野〕 本発明は、データ・タブレットに関し、特に位置の指定
に使用するカーサ−に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a data tablet, and more particularly to a cursor used for specifying a position.

〔従来の技術〕[Conventional technology]

通常、カーサ−の出力する座標信号をスクリーン上の１
点に嘗き換えてカーサ−の動きをスクリーン上で目視し
て利用することが多い。従来カーサ−は絶えず座標信号
を出力していた。Normally, the coordinate signal output by the cursor is
It is often used by visually observing the movement of a cursor on a screen instead of a dot. Conventional cursors constantly output coordinate signals.

〔発明が解決しようとする課題〕[Problem to be solved by the invention]

つまりカーサ−から手を離した状態においても座標信号
は出力されつづけており、キーボード操作等のわずかな
振動によって位置がずれてしまうことが応々にしてあっ
た。In other words, the coordinate signal continues to be output even when the hand is removed from the cursor, and the position may sometimes shift due to slight vibrations caused by keyboard operation or the like.

〔課題を解決するための手段〕[Means to solve the problem]

本発明のデータ・タブレットは信号の出力を制御するス
イッチをカーサ−内に有している。The data tablet of the present invention has a switch within the cursor that controls the output of the signal.

〔実施例〕〔Example〕

次に本発明について図面を参照して説明する。 Next, the present invention will be explained with reference to the drawings.

信号が出力されつづけることになる。FIG. 1 shows an embodiment of the present invention. By setting the switch (3) to turn ON only when the contact sensing part (2) is touched, you can use the cursor (CUR8OR) by hand.
The signal from the signal generator (1) is transmitted to the tablet main body (TABLET) through the signal line (4) only when the tablet is being operated. As a result, even if the position of the cursor is shifted other than when the cursor is operated, the data tablet continues to output the coordinate signal at the time of the last operation.

れる。FIG. 2 shows a second embodiment of the invention. Photoelectric element (7)
While the light is shining on the switch (8), the switch (8) is turned on.When the light is cut off, the switch (8) is turned on. As a result, a signal is output only during the period when the small hole (6) on the side surface of the cursor is covered with a finger, and the same effect as in the first embodiment can be obtained.

〔発明の効果〕〔Effect of the invention〕

のみ信号を出力するようにでき、意図しないカーサ−の
位置ずれを防ぐことができる。As explained above, the present invention has a built-in switch in the cursor of a data tablet and connects it in series with the signal line from the signal generator so that a signal is output only when the cursor is operated by hand. This can prevent unintentional displacement of the cursor.
