Description

The present invention relates to a pointing device input device for a notebook computer.

Currently, notebook computers are used for spreadsheets, e-mail creation, document creation, etc., and are used as support tools for salesmen and as tools for effective use of limited desk space for businessmen.
In many of these notebook computers, a touch pad disposed on the front surface of the notebook computer is used as a pointing device without connecting a mouse. The touchpad is utilized especially for businessmen who frequently travel and go out.
This invention is a technology related to input devices that seek to improve the operability of touchpads.

の座標位置の変化を演算し、カーソル位置を移動させ、タッチパッドの周辺部に配置された右と左クリックを操作する事によりデスクトップパソコンに於けるマウスの基本操作を代行する。
タッチパッドセンサーは、モバイルツールとしての携帯性の実現の為、名刺又はやや大きいサイズである事から、液晶画面の左下角から右上角へカーソルを大きく移動する場合は、タッチパッドの左下角から右上角へ指で何回かパッドをタッチし指を移動させ離す作業を数回繰り返す必要があり、簡便とは言えない。
ノートパソコンの機種によっては、一定のタッチパッド上の指の移動量をより大きいカーソルの移動量に変換する様に環境設定が可能なシステムを採用している機種もある。この環境設定変更により、同じタッチパッド上の移動量を、より大きな移動に変換する事が可能です。しかしこの場合、カーソルの動き全体が大きく移動が粗くなり、微妙な細かいパッド上の指移動も比較的大きなカーソル移動に演算され、細かいカーソル移動には不向きとなる。
一方、タッチパッドの環境設定を細かい通常の使用環境にした状態の場合は、大きなカーソル移動を行う場合、何回か指でタッチし移動させ離す作業をする必要があり面倒である。また現在の大半のノートパソコンでは、同様の操作にてマウスの縦や横スクロールをタッチパッド操作にて実現できる機種がある。しかしこの場合も、大きいスクロールをする場合は、何回か指でタッチパッド上でタッチし移動させ離す作業を繰り返す必要があり、スクロールホイールを内蔵したマウスにの様にスマートな作業とは言えない。
よりスマートに短いパッド上の指移動操作にて、大きいカーソル移動と小さいカーソル移動を使い分け、大きい画面スクロールと小さい画面スクロールを使い分ける使い勝手に優れた利便性がノートパソコン等のモバイルツールに於いて求められている。Currently, a touch pad is touched on the pad with a finger by a user, the finger is moved, and the movement amount is detected by a capacitance touch pad sensor and a scanning control detection I / F circuit.

The change of the coordinate position is calculated, the cursor position is moved, and the right and left clicks arranged on the periphery of the touchpad are operated to perform basic mouse operations on the desktop personal computer.
The touchpad sensor is a business card or a slightly larger size to realize portability as a mobile tool, so when moving the cursor from the lower left corner of the LCD screen to the upper right corner, Since it is necessary to repeat the work of touching the pad several times with the finger to the corner and moving the finger to release it several times, it is not convenient.
Depending on the model of the notebook computer, there is also a model that adopts a system in which an environment can be set so as to convert a finger movement amount on a certain touch pad into a larger cursor movement amount. By changing this environment setting, the amount of movement on the same touchpad can be converted to a larger movement. However, in this case, the entire movement of the cursor is large and the movement is rough, and the delicate movement of the finger on the fine pad is also calculated as a relatively large movement of the cursor, making it unsuitable for fine cursor movement.
On the other hand, in a state where the environment setting of the touchpad is set to a fine normal usage environment, when moving a large cursor, it is troublesome because it is necessary to touch and move it with a finger several times and move it away. In addition, most current notebook PCs have a model that can perform vertical and horizontal scrolling of the mouse by touchpad operation by the same operation. However, in this case as well, when scrolling large, it is necessary to repeat the work of touching and moving the finger pad on the touchpad several times, and it is not as smart as a mouse with a built-in scroll wheel. .
Mobile tools such as laptop computers are required to be more convenient and convenient to use large and small cursors by using a finger movement operation on a short pad. ing.

The present invention is a capacitance sensor for detecting information on positional variables on the x-axis and positional variables on the y-axis as the finger moves on the touch pad, sensor scanning control circuit in the vertical and horizontal directions, and detecting the coordinate position. In a touch panel input device for a notebook personal computer comprising a control information processing I / F circuit including right and left click buttons and a control information processing I / F circuit including a coordinate position information transmission circuit to a CPU, a storage circuit, a movement amount variable circuit, and a position in front of the personal computer By installing a lever that slides or rotates in the right direction and a movement amount switching circuit installed on the PC, the cursor movement amount and scroll movement amount can be freely changed by lever operation without changing the central environment setting. It is what you do.
The lever is marked with bar information for optically detecting the lever position, and two levers of reflective photointerrupters with different phases are combined to detect the lever position by optical means.
When the finger is released from the lever, a lever is installed that returns to the normal neutral position by the spring provided.
Furthermore, at the neutral position at the left end of the lever, the finger movement of a certain distance on the touchpad is converted into a small cursor movement, and the lever is pressed in the right direction with the left hand and moved in multiple stages. It has a built-in movement variable circuit that counts a larger cursor movement depending on the position.
For this reason, if you want to move the cursor greatly, move the finger on the touchpad while pushing the lever all the way to the right to move the cursor. If you want to move the cursor finely immediately after that, you can return the lever to the left end with your left hand and convert it to a smaller amount of movement to make a delicate detection. In addition, when the lever is returned to an intermediate position, an intermediate amount of cursor movement can be detected.
Users who do not use large cursor movements should use the lever in the neutral position.
Furthermore, notebook computers are also used for document creation, HP browsing, spreadsheets, etc. When scrolling the screen down or left and right, operating the lever of the present invention, the finger scrolling instructions are given on the touchpad. By moving, the large scroll amount, medium scroll amount, and fine scroll amount can be freely controlled by operating one lever without changing the environment settings.
Furthermore, in a notebook PC with a structure in which a part of the scroll wheel rotating body 23 is arranged around the touch pad, the amount of movement of the encoder pulse can be varied according to the slide position of the lever, improving convenience.

The touchpad of the present invention allows the user to freely change the amount of large scroll movement, small scroll movement, and intermediate movement by lever operation without changing the environment settings. At the same time, the amount of movement of the cursor by finger movement on a certain touchpad is also controlled in multiple steps by lever operation.
This is very useful when you want to browse the last page of a long HP or sentence quickly. A sliding or rotating lever that moves to the left or right located around the touchpad of the notebook computer of the present invention enables switching control between large cursor movement, subtle cursor movement, and intermediate movement.

Describes the best mode for realizing the present invention. The present invention has a lever that slides or rotates in a straight line, and controls the position of the lever while moving the finger on the touch pad to freely move the cursor and scroll horizontally and vertically. It is intended to support the salesman as a mobile tool while moving or moving in an environment where control and a wheel mouse cannot be connected.

Fig. 2 A specific example of the touchpad input device will be described. The touchpad input device of the present invention controls the amount of vertical and horizontal scrolling and the amount of cursor movement by moving the finger on the touchpad in an arbitrary trajectory while operating a rotary or sliding lever. It enables smart and speedy movement while switching.
