Abstract

The invention relates to a tracking ball device to control the movement of cursor. It comprises main body, hold trough, track ball, and plural sensing components. The hold trough is set in the main body; track ball is set in the hold trough to control the movement of the cursor. Sensing components is set in the through surrounding the track ball to sense the pressing direction. When the track ball is rolling and the sensing component is pressed to a certain direction, the cursor would move toward the direction. Thus, it would be operated by the simple method and using the least hand section, and the cursor would move to the aimed location in a short time.

Description

Track-ball structure

Technical field

The present invention relates to a kind of track-ball structure, be applied to have the mouse or the locating device of trace ball, with the position of control cursor on computer screen.

Background technology

Import mouse behind market from Apple Computer in 1984, mouse just becomes when controlling personal computer, an indispensable input media.Since the shape of mouse and be connected with electric wire, so an outward appearance picture mouse, and be called as mouse.

General mouse is provided with the trace ball that a part exposes, in the application of force during with the rolling track ball, inner two disks of right angle orientation each other of mouse, just can follow trace ball to rotate, at the same time, through optical detection, can make the rotating speed of two disks convert displacement on the rectangular coordinate to, therefore connect the electronic device of mouse, the cursor on its screen just can relatively move to destination locations from reference position.But such mouse, its force mechanism are to be axle with the wrist, do the action of rolling mouse, so under long-term the use, cause easily aching, wrist are damaged.

Certainly, for working morphology and the computed custom that satisfies various users, also constantly bring forth new ideas in the design of mouse and improve, so the mouse that development is so far come out, its product item is numerous, and respectively has difference in functionality and characteristic.

" the 3rd structure-improved of mouse " as TaiWan, China patent announcement number No. 364640 patent case, " structural improvement of optics track-ball structure " of No. 486121 patent case, the technology that " mouse of two direction moving window scroll bars simultaneously " of No. 511749 patent case and " Palm mouse " of No. 547724 patent case are disclosed, no matter these patent cases are employed to be optical profile type structure or mechanical structure, main all is to be generally positioned at the trace ball of mouse body bottom, change and be arranged at above the mouse body, so can the finger roll trace ball, moving cursor, even provide other function, thereby can solve general mouse effectively and move the time, the situation of desk-top space deficiency, and be difficult for the desktop dust is brought to mouse inside, but still be must be to point rolling track ball constantly, and make cursor move to destination locations from reference position, though it is easy to use, under long-term the use, also be to cause easily aching, and the finger base portion is damaged.

Moreover, though develop the technology that with rocking bar control cursor afterwards, with under the situation of rolling track ball constantly, promote rocking bar can moving cursor to destination locations, but rocking bar is being pushed, and after discharging, the restoring force that it recenters can make the finger that promotes rocking bar bear pressure, in case rocking bar decentering position is far away more, the pressure that finger is born can be big more, so long-time the use down caused aching of finger easily.

Summary of the invention

Fundamental purpose of the present invention is provides a kind of track-ball structure, in the mode of simplifying and utilize minimum hand position to control, and meets ergonomics, and at short notice moving cursor to destination locations.

According to disclosed track-ball structure, in order to moving of control cursor, this track-ball structure includes body, storage tank, trace ball and a plurality of sensing component, wherein storage tank is arranged at body, the outer open country of trace ball part is placed in the storage tank, with moving of control cursor, then around trace ball, be laid in the storage tank as for sensing component, in order to sensing pressurized direction, in the trace ball rolling and constantly when a direction presses on sensing component, cursor is moved to aforementioned direction constantly, and when discharging trace ball, cursor just can stop to move, so the mode that can simplify and utilize minimum hand position to control, and meet ergonomics, and at short notice moving cursor to destination locations.

For making purpose of the present invention, structural attitude and function thereof are had further understanding, conjunction with figs. is described in detail as follows now.
