Abstract

A track ball inputting device comprises a shell, a circuit module and a track ball module, wherein the circuit module and the track ball module are arranged in the shell. The track ball module is connected with the circuit module, and the upper half part of a rolling ball of the track ball module is exposed out of an open pore at the upper part of the upper shell. The track ball module is fixedly arranged on the circuit module which is basically parallel to the lower shell, and one end of the circuit module, which is nearer to the track ball module, can move from top to bottom. One end nearer to the track ball module on the circuit module is provided with a first switch, and a flexible assembly is arranged between the lower surface of the end of the circuit module and the lower shell and enables the pressing part of the first switch to be pressed by the upper shell. When the track ball inputting device is used, after moving a cursor to a target location, the track ball module is directly pressed by the finger, and the confirmation operation can be completed. The track ball inputting device has convenient operation, high efficiency, few assembling parts and simple structure.

Description

The trace ball input media

Technical field

The utility model relates to computer entry device, particularly has the input media of trace ball module.

Background technology

The bearing accuracy of track ball mouse and trace ball pointing device is much higher than optical mouse and mechanical mouse.But it needs to use earlier the finger roll spin, cursor in the indicator gate is moved on to the target location, just can finish the location by acknowledgement key then, and the trace ball of track ball mouse in the market and trace ball pointing device only can be controlled moving of cursor, after cursor moves to the target location, finger need be moved on to acknowledgement key, push acknowledgement key and just can finish positioning action, therefore when operation, need moveable finger between trace ball and button continually, inconvenient operation influences operating efficiency.

Summary of the invention

The purpose of this utility model provides a kind of trace ball input media, and this trace ball input media is in when operation, and finger need not leave trace ball can finish positioning action (comprise control cursor move and confirm), and simple in structure, and operation is reliable.

For reaching above-mentioned purpose, the utility model is by the following technical solutions: a kind of trace ball input media, comprise the housing of forming by upper casing and lower casing, be installed on circuit module and trace ball module in the housing, the trace ball module is connected with circuit module and the first half of its spin exposes from the perforate on upper casing top, described trace ball module is installed in above the circuit module, circuit module substantially parallel with lower casing and its can move up and down from the nearer end of trace ball module, from the nearer end of trace ball module first switch is installed above the circuit module, between the following and lower casing of this end of circuit module elastomeric element is installed, the press section of first switch is suppressed by upper casing, make upper casing remove compacting the first switch press portion thereby move down at circuit module when pressing down the spin of trace ball.

The utlity model has following beneficial effect:

After by the trace ball module cursor being moved on to the target location, finger directly clicks the trace ball module can finish the affirmation operation, that is to say, whole positioning action (comprising that the control cursor moves and confirms) only needs a finger just can finish in the quite short time, finger need not leave the trace ball module, easy to operate, the efficient height.

Owing to upwards push away circuit module by elastomeric element, make the press section of first switch be suppressed, so only need just can make when not pushing the trace ball module by the elastomeric element of the appropriate elastic force of design by housing, the press section of first switch can be suppressed reliably by upper casing, thereby can guarantee that operation is reliable.

In addition, its building block is few, and is simple in structure.

Embodiment

With reference to Fig. 1, the utility model is packed in trace ball module 3 above the circuit module 2, on circuit module 2, first switch 4 is installed from trace ball module 3 nearer ends, below circuit module 2 these ends and housing elastomeric element 5 is installed at 1 the end, the press section of first switch 4 is suppressed by upper casing, when when pressing down trace ball 3, circuit module 2 moves down and makes the compacting of upper casing releasing to first switch, 4 press sections, thereby makes first switch, 4 state variation, the output confirmation signal.Like this, after with trace ball module 3 cursor on the display screen being moved on to the target location, finger need not leave trace ball module 3 can confirm operation, makes whole positioning action to be finished quickly and easily by single finger.

Fig. 2 is the vertical view of an embodiment of the utility model, and Fig. 3 is its side view, and Fig. 4 is its structural representation, and Fig. 5 is the structural representation behind the removal housing.

With reference to Fig. 2-5, this trace ball input media comprises housing 1, be installed on circuit module 2 and trace ball module 3 in the housing 1, housing 1 is made up of upper casing 11 and lower casing 12, trace ball module 3 is connected with circuit module 2 and the first half of its spin exposes from the perforate on upper casing 11 tops, so that the user comes the cursor on the control display screen to move by the rolling spin, described trace ball module 3 is installed in above the circuit module 2, circuit module 2 and lower casing 12 substantially parallel and its can move up and down from trace ball module 3 nearer ends, circuit module 2 is top installs first switch 4 from trace ball module 3 nearer ends, circuit module 2 should be installed elastomeric element 5 between the following and lower casing 12 of end, the press section of first switch 4 is suppressed by upper casing 11, when when pressing down the spin of trace ball 3, circuit module 2 moves down the compacting that upper casing 11 is removed first switch, 4 press sections, thereby make first switch, 4 state variation, the output confirmation signal.
