A solid cylinder, the outer rim of cylinder bottom is equipped with chimb, and chimb has the extension portion of a fixed light mark controller, and the bottom of cylinder is set as an arc root edge face, and arc root edge face and chimb keep a potential difference gap;

A plurality of projection shape contacts are located on the cylinder arc root edge face, correspond respectively to the electric contact on the relative position of keyboard case internal circuit board surface, projection shape contact symmetric offset spread becomes two concentric circless, and it is one group with four contacts wherein, on the formation, upper right, right, the bottom right, down, the lower-left, a left side, group such as eight cursor movement directions such as upper left grade, utilize the vertical parallax of each contact of each direction of motion group, with the cursor control direction of exerting pressure is varied in size with exerting pressure, the different directions on the turning circuit plate and the electric contact of varying number are to change cursor movement direction and high and low speedization.

This cursor control can be installed on the mobile computer.

Reaching embodiment in conjunction with the accompanying drawings is described in detail as follows architectural feature of the present utility model:

Description of drawings:

Fig. 1: the utility model is installed in an embodiment synoptic diagram on the keyboard;

Fig. 2: the inverted stereographic map of cursor control of the present utility model;

Fig. 3: the cut-open view of cursor control of the present utility model and its base circuit board;

Fig. 4: the backplan of cursor control of the present utility model.

As shown in Figure 1, cursor control 20 of the present utility model is located on the appropriate location of computer keyboard 10, is used to control the direction of motion and the high and low speedization of cursor.

Shown in Fig. 2,3, cursor control 20 is a column, comprise a solid cylinder 21, the bottom outer rim ring of cylinder 21 is established chimb 22, chimb 22 has an extension portion 23, utilize extension portion 23 cursor control 20 can be fixed on the enclosure interior of computer keyboard 10, and cylinder 21 can be protruded out out from the surface of shell of keyboard 10, as shown in Figure 1.

The bottom of cylinder 21 is set as an arc root edge face 24, and makes the chimb 22 of arc root edge face 24 keep a potential difference gap; Be provided with a plurality of projection shape contacts 25 on arc root edge face 24, each projection shape contact 25 corresponds respectively to the electric contact 12 on the circuit board 11 surperficial relative positions of keyboard 10 enclosure interior, as shown in Figure 3; When cursor control 20 is installed in keyboard 10 inside, just can be by the outer rim chimb 22 contact circuit plates 11 of cylinder 21, and utilize the potential difference gap of arc root edge face 24 and chimb 22, be provided as the space of pushing of cursor control 20.

As shown in Figure 4, among the embodiment of the present utility model, each projection shape contact 25, be located on the arc root edge face 24 of cursor control 20, symmetric offset spread becomes two concentric circless, and be one group with four projection shape contacts 25 wherein, on the formation, upper right, right, bottom right, down, lower-left, a left side, eight cursor movement direction groups such as upper left; Utilize the vertical parallax of each projection shape contact 25 of each direction of motion group, can be according to the operator to the direction of exerting pressure of this cursor control 20 and the size of exerting pressure, and the electric contact 12 of different directions on the turning circuit plate 11 and varying number reaches the operation that changes cursor direction and cursor high and low speedization.
