In addition, in the relevant Z encode axis module, mainly can be divided into optical profile type (promptly shown in the content among the TW399754 of Taiwan), with mechanical coding structure (promptly as the content among the TW461548 as described in); No matter and which kind of the structure of Z encode axis change for, all be easy to use advantage of the present utility model behind the conversion correspondence position.

The embodiment of major technique of the present utility model is described as follows:

At first see also Fig. 3, Fig. 4, the pointer operation device has a base 40 and the loam cake 41 that covers base 40, and the leading portion of close loam cake 41 then is an operational zone 42, and the designed operational module of the utility model just is configured in this, in first kind of embodiment of the present utility model, operational module includes:

Several key zones are that a kind of design of two key formulas is respectively two key zones such as left key area L (is example with dexterous pattern) and right button district R, and left key area L does not wherein have any button, only have a perforate 50 that penetrates loam cake 41; Right button district R then includes the button 51 that an end is suspended to loam cake 41, with the right button switch module 52 (switch element) that is positioned at button 51 belows and can touches for it; As for also having a left button switch module 53 below left key area L, left button switch module 53 all is installed on the circuit board 60 with right button switch module 52, and each switch module 52,53 is an exportable coded signal being subjected to that external force exerts pressure after starting.

One Z encode axis module (this coding module of sentencing optical profile type illustrates) includes: a roller 70, have a wheel shaft 71, and also have several perforation 72 at its disk, and wheel face 701 and expose from perforate 50 places of left key area L; That is, roller 70 is set at a corner of operational zone 42.

And, one carrier 80, has a support frame 81, (total a pair of with the axle bed 82 that is fixed on support frame 81, among the figure rarely seen one of them), axle bed 82 can be pivoted for the wheel shaft 71 of roller 70 and rotate freely, and support frame 81 has at least a part to drop on the compression zone 531 of (placing) left button switch module 53; And also have a pivot 83 at an end of carrier 80.
