BACKGROUND OF THE INVENTION
The present invention relates to cursor control mechanisms, and more particularly to such a cursor control mechanism designed for controlling the amount and direction of movement of a cursor on a display screen in three dimensions. The control mechanism can be made in a mechanical type, or an optical type.
Regular cursor control mice are commonly comprised of a housing holding a track ball. When the track ball is moved on a flat surface, the moving amount and direction of the track bail is detected by a control circuit. and converted into a corresponding output signal for controlling the movement of a cursor on a display screen. However. the control circuit of regular cursor control mice can only detect the movement signal on a plane in X-axis and
Y-axis directions, i.e., it cannot detect a movement in Z-axis.
SUMMARY OF THE INVENTION
The present invention has been accomplished under the circumstances in view. It is the major object of the present invention to provide a cursor control mechanism which controls the movement of a cursor on a display screen in Z-axis. According to one embodiment of the present invention, the Z-axis cursor control mechanism comprises a Z-axis driving wheel mounted in a holder frame inside the housing of a mouse and partially projecting out of the housing for turning by hand, a transparent grid wheel coupled to the Z-axis driving wheel and having a plurality of transverse teeth and a plurality of gaps alternatively spaced around the periphery, a light source for example a light emitting diode controlled to emit light through the transparent grid wheel, and a photo sensor for example a photo transistor adapted for receiving refracted light from the transparent grid wheel and converting it into an output signal corresponding to the moving direction and angle of the Z-axis driving wheel for controlling the amount and direction of movement of a cursor on a display screen.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
Referring to Figures from 1 to 3, a Z-axis cursor control mechanism of a mouse in accordance with one embodiment of the present invention, is generally comprised of a grid wheel 1, a housing 2, a plurality of metal spring strips 3, 4, 5, and a Z-axis driving wheel 6.
The grid wheel 1 comprises a center hole 10, two annular center conductive elements 12 symmetrically disposed at two opposite sides around the center hole 10, three equiangularly spaced through holes 121 connected between the annular center conductive elements 12, and two grids 11 disposed at two opposite sides around the annular center conductive elements 12. Each grid 11 comprises a plurality of conductive portions 111 and insulative portions 112 alternatively arranged around one annular center conductive element 12. There is an angular difference between the two grids 11. The annular center conductive elements 12 are electrically connected to- the conductive portions 111 of the grids 11. The through holes 121 are coated with electrically conductive material to electrically connect the annular center conductive elements 12.
The housing 2 comprises a holder frame 21 having a coupling notch 222, a supporting frame 22 suspended above the holder frame 21 and having a coupling notch 221 in vertical alignment with the coupling notch 222 of the holder frame 21, a first receptacle 23 raised from the holder frame 21 and defining two parallel plug holes 231 adapted for holding the metal spring strips 3, 4, and a second receptacle 24 raised from the holder frame 21 and defining a plug hole 241 adapted for holding the metal spring strip 5. The metal contact spring strips 3, 4 are respectively mounted in the plug holes 231 of the first receptacle 23, and disposed in contact with one grid 11 and one annular center conductive element 12. The metal spring strip 5 has one end plugged into the plug hole 241 of the second receptacle 24, and an opposite end disposed in contact with one grid 11.
The grid wheel 1 and the Z-axis driving wheel 6 are coupled together and mounted in the coupling notches 221, 222 between the holder frame 21 and the supporting frame 22.
The Z-axis driving wheel 6 comprises a first wheel shaft 61 and a second wheel shaft 62 respectively raised from two opposite sides at the center. The first wheel shaft 61 is coupled to the coupling notch 221 of the supporting frame 22. The second wheel shaft 62 is fitted into the center hole 1 of the grid wheel 1 and then coupled to the coupling notch 222 of the holder frame 21. When the Z-axis driving wheel 6 is turned, the grid wheel 1 is synchronously turned with the Z-axis driving wheel 6.
When the Z-axis driving wheel 6 is turned, the grid wheel 1 receives power supply from one or more of the metal strips 3,4,5, the metal spring strips 3, 5 are moved over the conductive portions 111 and insulative portions 112 alternatively and provide a respective output signal of a variable voltage. Therefore, the output signal
from the grid wheel 1 controls the amount and direction of movement of the cursor on the display screen.
Figures 4 and 5 show an alternate form of the present invention. A Z-axis cursor control mechanism according to this alternate form, comprises a transparent grid wheel 1, a housing 2, a
Z-axis driving wheel 6, a light source 7, and a photo sensor (for example a phototransistor) 8. The housing 2 comprises a holder frame 21 having a coupling notch 222, and a supporting frame 22 suspended above the holder frame 21 and having a coupling notch 221 in vertical alignment with the coupling notch 222 of the holder frame 21. The transparent grid wheel 1 and the Z-axis driving wheel 6 are coupled together and mounted in the coupling notches 221, 222 between the holder frame 21 and the supporting frame 22.
The transparent grid wheel 1 comprises a center hole 10. a plurality of transverse teeth 15 and a plurality of gaps 151 alternatively spaced around the periphery. The light source 7 and the photo sensor 8 are respectively disposed adjacent to the transparent grid wheel 1 at different angles. Light from the light source 7 passes through the transparent grid wheel 1, and detected bv the photo sensor 8. The photo sensor 8 has an output end connected to an amplifier circuit (not shown). By means of calculating the order and frequency of the output signal from the photo sensor 8. the moving direction and angle of the transparent grid wheel 1 is judged. The Z-axis driving wheel 6 comprises a first wheel shaft 61 and a second wheel shaft 62 respectively raised from two opposite sides at the center. The first wheel shaft 61 is coupled to the coupling notch 221 of the supporting frame 22. The second wheel shaft 62 is fitted into the center hole 10 of the grid wheel 1 and then coupled to the coupling notch 222 of the holder frame 21.
When the Z-axis driving wheel 6 is turned, the grid wheel 1 is synchronously turned with the Z-axis driving wheel 6, and light from the light source 7 is refracted by the transparent grid wheel 1 and detected by the photo sensor 8. When the photo sensor 8 is alternatively turned on and off when light from the light source 7 passes through the gaps 151 and the teeth 15, and the variation of light is converted into a corresponding electric signal. Therefore, the photo sensor 8 provides an output signal to control the amount and direction of movement of the cursor on the display screen subject to the moving amount and angle of the Z-axis driving wheel 6.
Figure 6 shows another alternate form of the Z-axis cursor control mechanism. According to this alternate form, the holder frame 21 has an axle hole 224, the supporting frame 22 has an axle hole 223. The axle holes 2237 224 are not vertically aligned. The Z-axis driving wheel 6 has a wheel shaft 61 raised from one side at the center and mounted in the axle hole 223 of the supporting frame 22, and a gear 63 disposed at an opposite side.
The grid wheel 1 has a gear 13 disposed at one side and meshed with the gear 63 of the Z-axis driving wheel 6, and a wheel shaft 14 disposed at an opposite side and mounted in the axle hole 224 of the holder frame 21. When the Z-axis driving wheel 6 is rotated, the grid wheel 1 is turned by the gear 63 of the Z-axis driving wheel 6 to let light of the light source 7 pass and to refract light of the light source 7 alternatively, thereby causing the photo sensor 8 to provide a corresponding signal output for controlling the amount and direction of movement of the cursor on the display screen.
Figure 7 shows still another alternate form of the present invention. According to this alternate form, the holder frame 21 has an axle hole 224, the supporting frame 22 has an axle hole 223.
The axle holes 223, 224 are not vertically aligned. The Z-axis driving wheel 6 has a wheel shaft 61 raised from one side at the center and mounted in the axle hole 223 of the supporting frame 22, and a friction wheel 64 disposed at an opposite side. The grid wheel 1 has a friction wheel 15 disposed at one side and peripherally engaged with the friction wheel 64 of the Z-axis driving wheel 6, and a wheel shaft 14 disposed at an opposite side and mounted in the axle hole 224 of the holder frame 21. When the Z-axis driving wheel 6 is rotated, the grid wheel 1 is turned by
the friction wheel 64 of the Z-axis driving wheel 6 to let light of the
light source 7 pass and to refract light of the light source 7
alternatively, thereby causing the photo sensor 8 to provide a
corresponding signal output for controlling the amount and direction of movement of the cursor on the display screen.
Referring to Figures 8 and 9, the Z-axis driving wheel 6 can be mounted in a vertical position as shown in Figure 8, or a horizontal position as shown in Figure 9.
It is to be understood that the drawings are designed for purposes of illustration only, and are not intended as a definition of the limits and scope of the invention disclosed.
