As shown in Figure 3 and Figure 4, under the control of micro computer 52, first and second infrared light-emitting diode 56 and 58 infrared rays that produced can be reflected onto on the cylinder bar 40, and be sent to first and second photoelectric tube 60 and 61, and transmit detection signal in regular turn to micro computer 52 by first and second optical fiber 62 and 64.Therefore, interval as first and second streak line 42 and 44, that is white reflected ray can be replaced by the rotation of cylinder bar 40 and gliding motility, and some of the reflected infrared that detects via first and second photoelectric tube 60 and 61 change, and confirm the moving direction of cylinder bars 40 so that micro computer 52 to be provided.During rotation and gliding motility, the quantity of white or black bar streakline can be substituted the displacement of expression cylinder bar 40, and via micro computer 52 will the positional information of changing into cursor, and by connector 82 will the host computer system that is sent to.Therefore, if cylinder bar 40 laterally slides mobile and need not anyly rotatablely move, then cursor can vertical-right or mobile to the left.On the contrary, if cylinder bar 40 rotation and need not any gliding motility, then cursor can move vertically upward or to the lower end.
The following stated obtains the process of the positional information of cursor via the cylinder bar of indicating device, will be as Fig. 5 to shown in Figure 13.
Please refer to Fig. 5, under the control of micro computer 52, first and second infrared light-emitting diode 56 and 58 infrared rays that produced can be reflected onto on first and second streak line 42 and 44 s' the white line, and by first and second optical fiber 62-1,62-2, with 64-1,64-22 be sent to first and second photoelectric tube 60 and 61, first and second photoelectric tube 60 and 61 can become electronic signal by the conversion receiving infrared-ray, and will be sent in the micro computer 52, to calculate the direction and the displacement of cursor.As shown in the figure, each first and second optical fiber is divided into two optical fiber, and connects first and second photoelectric tube 60 and 61 respectively.
Fig. 6 and Fig. 7 are the swing offset figure of cylinder bar 40, and it is corresponding to a detecting pulse of first and second photoelectric tube 60 and 61.As described previously, article one streakline 42 forms the central axis 46 that is parallel to cylinder bar 40, and label 42-1 as shown in the figure, 42-3, the black line of 42-5 can't reflected infrared.Infrared ray is via the white septal line 42-2 between between the black bar streakline, and 42-4 reflects.First optical fiber 62 by one first and one for the second time optical fiber 62-1 formed with 62-2, its arrangement is perpendicular to central axis 46 and article one streakline 42.The width of each white reflected ray " L " is equivalent to the width " L " of each black bar streakline.The diameter " D " of each optical fiber 62-1 and 62-2 is 2D＜L with the preferable mutual pass of width " L ".If width " L " is much smaller than diameter " D ", then the phase missionary society between infrared ray becomes the suitable control that is not enough to meet cursor.On the contrary, if width " L " much larger than diameter " D ", then the quantity of streak line 42 will reduce, and the accurate control that can't reach cursor movement.If cylinder bar 40 rotates with the direction shown in the 6A figure arrow, and corresponding to first and second photoelectric tube 60 and 61 one the detecting pulse, wherein optical fiber 62-1 is in the face of white reflected ray 42-2, optical fiber 62-2 is in the face of black bar streakline 42-3, then optical fiber 62-1 moves to the position in the face of white reflected ray 42-4, and optical fiber 62-2 moves to the position in the face of black bar streakline 42-5.The position of the cylinder bar 40 of Fig. 6 is rotated to the position of the 68th figure, first and second photoelectric tube 60 and 61 produces respectively corresponding to ultrared one first and one second pulse Ea and Eb, it can obtain via the infrared ray that is reflected in the light emitting diode 56 on article one streakline 42, and is sent to photoelectric tube 60 and 61 by optical fiber 62-1 and 62-2.Because be reflected in the infrared ray on the streak line 42, can be received by two optical fiber 62-1 and 62-2 at different time, differ so between first and second pulse Ea and Eb, have one.Above-mentioned differing in order to confirm the direction of cursor displacement.In other words, be positive number if differ, then cursor displacement meeting arrives the positive dirction of the X-axis on the screen.On the contrary, be negative if differ, then cursor displacement meeting arrives the negative direction of X-axis.Certainly, the displacement of cursor can obtain via the quantity of counting product main pulse Ea or Eb.
Relatively, Fig. 9 and Figure 10 are the displacement diagram that slides of cylinder bar 40, and it is corresponding to a detecting pulse of first and second photoelectric tube 60 and 61.As described previously, the central axis 46 that article one streakline 42 forms perpendicular to cylinder bar 40, and the black line of as shown in the figure label 44-1,44-3,44-5 can't reflected infrared.Infrared ray is via the white septal line 44-2 between between the black bar streakline, and 44-4 reflects.Second optical fiber 64 by one first and one for the second time optical fiber 64-1 and 64-2 formed, it is arranged perpendicular to central axis 46, and parallel with second streakline 44.Another is relevant for the technical description of second streakline, because of it is identical with article one streakline basically, so locate to repeat no more.
Figure 11, Figure 12 are under the control of micro computer 52, via the motion of the cylinder device of detecting indicating device, obtain the flow chart of steps of the positional information of cursor.Please refer to Fig. 4,5,11, in step S200, first and second infrared light-emitting diode 56 or 58 infrared rays that produced can be transferred into cylinder bar 40.Under the control of micro computer 52, light emitting diode 56 and 58 can alternately produce infrared ray.In other words, micro computer 52 makes first light emitting diode 56 produce infrared rays in order to detect the swing offset of cylinder bar 40, and makes second light emitting diode 58 produce infrared rays in order to detect the displacement of sliding of cylinder bar 40.To photoelectric tube 60 and 61, can obtain the alternately time-sharing operation of first and second light emitting diode 56 and 58 via the reflected infrared on the optical fiber transmission cylinder bar 40.Above-mentioned optical fiber can reduce for example quantity of photoelectric tube of required optical element.
In step S210, by first or second optical fiber 62 or 64, can detect the reflected infrared on the cylinder bar 40 via first and second photoelectric tube 60 and 61.In other words, this reflected infrared can be transmitted as two infrared ray Ra and Rb by twice optical fiber of first or second optical fiber.In step S220, this two infrared ray Ra changes standard via first and second photoelectric tube 60 and 61 respectively with Rb and becomes corresponding electronic signal Ea and Eb.In step 5230, this two electronic signals Ea and Eb can analyze via micro computer 52, with direction and the displacement that calculates cursor movement.In step S250, therefore positional information can obtain, and is transferred in the host computer system.In step S260, according to this positional information, the cursor on the mobile display is in X or Y direction at last.
Figure 12 is the direction of calculating cursor movement and the procedure chart of displacement.Direction is via detecting electronic signal Ea and Eb, and is sent in the micro computer 52 by photoelectric tube 60 and 61 and confirms, shown in Fig. 6-8.
In other words, in step S235, if detect differing between between pulse Ea and Eb be one on the occasion of, expression cylinder bar 40 has been substituted in the face of the X of screen or the positive dirction of Y-axis.Certainly, as above Fig. 6-8 description, in the displacement of the cursor of X and Y direction, respectively can sliding and rotatablely moving and obtain via cylinder bar 40.In step S240,, can obtain the displacement of cursor via the quantity of count pulse Ea or Eb.Though the foregoing description illustrates out cursor movement and can only via alternately producing and detect first and second infrared ray, can reach accurate while moving cursor on X and Y-axis at one of two coordinate X and Y.For instance, if first and second light emitting diode 56 and 58 timesharing alternately produce infrared ray first and second streak line in the face of cylinder bar 40, then energy electron gain signal is distinguished in the rotation of cylinder bar 40 and gliding motility, to calculate direction and the displacement at the cursor movement of X and Y-axis.
