Description of the invention (4) Connected to two optical sensors 42, 44, squeezed out ★ Even if you want to put out vomiting according to the two optical The displacement signals generated by the sensors 42 and 44 change the Jianli PD ni π-^ change the position coordinates in the memory S memory 50 so that it can display the joystick in real time 1 夕 θ 姐, sister-* ^ ,, θ ′, the position of the head of 4 and a general signal based on the position display, and output to a computer through the private port, .u —, output port 52 (not shown,,,, 15 for Correct the position coordinates of the control lever 14. When the spherical grip 22 is a kind of possible opening 16 and the bottom end of the hemisphere is shaken perpendicular to two, the transmission mechanism 24 and the sensor 42, 44 will divide the displacement signal, The processor 54 and the rotation angle, that is, the position coordinates (X, Υ) of the position △. At the same time, the processor 54 vector signal and the middle part of the output control lever 14 includes a transmission provided in the shape of the upper end of the housing 12 by means of rocking back and forth and left and right. The mechanism 24 is arranged on the pivot shafts 38 and 40 of the control lever 14. The control lever 14 is driven simultaneously The two rotating shafts 38 and 40, at which time the two light beams will generate corresponding displacement signals. Through these, the rotation directions X and ΔΥ of the two rotating shafts 38 and 40 will be calculated in real time and accumulated into the memory 50 to make it real-time. At present, the display control lever 14 will continue to generate a port 52 output according to the position coordinates. ^ Η In order to correctly generate the flood number, the processor 5 4 must continuously accumulate the phase = shift signal to the storage. If Yu Jiguo has mistakes in this accumulation process, it may cause accumulation errors. The position coordinates within 50 must be calibrated. This indicates the current position of the joystick 14 and the memory generated by the two optical sensors 42, 44. Position coordinates within the body 50. If a signal or condition occurs, these errors are stored in memory in this case, otherwise the processor 5 may produce

Fifth, invention reward " '^ Wrong vector signal. In addition, when starting to use the computer to shake 10, the electric = joystick 10 also needs to be able to set the starting coordinates of the joystick 14 so that the processor 5 may begin to accurately accumulate the current position of the joystick 丨 4. There are many ways to correct the position coordinates (X, Y) of the joystick 14. The correction button 15 is used to correct the position coordinates of the joystick 丨 4. The use of the correction button 5 is very simple. Pressing the correction button 15 causes the processor 54 to reset the position coordinates (XY) to zero. Therefore, when the control lever 14 is in a state without external user intervention, the user can use the correction button 15 to reset the position coordinates (X, Y) to zero. The correction button i 5 can also be used in conjunction with other predetermined positions. For example, the manufacturer of the computer joystick 10 can store the position coordinates of a predetermined position in the memory 50 and ask the user to adjust the position coordinates (X, Y ), It is necessary to move the control lever 14 to the predetermined position, and then press the correction button 15 so that the processor 54 can set the position coordinates (X, γ) to the position coordinates of the predetermined position. The signal generated by pressing the correction button 15 can also be sent by a computer, that is, the user can send a correction signal from a computer connected to the output port 52 of the computer joystick 10 to cause the processor 54 to position Coordinates (X, Y) are properly corrected. If the correction button 15 of the computer joystick 10 is used in this way, it is unnecessary to save costs. The above method requires the user to place the joystick 14 in a predetermined position, and then use the computer joystick 10's correction button 5 or a connected computer to correct the position coordinates (X, γ) of the joystick 14, so not convenient. Fig. 4 shows a design for automatically correcting the position coordinates (X, γ) of the control lever 14.

V. Description of the invention (6) Two: * Fig. 4 is another computer rocker 60 ′ of the present invention. It differs from the computer rocker 10: the computer rocker 60 uses a position detector 62, And ^ correction button 15, the position of the joystick 14 is measured and the position coordinates (X, γ) of the joystick 14 are automatically corrected. The circuit structure of the computer joystick 60 is similar to that of the 2-brain joystick, except that the correction button 15 is replaced by the position detector 62. ≫ The position detector 62 is located below the joystick 14 and includes a reflective sheet 64 provided at the bottom end of the transmission mechanism 24 in the shape of a hemisphere for reflecting light. A light emitting diode 66 is provided in the reflective light. One side below the sheet 64 and a light f sensor 68 are disposed on the other side below the reflective sheet 64. The light emitting diode 66 and the light sensor 68 are both electrically connected to the processor 54. When the control rod 14 passes or is located in a predetermined upright position, the light emitted from the light emitting diode 66 will be reflected by the reflective sheet 64 to the light sensor 68. At this time, the processor 54 will immediately know through the output of the light sensor 68 and automatically reset the position coordinates (X, γ) of the joystick 丨 4 to zero. When the joystick 14 is used, the processor 54 will continue to rotate the rotation directions and rotation angles of the two rotating shafts 38 and 40, that is, △ and 8 Y are accumulated, and β is ten to s. ) So that it can display the current position of the joystick 14 in real time. When the joystick 14 passes & is located at the predetermined upright position, the processor 54 will immediately reset the position coordinates (X, Y) to the zero house and automatically correct the position coordinates (χ, Y). This reduces the number of ways I can accumulate "the errors generated during the process can be automatically corrected ... and the mask does not require the user to correct in other ways.
