Description of the Invention (Technical Field „Equipment--. II (Please read the precautions on the back before filling out this page) According to the above content, the present invention will be used to point to the element, when the screen on the screen is moved. The cursor can be moved up and down or left and right correctly, and the pointing file can be used in a small computer system such as a notebook computer. ^ 2 Conventional Technology The present invention relates to a personal belt type notebook computer marking device. In order to be able to be installed on a computer such as a personal notebook computer, the structure is changed to a simplified pointing device and a method of curbing the position of the cursor. In a computer with a display system, the cursor on the curtain is moved freely Many kinds of devices have been prepared, among which the device with the most users can be said to be a mouse. The mouse uses a ball that can be swiveled, or a device that searches for infrared rays and receives infrared rays to transfer the mouse's motion to the computer System and let the cursor on the screen move. The Central Standards Bureau of the Ministry of Economic Affairs, Shellfish Consumer Cooperative, printed ball mouse can be made at a low price, The ball and other mechanical parts constituting the ball mouse are affected by factors such as dust and dirt, which not only causes problems in the precision of the mouse, but also changes in the sliding of the ball according to the state of the bottom surface. No mechanical action is required, and the pattern of the pad is optically checked. So the action is very subtle without sliding, but the price of the two-dimensional optical sensor of the mouse material is quite high, and the price of the mouse is also from the Ministry of Economic Affairs Printed by the Central Bureau of Standards Consumer Cooperatives 40623t at _B7_ V. The description of invention will rise, so this factor will limit the number of users. In order to solve the above problem, the application of the patent 98-24505 proposed the use of a toggle lever and Cylindrical rod to stop the pointing element of the cursor position on the screen. The above-mentioned pointing element is mainly a toggle lever (30) with a certain spacing line to the left and right as shown in the first figure. The first cylindrical rod (40) that performs the revolving motion similarly uses the center axis of the first cylindrical rod (40) as the axis and has a plurality of lines with a certain interval. A second cylindrical rod (46), support rods (42) formed on both sides of the first cylindrical rod (40), and a telescopic connecting rod (50) connecting the first cylindrical rod (40) and the second cylindrical rod (46). The second picture shows the method and pattern of using the pointing element to stop the cursor position. Please refer to the first or second picture to explain the operation of the existing pointing element, as described below. From the first and the second The infrared rays generated by the infrared light emitting diodes (14, 16) are investigated by the horizontal sensing portion (34) and the vertical sensing portion (48), and the investigated infrared rays are reflected by the horizontal sensing portion (34) and the vertical sensing portion (48). Then, after being received (S14) by the first optical fiber (22) and the second optical fiber (24), this infrared light is input to the first and second photoelectric crystals (18, 20). The first and second photoelectric crystals (18, 20) are converted into signals having a certain phase and amplitude and output (S16). The first optical fiber (22) is composed of a pair of optical fibers (22a, 22b), and the second optical fiber is also composed of a pair of optical fibers (24a, 24b). Because the infrared rays pass through the 4 paper standards, the Chinese National Standard (CNS) A4 specification (210 ^ 297mm) is applicable. I. " ------ >> -------- II-^ ---- ^. -: Two-,-{Please read the notes on the back before filling this page) Printed by the Consumer Cooperatives of the Central Standards Bureau of the Ministry of Economic Affairs __406236 b7_ V. Description of the invention () Each optical fiber is covered by the first and second photoelectric crystals (60 (61) The receiving time is different, so different optoelectronic crystals will have different phases. The microcomputer (12) compares the phase difference (S18) of the signals Ea and Eb occurring in the first and second photoelectric crystal meetings (60, 61). If the phase difference is positive, set the cursor's moving direction to the positive direction (on the screen, the X-axis or Y-axis is positive) (S20); if the phase difference is negative, set the cursor's moving direction Set to the negative direction (the negative direction of the X axis or the negative direction of the Y axis on the screen). Calculate the number of phases that occur to get the moving distance of the cursor on the screen. However, the above-mentioned pointing elements should be provided with support rods (42) on both sides of the first cylindrical rod (40), so the production process and expenses will be increased. In addition, in order to transmit the rotation movement of the first cylindrical rod (40) to the second cylindrical rod (46), a support rod (42) and a telescopic connecting rod (50) are provided. However, after repeated use, dirt and other dirt may accumulate in the connecting portion of the support rod (42) and the telescopic connecting rod (50). Then the movement of the connecting part of the support rod (42) and the telescopic connecting rod (50) will be inaccurate, and the X-axis movement of the cursor on the screen will also be affected. According to the method for stopping the position of the cursor, if the movement of the toggle lever (30) stops suddenly, it will be the same as the signal output by the first and second photoelectric crystals (18, 20), so the movement of the cursor cannot be stopped.

The computer system moves the position of the cursor (S20, 22) on the screen according to the received information. When the position of the cursor is continuously moved, if the phases of the output signals from the first and second photoelectric crystals (18, 20) are the same, the microcomputer (12) performs the following steps to determine the magnitude of the signal. Figures 7A, 7B, and 7C show the amount of infrared reflection at this position when the a, b, and c of the horizontal sensing part (24) of the optical fiber (22a, 22b) is set by the lever (30). Chart. The seventh diagram A shows the amount of infrared reflection of the optical fiber (22a, 22b) when it is a (that is, a non-reflective area) of the horizontal sensing portion (72). Line 7B shows the amount of infrared reflection when the optical fibers (22a, 22b) are at b (that is, the reflection area) of the horizontal sensing portion (34). Figure 7C printed by the Consumer Cooperatives of the Central Bureau of Standards of the Ministry of Economic Affairs shows that the optical fiber (22a, 22b) in the horizontal sensing section (72) c (that is, formed at both ends of the horizontal sensing section (72) has more than twice the amplitude Reflection area). B and c of the horizontal sensing part (72), although they are in the same reflection area, show different reflection amounts because b is a close distance between the reflection area and the non-reflection area, so it is interfered by the non-reflection area Will reduce the amount of infrared reflection. π This paper is from China National Automobile (CNS) Α4 threat (210x297 male thin) 40623 ^ A7 B7 V. Description of the invention () ~ 疋 c is a wide reflection field, so it will not be affected by Non-reflective domain interference. According to the above pattern ', it can be known that when the optical fiber (22a, 22b) senses c of ° P (72) horizontally, the amplitude of the signal generated from the first and second photoelectric crystals (a, 20) is the largest. ° When the size of the signal generated by the microcomputer (12) from the optoelectronic crystal is the largest (s34), it is judged that the lever (7G) is moved to the right or left and transmitted to the computer system. Β The computer system receives the Information, move the cursor position on the screen to the end of the screen (S36, S38). Under such circumstances, if the white ray reflective field and the black line's non-reflective field interchange roles, simply, that is, the infrared cursor reflected by the reflective field does not sense the movement of the cursor, but the non-reflective field If the infrared non-reflection degree senses the movement of the cursor, a non-reflection area is generated at both ends of the horizontal sensing portion (72) to minimize the amount of infrared reflection. At this time, we can judge that the toggle lever is moved to the extreme end. Printed by the Consumer Cooperatives of the Central Bureau of Standards of the Ministry of Economic Affairs
