Description

13〇5320 九, invention description: [Technical field to which the invention belongs] should be installed = meaning

[Prior Art J, in the sensing device of each face type, and has been turned over in computer systems and other applications, this kind of device is the "thief," the name is the computer. The part, and requires a plane, the dirty ball can roll on it, and 曰, in order to have a reasonable degree of translation, the mouse usually needs to scroll longer, and finally the mouse needs to move the cursor, thus disturbing The main purpose of people typing from the computer. ° After many attempts, people tried to provide a kind of device to check the position of the finger to check the position of the finger. This kind of equipment domain chicken is low Wei, high solution is now available Type-reading sensing devices, such as resistive, inductive, and capacitive: - - Patent No. 653497, published by the US Patent and Trademark Office on March 18, 2003 = a type of read position detection using inductive technology Technique, the technique comprises two parts, the first ten-eighth generates a changing magnetic field by spatially rotating around the rotating axis, and the second part comprises two sensing electrodes to sense the magnetic field generated by the first part and correspondingly Signal, the above signal changes with the relative angle of the first & and the two parts, then the relative position of the first part of the disc can be measured according to the change signal. Knife, as the US Patent and Trademark Office 2003 Patent No. 6545614, which is hereby incorporated by reference, which discloses a resistance sensing device comprising a oscillating circuit unit and an electronic node unit, the oscillating circuit unit providing a high frequency signal for the electronic node unit, If the debt detector detects an object such as a finger touch, the 'electronic node unit's resistance changes accordingly'. When the finger touches the electronic node, the generated electric power matches the resistance of the electronic power-saving input terminal, and the reflected wave becomes small. By detecting the reflected wave and comparing it with the bismuth unit, if the reflectance becomes smaller, the object touch can be determined. ....., as disclosed in the US Patent and Trademark Office on February 27, 1996, the patent number is 5495. The '77 patent discloses a capacitive position sensor having a characteristic capacitance on a wire in a vertical and horizontal direction connected to the sensing pad. The movement of the body touches or the movement of the corresponding matrix of the object changes, and the change of the capacitance of each intersection of the X and γ directions in the matrix is changed.
