Description of the invention (1) 5-1 Field of the invention: The present invention relates to an electromagnetic induction system of an induction circuit, in particular to a specific single induction circuit and multiple induction circuits Electromagnetic induction system. 5-2 Background of the Invention: Since handwriting input circuit devices can replace mice, and are more suitable for users to enter text and patterns by manual input, the improvement of handwriting input circuit devices has been urgent in recent years. Areas of development. Earlier handwriting input circuit devices replaced pens with pens, and in order to improve user convenience, wireless pointing devices (pens, mice, pointing pads, etc.) and tablet tablets (tab let ) Both replace the mouse, where the tip of the wireless pen usually corresponds to the left button of the mouse. Although traditional pen-type input products have been available for many years, similar products are focused on single-function applications such as drawing or Chinese input. Traditional electromagnetic induction systems are equipped with a tablet and a mouse or pen-type transducer / pointing device. In general, there are two modes for determining the position of a trace point on the surface of a tablet: one is a relative mode, and the other is an absolute mode. Generally, the mouse device operates in a relative mode. When the mouse rolls on the surface of the tablet, the computer system will receive input from the mouse. It can only recognize the relative movement of the mouse in the X and Y directions. The technology uses a sensing device in the mouse to form a pair of transformations that are perpendicular to each other.

Description of the invention (2) Signal 5 Tiger 'This signal is opposite to the vertical response of the mouse & the cursor device in the tablet, corresponding to the movement, for example, generally operates in absolute mode. . If you lift the cursor device "::: on the other-position on the surface of the standing tablet, the computer system will reflect a new absolute position of the cursor device. It is known that, and 0 now, there are many The method is used to determine the position of the cursor device on the surface of the tablet that supports r ^ P /, and among them, the electromagnetic field induction technology is a technology commonly used in absolute mode. Early transducer / index device systems The multi-conductor is electrically connected to the tablet, and then the position and button / pressure information is transmitted to the computer system through the computer transmission interface. In some traditional technologies, wireless transducers / pointing devices are used by default. The frequency and / or phase changes are used to represent the non-azimuth state of the function of the transducer / indicator device. These functions include: pressing the button, the pressure of the indicator device, or similar functions. B. Processing, the frequency change is prone to a variety of external factors, such as metal items, noise, external incoming magnetic fields, etc., which leads to the misjudgment of the function of the indicator device. Especially in larger digital tablets These problems become more obvious. The improved technology of the traditional tablet system allows users to use the pointing device in a dual mode operation, so it can provide relative movement or absolute position information under the user's control. Current indicators Device-type input products are usually an electromagnetic induction circuit device. Electromagnetic induction devices usually include an electromagnetic pointer device and a digitizer tablet (hereinafter referred to as a tablet). The electromagnetic pointer device has a battery to supply emission-related information. The energy of electromagnetic signals, and

Taking the electromagnetic indicator device as an example, when the pen tip of the indicator device is touched, a change in the inductance value will be generated ', so that the oscillation frequency also changes accordingly. The greater the pressure on the tip of the pressure indicator device, the greater the change in inductance, and therefore the greater the change in the oscillation frequency. Therefore, the magnitude of the pressure applied to the tip of the indicator device can be known from the change in frequency. There are also two switch buttons on the side of the wireless indicator device. The engagement / disengagement of the buttons causes the specific capacitor in the oscillator to add / not add oscillation, so the transmission frequency of the indicator device is changed. It can be determined by the difference in frequency Why is the switch button pressed by the user pressed? In addition, the digital tablet (t ab 1 e t) also includes components such as a detective loop, an amplifier, and an analog to digital converter (ADC). The central writing area of this type of traditional handwriting tablet is woven by induction circuits. In this area, the circuit is arranged on both sides of the circuit board and the two induction circuits are equidistantly arranged in an array. The main purpose of this induction circuit is only to receive electromagnetic signals emitted by dedicated electromagnetic indicator equipment. When an electromagnetic indicator device transmits an electromagnetic signal, the induction circuit will receive the electromagnetic signal and process it through the circuit to obtain information about the indicator device. Generally speaking, the induction circuit and layout design of the traditional electromagnetic induction device use the induction circuit. X and Y axis arrays are arranged equidistantly to form a grid, and its absolute coordinates are obtained by inductive electromagnetic index equipment and calculations. Referring to the layout of the induction circuit arranged along the X direction of two-dimension orthogonal coordinates shown in the first A diagram, one switch (X1 to X2 5) is connected to one end of each induction circuit 11 0 A.
