The signal is controlled by the circuit, and the circuit control determines the position that falls on the _, and the displayed score is displayed by the danger device according to the position, or a different sound is emitted to enhance the effect. In addition, the interface is provided to provide the desired settings to select the desired effect. j Guanxiong The skills of the conventional technology can be divided into two categories, the first type is realized by mechanical switching technology, and the second type is electromagnetic technology. The first type of mechanical technology can be referred to U.S. Patent No. 4,572,521 and Taiwan Patent No. 84. The internal structure is mainly a circular radial orifice plate, with the inner cup-shaped her structure, the sliding skeleton stove structure, the elastic buffer layer and the __ layer to form the structural frame of the silk area. The function is to touch the switch of the conductive film layer through the reciprocally displaceable cup-shaped structure, and turn it on, and the microprocessor of the circuit board (10) can be the area where the medium is shot. 201010764 ^ The main disadvantage of class I mechanical technology is that production and assembly are not easy. Because the design requires the design of a complex (10) cup-shaped touch structure and an elegant rebound structure, the cup-like structure inside the field will cause the cup-shaped structure to follow along the inevitable tolerances during the formation process. The frictional force when the track slides is too large, and the surplus method will fly the kinetic energy of the brocade, and the film will not be able to conduct, and the position of the dart cannot be detected, that is, there is no reaction.

Referring to Fig. 4, there is shown a schematic diagram of the electromagnetic flying fly of the present invention, wherein the electromagnetic fly type 3 cooker-soft central type broach pin 32 money-relying body 34, the lining body % comprises - mutual inductance coil 35 and - flyway plate 37. The milk can receive electromagnetic waves, and the dart board 37 includes a capacitor and other electronic components (not shown) such that the mutual inductance coil 35 and the capacitor are combined into a resonant circuit for storing the power induced by the electromagnetic waves. Further, the mutual inductance coil 35 emits electromagnetic waves using the stored electric power when there is no incident electromagnetic wave. The electromagnetic lining 3() further includes - the magnetically permeable material 36' is surrounded by the mutual inductance coil 35 forever increasing the magnetic flux, increasing the ability to receive electromagnetic waves and the intensity of the emitted electromagnetic waves. The electromagnetic dart 3G can also have a shaft 38 and a darts tail 39 for balancing the center of gravity and maintaining a stable tree diameter. Since the dart 30 can use the internal resonance circuit to obtain power, it is a passive dart without the need to provide a power supply such as a battery, so that the electromagnetic lining 3 () reports a light throw projection, and because of the simple 32 soft pointed shape Appearance, safety after use. Referring to Figure 5, a schematic view of the electromagnetic dart body of the present invention. The electromagnetic zijin 201010764 of the present invention has a wire frame 42, a display device 43, an orifice plate 44, a plurality of 线圈-shaped coils, a circular coil 48, and a chassis 49, wherein the dart training frame 42 and the bucket peripheral are recorded. The surface of the dry frame 42 has a plurality of sectors or surfaces, and the display member 43 is located on the dart frame 42 to provide the face to display the desired information, such as scoring, shooting, or not shooting. It is located under the miscellaneous frame 42 and has a plurality of holes for absorbing the impact energy of the electromagnetic flying screw 3G to protect the internal surface. ❹ Ο The output 46 is located on a first insulated circuit board (not shown) on the 'divided and split complex nano-Num display', = the sector coil 46 can represent the angular coordinate, and the same two t-turns of the plurality of sector coils 46 and the plural The concentric circular coils 48 are superposed to divide the entire plane into a plurality of parts to look around the block circle, that is, two or two = = block can be - pick up fine _ 46 lang knife ^ circuit 52 has a transmission mode and a receiving mode. In the path 52, the sector coil controls the transmission section 46 to switch to the 2 magnetic waves and uses the resonance circuit residual_wave_in the receiving mode, since the sector coil 46 does not mention the field power supply. The power supply, the _ fly record 201010764 to the 4 gate control off 54 will _ 46 cut_receive circuit 58, such as the amplifier-based circuit shown in the figure, using the sector coil 46 to receive the electromagnetic wave of the electromagnetic fly recording 30 ' The signal is amplified by the receiving circuit 58, that is, the induced potential generated by the sector coil 46 is obtained. The transmit circuit % and receive circuit 58 of Figure 6 are merely exemplary examples to illustrate the features of the present embodiment, and are not intended to limit the scope of the present invention, and other conventional techniques may be used. The electromagnetic cymbal 40 can further include a transmitting antenna (not shown) for emitting electromagnetic waves 'instead of the fan coil and the concentric circle _ as the transmitting electromagnetic wave, and the 闸 ϋ 4 4 4 4 会 会 会 会 会Will emit the output of the circuit. The launch 夭愧. (1) In addition, the W circle 48 is also controlled by a concentric circle circuit (not shown) of the function class 2 of the sector coil control circuit 52, and also has a receiving and transmitting mode trV. 1 Note that in the transmitting mode It can be similar to the selection of the fan coil 46 22 2 48 * electromagnetic wave emission source, that is, the fan coil 46 and the concentric coil 48 can be used as the electromagnetic wave source without time.电磁 Electromagnetic miscellaneous (4) of the present invention includes a main control (not shown) for controlling the operation of the magnetic circuit, including two pairs of slightly controlled, 54, and the same: the same control circuit 52 and the concentric coil control circuit 2 Out-to-light processing to obtain electromagnetic _ 3W at the electromagnetic miscellaneous 4G position, and then determine the score value and other operations. askH month I skin? The electromagnetic hybrid 40 of the electromagnetic machine also adopts digital modulation, as shown in FIG. C_ct ' is the center frequency - the high frequency ==' using the electric crystal Zhao or other closed control circuit as the switch can be used to make the output signal to the sine wave output or cut off without waveform input 201010764. The modulated signal M(t)C〇S&M emits electromagnetic waves via a coil or other transmitting antenna. The ASK modulation method is: when the signal is at logic 1, that is, in the transmission mode, the line composed of the capacitor and the mutual resonance resonance in the electromagnetic dart can generate resonance due to the gradual increase of the magnetic flux. The induced current is also gradually increased, and the resonant coil in the fly recording is connected to the rectifier circuit to serve as a power source for the internal circuit. When the signal is in the logical state, that is, in the receiving mode, the electromagnetic dart starts to use the energy stored in the previous logic 1 and then emits electromagnetic waves to the dart, so, when the dart is close to the surface of the dart, the dart machine The internal main controller can detect the power: the magnetic dart is close to and where it is shot. Even if the electromagnetic dart is not firmly projected into the surface of the electromagnetic target, it can be bounced off, or only the side of the electromagnetic dart hits the surface of the electromagnetic target. Referring to Figure 8, the coil receiving signal distribution map of the electromagnetic dart target of the present invention. The main controller controls and stores the electric signal output from the fan coil control circuit and the concentric coil control circuit, which can be used to make a circle and __ potential potential distribution map, as shown in Fig. 8. The position with the highest induced potential in the figure is the position where the electromagnetic dart falls on the electromagnetic dart. The main controller may have a processor and a memory, and the software program required to store the memory' is executed by the processing! I to implement the features of the present invention. In addition, the memory can use an external memory instead of built-in memory: at the same time, the memory can be a read-only memory (ROM) or a flash memory, or a hard disk drive or other non- Volatile memory. Therefore, the present invention utilizes the ASK modulation technology and the position of the fan coil and the concentric circle coil 丄 伽 (4) electromagnetic scale, and cooperates with the safe soft flying scale needle to provide a dart target machine with safety, high precision and reliability. 11 201010764 = The above is only a difficult example of the transfer of the book (4), and it is still necessary to make any form of the invention according to the invention, so that any modification in the _ = invention should still be included in this Hair = [Simple description of the diagram] Figure 1 is a schematic diagram of the conventional technique.
