New Description: [New Technology Field] This creation is about a technique of coordinate input, especially an inductive coordinate input device. [Prior Art] Press, generally input electronic devices such as computers, mobile phones, etc., the signal input method uses the external keyboard to input signals, and the signals are transmitted to the circuit components inside the electronic device to achieve the utility of the operating electronic components. However, due to the input of the keyboard, the keyboard space is required, so that the electronic product can not be made thin and short. One of the current technologies can replace the above-mentioned resistive touch panel with keyboard input. The user only needs to apply pressure on the touch panel by means of a hand, an inductive pen or other indicators, by using upper and lower indium tin oxide. (Indium Tin Oxide, ITO) contacts the 'inductive signal output' to the electronic device to interpret the position of the touch panel. However, the disadvantage of this technology is that if the insulation resistance is not large enough, it will cause interference, that is, a short circuit condition. Will cause the computer to produce the wrong action. Therefore, the present invention proposes an inductive coordinate input device to effectively overcome the above-mentioned problems, and the specific architecture and its implementation will be described in detail below. [New content] The main purpose of this work is to provide an inductive coordinate input device that uses image sensing to determine the coordinates of the object moving on the coordinate_area and output it to the control module or host. . The other purpose of this creation is to provide an image of the object directly viewed by the side county image device, and the side inspection surface is the coordinate position of the object on the coordinate frame. A further refinement of the present invention is to provide an inductive coordinate input device that can be built into a display or external to the display. 5 M359744 In order to achieve the above purpose, the present invention provides an inductive coordinate input device, which comprises a target detection area, an object moves in the coordinate detection area; and two image capture devices are respectively located in the coordinate extraction area. a four-corner for capturing an image position of the object; and at least one control module for receiving the image position captured by the image capturing device, calculating at least two angles of the image capturing device and the object, and calculating the object at the coordinate detection One of the coordinates of the zone. By the detailed description of the specific embodiments, it is easier to understand the purpose, technical content, characteristics and the effects achieved by the present invention. Φ [Embodiment] The present invention provides an inductive coordinate input device. As shown in the first figure, the inductive coordinate input device 10 of the present invention comprises a standard measuring area 12, two image capturing devices 14 and at least one control module. In the group 16, the two image capturing devices 14 can be respectively disposed at the lower left and lower right corners, the upper left corner and the lower left corner of the coordinate detecting area 12, or the upper right corner and the lower right corner. The coordinate detecting area 12 is composed of an object 18 The object 18 can be a user's finger or an indicator. The imaging device 14 is provided with an inductive component 142 and a lens 144. The sensing component 142 passes through the lens 144 to capture the image position of the object 18. Therefore, the two sensing elements 142 can obtain two image positions; after receiving the image position captured by the image capturing device η, the control module 16 calculates the two angles between the image capturing device 14 and the object 18, thereby calculating that the object 18 is located. The coordinate value of one of the coordinate detection areas 12. The inductive coordinate input device of the present invention can be used independently of a display, externally attached to the display, or the inductive coordinate input device can be directly used in the display. The creation can also set a set of auxiliary light sources, which can be located at the back of the coordinate detection area or the internal auxiliary light source of the image capturing device is invisible light. Since the present invention does not need to provide a reflection light such as a mirror or a reflection frame 6 M359744 around the inductive coordinate input device 1 , in addition to greatly reducing the overall area of the inductive coordinate input device, making it lighter, thinner and shorter, And can increase the manufacturing flexibility, for example, the original inductive coordinate input device used in the 12" when it is applied to the 13 pairs of panels, only need to be modified in the soft body, no need to re-open the mold to create a new frame 'more free Adjusting the installation position of the image taking device; in addition, the frame without reflecting light can reduce the material cost and development cost, and accelerate the development time of different modules. In summary, the inductive coordinate input device provided by the present invention uses the two image capturing device to capture the image of the object. The image capturing device can be installed at any two corners of the four corners of the coordinate detecting area to capture the image of the object.
