Embodiment Construction
[0020] like figure 1 As shown, the infrared detection device in the present invention combines the method of digital signal processing technology to identify two types of film, the copy film and the traction film. The infrared detection device is composed of two fixed plates 1, four supports 2, an infrared transmitting circuit 3 and an infrared receiving circuit 4. The three lines are respectively a power supply line (5V), a ground wire, and a signal line. In the infrared detection device of the present invention, it is Integrating the infrared transmitting circuit with the analog filter circuit. The four brackets 2 are used to support the front and rear two fixed plates 1 and are located between the front and rear two fixed plates 1 . The infrared transmitting circuit 3 and the infrared receiving circuit 4 are used to detect the film 5, including the copy film and the leading film, which are respectively located on the front and rear two fixed plates 1; considering that the ...
