[0024] Example

[0025] A POS machine that can effectively prevent peeping, such as Figures 1-4As shown, the POS machine includes a POS machine body 1, which is equipped with an anti-peeping component 2 for manual anti-peeping. The internal electronic components and circuits of the POS machine body 1 are all existing technologies and will not be described in detail here. The front of the POS machine body 1 is equipped with a thermal paper tray and a thermal paper slot. The front of the front of the POS machine body 1 is equipped with a display screen 3, and the front of the rear is equipped with a keyboard 4. The brightness of the keyboard 4 is adjustable. The rear of the POS machine body 1 is equipped with a chip card reader 6, and one side of the outer wall of the POS machine body 1 is equipped with a magnetic stripe card reader 5. The anti-peeping component 2 includes a mounting plate 14, which is symmetrically arranged. The mounting plate 14 is inclined upward at 10-15 degrees from the front to the rear of the POS machine body 1. The top of the mounting plate 14 is equipped with a sliding groove 15, in which the anti-peeping plate is slidably installed. 17. A toggle plate 19 is provided on one side of the top of the privacy panel 17. A limit mechanism is provided on the mounting plate 14. The POS machine also includes a control module. The limit mechanism includes an electromagnetic magnetic attraction device body 16. The electromagnetic magnetic attraction device body 16 is installed on the top of the front and rear ends of the mounting plate 14 and is located at the end of the slide groove 15. The electromagnetic magnetic attraction device body 16 is an existing technical solution and will not be described in detail here. A transparent glass is provided in the middle of the privacy panel 17. A privacy film 20 is provided on the transparent glass. The privacy film 20 can achieve the privacy design using existing technical solutions. The working principle and specific model will not be described in detail here. The slide groove 15 has a "convex" shaped cross section. A slide seat 21 is provided at the four corners of the privacy panel 17. A ball bearing is provided at the bottom of the slide seat 21. An iron plate is provided on the outer surface of the slide seat 21. The control module controls whether the main body 16 of the electromagnetic magnetic attraction device generates a magnetic field. When the main body 16 of the electromagnetic magnetic attraction device generates a magnetic field, the magnetic force fixes the main body 16 of the electromagnetic magnetic attraction device to the slide 21. When the main body 16 of the electromagnetic magnetic attraction device does not generate a magnetic field, the slide 21 can be released and the privacy screen 17 can be slid to prevent the privacy screen 17 from sliding when the password is entered, thereby avoiding the risk of exposing the password.

[0026] This device is further configured such as Figure 2 As shown, the POS machine body 1 has two pairs of threaded holes 13 on its left and right sides, and the mounting plate 14 is installed on the left and right sides of the POS machine body 1 by screws. By using screws to install the mounting plate 14 on the left and right sides of the POS machine body 1, it is convenient to choose whether to install the anti-spy component 2 according to actual needs.

[0027] This device is further configured such as Figure 3As shown, a connecting plate 10 is bolted to the back of the POS machine body 1. An elastic band 11 is provided on the connecting plate 10, and a pressure sensor 12 is installed in the middle area of ​​the connecting plate 10. The pressure sensor 12 is electrically connected to the control module. When holding the POS machine body 1, the palm passes through the elastic band 11, pressing the pressure sensor 12. The pressure sensor 12 sends an electrical signal, and the control module sends a signal to the electromagnetic magnetic attraction device body 16, energizing the electromagnetic magnetic attraction device body 16 and creating a magnetic attraction between the electromagnetic magnetic attraction device body 16 and the slide 21. When the pressure sensor 12 is released, the electromagnetic magnetic attraction device body 16 is de-energized, releasing the slide 21 and facilitating the movement of the privacy screen 17. This method prevents the privacy screen 17 from sliding due to external factors when the user is entering a password. If someone deliberately approaches the user and slides the privacy screen 17, this can be prevented. Simultaneously, the use of the elastic band 11 improves the user's grip on the POS machine, preventing someone from deliberately snatching it.

[0028] This device is further configured such as Figure 2 , Figure 4 As shown, an ambient light sensor 7 is installed on the front of the POS machine body 1 near the front end. The ambient light sensor 7 is electrically connected to the control module. A light shield 18 is installed on the privacy panel 17 near the front end of the POS machine body 1. The light shield 18 and the privacy panel 17 are integrally formed. When the privacy panel 17 slides backward, the light shield 18 on it moves away and no longer blocks the ambient light sensor 7. The sensor 7 detects an increase in ambient light intensity and sends a signal to the control module. The control module increases the backlight brightness of the keys on the keyboard 4 to compensate for the decrease in light transmittance caused by the privacy film 20. When the privacy panel 17 slides forward to reset, the light shield 18 covers the ambient light sensor 7 again. The sensor 7 detects a decrease in ambient light intensity, and the control module reduces the backlight brightness of the keys on the keyboard 4 to the default value.

[0029] This device is further configured such as Figure 3 As shown, a strip-shaped pad 9 is provided at the front bottom of the POS machine body 1, and cylindrical pads 8 are symmetrically provided at the rear bottom of the POS machine body 1. The cylindrical pads 8 and the strip-shaped pads 9 are provided to prevent the POS machine from being bumped or knocked when placed.

[0030] The circuit connection between the control module and the individual components adopts existing technical solutions. The parts not involved in this device are the same as or can be implemented using existing technologies.

[0031] Working Principle: This design is primarily for handheld password input scenarios. When a password is required, the user picks up the POS machine, passing their hand through the elastic band 11 and pressing the pressure sensor 12 with their palm. Simultaneously, the electromagnetic magnetic attraction device 16 at the front of the POS machine body 1 is de-energized, releasing the slide 21. The electromagnetic magnetic attraction device 16 at the rear of the POS machine body 1 is energized, generating magnetic force. Then, the user manually moves the dial 19, causing the privacy screen 17 to block the keyboard 4. When the privacy screen 17 moves to the rear of the POS machine body 1, the electromagnetic magnetic attraction device 16 magnetically attracts the slide 21. At the same time, the ambient light sensor 7 detects changes in light intensity, and the control module increases the brightness of the keyboard 4 keys. After entering the password, the user puts down the POS machine, and the electromagnetic magnetic attraction device 16 at the rear of the POS machine body 1 is de-energized, releasing the slide 21. At the same time, the electromagnetic magnetic attraction device 16 at the front of the POS machine body 1 is powered on, causing the electromagnetic magnetic attraction device 16 to generate magnetic force, which then pushes the privacy panel 17 to the front of the POS machine body 1. The electromagnetic magnetic attraction device 16 at the front attracts the slide 21. Then, the ambient light detection sensor 7 detects the change in brightness, and the control module adjusts the brightness of the keyboard 4.

[0032] The above are merely preferred embodiments of this utility model. For parts that do not require creative effort in circuit control, signal control and transmission, please refer to the prior art. However, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and utility model concept of this utility model, should be included within the protection scope of this utility model.
