[accompanying drawing explanation]
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation.
Fig. 1 is the structural representation of embodiment of the present invention ATM encryption password keyboard.
Fig. 2 is the partial enlarged drawing at I position in Fig. 1.
[detailed description of the invention]
The structure of embodiment of the present invention ATM encryption password keyboard is as it is shown in figure 1, include microcontroller 1 and data storage 2, power supply, circuit board, shade 3, flexible PCB 6 and flexible PCB 7.
Circuit board includes mainboard 4 and subplate 5, and the circuit of mainboard 4 and the circuit of subplate 5 electrically connect, and microcontroller 1 and data storage 2 are all arranged on subplate 5；Being also equipped with two light-detecting devices 501 on subplate 5, the signal output part of light-detecting device 501 connects the control signal input of microcontroller 1；Shade 3 is buckled on mainboard 4, and subplate 5 is fixed on mainboard 4, is arranged in the cavity of shade 3.
Shade 3 is metallic shield, and the upper surface of mainboard 4 has a circle ring-shaped groove 401, and the edge 301 of shade 3 opening is inserted in ring-shaped groove 401, and under normal condition, shade 3 is internal is dark surrounds, it does not have light can enter in the cavity of shade 3.
The periphery of flexible PCB 6 is fixed on mainboard 4, covers shade 3；The input termination power of flexible PCB 6, output termination mainboard 4 circuit, electrically connected with the control signal input of microcontroller 1 by mainboard 4 circuit and subplate 5 circuit.
Flexible PCB 7 is installed in shade 3, covers subplate 5；The periphery of flexible PCB 7 is fixed on mainboard 4, and the input of flexible PCB 7 connects power supply by connecing mainboard 4 circuit, and outfan electrically connects with subplate 5 circuit, is connect the control signal input of microcontroller 1 by subplate 5 circuit.
