Embodiment
1-3 is described in detail to specific embodiment of the present utility model, it is necessary to explanation is below in conjunction with the accompanying drawings, Fig. 1
In do not draw printer, printer is peripheral apparatus, is directly connected with data wire during use.
The utility model includes Raspberry Pi master control borad, printer (preferably laser printer), power module, two high definitions and taken the photograph
As first 1 and for fixing the fixed mount 2 of the high-definition camera 1 and certificate.Raspberry Pi master control borad and the power module envelope
In box body 3.
As shown in figure 3, the Raspberry Pi master control borad respectively with the printer and the drive connection of high-definition camera 1, preferably
, printer and high-definition camera 1 are connected by USB port with the Raspberry Pi master control borad respectively.In order to intuitively observe
To the working condition of all parts, 4, two camera indicator lamps 5 and one of a power supply indicator are provided with the box body 3
Individual print indicator 6.And switch key 7 is set on box body 3.
The fixed mount 2 includes bottom plate 21, identity card fixed frame 22 and taking the photograph positioned at the both sides of identity card fixed frame 22
