Brief description of the drawings
Fig. 1 is the structural representation of the switching mechanism of the present invention.
Embodiment
In order that the object, technical solutions and advantages of the present invention are clearer, below in conjunction with the accompanying drawings with specific embodiment pair
The present invention is described in detail.
Refer to shown in Fig. 1, the double-faced scanning device based on single CIS sensors that the present embodiment is provided, including transmission
Mechanism, sweep mechanism and switching mechanism, sweep mechanism are located on the transmission line of transport mechanism, transport mechanism connection switching mechanism
Card entrance, switching mechanism includes upper returning face plate 1, lower returning face plate 2, at least two pairs rub wheel groups 3, rotary drive motors 4 and installed
Rub wheel motor 5 on lower returning face plate 2；Each rub wheel group 3 includes upper rub wheel to 3-1 and with lower rub wheel to 3-2, each upper stranding
Take turns and 3-1 wheel shaft is socketed in the through hole of upper returning face plate 1, each lower rub wheel is socketed on the through hole of lower returning face plate 2 to 3-2 wheel shaft
Interior, the upper rub wheel of each pair rub wheel group is to 3-1 and lower rub wheel to constituting the passage for inhalation scintigraphy part between 3-2, passage is with passing
Send mechanism transmission line be located at same horizontal line, each lower rub wheel to being connected between 3-2 wheel shaft by lower transmission belt 6,
The transmission axle of rub wheel motor 5 is by driving transmission belt 7 to be connected with lower rub wheel to 3-2 wheel shaft；Upper returning face plate 1 with
Trip shaft 8 is respectively equipped with lower returning face plate 2, one end of each trip shaft is fixed on swing pinion 9, swing pinion 9 drives with rotation
The drive shaft of dynamic motor 5 is connected by meshing transmission.
Composition and the method for operation of each mechanism in said apparatus etc. will be described in detail below：
Through hole on upper returning face plate 1 is distributed in horizontal interval, the through hole level on the upper returning face plate of through hole correspondence on lower returning face plate 2
It is spaced apart.
Device also includes Fei Jie Card Readers mechanism, and Fei Jie Card Readers mechanism is located on the transmission line of transport mechanism, the outlet of its card
It is connected with the card entrance of sweep mechanism.
