Detailed description of the invention
Fig. 1 is the structural schematic diagram of turnover mechanism of the invention.
Specific embodiment
To make the objectives, technical solutions, and advantages of the present invention clearer, right in the following with reference to the drawings and specific embodiments
The present invention is described in detail.
Refering to Figure 1, the double-faced scanning device provided in this embodiment based on single CIS sensor, including transmission
Mechanism, sweep mechanism and turnover mechanism, sweep mechanism are located on the transmission line of transport mechanism, and transport mechanism connects turnover mechanism
Card entrance, turnover mechanism include upper returning face plate 1, lower returning face plate 2, at least two pairs of rub wheel groups 3, rotary drive motor 4 and installation
Rub wheel driving motor 5 on lower returning face plate 2；Each rub wheel group 3 include upper rub wheel to 3-1 and with lower rub wheel to 3-2, each upper stranding
Wheel is socketed in the through-hole for turning over rotating plate 1 wheel shaft of 3-1, and each lower rub wheel is socketed on the through-hole of lower returning face plate 2 to the wheel shaft of 3-2
Interior, the upper rub wheel of each pair of rub wheel group is to 3-1 and lower rub wheel to the channel constituted between 3-2 for inhalation scintigraphy part, channel and biography
The transmission line of mechanism is sent to be located at same horizontal line, each lower rub wheel is sequentially connected between the wheel shaft of 3-2 by lower transmission belt 6,
The transmission axle of rub wheel driving motor 5 is sequentially connected to the wheel shaft of 3-2 by driving transmission belt 7 and lower rub wheel；Upper returning face plate 1 with
Torsion shaft 8 is respectively equipped on lower returning face plate 2, one end of each torsion shaft is fixed on rotation gear 9, and rotation gear 9 and rotation are driven
The drive shaft of dynamic motor 5 is connected by meshing transmission.
Below by each mechanism in above-mentioned apparatus composition and the method for operation etc. be described in detail:
Through-hole on upper returning face plate 1 is distributed in horizontal interval, the through-hole on the corresponding upper returning face plate of the through-hole on lower returning face plate 2
Horizontal interval distribution.
Device further include it is non-connect card reader mechanism, the non-card reader mechanism that connects is located on the transmission line of transport mechanism, card outlet
It is connected with the card entrance of sweep mechanism.
Transport mechanism includes driving stepper motor, belt and gear set, and stepper motor is driven to drive gear set by belt
