Abstract

An adaptive scanning device, used to meet requirements for scanning and recognizing different scanned media and to save time and scanning costs. The adaptive scanning device in an embodiment of the present invention includes: a left side plate, a right side plate, an extension spring, an upper floating channel assembly, an image scanning tube B, a lower channel plate, a card information reading assembly, a document information reading assembly, friction wheels and a shaft sleeve. The upper floating channel assembly specifically includes: an image scanning tube A, an upper channel plate, an upper channel fixed shaft and fixed bearings.

First claim

What is claimed is:

1. A self-adaptive scanning device, comprising:
a left side plate, a right side plate, a tension spring, an upper floating passage assembly, an image scanning tube B, a lower passage plate, a card-type information reading assembly, a certificate information reading assembly, friction wheels, and shaft sleeves, wherein
the upper floating passage assembly comprises an image scanning tube A, an upper passage plate, an upper passage fixed shaft, and fixed bearings;
the upper passage fixed shaft is fixed to the upper passage plate, and is mounted between the left side plat and the right side plate;
the left side plate and the right side plate are each provided with a guide slot, and each of the shaft sleeves is movably mounted in the corresponding guide slot and slides upward and downward along the respective guide slot, and two ends of the upper passage fixed shaft are fixed to the shaft sleeves respectively;
a plurality of fixed bearings are mounted on the upper passage plate, and a plurality of friction wheels are mounted on the lower passage plate, and the fixed bearings and the friction wheels are arranged in pairs;
a scanning passage between the upper passage plate and the lower passage plate is formed;
the image scanning tube A is mounted above the scanning passage, and the image scanning tube B is mounted below the scanning passage;
the tension spring has one end fixed to the upper passage fixed shaft, and another end fixed to the left side plate or the right side plate;
the card-type information reading assembly is mounted on the upper passage plate or the lower passage plate, and is configured to read a built-in card information of a card type scanned medium in the scanning passage; and
the certificate information reading assembly is mounted on the upper passage plate or the lower passage plate, and is configured to read a built-in certificate information of a certificate type scanned medium in the scanning passage.

2. The self-adaptive scanning device according to claim 1 , further comprising a reversing mechanism, wherein
the reversing mechanism comprises a rotational electromagnet, a coupling, a reversing spindle, and a reversing component;
the rotational electromagnet and the reversing spindle are fixedly connected together by the coupling;
the rotational electromagnet is mounted on the left side plate or the right side plate; and
the reversing component is fixedly mounted on the reversing spindle.

3. The self-adaptive scanning device according to claim 2 , wherein
the reversing component is driven to rotate by the rotation of the rotational electromagnet, and the reversing component, after being rotated to move upward, meshes with a vacant slot mated with the reversing component in the upper passage plate, and a joining passage between the reversing component and the lower passage plate is formed; and
after the reversing component rotates to move downward, a front end of the reversing component abuts against the lower passage plate, and a recovering passage between the reversing component and the upper passage plate is formed.

4. The self-adaptive scanning device according to claim 1 , wherein the self-adaptive scanning device further comprises:
a plurality of transmission shafts passing through axes of the friction wheels respectively and mounted between the left side plate and the right side plate, with each being configured to drive the friction wheels on the transmission shaft to rotate together.

5. The self-adaptive scanning device according to claim 4 , wherein the self-adaptive scanning device further comprises:
a driving wheel fixedly mounted at one end of each of the transmission shafts and located on an outer side of the left side plate or the right side plate;
a caterpillar band, mounted around a plurality of driving wheels, and configured to drive the driving wheels to synchronously rotate; and
a driving motor, mounted to the left side plate or the right side plate, wherein the driving motor is provided with output wheels, the output wheels are connected to the driving wheels by the caterpillar band, and the driving motor drives the plurality of driving wheels to rotate via the output wheels and the caterpillar band.

6. The self-adaptive scanning device according to claim 1 , further comprising: an upper cover of housing and a lower cover of housing matching with the upper cover of housing, wherein,
the upper cover of housing and the lower cover of housing are movably connected by a hinge; and
the self-adaptive scanning device is housed by the upper cover of housing and the lower cover of housing together.

7. The self-adaptive scanning device according to claim 3 , further comprising a recovery box, wherein
the recovery box is mounted at an exit of the recovering passage, and is configured to recover the scanned medium coming out from the recovering passage.

8. The self-adaptive scanning device according to claim 1 , wherein
when the scanned medium enters the scanning passage, the upper passage plate slides to move upward under the action of a supporting force of the scanned medium, and the scanned medium enters the scanning passage; and
the upper passage plate slides downward under the action of a restoring force provided by the tension spring and closely fits the scanned medium, to allow a sensing surface of the image scanning tube A on the upper passage plate and a sensing surface of the image scanning tube B on the lower passage plate to fit an upper surface and a lower surface of the scanned medium respectively.

9. The self-adaptive scanning device according to claim 7 , wherein
the scanned medium, after entering via an entrance of the scanning passage, passes through the scanning passage to enter the recovering passage, and finally enters the recovery box via an exit of the recovering passage, during this period, the image scanning tube A scans the scanned medium, or the image scanning tube B scans the scanned medium, or the card-type information reading assembly reads related information of the scanned medium, or the certificate information reading assembly reads related information of the scanned medium.

10. The self-adaptive scanning device according to claim 7 , wherein
when the scanned medium enters via an entrance of the joining passage, the reversing mechanism moves upward, and the scanned medium passes through the joining passage to enter the scanning passage, and finally comes out via the entrance of the scanning passage.
