When the card medium 101 moves toward the scanning mechanism 100, the guide groove 170 can limit and guide the card medium 101, so that the medium can move more smoothly to the area between the two step ribs 161.
The workflow of the scanning mechanism 100 may be as follows:
referring to fig. 5, a block diagram of a first cross section of a scanning structure according to an embodiment of the present invention is shown; referring to fig. 6, a partial structure block diagram of a first cross section of a scanning structure according to an embodiment of the present invention is shown. A media card (i.e., card media 101 such as a bank card, membership card, identification card, etc.) to be scanned is inserted from the guide slot 170; when the media card front starts to occlude the first sensor 1321; the power motor receives a signal (which may be generated and sent directly by the first sensor 1321 or may be sent by the control module), and the motor is started; the transmission roll shaft rotates; as the media card enters the first drive roller assembly 140, it is driven forward by the frictional force generated by the pressure of the first upper floating roller (first upper drive roller 142); here, a gap of 0.5mm (a first preset gap) is required to be designed between the lower driving roller (the first lower transmission roller 141) and the upper floating roller; (since a normal media card thickness is about 0.8-1.0 mm; without a gap the media card would jam due to too much pressure). The medium card continues to be driven forwards, at the moment, the medium card is positioned between the upper step rib 161 and the lower step rib 161 (the step rib body assembly 160), and the upper step rib 161 and the lower step rib 161 play a role in limiting the two sides of the medium card; ensuring that the media card does not incline left and right; when the media card front begins to obscure the second sensor 1322; the CIS scans the received signal (the signal can be directly generated and sent by the second sensor 1322 or can be sent and obtained by the control module), the CIS starts to scan; when the rear end of the media card shields the third sensor 1323, the CIS scanning stops working; finally, when the back end of the media card shields the fourth sensor 1324; the media card scan is complete and advances away from the scanning mechanism 100.
Referring to fig. 7, a structural block diagram of a second cross section of a scanning structure according to an embodiment of the present invention is shown; referring to fig. 8, a partial structure block diagram of a second cross section of a scanning structure according to an embodiment of the present invention is shown. If the paper medium 102 (for example, a4 paper) is to be scanned, the lower driving roller (the second lower driving roller 151) and the upper driving roller (the second upper driving roller 152) on both sides of the step rib body assembly 160 need to be designed to have no gap and overlap by 1.0mm as shown in fig. 7 and 8 (in practice, the second lower driving roller 151 and the second upper driving roller 152 are attached to each other and cannot overlap with each other), it should be noted that when the top cover 120 and the base 110 are closed and no medium exists between the second upper driving roller 152 and the second lower driving roller 151, the second elastic assembly is compressed by 1 mm; because the thickness of the conventional paper-like medium 102 is 0.1-0.2 mm; the gap may cause insufficient friction with the paper-like medium 102 and the paper-like medium 102 may not be driven forward. For the paper medium 102, the inclination detecting sensor assemblies 133 arranged on both sides of the step rib body assembly 160 can determine the inclination of the edge of the medium and the moving direction of the medium, and when the inclination is greater than a certain threshold, the second lower driving roller 151 stops transferring the medium, and the scanning mechanism 100 sends out corresponding prompt information.
