Embodiment 1
[0027] Please refer to figure 1 , Embodiment 1 of the present invention is:
[0028] A device for identifying instant ticketing through a scratch area, comprising at least one sensor 1 arranged in a line perpendicular to the direction of instant ticketing, the sensor 1 is an infrared sensor, and the wavelength of the infrared light emitted by the infrared sensor is 940nm, the sensor 1 is set on the ticketing path of instant ticketing.
[0029] The infrared sensor with a wavelength of 940nm distinguishes the scratch area and the non-scratch area by the difference in light transmittance or reflectance.
Embodiment 2
[0030] Please refer to figure 1 , the second embodiment of the present invention is:
[0031] A device that recognizes tickets by scratching the area, on the basis of the first embodiment, further includes at least one ticket delivery roller 2, a ticket issuance roller 3, and a ticket breaking knife 4, and the ticket breaking knife 4 is located at the delivery box. Between the ticket roller 2 and the ticket roller 3, the sensor 1 is an infrared through-ray sensor, and the sensor 1 is located between the ticket roller 3 and the first ticket delivery roller 2 along the ticket issuing direction, Preferably, the sensor 1 is located between the ticket feeding roller 2 and the ticket breaking knife 4 .
[0032] When the sensor 1 arrives at the ticket cutting knife 4 when the tail edge of the instant ticket that is about to issue the ticket arrives, it realizes the complete detection of the instant ticket.
[0033] Please refer to figure 2 , a method for instant ticketing through...
Embodiment 3
[0054] Please refer to figure 2 , Embodiment three of the present invention is:
[0055] A method for instant ticketing through scratch area identification, the method is:
[0056] At least one sensor arranged in a line perpendicular to the instant ticket issuing direction detects the boundary point coordinates of the instant ticket scratch area, and stores it as at least one initial array;
[0057] At least one sensor detects the coordinates of the boundary point of the scratch area of the transported ticket and records it as at least one detection array;
[0058] Compare whether the initial array passing through each sensor matches the detection array, and if they match, it is determined that the delivered invoice is correct.
