Problems solved by technology

At present, the drive-type barcode card reading devices that can read tickets from all sides use laser scanners. The scanning frequency of industrial laser scanners can reach 800 times per second, and the sampling frequency is high. Generally, two scanners are used. The transmission mode can meet the requirements of use, but the cost of the laser scanner is high
The cost of CCD scanner is low, but the scanning frequency is less than 200 times / second, and the card reading efficiency is low
In addition, transmission-type ticket reading has positioning requirements for the ticket card, and generally only tickets with the same width and size can be used

Embodiment Construction

[0013] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0014] As shown in Figure 1, when the barcode card 1 is inserted from the voting port 2, the flip door 4 is pushed to turn over, and the micro switch 3 connected to it is driven to generate an electrical signal, the stepping motor and the scanner 6, 7 are started, and the stepping The motor drives two pairs of rubber wheels 5 and 9 to rotate, and transmits the front end of the barcode card 1 between the scanners 6 and 7, and the upper and lower CCD scanners scan the front end of the barcode card 1, and the stepping motor adopts slow speed during scanning. The speed of the transmission is advanced to adapt to the low scanning frequency of the CCD scanner. If the barcode is just at the front end, the card will be read successfully; Scan between the scanners 6 and 7 to read the barcode. The barcode card 1 continues to move forward under the dri...

Abstract

A card reading device consists of insertion mouth for ticket, induction device and scanner. The scanner gas two CCD scanners set at top and bottom in opposite and a pair of rubber wheel set in front and back of scanner separately for conveying bar code card. The rubber wheel is connected to stepping motor.

Description

technical field [0001] The invention relates to a card reading device for a barcode card, in particular to a barcode card reading device for various tickets, passes and the like. Background technique [0002] The barcode on the ticket is generally printed on both ends of the ticket card, and the four-sided card reading device can ensure that the ticket can be recognized when inserted into the voting slot in any direction. At present, the drive-type barcode card reading devices that can read tickets from all sides use laser scanners. The scanning frequency of industrial laser scanners can reach 800 times per second, and the sampling frequency is high. Generally, two scanners are used. The transmission method can meet the requirements of use, but the cost of the laser scanner is high. The cost of the CCD scanner is low, but the scanning frequency is less than 200 times / second, and the card reading efficiency is low. In addition, transmission-type ticket reading has positioni...
