Abstract

The invention relates to a barcode reading device, comprising a housing, a slot-shaped viewing window with openings at both ends, a camera module and a circuit board arranged in the housing, a hole is arranged on the front of the housing, and the slot-shaped viewing window Set in the hole; the depth value D of the slot-shaped viewfinder window 1 ≥10mm, the lens of the camera module captures the barcode image through the slot-shaped viewfinder, and then transmits it to the processor on the circuit board for decoding to obtain the barcode information. The barcode reading device of the present invention effectively blocks stray light from entering the lens through a deep slot-shaped viewing window and undulations on the side wall of the slot-shaped viewing window, thereby realizing long-distance capture of clear barcode images.

Description

technical field

[0001] The invention relates to a barcode reading device, which belongs to the field of barcode identification. Background technique

[0002] The barcode scanning methods of existing barcode recognition equipment are roughly divided into the following two types: 1. Active code scanning: the merchant holds a barcode scanner to scan the barcode presented by the user. The angle of the gun enables the camera to capture a clear barcode image, but this method must be manually scanned, which cannot meet the needs of unmanned scanning codes such as toll stations, parking lots, etc.; 2. Passive code scanning: the barcode recognition device is fixed Manually, the user holds the mobile terminal, closes the identification code on the mobile terminal or approaches the lens of the barcode reading device at a relatively short distance, and adjusts the barcode from multiple angles. Otherwise, the success rate of reading is low and affects the user experience. When the passi...

Embodiment Construction

[0045] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0046] see Figure 3 to Figure 5 , a barcode reading device, comprising a housing 1, a slot-shaped slot-shaped viewing window 4 with openings 42 and 43 at both ends, and a camera module 2 and a circuit board 3 arranged in the housing 1, the housing 1 The front side 11 is provided with a hole 12, and the slot-type viewfinder 4 is sleeved in the hole 12; the depth value D of the slot-type viewfinder 4 is1 ≥10mm (see Figure 17 ), the lens 21 of the camera module 2 captures a barcode image through the slot-shaped viewfinder 4, and then transmits it to the processor 31 on the circuit board 3 for decoding to obtain barcode information. The barcode information can be transmitted externally through the data transmission interface 33 on the circuit board 3, or wirelessly transmitted externally through the wireless communication module. The deep slo...
