An all-directional high-speed laser bar code scanning apparatus comprises a base housing (100). A groove (101) is formed in the middle of the base housing. Three light source open grooves (102-1, 102-2, 102-3) are formed in the periphery of the base housing, and the included angle between every two adjacent light source open grooves is 120 degrees. Three laser diodes (201-1, 201-2, 201-3) are correspondingly fixed in the light source open grooves. Three reflecting mirror brackets (301-1、301-2、301-3) are in one-to-one correspondence to the light source open grooves, each of the reflecting mirror brackets is provided with an emitted light reflecting mirror (302-1, 302-2, 302-3) and a received light reflecting mirror (303-1, 303-2, 303-3), and an opening is formed in the middle of the received light reflecting mirror. A rotary reflecting mirror group (400) is disposed at the central position of the groove. The rotary reflecting mirror group comprises a rotary motor (401) and multiple reflecting mirrors (402) disposed on the side surfaces of the rotary motor. An annular column reflecting mirror group (500) is disposed on the side surface of the boundary of the groove. Three light receiving open grooves (601-1, 601-2, 601-3) are formed below the rotary reflecting mirror group, and the included angle between every two adjacent light receiving open grooves is 120 degrees; a photosensitive receiving tube is disposed on each of the light receiving open grooves. The all-directional high-speed laser bar code scanning apparatus has the advantages of a wide scanning range, a high scanning speed, a large quantity of lines, a good bar code identification effect and the like. |
