The bar code reader for reading the bar code at any angles includes a number of mirrors (4,4'-5,5') placed at the corresponding positions to the bar codes (1) to reflect the laser, a reader (9) adjusting a sensor (10) to 0-180 degrees by a position control motor (6), a discriminator (7) discriminating the read bar code, and a motor controller (8) controlling the position motor on the discriminator signal.
