A bar code reading apparatus comprises: a laser module ( 1 ) having a light-emitting device ( 13 ) and a light-receiving device ( 14 ) arranged in a substantially orthogonal state; a moving mirror having a mirror mounted on a stand, swing shafts provided on both sides of the stand, a magnet mounted on a lower side of the stand, a supporting pole arranged below the magnet, and an air-core driving coil in which the supporting pole is inserted; and a light-emitting lens for condensing a light beam from the light-emitting device ( 13 ) and reflecting the light beam to the mirror; the laser module, the moving mirror and the light-emitting lens being housed in a housing. Thus, miniaturization of the reading apparatus is realized, and the bar code reading apparatus is provided in which the light-receiving accuracy is improved while the swing of the mirror is secured.
