Abstract
Abstract A bar code scanner which is responsive to the movement of the scanner to activate its light source. The scanner includes a motor having a moving member which is set in motion when the scanner is displaced from a rest position. The moving member generates a voltage in a coil, which activates the operation of the bar code scanner.
