A barcode reading apparatus has a scanner unit for reading barcodes and a processor for controlling whole operation of the apparatus. The barcode reading apparatus judges whether a distance between a operation unit for receiving an instruction to be given by a user and an operating body such as the finger of the user falls with in a prescribed range, and starts up and brings the scanner unit to a standby state, when it is determined that the distance between the operation unit and the operating body falls with in the prescribed range, and waits for an instruction of making the scanner unit start reading barcodes.
