摘要： Self-luminous barcode readers 102A, 102B, 102C, 102D, 102E, 102F are provided in an arrangement such that irradiating light emitted from the barcode readers 102A, 102B, 102C, 102D, 102E, 102F entirely covers a surface provided with a barcode 107 and optical axes 104A, 104B, 104C, 104D, 104E, 104F of the irradiating light are inclined horizontally at an angle greater than 0° in absolute value and vertically at an angle greater than 0° in absolute value from normal vectors 105A, 105B, 105C of a test surface of a test sample 101 provided with the barcode 107. This arrangement provides a test sample reading device and a test sample reading method with which the success rate of barcode reading can be raised compared to the past.
