Abstract
PURPOSE: To enable to read in with the bar code incoming to any slope of the weight carrying surface, by forming the image of read-in body on the photo electric conversion surface of two dimensional photo diode.
CONSTITUTION: When the read-in body sticked on the commodity or larggage 1 moves on the laggage carrying surface 12 such as conveyor, the bar code 2 is made to the bar code image 4 with the lens 3 through the read-in opening. The two dimensional photo diode image sensor 5 is located on the surface of the bar code image 4, video signal is picked up as electric signal, this sensor 5 is driven with the address indicated with the control circuit 7 by the drive current 6 so that the signal 12 can be picked up, the code signal converted into electric signal is amplified at the amplifier 9 and outputted at the output terminal 8 via the control circuit 7 and stored in ROM11, enabling to read in the bar code 2 in any direction.
