Arrangement for detecting an opaque label area on a transparent envelope

摘要

For use together with a device for detecting a plurality of information positions where postal information pieces are described, an arrangement is for detecting one of the information positions that is described on an opaque label attached to a transparent envelope. Responsive to a regularly reflected beam from the opaque label, a label positon detector detects a label position where the opaque label is attached to the transparent envelope to produce a label position signal representative of the label position. Responsive to the label position signal, a selector selects the above-mentioned one of the information position.
