Abstract

A numbering box for a press for printing bank notes has a stack of sensor boards in one-to-one correspondence with a stack of numbering wheels and each of the boards has an edge area at the printing face of the numbering box which carries an LED indicator of a status of magnetic signalling means on the respective numbering wheel. The boards are each connected to a motherboard in the numbering box. Data processing means in the numbering box may be connected to a remote computer by an optical fibre link. The sensor boards are closely spaced and each has an aperture to accommodate a bulky component of the or an adjacent board.
