Abstract

A reader for reading magneto-optical characters, with the options of printing them or storing them. A track is provided for driving a check from an inlet plate (T1) over various portions of path (T2, T3 and T4). Wheels (G1 and G2) are provided beneath the path, and may be motor driven. Above said wheels there are heads (TM1 and TM2) respectively for premagnetizating and reading CMC7 characters. Each head is mounted on one arm of a corresponding bell crank (L1, L2) which cranks are pivoted to a frame at their corners (L10 and L20). The other arm (L12 and L22) of said bell cranks are resiliently urged by springs (L15 and L25) mounted on an actuator rod (AC) which is itself driven by an electromagnet (EM2). It has turned out that such an assembly ensures effective transducer operation of the heads (TM1 and TM2) for reading CMC7 characters.
