Abstract

To read information from a coded record, a record page 1 may be fed past a plurality of aligned reading heads or transducers 2. The reading head 2 may be mounted on a bar 3 which is pivoted by a sector gear 4 until it is aligned with the information on the record page 1.

Skew Compensator

To read information from a coded record, a record page 1 may be fed past a plurality of aligned reading heads or transducers 2. The reading head 2 may be mounted on a bar 3 which is pivoted by a sector gear 4 until it is aligned with the information on the record page 1.

As the record moves under the heads, a guide line 5 is sensed by head A. This causes a ring 6 to advance from start to align, and the align signal causes a bidirectional clutch 7 to engage so that head A follows the guide line 5 of the record. When a head B senses the guide line, the document 1 is in alignment with the head bar 3 and the ring 6 advances to read causing the clutch to disengage. An end of record signal, which would be generated elsewhere, would advance the ring 6 to restore and this would cause the clutch 7 to engage in the opposite direction until the restored contacts were closed, whereupon the ring 6 is advanced to start and the device is then ready for the next record.
