A remote station document reader operating in conjunction with a master control having an array of phototransistors for translating coded data on a document into electrical pulses. The phototransistors are mounted on a carriage movable between a home position and a second position by a motor energized by the insertion of a coded document into the remote station reader. Various checking devices are located in the reader to insure proper orientation of an inserted document prior to reading the coded data. Both coded identification badges and punched hole cards can be read by the reader. When a coded identification badge is in the process of being read, a latch mechanism prevents removal of the badge prior to the code thereon being read.
