ABSTRACT:
The present invention relates to a magnetic card reader having a motor driven magnetic head sliding on a stationary magnetic card. An error-checking function for the inserted magnetic card is provided. A control means is provided for setting the start of recording and reading out by the magnetic head at a specific distance from the end of said magnetic card. A position control precisely controls movement of the magnetic head along the magnetic stripe of the magnetic card. The magnetic head is supported by two mutually parallel leaf springs, which hold the head always perpendicular to the magnetic card. A motor governor circuit makes the magnetic head move at constant speed.
