    摘要: A data-processing machine having a single operator station is provided with a printer comprising a supply holder on the front of the machine next to the operator station for holding a form band, a support on the machine next to the station with an upwardly concave surface, and a receptacle on the back of the machine below the support for catching the printed form band. A guide and a transport device is provided for guiding the band up from the supply holder in the front of the machine, over the surface of the printing station and down to the receptacle. A printing head which is vertically displaceable above the upwardly concave surface is displaceable horizontally along the surface to print the band. A guide slot extending down toward the supply is pivotal between a down position for normal operation of the machine and a raised position for threading a new form band in and a detent is provided for holding it in the up position during reloading. In addition, a magnetic-card printer is provided on the machine adjacent the operator station. Feelers engageable with the band detect when it runs out and emit an alarm for the operator.
