Abstract

A device for the optical-electrical scanning of an information carrier with a scanning device especially for use with a knitting machine having at least one lamp, at least one photoelectric cell, a transport means for establishing relative motion between the information carrier and the scanning device, including a control circuit to maintain a preselectable rated intensity in said lamp, a voltage limiting circuit for the lamp voltage, a first time member associated with said voltage limiting circuit through which the lamp voltage during the switch-on process is at first limited to a value above the preselected lamp voltage and a preselected time span after the switch on process to nominal lamp voltage and that the transport means is activated after attainment of a rated intensity.
