EINRICHTUNG ZUM SPEICHERN ELEKTROMAGNETISCHER STEUERSIGNALE UND MIT DIESER EINRICHTUNG AUSGESTATTETER TONFILMPROJEKTOR

摘要

A circuit for storing a control signal on a selected length of strip material such as a magnetic tape having a tape head associated therewith and provided with longitudinally spaced marking signals. The circuit includes a control signal generator arranged to be switched on by a control unit to produce a control signal which is applied to the selected length of strip material, and a first detector responsive to the marking signals for switching off the control signal generator when a marking signal is sensed in one direction of movement of the tape material together with a second detection responsive to the stored control signal for switching on the control signal generator during the movement of the tape in the other direction to store the control signal throughout the selected length of strip material, the first detector switching off the control signal generator when the other marking signal is sensed by the first detector.
