ABSTRACT:
A readout cassette comprises a preferably two-part plastic casing in which two coil shafts are rotatably mounted. The coil shafts serve to receive a thin paper web or the like printed on at least one side. The web is unwrappable manually by means of a rotary knob or through the intermediary of an electric drive from one coil shaft to the other and vice versa in opposite directions behind two readout panels. The readout panels consist of a highly transparent plastic material and cover viewing apertures provided on the front and rear sides of the casing.
