ABSTRACT:
In an automatic cassette loading machine a pancake is mounted on a rotatable support hub. A reading member comprising a photoelectric cell and carried by a main carriage movable at right angles to the axis of the pancake is disposed at a position spaced apart from the pancake itself and is then moved close to the latter. When the peripheral edge of the pancake is intercepted by the light beam emitted by the photoelectric cell the reading member is moved away from the pancake and disposed so that it can intercept the passage of a closure tab fastening the end of the tape on the pancake. The pancake rotation is then stopped when the location of the closure tab enables it to be picked up by a grasping member associated with the cassette loading machine.
