    摘要： A device for driving a flexible strip provided with two rows of regularly spaced lateral perforations. This device includes a first slider to which is imparted a first reciprocating movement back and forth parallel to the direction of said strip, a second slider which moves with the first slider as far as the first reciprocating movement is concerned, but to which is also imparted a second reciprocating movement with respect to the first slider, a hinging plate mounted to pivot on the first slider and carrying claws each of which may cooperate with a perforation in one of the said lateral rows, and means enabling the said hinging plate to be moved towards or away from the second slider.

    摘要： A device for controlling at least one magnetic head in an apparatus for writing and reading data on and out a magnetic medium. Said device is equipped with a spindle actuating at least one cam cooperating with at least one arm equipped with a spring attached by one of its ends to this arm and by the other end in contact with the magnetic head in such a way as to be capable of bringing said magnetic head near said medium into a position for writing or reading said data, a device for controlling the rotation of said spindle, means for locking the magnetic head in said position and means for releasing the magnetic head, so that it may be moved away from said medium. Said device is utilizable with magnetic disk memories.
