  • Patent number: 4145727
    Abstract: The cassette receiving chamber in a cassette tape recorder is constructed on a movable support that can elevate and lower the cassette into and out of the operating position while maintaining the cassette in a stable constant orientation. It is constructed of two substantially identical U-shaped elements that cross legs in shifting the chamber in the fashion of scissors.

  • Patent number: 4043149
    Abstract: Uniform load clutch device for transmitting a motion from a driving member to a driven member while permitting friction slippage between the two members should the driven member be stopped, wherein the driving member has a cylindrical part on which are freely mounted first and second friction pads with the driven member interposed therebetween, and resilient biasing means mounted on said cylindrical part and locked thereon in operational position exerting a force to bring into firm engagement said members and friction pads, whereby no relative movement will take place between said resilient biasing means and said driving member during the transmission of said motion.

  • Patent number: 4023870
    Abstract: A device for centering and fastening a flywheel of a cassette-type recorder to the wall of the recorder housing, comprising a cylindrical sleeve connected to said flywheel and having an annular member with a torus-shaped periphery fixed on said sleeve, a bush mounted on said wall having an inner cylindrical surface of such diameter and axial extension to receive said sleeve and annular member, and resilient retaining means mounted on said bush and protruding from said inner cylindrical surface, said retaining means having a diameter less than said torus-shaped periphery capable of resiliently yielding to allow said periphery to pass when the latter is forced against said retaining means by an axially directed force, and snapping again into its protruding position after said periphery is passed.
