Abstract: This invention relates to display units for cassettes and like articles.The display unit comprises a vertical support spindle on which is rotatably mounted a plurality of spaced trays. Display sections are formed by adjacent trays for receiving the cassettes and the cassettes are released by axial movement of the adjacent trays on the support spindle.According to the invention adjacent trays are rotatable relative to each other to produce the necessary axial movement and locking means is provided along the length of the spindle to prevent unauthorized operation.

Abstract: The invention relates to a unit for displaying cassettes and tape cartridges. The unit is pivotally mounted about a fixed support and comprises one or more radially extending display sections each of which is adapted to receive the cassettes in a slidable manner in the radial direction from the ends of the arms forming the display section. Unauthorised removal of the cassettes is prevented by a locking device which may be positioned under the control of a locking mechanism across the plane of withdrawal of the cassette from the arms of each display section. The locking device may comprise a relatively rotatable frame incorporating locking bars. In an alternative arrangement a locking rod may be positioned in the arms for vertical or horizontal movement under the control of a locking mechanism. The locking rods may also be angularly movable.
