Abstract: A housing has an opening for receiving supports for audio or video cassettes or discs. When the support is fully inserted in the housing, an elastic bias member in the housing exerts a force on the support in a direction which is substantially transverse to the insertion direction. The elastic bias member yields in response to manual pressure on the support which turns the support through an angle in a first rotational direction to a pivoted position. When the support is in its pivoted position, the elastic bias member moves the support to an ejection position while rotating the support in a second rotational direction which is opposite to the first rotational direction. A plurality of housing modules with such elastic bias members are connected together by snap connectors for storing a plurality of supports for recording media.

Abstract: Sharpener press-button is disclosed comprising a tubular body having one open end and another end closed by a transverse wall. The transverse wall is formed on its outer surface with an extension cooperative with a propelling pencil for fixing thereto a button. The button has a blade element including a central portion provided with an opening, two lateral converging flanks extending from the central portion and the two ends of the flanks remote from the central portion extending parallel and together in the direction away from the central portion. The blade element is housed within the tubular body, with the ends inserted into a recess in the inner face of the transverse wall and the central portion adjacent the open end of the body, the lateral flanks being formed with cutouts extending in the axial direction of the button and tapered in the direction away from the central portion of the blade element, the button having at least one radial penetrating aperture.
