Abstract: A transfer device is provided that ensures transfer of information carriers of different dimensions due to a single loading device including a detection mechanism means (32) associated with linking elements (40). Upon the insertion of an information carrier, the linking elements (40) cooperates with a projection (50A, 50B) set in relation with the size of the inserted information carrier. The projection is supported by a slider (52) that actuates clamping and driving mechanisms to ensure the setting of the inserted information carrier in its operative position. Thus, the synchronization between the clamping and driving mechanisms is made in relation with the size of said carrier.

Abstract: A loading device for loading an information carrier into a recording/playback unit is provided. The loading device includes a pair of gripping elements that are actuatable to grip the information carrier therebetween. A transport mechanism moves the gripping elements during the loading of the information carrier. The gripping elements are supported by the transport mechanism for movement relative to the transport mechanism. A control mechanism is provided for actuating the gripping elements when the gripping elements are moved by the transport mechanism.

Abstract: A food product cartridge comprising a delivery and dosage member, said cartridge having a base part wherein an endless screw and a delivery opening are housed, characterized in that the endless screw is provided to operate a shutter for opening and closing the delivery opening.

Abstract: A cartridge housing for a recording disc has a thin, flat, substantially circular shape and includes a cover and a bottom at least one of which has an aperture allowing access by a reading or recording head of a reading/recording unit to a recording surface of a contained disc. A flat shutter is pivotally mounted around a shaft inside the cartridge housing for movement between aperture-closed and aperture-open positions responsive to limited relative rotational movement of the cover and bottom. An actuating leg extending from the shutter adjacent an edge diametrically opposite the shaft location cooperates with a arcuate chamber in the adjacent peripheral edge of the cover to move the shutter between the aperture-closed and aperture-open positions.
