Abstract: A container for holding a cassette that includes a rectangular casing into which a cassette can be directly inserted and stored and a frame-like bottomless slide which is positioned in the casing and selectively operated for moving the cassette into and out of the casing. An hourglass-type spring is positioned between the slide and casing to urge the slide to an upwardly extended cassette-exposing position. A selectively releasable locking mechanism for retaining the slide in a cassette-storing position includes a finger pressure contact indentation formed in the front wall of the slide and double-latch locking projections formed on the front of the slide and casing at opposite sides of the finger pressure contact indentation. Hublock projections formed on the slide engage the hub-openings of a stored cassette only when the slide is in its cassette-storing position.
