Abstract

A container for an interchangeable cassette comprises a casing having a frame-like slide therein which engages the cassette. For removal of the cassette from the casing, a spring urges the slide and cassette outwardly and the arrangement is such, that in the open position of the slide, at least that part of the slide which protrudes from the casing assumes an oblique position relative to the casing and cassette to allow the cassette to be removed directly from the casing. The slide may include tape hub-engaging bosses to prevent tape spillage.

Claims

1. A container for a tape cassette comprising:

a rectangular casing having flat top wall, bottom, two parallel narrow side walls, rear wall and a front opening;

a cassette-moving push-in slide in the form of a four-sided open-bottom frame, fitting and movable inwardly and outwardly within said casing through said opening between closed and open positions, the two side parts of said frame extending along said narrow side walls of said casing and which frame at least partially surrounds the periphery of a tape cassette lying on said casing bottom;

spring means engaged between said casing and said frame which, after a holding device is unlocked, will propel said frame together with a tape cassette, which will slide therewith along said casing bottom, a certain distance through said front opening into said open position;

guide means for controlling the movement of said frame which are designed in such a way that, in said open position, at least that part of said frame which protrudes from said casing assumes an oblique position relative to said bottom of said casing so that a tape cassette which lies on said bottom of said casing and protrudes therefrom, is at least partially exposed.

2. The structure defined in claim 1 wherein:

the frame has a front wall which closes the front opening of the casing; and

frame is supported on the bottom of said casing by the lower edges of its side parts;

the guide means during initial movement of said frame from closed to open position maintains said frame parallel to said bottom of said casing and subsequently allows movement into the oblique position; and

a front part of said frame which protrudes from said casing in said open position has a smaller length than that part of said frame which remains within said casing.

3. The structure defined in claim 2 wherein a part of the frame is designed to be capable of a swivelling motion within the casing, and including at least one stop which is located on said casing, is in a zone above the locus of the force of the spring means, and is engageable by the rear wall of said frame when the latter is in the open position to move said frame into the oblique position.

4. The structure defined in claim 3 wherein the casing stop is located on the top flat wall of the casing and including chamfered sections on the upper edges of the side parts of the frame in the zone of that part of said frame which remains within the casing, which sections rest, when in the open position, against said top wall of said casing and define the angle of the oblique position of said frame versus the bottom of said casing.

5. The structure defined in claim 1 wherein the container is designed for stowing and removing a music tape cassette in all its four elongate orientations.

6. The structure defined in claim 5 wherein the frame is provided along its central axis with two lugs spaced apart a distance corresponding to the spacing between centres of the capstan holes of tape cassettes, which lugs extend perpendicular to the bottom of the casing when in the closed position and are so located and designed that they protrude and fit into that hole zone of the capstan holes which is overlapped by another hole when the position of a cassette is turned about the londitudinal axis of the cassette.

7. The structure defined in claim 6 wherein the rear lug, when in the closed position, is located between the casing stop and the rear wall of the frame and when in open position, is removed from the capstan hole zone.

8. The structure defined in claim 7 wherein, when in the closed position, the casing stop is located immediately in front of the rear lug, and said lug is mounted on a bracket which is fixed to the rear wall of the frame and rests resiliently on a cassette in the capstan hole zone.

9. The structure defined in claim 3 wherein:

the lower edges of the frame side parts each consist of a rear section by which the frame rests on the casing bottom in the closed position, and a chamfered front section extending in a rising straight line to the front wall of said frame and forming a tapered slot with the bottom of the casing;

a front part of said frame, which protrudes from said casing in the open position and has said lower front section edges, has a flat web extending between the upper edges of said side parts;

a recess is formed at the front end of the top wall of said casing and extends between the side walls, said recess exposing the front portion of said web in the closed position of said frame; and

a holding device is engaged between said web and said top wall of said casing, which holding device is unlocked by pressing down said exposed front portion of said web and elastically narrowing said tapered slot.
