The cassette 10 shown in FIGS. 1 to 4 has a flat bottom 11 made of plastic or an an-CR In light, durable material., Am Boden 11 i-; jine back wall 12 made of the same material- · igt, for example by gluing or as attached -.hmolzene continuation of the bottom 11. With the parts 11 and 12 is also a previous cover part 13 i-jrbunden, who with them a three-sided wrap t-'iidet. The cover part 13 can be fastened with screws 14. 15 on the back part 12 and with screws 16. 17 and 18 with posts 119, 20 and 21, which in Fig. 3 au the front of the cassette are shown. \ be screwed. The posts 19, 20 and 21 serve as a spacer ^ . Aischen cover part 13 and bottom part II.

With the aid of a spring hinge 23 which is attached to the open side of the rear part 12. is a first L-shaped part 22 stored so that tine side and a -I part of the front of the housing described so far is closed from parts 11, 12 and 13, A second L-shaped part 24 is in the same way via a spring hinge 25 on the other open side of the Rücktciles 12 attached so that the other side and the remaining part of the front of the Housing is lockable. According to FIG. 1 can do the Front edges of the parts 22 and 24 should be worked out so that the end 26 of the part 24 into the end 27 of part 22 engages, as shown by the dashed line 28, so that a solid flush front wall du " Cassette 12 is created. The parts 22 and 24 can be made of light metal or other durable material.

The upper part 13 includes a pair of openings 29 and 30 which are formed with collars 31 and 32 respectively, which, as shown in FIG. 3, protrude into the interior of the cassette. As will be explained in more detail, serve the collars 31 and 32 holding a pair of reels 33 and 34 inside the cassette 10. The openings 29 and 30 allow access / u the coils and 34 through the collars 31 and 32 for driving the Reels from the outside of the cassette 10. In the upper part 13 is also a pair of openings 35 and 30 arranged, which allow access to a releasable lock in each case. In the illustrated Embodiment, leaf springs 39 and 40 with rivets 37 and 38 are attached to the underside of the part. 4 shows that a U-shaped catch 41 is attached to the inner surface of the part 24 which cooperates in the closed position of the cassette with the spring 39 and the part 24 holds on. Correspondingly, a catch 42 on part 22 cooperates with spring 40.

The upper part 13 also has a pair of incisions 45 and 46, which correspond to the one to be described Purpose of allowing access to the cassette 10 from the outside. On the inner surface of part 24 is a ίο wedge-shaped metal part 47 attached, which when closed Cassette 10 protrudes under part 13 and provides dust protection at recess 45. In In the same way, a wedge-shaped metal part 48 is provided on part 22 as a dust protection for recess 46.

Of the numerous possibilities for storing the reels 33 and 34 within the cassette, a pair of circular, raised rings 50, 51 is provided on the bottom part 11 in the embodiment of FIG. The coil 33 is rotatably mounted between the collar 3t and the ring 50; the same applies to the coil 34 with regard to the collar 32 and the ring 51. The rings 50 and 51 can be in the form shown in FIG. 5 and have a shoulder 56 which holds the reels 33 or 34 in place when they are rotated. At the end of a pin 53, a ring 52 is held by a clamping device 55 within the part 56 and protrudes upwards into the center of the coil 33, a spring 54 pushing the ring 52 upwards. The collar 31, the spool 33 and the ring 50 are designed so that when the spool 33 rotates freely, a frictional force is exerted on them which counteracts a movement of the spool. If a drive device, not shown, is introduced into the coil 33 through the opening 29, a downward force is exerted against the spring 54, which causes the coil to rotate with minimal friction. The coil 34 can interact with the collar 32 and the ring 51 in the same way.

Line typical tape guide within the cassette 10, which according to the F i g. 1 to 4 is constructed. is shown in FIG. The back part 12 can be formed with a curved contour and thereby the match the two coils 33.34. The tape material is at one end on the core of the spool 33, with the other end attached to the core of the coil 34. The remaining part of the tape 60 is on the reels 33, wound up. When the belt 60 moves between the two reels 33, 34, it runs on a web 61. which is fixed between parts 11 and 13, on further webs 19, 20 and 21, which are shown in FIG are, and past a web 62 fastened between the parts 13 and 13.

55 By this construction, a cassette is formed, which a storage of the tape according to the Fig. 1 and 2 allows the tape to be completely closed and is protected. When the cartridge and the tape it contains are to be used. 60 one exerts a pressure through the openings 35 and 36 on springs 39 and 40. so that the side parts 22 and 24 are released and as a result of the claw the spring joints 23 and 25 in the F i ü. and 4 unfold the position shown. You can then: 65 can easily reach the belt 60.

The cassette 10 is suitable for numerous applications, for example for the one shown with reference to FIGS. The use of quadru-

plexf emsehmagnetic tape devices is known. It is now assumed that the inventive cassette 10 to be used for such a recording device. In this case it becomes a piece two inches wide Magnetic tape wound around reels 33 and 34. The cassette 10 is in a not shown, suitable Holder arranged, and the side panels 22 and 24 are opened so that the tape is exposed when it over the webs 61. 19, - 20, 21 and 62 in the in the F i g. 3 and 6 runs in the manner shown. Through the cutouts in part 13, a pair of rods 70 and 71 introduced, which in a mechanical manner, as indicated by the dashed lines 73, 74, can be moved by a drive 72. The cutouts 45 and 46 and the bars 70 are selected in this way • and 71 inserted through them so that they are inside the tape loop in the cassette 10. At the same time occurs a drive device in the form of suitable waves, which through the dotted Lines 75 and 76 are shown and driven by a drive device 77 by the openings 29 and 30 engage the coils. Here, the waves are used to create a coil, for example the coil 34, while the other coil 33 is free or against a tensile force can turn. Although not shown in detail, the coils are built to work with the Drive means 75, 76 fit together and can be rubbed in the manner described. the Shafts 70, 71 now rotate in the direction of arrows 86 and 87. When the tape 60 is pulled out, that it runs along the path shown in Fig. 3, it can by a not shown, suitable Mechanism are brought into this movement track, and the rods 70, 71 are again in their Returned to the initial position in which they are not engaged with the cassette 10 and the tape 60.

In this way, the belt 60 is brought into a path, which a drive shaft 78, sound and / or Control magnetic heads 79,80, a rotatable four-head carrier with a motor 81, the head wheel 82 and a guide shoe 83, an erase head 84 and a deflection shaft 85. If the tape is 60 with Using the rods 70, in the position shown in Fig. 8, then it can with the help of a further mechanism, also not shown

ίο between the head wheel 82 and the shoe 83 in the shown tape path can be picked up. This tape path is shown only symbolically in Fig. 8, its individual parts can be adapted in their arrangement to special applications. The arrival

S5 drive mechanism 77 then drives the coils Via the transmission means 75, 76 together with the drive shaft 78, so that the belt 60 between the coils expires and a recording or playback of signals is possible in the usual way.

ao After the end of the recording or playback, the operation of the insertion mechanism explained above runs the other way around. The rods 70, 71 are operated by the mechanism 72 so that again the tape loop shown in Fig. 8 is formed by the tape 60 from its position between the head wheel 82 and shoe 83 is pulled out and also comes free of the other elements of the tape path. When the bars 70, 71 return to the cutouts 45, 46, the belt 60 is driven by the drive mechanism 77 wound back onto the spools. The tape 60 is back in the cassette 10, as shown in FIG. 6, the rods 70, 71 then slide out of the cutouts 45, 46 again out. The side parts 22, 24 can be closed around the cassette 10, and the cassette 10 can be used to Storage can be removed from the bracket, not shown.
