030008/0785

--er- 7/30/79

Arms 94A and 94B and a second wire spring 95 with the both arms 95A and 95B.

Finally, an electromagnet EM is attached to the rear wall 10A of the base plate 10.

The individual parts of the device are assembled as follows:

The lever 20 is pushed with the socket 24 over the pin 18 on the bottom 10C of the base plate 10 so that it is rotatable on this. The lever 20 is with the help of the coil spring 90, which is between the tongue 25 and the approach 11B is attached, biased.

The push button 70 is attached to the base plate and slides with respect to this over the lever 20; the part 71 of the key is received by the T-shaped slot 16 in the wall 10B, while the slot 76 of the tongue engages via the pin 14 of the tongue 12 on the rear wall 10A of the base plate 10. The sliding movement of the push button 70 is also passed through pin 18 which engages slot 73.

In the assembled device, the pin 78 of the push button 70 engages the curved slot 21 in the enlarged part 20A of the lever 20.

The push button 70 is biased by the coil spring 91 in the direction of arrow F1 (Figure 4); the Spring 91 acts between the circular opening 77 of the tongue 75 and the lug 16A on the front wall 10B.

The first journal bearing part 30 is movably seated on the push button 70, with the aid of the socket 34, which

Q3Q008 / 078S

7/30/79

is pushed over the pin 19 of the bottom 1OC.

When the part 30 is installed and the device itself is in the inoperative position (ejection position), the downwardly directed pin 35 of the part 30 engages into the radial groove 22 of the lever 20 and the pin 36 stands tall. The end of the arm 94A of the snap spring 94 is on the groove 27A of the pin 27 of the lever 20 anchored; the pin 27 rises above the plane of the plate 20A, while the hook-shaped end of the arm 94B the spring 94 in the slot 33 of the journal bearing part 30 intervenes.

The second journal bearing part 40 is movably arranged above the journal bearing part 30, specifically by means of the Bushing 44 which is arranged on the pin 18 above the bushing 24 of the lever 20.

The coils of the wire spring 95 "which is very strong, are placed around the body of the bushing 44 (Figure 1G), the arm 95A of the spring 95 is in singular engagement with the notch 46a on tongue 46 and arm 95B engages notch 47A on tongue 47 so that a Parallel position to the tongue 45 at a certain distance therefrom results (FIG. 1F).

In the inoperative position of the device, the end of the pin 36 of the part 30 engages in the gap between Arm 95B of wire spring 95 and tongue 45 of the part.

The "pack" of all the aforementioned components of the The device is held together by the L-shaped member 50 with the edges of the slit 55 in the groove

030008/0785

3C-.7.79

18Α of the pin 18 engage and the round opening 53 at the end of the part 50 placed over the pin 79 and through the ring 79B which is received in the groove 79A of the pin 79 is held.

The conditioning lever 60 is arranged next to the rear wall 10B of the base plate 10 and is connected to the latter Connected via the coil spring 92, on the one hand in the pierced extension 11A and on the other hand in the central circular opening 66 is anchored.

The lever 60 can rotate horizontally as a result of the pin 65 engaging the socket 13 of the tongue 12. In the position that the lever 60 assumes when the electromagnet EM is energized and the body 64 attracts and thus blocks the corresponding end of the lever 60, prevents the downwardly bent tongue 63, that the member 40 rotates clockwise because the step 48A on the curved edge 48 is engaged with it stands. The projection 62 on the lever 60 is located above the journal bearing part 40 so that the pin 43 of the part 40 can interact with him in the manner described below. The lever 60 is still like this mounted so that the magnet body 64 is located next to the pole pieces of the electromagnet EM.

The brake lever 80 is movably attached with its pierced end to the extension 11D of the wall 1OD; Consequently the lever 80 runs past the window 11E and the coil spring 93 is between the pierced The end 82 of the lever 80 and the pierced extension 11C of the rear wall 1OA of the base plate 10 of the housing are clamped.

030008/0785

In use, fully inserting the cassette C into the insertion slot causes A1 - wherein the device is in the position shown in Figure 3 - a rotation of the lever 20 in Clockwise towards the rear wall 1OA against the bias of the spring 90, which is between the approach 11B the rear wall 10A and the tongue 25 is clamped.

This clockwise rotation about pin 18 causes part 30 to turn counterclockwise rotates about the pin 19, whereby it from the position shown in Figure 3 in the position according to Figures 5 and 6 arrives. This rotation takes place because the pin 35 with the radial groove 22 on the lever 20 in the Engagement is.

Counterclockwise rotation of member 30 causes pin 36 to engage arm 95B wire spring 95 engages, causing arm 95B to rotate and tension spring 95. Farther the pin 35 emerges from the slot 22 and exerts a pressure on the outer edge 23A and tensions the Lever 20 so that it rotates clockwise until it hits the rear wall 10A under the action of the spring 95 comes to rest; the rotation takes place around the pin 36 under the action of the strongly tensioned spring.

The movements explained above are possible because the part 40 on which the spring 95 is mounted by the approach or foot 63 of the conditioning lever 60, which engages in the step 48A on part 40, on one Clockwise rotation is prevented.

030008/0785

7/30/79

Rotation of the lever 20 also turns the pen 78 of the push button 70 from the curved slot 21, in which he normally engages in the position shown in Figure 3, released.

The release of the pin 78 causes the push button 70 to move in the direction of arrow F1 under the action of from the spring 91 outgoing tension moved backwards. Meanwhile, through the introduction of the cassette C too has been achieved that the brake lever 80 rotates easily due to the engagement of the side edge BL first with the tooth 83 and then with the tooth or projection 84; this rotation takes place against the effect of the spring 93, as can be seen from FIG. The complete insertion of the cassette C also causes the start-up the usual mechanisms of a cassette recorder with which the cassette is in the operational position on the ground 1OC of the housing is brought where they are with mechanical aids that are used to move the belt, and engages with the electronic playback (and recording) aids. Such mechanical and electronic devices in cassette recorders are known to those skilled in the art and will be described in detail not further explained here. Suffice it to say that these devices are caused by the backward movement of the push button 70 can be put into operation.

The device now remains in this state until the tape is either completely unwound or until the Playback (or recording with) the cassette is interrupted for any reason. In both cases the cassette C either automatically or manually on the level of the insertion opening A1 in the front wall 1OB upscale, and in a way that isn't

030008/0785

- ti - 7/30/79

Is part of the present invention; at the same time the power supply to the electromagnet EM is interrupted. The interruption of the power supply to the electromagnet EM causes the end 64 of the conditioning lever 60 is released, which in turn causes the lever 60 due to the action of the pin 43 of the part 40 rotates counterclockwise against the notch 67.

This rotation in turn causes the projection 63 of the lever 60 to disengage from the tooth 48 of the Part 40 solves, which is so by the spring 95, which has previously been tensioned in the manner described, is forced to rotate clockwise.

The clockwise rotation of the journal bearing part 40 pulls the push button 70 in the direction of arrow F2 back, due to the engagement of the roller 42 with the inner edge of the shorter arm 52 of the L-shaped Part 50. This is possible, as already mentioned above, because das.Teil 50 with reference to pin 18 as a result of the long axial slot 55 can slide. Since the part 50 on the pin 79 of the push button 70 through the circular opening 53 is anchored, this part causes the part 70 to move together with it emotional.

It can be seen that the edge 57A of the notch 57 is designed arcuately around the pin 18, this being Shape makes it possible that the roller 42 can then detach from the notch 57.

As soon as the rotation of the part 40 is finished, the Spring 95 no longer under tension because her arms 95A

030008/0785

7/30/79

and 95B now rest against tongues 46 and 47 of part 40. Pin 36 of part 30 can as a result no longer an impact effect in the clockwise direction on the outer edge 23A of the insert and eject lever 20 exercise. As a result, the lever 20 must now under the action of the coil spring 90 opposite to Turn clockwise; the spring 90 had been tensioned when the cassette was inserted, causing the pivot bearing part 30 had rotated clockwise around the pin 27 of the lever 20 and on the edge 37 of the Part 30 acted.

The snap spring or bistable wire spring 94, the between the slot 33 of the journal bearing part 30 and the groove of the pin 27 exerts its effect, holds in this moment the pin 27 in engagement with the edge 37 of the journal bearing part 30. The pin 27 engages into the hook-shaped part 37A, whereby the rotation of both elements in the position shown in Figure 6B is stopped; in this position the cassette C has only been partially ejected from the lever 20. Consequently In this position, the cassette is only slightly out of the slot A1 in the front wall 10B of the housing emerged.

To fully eject the cassette C, it is sufficient to push the cassette C a little inwards; this movement becomes the bistable Spring 94 caused to jump to the other stable position (Figure 6C) in which the spring hits the pin 27 of the lever 20 moves away from the hook 37A, causing the lever 20 to rotate under the action of the Tension of the spring »90 can continue.

030008/0785

7/30/79

This further rotation of the lever 20 and the trunnion part 30 in turn causes the device to have its original position (Figure 3) can resume because the rotation causes the pin 78 of the push button 70 again engages in the curved slot 21 of the lever 20, which counteracts the action of the spring 91 remains in the retracted position shown in FIG. At the same time, the second journal bearing part rotates 40 counterclockwise due to the clockwise rotation of the first journal bearing part 30 and thus the pin 36, which is connected to the tongue 45 of the second part 40 in Engagement is.

The operation of the braking device comprising the brake lever 80 and the coil spring 93 is very simple. This braking device does not hinder the introduction of the cassette C, the side wall PL of the same initially steps with it the first tooth 83 and then with the second tooth 84 in engagement, causing the lever 80 to have two short successive counterclockwise rotations about the movable end 81 against the action of the tension the spring 93 executes, the lever 80 moving into the position shown in FIG.

In contrast, during the ejection of the cassette, the braking effect of the lever 80 is only negligible as long as until the cassette wall PL has come into engagement with the tooth (Figure 5), because as soon as the inner end of this wall is no longer in engagement with tooth 84 (FIG. 6), tooth 83 is under tension the spring 93 acts on this wall. This effect is very strong because of the power arm of the Spring, the distance between the tooth 83 and the

030008/0785

7/30/79

End 82 of the lever 80 corresponds.

The downward attachment of tooth 84 (Fig 1Q) prevents the lever 80 from rotating under the action of the spring 93 when the cassette C is in the operative position is lowered at the bottom 1OC of the housing.

The braking device consisting of lever 80 and spring 93 ensures that the ejection of the cassette C in any case is stopped by the lever 20, even when the snap spring or bistable wire spring 94 through Breakage or other failure. For this reason it is also possible, for example, that the spring 94 and the hook-shaped enlarged projection 37A on the part 30, which with the pin 27 on the ejector lever 20 in The latter intervenes and stops rotating, omitted in less complex cassette recorders because the braking device explained above is present.

In Figures 7, 7A and 7B, the structure and function of a second embodiment of the braking device are explained, which is also arranged on the part 1OD of the housing. In this embodiment there is the Device consisting of a lever 180 and a leaf spring 193 attached to the outer part of the wall with rivets 194 is attached. The spring 193 has a rectangular window 195 and an open end portion 196.

The lever 180 has a curved end 181, a first tooth 183 and a second upstanding tooth 184 at opposite ends 182. At the end of the tooth 183, an insert made of a material that exerts a braking effect , for example rubber, is preferably provided;

030008/0785

- Vt - 7/30/79

the lever 180 also has a through hole 185 on tooth 183. On the front part of the upwardly directed attachment of the tooth 184 is also located a downwardly and outwardly sloping surface 184A.

The lever 180 is attached to the exterior of the wall 10D so that the open end portion 196 of the spring 193 passes through the hole 185 of the lever 180 passes and the bent end 182 rests against the outer surface of the wall 1OD so that teeth 183 and 184 engage through window 10E inwardly through wall 1OD.

The operation of the braking device described above is essentially the same as that of FIG first embodiment with the only difference that in the present case the effect that the lever 180 holds in the outwardly turned position when the cassette is in the operating position on the floor 1OC, exerted by the lever portions that lower the cassette and that on the upper bevel 184A of tooth 184 are in contact.

In addition, the lever 180 exerts a stronger braking effect than the lever 80 in the first-mentioned embodiment, due to the nature of the insert 183A.

It can be seen that the two braking devices described above make use of the same principle, namely to use the same force at different points of application along a lever, thus reducing one To achieve an effect at one point of the lever and an extremely strong effect at another point of the lever.

030008/0785

When using the embodiment described above Form of the invention, the cassette is always pulled out of the cassette recorder manually, with a Tensile force must be applied, which overcomes the frictional force, soft from the tooth 83 (or 183) on the Cassette side wall is exercised.

It is clear from what has been said above that with the aid of the invention described at the outset mentioned objects can be achieved in an effective manner with a reliable device.

It is obvious that changes and modifications are possible to the device described, without leaving the scope of the invention.

For example, it is possible to omit the curved extension 62 on the lever 60, which in cooperation with the pin 43 of the journal bearing part 40 prevents the lever 60 from returning to the normal position, in which its end 64 is attracted by the electromagnet EM until the part 40 is pushed out the cassette has turned to the normal position. The same effect can be achieved by using the radial dimensions of the tooth 48A on the part 40 increased.
