So while cassettes of this general kind are to a certain extent Scope in broadcast studios for tapes played back Voice messages (or commercials) were used, ■ They are not used to any significant extent for playing music.

Rather, the Kundfunkstudios continue to use this; conventional reel tape machines, which despite the inconvenience of j operators are much less exposed to such signal errors.

: Furthermore, the one in the ys-PS 3.35o.o25 described type twisted the tape and guided around the side surface of the spool while it is pulled by the tape drive

and therefore under tension. The belt wears out very quickly; the service life of the in the tape in the cassette.

The present invention provides a method of producing an i; nd-I

to lead loose loop made of strip-shaped material past a transducer, whereby one achieves a fidelity (in a linear recording and / or playback system) that of the is comparable to that of professional reel tape machines, even if the strip material is in a magazine » that is not precisely aligned with the machine in which it is used and which is leading the tape past the converter is. Furthermore, the process causes significantly less wear on the tape in the magazine than the one to which it is attached

is directed and constructed. j

The machine 5o has two converters 51, each with a curved '

i area 52 with which signals can be sent to the j3and 2o or | can play from him; the recording and playback i circuit corresponds to that of the model 15oo and is not here; Written. there is also a belt drive shaft 53,

i which is rotatably arranged on a frame 54 of the machine 5o on one side of the transducers 51. As in the model 15oo, the band drive wave is 53 is attached to a flywheel 55 and is driven by a drive motor 56 and a friction gear 59. The frame 54 has a front plate 59 (Fig. 6, 7) with a rectangular opening 58 and a horizontal bearing plate 6o, ; which is recessed in the front plate 59. The openings 5d and the bearing plate 6o form a station 61, in which inserted a magazine 1o in a predetermined La ^ e can be, wherein the flange 19 rests on the plate 6o

909807/0929

and the transducers 51, the tape drive shaft 53, two head shields 69 and other parts of the machine protrude through the openings 3o in the surface 29. Determine the openings 3o the position of the magazine 1o in the station 61 with respect to the machine 5o so that the slot 17 in the hub 14 on the Belt drive shaft 53 opposite side of transducer 51 lies.

The machine 50 also contains a mechanism with which the one Part of the band 2o which runs over the central opening 16 of the magazine 1o when the magazine is in the station 61 1o are gripped and guided past the transducers 51 precisely can. With a mechanism this belt part 2o is pressed against the belt drive shaft 53 so that by the rotation of the Drive shaft 53 pulls the tape 2o off the roll 22 and pulls it over the first surfaces 52 of the transducer 51.

The mechanics that 2o lifted engages the band, and it passes by the transducers 51, has two guides 62 on which is disposed laterally of the bearing element for the transducers 51 and 8Ji ₄ that are fixed ", these guides 62 necked portions, which form the slots in which the tape 2o at

its edges with respect to the post 62 axially precisely aligned and therefore the transducer 51 can be guided axially to the curved surfaces 52. A mechanism is provided that with magazine 1o located in station 61 a relative

8Q9807 / 0929

movement between the guides 62, the transducers 51 and the Over the central opening 16 extending part of the .Bandes 2o between an open position (Fig. 6), in which this band part can be brought up to or removed from the guides 62 and the transducers 51, and a closed position is effected (Fig. 7) »in which the guides 62 rest against this belt part and guide it over the surfaces 52 of the transducer 51.

The guides 62 and the transducers 51 are attached to a bearing element 66 which is slidably supported between opposing rails 67 which are attached to the frame. A cylinder pin 63 is attached to a plate 64 which is pivotably fixed on the frame 54 with a pivot pin 65. A mechanism to be described later operatively moves die.Platte 64 and the bearing element 66 opposite to one another and thus the guides 62 and the transducers 51 and the pin 63 between the open division in which the guides 62, the transducers 51 and the pin 63 are in the Station 61 located magazine 1o from the opposite sides of the running over the central opening 16 tape (Fig. 6), and the closed position (Fig. 7) back and forth, in which due to the arrangement of the guides 62 and the transducer 51 of the pin 63, the slot 17 and the tape drive shaft 53 have the effect that the tape 2o is pulled out of the llagazin 1o located in the station 61 and over a winding path of movement through the guide slots on the guides 62

909807/0929

the two curved surfaces 52 of the transducer 51 (Fi ₆ '. 7) is pulled.

The mechanics with which the belt 2o is operationally attached to the drive shaft 53 is pressed on, has a soft, resilient rubber roller 68 which is rotatably mounted on the plate 64 is. The roller 68 is lifted by means of the pivoting movement of the plate 64 with respect to the tape drive shaft 53 between a Position in which the tape drive shaft 53 and the roller 68 are spaced apart (Pig. 6), so that the Central opening 16 of the magazine 1o extending part of the tape 2o-can pass between them when the magazine Io is in the station 61 is inserted or removed from it, and a working position reciprocated in the at in the station 61 dangerous magazine 1o this tape part to the tape drive shaft 53 is pressed (Fig. 7).

The mechanism that moves the guides 62, the transducers 51 and the pin 63 to and fro between the open and closed positions also moves the rubber studs 68 to and fro between their lifted-off position in the working position. This mechanism has a play lever 7o which is arranged on the frame 54 so as to be pivotable about a rod 71 and can be pressed by hand. A cam 72, which rolls on a roller on a slide 74, is attached to the lever 6o. The cam 72 is designed so that when the lever 7o is depressed, the slide 74

90980 7/0929

along the guides 75 against the bias of a spring 76 slides away from lever 7o until that end of the cam is reached, in which the roller 73 engages in a notch in the cam 72 to the lever 7o in the depressed position keep. With this movement of the slide 74, a post 77 on the plate 64, which passes through an opening 78 in the slide 74 protrudes to move with the slide 74 so that the plate 64 moves under the force of a spring 79 and at the same time brings the pin 63 from the open to the closed position and the roller in the pressure position. During this movement, an edge is laid 8o of the plate 64 adjoins a cam surface 81 on an arm 82 which is pivotably mounted on the frame 54 at the pin 83 is so that the arm 82 pivots and the eyelet 84 attached to the arm 82 along a G-profile piece 85 on the bearing element 66 pushes around the bearing element 66 carrying the guides 62 and the transducers 51 onto the pin 63 against the tension to bring a spring 86 into its closed position.

The machine 5o also has the stop and take-up levers 9o and 91, respectively, which are pivotably mounted on the rod 71. The take-up lever 91 can be pressed together with the play lever 7o in order to close the take-up circuit in the machine press which corresponds to that of the model 15oo. The stop lever 9o still operates a mechanical mechanism like that in the 15oo model (not shown) to trigger the game lever 7o, 'so that the Roller 73 releases from the notch in cam 72 and lever 7o

909807/0929

and the slide 74 is retracted by the spring 76 into the rest position can be. The plate 64 also moves back into the starting position, with the pin 63 and the roller get into the open or * lever position and the carriage 66 ^ brings the guides 62 and the transducers 51 into their open position under the action of the spring 86.

While the machine 5o is a suitable embodiment of a Machine which can be used together with the magazine shown in FIGS. 1 to 3, can be provided by other embodiments without the basic idea of the present invention to leave. For example, a different number of converters can be provided in order to do justice to the application of the machine will. The bearing element to which the guides are attached can be fixed or part of the frame, so that you can Magazine must move back and forth between different positions in the station in order to accommodate the tape and the guides and the transducers to move back and forth between their open and closed positions. Alternatively, both the bearing element and the Magazine to be stationary in the station, while a variety of elements such as. The pen from one of the transducers and the open position at a distance from the guide, in which the

opening 16 of the magazine 1o running tape section between them can be introduced, and is movable to a closed position in which the tape is pressed against the guides and transducers will. Furthermore, the magazine and the machine construction,
