In the course of time it has become common several pieces of information that are not necessarily related attach on a common recording medium to record. A newer, typical one, but by no means The only example of this is a pre-recorded ■ magnetic tape on which a multitude of information units, for example individual pieces of music are recorded. .These pre-recorded Tapes are generally very popular, but often have the noticeable disadvantage that the The choice of pieces of music made by the manufacturer of the fire or the like does not always meet the needs of the listener is equivalent to.

In order to overcome this disadvantage, preselection devices of the type used for records could be used used, with the help of which the listener could select certain pieces to play. Well-known institutions of this kind the listener could probably hear save unwanted pieces, but require laborious and repeated operation to operate Actions by the listener. A suitable embodiment of such a playback device according to the current one Prior art may include, for example, one of Hp.nd operable push-button selector or a dial for preselecting certain pieces intended for playback before each playback process. Such Adaptable preselecting devices are very useful for those cases in which the usual one Audience includes a large number of people, most of whom choose certain pieces themselves want.

In recent years there have been in the making of taped performances as well made great strides in the creation of economical tape recorders for personal use. Pre-recorded in a private collection of tapes or self-recorded compilations of individual performances forms a very good adaptable preselector, however, is more of a burden than a relief. ' In such case it changes the individual listener namely the selection or compilation of the performances or the Performances to be excluded from playback are seldom. Under these circumstances, manual operation becomes the selection devices before each playback of the tape only to re-program a selection made long ago, i.e. an annoying task which considerably increases the pleasure of playing impaired.

On the other hand, it often happens that an individual has some piece which he in himself appreciates, but for some reason does not want to play at a given time would like to. In this case, it would be desirable to be able to change the program preselection quickly.

Similar problems also arise in connection with prerecorded magnetic image recordings or motion picture films when multiple performances are recorded on one tape or film.

The tape cassette shown in Figs. 1, 3 and 4- has a pair of halves 13 and 14 that are fitted together formed housing 12. The housing 12 contains a supply 16 of a magnetic tape 17, which from a Bnnd supply holder 18 on a tape take-up part 19 can be rewound.

On the tape 17 are a number of information units, for example musical performances 22, 23, 24 and 25, recorded (Fig. 2). Furthermore are on tape 1? a number of control signals 27, 28, 29, 30, 31 recorded. Depending on the particular use These control signals can, for example, indicate the beginning or the end of the individual performances or be used in another way for the selection of the performances.

In practical application, performances are preferably recorded on at least two recording tracks or on two stereo double tracks of the tape 17 in order to enable the information to be played back in both running directions of the tape. Each of these recording tracks is then provided with its own control signals, which are recorded on a separate control track. If necessary, the control signals can also be recorded on one or more tracks containing the performances and arranged or coded in a conventional manner in such a way that they do not inadmissibly interfere with the reproduction of recorded performances. For the sake of clarity, only one recording track 34 is assigned with oilier in FIG. Track '-'3 for tax: 13ηοIo shown.

The marking carrier 37 contains 3..b adjustment marks slidable in slots 45 in housing half I3 or control notches 40, -4-1, 42, 43. The setting mark 40 is assigned to the presentation 22, the mark 41 to the presentation 23, the mark 42 to the presentation 24 and the setting mark 43 of performance 25 (i'ig. 2).

The setting or control marks 40 to 43 are between one first position in which the reproduction of the relevant Mar'ke assigned performance is set, and a second Movable position in which the omission of the presentation assigned to the mark in question is set. In the example shown, the setting marks 40, 41 and 43 are in the first position. So you show that the Performances 22, 23 and 25 are to be played. In contrast, the mark 42 is in the second position, so that the Darbietting 24 is passed over and excluded from playback.

The performances recorded on the recording s track ^y J \ - can be played back by means of a playback head 52, while a playback head 55 is provided for scanning the control signals on the track 55 (FIG. 2). The two playback and playback heads are in I ¹ Ig. 1 are provided with the same reference numerals.

A switch 55 is used to selectively connect the playback head 52 with a playback amplifier, 55, which has a loudspeaker 57 for an audio reproduction of the performances being played feeds. A tape drive 60 is on the one hand with a drive roller 61 and on the other hand with the tape take-up reel 19 connected. When fed via an input 65, the drive 60 conveys the tape 17 via the drive roller 61 with playback or Playback speeds. When fed via an input 65, the drive 60, on the other hand, is via the take-up reel 19 effective and causes the. Volume I7.

A coupling 66 running from the drive 60 to the switch 55 provides means for closing the switch during tape transport at playback speed and opening it of the switch when fast forwarding. In this way, those moving at playback speed while the tape is being transported will be grounded Performances played while the performances passing while fast-forwarding were skipped and make no noise in the loudspeaker either.

For scanning the arm support 37 and 38 and for the corresponding Control of playback operations are as follows Control devices described with reference to FIG. 1 are advantageous usable. These devices have logical circuits according to the applied Boolean algebra. Such circuits or circuit blocks in the field of cybernetics and automated data processing. In the example shown, two AND circuits 70 and 7 ^ are one NO circuit 72 and a delay element 73 are present.

The AND circuit 70 generates a signal at the output 75 only when both inputs 76 » 77 carry voltage. In the same way, the AND circuit 7 ^ only generates a signal at the output 79 »when both inputs 80 and 81 are live. The NO circuit 72 emits an output signal at the output 83 as long as its input 84 is de-energized and does not generate a signal at the output 83 as long as the input 84 carries voltage.

The delay element 73 only emits a signal at the output 86 if at its input 87 during a certain period of time there is tension. This period corresponds to that by a search circuit 89 for finding a playback command required time span.

In the embodiment of Fig. 1, the playback commands are through the position of the setting marks 40 to 43 triggered. To this For the purpose, the search circuit 89 has a scanning device 90, which emits a signal at output 9 ^ when the sensing element 92 one of the setting marks 40 to 43 in the previously explained first position felt.

BATH ORIGINAL

108820/2121

The search circuit 89 also contains an actuating element 9 which when signals are fed in via input 96 the "Sensing element 92 advances.

Based on Fi ^. 1 and. 2 , the mode of operation of the device can be reduced. 1 as follows. At the beginning of the Abspie lens of a tape, the playback head 55 scans the control signal 27 and feeds it via a suitable playback amplifier 98 to the input 77 of the AND circuit 70, the input 87 of the delay element 75 and the input 96 of the actuator 9 '+. The actuating member 94 then switches the sensing element 92 into the position 100 in which it senses the setting mark 40 in the first position. The scanning device 90 now outputs a signal to the input 76 of the AND circuit 70.

Up to this point in time, the AND circuit did not generate an output signal, since it was only fed via input 77. Because both inputs 76 and 77 are now carrying voltage, the AND circuit 70 generates an output signal which is fed to the input 65 of the tape drive 60 so that it drives the tape at playback speed.

As explained above, the power supply via input 65 causes the tape to be fast forwarded and must be prevented in this operating state a wrong actuation of the drive 60 to be excluded.

109820/2121 BAD OWGLAL

This is done by having the output signal cn al of the UJiD circuit 70 not only dem in the manner described above Input 63 of the drive 60, but also to the input 84 of the NO circuit 72. This causes the output signal to go out the ITEIR circuit 72 at the input of the AND circuit 71, so that it is not able to emit a signal at its output 79.

Before the input 80 of the AND circuit 7 "" is de-energized, the delay element 73 prevents the supply of the sampled control signal to the input 81 of the AND circuit 71. To this end, the equivalent of the delay element 73 caused delay, as explained above, that of the search circuit 89 to find a play command required time span.

When the drive 60 is switched on for operation at playback speed, the switch 55 is closed via the coupling element 66, so that the performance 22 is reproduced via the loudspeaker 57. The control signal 27 ends after a certain time. However, since the drive 60 forms a bistable device, it remains switched on even after the signal at the input 63 has ceased.

After the performance 22 has been played back, the control signal is picked up by the head 53. Among those listed above Operating conditions, this causes the sensing element 92 to move into the position 101.

109820/2121

Since the setting mark 41 is also in the first position, the scanning device 90 and the logic circuits 70 to 75 in turn cause a signal to be fed to the input 63 and a signal at the input 65 of the drive 60 to be suppressed Presentation -22 still with Abspicülgescl .- .. vrLndigkeit running tape drive 60 now remains in this operating state, so that the presentation 23 is reproduced.

With regard to the performance 24, however, a different state occurs, since the position of the setting mark 42 in the second position indicates that the performance 24 is to be skipped. The following happens in detail. The playback head 53 scans the control signal 29, whereupon the actuating member 94 advances the sensing element 92 into the position 102. Because the setting mark 42 is in the second position, the scanning device 90 now does not generate an output signal, so that 4-way input 76 of the AND circuit 70 remains de-energized. As a result, the AND circuit 70 is unable to deliver a signal to the input 63 of the drive 60. On the other hand, the input 80 of the UIiD circuit 7 ^ now carries voltage, since the NO circuit 72 does not receive a signal at the input 84 which would block the output of a signal at the output 83.

Accordingly, after the delay given to the scanned control signal by the delay element 73 has elapsed, voltage occurs at both inputs 80, 81 of the AND circuit 71, so that the latter feeds a signal to the input 65 of the tape drive 60. This causes the Sehnellvorlauf of the tape 17 and the opening of the switch 55 by the drive 60. The performance 2Ά ] Uuft .therefore very r.

However, since the mark 43 is in the first position, this is repeated with respect to the marks 40 and 41 described process when sensing the control signal 30, so that the tape with playback speed is running and the performance 25 is being played.

At the end of the last performance, a further control signal 31 is provided, which is fed to the actuator 94, so that this the sensing element 92 in preparation for the next Playback process switches back to the starting position. The tape 17 can then be played in the opposite direction if it contains records in both directions. Otherwise, the control signal 3 ^ to initiate the Tape return in preparation for the selective playback of the presentations 22 to 25 according to the position of the setting marks 40 to 43 are used.

In practical operation, it sometimes happens that the user of the playback device sees a performance, which by the position of the corresponding setting mark on the marker carrier per se as to be played is specified, wants to skip. When a ' If the user intends to do this for a long time, he will of course be the appropriate setting mark put in the second position so that the piece in question is always left out. If such an intention but only exists temporarily or only once, it would be beneficial for the user to via a device for bypassing the area code or combination indicated by the marker carrier to grout, instead of surrounding and to be reset later. The same is true if the user plays a Performance decides to skip the rest of the performance this time.

In the device according to FIG. 1, a device for disabling the function is for this purpose Control provided with a push button switch and an electrical voltage source 203 · The switch 202 has a pair of contacts 205 and 206.

In addition, the voltage source 205 is so designed that when the "button" 08 is pressed to close the work contact 206, a voltage sufficient to switch from playback speed to fast forward is applied to input 65 of drive 60.

The selection and dimensioning of the voltage source 205 is, moreover, a matter of experience, since that for excitation the "AND circuit 70 and the drive 60 easily determine the required voltages and powers are.

If the marks are in the positions shown, the contacts or contact pairs 110, 111 and 113 are closed and the contact pair 112 are open.

A step or selector switch 115 is functionally equivalent to the actuator 94 in FIG. 1. The selector switch 11p has a number of contacts 117 to 122 _? to which a contact finger 123 can be pressed one after the other when a stepping motor 125 is switched on repeatedly. To transmit the switching movement of armature 128 of motor 125, a ratchet arrangement 127 in conjunction with a ratchet wheel 129 is provided.

The contact finger 123 is initially on a dummy contact 117. A motor 132 of the belt drive 60 is actuated an on and off switch 134 is set in motion. The drive transmission from motor I32 to the belt drive roller 61 takes place via a cord pulley 135 and a flywheel 136; Thus the tape I7 runs in the direction of the arrow I38 with playback speed.

As already mentioned, the drive 60 is bistable. That means, that the Schnurschoibenlagerung 140 depending on whether the last preceding tape transport at playback speed or in the optionally adjustable fast forward, either in the one shown with a solid line Location or in the position shown in dashed lines 141 may be ..

In both cases, the first control signal 27 is now detected by the playback head 53 (FIG. 2). After reinforcement in the amplifier 98 causes the signal to energize relays 147,148, 149 and the actuation of the stepping motor 125 of the selector switch 115. When relays 147, 148 close their contacts I50 and 151.

The closing of contact I50 remains without at this point in time Effect, since an open contact 153 of a relay 154 with him is connected in series. It can be seen that the relays 147 and 154 with their contacts I50 and 153 as elements of the Boolean, logic circuits of the AND circuit 70 in FIG. 1 correspond in terms of their effect.

The closing of the contact 15I remains in the described state likewise ineffective, until the contact finger 123 comes to rest in the manner described below comes at contact 122.

However, actuation of motor «125" causes the Contact finger 125 from Eontatet 117 hem contact 118. Since the Contact 110 is closed because the setting mark 40 is in the first position, the following stream is now * - Circle formed for the heater 154: Battery 156 - sensing contact 110 - selector!: Oiitakt 118 - contact finger 125 - relay 154 - battery 156.

With reference to the actuating element 161, it is to be stated that a stroke of this element and the actuating element 15B for open tape transport when the playback is at high speed are mutually exclusive. This finding appears to be doubtful in view of the fact that the relay 149 is immediately excited when the control signal 27 is felt and that this relay has a contact 165 which is in series with the break contact 164 of a relay 165 which is connected in parallel with the actuating element 158 and itself can only be excited when it is actuated in the manner described above.

However, it should be noted that the relay 149 is a Has delay device 167, by means of which the closing of the contact 165 when the relay 149 is energized is delayable. In the embodiment according to FIG. 5, the ... delay device 167 contains a damping cylinder 168 with a piston 169 and a return spring I70.

When energized, the relay 149 pushes the piston 169 into the damping cylinder 168. The movement of the piston that occurs 169 is held by the spring 170 and the cylinder 168 contained Air braked. These two forces can be overcome by the relay 149. Because the trapped air However, only through a narrow opening 172 from the cylinder 168 can escape, it takes a certain time for the relay 149 to move the piston 169 far enough into the cylinder 168 has pushed to close the contact 165 coupled to the piston.

The opening Λ ' is dimensioned or adjustable in such a way that the delay brought about by the device 167 corresponds to the period of time which the selector switch II5 and the switching devices connected to it require to feel the position of a specific setting mark 40 to 43. If the rake in question is in the first position, the actuating element I58 is excited in the manner explained above. At the same time, the relay 165 is energized so that its normally closed contact 164 opens. Since the latter is now open, the closing of the contact 163 has no effect after the delay caused by the device 167 has elapsed. If, on the other hand, there had been no excitation of the actuating element 158, the contact 164 would still be closed when the contact 163 was closed, so that instead of the actuating element 158, the element 161 would be excited for the fast-forwarding of the tape. From the above it follows that the relay 165 ^m it the contact 164 of the NO circuit 72 in Pig. 1 corresponds in terms of effect. On the other hand, the relay 149 with the contact 163 and the delay device 167 fulfill the punctures of the delay element 73

If the setting mark 40 is in the first position shown, the actuating element 158 is excited and the tape 17 is then transported at playback speed, so that the performance 22 over the arrangement 52,56 and 57 is played (Fig. 1,2).

Through this creates the following circuit for the actuator 161 for fast tape feed: battery 159 - contact 164 - contact 163 - Actuator 161 - Battery 159

The excitation of the actuating element 161 causes the pivoting the cord disc storage 14-0 in the position 14-1 shown in dashed lines and thus the fast tape feed. Therefore, the presentation 24- is omitted or skipped, since the drive 60 presses the switch 55 during fast forward holds open (Fig. 1,2).

Then the reproducing head 53 takes the control signal 30, whereupon the contact finger 123 is advanced to the contact 121 and thus the position of the setting mark 4-3 scans.

Since this setting mark is in the first position ", is now the actuator 158 for the tape transport Playback speed as in the case of the two marks 40, 41, which are also in the first position and the performance 25 is played.

After this performance has been played back, the control signal reaches 25 5Ί the head 53 · This causes the contact finger to be indexed 123 to contact 122, so that the following circuit for a feedback relay 180 is formed: battery 156 relay 154 - contact finger 123 - contact 122 - relay contact 151 - feedback relay 180 - battery 156.

Because the relay 154 is in series with the feedback relay 180, its contact 153 closes, which is connected in series with the contact I50 which is already closed due to the presence of the control signal y \ at the head 53. The actuating element 158 is energized and the tape is braked to playback speed. If, however, the setting mark 43 is in the first position shown, the tape 17 is of course already playing speed as soon as the control signal 31 arrives at the playback head 53. If, on the other hand, the setting mark 43 were in the second position, then the belt 17 would have cutting forward speed at that moment, with the presentation 25 being skipped. In this case, the braking of the belt 17 by energizing the actuating element 158 has a beneficial effect insofar as it alleviates the hard jerk when the ore reaches the end of the belt.

The operation of the control bypass devices έΟΛ in FIG. 5 is described below. It is assumed that the user wants to skip the second presentation 23, although the corresponding setting mark 41 is in its first position and there-

with indicates that the second display will be played target.

If the user wants to skip the second performance entirely, he presses button 208 as soon as the first performance has ended. If then the control signal 28 the stepping of the contact finger 123 triggers to contact 119 takes place despite the closing of the Eelais contacts I50 »153 3yes Period of time no excitation of the playback actuation element 158 through the battery 159 · The non-excitability of the actuating element 158 is based on the fact that the Contact 205 is open when button 208 is depressed.

The depression of the switch button 208 does not only cause the contact 205i to open but also the closing of the contact 206 and thus the initiation of the fast tape feed. In detail When contact 206 closes, the following circuit is created for fast-forward actuator 161: Battery 159 - contact 206 - actuator 161 battery 159.

Accordingly, the bistable belt drive 60 reaches its second stable position 141, which is indicated by dashed-i lines ^ cL ^ vichr.ot int, co that öp.b Bmd 1 • y

If the button 208 is then released, the belt runs thanks to the bistable belt drive 60 continues in the chord forerun at least up to following performance. In the examples shown, the third performance is skipped 24 · set so that the tape continues to fast forward until the control signal $ 0 for the fourth performance is reached. The fourth performance is then played back as described, unless the listener releases the fast-forward tape again by pressing the button 208 again the end.

The bypass device 201 is also suitable for canceling the playing of a performance and although during playback. In this case, depressing the switch button 208 causes the contact 206 closes, whereby the actuator 161 is energized. This therefore triggers the fast forward of the Tape 17 off and playback of the performance in question is interrupted.

Upon depression of the switch button 208 after the waste of the control signal for the respective performance of the reproducing head 53, the switch contact 205 does not trigger any action. In this case, a play command to the capstan 60 need au not be suppressed because the Relaisko.ntnkt 150 including Verschv / in the iJteuersignals from Wiedercntokopf ^l) 'j open Iint.

Are the individual recorded on the tape 17 Control signals relatively short, is also in general. mean just a short depression of the switch button 208 is required because the immediate fast forward the control signal quickly via the playback head 53 pulls out.

However, certain difficulties could arise if the control signals were each via a occur for a longer period of time. There is then the possibility that the control signal when releasing the Switch button 208 is still present and triggers another playback of the performance in question.

In a particular embodiment of the invention, this problem is solved in that the control bypass contains self-holding devices. An advantageous embodiment of a control bypass 200 modified in this way is shown in FIG. 4. Again, the same reference numerals in FIGS. 1, 3 and 4 denote the same or functionally similar parts, the above description with reference to FIG. 5 being used for a detailed understanding of the common parts and circuits in the device according to FIG.

The control bypass device 500 in Fig. 4 includes a manually operated switch 302 with Switch contact 206, load spring 207, and switch button 208 as noted above. Again "burdens the Spring 207 the contact 206 in the open position, and

the closing of the contact 206 can be brought about by depressing the switch button 208. The Buhe switch contact 205 is in Pig. 4 through a rest relay contact 305 replaced, the one with relay contacts 150 and 153 in Row lies. Therefore, the activation of the actuating element 15s for playback is not possible as long as like the contact $ 05 is open. Incidentally, the Energizing the play actuator 158 when the Contact 305 in the same way as described above controlled by relay contacts I50, 153.

The bypass device 300 also includes two relays 307 and 308. The heater 307 has the above listed normally closed contact 305 as well as two normally open contacts 310, 311 When the Beiais 308 is excited closes a normally open contact 312

By pressing the button 3O8 results the following circuit for the Beiais 307 * battery 159 - wire 313 - switch contact 206 relay 307 - conductor 315 - battery 159.

When the relay 307 is energized, the normally closed contact opens 305 »so that the play actuator becomes de-energized or can no longer be excited via the contacts 150, 153 connected in series.

So does the depression of the switch button 308 the fast forward of the tape 17 with abort of playing the relevant performance., The contrary Settings at the marking. girders 37 »38 are thereby deactivated. There the tape drive 60 is a bistable device, the fast forward of the tape 17 continues until a Counter-order comes.

In general, such a counter-command occurs when the selector switch 115 switches to the next Mark carrier of a cassette scanned as a performance indicated to be played. As mentioned briefly, however, an erroneous counter-command could result from the fact that the button 208 of the switch 202 (Fig. 3) as long as the relevant control signal on the tape 17 is still present at the head 55 is what is the case, for example, with correspondingly long control signals.

In the gate direction of FIG. 4, each the control signals 27, 28, 29 etc. (Fig. 2) the excitation not only dös stepping motor 125 and the relay 147 "148" but also of relay 308 in the bypass 300. As long as relay contact 311 is open, remains the energization of relay 308 has no effect. However, if relay 307 is energized in addition to relay 308, Relay contacts 311 and 312 set the following Holding circuit for relay 307: Battery 159 - conductor 313 - conductor 319 - relay contact 311 - conductor 320 relay contact 312 - wire 321 - relay 307 - wire 315 - battery 159.

In this way the relay 307 is kept energized, as long as the control signal in question is present at the playback head 53, even if the Schaltv button 208 is now released. But as soon as the control signal for the performance in question on the playback head has passed, the relay 508 falls and the relay contact 312 opens. So that is Ilaltekreis of the relay 307 interrupted, so that too this falls off. Because of the bistable design of the drive 60, the tape cutting advance continues, until the selector switch 115 is the next one on the marker carrier felt as the performance specified to be played.

From the above description, it can be seen that the control bypasses 300 according to FIG. 4 · both momentarily triggerable bypass devices with a push button switch to trigger the tape fast forward and to interrupt playing a performance as well as holding devices with the relay 308 and the relay contacts 311) 312 to continue the tendon 11 advance of the tape 17 and to interrupt playback of the relevant performance until the end of that performance in relation to which the bypassing was triggered. The continuation of the fast forward of the respective performance can be effected, without the holding device of the Steuorungsumpehung during the entire SchnellVorlaufs concerned Performance is effective. As already explained, the relay contact 312 opens and the relay 307 drops out as soon as the control signal from the playback head 53 vernchv / indet.

The tape fast forward then continues due to the "bistable design of the belt drive 60 nonetheless continued, ', ■. '

One recognizes that instead of the one in Pig. 3 and 4 also include pestbody circuits can be used with the corresponding functions.

In addition, the control bypass is not an indispensable part of the device according to the invention. the The device can therefore also be designed in such a way that it does not have the option of skipping out of the program plays all set presentations. In this case, in the device according to FIG the input 200 of the AND circuit 70, the voltage source 203 and the switch 202 are omitted. if no bypass devices are required for the device according to FIG. 3, the switch 202 is omitted and the moving part of the relay contact 153 becomes direct connected to battery 159 rather than through switch contact 205. However, the invention relates to that described Bypassing devices preferably one.

The cassette 10 shown in FIGS. 1 and 3 is as early as possible with the setting marks during manufacture 40 to 43 provided. On the other hand, cassettes without marking media or program memory are made or have marker carriers that with a given scanning and control device are not usable, are subsequently provided with such May'kiorurigfjträgern or dial memories.

For example, a marking carrier 37 of the type shown in FIGS. 1 and 3 can be used a carrier part be formed which has a cavity for receiving an edge piece of the cassette. The memory again contains setting marks, which can be moved in slots between first and second positions in order to set a preselection or combination of performances to be played back. On the underside of the part carrying the memory 37 can be another memory 38 in Pig. 3 shown Kind of be arranged to play a preselected compilation of tracks in both directions of the tape to allow. Such a carrier part can be pushed onto a handpiece of the cassette, v / o it is then held in a press fit ..

Another embodiment of the marker carrier or program spexcher contains a means Adhesive metal foil covered by a paper adhesive strip · The paper adhesive strip then has pre-perforated Tear-offs which in terms of their effect correspond to the setting marks 40 to 4-3 of the memory 37. the adhesive metal foil is attached to a cassette together with the pre-perforated adhesive tape, and the tears corresponding to the performances to be played are released from the adhesive tape. For example, if the paper strip on the metal foil has four breaks in a row, the first, Select the second and fourth performance to play and the third performance to skip by pressing the first, second and fourth tear-offs removed, but the third one left, so that in the places where ground the tears away, leaving the metal foil exposed.

Such a marking carrier or program memory with metal foil can be made by means of devices according to Fig. 3 or 4- are scanned in etv / as modified form. For this purpose, the contact arrangement 110 to 113 removed and the negative pole of the battery with the aforementioned metal foil of the Memory connected. Instead of contacts 110 to 113, electrical sensor contacts are then provided, which are connected to the dial contacts 118 to 121 in the same way as the remote contacts. To the In places where a pre-perforated tear-off has been removed, the sensor contact comes into contact with the metal foil, so that the presentation assigned to the cut-off is played when the contact finger 123 at. reaches the corresponding dial-up contact. On the other hand, there is no electrically conductive connection between the places where the tear-off was left the sensor contact and the metal foil. Corresponding to that explained above with reference to FIG In operating mode, the performance assigned to the latter outline is then not played, but in Skipped fast forward.

From the above it can be seen that the for the elements of the marker carrier or program memory The expression "setting marks" used is to be understood in the broadest sense.

In cases where it is difficult to apply control signals to the belt 17, a circuit responsive to the absence of signals can be used, in which case a recording and sampling of the control signals 27 to 31 is unnecessary will. For example, a circuit responsive to the absence of signals includes a preamplifier for amplifying the signals picked up by the playback head 52). At this, preamplifier can then the aforementioned amplifier 56 and the Speakers 57 for the playback of the played Connect performances.

A typical circuit responsive to the absence of signals also includes an integrator, which is connected to the preamplifier, integrates the played signals and has an output • signal generated as long as a performance is playing. The output signal is, for example, to an electrical Circuit laid out as a logical NO circuit operates and as does NO circuit 72 in FIG. 1 "Generates an output signal in the absence of an input signal and interrupts this when an input signal occurs.

Accordingly, the NO circuit of the circuit which responds to the absence of signals does not generate an output signal as long as the integrator is outputting an output signal. If, however, there is no recording at the playback head 52, the integrator no longer receives an input signal and its output signal drops to zero.

The amplifier 98 for energizing the relays always receives a signal when in front of or behind Performances recorded on your tape 17 will not be added up Routes occur.

As a further alternative to the control signals 27 "to 31 recorded on the tape, markings, for example in the form of electrically conductive strips, in addition to the program memories or marking carriers 37 »38 arranged on the cassette be. The additional markings can be arranged and designed in such a way that they mark the beginning and / or indicate the end or length of each recorded performance. By scanning the additional Markings it is therefore possible to use electrical signals to excite the relays 125, 14-7, 148, 149 egg devices according to FIGS. 3 and 4 for each right time to get it. A scanning device that can be used for this purpose is, for example, a spindle feed on.

In addition, FIG. 5 shows a further embodiment of the invention, the reference numerals being the same those in Figs. 1, 3 and 4 denote the same parts. In This embodiment is made of adhesive metal plates 401, 402, 403 a program or preselection memory 405 is formed on the cassette 10.

Pieces. To set a different selection of pieces, the adhesive platelets 401, and remove 405 from the cassette and reassemble in a different arrangement.

The arrangement of the platelets in the transverse direction corresponds to the length of the performances to which they are assigned. For example, the mutual spacing of the plates 401, 402 and 403 means that the first performance has a length ä, the second performance ψ length b and the third a length c, where a + b + c is the total length of the three pieces.

The tokens are arranged to indicate whether a particular performance is being played should or not. For example, a plate in the position of plates 401 and 403 indicates that the assigned track is to be played. In contrast, a indicates that the plate 402 is in the position that is to skip the performance in question is.

The scanner 408 is arranged on a threaded spindle 430 which, by means of the belt drive 60 is drivable in a first direction from the plate 401 to the plate 403 and beyond this. A first gear 431 is available for this purpose, which is used to drive a second gear 432, as long as the tape drive 60 transports the tape 17 either at playback speed or in fast forward. The first and second transmissions 431 and drive the spindle 430 so that the scanner 408 analogous to the passage of the belt 17 and a limit switch 440 simultaneously with the completion of the belt run achieved.

First, the plate 401 establishes a connection between the fingers 409 and 412, so that the Input 63 of the belt drive is supplied with voltage from a battery 441 via a break relay contact 442 will. This means that the tape is transported at playback speed, and the track assigned to the chip 401 is played.
