Description

Die Erfindung bezieht sich auf eine Anzeigeeinrichtung, insbesondere zur Darbietung von Musiktiteln bei einem Musikautomaten, mit zwei in einem Rahmen-Gehäuse nebeneinander angeordneten Stapeln von vertikal und hintereinanderstehenden Informationsträgern, von denen der vordere Informationsträger des einen Stapels und der hintere Informationsträger des anderen Stapels gleichzeitig jeweils zu dem anderen Stapel hin verschiebbar sind.The invention relates to a display device, in particular for the presentation of music tracks in a music machine, with two stacks of vertical and successive information carriers arranged side by side in a frame housing, of which the front information carrier of one stack and the rear information carrier of the other stack at the same time are slidable to the other stack.

Musikautomaten bieten dem Benutzer eine große Anzahl an Musikstücken, üblicherweise in der Größenordnung von mehreren hundert einzelnen Musikkompositionen, wobei derzeit beispielsweise auf einer einzigen Kompakt-Disc-Platte bis zu zwanzig Musikkompositionen gespeichert sind. Die Auswahlmöglichkeit wird gewöhnlich in einer als Anzeigeeinrichtung ausgebildeten Programmübersicht dargeboten, aus der der Benutzer nach Einwurf eines entsprechenden Geldbetrages in den Musikautomaten eine gewünschte Wahl hinsichtlich eines oder mehrerer Musikstücke trifft, das entsprechende Kennzeichen des Musikstückes über eine Tastatur in das Wahlsystem des Musikautomaten eingibt und auf diese Weise den Spielvorgang auslöst. Für die Darbietung einer großen Auswahl von Musiktiteln ist demnach eine relativ große Sichtfläche notwendig.Music automats offer the user a large number of pieces of music, usually on the order of several hundred individual music compositions, with up to twenty music compositions currently being stored, for example, on a single compact disc disk. The selection option is usually presented in a program overview designed as a display device, from which the user makes a desired choice with regard to one or more pieces of music after inserting a corresponding amount of money into the music machine, enters the corresponding identifier of the piece of music via a keyboard into the voting system of the music machine and opens it this way triggers the game process. A relatively large viewing area is therefore necessary for the performance of a large selection of music tracks.

Aus der DE-PS 23 07 309 ist bereits eine Anzeigeeinrichtung für einen Musikautomaten mit einer Vielzahl von übereinander angeordneten, um axiale Wellenstummel drehbaren, parallelen Polygontrommeln bekannt, die jeweils mehrere im wesentlichen ebene Sichtflächen mit Halterungselementen zur Halterung einer Streifenkarte mit einer visuell lesbaren Anzeige aufweisen. Die Polygontrommeln sind mit einer Antriebseinrichtung gekoppelt, bei deren Betätigung alle Polygontrommeln gleichzeitig um einen gleichen Winkelweg gedreht werden, wobei eine andere Sichtfläche jeder Polygontrommel in Sichtstellung gedreht wird. Zur Vergrößerung des Programmangebotes können mehrere solcher Anzeigevorrichtung nebeneinander angeordnet werden. Zwar läßt sich auf diese Weise das Programmangebot erhöhen, jedoch nur bis zu einem gewissen Grade, da beispielsweise bei einem Angebot von über tausend Musiktiteln der Platzbedarf für die Polygontrommeln zu groß wird. Darüber hinaus ist der Antrieb der einzelnen Polygontrommeln relativ störanfällig, was zu einem häufigen Ausfall der Anzeigeeinrichtung führt.From DE-PS 23 07 309 a display device for a music machine with a plurality of superposed, rotatable about axial shaft ends, parallel polygonal drums is known, each having a plurality of substantially flat visible surfaces with mounting elements for mounting a strip card with a visually readable display. The polygon drums are coupled to a drive device, when actuated, all polygon drums are rotated simultaneously by the same angular path, with a different visible surface of each polygon drum being rotated into the visible position. To enlarge the range of programs, several such display devices can be arranged side by side. The range of programs can be increased in this way, but only to a certain extent, since, for example, the space required for the polygon drums becomes too large when there are over a thousand music tracks. In addition, the drive of the individual polygon drums is relatively prone to failure, which leads to frequent failure of the display device.

Weiterhin ist aus der DE-PS 20 44 028 eine Vorrichtung zum Darbieten von Musiktiteln bei einem Musikautomaten bekannt, die eine Reihe von an einem Endlosförderer hintereinander angeordneten und um eine Querachse schwenkbaren flachen Informationsträgern für beidseitige Beschriftung aufweist. Die Informationsträger sind im Umlauf innerhalb einer Führung mit inneren und äußeren Führungswänden an einem Gehäusefenster vorbeibewegbar. Zum Selbsttätigen Schwenken der Informationsträger um 180° ist eine Wendevorrichtung vorgesehen, die an einem Punkt der Umlaufbahn der Informationsträger angeordnet ist, an dem die Führung unterbrochen ist. Der Endlosförderer mit den Informationsträgern ist von Hand in nach Bedarf entgegengesetzten Umlaufrichtungen antreibbar, wobei unabhängig von der Umlaufrichtung eine Schwenkung der Informationsträger auftritt. Auch eine derartige Vorrichtung benötigt, falls sie für die Darbietung einer sehr hohen Anzahl von Musiktiteln ausgelegt ist, einen verhältnismäßig großen Einbauraum und ist darüber hinaus aufgrund ihres komplizierten Aufbaus äußerst störanfällig.Furthermore, from DE-PS 20 44 028 a device for performing music tracks in a music machine is known, which has a series of flat information carriers arranged one behind the other on a continuous conveyor and pivotable about a transverse axis for double-sided labeling. The information carriers can be moved past a housing window within a guide with inner and outer guide walls. For the automatic swiveling of the information carriers through 180 °, a turning device is provided, which is arranged at a point in the orbit of the information carriers at which the guidance is interrupted. The endless conveyor with the information carriers can be driven by hand in opposite directions of rotation, as required, the information carriers pivoting independently of the direction of rotation. Even such a device, if it is designed for the performance of a very large number of music tracks, requires a relatively large installation space and, moreover, is extremely susceptible to failure due to its complicated structure.

Ferner offenbart die DE 37 37 585 A1 eine Anzeigeeinrichtung für einen münzbetätigten Musikautomaten, die als von außen weiterschaltbares Klappkarten-Karussell ausgebildet ist, dessen Klappkarten jeweils auf der Vorderseite und der Rückseite die Musiktitel tragen, wobei die Klappkarten an einem von einem Antriebsorgan nur in einer Richtung drehbaren Klappkarten-Halter schwenkbar gelagert sind, um jeweils beim Passieren einer gehäusefesten Nase von einer Vorderseiten-Anzeigelage in eine Rückseiten-Anzeigelage umzuklappen. Zwar kann auf jeder Klapptafel eine Vielzahl von Musiktiteln dargeboten werden, jedoch erfordert das Klappkarten-Karussell insgesamt aufgrund der Rotationsbewegung der einzelnen Klappkarten um den Klappkarten-Halter einen vergleichsweise tiefen Einbauraum. Darüber hinaus unterliegen die Klappkarten beim Passieren der gehäusefesten Nase einem erhöhten Verschleiß, der zu einem Ausfall des Klappkarten-Karussells führen kann.Furthermore, DE 37 37 585 A1 discloses a display device for a coin-operated music machine, which is designed as a folding card carousel that can be switched from the outside, the folding cards of which carry the music titles on the front and the back, the folding cards on one of a drive element only in one Are pivotally mounted towards the rotatable folding card holder, in order to fold down from a front display position into a rear display position when passing through a housing-fixed nose. A large number of music tracks can be presented on each folding board, but the folding card carousel requires a comparatively deep installation space overall due to the rotation of the individual folding cards around the folding card holder. In addition, the folding cards are subject to increased wear when passing through the housing-fixed nose, which can lead to failure of the folding card carousel.

Des weiteren ist aus der W0-A-88/02532 eine Anzeigeeinrichtung mit zwei nebeneinander angeordneten Stapeln von vertikal und hintereinanderstehenden Informationsträgern bekannt, die zyklisch zwischen den beiden Stapeln ausgetauscht werden können.Furthermore, from W0-A-88/02532 a display device is known with two stacks of vertical and successive information carriers arranged side by side, which can be exchanged cyclically between the two stacks.

Der Erfindung liegt die Aufgabe zugrunde, eine Anzeigeeinrichtung der eingangs genannten Art zu schaffen, die bei kleinem Bauvolumen und einfachem Aufbau eine sehr große Anzahl von Informationen zur Anzeige bringt.The invention has for its object to provide a display device of the type mentioned that brings a very large amount of information to the display with a small volume and simple structure.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die beiden Stapel zur Verschiebung des entsprechenden vorderen und hinteren Informationsträgers um die Stärke eines Informationsträgers versetzt schrittweise synchron gegeneinander verfahrbar sind, und die Umlaufrichtung der verfahr- und verschiebbaren Informationsträger umkehrbar ist, wobei die Informationsträger eines jeden Stapels randseitig in den Gewindegängen von Gewindespindeln gelagert sind, und die Gewindespindeln des einen Stapels gegenläufig synchron zu den Gewindespindeln des anderen Stapels anteibbar sind.This object is achieved in that the two stacks to shift the corresponding front and rear information carrier by the strength of an information carrier offset step by step synchronously with each other are movable, and the direction of rotation of the movable and displaceable information carriers is reversible, the information carriers of each stack being mounted at the edges in the thread turns of threaded spindles, and the threaded spindles of one stack being counter-synchronous to the threaded spindles of the other stack.

Durch diese Maßnahmen ergibt sich neben der einfachen Verfahrbarkeit der Informationsträger-Stapel eine äußerst kompakte und damit nur einen relativ kleinen Einbauraum beanspruchende Anzeigeeinrichtung, bei der der Transport der einzelnen Informationsträger in die Blickrichtung des Betrachters praktisch innerhalb des Platzbedarfes der beiden nebeneinanderliegenden Informationsträger-Stapel erfolgt. Auf den Vorderseiten der stapelförmig angeordneten Informationsträger läßt sich eine große Menge dem Betrachter zugänglicher Informationen unterbringen. Ferner kann durch die Umkehrung der Umlaufrichtung der Informationsträger eine gerade am Betrachter vorbei bewegte Information schnell wieder in das Blickfeld des Betrachters zurückgeholt werden. Daher eignet sich die Anzeigevorrichtung besonders zum Darbieten und Auswählen von Musiktiteln eines Musikautomaten. Weiterhin ist jede beliebige Einbaulage der Anzeigeeinrichtung möglich. Darüber hinaus können mehrere Anzeigeeinrichtungen zur Vergrößerung des Informations-Angebotes ohne großen technischen Aufwand zu einer Baueinheit zusammengefaßt werden.These measures, in addition to the simple movability of the information carrier stacks, result in an extremely compact and thus only a relatively small installation space, in which the transport of the individual information carriers in the viewing direction of the viewer takes place practically within the space requirement of the two adjacent information carrier stacks. A large amount of information accessible to the viewer can be accommodated on the front sides of the information carriers arranged in a stack. Furthermore, by reversing the direction of rotation of the information carriers, information that has just moved past the viewer can be quickly brought back into the viewer's field of vision. Therefore, the display device is particularly suitable for the performance and selection of music titles of a music machine. Any installation position of the display device is also possible. In addition, several display devices can be combined to form a structural unit to enlarge the range of information without great technical effort.

Nach einer vorteilhaften Ausgestaltung der Erfindung sind jedem Informationsträger-Stapel vier Gewindespindeln zugeordnet, die paarweise gegenüberliegend in den oberen und unteren Querträgern des Rahmen-Gestells gelagert sind.According to an advantageous embodiment of the invention, four information spindles are assigned to each information carrier stack and are mounted in pairs opposite one another in the upper and lower cross members of the frame frame.

Zur Erzielung eines exakten schlupffreien Antriebes der Gewindespindeln tragen nach einer vorteilhaften Weiterbildung des Erfindungsgegenstandes die Gewindespindeln auf ihrer über die Rückwand des Rahmen-Gehäuses vorstehenden Achse drehfest ein Zahnrad, und die Zahnräder der zu einem Informationsträger-Stapel gehörenden Gewindespindel kämmen jeweils gemeinsam mit einem Groß-Zahnrad, wobei eines der beiden, miteinander in Eingriff stehenden Groß-Zahnräder über ein Getriebe mit einem drehrichtungsumschaltbaren Antriebsmotor gekoppelt ist.In order to achieve an exact slip-free drive of the threaded spindles, according to an advantageous development of the subject matter of the invention, the threaded spindles have a gear on their axis projecting beyond the rear wall of the frame housing, and the gears of the threaded spindle belonging to an information carrier stack each mesh together with a large Gear, wherein one of the two large gears, which are in engagement with one another, is coupled via a gear to a drive motor which can be switched in the direction of rotation.

Bei einer vorteilhaften, weiteren Ausgestaltung der Erfindung treibt das angetriebene Groß-Zahnrad zwei, jeweils drehfest mit einem Zahnrad verbundene Scheiben an, die randseitig in den Gabeln zugeordneter Positionierimpulse erzeugender Gabelkoppler laufen und deren Markierungseinschnitte um 180° versetzt zueinander angeordnet sind. So ergibt sich eine günstige Überwachung der versetzten und der fluchtenden Position der Informationsträger-Stapel zueinander.In an advantageous, further embodiment of the invention, the driven large gearwheel drives two disks, each rotatably connected to a gearwheel, which run on the edge side in the forks of associated positioning impulses generating fork couplers and whose marking incisions are arranged offset by 180 ° to one another. This results in a favorable monitoring of the offset and the aligned position of the information carrier stacks with respect to one another.

Damit eine sichere Übergabe der Informationsträger von dem einen Stapel zu dem anderen Stapel gewährleistet ist, sind bei einer weiteren Ausgestaltung der erfindungsgemäßen Lösung den Informationsträger-Stapeln zwei diametral gegenüberliegende Mitnehmer zugeordnet, von denen der eine in eine Mitnahmeöffnung des vorderen Informationsträgers des einen Stapels und der andere in eine Mitnahmeöffnung des hinteren Informationsträgers des anderen Stapels bei versetzter Stapel-Anordnung eingreift, und die Mitnehmer sind entlang der beiden Stapel durch eine Verschiebeeinrichtung gegenläufig synchron bewegbar.So that a secure transfer of the information carriers from one stack to the other stack is ensured, in a further embodiment of the solution according to the invention, the information carrier stacks are assigned two diametrically opposed drivers, one of which is in a driving opening of the front information carrier of the one stack and the the other engages in a driving opening of the rear information carrier of the other stack in the case of an offset stack arrangement, and the drivers can be moved synchronously in opposite directions along the two stacks by a displacement device.

Zur Realisierung einer zuverlässig arbeitenden Verschiebeeinrichtung für die beiden Mitnehmer umfaßt nach einer Weiterbildung der Erfindung die Verschiebeeinrichtung zwei im Bereich der unteren Querträger des Rahmen-Gehäuses angeordnete Riementriebe, die durch eine gemeinsame, über ein Getriebe mit einem drehrichtungsumschaltbaren Antriebsmotor gekoppelte Verbindungswelle antreibbar sind, wobei der vorderseitige Mitnehmer an dem Obertrum und der rückseitige Mitnehmer an dem Untertrum des entsprechenden Riementriebes befestigt ist.To implement a reliably operating displacement device for the two drivers, according to a development of the invention, the displacement device comprises two belt drives arranged in the region of the lower crossbeams of the frame housing, which belt drives can be driven by a common connecting shaft coupled via a gearbox with a drive motor which can be reversed in the direction of rotation, the front driver is attached to the upper run and the rear driver to the lower run of the corresponding belt drive.

Zur Überwachung der Endpositionen des vorderseitigen Mitnehmers weist dieser bevorzugt eine abgewinkelte Nase auf, die in den Endstellungen des Mitnehmer-Verschiebeweges in die Gabel entsprechend angeordneter, einen Positionsimpuls abgebender Gabelkoppler einfällt.To monitor the end positions of the driver on the front, the driver preferably has an angled nose which, in the end positions of the driver displacement path, falls into the fork of correspondingly arranged fork couplers which emit a position pulse.

Damit die dargebotenen Informationen bei einem Musikautomaten auf einfache Art und Weise ausgewechselt werden können, ist nach einer weiteren Ausgestaltung der Erfindung jeder Informationsträger auf seiner Vorderseite mit Halterungselementen für die Aufnahme eines Cover und eines Musiktitel-Informationsstreifens versehen.So that the information presented can be exchanged in a simple manner in a music machine, according to a further embodiment of the invention, each information carrier is provided on its front side with holding elements for receiving a cover and a music title information strip.

Die Anzeigeeinrichtung weist ein Rahmen-Gehäuse 1 auf, in dem auf gleicher Höhe zwei aus Informationsträgern 2 gebildete Stapel 3 nebeneinanderliegend angeordnet sind. Von jedem, aus der gleichen Anzahl an Informationsträgern 2 bestehenden Stapel 3 ist in Fig. 1 jeweils nur der vordere und der hintere Informationsträger 2 dargestellt. Die plattenförmigen Informationsträger 2 eines jeden Stapels 3 stehen vertikal hintereinander und sind mit ihrem oberen 4 und unteren Rand 5 in den Gewindegängen paarweise gegenüberliegender Gewindespindeln 6 gehaltert. Somit stützt sich jeder Informationsträger-Stapel 2 zwischen vier Gewindespindeln 6 ab, von denen jeweils zwei in den oberen Querträgern 7 und zwei in den unteren Querträgern 8 des Rahmen-Gehäuses 1 gelagert sind. Die Achsen 9 der Gewindespindeln 6 stehen über die Rückwand 10 des Rahmen-Gehäuses 1 vor und tragen hier jeweils drehfest ein relativ kleines Zahnrad 11. Jeweils die vier Zahnräder 11, die zu den Gewindespindeln 6 eines Informationsträger-Stapels 3 gehören, kämmen gemeinsam mit einen Groß-Zahnrad 12, das auf einer an der Rückwand 10 befestigten Achse 13 gelagert ist. Die beiden Groß-Zahnräder 12 kämmen miteinander, wodurch die Drehrichtung der Gewindespindeln 6 des einen Informationsträger-Stapels 3 gegenläufig zu der Drehrichtung der Gewindespindeln 6 des anderen Informationsträger-Stapels 3 ist. In der Ebene der Achsen 13 der Groß-Zahnräder 12 steht das eine Groß-Zahnrad 12 mit einem Antriebszahnrad 14 in Eingriff, das Teil eines mit einem drehrichtungsumschaltbaren Antriebsmotor 15 gekoppelten Getriebes 16 ist. Das auf einer an der Rückwand 10 befestigten Achse 17 gelagerte Antriebszahnrad 14 kämmt mit einem Zahnrad 18, das drehfest mit einem Schneckenrad 19 verbunden ist. Das Zahnrad 18 und das Schneckenrad 19 sind auf einer Achse 20 gelagert, die in einer auf der Außenseite der Seitenwand 21 angebrachten Halterung 22 aufgenommen ist. Mit dem Schneckenrad 19 steht eine mit der Welle des Antriebsmotors 15 verbundene Schnecke 23 in Verbindung. Die Schnecke 23 stützt sich an ihrem freien Ende in einem an der Halterung 22 angebrachten Lager 24 ab, während der Antriebsmotor 15 an einem von der Seitenwand 21 abgehenden Tragarm 25 befestigt ist.The display device has a frame housing 1, in which two stacks 3 formed from information carriers 2 are arranged side by side at the same height. Of each stack 3 consisting of the same number of information carriers 2, only the front and rear information carriers 2 are shown in FIG. 1. The plate-shaped information carriers 2 of each stack 3 are arranged vertically one behind the other and are held with their upper 4 and lower edge 5 in the threads of pairs of opposing threaded spindles 6. Each information carrier stack 2 is thus supported between four threaded spindles 6, two of which are each mounted in the upper cross members 7 and two in the lower cross members 8 of the frame housing 1. The axes 9 of the threaded spindles 6 protrude beyond the rear wall 10 of the frame housing 1 and each carry a relatively small gear 11 in a rotationally fixed manner. Each of the four gear wheels 11, which belong to the threaded spindles 6 of an information carrier stack 3, mesh with one another Large gear 12, which is mounted on an axis 13 attached to the rear wall 10. The two large gearwheels 12 mesh with one another, whereby the direction of rotation of the threaded spindles 6 of one information carrier stack 3 is opposite to the direction of rotation of the threaded spindles 6 of the other information carrier stack 3. In the plane of the axes 13 of the large gearwheels 12, the one large gearwheel 12 engages with a drive gearwheel 14, which is part of a gear 16 coupled to a drive motor 15 which can be switched over in the direction of rotation. The drive gear 14, which is mounted on an axle 17 fastened to the rear wall 10, meshes with a gear 18, which is connected in a rotationally fixed manner to a worm gear 19 is. The toothed wheel 18 and the worm wheel 19 are mounted on an axis 20 which is received in a holder 22 attached to the outside of the side wall 21. A worm 23 connected to the shaft of the drive motor 15 is connected to the worm wheel 19. The worm 23 is supported at its free end in a bearing 24 attached to the holder 22, while the drive motor 15 is fastened to a support arm 25 extending from the side wall 21.

In Abhängigkeit von der Beaufschlagung des Antriebsmotors 15 können die Informationsträger-Stapel 3 entweder in eine Stellung,in der die Informationsträger 2 beider Stapel 3 exakt miteinander fluchten, oder in eine Stellung, in der die Informationsträger 2 beider Stapel gegeneinander um die Stärke eines Informationsträgers 2 versetzt sind, gefahren werden. Zur Überwachung dieser beiden Stapel-Positionen dienen zwei mit einer Schalteinrichtung der Anzeigeeinrichtung verbundene Gabelkoppler 26, in deren Gabeln jeweils randseitig eine Scheibe 27 eingreift, wobei die beiden Scheiben 27 mit um 180° versetzt zueinander angeordneten Markierungseinschnitten 28 versehen sind. Jede Scheibe 27 ist drehfest mit einem Zahnrad 29 verbunden, das mit dem angetriebenen Groß-Zahnrad 12 kämmt und gemeinsam mit der Scheibe 27 auf einer an der Rückwand 10 befestigten Achse 30 gelagert ist. Die fluchtende Stapel-Anordnung wird eingenommen, um dem Betrachter eine ebene, aus den Vorderseiten 31 der vorderen Informationsträger 2 gebildeten Betrachtungsfläche bieten zu können. Jeder Informationsträger 2 besitzt auf seiner Vorderseite 31 in entsprechender Anordnung angebrachte Halterungselemente 32 für die Aufnahme eines Cover 33 und eines Musiktitel-Informationsstreifens 34, dessen Musiktiteln jeweils eine bestimmte Kennzeichnung für die Eingabe in eine Wahltastatur des Musikautomaten zugeordnet ist.Depending on the loading of the drive motor 15, the information carrier stacks 3 can either be in a position in which the information carriers 2 of both stacks 3 are exactly aligned with one another, or in a position in which the information carriers 2 of both stacks are mutually aligned by the strength of an information carrier 2 are offset, driven. To monitor these two stacking positions, two fork couplers 26 are connected to a switching device of the display device, in the forks of which a disk 27 engages on the edge side, the two disks 27 being provided with marking incisions 28 offset from one another by 180 °. Each disc 27 is rotatably connected to a gear 29 which meshes with the driven large gear 12 and is mounted together with the disc 27 on an axle 30 fastened to the rear wall 10. The aligned stack arrangement is adopted in order to be able to offer the viewer a flat viewing surface formed from the front sides 31 of the front information carriers 2. Each information carrier 2 has on its front side 31, in a corresponding arrangement, attached mounting elements 32 for receiving a cover 33 and a music title information strip 34, the music titles of which are each assigned a specific identifier for input into a selection keyboard of the music machine.

Die versetzte Stapel-Anordnung ermöglicht die gleichzeitige Verschiebung des vorderen Informationsträgers 2 des einen Stapels 3 und des hinteren Informationsträgers 2 des anderen Stapels 3 jeweils zu dem anderen Stapel hin. Zu diesem Zweck weisen sämtliche Informationsträger 2 am unteren Rand 5 mittig eine Mitnahmeöffnung 35 auf, und den Informationsträger-Stapeln 3 sind zwei diametral gegenüberliegende Mitnehmer 36, 37 zugeordnet. In der versetzten Stapel-Anordung greift der vorderseitige Mitnehmer 36 in die Mitnahmeöffnung 35 des vorderen Informationsträgers 2 des einen Stapels 3 und der rückseitige Mitnehmer 37 in die Mitnahmeöffnung 35 des hinteren Informationsträgers 2 des anderen Stapels 3 ein. Über eine Verschiebeeinrichtung 38 sind die beiden Mitnehmer 36, 37 synchron gegenläufig bewegbar, d.h. die Mitnehmer 36, 37 können gleichzeitig den vorderen Informationsträger des einen Stapels 3 und den hinteren Informationsträger 2 des anderen Stapels 3 zu dem jeweils anderen Stapel 3 hin befördern. Anschließend kann durch entsprechende Ansteuerung des Antriebsmotors 15 wieder die fluchtende Stapel-Anordnung eingenommen werden. Zur Überwachung der Endstellungen der Mitnehmer 36, 37 besitzt der vorderseitige Mitnehmer 36 eine abgewinkelte Nase 39, die in den Endpositionen des Mitnehmer-Verschiebeweges in die Gabel entsprechend angeordneter, einen Positionsimpuls an die Schalteinrichtung abgebender Gabelkoppler 40, 41 einfällt.The offset stack arrangement enables the front information carrier 2 of one stack 3 and the rear information carrier 2 of the other stack 3 to be simultaneously displaced toward the other stack. For this purpose, all information carriers 2 have a driving opening 35 in the center at the lower edge 5, and two diametrically opposed drivers 36, 37 are assigned to the information carrier stacks 3. In the offset stack arrangement, the front driver 36 engages in the driving opening 35 of the front information carrier 2 of one stack 3 and the rear driver 37 engages in the driving opening 35 of the rear information carrier 2 of the other stack 3. The two drivers 36, 37 can be moved synchronously in opposite directions via a displacement device 38, i.e. the carriers 36, 37 can simultaneously convey the front information carrier of one stack 3 and the rear information carrier 2 of the other stack 3 to the respective other stack 3. The aligned stack arrangement can then be taken up again by appropriate control of the drive motor 15. To monitor the end positions of the drivers 36, 37, the front driver 36 has an angled nose 39 which, in the end positions of the driver displacement path, falls into the fork in accordance with the fork coupler 40, 41 which emits a position pulse to the switching device.

Der vorderseitige Mitnehmer 36 ist an dem Obertrum 42 eines Riementriebes 43 und der rückseitige Mitnehmer 37 an dem Untertrum eines Riementriebes 44 befestigt. Die Umkehrrollen 45 der beiden Riementriebe 43, 44 lagern sich auf an den unteren Querträgern 8 angebrachten Achsen 46, während die Antriebsrollen 47 drehfest auf einer gemeinsamen Verbindungswelle 48 angeordnet sind. Die Verbindungswelle 48 ist in einer auf der Außenseite der Seitenwand 21 angebrachten, U-förmigen Halterung 49 gelagert. Mittig nimmt die Verbindungswelle 48 drehfest das Schneckenrad 50 eines Schnekkengetriebes 51 auf. Die mit dem Schneckenrad 50 kämmende Schnecke 52 ist mit der Welle eines drehrichtungsumschaltbaren Antriebsmotors 53 gekoppelt. Durch eine Änderung der Drehrichtung des Antriebsmotors 53 ergibt sich eine Änderung der Bewegungsrichtung der Mitnehmer 36, 37, so daß die Informationsträger 2 in Abhängigkeit von der Drehrichtung der Gewindespindeln 6 in beiden Richtungen zwischen den Stapeln 3 ausgetauscht werden können.The front driver 36 is attached to the upper run 42 of a belt drive 43 and the rear driver 37 to the lower run of a belt drive 44. The reversing rollers 45 of the two belt drives 43, 44 are supported on axles 46 attached to the lower cross members 8, while the drive rollers 47 are arranged in a rotationally fixed manner on a common connecting shaft 48. The connecting shaft 48 is mounted in a U-shaped bracket 49 attached to the outside of the side wall 21. In the middle, the connecting shaft 48 rotatably receives the worm wheel 50 of a worm gear 51. The worm 52 meshing with the worm wheel 50 is coupled to the shaft of a drive motor 53 which can be switched over in the direction of rotation. A change in the direction of rotation of the drive motor 53 results in a change in the direction of movement of the drivers 36, 37, so that the information carriers 2 can be exchanged between the stacks 3 in both directions depending on the direction of rotation of the threaded spindles 6.

Die vorstehende Zeichnungsbeschreibung hat die besonders einfache und praktisch zu handhabende Konstruktion der Anzeigeeinrichtung für einen Musikautomaten, die sich unbeschadet ihrer Einfachheit und Kompaktheit gleichwohl als äußerst zuverlässig erweist, in ihren Einzelheiten verdeutlicht.The above description of the drawing has clarified the particularly simple and practical construction of the display device for a music machine, which, despite its simplicity and compactness proves to be extremely reliable, in its details.
