Abstract: In an apparatus for turning over individual sheets assembled to form a stack, preferably for leafing through program tiles of a jukebox, the sheets are arranged to pivot about mutually parallel pivot pins and are provided with projections rising above the pivot pins on which a support engages so that a sheet is turned over to the opposite side. A space-saving design, in which unintentional turning-over of the pages is effectively prevented, is provided in that at least one fixing device and stop device are provided, the fixing device being in contact with the open sheets so that in the turning-over movement of an open sheet it is moved against a force acting on the fixing apparatus, and the stop device being arranged so that the sheets adjoining the open sheets are in contact with the stop device so that their pivoting in the turning-over direction is prevented at least until the projections of the adjacent sheets are in a position of engagement with the support.

Abstract: The invention concerns a disk-changing unit comprising a tower housing (1) in which is fitted at least one interchangeable disk magazine (13), at least one disk drive (14), if necessary a disk-loading/ejecting drawer (12), a transporting device (17) for moving a disk between the disk magazine (13), the disk drive (14) and if necessary the disk-loading/ejecting drawer (12), an operating device (6) and a computer-controlled control unit (9). To be able to assemble the disk-changing unit individually with the disk magazine (13), the disk drive (14) and if necessary the disk-loading/ejecting drawer (12), the disk magazine (13), the disk drive (14) and the disk-loading/ejecting drawer (12) have the same external dimensions and are modulatively fitted next to each other by being pushed in or pulled out of corresponding recesses (10) and can thus be interchanged, replaced an/or added to.

Abstract: A transport device (10) conveys a disc holder (7) with a disc (1) between a disc magazine (4) and another disc magazine (4), between a disc magazine (4) and a running gear (5), or between a disc magazine (4) and a disc loading and issuing slide (11). Two horizontally movable extractor devices (9) on the transport device (10) travel simultaneously in opposite directions crossing each other between a ready position and a transport position. In the ready position, the extractor devices (9) are ready to engage a disc holder (7) from a disc magazine (4). In the transport position, the extractor devices (9) have traveled to their end positions on the transport device (10) and are ready to engage the disc holder (7) to transport the disc holder (7) to another disc magazine (4).

Abstract: A disc player has two opposite disc magazines with a plurality of disc holders which each receive a disc and are arranged one above the other in compartments. A transport arrangement movable in the direction of the stack of discs in the magazine conveys a desired disc with its associated disc holder between the compartment and a playback unit. The transport arrangement has a horizontally movable pulling-out arrangement provided with a carriage with a pick-up arm. In order to simplify the construction, the pick-up arm, which is rigidly linked to the carriage of the delivery arrangement, may be horizontally moved between and vertically moved within the disc magazines.

Abstract: A combination includes a plurality of disc assemblies, each having: a disc; a cassette having a window and a sliding element adapted to open and close the window, the disc being disposed in the cassette so as to be accessible by a playback unit of a disc player through the window. The combination further includes a disc player having: a playback unit; a disk magazine including a plurality of disc compartments disposed to form a stack, each of the compartments being adapted to receive a corresponding one of the disc assemblies therein; a transport device travelling toward and away from the stack for transferring a pre-selected disc assembly between a corresponding receiving compartment and the playback unit; and a plurality of cassette holders, each holding a corresponding one of the disc assemblies therein and further being adapted to be gripped by the transport device for being transferred between a receiving compartment and the playback unit.

Abstract: An automatic bowling alley has a bowling lane with two ends. The bowling alley further includes a pin setup frame provided at one end of the bowling lane for handling a plurality of bowling pins. The pin setup frame includes a pin magazine for retaining a number of the pins therebelow. A pin support plate is located below the pin magazine. A device is provided for vertically moving the pin support plate in and out of an initial position and toward and away from the pin magazine to receive the pins from the pin magazine. A device is provided for tilting the pin support plate during the vertical movement into an intermediate tilting position to clear any pins therefrom. A sorting device is located beneath the pin support plate for separating and arranging the pins received therein into an aligned position. A pin conveyor is provided for transporting, in a predetermined position, the pins from the sorting device to the pin magazine.

Abstract: A record playing device includes a record magazine that contains record holders with records located in superimposed storage compartments. A record playback unit is located adjacent the record magazine and a travelling transport device conveys a desired record with the record holder back and forth between a selected storage compartment and the playback unit. A lifting and lowering device is disposed above the playback unit and includes a vertically extending guide rod and a holding mechanism seated to glide on the guide rod. A bracket is fixed to the holding mechanism and includes a record hold-down element for receiving a record holder with a record. A motor-driven eccentric control is coupled to the holding mechanism for lowering and lifting the holding mechanism together with the bracket along the guide rod.

Abstract: A disk play-back device includes a housing having an upper and a lower wall each having a respective opening. At least one exchangeable disk magazine is provided that contains superposed disk holders and that is insertable into the housing between the upper and lower walls. The disk magazine includes a front wall having a plurality of recesses formed therein, and a bottom and a top wall each having an opening in registration with the respective openings of the housing when the magazine is inserted in the housing. A catch device is located on the front wall of the disk magazine for fixing the disk magazine in position in the housing. The catch device includes a pressure spring having two ends, and two levers. Each lever is located behind a respective recess, and each has a front end facing the other front end.
