• the player 10 is actuated by means of buttons 28 to 32 to turn the player 10 on and select a CD 40 from magazine 21.
• Solenoid 74 is actuated to raise cover 82.
• the playing means housing 66 is rotated via motor 48 and gears 63, 65 to rotate housing 66 until the vacuum pad 99 in arm 98 is disposed above the CD 40 selected.
• Solenoid 74 is now actuated to lower cover 82 so that pad 99 engages the top slanting surface of the CD 40 selected (see Figs. 3 and 7). Air is sucked out of pad 99 via tube 103 creating a vacuum at pad 99 holding the CD 40 to pad 99 by vacuum.
• Solenoid 74 is again actuated to pick up cover 82, with CD 40 adhering to pad 99 by vacuum, (see Fig. 10) , and pad 99 moves from the dotted line position 99' in Fig. 3 via motor 105 and gears 118, 119 and shaft 111 to the solid line position.
• This is also shown schematically in Figs. 4 and 5 wherein pad 99 is first moved from the playing area to the selected CD 40 at dotted line 99' (Fig. 4), then back to the playing area (e.g., from the solid line position 99 in Fig. 5 back to the dotted line position 99' at the playing area).
• the empty section 400 see Fig.
• the hub 70 stops rotating, the inner operating mechanism disengages hub 70 and solenoid 74 is actuated to prepare the player 10 for another cycle.
• housing 41 is merely moved up to the uppermost magazine 21' (after playing the CDs 40 in lower magazine 21, if desired) via motor 54 and screw shafts 129, 132 to play CDs 40' in the upper magazine 21'. It can be seen that there is disclosed a CD player which can accept a plurality of stacked magazines, each magazine containing a number of CDs, and select such CDs one at a time for playing the same. The player can be actuated remotely by a remote control as is well known in the electronics art.
• the jackets for the CDs may be kept in an indexed Rolodex-type container.
• the different magazines allow a large number of CDs to be stored therein, without need for touching them again, then selective magazines can be added to or removed from the player 10 to play the same. Although two such magazines are disclosed, obviously a larger number can be provided with shaft 61 elongated accordingly. Since the magazine does not rotate, the player will fit into a preexisting high fidelity system since there is no need for an extension of the player to accommodate a rotating carousel.
• the front of applicants' player herein is flush and vertical without need for a continuation of the circular housing comprising the magazine since the carousel remains stationery.
