Espresso brewing device according to claim 1, characterised by the fact that the magazine table ( 17 ) with the magazine tubes can be separated from the drawn-out magazine table drawer ( 18 ). 3. Espresso brewing device according to claim 1, characterised by the fact that the magazine tubes ( 20 ) are each provided, in a lower section of their jacket located above the magazine table ( 17 ), with a capsule magazine opening ( 33 ) radially open towards the outside and serving as a passage for the lowest-positioned single-serving capsule ( 16 ) stored with its base facing downwards inside a magazine tube ( 20 ) whereby the capsule is pushed-out through the passage via an electromotive-actuated capsule gripper ( 23 ) when the magazine tube is in the dispensing position, and by the fact that a capsule sliding path ( 41 ) extends between the magazine table and the brewing unit whereby the pushed-out single-serving capsule ( 16 ) is able to slide further towards the brewing unit via the capsule gripper ( 23 ). 4. Espresso brewing device according to claim 3, characterised by the fact that a capsule ejection slot ( 49 ) extending radially up to the outer edge of the magazine table ( 17 ) and open in that area is formed below each magazine tube ( 20 ), whereby the capsule ejection slot ( 49 ) meets a capsule gripping guide ( 22 ), formed from the capsule slide path ( 41 ) and extending up to the brewing unit, when one of the magazine tubes ( 20 ) is in the dispensing position, and by the fact that the capsule gripper ( 23 ) is guided, as part of a capsule conveying device, in a sliding manner within the capsule gripping guide ( 22 ) and the adjoining capsule ejection slot. 5. Espresso brewing device according to claim 4, characterised by the fact that the capsule gripper ( 23 ) is connected inside the capsule conveying device with a capsule conveying driving motor ( 32 ) via an actuating lever ( 24 ) and drive mechanism elements ( 31 , 37 , 38 , 40 ). 6. Espresso brewing device according to claim 1, characterised by the fact that the magazine is essentially positioned adjacent to the brewing unit and that the capsule conveying device is designed only for the horizontal conveyance of the single-serving capsules ( 16 ) and is essentially positioned between the magazine and the brewing unit. 7. Espresso brewing device according to claim 1, characterised by the fact that the magazine table ( 17 ) is in an actuation-connection with a Maltese-cross-type drive including a driving motor ( 30 ), a drive mechanism ( 29 ), a Maltese-type disc ( 27 ) with a driving pin ( 28 ) and positioned below the magazine table on the support frame, and by the fact that the driving pin ( 28 ) is in close touch with one of several Maltese-type gripping flanks ( 58 ) located at the lower surface of the magazine table ( 17 ). 8. Espresso brewing device, especially according to claim 1, characterised by the fact that the magazine table ( 17 ) is provided with a zero setting reference mark ( 47 ) able to be scanned. 9. Espresso brewing device according to claim 8, characterised by the fact that the magazine table ( 17 ) is provided wi th an electronic position recognition device consisting of a scanner of the zero setting reference mark ( 47 ) and a two-direction meter counting operational steps carried out by the Maltese-type drive in each direction of rotation starting from a zero setting of the magazine table ( 17 ), whereby the position recognition device is part of a logical control system controlling a set movement of a randomly selected magazine tube using the shortest possible path into the dispensing position. 10. Espresso brewing device, according to claim 1, characterised by the fact that the magazine table ( 17 ) is provided in the area below each magazine tube ( 20 ) with a transparent window ( 57 ) for scanning the base of a single-serving capsule ( 16 ), and by the fact that at least one sensor/scanner ( 55 , 56 ) is positioned below the magazine table ( 17 ) at the path of movement of the transparent windows able to rotate together with the magazine table ( 17 ) and is directed towards the path of movement of the respective window. 11. Espresso brewing device according to claim 1, characterised by the fact that a sensor ( 56 ) is located in the dispensing position for the purpose of monitoring the presence of a single-serving capsule ( 16 ). 12. Espresso brewing device, especially according to claim 1, characterised by the fact that a scanner ( 55 ) is positioned before the dispensing position in the direction of rotation of the magazine table ( 17 ), whereby a code concerning the coffee type applied to the base of the lowest single-serving capsule ( 16 ) inside one of the magazine tubes ( 20 ) can be scanned. 13.
