Claims

1. Device for turning individual sheets of multi-leaf works, in particular bound or stapled sheet music, with a support means which preferably supports the work in the open state, with a reversible electric motor, the output shaft of which is rotatably fixed between a rest position and a reversal point. and movable pendulum arm is connected, and with a movable with the pendulum arm, during the pendulum movement against the surface of the sheet to be turned and spaced from this friction roller, characterized in that the friction roller ( 14 ) from the longitudinal axis (L) of the pendulum arm ( 12 ) via a swivel arm ( 13 ; 13 A, 13 B) spaced apart, which impacts the friction roller ( 14 ) at least on a portion of the pendulum movement (A) of the pendulum arm ( 12 ) with a superimposed swivel movement which strikes the friction roller ( 14 zoom leads) to the surface of the sheet to zublätternden (1 A) and to the order scroll a single sheet ( 1 A) accelerated relative to the pendulum movement of the pendulum arm ( 12 ).

2. Apparatus according to claim 1, characterized in that by the superimposed pivoting movement of the first contact of the friction roller ( 14 ) with the surface of the sheets in the lower corner region ( 1 '; 1 ") of the sheet to be turned ( 1 A) at a distance from the lower and lateral leaf margin.

3. Apparatus according to claim 1 or 2, characterized in that the level of the pendulum movement of the pendulum arm ( 12 ) obliquely to the sheet plane, preferably at an angle of about 3-7 °, and the two planes at the lower and side edges ( 1st '; 1 ") of the switch leafing blade (1 A) have the smallest spacing from one another.

4. Device according to one of claims 1 to 3, characterized in that the rest position of the pendulum arm ( 12 ) is outside, preferably below the factory and / or the support means is a music stand ( 2 ) and / or the electric motor ( 9 ) is fixedly mounted on the support means or on a housing ( 5 ) attached to the support means.

5. Device according to one of claims 1 to 4, characterized in that on the pendulum arm ( 12 ) a second schwenkba rer, at the free end with a hold-down roller ( 16 ) ver holding arm ( 17 ) is arranged, which during the pen del movement ( A) of the pendulum arm ( 12 ) is first pivotable opposite to the pivot arm ( 13 ) of the friction roller ( 14 ) and then movable in the same angle and direction to the pivot arm ( 13 ), preferably by the pivoting movement of the pivot arm via a driver stop ( 20 , 21 ) or . Like. is portable.

6. Device according to one of claims 1 to 5, characterized in that the lever arm ( 13 ) is rotatably arranged on a koa xial to the pendulum arm ( 12 ) and on this rotatably mounted first sleeve ( 15 ) and / or the holding arm ( 17 ) is rotatably attached to a coaxial to the pendulum arm ( 12 ) and rotatably mounted on this second sleeve ( 18 ).

7. The device according to claim 6, characterized in that between the first and second sleeve ( 15 ; 18 ) a return spring ( 19 ) is arranged and the angular offset between the first sleeve ( 15 ) and the second sleeve ( 18 ) via a Stop ( 20 ) is Festge to a minimum offset, the stop ( 20 ) preferably also forms the driver, and / or a return spring ( 22 ) is arranged between the pendulum arm ( 12 ) and the first sleeve ( 15 ).

8. Device according to one of claims 1 to 7, characterized in that the cover of the work on the Stützmit tel ( 2 ) by means of brackets ( 7 ) can be fastened, which preferably before relative to the position of the first contact of the friction roller ( 14 ) the sheet surface to the fold ( 1 D) arranged offset and positioned and / or executed with a curvature to cause a bulging of the umzublät terenden sheet ( 1 A).

9. Device according to one of claims 1 to 8, characterized ge indicates that the first and / or the second sleeve with one initiating and executing the pivoting movement Gear arrangement are connected.

10. The device according to one of claims 1 to 8, characterized in that the pivoting movement of the first and / or the second sleeve via guide elements, a link or a cam guide can be effected by the housing with a fixed to the electric motor ( 9 ) ( 5 ) connected guide plates ( 30 , 31 , 32 ) and to cooperate with these, with the first and / or the second sleeve ( 15 , 18 ) connected cam pins ( 33 , 34 , 35 ) or the like .

11. Device according to one of claims 1 to 10, characterized in that a rotation of the friction roller ( 14 ) in the pivoting direction (A) of the swivel arm ( 12 ) is locked and only in the opposite direction by means of a freewheel he is possible.

12. The device according to one of claims 1 to 9, characterized ge indicates that the gear arrangement the first sleeve with the friction roller at or near the turning point into one the position corresponding to the rest position relative to the pendulum arm and swings back relative to the holding arm.

13. Device according to one of claims 1 to 12, characterized ge indicates that the pendulum movement of the pendulum arm is limited to about 100-110 ° and / or the backward movement takes place automatically, for which purpose preferably switches or a Switching electronics or the like are provided.

14. Device according to one of claims 1 to 13, characterized in that for a page back a second direction ( 10 B) is provided, which is preferably arranged in the same housing ( 5 ) below the sheet music ( 1 ) on the music stand ( 2 ) is.
