<p>PURPOSE:To eliminate the need to interrupt a musical performance temporarily when a player turns the pages of the score by himself or herself during the musical performance by connecting a bar, fitted with plural teeth, to a hydraulic pressure device by a connection device. CONSTITUTION:The teeth 1 which are equal in length are implanted in the bar 2 at equal intervals. The bar 2 is connected by the connection member 3 to the hydraulic pressure device 4 fitted with suckers 6, and a switch 7 for expanding and contracting the rod 5 is connected to the hydraulic pressure device 4 by a cord 10. The bar 2, connection member 3, and rod 5 are made respectively detachable and then the device can be stored compactly. An upper button 8 and a lower button 9 which are stepped on with a foot are installed individually by giving a step to the switch 7 so that they are not misstepped on without visual confirmation. The L-shaped connection member 3 is made adjustable in length in respective directions so that the device can cope with a difference in the thickness of the score and is usable even for an upright piano.</p> |
