SEITENWENDER

摘要

A device which will effectively turn a page, for example a page of a booklet of music, enabling a musician to play "hands free", has a book carrier (13) on a frame (11) and a number of page turner subassemblies (16) each with a disc (17) rotatable on an axle (12), each disc (17) having a notch (18) in its periphery, and also having an arm (20) radiating outwardly from the disc (17) and having a clip (57) to engage the page at the swinging end of the arm (20), and a spring (23) which will urge the arm (20) in a pivotal movement of the disc (17) in a page-turning direction, and an escapement mechanism (30) which co-operates with the notches (18) in the discs (17) to inhibit pivotal movement until released by a remote actuated controller (32).
