the desk of the folding music holder with a support part and a rest running approximately transversely to it consists of at least two folding hinged portions , in particular rest parts , which hang together through hinge bands . each hinge band is preferably designed as material thin point in the area of a groove between the hinged portions . the rest or the entire desk can thus be formed as a one - piece plastic part , where the rest in the operating position provides a flush work surface .
