SCORE EXCHANGE DEVICE

摘要

A device for exchanging single sheet scores surely sheet by sheet in which the score can be replaced quickly and the device can be made compact with small number of components. The score exchange device comprises a plurality of single sheet scores (B), and a score stand (A) for laminating the plurality of scores (B) and removing them sheet by sheet wherein the score (B) has a sheet shape and provided, at a part thereof, with a supporting portion (2) composed of a magnetizing material and having a pinhole (3). The score stand (A) consists of a pin (12) for supporting the plurality of scores (B) under a state where the pin (12) is passed through the pinhole (3) in each supporting portion (2) of the plurality of laminated scores (B), a magnet (20) arranged at a position for magnetizing the supporting portion (2) on the uppermost one of the laminated scores (B), and a mechanism for pushing out the supporting portion (2) on the uppermost score (B) while resisting against the magnetizing force of the magnet (20) wherein the clearance between the top surface of the pin (12) and the magnetizing surface of the magnet (20) is larger than the thickness of a sheet of supporting portion but smaller than the thickness of two sheets of supporting portion.
