Abstract:
1. An opening and closing mechanism for a keyboard cover of a musical instrument, the cover comprising a front cover half and a rear cover half coupled foldably by a hinge, the mechanism comprising: a first guide for guiding the front cover half backward at a front end thereof along a keyboard when the cover is opened; a second guide for guiding the rear cover half, which is foldable with respect to the front cover half at the hinge, backward at a front end of the rear cover half along the keyboard when the cover is opened, and for guiding the rear cover half obliquely downward at a rear end thereof after the keyboard so as to render the rear cover half substantially upstanding; and an inclination restrictor which is provided substantially at a midpoint of a rear guide part such that when the rear cover half is moved obliquely upward and downward while opening and closing the keyboard cover, the rear cover half slides on the inclination restrictor, thereby restricting an inclination of the rear cover half.
