Instrument stand and keyboard instrument set

The present invention includes a keyboard lid which is constituted by a front lid and a rear lid whose lengths in the front-rear direction of a keyboard section provided in an instrument case are different from each other being foldably connected to each other by a coupling member, and openably and closably covers the keyboard section; a rotary fulcrum section which supports the rear end portion of the rear lid such that the rear lid is rotatable with respect to the instrument case, and by which the keyboard lid is mountain-folded and the front lid is held upright above the rear portion of the keyboard section when the keyboard lid exposes the keyboard section; and a guide section which guides the front end portion of the front lid in the front-rear direction of the keyboard section. Accordingly, the keyboard lid can be stably and smoothly opened or closed.

Keyboard lid opening and closing apparatus and keyboard instrument

An opening and closing mechanism for a keyboard cover that includes a front cover half and a rear cover half coupled foldably by a hinge. The mechanism comprises a first guide that guides the front cover half backward at a front end thereof along the keyboard when the cover is opened and a second guide that backward guides the rear cover half at a front edge thereof along the keyboard and guides the rear cover half obliquely downward at a rear end thereof after the keyboard, thereby rendering the rear cover half upstanding when the cover is opened. Thus, the second guide prevents the rear and front cover halves from lowering at their front and rear ends, respectively, thereby allowing the keyboard cover to be opened and closed smoothly.
