Abstract: To provide an electronic upright piano providing a key touch of an acoustic upright piano. An action load simulation member (2) provided in the electronic upright piano is composed of a wippen (15) rotating and rising when a depressed key (11) is rotated, a jack (17) rising together with the wippen (15) until a jack tail (17a) contacts a regulating button (16), a hammer butt (18) rotatably supported by a center pin (18b) for contacting or leaving the jack (17), a hammer shank (21) connected to the hammer butt (18) and provided with a hammer (23), and a hammer stopper (32) which can contact the tip of the hammer (23). The wippen (15), the jack (17) and the hammer butt (18) are rotated about separate axes, respectively. In the electronic upright piano, the let-off timing is the same as that in an acoustic upright piano.

Abstract: There is provided a method of assembling an upright piano. The upright piano is divided into a plurality kinds of units. The plurality of kinds of units are each separately assembled, and these plurality of kinds of units thus assembled are joined to each other, to thereby assemble the upright piano.
