[0027] first reference figure 2 A grand piano embodying the present invention comprises: a piano case 51 , legs 52 , top plate 53 , cover bracket or top strut 54 , keyboard 55 , pedal mechanism 61 and stepless music stand 10 . Although there are action mechanisms, hammers and strings in the grand piano, for simplicity, figure 2 not shown in .

[0028] The piano case 51 is composed of various plate members such as a key base 56, side plates 57, sound boards 58, and desk rails 59, defining an internal space. The action mechanism and hammers are placed in the piano shell, and the strings are pulled over the soundboard 58. Top panel 53 is hinged to side panels 57 and is opened and closed by its user. The cover bracket 54 is pivotally connected at its lower end to the side plate 57 , and the top plate 53 rests on the cover bracket 54 . Therefore, the cover bracket 54 opens the top plate 53 .

Stepless music stand 18 is made up of platen 19, controller 20, attitude converter 21, limit switch 22 and stopper (not shown). Deck 19 is similar to deck 11 . Similar to the brake 14 , the brake prevents the music stand from slipping on the table rail 59 .

[0041] The attitude converter 21 includes a pair of mechanical boxes 21a and a pair of shafts 21b. The machine box 21a is fixed to the table rail 59, and the shafts 21b protrude laterally from the machine box 21a, respectively. The shaft 21b is connected to both side portions of the table 19 and holds the table 19 on the table rails 59 . Thus, the stepless music stand 18 does not require any hinges.

[0042] The mechanical boxes 21a are similar in structure to each other, and each mechanical box 21a has a one-way clutch and an electromagnetic release device. The one-way clutch i...
