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...
