1 faces left and the right holding bar 61 faces right, so that the actual standing operation is performed by putting each finger of each hand into each finger insertion recess 25 from the outside of each holding bar 61, and This can be performed by raising the presser bar 61, and the raising operation is easy. On the other hand, when the use of the presser bar 61 is finished, the front end 61 a of the presser bar 61 is pressed from above, and the presser bar 61 is moved into the housing groove 2 of the case body 20.
Easily fits in 6.

According to the present embodiment, the holding rod 61 is
When used, it stands upright, so that even if an external force from above is applied to the distal end 61a of the holding rod 61, the holding rod 61 automatically rotates in the sideways direction, Danger is reduced compared to In addition, when not in use, since it is stored sideways in the music press unit 10, it does not become an obstacle. Therefore, the musical score can be safely held down when not in use and without hindrance.

Furthermore, since the music pressing unit 10 is manufactured in advance as an independent unit and is attached to the music receiving unit 5, parts for the music pressing mechanism are individually mounted on the music receiving unit 5. Compared to the case,
The manufacturing process is simplified. Therefore, assembling can be facilitated by unitizing the music pressing mechanism.

When the holding bar 61 is stored in the music holding unit 10, the holding bar 6 is inserted into the recess 25.
Since the one end portion 61a is extended, a finger is inserted into the finger insertion concave portion 25 to raise the end portion 61a, whereby the holding rod 61 rotates in the rising direction. Therefore, it is possible to easily perform the raising operation of the pressing bar 61 when pressing the music score.

Further, the function of defining the range of rotation of the holding rod 61 is performed by the stopper portion 27 and the stopper surface 45a.
Since it is a part integrally formed with the part No. 0, the configuration is simple and contributes to facilitation of assembly.

The music pressing unit 10 is arranged symmetrically in the music receiving unit 5, but has the same configuration, so that only one type is required and the manufacturing cost is reduced.

In the present embodiment, the case where the music holding unit is provided on the top plate is exemplified. However, if the music holding unit is configured to receive the lower edge of the music, the place where the music holding unit is provided may be provided. However, the present invention is not limited to the top plate, and may be on a roof plate or a dedicated music stand, and may be on a panel surface for a desk keyboard instrument.
