Conventionally, vertical pianos have been arranged so that the keyboard section can be stored inside the exterior main body, improving transportability and space efficiency during storage. It is known that the device is detachably or rotatably attached to the main plate 2 of the device.
In this case, the piano shown in the figure has a pair of fixing fittings 3,
4 and setscrew 5 to fix the arm 6 to the inner surface of the main board 2, and when storing, remove the setscrew 5 of one of the fixtures 3.
is removed, the keyboard section 1 is rotated downward using the rear end of the other fixture 4 as a rotation fulcrum, and is housed in the lower space within the exterior main body 7.

However, in the case of such conventional vertical pianos, it is necessary to remove the setscrews 5 of the fixing bracket 3 when storing or pulling out the keyboard section 1, which is troublesome and the screw holes in the main board 2 are not properly aligned. This tends to result in holes, making it impossible to stably fix the keyboard section 1. Therefore, as a means to solve this problem, it may be considered to embed the nut in the inner surface of the main plate, but this would increase the number of parts and make the assembly work complicated.

This idea was made in view of the above-mentioned points, and consists of disposing a keyboard section on the exterior body so that it can freely rotate in the vertical direction, and disposing a receiving plate spring on the inside surface of the exterior body to temporarily hold the keyboard section. A stay that is rotatably housed along the bottom surface of the keyboard and has a full length changing mechanism that expands and contracts in the longitudinal direction as it rotates is provided, and the lower end of this stay is attached to the frame. With an extremely simple structure in which the keyboard section is held in a playable state by being received by the stay receiving section, stability is good, there is no rattling, and the keyboard section can be stored easily and quickly. It provides a vertical piano.

When setting the keyboard section 12 to a playable state, the lower front plate 16 is opened forward, and when the keyboard section 12 is held by hand and rotated upward, it is temporarily held by the receiving plate spring 32. In this state, the stay 31 stored on the lower surface of the shelf board is pulled out, and its lower end is attached to the stay receiving part 40 of the frame 18. Thereafter, when the stay 31 is rotated to raise the cylinder 31, the keyboard section 12 is pushed up and comes into contact with the stopper 45, thereby completing the setting operation of the keyboard section 12. As a result, the keyboard section 12 is stably and reliably fixed at a predetermined height, and wobbling during performance is prevented.
