（図示しない）で電気的に接続していた。 Therefore, conventional electronic pianos have adopted structures as shown in FIGS. 3 and 4. That is, in the case shown in Figure 3, a metal foil b such as aluminum is adhered to the upper surface of a bottom plate a made of plywood, and a cover c made of, for example, a vinyl chloride-coated steel plate having an electrical shielding function is attached to the steel plate part. Attach the bottom plate a.
It can be opened and closed by a hinge d with another piece attached to the rear end of the top surface.The one shown in Figure 4 has a cover c of the same structure as the one described above, with one piece attached to the steel plate part of the cover c, and the top surface A hinge d with another piece attached to the rear end of the lower surface of the bottom plate a covered with metal foil b is used to freely open and close the metal foil b and the steel plate part of the cover c using a conductor or the like (not shown). was connected to.

なければならない。(Problems to be solved by the invention) The structure shown in Figure 3 is simple because the electrical connection between the metal foil b of the bottom plate a and the cover c is made by the hinge d. Since the end of the rear end surface is exposed, the end surface must be treated with makeup or the like. In addition, in the case shown in the fourth figure, since the end of the rear end surface of the bottom plate a is covered by the cover c, there is no need to apply makeup or other treatments to the end surface of the bottom plate a.
The metal foil b of the bottom plate a and the cover c must be connected with an electric wire or the like.

徴とする。(Means for Solving the Problems) In order to achieve the above object, the present invention has a hinge at the rear end of the bottom plate having a conductive layer on the upper surface, at least a part of which is made of a conductive material and has an electrical shielding function. In the hinge structure of an electronic musical instrument formed by connecting covers, one piece of the hinge made of a conductive material is bent and attached to the upper surface of the bottom plate so that a part thereof faces the rear end surface of the bottom plate. The rear end surface of the bottom plate is covered with the cover, and the conductive layer and the conductive material of the cover are electrically connected via the hinge.
