In addition, electronic musical instrument is provided with an openable and closable cover plate 19; a long support rod 21 for supporting the cover plate 19, by setting 20° for the angle of the cover plate 19; and a short support rod 22 part for supporting the cover plate 19 by setting 5° for the angle of the cover plate 19. The electronic musical instrument is provided with a contact 25 on the long support rod 21, and a switch 26 on a part facing it. When the cover plate 19 opens at an angle of 20°, the contact 25 comes into contact with the switch 26, and the sounding system goes into a state capable of sound effect generation. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
