Holes into which the shaft center 11 is inserted freely are provided in the chamber 2, a hook-shaped movable plate 4 is fitted to the rear ends of an outer box 9, a shaft center 12 is provided at the front end of the horizontal part of the plate 4, the center 12 is inserted freely into one hole of an erecting plate 5 on which holes are provided in both ends, and the center 10 of the rear sides of the keyboard 3 is inserted freely into the other hole, and then the rear part of the keyboard 3 is moved up and down by opening/closing a display 6 where a sectoral projection bar 8 is fixed to near ends of a pivotally attaching part 7 opened and closed, thereby obtaining the very functional keyboard.</p> |
