SOLUTION: Respective C divisions 52c, 53c are arranged to face in parallel at a protruding part 126 at respective C sections 52b, 53b which protrude from one end side of respective A sections 52a, 53a, and a third bus division unit 56 and a fourth bus division unit 57 are arranged at the protruding part 126 to extend in a direction at right angles to buses 52, 53. As a result, it is possible to restrain the instruction area from being extended to extension lines of the respective A sections 52a, 53a, and it is possible to restrain the area from being increased when the C sections 52c, 53c are expanded.</p> |
