<p>PROBLEM TO BE SOLVED: To reduce wiring between boards.SOLUTION: Group unit control means for controlling a grouped light-emitting device is provided for each group. Performance control means is composed as group generalization control means for integrally controlling each group unit control means. A wiring board includes a first light-emitting board where the group unit control means for controlling a light-emitting device included in a first performance member is disposed, a second light-emitting board where the group unit control means for controlling the light-emitting device included in a second performance member is disposed, and a branch board for branching a transmitted data signal and for distributing the signal to the plurality of boards. In the first light-emitting board and the second light-emitting board, a signal cable of a data signal to be inputted to itself is connected but a signal cable output to a separately equipped wiring board is not connected.</p> |
