PURPOSE:To give information of the standby state cleary by letting an operator of a player know the standby state by moving a light source of a light emitting diode string. CONSTITUTION:A control signal, for insance, a triangular wave of 1Hz, from a control signal generating circuit 1 is inputted to a control input terminal 2 of a light emitting diode drive circuit 3. When the operation is the standby state, by generating said control signal, light emitting diode strings 4, 5, 6, 7 and 8 emit light sequentially, for instance, in the order of 4, 5, 6, 7 and 8 according to the control signal, and flicker repeatedly. Consequently for a person to watch the light emitting diodes 4-8 it is likely to seem that the point light source is reciprocated between the light emitting diodes 4-8. The state in which the light source is shifting enhances recognizability of a player operator. |
