PURPOSE:To prevent an unnecessary flickering operation in the course of an automatic channel selecting operation of a diversity receiving device, by constituting it so that the operation of each turn-on indicator is always fixed to either the turn-on state or the turn-off state. CONSTITUTION:A turn-on indicator 1 biased in the forward direction is turned on by a control signal 4 supplied from a controlling circuit 3 in the course of an automatic channel selecting operation. Other indicator 2, however, is turned off since the control signal is biased in the reverse direction through an inverter 5. After that, each turn-on indicator 1, 2 is fixed to said operating states. |
