Abstract
In an indicating device including indicating elements (1) such as for display of frequency in a receiver, a driver circuit (2,3) operates the indicating elements, a control circuit (8) is interposed between a group of keys (7) for present operation and a gate circuit (4) for controlling the driver circuit, and the control circuit (8) produces output signals, in response to input signals supplied from the group of keys, to the gate circuit for lighting on and off the indicating elements. When the preset operation by a user is over the control circuit (8) ceases to produce output signal (P1) and output from pulse producing circuit (6) is at a normal level H. and this returns the indicating element 1 to its normal condition continuously indicating the received frequency. <IMAGE>
