Title:
DISPLAY UNIT FOR RECEIVER
Document Type and Number:
Japanese Patent JPS5578636
Kind Code:
A
Abstract:

PURPOSE: To display the reception frequency through a simple circuit by installing the switch circuit which is switched in sequence according to the variation of the frequency and the switch circuit which is switched with every frequency band.

CONSTITUTION: Light emitting diodes D1∼D18 of display unit 36 are provided along frequency scale 41. These diodes D1∼D18 are controlled by output A∼F of the 1st switch circuit which are switched in sequence by the variation of the frequency contained in tuning frequency switching variable voltage source 34 of the receiver plus output A∼C of 2nd switch circuit 35 which are switched coupling to reception band change-over switches S1∼S6. And the light emitting diode corresponding to the reception frequency is lit up.
