Abstract
PURPOSE:To easily execute discrimination, to elevate vibration resistance, and also to make a device small-sized, by recognizing the left and right directions by light emitting elements corresponding to the left and right directions, respectively, and displaying a shift of the direction by a long or short flickering period of the light emitting element. CONSTITUTION:A receiving output of a radio signal R received by an antenna 31 is divided into the first direction and the second direction by a switching circuit 32. An output of this circuit 32 is detected 32, and a detected output D is held by a capacitor of a sample holding switch (SHS) 35. Subsequently, a detected output DI correspoding to the first direction and a detected output DII corresponding to the second direction are provided to a differential ampifier 37. In accrodance with whether an absolute value of an output of this amplifier 37 is large or small, oscillation frequency of an oscillator 38 is varied high or low. That is to say, when a difference between the output DI and DII is large, a pair of light emitting element 39-Ior 39-II is made to emit light for a short flickering period, and when an aeroplane, etc. are exactly directed to a station to be homed, the light emitting element is scarcely lighted. On the other hand, the light emitting element is scarcely lighted. On the other hand, in case of a shift in the left or right direction, the output DI or DII becomes large or small, and it is displayed by flickering of the light emitting element 39-Ior 39-II.
