PURPOSE:To report surely the receiving start of a reserved program, by generating the noice tone a fixed time before receiving of the reserved program, in the radio receiver which receives reserved programs automatically. CONSTITUTION:A fixed time is subtracted from time data, which is stored in memory 3 preliminarily, by substractor 7, and the substraction result is outputted to comparator 8 and is compared with the time signal from clock circuit 5; and only when they coincide with each other, the signal is outputted to sound synthesizing device 9. Sound synthesizing device 9 synthesizes sound on the basis of the signal from comparator 8 and generates the notice tone from speaker 10. Consequently, the driver completes arragement for receiving of required information. |
