する時計付ラジオ受信機。A half-wave rectified voltage is supplied from a rectifier circuit that half-wave rectifies an AC power supply through a half-wave rectified voltage supply path to a dynamic clock display unit that has a built-in light-emitting display element and dynamically lights up the light-emitting display element. In the radio receiver with a clock, a capacitor that removes noise components superimposed on the half-wave rectified voltage and does not have a smoothing effect is provided between the half-wave rectified voltage supply path and the ground. A radio receiver with a clock.
