Device for reducing electromagnetic interference in recording and/or reproducing apparatus with radio receiving function. |
摘要 |
<p>A disc recording and/or reproducing apparatus with a radio receiving function wherein a recording/playback unit (2) having a high-frequency clock generator is housed in a shield case (11), and both input and output signals (14) of the recording/playback unit (2) are transferred to and from other circuits via a pair of filters (12,13) disposed inside and outside the shield case, or such input and output signals are transferred via opto-electric convertor and electro-optical convertor (12,13) disposed inside and outside the case, so that any unrequited high-frequency components radiated from input and output connection leadwires piercing through the shield case (11) can be suppressed to consequently achieve remarkable reduction of the high-frequency noise entering into the radio receiving unit. <IMAGE></p> |
