Abstract:
An optical information recording/reproducing apparatus comprising:a laser light source for illuminating an information recording medium with laser light;an optical-electrical converter for providing an electrical signal corresponding to information recorded on said recording medium by using reflection light by said recording medium; anda high frequency imposing circuit for switching ON and OFF said laser light, whereinsaid high frequency imposing circuit and a terminal of said laser light source are enclosed by a conductive shield case,said shield case has a pair of half cases each having a wall partially overlapping with a wall of the other half case,a capacitor is coupled between at least one lead line for coupling said high frequency imposing circuit and said laser light source with an external circuit, and ground,a junction of said capacitor and a lead line for external connection is located close to a wall of said shield case, andsaid lead line coupled with said capacitor for external connection is taken out of the shield case through a gap between the overlapped walls of two half cases.
