Electronic Apparatus
First Claim
1. An electronic apparatus, comprising:
- a first circuit block which has at least a first ground terminal and receives a ground potential via the first ground terminal;
a second circuit block which has at least a second ground terminal, receives the ground potential via the second ground terminal, and generates a noise signal of a level higher than a level of a noise signal of the first circuit block on being driven; and
a conductive shield member which receives the ground potential via the first ground terminal.

Abstract
A processing device (2) includes an analog circuit block (6), a digital circuit block (7), a casing (12) which houses elements including (6) and (7) and serves as a conductive shield member, and a connecting connector (13) which has functions, for example, of electrically connecting the casing (12) and a first ground terminal (6a) provided in the analog circuit block (6). Level of noise signals generated from the analog circuit block (6) is lower than the level of noise signals generated from the digital circuit block (7). Therefore, when the casing (12) is electrically connected to the first ground terminal (6a) provided in the analog circuit block (6), the casing (12) can maintain a stable potential thereby more effectively working as the conductive shield member. Thus, leakage of the noise signals generated at driving of internal electronic circuitry is effectively suppressed in an electronic apparatus such as a receiving apparatus.
