Abstract

The present invention provides an electric device and a guide system for subject. The 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.

Description

technical field [0001] The present invention relates to an electronic device including a plurality of circuit blocks, and a system introduced into a subject including a receiving device including a plurality of circuit blocks. Background technique [0002] In recent years, swallow-type capsule endoscopes have been proposed in the field of endoscopes. This capsule endoscope is provided with an imaging function and a wireless communication function. Capsule endoscope has the function of following the peristalsis of internal organs such as the stomach and small intestine in the body cavity after being swallowed by the subject (human body) for observation (inspection) and before it is naturally discharged. Movement, moving within it, and shooting in turn. [0003] While moving in the body cavity, the image data captured by the capsule endoscope inside the body is sequentially transmitted to the outside by wireless communication, received by an external receiving device, subjec...
