Abstract

The invention provides an electronic device and a system for introducing into a subject. The processing device (2) has: an analog circuit block (6); a digital circuit block (7); a housing (12) with a built-in analog circuit block (6) and digital A component of the circuit block (7), and functions as a conductive shielding member; and a connector (13), which is built in the housing (12), and has The function of the first ground terminal (6a) for electrical connection and the like. Compared with the digital circuit block (7), the level of the noise signal generated by the analog circuit block (6) is low. electrically connected so that the housing (12) maintains a stable potential and functions more effectively as a conductive shielding member. Therefore, in an electronic device such as a receiving device, it is possible to effectively suppress leakage of a noise signal generated when an internal electronic circuit is driven to the outside.

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...
