RADIO DEVICE FOR OBTAINING INFORMATION ON INSIDE OF SUBJECT, RADIO SYSTEM FOR OBTAINING INFORMATION ON INSIDE OF SUBJECT, AND COMMUNICATION DEVICE

摘要

A communication apparatus (3) arranged outside a subject (1) has an external device (32) which sequentially transmits control signals. A capsule endoscope (2) is introduced inside the subject (1). Thereafter, a system control circuit controls a driving of an intra-capsule function executing circuit so as to start driving at a previously set given time, by supplying driving power to the intra-capsule function executing circuit to control the driving thereof based on a result of detection by a control-signal detecting circuit which is provided in the capsule endoscope (2) and which detects a discontinuous state of input of the control signals. Thus, a collection and transmission of images inside the subject can be performed accurately.
