Patent ID: 7912434

Claim:
A receiving system comprising: a receiving apparatus; a first receiving antenna that includes; a rod-like member having a predetermined rigidity; and a first connector which is formed at one end of the rod like member and which serves to connect the first receiving antenna to the receiving apparatus; and a second receiving antenna that includes; a thin and flat shape antenna; a second connector for connecting the second receiving antenna and the receiving apparatus; and a cable that electrically connects the thin and flat shape antenna and the second connector, wherein the receiving apparatus includes at least a receiving circuit performing a predetermined receiving processing on radio signal received through one of the first receiving antenna and the second receiving antenna; before a body insertable device is inserted into a subject, the first receiving antenna receives a first radio signal transmitted from the body insertable device while being arranged near the body insertable device, to determine whether the body insertable device operates normally; and when the body insertable device is inside the subject, the second receiving antenna receives a second radio signal transmitted from the body insertable device, a position of the thin and flat shape antenna being changed to adjust the position and an orientation direction of the thin and flat shape antenna so as to minimize a receiving condition of the second radio signal transmitted from the body insertable device.
