An in-vivo information acquiring system includes a body-insertable apparatus that includes a magnetic field responding unit, acquires in-vivo information, and transmits the in-vivo information to the outside a magnetic field generator that generates a magnetic field for the responding unit a magnetic field control unit that controls a generation of the magnetic field a receiving unit that receives the in-vivo information transmitted from the apparatus a processing unit that processes the in-vivo information a display unit that displays the processed in-vivo information on a screen an alarm lamp that notifies a generation state of the magnetic field and a control unit that controls light emission process of the lamp such that an operator who visually identifies the in-vivo information is less disturbed by the light. The control unit performs control such that the lamp emits light upon no magnetic field and stops the generation of light upon the magnetic field.
