The operator grips the casing 110 by hand in a state in which the cover 140 is closed when photographing the oral cavity state. Therefore, the open / close detection unit 141 transmits a detection signal to the control unit 153, and the control unit 153 controls the power supply unit 157 to supply power to the intraoral imaging camera 120.

After the operator completes photographing the teeth with the intraoral photographing camera 120, when the dual oral camera 100 is separated from the oral cavity and the face is photographed, the operator moves the cover 140 downward to open it. As shown in FIG. 4, the oral cavity imaging camera 130 is exposed to the outside as the cover 140 is opened. At this time, since the positions of the first sensor 141a of the cover 140 and the second sensor 141b of the extra-oral imaging camera 130 are shifted, a weak magnetic force detection signal is transmitted to the controller 153. If the magnetic force is weak, the control unit 153 determines that the cover 140 is opened, and the power supply unit 157 stops supplying power to the intraoral imaging camera 120 and supplies power to the extraoral imaging camera 130. Control to supply.

Therefore, the user switches the power supply from the dual oral camera 100 to the extraoral imaging camera 130 in one operation of opening the cover 140. Thus, the process of operating the dual oral camera 100 for the procedure may be convenient.
