  • Electronic endoscope apparatus and electronic endoscope system
    Patent number: 10231610
    Abstract: Electric power of a required voltage is supplied to an endoscope distal end portion, and a distal end temperature is prevented from being higher. An imaging device having an imaging element, and its peripheral circuit and a first circuit part including a first regulator as a power circuit are built in the endoscope distal end portion. The first circuit part is connected to a second circuit part via a cable. The second circuit part includes a second regulator supplying electric power to the first regulator. By the overcurrent detection function of a temperature detecting unit or a regulator arranged, when at least one abnormality of a temperature abnormality and an overcurrent in the distal end portion is detected, the output of at least one of the first regulator and the second regulator is stopped, and supply of power to the distal end portion is stopped.
