Patent ID: 8602978

Claim:
A temperature control apparatus for an endoscope, the temperature control apparatus comprising: a heater arranged in an endoscope, the heater being heated as a result of supply of power; a power line for supplying power generated by a power source to the heater, the power line being connected to the power source; a temperature detection section that detects a temperature of an object to be heated, the object to be heated being heated by the heater; a semiconductor switch provided on the power line, the semiconductor switch performing switching between supply and shut off of the power to the heater; a control section that controls the semiconductor switch according to a temperature detection result from the temperature detection section to perform temperature control for the object to be heated, and performs heating stopping control to turn the semiconductor switch off based on the temperature detection result; a mechanical switch provided on the power line, the mechanical switch performing switching between continuity and shut off of the line; and a heating stopping circuit that if an abnormality occurs in temperature control for the heater, performs heating stopping control to turn the mechanical switch off.
