An endoscope system comprises an endoscope for industrial use, a remote control unit, a light source unit, a CCU, a motor-driven angling unit, a drum rotation variable resistor, a power supply unit, a buzzer, and a microphone. These apparatuses constituting a basic system are controlled by a system control CPU incorporated in a control unit. The system control CPU in the control unit is connected to an angle control CPU in the motor-driven angling unit and a DSP control CPU in the CCU over signal lines. Moreover, the system control CPU is connected to a remote control CPU in the remote control unit through a connector over a signal line. Consequently, the complex functions of the apparatuses are controlled in a centralized manner. This results in improved ease of use.
