Provided is an endoscope system (100) provided with an endoscope main unit (1) including a shaft (10), an operating portion (20), and an image-acquisition unit (15) an arm (41) that supports the endoscope main unit (1) and that can change the attitude and the position of the endoscope main unit (1) by using a plurality of joint portions whose rotating angles can be changed about respective predetermined rotation shafts a memory that records angle information of the respective joint portions a CPU and a mode-switching switch (23) that switches between a recording operating mode in which an operator (D) holds the operating portion (20) and the changes the attitude and the position of the endoscope main unit (1) and an automatic operating mode in which the attitude and the position of the endoscope main unit (1) are changed by the CPU, wherein, in the case in which operating mode is switched to the automatic operating mode from the recording operating mode, the CPU reproduces changes in the rotating angles of the respective joint portions in time-series in reverse order based on the angle information recorded in the memory in the recording operating mode, thus returning the attitude and the position of the endoscope main unit (1) to the initial state of the recording operating mode.
