An endoscope system has an driving-section for driving an insertion-section having an instrument. The driving-section is supported by a pivoting section rotatively. The driving-section has two rollers facing each other. The insertion-section is disposed between the rollers. The insertion-section is extended or retracted by rotating the rollers if the rollers are disposed with respect to the extension/retraction direction. If the pivoting section is pivoted to be orthogonal to the extension/retraction direction, the insertion-section rotates around its axial line by the rotation of the rollers. By doing this, it is possible to rotate the instrument easily in the endoscope system for extending/retracting the instrument by electric power.
