An insertion device includes an insertion section extending along a longitudinal axis, a rotor provided in the insertion section rotating around the longitudinal axis, and an assistance tool attached to the insertion section in a state to cover the rotor from an outer peripheral side. The assistance tool rotates around the longitudinal axis together with the rotor when press force is applied from a first projection of the rotor to a second projection of the assistance tool by a rotation of the rotor. An angular position of the second projection around the longitudinal axis can be recognized from an outside of the assistance tool.

A system for implementing an electrical rotary joint in a large-diameter system using relatively small-diameter capsule slip rings is described herein. The system includes a system rotor that rotates about a system axis of rotation, and a system stator that is stationary with respect to the system rotor.

Technologies pertaining to a rotary electrical contact device are described herein. A rotary electrical contact device comprises a first sheave that is disposed about a first axis and a second sheave that rotates about the first axis or a second axis that is parallel to the first axis. The device further includes two planetary sheaves that revolve around the first and second sheaves, and a belt that makes contact with each of the sheaves, the belt comprising a co-wound inner helical coil and outer helical coil. As the first sheave rotates, the planetary sheaves revolve about the first and second sheaves and cause the belt to deform and roll along the second sheave. The belt makes rolling contact with the four sheaves. The belt is electrically conductive such that as the belt rolls along the sheaves, the belt maintains electrical contact between the first sheave and the second sheave.
