Apparatus for moving a member

A moving device for moving a tubular member, the moving device comprising:

• a housing having a hole through which the tubular member passes;
• a first roller and a second roller arranged to face both sides of the tubular member inside the housing and having outer circumferential surfaces configured to press the tubular member;
• an actuator configured to provide a driving force for rotating the first roller;
• a sensor configured to measure a movement amount of the tubular member;
• a controller configured to control the actuator on the basis of the movement amount of the tubular member;
• and
• a roller operation unit comprising:
• an operation member movably coupled to the housing and having one side coupled to a rotary shaft of the second roller, and
• a driving member configured to move the operation member, wherein the operation member is moved by the driving member to cause the second roller to move between a first position adjacent to the first roller and a second position farther from the first roller than the first position;
• and
• a shutter member positioned adjacent to the hole and coupled to the operation member, the shutter member being configured to open or close at least a portion of the hole,
• wherein, when the first roller rotates at the first position of the second roller, the tubular member between the first roller and the second roller moves by a frictional force.
