• a main case;
• a plunger separably coupled to the body attachable unit, and installed to be movable from a first location to a second location inside the main case to discharge the body attachable unit in a direction of an outside of the main case;
• a needle separably coupled to the body attachable unit to be inserted into the body of the user together with the sensor unit;
• a needle separation unit configured to move the needle in a direction opposite to a discharged direction of the plunger to separate the needle from the body of the user, wherein the needle separation unit comprises a locking part, and the locking part is configured to be assembled to the plunger in a way in which the locking part engages with one side of the plunger, wherein the needle separation unit comprises:
• a support column having the locking part, a needle holder movably coupled to the support column to be coupled to one end of the needle, and a needle separation spring configured to apply an elastic force to the needle holder in a direction of separating the needle from the body of the user, and wherein the support column is configured to be assembled to the plunger by forming an assembly together with the needle holder and the needle separation spring;
• a support column hook to which one end of the needle separation spring is connected is provided inside the support column,
• the needle holder comprises a needle holder hook to which another end of the needle separation spring is connected, and
