In order to prevent a replacement of the needle plate in the situation not suitable for replacing the needle plate, a needle plate detachable mechanism has a needle plate fixing unit capable of being switched between a fixed state where a needle plate is fixed to a sewing machine body and an unfixed state where the fixed state is released; and a switching mechanism which is connected with the needle plate fixing unit for switching the needle plate fixing unit between the fixed state and the unfixed state, wherein the needle plate fixing unit is prevented from being switched when the needle is positioned below an upper surface of the needle plate or when the sewing machine motor is driven.
