An object of the present invention is to provide a technical polymerization apparatus capable of carrying out one of the pre-polymerization and the main polymerization with an apparatus, a plurality of light sources having at least two optical axis directions, A polymerization space is formed on the inside, a lid that switches between the formation of an opening that communicates the inside and outside of the polymerization space and the closing of the opening, a sensor that detects the formation of the opening by the lid and the closing of the opening, and a signal received from the sensor Then, based on the formation of the opening and the closing posture of the opening, the light source of two or more directions having different optical axis directions is lit in the closing posture of the plurality of light sources, and in the posture in which the opening is formed And control means for turning on light sources having a smaller number of directions than the posture of closing the opening.仮重合及び本重合のいずれの重合も１つを装置で行うことができる技工用重合装置を提供することを目的とし、光軸の方向が少なくとも２方向である複数の光源と、光源を覆いその内側に重合空間を形成するとともに、重合空間の内外を連通する開口の形成及び該開口の閉鎖を切り替えるフタと、フタによる開口の形成及び該開口の閉鎖を検知するセンサと、センサから信号を受信して、開口の形成及び該開口の閉鎖の姿勢に基づいて前記複数の光源のうち開口の閉鎖の姿勢では光軸の方向が異なる２方向以上の光源を点灯させ、開口が形成された姿勢では開口の閉鎖の姿勢よりも少ない方向数の光源を点灯させる制御手段と、を備えるものとする。
