The instant breaking unit is operated by a signal of a controller. The instant breaking unit includes a motor(36) and a disk knife(38). The disk knife is installed at the end of a shaft of the motor. The disk knife has an oval shape. The shaft of the motor is supported by a fixing pin(316) installed on a side of the frame. A compressed spring is interposed between a hole on the side of the frame whose outer side is stopped and the fixing pin to make the disk knife push the glass bulb.
