PURPOSE:To shorten a molding cycle by providing a detection device having one set or more of detectors in a charging device and detecting charging material in the charging device and in a mold by the same detection device. CONSTITUTION:After the detection of inserted parts 11 charged into an insert part holder 15 of a charging device is confirmed by beam sensors 20, 20a, the parts 11 are dropped into a lower mold 12. Then, an elevation plate 23 is moved down by a cylinder 26, and sensor rods 22, sensing rings 24 are placed on the parts 11 dropped in the mold 12. At this time a light is projected by the sensor 20, received by the sensor 20a to detect and confirm whether the parts 11 are accurately charged in the mold 12 or not. When the all parts 11 are charged in the mold 12 and confirmed, the plate 23 is raised by the cylinder 26, the rods 22, the rings 24 are pulled up, and the charging device is returned to the original position.
