The apparatus includes as essential components an opposing pair of chucking members for supplementarily supporting a molded product in the clamped state while restrictively locating it at a predetermined position, and a suction pad located in alignment with the predetermined position of the molded product for grasping the latter by the action of suction. In an alternate embodiment, two chuck arms having respective suction pads at their ends are moved into contact with the shutter from opposite sides. With the invention the molded product can completely be extracted from an injection molding die in cooperation of the chucking members with the suction pad.

Method for extracting molded product from injection molding die

A used lens-fitted photo film unit has a photo film containing section and a front cover. The photo film containing section has a first retaining hook. The front cover has a second retaining hook. The second hook is retained on the first hook, and couples the front cover to the photo film containing section. In a disassembling station, the photo film unit is set in a predetermined orientation. An access plate is advanced toward the photo film unit. The access plate flexes the first hook apart from the second hook, and disengages it from the latter. The access plate is retracted while the front cover is captured by the access plate, thereby to remove the front cover from the photo film containing section. In a preferred embodiment, a flash device from the used photo film unit is supported so as to face upward a flashing face of the flash device. Cleanser liquid is sprayed on the flashing face. Cleaning tape comes in contact with the flashing face. The tape is moved on the flashing face while keeping the tape in contact with the flashing face, and wipes and cleanses the flashing face.
