An image forming apparatus has an image carrier with rotary shafts extending from both ends that are rotatably supported on an apparatus body by bearings. The semiconductor wafer is cut together with a part of the adhesive layer by using a first blade of which cutting depth reaches the adhesive layer. The pivot-arm actuator pivotally latches to the pull-actuator and to the cage assembly or module receptacle. The inter-device packet transfer controller controls the inter-device packet transfers such that multiple fragmented packets created from a same original packet are collected by the same internetwork device, the fragmented packets being packets created by dividing a single original packet into multiple parts. There are pre-created tech-libraries for the instances. An extension member extends from the butt of the stock to the latch.
