A liquid jet head includes head modules each having a nozzle plate with a nozzle orifice and a passage-forming substrate having a pressure-generating chamber. These flexible sheet portions are adapted to be detachably sealed together along their peripheral edges, thereby providing for the enclosure of a medical device. When the ink sheet cartridge is accommodated to a facsimile device, a thermal head and a platen are positioned at the central open space. The communication oil path allows the first and second oil accumulating parts to communicate with each other. The system includes a gripper head assembly extension control module, capable of controlling multiple travel distances of the gripper head assembly in a single packing cycle, a product assembly detection module, and a packaging release control element for subtle separation of individual packed containers. Next, the invention partially etches unprotected portions of the conductive layer.
