A paper floating detection apparatus is arranged at a conveyance path of a conveyance device which holds paper on a conveyance surface and conveys the paper in a conveyance direction while causing a surface of the paper to face a droplet ejection head. The process may further comprise, after sintering the extruded tube, layering an electrolyte onto the tubular anode; and, after layering the electrolyte, layering a cathode onto the electrolyte. The circuit board is introduced into a holder which comprises at least one bearing point, wherein the actuator is guided. If the current frame is found to be unstable, corner points are obtained from the current frame. The central entity manages this information and makes it accessible to applications and terminals. In the broadcasting station, edit is performed based on the encoded data DVA of low resolution and edit decision list is transmitted to video recording apparatus.
