The present embodiments perform active volume restores on actively running initial operating systems in an active partition. Using the tracking result of tracking a group of three or more candidate areas, a plane assumption verifier determines to which of the preset planes these candidate areas belong. A plurality of generally vertical shafts each has a respective workpiece retaining element secured to one end thereof. The plurality of released beams preferably includes at least two released beams lengthwise extending outwardly from the switch detecting circuit region to different predetermined lengths and at least two released beams lengthwise extending outwardly from the switch detecting circuit region to substantially the same predetermined lengths. The prepared text file is automatically transmitted to the destination electronic messaging address.
