Various embodiments storing volumes of data in a data storage system, including one or more data storage containers, the data storage containers being thin-provisioned to provide virtual data storage capacity which is greater than a real data storage capacity of the data storage hardware are provided. An upper arm rotatably bridges between an upper end of a push rod and the front fork, and the length of this upper arm is equal to the length between a linking point of a lower end section of the push rod of the axle support arm and a linking point of the arm holder, and is substantially parallel with this length. The color filter unit is disposed in a groove of the transparent substrate for transforming a beam of light sent to the color filter unit into the beam of light of a predetermined hue. The primary transceiver unit and optical router communicate by means of light beams which are transmitted through the atmosphere. The mobile terminal further accepts a selection of image data from plural displayed thumbnails and wirelessly transmits the selected image data with the address to the image forming device.
