Concentration of metal element which promotes crystallization of silicon and which exists within a crystal silicon film obtained by utilizing the metal element is reduced. The drive mechanism may include first drive magnets respectively disposed on four side faces of the lens drive device, a second drive magnet for restraining inclination which is disposed on at least one of four corners of the lens drive device, and a drive coil which is wound around in a substantially octagonal shape. At least one damage line is formed within the strengthened glass sheet. The apparatus may further include an infant mobile including a support arm, a housing suspended by the support arm, and one or more hanging elements suspended from the housing. A fan speed controller determines fan speed based on temperature using one of two profiles. JPEG encoding tables that were used in the encoding of each of the plurality of tiles are determined based upon the headers, the JPEG-encoded data of respective ones of the plurality of tiles is arranged based upon the sameness of the JPEG encoding tables, and RST marker codes are inserted between the items of JPEG-encoded data of respective tiles, thereby creating a string of encoded data.
