Abstract: To take security into account and increase user friendliness, an information processing device includes: an input unit to which information is input; an extracting unit extracting predetermined words from the information input to the input unit; a classifying unit classifying the words extracted by the extracting unit into first words and second words; and a converting unit converting the first words by a first conversion method and converting the second words by a second conversion method, the second conversion method being different from the first conversion method.

Abstract: Provided is an outer cover attachment structure which achieves the reduction of burden for collecting and recycling used products from the market, the reduction of replacement parts, and cost reduction of reproduced products. A housing portion housing the removed fixation members or connection members is provided to at least one of the paper feed trays. In the paper feed tray, a housing space is set behind the end face in the paper feed direction of the transfer paper. This position shall be a position that will not have an adverse effect on the paper feeding operation or paper replenishment of the paper feed tray. Two screw holes are provided inside the housing space, and a screw for fixing the fixation members to be housed are inserted into the screw hole so as to fix the fixation member or housing container.
