An object of the present invention is to enhance search accuracy when additional data to be added to editing target data is searched using handwriting input. After blank spaces are removed and the controls attached, the two files are compared to determine additions, deletions and changes. In the inoperative position, the lateral air guiding elements are pushed over the central air guiding element so that they rest against one another by way of the end sections and completely cover or envelop the central air guiding element. Additionally, the full-width half-max value of the output optical energy distributions are between 0. First, no assumptions are needed about the precise value of expected frequency. In improving on conventional paper, the paper of the invention provides for good fusion of dried toner on the paper at marginal lower temperatures.
