Abstract: It is intended to provide a method for selecting a writing sheet for a touch panel pen that can accurately select a writing sheet with which the generation of unpleasant sounds during writing is suppressed. According to the method for selecting a writing sheet for a touch panel pen, a sheet satisfying condition 1-1 and condition 1-2 described below is selected as a writing sheet for a touch panel pen. <condition 1-1> Sound generated when writing is performed under predetermined conditions using a touch panel pen on the surface of a writing sheet for a touch panel pen is recorded. The sound pressure (dB/Hz) is calculated for each 1 Hz from the recorded sound by means of fast Fourier transform. The values of the dB/Hz at frequencies from 1 Hz to 20,000 Hz are normalized to have a maximum value of 100 and a minimum value of 0, and the normalized values of dB/Hz are adopted as rated sound pressures P.

Abstract: A printer with a sorter unit allows printed recording sheets to be sorted to a single tray selected from a plurality of trays by a recording sheet guide mechanism that pivots around a shaft. Thus, the printer can sort the printed sheets by page, by user, or discharge the printed sheets paginated or with the printed side facing upward. The sorter trays includes a first detection lever that is rotated by the weight of recording sheets and a second detection lever that rotates in association with the first detection lever. A lever detector is provided on the sorter guide to detect the movement of the second detection lever. The sorter or guide is also provided with a sheet detection lever to detect a jam in the sorter guide.

Abstract: A printer with a sorter unit allows printed recording sheets to be sorted to a single tray selected from a plurality of trays by a recording sheet guide mechanism that pivots around a shaft. Thus, the printer can sort the printed sheets by page, by user, or discharge the printed sheets paginated or with the printed side facing upward. The recording sheet guide mechanism is constructed to pivot around the shaft so that only a single drive unit is employed to select a tray for sorting. Thus, the printer has a simple and small structure. The printer has a recording sheet discharge outlet with discharge rollers for discharging a recording sheet that has been printed by the electrophotographic process.

Abstract: An electrophotographic recording apparatus comprising these units which are arranged vertically: a sheet feeder for feeding a sheet of recording paper to a sheet feed inlet; an image forming unit for forming a printing image onto a photosensitive drum based on printing data and transferring the printing image onto the sheet; and a fixing unit for fixing the transferred image on the sheet. The apparatus further comprises a sheet switching guide mechanism by which the head end of the sheet is switched to both upper and lower directions. When the sheet switching guide mechanism is set to the upper direction, the printed sheet is forwarded by a sheet guide member to thereby pass through the printing path the sheet has already been through with the rear side of the sheet being the front, and the printing data is written from the last line during this process.
