Abstract: A display device equipped with a touch panel may include a device chassis provided with an opening section, a display panel having a display surface disposed accessible through the opening section, a touch panel disposed on the display surface of the display panel and capable at least of selecting a function displayed on the display surface in response to a pressing operation on the touch panel, and a surface sheet for covering the touch panel on the opposite side to the display panel, and closing the opening section to form a substantially the same surface with the device chassis, wherein a reinforcing area for improving resistivity against pressing force applied from the outside may be provided in a predetermined range of the surface sheet.

Abstract: An operation to skip plural pieces of music continuously is performed in a reproduction order or a reversed reproduction order circularly. When a piece of music to be reproduced first is selected, identification sound deciding that the piece to be reproduced first is selected is output. Hearing the identification sound allows it to be decided that the piece to be reproduced first is selected without using any display. When the piece to be reproduced first is selected, the skip is stopped to start its reproduction, thereby enable its selection to be surely decided. Every time the piece of music to be reproduced second or later is selected in a continuous skipping operation, the switchover sound different from the identification sound is output.
