An information processing device in which, when one position on a touch panel is newly pressed in a state in which another position or a plurality of other positions are pressed, the newly pressed position can be reliably specified. A pressed-position-information storing section (70) stores positional information indicating a plurality of positions of a touch panel section (56). Based on a position having a predetermined relationship with the plurality of positions indicated by the positional information that is stored in the pressed-position-information storing section (70), a display limiting section (78) limits a display positions of one or a plurality of position guiding images displayed on a display section (80). A pressed-position acquiring section (74) acquires a pressed position based on the plurality of positions indicated by the positional information stored in the pressed-position information storing section (70) and a position indicated by pressed position information outputted from the touch panel section (56). A processing executing section (76) executes processing based on the pressed position acquired by the pressed-position acquiring section (74).
