ABSTRACT:
A portable information terminal is provided. The terminal includes a touch screen panel having an activation area and an activating unit. The activation unit activates the portable information terminal when the terminal is turned off and an activating position on the activation area is pressed for a predetermined time. The activating unit contains a press position sensor, a press timer, and a controller. The press position sensor senses if a panel position on touch screen panel is pressed and determines a location of the panel position on the touch screen panel to generate corresponding press position data. The press timer determines if the panel position is pressed for at least a predetermined time to generate corresponding press time data. The controller inputs the press position data and the press time data, determines if the panel position is located within the activation area based on the press position data, and controls power supplied to various components of the portable information terminal such that the power is supplied when the panel position is located within the activation area and when the activation area is pressed for at least the predetermined time.
