A portable information device is provided to enable a user to input a cursor operation signal without covering a display part, and automatically switch direction of the cursor or pointer operation signal by making a signal switch detect a rotation position of the touch pad. A portable information device includes a body(110), the display part(120) displaying an image in the body, and the touch pad part(180) receiving the cursor or pointer operation signal, and placed to a position separated from the display part to prevent viewing the display part. The touch pad part is rotated to the body to select a first position exposed to a rear direction of the display part and a second position exposed to a front direction of the display part. The signal switch switches the direction of the cursor or pointer operation signal according to selection of the first and second positions. A supporter supports the portable information device in a stand state after the touch pad is rotated to the second position. A button part(160,170) inputs click or scrolling information, and is installed to the position separated from the display and touch pad part.
