PURPOSE: To improve the handleability of an information processor by providing a display mode changing means which changes the display mode of a specific display element on a display screen based on an external instruction.
CONSTITUTION: The connectors 1 and 2 are provided on the right and left sides of an information processor respectively and own the function to detect the connection of the connector of the mouse side connected to a mouse via a cord. A CPU 7 checks the states of the signal lines 4 and 5 through an I/O port 6 and decides whether the connector of the mouse side is connected to both connectors 1 and 2 or not. Then the CPU 7 changes the display mode on a screen in accordance with the connection state of the connector of the mouse side. When the mouse side connector is connected to the connector 1 set at the right side of the main body of the information processor, the screen is displayed so that the mouse can be easily operated by the right hand and vice versa when the mouse side connector is connected to the left connector 2 respectively. Thus it is possible to change the information processing way through a screen display device and a coordinate input device in response to the connected coordinate input device. Then the handleability of the information processor is improved.
