Portable electronic game, connectable to video game controller, where the display inverts when connected

摘要

A portable electric device is capable of displaying data in display orientations which are vertically different depending on an apparatus or unit to which the portable electric device is connected. The portable electric device has a program memory (41a) for storing a program, a microcomputer (41) for controlling the execution of the program, a display unit (130) for displaying information based on the program which is executed, a manual control pad (120) for controlling the program, and a connection detecting unit (41) for detecting a connection to a master unit, a power supply adapter unit (500), etc., and a display control unit (41) for setting the orientation of information displayed by the display unit (130) to an inverted display orientation ( beta ) when a connection to the entertainment apparatus (1) is detected, and thereafter inverting the information displayed in the inverted orientation ( beta ) and displaying the inverted information in a normal orientation (a) when a manual control input is entered via the manual control pad (120).
