Electronic device with AC plug

An electronic device comprising:

• a case;
• an AC plug having blades for connecting said AC plug to a power supply and a holding portion integrally formed on end portions of said blades,
• said AC plug being able to rotate 90 degrees about said case so that said AC plug can be stored in said case;
• an elastic member having two end portions, one end portion being fixed in said holding portion of said AC plug, the other end portion being fixed in said case, wherein when said AC plug is raised up by a rotation of 90 degrees about a rotary shaft, said elastic member extends perpendicular to a central axis of said rotary shaft and is positioned nearer to an opening end surface formed on said case for raising up said AC plug than the central axis;
• a guide groove for guiding said AC plug to rotate 90 degrees, said guide groove having a fixing groove portion for temporarily fixing said AC plug in a position where said AC plug is rotated nearly 90 degrees;
• and
• an engagement member having two end portions for engaging said holding portion of said AC plug with said case such that one end portion of the engagement member is engaged with said guide groove of said AC plug and the other end portion is engaged with a hole portion formed in said case,
• wherein, when said AC plug is raised up from said case, said elastic member is stretched and said engagement member is guided to said fixing groove portion via said guide groove, said AC plug being temporarily fixed in a position where said AC plug is rotated nearly 90 degrees,
• when said AC plug is connected to the power supply so as to make said AC plug completely rotate 90 degrees, said engagement member is guided by said guide groove and thereby the fixed position of said AC plug is released;
• and
• when said AC plug is removed from the power supply, said elastic member contracts and said engagement member is guided by said guide groove, so that said AC plug can be automatically stored again in said case.
