It is possible to prevent adverse effects on the electric circuit inside 130.
In addition, since the door opening / closing mechanism and the electronic device that can reliably close the gap S of the opening 133 can be realized with a simpler configuration than the conventional one, it is extremely advantageous for cost reduction and size reduction.
Further, since the front surface 3202 of the lid piece 32 is located on the same plane as the 132 front surfaces around the opening 133 in a state where the open / close door 30 is swung to the lying position, the front surface 132 is exposed with the front surface 132 exposed. It does not impair the aesthetic appearance of the front surface 132, and does not protrude in front of the front surface 132, so that it does not interfere with the user. Further, an excessive force is applied to the cover piece 32 to prevent the cover piece 32 from being damaged. Is done.
Further, since the gap S of the opening 133 is closed by the lid piece 32, the open / close door 30 can be largely laid down to the vicinity of the bottom surface of the housing 130. This is advantageous in improving the operability of various operation buttons and connectors.
