It is achieved by

[0009]

According to the information processing apparatus of the present invention having the above-described structure, a stacking method, which is an assembling method with good mass productivity in a mass production line, can be performed, and at the same time, a state in which only the opening / closing lid part without the upper case of the main body is assembled. For example, it is possible to assemble the unit (with hinge spring and harness) and the unit with the case on the case body side to attach parts around the rotation axis of the information processing device and connect the liquid crystal harness. Can realize a much better assembly structure than the conventional structure.

Further, since the upper and lower cases can be easily removed by removing the case cover, it is easy to replace the internal components of the opening / closing lid, the liquid crystal harness connecting the case body side and the opening / closing lid side, and the hinge spring. You can do it.

Further, even in the unit state in which the opening / closing lid and the upper case of the main body are assembled, the unit can be removed from the case main body side and the parts built in the case main body side can be replaced.

Therefore, it is possible to develop a portable information processing apparatus which is excellent in both maintainability of unit assembly in parts replacement and stacking type mass production assembly.

It should be noted that it seems that the number of parts is increased by adopting a structure in which the windows are covered with a case cover. However, even in the conventional structure, the stacking system is different from the case where the window through the liquid crystal harness is closed from the upper case of the main body. Since parts are required and a case cover is attached to the unit assembling method, the number of parts does not increase.
