DETAILED DESCRIPTION To the end, according to a first aspect of the present invention, there is provided a portable information terminal unit comprising a first and a second casing, a hinge means coupling the first and second casings with each other so that the first and second casing are relatively rotatable with respect to each other, an opening piercing through the first casing, a see-through first liquid crystal display part fitted in the opening, and a manipulation part incorporated in the second casing, a means for detecting an opening of the first and second casing, a control means for reversing a display on the see-through first liquid crystal display part in response to a detection by the detecting means.
According to the second aspect of the present invention, there is provided a portable information terminal unit comprising a first and second casings, a hinge means for coupling the first and second casing with each other so that the first and second casing are relatively rotatable with respect to each other, an opening piercing through the first casing, a see-through first liquid crystal display part fitted in the opening, and a second liquid crystal display part provided in the second casing, a means for detecting an opening of the first and second casings, and a control means for reversing a display on the see-through first liquid crystal display part in response to a detection by the detecting means.
According to a specific embodiment of the second aspect of the present invention, the first and second casing are set in such a relationship that the see-through first liquid crystal display part is superposed with the second liquid crystal display part at least in part of the latter when the first and second casing are closed being mated with each other.
With this arrangement, even though the first and second casing are closed being superposed with each other, information displayed on the see-through first liquid crystal part can be observed from the outside.
Further, information displayed on the second liquid crystal display part can be observed through the see-through first liquid crystal display part
