Japanese Patent Laid-Open No. 4-27339

  According to Japanese Patent Application Laid-Open No. 4-2733939, the size of the see-through window needs to be at least the same as the size of the liquid crystal display screen, and the position of the see-through window needs to be aligned with the position of the liquid crystal display screen. . However, when the size of the liquid crystal display screen of the mobile phone is currently increasing, the size of the fluoroscopic window is set to the same size as the liquid crystal display screen, and the position of the fluoroscopic window is aligned with the position of the liquid crystal display screen. The arrangement of the fluoroscopic windows is a major design constraint.

  Further, according to Japanese Patent Laid-Open No. Hei 4-273639, it is necessary to always display the entire liquid crystal display screen so that the contents of the liquid crystal display screen can be seen from the see-through window even when the cellular phone is closed. However, as liquid crystal display screens of mobile phones are increasing in size, power consumption increases when all of the liquid crystal display screens are always displayed in both the opened state and the closed state of the mobile phone. In addition, when the mobile phone is closed, it is not always necessary to see the entire display content of the liquid crystal display screen from the perspective window. If all information on the liquid crystal display screen is displayed while the mobile phone is closed, the display Unnecessary information is also displayed, and as a result, there is a problem that more power than necessary is consumed.

  The main object of the present invention is to solve the above-mentioned problems, eliminate the design restrictions due to the arrangement of the fluoroscopic part, and the information processing apparatus of a two-fold type that suppresses power consumption in a closed state It aims at realizing.

An information processing apparatus according to the present invention includes:
A first housing that can be opened and closed, and a second housing, wherein the first housing and the second housing when the first housing and the second housing are closed. An information processing device facing the housing,
In the first casing, a display is provided on a surface facing the second casing when the first casing and the second casing are in a closed state,
In the second casing, when the first casing and the second casing are in a closed state, a part of the display display is seen through from a non-facing surface not facing the first casing. A see-through portion smaller in size than the display that can be provided,
Of the display, a display of a see-through area that can be seen through from the see-through unit when the first housing and the second housing are in a closed state, and an area other than the see-through area It has a display management part which manages a display separately.

  According to the present invention, since the fluoroscopic part having a size smaller than that of the display display is provided, not only the necessary information can be seen through the fluoroscopic part even in the closed state, but there are few design restrictions by the fluoroscopic part, Since the display of the fluoroscopic area and the display of the other areas of the display display are managed separately, only the fluoroscopic area can be displayed in the closed state. As a result, the consumption of the information processing device in the closed state is enabled. Power can be reduced.

Embodiment 1 FIG.
An external view of a two-fold type mobile phone (information processing apparatus) according to this embodiment is shown in FIG. As shown in FIG. 1A, the cellular phone 1 includes a liquid crystal side housing (first housing) 15 in which a large-screen liquid crystal (display display) 17 is disposed and a numeric keypad side housing in which numeric key buttons 20 are disposed. It has a body (second housing) 21.

  The liquid crystal side casing 15 and the numeric keypad side casing 21 can be opened and closed. When the liquid crystal side casing 15 and the numeric keypad side casing 21 are closed, the liquid crystal side casing 15 and the numeric keypad side casing 21 are folded in two and face each other. The liquid crystal side casing 15 and the numeric keypad side casing 21 are provided on the surface facing the numeric keypad side casing 21 when the liquid crystal side casing 15 and the numeric keypad side casing 21 are closed. In addition to the large-screen liquid crystal 17, a receiver 16 and key buttons 18 are disposed on the liquid crystal side housing 15 on the facing surface facing the numeric keypad side housing 21.
