Further, since the rear part of the main body 2 is lifted from the desk top surface by the pair of leg portions 22, even if the display unit 3 is opened more than 90 degrees with respect to the main body 2, the rear part of the display unit 3 touches the desk top surface. Smooth contact is possible without touching.

  Then, as shown in FIG. 13, the display unit 3 is expanded with respect to the main body 2 until the LCD 31 of the display unit 3 is easy to see for the user.

  Here, FIG. 15 is a perspective view showing a state in which a display unit of a computer which is a conventional information processing apparatus is opened with respect to the main body, and FIG. 16 is a side view thereof. In the computer 500, the display unit 520 with respect to the main body 510 includes a convex portion 531 provided in a substantially central portion of the main body 510 and a concave portion 532 provided in a substantially central portion of the display portion 520 and meshing with the convex portion 531. The hinge 530 is configured to be freely opened and closed.

  FIG. 17 is a perspective view showing a state in which the display unit of another computer which is a conventional information processing apparatus is opened with respect to the main body, and FIG. 18 is a side view thereof.

  In the computer 600, a display unit 620 is attached to a main body 610 through a pair of hinges 630 so as to be freely opened and closed. The battery pack 640 is detachably disposed between the pair of hinges 630.

  When using these computers 500 and 600 on the desk surface, the user moves his / her line of sight between the keyboards 511 and 611 on the main bodies 510 and 610 and the screens 521 and 621 on the display units 520 and 620. become. Here, in both computers 500 and 600, the widths of the main bodies 510 and 610 and the display units 520 and 620 are a, the widths of the screens 521 and 621 are b, the widths of the keyboards 511 and 611 are c, and the lower portions of the screens 521 and 621 are lower. Consider a case in which the distance between the areas of the display portions 520 and 620 that can accommodate and arrange the substrates is the same as d. The distance between the central axis 630a of the hinge 630 and the lower end 621a of the screen 621 is d2.

  Then, the minimum movement angle α1, α2 of the user's line of sight, that is, the angle formed between the upper end 511a, 611a of the keyboard 511, 611 and the viewpoint E and the lower end 521a, 621a of the screen 521, 621, and the maximum movement of the user's line of sight. The angles β1, β2, that is, the angles formed between the lower ends 511b, 611b of the keyboards 511, 611 and the viewpoint E and the upper ends 521b, 621b of the screens 521, 621 are relative positional relationships between the central axes 530a, 630a of the hinges 530, 630. It is understood that it is greatly influenced by.

  That is, since the central axes 530a and 630a of the hinges 530 and 630 of the computers 500 and 600 are arranged on the upper side outside the main bodies 510 and 610 and parallel to the extended lines of the screens 521 and 621, the screen 521 and 621 are arranged at positions separated by a distance d of a region where a substrate or the like can be stored and arranged, and the minimum movement angles α1 and α2 and the maximum movement angles β1 and β2 of the user's line of sight are both increased. End up. For this reason, there is a problem that the user tends to accumulate fatigue especially in long-time use, and the working efficiency is deteriorated.

  On the other hand, FIG. 19 shows a display unit in which the width of the main body 2 and the display unit 3 of the computer 100 of this embodiment is a, the width of the LCD 31 is b, the width of the keyboard 11 is c, and a substrate below the LCD 31 can be accommodated. FIG. 32 is a side view corresponding to the conventional computers 500 and 600 shown in FIG. 29 and FIG. At this time, the display unit 3 is disposed so as to be perpendicular to the projecting portions 101 and 111 protruding in the radial direction from the central axes 1a and 1b of the hinges 1A and 1B disposed inside the main body 2. 3 wraps around the back of the main body 2, and the LCD 31 approaches the keyboard 11. That is, the distance d0 between the central axes 1a and 1b of the hinges 1A and 1B of the computer 100 of the present embodiment and the lower end 31a of the LCD 31 is greater than the distance d of the area of the display unit 3 that can accommodate and dispose the lower substrate of the LCD 31. Becomes smaller.

  Therefore, the minimum movement angle α0 of the user's line of sight in the computer 100 of the present embodiment, that is, the angle formed between the upper end 11a of the keyboard 11 and the viewpoint E and the lower end 31a of the LCD 31, and the maximum movement angle β0 of the user's line of sight, The angle formed between the lower end 11b of the keyboard 11 and the viewpoint E and the upper end 31b of the LCD 31 is smaller than the minimum movement angles α1 and α2 and the maximum movement angles β1 and β2 of the user's line of sight in the conventional computers 500 and 600. For this reason, the movement distance of the eyes at the time of use becomes short, and it becomes difficult for the user to get tired even when used for a long time, so that the working efficiency can be improved.

  Furthermore, as shown in FIG. 14, when the display unit 3 is expanded with respect to the main body 2, the display unit 3 and the main body 2 can be made substantially horizontal. At this time, since the protector 42 slightly protruding from the rear part of the display unit 3 protects the rear part of the display unit 3, damage due to rubbing with the desk surface can be prevented.

  The computer 100 configured as described above further provides the following effects. FIG. 20 is a perspective view showing a state in which a display unit of a computer which is a conventional information processing apparatus is opened with respect to the main body, and FIG. 21 is a side view thereof. In the computer 400, a display unit 420 is attached to a main body 410 through a pair of hinges 430 so as to be freely opened and closed. The battery pack 440 is detachably disposed between the pair of hinges 430.

  The computer 400 is placed with a gap between the leg portion 411 provided on the lower surface of the front portion of the main body 410 and the leg portion 441 provided on the lower surface of the battery pack 440 with a desk surface or the like. The cooling air for the built-in electronic component is taken in from an air intake hole (not shown) provided on the lower surface of the main body 410.

  When the display unit 420 of the conventional computer 400 is opened and sold with respect to the main body 410, the battery pack 440 is usually removed to prevent the battery pack 440 from being stolen. However, since the lower end of the display unit 420 opens and closes along the outer periphery of the hinge 430, a hole 440a through which the battery pack 440 is removed is formed between the main body 410 and the display unit 420 as shown in FIG. There was a drawback that it became worse.
