  The present invention relates to a flat unit structure, particularly an information processing apparatus having a display unit, and a portable computer having a flat unit structure relating to a structure for mounting a flat display unit to a housing in the information processing apparatus.

  Information processing devices are required to be smaller and lighter. In particular, flat display units that also serve as display devices or input devices are required to achieve miniaturization in a structure attached to a housing. Yes.

  2. Description of the Related Art Conventionally, an information processing apparatus (hereinafter referred to as a computer) such as a portable or notebook type word processor or a personal computer has a main body including an input device such as a keyboard, and a display unit configured to be openable and closable with respect to the main body. However, a flat display unit is used as the display unit. This flat display unit is fixed to a casing constituting a lid.

  Conventionally, the flat display unit is fixed to the casing by a structure in which the four flat corners of the rectangular flat display unit are fixed using fixing means such as screws. With such a structure, a space for arranging screws and the like is required between the inner part of the casing constituting the lid and the side surface of the rectangular flat display unit, and the device is small. It was difficult to achieve

  Further, in a notebook type computer, it is required to make it as thin as possible with the display unit closed with respect to the main body. Therefore, it is necessary to make the display portion as thin as possible as well as the main body. For this reason, the space in the thickness direction must be made as small as possible between the flat display unit and the housing. Therefore, it is not preferable to arrange a fixing member such as a bolt between the back surface of the flat display unit or in a space between the upper edge surface or side edge surface of the flat display unit and the wall of the housing. .

  The information processing apparatus is required to be reduced in size and weight, but in particular, a flat display unit that also serves as a display apparatus or an input apparatus is required to be reduced in size when attached to a housing. For this reason, when the flat display unit is attached to the housing, it is desired to minimize the space between the flat display unit and the housing.

  In order to achieve the above-described object, according to the present invention, a rectangular flat display unit is fixed to a housing at three locations of its left and right edges and a central upper edge. Side fixing brackets are fixed to both edge surfaces by screws, the side fixing brackets are fixed to the casing by screws, and the center upper edge of the flat display unit is sandwiched between the back and front surfaces. A planar unit structure is provided which is characterized in that the flat unit structure is fixed to the surface. According to the present invention, the rectangular flat display unit has a structure in which the left and right edges thereof are fixed to the casing by sandwiching the back surface and the front surface through screws on the left and right edges. There is no need for a special space for fixing the flat display unit between the housing and the device, and thus the size of the device can be reduced.

  The center upper edge of the flat display unit is in contact with the sheet whose back is fixed to the housing, and the surface is in contact with the claw portion of the upper center fixing bracket that is fixed to the housing.

The metal fittings 27 are fastened to the side surfaces of the flat display unit 25 as shown in the drawing at two positions separated in the length direction as described above. The pair of left and right metal fittings 27, 27 have the same shape and are fixed to both side surfaces of the flat display unit 25, respectively.

  Thus, the display unit 2 (FIG. 1) is assembled by sandwiching and fixing the flat display unit 25 between the back cover 24 and the front cover 26, and the hinge 30 is connected to the main body 1 (FIG. 1) of the portable computer. The display unit 2 is coupled to the main body unit 1.

  FIG. 24 shows another embodiment modified from the second embodiment of the present invention, in which a hinge without an arm portion and a front cover are shown.

  That is, in the above-described second embodiment, each of the pair of hinges 30 and 30 includes a hinge part 30a that constitutes a hinge for enabling the display part of the computer to be opened and closed with respect to the main body, and the hinge part 30a. The arm portion 30 that extends and has a length corresponding to the side portion of the front cover 26 is integrally formed. However, the hinge 30 ′ shown in FIG. 24 does not have an arm portion extending along the side portion of the front cover 26, and constitutes a hinge having a function for opening and closing the display portion with respect to the main body. It consists only of parts to do.

  Therefore, the hinge 30 ′ shown in FIG. 24 does not require the screw 32 for fixing the arm portion 30 b of the hinge 30 in FIG. 12 to the side portion of the front cover 26. The hinge 30 'is fixed to the main body side (not shown) of the computer on the one hand, and fixed to the front cover 26 or the back cover 24 on the other hand. Although this fixing method is not shown in detail, a fixing hole is provided in the hinge 30 'and a screw hole is provided on the front cover 26 or the back cover 24 side, and a screw (not shown) is provided in this screw hole. It can be fixed by screwing it through the fixing hole of the hinge 30 '.

  Although the embodiments of the present invention have been described with reference to the accompanying drawings, the present invention is not limited to the above-described embodiments, and various forms, modifications, corrections, and the like are within the spirit and scope of the present invention. Is possible.

  As described above, according to the present invention, it is possible to achieve downsizing of the apparatus, and in addition to this, it is possible to reduce the manufacturing cost of the planar unit structure and to reduce the weight. Moreover, in this invention, the distortion concerning a flat display unit can be absorbed and reduced. Therefore, the present invention can be applied to a portable computer having any flat display unit.
