  Hereinafter, a method for fixing the protective cover 10 to the first housing 1 will be described.

  FIG. 8 is a perspective view showing a state immediately before the protective cover 10 is fixed to the first housing 1. FIGS. 9A, 10 </ b> A, and 11 are plan views illustrating a process of attaching the protective cover 10 to the first housing 1. 9B and 10B are enlarged plan views of the first positioning hole 14. 9A to 11 are plan views of the protective cover 10 as viewed from the first outer surface 11f side. 9A, 10 </ b> A, and 11, the grip belt 17 and the raised portions 18 a to 18 d are not illustrated in order to clearly illustrate the positional relationship between the first housing 1 and the protective cover 10. Further, the first projecting member 14 and the second projecting member 15 shown in FIGS. 9A, 10A, and 11 are given dot hatching to clearly show their positions.

  First, as shown in FIG. 8, from the state where the protective cover 10 and the notebook computer are separated from each other, the lower surface 1b of the first housing 1 is opposed to the first inner surface portion 11b of the protective cover 10, and the hinge portion 3 is The notebook computer is placed on the first inner surface portion 11b of the protective cover 10 in a posture that is positioned in the vicinity of the first boundary portion 11m. 8 is intended to be placed on the first inner surface portion 11b of the protective cover 10 in a closed state. For example, the first personal computer of the protective cover 10 in an opened state as shown in FIG. It can also be placed on the inner surface portion 11b.

  When placing the notebook computer on the first inner surface portion 11 b of the protective cover 10, the first projecting member 14 is inserted into the circular hole 51 a of the first positioning hole 51 as indicated by the arrow D, and the arrow E is indicated. In this manner, the second protruding member 15 is inserted into the circular hole 52 a of the second positioning hole 52. 9A and 9B, the laptop computer is placed on the first inner surface portion 11 b of the protective cover 10, and the first protrusion member 14 is inserted into the circular hole 51 a of the first positioning hole 51, and the second protrusion The state in which the member 15 is inserted into the circular hole 52a of the second positioning hole 52 is shown. In the state shown in FIG. 9A, the hole 16 of the protective cover 10 and the screw hole 53 of the first housing 1 are displaced from each other.

  Next, the notebook computer is slid in the direction indicated by the arrow G along the first inner surface portion 11b of the protective cover 10 from the position shown in FIG. 9A. When the notebook computer slides in the direction indicated by the arrow G, the relative positional relationship between the first positioning hole 51 and the first protruding member 14 changes from the positional relationship shown in FIG. 9B to the positional relationship shown in FIG. 10B. That is, from the state where the shaft portion 14b of the first projecting member 14 is positioned in the circular hole 51a of the first positioning hole 51 as shown in FIG. 9B, the end portion of the elongated hole 51b as shown in FIG. 10B. The first positioning hole 51 is displaced so as to be in contact with 51c. Similarly, the second projecting member 15 has the shaft portion 15b positioned in the circular hole 52a of the second positioning hole 52 to be in contact with the end portion of the elongated hole 52b. The positioning hole 52 is displaced.

Here, the width dimension R1 of the tip portion 14a of the first projecting member 14 and the width dimension R12 of the elongated hole 51b are:
R12 <R1
Have the relationship. Therefore, the positional relationship between the first projecting member 14 and the first positioning hole 51 is the positional relationship shown in FIG. 10B, that is, the positional relationship in which the distal end portion 14 a of the first projecting member 14 and the elongated hole 51 b overlap. Similarly, when the positional relationship between the second projecting member 15 and the second positioning hole 52 becomes the positional relationship shown in FIG. 10A, the first housing 1 has the axial direction of the shaft portion 14 b of the first projecting member 14. The displacement to is restricted.

  When the notebook computer slides to the position shown in FIG. 10A on the first inner surface portion 11b of the protective cover 10, the first projecting member 14 comes into contact with the end portion 51c of the long hole 51b (the end portion farthest from the circular hole 51a). The second projecting member 15 contacts the end of the long hole 52b (the end farthest from the circular hole 52a). Thereby, the notebook computer is restricted from sliding in the direction indicated by the arrow G.

  Further, the side portions 51d and 51e facing each other in the elongated hole 51b and the shaft portion 14b are in contact with each other or close to each other with a slight gap therebetween, whereby the shaft portion 14b is positioned in the H-axis direction shown in FIG. 10B. Is regulated. As a result, the position of the notebook personal computer in the H-axis direction is restricted with respect to the protective cover 10, and the notebook personal computer can be fixed to the protective cover 10 in a state where mechanical backlash with respect to the protective cover 10 is minimized.

  In the state shown in FIG. 10A, the hole 16 and the screw hole 53 overlap so that their centers coincide.

  Next, as shown in FIG. 11, the screw 54 is inserted into the hole 16 from the first outer surface portion 11 f side of the protective cover 10 and screwed into the screw hole 53. Since the outer diameter of the distal end portion of the screw 54 is larger than the inner diameter of the hole portion 16 formed in the protective cover 10, the distal end portion of the screw 54 and the first housing are screwed into the screw hole 53. 1 can sandwich the protective cover 10. Therefore, the protective cover 10 can be fixed to the first housing 1.

  As described above, the notebook computer can be fixed to the first inner surface portion 11 b of the protective cover 10.

  When the protective cover 10 is detached from the notebook computer, first, in FIG. 11, the screw 54 is detached from the screw hole 53 (see FIG. 10A) and the hole portion 16 to obtain the state shown in FIG. 10A. In the state shown in FIG. 10A, the first protruding member 14 is engaged with the first positioning hole 51, and the second protruding member 15 is engaged with the second positioning hole 52.

  Next, the notebook computer is slid in the direction shown by the arrow R from the position shown in FIG. 10A and displaced to the position shown in FIG. 9A. Specifically, as shown in FIG. 9B, the notebook computer is slid to a position where the tip end portion 14a of the first projecting member 14 and the circular hole 14a of the first positioning hole 51 overlap (not shown). The same applies to the second projecting member 15 and the second positioning hole 52).
