  As shown in FIG. 10, the main body side housing 40 is screwed with a connecting portion 4 b constituting the hinge 4. These connecting parts 4b are connected to the connecting part 4a shown in FIG.

FIG. 15 is a view showing a state in which the keyboard unit 7 and the main unit 8 are connected via the flexible wiring board 14.
One end of the flexible wiring board 14 is connected to the keyboard unit 7 side, and the connection terminal portion at the other end is connected to the connection terminal portion 74 of the main unit 8. The flexible wiring board 14 is bent so that the side surface is substantially U-shaped. The flexible wiring board 14 is drawn from the keyboard unit 7 in the direction in which the keyboard unit 7 slides (the minus direction in the X direction in FIG. 15), is curved, and is bent in the opposite direction (the plus direction in the X direction in FIG. 15). It is routed towards unit 8. When the keyboard unit 7 and the main unit 8 are overlapped and fixed, the flexible wiring board 14 is folded and accommodated in the accommodating portion 75 of the main unit 8. The example in which the flexible wiring board 14 is substantially U-shaped as shown in FIG. 15 is shown. However, the flexible wiring board 14 may be curved so as to have an inverted U shape in the X direction of FIG.

Next, a manufacturing method (assembly method) of the electronic device 1 will be described.
FIG. 16 is a flowchart showing a manufacturing process of the electronic device 1.
The keyboard unit 7 shown in FIG. 5A is prepared (ST1601). For example, as shown in FIG. 5A, the keyboard main body 10 and the keyboard bezel 11 are aligned at predetermined positions and welded and fixed at a plurality of welding locations 19 to prepare the keyboard unit 7.

  The main unit 8 shown in FIG. 10 is prepared (ST1602). For example, as shown in FIG. 10, the wireless run module 41, the modem module 42, the Bluetooth module 43, and the like are built in the first housing 45 and the palm rest 46 is covered. The main body unit 8 is prepared by screwing the connecting portion 4b to the LCD unit fixing portion 44 and screwing the connecting portion 4b as a power switch to the palm rest 46. Note that either the keyboard unit 7 or the main unit 8 may be prepared first.

  In this state, as shown in FIG. 10, the wireless run module 41 and the modem module 42 are exposed from the opening 71, and the Bluetooth module 43 is exposed from the opening 72. The connection terminal portion 74 is exposed from the opening 73.

A combination (fixation) of the keyboard unit 7 and the main unit 8 will be described.
The guide member 39 of the keyboard unit 7 shown in FIG. 5A is fitted into the guide groove 67 of the main unit 8 shown in FIG. 10 (the front side of the keyboard unit 7 is fitted into the main unit 8) (ST1603).

  In a state where the keyboard unit 7 is displaced in the X direction with respect to the main unit 8, the keyboard unit 7 is overlaid on the main unit 8. As a result, the positioning projections 36, 37, 38, 27, 28, 29 and the protrusion 15 of the keyboard unit 7 are inserted into the positioning holes 51, 52, 53, 61, 62, 63 and the insertion hole 49 of the main unit 8, respectively. (ST1604).

17 is a plan view when the keyboard unit 7 is superimposed on the main unit 8, and FIG. 18 is a cross-sectional view taken along the line AA of FIG.
At this time, as shown in FIG. 17, the keyboard unit 7 moves to the main unit 8 at a position shifted in the longitudinal direction (X direction in FIG. 17) of the keyboard unit 7 by a predetermined length w with respect to the main unit 8. fit. For example, as shown in FIG. 18, the positioning protrusion 29 of the keyboard bezel 11 of the keyboard unit 7 is fitted into the positioning hole 63 (the insertion hole 64) of the palm rest 46 of the main unit 8. The protruding portion 15 protruding from the receiving plate 13 of the keyboard unit 7 is fitted into the insertion hole 49 of the palm rest 46 of the main unit 8. Similarly, the positioning protrusion 36 of the keyboard bezel 11 shown in FIG. 5A is fitted into the positioning hole 51 shown in FIG.

  As shown in FIG. 18, for example, the length x1 in the X direction of the engaging portion 32 of the positioning protrusion 29 is 2.85 mm, and the length x2 in the X direction of the protruding portion 15 is 2.87 mm. In this case, the distance x3 between the distal end 80 of the engaging portion 32 and the side surface 81 of the projecting piece 66 facing the projecting wall 31 is, for example, 0.15 mm, and is engaged with the distal end 82 of the flange portion 16 of the projecting portion 15. An interval x4 in the X direction with the end 83 of the protrusion 50 is 0.13 mm.

  With the length w shifted in the X direction shown in FIG. 17, the keyboard unit 7 is slid with respect to the main unit 8 in the longitudinal direction of the keyboard unit 7 (X direction in FIG. 17) (ST1605).

  At this time, the guide member 39 is guided along the longitudinal direction of the keyboard unit 7 while the L-shaped guide member 39 shown in FIG. 5A is engaged with the guide rail 68 shown in FIG. As a result, as shown in FIG. 18, first, the side surface 81 side of the protruding piece 66 enters the hole 35 of the positioning projection 29 (the same applies to the other positioning projections 27 and 36). Subsequently, the flange portion 16 of the protrusion 15 guides the engagement protrusion 50 into the engagement hole 17 of the protrusion 15 with a little delay, and the engagement protrusion 50 enters the engagement hole 17.

  FIG. 19 is a partial cross-sectional view showing a state in which the keyboard unit 7 is fixed to the main unit 8 by this slide.

  As shown in the figure, for example, when the side surface 81 of the protruding piece 66 comes into contact with the protruding wall 31 of the positioning protrusion 29, the sliding of the keyboard unit 7 is stopped. Thus, the protruding piece 66 fits in the hole 35 of the positioning protrusion 29 and the engaging protrusion 50 fits in the engaging hole 17 of the protruding portion 15.

  A plurality of screw holes 26 of the keyboard unit 7 shown in FIG. 5A, a plurality of screw holes 58 of the main unit 8 shown in FIG. 10, and screws (not shown) are fixed (ST1606).

  As described above, the positioning projections 36 and 27 and the protruding portion 15 of the keyboard unit 7 are fixed to the positioning holes 51 and 61 and the insertion hole 49 of the main body unit 8, respectively. Fixed.

  Thus, according to the present embodiment, the guide member 39 of the keyboard unit 7 shown in FIG. 5A is fitted into the guide groove 67 of the main unit 8 shown in FIG. 10 (ST1603), and the main body as shown in FIG. The keyboard unit 7 can be superimposed on the main unit 8 in a state where the keyboard unit 7 is shifted in the X direction by a length w with respect to the unit 8. Thereby, the positioning protrusions 36 and 27 and the protruding portion 15 of the keyboard unit 7 can be inserted into the positioning holes 51 and 61 and the insertion hole 49 of the main unit 8 respectively (ST1604). The keyboard unit 7 is slid in the longitudinal direction of the keyboard unit 7 (X direction in FIG. 17) (ST1605). Accordingly, the guide member 39 can be guided along the longitudinal direction of the keyboard unit 7 while the guide member 39 shown in FIG. 5A is engaged with the guide rail 68 shown in FIG. As a result, as shown in FIG. 18, first, the side surface 81 side of the protruding piece 66 can be inserted into the hole 35 of the positioning protrusion 29 first. Subsequently, the engaging protrusion 50 can be guided into the engaging hole 17 of the protruding portion 15 by the flange 16 of the protruding portion 15 with a slight delay, and the engaging protrusion 50 can be inserted into the engaging hole 17. As a result, the keyboard unit 7 can be fixed to the main unit 8 by the positioning holes 51 and 61 and the plurality of insertion holes 49 shown in FIG.

  That is, the guide member 39, the positioning projections 36, 27, etc. are first positioned near the outer edge of the keyboard unit 7 that is easy for the operator to position, and are slid in this state, so that the operator cannot easily position the keyboard unit 7 inside the keyboard unit 7. The engagement hole 17 of the protrusion 15 can be engaged with the engagement protrusion 50 of the insertion hole 49. Accordingly, when the keyboard unit 7 is attached to the main unit 8, the engagement hole 17 of the protrusion 15 does not engage with the engagement protrusion 50 of the insertion hole 49 in the region near the center of the keyboard unit 7, and the region floats. Can be prevented.

  When removing the keyboard unit 7 from the main unit 8, the keyboard unit 7 is slid with respect to the main unit 8 in the direction opposite to the direction in which the keyboard unit 7 is fixed. Accordingly, the protrusion 15 shown in FIG. 19 is disengaged from the engaging protrusion 50, and the positioning protrusion 29 is disengaged from the protrusion 66 (returns to the state where the keyboard unit 7 and the main unit 8 shown in FIG. 17 are displaced). Thereafter, the positioning protrusions 36 and 27 and the protrusion 15 of the keyboard unit 7 can be removed from the positioning holes 51 and 61 and the insertion hole 49 of the main unit 8.

  As described above, the operation of attaching and detaching the keyboard unit 7 can be simplified. Further, since the keyboard unit 7 can be fixed to the main unit 8 in the regions 22 and 23 along the short sides c and d of the keyboard unit 7 and the inner regions away from the sides a to d of the keyboard unit 7, It is possible to increase the rigidity of the keyboard and improve the keystroke feeling.

  When replacing the keyboard unit 7, the keyboard unit 7 can be removed and replaced without removing the palm rest 46. When replacing the wireless run module 41, the modem module 42, the Bluetooth module 43, and the LCD unit, the keyboard unit 7 is removed and the wireless run module 41 and the modem module 42 are exchanged from the opening 71 or the Bluetooth module 43 is exchanged from the opening 72. Can be exchanged. Accordingly, it is possible to shorten the time for assembling and replacing the keyboard unit 7 and each module.

FIG. 20 is a diagram when the keyboard unit 7 is slid in the direction of the short side of the keyboard unit 7.
As shown in the figure, the keyboard unit 7 is slid in a direction (Y direction in FIG. 20) orthogonal to the longitudinal direction of the keyboard unit 7 (X direction in FIG. 20), and the keyboard unit 7 is fitted into the main unit 8. It is also possible. In this case, when the keyboard unit 7 and the main unit 8 are aligned, the short side c and the short side d of the keyboard unit 7 are separated. Therefore, the keyboard unit 7 bends like the keyboard unit 7a shown in FIG. 20, and the positioning protrusions 27 and the positioning protrusions 36 are difficult to fit into the positioning holes 61 and 51. Further, when the keyboard unit 7 (7a, 7b) is slid in the Y direction, since the short side c and the short side d are separated, the short side c side and the short side d side can be pressed with the same force. It cannot be slid like the keyboard unit 7b shown in FIG. Thus, it takes time to align the keyboard unit 7 and the main unit 8.

  In this embodiment, the keyboard unit 7 and the main unit 8 can be easily aligned by simply inserting the L-shaped guide member 39 into the guide groove 67 and overlapping the keyboard unit 7 on the main unit 8. Therefore, it is possible to prevent the keyboard unit 7 from being bent when the keyboard unit 7 and the main unit 8 are aligned. Further, when the keyboard unit 7 is slid, since the long side a and the long side b are not separated, the keyboard unit 7 and the main unit 8 are fixed without bending the short sides c and d. be able to.

FIG. 21 is a view showing a state in which the protruding portion 15 rides on the palm rest 46.
The flange portion 16 of the projecting portion 15 is directed from the flat portion 30 farthest from the bottom surface 12 of the flat, substantially U-shaped portion of the projecting portion 15 toward the longitudinal direction of the keyboard body 10 (X direction in FIG. 6). Therefore, it is inclined so as to be separated from the bottom surface 12.

  Here, when the keyboard unit 7 and the main unit 8 are overlapped as shown in FIG. 17 and the keyboard unit 7 is slid, the protrusion 15 is inserted into the insertion hole 49 of the palm rest 46 as shown in FIG. Let's consider the case where the user rides on the palm rest 46. In this case, the portion of the keyboard unit 7 corresponding to the protruding portion 15 that rides on the palm rest 46 is raised with respect to the palm rest 46 as compared with the case where the flange portion 16 is not provided. As a result, the operator can easily and reliably know that the engagement protrusion 50 is not fitted in the engagement hole 17 of the protrusion 15.

  The flexible wiring board 14 has one end connected to the keyboard body 10 side and the other end connected to the body unit 8 side. Before the keyboard unit 7 and the body unit 8 are overlapped, as shown in FIG. It is folded so as to have a concave shape in the longitudinal direction. When the keyboard unit 7 and the main unit 8 are fixed, they are folded and accommodated in the accommodating portion 75 of the main unit 8.

  According to such a configuration, for example, when the keyboard unit 7 is slid and attached to the main unit 8 (ST1605), the flexible wiring board 14 can be prevented from being smoothly deformed and added to the flexible wiring board 14. The flexible wiring board 14 can be accommodated in the folded state in the accommodating portion 75. When the keyboard unit 7 slides, the flexible wiring board 14 is sandwiched between the keyboard unit 7 and the main unit 8, and the flexible wiring board 14 can be prevented from being damaged.

  The present invention is not limited to the above embodiment. The present invention can be implemented with various modifications within the scope of its technical idea. The scope of implementation belongs to the technical scope of the present invention.

  In the above embodiment, when the keyboard unit 7 is slid with respect to the main unit 8, first, the side surface 81 of the protruding piece 66 is fitted into the hole 35 of the positioning protrusion 29, as shown in FIG. An example in which the engagement protrusion 50 of the insertion hole 49 is inserted into the 15 engagement holes 17 is shown. However, the present invention is not limited to this. For example, the timing at which the protruding piece 66 is fitted into the hole 35 of the positioning protrusion 29 and the timing at which the engaging protrusion 50 of the insertion hole 49 is inserted into the engaging hole 17 of the protruding portion 15 are almost simultaneously. You may do it.

  In the said embodiment, as shown in FIG.6 and FIG.7, the example in which the protrusion part 15 was provided with the collar part 16 was shown. However, the protruding portion 15 may not include the flange portion 16. Moreover, the example in which the collar part 16 inclines so that it leaves | separates from the flat part 30 toward the longitudinal direction (X direction of FIG.5 and FIG.6) of the keyboard main body 10, and is separated from the bottom face 12 was shown. The inclination angle of the flange 16 is not particularly limited. By increasing the inclination angle, as shown in FIG. 21, when the protruding portion 15 rides on the palm rest 46 without being inserted into the insertion hole 49 of the palm rest 46, the keyboard corresponding to the protruding portion 15 riding on the palm rest 46. The unit 7 part rises higher. Therefore, the operator can more reliably combine and fix the keyboard unit 7 and the main unit 8.

  In the above embodiment, as shown in FIG. 18, the example in which the length x1 of the engaging portion 32 of the positioning protrusion 29 is 2.85 mm and the length x2 of the protruding portion 15 is 2.87 mm is shown. However, these numerical values of the length x1 of the engaging portion 32 and the length x2 of the protruding portion 15 are examples, and are not limited to these.

  In the above embodiment, as shown in FIGS. 17 and 18, the keyboard unit 7 is overlapped with the main unit 8 as shown in FIG. An example of sliding to the left is shown. However, the keyboard unit 7 may be slid to the left with respect to the main unit 8.
