Thereafter, the length of the flexible substrate 30 between the front surface 12 of the main body 10 and the back surface 22 of the display unit 20 is adjusted using the holder 28, and the holder 28 is fixed to the back surface 22 of the display unit 20. As shown in FIG. 14, the display unit 20 is made independent. The cover part 60 is fitted into the notch part 48. The frame 40 is screwed to the main body 10. Thus, the attachment of the display unit 20 is completed.

  Next, the step of adjusting the length of the flexible substrate 30 will be described in detail. 15A is a plan view showing the holder 28 and the back surface 22 of the display unit 20, and FIG. 15B is a cross-sectional view of the back surface 22 of the display unit 20 and the holder 28 before the length of the flexible substrate 30 is adjusted. FIG. 15C is a cross-sectional view when adjusting the length. In FIG. 15A, the flexible substrate 30 is omitted.

  As shown in FIG. 15A, the holder 28 is slid in the direction of the arrow on the back surface 22 of the display unit 20. The movable range of the holder 28 is a range in which the protrusion 29 of the holder 28 can move within the opening 23 provided on the back surface 22 of the display unit 20.

  As shown in FIG. 15B, the flexible substrate 30 is inserted into the opening 21 provided on the back surface 22 of the display unit 20 through the opening 27 of the holder 28.

  As shown in FIG. 15C, when the holder 28 is slid, the flexible substrate 30 is bent by the holder 28 and the opening 21. Thereby, the length of the flexible substrate 30 is adjusted. Specifically, the length of the flexible substrate 30 is shortened by sliding the holder 28 in the direction of the arrow in FIG. In the state of FIG. 15C, the holder 28 is fixed to the back surface 22 of the display unit 20 with screws (see FIG. 5A).

  Next, an example in which the length of the flexible substrate 30 is adjusted and a comparative example in which the length is not adjusted will be described using specific examples. FIG. 16A is a side view of an electronic device according to a comparative example, and FIG. 16B is a side view of the electronic device according to the example. In both the comparative example and the example, the total length of the flexible substrate is 98 mm. Further, the frame 40 and the holder 28 are shown in a transparent manner.

  As shown in FIG. 16A, the display unit 20 is connected to the slider 50 and tilted with respect to the front surface 12 of the main body unit 10. The flexible substrate 30 is connected between the front surface 12 of the main body 10 and the back surface 22 of the display unit 20. In the comparative example, the length L3 of the flexible substrate 30 between the lowest point of the flexible substrate 30 and the front surface 12 of the main body 10 is 20.3 mm, and the lowest point of the flexible substrate 30 and the back surface of the display unit 20 22, the length L4 of the flexible substrate 30 is 58.4 mm. The height H between the lowest point and the slider 50 is 5.5 mm, and the lowest point is located 5.5 mm below the slider 50. For this reason, as indicated by a dotted line in the figure, when the display unit 20 is tilted, the flexible substrate 30 and the slider 50 come into contact with each other, and noise is generated.

  As shown in FIG. 16B, the length of the flexible substrate 30 is adjusted using the holder 28 (see FIGS. 15A and 15C). Therefore, L3 is 11.5 mm and L4 is 57.2 mm. That is, the length of the flexible substrate 30 between the front surface 12 of the main body 10 and the back surface 22 of the display unit 20 is shorter than that of the comparative example. The height H between the lowest point of the flexible substrate 30 and the slider 50 is 2.4 mm, and the lowest point is located above the slider 59. For this reason, even when the display unit 20 is tilted, the flexible substrate 30 and the slider 50 do not come into contact with each other. That is, according to the embodiment, it is possible to suppress the generation of noise due to the flexible substrate 30 being rubbed.

  The step of adjusting the length of the flexible substrate 30 is performed after the flexible substrate 30 is connected to the front surface 12 of the main body 10 and the back surface 22 of the display unit 20. That is, in the electronic device in which the lower portion 44 of the frame 40 protrudes from the upper portion 42, the electronic device can be easily manufactured by making the flexible substrate 30 longer. Furthermore, since the length of the flexible substrate 30 is adjusted thereafter, the flexible substrate 30 can be prevented from rubbing. Further, as described with reference to FIG. 15C, the holder 28 is fixed to the back surface 22 of the display unit 20 after the length of the flexible substrate 30 is adjusted, so that the state in which the length of the flexible substrate 30 is adjusted is maintained. Is done.

  In FIG. 9B, the display unit 20 is disposed below the frame 40 in order to connect the flexible substrate 30 to the connector 14 at the front upper side of the front surface 12 of the main body unit 10, for the hands and jigs of the assembler. This is to secure a space for. In particular, in an electronic device in which the lower portion of the display unit 20 is tilted away from the main body 10 as shown in FIG. The operation unit is arranged. Therefore, the connector 14 is disposed in the lower region of the front surface 12. In order to secure a space for the assembler's hands and jigs, the display unit 20 is disposed below the frame 40, and the flexible board 30 is disposed. It is preferable to connect to the main body 10.

  As shown in FIG. 4B, the holder 28 has two holes for screwing. However, the hole 28 is not limited to two, and the holder 28 can be firmly fixed by providing more holes. Is possible. The frame 40 may not be provided with the notch 48. However, it is preferable that the notch 48 is provided because the connecting process is simplified by the notch 48 even when the flexible substrate 30 is long. As shown in FIG. 14, the entire electronic device 20 is housed in the frame 40, but at least a part of the electronic device 20 may be housed in the frame 40. The operation of the electronic device 20 is not limited to tilting, and may be displaced with respect to the main body unit 10.
