  Next, a state where the panel 10 is mounted on the substrate body 20 will be described.

  FIG. 4 is a front view showing a state in which the panel 10 is mounted on the substrate body 20. FIG. 5 is a side view showing a state in which the panel 10 is mounted on the substrate body 20. In FIG. 5, illustration of electronic components mounted on the printed circuit board 22 is omitted.

  The panel 10 is mounted on the board body 20 by inserting the left and right edge portions of the printed board 22 into the gap H shown in FIG. Further, when the panel 10 is mounted on the substrate body 20, the rectangular portions 46 a of the push-down portions 46 are engaged with the groove portions 23 of the printed circuit board 22. The rectangular portion 46 a engages with the groove portion 23, whereby the panel 10 is positioned in the left-right direction with respect to the printed board 22.

  Further, as described above, each of the RCA terminal hole 56, the pin hole 58, the switch hole 60, the small terminal hole 62, the large terminal hole 64, and the vertically long terminal hole 65 in the panel 10 protrudes forward from the printed circuit board 22. . Therefore, the RCA terminal hole 56, the pin hole 58, the switch hole 60, the small terminal hole 62, the large terminal hole 64, and the vertically long terminal hole 65 are respectively connected to the RCA terminal 26b, the volume terminal pin 28b, the changeover switch 32b, and the small terminal block. The panel 10 is mounted on the substrate body 20 so that each of the portion 30b, the large terminal base portion 30c, and the vertically long terminal portion 30d is inserted.

  Furthermore, as shown in FIG. 2, the dimension J in the left-right direction of the small terminal block 30 b and the small terminal hole 62 is substantially the same. For this reason, when the panel 10 is mounted on the substrate body 20, the small terminal base portion 30 b is fitted into the small terminal hole 62 with no gap left and right. Therefore, the right and left positioning of the panel 10 with respect to the substrate body 20 is performed by fitting the small terminal base portion 30 b and the small terminal hole 62.

  Further, in a state where the panel 10 is mounted on the substrate body 20, the upper end surface 30g of the small terminal base portion 30b abuts on the upper side surface 62a serving as an upper end surface surrounding the small terminal hole 62, and the small terminal base portion 30b is in the upper side surface. It will be in the state pressed by 62a. Therefore, the vertical positioning of the panel 10 with respect to the substrate body 20 is also performed by the fitting of the small terminal base 30b and the small terminal hole 62.

  Further, as shown in FIG. 4, when the panel 10 is mounted on the substrate body 20 that is warped downward in the U-shape, the lower surface 22a of the printed circuit board 22 comes into contact with the upper end surface 46c of the push-up portion 46 and is pushed upward. Then, the upper surface 22b comes into contact with the lower surface 44c of the push-down portion 44 and is pushed down. That is, the area inside the printed circuit board 22 is pushed up by the push-up part 46 and the area outside the printed board 22 is pushed down by the push-down part 44. As a result, a moment in the arrow M direction as shown in FIG. 4 acts on the substrate body 20, and the warpage of the substrate body 20 is corrected.

  In the panel 10 configured as described above, when the edge portion of the printed circuit board 22 is inserted into the gap H formed between the push-down portion 44 and the push-up portion 46, the region inside the printed circuit board 22 becomes the push-up portion. While being pushed up by 46, the area outside the printed circuit board 22 is pushed down by the push-down portion 44. As a result, a moment acts in a direction opposite to the direction in which the substrate body 20 is warped, and the warp of the substrate body 20 is corrected. Therefore, it is possible to prevent occurrence of poor fitting or displacement of the screw hole in the subsequent assembly process. Moreover, the curvature of the board | substrate body 20 can be corrected, without using another member other than the member which comprises an apparatus. For this reason, it becomes possible to correct the curvature of the substrate body 20 without increasing the number of parts and the number of assembly steps.

  In the panel 10, each of the push-down portion 44 and the push-up portion 46 is provided symmetrically with respect to the center of the panel 10. Therefore, an equal pressure can be applied to the left and right ends of the substrate body 20. As a result, the warpage of the substrate body 20 can be corrected more effectively.

  In the panel 10, openings such as an RCA terminal hole 56, a pin hole 58, a switch hole 60, a small terminal hole 62, a large terminal hole 64, and a vertically long terminal hole 65 are formed. Therefore, it is possible to prevent the panel 10 from colliding with an electronic component mounted on the printed board 22 and being unable to be mounted on the board body 20.

  Moreover, in the panel 10, the dimension in the left-right direction of the small terminal hole 62 is substantially the same as the outer dimension in the left-right direction of the small terminal base 30b. For this reason, the small terminal base part 30b is fitted in the small terminal hole 62 in a state where there is no gap on the left and right. Therefore, it is possible to position the panel 10 in the left-right direction with respect to the substrate body 20. As a result, it is possible to mount the panel 10 at a regular position with respect to the substrate body 20, and it is possible to prevent the panel 10 from rattling or being displaced after mounting.

  Further, when the panel 10 is mounted on the substrate body 20, the upper end surface 30g of the small terminal base part 30b comes into contact with the upper side surface 62a of the small terminal hole 62, and the small terminal base part 30b is pressed by the upper side surface 62a. . Therefore, it is possible to position the panel 10 in the vertical direction with respect to the substrate body 20. As a result, it is possible to mount the panel 10 at a regular position with respect to the substrate body 20, and it is possible to prevent the panel 10 from rattling or being displaced after mounting.

  Further, in the panel 10, the push-up part 46 has a rectangular part 46 a, and the rectangular part 46 a engages with the groove part 23 of the printed circuit board 22. For this reason, it is possible to position the panel 10 in the left-right direction with respect to the substrate body 20.

  In the panel 10, the size of the gap H between the push-down portion 44 and the push-up portion 46 is substantially the same as that of the printed board 22. Therefore, both end portions of the substrate body 20 can be held in a horizontal state. As a result, the substrate body 20 can be corrected to a horizontal state.

  Although one embodiment of the present invention has been described above, the present invention is not limited to the above-described embodiment, and can be implemented in various modifications.

  In the above-described embodiment, the push-down portion 44 is provided outside the push-up portion 46, but the left-right positional relationship between the push-up portion 46 and the push-down portion 44 is set so that the push-down portion 44 is provided inside the push-up portion 46. You may make it reverse. As described above, by setting the opposite positional relationship, it is possible to effectively correct the warpage of the substrate body 20 that is warped upward in a U-shape.

  In the above-described embodiment, the push-down portion 44 is provided above the push-up portion 46 with a gap H. However, the push-down portion 44 is positioned below the push-up portion 46. You may make it provide. By setting it as such a structure, it becomes possible to correct | amend the curvature of the board | substrate body 20 greatly warped effectively.

  In the above-described embodiment, the upper surface 62a of the small terminal hole 62 is brought into contact with the upper end surface 30g of the small terminal block 30b to perform positioning in the height direction. The upper end surface of the large terminal hole 64 is brought into contact with the upper end surface of the 30c, and the vertical positioning is performed using other electronic components and holes other than the small terminal base portion 30b and the small terminal hole 62. Also good.

  In the above-described embodiment, the push-up portion 46 has the rectangular portion 46a. However, the push-up portion 46 may not be provided with the rectangular portion 46a.
