The pin 82P may have a hollow or solid cylinder shape. Either the first pin 82Pa or the second pin 82Pb may also be omitted, and in this case, the groove in the first substrate P1 corresponding to the omitted pin may also be omitted. In addition to the first pin 82Pa and the second pin 82Pb, pins 82P may also be additionally formed in other plural recesses 80Rb, 80Rd, 80Re. In this case, corresponding to the additional pins, grooves may be additionally formed in the first substrate P1.

[0093] The protrusion 82S may protrude from the first recess 80Ra in the same direction as the first pin 82Pa, and the protrusion 82S may be spaced from the first pin 82Pa in the length direction of the first groove 14a. The distance between the first pin 82Pa and the protrusion 82S may correspond to the length of the first groove 14a. The first surface 82S1 of the protrusion 82S facing the first pin 82Pa may be inclined at an obtuse angle with respect to the bottom member 80Raz of the first recess 80Ra. The second surface 82S2 of the protrusion 82S opposite to the first surface 82S1 may intersect (be perpendicular to) the bottom member 80Raz. The protrusion 82S may have a pyramid shape with a part cut out, and the second surface 82S2 may be formed on the cut-out part. For example, the protrusion 82S may be formed by stamping from the front of the bottom member 80Raz toward the rear, and corresponding to the stamping process, a hole 80Rh larger than the protrusion 82S may be formed in the bottom member 80Raz. The protrusion 82S may be formed in other plural recesses 80Rb, 80Rc, 80Rd, 80Re instead of the first recess 80Ra, or may also be formed in other plural recesses 80Rb, 80Rc, 80Rd, 80Re in addition to the first recess 80Ra. In this case, grooves corresponding to the protrusion 82S as a substitute or addition may be additionally formed in the first substrate P1.

[0094] Refer to Figure 18 and Figure 14 , the first substrate P1 may be placed on the plural recesses 80R of the first part 80a of the frame 80. The front surface of the first substrate P1 may be placed on the back surface of the bottom members of the plural recesses 80R. The first substrate P1 placed on the plural recesses 80R may be configured to be parallel to the first part 80a of the frame 80.

The first pin 82Pa can be inserted into the first groove 14a, and the second pin 82Pb can be inserted into the second groove 14b.

[0096] The user can move the first substrate P1 so that the first clamping piece approaches the first contact portion 82a, the second clamping piece 15b approaches the second contact portion 82b, and the third clamping piece 15c approaches the third contact portion 82c. For example, the user can push the first substrate P1 placed on the plurality of recessed portions 80R to the left.

[0097] Refer to Figure 19 and Figure 20 As corresponding to the action of the user pushing the first substrate P1 to the left, the first clamping piece 15a fixed to the first substrate P1 can approach the first contact portion 82a. At this time, the first pin 82Pa can perform relative movement in the first groove 14a and can guide the movement of the first substrate P1.

[0098] Thereby, the second member 822 of the first contact portion 82a can be inserted into the second part 132 of the first hole 13a and the groove 151g of the first clamping piece 15a, and the front surface of the horizontal portion 821b of the first member 821 of the first contact portion 82a can be located on the back surface of the main body 151 of the first clamping piece 15a.

[0099] Also, the first substrate P1 can be slightly lifted as it moves along the first surface 82S1 of the protrusion 82S, and then descends again onto the first recessed portion 80Ra as the protrusion 82S is inserted into the first groove 14a. One end of the first groove 14a can be caught by the first pin 82Pa, and the first pin 82Pa can limit the movement of the first substrate P1 to the left. The other end of the first groove 14a can be caught by the second surface 82S2 of the protrusion 82S, and the protrusion 82S can limit the movement of the first substrate P1 to the right.

[0100] Refer to Figure 21 and Figure 22 As corresponding to the action of the user pushing the first substrate P1 to the left, the second clamping piece 15b fixed to the first substrate P1 can approach the second contact portion 82b.

[0101] Thereby, the second member 822 of the second contact portion 82b can be inserted into the second part 132 of the second hole 13b and the groove 151g of the second clamping piece 15b, and the front surface of the horizontal portion 821b of the first member 821 of the second contact portion 82b can be located on the back surface of the main body 151 of the second clamping piece 15b.

[0102] Reference Figure 23 and Figure 24 In correspondence with the user's action of pushing the first substrate P1 to the left, the third clip 15c fixed to the first substrate P1 can approach the third contact portion 82c. At this time, the second pin 82Pb can move relatively in the second groove 14b and can guide the movement of the first substrate P1.

[0103] Thereby, the second member 822 of the third contact portion 82c can be inserted into the second portion 132 of the third hole 13c and the groove 151g of the third clip 15c, and the front surface of the horizontal portion 821b of the first member 821 of the third contact portion 82c can be located on the back surface of the main body 151 of the third clip 15c.

[0104] Furthermore, one end of the second groove 14b can be caught by the second pin 82Pb, and the second pin 82Pb can restrict the movement of the first substrate P1 to the left.

[0105] Reference Figure 25 and Figure 26 One ends 152a, 153a of the plurality of arm portions 152, 153 of the plurality of clips 15a, 15b, 15c can form a step that rises from the back surface of the plurality of main bodies 151. The horizontal portion 821b can be fixed to the recessed portion 80R under the action of the inclined portion 821a and the second member 822, and the horizontal portion 821b can press one ends 152a, 153a of the plurality of arm portions 152, 153 forward. Thereby, the contact between the contact portion 82 and the clip 15 can be continuously maintained stably, and the first substrate P1 can be electrically grounded to the frame 80 through the clip 15 and the contact portion 82.

[0106] Under the action of the plurality of pins 82Pa, 82Pb, protrusions 82S inserted into the plurality of grooves 14a, 14b and the plurality of contact portions 82a, 82b, 82c inserted into the plurality of holes 13a, 13b, 13c, the movement of the first substrate P1 in the horizontal direction (i.e., the left - right direction) and the vertical direction (i.e., the up - down direction) can be restricted. Also, the plurality of horizontal portions 821b of the plurality of contact portions 82a, 82b, 82c can press the plurality of clips 15a, 15b, 15c fixed to the first substrate P1 forward, and the plurality of contact portions 82a, 82b, 82c can restrict the movement of the first substrate P1 backward.

[0107] Thereby, the first substrate P1 can be detachably coupled to the first portion 80a of the frame 80. That is, the first substrate P1 can be coupled to the first portion 80a without fastening members.

[0108] In addition, a plurality of portions of the first substrate P1 adjacent to the first to third corner portions C11, C12, C13 may be combined with the first to third recessed portions 80Ra, 80Rb, 80Rc, and a portion of the first substrate P1 adjacent to the fourth corner portion C14 may be combined with the fourth recessed portion 80Rd and the fifth recessed portion 80Re by fastening members F1, F2 such as screws.

[0109] Refer to Figure 27 , a plurality of clips 15d, 15e may also be fixed to a portion of the first substrate P1 adjacent to the fourth corner portion C14. In this case, a plurality of contact portions 82d, 82e are formed in the fourth recessed portion 80Rd and the fifth recessed portion 80Re and combined with the plurality of clips 15d, 15e. Thus, the first substrate P1 can be more stably combined with the first portion 80a of the frame 80.

[0110] Refer to Figure 28 , a hole 82h may be formed in the bottom member 80Raz of the first recessed portion 80Ra and / or the inclined portion 821a of the first contact portion 82a.

The hole 82h may be located at the boundary between the bottom member 80Raz and the inclined portion 821a. The hole 82h may be a circular (elliptical) hole. Thus, the mold stability can be improved.

[0115] The groove 34 can be formed to penetrate the second substrate P3, and the groove 34 can be spaced apart from the hole 33.
