Here, the round hole 1113A of the second fixed piece 1111 and the second female screw portion 1103B of the first fixed piece 1101 overlap in the vertical direction. Therefore, the screw portion (male screw) 1121 of the coupling member 112 can be inserted into the round hole 1113A from above the second fixed piece 1111 and the screw portion 1121 can be screwed into the second female screw portion 1103B of the first fixed piece 1101. (See FIG. 5). When the coupling member 112 is tightened, the first pressing member 110 is pulled upward and the second pressing member 111 is pressed downward. As a result, the rear end portion of the light guide plate 4 can be sandwiched and held between the first pressing piece 1100 of the first pressing member 110 and the second pressing piece 1110 of the second pressing member 111 (FIG. 5). reference).

  Here, the first pressing member 110 has bolts 1104 at both ends in the longitudinal direction (left-right direction). These two bolts 1104 are respectively attached to protrusions 1105 provided at both ends of the first connecting piece 1102 in the longitudinal direction (see FIG. 2). Each protruding piece 1105 is formed integrally with the first connecting piece 1102 so as to protrude forward from the upper end of the first connecting piece 1102.

It is preferable to arrange the second reflecting member 221 between the pressing piece 1110 (see FIG. 5). That is, the light from the rear end portion of the light guide plate 4 is reflected by the first reflection member 220 and the second reflection member 221 and returned into the light guide plate 4 by returning light to be emitted from the rear end portion of the light guide plate 4. Leakage can be suppressed.

  Here, it is preferable that the first reflecting member 220 and the second reflecting member 221 are coupled by the coupling portion 222 and integrally formed as the reflecting sheet 22. As shown in FIG. 5, the coupling portion 222 is formed in a rectangular tube shape whose both ends in the longitudinal direction (left and right direction) are open, and the first reflection member 220 and the second reflection member 221 are forward from the lower portion of the front surface. Configured to protrude. However, on the front surface of the coupling portion 222, a portion sandwiched between the first reflecting member 220 and the second reflecting member 221, that is, a portion facing the light emitting element 20 is open. Such a reflection sheet 22 is preferably formed of, for example, an electrically insulating and flexible material (for example, a synthetic resin such as polyethylene terephthalate). In this case, the first reflecting member 220 and the second reflecting member 221 are preferably configured by depositing aluminum on the surface of a base material formed in a sheet shape with a synthetic resin material or the like. The reflection sheet 22 configured as described above is preferably attached to the second attachment member 11 by sandwiching the coupling portion 222 between the front surface of the first connecting piece 1102 and the light source unit 2 (see FIG. 5). .

  As shown in FIG. 7, the first mounting member 10 is fixed so as to be stacked on the second mounting member 11. First, the first connecting plate 101 is placed on the second fixing piece 1111 of the second pressing member 111, and the fixing screw 104 is inserted downward into the first hole 1010 of the first connecting plate 101. The screw 104 is screwed into the first female thread portion 1103A of the first fixed piece 1101 through the square hole 1113B of the second fixed piece 1111. Therefore, the first connecting plate 101 is coupled to the first fixing piece 1101 of the first pressing member 110 by being screwed with the plurality of screws 104, and the first mounting member 10 is fixed to the second mounting member 11. The However, the instrument body 1 in the present embodiment includes a plurality (two in the illustrated example) of reinforcing members 13 in order to improve the coupling strength between the first mounting member 10 and the second mounting member 11 (FIG. 3C). And FIG. 7).

  As shown in FIG. 8, the reinforcing member 13 includes a flat plate portion 130, a pair of vertical plate portions 131, a pair of horizontal plate portions 132, a first fixing portion 133, and a pair of second fixing portions 134.

The pair of horizontal plate portions 132 are formed so as to protrude from the end along the longitudinal direction of each vertical plate portion 131 in the left-right direction (the direction away from the flat plate portion 130). That is, the reinforcing member 13 is configured to improve the strength in the thickness direction of the flat plate portion 130 by the pair of vertical plate portions 131.

  The first fixing portion 133 is provided on the upper side of the horizontal plate portion 132 on one side (left side in FIG. 8). The first fixing portion 133 is configured by a female screw that protrudes rearward from the back surface of the horizontal plate portion 132. The pair of second fixing portions 134 has a rectangular flat plate shape that is narrower than the horizontal plate portion 132 and is formed so as to protrude downward from the lower end of each horizontal plate portion 132.

  The reinforcing member 13 is arranged on the back surface (rear surface) side of the instrument body 1 so as to straddle the first mounting member 10 and the second mounting member 11. The reinforcing member 13 is fixed to the first mounting member 10 by screwing a fixing screw 105 inserted through a hole provided in the first mounting plate 100 into the first fixing portion 133 (see FIG. 8). Further, the reinforcing member 13 is fixed to the second mounting member 11 by hooking a pair of second fixing portions 134 separately to a pair of hooking portions 1106 provided on the first connecting piece 1102 of the first pressing member 110. . The hook portion 1106 includes a pair of bridge piers 1106A that protrudes rearward from the first connecting piece 1102, and a bridge plate 1106B that spans the pair of bridge piers 1106A. The hooking portion 1106 is configured so that the second fixing portion 134 is inserted and hooked in a space (hole) surrounded by the pair of bridge piers 1106A, the bridge plate 1106B, and the first connecting piece 1102 when viewed from the top and bottom. (See FIG. 8). Note that such a hooking portion 1106 is preferably formed, for example, by punching the first connecting piece 1102.

  Here, the reinforcing member 13 forms a space between the first mounting plate 100 of the first mounting member 10 and the second connecting piece 1112 of the second pressing member 111 by a pair of vertical plate portions 131. In this space, a screw that screws the power supply device 3 to the first mounting plate 100, a screw 212 that screws the light source unit 2 to the second connecting piece 1112, and the like are arranged. That is, the reinforcing member 13 prevents the screws protruding from the rear surfaces of the first mounting member 10 and the second mounting member 11 from interfering with the mounted surface by forming the space.

  Next, the cover member 12 will be described. The cover member 12 includes a main portion 120, a top plate portion 121, a pair of side plate portions 122, a pair of support members 123, and two fixing screws 124 (see FIGS. 2 and 9 to 12). The main part 120 is formed in a long rectangular flat plate shape. The top plate portion 121 is formed in a long rectangular flat plate shape so as to protrude rearward from the upper end of the main portion 120. The pair of side plate portions 122 are formed in a rectangular flat plate shape and are formed so as to be connected to the left and right ends of the main portion 120 and the top plate portion 121, respectively. That is, the cover member 12 is configured in a long rectangular box shape that is opened rearward and downward (see FIG. 2). However, each side plate portion 122 is preferably formed so as to protrude below the lower end of the main portion 120. Further, it is preferable that each side plate portion 122 is formed with a cutout knockout portion 1220, and a power supply cable for feeding wiring is inserted into the hole after the knockout portion 1220 is cut off (see FIG. 10).

  The pair of support members 123 includes a support portion 1230 and a fixing portion 1231 (see FIGS. 9 and 10). The support portion 1230 is formed in a rectangular shape when viewed from the front-rear direction, and a step 1230A is formed from the center to the lower side (see FIG. 10). Further, the support portion 1230 is provided with a large-diameter hole 1232, a small-diameter hole 1233, and a connection hole 1234 (see FIG. 9). The large-diameter hole 1232 is formed in a rectangular shape in which the width dimension in the vertical direction (vertical direction) and the horizontal direction (left-right direction) is larger than the outer diameter of the head 1240 of the fixing screw 124. The small-diameter hole 1233 is formed in a rectangular shape whose vertical width is smaller than the head 1240 of the fixing screw 124 and larger than the male screw portion 1241 of the fixing screw 124. The connection hole 1234 is formed in a trapezoidal shape in which the upper end is connected to the entire lower end of the large diameter hole 1232 and the lower end is connected to about half of the upper end of the small diameter hole 1233. A conductive portion 1235 that is formed in a trapezoidal shape and protrudes downward and rearward is provided at the center of the lower end of the support portion 1230 (see FIGS. 9 and 10).
