FIG. 7 shows the assembly relationship between the first to third positioning holes 92a to 94a and the first to third positioning protrusions 131a to 133a described later. Further, in FIG. 7, the first to third positioning holes 92 a to 94 a and the first to third positioning protrusions 131 a to 133 a are all shown to be on the same line in order to simplify the description.

Next, the configuration of the switch lever unit 8 will be described.
As shown in FIG. 5, the switch lever unit 8 includes a slide switch lever 12 that turns on and off the switches 7 a and 7 b according to sliding in the axial direction, a switch lever holder 13 that houses the slide switch lever 12, A spring portion 14 is assembled between the slide switch lever 12 and the switch lever holder 13 and generates a biasing force against the pressing force from the step portion 10 against the slide switch lever 12.

  The slide switch lever 12 is provided perpendicularly to the axial direction of the slide bar 121, and a slide bar 121 having a protruding end 121 a that abuts on the stepped portion 10 and slides in the axial direction according to the opening / closing operation of the opening / closing body 2. A switch lever 122 is provided for turning on and off the switches 7a and 7b as the slide bar 121 is slid in the axial direction by the pressing force from the step portion 10 and the urging force from the spring portion 14.

  In addition, the switch lever 122 is configured in a staircase shape having a plurality of surfaces 122a and 122b that are in contact with the switches 7a and 7b. The number of surfaces of the switch lever 122 is changed depending on the number of switches. The switch lever 122 presses all the switches 7a and 7b when the opening / closing body 2 is in the closed position. Then, in accordance with the opening operation of the opening / closing body 2, the pressing of the switches 7a, 7b is sequentially released, and when the opening / closing body 2 is in the open position, the pressing of all the switches 7a, 7b is released.

Further, as shown in FIGS. 5 to 7, the switch lever holder 13 is engaged with the first positioning holes 92 a and 92 b on the front side (right side in FIG. 7) in the direction of assembly to the holder 9. Positioning protrusions 131a and 131b are formed facing forward. In addition, second positioning protrusions 132a and 132b that engage with the second positioning holes 93a and 93b are formed on the rear side in the assembling direction (left side in FIG. 7). Further, third positioning projections 133a and 133b that are engaged with the third positioning holes 94a and 94b at the rear end portions are formed on the bottom surface of the switch lever holder 13.
The number of the first to third positioning holes 92a to 94a, 92b to 94b and the first to third positioning protrusions 131a to 133a, 131b to 133b can be changed as appropriate depending on the length of the switch lever unit 8 and the like.

  The first to third positioning holes 92a to 94a, 92b to 94b and the first to third positioning protrusions 131a to 133a and 131b to 133b serve as holding portions for fixing and holding the assembled switch lever unit 8 to the holder 9. Also works. For example, in FIG. 7, the first to third positioning holes 92 a to 94 a and the first to third positioning protrusions 131 a to 133 a engage with each other, thereby restricting the movement of the switch lever unit 8 in the axial direction. Further, the first and second positioning holes 92a and 93a and the first and second positioning protrusions 131a and 132a are engaged with each other, thereby restricting the switch lever unit 8 from being lifted from the holder 9 (first invention of the present invention). 1 equivalent). In addition, the first and third positioning holes 92a and 94a and the first and third positioning protrusions 131a and 133a are engaged with each other, so that the switch lever unit 8 is separated from the switches 7a and 7b (withdrawal from the holder 9). Direction) (corresponding to the second engaging portion of the present invention).

Next, the configuration of the step portion 10 will be described.
As shown in FIGS. 8 and 10, the stepped portion 10 has a stepped surface (thin surface 101, inclined surface 102 and thick surface 103) formed on the surface orthogonal to the rotating shaft 4 and centered on the rotating shaft 4. It is configured in a staircase shape that thickens toward the side. Here, the protruding end 121a faces the thin surface 101 when the opening / closing body 2 is in the closed position, and moves to the inclined surface 102 and the thick surface 103 as the opening / closing body 2 opens. At this time, with the opening operation of the opening / closing body 2, the protruding end 121a comes into contact with the stepped portion 10, and the slide switch lever 12 is slid inward along the rotation axis.
Note that the maximum projecting position of the projecting end 121a is set so that the projecting end 121a and the thin surface 101 do not abut when the opening / closing body 2 is in the closed position. This is to prevent the slide switch lever 12 from pressing and damaging the switches 7a and 7b when the opening / closing body 2 to which the switch lever unit 8 is assembled is assembled to the fixed body 3.
Further, the shape of the stepped portion 10 can be appropriately changed according to the number of switches, the installation position of the switches and the switch lever unit 8, and the like.

Next, assembly of the switch lever unit 8 configured as described above to the holder 9 will be described.
When the switch lever unit 8 is assembled to the holder 9, first, as shown in FIGS. 7 and 9, first to third positioning holes 92 a to 94 a and 92 b to 94 b formed in the holder 9, and the switch lever unit 8 The first to third positioning protrusions 131a to 133a and 131b to 133b are positioned so that the switch lever 122 faces the switches 7a and 7b disposed on the substrate 11. Next, the switch lever unit 8 is moved in a direction (assembly direction) parallel to the surface of the substrate 11 of the holder 9 and perpendicular to the axial direction of the slide bar 122, and the switch lever unit 8 is assembled to the holder 9.
In this way, the switch 9 can be assembled to the holder 9 only by moving the switch lever unit 8 in the assembling direction, and there is no need to turn the holder 9 over as in the prior art. Therefore, the assembling work becomes easy, and the assembling property with respect to the switch lever unit 8 can be improved.

  Further, the guide portions 91a and 91b play a role of preventing damage to the switches 7a and 7b in addition to the guide function for the switch lever unit 8 during assembly. That is, as shown in FIG. 7C, by forming the guide portions 91a and 91b in the vicinity of the switches 7a and 7b, the switch lever unit 8 tries to press the switches 7a and 7b from above when assembled. Even in this case, the switch lever unit 8 abuts against the upper ends of the guide portions 91a and 91b and cannot move to the switches 7a and 7b, so that the switches 7a and 7b can be prevented from being damaged.

  Further, when the switch lever unit 8 is assembled, the first to third positioning holes 92a to 94a, 92b to 94b and the first to third positioning protrusions 131a to 133a and 131b to 133b are engaged with each other, The switch lever unit 8 assembled to 9 can be fixedly held. That is, it is possible to prevent the switch lever unit 8 from being displaced in the axial direction, lifted, and displaced in the removal direction. Therefore, it is possible to prevent the switch lever unit 8 from being detached from the holder 9.

Secure to body 3. At this time, the protruding end 121 a of the slide switch lever 12 does not come into contact with the thin surface 101. Therefore, it is not necessary to push the slide switch lever 12 into the opening / closing body 2 when assembling the opening / closing body 2 to the fixed body 3 as in the prior art. Therefore, since the slide switch lever 12 does not come into contact with the switches 7a and 7b during assembly, the switches 7a and 7b are not damaged, and the assembly reliability can be improved.

Next, the operation of the switch lever device 6 applied to the display device 1 will be described.
First, when the opening / closing body 2 is in the closed position, as shown in FIG. 8A, the protruding end 121a does not contact the thin surface 101 but protrudes to the maximum protruding position. In this state, as shown in FIG. 10A, the switch lever 122 is in a state where all the switches 7a and 7b are pressed. In this way, it is possible to detect that the opening / closing body 2 is closed by turning on all the switches 7a and 7b.

Next, when the opening / closing body 2 is opened to the first angle, as shown in FIG. 8B, the protruding end 121 a moves to the base side of the stepped portion 10 and comes into contact with the inclined surface 102. Thereafter, along with the opening operation of the opening / closing body 2, the protruding end 121 a moves further to the root side along the inclined surface 102, and the slide switch lever 12 is slid inside the opening / closing body 2.
Next, when the opening / closing body 2 opens to the second angle, as shown in FIG. 10B, the pressing on the switch 7b is released. Thus, when the switch 7b is turned off, it can be detected that the opening / closing body 2 is opened to the second angle.

  Next, when the opening / closing body 2 is opened to the open position, the protruding end 121a reaches the thick surface 103 as shown in FIG. Thereby, as shown in FIG.10 (c), the press with respect to switch 7a is also cancelled | released. As described above, when all the switches 7a and 7b are turned off, it is possible to detect that the opening / closing body 2 is opened to the open position.

  As described above, according to the first embodiment, the first to third positioning holes 92 a to 94 a and 92 b to 94 b formed in the holder 9 and the first to third positioning protrusions 131 a to 131 b formed in the switch lever unit 8. The switch lever unit 8 is positioned parallel to the surface of the substrate 11 and perpendicular to the axial direction of the slide bar 121 with the switch lever 122 facing the switches 7a and 7b disposed on the substrate 11. As a result, it is possible to improve the assembling property when the switch lever unit 8 is assembled to the holder 9.

In the first embodiment, first to third positioning holes 92a to 94a and 92b to 94b are formed in the holder 9, and first to third positioning projections 131a to 133a and 131b to 133b are formed in the switch lever unit 8.
