The conversion spring 8 is a component that transmits the operation of the operating handle 3 to the reversing handle 6. The conversion spring 8 is disposed between the operating handle 3 and the reversing handle 6, and is fixed to the reversing handle 6, for example, and elastically contacts the operating handle 3 (see FIG. 3).

As shown in FIG. 10, the conversion spring 8 includes a pair of spring bodies 81 and a pair of connection pieces 82. The pair of spring bodies 81 each extend in the left-right direction and are arranged vertically. The left ends of the pair of spring bodies 81 are connected by one connecting piece 82, and the right ends of the pair of spring bodies 81 are connected by the other connecting piece 82. The pair of spring bodies 81 are mirror-image symmetrical (that is, vertically symmetrical) with respect to each other. The pair of spring bodies 81 correspond one-to-one to the two side wall portions 61b of the reversing handle 6, and correspond one-to-one to the two pairs of upper and lower contact portions 33 of the operating handle 3.

Each of the pair of spring bodies 81 includes a base plate 81a, a fixed piece 81b, a positioning piece 81c, and a pair of elastic pieces 81d and 81e (a first elastic piece and a second elastic piece). That is, the conversion spring 8 has a pair of base plate parts 81a, a pair of fixed pieces 81b, a pair of positioning pieces 81c, and two pairs of elastic pieces 81d.

The fixed piece 81b has a through hole 8f penetrating in the thickness direction (front-back direction). One of the pair of fitting protrusions 61c of the corresponding side wall portion 61b of the reversing handle 6 fits into the through hole 8f. The positioning piece 81c is a portion that contacts the side surface (for example, the outer surface) of the corresponding side wall portion 61b of the reversing handle 6. The positioning piece 81c protrudes rearward from one end of the substrate portion 81a in the width direction (for example, one end facing the other spring body 81). In this embodiment, the positioning piece 81c protrudes from the rear from both left and right sides of the fixed piece 81b, and the two protruding portions extend in the left-right direction and are connected to each other.

The pair of elastic pieces 81d and 81e are portions that come into contact with the corresponding pair of contact portions 33a and 33b on the operating handle 3. The pair of elastic pieces 81d and 81e extend in the longitudinal direction (left-right direction) from both ends of the substrate portion 81a in the longitudinal direction (left-right direction), and are bent, for example, in an inverted V shape so as to protrude forward. The left ends of the left elastic pieces 81d of the pair of spring bodies 81 are connected by one connecting piece 82, and the right ends of the right elastic pieces 81e of the pair of spring bodies 81 are connected by the other connecting piece 82. There is. The pair of connecting pieces 82 are belt-shaped and extend vertically.

When the conversion spring 8 is fixed to the reversing handle 6 (see FIG. 3), the pair of positioning pieces 81c are in contact with the outer surfaces of the two side walls 61b of the reversing handle 6. Further, the through holes 81f of the pair of fixing pieces 81b fit into one (for example, left side) fitting protrusion of the pair of fitting protrusions 61c of each of the two side wall parts 61b. Due to the above contact and fitting, the relative position of the conversion spring 8 in the vertical and horizontal directions with respect to the reversing handle 6 is fixed. Further, the pair of elastic pieces 81d and 81e are located on both left and right sides of the rotation axis L2 of the reversing handle 6.

Note that in this embodiment, the reversing handle 6 is arranged slightly biased to the right side with respect to the operating handle 3. Therefore, the conversion spring 8 fits into the left fitting protrusion 61c of the two left and right fitting protrusions 61c in order to offset the bias. Thereby, the conversion spring 8 is fixed slightly biased to the left with respect to the reversing handle 6.

Furthermore, when the conversion spring 8 is fixed to the reversing handle 6, the four elastic pieces 81d and 81e elastically contact the four contact parts 33a and 33b of the operating handle 3 (see FIG. 3). More specifically, the pair of left and right elastic pieces 81d and 81e of the upper spring body 81 elastically contact the pair of left and right contact portions 33a and 33b on the upper side of the operating handle 3. The pair of left and right elastic pieces 81d and 81e of the lower spring body 81 elastically contact the pair of left and right contact portions 33a and 33b on the lower side of the operating handle 3.

The outer main surface of the first fitting part 91e faces the front side, and the outer main surface of the second fitting part 91f faces outward in the left-right direction. The second fitting portion 91f projects from the outer end of the first fitting portion 91e in the left-right direction to the back side of the first fitting portion 91e. The first fitting portion 91e is provided in each of the first window portions 311 on the left and right sides of the front surface portion 3t of the operating handle 3, and allows light from the prism 11 (that is, light from the light sources 51a and 51b) to pass therethrough for operation. The light is emitted to the outside of the handle 3. The second fitting portion 91f is provided in each second window portion 312 of the left and right side surface portions 3s of the operating handle 3, and transmits the light from the prism 11 and outputs the light to the outside of the operating handle 3.

The prism body 91b has a substantially trapezoidal flat plate shape when viewed from the front and rear directions. The prism body 91b guides the light from the prism 11 (that is, the light from the light sources 51a and 51b) to the fitting portion 91a. The prism body 91b is arranged on the rear side of the operating handle 3. The prism main body 91b has a narrow end surface 91c having a relatively narrow width in the vertical direction and a wide end surface 91d having a relatively wide width in the vertical direction. The prism body 91b gradually becomes wider from the narrow end surface 91c toward the wide end surface 91d. The prism body 91b is curved toward the front side of the prism body 91b on the way from the narrow end surface 91c to the wide end surface 91d. That is, the prism main body 91b has a curved portion 91h that curves forward on the way from the narrow end surface 91c to the wide end surface 91d. The portion of the prism body 91b on the narrow end surface 91c side extends substantially in the left-right direction, and the portion of the prism body 91b on the wide end surface 91d side extends forward. The wide end surface 91d faces the front side, and the narrow end surface 91c faces inward in the left-right direction.

In these prisms 91L and 91R, the narrow end surface 91c of the prism body 91b serves as the entrance surface 95, and the outer surface of the fitting portion 91a (i.e., the outer main surface 91j of the first fitting portion 91e and the outer side of the second fitting portion 91f) The main surface 91k) becomes the output surface 96. The entrance surface 95 is a surface for taking external light into the prisms 91L, 91R, and the exit surface 96 is a surface for emitting the light propagating within the prisms 91L, 91R to the outside. Since the emission surface 96 faces the front side and the outside in the left-right direction, the light emitted from the emission surface 96 can illuminate the front side and the outside in the left-right direction of the operating handle 3.

The prisms 91L and 91R have a recess 91m (see FIG. 11B). The recessed portion 91m is formed on the rear surface of the prisms 91L, 91R (more specifically, on the rear surface of the prism body 91b) so as to be depressed toward the inside of the prisms 91L, 91R. Note that the rear surfaces of the prisms 91L and 91R are examples of the outer surfaces of the prisms 91L and 91R.

The recessed portion 91m is provided between the prism main body 91b and the second fitting portion 91f on the rear surfaces of the prisms 91L and 9R. The side surface of the recessed portion 91m on the entrance surface 95 side functions as a reflective surface 91n. The reflective surface 91n distributes and guides the light C1 propagating from the entrance surface 95 side inside the prism body 91b to the first fitting part 91e side and the second fitting part 91f side by reflecting it. . The reflective surface 91n is curved, for example, in an arc shape from the opening side of the recessed portion 91m toward the bottom side. The reflective surface 91n is formed by the outer surface of the curved portion 91h of the prism body 91b. The concave portion 91m (particularly the reflective surface 91n) allows the light C1 propagating from the incident surface 95 side inside the prism body 91b to be evenly distributed to the first fitting portion 91e side and the second fitting portion 91f side. can.

The upper ends of the fitting portions 91a of each prism 91L, 91R are connected to each other via one connecting portion 92, and the lower ends of the fitting portion 91a of each prism 91L, 91R are connected to the other connecting portion 92. are connected to each other through. In this state, the entrance surfaces 95L and 95R of the pair of prisms 91L and 91R face inward in the opposing direction (left-right direction) of the pair of prisms 91L and 91R. The output surfaces 96L and 96R of the pair of prisms 91L and 91R face outward and forward in the opposing direction of the pair of prisms 91L and 91R. In each of the prisms 91L and 91R, the entrance surface 95 is located further back than the exit surface 96.

The fixing piece 93 has a substantially rod shape and is provided so as to straddle the center portion of each of the pair of connecting portions 92 . The fixed piece 93 has a fitting hole 93a. The fitting hole 93a is a hole into which the fixing protrusion 34 of the operating handle 3 is fitted.

The light guide member 9 is fixed to the back surface of the operating handle 3 so as to be housed inside the operating handle 3. In this fixed state, as shown in FIG. 4, the pair of fitting portions 91a fit into the pair of light-transmitting windows 31L, 31R. Furthermore, the fixing piece 93 contacts the back surface of the operating handle 3, and the fixing protrusion 34 of the operating handle 3 fits into the fitting hole 93a of the fixing piece 93. Thereby, the light guide member 9 is fixed to the back surface of the operating handle 3. In addition, in this fixed state, the incident surfaces 95L and 95R of the pair of prisms 91L and 91R face each other at the center of the back surface of the operating handle 3 with an interval in the longitudinal direction (horizontal direction) of the operating handle 3. will be placed. Input surfaces 95L and 95R of the pair of prisms 91L and 91R are arranged adjacent to (on the rear side) the tips of the pair of light shielding parts 10L and 10R. The light guide member 9 is fixed to the operating handle 3 and operates integrally with the operating handle 3.

The prism 11 is a member that branches the light from the light sources 51a and 51b into two, and emits the branched lights toward the pair of light-transmitting windows 31L and 31R, respectively. The prism 11 selectively guides the light from the light sources 51a and 51b to one of the prisms 91L and 91R on both sides according to the see-saw movement of the operating handle 3. The prism 11 has a prism body 12 and two branch paths 13 and 14, as shown in FIG. Moreover, the prism 11 has two entrance surfaces 11a and 11b, and two exit surfaces 11L and 11R.

The prism body 12 receives light from the light sources 51a and 51b, and guides the incident light to two branch paths 13 and 14. The prism body 12 has a first light guide section 121 and a second light guide section 122. The two incident surfaces 11a and 11b are formed on one end surface of the first light guide section 121. The entrance surface 11b is arranged on the right side of the entrance surface 11a (next to the side on which the second light guide section 122 extends). The first light guide portion 121 extends in an oblique direction (for example, diagonally to the front right) with respect to the optical axes L4 and L5 of the incident surfaces 11a and 11b. Optical axes L4 and L5 of the entrance surfaces 11a and 11b extend in the same direction, for example, in the front-rear direction. The second light guiding section 122 extends from one end (for example, the right end) of the first light guiding section 121 in a direction perpendicular to the optical axes L4 and L5 of the incident surfaces 11a and 11b (in the left-right direction). The two branch paths 13 and 14 extend from one end of the second light guide 122 (that is, the end opposite to the first light guide 121, for example, the right end) to the incident surfaces 11a and 11b (rear). side) and protrudes on the opposite side (front side). In this embodiment, the optical axes L4 and L5 of the entrance surfaces 11a and 11b coincide with the optical axes of the light sources (light sources 51a and 51b in this embodiment) that make light enter the entrance surfaces 11a and 11b. Hereinafter, the optical axes L4 and L5 will also be referred to as the optical axes of the light sources 51a and 51b.

The first light guide section 121 has a left side surface 121a (first reflective surface) and a right side surface 121b (second reflective surface). The left side surface 121a and the right side surface 121b are side surfaces adjacent to both sides of the above-mentioned one end surface where the incident surfaces 11a and 11b are provided. The left side surface 121a is inclined 45 degrees to the right with respect to the optical axes L4, L5 of the entrance surfaces 11a, 11b, and overlaps with the above-mentioned one end surface in the direction of the optical axes L4, L5. The right side surface 121b is a surface parallel to the left side surface 121a, and does not overlap with the above-mentioned one end surface in the direction of the optical axes L4 and L5.

The second light guide section 122 has a right side surface 122a (third reflective surface). The right side surface 122a is a side surface of the second light guide section 122 that is opposite to the side connected to the first light guide section 121. The right side surface 122a is a surface parallel to the left side surface 121a of the first light guide section 121, and is inclined at 45 degrees to the right with respect to the optical axes L4 and L5 of the incident surfaces 11a and 11b. The right side surface 122a overlaps with the left side surface 121a of the first light guide section 121a in the left-right direction (the direction in which the second light guide section 122 extends) orthogonal to the optical axes L4 and L5. The right side surface 122a is arranged so as to face the base ends of the two branch paths 13 and 14 (the connecting surface with the second light guide section 122) in the direction of the optical axes L4 and L5.

The two branch paths 13 and 14 are formed integrally with the prism main body 12, branch the light propagating through the prism main body 12 into two, and emit the branched lights to the outside from the output surfaces 11L and 11R, respectively. The two branch paths 13 and 14 extend from one end (right end) of the second light guide section 122 to the entrance surface 1.
It protrudes to the side (front side) opposite to the side (rear side) of 1a and 11b. The two branch paths 13 and 14 are arranged side by side in the direction in which the second light guide section 122 extends (horizontal direction), and are inclined outward in the opposing direction (horizontal direction). The two branch paths 13 and 14 correspond one-to-one to the pair of light-transmitting windows 31L and 31R.

The two exit surfaces 11L and 11R are formed by one end surface of each of the two branch paths 13 and 14. Each output surface 11L, 11R is, for example, a plane. The normal lines of the two output surfaces 11L and 11R face substantially opposite directions. The normal lines of the two output surfaces 11L and 11R generally face the direction of the corresponding light-transmitting windows 31L and 31R. The two branch paths 13 and 14 have opposing side surfaces 13a and 14a. Opposing side surfaces 13a and 14a are side surfaces of the two branch paths 13 and 14 that face each other. Opposing side surfaces 13a, 14a of the branch paths 13, 14 face the output surfaces 11L, 11R provided in the branch paths, and are inclined with respect to the optical axes L4, L5 of the incident surfaces 11a, 11b. This inclination is such that the light emitted from the emission surfaces 11L, 11R is approximately emitted in the direction of the corresponding light-transmitting windows 31L, 31R.

The light from the first light source 51a enters the entrance surface 11a. The light from the second light source 51b enters the entrance surface 11b. The two incident surfaces 11a and 11b are lined up in the direction in which the second light guide section 122 extends (left-right direction). The two entrance surfaces 11a and 11b have, for example, a semi-convex lens shape, but may also have a planar lens shape. Although the two entrance surfaces 11a and 11b are arranged to be offset from each other in the directions of the optical axes L4 and L5, they do not need to be offset from each other.

The prism body 12 has a slit 15. The slit 15 constitutes a reflective surface that reflects the light propagating within the prism body 12. The slit 15 is a thin plate-shaped through hole that penetrates the prism body 12 in the thickness direction (vertical direction). The slit 15 is provided at a connecting portion between the first light guide section 121 and the second light guide section 122. In other words, the slit 15 is arranged between the two side surfaces 121a, 121b in the direction of the optical axes L3, L4, and between the two side surfaces 121a, 122a in the left-right direction perpendicular to the optical axes L3, L4. has been done. The slit 15 is parallel to each side surface 121a, 121b, 122a, and is inclined at 45 degrees to the right with respect to the optical axis L4, L5 of the entrance surface 11a, 11b.

Prism 11 further includes a pair of fitting protrusions 16 . The pair of fitting protrusions 16 are provided so as to protrude from both main surfaces of the prism 11 (more specifically, for example, the second light guide section 122) in the vertical direction. The pair of fitting protrusions 16 fit into the pair of fitting recesses 22i of the prism 11. Due to this. The prism 11 is fixed to the vessel body 2 (more specifically, the second opening 22e of the cover 22).

In this fixed state, the two branch passages 13 and 14 of the prism 11 protrude toward the front side of the cover 22 from approximately the center of the cover 22, as shown in FIG. Note that the right side portion of the second light guiding portion 122 of the prism 11 is arranged between the two side wall portions 61b of the reversing handle 6. Further, the prism body 12 of the prism 11 extends diagonally to the rear left of the cover 22 from approximately the center of the cover 22. More specifically, the second light guide section 122 of the prism 11 is arranged along the front surface of the cover 22, and the first light guide section 121 of the prism 11 extends diagonally to the left and rearward of the cover 22. The two entrance surfaces 11a and 11b of the prism 11 are arranged in front of the two light sources 51a and 51b of the light source unit 5, respectively.

The manner in which light propagates within the prism 11 will be described with reference to FIG. 13.

In this prism 11, the light C1 emitted in the front direction from the first light source 51a passes through the entrance surface 11a, is reflected on the left side surface 121a, and propagates in the right direction. Then, the light C1 is reflected by the right side surface 121b and propagates forward. At this time, the left side light C1a of the light C1 propagated in the front direction is not reflected by the slit 15, but propagates in the front direction and is reflected by the left side surface 121a. Then, the light C1a propagates forward while repeating reflection between the left side surface 121a and the slit 15, and when it propagates to the front side of the slit 15, it is reflected on the left side surface 121a and propagates to the right, to the right side. The light enters a region R1 near the front of the center position P1 of the surface 122a. Then, the light C1a is reflected forward by the right side surface 122a and propagates into the right branch path 14. The light C1a propagates while being reflected within the right branch path 14, and is emitted from the exit surface 11R toward the right transparent window 31R.

On the other hand, the right light C1b of the light C1 is reflected by the slit 15, propagates to the right, and enters the region R2 located at the rear of the center position of the right side surface 122a. That is, the light C1b enters a region R2 different from the region R1. Then, the light C1b is reflected forward by the right side surface 122a and propagates into the left branch path 13. The light C1b propagates while being reflected within the left branch path 13, and is emitted from the exit surface 11L toward the left transparent window 31L. Note that the center position P1 of the right side surface 122a is a position where it intersects with a line L6 drawn from the boundary point P2 of the two branch paths 13 and 14 in parallel to the optical axes L3 and L4.

In this way, the light C1 from the first light source 51a propagates within the prism 11, and is split almost equally into two within the prism 11, and is emitted from the two exit surfaces 11L and 11R.

Further, as shown in FIG. 14, in this prism 11, the left side light C2a of the light C2 emitted in the forward direction from the second light source 51b passes through the entrance surface 11b and is reflected by the left side surface 121a. Propagates to the right. Then, the light C2a enters the rear region R3 of the right side surface 122a, is reflected forward by the right side surface 122a, and propagates into the left branch path 13. Note that the light C2a is incident on a region R3 different from the regions R1 and R2. The light C2a propagates while being reflected within the left branch path 13, and is emitted from the exit surface 11L toward the left transparent window 31L.

On the other hand, the right light C2b of the light C2 from the second light source 51b propagates forward and is reflected by the left side surface 121a. The light C2b propagates forward while repeating reflection between the left side surface 121a and the slit 15, and when it propagates to the front side of the slit 15, it is reflected on the left side surface 121a and propagates to the right, and is propagated to the right side surface 122a. The light enters the front region R4. That is, the light C2b enters a region R4 that is different from the regions R1 to R3. Then, the light C2b is reflected forward by the right side surface 122a and propagates into the right branch path 14. The light C2b propagates while being reflected within the right branch path 14, and is emitted from the exit surface 11R toward the right transparent window 31R.

In this way, the light C2 from the second light source 51b propagates within the prism 11, and is split almost equally into two within the prism 11, and is emitted from the two exit surfaces 11L and 11R.

Note that when the lights C1 and C2 from the light sources 51a and 51b are made incident on the prism 11 at the same time, the propagation of the light C1 in FIG. 13 and the propagation of the light C2 in FIG. 14 are superimposed. The lights C1 and C2 from the two light sources 51a and 51b are split into two substantially equally and emitted from the two exit surfaces 11L and 11R, respectively. That is, by one prism 11, the lights C1 and C2 from the two light sources 51a and 51b, which are arranged to be shifted from each other in the left-right direction, are split into two substantially equally and emitted from the two output surfaces 11L and 11R. can. In this case, the lights C1a, C1b, C2a, and C2b are incident on mutually different regions R1 to R4 and reflected to the branch paths 13 and 14.

In this prism 11, among the inner surfaces of the prism body 12, the surfaces on which light is reflected (right side surfaces 121b, 122a, left side surface 121a, and slit 15) are mutually arranged with respect to the optical axes L4, L5 of the incident surfaces 11a, 11b. They are tilted 45 degrees to the same side (for example, the right side).

In this switch device 1, the light sources 51a and 51b are arranged to be shifted to the left from the center in the left-right direction (longitudinal direction) in the body 21. However, by using the prism 11, the light from the light sources 51a and 51b can be split into two substantially equally and emitted from the two output surfaces 11L and 11R.

Next, referring to FIG. 3, the operation of the switch device 1 (operation of the operating handle 3 and the reversing handle 6) will be described.

When one of the operating parts 3L and 3R on both sides of the operating handle 3 (for example, the left operating part 3L) is pressed (operated), the operating handle 3 rotates around the rotation axis L1 (see FIG. 8). Then, the other (for example, the right operating section 3R) is lifted forward from the front surface 22j of the cover 22. In this state, the conversion spring 8 elastically supports the operating handle 3 so as to maintain this operating state of the operating handle 3.

At this time, the operating force when one of the operating handles 3 is pressed down is transmitted to the reversing handle 6 via the conversion spring 8. At this time, the four elastic pieces 81e and 81d of the conversion spring 8 come into elastic contact with the corresponding contact portions 33 of the operating handle 3. In this contact state, the four elastic pieces 81e and 81d slide on the corresponding contact portions 33 along the longitudinal direction of the contact portions 33 according to the operation of the operation handle 3, and receive the above-mentioned operation force and reverse. The signal is transmitted to the handle 6. Thereby, the above-mentioned operating force is smoothly transmitted from the operating handle 3 to the reversing handle 6. That is, the reversing handle 6 rotates smoothly around the rotation axis L2 (see FIG. 9) in accordance with the operation of the operating handle 3. In this case, the right side of the operation parts 3L and 3R on both the left and right sides of the reversing handle 6 (that is, the part on the same side as the operation part on the pressed side of the operation handle 3) is pressed down by the conversion spring 8, It rotates around the rotation axis L2. This rotation switches the opening/closing contacts of the contact device 4.

Further, in this switch device 1, the rotation axis L2 of the reversing handle 6 is shifted to the right with respect to the rotation axis L1 of the operating handle 3. Therefore, the timing at which the reversing handle 6 operates according to the operation of the operating handle 3 is determined by when the left operating part 3L of the operating handle 3 is pressed and when the right operating part 3R of the operating handle 3 is pressed. may be different. Specifically, in this case (when the rotation axis L2 is shifted to the right with respect to the rotation axis L1), when the left operation part 3L of the operation handle 3 is pressed down, the right side of the operation handle 3 The above timing is later than when the operation section 3R is pressed.

On the other hand, in this switch device 1, among the four contact parts 33 of the operating handle 3, the left contact part 33a and the right contact part 33b have different undulating shapes. Specifically, the undulating shape of the right contact portion 33b is made curved to make it difficult to transmit the operating force, and the undulating shape of the left contact portion 33a is made linear to facilitate the transmission of the operating force. As a result, no matter which of the operating parts 3L and 3R on both sides of the operating handle 3 is pressed, the reversing handle 6 operates at the same timing. As a result, no matter which of the operating parts 3L and 3R on both sides of the operating handle 3 is pressed, the operating feeling is the same.

In this way, in this switch device 1, the operating handle 3 and the reversing handle 6 are movable around separate rotational axes L1 and L2, and the operation of the operating handle 3 is transmitted to the reversing handle 6 by the conversion spring 8. Therefore, by adjusting the way in which the conversion spring 8 and each handle 3, 6 come into contact with each other, the operation (for example, the rotation angle and rotation speed) of each handle 3, 6 can be adjusted independently. Furthermore, by making the rotation angle of the reversing handle 6 smaller than the rotation angle of the operating handle 3, the space for the reversing handle 6 within the container body 2 can be reduced, and the degree of freedom in the arrangement and layout of each component can be improved. .

Next, with reference to FIG. 4, the operations of the pair of light shielding parts 10L, 10R and the pair of prisms 91L, 91R of the switching device 1 will be described.

In this switch device 1, when one of the operating parts 3L and 3R on both sides of the operating handle 3 is pressed down (for example, the left operating part 3L), the other (for example, the right operating part 3R) is pressed down. It is lifted forward from the front surface 22j. In response to the operation of the operating handle 3, the pair of light shielding parts 10L, 10R and the pair of prisms 91L, 91R provided on the operating handle 3 move toward the prism 11 (more specifically, the two exit surfaces 11L, 11R). relative displacement.

More specifically, of the pair of light shielding parts 10L and 10R, the light shielding part 10R provided on the raised one of the operation parts 3L and 3R on both sides of the operation handle 3 (the right hand operation part 3R) is connected to the prism 11. is displaced to a position that does not block the front of the corresponding output surface 11R (for example, a position shifted to the front side of the output surface 11R). Thereby, the light emitted from the corresponding output surface 11R of the prism 11 is not blocked by the light shielding part 10R, and is emitted toward the corresponding light-transmitting window 31R. On the other hand, the light shielding section 10L provided on the pressed one of the operating sections 3L and 3R on both sides of the operating handle 3 (for example, the left operating section 3L) is located at a position that blocks the front of the corresponding output surface 11L of the prism 11. (For example, the front position of the output surface 11L). Thereby, the light emitted from the corresponding light emitting surface 11L of the prism 11 is blocked by the light blocking portion 10L, and is not emitted toward the corresponding light transmitting window 31L.

In addition, among the pair of prisms 91L and 91R, the prism 91R provided on the raised one of the operating parts 3L and 3R on both sides of the operating handle 3 (for example, the right operating part 3R) It is displaced to the front position of the surface 11R (that is, a position where the light emitted from the output surface 11R can enter from the entrance surface 95R). Thereby, the light emitted from the exit surface 11R of the prism 11 enters the entrance surface 95R of the prism 91R and is emitted from the exit surface 96R. That is, the light emitted from the exit surface 11R of the prism 11 is emitted from the light-transmitting window 31R. On the other hand, the prism 91L provided on the pressed one of the operating parts 3L and 3R on both sides of the operating handle 3 (for example, the left operating part 3L) is moved, for example, from the front of the corresponding output surface 11L of the prism 11 to the rear. It is displaced to a removed position (ie, a position where the light emitted from the output surface 11L cannot enter from the input surface 95L). As a result, the light emitted from the exit surface 11L of the prism 11 does not enter the entrance surface 95L of the prism 91L, and is not emitted from the corresponding light-transmitting window 31L.

As a result, out of the pair of light-transmitting windows 31L, 31R, the light source 51a, Light from 51b is emitted. This emitted light causes the front surface portion 3g and side surface portion 3s of the raised operating section (for example, the right operating section 3R) to emit light. The light from the light sources 51a and 51b is not emitted from the light-transmitting window 31L on the pressed side (for example, the left operating section 3L). The front surface 3g and side surface 3s of the pressed operation section (for example, the left operation section 3L) do not emit light.

Next, with reference to FIG. 4, the lighting operation (position display function and pilot function) of the switch device 1 will be explained.

In this switch device 1, the light source 51a (for example, a white light source) is always turned on. Thereby, light (for example, white light) from the light source 51a always enters the entrance surface 11a of the prism 11 and exits from the two exit surfaces 11L and 11R of the prism 11. As a result, the light from the light source 51a is emitted only from the raised light-transmitting window of the operating portions 3L, 3R on both sides of the operating handle 3 among the pair of light-transmitting windows 31L, 31R. That is, when the operation handle 3 is operated and one of the operation parts 3L and 3R on both sides of the operation handle 3 is lifted, the light-transmitting windows 31L and 31R of the lifted side always emit white light, for example. . Thereby, the position of the operating handle 3 can be easily recognized even in the dark due to the light emission (position display function).

On the other hand, in this switch device 1, the light source 51b (for example, a red light source) is turned on and off in accordance with the activation and deactivation of the load to be operated. For example, the light source 51b is turned off when the load to be operated is in operation, and is turned on when the load to be operated is stopped.

As a result, when the load to be operated is in operation, the light source 51b is turned off, so even if the operating handle 3 is operated and one of the operating parts 3L and 3R on both sides of the operating handle 3 is lifted, The light from the light source 51b is not emitted from the raised transparent windows 31L and 31R. That is, the raised light-transmitting windows 31L and 31R do not emit light. On the other hand, when the load to be operated is stopped, the light source 51b is turned on, so when the operating handle 3 is operated and one of the operating parts 3L and 3R on both sides of the operating handle 3 is lifted, it is lifted. Light (for example, red light) from the light source 51b is emitted from the transparent windows 31L and 31R on the other side. That is, the raised light-transmitting windows 31L and 31R emit red light. Thereby, by the light emission, it is possible to easily see the part of the operation handle 3 for operating the load to be operated even in the dark (pilot function). In addition, in this embodiment, since the pilot function and the position display function are implemented together, in this case, red light from the pilot function and white light from the position display function are emitted from the transparent windows 31L and 31R. .

(Main effect)
As described above, the switch device 1 according to the present embodiment includes the operating handle 3, the contact device 4 (contact circuit), the light sources 51a and 51b, and the prisms 91L and 91R (light-transmitting members). The operating handle 3 can be operated by an operator. The contact device 4 switches between an open state and a closed state according to the operation of the operating handle 3. The light sources 51a and 51b are arranged on the rear side of the operating handle 3. The prisms 91L and 91R are provided on the operating handle 3. The operating handle 3 has a front part 3t and a side part 3s. The prisms 91L and 91R have a first fitting part 91e (first light emitting part) and a second fitting part 91f (second light emitting part). The first fitting portion 91e is provided on the front surface 3t of the operating handle 3, and transmits the light from the light sources 51a, 51b to the outside (for example, the front side) of the operating handle 3. The second fitting portion 91f is provided on the side surface 3s of the operating handle 3, and transmits the light from the light sources 51a and 51b to the outside (for example, the side surface) of the operating handle 3.

According to this configuration, the front part 3t and the side part 3s of the operating handle 3 can be made to emit light. By causing the side surface portion 3s to emit light, the light emitted from the operating handle 3 can be visually recognized from the side of the operating handle 3. Moreover, by causing the side surface portion 3s to emit light, it is possible to suppress the light from the operating handle 3 from directly entering the eyes when viewed from the front side of the operating handle 3.

(Modified example)
Next, a modification of the above embodiment will be described. The following variations may be implemented in combination.

(Modification 1)
In the embodiment described above, the first window portion 311 and the second window portion 312 of the light-transmitting windows 31L and 31R are integrated to form one light-transmitting window. Further, the first fitting part 91e (first light emitting part) and the second fitting part 91f (second light emitting part) of the fitting part 91a (light emitting part) are also integrated to form one transparent window. Configure. However, as shown in FIG. 15, the first window section 311 and the second window section 312 may be formed separately, and the first fitting section 91e and the second fitting section 91f may also be formed separately.

(Modification 2)
In the above embodiment, as shown in FIG. Three fitting portions 91p may be provided. The transparent windows 31L and 31R in this case have a first window section 311, a second window section 312, and a third window section 313. In this case, the fitting portion 91a (light emitting portion) includes a first fitting portion 91e (first light emitting portion), a second fitting portion 91f (second light emitting portion), and a third fitting portion 91p (second light emitting portion). 3 light emitting parts). Note that the upper and lower side surfaces 3v of the operating handle 3 intersect both the front surface 3t and the side surface 3s of the operating handle 3. The front part 3t and the side part 3s intersect with each other. The third fitting part 91p is connected to the prism bodies 9b of the prisms 91L and 91R, and can emit light similarly to the first fitting part 91e and the second fitting part 91f. That is, the operating handle 3 in this case allows light to be emitted from the left and right edges of the front portion 3t, the left and right side portions 3s (3e, 3f), and the left and right edges of the upper and lower side portions 3v. It is.

The upper side surface portion 3v of the operating handle 3 is comprised of the upper side surface portion 3u of the left and right operating portions 3L, 3R, and the lower side surface portion 3v of the operating handle 3 is comprised of the upper side surface portion 3u of the left and right operating portions 3L, 3R. It is composed of a lower side surface portion 3u of 3R. The third window portion 313 may be provided on at least a portion of the side surface portion 3v of the operating handle 3.

In this modification, as shown in FIG. 16, the first window section 311, the second window section 312, and the third window section 313 are formed separately, and the first fitting section 91e and the second fitting section 91g and the third fitting part 91p are also formed separately.

However, as shown in FIG. 17, the first window section 311, the second window section 312, and the third window section 313 are integrated to constitute one light-transmitting window 31L, 31R, and the first fitting section 91e , the second fitting part 91f and the third fitting part 91p may also be integrated to form one fitting part 91a. In the example of FIG. 17, the light-transmitting windows 31L and 31R are formed on the entire left and right end surfaces of the operating handle 3. The fitting portions 91a of the prisms 91L and 91R have a hexahedral box shape, and four of the six surfaces are a first fitting portion 91e, a second fitting portion 91f, and third fitting portions on both upper and lower sides. 91p, and the remaining two surfaces (the lower surface and the inner surface in the left-right direction) are open. Of the two open surfaces of the fitting part 91a, the inner side in the left and right direction is aligned with the translucent windows 31L, 31R, and the lower surface is adjacent to the lower surface of the operating handle 3. Provided at both ends.

(Modification 3)
As shown in FIGS. 18A and 18B, the switch device 1 of this modification further includes a panel member 200 in the modification 1, and the light is emitted from the second window 312 of the side surface 3s of the operation handle 3. The front surface 200a of the panel member 200 is illuminated by the light C1.

The panel member 200 is, for example, a design panel, and has a plate shape with an opening 200b. The panel member 200 is arranged so as to expose the operating handle 3 from the opening 200b and cover the outer periphery of the operating handle 3 (ie, the front surface of the cover 22). The side surface portions 3s of the raised operation parts 3L and 3R of the operation handle 3 are arranged on the front side of the front surface 100a of the panel member 200.

In this modification, the prism bodies 91b (light guiding portions) of the prisms 91L and 91R are branched into a first fitting portion 91e (first light emitting portion) and a second fitting portion 91f (second light emitting portion). are doing. More specifically, the prism main body 91b has a first branching path 91r and a second branching path 91s, one end of each of the first branching path 91r and the second branching path 91s is a first fitting portion 91e and a first fitting portion 91e, respectively. It is connected to the back surface of each of the second fitting parts 91f. The other end portions of the first branch path 91r and the second branch path 91s are bundled together to form a common light guide path. The end face of the common light guide path constitutes the entrance surface 95.

The prisms 91L and 91R have a recess 91m. The recessed portion 91m is formed so as to be depressed toward the inside of the second branched path 91s on the rear surface of the prism body 91b (more specifically, the rear surface of the second branched path 91s). The side surface of the recessed portion 91m on the entrance surface 95 side functions as a reflective surface 91n. The reflective surface 91n is curved, for example, in an arc shape from the opening side of the recessed portion 91m toward the bottom side. Note that the rear surface of the prism body 91b is an example of the outer surface of the prism body 91b.

The reflective surface 91n reflects the light C1 propagating from the entrance surface 95 side inside the second branch path 91s. As a result, when the light C1 is emitted from the second fitting part 91f to the outside, the reflecting surface 91n directs the light C1 diagonally backward from the second fitting part 91f (i.e. around the front surface 200a of the panel member 200). (towards area W1). Thereby, the front surface 200a of the panel member 200 can be illuminated with the light C1. Note that the surrounding area W1 is a surrounding area of the side surface portions 3s of the raised operating portions 3L and 3R on the front surface 200a of the panel member 200.

As described above, since the prisms 91L and 91R have the concave portions 91m, the front surface 200a of the panel member 200 can be effectively illuminated by the light C1 emitted from the second window portion 312 of the side surface portion 3s of the operation handle 3. I can do it.

In this modification, at least a portion (for example, the surrounding area W1) of the front surface 200a of the panel member 200 may be textured (for example, minute irregularities). By the graining process, the reflected light of the light C1 irradiated onto the front surface 200a of the panel member 200 can be made light that is easy on the eyes and suppresses glare.

(Modification 4)
In the above embodiment, the prisms 11, 91L, 91R are used to distribute the light from the common light sources 51a, 51b to the left and right operating units 3L, 3R. However, as shown in FIG. 19, instead of using the prisms 11, 91L, 91R to distribute the light from the light sources 51a, 51b to the operation parts 3L, 3R on both sides, the light source 51c. In this case, each light source 51c is arranged, for example, on the rear side of the corresponding operation section 3L, 3R. In addition, each light source 51c is arranged so that the light source 51c corresponding to the raised operation part (for example, 3R) of the operation handle 3 emits light, and the light source 51c corresponding to the pressed operation part (for example, 3L) is turned off. may be controlled.

(Modification 5)
In the above embodiment, windows (first window 311 and second window 312) are provided on both the front surface 3t and side surface 3s of the operating handle 3, and light can be emitted from both windows 311, 312. shall be. However, as shown in FIG. 20, a window 311 may be provided only on the front surface 3t of the front surface 3t and side surface 3s of the operating handle 3, and light may be emitted only from the window 311 on the front surface 3t. .

In this case, the fitting portion 91a (light emitting portion) of the prisms 91L, 91R is the first fitting portion 91e (first light emitting portion) and the second fitting portion 91f (second light emitting portion). It has only one fitting part 91e. The prism bodies 91b (light guide portions) of the prisms 91L and 91R are curved forward and connected only to the back surface of the first fitting portion 91e.

More specifically, the prism body 91b has a curved portion 91h that curves forward on the way from the entrance surface 95 to the exit surface 96. The portion of the prism body 91b on the entrance surface 95 side extends substantially in the left-right direction, and the portion of the prism body 91b on the exit surface 96 side extends forward. The light C2 propagating inside the prism body 91b from the entrance surface 95 side is reflected by the outer surface of the curved portion 91h and guided to the exit surface 96 side.

According to this modification, only the front part 3t of the front part 3t and the side part 3s of the operation handle 3 can be made to emit light.

(Modification 6)
As shown in FIG. 21, in the third modification example including the panel member 200, the window portion 312 is provided only on the side surface portion 3s of the front surface portion 3t and side surface portion 3s of the operation handle 3, and the window portion 312 is provided on the side surface portion 3s only. The light C3 can be emitted only from the window portion 312. In this case, the fitting portion 91a (light emitting portion) of the prisms 91L, 91R is the first fitting portion 91e (first light emitting portion) and the second fitting portion 91f (second light emitting portion). It has only two fitting parts 91f. That is, the prism body 91b extends substantially in the left-right direction. The prism bodies 91b (light guiding portions) of the prisms 91L and 91R have only the second branching path 91s among the first branching path 91r and the second branching path 91s, and are connected only to the back surface of the second fitting portion 91f. . That is, the prism body 91b extends substantially in the left-right direction.

The prisms 91L and 91R (light-transmitting members) in this case also have a recess 91m as in the third modification, and the side surface of the recess 91m on the incident surface 95 side functions as a reflective surface 91n. As a result, when the light C3 is emitted from the second fitting part 91f to the outside by the reflective surface 91n, the light C3 is directed diagonally backward from the second fitting part 91f (i.e., toward the panel The light is emitted toward the peripheral region W1 (see FIG. 18B) of the front surface 200a of the member 200. Thereby, the front surface 200a of the panel member 200 can be illuminated with the light C3. Note that the surrounding area W1 is a surrounding area of the side surface portions 3s of the raised operating portions 3L and 3R on the front surface 200a of the panel member 200. In this case, for example, approximately 50% of the light C3 emitted from the second fitting portion 91f may illuminate the front surface 200a of the panel member 200.

In this modification, as in modification 3, the prisms 91L and 91R have the concave portions 91m, so that the light C3 emitted from the second window 312 of the side surface 3s of the operation handle 3 can effectively protect the panel. The front surface 200a of the member 200 can be illuminated.

(Modification 7)
In the above embodiment, at least one of the surface of the first fitting part 91e (first light emitting part) and the surface of the second fitting part 91f (second light emitting part) of the operating handle 3 is textured (e.g. (Minute irregularities) may be applied. As a result, the texturing process allows the light emitted from the first fitting part 91e and the second fitting part 91f to be light that is easy on the eyes and suppresses glare.

(Modification 8)
In the above embodiment, when the load to be operated is in operation, the light source 51b is turned off, and when the load to be operated is stopped, the light source 51b is turned on. However, conversely, when the load to be operated is in operation, the light source 51b may be turned on, and when the load to be operated is stopped, the light source 51b may be turned off. In this case, only when the load to be operated is in operation, the light-transmitting window of the pair of light-transmitting windows 31L, 31R that is lifted out of the operating parts 3L, 3R on both sides of the operating handle 3 emits light. .

(Modification 9)
In the above embodiment, the prism 11 may be fixed to the operating handle 3 instead of being fixed to the cover 22 (ie, the vessel body 2). Furthermore, the light guide member 9 (that is, the pair of prisms 91L and 91R) may be fixed to the cover 22 instead of being fixed to the operating handle 3. The pair of light shielding parts 10L and 10R may be fixed to the cover 22 instead of being fixed to the operating handle 3. Further, instead of being fixed to the reversing handle 6 and elastically contacting the operating handle 3, the conversion spring 8 may be fixed to the operating handle 3 and elastically contacting the reversing handle 6.

(Modification 10)
In the above embodiment, the pair of light shielding parts 10L, 10R and the light guide member 9 (the pair of prisms 91L, 91R) are exemplified as an example of the light transmission control mechanism. Note that the light transmission control mechanism is configured to emit the light guided by the prism 11 from only one of the pair of light transmission windows 31L and 31R, depending on the operating state of the operating handle 3. It is a mechanism that allows In the above embodiment, one or both of the pair of light shielding parts 10L, 10R and the light guide member 9 may be omitted.

(Modification 11)
In the above embodiment, the light source 51b is switched on and off depending on the conduction and non-conduction between the open/close contacts in the closed state, but the operating state of the operation handle 3 (i.e., the operating state of the operation handle 3 (i.e., the Depending on which one is pressed, lighting and extinguishing may be switched.

(Other variations)
In the above embodiment, the operating handle 3 is a seesaw switch, but it may also be a piano switch or a push button switch.

(summary)
The switch device (1) of the first aspect includes an operation handle (3), a contact circuit (4), a light source (51a, 51b), and a light-transmitting member (91L, 91R).
