(First information presentation unit 20)
The first information presentation unit 20 is formed of a plate-shaped polarizing plate and functions as a presentation filter. The first information presentation unit 20 is, for example, a polarizing plate sandwiched between protective films that protect the upper and lower sides of a polarizing layer having a polarizing function. The polarizing layer forms, for example, a PVA (polyvinyl alcohol) layer, and adsorbs an iodine pigment to perform boric acid crosslinking. After drying and stabilization, the PVA layer is stretched to orient the iodine pigment and develop polarization.

  The above iodine dye is stretched in a direction orthogonal to the first polarization direction 23. Light having a polarization component parallel to this stretching direction (direction orthogonal to the first polarization direction 23) is reflected or absorbed and does not pass through the PVA layer. On the other hand, light having a polarization component perpendicular to the stretching direction is transmitted.

  As shown to FIG. 3A (a), the 1st information presentation part 20 is equipped with the 1st polarization direction 23 which extends a pigment | dye and has a polarization function. The first polarization direction 23 is orthogonal to the extending direction of the dye. The light linearly polarized in the same direction as the first polarization direction 23 is transmitted. Further, the light linearly polarized in the direction orthogonal to the first polarization direction 23 is not transmitted.

  Here, the 1st permeation | transmission part 22 shown to FIG. 3A (a) is an area | region which sublimated the iodine pigment | dye of the PVA layer by laser irradiation etc., and has disappeared. Thereby, the 1st transmission part 22 does not have a polarization function, but can permeate | transmit light irrespective of a polarization state.

Accordingly, the first information presentation unit 20 functions as a presentation filter. The shapes of the first polarizing unit 21 and the first transmitting unit 22 can display a figure such as a predetermined mark or character by a combination with a second information presentation unit 30 described later.

(Second information presentation unit 30)
The 2nd information presentation part 30 is also formed with a plate-shaped polarizing plate by the same composition as the 1st information presentation part 20, and functions as a presentation filter. The second information presentation unit 30 is provided in the operation unit 10 so as to partially overlap the first information presentation unit 20, and is irradiated with light having a second polarization direction 33 different from the first polarization direction 23. It is configured as follows. Here, the first polarization direction 23 and the second polarization direction 33 are orthogonal to each other.

  As shown in FIGS. 3A (c) and 3 (d), the second information presentation unit 30 transmits the linearly polarized light polarized in the second polarization direction 33 and the polarization state. It has the area | region of the 2nd transmission part 32 which permeate | transmits light, and is comprised. Therefore, the second information presentation unit 30 functions as a presentation filter. The shape of the second polarizing unit 31 and the second transmitting unit 32 can display a figure such as a predetermined mark or character by a combination with the first information presentation unit 20 described above.

(First light emitting part)
For the first light emitting unit 40, for example, laser light, LED light, or the like can be used. For example, in the case of laser light, the polarization direction is adjusted so as to have a polarization component in a specific direction, and in the case of LED light or the like, a polarization element is arranged in the emission part so as to have a polarization component in a specific direction. In the present embodiment, an LED light source is used as the first light emitting unit 40, and the first polarizing plate 45 is disposed in the emitting unit.

  The first light emitting unit 40 emits light having a polarization direction in the first polarization direction 23 illustrated in FIG. The light emitted from the first light emitting unit 40 through the first polarizing plate 45 can pass through the entire area of the second transmission unit 32 and the first information presentation unit 20 of the second information presentation unit 30.

(Second light emitting part)
For the second light emitting unit 50, for example, laser light, LED light, or the like can be used. For example, in the case of laser light, the polarization direction is adjusted so as to have a polarization component in a specific direction, and in the case of LED light or the like, a polarization element is arranged in the emission part so as to have a polarization component in a specific direction. In the present embodiment, an LED light source is used as the second light emitting unit 50, and the second polarizing plate 55 is disposed in the emitting unit.

  The 2nd light emission part 50 radiate | emits the light which has a polarization direction in the 2nd polarization direction 33 shown to FIG. Accordingly, the polarization direction of the light emitted from the second light emitting unit 50 through the second polarizing plate 55 is orthogonal to the polarization direction of the light emitted from the first light emitting unit 40 through the first polarizing plate 45. Light emitted from the second light emitting unit 50 through the second polarizing plate 55 can pass through the entire region of the second information presentation unit 30 and the first transmission unit 22 of the first information presentation unit 20.

  FIG. 1B is a diagram illustrating a path of light emitted from the first light emitting unit. As shown in FIG. 1B, the necessary light 40 a is directly emitted from the first light emitting unit 40 to the first information presentation unit 20 and the second information presentation unit 30. On the other hand, the light 40b unnecessary for the information presentation does not contribute to the information presentation because it exits from the side surface. Note that the light 40b unnecessary for presenting information is configured not to go out of the switch device 1 by the bezel 200 shown in FIG. 1B.

  The above description is about the path of light emitted from the first light emitting unit 40, but the same applies to the path of light emitted from the second light emitting unit 50.

(Display of the first display mark part)
When the first light emitting unit 40 is caused to emit light, light having a polarization direction in the first polarization direction 23 is emitted from the first light emitting unit 40 through the first polarizing plate 45. This light is applied to the first information presentation unit 20 and the second information presentation unit 30 as the necessary light described above. Since this necessary light has a polarization direction in the first polarization direction 23, it passes through the entire area of the second transmission unit 32 and the first information presentation unit 20 of the second information presentation unit 30. Accordingly, the first display mark portion 25 is displayed, which is a combination of the common portion 101 and the first region 102 shown in FIG.

When the second light emitting unit 50 emits light, light having a polarization direction in the second polarization direction 33 is emitted from the second light emitting unit 50 through the second polarizing plate 55. This light is applied to the first information presentation unit 20 and the second information presentation unit 30 as the necessary light described above. Since this necessary light has a polarization direction in the second polarization direction 33, it passes through the entire region of the second information presentation unit 30 and the first transmission unit 22 of the first information presentation unit 20. Accordingly, the second display mark portion 35 is displayed, which is a combination of the common portion 101 and the second region 103 shown in FIG. Regions other than the second display mark portion 35 are not displayed as the second non-display mark portion 36 that is a combination of the first region 102, the non-display region 104, and the frame portion 105 shown in FIG.

  Here, the 1st permeation | transmission part 22 shown to Fig.3B (a) is an area | region which sublimated the iodine pigment | dye of a PVA layer by laser irradiation etc., and has disappeared. Thereby, the 1st transmission part 22 does not have a polarization function, but can permeate | transmit light irrespective of a polarization state.

  As shown in FIGS. 3B (a) and 3 (b), the first information presentation unit 20 includes a first polarization unit 21 that does not transmit linearly polarized light polarized in the first polarization direction 24, and a polarization state. 1st transmission part 22 which permeate | transmits light, and is comprised. Accordingly, the first information presentation unit 20 functions as a presentation filter. The shapes of the first polarizing unit 21 and the first transmitting unit 22 can display a figure such as a predetermined mark or character by a combination with a second information presentation unit 30 described later.

(Second information presentation unit 30)
The 2nd information presentation part 30 is also formed with a plate-shaped polarizing plate by the same composition as the 1st information presentation part 20, and functions as a presentation filter. The second information presentation unit 30 is provided in the operation unit 10 so as to partially overlap the first information presentation unit 20, and is irradiated with light having a second polarization direction 34 different from the first polarization direction 24. It is configured as follows. Here, the first polarization direction 24 and the second polarization direction 34 are orthogonal to each other.

  As shown in FIGS. 3B (c) and 3 (d), the second information presentation unit 30 includes a second polarization unit 31 that does not transmit linearly polarized light polarized in the second polarization direction 34, and a polarization state. It has the area | region of the 2nd transmission part 32 which permeate | transmits light, and is comprised. Therefore, the second information presentation unit 30 functions as a presentation filter. The shape of the second polarizing unit 31 and the second transmitting unit 32 can display a figure such as a predetermined mark or character by a combination with the first information presentation unit 20 described above.

(First light emitting part)
For the first light emitting unit 40, for example, laser light, LED light, or the like can be used. For example, in the case of laser light, the polarization direction is adjusted so as to have a polarization component in a specific direction, and in the case of LED light or the like, a polarization element is arranged in the emission part so as to have a polarization component in a specific direction. In the present embodiment, an LED light source is used as the first light emitting unit 40, and the first polarizing plate 45 is disposed in the emitting unit.

  The first light emitting unit 40 emits light having a polarization direction in the first polarization direction 24 shown in FIG. The light emitted from the first light emitting unit 40 through the first polarizing plate 45 can pass through the entire region of the second information presentation unit 30 and the first transmission unit 22 of the first information presentation unit 20.

(Second light emitting part)
For the second light emitting unit 50, for example, laser light, LED light, or the like can be used. For example, in the case of laser light, the polarization direction is adjusted so as to have a polarization component in a specific direction, and in the case of LED light or the like, a polarization element is arranged in the emission part so as to have a polarization component in a specific direction. In the present embodiment, an LED light source is used as the second light emitting unit 50, and the second polarizing plate 55 is disposed in the emitting unit.

  The second light emitting unit 50 emits light having a polarization direction in the second polarization direction 34 shown in FIG. 3B (c) by the second polarizing plate 55. Accordingly, the polarization direction of the light emitted from the second light emitting unit 50 through the second polarizing plate 55 is orthogonal to the polarization direction of the light emitted from the first light emitting unit 40 through the first polarizing plate 45. The light emitted from the second light emitting unit 50 through the second polarizing plate 55 can pass through the entire area of the second transmission unit 32 and the first information presentation unit 20 of the second information presentation unit 30.

  FIG. 1B is a diagram illustrating a path of light emitted from the first light emitting unit. As shown in FIG. 1B, the necessary light 40 a is directly emitted from the first light emitting unit 40 to the first information presentation unit 20 and the second information presentation unit 30. On the other hand, the light 40b unnecessary for the information presentation does not contribute to the information presentation because it exits from the side surface. Note that the light 40b unnecessary for presenting information is configured not to go out of the switch device 1 by the bezel 200 shown in FIG. 1B.

  The above description is about the path of light emitted from the first light emitting unit 40, but the same applies to the path of light emitted from the second light emitting unit 50.

(Display of the first display mark part)
When the first light emitting unit 40 is caused to emit light, light having a polarization direction in the first polarization direction 24 is emitted from the first light emitting unit 40 through the first polarizing plate 45. This light is applied to the first information presentation unit 20 and the second information presentation unit 30 as the necessary light described above. Since this necessary light has a polarization direction in the first polarization direction 24, it passes through the entire region of the second information presentation unit 30 and the first transmission unit 22 of the first information presentation unit 20. Accordingly, the first display mark portion 25 is displayed, which is a combination of the common portion 101 and the first region 102 shown in FIG. The area other than the first display mark part 25 is not displayed as the first non-display mark part 26 including the second area 103, the non-display area 104, and the frame part 105 shown in FIG. It becomes the state of.

(Display of second display mark part)
When the second light emitting unit 50 emits light, light having a polarization direction in the second polarization direction 34 is emitted from the second light emitting unit 50 through the second polarizing plate 55. This light is applied to the first information presentation unit 20 and the second information presentation unit 30 as the necessary light described above. Since this necessary light has a polarization direction in the second polarization direction 34, it passes through the entire area of the second transmission unit 32 and the first information presentation unit 20 of the second information presentation unit 30. Accordingly, the second display mark portion 35 is displayed, which is a combination of the common portion 101 and the second region 103 shown in FIG. Regions other than the second display mark portion 35 are not displayed as the second non-display mark portion 36 that is a combination of the first region 102, the non-display region 104, and the frame portion 105 shown in FIG. It becomes the state of.

(Effect of embodiment)
The embodiment of the present invention has the following effects.
(1) The switch device 1 according to the present embodiment includes an operation unit 10 that switches an operation state of the switch unit 92 mounted on the substrate unit 95, and light that has a first polarization direction provided in the operation unit 10. A first information presentation unit 20 that presents information by irradiation, and a second polarization direction that is provided so as to partially overlap the first information presentation unit 20 in the operation unit 10 and is different from the first polarization direction A second information presentation unit 30 that presents information by being irradiated with light, a first light emitting unit 40 that emits light through a polarizing plate having a first polarization direction, and a second polarization direction. The second light emitting unit 50 that irradiates light through the polarizing plate having the moving unit 300 and the moving mechanism 300 and 310 that moves the operation unit 10 with respect to the substrate unit 95. Extending at least two rods 60, 6 And guide portions 16 and 17 that are formed on a long length, and each of the rod-like portions 60 and 61 are slidably fitted, and the rod-like portions 60 and 61 and the guide portions 16 and 17 are Either one is provided in the operation unit 10 and the other is provided on the substrate unit 95 side. In this Embodiment, the 1st information presentation part 20 and the 2nd information presentation part 30 are provided so that one part may overlap. Since at least a portion overlaps, the first polarized light from the first light emitting unit 40 and the second polarized light from the second light emitting unit 50 cannot be irradiated in a completely spatially separated manner. For this reason, in the present embodiment, the polarization directions (polarization angles) of the first polarized light from the first light emitting unit 40 and the second polarized light from the second light emitting unit 50 are different (for example, orthogonal). Yes. Further, a moving mechanism 300 configured by the rod-shaped portion 60 and the guide portion 16 and a moving mechanism 310 configured by the rod-shaped portion 61 and the guide portion 17 are provided, and emitted from the first light emitting portion 40 and the second light emitting portion 50. There is no wall or the like around the light. Therefore, it is possible to reduce the deterioration of display performance due to the reflection of unnecessary light and the arrival of the light whose polarization state has changed reaching the first information presentation unit 20 or the second information presentation unit 30. . As a result, it is possible to provide a switch device having an operation unit with improved visibility of non-display marks and excellent display switching performance.
(2) In the switch device 1 according to the present embodiment, as shown in FIG. 1B, the periphery of the knob portion 11 of the operation unit 10 is surrounded by a bezel 200, and from the inside of the switch device to the outside. It is said that light does not come out. Thereby, even if there is no wall or the like around the light emitted from the first light emitting unit 40 and the second light emitting unit 50, unnecessary light (40b and the like) does not exit from the inside of the switch device to the outside.
(3) FIG. 6 is a cross-sectional view showing a light path in the case of the prior art. As described above, in the switchable display configuration shown in FIGS. 1, 6, etc., the light from the first light emitting unit 40 and the light from the second light emitting unit 50 are spatially completely separated and irradiated. For this reason, for example, a light separation shielding plate or the like cannot be disposed in the central portion. Therefore, in the conventional configuration as shown in FIG. 6, light (40b, 50b) reflected by the wall 62 of the holder 60 and whose polarization state has changed reaches the first information presentation unit 20 or the second information presentation unit 30. Thus, for example, when the first display mark portion is displayed, the display performance is deteriorated such that the second display mark portion is also displayed. On the other hand, in this Embodiment, since the thing equivalent to the wall part 62 is not provided, only the required light can be irradiated to the 1st information presentation part 20 or the 2nd information presentation part 30. FIG. That is, only the light having the polarization direction in the first polarization direction among the light emitted from the first light emitting unit 40 is irradiated to the first information presentation unit 20. Similarly, of the light emitted from the second light emitting unit 50, only the light having the polarization direction in the second polarization direction is irradiated to the second information presentation unit 30. Thereby, display performance is hardly deteriorated, and improvement in the appearance of non-display marks can be expected.
(4) In the switch device 1 according to the present embodiment, the display mark portion can be switched and displayed on the operation surface 13 of the knob portion 11, so that the display content can be switched according to the content of the on / off operation of the switch device, for example. In addition, since the switchable content display is a high-performance display in which the non-display mark appearance is improved, the operability when the switch device 1 is operated is improved.
(5) The present embodiment can be used as a switch device having a display switching function, and can also be used as a display switching device having no switch function.
