FIG. 1 is an exploded perspective view showing a state in which the indicator lamp according to the first embodiment accommodates a transmitter. FIG. 2 is a front view showing a state in which the indicator lamp of FIG. 1 is mounted on the mounting surface. The indicator light 1 is attached to a mounting surface 4 such as a wall surface to indicate the position of the disaster prevention device. Here, a case where the disaster prevention device is the transmitter 2 will be described as an example. The transmitter 2 is a device that notifies a fire by transmitting a fire signal to a fire receiver (not shown) or the like by pressing a push button portion 22a by a person who discovers a fire. Hereinafter, a case where the position of the transmitter 2 is displayed by an indicator lamp 1 formed so as to surround the outer circumference of the transmitter 2 will be described.

FIG. 3 is a cross-sectional view taken along the line AA of FIG. FIG. 3 shows a cross section of the indicator lamp 1, but only the outer shape of the transmitter 2 is shown, and the internal structure is not shown. In the following description, when the indicator lamp 1 is mounted in the mounting recess 41 formed on the mounting surface 4, the front side of the mounting surface 4 is referred to as the front side, and the back side of the mounting surface 4 is referred to as the back side or the rear side.

The indicator lights 1 shown in FIGS. 1 to 3 have a circular outer shape with the transmitter 2 arranged substantially in the center in the front view. The indicator light 1 includes a light emitting unit 12 that emits light, an indicator light housing 13 that houses the light emitting unit 12, and an indicator light cover 11 that covers the front surface of the light emitting unit 12.

The indicator light housing 13 has an indicator light outer peripheral portion 131 forming an outer peripheral wall and an indicator light back surface portion 133 forming a back wall, and the front surface is open. The indicator lamp outer peripheral portion 131 of the indicator lamp 1 shown in FIG. 1 has a cylindrical shape extending in the front-rear direction. As shown in FIG. 3, the outer peripheral surface of the indicator light outer peripheral portion 131 and the back surface of the indicator light back surface portion 133 face the inner surface of the mounting recess 41, and the front end portion of the indicator light outer peripheral portion 131 is abbreviated as the mounting surface 4. The indicator light 1 is mounted on the mounting surface 4 so as to be flush with each other.

Further, the indicator light housing 13 has a transmitter storage section 132 in which the transmitter 2 is housed inside the indicator light outer peripheral portion 131. As shown in FIGS. 1 and 3, the transmitter accommodating portion 132 has a rib 132a erected on the front surface of the indicator light rear portion 133 and a bottom surface portion forming a bottom surface of a recess formed inside the rib 132a. It has a 132b and a mounting hole 132c provided on the bottom surface 132b. The mounting hole 132c is provided so as to penetrate the indicator lamp back surface portion 133 from the bottom surface portion 132b. The recess and the mounting hole 132c formed by the rib 132a and the bottom surface 132b are formed in a shape corresponding to the outer shape of the transmitter 2. In the example shown in FIGS. 1 to 3, the transmitter 2 is composed of a front side portion having a cylindrical shape and a back side portion having a rectangular parallelepiped shape, the rib 132a of the indicator lamp 1 has an annular shape, and the mounting hole 132c is a square shape. It is formed in a shape.

In the indicator light housing 13, a light emitting portion accommodating portion 134 for accommodating the light emitting portion 12 is formed between the indicator light outer peripheral portion 131 and the transmitter accommodating portion 132. Specifically, the light emitting portion accommodating portion 134 is a space in a groove formed by an inner peripheral surface of the indicator lamp outer peripheral portion 131, an outer peripheral surface of the rib 132a, and a front surface of the indicator lamp back surface portion 133. The light emitting unit storage unit 134 includes a space through which the light emitted from the light emitting unit 12 passes, and the light emitting unit 12 is arranged on the innermost side of the light emitting unit storage unit 134.

The light emitting unit 12 has a light source unit 121 and a liquid crystal unit 122 that emits the light of the light source unit 121. The liquid crystal unit 122 is provided in front of the light source unit 121, and controls the light emitted from the light emitting unit 12. The light emitting unit 12 is installed in the light emitting unit storage unit 134 so that the light source unit 121 and the front surface of the indicator lamp back surface unit 133 face each other. At least a part of the light emitting unit 12 constantly emits light, and is configured so that the position of the disaster prevention device can always be visually recognized by the user.

The light emitting unit 12 may be composed of, for example, a liquid crystal display having a liquid crystal panel as a liquid crystal unit 122 and a backlight for illuminating the liquid crystal panel as a light source unit 121. The backlight is generally composed of one or a plurality of LEDs and a thin plate-shaped light guide plate interposed between the LEDs and the liquid crystal panel, and the light of the LEDs is transmitted to the liquid crystal panel via the light guide plate. Make it incident. In the liquid crystal display, the backlight is arranged in close contact with, for example, the back side of the liquid crystal unit 122. The liquid crystal panel is an image display portion of a liquid crystal display, which is formed by sandwiching a liquid crystal with transparent electrodes or the like. Liquid crystal is generally a substance that has both liquid and solid properties at the same time. The liquid crystal has a property of changing its direction depending on the voltage, and such a property can be used to pass or block the light of the backlight.

The light emitting unit 12 is connected to the control unit 14 (see FIG. 6) and emits light based on the signal from the control unit 14. The light emitting amount and the light emitting pattern of the light emitting unit 12 are controlled by the control unit 14. Specifically, the liquid crystal unit 122 has a plurality of pixels arranged in the vertical direction and the horizontal direction, that is, in the vertical direction and the horizontal direction in FIG. 1, and a light emission pattern is realized by a combination of light emission of each pixel. .. The liquid crystal unit 122 emits the light of the light source unit 121 according to a light emission pattern preset in the control unit 14. The light emission pattern can be set and changed by the operator, and when the indicator light 1 is installed on the mounting surface 4, the operator determines the light emission pattern according to the environment or purpose in which the indicator light 1 is installed. Just do it. The liquid crystal unit 122 is provided with, for example, a red color filter or the like, and is configured to be capable of emitting at least red light. As described above, since the light emitting unit 12 has the liquid crystal unit 122, the light emitting pattern of the light emitting unit 12 can be arbitrarily changed.

In the indicator lights 1 shown in FIGS. 1 to 3, since the transmitter 2 is arranged on the inner peripheral side of the indicator lights 1 in front view, the light emitting unit 12 has a ring shape surrounding the outer circumference of the transmitter 2. The position of the transmitter 2 is configured so that the user can easily see it.

In the light emitting unit 12, since the light of the light source unit 121 is emitted through the liquid crystal unit 122, the light emitted from the light emitting unit 12 can be made into light having good directivity with the traveling direction directed forward. Further, since the light with good directivity is emitted from the light emitting unit 12, the loss of light until the light of the light source unit 121 reaches the front surface of the indicator lamp housing 13 is smaller than that of the conventional indicator lamp. I'm done. Therefore, the light of the light source unit 121 can be used with high efficiency, and a certain amount of light or more can be secured in front of the indicator lamp 1. Since the directivity of light is good on the front surface of the indicator light housing 13 and a certain amount of light can be secured, even when the indicator light cover 11 is provided on the front surface of the indicator light housing 13 to adjust the directivity, the light is emitted. Can be easily controlled.

As shown in FIGS. 1 and 3, the indicator light cover 11 is provided so as to cover the light emitting surface 122a of the liquid crystal unit 122 and protects the liquid crystal unit 122. Specifically, the indicator light cover 11 forms an annular shape having substantially the same shape as the light emitting portion storage portion 134 in which the liquid crystal unit 122 is arranged in a front view, and the light emitting portion storage portion 134 of the indicator light housing 13 has a shape. It has a function of closing the opening on the front side and preventing dust or water from entering the indicator light housing 13 through the opening. The indicator light cover 11 is made of a translucent member that transmits light emitted from the light emitting unit 12. When the indicator light 1 includes the indicator light cover 11, the outline of the indicator light cover 11 is formed by the indicator light cover 11 provided on the front surface of the light emitting unit storage unit 134 of the indicator light housing 13 receiving the light of the light emitting unit 12. It emerges brightly and the visibility of the indicator light 1 is further improved.

Further, the indicator light cover 11 may also have a function of protecting the liquid crystal unit 122 described above and a function of converting the light distribution of the light emitted from the liquid crystal unit 122. In this case, the indicator light cover 11 is composed of an optical element that defines the directionality of the light, and is, for example, a lens that diffuses the light emitted from the liquid crystal unit 122 toward the front or condenses the light in a specific direction. It is composed. Specifically, the indicator light cover 11 may be formed of a convex lens, a concave lens, or the like. In FIG. 3, the broken line arrow indicates the traveling direction of the light transmitted through the indicator light cover 11. In the example shown in FIG. 3, the indicator light cover 11 is composed of a convex lens whose front surface is convex forward, and the light emitted from the liquid crystal unit 122 toward the front is diffused by the indicator light cover 11 and emitted. , The visibility of the indicator light 1 from the side is improved.

FIG. 4 is a cross-sectional view showing a first modification of the indicator lamp according to the first embodiment. In FIG. 4, the broken line arrow indicates the traveling direction of the light transmitted through the indicator light cover 11. In the example shown in FIG. 4, the front surface of the indicator light cover 11 forms a slope portion 11a inclined toward the outer peripheral side and the front side of the indicator light 1. Specifically, the cross section of the right side portion of the indicator light cover 11 and the cross section of the left side portion are symmetrical, and the slope portion 11a is forward as it goes from the transmitter storage portion 132 side to the indicator light outer peripheral portion 131 side. Inclined to. Therefore, according to the indicator light cover 11 shown in FIG. 4, the light emitted from the liquid crystal unit 122 toward the front can be converted into the light inclined toward the outer peripheral side of the indicator light 1, and the indicator light cover Similar to the case where the eleven is configured by the convex lens, the visibility from the side of the indicator lamp 1 is improved.

The cross-sectional shape of the lens constituting the indicator light cover 11 is not particularly limited to that described above, and may be appropriately determined according to the environment or purpose in which the indicator light 1 is installed. Further, the indicator light cover 11 may have, for example, a flat shape with a small protrusion from the mounting surface 4 to avoid a collision with a person or an object. When the indicator light cover 11 is changed from the conventional protruding shape to a flat shape, there is a concern that the visibility may be lowered due to the decrease in the exposed area of the indicator light cover 11. However, as described above, since the indicator lamp 1 is provided with the light emitting unit 12 having the liquid crystal unit 122, the light emitted from the light emitting unit 12 arranged on the back side of the light emitting unit storage unit 134 is lost. It is possible to reach the indicator light cover 11 while suppressing the pressure. Therefore, even when the indicator light cover 11 has a flat shape in the indicator light 1, the decrease in visibility can be compensated for by the brightness. In the example shown in FIGS. 3 and 4, the back surface of the indicator light cover 11 facing the light emitting unit 12 is flat, and the light distribution of light is changed depending on the shape or inclination of the front surface. Alternatively, the light distribution may be converted by a combination of the back surface and the front surface. For example, when the front surface of the indicator light cover 11 is flat and the back surface is appropriately processed to have a function of converting light distribution, the indicator light cover 11 has a flat surface as described above. The same effect as when it is done is obtained.

Further, the positional relationship between the indicator light 1 and the disaster prevention device, the shape of the light emitting unit 12, and the like are not limited to the above cases. The shape of the light emitting unit 12 in front view may be any shape as long as it indicates the position of the disaster prevention device to the user, and may be, for example, a circle or a rectangle. Further, the shapes of the light emitting unit storage unit 134 and the liquid crystal unit 122 may be determined according to the desired shape of the light emitting unit 12. In recent years, it has become easy to mold a liquid crystal into any shape. By forming the light emitting portion 12 with a liquid crystal portion 122 or the like, for example, the above-mentioned molding of a ring-shaped light emitting portion 12 in which the inside of the circular shape is hollowed out is formed. Is also easy.

FIG. 5 is a cross-sectional view showing a second modification of the indicator lamp according to the first embodiment. FIG. 6 is an explanatory diagram illustrating a light emitting pattern of a light emitting unit in a second modification of the indicator lamp according to the first embodiment. The indicator light 1 of the second modification shown in FIGS. 5 and 6 is provided separately from the transmitter 2 and does not have the transmitter storage unit 132. The indicator lamp 1 of the second modification is formed in a circular shape when viewed from the front, the light emitting portion 12 of the indicator lamp 1 has a circular shape, and the light emitting portion accommodating portion 134 has a circular concave portion.

By the way, when the indicator light 1 is installed indoors, the indicator light cover 11 may be omitted because rainwater or the like does not enter the indicator light 1. Up to now, the case where the indicator light cover 11 is composed of a lens to adjust the directivity of light has been described, but when the indicator light cover 11 is not provided, the directivity of light is adjusted to the indicator light housing 13. It can have a function.

Specifically, in the indicator lamp 1 of the second modification shown in FIGS. 5 and 6, as shown in FIG. 5, the front end surface 131b of the indicator lamp outer peripheral portion 131 is formed on the outer peripheral side and the front side of the indicator lamp 1. The slope should be mirror-finished. With such a configuration, a part of the light emitted from the liquid crystal unit 122 and passing through the light emitting unit storage unit 134 can be diffused sideways, and even if the indicator light cover 11 is omitted, the indicator light 1 from the side can be diffused. Visibility can be improved. Further, the inner surface 131a of the indicator lamp outer peripheral portion 131, that is, the inner surface of the recess which is the light emitting portion accommodating portion 134 may also be mirror-finished. Even when the user looks at the indicator lamp 1 from an angle at which the light emitting portion 12 arranged at the back of the light emitting portion storage portion 134 cannot be directly viewed, the inner surface 131a and the front end surface 131b of the mirror-finished outer peripheral portion 131 of the indicator lamp are used. By reflecting the light and diffusing the light, the visibility from the side is improved. As described above, by substituting the function of adjusting the directivity of the light provided in the indicator light cover 11 with the indicator light housing 13, the number of parts of the indicator light 1 can be reduced.

The control unit 14 is composed of a drive circuit including a liquid crystal driver and the like, a CPU (Central Processing Unit), a memory and the like. By controlling the drive of the liquid crystal unit 122, the control unit 14 causes the liquid crystal unit 122 to emit light at a specific position or region, and can realize various light emission patterns. Further, the control unit 14 has an operation unit (not shown), and the position and region of light emission in the liquid crystal unit 122 can be changed via the operation unit. Further, the control unit 14 can have a message property such as guiding to an evacuation port by changing the position and region of light emission in the liquid crystal unit 122 with time. In this way, by using a liquid crystal that can easily change the color of the emitted light, the amount of light, the portion to be emitted, and the like for the light emitting unit 12, the light emitting pattern of the light emitting unit 12 is determined according to the environment or purpose in which the indicator lamp 1 is installed. Can be changed, and the intended directivity can be obtained in the indicator lamp 1.

The control unit 14 is provided in the indicator light 1, for example, behind the light emitting unit 12. The control unit 14 may be arranged anywhere as long as it is connected to the liquid crystal unit 122 so that the drive of the liquid crystal unit 122 can be controlled. For example, the control unit 14 is behind the indicator light rear unit 133 so as not to be directly touched by the user. It may be provided in. Alternatively, only the drive circuit may be installed behind the light source unit 121 in the light emitting unit accommodating unit 134, and a CPU connected to the drive circuit by a signal line or the like may be provided outside the indicator lamp housing 13.

Hereinafter, a light emission pattern, which is a variation of the light emission method of the light emitting unit 12, will be described. For example, the light emitting unit 12 may emit light only at a portion close to the disaster prevention device. Further, for example, the light emitting unit 12 is divided into three or more regions from the far side from the disaster prevention device, and the light is emitted in order from the far area, or the entire area is made to emit light and then switched to non-light emission in order from the disaster prevention device and the far area. The light emitting area may be reduced. In this way, the position of the disaster prevention device with respect to the indicator lamp 1 can be displayed by sequentially changing the light emitting region.

In the second modification shown in FIG. 6, the transmitter 2 which is a disaster prevention device is installed on the mounting surface 4 on the right side of the indicator light 1. In this case, for example, in the liquid crystal unit 122, the voltages applied to the first region 122b on the right side of the virtual line and the second region 122c on the left side are made different, and the first region 122b emits the light of the light source unit 121. , The liquid crystal unit 122 is controlled so that the second region 122c blocks light. With this configuration, in the light emitting unit 12, the position of the transmitter 2 is displayed by the first region 122b close to the transmitter 2, and the light emitting unit 12 is used as compared with the case where the entire liquid crystal unit 122 is driven. The power can be reduced. Further, in the second modification in which the light emitting unit 12 is circular in the front view of the indicator light 1, when the right half of the light emitting unit 12 is made to emit light, the right side of the indicator light 1, that is, the disaster prevention device, may be affected by the half-moon shape. The line of sight of the user can be guided to the position.

Further, the light emission pattern may be determined not only according to the positional relationship between the disaster prevention device and the indicator light 1, but also according to the environment in which the indicator light 1 is installed. For example, when the indicator light 1 is installed on the mounting surface 4 and the passage is not provided in a specific direction, the light emitting unit 12 is more than a portion closer to the specific direction in which the passage is not provided. The amount of light of the liquid crystal unit 122 may be controlled so that the portion of the liquid crystal unit 122 emits bright light.

As described above, in the first embodiment, since the indicator lamp 1 includes the light emitting unit 12 having the liquid crystal unit 122, the directivity of the light emitting unit 12 can be arbitrarily changed and installed. Visibility can be ensured regardless of the location.

Further, the indicator light 1 further includes an indicator light cover 11 that protects the liquid crystal unit 122, and the indicator light cover 11 is composed of a lens that converts light distribution. As a result, the indicator light cover 11 can have both a function of protecting the liquid crystal unit 122 and a function of adjusting the directivity of light.

Further, the liquid crystal unit 122 of the indicator lamp 1 has an annular shape. As a result, the disaster prevention equipment can be stored on the inner peripheral side of the indicator light 1 and the position of the disaster prevention equipment can be displayed. Further, since the light emitting unit 12 is composed of the liquid crystal unit 122 and the like, it can be easily molded even when the indicator lamp 1 and the disaster prevention device are integrally formed.

Further, the touch panel 222 of the push button 22 is provided at a position corresponding to the push portion 28 of the substrate 23 so as to cover the light source portion 221 provided on the front surface of the substrate 23. The touch panel 222 may be provided at least in a range that overlaps with the shaft portion 282 of the push-in portion 28 in front view. Further, the touch panel 222 is separated from the rear end portion of the shaft portion 282 when the pushing portion 28 is not pushed.

The outer peripheral portion 26 of the main body of the housing further has a partition wall 263 and a first guide portion 264 for restricting the movement of the push portion 28 in the push button storage portion 262. The partition wall 263 partitions the storage space 262a formed in the push button storage portion 262 into a front side and a back side, and is composed of a member that does not transmit light. The outer peripheral end of the partition wall 263 is connected to the inner surface of the push button storage portion 262, and the partition wall 263 is formed with a shaft hole 263a into which the shaft portion 282 of the push portion 28 is inserted. Further, as shown in FIG. 9, a cylindrical second guide portion 263b extending rearward is formed at the edge portion of the shaft hole 263a on the back surface of the partition wall 263. The second guide portion 263b guides the shaft portion 282 to move along the second guide portion 263b when the pushing portion 28 is pushed backward. The first guide portion 264 is composed of, for example, a pair of plate-shaped members provided along the inner surfaces of the left side and the right side of the push button storage portion 262 in the storage space 262a in front of the partition wall 263. .. When the pushing portion 28 is pushed backward, the first guide portion 264 guides the front portion 281 of the pushing portion 28 to move along the first guide portion 264. By providing the first guide portion 264 and the second guide portion 263b, the push-in portion 28 can be smoothly moved backward in the housing.

Further, the transmitter main body 20 is provided with a cushioning material 29 that cushions the impact applied to the touch panel 222 when the pushing portion 28 is pressed. The cushioning material 29 is composed of, for example, an elastic member. In the example shown in FIGS. 7 and 8, the cushioning material 29 is composed of a spring wound around the shaft portion 282 of the pushing portion 28. When the front end portion 281 of the push-in portion 28 is pushed, the cushioning material 29 has a front end portion in contact with the back surface of the front portion 281 of the push-in portion 28, and the back end portion is a shaft in the front surface of the partition wall 263. It is arranged so as to come into contact with a portion around the hole 263a.

By providing the cushioning material 29, it is possible to prevent a force pushed by a person from being directly applied to the touch panel 222 when the pushing portion 28 is pushed, and to prevent the liquid crystal portion and the detection sensor of the touch panel 222 from being damaged. Can be done. The structure of the cushioning material 29 is not limited to this.

The substrate 23 has a circuit for outputting a fire signal and a drive circuit for driving the liquid crystal unit of the light source unit 221 and the touch panel 222. A detection signal indicating that the push button 22 is pressed is input to the substrate 23 from the detection sensor of the touch panel 222. Further, the board 23 outputs a fire signal when the detection signal is input. Further, the substrate 23 controls the light source unit 221 and the touch panel 222 so that the push button 22 emits light when a detection signal is input.

Here, it is assumed that the push button 22 does not normally emit light, and a configuration in which the push button 22 emits light when it is detected that the push button 22 is pressed will be illustrated. With such a configuration, it is possible to notify the person who has pushed the push-in portion 28 that the push button 22 at the back of the push-in portion 28 has been pressed.

The timing of causing the push button 22 to emit light is not limited to such a configuration. For example, it is assumed that the push button 22 is constantly emitting light, and the presence of the push button 22 may be configured to always be displayed to the user. Alternatively, the light emission pattern may be changed depending on whether the push button 22 is pressed or not.

Next, an example of the operation of the transmitter 2 when the push button 22 of the transmitter 2 is pressed in the event of a fire will be described with reference to FIGS. 7 to 9. When the pushing portion 28 is pushed through the first opening 211a provided in the cover front portion 211 of the transmitter 2, the pushing portion 28 moves to the back along the first guide portion 264 and the second guide portion 263b. As it moves, the touch panel 222 is pushed by the rear end of the shaft portion 282. At this time, the cushioning material 29 alleviates the impact applied to the touch panel 222. When the touch panel 222 is pressed by the shaft portion 282, a certain force or more is applied to the detection sensor of the touch panel 222, the detection sensor detects that the push button 22 is pressed, and the detection signal is output to the substrate 23. When the detection signal is input to the board 23 from the detection sensor, the board 23 determines that the push button 22 has been pressed, outputs a fire signal, and outputs a drive signal to the light source unit 221 and the touch panel 222. The fire signal output from the board 23 is transmitted from the transmitter 2 to a receiver or the like (not shown) to notify the fire. The light source unit 221 and the touch panel 222 are driven by a drive signal from the substrate 23, and the push button 22 arranged on the back side of the storage space 262a emits light. At this time, the light emitted from the push button 22 is guided to the front surface portion 281 of the push-in portion 28 by the shaft portion 282 inserted into the shaft hole 263a of the partition wall 263 in the push-in portion 28. In the region outside the shaft portion 282, the light emitted from the push button 22 is blocked by the partition wall 263.

As described above, in the second embodiment, since the transmitter 2 includes the push button 22 including the liquid crystal unit, the directivity of the light of the push button 22 can be arbitrarily changed and installed. Visibility can be ensured regardless of the location.

Further, the transmitter 2 includes a push-in portion 28 and a cushioning material 29 that cushions the impact applied to the touch panel 222 when the push-in portion 28 is pressed. As a result, even when the directivity of light can be changed by the touch panel 222 of the push button 22, the impact applied to the touch panel 222 when the push button 22 is pressed can be alleviated, and the light source unit 221 and the touch panel 222 can be moved. It is possible to avoid damage to the push button 22 to be held.

The embodiment of the present invention is not limited to the above embodiment, and various modifications can be made. For example, in the second embodiment, the configuration of the transmitter 2 alone has been described, but the above-mentioned indicator light is attached to the indicator light integrated transmitter 3 (see FIGS. 1 to 4) in which the transmitter and the indicator light are integrally configured. At least one of 1 and transmitter 2 may be applied. Further, at least one of the indicator light 1 and the transmitter 2 may be applied to a device such as an emergency alarm device.

Further, in the indicator light integrated transmitter 3, the liquid crystal unit 122 of the indicator light 1 and the liquid crystal unit of the touch panel 222 of the transmitter 2 may be formed in succession. For example, when the indicator light integrated transmitter 3 has a circular shape when viewed from the front and the liquid crystal portion 122 of the indicator light 1 has a ring shape (see FIGS. 1 to 3), the shape of the liquid crystal portion 122 is changed. , It is not an annular shape but a disk shape, and the light emitting portion storage portion 134 and the push button storage portion 262 are continuous spaces. A detection sensor for the push button 22 is provided at a portion of the liquid crystal unit 122 that is continuously formed and that faces the first opening 211a of the transmitter 2. In this case, a light-shielding plate is provided in a region of the liquid crystal unit 122 that is continuously formed and is not intended to emit light, for example, a region that overlaps with the transmitter 2 in the front view and is excluded from the region that overlaps with the push button 22. It may be. Alternatively, instead of providing the light-shielding plate, the control unit 14 may make the region non-emission. According to such a configuration, the shapes of the liquid crystal portion 122 of the indicator lamp 1 and the transmitter 2 can be simplified, and the molding becomes easy. Further, in the transmitter 3 with integrated indicator light, the push-in portion 28, the partition wall 263, the first guide portion 264, and the like are omitted, and the positions of the light source portion 221 and the liquid crystal portion of the transmitter 2 are located in the indicator lamp 1 in the depth direction. It may be configured to coincide with the positions of the light source unit 121 and the liquid crystal unit 122. In this case, the detection sensor of the push button 22 can be directly pressed by a person, the number of parts can be reduced, and the depth dimension of the indicator light integrated transmitter 3 can be reduced. Further, the indicator light integrated transmitter 3 of the first embodiment has a configuration in which a transmitter 2 having a housing different from the indicator light housing 13 is housed inside the indicator light housing 13 of the indicator light 1. .. However, the housing of the indicator light 1 and the housing of the disaster prevention device such as the transmitter 2 may be integrally configured. Further, in the second embodiment, the case where the detection sensor is arranged in front of the liquid crystal portion in the touch panel 222 has been described, but it may be arranged behind the liquid crystal portion, and is appropriately arranged according to the detection method of the detection sensor and the like. do it.
