Description

Technical Field

[0001] The present invention relates to an indicator light integrated transmitter having a light source unit.

Background Art

[0002] An indicator light has a light source unit such as an LED (Light Emitting Diode), and emits light to indicate the position of a disaster prevention device installed near the indicator light. A transmitter has a push button that can be pressed by a person, and outputs a fire signal when the push button is pressed. There is a type in which a transmitter is attached to the inner peripheral side of an indicator light to form an indicator light integrated transmitter (transmitter with an indicator light) (see, for example, Patent Document 1). In the transmitter with an indicator light disclosed in Patent Document 1, the transmitter on the inner peripheral side includes a translucent push button (hereinafter also referred to as a push-in part) that is pushed by a person and moves to an operation position on the back side, and a circuit block including a switch and an LED. When the push-in part moves to the operation position, the switch of the circuit block is turned on, the LED lights up, and the light of the LED is output forward through the push-in part. Further, in the transmitter with an indicator light disclosed in Patent Document 1, the indicator light on the outer peripheral side includes a light source unit, a light emitting part provided on the front surface of the casing of the indicator light, and a light guide member that takes in the output light of the light source unit and guides it to the light emitting part. This light guide member is composed of a molded product of a transparent resin such as an acrylic resin, and the light emitting part is made to emit light through the light guide member.

Summary of the Invention

Problems to be Solved by the Invention

[0004] However, in the transmitter portion of the transmitter with an indicator light disclosed in Patent Document 1, since the light of the LED is output forward through the translucent pushing portion, even if the light emission amount of the LED can be increased or decreased, the directivity of the light of the pushing portion is determined by the shape and arrangement of the pushing portion, and depending on the location where the pushing portion is installed, the visibility of the pushing portion from a passage where people pass may be reduced. Also, in the indicator light portion, since the entire light-emitting portion provided on the front surface of the casing is caused to emit light via the light guide member, even if the light emission amount of the light source portion can be increased or decreased, the directivity of the light of the indicator light is determined by the shape and arrangement of the components constituting the indicator light, and depending on the location where the indicator light is installed, the visibility from a passage where people pass may be reduced. Further, in the transmitter with an indicator light disclosed in Patent Document 1, since the structures for causing the pushing portion and the indicator light to emit light are separated, it is difficult to reduce the number of parts.

[0005] The present invention has been made to solve the above-described problems, and an object thereof is to provide an indicator light integrated transmitter in which the number of parts can be reduced and the visibility is improved.

Means for Solving the Problems

[0006] The indicator light integrated transmitter of the present invention is an indicator light integrated transmitter including an indicator light that has a light-emitting portion and is constantly lit, and a transmitter that has a push button and transmits a fire signal when the push button is pressed, wherein the light-emitting portion has a first light source portion and a first liquid crystal portion that emits the light of the first light source portion, the push button has a second light source portion and a second liquid crystal portion that emits the light of the second light source portion, and the first liquid crystal portion of the light-emitting portion and the second liquid crystal portion of the push button are part of a continuously formed liquid crystal portion. Furthermore, it is provided with a control unit that controls non-emission of a region excluding a region overlapping with a push button among regions overlapping with a transmitter in a liquid crystal part formed continuously 。 In addition, the display lamp integrated transmitter of the present invention has a light emitting part, a display lamp that always lights up, and a transmitter that has a push button and transmits a fire signal when the push button is pressed. The transmitter has a pushing part that is pushed by a person to press the push button, and a member provided with an opening where the pushing part is disposed. The light emitting part has a first light source part and a first liquid crystal part that emits light from the first light source part. The push button has a second light source part, a second liquid crystal part that emits light from the second light source part, and a detection sensor that detects that the pushing part has been pushed. The pushing part is composed of a light-transmitting member. The first liquid crystal part of the light emitting part and the second liquid crystal part of the push button are part of a continuous liquid crystal part.

Advantages of the Invention

[0007] According to the present invention, by providing the display lamp with a light emitting part having a first liquid crystal part and the transmitter with a push button including a second liquid crystal part, the directivity of the light of the light emitting part and the push button can be arbitrarily changed, and the visibility can be improved regardless of the installation location or the like. At the same time, by using a continuous liquid crystal part for the transmitter and the display lamp, the number of parts can be reduced.

Mode for Carrying Out the Invention

[0009] Embodiment 1. The indicating lamp according to Embodiment 1 will be described with reference to the drawings. FIG. 1 is an exploded perspective view showing a state in which the indicating lamp according to Embodiment 1 houses the transmitter. FIG. 2 is a front view showing a state in which the indicating lamp of FIG. 1 is attached to the attachment surface. The indicating lamp 1 is attached to an attachment surface 4 such as a wall surface and indicates the position of the disaster prevention device. Here, the case where the disaster prevention device is the transmitter 2 will be described as an example. The transmitter 2 is a device that transmits a fire signal to a fire receiver (not shown) or the like when a person who has discovered a fire presses the push button portion 22a to report a fire. Hereinafter, the case where the position of the transmitter 2 is indicated by the indicating lamp 1 formed so as to surround the outer periphery of the transmitter 2 will be described.

[0010] FIG. 3 is a cross-sectional view taken along the line A-A of FIG. 2. FIG. 3 shows a cross-section of the indicating lamp 1, but only the outer shape of the transmitter 2 is shown, and the internal structure is not shown. In the following description, with the indicating lamp 1 attached to the attachment recess 41 formed in the attachment surface 4, the front side of the attachment surface 4 is referred to as the front, and the back side of the attachment surface 4 is referred to as the back or the rear.

[0011] The indicating lamp 1 shown in FIGS. 1 to 3 has the transmitter 2 disposed substantially at the center in a front view and has a circular outer shape. The indicating lamp 1 includes a light emitting portion 12 that emits light, an indicating lamp housing 13 that houses the light emitting portion 12, and an indicating lamp cover 11 that covers the front surface of the light emitting portion 12.

[0012] The display lamp housing 13 has a display lamp outer peripheral portion 131 that constitutes the outer peripheral wall and a display lamp rear surface portion 133 that constitutes the rear wall, and the front is open. The display lamp outer peripheral portion 131 of the display 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 display lamp outer peripheral portion 131 and the rear surface of the display lamp rear surface portion 133 face the inner surface of the mounting recess 41, and the display lamp 1 is attached to the mounting surface 4 such that the front end portion of the display lamp outer peripheral portion 131 is substantially flush with the mounting surface 4.

[0013] Also, the display lamp housing 13 has a transmitter housing portion 132 inside the display lamp outer peripheral portion 131 for housing the transmitter 2. As shown in FIGS. 1 and 3, the transmitter housing portion 132 has a rib 132a erected on the front surface of the display lamp rear surface portion 133, a bottom surface portion 132b that constitutes the bottom surface of the recess formed inside the rib 132a, and a mounting hole 132c provided in the bottom surface portion 132b. The mounting hole 132c is provided so as to penetrate the display lamp rear 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 portion 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 cylindrical front portion and a rectangular parallelepiped rear portion, the rib 132a of the display lamp 1 has an annular shape, and the mounting hole 132c is formed in a square shape.

[0014] In the display lamp housing 13, a light emitting portion housing portion 134 for housing the light emitting portion 12 is formed between the display lamp outer peripheral portion 131 and the transmitter housing portion 132. Specifically, the light emitting portion housing portion 134 is a space in the groove formed by the inner peripheral surface of the display lamp outer peripheral portion 131, the outer peripheral surface of the rib 132a, and the front surface of the display lamp rear surface portion 133. The light emitting portion housing portion 134 includes a space through which the light emitted from the light emitting portion 12 passes, and the light emitting portion 12 is disposed at the innermost side of the light emitting portion housing portion 134.

[0015] The light-emitting unit 12 includes a light source unit 121 and a liquid crystal unit 122 that emits the light from 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 housing portion 134 such that the light source unit 121 and the front surface of the display lamp back surface portion 133 face each other. At least a part of the light-emitting unit 12 emits light constantly, and is configured such that the position of the disaster prevention device can always be visually recognized by the user.

[0016] The light-emitting unit 12 may be configured, for example, as a liquid crystal display including a liquid crystal panel as the liquid crystal unit 122 and a backlight that illuminates the liquid crystal panel as the light source unit 121. A backlight generally includes 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 made to enter the liquid crystal panel through the light guide plate. In a liquid crystal display, the backlight is disposed, for example, in close contact with the back side of the liquid crystal unit 122. A liquid crystal panel is an image display portion of a liquid crystal display configured by sandwiching liquid crystal with transparent electrodes or the like. Liquid crystal generally refers to a substance that has the properties of both a liquid and a solid at the same time. Liquid crystal has the property of changing its orientation depending on voltage, and by utilizing such a property, the light of the backlight can be passed through or blocked.

[0017] The light emitting portion 12 is connected to the control portion 14 (see FIG. 6) and emits light based on a signal from the control portion 14. The light emission amount and light emission pattern of the light emitting portion 12 are controlled by the control portion 14. Specifically, the liquid crystal portion 122 has a plurality of pixels arranged in the vertical direction and the horizontal direction, that is, the up-down direction and the left-right direction in FIG. 1, and a light emission pattern is realized by the combination of the light emissions of the respective pixels. The liquid crystal portion 122 emits the light of the light source portion 121 according to a preset light emission pattern in the control portion 14. The light emission pattern can be set and changed by the operator, and the operator may determine the light emission pattern according to the environment or purpose where the display lamp 1 is installed when the display lamp 1 is installed on the mounting surface 4. The liquid crystal portion 122 is provided with, for example, a red color filter and is configured to be able to emit at least red light. Thus, since the light emitting portion 12 has the liquid crystal portion 122, the light emission pattern of the light emitting portion 12 can be arbitrarily changed.

[0018] In the display lamp 1 shown in FIGS. 1 to 3, in a front view, since the transmitter 2 is arranged on the inner peripheral side of the display lamp 1, the light emitting portion 12 is formed in an annular shape surrounding the outer periphery of the transmitter 2, and is configured so that the position of the transmitter 2 can be easily visually recognized by the user.

[0019] In the light emitting portion 12, since the light of the light source portion 121 is emitted through the liquid crystal portion 122, the light emitted from the light emitting portion 12 can be made into light with good directivity whose traveling direction is forward. Further, since light with good directivity is emitted from the light emitting portion 12, compared with a conventional display lamp, the light loss until the light of the light source portion 121 reaches the front surface of the display lamp housing 13 can be reduced. Therefore, the light of the light source portion 121 can be used with high efficiency, and a light amount of a certain level or more can be ensured on the front surface of the display lamp 1. Since the light has good directivity and a light amount of a certain level or more can be ensured on the front surface of the display lamp housing 13, even when the display lamp cover 11 is provided on the front surface of the display lamp housing 13 to adjust the directivity, the light can be easily controlled.

[0020] The display lamp cover 11 is provided to cover the light-emitting surface 122a of the liquid crystal unit 122 as shown in FIGS. 1 and 3, and protects the liquid crystal unit 122. Specifically, the display lamp cover 11 has an annular shape substantially the same as that of the light-emitting unit housing portion 134 in which the liquid crystal unit 122 is disposed when viewed from the front, closes the opening on the front side of the light-emitting unit housing portion 134 of the display lamp housing 13, and has a function of preventing dust or water from entering the display lamp housing 13 through the opening. The display lamp cover 11 is made of a light-transmitting member that transmits the light emitted from the light-emitting unit 12. When the display lamp 1 includes the display lamp cover 11, the display lamp cover 11 provided on the front surface of the light-emitting unit housing portion 134 of the display lamp housing 13 receives the light of the light-emitting unit 12, so that the contour of the display lamp cover 11 becomes brightly prominent, and the visibility of the display lamp 1 is further improved.

[0021] Further, the display lamp cover 11 may also have the function of protecting the above-described liquid crystal unit 122 and the function of converting the light distribution of the light emitted from the liquid crystal unit 122. In this case, the display lamp cover 11 is composed of an optical element that defines the directionality of light. For example, it is composed of a lens that diffuses the light emitted from the liquid crystal unit 122 forward or condenses the light in a specific direction. Specifically, the display lamp cover 11 is preferably composed 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 display lamp cover 11. In the example shown in FIG. 3, the display lamp cover 11 is composed of a convex lens with a convex front surface, and the light emitted from the liquid crystal unit 122 forward is diffused by the display lamp cover 11 and emitted, so that the visibility from the side of the display lamp 1 is improved.

[0022] FIG. 4 is a cross-sectional view showing a first modification of the display lamp according to Embodiment 1. In FIG. 4, the dashed arrow represents the traveling direction of the light transmitted through the display lamp cover 11. In the example shown in FIG. 4, the front surface of the display lamp cover 11 forms a slanted surface portion 11a that is inclined toward the outer peripheral side and the front side of the display lamp 1. Specifically, the cross-section of the right side portion of the display lamp cover 11 and the cross-section of the left side portion are symmetric, and the slanted surface portion 11a is inclined forward as it goes from the transmitter housing portion 132 side toward the display lamp outer peripheral portion 131 side. Therefore, according to the display lamp cover 11 shown in FIG. 4, the light emitted forward from the liquid crystal portion 122 can be converted into light inclined toward the outer peripheral side of the display lamp 1, and the visibility from the side of the display lamp 1 is improved, similar to the case where the display lamp cover 11 is configured by a convex lens.

[0023] Note that the cross-sectional shape of the lens constituting the display lamp cover 11 is not particularly limited to the one described above, and it may be appropriately determined according to the environment or purpose where the display lamp 1 is installed. Also, the display lamp cover 11 may have, for example, a flat shape with a reduced protrusion from the mounting surface 4 so as to avoid collision with people or objects. When the display lamp cover 11 is changed from the conventional protruding shape to a flat shape, there is a concern about a decrease in visibility due to a reduction in the exposed area of the display lamp cover 11. However, as described above, since the display lamp 1 includes the light emitting portion 12 having the liquid crystal portion 122, the light emitted from the light emitting portion 12 disposed on the back side of the light emitting portion housing portion 134 can reach the display lamp cover 11 while suppressing light loss. Therefore, even when the display lamp cover 11 has a flat shape in the display lamp 1, the decrease in visibility can be compensated for by the brightness. In the examples shown in FIGS. 3 and 4, the back surface of the display lamp cover 11 facing the light emitting portion 12 is flat, and the light distribution is converted by the shape or inclination of the front surface. However, the light distribution may be converted by the back surface or a combination of the back surface and the front surface. For example, when the front surface of the display lamp cover 11 is flat and the back surface is appropriately processed to have a function of converting the light distribution, in the display lamp cover 11, although the surface has a flat shape, the same effect as the above-described case can be obtained.

[0024] In addition, the positional relationship between the indicator light 1 and the disaster prevention device, the shape of the light emitting part 12, etc. are not limited to the above-described cases. The shape of the light emitting part 12 in the front view may be any shape that indicates the position of the disaster prevention device to the user, and may be, for example, circular or rectangular. Also, the shapes of the light emitting part housing part 134 and the liquid crystal part 122 may be determined according to the desired shape of the light emitting part 12. In recent years, it has become easy to mold liquid crystal into any shape, and by configuring the light emitting part 12 with the liquid crystal part 122 or the like, for example, it also becomes easy to mold the light emitting part 12 having an annular shape with a circular shape hollowed out inside as described above.

[0025] FIG. 5 is a cross-sectional view showing a second modification of the indicator light according to Embodiment 1. FIG. 6 is an explanatory diagram for explaining the light emission pattern of the light emitting part in the second modification of the indicator light according to Embodiment 1. 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 a transmitter housing part 132. The indicator light 1 of the second modification is formed in a circular shape in the front view, the light emitting part 12 of the indicator light 1 has a circular shape, and the light emitting part housing part 134 is a circular recess.

[0026] By the way, when the indicator light 1 is installed indoors, since rainwater or the like does not enter the indicator light 1, the indicator light cover 11 may be omitted. So far, the case where the indicator light cover 11 is configured by a lens to adjust the directivity of light has been described. However, when the indicator light cover 11 is not provided, the indicator light housing 13 can be provided with a function of adjusting the directivity of light.

[0027] Specifically, in the indicator lamp 1 of the second modification shown in FIGS. 5 and 6, as shown in FIG. 5, the front end face 131b of the outer peripheral portion 131 of the indicator lamp is inclined toward the outer peripheral side and the front side of the indicator lamp 1 and is formed into a mirror-finished inclined surface. With such a configuration, a part of the light emitted from the liquid crystal portion 122 and passing through the light-emitting portion housing portion 134 can be diffused laterally, and the visibility of the indicator lamp 1 from the side can be improved even when the indicator lamp cover 11 is omitted. Further, the inner surface 131a of the outer peripheral portion 131 of the indicator lamp, that is, the inner side surface of the concave portion which is the light-emitting portion housing portion 134, may also be mirror-finished. Even when the user views the indicator lamp 1 at an angle where the light-emitting portion 12 disposed at the back of the light-emitting portion housing portion 134 cannot be directly seen, the light is reflected by the inner surface 131a and the front end face 131b of the outer peripheral portion 131 of the indicator lamp with mirror finish and the light is diffused, thereby improving the visibility from the side. In this way, by substituting the function of adjusting the directivity of the light provided by the indicator lamp cover 11 with the indicator lamp housing 13, the number of parts of the indicator lamp 1 can be reduced.

[0028] The control unit 14 is composed of a drive circuit including a liquid crystal driver or the like, a CPU (Central Processing Unit), a memory, and the like. The control unit 14 controls the driving of the liquid crystal unit 122, so that a specific position or region in the liquid crystal unit 122 emits light, and various light emission patterns can be realized. Further, the control unit 14 has an operation unit (not shown), and the position and region where the liquid crystal unit 122 emits light can be changed via the operation unit. Further, the control unit 14 can make the position and region where the liquid crystal unit 122 emits light change over time, and can have a message property such as guiding to an evacuation exit. In this way, by using a liquid crystal that can easily change the color, light amount, and the portion where light is emitted of the emitted light in the light-emitting portion 12, the light emission pattern of the light-emitting portion 12 can be changed according to the environment or purpose where the indicator lamp 1 is installed, and the intended directivity can be obtained in the indicator lamp 1.

[0029] The control unit 14 is provided, for example, behind the light-emitting unit 12 in the indicator light 1. Note that the control unit 14 may be disposed anywhere as long as it is connected to the liquid crystal unit 122 so as to be able to control the driving of the liquid crystal unit 122. For example, it may be provided behind the back surface portion 133 of the indicator light so that it cannot be directly touched by the user. Alternatively, only the drive circuit may be installed behind the light source unit 121 in the light-emitting unit housing portion 134, and the CPU connected to the drive circuit by a signal line or the like may be provided outside the indicator light housing 13.

[0030] Hereinafter, a light-emitting pattern, which is a variation of the lighting method of the light-emitting unit 12, will be described. For example, only a portion of the light-emitting unit 12 close to the disaster prevention device may be lit. Also, for example, the light-emitting unit 12 may be divided into three or more regions starting from the side farther from the disaster prevention device, and the regions may be lit in order from the farthest region, or after all regions are lit, the regions may be sequentially changed to non-light-emitting starting from the region farthest from the disaster prevention device to reduce the light-emitting area. In this way, the position of the disaster prevention device with respect to the indicator light 1 can also be indicated by sequentially changing the light-emitting regions.

[0031] In the second modification shown in FIG. 6, a transmitter 2, which is a disaster prevention device, is installed on the mounting surface 4 to the right of the indicator light 1. In this case, for example, different voltages are applied to the first region 122b on the right side of the virtual line and the second region 122c on the left side in the liquid crystal unit 122, and the liquid crystal unit 122 is controlled so that the first region 122b emits the light of the light source unit 121 and the second region 122c blocks the light. With this configuration, in the light-emitting unit 12, the position of the transmitter 2 is indicated by the first region 122b close to the transmitter 2, and the power used for the light-emitting unit 12 can be reduced as compared with the case where the entire liquid crystal unit 122 is driven. Further, in the second modification in which the light-emitting unit 12 forms a circular shape when viewed from the front of the indicator light 1, when the right half of the light-emitting unit 12 emits light, the semi-circular shape can also guide the user's line of sight to the right side of the indicator light 1, that is, the position of the disaster prevention device.

[0032] In addition to the positional relationship between the disaster prevention device and the indicator light 1, the light emission pattern may be determined according to the environment in which the indicator light 1 is installed. For example, when there is no passage provided in a specific direction in the state where the indicator light 1 is installed on the mounting surface 4, in the light emitting unit 12, the light amount of the liquid crystal unit 122 may be controlled so that other parts emit light brighter than the parts closer to the specific direction where no passage is provided.

[0033] As described above, in the first embodiment, since the indicator light 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 visibility can be ensured regardless of the installation location or the like.

[0034] 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 the light distribution of light. Thereby, the indicator light cover 11 can have both the function of protecting the liquid crystal unit 122 and the function of adjusting the directivity of light.

[0035] The liquid crystal unit 122 of the indicator light 1 has an annular shape. Thereby, a configuration is adopted in which the disaster prevention device is housed on the inner peripheral side of the indicator light 1, and the position of the disaster prevention device can be indicated. 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 light 1 and the disaster prevention device are integrally configured.

[0036] Second Embodiment. The transmitter according to the second embodiment will be described with reference to the drawings. FIG. 7 is an exploded perspective view showing the transmitter according to the second embodiment. The transmitter 2 is attached to a mounting surface 4 such as a wall surface and is a device for reporting a fire. The transmitter 2 has a push button 22 including a light source unit 221 and a touch panel 222. When a person who has discovered a fire presses the push button 22 through a pressing portion 28, a fire signal is transmitted to a fire receiver (not shown) or the like. In the second embodiment, the push button 22 having the light source unit 221 corresponds to the light emitting unit in the first embodiment.

[0037] FIG. 8 is a front view showing the transmitter according to Embodiment 2. FIG. 9 is a cross-sectional view taken along the line B-B of FIG. 8. The transmitter 2 of Embodiment 2 will be described with reference to FIGS. 7 to 9. In the following description, with the transmitter 2 attached to the attachment recess 42 formed in the attachment surface 4, the front side of the attachment surface 4 is referred to as the front, and the back side and the rear side of the attachment surface 4 are referred to as the back.

[0038] As shown in FIG. 7, the transmitter 2 has a transmitter body 20 and a transmitter cover 21 that covers the front surface of the transmitter body 20. The transmitter cover 21 has, for example, a circular shape in a front view as shown in FIG. 8. As shown in FIGS. 7 and 8, the transmitter body 20 includes a housing with an open front surface, a push button 22 that emits light, a push-in portion 28 that is pushed by a person, a substrate 23 on which a control circuit is mounted, and the like. The housing is composed of a main body outer peripheral portion 26 that constitutes the outer peripheral portion and a main body back surface portion 27 that constitutes the back surface.

[0039] The main body outer peripheral portion 26 of the housing has a circular cover attachment portion 261 to which the transmitter cover 21 is attached, a cylindrical push button storage portion 262 formed behind the cover attachment portion 261, and the like. The push button 22 is stored in the push button storage portion 262. In the push button storage portion 262, the push-in portion 28 is disposed in front of the push button 22, and the substrate 23 is disposed behind the push button 22. Further, a recovery switch 24 and a telephone jack 25 are provided above the push button storage portion 262. The recovery switch 24 is a switch for returning the transmitter 2 from the operating state to the original state. The main body back surface portion 27 is attached to the main body outer peripheral portion 26 where the push-in portion 28, the push button 22, and the substrate 23 are installed so as to cover the back surface of the substrate 23.

[0040] The push-in portion 28 is composed of, for example, a front surface portion 281 having a square shape in a front view and a shaft portion 282 extending rearward from the center of the back surface of the front surface portion 281. When the push-in portion 28 is pushed by a person, it pushes the push button 22 disposed rearward in the housing. The push-in portion 28 is made of a light-transmitting member and transmits the light emitted from the push button 22.

[0041] The transmitter cover 21 is composed of a circular cover front portion 211, a cylindrical flange portion 212 provided so as to extend rearward from the outer peripheral end of the cover front portion 211, and the like. A first opening 211a for exposing the front portion 281 of the pushing portion 28 disposed in the housing of the transmitter main body 20 is formed in the cover front portion 211. Further, a second opening 211b for exposing the recovery switch 24 and the telephone jack 25 provided in the housing of the transmitter main body 20 is formed in the cover front portion 211. The first opening 211a is provided at a position overlapping the front portion 281 of the pushing portion 28 when viewed from the front of the transmitter 2. When a fire occurs, the user can press the push button 22 by pushing the pushing portion 28 through the first opening 211a.

[0042] The second opening 211b is provided at a position corresponding to the recovery switch 24 and the telephone jack 25 provided in the transmitter main body 20 when viewed from the front of the transmitter 2. The transmitter cover 21 is provided with a window 213 that covers the second opening 211b in an openable and closable manner. When a fire occurs, the user can open the window 213 and connect a handset (not shown) to the telephone jack 25 through the second opening 211b. Further, after operating the transmitter 2, the user can open the window 213 and press the recovery switch 24 through the second opening 211b to recover the transmitter 2 from the operating state.

[0043] The push button 22 has a light source unit 221 and a touch panel 222, and emits light. The touch panel 222 includes a liquid crystal unit that emits the light of the light source unit 221, and a detection sensor (not shown) that detects that the touch panel 222 has been pressed. The light source unit 221 may be configured with a backlight or the like, similar to the light source unit 121 of the first embodiment. Also, the liquid crystal unit of the touch panel 222 may be configured with a liquid crystal panel or the like, similar to the liquid crystal unit 122 of the first embodiment. The detection sensor of the touch panel 222 is configured with, for example, a sensor that detects a change in capacitance, or a sensor that senses a pressure equal to or greater than a certain level. For example, the detection sensor of the touch panel 222 is configured with a transparent conductive film made of ITO (Indium Tin Oxide) or the like, and is disposed in front of the liquid crystal unit. The detection sensor may be provided in a range that at least overlaps the shaft portion 282 of the push-in portion 28 when viewed from the front of the transmitter 2. A general touch panel 222 in which the detection sensor is laminated on the liquid crystal unit may be used, and the detection sensor may be configured to cover the entire front surface of the liquid crystal unit. The push button 22 is connected to the substrate 23, and the substrate 23 controls the light emission.

[0044] The light source unit 221 of the push button 22 is provided on the front surface of the substrate 23. Also, the touch panel 222 of the push button 22 is provided at a position corresponding to the push-in portion 28 of the substrate 23 so as to cover the light source unit 221 provided on the front surface of the substrate 23. The touch panel 222 may be provided in a range that at least overlaps the shaft portion 282 of the push-in portion 28 when viewed from the front. Also, the touch panel 222 is separated from the rear end portion of the shaft portion 282 when the push-in portion 28 is not pushed in.

[0045] The outer peripheral portion 26 of the main body of the housing further has a partition wall 263 and a first guide portion 264 that restrict the movement of the pushing portion 28 within the push button storage portion 262. The partition wall 263 partitions the storage space 262a formed within the push button storage portion 262 into a front side and a rear 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 a shaft hole 263a into which the shaft portion 282 of the pushing portion 28 is inserted is formed in the partition wall 263. Further, as shown in FIG. 9, a cylindrical second guide portion 263b extending rearward is formed at the edge of the shaft hole 263a on the back surface of the partition wall 263. When the pushing portion 28 is pushed rearward, the second guide portion 263b guides the shaft portion 282 to move along the second guide portion 263b. The first guide portion 264 is composed of, for example, a pair of plate-like members provided along the left and right inner surfaces 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 rearward, the first guide portion 264 guides the front surface 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 pushing portion 28 can be smoothly moved rearward within the housing.

[0046] The transmitter main body 20 also includes a cushioning material 29 that alleviates the impact applied to the touch panel 222 when the pushing portion 28 is pushed. The cushioning material 29 is composed of, for example, an elastic member. In an 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. The cushioning material 29 is arranged such that when the front surface portion 281 of the pushing portion 28 is pushed, the front end portion contacts the back surface of the front surface portion 281 of the pushing portion 28, and the rear end portion contacts the portion around the shaft hole 263a on the front surface of the partition wall 263.

[0047] By providing the cushioning material 29, when the pushing portion 28 is pushed, it is possible to avoid the force applied by a person from directly acting on the touch panel 222, and prevent damage to the liquid crystal portion and the detection sensor of the touch panel 222. Note that the configuration of the cushioning material 29 is not limited to this.

[0048] The substrate 23 has a drive circuit for driving the light source unit 221 and the liquid crystal part of the touch panel 222, together with a circuit that outputs a fire signal. A detection signal indicating that the push button 22 has been pressed is input to the substrate 23 from the detection sensor of the touch panel 222. Further, the substrate 23 outputs a fire signal when the detection signal is input. Further, when the detection signal is input, the substrate 23 controls the light source unit 221 and the touch panel 222 so that the push button 22 emits light.

[0049] Here, it is assumed that the push button 22 does not normally emit light, and a configuration in which the push button 22 is made to emit light when it is detected that the push button 22 has been pressed will be exemplified. With such a configuration, it is possible to notify the person who has pushed the push-in part 28 that the push button 22 located inside the push-in part 28 has been pushed.

[0050] Note that the timing for making the push button 22 emit light is not limited to such a configuration. For example, the push button 22 may be configured to always emit light and always display the presence of the push button 22 to the user. Alternatively, the push button 22 may be configured to change the light emission pattern when it is being pressed and when it is not being pressed.

[0051] Next, with reference to FIGS. 7 to 9, an example of the operation of the transmitter 2 when the push button 22 of the transmitter 2 is pressed during a fire will be described. When the pushing portion 28 is pushed through the first opening 211a provided in the front surface portion 211 of the cover of the transmitter 2, the pushing portion 28 moves backward along the first guide portion 264 and the second guide portion 263b, and the touch panel 222 is pushed by the rear end portion of the shaft portion 282. At this time, the impact applied to the touch panel 222 is mitigated by the buffer material 29. When the touch panel 222 is pushed by the shaft portion 282, a force equal to or greater than a certain level is applied to the detection sensor of the touch panel 222, and the detection sensor detects that the push button 22 has been pressed, and a detection signal is output to the substrate 23. When the detection signal is input from the detection sensor to the substrate 23, the substrate 23 determines that the push button 22 has been pressed, outputs a fire signal, and outputs a drive signal to the light source portion 221 and the touch panel 222. The fire signal output from the substrate 23 is transmitted from the transmitter 2 to a receiver (not shown) or the like, and the fire is reported. The light source portion 221 and the touch panel 222 are driven by the drive signal from the substrate 23, and the push button 22 disposed 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 pushing portion 28 by the shaft portion 282 inserted into the shaft hole 263a of the partition wall 263 in the pushing 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.

[0052] As described above, in the second embodiment, since the transmitter 2 includes the push button 22 including the liquid crystal portion, the directivity of the light of the push button 22 can be arbitrarily changed, and visibility can be ensured regardless of the installation location or the like.

[0053] In addition, the transmitter 2 includes a pushing portion 28 and a buffer member 29 that mitigates the impact applied to the touch panel 222 when the pushing portion 28 is pushed. Thereby, even when the light directivity 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 pushed can be mitigated, and damage to the push button 22 having the light source unit 221 and the touch panel 222 can be avoided.

[0054] Note that 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. However, at least one of the above display lamp 1 and the transmitter 2 may be applied to an integrated display lamp transmitter 3 (see FIGS. 1 to 4) in which the transmitter and the display lamp are integrally configured. Further, at least one of the above display lamp 1 and the transmitter 2 may be applied to a device such as an emergency warning device.

[0055] Also, in the display lamp integrated transmitter 3, the liquid crystal part 122 of the display lamp 1 and the liquid crystal part of the touch panel 222 of the transmitter 2 may be formed continuously. For example, when the display lamp integrated transmitter 3 has a circular shape when viewed from the front and the liquid crystal part 122 of the display lamp 1 has an annular shape (see FIGS. 1 to 3), the shape of the liquid crystal part 122 is made into a disk shape instead of an annular shape, and the light emitting part storage part 134 and the push button storage part 262 are made into a continuous space. A detection sensor for the push button 22 is provided in a portion of the continuously formed liquid crystal part 122 that faces the first opening 211a of the transmitter 2. In this case, a light shielding plate may be provided in a region of the continuously formed liquid crystal part 122 where light emission is not intended, for example, a region excluding the region overlapping the push button 22 from the region overlapping the transmitter 2 when viewed from the front. Alternatively, instead of providing the light shielding plate, the control unit 14 may make the region non-luminous. According to such a configuration, the shapes of the liquid crystal parts 122 of the display lamp 1 and the transmitter 2 can be simplified, and molding becomes easy. Also, in the display lamp integrated transmitter 3, the pushing part 28, the partition wall 263, the first guide part 264, etc. may be omitted, and in the depth direction, the positions of the light source part 221 and the liquid crystal part of the transmitter 2 may be configured to coincide with the positions of the light source part 121 and the liquid crystal part 122 of the display lamp 1. In this case, a configuration can be adopted in which a person directly presses the detection sensor of the push button 22, the number of parts can be reduced, and the depth dimension of the display lamp integrated transmitter 3 can be reduced. Also, the display lamp integrated transmitter 3 of Embodiment 1 was configured to house the transmitter 2 in a separate housing from the display lamp housing 13 inside the display lamp housing 13 of the display lamp 1. However, the housing of the display lamp 1 and the housing of the disaster prevention device such as the transmitter 2 may be integrally configured. Also, in Embodiment 2, the case where the detection sensor is arranged in front of the liquid crystal part in the touch panel 222 was described, but it may be arranged behind the liquid crystal part, and it may be arranged appropriately according to the detection method of the detection sensor and the like.
