For example, it is a protrusion that is continuously inserted into the light guide side positioning unit 23 and the substrate side positioning unit 412, and is provided at two places in total.

(Assembly and installation method)
Next, a method of assembling and installing the transmitter 100 with an indicator light will be described.

First, the indicator lamp board 41 is positioned with respect to the component plate 5. The specific method is arbitrary, but for example, the protrusion of the component plate side positioning portion 54 of the component plate 5 is inserted into the positioning hole of the substrate side positioning portion 412 of the indicator lamp board 41 with respect to the component plate 5. The indicator lamp board 41 is overlapped and positioned from the front side (+ Z direction). In this case, the indicator light board 41 faces the board facing portion 51.

Next, the light guide 2 is positioned with respect to the component plate 5. The specific method is arbitrary, but for example, the indicator lamp board 41 is inserted so that the protrusion of the component plate side positioning portion 54 of the component plate 5 is inserted into the positioning hole of the light guide side positioning portion 23 of the light guide 2. The light guide 2 is placed on the stacked component plates 5 from the front side (+ Z direction) for positioning. In this case, the light guide 2 faces the substrate facing portion 51 via the indicator lamp substrate 41, and directly faces the substrate non-opposing portion 52 without passing through the indicator lamp substrate 41.

Next, the light guide 2 and the indicator light board 41 are fixed to the component plate 5. The specific method is arbitrary, but for example, the light guide fixing screw S12 is passed through the through hole of the light guide side mounting portion 24 of the light guide 2 to the component plate side light guide screwing portion 53 of the component plate 5. Screw it into the screw hole to fix it. In this case, the light guide 2 is fixed and attached to the component plate 5 by screwing the light guide fixing screw S12. Further, in this case, the light guide 2 is fixedly attached to the component plate 5 by being sandwiched between the component plate 5 and the light guide 2.

Next, the protective plate 42 of FIG. 5, the holding spring 43, the switch 44, the transmitter board 61 of FIG. 4, and the board cover 62 are screwed to the component plate 5 by any fixing means (for example, with screws). , Engagement in an engagement structure, or engagement in a fitting structure, etc.).

Next, after inserting a part of the component plate 5 into the opening of the sheet metal 91 in FIG. 4, the component plate 5 is screwed and attached to the sheet metal 91 using the component plate fixing screw S11.

Next, the front cover 1 is attached to the component plate 5 by any fixing means (for example, screwing with a screw, engagement with an engagement structure, etc.). This completes the assembly and installation of the transmitter 100 with an indicator light.

(Light emission)
Next, the light emission by the transmitter 100 with an indicator light will be described. Here, for example, the optical path of light when the light emitting unit 3 emits light to the light guide 2 will be described, but the optical path of light from the upper light emitting unit 31 and the optical path of light from the lower light emitting unit 32 are mutually exclusive. Since the same applies to the above, only the optical path of the light from the upper light emitting unit 31 will be described.

First, the front light emitting unit 81 of FIGS. 8 and 9 emits light toward the front side (+ Z direction) of the transmitter 100 with an indicator light. In this case, the light from the front light emitting unit 81 is applied to the diffusing unit 71, and the direction is changed by the diffusing unit 71 so that the light guide 2 is along the clockwise and counterclockwise directions of the light guide 2. It will be spread throughout. That is, in this case, the light guide 2 guides the light from the front light emitting unit 81.

Further, the side light emitting unit 82 emits light toward the side surface side of the transmitter 100 with an indicator light. In this case, the light from the side light emitting unit 82 enters the light guide 2 via the incident unit 72 and is guided to the entire light guide. That is, in this case, the light guide 2 guides the light from the side light emitting unit 82.

After that, the light guided by the light guide 2 is output to the outside of the transmitter 100 with an indicator lamp on the front side of the transmitter 100 with an indicator lamp via the transmission region 13 of the front cover 1. In this case, in particular, since the transmission region 13 of FIG. 3 is provided on the side surface portion 12 in addition to the front surface portion 11 of the front cover 1 as described above, light is emitted from the side surface portion 12 in addition to the front surface portion 11. Therefore, the user can visually confirm that a part of the transmitter 100 with an indicator light emits light in red from any position on the front side of the transmitter 100 with an indicator light. ..

(Report operation)
Next, a notification operation, which is an operation in which the transmitter 100 with an indicator light reports the occurrence of a fire, will be described. Here, for example, a notification operation when the user presses the protective plate 42 through the exposed opening 17 will be described, but since this notification operation is the same as in the conventional case, only an outline will be described.

When the user presses the protective plate 42 through the exposed opening 17, the switch 44 is pressed together with the protective plate 42, and the electric circuit of the transmitter board 61 is disaster-prevented via a communication line (not shown). A fire notification signal, which is a signal to notify the receiver of a fire, is transmitted to notify the receiver. In this way, the notification operation is performed.

(Effect of the shape of the transparent area)
As described above, since the transmission region 13 of FIG. 2 includes two arcuate left-side transmission regions 131 and right-side transmission regions 132 in the lateral direction (X direction), the transmitter 100 with an indicator light has a lateral direction (X). After ensuring that certain standards (for example, standards related to the Fire Service Act) that require visibility from the direction) are met, the light emitted from multiple locations is accompanied by an indicator light compared to the emission from only one location. The transmitter 100 can be made to stand out.

Further, since the regions of the front cover 1 of FIG. 2 facing the light emitting portion 3 are the upper non-transmissive region 142 and the lower non-transmissive region 143, light emission is performed by shading the region facing the light emitting portion 3. Since the region where the amount of light of the unit 3 is strong and the light emitting state is likely to be mottled can be shielded, the entire transmission region 13 of the front cover 1 can be uniformly emitted, and the transmission region 13 which is emitting light is included. It is possible to improve the overall design of the transmitter 100 with an indicator light. In particular, since the region facing the upper non-transmissive region 142 and the lower non-transmissive region 143 inside the transmitter 100 with an indicator light can be used as the region where the light emitting unit 3 is provided, the region where the light emitting unit 3 is provided is 2 It is possible to concentrate on the location, and by effectively utilizing the space inside the transmitter 100 with an indicator light, it is possible to make the transmitter 100 with an indicator light more compact.

(Effect of embodiment)
As described above, according to the present embodiment, the front light emitting unit 81 that emits light to the light guide 2 toward the front side (+ Z direction) and the side light emitting unit that emits light to the light guide 2 toward the side surface side. By providing the 82, for example, since light from a plurality of directions is incident on the light guide 2, the light can be guided by the entire light guide 2, so that the transmission region 13 of the front cover 1 is provided. Light can be uniformly output from the whole, and the transmitter 100 with an indicator light can be made to stand out in all directions, and the displayability can be improved. Further, for example, since two types of the front light emitting unit 81 and the side light emitting unit 82 can be mounted, various mounting patterns can be adopted as compared with the case where one type is mounted, so that the transmitter with an indicator light can be used. The degree of freedom in designing 100 can be improved.

Further, the plurality of side light emitting portions 82 are provided at positions displaced from each other in the radial direction of the light guide 2 and at positions displaced from each other in the circumferential direction of the light guide 2, for example. Since the side light emitting portions 82 of the above can be provided so as to be staggered from each other, it is possible to prevent elements for mounting the plurality of side light emitting portions 82 (for example, so-called lands functioning as terminals) from interfering with each other, and a plurality of side light emitting portions 82 are provided. The side light emitting portions 82 can be compactly mounted, and the transmitter 100 with an indicator lamp can be made compact.

Further, the first outer peripheral side light emitting unit 821 and the first inner peripheral side light emitting unit 822 that emit light in the counterclockwise direction, and the second outer peripheral side surface light emitting unit 823 and the second inner peripheral side surface that emit light in the clockwise direction. By providing the light emitting unit 824, for example, the light guide 2 can guide the light from both the counterclockwise direction and the clockwise direction, so that the light is uniformly guided by the entire light guide 2. Moreover, since the light having a relatively strong intensity can be guided, the transmitter 100 with an indicator lamp can be made to stand out in all directions, and the displayability can be improved.

Further, the indicator light board 41 connects a plurality of positions where the combination of the front light emitting unit 81 and the side light emitting unit 82 is provided at the shortest distance while avoiding the switch 44, whereby, for example, the area of the indicator light board 41. Since it is possible to prevent the transmitter 100 from becoming larger than necessary, the transmitter 100 with an indicator light can be made compact.

Further, since the indicator lamp substrate 41 includes the reflection layer 411, for example, the amount of attenuation of the light guided by the light guide 2 can be suppressed, so that light of relatively strong intensity can be guided. Therefore, the transmitter 100 with an indicator light can be made to stand out in all directions, and the displayability can be improved.

Further, the substrate of the component plate 5 which is a portion where the substrate facing portion 51 of the component plate 5 which is a portion facing the light guide 2 via the indicator lamp substrate 41 faces the light guide 2 without passing through the indicator lamp substrate 41. By being recessed with respect to the non-opposing portion 52, for example, the thickness of the indicator lamp substrate 41 can be absorbed by the component plate 5, so that the transmitter 100 with an indicator lamp can be made thinner. Further, for example, it is possible to prevent the component plate 5 and the light guide 2 from rattling with each other due to the provision of the indicator lamp substrate 41.

Further, by providing the board-side positioning unit 412 and the component plate-side positioning unit 54, for example, the indicator light board 41 can be accurately positioned on the transmitter 100 with an indicator light, so that the positioning error of the indicator light board 41 can be reduced. As a result, it is possible to prevent the positions of the front light emitting unit 81 and the side light emitting unit 82 mounted on the indicator lamp board 41 from shifting, and light the light from the front light emitting unit 81 and the side light emitting unit 82. Since the guide 2 can reliably guide the light, the transmitter 100 with an indicator light can be made to stand out in all directions, and the displayability can be improved.
