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

  Next, the light guide 2 is positioned with respect to the component board 5. Although the specific method is arbitrary, for example, the indicator lamp board 41 is arranged so that the projection of the component board side positioning portion 54 of the component board 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 overlapped from the front side (+ Z direction) with respect to the stacked component plates 5 and positioned. In this case, the light guide 2 faces the substrate facing portion 51 through the display lamp substrate 41 and directly faces the substrate non-facing portion 52 without going through the display lamp substrate 41.

  Next, the light guide 2 and the indicator lamp substrate 41 are fixed to the component board 5. Although the specific method is arbitrary, 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 and the component plate side light guide screwing portion 53 of the component plate 5 is inserted. Screw in the screw hole and fix. In this case, the light guide 2 is fixed and attached to the component board 5 by screwing of the light guide fixing screw S12.

  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 S <b> 11.

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

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

  First, the front light-emitting part 81 of FIG.8 and FIG.9 light-emits toward the front side (+ Z direction) of the transmitter 100 with an indicator lamp. In this case, the light from the front light emitting unit 81 is applied to the diffusing unit 71, the direction is changed by the diffusing unit 71, and the light guide 2 is rotated along the clockwise and counterclockwise directions of the light guide 2. 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 of the transmitter with indicator light 100. In this case, light from the side light emitting portion 82 enters the light guide 2 via the incident portion 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.

  Thereafter, the light guided by the light guide 2 is output to the outside of the transmitter with indicator lamp 100 on the front side of the transmitter with indicator lamp 100 through the transmission region 13 of the front cover 1. In this case, in particular, as described above, the transmission region 13 of FIG. 3 is provided not only on the front surface portion 11 of the front cover 1 but also on the side surface portion 12, so that 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 with indicator light 100 emits light in red from any position on the front side of the transmitter with indicator light 100. .

(Report operation)
Next, a notification operation, which is an operation in which the transmitter with indicator light 100 notifies the occurrence of a fire, will be described. Here, for example, the notification operation when the user presses the protective plate 42 via the exposure opening 17 will be described. However, since this notification operation is the same as the conventional one, only the 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 electrical circuit of the transmitter board 61 is disaster-reduced via a communication line (not shown). Send a fire report signal, a signal to report a fire to the receiver. In this way, the reporting operation is performed.

(Direction) is required to meet the required standards (for example, standards related to the Fire Service Act), and with a light indicator at multiple locations, with an indicator light compared to light emission at only one location The transmitter 100 can be made conspicuous.

  In addition, since the area facing the light emitting part 3 in the front cover 1 of FIG. 2 is the upper non-transmissive area 142 and the lower non-transmissive area 143, the area facing the light emitting part 3 is shielded to emit light. Since the light intensity of the portion 3 is increased and the region where the light emission state tends to be mottled can be shielded, the entire transmission region 13 of the front cover 1 can be made to emit light uniformly, including the light-transmitting transmission region 13. The overall designability of the transmitter with indicator lamp 100 can be improved. In particular, since the area facing the upper non-transmission area 142 and the lower non-transmission area 143 in the transmitter with indicator lamp 100 can be used as the area where the light emitting section 3 is provided, the area where the light emitting section 3 is provided is 2 The transmitter 100 with indicator lamp can be made compact by making effective use of the space inside the transmitter 100 with indicator lamp.

(Effect of embodiment)
As described above, according to the present embodiment, the front cover 1 includes a plurality of transmission regions 13 and the light guide 2 is provided over the plurality of transmission regions 13. The display performance can be improved by emitting light, and the number of the light guides 2 can be made smaller than the number of the transmissive regions 13, so that the number of parts can be reduced and the manufacturing cost can be reduced.

  Moreover, by providing the diffusion unit 71 that diffuses the light emitted from the front light emitting unit 81 toward the side surface into the light guide 2, for example, the light can be uniformly guided in the entire light guide 2. Therefore, the transmitter with indicator lamp 100 can be made conspicuous in all directions, and the display performance can be improved.

  Further, since the light guide 2 includes the upper light emitting unit 31, for example, at least the side light emitting unit 82 can be accommodated in the upper light emitting unit 31. It is not necessary to increase the thickness of the transmitter, and the transmitter with indicator lamp 100 can be made compact. In addition, by including the incident unit 72 that allows the light emitted from the side light emitting unit 82 to enter, for example, the light from the side light emitting unit 82 can be reliably incident on the light guide 2. Since relatively strong light can be guided, the transmitter with indicator lamp 100 can be made conspicuous in all directions, and display properties can be improved.

  In addition, the incident portion 72 is a position shifted from each other in the radial direction of the light guide 2 so as to face the plurality of side light emitting portions 82, and a plurality of positions are shifted from each other in the circumferential direction of the light guide 2. By being provided, for example, the plurality of side light emitting units 82 can be provided so as to be shifted from each other, so that an element (for example, a so-called land that functions as a terminal) for mounting the plurality of side light emitting units 82 is provided. It is possible to prevent interference and mount the plurality of side light emitting units 82 in a dense manner, and the transmitter 100 with indicator lamp can be made compact.

  In addition, a first outer peripheral incident portion 721 and a first inner peripheral incident portion 722 that receive light emitted by the first outer peripheral side light emitting portion 821 and the first inner peripheral side light emitting portion 822 that emit light along the counterclockwise direction, By including a second outer peripheral incident portion 723 and a second inner peripheral incident portion 724 that allow the light emitted by the second outer peripheral side light emitting portion 823 and the second inner peripheral side light emitting portion 824 to emit light along the clockwise direction. For example, since the light guide 2 can guide light from both the counterclockwise direction and the clockwise direction, the light guide 2 is guided uniformly throughout the light guide 2 and has a relatively strong intensity. Therefore, the indicator light-equipped transmitter 100 can be made conspicuous in all directions, and the display property can be improved.

Further, since the light guide side mounting portion 24 is provided inside the light guide 2, for example, the outer shape of the transmitter with indicator lamp 100 can be determined without being limited by the shape of the light guide side mounting portion 24. Therefore, the freedom degree of design of the transmitter 100 with an indicator light can be improved. In addition, for example, since light can be guided in the entire outer peripheral portion of the light guide 2, light can be emitted in all directions of the transmitter with indicator light 100. It can be made conspicuous and display properties can be improved.

In addition, by providing an incident surface on which the light emitted from the side light emitting means is incident, for example, light from the side light emitting means can be reliably incident on the light guiding means. Since the light with high intensity can be guided, the transmitter with an indicator lamp can be made conspicuous in all directions, and the display property can be improved.

  According to the transmitter with an indicator lamp described in the supplementary note 4, the incident surface is a position shifted from each other in the radial direction of the light guide unit so as to face the plurality of side surface side light emitting units, and the light guide unit Since the plurality of side surface light emitting means can be provided to be shifted from each other, for example, an element for mounting the plurality of side surface side light emitting means ( For example, a so-called land functioning as a terminal can be prevented from interfering with each other, and a plurality of side-side light emitting means can be densely mounted, and the transmitter with indicator lamp can be made compact.

  According to the transmitter with an indicator lamp described in Appendix 5, the first incident surface on which the light emitted by the first side-side light emitting means that emits light along the first circumferential direction is incident, and the second circumferential direction And a second incident surface on which the light emitted by the second side surface light emitting means that emits light is incident, for example, guides light from both the first circumferential direction and the second circumferential direction. Since the light means can guide light, light can be uniformly guided in the entire light guide means, and light of relatively strong intensity can be guided, so that display is possible in all directions. A transmitter with a light can be made conspicuous and display properties can be improved.

  According to the transmitter with an indicator light described in appendix 6, the outer shape of the transmitter with an indicator light is determined without being limited by the shape of the attachment means, for example, because the attachment means is provided inside the light guide means. Therefore, the degree of freedom in designing the transmitter with indicator light can be improved. Further, for example, since light can be guided in the entire outer peripheral portion of the light guide means, light can be emitted in all directions of the transmitter with indicator light, so that the transmitter with indicator light is made conspicuous in all directions. Display properties can be improved.
