(Modification 3)
FIG. 8 is a front view showing a modification of the transmitter with indicating light. As shown in FIG. 8, the transmitter 85 with indicator light includes the transmitter 12 and indicator lights 90 arranged to surround the transmitter 12 when viewed from the front.

The indicator lamp 90 includes a left indicator lamp 90A arranged on the left side of the transmitter 12 in a front view, and a right indicator lamp 90B arranged on the right side. Further, the indicator lamp 90 includes an upper indicator lamp 90C arranged above the transmitter 12 and a lower indicator lamp 90D arranged below the transmitter 12 when viewed from the front.

The indicator lamp 90 includes a left indicator lamp 90A, a right indicator lamp 90B, an upper indicator lamp 90C, and a lower indicator lamp 90D, which surround the transmitter 12 and are formed in a substantially square frame shape.

The indicator lamp 90 includes a surface member 91 having a substantially rectangular frame shape when viewed from the front. The surface member 91 is formed in a plate shape that is substantially flush with the mounting surface 15 . The surface member 91 is made of, for example, a light transmissive red resin plate. On the back side (internal space) of the surface member 91, there is provided a storage section in which the light emitting section is arranged. The storage part is formed in a rectangular parallelepiped shape corresponding to each part (side) of the rectangular shape.

The storage portions and light sources (mirror sheets) of the left indicator lamp 90A and the right indicator lamp 90B have substantially the same configuration as the left indicator lamp 70A and the right indicator lamp 70B.

A light source is arranged in the housing of the upper indicator lamp 90C and the lower indicator lamp 90D. The light sources are arranged, for example, so as to direct the front.

The optical path (81) irradiated from the second light source (corresponding to 77b) of the left indicator lamp 90A and the optical path (82) irradiated from the fourth light source (corresponding to 78b) of the right indicator lamp 90B intersect (83 ). The distance between the mounting surface 15 and the intersection (83) is set within 1 m. Here, since the light sources of the upper indicator lamp 90C and the lower indicator lamp 90D are arranged so as to face the front, even in the blind area (A1) where the light of the second light source and the fourth light source is difficult to reach, , the light sources of the upper indicator lamp 90C and the lower indicator lamp 90D can be reliably viewed.

By configuring in this manner, the indicator lamp 90 can realize a rectangular frame-like appearance when viewed from the front (the shape of the surface member 91), and when viewed from the side, it is substantially flush with the mounting surface. It is possible to achieve the appearance of

In addition, by providing the indicator lamp 90 so as to surround the transmitter 12 with the transmitter 12 as the center, the design can be improved and the indicator lamp 90 can be easily seen from either the left or right direction.

As described above, the embodiment of the present invention has been described in detail with reference to the drawings, but the specific configuration is not limited to this embodiment, and design changes and the like are included within the scope of the present invention.
Also, the constituent elements shown in the above-described embodiment and modifications can be combined as appropriate.

For example, in the above-described embodiments, the case of using an LED as a light source has been described, but the type of light source may be other than an LED.

In the above-described embodiment, the left light source 28 and the right light source 29 are used as the light sources, and the light reflected by the reflecting mirror is configured to form an optical path directed toward the front. It is possible to adopt an appropriate form as long as it is configured to be able to irradiate outward in the left-right direction at a given angle. For example, as shown in FIG. 9, a plurality of light sources 27 are arranged at predetermined intervals along the inner surface 25a of a semicylindrical housing 25, and the light from the light sources 27 is emitted from the center of the circle of the housing 25. You may take the form arrange|positioned so that it may direct.

In addition, in the above-described embodiment, the configuration in which the left light source 28 is provided with the first light source 28a and the second light source 28b is adopted, but as shown in FIG. An angle adjusting mechanism (angle adjusting mechanism 101) may be provided. The angle adjustment mechanism 101 includes, for example, a fixed column 102, a cylindrical angle adjustment portion 103 attached to the fixed column 102 and hollowed out at the center, and a columnar shape attached to the angle adjustment portion 103 and extending in the height direction. and a first light source 28a. Similarly, it is provided with a cylindrical angle adjusting portion 104 attached to the fixed column 102 and hollowed out at the center, and a columnar second light source 28b attached to the angle adjusting portion 104 and extending in the height direction. ing. The angle adjusters 103 and 104 are provided at different heights. With this configuration, the first light source 28a and the second light source 28b can be independently rotated around the fixed cylinder 102, and the direction of the light emitted from the left light source 28 can be easily adjusted. be able to. In other words, by providing the angle adjustment mechanism 101, it is possible to set the irradiation range in a wider range according to the structure of the place where it is actually placed, and to adjust (secure) the necessary irradiation range regardless of the accuracy of wall processing. ). Also, the right light source 29 may have a similar configuration.

Further, in the above embodiment, two light sources, the first light source 28a and the second light source 28b, are used to irradiate from one light source. Complementary light paths may be provided. For example, a plurality of light sources may be further arranged between the first light source 28a and the second light source 28b, or a light diffusing member such as smoke may be used. Further, instead of arranging the first light source 28a and the second light source 28b, a light source that emits diffused light may be arranged in the optical path to be performed by the first light source 28a and the second light source 28b. For example, a light source may be arranged at an arbitrary position between the positions where the first light source 28a and the second light source 28b should be arranged, and a light diffusing member may be provided as necessary. Of course, the third light source and the fourth light source may be treated similarly.

Further, in Modification 3, the indicator lamps 90 are formed in a substantially square frame shape surrounding the transmitter 12. However, the indicator lamps 90 are provided on both sides of the transmitter 12 in the left-right direction and on both sides in the up-down direction so that the transmitter 12 can be seen from the front. Another form may be taken as long as it is an enclosing form. For example, as shown in FIG. 11, the indicator light 110 has the central portion 111 removed from the display portions provided on both sides in the vertical direction, and U-shaped display portions 110a and 110b are provided in the horizontal direction of the transmitter 12. may If the U-shaped display portions 110a and 110b are provided in the horizontal direction of the transmitter 12, the inside and outside of the frame of the indicator light 110 are not completely separated, so the indicator light 110 and the transmitter 12 are attached independently. In addition, in terms of design, it is possible to produce an effect of emphasizing the transmitter 12 as in the case where the indicator lamp has a substantially rectangular frame shape.

Further, in the second and third modifications, the light path is based on the reflecting mirror, but a light path that does not pass through the reflecting mirror may be formed. Specifically, the light source is arranged on the front side of the first light source to irradiate the transmitter side with light. Furthermore, as shown in FIG. 12, by forming the peripheral edge portion 120a of the transmitter 120 on a convex curved surface, the light reflected by the peripheral edge portion 120a of the transmitter 120 is directed in the front direction, can be emphasized. Furthermore, by coating the peripheral portion 120a of the transmitter 120 with the luminous material 121 or by adopting a material that is easily reflective, it is possible to exhibit a further effect.

Further, regarding the transmitter that causes the pressing operation part to light up and display when the pressing operation is performed, the pressing operation part lights up in the first mode when the pressing operation is not performed, and the pressing operation part lights up in the second mode different from the first mode when the pressing operation is performed. You may make it display.
Specifically, there is already known a transmitter that turns on a confirmation light provided inside the pressing operation portion when the pressing operation is performed, but the confirmation lamp can also take a plurality of light emitting forms, such as a two-color LED. Configure with possible indicator lights. As a result, for example, by performing lighting display in the first form during normal times, it is possible to clearly display the actual operating position of a transmitter installed in a dark place in addition to the approximate position indicated by the indicator light. , and the effect of helping the operation can be obtained.
Further, the lighting display may be performed in a second mode different from the first mode by a signal from the fire alarm system. This enables lighting at night and lighting during testing.

Further, in the above-described embodiments, there is a configuration in which a mirror sheet is used to reflect the light from the light source, but the method for outwardly irradiating the light from the light source is not limited to the above method.
