SUMMARY OF THE INVENTION
Technical Problem

However, this display light device is configured to be separate from the transmitter and provided next to the transmitter so as to protrude to a relatively large extent from an installation surface so that the position of the transmitter is displayed in every direction. As a result, the display light device may act as, for example, a hindrance in the building.

Although a retrofit display light device that can be retrofitted into the transmitter according to the related art has been proposed, conceivable are the following first and second problems.

Proposed with regard to the first problem is the retrofit display light device according to the related art being configured to be flat as a whole, being configured to be retrofittable into the transmitter according to the related art by means of a screw or the like, and being configured such that a display light is provided along the periphery of the transmitter in the case of retrofitting into the transmitter.

However, this retrofit display light device may become dirty as a contaminant such as rain and dust enters the device from the gap between the transmitter (that is, a part emitting no light) and the retrofit display light device (light emitting part) in a case where, for example, the retrofit display light device is retrofitted into the transmitter. Besides, as for this retrofit display light device, the transmitter and the retrofit display light device as a whole may, for example, lack a sense of unity and give an impression of complexity as the retrofit display light device is retrofitted into the transmitter.

Accordingly, there is room for improvement in terms of contaminant infiltration prevention and overall design improvement.

Proposed with regard to the second problem is the retrofit display light device according to the related art being configured to be flat as a whole and being configured to be retrofittable into the transmitter according to the related art by means of a screw or the like. Specifically, according to the proposal, the retrofit display light device is configured to surround the periphery of the transmitter with the transmitter exposed toward a front surface side, a display light is provided at this surrounding part (hereinafter, referred to as the surrounding part), and the retrofit display light device is configured such that the display light is provided along the periphery of the transmitter in the case of retrofitting into the transmitter.

However, this retrofit display light device is configured such that, for example, the light of the display light is emitted only toward the front surface side with the display light embedded at the surrounding part so that the overall shape of the retrofit display light device is flat. As a result, it may be difficult to visually recognize the light of the display light from the side surface side of the transmitter in a case where the retrofit display light device is retrofitted into the transmitter.

Accordingly, there is room for improvement in terms of transmitter position recognition by a user.

It is an object of the present invention to solve the problems of the above mentioned prior arts.

Solution to Problem

One aspect of the present invention provides a display light-equipped transmitter providing notification of an abnormality in a monitoring region, the display light-equipped transmitter comprises: a light emitting unit; and a front cover.

For example, “address information” is information on an address used for communication with the disaster prevention receiver and set in the display light-equipped transmitter 100. “Disaster prevention receiver” is an external device monitoring and reporting a fire in the monitoring region. For example, “disaster prevention receiver” is a device electrically connected to at least the display light-equipped transmitter 100. In addition, “operation guide information” is operation guiding information for the display light-equipped transmitter 100. For example, “operation guide information” is procedure guiding information on the operation of the pressing spring 43 for returning the protective plate 42 in a pressed state to the original position of the protective plate 42.

All of the information can be displayed in the first component plate side name plate portion 53 by any method. For example, the model number, the firefighting certification number, and the rating of the light emitting unit 3, which are text information for inspection, are displayed along with the operation guide information at a position facing the opening and closing opening portion 15 in the thickness direction (Z direction) and the system information and the address information are displayed along with the date of manufacture and the serial number, which are text information for inspection, at a position facing the opening and closing opening portion 15 in the thickness direction (Z direction) with the importance of each information piece and the like taken into account.

(Configuration-Details-Component Plate-Second Component Plate Side Name Plate Portion)

The second component plate side name plate portion 54 is an inspection information display unit that displays at least the second inspection information out of the inspection information on the display light-equipped transmitter 100. For example, the second component plate side name plate portion 54 displays only the second inspection information. In addition, for example, the second component plate side name plate portion 54 is similar in configuration to the first component plate side name plate portion 53 except for the position and the shape of the second component plate side name plate portion 54.

(Assembly and Installation Methods)

Next, methods for assembling and installing the display light-equipped transmitter 100 will be described.

First, the light guide 2, the display light board 41, the protective plate 42, the pressing spring 43, and the switch 44 in FIG. 5 and the transmitter board 61 and the board cover 62 in FIG. 4 are attached to the component plate 5 by any fixing unit (such as screwing with a screw, engagement with an engagement structure, and fitting with a fitting structure).

Next, a part of the component plate 5 is inserted into the opening portion of the sheet metal 91 illustrated in FIG. 4. Subsequently, the component plate 5 is screwed and attached to the sheet metal 91 by means of a component plate fixing screw S12.

Next, the front cover 1 is engaged with the component plate 5. Specifically, the front cover 1 is engaged with the component plate 5 by, for example, mutual engagement between the front cover side engagement portion 18 of the front cover 1 and the component plate side front cover engagement portion 51 of the component plate 5. In this case, the mutual rotation of the front cover 1 and the component plate 5 is locked by the front cover side engagement portion 18 and the component plate side front cover engagement portion 51 and the front cover 1 is temporarily fixed to the component plate 5.

Next, the front cover 1 is fixed to the component plate 5. Specifically, for example, the front cover fixing screw S11 is screwed through the through hole of the front cover side fixing portion 19 of the front cover 1 via the opening and closing opening portion 15 and fixed by screwing into the screw hole of the component plate side front cover screwing portion 52 of the component plate 5 in a state where the display plate 16 of the front cover 1 is open. In this case, the outer peripheral side of the front cover 1 is engaged and the center side of the front cover 1 is screwed, and thus the front cover 1 is reliably fixed to the component plate 5. Especially, the fixing can be performed with the single front cover fixing screw S11, and thus screwing at a plurality of points is not necessary and the front cover 1 can be easily fixed to the component plate 5. The assembly and installation of the display light-equipped transmitter 100 are completed as a result.

(Light Emission)

Next, the light emission by the display light-equipped transmitter 100 will be described. Described here is, for example, the optical path of light in a case where the light emitting unit 3 has emitted light to the light guide 2.

First, the light emitted by the light emitting unit 3 is incident on the light guide 2 and guided to the entire light guide 2. Subsequently, the light guided by the light guide 2 is output to the outside of the display light-equipped transmitter 100 that is on the front side of the display light-equipped transmitter 100 via the transmitting region 13 of the front cover 1. In this case in particular, light emission is possible from the side surface portion 12 as well as the front surface portion 11 since the transmitting region 13 in FIG. 3 is provided in the side surface portion 12 as well as the front surface portion 11 of the front cover 1 as described above, and thus a user can visually recognize and confirm from every position on the front side of the display light-equipped transmitter 100 that a part of the display light-equipped transmitter 100 emits light in red.

(Notification Operation)

A notification operation will be described below. The display light-equipped transmitter 100 provides notification of the outbreak of a fire by means of the notification operation. Described here is, for example, a notification operation in a case where a user has pressed the protective plate 42 via the exposing opening portion 17. This notification operation is similar to the notification operation in the related art, and thus only the outline of the notification operation will be described below.

In a case where a user presses the protective plate 42 via the exposing opening portion 17, the switch 44 is pressed together with the protective plate 42. As a result, the electric circuit of the transmitter board 61 provides notification by transmitting a fire notification signal, which is a signal for fire notification, to the disaster prevention receiver via a communication line (not illustrated). The notification operation is performed in this manner.

(Effect of Shape of Transmitting Region)

As described above, the transmitting region 13 illustrated in FIG. 2 is provided with the two-circular arc-shaped left transmitting region 131 and right transmitting region 132 in the lateral direction (X direction). As a result, the display light-equipped transmitter 100 can be more conspicuous than in the case of single-point light emission by means of light emission at a plurality of points and it is possible to reliably meet predetermined standards requiring the lateral (X-direction) visibility of the display light-equipped transmitter 100 (such as standards related to the Fire Services Act).

In addition, the upper non-transmitting region 142 and the lower non-transmitting region 143 face the light emitting unit 3 in the front cover 1 illustrated in FIG. 2. Accordingly, light blocking can be performed in the regions where mottles in terms of the state of light emission are likely to result from an increase in the light quantity of the light emitting unit 3 by means of light blocking in the regions facing the light emitting unit 3, and thus it is possible to cause the entire transmitting region 13 of the front cover 1 to emit light with uniformity and improve the design of the entire display light-equipped transmitter 100 including the transmitting region 13 emitting light. Especially, the region that faces the upper non-transmitting region 142 and the lower non-transmitting region 143 in the display light-equipped transmitter 100 can be used for the light emitting unit 3 to be provided, and thus the region where the light emitting unit 3 is provided can be concentrated in two places. As a result, the display light-equipped transmitter 100 can be compact by means of an effective use of the internal space of the display light-equipped transmitter 100.

Effect of Embodiment 1

In the present embodiment, the transmitting region 13 and the non-transmitting region 14 of the front cover 1 are configured integrally with each other as described above. Accordingly, no gap or the like is provided between the transmitting region 13 and the non-transmitting region 14, and thus it is possible to prevent a contaminant such as rain and dust from entering the display light-equipped transmitter 100. In addition, for example, it is possible to give an impression of unity and integrity with regard to the entire front cover 1, and thus the design of the display light-equipped transmitter 100 can be improved.

In addition, in the transmitting region 13, the transmitting layer L12 is provided with the non-transmitting layer L11 and the transmitting layer L12 not overlapping with each other. The non-transmitting region 14 is a region including a region where the non-transmitting layer L11 and the transmitting layer L12 overlap with each other. As a result, the functions of the transmitting region 13 and the non-transmitting region 14 can be reliably ensured by, for example, the transmitting layer L12 and the non-transmitting layer L11 being used, and thus the shape of the transmitting region 13 can be conspicuous with light in the display light-equipped transmitter 100 and the position of the display light-equipped transmitter 100 can be reliably displayed. In addition, for example, the transmitting layer L12 can be provided in both the transmitting region 13 and the non-transmitting region 14, and thus the display light-equipped transmitter 100 can be coated with the transmitting layer L12 and a sense of luxury can be produced for the display light-equipped transmitter 100.

In addition, by the front cover side engagement portion 18 and the component plate side front cover engagement portion 51 that engage the front cover 1 with the component plate 5 being provided, the front cover 1 and the component plate 5 can be, for example, temporarily fixed to each other. As a result, it is possible to provide the display light-equipped transmitter 100 that is assembled with ease.

The front cover fixing screw S11 fixing the front cover 1 to the component plate 5 by screwing is exposed to the outside of the display light-equipped transmitter 100 via the opening and closing opening portion 15 in a case where the display plate 16 is opened and is not exposed to the outside of the display light-equipped transmitter 100 via the opening and closing opening portion 15 in a case where the display plate 16 is closed. Accordingly, it is possible, for example, to operate the front cover fixing screw S11 by opening the display plate 16 or hide the front cover fixing screw S11 by closing the display plate 16, and thus the assembly can be further facilitated with the design of the display light-equipped transmitter 100 maintained. In addition, in a case where, for example, the front cover fixing screw S11 is provided in addition to the front cover side engagement portion 18 and the component plate side front cover engagement portion 51 described above, the front cover 1 and the component plate 5 can be fixed to each other by the front cover fixing screw S11 with the mutual rotation of the front cover 1 and the component plate 5 locked by the front cover side engagement portion 18 and the component plate side front cover engagement portion 51, and thus the display light-equipped transmitter 100 can be assembled with ease.

For example, “address information” is information on an address used for communication with the disaster prevention receiver and set in the display light-equipped transmitter 1100. “Disaster prevention receiver” is an external device monitoring and reporting a fire in the monitoring region. For example, “disaster prevention receiver” is a device electrically connected to at least the display light-equipped transmitter 1100. In addition, “operation guide information” is operation guiding information for the display light-equipped transmitter 1100. For example, “operation guide information” is procedure guiding information on the operation of the pressing spring 1043 for returning the protective plate 1042 in a pressed state to the original position of the protective plate 1042.

All of the information can be displayed in the first component plate side name plate portion 1051 by any method. For example, the model number, the firefighting certification number, and the rating of the light emitting unit 1003, which are text information for inspection, are displayed along with the operation guide information at a position facing the opening and closing opening portion 1015 in the thickness direction (Z direction) and the system information and the address information are displayed along with the date of manufacture and the serial number, which are text information for inspection, at a position facing the opening and closing opening portion 1015 in the thickness direction (Z direction) with the importance of each information piece and the like taken into account.

(Configuration-Details-Component Plate-Second Component Plate Side Name Plate Portion)

The second component plate side name plate portion 1052 is an inspection information display unit that displays at least the second inspection information out of the inspection information on the display light-equipped transmitter 1100. For example, the second component plate side name plate portion 1052 displays only the second inspection information. In addition, for example, the second component plate side name plate portion 1052 is similar in configuration to the first component plate side name plate portion 1051 except for the position and the shape of the second component plate side name plate portion 1052.

(Configuration-Details-Attachment Adapter)

The attachment adapter 1063 is provided with, for example, an adapter side opening portion 1631, component plate screwing holes 1632, and sheet metal screwing holes 1633 illustrated in FIG. 12.

(Configuration-Details-Attachment Adapter-Adapter Side Opening Portion)

The adapter side opening portion 1631 is an opening through which a part of the component plate 1005 is inserted. For example, the adapter side opening portion 1631 is an opening through which a part of the component plate 1005 protruding to the back side (−Z direction) is inserted and is provided in the vicinity of the center of the attachment adapter 1063.

(Configuration-Details-Attachment Adapter-Screwing Hole)

The component plate screwing hole 1632 is a screwing hole for attaching the component plate 1005 to the attachment adapter 1063. The sheet metal screwing hole 1633 is a screwing hole for attaching the attachment adapter 1063 to the sheet metal 1091.

(Assembly and Installation Methods)

Next, methods for assembling and installing the display light-equipped transmitter 1100 will be described.

First, the attachment adapter 1063 illustrated in FIG. 13 is attached to the sheet metal 1091 by any specific method. For example, the attachment is performed by an attachment adapter fixing screw (not illustrated) being continuously screwed into the sheet metal screwing hole 1633 in FIG. 12 and the sheet metal 1091 in a state where the adapter side opening portion 1631 in FIG. 12 is aligned with a sheet metal side opening portion 1911 for front side attachment in FIG. 13. The sheet metal side opening portion 1911 for front side attachment is an opening for attaching the display light-equipped transmitter 1100 from the front side of the sheet metal 1091. For example, the sheet metal side opening portion 1911 for front side attachment is an opening through which a part of the component plate 1005 protruding to the back side (−Z direction) is inserted.

Next, the component plate 1005 in FIG. 13 is attached to the attachment adapter 1063 by any specific method. For example, the attachment is performed by a component plate fixing screw S1011 being continuously screwed into the component plate 1005 and the component plate screwing hole 1632 illustrated in FIG. 12.

Next, the remaining components of the display light-equipped transmitter 1100 illustrated in FIG. 14 are attached to the component plate 1005 by any fixing unit (such as screwing with a screw, engagement with an engagement structure, and fitting with a fitting structure). The assembly and installation of the display light-equipped transmitter 1100 are completed as a result.

(Light Emission)

Next, the light emission by the display light-equipped transmitter 1100 will be described. Described here is, for example, the optical path of light in a case where the light emitting unit 1003 has emitted light to the light guide 1002.

First, the light emitted by the light emitting unit 1003 is incident on the light guide 1002 and guided to the entire light guide 1002. Subsequently, the light guided by the light guide 1002 is output to the outside of the display light-equipped transmitter 1100 that is on the front side of the display light-equipped transmitter 1100 via the transmitting region 1013 of the front cover 1001. In this case in particular, light emission is possible from the side surface portion 1012 as well as the front surface portion 1011 since the transmitting region 1013 in FIG. 11 is provided in the side surface portion 1012 as well as the front surface portion 1011 of the front cover 1001 as described above, and thus a user can visually recognize and confirm from every position on the front side of the display light-equipped transmitter 1100 that a part of the display light-equipped transmitter 1100 emits light in red.

(Notification Operation)

A notification operation will be described below. The display light-equipped transmitter 1100 provides notification of the outbreak of a fire by means of the notification operation. Described here is, for example, a notification operation in a case where a user has pressed the protective plate 1042 via the exposing opening portion 1017. This notification operation is similar to the notification operation in the related art, and thus only the outline of the notification operation will be described below.

In a case where a user presses the protective plate 1042 via the exposing opening portion 1017, the switch 1044 is pressed together with the protective plate 1042. As a result, the electric circuit of the transmitter board 1061 provides notification by transmitting a fire notification signal, which is a signal for fire notification, to the disaster prevention receiver via a communication line (not illustrated). The notification operation is performed in this manner.

(Effect of Shape of Transmitting Region)

As described above, the transmitting region 1013 illustrated in FIG. 10 is provided with the two-circular arc-shaped left transmitting region 1131 and right transmitting region 1132 in the lateral direction (X direction). As a result, the display light-equipped transmitter 1100 can be more conspicuous than in the case of single-point light emission by means of light emission at a plurality of points and it is possible to reliably meet predetermined standards requiring the lateral (X-direction) visibility of the display light-equipped transmitter 1100 (such as standards related to the Fire Services Act).

In addition, the upper non-transmitting region 1142 and the lower non-transmitting region 1143 face the light emitting unit 1003 in the front cover 1001 illustrated in FIG. 10. Accordingly, light blocking can be performed in the regions where mottles in terms of the state of light emission are likely to result from an increase in the light quantity of the light emitting unit 1003 by means of light blocking in the regions facing the light emitting unit 1003, and thus it is possible to cause the entire transmitting region 1013 of the front cover 1001 to emit light with uniformity and improve the design of the entire display light-equipped transmitter 1100 including the transmitting region 1013 emitting light. Especially, the region that faces the upper non-transmitting region 1142 and the lower non-transmitting region 1143 in the display light-equipped transmitter 1100 can be used for the light emitting unit 1003 to be provided, and thus the region where the light emitting unit 1003 is provided can be concentrated in two places. As a result, the display light-equipped transmitter 1100 can be compact by means of an effective use of the internal space of the display light-equipped transmitter 1100.

Effect of Embodiment 2

In the present embodiment, the transmitting region 1013 is provided in the front surface portion 1011 and the side surface portion 1012 as described above. Accordingly, it is possible, for example, to emit the light of the light emitting unit 1003 to both the front surface portion 1011 side and the side surface portion 1012 side, and thus users on the front and side surface sides of the display light-equipped transmitter 1100 can visually recognize the light and reliably recognize the position of the display light-equipped transmitter 1100.

In addition, the transmitting region 1013 is provided from the outer peripheral side of the front surface portion 1011 surrounding the center side non-transmitting region 1141 to the side surface portion 1012. Accordingly, for example, light can be continuously emitted from the front surface portion 1011 to the side surface portion 1012, and thus a user on a diagonal side between the front and side surface sides as well as users on the front and side surface sides of the display light-equipped transmitter 1100 can visually recognize light. As a result, users can further reliably recognize the position of the display light-equipped transmitter 1100.

In addition, the attachment adapter 1063 attaching the component plate 1005 to the sheet metal 1091 is provided between the sheet metal 1091 and the component plate 1005. Accordingly, for example, the display light-equipped transmitter 1100 can be attached from the front surface side to the sheet metal 1091, and thus no work is necessary on the back side of the sheet metal 1091 and the workability of the display light-equipped transmitter 1100 can be improved. In addition, for example, the amount of protrusion of the display light-equipped transmitter 1100 with respect to the sheet metal 1091 can be increased, and thus the visibility of the display light-equipped transmitter 1100 can be improved.

In addition, the first component plate side name plate portion 1051 and the second component plate side name plate portion 1052 displaying the inspection information are exposed to the outside of the display light-equipped transmitter 1100 in a case where the display plate 1016 is opened and are not exposed to the outside of the display light-equipped transmitter 1100 in a case where the display plate 1016 is closed. Accordingly, for example, the first component plate side name plate portion 1051 and the second component plate side name plate portion 1052 can be exposed only when necessary, and thus the inspection information can be visually recognized in a state where the appearance of the display light-equipped transmitter 1100 is kept simple and the inspection information can be displayed in a state where the design is maintained. As for previously proposed techniques for retrofitting a retrofit display light device into an existing transmitter in particular, inspection information is provided at a position that can be visually recognized only after the retrofit display light device is removed from the transmitter, and thus the retrofit display light device needs to be removed for inspection information confirmation and the removal is troublesome. In the case of the present application, however, the inspection information can be easily confirmed without the display light-equipped transmitter 1100 being removed or disassembled from the sheet metal 1091.

Embodiment 3

Next, Embodiment 3 will be described. Described in this embodiment is a case where the display light-equipped transmitter is attached from the back side of the attachment target. Embodiment 3 is substantially identical in configuration to Embodiment 2 unless otherwise stated. The same reference numerals as those used in Embodiment 2 are attached, as needed and without redundant description, to substantially identical configurations.

(Configuration)

The configuration of the display light-equipped transmitter according to the present embodiment will be described first. FIG. 17 is a perspective view of the display light-equipped transmitter that is attached to the sheet metal according to the present embodiment. FIG. 18 is a perspective view of the display light-equipped transmitter that is removed from the sheet metal. FIG. 19 is a front view of the display light-equipped transmitter. FIG. 20 is a side view of the display light-equipped transmitter. FIG. 21 is a rear view of the display light-equipped transmitter. FIG. 22 is a cross-sectional view taken along the B1-B1 arrow in FIG. 19. A state of being attached to a sheet metal 1092 is illustrated in FIGS. 17 and 19 to 22. The sheet metal 1092 is illustrated as having a rectangular shape for convenience of description.

A display light-equipped transmitter 1101 illustrated in each of the drawings is attached to the sheet metal 1092 of a fire hydrant box from the back side (−Z direction) as illustrated in FIG. 22. The display light-equipped transmitter 1101 is provided with, for example, the front cover 1001, the light guide 1002, the light emitting unit 1003, the display light board 1041, the protective plate 1042, the pressing spring 1043, the switch 1044, and the component plate 1005 illustrated in FIG. 14 and the transmitter board 1061, the board cover 1062, an attachment member 1071, and a cover packing 1072 illustrated in FIG. 22.

Here, the sheet metal 1092 is an attachment target similar to the sheet metal 1091 of Embodiment 2. Specifically, the sheet metal 1092 is a sheet metal of a fire hydrant box (overall configuration not illustrated) provided in the monitoring region. For example, the sheet metal 1092 partitions a front surface side region and a back side region from each other and is provided with a sheet metal side opening portion 1921 for back side attachment illustrated in FIGS. 19 and 22. “Front surface side region” is a partial region included in the monitoring region. Specifically, “front surface side region” is a region partitioned by the sheet metal 1092 and is a region on the front surface side (+Z direction) of the display light-equipped transmitter 1101 (that is, on the front surface side (+Z direction) of the sheet metal 1092). For example, “front surface side region” is a region outside the fire hydrant box. In addition, “back side region” is another partial region included in the monitoring region. Specifically, “back side region” is a region partitioned by the sheet metal 1092 and is a region on the back side (−Z direction) of the display light-equipped transmitter 1101 (that is, on the back side (−Z direction) of the sheet metal 1092). For example, “back side region” is a region in the fire hydrant box.

In addition, the sheet metal side opening portion 1921 for back side attachment is an opening provided in the sheet metal 1092. Specifically, the sheet metal side opening portion 1921 for back side attachment is an exposing hole for exposing at least a part of the display light-equipped transmitter 1101 to the front surface side region. For example, the sheet metal side opening portion 1921 for back side attachment is a circular hole smaller in diameter than the front cover 1001 of the display light-equipped transmitter 1101 (in other words, the display light-equipped transmitter 1101 is larger in diameter than the sheet metal side opening portion 1921 for back side attachment).

(Configuration-Attachment Member)

The attachment member 1071 in FIG. 22 causes the display light-equipped transmitter 1101 to be provided in the back side region. Specifically, the attachment member 1071 is an attachment unit that sandwiches at least a part of the display light-equipped transmitter 1101 with the sheet metal 1092 such that at least a part of the front cover 1001 is exposed to the front surface side region via the sheet metal side opening portion 1921 for back side attachment and for attaching the front cover 1001 to the sheet metal 1092. The attachment member 1071 can be of any specific type and configuration. For example, the attachment member 1071 has a rectangular shape larger than the front cover 1001 in the direction along the front surface portion 1011 of the front cover 1001. As an example, the attachment member 1071 is provided with an attachment member side opening portion 1711 illustrated in FIG. 21.

(Configuration-Attachment Member-Attachment Member Side Opening Portion)

The attachment member side opening portion 1711 is an opening through which a part of the component plate 1005 is inserted. For example, the attachment member side opening portion 1711 is an opening through which a part of the component plate 1005 protruding to the back side (−Z direction) is inserted and is provided in the vicinity of the center of the attachment member 1071.

(Configuration-Cover Packing)

The cover packing 1072 in FIG. 22 is a sealing unit. At least a part of the cover packing 1072 is provided around the sheet metal side opening portion 1921 for back side attachment between the sheet metal 1092 and the front cover 1001. Specifically, the cover packing 1072 provides sealing between the sheet metal 1092 and the front cover 1001. FIG. 23 is a diagram in which FIG. 22 is enlarged in part. The cover packing 1072 can be of any specific type and configuration. For example, the cover packing 1072 has an annular shape as a whole, the cover packing 1072 is provided along the side surface portion 1012 of the front cover 1001, at least a part of the cover packing 1072 is provided along a side slightly inside the edge of the front surface portion 1011 of the front cover 1001, and the cover packing 1072 is integrally configured by means of a material having at least two types of properties. As an example, the cover packing 1072 is provided with a main body portion 1721 and a cover portion 1722.

(Configuration-Cover Packing-Main Body Portion)

The main body portion 1721 is a part constituting a part of the cover packing 1072. Specifically, the main body portion 1721 extends in the thickness direction (Z direction). For example, the main body portion 1721 is a reflective and non-light-transmitting portion that reflects and does not pass light. In addition, the main body portion 1721 is relatively soft and elastically deformable. The main body portion 1721 can be molded by any method. For example, the main body portion 1721 is molded by any molding method (such as so-called two-color molding) by means of a soft, elastic, and non-light-transmitting material that reflects and does not pass light (such as a so-called elastomer material).

(Configuration-Cover Packing-Cover Portion)

The cover portion 1722 is a part constituting another part of the cover packing 1072. Specifically, the cover portion 1722 is provided on the front surface side of the main body portion 1721. For example, at least a part of the cover portion 1722 slightly protrudes to the front surface side region along the edge of the sheet metal side opening portion 1921 for back side attachment and via the sheet metal side opening portion 1921 for back side attachment. In addition, the cover portion 1722 is a light-transmitting portion passing light similarly to the transmitting region 1013 of the front cover 1001 and is relatively hard. The cover portion 1722 can be molded by any method. For example, the cover portion 1722 is molded by any molding method (such as so-called two-color molding) by means of a light-transmitting hard material passing light (such as a resin material).

(Assembly and Installation Methods)

Next, methods for assembling and installing the display light-equipped transmitter 1101 will be described.

First, the component plate 1005 is attached to the attachment member 1071 in FIG. 22 by any specific method. For example, the attachment is performed by a part of the component plate 1005 being inserted through the attachment member side opening portion 1711 and a component plate fixing screw S1021 being continuously screwed into the component plate 1005 and the attachment member 1071.

Next, the remaining components of the display light-equipped transmitter 1101 illustrated in FIG. 14 (other than the cover packing 1072) are attached to the component plate 1005 by any fixing unit (such as screwing with a screw, engagement with an engagement structure, and fitting with a fitting structure).

Next, the attachment member 1071 is attached to the sheet metal 1092 by any specific method. For example, as illustrated in FIG. 22, the attachment is performed by the display light-equipped transmitter 1101 being provided in the back side region after the cover packing 1072 is provided around the front cover 1001, positioning being performed such that the front cover 1001 is exposed via the sheet metal side opening portion 1921 for back side attachment, and an attachment fitting A1011 being used. Here, the attachment fitting A1011 is an attachment member attachment unit that attaches the attachment member 1071 to the sheet metal 1092 and is fixed to both the attachment member 1071 and the sheet metal 1092 by any fixing unit (such as screwing with a screw and adhesion with an adhesive material). For example, the attachment fitting A1011 is a bent and fixed fitting. The assembly and installation of the display light-equipped transmitter 1101 are completed as a result.

(Light Emission)

Next, the light emission by the display light-equipped transmitter 1101 will be described. Described here is, for example, the optical path of light in a case where the light emitting unit 1003 has emitted light to the light guide 1002.

The light emitted by the light emitting unit 1003 is output from the transmitting region 1013 of the front cover 1001 to the front surface side region via the light guide 1002 as in the case of Embodiment 2. In this case, part of the light is directly output from the transmitting region 1013 to the front surface side region, some of the rest of the light is transmitted through the cover portion 1722 of the cover packing 1072 and output, and the remaining part of the light is reflected at the inner periphery of the main body portion 1721 in the cover packing 1072 and output.

In this case, in particular, a part of the cover portion 1722 of the cover packing 1072 protrudes to the front surface side region, and thus a user can visually recognize and confirm from every position in the front surface side region that a part of the display light-equipped transmitter 1101 emits light in red.

Effect of Embodiment 3

In the present embodiment, the display light-equipped transmitter 1101 is provided in the back side region and is larger in diameter than the sheet metal side opening portion 1921 for back side attachment as described above. In addition, the display light-equipped transmitter 1101 is attached such that at least a part of the front cover 1001 is exposed to the front surface side region via the sheet metal side opening portion 1921 for back side attachment. Accordingly, for example, the display light-equipped transmitter 1101 can be attached such that the sheet metal 1091 is flat in the front surface side region, and thus it is possible to prevent the display light-equipped transmitter 1101 from acting as a hindrance. In addition, for example, the sheet metal side opening portion 1921 for back side attachment can be sealed by the display light-equipped transmitter 1101 and it is possible to prevent a contaminant such as rain and dust from entering the back side region via the exposing hole since the display light-equipped transmitter 1101 is larger in diameter than the sheet metal side opening portion 1921 for back side attachment.

In addition, by the cover packing 1072 being provided, it is possible, for example, to reliably prevent a contaminant such as rain and dust from entering the back side region via the sheet metal side opening portion 1921 for back side attachment.

In addition, the board cover side name plate portion 1621 illustrated in FIG. 15, which displays the connection-related information, is provided so as to be exposed on the back side (−Z direction) of the display light-equipped transmitter 1101. Accordingly, for example, the connection-related information can be visually recognized in a state where the appearance of the front surface side (+Z direction) of the display light-equipped transmitter 1101 is kept simple and the connection-related information can be displayed in a state where the design is maintained. As for previously proposed techniques for retrofitting a retrofit display light device into an existing transmitter in particular, the transmitter is embedded in an attachment target although connection-related information is displayed on the back side of the transmitter, and thus the retrofit display light device and the transmitter need to be removed for connection-related information confirmation and the removal is troublesome. In the case of the present application, however, the connection-related information can be easily confirmed by the display light-equipped transmitter 1101 going around into the back side region without being removed or disassembled from the attachment target in a case where the display light-equipped transmitter 1101 is provided in the back side region and attached such that at least a part of the front cover 1001 is exposed to the front surface side region via the sheet metal side opening portion 1921 for back side attachment.

Regarding Front Cover of Embodiment 1 (No. 2)

In addition, in Embodiment 1, the configurations of the non-transmitting layer L11 and the transmitting layer L12 of the front cover 1 may be changed in any manner. For example, the transmitting layer L12 may overlap with the non-transmitting layer L11 from the back side (−Z direction). In another example, the non-transmitting region 14 of the front cover 1 may be configured with only the non-transmitting layer L11 provided and without the non-transmitting layer L11 and the transmitting layer L12 overlapping with each other by the transmitting layer L12 overlapping with only a part of the non-transmitting layer L11 or the transmitting layer L12 not overlapping with the non-transmitting layer L11. In this case, any size relationship may be applied between the areas of the non-transmitting layer L11 and the transmitting layer L12.

Regarding Light Guide of Embodiment 1

In addition, in Embodiment 1, the overall configuration of the light guide 2 may be changed in any manner. For example, the light guide 2 may be divided into any number and configured as two or more light guides. In another example, the light guide 2 may have any non-annular shape (such as a triangular shape and a rectangular shape).

Regarding Attachment of Display Light-equipped Transmitter of Embodiment 1

In addition, the display light-equipped transmitter 100 of Embodiment 1 may be attached to the sheet metal 91 in any manner. Specifically, the display light-equipped transmitter 100 may be attached from the front surface side (+Z direction) to the sheet metal 91 via any attachment adapter or may be attached from the back side (−Z direction) to the sheet metal 91 by any means.

Regarding Front Cover of Embodiments 2 and 3

In addition, in Embodiments 2 and 3, the configurations of the transmitting region 1013 and the non-transmitting region 1014 of the front cover 1001 may be changed in any manner. For example, the transmitting region 1013 may be provided in only one of the front surface portions 1011 and the side surface portion 1012. In addition, the transmitting region 1013 may have any shape insofar as the transmitting region 1013 is not annular.

Regarding Light Guide of Embodiments 2 and 3

In addition, in Embodiments 2 and 3, the overall configuration of the light guide 1002 may be changed in any manner. For example, the light guide 1002 may be divided into any number and configured as two or more light guides. In another example, the light guide 1002 may have any non-annular shape (such as a triangular shape and a rectangular shape).

Regarding Attachment of Display Light-equipped Transmitters of Embodiments 2 and 3 (No. 1)

In addition, direct attachment to the sheet metal 1091 may be performed with the attachment adapter 1063 omitted with regard to the display light-equipped transmitter 1100 of Embodiment 2. Direct attachment to the sheet metal 1092 may be performed with the cover packing 1072 omitted with regard to the display light-equipped transmitter 1101 of Embodiment 3. Specifically, the attachment may be performed by any fixing unit (such as screwing with a screw, engagement with an engagement structure, and fitting with a fitting structure) in this case.

Regarding Attachment of Display Light-equipped Transmitters of Embodiments 2 and 3 (No. 2)

In addition, the display light-equipped transmitter 1100 of Embodiment 2 may be attached flat to the sheet metal 1091 by being embedded in the sheet metal 1091.

Effects of Embodiments 2 and 3

In addition, for example, the display light-equipped transmitters 1100 and 1101 described in Embodiments 2 and 3 (configurations illustrated in FIGS. 14 and 15 to be specific) can be attached from the front surface sides (+Z direction) and the back sides (−Z direction) of the sheet metals 1091 and 1092 as targets to which the display light-equipped transmitters 1100 and 1101 are attached. In other words, light can be output to the side surface side as well, by the side surface portion 1012 being exposed, in a case where attachment is performed from the front surface side (+Z direction) as in the display light-equipped transmitter 1100 of Embodiment 2 and the light from the side surface portion 1012 can be reflected by the inner periphery of the main body portion 1721 to be output to the side surface side as well via a part of the cover portion 1722 protruding to the front surface side region in a case where attachment is performed from the back side (−Z direction) as in the display light-equipped transmitter 1101 of Embodiment 3, and thus attachment from the front surface side (+Z direction) and attachment from the back side (−Z direction) are possible and displayability can be improved.

Regarding Interpretation of Term of Display Light-equipped Transmitter in Embodiments 2 and 3

In addition, regarding the term of “display light-equipped transmitter”, configurations common to Embodiments 2 and 3 may be interpreted as “display light-equipped transmitter”, configurations used only in Embodiment 2 may be interpreted as configurations optionally used for front surface side attachment, or configurations used only in Embodiment 3 may be interpreted as configurations optionally used for back side attachment. As for “display light-equipped transmitter” including the configurations common to Embodiments 2 and 3 and pertaining to this case of interpretation, the display light-equipped transmitter is attached to the attachment target from the front surface side (+Z direction) or the back side (−Z direction), and thus the display light-equipped transmitter can be, for example, attached from the front surface side (+Z direction) to the attachment target so as to protrude as in Embodiment 2 or attached flat to the attachment target from the back side (−Z direction). As a result, the display light-equipped transmitter can be adapted to an attachment environment and it is possible to improve the visibility of the display light-equipped transmitter or prevent the display light-equipped transmitter from acting as a hindrance.
