[0009] The emergency broadcast system 1 according to the embodiment of the present disclosure will be described in detail with reference to the drawings. Note that each figure described in the following embodiment is a schematic diagram, and the ratio of the size and thickness of each component in each figure does not necessarily reflect the actual dimensional ratio. In addition, the embodiment and modified example described below are merely examples of the present disclosure, and the present disclosure is not limited to the embodiment and modified example. Even if it is not the embodiment and modified example, various modifications are possible according to the design, etc., as long as it does not deviate from the technical idea of ​​the present disclosure. In addition, the following embodiment (including modified examples) may be realized by appropriately combining them.

[0010] (1) Overview First, an overview of an emergency broadcast system 1 according to this embodiment will be described with reference to FIG.

[0011] The emergency broadcast system 1 is a system for dealing with abnormalities (disasters, etc.) in facilities such as tenant buildings. Note that the term "facility" in this disclosure includes not only tenant buildings, but also theaters, movie theaters, public halls, amusement parks, complexes, restaurants, department stores, schools, hotels, inns, hospitals, nursing homes, kindergartens, libraries, museums, art galleries, underground shopping malls, stations, airports, apartment complexes, etc. Also, the term "disaster" in this disclosure includes, for example, fires, gas leaks, earthquakes, flooding, etc.

[0012] As shown in FIG. 3, the emergency broadcast system 1 includes a housing 14 and an emergency broadcast unit 6. The emergency broadcast unit 6 is stored in the housing 14 and has an emergency broadcast function. The housing 14 includes a main body 15 and a lid 16. The main body 15 has an opening 15a and an emergency broadcast unit storage section 152. The emergency broadcast unit storage section 152 stores the emergency broadcast unit 6 introduced through the opening 15a. The lid 16 covers the opening 15a of the main body 15. The emergency broadcast unit 6 has a connection section 612 to which wiring is connected. The connection section 612 is disposed on the portion of the emergency broadcast unit 6 on the opening 15a side when the emergency broadcast unit 6 is stored in the emergency broadcast unit storage section 152.

[0013] According to this configuration, the connection portion 612 of the emergency broadcast unit 6 is disposed on the side of the opening 15a of the emergency broadcast unit 6 when the emergency broadcast unit 6 is stored in the emergency broadcast unit storage portion 152. Therefore, the wiring connection work of the emergency broadcast unit 6 stored in the emergency broadcast unit storage portion 152 can be performed from the opening 15a side of the main body portion 15 of the housing 14. This improves the workability of the wiring connection work of the emergency broadcast unit 6.

[0014] (2) Detailed configuration (2.1) Emergency Broadcast System Configuration The configuration of the emergency broadcast system 1 will be described in more detail below with reference to the drawings.

[0015] As shown in FIG. 1, the emergency broadcast system 1 includes multiple sensors 2, a display unit 3, an operation unit 4, a receiver unit 5, an emergency broadcast unit 6, multiple speakers 7, multiple amplifiers 8, an emergency telephone device 9, a microphone 13 for emergency broadcasts, and a power supply unit 10.

[0016] The multiple sensors 2 are installed at multiple different locations in the facility, detect abnormalities (e.g., fires) that occur at the multiple locations, and transmit the detection results to the receiver unit 5. As an example, the multiple sensors 2 are fire sensors that detect the occurrence of a fire in the facility from at least one of smoke concentration and temperature.

[0017] The display unit 3 is a display device for presenting various information to a user of the emergency broadcast system 1. The display unit 3 includes, for example, a liquid crystal display or an organic EL (Electro-Luminescence) display. The display unit 3 displays information on the location of an abnormality that has occurred within the facility, for example, in response to the control of the receiver unit 5.

[0018] The operation unit 4 is a device that accepts operations from a user of the emergency broadcast system 1. The operation unit 4 accepts operations (control operations) for controlling the receiver unit 5, the emergency broadcast unit 6, and the display unit 3. The control operations include a first operation, a second operation, and a third operation. The first operation is an operation for controlling the receiver unit 5 to report the detection result of the detector 2 from the speaker 7 and stop the reporting. The second operation is an operation for controlling the emergency broadcast unit 6 to make an emergency broadcast from the speaker 7 and stop the emergency broadcast. The third operation is an operation for controlling the display unit 3 to display various information and stop the display.

[0019] The receiver unit 5 is a unit having a function of a receiver. As a function of the receiver, the receiver unit 5 acquires detection results from each of the multiple sensors 2, and judges whether or not an abnormality has occurred in the facility based on the acquired detection results. More specifically, the receiver unit 5 judges whether or not each sensor 2 has detected a fire (abnormality) based on the acquired detection results. More specifically, the receiver unit 5 judges which of multiple levels the level of the fire is based on the acquired detection results. The multiple levels include a safety level, a precursor level, and an alarm level. The safety level is a level corresponding to a state in which the sensor 2 has not detected a precursor phenomenon that is a precursor of a fire. The precursor level is a level corresponding to a state in which the sensor 2 has detected a precursor phenomenon that is a precursor of a fire. The alarm level is a level corresponding to a state in which the sensor 2 has detected a fire and is operating. Note that the sensor 2 being operating indicates that when the sensor 2 detects the occurrence of a fire, the sensor 2 transmits the detection result to the receiver unit 5.

[0020] Furthermore, as a function of the receiver, when it determines that an abnormality has occurred within the facility, the receiver unit 5 displays on the display 3 information regarding the location where the abnormality has occurred (i.e., the location of the detector 2 that detected the abnormality) and the level of the abnormality (safety level, warning level, and alarm level).

[0021] Furthermore, as a function of the receiver, when the operation unit 4 accepts the control operation, the receiver unit 5 controls the multiple speakers 7 based on the control operation. For example, when the operation unit 4 accepts the first operation as the control operation, the receiver unit 5 controls the multiple speakers 7 to notify the detection result of the detector 2 from the multiple speakers 7 or to stop the notification.

[0022] The emergency broadcast unit 6 is a unit having an emergency broadcast function. As an emergency broadcast function, the emergency broadcast unit 6 causes the multiple speakers 7 to make an emergency broadcast based on the judgment result of the receiver unit 5. More specifically, when the receiver unit 5 judges that the level of the fire is a precursor level, the emergency broadcast unit 6 causes the multiple speakers 7 to make, for example, an attention broadcast to call attention as an emergency broadcast. Also, when the receiver unit 5 judges that the level of the fire is an alarm level, the emergency broadcast unit 6 causes the multiple speakers 7 to make, for example, an alarm broadcast regarding the occurrence of a fire as an emergency broadcast. The alarm broadcast includes, for example, broadcasting information indicating that the detector 2 has detected a fire and information regarding response actions to deal with the occurred fire.

[0023] When the operating section 4 is operated, for example, so that the emergency broadcast unit 6 makes an emergency broadcast, as described above, the emergency broadcast function of the emergency broadcast unit 6 causes the multiple speakers 7 to make an emergency broadcast based on the judgment result of the receiver unit 5.

[0024] Furthermore, as an emergency broadcast function, the emergency broadcast unit 6 outputs a voice input to an emergency broadcast microphone 13 from a plurality of speakers 7. The microphone 13 is disposed on the front surface of the cover portion 16, for example.

[0025] The multiple speakers 7 are output devices for making emergency broadcasts under the control of the emergency broadcast unit 6 when an abnormality (for example, a fire) occurs within the facility. The multiple speakers 7 are arranged in different locations within the facility.

[0026] The multiple amplifiers 8 are amplifiers for amplifying the outputs of the multiple speakers 7. The multiple amplifiers 8 correspond one-to-one to the multiple speakers 7, and amplify the outputs of the corresponding speakers 7. The amplifiers 8 amplify the emergency broadcast signals output from the emergency broadcast unit 6 to the corresponding speakers 7, and output the amplified emergency broadcast signals to the corresponding speakers 7.

[0027] The emergency telephone device 9 is a communication device capable of communicating with multiple (e.g., two) telephone handsets 101, 102 installed in the facility. The emergency telephone device 9 is used for the purpose of notifying or confirming the circumstances of the abnormality when any of the multiple sensors 2 detects an abnormality. The emergency telephone device 9 is used, for example, when a manager checks the circumstances of the abnormality with facility users or facility staff who are present at the scene where the abnormality occurred. The multiple telephone handsets 101, 102 are installed in multiple different locations in the facility. The emergency telephone device 9 is capable of communicating with the multiple telephone handsets 101, 102.

[0028] More specifically, the emergency telephone device 9 includes a telephone base unit 91 and an emergency telephone unit 93. The telephone base unit 91 corresponds to a plurality of telephone handsets 101, 102, and is a base unit for making calls between the corresponding telephone handsets. The emergency telephone unit 93 is a control device that controls calls between the telephone base unit 91 and the plurality of telephone handsets 101, 102. The emergency telephone unit 93 is disposed, for example, in a power supply unit 10 described later. More specifically, the emergency telephone unit 93 is disposed inside at least one of a first power supply unit 11 described later and a second power supply unit 12 described later (for example, the first power supply unit 11). The telephone base unit 91 is disposed, for example, on the front surface of the cover portion 16.

[0029] The emergency broadcast microphone 13 is a sound collecting device for collecting the voice of the user. The voice collected by the microphone 13 is output from the multiple speakers 7. As a result, when a user wishes to convey a certain matter to people at various locations in the facility during an emergency broadcast, the user can input the certain matter into the microphone 13 and have the certain matter conveyed to people at various locations in the facility by voice output from the multiple speakers 7. The microphone 13 is disposed, for example, on the front surface of the cover 16. The microphone 13 is controlled, for example, by the emergency broadcast unit 6.

[0030] The power supply unit 10 supplies power to each component of the emergency broadcast system 1 (the receiver unit 5, the emergency broadcast unit 6, the emergency telephone device 9, the display unit 3, etc.). The power supply unit 10 converts AC power supplied from an AC power source into DC power, transforms the converted DC power to a predetermined voltage, and supplies the transformed DC power to each component of the emergency broadcast system 1.

[0031] The power supply unit 10 includes a first power supply unit 11 and a second power supply unit 12 .

[0032] The first power supply unit 11 is a power supply unit for supplying power to the receiver unit 5. In this embodiment, the first power supply unit 11 also supplies power to the display unit 3 and the emergency telephone device 9, for example, via the receiver unit 5. The first power supply unit 11 converts AC power supplied from an AC power source into DC power, transforms the voltage of the converted DC power to a predetermined voltage, and supplies the transformed DC power to the receiver unit 5, the display unit 3, and the emergency telephone device 9.

[0033] In this embodiment, an emergency telephone unit 93 is disposed in the first power supply unit 11. That is, the first power supply unit 11 also serves as the emergency telephone unit 93.

[0034] The second power supply unit 12 is a power supply unit for supplying power to the emergency broadcast unit 6. In this embodiment, the second power supply unit 12 also supplies power to the multiple amplifiers 8 and the microphone 13, for example, via the emergency broadcast unit 6. The second power supply unit 12 converts AC power supplied from an AC power supply into DC power, transforms the voltage of the converted DC power to a predetermined voltage, and supplies the transformed DC power to the emergency broadcast unit 6, the multiple amplifiers 8, and the microphone 13.

[0035] (2.2) Structure of emergency broadcast system The structure of the emergency broadcast system 1 will be described in more detail below with reference to the drawings. Below, the top, bottom, left, right, front and back of the emergency broadcast system 1 are defined as shown in FIG. 2. In FIG. 2, the lid 16 side of the housing 14 is defined as the front side of the emergency broadcast system 1, and the side opposite the lid 16 side is defined as the rear side of the emergency broadcast system 1. The left and right sides as viewed from the housing 14 are defined as the left and right sides of the emergency broadcast system 1, respectively. The upper and lower sides as viewed from the housing 14 are defined as the upper and lower sides of the emergency broadcast system 1, respectively.

[0036] (2.2.0) Housing 2 and 3, the emergency broadcast system 1 further includes a housing 14. The housing 14 is an outer shell that houses each component (the display unit 3, the operation unit 4, the receiver unit 5, the emergency broadcast unit 6, the multiple amplifiers 8, the emergency telephone device 9, and the power supply unit 10) of the emergency broadcast system 1. The housing 14 is, for example, in the shape of a rectangular parallelepiped (for example, a vertically elongated rectangular parallelepiped) box.

[0037] The housing 14 includes a main body portion 15 and a cover portion 16 .

[0038] The main body 15 is a rectangular parallelepiped (e.g., vertically elongated rectangular parallelepiped) box having an opening 15a (see FIG. 3) on the front side. The main body 15 is formed, for example, from metal. The main body 15 has an upper wall 15U, a left wall 15L, a right wall 15R, a rear wall 15B, and a bottom wall 15D. The opening 15a functions as an inlet for introducing each component (the receiver unit 5, the emergency broadcast unit 6, the multiple amplifiers 8, and the power supply unit 10) into the inside of the main body 15. The opening 15a is formed on the entire front side of the main body 15.

[0039] The main body 15 has an amplifier storage section 151, an emergency broadcast unit storage section 152, a receiver unit storage section 153, a power supply unit storage section 154, and an emergency telephone unit storage section 155 (see FIG. 3). Each storage section (the amplifier storage section 151, the emergency broadcast unit storage section 152, the receiver unit storage section 153, the power supply unit storage section 154, and the emergency telephone unit storage section 155) is disposed inside the opening 15a, and is arranged side by side in the longitudinal direction (up-down direction) of the main body 15.

[0040] (2.2.1) Amplifier storage As shown in FIG. 3, the amplifier storage section 151 is a storage section that stores a plurality of amplifiers 8. The amplifier storage section 151 is located at the topmost position inside the main body section 15. In other words, the amplifier storage section 151 is disposed above the emergency broadcast unit 6 described below. The amplifier storage section 151 is configured by the lower surface of the upper wall 15U of the main body section 15, the upper part of the front surface of the rear wall 15B, the upper part of the inner surface of the left wall 15L, and the upper part of the inner surface of the right wall 15R. In the example of FIG. 3, the amplifier storage section 151 is configured vertically long so that a plurality of amplifiers 8 can be stored vertically lined up.

[0041] Each of the multiple amplifiers 8 is stored in the amplifier storage section 151 and fixed, for example, by being screwed to the rear surface 151a (see FIG. 4) of the amplifier storage section 151 (i.e., the front surface of the rear wall 15B of the main body section 15).

[0042] More specifically, as shown in FIG. 4, each of the amplifiers 8 has a circuit section that performs the functions of the amplifier 8 and a housing 81 that houses the circuit section. The housing 81 has a housing main body 81a and a pair of fixing pieces 81b. The housing main body 81a is a portion that houses the circuit section, and is, for example, a rectangular box shape. The pair of fixing pieces 81b are portions that are fixed to the back surface 151a of the amplifier storage section 151 by screwing. The pair of fixing pieces 81b are provided on the housing main body 81a so as to protrude outward in the left-right direction from the rear edges of the left and right side surfaces of the housing main body 81a. Each fixing piece 81b is provided with an insertion hole 81c through which a screw N1 for screwing is inserted. On the other hand, the back surface 151a of the amplifier storage section 151 is provided with a screw hole E1 through which the screw N1 is screwed.

[0043] Each of the multiple amplifiers 8 is arranged in the amplifier storage section 151 such that the rear surface of the housing 81 of the amplifier 8 contacts the rear surface 151a of the amplifier storage section 151. In this arranged state, a screw N1 is inserted from the front side through the insertion hole 81c of the fixing piece 81b and screwed into the screw hole E1 in the rear surface 151a of the amplifier storage section 151. In other words, the fixing piece 81b is fixed to the rear surface 151a of the amplifier storage section 151 by the screw N1. As a result, each of the multiple amplifiers 8 is stored in the amplifier storage section 151.

[0044] (2.2.2) Emergency broadcast unit storage area 3, the emergency broadcast unit storage section 152 is a storage section that stores the emergency broadcast unit 6. The emergency broadcast unit storage section 152 is located below the amplifier storage section 151. The emergency broadcast unit storage section 152 is configured by the upper central part of the front surface of the rear wall 15B, the upper central part of the inner surface of the left wall 15L, and the upper central part of the inner surface of the right wall 15R.

[0045] The emergency broadcast unit 6 is stored by being inserted from the opening 15a of the main body 15 toward the back side of the emergency broadcast unit storage section 152.

[0046] More specifically, the emergency broadcast unit 6 has a plurality of component units 61 having at least a part of the emergency broadcast function. That is, the emergency broadcast function is distributed and configured among the plurality of component units 61. Each of the plurality of component units 61 is, for example, a rectangular plate. In the example of FIG. 3, the plurality of component units 61 are divided into a plurality of stages (for example, two stages) in the vertical direction and stored in the emergency broadcast unit storage section 152. In each stage, each component unit 61 is inserted into the emergency broadcast unit storage section 152 in an upright position in the vertical direction, and is stored in a state where it is lined up with an interval in the thickness direction (left-right direction) of the component unit 61.

[0047] More specifically, as shown in FIG. 5, the emergency broadcast unit storage section 152 has a plurality of (for example, two) storage shelves 20 arranged in a vertical direction.

[0048] The storage shelves 20 correspond one-to-one to the above-mentioned stages, and store the configuration units 61 stored in the corresponding stages. Each storage shelf 20 is a rectangular box having an opening 20a on the front side. Each storage shelf 20 has an upper plate portion 20U, a lower plate portion 20D, a left plate portion 20L, a right plate portion 20R, and a rear plate portion 20B.

The front end surface 20d of the lower plate portion 20D is provided with a plurality of screw holes 20e into which fixing pieces 614b (described later) of each of the plurality of constituent units 61 are screwed.

[0050] The multiple pairs of guide parts 21 correspond one-to-one to the multiple constituent units 61 stored in the storage shelf 20, and guide the corresponding constituent units 61 from the opening 20a of the storage shelf 20 to the back of the storage shelf 20. The multiple guide parts 21 are arranged in the storage shelf 20 at locations where the corresponding constituent units 61 are stored.

[0051] More specifically, each pair of guide parts 21 has an upper guide part 21a and a lower guide part 21b. The upper guide part 21a is disposed on the lower surface of the upper plate part 20U, and the lower guide part 21b is disposed on the upper surface of the lower plate part 20D. The upper guide part 21a has an upper groove part extending from one end to the other end in the longitudinal direction (front-rear direction) of the upper guide part 21a. The lower guide part 21b has a lower groove part extending from one end to the other end in the longitudinal direction (front-rear direction) of the lower guide part 21b. The upper side part and the lower side part of the constituent unit 61 are slidably fitted into the upper groove part of the upper guide part 21a and the lower groove part of the lower guide part 21b, respectively, so that each pair of guide parts 21 guides the corresponding constituent unit 61 from the opening part 20a of the storage shelf 20 to the back of the storage shelf 20.

[0052] The lower guide portions 21b of the pairs of guide portions 21 are arranged at intervals from each other in the left-right direction (the direction in which the left plate portion 20L and the right plate portion 20R are aligned) on the upper surface of the lower plate portion 20D. The upper guide portion 21a of each of the pairs of guide portions 21 is arranged directly above the lower guide portion 21b that constitutes the pair on the lower surface of the upper plate portion 20U.

[0053] The main board 22 is disposed on the front surface of the rear plate portion 20B of the storage shelf 20. The main board 22 is, for example, a rectangular plate. The main board 22 is disposed on the front surface of the rear plate portion 20B with the rear surface of the main board 22 overlapping the front surface of the rear plate portion 20B.

[0054] The multiple power connectors 23 correspond one-to-one to the multiple configuration units 61 stored in the storage shelf 20, and are connectors for connecting to power connection parts 613 (described below) of the corresponding configuration units 61. The multiple power connectors 23 supply power from the power supply unit 10 to the corresponding configuration units 61 stored in the storage shelf 20.

[0055] The multiple power connectors 23 are arranged at intervals from one another in the left-right direction (the direction in which the left plate portion 20L and the right plate portion 20R are aligned) on the front surface of the main board 22. Each of the multiple power connectors 23 is arranged at a position on the front surface of the main board 22 corresponding to the storage location of the corresponding component unit 61. The connection surface of each of the multiple power connectors 23 faces forward.

[0056] 6, each of the multiple configuration units 61 has a circuit board 611, a connection portion 612, a power supply connection portion 613, and a fixed portion 614. The connection portion 612, the power supply connection portion 613, and the fixed portion 614 correspond to the configuration unit 61 having these respective portions (the connection portion 612, the power supply connection portion 613, and the fixed portion 614). The multiple configuration units 61 are in one-to-one correspondence with the multiple power supply connectors 23.

[0057] The circuit board 611 is a board on which various electronic components to be mounted in the structural unit 61 are mounted. The circuit board 611 is provided with wiring for electrically connecting the various electronic components. The circuit board 611 is, for example, in the shape of a rectangular plate. The circuit board 611 has a first main surface 611a and a second main surface 611b on both sides in the thickness direction of the circuit board 611.

[0058] The connection portion 612 is a portion to which a plurality of wires are connected. The plurality of wires include wires from the corresponding configuration unit 61, wires from other configuration units 61, wires from each amplifier 8, and wires from the receiver unit 5.

[0059] The connection part 612 is disposed on a portion (e.g., end) 611s on one side (front side) of the first main surface 611a of the circuit board 611. The "one side" refers to the opening 20a side (i.e., opening 15a side) of the storage shelf 20 of the component unit 61 when the component unit 61 is stored in the storage shelf 20 (i.e., the emergency broadcast unit storage section 152). The connection surface 612g of the connection part 612 faces the one side. More specifically, the connection part 612 has a plurality of connection holes 612a to which the plurality of wirings are connected. The plurality of connection holes 612a are disposed, for example, lined up in the vertical direction on the connection surface 612g of the connection part 612.

[0060] 6, the portion 611s is an end portion of the one side (front side) of the first main surface 611a of the circuit board 611. However, the portion 611s may be within a range from one side (front side) of the one side (front side) of the first main surface 611a to a position about one-third of the front-to-rear length of the first main surface 611a toward the opposite side (rear side). This range is assumed to be a range within which the hand of a worker can reach the connection portion 612 when wiring the connection portion 612 from the opening 15a side of the main body 15.

[0061] The power connection part 613 is a part that is detachably connected to a corresponding power connector 23 in the storage shelf 20. The component unit 61 operates with power supplied from the power connection part 613. The power connection part 613 is disposed in a part (e.g., an end part) 611t on the first main surface 611a of the circuit board 611 opposite to the one side (rear side). The connection surface of the power connection part 613 faces the opposite side to the one side. In other words, the power connection part 613 is disposed in a part 611t of the emergency broadcast unit 6 on the side in the insertion direction of the emergency broadcast unit 6 into the emergency broadcast unit storage part 152.

[0062] The fixing portion 614 is a portion for fixing the structural unit 61 to the storage shelf 20 (i.e., the emergency broadcast unit storage section 152). The fixing portion 614 is disposed in a portion (e.g., an end portion) of the first main surface 611a of the circuit board 611 on the one side (front side) described above.

[0063] More specifically, the fixing portion 614 is, for example, in the shape of a rectangular plate. The fixing portion 614 has a fixing portion main body 614a and a pair of fixing pieces 614b.

[0064] The fixing part main body 614a is, for example, plate-shaped (for example, rectangular plate-shaped). The fixing part main body 614a is arranged, for example, by screwing, in the above-mentioned one side portion (for example, end portion) 611s of the first main surface 611a of the circuit board 611 in a state where it stands perpendicular to the first main surface 611a. The fixing part main body 614a has a notch 614c. The notch 614c is cut out in a concave shape from the end portion on the circuit board 611 side toward the opposite end portion in the fixing part main body 614a. The notch 614c is a portion where the connecting part 612 is arranged in a fitted state. The notch 614c is formed in a rectangular shape of the same shape and size as the connecting part 612.

[0065] The pair of fixing pieces 614b protrude in the vertical direction from both ends in the vertical direction of the fixing portion main body 614a. More specifically, the pair of fixing pieces 614b protrude in the vertical direction from both ends in the vertical direction (upper side and lower side) of the circuit board 611. Each fixing piece 614b is provided with an insertion hole 614d through which a screw is inserted.

[0066] Next, a procedure for storing the component unit 61 will be described with reference to FIGS.

[0067] The component unit 61 is inserted into the storage shelf 20 from the power supply connection portion 613 side with the circuit board 611 standing upright in the vertical direction. More specifically, the component unit 61 is inserted from the opening 20a of the storage shelf 20 between a pair of corresponding guide portions 21 (upper guide portion 21a and lower guide portion 21b) in the storage shelf 20. At this time, the upper side portion of the circuit board 611 is fitted into the upper groove portion of the upper guide portion 21a and guided along the upper guide portion 21a. Also, the lower side portion of the circuit board 611 is fitted into the lower groove portion of the lower guide portion 21b and guided along the lower guide portion 21b. As a result, the component unit 61 is guided by the pair of guide portions 21 and inserted to the back of the storage shelf 20.

[0068] When the configuration unit 61 is inserted to the back of the storage shelf 20, the power connection portion 613 of the configuration unit 61 is connected to the power connector 23 of the storage shelf 20. Furthermore, a pair of fixing pieces 614b of the fixing portion 614 of the configuration unit 61 contact the front end surface 20b of the upper plate portion 20U and the front end surface 20d of the lower plate portion 20D of the storage shelf 20. Then, the screw N2 is inserted through the insertion hole 614d of the upper fixing piece 614b and screwed into the screw hole 20c of the front end surface 20b. Furthermore, the screw N3 is inserted through the insertion hole 614d of the lower fixing piece 614b and screwed into the screw hole 20e of the front end surface 20d. As a result, the pair of fixing pieces 614b of the configuration unit 61 are fixed to the front end surface 20b of the upper plate portion 20U and the front end surface 20d of the lower plate portion 20D of the storage shelf 20. In this manner, the constituent unit 61 is stored in the storage shelf 20.

[0069] (2.2.3) Receiver unit storage compartment 3, the receiver unit storage section 153 is a storage section that stores the receiver unit 5. The receiver unit storage section 153 is located below the emergency broadcast unit storage section 152. The receiver unit storage section 153 is configured by the lower central part of the front surface of the rear wall 15B, the lower central part of the inner surface of the left wall 15L, and the lower central part of the inner surface of the right wall 15R.

[0070] The receiver unit 5 is stored in the receiver unit storage section 153 by being inserted from the opening 15a of the main body 15 toward the back side of the receiver unit storage section 153.

[0071] More specifically, the receiver unit 5 has a plurality of component units 51 each having at least a part of the receiver function of the receiver unit 5. That is, the receiver function of the receiver unit 5 is distributed and configured among the plurality of component units 51. Each of the plurality of component units 51 is, for example, in the form of a rectangular plate. The plurality of component units 51 are inserted into the receiver unit storage section 153 in an upright position and stored in a state where they are lined up at intervals in the thickness direction (left-right direction) of the component units 51.

[0072] 7, the receiver unit storage section 153 has a storage shelf 30. The storage shelf 30 is configured similarly to each storage shelf 20 of the emergency broadcast unit storage section 152.

[0073] The storage shelf 30 is a rectangular box having an opening 30a on the front side. The storage shelf 30 has an upper plate portion 30U, a lower plate portion 30D, a left plate portion, a right plate portion 30R, and a rear plate portion 30B. The storage shelf 30 also has multiple pairs of guide portions 31, a main board 32, and multiple power connectors 33.

[0074] The front end surface 30b of the upper plate portion 30U is provided with a plurality of screw holes 30c into which fixing pieces 514b (described later) of each of the plurality of constituent units 51 are screwed. The front end surface 30d of the lower plate portion 30D is provided with a plurality of screw holes 30e into which fixing pieces 514b (described later) of each of the plurality of constituent units 51 are screwed.

[0075] The multiple pairs of guide parts 31 correspond one-to-one to the multiple constituent units 51 stored in the storage shelf 30, and guide the corresponding constituent units 51 from the opening 30a of the storage shelf 30 to the back of the storage shelf 30. The multiple guide parts 31 are arranged in the storage shelf 30 at locations where the corresponding constituent units 51 are stored.

[0076] More specifically, each pair of guide parts 31 has an upper guide part 31a and a lower guide part 31b. The upper guide part 31a is disposed on the lower surface of the upper plate part 30U, and the lower guide part 31b is disposed on the upper surface of the lower plate part 30D. The upper guide part 31a has an upper groove part extending from one end to the other end in the longitudinal direction (front-rear direction) of the upper guide part 31a. The lower guide part 31b has a lower groove part extending from one end to the other end in the longitudinal direction (front-rear direction) of the lower guide part 31b. The upper side part and the lower side part of the constituent unit 51 are slidably fitted into the upper groove part of the upper guide part 31a and the lower groove part of the lower guide part 31b, respectively, so that each pair of guide parts 31 guides the corresponding constituent unit 51 from the opening part 30a of the storage shelf 30 to the back of the storage shelf 30.

[0077] The lower guide portions 31b of the pairs of guide portions 31 are disposed at intervals from each other along the left-right direction (the direction in which the left and right plate portions 30R are aligned) on the upper surface of the lower plate portion 20D. The upper guide portions 31a of the pairs of guide portions 31 are disposed directly above the lower guide portions 31b that form a pair on the lower surface of the upper plate portion 20U.

[0078] The main board 32 is disposed on the front surface of the rear plate portion 30B of the storage shelf 30. The main board 32 is, for example, a rectangular plate. The main board 32 is disposed on the front surface of the rear plate portion 30B with the rear surface of the main board 32 overlapping the front surface of the rear plate portion 30B.

[0079] The multiple power connectors 33 correspond one-to-one to the multiple configuration units 51 stored in the storage shelf 30, and are connectors for connecting to power connection parts 513 (described later) of the corresponding configuration units 51. The multiple power connectors 33 supply power from the power supply unit 10 to the corresponding configuration units 51 stored in the storage shelf 30.

[0080] The multiple power connectors 33 are arranged at intervals from one another in the left-right direction (the direction in which the left plate portion and the right plate portion 30R are aligned) on the front surface of the main board 32. Each of the multiple power connectors 33 is arranged at a position on the front surface of the main board 32 corresponding to the storage location of the corresponding configuration unit 51. The connection surface of each of the multiple power connectors 33 faces forward.

[0081] 6, each of the multiple component units 51 is configured in the same manner as each component unit 61 of the emergency broadcast unit 6. The component unit 51 has a circuit board 511, a connection portion 512, a power connection portion 513, and a fixed portion 514. The connection portion 512, the power connection portion 513, and the fixed portion 514 correspond to the component unit 51 having these respective portions (connection portion 512, power connection portion 513, and fixed portion 514). The multiple component units 51 are in one-to-one correspondence with the multiple power connectors 33 of the storage shelf 30.

[0082] The circuit board 511 is a board on which various electronic components to be mounted in the corresponding structural unit 51 are mounted. Wiring for electrically connecting the various electronic components mounted on the circuit board 511 is provided on the circuit board 511 by pattern formation or the like. The circuit board 511 is, for example, in the form of a rectangular plate. The circuit board 511 has two main surfaces (a first main surface 511a and a second main surface 511b) on both sides in the thickness direction of the circuit board 511.

[0083] The connection portion 512 is a portion to which a plurality of wires are connected. The plurality of wires include wires from the corresponding component unit 51, wires from other component units 51, wires from the emergency broadcast unit 6, and wires from each of the plurality of sensors 2.

[0084] The connection part 512 is disposed on a portion (e.g., an end) 511s on one side (front side) of the first main surface 511a of the circuit board 511. The "one side" refers to the opening 30a side (i.e., opening 15a side) of the storage shelf 30 of the component unit 51 when the component unit 51 is stored in the storage shelf 30 (i.e., the receiver unit storage section 153). The connection surface 512g of the connection part 512 faces the one side. More specifically, the connection part 512 has a plurality of connection holes 512a to which the plurality of wirings are connected. The plurality of connection holes 512a are disposed, for example, lined up in the vertical direction on the connection surface 512g of the connection part 512.

[0085] The power connection part 513 is a part that is detachably connected to a corresponding power connector 33 in the storage shelf 30. The configuration unit 51 operates with power supplied from the power connection part 513. The power connection part 513 is disposed in a part (e.g., an end part) 511t on the opposite side to the one side on the first main surface 511a of the circuit board 511. The connection surface of the power connection part 513 faces the opposite side to the one side. In other words, the power connection part 513 is disposed in a part of the receiver unit 5 on the side in the insertion direction of the receiver unit 5 into the receiver unit storage part 153.

[0086] 6, the portion 511s is an end portion of the one side (front side) of the first main surface 511a of the circuit board 511. However, the portion 511s may be within a range from one side (front side) of the one side (front side) of the first main surface 511a to a position about one-third of the front-to-rear length of the first main surface 511a toward the opposite side (rear side). This range is assumed to be a range within which the hand of a worker can reach the connection portion 512 when wiring the connection portion 512 from the opening 15a side of the main body 15.

[0087] Fixing portion 514 is a portion for fixing component unit 51 to storage shelf 30 (i.e., receiver unit storage section 153). Fixing portion 514 is disposed on first main surface 511a of circuit board 511 at one side portion (e.g., end portion) 511s.

[0088] More specifically, the fixing portion 514 is, for example, in the shape of a rectangular plate. The fixing portion 514 has a fixing portion main body 514a and a pair of fixing pieces 514b.

[0089] The fixing part main body 514a is, for example, plate-shaped (for example, rectangular plate-shaped). The fixing part main body 514a is arranged, for example, by screwing, in the above-mentioned one side portion (for example, end portion) 511s of the first main surface 511a of the circuit board 511 in a state where it stands perpendicular to the first main surface 511a. The fixing part main body 514a has a notch 514c. The notch 514c is cut out in a concave shape from the end portion on the circuit board 511 side toward the opposite end portion in the fixing part main body 514a. The notch 514c is a portion where the connecting part 512 is arranged in a fitted state. The notch 514c is formed in a rectangular shape of the same shape and size as the connecting part 512.

[0090] The pair of fixing pieces 514b protrude in the vertical direction from both ends in the vertical direction of the fixing portion main body 514a. More specifically, the pair of fixing pieces 514b protrude in the vertical direction from both ends in the vertical direction (upper side and lower side) of the circuit board 511. Each fixing piece 514b is provided with an insertion hole 514d through which a screw is inserted.

[0091] Next, a procedure for storing the component unit 51 will be described with reference to FIGS.

[0092] The component unit 51 is inserted into the storage shelf 30 from the power connection portion 513 side with the circuit board 511 standing upright. More specifically, the component unit 51 is inserted into the storage shelf 30 from the opening 30a of the storage shelf 30 between a pair of corresponding guide portions 31 (upper guide portion 31a and lower guide portion 31b) in the storage shelf 30. At this time, the upper side portion of the circuit board 511 is fitted into the upper groove portion of the upper guide portion 31a and guided along the upper guide portion 31a. Also, the lower side portion of the circuit board 511 is fitted into the groove portion of the lower guide portion 31b and guided along the lower guide portion 31b. As a result, the component unit 51 is guided by the pair of guide portions 31 and inserted to the back of the storage shelf 30.

[0093] When the configuration unit 51 is inserted to the back of the storage shelf 30, the power connection portion 513 of the configuration unit 51 is connected to the power connector 33 of the storage shelf 30. Furthermore, the pair of fixing pieces 514b of the fixing portion 514 of the configuration unit 51 contact the front end surface 30b of the upper plate portion 30U and the front end surface 30d of the lower plate portion 30D of the storage shelf 30. Then, the screw N4 is inserted through the insertion hole 514d of the upper fixing piece 514b and screwed into the screw hole 30c of the front end surface 30b. Furthermore, the screw N5 is inserted through the insertion hole 514d of the lower fixing piece 514b and screwed into the screw hole 30e of the front end surface 30d. As a result, the pair of fixing pieces 514b of the configuration unit 51 are fixed to the front end surface 30b of the upper plate portion 30U and the front end surface 30d of the lower plate portion 30D of the storage shelf 30. In this manner, the constituent unit 51 is stored in the storage shelf 30.

[0094] (2.2.4) Power supply unit storage area 3, the power supply unit storage section 154 is a storage section that stores the power supply units 10 (the first power supply unit 11 and the second power supply unit 12). The power supply unit storage section 154 is located below the receiver unit storage section 153 inside the main body section 15. The power supply unit storage section 154 is configured by the lower part of the front surface of the rear wall 15B of the main body section 15, the lower part of the inner surface of the left wall 15L, and the lower part of the inner surface of the right wall 15R.

[0095] The first power supply unit 11 and the second power supply unit 12 are stored vertically side by side in the power supply unit storage section 154. In the example of Fig. 3, the first power supply unit 11 is disposed on the upper side, and the second power supply unit 12 is disposed on the lower side.

[0096] When stored in the power supply unit storage section 154, the first power supply unit 11 and the second power supply unit 12 are each fixed to the inner surface 154a of the power supply unit storage section 154 (i.e., the front surface of the rear wall 15B), for example, by being screwed in.

[0097] More specifically, as shown in FIG. 8, the first power supply unit 11 and the second power supply unit 12 each have a circuit section that performs the power supply circuit function and a housing 40 that houses the circuit section. The housing 40 has a housing main body 40a and a pair of fixing pieces 40b. The housing main body 40a is, for example, a rectangular parallelepiped box. The pair of fixing pieces 40b are fixed to the back surface 154a of the power supply unit storage section 154 by screwing. The pair of fixing pieces 40b are provided on the housing main body 40a so as to protrude outward in the left-right direction from the rear edges of the left and right side surfaces of the housing main body 40a. Each fixing piece 40b is provided with an insertion hole 40c through which a screw N6 for screwing is inserted. On the other hand, the back surface 154a of the power supply unit storage section 154 is provided with a screw hole E6 through which the screw N6 is screwed.

[0098] The first power supply unit 11 is disposed in the power supply unit storage section 154 so that the rear surface of the housing 40 of the first power supply unit 11 contacts the rear surface 154a of the power supply unit storage section 154. In this disposed state, the screw N6 is inserted from the front side through the insertion hole 40c of the fixing piece 40b and screwed into the screw hole E6 in the rear surface 154a of the power supply unit storage section 154. That is, the fixing piece 40b is fixed to the rear surface 154a of the power supply unit storage section 154 by the screw N6. As a result, the first power supply unit 11 is stored in the power supply unit storage section 154.

[0099] Similar to the first power supply unit 11, the fixing piece 40b of the second power supply unit 12 is fixed to the inner surface 154a of the power supply unit storage section 154 by the screw N6.

[0100] (2.2.5) Emergency telephone unit storage area 3, the emergency telephone unit storage section 155 is a storage section that stores the emergency telephone unit 93 of the emergency telephone device 9. In this embodiment, the emergency telephone unit 93 is shared by at least one of the first power supply unit 11 and the second power supply unit 12 (the first power supply unit 11 in the example of FIG. 1). Therefore, the emergency telephone unit storage section 155 is also shared by the power supply unit storage section 154.

[0101] In the first embodiment, the first power supply unit 11 and the second power supply unit 12 are included in the power supply unit 10, but the first power supply unit 11 and the second power supply unit 12 may be independent of each other. In this case, the first power supply unit 11 and the second power supply unit 12 that are independent of each other may be stored in power supply unit storage sections that are independent of each other.

[0102] When stored in the emergency telephone unit storage section 155, the emergency telephone unit 93 is fixed to the inner surface 155a of the emergency telephone unit storage section 155 (i.e., the inner surface 154a of the emergency telephone unit storage section 155) by, for example, screwing.

[0103] More specifically, as shown in FIG. 8, the emergency telephone unit 93 has a circuit section that performs an emergency telephone function and a housing 50 that houses the circuit section. The housing 50 has a housing main body 50a and a pair of fixed pieces 50b. The housing main body 50a is a portion that houses the circuit section and is, for example, a rectangular parallelepiped box. The pair of fixed pieces 50b are portions that are fixed to the back surface 155a (i.e., the front surface of the rear wall 15B) of the emergency telephone unit storage section 155 by screwing. The pair of fixed pieces 50b are provided on the housing main body 50a so as to protrude outward in the left-right direction from the rear edges of the left and right side surfaces of the housing main body 50a. Each fixed piece 50b is provided with an insertion hole 50c through which a screw N7 for screwing is inserted. On the other hand, the back surface 155a of the emergency telephone unit storage section 155 is provided with a screw hole E7 through which the screw N7 is screwed.

[0104] The housing body 50a and the pair of fixing pieces 50b may be integrally formed. For example, the housing body 50a and the pair of fixing pieces 50b may be formed by bending a metal plate.

[0105] In this embodiment, the housing 50 of the emergency telephone unit 93 is also used as the housing 40 of the first power supply unit 11. The screw N7 for screwing the emergency telephone unit 93 is also used as the screw N6 for screwing the first power supply unit 11. The screw hole E7 of the emergency telephone unit storage section 155 is also used as the screw hole E6 for screwing the first power supply unit 11 in the power supply unit storage section 154.

[0106] The emergency telephone unit 93 is disposed in the emergency telephone unit storage section 155 so that the rear surface of the housing 50 of the emergency telephone unit 93 contacts the rear surface 155a of the emergency telephone unit storage section 155 (i.e., the front surface of the rear wall 15B). In this disposed state, the screw N7 is inserted from the front side through the insertion hole 50c of the fixing piece 50b and screwed into the screw hole E7 in the rear surface 155a of the emergency telephone unit storage section 155. In other words, the fixing piece 50b is fixed to the rear surface 155a of the emergency telephone unit storage section 155 by the screw N7. As a result, the emergency telephone unit 93 is stored in the emergency telephone unit storage section 155.

[0107] (2.2.6) Lid Configuration 2 and 3, the lid part 16 is a member that manually opens and closes the opening 15a (see FIG. 3) of the main body part 15. The lid part 16 is, for example, in the shape of a rectangular plate. One side (for example, the left side) of the lid part 16 is connected by a hinge to the edge part of the one side of the opening 15a of the main body part 15. The lid part 16 opens and closes the opening 15a of the main body part 15 by rotating about the hinge.

[0108] As shown in FIG. 9, the display unit 3, the operation unit 4, the telephone master unit 91 of the emergency telephone device 9, and the emergency broadcast microphone 13 are arranged on the outer main surface 16a of the lid portion 16. The display unit 3 is arranged, for example, in the center in the up-down direction on the outer main surface 16a of the lid portion 16. The operation unit 4 is arranged around (for example, on the upper side) the display unit 3. The operation unit 4 includes a plurality of operation buttons 4a. The telephone master unit 91 is arranged below the display unit 3. More specifically, the outer main surface 16a of the lid portion 16 is provided with a recess 16b corresponding to the telephone master unit 91. The telephone master unit 91 is arranged inside the recess 16b. The microphone 13 is arranged below the display unit 3. More specifically, the outer main surface 16a of the lid portion 16 is provided with a recess 16c corresponding to the microphone 13. The microphone 13 is arranged inside the recess 16c.

[0109] (2.2.7) Explanation of wiring work for emergency broadcast system 3, in the emergency broadcast system 1, when each component unit 61 of the emergency broadcast unit 6 is stored in the emergency broadcast unit storage section 152, the connection section 612 of each component unit 61 is arranged facing the opening 15a of the main body section 15 of the housing 14. Also, when each component unit 51 of the receiver unit 5 is stored in the receiver unit storage section 153, the connection section 512 of each component unit 51 is arranged facing the opening 15a of the main body section 15. Therefore, an operator can perform wiring connections between each component unit 61, wiring connections between each component unit 51, and wiring connections between the component units 61, 51, etc. from the front side of the opening 15a of the main body section 15.

[0110] As a comparative example, consider a case in which, when the emergency broadcast unit 6 is stored in the emergency broadcast unit storage section 152, each connection part 612 of the emergency broadcast unit 6 faces the rear surface 152a of the emergency broadcast unit storage section 152, and, when the receiver unit 5 is stored in the receiver unit storage section 153, each connection part 512 of the receiver unit 5 faces the rear surface 153a of the receiver unit storage section 153.

[0111] In the above comparative example, when the emergency broadcast unit 6 is stored in the emergency broadcast unit storage section 152, each connection part 612 of the emergency broadcast unit 6 faces the back surface 152a of the emergency broadcast unit storage section 152, and when the receiver unit 5 is stored in the receiver unit storage section 153, each connection part 512 of the receiver unit 5 faces the back surface 153a of the receiver unit storage section 153. For this reason, when performing the wiring connection work of each of the emergency broadcast unit 6 and the receiver unit 5, the worker goes around to the rear side of the main body part 15 and removes a part of the rear wall 15B of the main body part 15 to secure a window for wiring work. Then, the worker performs the wiring connection work of each of the emergency broadcast unit 6 and the receiver unit 5 from the secured window part. For this reason, the workability of the wiring work is poor because it is necessary to go around to the rear side of the main body part 15, it is necessary to remove a part of the rear wall 15B to secure a window for wiring work, and it is necessary to perform the wiring connection work from a relatively small window part for wiring connection. In contrast, in the emergency broadcast system 1 of this embodiment, the wiring connection work is performed through the opening 15a of the main body 15, so that the workability of the wiring connection work can be improved compared to the comparative example.

[0112] (3) Effects The emergency broadcast system 1 according to this embodiment includes a housing 14 and an emergency broadcast unit 6. The emergency broadcast unit 6 is stored in the housing 14 and has an emergency broadcast function. The housing 14 includes a main body 15 and a lid 16. The main body 15 includes an opening 15a and an emergency broadcast unit storage section 152. The emergency broadcast unit storage section 152 stores the emergency broadcast unit 6 introduced through the opening 15a. The lid 16 opens and closes the opening 15a of the main body 15. The emergency broadcast unit 6 includes a connection section 612 to which wiring is connected. The connection section 612 is disposed on the side of the opening 15a in the emergency broadcast unit 6 when the emergency broadcast unit 6 is stored in the emergency broadcast unit storage section 152.

[0113] According to this configuration, the connection portion 612 of the emergency broadcast unit 6 is disposed on the side of the opening 15a in the emergency broadcast unit 6 (more specifically, the circuit board 611) when the emergency broadcast unit 6 is stored in the emergency broadcast unit storage portion 152. Therefore, the wiring connection work of the emergency broadcast unit 6 stored in the emergency broadcast unit storage portion 152 can be performed from the opening 15a side of the main body portion 15 of the housing 14.
