  Each part of the wireless receiver 1 has the above structure, and is constructed on the construction surface in the following procedure.

  Printed wiring boards 25, 26, a terminal device 30, and an operation knob 31 are preinstalled in the receiver main body 20, and the contractor attaches the left and right engaging claws 34 of the receiver main body 20 to the mounting frame 60. The receiver main body 20 is attached to the attachment frame 60 by being locked in the hole 63. The contractor pulls out the electric wire from a mounting hole (not shown) for mounting the appliance that opens on the construction surface, peels off the coating on the tip, and inserts the electric wire into the receiver main body 20 from the electric wire insertion port. Electrically connected to device 30. When the wire connection to the wireless receiver 1 is completed, the contractor pushes the extra length of the wire into the mounting hole, and then attaches the mounting frame 60 to an appropriate method (for example, a method of fixing the mounting frame 60 with a screw, It is fixed to the construction surface by using the method of fixing to the wall material. 1A, when the receiver main body 20 is attached to the attachment frame 60, the front body 22 constituting the front portion of the receiver main body 20 moves forward from the window hole 60a of the attachment frame 60. Exposed.

  When the receiver main body 20 is fixed to the construction surface using the mounting frame 60, the contractor performs an operation of registering identification information of the transmitter 2 used in combination with the wireless receiver 1. When the contractor presses the operation button 36a of the registration switch 15a for a predetermined time while the power is supplied to the wireless receiver 1, the control unit 10 displays the identification information according to the operation input from the registration switch 15a. Switch to the registration mode to register. When the control unit 10 is switched to the registration mode, the control unit 10 notifies the contractor that the display mode is switched to the registration mode by blinking the display unit 13. When it is confirmed that the contractor has switched from the blinking state of the display unit 13 to the registration mode, the contractor causes the transmitter 2 used in combination with the wireless receiver 1 to transmit identification information. When the reception unit 11 receives the identification information transmitted from the transmitter 2 and outputs the identification information to the control unit 10, the control unit 10 stores the identification information in a memory (not shown) and then displays the display unit 13 for example. The construction company is informed that the identification information has been registered by lighting for a period of time. Thereafter, the control unit 10 ends the registration mode and shifts to the normal control mode when the contractor presses the operation button 36a for a predetermined time or when a certain period of time has elapsed since switching to the registration mode. When the identification information is not registered, the control unit 10 prompts the contractor to register the identification information by lighting or blinking the display unit 13 in a state different from the normal control mode or registration mode. Also good. When the contractor presses the erasure switch 15b for a predetermined time, the control unit 10 erases the identification information stored in the memory according to the operation input from the erasure switch 15b. At this time, the control unit 10 notifies the contractor that the identification information is not registered by lighting or blinking the display unit 13 in a state different from the normal control mode or the registration mode.

  When the operation for registering the identification information of the transmitter 2 is completed, the contractor attaches the base cover 23 to the front side of the receiver body 20. When the contractor points the back surface of the base cover 23 toward the front surface of the receiver body 20 and brings the base cover 23 close to the front surface of the receiver body 20 in a state where the positions of the locking pieces 40 and the grooves 39 are substantially matched, the protrusion The end of the portion 38 abuts on the guide surface 41 a of the guide rib 41. When the contractor brings the base cover 23 closer to the receiver body 20, the guide surface 41 a comes into contact with the end of the protrusion 38, so that the protrusion 38 fits between the two guide ribs 41. The base cover 23 is guided (see FIG. 4). Thus, since the base cover 23 is positioned on the receiver body 20 in the left-right direction, the claw 40a of the locking piece 40 is securely locked in the groove 39 without climbing on the peripheral edge of the groove 39. Then, when the claw 40 a of the locking piece 40 is caught in the groove 39, the base cover 23 is attached to the receiver body 20 as shown in FIGS. When the base cover 23 is attached to the receiver body 20, the operation buttons 36a and 36b of the registration switch 15a and the erasure switch 15b are covered with the base cover 23, so that the operation buttons 36a and 36b cannot be operated. . Further, since the operation knob 31 of the first switch 14 is exposed from the opening 23c, the operation knob 31 of the first switch 14 is operable.

  Thereafter, the contractor makes the back surface of the top cover 24 face the front surface of the base cover 23, aligns the positions of the locking pieces 43 and the locking holes 42, and brings the top cover 24 closer to the base cover 23 side. At this time, the locking piece 43 is inserted into the corresponding locking hole 42, and the claw 43 a of the locking piece 43 is locked with the opening edge of the locking hole 42, whereby the top cover 24 is attached to the base cover 23. (See FIG. 1 (c)). When the top cover 24 is attached to the base cover 23, the operation knob 31 is covered with the top cover 24, so that the operation knob 31 of the first switch 14 becomes inoperable.

  Finally, the installer completes the installation of the wireless receiver 1 by fixing the plate frame 71 with screws to the front side of the mounting frame 60 and attaching the decorative frame 72 to the front side of the plate frame 71 (FIG. 10A). reference).

  Next, an operation in which the wireless receiver 1 controls lighting / extinguishing of the illumination load 4 will be described. The facility manager of the building where the lighting load 4 is installed can select the control mode of the lighting load 4 by operating the first switch 14. When the facility manager operates the first switch 14 and selects the extinguishing mode, the control unit 10 always turns off the opening / closing unit 12 regardless of the wireless signal received by the receiving unit 11, so that the lighting load 4 is always turned on. Turn off the light. When the facility manager operates the first switch 14 to select the lighting mode, the control unit 10 always turns on the opening / closing unit 12 regardless of the wireless signal received by the receiving unit 11, and the lighting load 4 is always set. Light up. When the facility manager operates the first switch 14 to select the automatic mode, the controller 10 automatically controls the lighting state of the lighting load 4 according to the wireless signal received by the receiver 11. When the reception unit 11 receives the wireless signal, the control unit 10 determines whether or not the identification information included in the wireless signal matches the identification information registered in the memory. If the identification information matches, the control unit 10 includes the wireless signal. Capture control instructions. Then, the control unit 10 automatically turns on or off the lighting load 4 by turning on and off the opening / closing unit 12 in accordance with the taken control command (lighting command or light-off command).

  By the way, in the state in which the wireless receiver 1 is constructed on the construction surface as described above, the operation knob 31 of the first switch 14 and the first switch 14 by the base cover 23 and the top cover 24 as shown in FIG. The operation buttons 36a and 36b of the two switch 15 are hidden. Therefore, general users who use the building where the wireless receiver 1 is installed (for example, customers who temporarily use large-scale stores and public facilities) cannot know the presence of the operation knob 31 and the operation buttons 36a and 36b. . Therefore, the possibility that a general user operates the operation knob 31 and the operation buttons 36a and 36b or touches the operation knob 31 and the operation buttons 36a and 36b by mistake decreases, and the control mode of the lighting load 4 is changed by the general user. Or the possibility of changing wireless communication settings is reduced.

  On the other hand, the case where the facility manager who manages the facility where the wireless receiver 1 is installed in the use state of the wireless receiver 1 switches the control mode of the lighting load 4 by the wireless receiver 1 will be described. As shown in FIG. 10A, the entire top cover 24 is disposed in front of the front surface of the decorative plate 70, so that a finger can be caught in the grooves 45 on the left and right side edges of the top cover 24. It is like that. Therefore, when the facility manager wants to change the control mode, the facility manager can hook the nail into the groove 45 provided on the left side edge or the right side edge of the top cover 24 and pull it toward the front side, thereby The locking state between the claw 43a of the locking piece 43 and the locking hole 42 is released. When the locking state between the claw 43a of the locking piece 43 on one side and the locking hole 42 is released, the facility manager pulls the opposite side of the top cover 24 to the near side, and the locking piece on the opposite side The top cover 24 is removed from the base cover 23 by bringing 43 out of the locking hole 42. At this time, since the operation knob 31 of the first switch 14 is exposed forward from the opening 23c of the base cover 23, the facility manager can switch the control mode of the lighting load 4 by operating the operation knob 31. it can. When the control mode switching operation ends, the facility manager attaches the top cover 24 to the front surface of the base cover 23 and covers the operation knob 31 with the top cover 24.

As described above, the wireless receiver 1 of the present embodiment includes the receiving unit 11, the opening / closing unit 12, the control unit 10, the receiver body 20, the first and second switches 14 and 15, and the first A cover (comprising the base cover 23) and a second cover (comprising the top cover 24) are provided. The receiving unit 11 receives a wireless signal. The opening / closing unit 12 opens and closes a power feeding path from the power source to the load (in this embodiment, the illumination load 4). The control unit 10 controls the operation of the load by controlling the open / close state of the open / close unit 12 according to the wireless signal received by the receiving unit 11. The receiver body 20 houses the receiving unit 11, the opening / closing unit 12, and the control unit 10. As for the 1st switch 14 and the 2nd switch 15, the operation part is arrange | positioned at the front surface of the receiver main body 20, respectively.

The top cover 24 as the second cover is attached to the front side of the first cover and covers the operation portion of the first switch 14 exposed from the opening 23c.

  According to the present invention, both the first switch and the second switch cannot be operated when both the first cover and the second cover are attached to the receiver body. On the other hand, when the second cover is removed, only the first switch can be operated, and when both the first cover and the second cover are removed, both the first switch and the second switch can be operated. Therefore, the operable range can be switched with a plurality of switches (consisting of the first switch and the second switch) according to the attachment / detachment state of the first cover and the second cover.

  The receiver body 20 is attached to the construction material using the mounting frame 60 for the embedded wiring apparatus, and the decorative plate is placed on the front side of the mounting frame 60 so that the front surface of the receiver body 20 is exposed from the central hole 70a. Is attached. In this state, removal of the first cover is restricted by the decorative plate 70 disposed around the first cover (base cover 23). Here, in the present embodiment, the gap between the inner surface of the hole 70a and the side portion 23b of the base cover 23 is a narrow gap that prevents human fingers from entering, and the front surface of the base cover 23 is the front surface of the decorative plate 70. It is almost the same.

  Thereby, in a state where the decorative plate 70 is attached to the attachment frame 60, it is impossible to put a finger on the side portion 23 b of the base cover 23 and the base cover 23 cannot be removed. You can not do it. Accordingly, the second switch 15 can be operated by a contractor who performs the construction work of the wireless receiver 1, but the facility manager who operates the wireless receiver 10 after the construction of the wireless receiver 10 operates the second switch 15. The operation cannot be performed.

  Note that the gap between the inner surface of the hole 70a and the side portion 23b of the base cover 23 is narrowed so that fingers do not enter, and the front surface of the base cover 23 is substantially flush with the front surface of the decorative plate 70. However, the method for regulating the removal is not limited to the above method. For example, the removal of the base cover 23 may be regulated by locking the decorative plate 70 and the base cover 23. Further, since the top cover 24 as the second cover is located in front of the front surface of the decorative plate 70, the nail is caught in the groove 45 of the top cover 24 even when the decorative plate 70 is attached to the attachment frame 60. The top cover 24 can be attached and detached.

  As described above, the claw 43a of the locking piece 43 provided in the top cover 24 and the opening edge of the locking hole 42 provided in the base cover 23 are locked in the left-right direction. Further, the claw 40a of the locking piece 40 provided on the base cover 23 and the groove 39 of the receiver body 20 are locked in the vertical direction. That is, the hooking direction in which the first locking claw (claw 40a) is hooked on the first locked portion (groove 39), and the second locking claw (claw 43a) is the second locked portion (locking hole 42). The hooking direction to be hooked is perpendicular to each other.

  As a result, when the user removes the top cover 24 from the base cover 23, the nail is hooked on the groove 45 on the left side or the right side of the top cover 24 and pulled toward the front side. The locked state between the claw 43a of the stopper piece 43 and the locking hole 42 is released. At this time, the hooking direction in which the claw 40a of the base cover 23 is caught in the groove 39 is substantially orthogonal to the hooking direction in which the claw 43a is hooked with the locking hole 42. Therefore, when the top cover 24 is removed from the base cover 23, the base cover 23 becomes difficult to come off together. Further, when the user removes the base cover 23 from the receiver body 20, the upper or lower portion of the base cover 23 is pulled toward the front side, so that the claw 40 a and the groove of the locking piece 40 on one side (upper side or lower side) are removed. The locked state with 39 is released. Therefore, the hooking direction in which the claw 40a of the base cover 23 is caught in the groove 39 is substantially perpendicular to the hooking direction in which the claw 43a is hooked with the locking hole 42. Therefore, when removing the base cover 23, only the top cover 24 is difficult to come off. Become.

  In the present embodiment, as shown in FIG. 4, the gap D <b> 1 between the outer end surface of the locking piece 40 (opposite to the center position in the left-right direction) and the inner surface of the groove 39 is set to be substantially zero. Therefore, even if a force that pulls the right end or the left end of the base cover 23 forward is applied to the base cover 23, the outer end surface of the locking piece 40 abuts on the inner surface of the groove 39. It becomes difficult for the right end or the left end to move forward. Therefore, even when a force in the direction (left-right direction) perpendicular to the direction (vertical direction) in which the claw 40 a of the locking piece 40 is locked to the groove 39 is applied to the base cover 23, the locking of the claw 40 a and the groove 39 is performed. It becomes difficult for the state to come off and the base cover 23 becomes hard to come off from the receiver body 20.

  In this way, the first locking claw (the claw of the locking piece 40) from the direction perpendicular to the direction in which the first locking claw (the claw 40a of the locking piece 40) is hooked on the first locked portion (the groove 39). The receiver main body 20 is provided with a restricting portion (an end surface of the groove 39) for restricting the movement range of the first locking claw in a direction orthogonal to the hooking direction by contacting with 40a).

  As a result, even if a force in a direction perpendicular to the direction in which the first locking claw (claw 40a of the locking piece 40) is hooked on the first locked portion (groove 39) is applied to the first cover, The locking state between the locking claw and the first locked portion is difficult to come off, and the first cover is hard to come off from the receiver body 20.

  Further, in the present embodiment, in order to position the base cover 23 on the receiver body 20 in the left-right direction, guide ribs 41 are provided on the back surface of the base cover 23 so as to sandwich the protruding portion 38 of the receiver body 20 from both sides. ing. Therefore, when the base cover 23 is attached to the receiver main body 20, the end of the protrusion 38 abuts against the guide surface 41 a of the guide rib 41 so that the protrusion 38 fits between the two guide ribs 41. The base cover 23 is positioned with respect to the receiver body 10. Thus, since the first cover 22 is positioned on the receiver body 20 in the left-right direction, the claw 40a of the locking piece 40 does not run on the peripheral edge of the groove 39, and the claw 40a is caught in the groove 39, A base cover 23 is attached to the receiver body 20.

  In this way, one of the receiver main body 20 and the first cover (base cover 23) is slidably brought into contact with the projecting portion 28 provided on the other, so that the first locked portion (groove) is obtained. 39) is provided with a guide rib 41 for guiding the first locking claw (the claw 40a of the locking claw 40).

  Thereby, the position of a 1st to-be-latched part and a 1st latching | locking part can be match | combined, and a 1st latching claw can be reliably latched to a 1st to-be-latched part.

  In the present embodiment, the first switch 14 is a switch for switching the operation state of the load, and the second switch 15 is a switch for performing settings related to the reception operation of the reception unit 11.

  As a result, the second switch 15 used at the time of construction is hidden even when the second cover is removed, so that the second switch 15 is erroneously operated, and the settings related to the reception operation are changed unintentionally. The possibility of being reduced can be reduced. If the operating state of the load is to be changed, the operation part of the first switch is exposed from the opening of the first cover when the second cover is removed. It is possible to change the operation state. In the present embodiment, the first switch 14 is a switch for switching a load control mode, and the second switch 15 is a switch for setting identification information. However, the applications of the first switch 14 and the second switch 15 are described above. It is not limited to the use.
