Each part of the wireless receiver 1 has the above-described configuration, and is applied to the building surface in the following order.

The printed circuit boards 25, 26, the terminal device 30, and the operation knob 31 are preliminarily mounted inside the receiver body 20, and the constructor locks the left and right locking claws 34 of the receiver body 20 to the holes 63 of the mounting frame 60. The receiver body 20 is mounted to the mounting frame 60. The constructor pulls out the electric wire from a mounting hole (not shown) for mounting the appliance on the building surface, peels off the coating layer at the front end, and inserts the electric wire from the electric wire insertion opening into the inside of the receiver main body 20 and the terminal device 30 Electrical connection. If the wire connection to the wireless receiver 1 is completed, the constructor presses the remaining length of the wire into the mounting hole, and then, in a suitable method (for example, a method of fixing the screw to the buried case, Or the method of fixing to the wall material using a clamping clip) fixing the mounting frame 60 to the building surface. Further, as shown in FIG. 1(a), in a state in which the receiver main body 20 is attached to the mounting frame 60, the front body 22 constituting the front portion of the receiver main body 20 is exposed forward from the window hole 60a of the mounting frame 60.

When the receiver main body 20 is fixed to the building surface by using the mounting frame 60, the constructor performs an operation of registering the identification information of the transmitter 2 used in combination with the wireless receiver 1. When the operator presses the operation button 36a of the registration switch 15a for a predetermined period of time while the power is supplied to the wireless receiver 1, the control unit 10 switches to the registration mode of the registration identification information based on the operation input from the registration switch 15a. When switching to the registration mode, the control unit 10 causes the display unit 13 to blink to notify the constructor that the registration mode has been switched. When the constructor confirms that the switching mode has been switched from the blinking state of the display unit 13, the transmitter 2 that is used in combination with the wireless receiver 1 transmits the identification information. When the receiving unit 11 receives the identification information transmitted from the transmitter 2 and outputs it to the control unit 10, the control unit 10 stores the identification information in a memory (not shown), and then causes the display unit 13 to light up, for example. Time to inform the constructor that the identification information has been registered. Then, when the constructor presses the operation button 36a for a predetermined period of time or after a certain period of time has elapsed after switching to the registration mode, the control unit 10 ends the registration mode and shifts to the normal control mode. Further, when the identification information is not registered, the control unit 10 may cause the display unit 13 to light or blink in a state different from the normal control mode or the registration mode, thereby causing the constructor to register the identification information. Further, when the constructor presses the clear switch 15b for a predetermined period of time, the control unit 10 clears the identification information stored in the memory based on the operation input from the clear switch 15b. At this time, the control unit 10 lights or blinks the display unit 13 in a state different from the normal control mode or the registration mode, and notifies the constructor that the identification information is not registered.

When the job of registering the identification information of the transmitter 2 is completed, the constructor mounts the bottom cover 23 on the front side of the receiver body 20. When the constructor causes the back surface of the bottom cover 23 to face the front surface of the receiver body 20, and the bottom cover 23 is brought close to the front surface of the receiver body 20 in a state where the position of the locking piece 40 and the groove 39 are substantially coincident, the protrusion portion The end of the 38 abuts against the guide surface 41a of the guide rib 41. When the constructor brings the bottom cover 23 closer to the receiver body 20 side, the bottom cover 23 is guided to the protruding portion 38 by the guide surface 41a and the end portion of the protruding portion 38 is fitted between the two guide ribs 41. Position (refer to Figure 4). In this manner, since the bottom cover 23 is positioned in the receiver main body 20 in the left-right direction, the claws 40a of the locking piece 40 do not climb up to the peripheral edge portion of the groove 39, but are surely locked in the groove 39. Moreover, the claw 40a of the locking piece 40 is hooked in the groove 39, so as shown in Fig. 1(b) and As shown in Fig. 6, the bottom cover 23 is mounted to the receiver body 20. In the state in which the bottom cover 23 is attached to the receiver main body 20, the operation buttons 36a and 36b of the registration switch 15a and the clearing switch 15b are covered by the bottom 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 portion 23c, the operation knob 31 of the first switch 14 is in an operable state.

Thereafter, the constructor causes the back surface of the top cover 24 to face the front surface of the bottom cover 23, aligns the position of the locking piece 43 and the locking hole 42, and brings the top cover 24 close to the bottom cover 23 side. At this time, the locking piece 43 is inserted into the corresponding locking hole 42, and the claw 43a of the locking piece 43 is locked with the opening edge of the locking hole 42, so that the top cover 24 is attached to the bottom cover 23 (refer to FIG. 1 (c) )). In a state where the top cover 24 is attached to the bottom cover 23, the operation knob 31 is covered by the top cover 24, so that the operation knob 31 of the first switch 14 is in an inoperable state.

Finally, the constructor screwes the plate frame 71 to the front side of the mounting frame 60, and mounts the decorative frame 72 on the front side of the plate frame 71, thereby completing the construction of the wireless receiver 1 (refer to FIG. 10(a)).

Next, an operation of the wireless receiver 1 to control the lighting/extinction of the lighting load 4 will be described. The facility manager of the building provided with the lighting load 4 operates the first switch 14 so that the control mode of the lighting load 4 can be selected. When the facility manager operates the first switch 14 and selects the extinction mode, the control unit 10 always turns off the opening and closing unit 12 regardless of the wireless signal received by the receiving unit 11, and causes the lighting load 4 to be always turned off. When the facility manager operates the first switch 14 and selects the lighting mode, the control unit 10 always turns on the opening and closing unit 12 regardless of the wireless signal received by the receiving unit 11, so that the lighting load 4 is always turned on. bright. Further, when the facility manager operates the first switch 14 and selects the automatic mode, the control unit 10 automatically controls the lighting state of the lighting load 4 based on the wireless signal received by the receiving unit 11. When the receiving 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, and reads the control command included in the wireless signal if the identification information matches. Then, the control unit 10 turns on or off the opening and closing unit 12 based on the read control command (lighting command or extinguishing command), thereby automatically turning on or off the lighting load 4.

Here, in a state where the wireless receiver 1 is applied to the building surface as described above, as shown in FIG. 10(a), the operation knob 31 or the second switch 14 of the first switch 14 is provided by the bottom cover 23 and the top cover 24. The operation buttons 36a, 36b of the switch 15 are hidden. Therefore, for the use of the wireless receiver 1 The general user of the building (for example, a customer who temporarily uses a large-scale shop or a public facility, etc.) does not know the existence of the operation knob 31 and the operation buttons 36a, 36b. Therefore, the possibility that the general user operates the operation knob 31 or the operation buttons 36a, 36b or erroneously contacts the operation knob 31 or the operation buttons 36a, 36b is reduced, and the control mode or change of changing the illumination load 4 by the general user is reduced. The possibility of setting wireless communication.

On the other hand, a case will be described in which the facility manager that manages the facility in which the wireless receiver 1 is installed switches the control mode in which the wireless receiver 1 controls the lighting load 4 in the use state of the wireless receiver 1. As shown in FIG. 10(a), the entire top cover 24 is disposed on the front side of the front surface of the decorative panel 70, so that the fingers can be hooked in the grooves 45 located on the left and right side edges of the top cover 24. Therefore, when the facility manager wants to change the control mode, the facility manager releases the nail by hooking it in the groove 45 provided on the left edge or the right edge of the top cover 24 and pulling it toward the front side. The locked state between the claw 43a of the locking piece 43 on the side and the locking hole 42. When the locked 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 toward the front side and the locking piece on the opposite side. 43 is pulled out of the locking hole 42, thereby detaching the top cover 24 from the bottom cover 23. At this time, since the operation knob 31 of the first switch 14 is exposed forward from the opening 23c of the bottom cover 23, the facility manager can operate the operation knob 31 to switch the control mode of the illumination load 4. When the switching operation of the control mode is completed, the facility manager attaches the top cover 24 to the front surface of the bottom cover 23, and the state in which the operation knob 31 is covered by the top cover 24 is obtained.

As described above, the wireless receiver 1 of the present embodiment includes the receiving unit 11, the opening and closing unit 12, the control unit 10, the receiver body 20, the first and second switches 14, 15 and the first cover (constructed by the bottom cover 23) ), a second cover (consisting of the top cover 24). The receiving unit 11 receives a wireless signal. The opening and closing unit 12 opens and closes a power supply path from a power source to a load (in the present embodiment, the lighting load 4). The control unit 10 controls the opening and closing state of the opening and closing unit 12 based on the wireless signal received by the receiving unit 11, thereby controlling the operation of the load. The receiver body 20 houses the receiving unit 11 , the opening and closing unit 12 , and the control unit 10 . The first switch 14 and the second switch 15 are respectively provided with operation portions on the front surface of the receiver body 20.

On the other hand, if the second cover is removed, only the first switch can be operated, and if both the first cover and the second cover are removed, both the first switch and the second switch can be operated. Therefore, according to the detaching state of the first cover and the second cover, the operable range can be switched among the plurality of switches (consisting of the first switch and the second switch).

Further, the receiver body 20 is attached to the building material using a mounting frame 60 for embedding the wiring device, and the front surface of the receiver body 20 is exposed from the center hole 70a, and a decorative panel is attached to the front side of the mounting frame 60. In this state, the removal of the first cover is restricted by the decorative panel 70 disposed around the first cover (the bottom cover 23). Here, in the present embodiment, the gap between the inner surface of the hole 70a and the side portion 23b of the bottom cover 23 is formed as a narrow gap into which the human finger cannot enter, so that the front surface of the bottom cover 23 and the decorative panel 70 are formed. The front surface is roughly on the same side.

Therefore, in a state where the decorative panel 70 is attached to the mounting frame 60, the finger cannot be hooked on the side portion 23b of the bottom cover 23, and the bottom cover 23 cannot be removed, so the second switch 15 cannot be attached. Take action. Therefore, the constructor who performs the construction work of the wireless receiver 1 can operate the second switch 15, but after the construction of the wireless receiver 1, the facility manager using the wireless receiver 1 cannot operate the second switch 15. .

Further, in the embodiment of the present invention, the gap between the inner surface of the hole 70a and the side portion 23b of the bottom cover 23 is formed so that the finger cannot enter as narrow as the entry, and the front surface of the bottom cover 23 is set to the decorative panel 70. The front surface is substantially on the same surface, thereby restricting the removal of the bottom cover 23, but the method of restricting the removal is not limited to the above method. For example, the removal of the bottom cover 23 can be restricted by locking the decorative panel 70 and the bottom cover 23. Further, since the top cover 24 as the second cover is located on the front side more than the front surface of the decorative panel 70, the nail can be hooked on the groove 45 of the top cover 24 even in a state in which the decorative panel 70 is mounted on the mounting frame 60. In this case, the top cover 24 can be attached and detached.

Thus, when the user removes the top cover 24 from the bottom cover 23, the nail is hooked in the groove 45 on the left or right side of the top cover 24, and is pulled toward the front side, thereby releasing the one side (left side or Right) The locked state between the claw 43a of the locking piece 43 and the locking hole 42. At this time, the hooking direction of the claw 40a of the bottom cover 23 and the groove 39 are substantially perpendicular to the hooking direction in which the claw 43a is hooked to the locking hole 42, so that when the top cover 24 is detached from the bottom cover 23, the bottom cover 23 is not easy to be separated. Further, when the user removes the bottom cover 23 from the receiver main body 20, the claw of the locking piece 40 located on one side (upper or lower side) is released by pulling the upper or lower portion of the bottom cover 23 toward the front side. The locked state between 40a and slot 39. Therefore, since the hooking direction of the claw 40a of the bottom cover 23 and the groove 39 are substantially perpendicular to the hooking direction in which the claw 43a is hooked to the locking hole 42, the bottom cover 23 is not easily detached when the top cover 24 is detached. .

Further, in the present embodiment, as shown in FIG. 4, the gap D1 between the end surface of the outer side of the locking piece 40 (the side 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 is applied to the bottom cover 23 to pull the right end or the left end of the bottom cover 23 forward, since the outer end surface of the locking piece 40 abuts against the inner surface of the groove 39, the right end of the bottom cover 23 or The left end is not easy to move forward. Thus, even if a force is applied to the bottom cover 23 in a direction (left-right direction) orthogonal to the direction in which the claws 40a of the locking piece 40 and the groove 39 are locked (vertical direction), the locking between the claw 40a and the groove 39 is performed. The state is also not easily released, and the bottom cover 23 is not easily detached from the receiver body 20.

In this way, the receiver body 20 is provided with a restricting portion (an end surface of the groove 39) which is separated from the first engaged portion with respect to the first locking claw (the claw 40a of the locking piece 40) The groove 39) is hooked in a direction orthogonal to the hooking direction, and abuts against the first locking claw (the claw 40a of the locking piece 40), thereby restricting the first locking claw in a direction orthogonal to the hooking direction. The range of movement.

Thereby, even if a force is applied to the first cover in a direction orthogonal to the hooking direction of the first locking claw (the claw 40a of the locking piece 40) and the first engaged portion (the groove 39), Also, the locked state between the first locking claw and the first engaged portion is not easily released, and the first cover is not easily detached from the receiver body 20.
