In addition, arrows indicating the directions in the drawings are only shown for the purpose of explanation and do not have an entity.

(2) Details (2.1) Circuit Configuration The circuit configuration of the load control device 1 will be described with reference to FIG.

  The load control device 1 of the present embodiment is used, for example, to control turning on / off of a load L1 such as a lighting load.

  The main unit 2 includes a semiconductor switch 61, a main unit communication unit 62, an operation detection unit 63, a light emitting unit 64, a main control unit 65, and connection terminals 661 and 662. The main body 2 of the present embodiment includes a switch main body 4 (fixed part) fixed to a construction surface, and a handle 5 (movable part) attached to the switch main body 4 in an operable state according to a user operation ( See Figure 1). The semiconductor switch 61, the body side communication unit 62, the operation detection unit 63, the light emitting unit 64, the body side control unit 65, and the connection terminals 661 and 662 are accommodated in the switch body 4.

  For example, an alternating current power supply P1 such as a commercial power supply and a load L1 such as a lighting load are connected in series between the connection terminal 661 and the connection terminal 662.

  The semiconductor switch 61 includes two switch elements 611 and 612 made of, for example, an enhancement type n-channel MOSFET (Metal-Oxide-Semiconductor Field Effect Transistor). The gates of the switch elements 611 and 612 and the sources of the switch elements 611 and 612 are connected to each other, the drain of the switch element 611 is connected to the connection terminal 661, and the drain of the switch element 612 is connected to the connection terminal 662.

  The main body side communication unit 62 includes, for example, a light receiving element such as a photodiode that receives infrared light. The main body side communication unit 62 receives a control signal transmitted from the transmitter 3 as an optical signal (wireless signal) such as infrared light. That is, the main body side communication unit 62 of the present embodiment performs wireless communication with the transmitter 3 using light as a medium.

  The operation detection unit 63 includes, for example, a push button switch that performs a momentary operation. The switch body 4 is provided with a T-shaped movable bar 44 (see FIG. 1) at a position corresponding to the protrusion 52 (see FIG. 2) on the back surface of the handle 5. One end of the movable bar 44 is movable in the front-rear direction, and the push button switch provided in the operation detection unit 63 is disposed on the back side of the movable bar 44. When the handle 5 is pushed by the user, the projection 52 of the handle 5 pushes the movable bar 44 backward, and the push button switch is pushed on the back surface of the movable bar 44, so that the on / off of the push button switch changes. Thereby, the operation detection unit 63 can detect the operation of the handle 5 by the user, and outputs an operation signal according to the operation of the handle 5 to the main body side control unit 65.

  The light emitting unit 64 includes, for example, a light emitting diode emitting green light. A display unit 47 is disposed on the front of the switch body 4. The display unit 47 is formed of a translucent lens that outputs the light emitted from the light emitting unit 64 to the outside. The display unit 47 is in the switch main body 4 which is a fixed unit, and receives light from the light emitting unit 64 to emit light.

  The main body side control unit 65 is configured by, for example, a microcomputer having a processor and a memory. That is, the main body side control unit 65 is realized by a computer system having a processor and a memory. Then, when the processor executes an appropriate program, the computer system functions as the main body control unit 65. The program may be pre-recorded in a memory, or may be provided through a telecommunication line such as the Internet or in a non-transitory recording medium such as a memory card.

  The main body side control unit 65 controls the on / off of the semiconductor switch 61 according to the control signal received by the main body side communication unit 62 or the operation signal input from the operation detection unit 63, thereby the load L1. Turn on or off. The main-body control unit 65 can also control the on / off of the semiconductor switch 61 to perform phase control, thereby dimming the load L1.

  Further, the main body side control unit 65 controls the display content by the light emitting unit 64 (the display unit 47) by controlling turning on / off of the light emitting unit 64. For example, the main control unit 65 turns on the light emitting unit 64 when the load L1 is turned off, and turns off the light emitting unit 64 when the load L1 is turned on. Since the light emitting unit 64 is turned on when the load L1 is turned off, the user can grasp the position of the load control device 1 by the light of the light emitting unit 64 (display unit 47) even when the surroundings are dark. In addition, when performing the timer operation (operation of lighting the load L1 for a certain period of time), the main body side control unit 65 may blink the light emitting unit 64, and the user blinks the light emitting unit 64 (display unit 47). The operation state of the load control device 1 can be grasped based on

  The transmitter 3 includes a transmitter communication unit 71, an operation reception unit 72, and a transmitter control unit 73.

  The transmitter-side communication unit 71 communicates with at least the main-body-side communication unit 62 of the main unit 2, so that communication can be performed between the transmitter 3 and the main unit 2 using the transmitter 3. The transmitter-side communication unit 71 includes a light emitting element such as a light emitting diode that emits infrared light, for example. The transmitter communication unit 71 transmits a control signal to the main unit 2 as an optical signal (wireless signal) such as infrared light. That is, the transmitter communication unit 71 of the present embodiment performs wireless communication with the main unit 2 using light as a medium.

  The operation accepting unit 72 accepts an operation by the user. The operation accepting unit 72 includes a plurality of (for example, five) switches. On the rear surface of the transmitter 3, five operation units 331 are provided, corresponding to the five switches and for making the corresponding switches conductive. The five operation units 331 are, for example, a light on / off switching button, a light control bright button, a light control dark button, a light control light button, a timer light button, and the like. The dimming button is a button operated to brighten the brightness when the load L1 is lit. The light control dark button is a button operated to darken the brightness when the load L1 is on. The light control lighting button is a button operated to light the load L1 at a preset light control level. The timer lighting button is a button operated to perform a timer lighting operation of turning off the load L1 after turning on the load L1 for a predetermined time.

  The transmitter-side control unit 73 is configured of, for example, a microcomputer having a processor and a memory. That is, the transmitter-side control unit 73 is realized by a computer system having a processor and a memory. Then, when the processor executes an appropriate program, the computer system functions as the transmitter-side control unit 73. The program may be pre-recorded in a memory, or may be provided through a telecommunication line such as the Internet or in a non-transitory recording medium such as a memory card.

  When the operation receiving unit 72 receives an operation of the operation unit 331 by the user, the transmitter-side control unit 73 causes the transmitter-side communication unit 71 to transmit a control signal according to the content of the operation as a wireless signal. That is, the transmitter 3 includes the operation unit 331 provided on the rear surface of the transmitter 3, and the transmitter communication unit 71 transmits a signal according to the operation input of the operation unit 331. Therefore, by operating the operation unit 331, the transmitter communication unit 71 can cause the main unit communication unit 62 to transmit a signal corresponding to the operation input of the operation unit 331.

(2.2) Structure Next, the structure and operation of each part of the load control device 1 will be described.

(2.2.1) Main Body Unit The main body unit 2 includes the switch main body 4 and the handle 5.

  The switch body 4 includes a box-shaped container 41. The body 41 has a rear body 42 and a front cover 43. The body 42 and the cover 43 are molded articles of synthetic resin. The body 41 is configured by connecting the body 42 and the cover 43.

  The cover 43 is provided with a pair of mounting claws 45 at the upper and lower sides of the left side surface so as to be detachably attachable to the mounting frame 8 used when fixing the embedded wiring fixture to the construction surface. A pair of mounting claws 45 is provided at the center in the vertical direction of the right side surface. Thus, the switch main body 4 can be mounted on the mounting frame 8 by locking the mounting claws 45 in the mounting holes 81 of the mounting frame 8, and the switch main body 4 can be mounted on a wall surface or the like using the mounting frame 8. It can be fixed at 100 (see FIG. 3). The plate 9 is attached to the front surface of the mounting frame 8, and the front surface of the load control device 1 (for example, the front surface of the handle 5 or the transmitter 3) is exposed from the opening 91 of the plate 9.

  The movable bar 44 is provided on the front surface of the cover 43 at a position on the right side of the central portion in the vertical direction. A penetrating portion is provided on the right side of the movable bar 44 on the front surface of the cover 43, and a display portion 47 is disposed in the penetrating portion. The display unit 47 is formed of a translucent lens formed of a transparent synthetic resin (for example, an acrylic resin). The shape of the front surface of the display unit 47 is an oval shape that is long in the vertical direction. The display unit 47 may be translucent, may be a translucent translucent member, or may be a colored translucent member. Moreover, the display part 47 is not limited to synthetic resin, You may form with glass etc. FIG.

  On the front surface of the cover 43, at the left end of the central portion in the vertical direction, a shaft portion 46 for rotatably supporting the handle 5 is provided. At the upper and lower portions of the front surface of the cover 43, spring pieces 48 for pushing the handle 5 forward are integrally provided.

  A through hole 49 is provided on the lower side of the shaft 46 on the front surface of the cover 43. The through hole 49 penetrates the front wall of the cover 43 in the front-rear direction. Inside the housing 41, photodiodes of the main body side communication unit 62 are disposed so as to be in the through holes 49.

  The handle 5 is formed of a synthetic resin in a rectangular shape in a front view. On the rear surface of the left side portion of the handle 5, a bearing 51 for rotatably supporting the shaft 46 is provided (see FIG. 2). A protrusion 52 is provided on the back surface of the handle 5 at a portion facing the movable bar 44. When the handle 5 is attached to the housing 41, the handle 5 is rotatable around the shaft 46.

  When the user presses the end of the handle 5 opposite to the side supported by the shaft 46 (right side), the handle 5 rotates about the shaft 46. When the protrusion 52 of the handle 5 presses the movable bar 44 by the rotation of the handle 5, the on / off state of the push-button switch built in the container 41 changes. Thereafter, when the user's hand separates from the handle 5 and the force pressing the handle 5 disappears, the handle 5 moves forward under the elastic force of the spring piece 48. As a result, the movable bar 44 returns to the original position, and the on / off state of the push button switch built in the container 41 changes.

  At the left end of the front surface of the handle 5, a projecting portion 53 that protrudes forward is provided. The projecting portion 53 is provided with a through portion 55 (see FIG. 2) which penetrates the projecting portion 53 in the front-rear direction at a portion corresponding to the through hole 49 of the cover 43. A strip-shaped light receiving cover 54 which is elongated in the vertical direction is attached to the projection 53. The light receiving cover 54 is formed of a synthetic resin that has a light transmitting property to infrared light and a light shielding property to visible light, and the through portion 55 is covered by the light receiving cover 54. . Therefore, the light signal (control signal) transmitted from the transmitter 3 can be received by the main unit communication unit 62, and the main unit communication unit 62 can be made less noticeable from the outside. Further, protrusions 531 are provided on the upper and lower portions of the right side surface of the projecting portion 53, respectively.

  A through hole 56 penetrating the handle 5 in the front-rear direction is provided on the right side of the front surface of the handle 5 at a position facing the display unit 47 of the container 41. A translucent lens 57 (body-side light guide) is attached to the back of the handle 5. The translucent lens 57 is made of a molded article of transparent synthetic resin (for example, acrylic resin). The translucent lens 57 is provided with a projecting portion 571 having an oblong shape whose shape in front view is long in the vertical direction. The translucent lens 57 is fixed to the back surface of the handle 5 in a state where the projecting portion 571 is inserted into the through hole 56. Thereby, in a state where the handle 5 is attached to the housing 41, the light emission of the display unit 47 is irradiated to the front side through the transparent lens 57. That is, the handle 5 which is a movable part has a translucent lens 57 (main body side light guide part) for guiding the light of the display part 47 to the light guide part 35. Therefore, by providing the translucent lens 57 on the handle 5, the display unit 47 can be provided on the switch body 4, and the configuration of the handle 5 can be simplified as compared with the case where the display unit 47 is provided on the handle 5.

  Further, in the present embodiment, the handle 5 which is a movable portion is located at one end (left end) in a certain direction (in the present embodiment, a short direction of the handle 5 and a direction parallel to the horizontal direction) , And is rotatably supported with respect to the switch main body 4 which is a fixed part. And the handle 5 has the light guide part 35 which is a main body side light guide part in the other edge part (right end part) in said direction. As a result, the light of the display unit 47 is output through the translucent lens 57 at the end opposite to the end that is rotatably supported by the handle 5. Therefore, based on the light output through the light transmitting lens 57 or the light guide 35, the user can determine the end portion to which the handle 5 is to be operated.

  The main-body-side light guide is not limited to the transparent light-transmitting lens 57, and may be a translucent light-transmitting member or a colored light-transmitting member. Moreover, the main body side light guide part is not limited to the synthetic resin translucent lens 57, and may be formed of glass or the like.

  Further, an iron piece 58 (a member to be attracted) to be attracted by the magnetic force of a magnet 34 (see FIG. 6) incorporated in the transmitter 3 is attached to the back surface of the right side portion of the handle 5. Since the transmitter 3 has the magnet 34, the transmitter 3 can be attached to a portion formed of a ferromagnetic material such as iron and used.

  In the present embodiment, although the suctioned member made of iron pieces is attached to the handle 5, it is not limited to the iron suctioned member and is made of a ferromagnetic metal such as iron or an alloy thereof. It is also good.

(2.2.2) Transmitter Next, the structure of the transmitter 3 will be described based on FIGS. 1 to 3 and 5 to 7.

  The transmitter 3 includes a transmitter main body 30 which is a molded article of synthetic resin. The transmitter 3 is attachable to and detachable from the handle 5 which is a movable part. By holding the transmitter 3 on the handle 5, the size of the front surface of the load control device 1 can be reduced compared to the case where the transmitter 3 is held on a part other than the handle 5.

  The transmitter main body 30 is formed in a flat rectangular parallelepiped shape, and an opening 301 is provided on the rear surface of the transmitter main body 30. The shape and size of the front surface of the transmitter main body 30 are formed in substantially the same shape and size as the portion of the front surface of the handle 5 excluding the projection 53. Inside the transmitter main body 30, a printed circuit board 32 (see FIGS. 6 and 7) and a battery such as a button battery which is a power supply of a circuit formed on the printed circuit board 32 are accommodated. The printed circuit board 32 is formed with circuits such as a transmitter communication unit 71, an operation reception unit 72, and a transmitter control unit 73. The light emitting diode of the transmitter side communication unit 71 is mounted on the top of the printed board 32, and a through hole 303 for exposing the light emitting diode is provided on the upper side surface of the transmitter main body 30. The printed circuit board 32 is fixed to the transmitter main body 30 using, for example, a flat screw. Therefore, since the difference in level between the surface of the printed circuit board 32 and the head of the flat head screw can be reduced, the gap between the membrane sheet 33 disposed on the back side of the printed circuit board 32 and the printed circuit board 32 can be reduced. is there.

  A membrane sheet 33 is attached to the rear of the transmitter body 30, and the membrane sheet 33 covers the opening 301 on the rear surface of the transmitter body 30. The membrane sheet 33 is formed in a plate shape by a transparent synthetic resin, and has flexibility.

  In the membrane sheet 33, the translucent region 332 corresponding to the projection 571 of the translucent lens 57 provided on the handle 5 is transparent. In the membrane sheet 33, portions other than the light transmitting region 332 are white. Therefore, the inside of the transmitter main body 30 can be hidden by the membrane sheet 33.

  On the surface of the membrane sheet 33, five operation parts 331 which respectively project in a dome shape are provided. In the membrane sheet 33, circular movable contacts are formed by applying conductive ink on the back sides of the five operation portions 331, respectively. On the other hand, on the printed circuit board 32, a pair of fixed contacts are formed by printing, for example, carbon paste at the portions corresponding to the five operation portions 331, respectively. Here, the switch is configured by the pair of fixed contacts and the movable contact.

  When the user presses the operation unit 331 to bring the movable contact formed on the back side of the operation unit 331 into contact with the pair of fixed contacts, the pair of fixed settings are electrically connected via the movable contact, so the switch is turned on. become. On the other hand, in a state where the operation unit 331 is not pressed, the pair of fixed contacts are electrically opened, and the switch is turned off. The operation receiving unit 72 of the transmitter 3 monitors the on / off states of the five switches, and outputs an operation signal to the transmitter-side control unit 73 when the switch is turned on. When the transmitter-side control unit 73 receives an operation signal from the operation receiving unit 72, the transmitter-side control unit 73 causes the transmitter-side communication unit 71 to transmit the control signal to the switch body 4 according to the user's operation. As described above, in the present embodiment, since the switch is configured by the pair of fixed contacts formed on the printed circuit board 32 and the movable contact formed on the membrane sheet 33, when using an existing switch such as a tact switch The transmitter 3 can be made thinner than in FIG.

  In addition, a decorative plate 31 formed of a translucent synthetic resin (for example, an acrylic resin or the like) is attached to the front surface of the transmitter main body 30 by a method such as adhesion or ultrasonic welding. The transmitter main body 30 is provided with a through hole 303 which penetrates the transmitter main body 30 in the front-rear direction at a portion corresponding to the projecting portion 571 of the handle 5. A lens portion 312 inserted into the through hole 303 is integrally provided on the rear surface of the decorative plate 31. The lens portion 312 is in the form of a column formed in an oval shape when viewed from the rear, and protrudes rearward from the rear surface of the decorative plate 31. Further, on the front surface of the decorative plate 31, a projecting portion 311 projecting forward is provided at a portion corresponding to the lens portion 312. Here, the light guiding portion 35 for guiding the light of the display portion 47 to the front side of the transmitter 3 is configured by the lens portion 312 and the protruding portion 311. The light guiding unit 35 guides light from the rear surface side to the front surface side of the transmitter 3 and can output light incident from the rear surface side of the transmitter 3 from the front surface side.

  In the present embodiment, the decorative plate 31, which is a member constituting the front surface of the transmitter 3, and the light guide 35 (transmitter-side light guide) are integrated components. By fixing the decorative plate 31 to the transmitter main body 30, the light guiding part 35 is fixed to the transmitter main body 30, so the structure for fixing the light guiding part 35 to the transmitter main body 30 is referred to as the transmitter main body 30. There is no need to provide it, and the free space inside the transmitter main body 30 can be expanded. Moreover, the loss of the light between the decorative plate 31 and the light guide part 35 can be reduced by making the decorative plate 31 and the light guide part 35 into one component. Therefore, the light quantity of the light output to the front side of the transmitter 3 through the light guide part 35 can be increased.

  In addition, although the surface process for emitting uniform light is given to the front surface of the protrusion part 311, such surface process is not essential. The shape of the light guiding portion 35 can be appropriately changed as long as it guides light from the rear side to the front side of the transmitter 3.

  The decorative board 31 of the present embodiment is manufactured, for example, using a two-color molding technique. For example, the decorative plate 31 can be integrally formed by first molding the lens portion 312 and molding a plate-like portion on one end side of the lens portion 312.

  A magnet 34 is housed inside the transmitter main body 30 at a position corresponding to the iron piece 58 attached to the handle 5. The magnet 34 is, for example, a rare earth magnet such as a neodymium magnet or a cobalt magnet. The transmitter main body 30 is provided with a housing recess 304 for housing the magnet 34. In the transmitter main body 30, the protrusion provided on the peripheral wall of the housing recess 304 is deformed by heat or the like to form the locking portion 305, and the end of the magnet 34 is pressed by the locking portion 305, whereby the magnet 34 is formed. It is fixed to the transmitter body 30.

  Further, grooves 302 (see FIG. 2) into which the protrusions 531 provided on the protruding portion 53 of the handle 5 are inserted are provided at the upper and lower portions of the left side surface of the transmitter main body 30.

  In the present embodiment, the lens portion 312 is provided integrally with the decorative plate 31. When the lens unit 312 is a separate body from the decorative plate 31, a structure for fixing the lens unit 312 to the transmitter main body 30 is required. However, in the present embodiment, the lens unit 312 is integral with the decorative plate 31. The structure for fixing the lens unit 312 to the transmitter main body 30 is unnecessary. As a result, a space for housing the magnet 34 can be secured inside the transmitter main body 30, and in the present embodiment, the magnet 34 is incorporated in the transmitter 3. Therefore, the transmitter 3 can be attached to an iron case such as a refrigerator or a desk, and the usability of the transmitter 3 can be improved.

(2.2.3) Usage method of load control device The load control device 1 of this embodiment is fixed to the construction surface 100 and used. The switch body 4 is fixed to the work surface 100 using the mounting frame 8, and the plate 9 is mounted on the front side of the mounting frame 8. The handle 5 is rotatably attached to the switch body 4. The transmitter 3 is attached to the handle 5. The transmitter 3 is attached to the handle 5 in a state where the groove 302 of the left side surface of the transmitter body 30 is aligned with the protrusion 531 of the handle 5, and is held by the handle 5 by the magnetic force of the magnet 34.

  When the transmitter 3 is attached to the handle 5 and the right side of the transmitter 3 is pushed, the handle 5 is rotated together with the transmitter 3, and the projection 52 of the handle 5 pushes the movable bar 44. Then, the push button switch housed in the container 41 is pressed.
