It has a stop projection 9. The locking projection 9 of the embodiment is formed in a brim shape, and two anti-rotation projections 10 serving as anti-rotation means are projected from the edge portion of the opening 21. A fitting protrusion 11 is provided so as to correspond to the module. Further, a through hole 24 is formed so as to pass through the knobs of the switches 6 and 18, the reset switch 19 and the like.

The block mounting base 3 has a hole 12 that fits the bottom portion 23 side of the block cover 2 and locks the locking projection 9 on the edge. Reference numeral 30 is a mounting notch formed on the edge portion, and 30a is a retaining piece for the mounting screw. Both ends of the holding plate 4 are attached to the back surface side of the block mounting base 3, and the opening 21 side of the block cover 2 is held and fixed at the intermediate portion. The embodiment is made of metal, and the printed wiring board 1 is also pressed and fixed at the same time via the insulating sheet 20, but the rotation stop projection 10 of the block cover 2 can be inserted and the printed wiring board 1 and the control printed wiring board 15 are connected. It is formed to have a width that can form a gap sufficient for passing the tape tape electric wire 7, both ends are bent into a Z shape, and are fixed to the block mounting base 3 by screws 13. Further, the rotation stop projection 10 is locked in the notch hole (not shown) formed in the side portion of the holding plate 4, so that the block cover 2 is surely stopped from rotating and is prevented from coming off.

Reference numeral 14 is a support body that is mounted on the block mounting base 3 with screws 17 to support the control printed wiring board 15 on which the electronic component 16 is mounted. 4 and 5 show how the light receiving block is attached to the ceiling 34. The main body 31 is tubular and has a brim 35 at an opening edge portion, is fitted into an embedding hole 39 of a ceiling 34, and is fixed to the ceiling 34 by a fitting 33. A pair of mounting pieces 37 provided with mounting screws 38 are mounted in the main body 31, and the notches 30 of the block mounting base 3 are locked and fastened to the mounting screws 38. Reference numeral 32 is a terminal block on the power supply side and the load side, which is supported by the support body 14 and projects outside the main body 31, 36 is a panel for covering the front surface of the block cover 2, 40 is a kick spring (not shown) on the main body 31. ) Is a decorative frame that is attached by () to support the panel 36.

FIG. 6 shows an example in which a remote control device is used to control the lighting equipment, 41 is a portable transmitter with a built-in light emitting block, 42 is the light receiving block of this embodiment mounted on the ceiling 34, and 43. Is a lighting device whose lighting is controlled by the operation of the light receiving block 42. According to this embodiment, the block cover 2 is fitted into the hole 12 of the cover mounting base 3, the printed wiring board 1 is fitted into the block cover 2, and the block cover 2 is held and fixed by the holding plate 4. Since it can be assembled, the assembly work is easier than before.
